Dynamites and Their Manufacture.
In the issues of June 23 and 30 appeared technical
unt of the manufacture of nitro-glycerine and
dynamites. Continuing this subject of explosive com-
pounds comes mention of gelignite, which consists of
65?i gelatine and 35% absorbing powder, referred to
in the issue of June 30. These three explosives —
blasting gelatine, gelatine dynamite and gelignite —
are closely related. They all consist of the variety
of nitro-cellulose known as collodion-cotton dissolved
in nitro-glycerine, where necessary made up with
varying proportions of wood pulp, some nitrate or
other material of corresponding character.
A later explosive of the combined gun cotton and
nitro-glycerine series is cordite. Its proportions are
58% nitro-glycerine, 37% gun cot toll, 5% vaseline. In
its manufacture the guu cotton is depVived of moist-
ure to 1%; to 28 pounds of gun cotton are added 43
pounds nitroglycerine. These t^vo ingredients are
hand-mixed, then put through an incorporating ma-
chine with 16 pounds acetone. When these ingredi-
ents have been worked into the form of dough 4
pounds of vaseline are added; the incorporation is
continued for seven hours, when the plastic mass is
placed in a special press and forced through a hole,
issuing from the press in the form of a thread or, in
larger sizes, of a cord. The extruded cordite is wound
on a drum as it issues from the press and is then taken
to a drying house, where it is subjected to a tempera-
ture of 100° P. from three to nine days. By this means
the solvent is evaporated and the manufacture of the
cordite completed. Another class is those derived
from the nitrated hydro-carbons, benzine, toluene,
naphthalene and phenol. Nitro-benzine enters into
the composition of several, including tonite No. 3,
roburite, securite and bellite. Tonite consists of finely
divided and macerated gun cotton incorporated with
finely ground nitrate of barium, recrystalllzed. It is

made by treating carbonate of barium with nitric
acid. A given weight of wet, purified gun cotton,
after being finely pulped, is intimately mixed under
edge runners with the same weight of nitrate until the
ingredients have become thoroughly incorporated and
formed into a paste, then pressed into cartridges
having a recess at one end for the insertion of the de-

tonator, the cartridges being finally wrapped in par-
affined paper. Tonite No. 2 is a variety of the fore-
going, with the addition of charcoal. Tonite No. 3
consists of 19% of gun cotton, 13% of di-nitro-benzol
and 68% of barium nitrate. It has a slower explosive
action than some other varieties, and is better
adapted for blasting in soft formations.
Roburite is a Sprengel explosive ; that is, it con-
sists of two component parts, non-explosive in them-
selves, but which, when mixed together, form a
powerful explosive. Dr. Sprengel's idea was to mix
the two ingredients together at the moment of use.
This mode of procedure could not, of course, be
adopted, as the user — generally a miner or a quarry-
man — would require to be a practical chemist. Rob-
urite consists of ammonium nitrate and chlorinated
di-nitro-benzol; nitrate of ammonia is dried and
ground, the melted benzol added and incorporated
with it until an intimate admixture is obtained. The
compound is then made up into cartridges, which are
waterproofed, roburite being deliquescent, due to the
nitrate of ammonia. Its explosion can only be
effected by a detonator. Securite is another explo-
sive of the Sprengel class, and consists of a mixture
of 26 parts meta-di-nitro-benzol and 74 parts ammo-
nium nitrate. A variety of this explosive known as
flameless securite consists of a mixture of nitrate
and oxalate of ammonia and di-nitro-benzol.
Bellite consists of a mixture of nitrate of ammonia
with di-nitro-benzol. It absorbs little moisture from
the air after it has been pressed into cartridges
while in a heated condition. Like roburite, it is a
safe explosive as well as a powerful one. Another
explosive of this class is ammonite, which consists of
a mixture of ammonium nitrate, paraffine wax, resin
and di-nitro-naphthalene. The nitrate is heated and
pulverized while hot and mixed with the naphthalene.
The mixture is then granulated, sifted and pressed
into tubes, which are afterwards filled with the same
composition in a granulated condition.

The 79th annual meeting of the American Institute
of Mining Engineers will be held at Sydney, Cape
Breton, and Halifax, Nova Scotia, August 21st-29th,
under the auspices of the Canadian Mining Institute.
The recent Milwaukee Mining Congress made a
mistake in indorsing the Torrens system of legal
transfers. That system usually requires a guarantee
fund to make good the blunders and mistakes growing
out of Torrens titles. Legal titles to mining prop-
erty are too uncertain and unsettled for any State or
county to undertake to insure or guarantee Torrens
titles to mining property.
This paper is always pleased to receive and pub-
lish contributions of interest to its readers, and where
deemed desirable illustrations, photos or sketches
from which engravings may be made would be accept-
able in further embellishment of the subject. De-
scriptions of appliances and records of experience
are always interesting to readers everywhere, and
oftentimes of great practical value.
A mining claim is realty, and a man has a legal
right to hold as many claims as he can do annual re-
quired work on ; yet it is not wise to attempt to grab
or hold the whole countryside. That is a habit and a
bad one. A locality where one man or a few men
hold nearly all the claims is not sought by investors,
and wholesale claim holders thus defeat their own
purpose. "Just doing assessment work" will keep
a camp poor forever. It is development work that
makes a camp, and a man who holds his claims to sell
at a big profit, just as he would a corner lot in a rapidly
growing town, must demonstrate intrinsic, value or
continue to be " claim poor."
The event of the week has been the advance in
silver and lead, the former indicating withdrawal of
deposits for export. In this regard it is of interest
to note that New York City reports a greatly de-
creased number of outstanding silver certificates,
thus indicating a cessation of speculation in silver on
the Stock Exchange by means of such certificates.
They have been so used since their introduction in
1889, but it would now appear that Eastern manipu-
lators consider that the price of silver can be better
"ustained by control of the supply than by making
the metal the subject of certificate speculation on
he exchange.
Railroad Restriction.
California mineral development suffers from rail-
road restriction. In other States the railway com-
panies advertise the resources of the area from which
they draw support, rightly reasoning that their own
prosperity will be proportionate to that of the coun-
try from which they naturally expect to get business.
In California the Southern Pacific Company has
always acted as though it were afraid that the State's
mineral area should be exploited, a vigorous silence,
a rigorous reticence being constantly maintained.
For aught that great corporation emits no one
would know that there was a mineral product in the
State. Unlike any other commonwealth, whatever
advance is made in the mineral development of the
State is not made because of the railway company,
but in spite of it.
Wherever it can it comes with a heavy hand on any
California mineral producing industry. The latest
from San Bernardino county is an example. In that
county borate of lime is mined to the amount of about
900 tons per month, loaded at the mine in cars and
hauled eleven miles by the borax company over its
own road to Daggett, whence it is shipped to the
refinery on San Francisco bay. It is considerable of
an industry in a small way, one of those things that
helps to develop a State, turning into money an inert
mass. Formerly the marsh deposits of California
and Nevada were the chief sources of borax. Mining
and scientific development showed that the stratified
rock formation of borate of lime in southern Califor-
nia could be made to yield profitably, by modern pro-
cesses.
Till recently the freight rate from Daggett
to the refinery — about half the length of the State —
was $6.50 per ton. The S. P. Co. has raised the rate
to $29 per ton. This, of course, is prohibitive, so the
Alameda refinery must close. Meanwhile, if the San
Bernardino county borax mines continue production
the S. P. Co. will get the " long haul ;" it will carry
the crude borate to Galveston, Texas, over its ' ' Sun-
set " lines. At Galveston it will be shipped by steamer
to New York City — carried over 3000 miles, and at a
freight rate cheaper than it would be taken from one
California county to another.
This is not an isolated case, nor is the matter exag-
gerated. It is merely characteristic, and illustrates
how mistaken policy retards and restricts the devel-
opment of a State. Anywhere else such action
would be impossible. It was supposed when the
Santa Fe got its supplicated favors from San Fran-
cisco and the San Joaquin valley that that corpora-
tion would and could prevent the creation or con-
tinuance of such arbitrary action, but events in
the last few weeks show that in California railroad
operation combination is preferable to competition,
and the cinch is tighter than ever.
It will not be uncommon to hear of fires in mills
and mining towns for the next ninety days, and while
disaster by fire is in a measure unavoidable, it would
seem that most of the loss so entailed could be avoided
by due precaution and the exercise of preventive
measures. As usually built, many mining towns in-
vite fire. The mine or mines that are the cause of
the town's existence are usually at the head of a nar-
row canyon that widens down the grade and through
which the wind sweeps. Should the fire start at the
head of the canyon, it usually burns as long as there
is anything left, for the fire protection is generally
inadequate, and, despite heroic exertion, the disaster
is often complete. The best protection against fire
is to recognize its imminent probability and to have
every procurable contrivance on hand to check it at
the start. Time is worth about $25,000 a second
during the first few moments after a fire is discov-
ered— a well directed hand grenade or a stream from
a chemical engine will do more to put a fire out in the
first few minutes than a whole department after it
has got under way. The manner of mill construction
and the carelessness born of continued escape from
the inevitable, make destruction more complete.
There is nothing more likely to entail terrible loss in
a mill or mine or mining town than fire, and nothing
is more loosely guarded against in many instances.
In mill construction, especially, in these days of bet-
ter transportation, it is well to make all due provis-
ion against contingency of fire ; it is more expensive
to so build, but still more expensive to be burned out.
One common mistake is in tryiug to get everything
under one roof ; then, if anything goes, it all goes,
and the bigger the plant the greater the propor-
tionate danger of such disaster. One thing is to be
reckoned on : a fire is sure to start some time or
other, and so far as possible the mill should be so ar-
ranged that when fire does break out, even if it can
not be got under control, it will not consume the en-
tire building.
Must Learn by Experience.
Now that the northern transportation boom has
been worked for all it was worth it ought not to be
necessary to continue daily statements at so much or
so little per published line concerning the return of
men with "big bags of gold" in their possession.
The truth has been told in these columns about those
northern gold fields, but many people want to believe
what they themselves imagine. It is occasionally
surprising what silly stuff men will believe, men who
are ordinarily intelligent enough to discriminate.
The following from the Juneau (Alaska) Dispatch of
the 23d ult. is illustrative:
The Alaska Commercial Company's steamship Ex-
celsior arrived this morning from Valdes, Cook's Inlet
and the Westward. She carried a number of passen-
gers bound for the south. Among them was Dr.
W. D. Northrup of San Diego, Cal., who, with some
twenty other residents of that vicinity, says he was
induced to go to Yakutat bay by stories of beach and
gulf sands that carried 18 ounces of platinum to the
ton, besides sufficient gold to pay all working ex-
penses. These stories were told the San Diegans by
two prospectors, who wintered last year at Yakutat
and who claimed to have lost all their stores in the
tidal wave of last autumn. They sold claims to many
of the party at various prices, in one instance secur-
ing $600 for a one-fourth interest. The buyers will
now dispose of these claims at a very low figure.
Dr. Northrup says that 360 tons of these sands will
produce one ton of concentrates, carrying an ounce
of platinum and $4 in gold. There is only one mine at
Yakutat and it produces less than $1.50 a day to a
man. The party spent two months discovering this
sad fact, and they are now returning to San Diego.
They are trusting that they may get there before the
two prospectors leave.
;
The fact that incorporated mining companies in
this country paid over $40,000,000 in dividends dur-
ing the first half of this calendar year will attract
considerable attention in the East, where investors
will contrast such showing with the unprofitable
150,000 miles of railroad, with over $10,000,000
liabilities. It is a most favorable showing, and will
go far toward substantiating the claim that the min-
ing industry, compared with other industries, has
paid more dividends than any other. In the $40,-
000,000 are only announced dividends of incorporated
companies. That aggregate falls far short of the
total, for there are many companies profitably en-
gaged in mining who make no announcement. This
is largely due to the old fear in all competitive indus-
tries that some competitor would find out how profi-
able the business was, and so hurt him who pro-
claimed his prosperity by cutting into his profits.
Such reticence is a survival of former fear in that
regard, a fear that should be groundless in the one
industry of all others that has least to dread from
competition, and that depends for its progress
largely upon the increase of the number devoting
attention to it.
Next in importance to California of the discovery
of gold is the present exploitation of its oil wealth,
supplying the one lacking requisite of cheap fuel, and
making possible an era of manufacturing. And when
is considered the variety of bye-products procurable
from petroleum,it is manifest that even fuel supply may
become secondary in commercial importance to the
value of the articles derivable from the crude petro-
leum now being pumped so abundantly throughout a
large area of the State.
It has been often said with considerable truth that
a foreigner could live on what an American threw
away. While this is true in many instances the say-
ing does not apply to machine methods, to mining or
manufacturing, to industrials in general. American
manufacturers and engineers practice an economy in
materials and labor that is unequalled abroad, and in
no country are more economical methods of produc-
tion than in the United States.

Pyritic smelting comprises the smelting of raw py-
ritic ores direct, in a blast furnace without the use of
carbonaceous fuel, utilizing as a source of heat the oxida-
tion of part of the sulphur and iron contents of the ore it-
self. Pyrrhotite and chalcopyrite may serve instead of
pyrites for this purpose.
FOR calculating the capacity of any piston pump,
multiply the area of bore of cylinder of pump by
the length of stroke, and that result by the number of
strokes per minute the pump is working. This gives
the quantity of water in cubic inches ; dividing this by
231 gives a total capacity of pump per minute in gallons
and fractions of a gallon.
With care there is little danger of poisoning from
cyanide. The chief source of possible trouble in that
regard would seem to he that insoluble cyanide salts —
cyanide of zinc— for instance, may mix with the slimes,
not being well washed out, thus forming hydrocyanic gas
when sulphuric acid is poured on. In case of inhalation,
a prompt subcutaneous injection of hydrogen peroxide
will be effective antidote.
No pdmp will draft hot liquids any distance, for
the reason that the vapor or steam rising from the
liquid passes through the suction pipe into the pump
and fills it with vapor instead of water. There-
fore,, for pumping hot liquids the pump should be
placed as near as practicable, forcing the liquid
upward instead of lifting it by suction. A hot wator
pump always requires metal valves throughout.
There are several simple tests for feed water, any of
which can be used by those in charge of steam boilers.
The hardness or softness of water is easily determined by
dropping a little alcohol that contains soft soap to satu-
ration. If the water is hard it will turn milky white,
but will remain clear if it is soft. For carbonate of lime,
five to ten drops of oxalate of ammonia should be added
to the water in a test tube ; if lime be present the water
will have a clouded or milky appearance, and after stand-
ing a few hours a precipitate will be found at the bottom
of the tube. A few drops of nitrate of baryta will reveal
the presonce of sulphate of lime or sulphuric acid, by
forming a white precipitate. When a drop of perman-
ganate of potash is put into the water, it colors it to a
bright violet rose color at first, but if decomposed or-
ganic matter is present the color changes to a dull yel-
low. If iron is held in solution, a few drops of a solution
of prussiate of potash produces a blue color in the water.
To make a spark coil for a gasoline engine, to be used
eithor in connection with a battery or a 50-volt direct-
current circuit, wind about three pounds of No. 14 wire
on a one-inch coro of soft iron wire. Use four or five cells
of a good sal-ammoniac battery, or a larger numbor of
potash cells. Connect a 50-volt lamp in series when cur-
rent is taken from a 50-volt lighting circuit ; if alG-candle
power lamp does not give a largo enough spark, use a
32-candle power.
In August, 1873, the average London price of silver
per ounce standard (0.925) was 59 pence; equivalent value
of ounce fine with exchange at par, $4.8065, $1.29334,
equivalent value of ounce fine based on average price of
exchange, $1.28186 ; bullion value of a U. S. silver dollar
at average price of silver, exchange at par, $1.00031 ; com-
mercial ratio of silver and gold, 15.98. At current Lon-
don silver quotations the above figures would be .62196,
.62323, .48104 and 33.23, respectively.
Metaphysical and psychical discussion are doubtless
fascinating forms of research to some minds, but the only
idea in this page is to answer as accurately as possible
questions that come up in the daily lives of our readers ;
questions that are often on the lips or in the minds of
many, who see in some answer the very thing they were
going to inquire about. It is neither our province nor
our purpose to start any argument or discussion on
imaginary or fanciful topics, but to try to make practical
answer so far as possible to questions of general in-
terest.
There is no uniform rule or rate regarding assaying.
An "assay" will cost from 50 cents to $5, according to
what kind it is. The regular California rate for a com-
mon, ordinary assay is $2 ; in Colorado, $1.50. Yet, were
a miner to take a bunch of forty or fifty assays to a Colo-
rado assayer he would probably get the lot done for 75
cents each. The same discount would likely prevail un-
der the same conditions in California or elsewhere. The
University of Arizona does assay work and charges for
it. Arizona assayers pay taxes to support an institution
that enters into direct competition with them.

The Supreme Court of the United States— 102 U. S.,
167 — in the case of the Ivanhoe M. Co. vs. the Keystone,
established the doctrine that Congress in making grants
of school lands to the several States did not depart from
the policy of reserving mineral lands from sale, and that
mineral lands' found within a sixteenth or thirty-sixth
section, known to be such at the time the grant took ef-
fect, did not pass to the State. The Secretary of the In-
terior and the General Land Office, by a uniform line of
decisions, have held that mineral lands do not pass to the
State under the school grants from the Federal Govern-
ment. *
In working a double acting pump, which is
equivalent to two single acting pumps of same diam-
eter, double the power would, of course, be re-
quired, and double the water would be discharged. It is
immaterial whether the water is raised with a large or
small pump, as the theory is that it requires a given
quantity of power to raise a given quantity of water a
given height in a given length of time. Of course, if the
pump is large it must be worked slowly, and, if small, it
can be worked faster; the power required to work a small
pump fast is the same as to work a large pump slow, for
the same given height and quantity.
TO find the head in feet due to friction in a pipe run-
ning full, multiply the length of the pipe in feet by the
square of the number of gallons per minute, and divide
the product by 1000 times the fifth power of the
diameter of the pipe in inches. The quotient, less 10%,
is the head in feet necessary to overcome the fric-
tion. Example : A pipe 4 inches diameter and 4000
feet long is to deliver 200 gallons per minute; what
head of water in feet is equivalent to the friction?

A fine form of blowpipe reduction may be effected as
follows : Flatten out a very small piece of metallic
sodium on a fragment of filter paper; in this roll up the
substance to be examined and wind with a close spiral of
finest iron wire. After the excess of paper is cut off,
slowly burn the roll in the interior of a Bunson flame and
cool in the stream of gas close to the top of the burner.
The product is then treated with a little water in an
agate mortar, when the caustic soda formed is quickly
dissolved and any metal present is left, generally in quan-
tity large enough-for easy examination. Sulphur and
other substances are readily detected in the solution. In
case of silicates and borates, the silicon or boron is loft in
the elementary state and easUy recognized. In caso it is
desired to examine the constituents of tho substances
with the spectroscope, aluminum or magnesium filings
are substituted for the sodium. The reaction is violent,
but, in small quantities, unattended with danger. If it
is desired to use larger quantities, the substance must be
diluted with an indifferent body, as salt when sodium is
used, magnesium oxide with magnesium and aluminum
oxide with aluminum. In this way considerable quanti-
ties may be used in a small iron crucible, and thus
silicates decomposed in a few seconds. With care the
process is even available for quantitative work.
Steam at 100 pounds absolute pressure has a total
heat of 1213 degrees per pound above zero, or 1181 de-
grees above 32. The weight of steam passing through
an engine for this purpose would be 1,000,000 -s- 1181 =
846.7 pounds, and the duty would be taken for the time
it requires for 846.7 pounds of steam to pass through the
cylinder. If the test included the boilers as well as the
engine, and the feed water was taken from the hot-well
at a temperature of 112 degrees F., and passed through a
heater supplied with exhaust steam from an auxiliary en-
gine and the boiler feed pump, it would be raised to 212
degrees, thus calling for 1213 — 212 = 1001 degrees to be
supplied by the boiler, and 1000 pounds under these con-
ditions would require almost exactly 1,000,000 British
thermal units.
The Pittsburgh Reduction Co., at its aluminum works,
uses about as large rotary converters as any manufactur-
ing concern. They are made by the General Electric Co.
A two-phase current is first reduced by transformers to a
pressure of 115 volts. At this pressure it is led into the
converters, which give out the continuous current at 160
volts ; the plant having a total capacity of over 10,000
amperes, equivalent to an output of about 2000 H. P.
The G. E. Co. makes a three-phase converter, a 16-pole
600 kilowatt machine running at 188 revolutions per
minute. In this machine the pole-breadth is 72% of the
pole-pitch, yet the ratio of conversion is 71.8; the volt-
ages at the respective sides being 115 and 160. The
armature diameter is 100 inches, the core length 8.25
inches, giving 4.3 square inches of peripheral surface per
kilowatt. The temperature rise after 17 hours with a
conversion output of 575 kilowatts was 15° C. in the
armature, 23° C. in the field magnets. The average
flux-density in the gap was 69,000 lines per square inch.
The power necessary to raise water depends upon the
height to be overcome and the quantity to be delivered.
A gallon of water weighs about 8J pounds ; consequently,
if ten gallons of water are required to be lifted 1 foot per
minute, 85 pounds power will be exerted ; and the
same proportion will remain as the height is increased.
The following formula will be found useful in determin-
ing the necessary power to work one pump : Having
found the number of gallons desired per minute, multiply
this number by 8.35 (weight of one gallon of water); then
multiply the product by the height in feet to which the
water is raised, and it gives the number of foot pounds.
Divide the product by 33,000(1 H. P.), and the result is
the horse power, or its fractional part, required to do the
work. To this a liberal allowance must be added for
friction — say, 15%. A 1 H. P. steam engine will elevate
50% more water than a single horse working on a horse
power. It is essential that the inlet or suction pipe to a
pump should be air-tight to secure its successful opera-
tion. The theory is that water can be raised by suction
about 33 feet perpendicular height, but, practically, 20
feet is all it is safe to recommend. The diameter of the
suction pipe should not be less than about half the diam-
eter of pump cylinder. When the suction pipe is near
the extreme limit of, say, 20 feet vertical height, it should
be even larger than this. Suction pipes may be extended
almost any distance horizontally ; where this occurs a
check valve is desirable. Elbows or short turns should
be avoided as much as possible in either suction or dis-
charge pipes.
The high expansion ratios used in compound and mul-
ple-expansion engines, and the high temperature of steam
at 160 to 180 pounds pressure unite to cause a greater
range of temperature in the cylinders than formerly.
These conditions make the internal losses important, and
it is to superheating that the steam engineer looks for
help to reduce these losses. Many of the old objections
to superheating may now be met in a manner formerly
not possible. Improved lubricants, capable of resisting
the action of high temperatures, are to be had ; the best
forms of metallic packing require less lubrication than
was formerly needed, and the superior workmanship of
modern engines assists in rendering smooth operation
possible. Excessive superheating is by no means neces-
sary. When the steam is heated 75° to 80° F. above the
temperature due to its pressure, an excellent economy is
produced without injury to the working parts, the sav-
ing usually ranging about 20%. With engines normally
requiring 14 to 15 pounds of steam per horse-power hour,
the consumption with 75" superheating falls to 11 and 12
pounds respectively ; while for engines especially con-
structed for use with high degrees of superheat, the
steam consumption per horse-power per hour has fallen
90 pounds. The principle that steam cannot be super-
heated until it is removed from the boiler in which it was
made, probably holds good for steam that is in a quiet
state, but in some upright boilers now in use, as the tubes
extend above the water line and are filled with heated
gases, the steam as it passes these becomes superheated
on its way to the steam pipe, but such steam is in reality
removed from the water, although still in the same boile^

NTMliKK [I.— OONOL1 I '
In last week's issue was given some general ac-
count of the modern exploitation of ancient mines in
the Stale of Guanajuato, Mexico. On the front page
of this issue, and the page opposite this, are further
interesting views in and around the Sirena mine,
which is one of the properties now being developed
in accordance with up-to-date mining methods by the
Guanajuato Consolidated Mining & Smelting Co.,
whose main oftiee is No. :!."> Wall street. New York
City.
The Sirena mine is located } mile from the city of
I I'llail.' I.:- i « ol Led lor o\ el' lllll \ ears.
It was formerly worked through a vertical shaft,
which was sunk to a depth of 1)00 feet. At a depth
of 150 feet this shaft cut the ledge, which dips at an
angle of about 4.V to the west. At this point a level
was run and stoping began above this level. In 1856
a crosscut tunnel was run for a distance of 2001) feet
and cut this shaft at the above-mentioned 450-foot
level, since which time the mine has been worked
almost entirely above this level, as the crude hoisting
plant made it very difficult to keep the water out of
the lower levels. A drift was run on the vein from
this shaft 3000 feet. Stoping had been done at inter-
mediate points all the way from one end of this drift
to the other, and up to 1897 work was still being
done in these drifts above the present level, the lower
workings being entirely submerged with water. The
richer ore in the upper stopes has been extracted.
There is considerable low-grade ore left unstoped,
going about 26 to 30 ounces silver and $3.50 to $10
gold. The vein is composed of quartz, which carries
lime and feldspar. The gold is present in sulphides
of iron, best treated by concentration. The silver is
in the form of sulphide of silver.
In 1899 H. P. Sellon made report on the entire
property, in which he cited the fact that Mexican
mines and their method of management are so en-
tirely different from the general character of mining
in the United States that the system has to be ex-
plained to understand why large bodies of ore have
been left in the mines and not worked by former
owners. As was explained in last week's issue, an
ore of a value of $20 is not worked at a profit to both
the mine and hacienda (custom mill), owing to the
cost of treatment at the hacienda and tributary sys-
tems adopted at the mines, besides the want of
machinery and equipment to save the cost of hauling
and handling, though under modern methods there
would be a profit to the mine and the mill. The trib-
ute system is in vogue, the miners getting 50% of the
value at the hacienda after the charges are paid.
Nearly all work is done by man and mule power,
which takes much time and makes it difficult to ob-
tain large output. The patio process of treatment
is slow and expensive, ore sometimes taking from
three to six weeks to treat under this process,
which, though good for silver, is bad for gold, only
30% of gold value being saved, all gold in sulphurets
being entirely lost. When Mr. Sellon made his re-
port the cost of working on the patio was high, ore
grinding alone costing $5 (Mexican), and the work-
ing of the ore on the patio, chemicals, sampling,
assaying seldom costing less than $5 more, besides
cost of general manipulation, making, altogether,
cost of treatment $14 to $17 per ton, or nearly twice
that of modern milling. A large hacienda with
twenty arrastras can only handle about 18 montones,
or 28 tons, a day, and the ore, after crushing, must
be worked on the patio for two or three weeks, some-
times thirty days, according to the class of ore.
With modern machinery the ore ought to be ground
up for $1.50 (Mexican) and treatment should not cost
more than half as much.
Taking an ore value of $51, for instance, it can be
seen how the cost of working cuts down profit. The
value of $51 (Mexican) ore would be as follows in the
mines under discussion :
Silver $36
Gold 15
Silver value saved in the patio $30
Gold value saved in the patio ■ 5
Total $35
Hacienda charges for treatment 17
Balance $18
Miner's tribute 9
Balance $ 9
Hauling ore to hacienda 2
Gross profit to mine $ 7
After paying superintendents, timbering or stone
pillars, supplies, etc.,- the mine was practically
robbed of its profits, while the hacienda made, with
its enormous charges, a good profit for treatment.
The scale of wages in Guanajuato at the time was
as follows :
Per day,
Mexican.
Assayers $.50
Machinist 1.50
Miners, first $0.75 to $0.85
Miners,' second 0.60
Day laborers on surface 0.25 to 0.30
Superintendents (Mexican).... 5.00
Blacksmith 1.50 to 2.00
Carpenters 1.00 to 1.50
In the patio process the ore is crushed in a Chilian
mill, to go through a screen having four meshes to
the inch. It is then taken to the arrastras, where
\ it is ground fine with water, mercury there added,
and all free silver and gold amalgamated. In those
ores little of the gold or silver is free. The remain-
I der is carried on to a paved open courtyard, or patio,
j where it is mixed with water to the consistency of a
thick mud and treated with salt, sulphate of copper
and hydro-sulphate of soda. This mass is continually
turned, mixed by mules treading it for two or three
weeks — sometimes longer, according to the charac-
ter of the ore. When the ore is adequately desul-
phurized, and the silver formed into a chloride suffi-
ciently to amalgamate, it is sent through a settler
and the amalgam caught and retorted.
The mining laws of Mexico limit the working of a
vein to that portion which the boundary lines of the
claims cover when extended vertically downward, so
that in order to secure a long-lived mine it is neces-
sary to have the locations not only cover the apex of
the lode, but also very extensively cover the terri-
tory on its dip.
M. E. MacDonald, the company's local manager,
reports regarding the Sirena mill and mine :
" In starting up our plant we followed the methods
now in use at the different mills at Pachuca, where
they treat ores of a similar character to ours. Dur-
ing the month of October, 1899, our expenditures for
supplies, labor, etc., were as follows in Mexican
money :
5691 Kilos quicksilver $ 1,400.97

Total cost supplies $ 8,511.22
Total cost Mexican and American labor. 1,764.07
Total cost operation of plant $10,275.29

ber was 1345, dry weight, and calculating from this
amount shows the following statistics on the propor-
tional cost per ton of ore treated .-

month we treated 1430 tons of ore, and calculating
with this amount as a basis shows the following items

Concerning'the first south drift of the Sirena mine,
illustrated on the opposite page, showing the Mexi-
can miners at work, Mr. MacDonald says :
"At present the remains of this enormous body of
ore are being worked on the "buscone" plan, viz.,
each crew of Mexican miners is allowed a certain sec-
tion of stoping ground, where they mine ore at their
own expense and sell the same to the company on
the following conditions : First, one-half the entire
lot of ore is taken by the company outright ; second,
the balance is liquidated in the following manner : A
treating charge, or 'maquila,' of 508 grams silver,
or $20.32, is deducted from the value per ton metric,'
and then the balance is paid for by the company on
the basis of figuring silver at $0.90 per ounce and
gold $6.17 per ounce, Mexican currency."
Of the vertical shaft of San Miguel Manager Mac-
Donald says :
"This main working shaft was sunk by the ancient
miners in the year 1802, and has a total depth
variously stated to be from 825 feet to 1050 feet, and
a diameter of 16 feet, octagon shaped, which is
walled up with masonry to a depth of 614 feet, and
from there down the rock is solid and does not need
support. This shaft connects with the deepest work-
ings in the mine, and was for a long time filled with
water nearly to the main tunnel level above men-
tioned. This water has been hoisted and the work-
ings drained to a depth of 325 feet below the main
tunnel."
Gold Dredging at Oroville, Cal.
Written for the Mining and Scientific Press by H. G. Parsons.
With Oroville as a focus, gold dredging operations
are being extended into contiguous territory and to
the auriferous ground of other streams beside the
Feather river. The locality below Oroville is ex-
ceptional in its formation, and will continue to be the
seat of great activity in dredging operations. It is
here that the Feather river breaks away from the
mountains. The waters have been laying down in
ever-changing channels loose, gold-bearing gravels,
which underlie the present surface of the country.
Some of these channels were discovered in the early
fifties; more are now being located by prospectors
for the dredger companies, and machines are being
built and placed so as to reach these later discovered
channels. It is not necessary that the dredgers be
upon the river or any small tributary; they can be
worked miles away from the stream, provided that a
pit be dug of sufficient size to accommodate the ma-
chine after construction, that this pit be filled with
water and that a sufficient supply of fresh water be
added to keep up the operations of the machine. In
a country ramified by irrigation or mining ditches,
like Butte county, these conditions are easily filled.
Most of the new enterprises are away from present
water courses, but at points where prospecting
operations have demonstrated the existence of good
placer ground.
Two types of dredgers are in use, one of these be-
ing of the steam shovel or dipper class, the other of
the Risdon or Postlethwaite type. These dredgers
are provided with a system of buckets fastened to an
endless movable chain, which passes over sprocket
wheels at the end of an arm, held against the bottom
or side of the gravel pit, where the buckets scoop up
the gravel and convey it to the center of the boat,
where it is dumped into a hopper, the fine gravel
separated from the cobbles, the latter dumped out-
side the boat, the gravel elevated by a centrifugal
pump and made to pass over riffles and plates, thence
into sluice boxes, where about all the valuable ma-
terial is saved. Although varying somewhat in detail,
the working principle is the same in all the dredgers.
The main point is to scoop up the gravel and extract
the gold before the gravel is again dumped into the
waste pile.
The Feather River Exploration Co. is the most ex-
tensive in its operations of any concern now at Oro-
ville. It has three dredgers at work at different
points along the west bank of the Feather, all of the
Risdon type. One of these — the last constructed — is
of greater capacity than its predecessors and re-
quires 100 H. P. for its operation. Capt. Thomas
Couch, the president of the company, was one of the
first to take up this line of dredging in California,
and has had one of the machines in operation since
March 1, 1898. John J. Homlyn is secretary and
assistant manager ; Aug. Berner, superintendent.
This company owns over 1000 acres in the heart of
the auriferous deposit.
The Marigold Dredging Co., composed of New
York men, under the management of Bond Thomas,
is operating a dredger of the Risdon type close to the
stream, opposite the Feather River Co. Their ma-
chine is under the direct superintendence of George
Telford, who had experience in dredging operations
in New Zealand under Mr. Postlethwaite. The oper-
ations of this company have been profitable; they are
building another machine double the capacity of the
first. They have been working since April, 1899.
The Continental Gold Dredging Co. has success-
fully started the largest machine yet installed in the
State. It is of the Bucyrus type, using the endless
chain and bucket, similar to the Risdon machine in
its method of scooping up the gravel, but its system
of washing the gravel and disposing of tailings is dif-

ferent. The operations of this company are in a pit
near the Feather river. No expense seems to have
been spared in making the equipment of this machine
as perfect as possible. The motive power is entirely
electric, and 300 H. P. will be required. This will be
developed through four different motors. Frank
Griffin is superintendent for this company.
The California Dredging Co. is operating a dredger
The Kia Ora Dredging Co. is operating a dredger
of the Risdon type in a landlocked pit 1 mile from
the river and 4 miles or more below Oroville. This
dredger is under the direct management of R. H.
Postelthwaite, the designer and builder of this type
of dredger. It was one of the first enterprises to
start operations so far inland, and after a successful
run of several months has demonstrated that these
yards of gravel in twenty hours' work.
The company owns 360 acres of ground, part
of it being along a gravel channel that yielded
largely in former years. It has been demon-
strated by prospecting that the channel was
little more than scratched by the early placer miners.
E. Peabody and Henry E. Vail will have direct charge
of the dredgers of the above company.

of the dipper type in the Feather river, two miles
below Oroville. This dredger is virtually a large
steam shovel, mounted on a hull and fitted with gold-
saving apparatus. The dredger Plutus, owned and
operated by J. W. Ferris and associates of San Fran-
cisco, is of similar type, and until recently was at
work in the river near the site of the Feather River
Exploration Co. 's plant. The Plutus was probably
working in poor ground. It is now being dismantled i
and will be taken to Rogue river, Oregon.
machines can be manipulated with a limited water
supply.
The Oroville Dredging Co. is the latest in the field,
and is constructing necessary buildings at its seat of
operations J mile from the river, and will soon begin
building one or more of the dredgers it proposes to
put in operation. These, dredgers will use the Ma-
rion steam shovel built at Marion, Ohio, in a
machine of special construction for this work.
It is estimated that each will handle 1500 cubic
W. P. Hammon is one of the pioneers in dredging
operations at Oroville. He has been actively identi-
fied with and has efficiently promoted some of the
most successful enterprises. He is now stimulating
the operations of a company which is about to build a
dredge 3 miles from Wheatland, near the bank of
Bear river. The project is but an indication of the
manner in which dredging enterprises will be spread,
all being locally inspired by the success attending
this species of mining at Oroville.
Summer Outing Scenes.
Fourth of July week, with thousands of city people
out of town, and thousands of country people forsak-
ing scenes of rural activity for the wilds of lake,
mountain and forest, affords a proper occasion for
turning our pictorial attention away from the lines
chiefly pursued. A few camera shots of outing scenes
are therefore offered herewith.
It seems to be a general complaint that the more
retired avenues of vacation travel and repose are
scantly peopled this year. It does not seem
to be a good summer boarder and summer trav-
elers' year. There are perhaps several reasons why
local resorts should be neglected. In the first place
the times are full of action. People are, as a rule,
busy about important concerns which promise reward
for effort. There is a shortage of labor supply, and
many who could steal time for recreation while their
affairs proceeded under others' care, have this year
to do their utmost to promote their own undertak-
ings. Agaiu, it is a time of unusual interest in dis-
tant activity. A large number of those with longer
purses are doing Europe and the Paris Exposition;
many more are seeking long purses at Alaskan
points ; there are hundreds of Pacific Coasters in our
new Oriental possessions. Last of all, perhaps, it is a
general election year and candidates and their friends
are very busy pipe-laying and fence-building. All
these distractions and others akin to
them are reducing the numbers of those
who seek recreation for its own sake
and decimate the ranks of summer idlers.
And yet the delights of air and wa-
ter, forest and mountain, are being
enjoyed by many, and the charms
of changing scenes are not less to those
who are now pursuing them. Our pic-
tures are suggestive of some phases of
far western summering. The rolling
hills, with the mountains beyond, afford
a breadth of view which is inspiring
and uplifting. The piles of rock refuse
thrown up by some hilltop engineering
bespeak the power of man to surpass
mountain barriers, and the waste of
rock and gravel which nature is endeav-

oring to conceal with for-
est shows the repairing by
which Mother Earth cov-
ers her scars wherever
such work is possible.
Two other pictures relate
more directly to outing
— the boats upon the
lake, the temporary
camp upon the hillside —
and need no comment to
those who are now tast-
ing or have enjoyed these
recreations.
Doubtless it is well to
seek rest and recupera-
tion. One can hardly see
a camp of city children,
done to a brown by the
warm kiss of the sun and
hear their happy cries as
they pursue unwonted
pleasures iu the lake or
the woods, without feeling
that there will be brighter

when the schools reopen and bodies bet-
ter fitted to resist weakness and take
on strength during a whole year after-
ward. What is good for the chil-
dren is also good for the elders — respite
from pressing duties, hunger born of the
tonic of the country air and long, sound
slumber caused by physical weariness amid
conditions which make such weariness a
blessing — all these are strong agencies
to repair the nerves, sweeten the temper
and lessen the gravity of life's burdens.
Fortunate are they who can adopt -such
remedies.

The Electrical Precipitation of Gold
on Amalgamated Copper Plates.*
NUMBBK II. — CONCLUDED.
The existence in bath No. 1, containing the com-
mon salt, was somewhat lower than in the
others, but the decomposition of cyanide was not re-
duced by the presence of the salt. The density of
the current in this and all the other experiments was
measured by a mirror galvanometer, with the aid of
a resistance box and the fall of potential by a direct
reading voltmeter. Both instruments were carefully
tested.
When the current was turned on, a black film
which proved to consist entirely of gold appeared
almost instantaneously on the surface of the cathodes.
The addition of sodium amalgam to the mercury baths
caused the rapid absorption of the films of gold, but
it appeared again almost instantaneously on the sur-
face of the cathodes, and continued to grow thicker
and thicker until it formed a black powdery layer which
could not be amalgamated without the addition of
sodium amalgam. It was easy to remove the whole
of the film from the surface of the mercury and of the
copper plate by means of a feather. About half the
gold had been precipitated in this way when the ex-
periment was stopped.
No. 2. — With the same baths and electrodes, but
with the solutions kept at "about 0.3% KCy and 10
ounces gold per ton, a current of 0.30 ampere per
square foot of cathode was passed for 150 hours. The
fall of potential in the baths was 0.75 volt. The black
film on the cathodes appeared and thickened in the
same way as in the previous experiment, but at the
end of the week it was found that the deposited gold
was distributed as follows, in grams :
Bath No 1. Bath No. 2. Bath No. 3-

In form of amalgam

face of the copper
plate 0.180 0.324 0.603
Totals 1.444 1.247 1.289
The amalgam on the plates was somewhat hard and
dry, but adhered well. It appears that under the
conditions about hall the deposited gold is amal-
gamated, and that part of this passes or is driven by
the current through the mercury and adheres to the
surface of the plate.
No. 3. — A current of 0.15 ampere per square foot
was passed for ninety-two hours through solutions
containing 0.2% KCy, using the same vessels and elec-
trodes as before. Quantities of black non-adherent
gold was precipitated as before, but the proportion
between the amounts in this form and that amal-
gamated was not estimated.
No. 4. — In this experiment an amalgamated cop-
per plate, forming the cathode, was suspended in a
vertical position in 1700 c.c. of a solution containing
0.04% KCy and seven ounces gold per ton. A cur-
rent of 0.04 amperes per square foot of cathode was
passed for twelve hours. A black powder formed
slowly on the cathode, and at the end of the experi-
ment was swept off and yielded 4.5 m.m.g. of gold.
The amalgam scraped from the plate yielded 144
m.m.g., and 201 m.m.g. of gold remained in solution.
About 3% of the precipitated gold was, therefore,
deposited as a non-adherent powder.
No. 5. — Continuing in the same direction, 1500 c.c.
of a solution of 0.05% KCy and 9.25 ounces gold per
ton was subjected to the action of a current of 0.02
ampere per square foot of cathode for nineteen
hours under conditions similar to those maintained in
No. 4. The black powder again appeared on the
cathode, was removed by a feather, and proved to
contain 2.5 m.m.g. of gold. Owing to an accident,
gold in the amalgam was not estimated, though pres-
ent in considerable quantities.
No. 6. — A similar result was obtained, using a
round bath of mercury llf inches in diameter as
cathode. The current used was 0.027 ampere per
square foot, and the fall of potential 0.75 volt, the
anode being a small plate of pure gold. The weight
of black scum collected after forty-eight hours' run
was here only 1.6 m.m.g., and the amount deposited
and amalgamated 718.6 m.m.g., or 99.78% of the
total weight thrown down by the current. The solu-
tion contained 0. 14% KCy and 3% of common salt.
No. 7. — Finally a current of 0.01 ampere per
square foot was tried with arrangements similar to
those in experiments Nos. 4 and 5. The fall of po-
tential was about 0.7 volt. The solution contained
0.082% KCy and twenty ounces of gold per ton.
After a run of twenty-four hours no change could be
detected in the appearance of the cathode plate, no
black film having made its appearance, but 93 m.m.g.
of gold were recovered from the amalgam formed on
*A paper read by T. K. Rose before a recent meeting of the
Institution of Mining and Metallurgy.
the plate, an amount equal to 70% of the theoretical
quantity which the current was capable of deposit-
ing. In some further experiments with 0.004 and
0.005 ampere per square foot and very dilute solu-
tions of cyanide and gold, the cathode in every case
remained clean and unchanged in appearance.
It is clear from the results given above that, when
mercury or amalgamated copper plates are used as
cathodes in the electrolysis of gold cyanide solutions,
satisfactory precipitation can only be obtained when
a low current density is employed. With 0.01 am-
pere or less per square foot of cathode gold is pre-
cipitated and amalgamated simultaneously, the plates
keeping in good condition during twenty-four hours'
use, while i ounce of gold per square yard of plate
was deposited on them. With currents of greater
density, part of the gold is deposited as a non-adher-
ent black powder, easily rubbed off, but not easily
detachable by a jet of water, and not easily amalga-
mated. As the density of the current is increased,
the percentage of non-amalgamable gold thrown
down rises, until at 0.30 ampere per square foot
about half the precipitated gold is not amalgamated.
It, therefore, appears that one essential condition in
the use of amalgamated plates as cathodes has never
been clearly laid down.
In all the above experiments the condition of the
precipitated gold was alone in question, no attempt
being made to recover all the gold from the solutions.
Moreover, any gold driven into the interior of the
plates by the current was allowed to escape observa-
tion, but the experiments show that most of the
deposited gold was recovered, and, therefore, that
the amount could not have been so large as to pre-
clude the use of such plates. The question now arose
whether precipitation on copper plates could be
effected conveniently and completely, and the follow-
ing experiments were devised to test this :
No. 8 — Three baths, each containing 1750 c.c. of
solution, were used, the first being fitted with amal-
gamated copper electrodes ; the second having iron
anodes and lead cathodes ; the third being without
current or electrodes. The solution contained
0.0165% KCy and 0.0288 gram of gold per liter, or
about 18J dwts. per ton. The area of the cathodes
was 40 square inches, or about 162 square feet per
ton of liquid. A current of 0.0012 ampere was used,
equivalent to 0.005 ampere per square foot. After
passing the current for eighteen hours the condition
of the electrodes was as follows : Copper cathode,
clean ; copper anode, dark colored ; lead cathode,
coated with gold ; iron anode, much oxidized, but
showing no Prussian blue. The solutions were exam-
ined and found to contain the following quantities of
cyanide and gold :
(1) Copper cathode.... 0.0015% KCy, 0.0100 gram gold
per liter (or 6i dwts. per ton).
(2) Lead cathode 0.0025% KCy, 0.0215 gram gold
per liter.
(3) No electrode 0.0025% KCy, 0.0288 gram gold
per liter.
About 60% of the current had been usefully em-
ployed in bath No. 1 in depositing gold, and 23% of
the current in No. 2. Very little circulation of the
liquid was attempted, but the baths were stirred
occasionally. There had been no perceptible decom-
position of cyanide due to the passage of the current.
No. 9. — Three baths were used, each containing
700 c.c. of a solution of 0.0025% KCy and 0.0360 gram
gold per liter, or 1 ounce 3 dwts. per ton. The same
electrodes were used, giving 400 square feet of
cathode per ton of liquid, and a current of 0.0035
ampere per square foot was passed for 23J hours,
with occasional stirring. After this the appearance
of the electrodes was the same as in the last experi-
ment, and the solutions contained —
(1) Copper cathode. . .No KCy, 0.0075 gram gold per liter
(or 5 dwts. per ton.)
(2) Lead cathode 0.0010% KCy, 0.0090 gram gold per
liter (or nearly 6 dwts. per ton.)
(3) No electrodes 0.0010% KCy, 0.0360 gram gold
per liter.
The amount of current usefully employed in pre-
cipitating gold was thus about 36% in bath No. 1,
and 34% in bath No. 2. The fall of potential in the
baths was 0.22 volt at the start, and 0.6 volt at the
end of the experiment.
No. 10. — In this experiment the gold was more
completely precipitated. The same baths and elec-
trodes were used, the solutions containing 0.03% KCy
and 0.100 gram gold per liter, or 3 ounces 4J- dwts.
per ton. After passing a current of 0.005 ampere
per square foot for 4 days 16 hours, the gold in each
bath amounted to about 0.001 gram gold per liter, or
16 grains per ton. The amount of gold left in solu-
tion was tried each day by the purple of Cassius' test.
No available cyanide was left in either bath at the
end of the experiment.
In another experiment in which a current was
passed through a rich solution for 14 days, 0.828
gram gold was deposited from solution, and 0.550
gram, or 66.4% of the total amount precipitated, was
recovered from the amalgam scraped off the plate.
It is clear from these results that the decomposition
of cyanide is created when amalgamated copper
electrodes are used than if lead and iron plates are
substituted for them. On the other hand, more gold
appears to be deposited on copper than on lead,
especially when rich solutions are being treated. It
seemed certain that both these effects were due to
the chemical action of copper on the solution, work-
ing in conjunction with the current. In order to
determine whether the whole of this effect came from
the anode, or if part was attributable to the cathode,
a small current was passed through a solution of
0.06% KCy, using sheet lead anodes and an amalga-
mated copper cathode. After 24 hours it was found
that copper could be detected in the solution. The
weight of the amalgamated copper cathode was —
Before using 149.953 grams.
After using 149.881 grams.
Loss by dissolution 072 grams.
The current had therefore been unable to protect
the cathode from attack by the solutions.
The conclusions to be drawn from the experiments
do not appear to lend any countenance to the view
that mercury or amalgamated copper plates will ever
be satisfactory substances to use as cathodes in the
electrolysis of cyanide solutions. A current must be
of small density in order to deposit gold on mercury
in a form in which it can be easily recovered. Conse-
quently, as Von Gernet said, the high cost of mercury
prohibits its use. On the other hand, with amalga-
mated copper plates, the density of the currents
must be apparently even smaller, not exceeding say
0.015 ampere per square foot, in order that the gold
may be deposited and retained, and the dimensions of
the cathodes must, therefore, be even greater than
if mercury is used. Apart from the cost of the plates,
however, the cyanide solution suffers loss by dissolv-
ing copper from the cathode, and against all these
disadvantages there appears to be no real advantage
to be gained by using them instead of the customary
lead cathodes.
Ozokerite.
Written for the Mining and Scientific Press by
Dr. J. Obly.
There are only two ozokerite mines of any magni-
tude in the world, though claims of recent discoveries
in different parts of the United States have been
made from time to time. These are the Galician
mines, the oldest works of that kind known, which
are controlled in greater part by a Russian syndicate
and to a smaller extent by French capitalists ; and
the Utah deposits, which are in the hands of Ameri-
can concerns.
The mineral has also been located in Moldavia, a
northern province of Koumania, in the vicinity of coal
and rock salt, and at Gresten, near Gaming, in Aus-
tria, while it occurs besides at the Urpeth colliery,
near Newcastle-on-Tyne, Northumberland, England.
The Galician deposit is found chiefly in the Miocene
formation, a term applied to the middle division of
the Tertiary strata of the mammalian age. The
veins in which it is encountered have been traced on
the surface for a distance of 132 to 270 feet, and
measure about 3« feet in diameter. They pass down-
ward through beds of sand, from 26 to 33 feet in
depth, containing large siliceous rocks, and enter
gradually a blue clay, from which naphtha generally
oozes, when they finally disappear in a layer of plas-
tic loam. The center of the basin is richest in ozo-
kerite, and in some cases soft masses of such extent
have been tapped that the miners had hardly time to
escape before the workings were filled with the
plastic material. Such a deposit was encountered in
1893 in the deepest shaft at Boryslaw, Galicia, at a
depth of 681 feet. In general, however, the yield of
wax varies from 2% to 8% of the mineral extracted.
Originally ozokerite was discovered in Galicia by a
prospector searching for petroleum, with which
much of the ground is saturated, and was regarded
for a long time as an unwelcome associate to the oil,
since it frequently caused the timbering of the shafts
to collapse. It was only about twenty years after
its discovery in Moldavia that ozokerite began to
attain commercial importance, as a method was then
discovered for producing a substance from it known
under the name of " cerasin."
Previous to 1865 this ozokerite deposit had been
regarded as a Crown mineral, a term implying that
the Austrian government had the exclusive right of
mining and disposing of the product. But when it
was declared free in that year, a number of shafts
were sunk in the district, and much speculation en-
sued. The land being parcelled out in small plots,
numerous shafts of small section, mostly 3x4 feet,
were sunk in the immediate neighborhood of one an-
other, so that the mining of the mineral became a
difficult and expensive operation, and much of the
material was wasted.
The geological formation of the Galician deposit,
shortly indicated before, is characterized by the
presence of clay, salt and sandstone, which in con-
nection with the occurrence of petroleum, represent
the ideal conditions under which the existence of ozo-
kerite becomes probable. Broken rock strata and
saddle formations are considered furthermore as in-
dications favorable to the presence of the mineral,
judging largely from the character of the two locali-
ties in which ozokerite deposits of any magnitude
have been found.
One of the main Utah deposits is situated Ibetween

Pleasant Valley Junction and Soldiers" Summit, a
mile and a half from the Etio Grande Western, while
another lies within a distance of about 5 miles
west of this, and has been abandoned as a non-pay-
ing venture. The vein matter of the tirst named
mine is between '.'. and 4 feet wide, contains occasional
poekets or kidneys, and shows a network of small
veins permeating the fissures. The upper stratum
consists of blue limestone of varying thickness, which
overtops a sandstone formation of unknown depth,
the latter cropping out at the surface in places. The
ozokerite veins permeating this sandstone layer
have been worked down to about 150 feet, and are
expected to reach a deptb of at least five times that
distance. The mineral products obtained from this
deposit are classified as vein matter and shale, re-
spectively, samples of which were analyzed recently
in the laboratory of Field & Goody, Denver, Colorado,
with the following results:

The mineral residue, which was very small in the
vein matter, showed in each case the presence of
lime in prevailing quantities, together with iron
oxides and alumina.
The method employed in Utah for the extraction of
the ozokerite from the gangue consists in treating
the pay rock — holding in the special locality referred
to up to 20% of values — in cylindrical tanks, 6' feet in
diameter and 8 feet high, filled with water and heated
by steam through an inside coil of iron pipe. This
tank is provided with a water and oil gauge and a
number of spigots, by means of which the liquid
ozokerite is drawn off into rectangular pans, 10 feet
long by 5 feet wide and 18 inches high — also heated by
steam. Here the fluid mass is freed from mechanic-
ally enclosed water, which operation is accompanied
by much rising and frothing of the substance, when it
finally subsides and is conducted into circular molds
so as to form, on solidifying, round cakes of 16 inches
diameter, in which form it is brought on the mar-
ket.
This treatment is based on the low melting point of
ozokerite, which lies between 50° and 08° C. , and its
specific gravity, varying between 0.85 and 0.1)0, so
that it separates gradually in a fluid condition from
the gangue and floats to the top of the heated water.
The subsequent operation of driving off the water was
omitted in the beginning of the manufacture, toward
1893, so that Utah ozokerite, which, strange to say,
was then known as Colorado ozokerite in England,
obtained thereby a rather unenviable reputation.
When taken from the mine the mineral is usually of
a yellow or light brown color, which gradually dark-
ens, however, on exposure to the atmosphere. Si-
multaneously the wax hardens and becomes heavier —
circumstances which are caused by the evaporation
of volatile hydrocarbons always associated with the
substance. For these reasons it seems fair to assume
that the mineral originated from petroleum by the
limited evaporation of the lighter hydrocarbons con-
tained in it, and that the base of its formation was
this oil. The latter presumably entered the fissures
from below, and, being restrained by its enclosure
from coming in contact with the air except at the
surface, lost but a part of these volatile bodies', per-
meated the adjoining sand or lime formations to form
bituminous shale, and left the heavy hydrocarbons
behind as ozokerite. In other words, nature per-
formed a task similar to the operation carried on in
the fractional distillation of petroleum in retorts, but
resorted in her punctilious ways to the preservation
of all the values present by a tedious and gradual
process at low temperatures and peculiar condi-
tions.
It will be seen from the foregoing analyses that
ozokerite is especially valuable on account of the
paraffine wax and paraffine oil contained in it in con-
siderable quantities. To produce these compounds
advantageously the mineral should be subjected to
destructive distillation in a retort, when a volatile
gas and a burning oil come over first at 360° C, and,
on raising the heat to about 500° C, a mixture of
paraffine and paraffine oil results, which is readily
condensed in the receiver. The heating ought to be
done gradually and uniformly at a dull red heat, and
no part of the retort should be allowed to become red
hot during the operation. If these precautions are
observed, the yield is most satisfactory, and the hard,
waxy, carbonaceous residue remaining in the bottom
of the retort will be found to be in the proper condi-
tion to be manufactured into "okonite." It is incor-
porated for this purpose with indiarubber, the plastic
mixture passed through rollers at moderate temper-
ature, and the plates resulting subjected to vulcani-
zation. Having undergone these manipulations, the
product represents a very valuable insulating ma-
terial for electrical purposes and possesses, besides,
a degree of toughness and flexibility which make it a
very desirable substitute in eases where rubber alone
would not answer.
The paraffine obtained in the manner indicated
above serves partly, after proper refining described
later on, for the manufacture of candles, and is con-
sidered a superior article, since candles made from
the material arc more compact than those
prepared from petroleum paraffine, and, conse-
quently, do not bend or gutter when lighted, like the
Ordinary article. It also finds application in the
crude state for the manufacture of the finer grades
of vaseline, when the solid and liquid paraffincs pro-
duced by distillation are mixed in such proportions as
to give a material of the required consistency. The
common variety of vaseline, however, is prepared
from petroleum residues, which are melted and passed
through filters of line, granular and thoroughly dried
animal charcoal, when the resulting bleached and re-
fined product represents the article of trade com-
monly known as vaseline.
In fact, there are hardly found in nature three raw
materials more closely related than natural gas,
liquid petroleum and ozokerite or mineral wax, and
the United States excel in this regard most conspicu-
ously, since all three are found frequently in associa-
tion within its boundaries. This close relation renders
the theory acceptable that ozokerite is to be classed
with the olelines of the general formula C'„ H.,„ and
that it belongs to this group of simple hydrocarbons,
having originated by a "polymeric" change from
petroleum. This term comprises the principle ac-
cording to which a diversity of compounds can exist
under a common formula, their percentage composi-
tion being the same, while their molecular weights
and actual number of atoms differ.
Analyses of the organic elements constituting
ozokerite show it to be a compound of carbon and
hydrogen in the proportion of 85.5 and 14.5, when
pure. The natural product is, however, frequently
contaminated with admixtures of asphaltum, earthy
matter and water, so that these proportions vary to
some extent, as becomes clear from the following-
analyses :
Ozokerite from — Boryslaw. Moldavia. Urpeth.
Carbon 85.50 85.75 86.80
Hydrogen 14.50 15.15 14.06

100.86
The European mineral has been found to be
especially adapted for the manufacture of cerasin,
while the American product, when properly treated,
does not give any of the compound. This behavior is
rather startling, but cannot be doubted, since several
experimenters, and the writer himself, did not suc-
ceed in producing the substance desired from the
Utah specimens, in spite of repeated efforts. This
cerasin, which resembles beeswax in appearance and
derives its name from the Latin " Cera," meaning
wax, is prepared from the refined European ozokerite
by judicious treatment with sulphuric acid, preferably
fuming or Nordhausen acid, at a steady temperature
of 80° C, when, after the addition of all the acid
required for refining, the temperature is raised to
from 180° to 190° C, so as to eliminate all the resin-
ous admixtures present. After the removal of the
latter, the temperature is lowered to 140° C. , and the
mineral wax remaining bleached by means of animal
charcoal or the carbonaceous residue produced during
the manufacture of yellow prussiate of potash.
As the American ozokerite cannot be applied at
present to the manufacture of cerasin, no method
having as yet been devised for that purpose, its util-
ization has been limited mostly to the production of
paraffine, paraffine oil and okonite. Besides these
uses it finds, however, application in the manufacture
of varnishes, heavy lubricants, and blacking, serving
furthermore as a welcome material for caulking ships,
so that it commands a steady price in the Eastern
market. It is quoted at present in New York at 8
cents per pound for the foreign article, and at B
cents for the domestic product, transportation from
Utah to the seaboard amounting to $27 per ton.
Deducting mining and refining expenses, and cost of
transportation, there remains sufficient margin to
render the working of the deposits remunerative,
and to encourage further prospecting for the min-
eral. These favorable conditions are still enhanced
by the imminent exhaustion of the Boryslaw mines,
already reported from time to time, so that finally
the Utah deposit will represent the only source from
which to supply the market, unless new discoveries
are made in California, Utah or Colorado, for which
indications are favorable.

for years; second, two-tenths of one per cent increase
in the calculated difference between wet and dry as-
say on copper; third, a reduction of 3% on free limit

At the Paris Exposition.
From Paris A. Van der Naillen of San Francisco
writes that the mineral exhibit of the United States
is finished and open to the public and greatly appre-
ciated by the crowds before the cases filled with
specimens from mining States.
He mentions, particularly, a large piece of crystal-
lized gold of delicate leafy structure 12x8 inches,
which crowns the pyramid, loaned by J. D. Fricot of
San Andreas, Cal.
Mr. Van der Naillen says many of the leading
mines of the mineral States have contributed beauti-
ful specimens to the exhibition. Special exhibits of
quicksilver ores, bitumen rock, asphaltum, mineral
oils, borax and copper are also noticeable.
" A fine model of a 5-stamp mill in full operation,
built by the Union Iron Works, attracts great atten-
tion at all times by the hammering of the stamps."
A. Ekman of Oroville is in charge of the California
collection.
In the metallurgical department the exhibit
marked " From Quartz to Bullion" attracts atten-
tion. This interesting exhibit was donated by H. P.
Stow of the Gold Bank mine of Butte Co., Cal.
" Next to the United States comes the mineral ex-
hibit of Russia. In native gold it is far from being
equal to ours; but in all other minerals it is on a
parallel with ours. Its territory being so immense
from which to gather specimens, in its great variety
of riches of its iron ores it is superior to ours. They
have mines of pure magnetite cropping in large
ledges through the eternal snow of Lapland, and from
there to Persia and India they have mineral deposits
of all kinds.
"Italy has also an interesting mineral exhibit, the
ores mostly coming from the foot of the Alps. The
marbles are of course exceptionally beautiful.
"France and Germany are in the first ranks after
the United States and Russia. Their exhibits of ores
of the precious metals are ordinary, but those of coal,
iron, zinc, antimony and manganese are wonderful.
" The great Exposition waxes more beautiful daily
and in measure as the general sights have been real-
ized and appreciated; in the same measure do we pay
more attention to its details, and only then, when
haste is over and we take due notice of every special
exhibit, do we realize the beauty of the design, the
finish of details, the genius developed in each struc-
ture— genius harmoniously blended with art."
The Work Would Apply.
To the Editor. — Can work done running tunnel in
patented ground toward and to develop a location
made in 1899 apply on assessment work on such loca-
tion if owned by same company ? The development
work would not be of any value to the location if done
in any other way. L. W. M.
San Francisco, June 28.
Where work performed or improvements made
manifestly tend to the development of a mining claim
and made in good faith, it would be difficult to suc-
cessfully combat the case by any adverse claimant.
In the specific case mentioned the answer is "Yes."
Work done outside of a claim, if for the purpose of
developing that particular claim, and if such fact can
be clearly shown, is as available for holding the claim
as though it had been done within the boundaries of
the claim so developed.
An Act of Congress passed February 24, 1875,
amends section 2324 of the United States Revised
Statutes as follows : "So that where a person or
company has, or may run, a tunnel for the purpose
of developing a lode or lodes owned by said person or
company, the money so expended in said tunnel shall
be taken and considered as expended on said lode or
lodes," etc. .
A traveler in El Paso, Tex., might be occasioned
some trouble if he should desire to set his watch
there. Mountain time is used locally and by the Santa
Fe; central time by the Southern Pacific's Atlantic-
system and the Texas Pacific. Pacific time is
used by the Southern Pacific's Pacific system,
and the Mexican Central Mexican tame, which
is twenty-four minutes later than Mountain time.
The Southern Pacific makes a jump of two
hours, the only point where a change of more than
one hour occurs. If one travels via the Sunset route
from San Francisco to Jacksonville or Savannah on
the Atlantic he will only have to change his
watch once, at El Paso, where Pacific time is ad-
vanced two hours to Central time. There is only a
difference of two hours between San Francisco ami
Savannah.

MINING SUMMARY.
ALASKA.
The steamship San Bias, which left
Cape Nome June 21, reports that there
were forty-two vessels in Nome harbor
that day. The beach was piled high for
several miles with freight of all descrip-
tions. The sea was covered continu-
ally with myriads of barges and light-
ers transferring freight from the vessels
to the shore. Hundreds of row boats and
launches were continually passing from
the boats to the beach.
Nome beach gold is worth more than
Dawson gold. It assays $18.25 i>er ounce.
Purser Hayward says the beach claims
have been worked over three or four
times. He is of the opinion that the creeks
near Nome are rich. He thinks the popu-
lation of Nome may reach 50,000 before
the rush subsides.
Under. date of June 3, J. B. Zimdars
writes to the Dispatch from Cape Nome :
"Unless you can afford to blot out a year
of your existence and lose the cost of liv-
ing for a like period, or you can afford to
drop a thousand or more for the sake of
experience, stay at home. Under no cir-
cumstances come if you must stake your
all. It is true there is an extensive gold
belt here, reaching from Norton bay to the
Arctic. But the creeks in that belt which
contain pay are comparatively few and far
between. The beach, which is the hope of
thousands who, we are informed, are com-
ing, has been more than three-fifths ex-
hausted by last summer's work, as far as
individual mining is concerned. Some few
rich spots may yet be found, but the aver-
age beach miner will be paid with results
which will represent only average wages.
To him who cherishes the idea of finding
new creeks and becoming the owner of yet
undiscovered claims, I can but say that
virtually all that most of the people here
have so far done is to stake and locate
claims ; and if there be any creek, or gulch
or bench yet left unstaked it is a pure acci-
dent, for which the stampeder would blush
for shame should it ever be brought to his
knowledge. For men to find claims at this
late day they must bo prepared to lend
themselves to a year of hard tramping and
more wearing work than most of them
have been accustomed to, with the chances
ten to one against them. And to augment
all those difficulties there are still others
to be considered — the cost of getting here,
for passage and freight ; the almost entire
absence of food and shelter ; the shortness
. of the working season, virtually only four
months. During the eight months of win-
ter none but deep diggings and tundra
claims can be worked to any advantage,
and as far as other mining is concerned,
this period can only be devoted to prepara-
tion for the next season's run."
The Alaska Commercial Co. 's steamer
Portland from Cape Nome brought pas-
sengers and gold. The captain reports
a general and continuous row along the
beach at Cape Nome between conflicting
claim owners and their agents. There is
the usual report of considerable gold be-
ing taken out at Topkuk, and the papers
have alluring pictures of men with their
pants tucked in their boots, carrying big
bags, presumably full of gold. It is esti-
mated that there are 30,000 people at Cape
Nome. The lawyers are all busy.
The exodus to Cape Nome from Daw-
son, which has been comparatively steady,
had been superseded by the rush to the
Kyuoquot country.
The Cape Nome Gold Digger of June
13th says: " There is not a man on the
beaeh line but knows he should be pitched
incontinently, neck and heels, from his
roosting place. Each and all of the men
there have been expecting to be thrown
off and are wondering why they are not.
The value of tens of thousands of dollars
worth of proporty is involved, and the
highways and landings are obstructed.
There should be no temporizing with the
question."
ARIZONA.
GILA COUNTY.
Silver Belt: Mgr. Cutting of the Troy
mine is going to push work, commencing
soon. The company is said to have $20,-
000 on deposit in Globe for development
work.
The Ray mill, at Kelvin, will be in oper-
ation Sept. 1. The ore train is making
regular trips from the mine; there is now
on the dump at the mill a pile of ore 500
feet in length, 30 feet wide and 1" feet
high. The dump is on the upper side of
the mill and above the crushing floor.
The train runs up onto the dump and dis-
charges its cargo in a few minutes, the
cars being self-dumpers. From this dump
the ore is dropped through trapdoors to
the self-feeders over the Cornish rolls,
which are arranged in series, so that the
product from the first, or coarse-crushing
■Us, passes, automatically, to the next set
rolls, which reduce the product tu a
I greater degree of lineness and passes
it on the next set of rolls; thus the com-
mutation continues until the last set or
finishing rolls have been reached. Here
the product is caught by elevators and
carried to the top of the building, where
it is discharged, automatically, into re-
volving screens, of which there are three
sets, running in mesh from J-ineh down to
J-inch. ' These classify the pulp into uni-
form sizes, and each size is discharged,
automatically, through a chute to a dou-
ble-compartment, iron plunger jig, of
which there are twelve in the mill. These
jigs take out the coarse metal and also the
finer particles which have been freed from
the gangue in passing through the rolls,
and make clean concentrates both above
and under the screen beds. The tailings
from the jigs pass to two Chilean mills of
80-ton capacity each, where they are re-
crushed to pass through about a 40-mesh
screen and discharged onto sixteen Hallet
concentrating tables. The middlings from
these tables are pumped into an iron cyl-
inder the dimensions of which are 4x12
feet. The interior of this tube is partially
filled with Norway round flint pebbles,
ranging in size from 1 inch to 3 inches in
diameter. The cylinder revolves and the
middlings are reduced by attrition till
the pulp will pass a 60-mesh screen,
through which it is discharged and re-
turned to the tables, where it receives
final treatment. The plant will handle 250
tons of oi-e in twenty-four hours; seven
tons will be concentrated into one; the
output of concentrates every twenty-four
hours will be about thirty-five tons. The
average grade of the ore being a little
over i%, the concentrates will carry about
30% copper, beside iron and other values.
At 16 cents for coppor, the concentrates
will be worth $9G per ton for their copper
contents. The mill will require the ser-
vices of eleven men to operate it. The
company intend to increase the capacity
of the mill to 800 tons per mill day of
twenty-four hours, if the present plant
handles the ore successfully. The first
improvement made will be a railroad from
Kelvin to the S. P. or to a connection with
the Santa Fe at Phoenix.
GRAHAM COUNTY.
On June 29 the reduction works of the
Detroit Copper Co., at Morenci, caught
fire and the entire plant was consumed.
The fire was caused" by the bursting of a
slag pot. There were no water facilities.
The works consisted of a 150-ton con-
centrator, smelter furnaces and convert-
ers. The company has a 000-ton concen-
trator mill one mile distant from the old
plant.
MOJAVE COUNTY.
Mineral Wealth considers the strike on
the Juno at a depth of 400 feet important
for the district. The property was a rich
producer until tho development reached a
break in the vein that contained mineral
country rock, mud, etc., when it became
too low grade to ship. The present own-
ers have been sinking to get through this
mixed zone and have succeeded. Breaks
occur in nearly all the mines of the county
and usually work has stopped at the break
line. The Juno is the first mine in the
county to get below the break line and the
renewal of the ore is important.
North of Chloride J. C. Stewart has lo-
cated what he considers to be a turquoise
mine, worked in former days by the
Aztecs.
Near Chloride, Mgr. Wulsteinis sinking
on the Silver Age mine 3 feet a day.
The Juno mine shaft is down 400 feet,
and at the Blue Pea, Mgr. Rochford will

Supt. Gross has samples of ore from the
(330 level that, he says, will assay $107 per
ton, and other levels that will go $60.
Supt. Stewart of the Butte Basin Gravel
Co. has gravel in the long tunnel that will
average $4 per ton. At Amador work
is under contemplation at the Fremont
and Gover mines. The new shaft at the
Fremont is down over 300 feet. The old
Gover shaft will be unwatered and retim-
bered, and equidistant from the two
shafts, which are 1200 feet apart, a 60-
stamp mill will be built. In the Amador
Queen No. 1, at Jackson, Supt. Dye is
fitting up additional stamps and concen-
trators and at the 500 level is making
preparations for stoping. The ore yields
6% in sulphurets.

tank at the track in the Kern river fields,
to be used as a reservoir for lueomotive
fuel.
At Bakersfield the Hercules Oil Co. will
build an oil refinery, capacity 1000 barrels
daily.
The Californian hears that tho security
of those whose titles rest on mineral loca-
tions may be only fancied. The " scrip-
pers " have been maintaining a regular
bureau of information at Washington and
have left no work undone which would
strengthen their side of the case, while
the mineral locators, regardless of warn-
ings, have done practically nothing. The
fate of the lands depends upon the atti-
tude of the Land Department, of which
the Secretary of4he Interior is the head,
and his position is thought to be indicated
by the stand he took in relation to the
petroleum miners' bill, which failed of
passage because of his opposition.
The Kern Oil Co. has sold to Collins &
Waterman the west half of the southwest
quarter of section 4, 29-28, for $120,000, or

SILVER BOW COUNTY'.
The Parrot S. & C. M. Co., a branch of
the Amalgamated Co., has brought an ac-
tion against Heinze Bros, and the Mon-
tana Ore Purchasing Co. to have the de-
fendants perpetually enjoined from alleged
encroachment on the ore bodies of the Ad-
venture lode mining claim, of which prop-
erty the plaintiff says it is the owner. In the
complaint the Parrot Co. alleges that the
defendants have entered the alleged vein
of the Adventure from the 1100-foot level
of the Nipper claim and are engaged in
extracting ore from it.
The Butte correspondent of the Spokes-
man-Review says: The eight-hour propo-
sition continues to be the absorbing topic.
So far no word has been received from the
Amalgamated Copper Co. It remains to
be seen what Daniel McDonald, president
of the Western Labor Union, will do. The
Butte Miners' Union adopted resolutions
to continue the struggle until every mine
in Silver Bow county is worked on that
basis. It was reported that C. S. Batter-
man and F. Klepetko, general manager
Amalgamated Co., consulted Foreman
Williams and Shift Boss Dunshee of the
Pennsylvania as to the eight-hour move-
ment. They were asked by the officials if
they thought they could get as much
work out of the men in eight hours as in
ten. Both shift boss and foreman were
willing to guarantee that they could. Mr.
Klepetko was of the same opinion, but
Mr. Batterman thought that a change was
unnecessary, as ten hours was a working
day anywhere. It was rumored last week
that Supt. J. O'Neill of the Anaconda
properties had notified the committee
from the union that his mines could not
grant their request for an eight-hour day.
It was thought that a refusal of the Amal-
gamated Co. would result in a clash, and
in the end it is believed the union will win,
for Butte is essentially a union town. The
agitation will extend to all the important
mining towns of the State. Wages are 20%
higher in Butte than in other places. If a
strike is ordered, the union will not be
bucking Marcus Daly alone, but the Stand-
ard Oil Co.
The Parrot S. & C. Co. wants F. Au-
gust Heinze enjoined from trespassing or
carrying on mining operations on the
1100-foot level of the Nipper. The Parrot
Co. claims title to the ore bodies on that
level because they are alleged to apex in
the surface boundaries of the Adventurer
claim, belonging to the plaintiff. It is
alleged that Heinze has unlawfully en-
tered it and is mining and extracting ore.

tions 4 miles down the wash.
JUAB COUNTY.
At Eureka the Eureka Hill mill is oper-
ating forty-five stamps. The number is to
be increased to sixty.
Miner: D. B. Gillies has completed the
survey for the aerial tramway which within
two months will be in active operation be-
tween the Mammoth mine and mill. It
will be similar to the one in use at the
Centennial-Eureka, but with a carrying
capacity of 800 pounds to each bucket, and
250 tons per day. The distance from the
mine to the mill is 4800 feet, the difference
in elevation being 350 feet. The structural
part will be of iron and work will begin at
once on the surface. The estimated cost
of the work is $15,000; but it will affect a
great saving to the company, as it will
enable them to handle the entire output
of the mine at a cost of 6 cents per ton.
The present cost is 30 cents over the rail-
way. The tram will also carry everything
up to the mine, excepting timbers. An
iron chute will be built from the mill to
the railroad track below and the shipping
ores dumped directly into the cars.

CARBON COUNTY.
(Special Correspondence). — Battle Lake
copper district is about 50 miles south of
Rawlins : formation quartzite, schist,
diorite and red granite. No systematic
mining was done until 1898, when a plant
was obtained and several cars of copper
ore averaging 40% copper were shipped.
The mine was closed during the winter of
1898 and 1899. During the summer of 1899
work was resumed for two months, during
which time about 150 tons of high grade
copper were taken out. There are large
bodies of low grade that, owing to the
cost of transportation, cannot be worked
to advantage. The ore is in shoots in the
quartzite, though with depth it may go to
the contact between the quartzite and
diorite on the south side of the claim.
This group is on the north side of Battle
Lake and is owned by the Battle Lake C.
Co., controlled by George F. Doane, Con-
gressman Sibley of Pennsylvania and asso-
ciates. It has not been pushed. The de-
velopments consist of a shaft 265 feet, a
tunnel and good plant.
On the Hercules claim, one mile east of
Battle Lake, the owners have sunk a shaft
in a belt of diorite, the south contact of
which is red granite, the north quartzite.
At 150 feet a crosscut was run to the
granite, but onlj decomposed and oxidized
iron found. A crosscut run to the quartz-
ite found three stringers of ore aggregat-
ing 9 feet, and running about 20% copper
and some gold, and new plant of machin-
ery has been ordered, and this property is
to be thoroughly developed.
The Battle C. Co., to the west of the
Hercules, has the same formation and a
shaft down 125 feet. This property is
known as the Ledbetter property, the
present manager and original locator being
W. C. Ledbetter.
The Ferris-Haggarty mine, 4 miles
northwest of Battle Lake, on the north
fork of Battle Creek, was opened in Sep-
tember, 1898, since which time it has
shipped over 4000 tons of copper ore, 30%
copper. The ore lies in shoots on a contact
between the quartzite and schist. The
development consists of a shaft 3£x7 feet,
80 feet from which 1100 tons of ore was
taken that averaged better than 30% ; a
shaft 4Jx9 feet, 185 feet deep, which is now
being sunk deeper, a good 6x8 hoister, a
40 and 60 H. P. boiler, pumps and air com-
pressor, etc. The mine is owned by the
Ferris-Haggarty Co., and has been poorly
managed. The ore is hauled 60 miles to
the U. P. Ry. and loaded at Walcott sta-
tion, most of it going to the Chicago Cop-
per Refining Co., the Argo, Denver, and
other places.

BRITISH COLUMBIA.
Tho B. C. mine, Summit camp, has in-
creased its force to eighty-five men.
From January 1 to June 5 the Le Roi
shipped 28,609 tons copper ore, the War
Eagle 10,603 tons, the Center Star "071,
the Van Anda 2958, the Iron Mask 1434 and
tho Lonora, Mt. Sicker, Vancouver Island,
1200 tons.
Tho Trail smelter management has a
contract with the Enterprise Co. to treat
the output of tho mine. The Ymir mine
will ship to Trail; from the Queen Bess 1000
tons are to be sent via Alamo.
R. C. Pollett at Ymir has bought the
El Dorado group, on the north fork of
Porcupine creek.
Of the Poorman mine E. R. Woakes
says within a short time it will be pro-
ducing monthly ore to the value of
$22,500. He estimates that the required
machinery would cost about $50,000. It
would be advisable to renew a good deal
of the old machinery. "From the Poor-
man mine I believe we can expect a mini-
mum extraction by amalgamation of $10
per ton, with a further $5 per ton should
the cyanide treatment prove satisfactory.
The cost per ton should not exceed — min-
ing $4, milling and hauling $1.20, cyanide
$2, total $7.20."
Under date of June 30, Rossland reports
that shipments for tho past week were 4165
tons, all of which came from the Le Roi.
The shipments for the six months of 1900
were 72,080 tons.
Men are grading the railroad to the ore
bins of the Josie and No. 1 mines, now
called Le Roi No. 2.
At Kaslo the Ruth mines have bonded
the Mascot claim in the Slocan for $30,-
000.
The Payne and Slocan Star are export-
ers to the U. S. smelters. The total ship-
ments from January to June 25 were 5118
tons of ore. . ■
The City of Paris at Boundary has sent
a car of galena to be treated in the lead
stack at Trail, one of the first shipments
of such ore out of the district.
At Ymir, the Ymir mine is running
sixty of the eighty stamps. The tunnel is
being run to tap the vein at the 1000-foot
level.

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co.'s Scien-
tific Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Apparatus for Plastering Col-
umns OR THE LIKE.— No. 651,957. June
19, 1900. J. R. Tobin, San Francisco, Cal,
This invention relates to a device which is
designed for use in plastering columns,
pilasters and similar surfaces for the pur-
pose of making the plastered surface of an
equal thickness, and to maintain an equal
diameter and outline of the cylinder or
other column after it has been finished.
It consists of a bar which acts as a sur-
facer for the body of the column and re-
movable and replacable guide rings for
the upper and lower ends of the bar, said
rings forming a gauge for the plaster, and
each formed of a plurality of segments
hinged together at one end so that they
may be opened and closed to detachably
fit the column, and means for detachably
uniting the free ends of the segments.
Index for Mechanical Account
Apparatus.— No. 652,411. Dated June
26, 1900. A. W. Thierkoff, Redding, Cal.
This invention relates to a means for in-
dexing and finding accounts which are
carried upon a mechanical drum or like
apparatus. It consists in the combination
with a rotatable carrier of bills, of tabular
surfaces adapted to receive the bills or
accounts and expose them for inspection,
an index to correspond with said accounts,
a lever movable with relation to the index
and a stop moved in unison with said
lever, a series of projections or bumpers
carried by the account drum and arranged
out of direct alignment with each other,
whereby the stop is caused to arrest the
drum and a lever movable with relation to
the index and accounts.
Screw Holder and Driver. — No.
651,949. June 19, 1900. T. R. Lillie, Lodi,
Cal. The object of this invention is to
provide a device for holding and starting
screws and afterwards turning them into
position. It consists of arms having jaws
at one end adapted to clasp the head and
shank of a screw, said arms first diverg-

'.ng from the jaws, and afterwards con-
verging, having their opposite ends ful-
crumed to a transverse bar having a cen-
tral hole through which the shank of the
screwdriver is freely slidable; a second
bar intermediate between the fulcrum bar
and the jaws having closed slots in its ends
fitting and slidable upon the inclined arms
of the holding jaws, a spring interposed
between the bars and acting to normally
separate the bars and close the jaws to-
gether, arms fixed upon the intermediate
bar extending beyond the holding jaws so
as to contact with the surface into which
the screw is being driven, and thus force
the slidable arm back so that the jaws are
opened to allow the point of the driver to
advance through them and complete the
seating of the screw.
Winding Drum Indicator. — No.
652,546. Dated June 26, 1900. W. F.
Murray, San Francisco, Cal. This inven-
tion relates to a means for applying an in-
dicator to winding drums of that class in
which the drum is turnable upon a shaft
and to which power is applied from the
shaft by means of a friction clutch, so
that the operator can know accurately at
all times how much rope has been paid
out or wound up, in order to know where
the cage may be, especially when used in
deep mines. It consists of a drum loosely
revoluble upon the driving shaft, a Mo-
tional device, one member of which is
fixed to and revoluble with the shaft and
the other member carried by the drum,
mechanism for engaging and disengaging
the clutch devices, a transmitting gear
adapted to engage with the drum or a
driven part and to transmit motion to an
indicator arm, and a space dial over which
the indicator is moved in unison with the
movements of the drum.
Mail Box Time Indicator. — No.
652,549. Dated June 26, 1900. M. S. Nor-
ton, San Francisco, Cal. Assigned to the
Postal Device and Improvement Co. of the
same place. The object of this invention
is to provide a mechanically movable de-
vice and means by which information is
exposed through the front of the appara-
tus to indicate the times when mails are col-
lected, the outgoing mail with which such
collections will connect, and other matter
necessary or useful for the depositor to
know. It comprises a centrally pivoted
disk carrying the hours of collection, an
opening through the case through which
the different hours are exposed, means for
automatically returning the disk at the
end of each week day's collection, and an
automatic mechanism whereby the collec-
tions of Sundays or other days different
from those of the week day are also indi-
cated, together with means whereby the
indicator is always returned to the starting
point in readiness for the following day's
collections.
Excavators. — No. 652,395. Dated
June 26, 1900. I. P. Lambing, Denver,
Colo. This apparatus is designed for ex-
cavating and moving earth or like mate-
rial. It consists of revolubly journaled
buckets with closed ends and a scroll-
shaped periphery, the curvature of which
increases outwardly from the periphery
of the bucket through the cutting edges
carried upon the exterior of the scroll.
The buckets are so journaled that when
reversed the outward cutting edges are
presented downwardly, so that when ro-
tated through the material to be excavated
they cut out a sufficient portion to fill the
bucket, and as they approach each other
these cutting edges are turned upwardly
so as to lie side by side in parallel vertical
planes without intersecting. By means of
circular pulleys and ropes or chains they
are rotated to open and fill themselves.
The ropes or chains are connected with a
vertically slidable piston movable in a cyl-
inder mounted upon a base plate and op-
erated by. any. medium under pressure by
which the piston is reciprocated to actuate
the. buckets. .

Gold, Silver, Lead and Copper Ores.
We build furnaces to drawings and specifications, and furnish drawings and full Instructions for ereotlng.
We ereot all furnaces at our works and oarefully mark every pleoe before shipping. By this means, trouble In erecting at
the smelting plant Is entirely avoided.
We contract to build and equip smelting plants complete, of any required tonnage capaoity above forty tons per day, at
any desired locution and put them into successful operation under guarantee. We contraot to smelt a thousand tons of ore, more
or less, before turning the plant over as completed under the guarantee
We have in the past built more Blast Furnaoes for smelting the ores of the valuable and the precious metals— gold, silver,
lead and copper— than any other manufacturing concern on the American oontlnent, and in the past year of 1890 we built more
suoh furnaces than all others combined.

SPADONE'S CONCENTRATOR BELTS.
PATENTED.
This illustration snows the edge flanging out-
wardly as It passes over the pulley. This re-
lieves the strain from the top and bottom of the
edge by directing the strain automatically to
the inside face surface of the edges. Hereto-
fore all belts have been so constructed that
when they pass over the pulleys or rolls, a di-
rect strain comes upon the top or at the base of
of the edges, causing the edges to break away
from the body of the belts in a very short time.
We avoid this Mechanical Defect by our Spadone
Curved Edge. Belts made to fit any machine—
4, 5 and 6 feet wide. Prices and samples on ap-
plication.
AMALGAM PLATE CLEANERS.
Our Amalgam Plate Cleaners are made of Pure Rubber in moulds, thus insuring a plate cleaner
which will not scratch the plates and a perfect edge which will clean the Amalgam plates evenly.
They are made 6 inches long, 3 inches wide and % inch thick, making a convenient size to handle.
Price by mall to any address, each 75 cents. Correspondence solicited.

Infringements will be prosecuted to the fall extent of the law.
PRICE, $450, F\C>. B.f San Francisco.
Some Practical Reason* Why the Wtijlev Concentrator Should Be Uaed <n
Gold Mills:
It will successfully handle three or four times more material
than any belt Concentrator made, without exception.
It will Bave more Bulphurets In proportion while so doing, and
catch any float rold, amalgam or quicksilver which may escape
from mortars or plates.
It will make cleaner and much more valuable concentrates, thus
savin? useless expense for transporting valueless material, a&
also extra cost for treatment.
It requires little or no attention when once adjusted and no ex-
pert Is required to either adjust or run the machine.
It will Bave much expense in power and room, and the first coat
of a mill requiring- concentrators.
It Ikih no expensive belts to crack and wear out, nor complicated
machinery to keep in repair.
It is the only sensible plan of concentration, as any kind of mate-
rial can be worked, which Is not true of any style of belt ma-
chine.

The Ideal Conveyor Belt
Mining and Scientific Press
23
Is the one that will carry atone, ore, coal, wet or dry
material, holding buckets tlrmly and securely; will
stand all kinds of exposure, and resist the heaviest
strains during a long period of service. This Is what
the LEVIATHAN UELT has done, and we quote the
following from a letter from the New York Steam Co. :
" We havo used Leviathan Belting for four years, up
to 2-J-inch by 8-ply. elevating and conveying coal. Some
of the Belting Is outside, exposed to freezing weathor;
some in a steam bath. In both conditions the results
havo been very gratifying, over 50U tons having been
handled in ten hours time."

The Ideal Conveyor Belt
Is Che one that will carry atone, ore, coal, wet or dry
material, holding buckets tlrmly and securely; will
stand ull kinds of exposure, and resist the heaviest
strains during a long period of service. This is what
the LEVIATHAN BELT has done, and we quote the
following from a letter from the New York Steam Co. :
" We havo used Leviathan Belting for four years, up
to 24- inch by 8-ply, elevating and conveying coal. Some
of the Belting is outside, exposed to freezing weather;
some in a steam bath. In both conditions the results
have been very gratifying, over 600 tons having been
handled in ten hours time."

The TREMAIN STEAM STAMP MILL

A Money Maker in Nicaragua.
GATES IRON WORKS, CHICAGO.— GENTLEMEN:
MURRA GOLD MINING COMPANY, NICARAGUA,
Nicaragua, June 20, 18t
After an experience covering a period of three years with both the first and improved " Tremain Steam Stamp Mill," in every par-
ticular I have found it perfection— a money maker, and just the thing for a small oapital, while companies organized on a large soale
would do well to look into Us merits.
I find no difficulty in crushing eight tons of ore per day and running on hard ore. This mill should be a winner.
Very truly yours,

GOLDEN P. O., JOSEPHINE CO., COLO., Deoember 23, 1899
GATES IRON WORKS, CHIC AGO.— Gentlemen :
Our Tremain Mill is giving us good results, and although being in operation since 1892 has not cost us $1 for repairs, and to-day is
making 180 drops per minute with 95 lbs. steam pressure.
The ore we are working at present is soft and we mill in 24 hours, using No. 10 slot screen, 15 tons.
Yours truly,
M. C. DAVIS,
Superintendent Sarah Belle Mines.
Running Under Compressed Air in West Australia.
293 ST. GEORGE'S TERRACE, PERTH, W. A., February 6, 1900.
F. R. PERROT, ESQ , Agent of Gates Iron Works, Perth, West Australia.
Dear Sir: In reply to your enquiry as to the working of the Tremain Mill on the Burbanks Grand Junction, I would state
that at the start we worked this from the boiler supplied by the Gates Iron Works Company, but owing to certain irregularities of
the running, which were in a measure due to the intermittent supply of ore and the short time that we were able to run it per
day, I finally laid on air piping from my air compressor, a quarter of a mile distant, and used the boiler as an air receiver
with the result that I got an absolutely constant run, which, I believe, averaged about 105 drops per minute, and this was kept up
with great regularity and showed a much better return in the treatment of the ore. The usual air pressure in this case was 80 lbs
whereas under steam we were not so satisfied with the result as worked at 100 lbs. By this we were also saved in cost the charges of
stoker, fuel and water, and it was worked with muoh greater cleanliness, and during the whole time the mill was running which was
several months— it never froze up on us or showed any signs of trouble in that direction.
The mill is now temporarily stopped, but when it Is again started I shall most decidedly continue the use of compressed air
Yours faithfully,
[SIGNED] GEO. HEWER.

" Empire, Colo. : The success achieved by the Cammett

pecially difficult to concentrate on account of the great
variety of its metallic contents, has given the Bonaccord mill
a reputation that will firmly establish it as a safe plant for general

THE GRIFFIN
THREE ROLLER
7VYI
Tho Griffin Threo Roller Ore Mill is a simp.y constructed Mill, suitable for working all kinds of ores that
require uniformly fine crushing by the wet process. This Mill is a modification of the well-known Chilian
Mill, but the rollers run upon a crushing ring or die, which is inclined inwardly at an angle of about 30 degrees,
the rollors themselves also being inclined to the central shaft of the Mill, thus utilizing the centrifugal force,
as well as the weight of the rollers thomselvos as a crushing agent. The Griffin Three Roller Ore Mill is there-
fore a Mill of great strength, and has few wearing parts. We construct these Mills with extreme care, using
only the best of raw materials, which are most carefully worked by men who are specialists as mill builders.
We sell the Griffin Ore Mill on its determined merits, and will gladly supply full information regarding it to
any one.

High Explosives.
In the three preceding issues of this paper have
appeared technical articles on dynamites and their
manufacture, details of the make-up and method of
application of the principal high explosives in present
use. In the current number of the International
Monthly appears an article on the same general sub-
ject by Capt. E. L. Zaliuski, whose "dynamite gun"
attracted some attention two years ago in the
American squadron's practice off the Cuban coast. A I
mont is made of a new high explosive, insensitive and
powerful, with secret ingredients, one is likely to be
correct in the assumption that it is of the Sprengel
group. Among the better known of these are :
Rack-a-rock — Chlorate of potash and a liquid hydro-
carbon (dead oil). Two hundred and fifty thousand
pounds of this explosive were used in blasting out
Hell Gate. Bellite — ammonium nitrate, nitro-ben-
zole and saltpetre. Roburite — ammonium nitrate
with chlorinated di-nitro benzole. Helloflte — naph-
thalene, phenol or benzine in fuming nitric acid.
In the opinion of Capt. Zalinski the picric acid class
of explosives deserves attention, more because of
public notoriety than of intrinsic merit. Among
these are melinite, for which the French have claimed
so much, and lyddite, used by the English in the
South African war. These are both essentially the
same, consisting chiefly of picric acid combined with
nitro-cellulose, and in some cases with cresilite.
The relative power of explosives is difficult to esti-
mate, and authorities differ regarding it, for there is
a notable difference in the results obtainable, depend-

condensation of Capt. Zalinski's article may serve-as
a fitting conclusion to what has already appeared
herein concerning this subject.
He considers that the touchstone of experience has
eliminated from practical use most of the explosives
which have recently been presented in such large
numbers, there being now left, as the chief explosives
in use, nitro-glycerine, gun cotton, dynamites con-
sisting of nitro-glycerine combined in various propor-
tions with various bases ; -blasting gelatine ; explo-
sive gelatines and gelatine dynamites consisting of
various combinations of nitro-glycerine and gun cot-
ton, with a mixture of saltpetre, cellulose and soda.
Besides these are the Sprengel group of explosives.
This consists of two practically inert substances,
which, upon being mixed, produce powerful explo-
sives,. One of these substances is usually a hydro-
carbon. An almost infinite variety of explosives of
this class has been produced. "Whenever an announce-
Securite — meta di-nitro benzole with nitrate of am-
monia or saltpetre.
The composition of a sufficient number of this class
of explosives has been given, to indicate the variety of
constituents which can be used in making high explo-
sives of this group. They are all insensitive and re-
quire a very powerful initial explosion to educe their
full power. Those having nitrate of ammonium are
likely to be objectionable and not of advantage, in sub-
marine work and places where water is present, ow-
ing to the hygroscopic quality of that salt, which
tends to deliquesce, unless well protected from mois-
ture. Two recent explosives, of secret composition,
which have been much vaunted, marsite and thorite,
probably belong to this class. It is thought that the
latter may be usefully employed for the torpedo shell,
but it is as yet a question whether it can be com-
pletely exploded when in large charges, so as to give
an explosion of the first order.
ing on the physical conditions attendant upon the
placement of the explosive and the means and method
of the initial explosion. Some confinement or tamping
is essential ; the difference in the results secured be-
tween an explosion in the open and when covered,
however slightly, is very great, and should be borne
in mind by those using explosives for industrial pur-
poses. The same amount or degree of tamping is not
as necessary for the high explosives as for gunpow-
der, and much needless and dangerous work might be
avoided if due consideration were given to this point
of difference. According to the best authorities, the
following table is given as showing the, relative force
of the various high explosives, submarine work ex-
cepted, gunpowder being taken as one :
Gunpowder, 1; dynamite No. 1, 10; gun cotton 5.5;
bellite (Sprengel), 6; nitro-glycerine, 12,; roburite
(Sprengel), 3; explosive gelatine, 14; melinite, 3;
blasting gelatine, 16; lyddite, 3.

saying that he is "a scientist and not a charlatan,"
that he is studying certain forms of disease from de-
cay, and hopes later on to have some results of pos-
sible value, which is about what a true scientist
would say. Men who really do something — Bessemer,
Thompson, Edison and such as they — first made sure
that what they gave out was accurate, and never
indulged in fanciful prophecies in flash journals, nor
announced what they were " going" to do.
Present conditions in the Witwatersrand, South
Africa, mining district illustrate forcibly the ad-
vantage of a mining investment as a permanent prop-
osition. Though the storm of war has swept the
surface of the Rand the mines themselves are intact.
The value of the ore therein can not be destroyed by
fire or water, nor any destruction wreaked by re-
venge. Of no other industry can this be said. Any
other form of industrial life would have been annihi-
lated by the warfare of the past few months there ; but
in sixty days after the cessation of hostilities the Johan-
nesburg mines will be turning out gold profitably as
heretofore. Nor is there any depreciation in the
price of the product in the markets of the world, nor
do the producers have to seek customers, for
coined or in bullion the refined product is worth $20.67
per ounce the world over. Of no other industry can
these things be truthfully said.
It was noted herein some months ago that while in
the nature of the case mining precluded the forma-
tion of "trusts" in their present meaning, yet the
tendency in mine management is to follow the exam-
ple of the trusts in observance of the intents and
purposes that characterized their initial movements,
viz : consolidation, because of economy of operation.
Since then several mines in Cripple Creek district,
Colo., the Mercur and Golden Gate properties in
Utah, two in South Dakota and two in Idaho have
consolidated with economic intent, and now from
southern Nevada is report of similar negotiations by
the April Fool and DeLamar. Such is the tendency
of the times. In connection therewith it is to be noted
that in such consolidation lies partial solution of the
problems of "apexes" and " extralateral rights."
It were vastly easier for two contiguous properties
to consolidate than to fight over incursions into each
other's property, besides the saving occasioned by
such action.
Sensational " scientific " announcements in.Sun-
day papers and popular magazines serve a good pur-
pose as light summer reading, but are not to be taken
seriously. N. Tesla is usually good for a column of
alleged statement of fact, his latest being announce-
ment that aluminum will so supersede copper as to
render the red metal of secondary value. P. Metch-
nikoff, of the Pasteur Institute, is credited with dis-
covery of "a series of lymphs," which, properly in-
troduced into the human body, will ' ' check decay
and indefinitely prolong life." M. Metchnikoff nat-
urally denies and dislikes such statement, modestly
The Telephone in Business.
Recent mention of the Western Union Telegraph
Co.'s intent to apply twenty million dollars to active
competition in long distance telephone service illus-
trates how that device is entering into intimate com-
mercial life, and how it is eating into the business of
the telegraph company. It is equally noticeable how
telephony has cut into the business of the railroads.
Railway managers say that since the introduction of
long distance telephone systems travel is much
lighter. This is evident. It is vastly easier for a San
Francisco man to talk to a Los Angeles correspond-
ent, or a Chicago man to a New York resident, than
to travel between the two cities, and to all intents
and purposes a talk over a long distance, telephone
has all the practical points of a private, personal in-
terview at much less cost and with equally satisfac-
tory results.
The great advantage of the telephone over any
other means of communication is that one is in direct
communication with his correspondent, that his mes-
sage is replied to on the spot, that there can be no
reason for mistakes, no misunderstanding of the mes-
sage; that each party to the interview knows at once
what the other says, clearly and fully, and that with-
out leaving one's own home or office he can have all
the advantage of an immediate personal talk without
the expense or annoyance of travel or the delay inci-
dental to letters or even telegrams. Great as is the
increase in the telephone service it is probable that
it will extend still more ; for despite its drawbacks
and incidental annoyance, its advantages so out-
weigh those that it is universally recognized as an
economical business proposition. More especially
does it cater to the wants and tastes of the American
people who always would fain do two days' work in
one and compress the affairs of a day into an hour.
This is the great claim of the telephone, that it
makes it possible to do in one minute what before
took an hour ; or in five minutes what used to require
an entire day. It enlarges the volume of business,
shortens the time, and lessens the labor of its trans-
action.
The scientific importance of the telephone has long
been distanced by its practical commercial applica-
tion. Men who by reason of their position should
know what they are talking about claim that it is
possible to establish telephonic communication with
Europe, for, while there is too great resistance to
successfully operate a direct telephone cable across
the Atlantic, it is claimed that by a longer route,
with landings at the different islands, it will be en-
tirely feasible to construct an international telephone
line that would give good practical results. At pres-
ent toll line conversations in this country are held
over distances of 2000 miles ; as, for instance, San
Diego, California, to Boise, Idaho. Like all other
great enterprises, only more especially in this case,
the tendency of telephone management is toward
monopoly and exclusive control, and it is probable
that the result of present combinations and consolida-
tions and pooling of issues will be the operation and
control of the telephone service of the entire country
under one general management.
The profits of the service are enormous. With the
exception of transportation to Alaska, there is prob-
ably no money invested in any enterprise that pro-
duces such great and immediate return in per cent of
profits as that invested in telephones, and paradoxi-
cal as it may seem, that very fact, which would ordi-
narily invite competition, will tend more than any-
thing else to demoralize opposition and result in a
close monopoly.
Like other forms of electrical appliance, telephony
is a progressive science. The latest development is
the telephonograph, devised by M. Paulsen, Leipzig,
Germany. It is described as "a combination of a
telephone and a phonograph for the purpose of re-
cording messages received during the absence of the
operator. The person called up has only to hold the
trumpet to his ear upon returning to the office,
even after an absence of days, to receive the
message. Many inventors have tried to effect
sucha combination, but all failed on account of
the difficulty of transferring the message onto a
wax cylinder."
Instead of a wax cylinder, Paulsen uses a flexible
steel band in his phonograph, messages being more
easily removed from the steel band than from the
wax cylinder. The band is wound on two spools,
moving quickly from one to the other, coming in con-
tact with a very small electro-magnet, switched into
the circuit, which affects the steel band in such a way
as to record on it any sounds that may penetrate to
the phonograph. The inventor says: "It is only
necessary to cause the steel band to repass the mag-
net in order to have the sounds repeated. Each
vibration of the electro-magnet produces a corre-
sponding vibration of the steel band. In order to
remove a message from the steel band, a magnet is
passed over the surface on which the message was
recorded."
An Advance in Silver.
The silver market has improved since the close of
the fiscal year and an upward movement is noted.
Two causes contribute to this, the first being the de-
mand from the Indian Government, owing to an in-
crease in coinage, and in China the present troublous
conditions in that country have stimulated the ex-
port trade and diminished the imports. Present
hostilities in the latter country have caused some
hoarding and have restricted the selling of European
wares. The Chinese banks have consequently found
themselves called upon for larger quantities of silver
than usual. The second cause of the advance arising
from this must be credited to the smelting trust.
The American Smelting & Refining Co. keeps silver
bullion off a weak or failing market, and in the case
cited the demand was exploited by the utmost pos-
sible advance in price.
As noted in last week's issue, Russia also ap-
pears in the market. Silver is now being
shipped to Port Arthur in considerable quan-
tities— apparently to the Russo-Chinese bank, a sort
of political institution. The Russians are probably
desirous of accumulation of a big military chest with
the kind of money in it that the Orient wants. In
connection with this whole matter, it is also to be
noticed that, in the shipment of gold, that metal
comes back; but in the shipment of silver to the
Orient, it is absorbed. India, China and now Russia
constitute sinks of silver, and to the demand from
these three countries may be ascribed its recent rise
in value.
Heartily Appreciated.
With cordial appreciation is noted numerous kindly
references to this paper in the columns of its con-
temporaries. In these days of numerous publications
any journal can count itself fortunate to be able to
secure favorable notice among its fellows, and be-
cause of this we feel it all the more complimentary
that such praise is accorded this paper in so many
friendly columns. It will be our endeavor to deserve
it. To reproduce the hundreds of editorial expres-
sions of good will and esteem would take up about all
the space in one issue. The Denver Daily Post be-
gins an article that would take over a column of our
space this way:
The Mining and Scientific Press of San Fran-
cisco closed its eightieth volume June 30th. It is not
extravagant to say that for the miners of the West —
gold, silver, copper, coal and iron — it is the best
newspaper of its class in the English language.
In a three-quarter column article the Denver Min-
ing Reporter says:
The Mining and Scientific Press is the best
chamber of commerce San Francisco ever had. Its
story is told weekly to thousands of people who
never heard if there be such a thing in San Francisco
as a chamber of commerce.
These are samples of what is said about this paper
by many competent critics in kindly confirmation of
the facts, and we may be pardoned for an ex-
pression of pleasure therein.

Concentrates.
A "KNOT " is a nautical mile, and is equal to 6080.27
feet, or 1.15156 statute miles.
Fluor SPAR is worth $5 or SB per ton, delivered to
iron smelters. There is little demand for it west of the
Rookies.
Gold and silver dissolve at nearly the same rate, atom

potassium cyanide.
Ckrite is an ore found in Sweden, containing silicates
and oxides of cerium, didymium and lauthanum, and is
imported free of duty.
The Stevens process is essentially a chloro-bromo pro-
cess, and if successful anywhere the fact has as success-
fully eluded general observation.
The only substance which will act as a screen for mag-
netism is iron. Surround a space with a thick shield of
iron and magnetism cannot penetrate it.
The lighted candle test for foul air is not a safe one.
Gas destructive to human life, yet permitting a candle to
remain lighted, may exist in underground workings.
In the case of corrosive mino waters, iron or lead pipe
are usually unavailable unless lined with j-inch pine.
Bronze is probably the best material to use in such cases.
There is little use for selenium except in electrical
use, and even in that only to a very limited extent. It is
not a United States production, but is imported from
Germany.
Platinum has been found in the sands of the Yukon
creeks, but there is no record of the amount saved. The
account of the richness of those sands in platinum is
doubtless exaggerated.
Diamonds of fair size and considerable value have
been found in Butte and El Dorado counties, Cal., but no
systematic or continued effort to determine their source
has been put in practice.
Celestine is not found west of the Rockies. It is
sulphate of strontium, is somewhat like barytes, and is
used for making red fire and in beet sugar refining. It
is worth about $3 per ton.
A steam engine, the cylinder of which is 2x4 inches,
at sixty pounds boiler pressure, and with 150 revolutions
per minute, would develop about 5 H. P., and would need
a boiler having 10 square feet of fire heating surface.
A ton of coal — 2000 pounds — has a heating capacity
of about 28,000,000 units. A barrel of petroleum (42 gal-
lons, or about 275 pounds) has a heating capacity of about
3,500,000 units, or one-eighth as much as a ton of coal.
Under ordinary conditions a grade of 180 feet to the
mile would suffice for a self-acting gravity tramway.
The weight of the car, the load, the size of the cable, the
length of the line, are among the factors in the matter.
SO far as known, native copper is found in Arizona
only in the Buster mine, Bradford mountain, where it
occurs in leaf-like sheets in maximum size of 6x14 inches,
and ',-inch thick. It is more in the nature of a deposit
than vein matter.
Kaolin is not an uncommon deposit, nor of especial
value. Ordinarily a kaolin bed will yield about one-third
" China clay," as the material used is called. Unless spe-
cially favorably located, transportation charges would
eat up the profit of production.
A "MILL run" of ore is ordinarily understood to
mean a test of the value of a lot of ore large enough to
be run through a quartz mill. It cannot, in that sense,
be justly applied to a sample or small quantity. A " mill
run " deals with tons, rather than pounds.
The advantage and superiority of the metric system is
unquestionable, and some day the United States will
adopt it. We are a conservative people in some things,
and it is only conservatism and inertia that keep in use
the present system of weights and measures.
To platinize fine copper or brass articles take 800
grams sal-ammoniac, 10 grams platinum-sal-ammoniac
and heat to 212° F., with 400 grams water in a porcelain
dish, place the article to be platinized therein, remove
after ten minutes, dry and polish with whiting.
Henry Pichoir of San Francisco died October 24,
1898 ; Capt. Thomas Mein died at Oakland, Cal., on
May 4, 1900; Hamilton Smith, as noted in last week's
issue, at Durham, N. H., on the 4th inst. Many of the
old and famous California miners are passing away.
A belted governor is not reliable in regulating the
speed of a dynamo engine. The belt creeps irregularly
under variation of speed in the governor, and has un-
equal tension from variation in the moisture of the engine
room. It is also liable to slip and more liable to accident
than gear-driven governors.
A lien for wages given by statute on all the property
of a corporation in preference to all other liens except
recorded mortgages and deeds of trust, in case of failure
to pay employes monthly, is held (in Johnson vs. Good-
year M. Co., 47 Cal., L. R. A., 338) to constitute an un-
constitutional discrimination against corporations and
their employes.
Regarding the statement in the issue of June 30, con-
cerning hard-drawn copper wire, it is to be further said
that soft-drawn copper wire is best adapted for dynamos,
motors, etc., and any place where the wire must be bent
to short turns, and where flexibility and high conductiv-
ity are the essential points. Hard-drawn copper wiro is
best adapted for line work, such as telephone lines and
electric railway trolleys and feeders, or where the ability
to stand strain without stretching or sagging, is neces-
sary.
Mineral entries of public land can only be made under
the mining law; in homestead entry residence is compul-
sory; desert land entry costs $1.25 per acre — 25 cents
when entry is made, remainder when proof is made.
There must also be an expenditure of $1 per acre per
year for three years tending to the reclamation of the
land.
The California State Mining Bureau will, without
charge, tell if certain metals or minerals are or are not in
a sample submitted — that is, will make a qualitative
analysis, but will not state in what quantity or propor-
tion they exist in the proffered specimen. That depart-
ment of the bureau answers about 1200 such questions
annually.
Dredging and drift mining are two forms of gold
mining destined to be of great profit in California and
elsewhere. The latter requires more capital and pluck
than the former. Dredging offers about as near " a
dead sure thing " as any form of mining can, where judg-
ment is used in the selection of ground and in the
mechanical appliances.
It is with a patented claim as with any other real es-
tate : optional with the owner whether it be utilized or
allowed to lie idle year after year. Nor can any one other
than the owner do any work or development thereon
without his consent. Even the Federal Government
parts with all power over it, and the patented property
is subject only to State and local taxation.
In the chlorination process an extraction of 98% is
possible, if concentrates are very rich; but all depends on
the character of the ore treated, as the tailings from
some concentrates are high while others are correspond-
ingly low; 90% or 92% extraction is very good on the
average concentrates. As to the consumption of chemi-
cals to the ton of ore, that also depends upon the charac-
ter of the ore treated.
Carbolite is a by-product of iron making; it is a
combination of carbon, calcium, aluminum and silicon,
and from it is produced ethylene gas — a sort of improved
acetylene, and produced at 50% less cost. For every ton
of pig iron made, about 13,000 pounds of substance has
gone to waste. Some of the slag has been used for bal-
last, cement and the manufacture of mineral wool; this
latest product utilizes more of the former waste in iron
manufacture.
In a 12-foot piece of lumber, 4x4 inches at one end, 6x6
inches at the other, there are 25} feet b. m. To take the
mean would give 25 feet; to take the contents top and
bottom would give 26 feet. The accurate result is
reached by assuming the stick extended to a perfect
pyramid, then subtracting the top pyramid from the
whole; the pyramid would be 36 feet long and would con-
tain 36 feet; the lesser pyramid would be 24 feet long and
would contain 10| feet; the difference is 25} feet.
A SOURCE of waste steam is leakage from the safety
valves. Boilers need not blow off just at the working
pressure. The safety valve may be adjusted to lift at five
pounds above the working pressure — that is, if it is
tight on its seat. A badly seated valve will blow off
below the working pressure. Such a valve needs grind-
ing in with fine emery powder. It is a lazy and danger-
ous practice to put a weight on the lever of a safety
valve to prevent steam escaping. Grinding in is the only
true remedy.
In preparing white lead by electricity, a mixed solu-
tion of carbonate and chlorate of soda is subjected to the
process of electrolysis ; chlorate of lead is formed at the
anode or lead plates by which the current enters the
solution, and soda at the plates by which it leaves. The
chlorate of lead forms, in contact with carbonate of soda,
the hydro-carbonate of lead. The bath is agitated so as
to keep it homogeneous and let the white lead fall to the
bottom as it is formed. The soda is afterwards treated
by a current of carbonic acid gas, which regenerates the
carbonate of soda.
In 1895 the Le Roi mine, Rossland, B. C, contracted to
deliver 75,000 tons of ore to a smelter to be built at Trail,
B. O, 11 miles from the mine. At the Trail smelter the
freight and treatment cost $10 to $14 per ton ; 95% of the
assay value of the gold and silver was paid for, and 1.3%
reduction made on account of copper. By the time the
Trail contract was ended the Le Roi built a smelter at
Northport, Wash., just across the line, where the cost

TO set borts in a diamond drill it is found by some ex-
perienced men that instead of setting the stones at regu-
lar distances in the face of the bit or crown that it is
better to fix them in groups of twos or threes, leaving be-
tween the groups spaces of sufficient area to put in four
plugs or pins of iron. These are firmly tamped in and
left a sbade long, so as to project a little beyond the ex-
posed portions of the diamonds. The result of this is,
that before the diamonds come into operation the iron
plugs are gradually worn away until each diamond comes
into work without undue prominence, and the risk of
fracture when coming into contact with hard joint rock
is obviated.
To clean MERCURY, many different ways have been
repeatedly published herein. Probably in addition to
1
what has already appeared anything good would not be
new, and anything new might not be good. The follow-
ing is recommended : Get a wooden half barrel or tub
with faucet to draw off from the bottom ; tilt at such an
angle that the mercury put in may collect around the
faucet; get a pound of per-chloride of iron (in lump, not
in solution). The tub being half full of warm water, put
in two lumps of the per-chloride, the size of walnuts,
which should suffice for half a flask of mercury. Pour
in the mercury and stir in the solution for six or eight
minutes; let it stay twelve hours, giving it an occasional
stirring. The mercury is to be drawn off as needed.
The solution should clean the mercury without affecting
it otherwise. An occasional little chunk of the per-
chloride will keep the solution sufficiently strong. When
it gets thick and foul it should be cleaned out and re-
newed.
With the development of larger and more efficient
dynamos the effort has been to establish central power
stations for transmitting energy electrically over large
territories. This system has attained its highest develop-
ment in the harnessing of natural cataracts. In speaking
of electric energy the engineer thinks of two things:
First, amount of electricity flowing through the wire;
second, the force with which it is being driven along.
This force is known as voltage, electricity flowing as the
current; thus a certain current is transmitted at so many
volts. By experiment it is known that the main loss of
energy is due to heat radiation from the transmission
lines and that this heat varies directly as the resistance of-
fered to the current and as the square of the value of the
current. From this it is seen that if only a small amount
of current is conducted the per cent of loss is much re-
duced; the problem is, then, to transmit the electric
energy in the form of a small current and at the same
time provide for the development of a large amount of
power where it is to be utilized. To do this the practice
is to generate an electric current at a moderate voltage
and, by means of suitable apparatus, convert it into a
small current at high voltage. This high voltage cur-
rent is transmitted to the point of utilization where the
electric energy undergoes a reverse transformation which
brings it to its original condition and to one better
adapted to the propelling of machinery. The use of a
small current at high voltage is analogous to that of a
small water pipe conveying water under high pressure.
Suppose two pipes varying widely in diameter to conduct
water from "a" to "b. " To transmit the same volume
of water by each in the same time the water in the small
pipe must evidently have a much greater pressure, or
rather velocity. These two pipes may be made to fill two
equal reservoirs in the same time and thus each made to
do the same work. Just so in the case of electric trans-
mission; the same power can be conveyed either by a
large current at low voltage or by a low current at high
voltage, but as the heating is much less in the latter case
it is the method that is commonly used — in fact, it has
rendered the long distance transmission of electric energy
possible.
The automatic compression of air by a column of wa-
ter flowing down a shaft, referred to on page 547 of the
issue of May 19, is a device for obtaining compressed air
by the direct act of falling without the aid of any moving
mechanism and depends upon the principle of the
Sprengel pump. If a stream of water or any other
liquid is allowed to fall down a vertical tube, into which
air is also suitably admitted, each drop of the falling
fluid will entangle and carry down with it a globule of
air, the drops of the liquid forming pistons, so to speak,
in the tube, which force down and compress the air. Its
typical form is that of the trompe, the blowing machine
used in the old extinct Catalan forge, which is said to
have been invented in Italy as far back as the year 1640,
but in these somewhat primitive forms the blast pressure
was always low and the efficiency did not exceed 15%.
The compressor referred to in the answer to the Red-
ding, Cal., correspondent in the issure of May 19, con-
sists essentially of a head tank, a vertical down-flow pipe,
and separating tank placed at the base of the down-flow
pipe. The water may be conveyed to the head tank by
means of an open flume, or pipe; water entering the
down-flow pipe passes the ends of a number of small air
pipes, from which air is drawn in the form of small uni-
form globules, which, becoming entangled in the descend-
ing water, are carried down to the air tank, where sepa-
ration takes place, the air rising to the top of the tank,
and the water flowing out at the bottom, and up again
outside the down-flow pipe to the tail race. The differ-
ence in height of the tail race and pipe to head tank
gives the available head of water. The globules of air
are uniformly compressed at constant temperature dur-
ing their downward path, the temperature of the water
remaining practically constant. The amount of compres-
sion of the air depends solely on the length of the down-
flow pipe, being independent of available water fall. In the
case of the machine erected at Magog, Quebec, the depth
of the shaft is 128 feet, its size 6x10 feet; the down-flow
pipe is 3 feet 8 inches in diameter; the inverted tank at
the bottom of the shaft is 17x12 feet. The penstock, or
inflow pipe, is 5 feet 6 inches in diameter, and in the
headpiece there are thirty air pipes, each 2 inches in
diameter, and each having thirty-two air inlets at their
base, making a total of 960 air inlets. Through these
the air mixes with the down-flowing water, thus sub-
dividing the air into an innumerable number of small
bubbles. The available working water head is 21 feet.
Tests made by Mr. McLeod, of McGill University, in-
dicated that the plant gave an efficiency of 60% of the
actual H. P. of the water in dry cold air.

The Cripple Creek Volcano.*
The Cripple Creek district occupies a cluster of
foothills on the south side of Pike's Peak, Colo. 'It is
essentially a small volcanic area, of about 20 square
miles, amid the granite of the Front range. The
mines are situated amid a volcanic complex, consist-
ing of tuffs and breccias, which have been penetrated
by an extensive system of dykes and other intrusive
masses. The prevailing formation is an andesite
breccia, which lies upon the worn surface of the
granite and fills the deep basin around a volcanic
vent. The breccia, since its deposition, has been
broken into by several eruptions of phonolite, and,
later still, by a series of thin dykes of basalt and
other allied rocks of a highly basic composition.
The Cripple Creek district represents the ground
floor of a volcano, the superstructure of which has
been removed by erosion.
At Cripple Creek the mine workings afford a good
deal of information concerning the underground
structure of the region. It is hoped that an inquiry
into the history of the volcano which determined the.
interesting character of the district will contribute
toward a clearer comprehension of the geology of the
mines.
The operations of nature in the past are inferred
from the observation of those which take place to-
day. The intensity may vary ; the forces are the
same. This is the cornerstone of modern geology as
laid down by Lyell. The volcanic complex at Cripple
Creek is to be understood in the light of the evidence
gathered for us by the patient investigators who
have stood by the side of the craters of Stromboli,
Vesuvius and Kilauea.
The conclusions of those who have made a specialty
of this branch of geology may be summarized thus :
The explosive violence of volcanic eruptions is due to
the access of water to the fused rock within the con-
duit of the volcano; but, as it appears that this water
is not contained within the substance of the lava
emitted during the tranquil emissions succeeding the
first paroxysmal outburst, it is inferred that the
water is not the primary cause of volcanic action,
which originates at a depth greater than that to
which it is believed that water can penetrate. The
evidence collected is not complete ; but it warrants
a reasonable conjecture that volcanoes owe their
origin to the contraction, caused by the cooling of
the earth's crust upon a yielding substratum, sepa-
rating the solid outermost shell from an equally solid
nucleus. While, therefore, the force which pushes
large quantities of fused rock to the exterior of the
earth has, probably, a deep-seated origin, neverthe-
less, the immediate cause of the uncertainty, the vio-
lence and the magnificent energy of volcanic action
is traceable to the effects produced by water coming
into contact with the lava as it approaches the sur-
face.
The volcanic rocks of the Cripple Creek district
have come up through the granite. It underlies them
all ; they rest upon it, and can be seen penetrating it
in the form of dykes. Previous to the first eruption,
the granite must have presented a weatherworn
surface, such as characterizes the high hills. Ever
since its first emergence from the ocean this region
has been undergoing an intermittent elevatory move-
ment, which culminated in making the Front range.
Erosion had been continuous, but the uplift more than
counterbalanced such wearing away; and the granite
hills had been slowly raised far above the Cretaceous
seas which washed their edges in the era preceding
that to which the eruption is assigned. The forces
which had done this work were of the most patient
kind ; their manifestation had about it nothing of a
violent or paroxysmal character ; time was an essen-
tial element of the process.
At the close of the Eocene period this apparent
equilibrium was disturbed. The foundations of the
granite hills trembled. Slight tremors were followed
by earthquakes, and these were the precursors of
greater violence.
There is ample evidence that water does not pene-
trate into the conduit of the volcano, and that it is
originally derived from the surface. As against the
contrary belief, namely, that the water vapor accom-
panying eruptions is an essential constituent of the
lava, and, therefore, shares with it a deep-seated
origin, there is the following evidence : It has been
found, as the result of a large number of accurate
observations in wells, shafts and boreholes, that the
temperature underground increases 1° F. for every
48 feet of descent. At 7776 feet, the boiling point,
and at 34,700 feet, the critical point, 773° F. of water
would be reached. The expansive force of steam in-
creases rapidly with the temperature, so that at
773° F. it would be equal to the pressure of 350 at-
mospheres. This is termed the " critical point " be-
cause at this temperature water, however great the
pressure to which it is subjected, can no longer exist
as a liquid, but becomes dissociated into its constituent
;ases. Although the exact conditions which obtain
t these great depths can not be known with cer-
ainty, nevertheless, all the evidence goes to show
♦Condensed from a paper read at the Washington meeting of the
A. I. M. B. by T. A. RIOKABD.
that there is a limit set to the descent of surface
water by the rapid increase in the expansive force of
its vapor, due to the rising temperature. Prestwich
put the maximum limit at 6 to 7 miles, and Delesse esti-
mated it at 60,000 feet, or about 11 miles. Moreover,
experience goes to show that the water encountered
in mines is the drainage from the surface. Deep mines
are usually dry ones. I may instance the deepest
metal mines, the Calumet-Hecla and Tamarack, in
the Lake Superior region, and the 180, New Chum-
Victoria and neighboring shafts, at Bendigo, in Aus-
tralia.
The evidence obtainable concerning the first erup-
tion of the Cripple Creek volcano is necessarily very
meager. The first vent must have been formed at
some point along one of the fractures caused by the
earthquake shocks ; the lava, in forcing for itself a
way to the surface, being aided by the force of the
expanding steam. The pressure required to break a
passage through the overlying rocks is stupendous ;
and, as a consequence, when the steam accompany-
ing the lava is finally and very suddenly released from
that pressure on its immediate arrival at the surface,
it escapes with explosive energy and with projectile
not particularly well defined, because the face of the
enclosing rock is shattered. The most peculiar fea-
ture of the section is presented by pellets, nodules
and rounded fragments of dark-red scoriaceous lava,
which occur all through the material filling the vent.
At the edges rounded inclusions of this lava can be
seen in the mass of fragmentary granite ; and in the
center the lava, by reason of oxidation, forms a red
granular matrix, in which large pieces of granite are
separately discernible. The material, especially near
the edges, has a laminated structure, parallel to the
sides of the vent. These laminations vary in thick-
ness according to the coarseness of the material.
This illustration is of great interest. The vent is in
granite, as was the first vent of the volcano. It is
now filled with breccia, as at one time that was. The
shattering of the sides is suggestive of the mode of
formation of the breccia, which now fills it. Had this
vent been further enlarged, and subsequently pene-
trated by phonolite, not in fragments, forming a
breccia, but in liquid form, solidifying to a compact
mass, it would have presented a complete anology to
the Cripple Creek volcano.
After the first outburst, a change took place in the
volcanic vent in granite, at victor, cripple creek.

discharges which may reach to an astonishing height.
Thus, when the outburst of Krakatoa, an island near
Java, occurred in 1883, the finer fragments ascended
skyward 10 miles and were recognized in the atmos-
phere of London. The winds carried the dust of
Krakatoa around the world, and thus gave rise
to the extraordinary sunsets observed in the autumn
following.
The Cripple Creek volcano first ejected fragments
of granite. They were probably small in size, and
became further reduced by colliding with each other
as they were discharged, so that they fell to earth in
showers of particles like gravel. Of this first erup-
tion there is little trace now, unless the grits of
Straub and Grouse mountains be the remnants, as is
probable, of the debris accumulated at that time.
Material resembling this must certainly have covered
the surface around the vent, until the larger portion
of it was washed away. The steam, which in enor-
mous volumes accompanies the first outbursts of vol-
canic action, becomes condensed as soon as it issues
into the cold air and forms rain clouds, the downpour-
ings of which frequently removes the accumulations
formed at the initial stage of the volcano. The floods
which succeed eruptions are due to the super-
saturation of the atmosphere with the water vapor
emitted by the volcano. Such floods are more feared
by the dwellers around Vesuvius, for example, than
the lava streams, the destructive effects of which are
comparatively restricted. It was the formation of a
liquid mud, by the action of heavy rains on the fine
material, called tufa, which buried the city of Her-
culaneum.
It is unlikely that sufficient data will ever be forth-
coming to give an exact presentation of the chief
vent of the Cripple Creek volcano, unless one of the
millionaires, enriched by the gold he has won from
the mines, shall undertake the requisite explorations.
Yet some very interesting information on this point
is available. A miniature vent exists near the town
of Victor, and the railroad has cut through it, so as
to furnish the section of it shown in Fig. 1. As a
hand specimen may exemplify the structure of a
mountain range, so this small vent typifies many of
the characteristics of the orifice probably existing in
the earlier stages of the Cripple Creek volcano.
This vent occurs in the massive granite of Squaw
mountain, about 1700 feet south of the main breccia
formation of Battle mountain. In the railroad cut,
where it is to be. seen, it has a width of 35 feet. It is
filled with fragments of granite and the gravel de-
rived from the brecciation of granite. The edges are
matter ejected by the Cripple Creek volcano ; there
began to appear the fragmentary andesite which was
destined to be accumulated to such an enormous
thickness. It may be that flows of andesitic lava also
welled out over the surface at this time. If so, they
were subsequently eroded. During the long intervals
of quiet separating one period of eruption from
another, the lava became cooled, cracked, and then
disintegrated by rain and frost, so as to be broken up
and carried away by the mountain streams so as to
form a part of the alluvium of the valleys. Thus the
superficial flows were removed ; but the correspond-
ing bodies of lava which consolidated underground
when the extrusion at the surface had ceased, are
now, thanks to that very erosion, to be seen as bodies
of andesite rock in several parts of the district, nota-
bly on the eastern side of Battle mountain and near
Legal Tender hill, above Goldfield.
At this period similar outbursts were occurring
among the neighboring hills, for the Cripple Creek
volcano was but a minor incident among the eruptions
which during the Tertiary epoch spread a vast thick-
ness of breccia and lava over a large portion of south-
ern Colorado. Out of the products of these eruptions
were sculptured the serrated peaks of the Uncom-
phagre, the Cleopatra hills and the rugged ranges of
the San Juan.
After the eruption had continued sufficiently long
to form a vast accumulation of the fragmentary ma-
terials, which in process of time became consolidated
into breccia, there came a period of comparative
quiet.
(to be continued.)
Two slow but interesting changes are taking place
in Behring sea. The immense quantity of debris that
is borne down the Yukon from its sources and sides
is being deposited in the sea beyond the mouth of that
mighty stream, and its weight causes the bed of the
sea to subside. A corresponding rise in the earth's
crust is going on along the chain of the Aleutian
islands. Not only are the islands themselves increas-
ing in size in consequence of being lifted up out of the
water, but new islands are being formed in the gaps
between the others. In some instances the new
islands are the result of the rise, and in others they
are the result of volcanic action. Most of the Aleu-
tians are of volcanic origin, and they mark the posi-
tion of a fold in the earth's crust that is predisposed
to eruption. In time there is likely to be a natural
bridge from America to Asia along this route, but
nobody now living is going to see it.

The Factors in Concentration.
On attempting to segregate the (actors in concen-
tration into various groups they are found to vary
regularly from purely commercial at one end to
purely technical at the other.
Those from the extremities of a comparative list
can be readily grouped, but the greater portion have
their commercial and technical aspects so related
that nothing is to be gained by attempting to con-
sider them separately. Profits — the commercial as-
spect — mean that returns minus costs must have a
positive value. The word "returns" is used to
stand for the sum of all commercial values in the con-
centrates. The costs are made up of concentration,
transportation of concentrates to point of sale and
refining.
Considering the totals of any given proposition, the
general law is that the greater the concentration
the greater the loss of values ; that is, the smaller
the weight of material delivered for sale at point of
refining the smaller would be the amount of values
delivered for any given tonnage treated by concen-
tration. The two practical limiting cases are :
First. — Where no concentration takes place and all
the values are delivered, the cost of concentration
being zero and transportation and refining each a
maximum.
Second. — Where pure values are produced and the
miuimum amount delivered, the cost of concentration
being a maximum, the cost of transportation being a
minimum, and the refining cost reducing to zero.
This statement of the miuimum limiting case ex-
hibits the marked peculiarity in the form of the func-
tion expressing this general law, which, in definite
concentrating problems, very greatly reduces the
limits between which a solution need be sought. That
is, the degree of concentration does not approach in-
finity as a maximum, but a definite value which is
usually sharply determined by the existing mineralog-
ical and industrial conditions. To the stamp mill
man the definite demarcation between the specific
gravity of the pyrites carrying his concentration
values, and the accompanying silica or silicates,
clearly indicates the minimum limit of his concentrat-
ing problem. In these same concentrates later the
matte smelter finds as definite a minimum limit for
his problem in the equally marked differentiation of
the copper contents.
Yet, while both theoretically and in a general way
these limits are well marked, in practice there is a
marginal zone within which the more profitable course
of operation is not evident from inspection. This is
caused by :
First. — The fact that the influence of factors other
than the specific gravity (such as surface tension,
etc.) is modified by the character of the crushing that
preceded the concentrating ; and
Second. — By tbe fact that no practical limit of
crushing will entirely release the materials whose
separation is sought. Thus, instead of there being a
sharp margin up against which concentration can be
carried, even in cases where the difference in specific
gravity is marked, the limit is made indefinite by the
presence of particles, mechanical mixtures of vary-
ing proportions with specific gravities varying over
the entire available difference. Within the marginal
zone occur the problems of concentration, the solution
of which is not a matter of off-hand professional ex-
perience, or of accumulated constants and data, but
of comprehensive testing.
General experience (plus constants and data) will
be of value in regard to the limits of this zone, and in
the cases outside of it can, giving the transportation
and refining factors, furnish a solution, both in re-
gard to total investment and details of plant. Such
a case would be the small concentrating plant usually
placed below a stamp mill, or, in general, any propo-
sition where on account of high transportation aud
refining charges the margin between smelting and
concentrating ore is large.
In such cases the criterion is the law of operation,
that the saving will be higher the greater the invest-
ment per unit of ore handled. That is, the saving
will increase with the investment and decrease with
an increase of tonnage for any given investment. At
the same time with increased investment comes in-
creased cost as well as increased saving.
But while both the saving and cost of operation in-
crease with the investment per unit of ore handled,
the ratio of each to the investment is not constant,
nor do they vary according to similar functions.
Starting from the intermediate point where both cost
of operation and investment are zero, the ratio of in-
crease of cost of operation to increase of investment
rapidly falls from that found in small, under-capital-
ized plants to a value near, but slowly approaching
unity. A closer analysis of this function shows that
it is the sum of two co-operating effects, one due to
investment in actual concentrating machinery, which
adds in a direct proportion to the cost of operation,
and the other, the investment in handling the machin-
ery, to the effect of which can be traced all the
variating in the ratio.* Within the practical limits
between which any given concentration problem must

Mining Institute.
I"' solved, this change in ratio may be neglected. (A
200-ton concentrator may be run with a lower cost
in than one of fifty ions, but the fact isofm
(Then only fifty tons of ore are available.) In other
words, if the investment per ton handled be doubled,
the cost per ton will also be doubled.
Consider the simple case of a concentrating ma-
chine at work : Will it pay to split its load over two
machines? If the saving increased proportionate to
the investment it obviously would pay; but it is
equally obvious that the saving can not increase in
this way, for, no matter how large the investment, I
no more values can be taken from ore than it con-
tains. That is, while the investment varies from zero
to infinity the saving varies from zero to unity.
With any given set of conditions, values, freight
rates, smelter charges, depreciation, interest, labor,
costs, for some given investment, the ratio of returns
to costs must reach a maximum, this being a mat tor
of comparatively simple mathematics to formulate.
The difficulty at present lies in the fact that almost
no work has been done towards determining the con- I
stants of such a formula, these constants having to
be determined for each type of concentrating machin-
ery. Some tentative testing with vanners under the !
necessary conditions of uniform surroundings showed
that the ratio of investment to saving could ;
be expressed closely enough by using three terms ;
of the general conic equation, differentiating
for the maximum value. But the desirability ;
of using more than three values in the determination
of the constants and the reduction of the constants
so obtained to a single most probable formula by the
method of least squares, makes the work, while
simple, so tedious that the graphic method of plot-
ting a curve has been found much the more suitable
for general practice.
The accompanying curve plotted from the following
values experimentally determined from 6-foot side-
shake vanners illustrates the method :

That is, with eight times the investment the net
return is less than with one machine, although the
amount of values shipped is greater.
By selecting various points on the curve the net
result for various numbers of machines can be ascer-
tained until the most profitable one under assumed
conditions is determined.
This method as outlined is capable of ready appli-
cation to the average concentrating problem. Given
the data from which to plot the curve, the other fac-
tors will usually be found fixed.
To obtain the curve data it is not necessary to have
available a varied number of machines, but ihe same
results can be even more readily obtained from one
machine by varying the amount of pulp handled. It
should be noted that in such testing results obtained
by hand panning of heads and tails are unreliable.
The better plan is by analysis ; in the common case
of sulphides, analyzing for sulphur and in other cases
for the constituent element that accompanies the
concentrating values. As with the average concen-
trating machine the differentiation of gold is only in-
cidental to the gold accompanying some more abun-
dant material, assays are misleading in questions of
relative saving. Further, in recording such tests
that they may be of general value, the actual size of
the maximum sized particles experimented with
should bo stated in millimeter and not in the indefinite
phraseology of " mesh."
In cases where the proportion of concentrates is
less than 5%, the variation due to a change in the
concentration ratio can be neglected.
The question of crushing, while a definite factor in
concentration, is usually so limited in range by the
mineralogic and physical features of the ore as to
render it practically as fixed a quantity in any con-
centrating problem as the smelter charges on the
product.
But while the size of the product to be concen-
trated is presented in, is thus definite for a given
case, it exercises a controlling influence
on another factor in concentration — the
type of concentrating machines to be
used. In general, all practical machines
make use of the varying ratio of the
surface friction in some medium to the
weight of the particle ; in most, agitation
being used to overcome the difference be-
tween the friction of motion and the fric-
tion of rest. The classification of a
charge of particles being so effected, to
render the process continuous requires
that the classified particles be removed
from the machine without admixture.
From the method used to accomplish
this, concentrating machines may be
grouped in three types : those that dis-
charge the concentrates through the bed
they have settled on — such as the jig ;
those that shake the concentrates off
of one edge of the bed — such as the
modern stratifying tables — and those
that remove the bed with its accumu-
lated load of concentrates — such as the
buddle and the various forms of vanners.
The differentiation of these types re-
sults from the fact that in the ratio, on
which concentration depends, that of
weight of particle to surface friction in
some medium, this factor of surface fric-
tion is the resultant of two factors, the
form of whose function differs so much
as to make them practically independent vari-
ables. One is the friction of the liquid medium
on the particle ; the other is the friction be-
tween the particles and the surface that supports
it. In the hydraulic classifier theoretically this fac-
tor is zero. In the jig is a minimum, greater in the
shaking tables and is a maximum in the moving bed
type of concentrators. Its proportionate influence
on the total factor of surface friction is a function of
the lineal dimensions of the particle, the influence be-
ing a maximum for the minimum sized particle and at
a minimum with the larger sized particles.
A concentrating machine can be expected to do the
best work when the ratio of these two factors of fric-
tion against fluid medium and friction against sup-
porting surface, as used in its operation, compares
most closely with the ratio of the influence of each on
the mass of the given particle.
It should be noted that while the form of the func-
tion expressing this ratio remains the same for dif-
ferent materials, the constants in the function
change. That is, with a given material to concen-
trate, such as galena, a certain-sized particle will
always call for a certain type of machinery, while the
same size of particle would probably require a some-
what different type of machine in the case of a differ-
ent material, such as barytes. For most of the com-
mon mineral mixtures the best type of machine for a
given size particle has been settled by the empirical
experimentation of centuries and is recorded in
the design of profitable plants in concentrating dis-
tricts throughout the world.
Machines of a given type may differ in their me-
chanical arrangements for carrying out their typical
work, but this difference should not be confused with
the metallurgical difference of type. The fact that
there are no sharp limits between which any type_ of
machine must be used, the efficiency simply running

down as it is used with other than its most efficient
size of particle, has helped to confuse the distinction
between mechanical and metallurgical adaptability,
usually at the expense of the latter.
While the voluminous experience in concentration
has broadly settled the relation of type of machine to
ore particle, there is great desirability for compre-
hensive testing over the limiting margins of each
type; with the jig, from one-fifth millimeter down;
with the stratifying machine, from 1-20 millimeter
down, and with vanners up towards two and three
millimeters. Here, when the usefulness of these
machines overlap, the difference in adaptability is too
small to be decided by inspection and awaits system-
atic recording.
Summarizing. — Each concentration problem must
be solved twice; first, backwards from general fac-
tors to details; then forward with settled details to
a definite general result.
Starting with the general transportation and re-
fining factors, the limits are found between which
concentration is possible at any geographical point.
Next, the physical conditions of the problem under
consideration determine the types of crushing and
concentration machinery and capacity of plant.
Lastly, the values in the ore determine the invest-
ment; that is the number of machines of each type to
be used per ton capacity to be desired. Then with
these definite quantities applied to the general fac-
tors, the solution is retraced and a definite showing
decides-whether the return minus the costs will have
a positive value.
There is to-day no risk in concentrating invest-
ments, aside from inefficient business management.

A thkee-candle-power incandescent lamp is an-
nounced by T. A. Edison, the use of which, it is
claimed, will prevent colliery disasters. The law
governing the inspection of mines in Pennsylvania
makes it mandatory that • the lighting thereof,
whether portable or stationary, shall have the ap-
proval of the chief of the inspectors, for on his judg-
ment and intelligence is supposed to depend the
safety of thousands of lives and millions of dollars in
property. Application has been made to J. E. Rod-
erick, chief of the bureau of mines in Pennsylvania,
to order the use of the Edison system in place of the
oil and gasoline lamps. The invention is a primary
battery, in which the pots, carbons and (all connec-
tions are fixed. It is claimed that a box weighing
4* pounds will maintain a three-candle-power lamp
for ten hours at a cost of 2 cents. A bevel-plate glass
covers the lamp. Should this glass be broken by
accident or design, the light is extinguished. No heat
is evolved, and it is impossible to ignite either vapor
or substance. From 1887 to 1896 the number of miners
who lost their lives in the United States through ac-
cident was 8140, and fire damp was responsible for a
large number of them.
Sturtevant Roll Jaw Crusher.
Crushing is the first and least expensive step in
rock reduction, as any standard breaker will reduce
the hardest ores at a minimum cost. Well-managed
works seek to do as fine work as possible in the
crushers. With intent to supply this requirement
without tendency to clog, the Sturtevant roll jaw
crusher, whose jaws can be set without danger of
clogging to } inch, has been designed. Its moving
jaw does not approach and recede, but rolls opposite
the fixed jaw, rolling over the rock to be crushed,
which drops out after the rolling jaw has passed over
it. Thus it is free to drop out, and only really sticky
ores clog. The Sturtevant roll jaw crusher, here-
with illustrated, is of the true jaw and toggle type,
designed to be durable and effective for hard rocks,
and it is claimed by its manufacturers that its un-
usual power, due to long leverages, makes it an
easier running machine, rock breaks easily when roll-
ing, and biting pressures are applied at the same
time. In this the rock is reduced by rolling stresses
without any rubbing action, promoting durability.
The cut illustrates a 5x24 roll jaw crusher, weighing
about 22,000 pounds and requiring about 15 H. P.
When the faces of the roll jaw crusher are set to
1-inch, they take in as large rocks as a breaker of
equal size, reducing them at once to gravel and sand,
suitable for mills or finishing rolls, thus designed to
do the work at one operation. They can also be set
to do the common coarse breaking.
The Sturtevant roll jaw crusher is designed to last
and to give the least possible trouble ; its jaws are of
steel and the toggles for all hard work of bronze. It
is made by the Sturtevant Mill Co., Boston, Mass.

Born Before the Rood.
A cedar tree, whose age has been reckoned by
geologists at 25,000 years, has been found in Califor-
nia, standing in an excellent preserved state, the
fibers so perfect and the wood so strong that it was
used for timbering in the construction of a mining
I tunnel. This remarkable instance of the preservation
| of organic remains was found in the heart of a moun-
I tain, nearly 500 feet below the summit. This moun-
! tain is a spur of the Sierra Nevadas, near the Forest
Hill divide, in Placer county, between the north and
middle forks of the American river.
The mountain is lava-capped with one of those sing-
ular table tops which show that there was once a day
when all those ravines with which the region now
abounds did not exist, and that what is now the crest
of the mountain was once the lowest plane in a topog-
. raphy vastly different from that which exists to-
, day. For all of these millions of tons of lava material
were incumbent upon a river bed, and
it was on a bank of this river that
this cedar tree grew, and here it was
found standing, 100 feet in height,
25,000 years after its submergence.
The lapse of time since it was thus
sealed to the world can not be more
than approximated. It is known that
its inundation occurred during the
Pliocene period and that this was a
Pliocene tree ; the geologists of Cali-
fornia estimate that the Pliocene pe-
riod ended about 25,000 years ago.
The ancient river bed on the bank
of which the tree stood contained gold,
and it was in quest of this that the
vitals of the mountain were probed
and the tree discovered. Several
small oaks, having the appearance of
what is common in the arid parts of
California as scrub oaks, were also
found upon the same and opposite
bank of the dead river, but they were insignificant
as compared with the majestic bearing and per-
fect preservation of this strong and noble cedar.
All vestiges of needles had disappeared, but some
of the elongated tips of the branches remained,
and many cones were found upon it. These crumbled
to dust as soon as brought to the air ; as also did the
bark, but the wood was firm and sound, the trunk
being about 3 feet in diameter at its base, the roots
tough and of the tenacity of seasoned wood. — West

Quartzite and Whin.
To the Editor: — In last week's "Concentrates"
"whin" is stated to be quartzite. Quartzite is
metamorphic sandstone of sedimentary origin, but
whin is a term applied to igneous rocks, popularly
known as greenstone or trap, and embracing basalt,
diabase, etc.
Whin dykes and overflows traverse the coal meas-
ures and indicate their vicinity by first rendering
bituminous coals anthracitic in character, but closer
approach destroys the coal. Where the whin dyke
is cut through, the same thing, but in opposite order,
is found on the other side : first the "burnt" coal,
then the "blind" or smokeless anthracite, which
gradually, but in a short distance, changes to the
normal bituminous coal. Of
course, this is a positive
demonstration of the igneous
origin of whin.

Concentration of Ores by Petroleum.*
By Charles m. Rolker.
The working of the Elmore concentration process
at Glasdir, Wales, consists in crushing low-grade cop-
per ore by a Comet breaker, followed by smaller ordi-
nary jaw breakers, passing the material to rollers
(crushing wet), and the product of these to 5-foot
Huntington mills provided with No. 6 (jabbed) needle
mesh screens (the fines produced by the Comet are
screened out and fed direct to the Huntington mills).
The undei-lying principles of the process are :
The specific gravity of water being to that of the
residuum oil as 0.89, a given quantity of residuum
oil to a given quantity of water will float on its sur-
face. The residuum oil, of proper consistency, can
theoretically be loaded to 10% before the loaded oil
will sink in water.
The viscosity of the oil is the all-important point.
It varies with different temperatures. The thinner
the oil, owing to higher temperature, the less the
adhesive force and the power of carrying the in-
tended mineral load, although the specific gravity is
decreased and its loading capacity should be in-
creased under No. 1.
It seems that the adhesive property of the oil,
under given conditions, acts with predilection or affin-
ity for bright unoxidized pulverized sulphurets, as
against similarly pulverized rock constituents. (I
am not prepared to substitute the word " metallic "
for "mineral," as the patentee does.)
With a given mineralization in an ore — the required
quantity of oil and its viscosity determined (by pre-
vious experiments on the basis of Nos. 1 and 2) to
bring about a good concentration in a given quantity
of water at a given temperature — the concentrates
grow impurer if the quantity of oil is increased, since
then rocky particles are taken up mechanically
simultaneously with the mineral. The rocky par-
ticles drop out again on allowing time for clearing
and settling. As the latter cannot be done on a large
scale, the right quantity of oil is an essential feature
to start with. These are practically the underlying
principles of the Elmore process.
In a rough outline the mixture of pulverized ore
and water is fed into the end of a drum, which is
caused to revolve slowly on rollers by means of a
worm. Oil is added by a separate pipe, made pref-
erably telescopic to admit of it being discharged at
different distances from the end. At each end there
is a circular opening, and within the drum annular
helical ribs extend from end to end. The spaces be-
tween these ribs are divided into cells by a number of
equidistant blades, to effect a thorough intermingling
of the oil with the pulp and water, without being
broken up. All three are carried to the opposite
end of the cylinder or drum from the one where they
entered, whence they are discharged through a num-
ber of circumferential holes into the subsidence ves-
sel, where the water and sand or pulp are allowed to
subside, the buoyant oil carrying the mineral ingre-
dients floating on top. The oil is admitted at the
same end as the feed. There are. two or three drums,
one underneath the other, the second treating the
tailings of the first, and so on as the case may re-
quire. The feeding of the pulp, as well as of the ore
and oil, is done in the upper cylinder. It is of im-
portance to determine the point at which, in the
length of the drum, the oil is to be admitted. If ad-
mitted at the beginning of the cylinder, the entering
oil would probably take up at once so much of the
mineral as would make it sink in the feed water, and
prevent its floating. The point of entry of the oil
depends on the amount of mineral in the ore, and
must be determined in each instance.
At Glasdir, where the ore impregnation is on the
average very fine copper and iron pyrites in an
altered slate, I ascertained that practice had estab-
* Condensed from paper read at Mining Insfilule.
lished a use of five times the weight of the ore as the
correct amount of the water.
The oil used in the mill is the residuum of distilla-
tion after gasoline, benzolene and illuminating oil
have been removed.
The right amount of oil to be added for the Glasdir
ore Messrs. Elmore determined to be about equal
weights, or one ton of oil to one ton of ore. This
amount varies with every ore. The oil, owing to its
viscosity, will not flow readily, and small rotary
pumps are introduced, acting like meters, propelling
it forward. I found it impossible to determine the loss
of oil by measurement. The storage tank contained
more oil after the test than before, probably due to
the retained water and air. Messrs. Elmore deter-
mined the loss of oil, based on the experience of a
run of over 700 tons, including what is retained in
the concentrates, the tailings and what is lost by
waste, to be two gallons per ton of ore treated. In
my tests I found the amount of oil retained by the
concentrates and tailings to be about one and a quar-
ter gallons per ton. As the test was probably more
carefully made than the 700-ton run, I think it safer
to assume the experience of Messrs. Elmore, that is,
a loss of two gallons per ton of ore with the Glasdir
ore.
The mixture discharged through the holes from the
drum flows, as I mentioned before, into the subsi-
dence vessel. Additional oil may be added to this
vessel, at some distance down, by means of a sepa-
rate pipe, to aid in floating the mixture.
From the subsidence vessel, in which the water and
tailings are drained at the bottom, the oil carrying
the mineral is pumped to a hydro-extractor having a
solid basket with a projecting flange at the top. The
hydro is found to give good results, running from 750
to 800 revolutions per minute. During the action of
the machine the mineral and water pack in vertical
walls, and the oil floating on the water rises verti-
cally on the wall and creeps over the flange, or lid,
of the solid basket and drops into the space between
the basket and the enclosing monitor, and from there
goes to temporary storage tanks, whence it is
pumped again to reservoir or stock tank. The sepa-
rated water is let out through an opening at the bot-
tom, covered with a cone cover, after the machine
comes to rest. The mineral is packed solid along the
inner periphery of the basket. The final draining of
the oil and water is accomplished in a smaller hydro-
extractor with a perforated basket, or periphery, to
which the mineral is transferred. The oil and water
escape through the meshes, and concentrates carry-
ing about 4% of oil and 4% of water remain behind.
I have tested the proficiency of the process on the
very low-grade copper ore from the Glasdir mine,
carrying about, on an average, 1.12% copper, 0.049
ounce of gold per ton of 2240 pounds, and 0.8 ounce
of silver per ton of 2240 pounds. Seven distinct and
separate runs were made on this ore by the inventor
under my supervision, treating in all forty-three tons
of rock. We obtained an average saving of 69% of
the gold, 65% of the silver and 70% of the copper,
with a rate of concentration of about fourteen to one.
This is certainly a good saving when we consider the
low-grade character of the material operated upon.
The percentage of yield of the metals is not the.
final net yield. It is subject to the usual smelters'
charges and reductions for treatment on concen-
trates produced.
If the viscosity of the oil requires to be increased,
the inventor adds from 2% to 3% of mineral butter, a
later distillation product of residuum oil. If owing to
climatic conditions the oil has to be thinned, a pre-
vious distillation product has to be added to the re-
siduum oil. The temperature of the oil and water at
the Glasdir works is kept between 54° and 57°, though
it is possible that wider margins may be permissible.
It is very difficult to estimate the cost of the pro-
cess, but, roughly speaking, it can be taken at that
of crushing and grinding ores to 30-mesh fine, and.
the usual cost of concentrating such ore, plus two
gallons of oil per ton of ore, plus the royalty the own-
ers may charge. All extra cost of oil loss (price at
Barmouth, Wales, 8Jd per gallon) and royalty to be
paid has to be covered by the difference in yield be-
tween wet concentration and this process. I am
convinced this process has individual applicability,
but it would be a mistake to assume that it can be
applied to any and all ores ; its field is limited. How
the oil will act on any of the copper ores besides the
before cited copper pyrites I am not in a position to
say. Each ore will have to be tested, in representa-
tive large lots, before it would be safe and prudent
to draw the conclusion that it can be treated by the
Elmore process.

Central California Electric Co.
One mile north of Auburn, Cal., the main or Bear
river canal of the Yuba Water Co. has a fall of about
200 feet within a distance of half a mile. Previous to
the summer of 1898 the water flowed down Auburn
ravine, but has since been diverted to the canal. At
this point of junction a power house has been erected.
A reservoir, capable of holding a day's supply, was
built at the head of the ravine. The pipe connecting
the reservoir and the power house is of riveted sheet
steel varying in thickness from No. 12 to No. 6 at the
receiver end. It is altogether 3100 feet in length,
the first 20 feet being 54 inches diameter, which nar-
rows to 200 feet of 40-inch and finally to 36-inch,
which size is maintained throughout the remainder of
its length. With the exception of about 200 feet the
pipe is buried at least 1 foot under the surface.
The electrical equipment was furnished by the
Westinghouse Electric & Manufacturing Co. The
generator at Auburn is of the revolving armature
type, 500 kilowatt capacity, 550 volts and sixty cycles
at 300 revolutions per minute. The generator is set
on four blocks of granite which stand on the natural
bedrock, well grouted with cement. iThe cables
from the generator run under the main floor to the
switchboard and thence to the transformers which
are behind it. The transformers, four in number,
are 125 kilowatt capacity each, and transform from
550 volts two-phase, to 15,000 three-phase. High
tension fuses are in a framework under the arresters.
At one side of the building near the main water
wheel, but on the station floor proper, is a 7J kilowatt
exciter, direct connected to a 12 H. P. Pelton water
motor. These are mounted upon the same base.
The regulation is done entirely by using the
deflecting hoods, which throw the water di-
rectly into the tail race. There is no attempt at
saving water as the flow in the canal must be main-
tained at all times. A by-pass is provided to keep up
the supply of water in the canal when the machines
are not running. The main pipe is tapped near the
rear of the building with an 8-inch gate valve, with
a discharge pipe into the tail race; this, as well as
the main pipe in the building, is imbedded in concrete
to prevent any vibration or displacement. At the
rear of the building a 12-inch gate valve in the main
pipe discharges into the ravine.
The main transmission line consists of three No. 4
hard drawn copper wires supported on Locke three
petticoat glass insulators on locust pins, the latter
being boiled in paraffine before using. The poles are
30-foot sawed redwood. The line runs directly to the
Newcastle generating station, terminating in a
marble plugboard with two panels and four sets of
three plugs each. The Newcastle and Auburn plants
are arranged to run in parallel, the current being
transmitted to Sacramento, 29 miles distant from
Newcastle, 34 miles from Auburn. The synchronising
lamps at Auburn are connected in, one on the trans-
former, and one on the generator side of one of the
main switches. In order to synchronise the two plants,
current from the plant which is running is allowed to
flow to the other station, stepping down through the
transformers. The generator is then started, and the
^— ^— switches thrown
in in the ordinary
manner. When
the two stations
are running to-
gether all regula-
tion is done a t

tion. It is found

MINING SUMMARY.
ALASKA.
(Special Correspondence). — There are
now forty-live sailing and steam ships at
anchor- besides numerous tugs and light-
ers ; lightering Is a slow business. Passen-
gers of tho Santa Ana wore unfortunate in
having their baggage burned at sea before
reaching Dutch Harbor, and in being
quarantined, with tho Ohio, at Egg isl-
and, for smallpox. There are .'10,000 peo-
ple here, most of whom are tentod in and
around the city — an orderly, quiet place
considering all things, although there is
some stealing of boats in place of horses,
and other minor offenses, some jumping
ol tn.n lots ending in shooting scrapes
and lives taken. The U. S. Commissioner
Is doing his best to attend to tho police
business, but finds far more than he can
dispose of. If thero is excitement over the
outlook, it is certainly of a subdued na-
ture. There are any number of claims for
sale or lease, owned by the older residents
who wish to return to the States, and
many hundreds of new comers are already
returning, some without going out of
town, who either lack courage or think
discretion the better part of valor. The
departures will increase from now on.
Many Dawsonites arriving "over the ice"
this spring say they have left a better
country than this and are returning, but
none of the new arrivals have had suffi-
cient opportunity to base their opinion on
porsonal experience. The first from Daw-
son via the river and St. Michaels arrived
here June 10. There are several steam
and gasoline pumping plants and all man-
ner of machinery for saving gold being
landed along the beach, principaUy between
Snake and Penny rivers, on ground which
was worked over with rockers last year,
but is now expected to pay with a sluice
head of water. The various degrees and
phases of inexperience of the operators of
some of these plants will account, in part
at least, for the discouraging results ob-
tained in some cases. Some who are rock-
ing on the beach are making from 1 to 2
ozs. a day, but the large majority are only
making grub. Some lucky ones discov-
ered about 800 yards of remarkably rich
beach at Topkok and took out big money;
four men are reported to have taken out
$35,000 each in a week, but say they got
practically all in sight. Pumping plants
will be located there. Preparations are
being pushed for work on creek claims,
and by the middle of next month mining
for this season will he in full swing. Prices
are going down daily. Lumber is now $95
and coal $60 ; square meals, $2 ; two eggs
fried and ham, $1 ; bread, 25 cents a loaf ;
bunks for the night $1 to $4, there being
far too few places for the crowds the ships
are landing to sleep in, people's tents and
outfits being among the freight, which is
landed slowly. Boats are at a premium.
Ordinary whipsawed lumber Yukon river
row boats, 20 feet long, brought $200 each
a week ago, but now sell readily for $100
each. Boat building is a leading industry.
The post office arrangements are wholly
inadequate. One has to wait an hour in a
line of fifty for his turn at the general de-
livery window, if his name begins from A
to L, but if fortunate to have a name be-
ginning from M to Z, he gets his mail
quicker. Freighting in boats holding, say,
two tons, along the beach, is $4 to $8 an
hour ; two horses and wagon, $10 an hour.
Here are some advertisements around
town: "$1000 will buy one of the best
lays in the country, if taken at once."
"Mining claims for sale." "Lot 30x90
feet, facing Front and Beach, $4000."
" For sale, twenty head mules and horses."
"For sale, tundra claim; 25 cents a pan
has been taken out; price, $7000." (!)
" For sale, wagon, team and harness, all
in good shape, $900." "For sale, ten tons
of hay, oats and corn, $12 per ton." " For
sale, a complete sluicing outfit — pumps,
engine, etc. — a snap." Building is going
on rapidly, as lumber arrives. Wages,
carpenters, $1.50 an hour; longshoremen,
$1 an hour.
Nome, June 29.
The St. Paul from Cape Nome, June
27th, arrived in San Francisco July 10th.
She brought $1,500,000, of which about
$100,000 came from Nome, the rest from
the Klondike. All the passengers tell the
same story. Dr. Z. T. Mallaby thinks
there will be worse than the bubonic
plague there soon. "There are about 15
miles of tents along the beach, and it is as
much as a man's life is worth for an out-
sider to venture among them. There is
absolutely no sanitation, and when the
swamp begins to dry up the men will die
like flies in summer from typhoid fever.
Dawson in its worst days could not com-
pare with Nome, and the thought of the
wretchedness that will prevail there next
winter is enough to make a man shudder.
There are at least 30,000 people up there,
and how 20,000 of them are going to live
is a mystery. The stories about $4 an
hour being paid for labor are false; $1 an
hour is the limit, and men are clambering
over each other to nrx that. Nome is
rich. I don't think there is any question
about that, but no one has done any pros-
pecting, as every man is defending his
claim with a shotgun."
Twenty cases of smallpox to July 2 are
officially reported at Cape Nome.

SAN BERNARDINO COUNTY.
The S. P. Co.'s raising of the freight
rate on raw borax from $6 to $28 a ton,
which caused shutdown of the refining
works at Alameda point, is said to have
been rescinded and the former rate re-
stored. The matter was editorially noted
last week. It is stated that the big ad-
vance in freight rates on the crude prod-
uct was made by the railroad company
after it was learned that the borax was
being put through a process at the mines
which took out 25% of the weight by
evaporation. The saving of freight was
about one-fourth. The raise resulted in
shutting down the works at Alameda, the
freight business of the borax company
going to the Santa Fe, as it was cheaper
to ship direct to the refinery in New York.

VENTURA COUNTY.
At Los Angeles on the 9th inst., Judge
Ross in the U. S. Circuit Court gave a de-
cision in the case of the Olive L. & D. Co.
against W. H. Olmstead et al. The suit
was brought to quiet title to oil bearing
lands in this county. The plaintiffs had
secured an order requiring defendants to
show cause why they should not be per-
manently enjoined from boring for oil on
said lands. The decree is entered in favor
of the complainant. The case is import-
ant in that it upholds the rights of those
who hold lands through locations ob-
tained by the use of scrip, which lands are
known as lieu lands. The Court affirms
that the settling upon lands as agricult-
ural claims is sufficient to hold it, even
though others should come along and
oust the-settler by putting up monuments
and laying claim to the land as a mineral
claim. Thousands of acres of land held
by settlers as agricultural land in central
and southern California has been relocated
and is now being held by mineral claim lo-
cators as oil lands. It was almost a fore-
gone conclusion that Judge Ross would
decide as he has. His decision in the case
of the Nevada Sierra Oil Co. vs. Home
Oil Co. last December showed what his
decision in this last case would be. In
both decisions he followed the letter
though not the spirit of the law, and it is
doubtful if his decision would be over-
ruled were the case taken to the appellate
court. This whole question of scrip and
law of title to oil lands was clearly and
ably set forth and discussed in the issues
of April 7, 14 and 21, 1900, the best expo-
sition of this important subject that has
COLORADO.
(Special Correspondence). — The Colo-
rado & Southern, Colorado Midland and
the Rio Grande Western railways are now
operated as one system, each road, how-
ever, maintaining its separate organiza-
tion. The Colorado Midland line runs
from Colorado Springs via Leadville. to
Grand Junction; the Colorado & Southern
reaches out from Denver to the mining
districts of Gilpin, Clear Creek, Boulder,
Park, Summit, Lake and Gunnison
counties, to Colorado Springs, Pueblo and
Trinidad. It reaches Cripple Creek over
the Midland and Midland Terminal. It is
believed a line will be constructed, con-
necting the South Park branch of the
Southern with the Midland, to make a
shorter line between Denver and Cripple
Creek and between Denver and Leadville.
The Rio Grande Western, whose main
line runs from Grand Junction, Colo., to
Ogden, Utah, handles the western busi-
ness not only of the Colorado & Southern-
Midland lines, but that of the Denver &

Mining and Scientific Press.
July 14, 1900.
Rio Grande, the lines of the latter system
reaching such districts as Cripple Creek,
Leadville, Aspen, the San Juan, Gunni-
son, Creede and Trinidad. In general,
the two systems rival each other in the
Arkansas valley, Cripple Creek, Gunni-
son, Aspen and the Trinidad section; and
while Boulder, Gilpin, Clear Creek, the
South Park and the Blue Biver regions
are strictly the territory of the Southern-
Midland combination, the Denver & Rio
Grande is supreme in San Luis valley,
Creede, the San Juan and the lower course
of the Gunnison. The resources of Bio
Blanco and Routt counties are attracting
much attention, great as they are known
to be in mineral and grazing wealth, and
it is not difficult to foresee activity in rail-
road building that will connect that well-
watered section of mountain and valley
with Denver.
Denver, July 4.

CUSTER COUNTY.
(Special Correspondence). — The Geyser
mine, at Silver Cliff, whose shaft is 2650
feet deep, was closed down on the 5th
inst., an assignment having been made to
W. J. Elmendorf. Current debts for labor,
fuel, supplies, etc., amount to $25,000. A
reorganization is looked for, and it is be-
lieved the idleness will be only temporary.
It is claimed nearly $2,000,000 have been
expended on the Geyser. It is also claimed
that good ore has been found at various
depths.

DOLORES COUNTY.
(Special Correspondence). — The Atlantic
Cable group, at Rico, owned by T. Walter
Beam, and under bond to the New Jersey
Zinc Co., is attracting much attention by
reason of ttie discovery thereon of a con-
tact deposit of zinc-lead-copper ore, with
some gold and silver, which is shown to be
40 feet thick where the work is being
done. The ledge is almost horizontal and
is between lime and porphyry. This and
other development give Rico a lively
character.
Rico, July 3.
EAGLE COUNTY.
Near Fulford the Mendota mine is be-
ing developed by the Golden Rule T. &
M. Co. The vein is 12 feet wide, the pay
streak 4 feet thick. The ore assays from
$10 to $27 per ton gold. Within the dolo-
mite is a porphyry dyke. Under this
porphyry and on the top of a lime floor,
or foot wall, is a vein of white quartz and
clay from 2 to 10 feet thick, carrying fine
ore.
FREMONT COUNTY.
The Rocky Mt. Smelting Co. 's plant at

GILPIN COUNTY.
(Special Correspondence). — The 80-
stamp mill of the Boston & Denver M. &
M. Co., erected at Blackhawk by the Hen-
drie & Bolthoff Mfg. & Supply Co., is com-
pleted and in operation. It is near the top
of the Gregory incline and at the terminus
of the car tramway which connects the
mill with the 400-foot level of the Cook
mine, by means of tunnels. The tunnel
entrance is on a level with the crushing
floor of the mill. The ore, as it is deliv-
ered from the cars, passes over grizzlies,
of which there are four, the fine ore sift-
ing throughthe latter and passing direct
to the stamps. The coarse, passing over
the grizzlies, is. reduced to 2J-ineh sizes by
four Blake crushers, run by a 60 H. P.
engine, for this special purpose, which is
set on the third floor. The crushing floor
is 42x66 feet, below which is the distribu-
ting floor, with four bins, from which the
ore is distributed to sixteen bins, ranged
along above the battery floor, there being
one feeder bin to each 5-stamp battery.
The ore feeds from bins to batteries
through Bolthoff automatic feeders. The
line shaft, 6 inches in diameter and 184
feet long, is connected by belt with the
driving pulley of the engine. The cam
shafting is divided into eight sections,
each section connecting with the master
shaft by belt and pulley and operating ten
stamps. By this arrangement any section
of ten stamps may start or stop independ-
ently of the others. Besides, patent fin-
gers are provided, which work by eccen-
trics, by which any stamp may be hung
up. The battery posts are 12x24 inches
and 22 feet long. The stamps are 1000-
pounders, dropping about ninety-five per
minute. The cams are of the Bolthoff
patent, each having, in addition to the
regular type of key, a gib key which
passes through the cam, over the shaft,
pressing down upon the latter, making
the fastening more secure. (See engrav-
ing on front page.)
Below each 5-stamp battery is an amal-
gamating plate of soft copper, superplated
with 2J ozs. of silver to the square foot.
Each plate is 5x18 feet. The material
passes from the sixteen plates to twenty-
four Woodbury concentrators, ranged in
two rows on the lower floor, material from
every two plates discharging upon three
tables. The concentrates will be delivered
into cars for shipment by belt conveyors,
there being one conveyor to each three
tables. It is estimated the capacity of the
mill will be 300 to 350 tons of ore per
twenty-four hours, and will require two
crews of six men each.
The power to run the stamps and con-
centrators is a Standard Sioux Corliss en-
gine, 250 H. P., with cylinder 20 inches
diameter and 42-inch stroke. The fly-
wheel is 15 feet diameter and weighs three
and a half tons ; the driving pulley is 10
feet diameter by 30-inch face. The engine
is provided with latest pattern of valve
gearing, water relief and oiling devices.
The power is derived from four boilers of
100 H. P. each.
Blackhawk, June 19.
At Central the Gettysburg mine is re-
ported to have, at a depth of 50 feet, a
vein of smelting ore 16 inches wide — $50 a
ton — "yellow copper," "white iron " and
"peacock."
The ore shipments of smelting rock and
mill concentrates from the county for
June amounted to 225 cars, or 4590 tons.
LAKE COUNTY.
(Special Correspondence). — The Starr
placer grounds, comprising 35 acres along
California gulch, are reported sold to
C. B. Kountze and associates of Denver.
This is considered very valuable ground.
Much interest at Leadville centers in
the mineral ground lying immediately
under the business portion of the town.
Becent developments in the Home and
other down-town groups make it certain
that the ground under Harrison avenue —
the main business street of the town — has
great mineral value; but this ground be-
longs to the numerous lot owners, because
title passed to them originally without re-
serving mineral rights. Efforts are being
made by various companies to acquire by
purchase or lease sufficient contiguous
ground from the lot owners to warrant
starting mining operations, but the task
is proving slow and difficult. It results,
however, in giving many persons a snug
sum for the underground segments of their
lots which they never counted on.
The original workings in Leadville dis-
trict were in the placer grounds of Cali-
fornia gulch in 1860. Prom that date to
1878 they produced millions of dollars in
gold; and since the discovery of the silver-
lead-carbonate contacts, which made the
camp famous, these placers have been
continuously worked in a small way. A
number of men are working them this
season.
Leadville, July 5.
At Leadville on the 4th were broken
some drilling records. Andregg & Cham-
berlain of Victor drilled 39J-| inches in
Gunnison granite in fifteen minutes ; Rich-
ard Conley of Victor, single-handed, 21 J
inches.
The Miner thinks that a zinc smelter
that could save the zinc and silver values
would be a big dividend earner in Lead-
ville. There are quantities of ore carry-
ing from 5 to 15 ozs. in silver with per-
centages of 10\ to 50% zinc, most of which
at the present time cannot be treated to
advantage on account of the heavy pen-
alties imposed in the ordinary lead smelt-
ers and the loss in values of zinc. The
Miner thinks that could the zinc and sil-
ver values both be saved it would increase
the output of that camp close to 25% in
value.

poration promoted by the Woods Invest-
ment Co., to take over about eighty acres
of mineral ground on Bull hill, in the
neighborhood of the Wild Horse mine,
also owned by the Woods people. It is
given out that the recently acquired tract
was purchased from various parties by the
Woods Co. at a cost of about half a mil-
lion dollars.
Victor, July 9.
For the first half of 1900 Cripple Creek
produced gold to the value of $12,413,070.
Of this, incorporated companies paid
$3,500,000 in dividends.
The Gold Coin mine during June pro-
duced 3600 tons of ore, the greater part of
a smelting grade. The average value of
the ore for 1899 was $46.50.
The monthly tonnage of the Elkton is
about 1100 tons, of an average value of $90
per ton.
A small " rush " is reported from Crip-
ple Creek district to a new find 10 miles
north of Victor and 8 from Pike's
peak, at graders' camp No. 5. It consists
of a vein 2 inches in width containing
fluorspar and talc.

eight-hour law went into operation ; the
mines are beginning to resume their old
rate of shipping. Kaslo is the chief town
of the Ainsworth mining division, but
many of the big Slocan mines also ship
through this port. According to figures
obtained from the customs house, there
are 200 mines under development round-
about. Of these, 90 are foreign shippers
and 30 are paying or have paid dividends.
The amount of dividends paid to date by
the Slocan and Ainsworth mines which
ship through here totals $7,800,000.

Chihuahua Enterprise : If negotiations
now being carried on are successful, Tor-
reon will have two large smelters. One of
these is to be started by Torreon, Saltillo
and Monterey parties with a capital of $2,-
000,000. The establishment of this smelter
at Torreon has been talked of for some
weeks, and now comes another proposition
by R. S. Towne, president Compania Met-
alurgista Mexicana, to erect a smelter at a
cost of $5,000,000.
Six miles from Nacosari, Sonora, the
new smelter is completed at a total cost of
$3,000,000. The railroad from the mines
to the smelter is hauling ore for reduction;
there is enough on the ground to keep the
furnaces busy for two months. Men are
preparing to fire up.
THE KLONDIKE.
The report of R. G. McConnell shows
production as follows:
1897 $ 2,500,000
1898 10,000,000
1899 16,000,000
Total $28,500,000
It is unlikely, Mr. McConnell says, that
the rapid increase in production of the
last two years will be continued, as serious
inroads have already been made on the
rich portions of El Dorado and Bonanza
creeks, and to a less extent on Hunker
and Dominion creeks, but the amounts re-
maining with the long stretches of medium
and low grade gravels still untouched on
all the creeks ensure high production for
a number of years. Bonanza creek is the
most important gold-bearing creek in the
Klondike district. The gravels, however,
have not proved uniform in value, and
stretches occur which have proved too bar-
ren to work under present conditions. The
richest portion extends from Victoria
gulch down stream for about 2 miles. A
number of claims in this stretch, he says,
will yield over half a million dollars each.
Mr. McConnell expresses his opinion that
the placer gold, like the accompanying
gravels, is of local origin, and derived from
the quartz veins and silicified schists of
the district. The large nuggets nearly
always enclose fragments of quartz, and
quartz pebbles specked with gold are oc-
casionally found. A boulder found ou No.
4, Bonanza creek, weighting 60 ozs., con-
tained 20 ozs. of gold. Evidence of the
local origin of the gold is also afforded by
the markedly angular and unworn charac-
ter of the grains and nuggets found in the
gulches and along the upper parts of the
productive creeks. The prospecting of
the past two seasons has resulted in the
staking of a number of quartz claims, but
very little development work has been
done. Prospecting can only be carried on
at present over a small portion of the dis-
trict, as the country rocks are nearly
everywhere concealed beneath a heavy
blanket of moss. Hence free milling gold
mining is as yet a thing of the future in
the Yukon, and only exceptionally high-
grade deposits will there pay, under neces-
sary costly conditions of life and work.

ton, D. C, on the 1st insc, places the gold
output of the Klondike of this year at
$18,000,000. He expects about $10,000,000

information to inquirers.
DR. A. R. Le Doux of New York City
has purchased the right to use the pneu-
matic cyanide process in the cyanide
plant of the Great Northern M. & D. Co.,
at Gilt Edge, Mont., which is considered
the largest cyanide mill in that State.
The Burt Mfg. Co. of Akron, Ohio, last
week made one of the largest shipments
of the year to their London agency. The
demand for Cross oil filters in England,
where they are in competition with a
dozen or so of English filters, is another
indication of the popularity of American
manufactured goods abroad.
The Canton Steel Co. of Canton, Ohio,
from January 1 to July 1, 1900, shipped to
consumers and dealers in the mining sec-
tions of the West and Northwest approxi-
mately 1,000,000 pounds of steel, for use
strictly in connection with the mining in-
dustry, which figures convey some idea of
the largo tonnage of steel required in min-
ing operations.
About 100 Willley concentrators per
month are turned out at the Wilfley shops
in Denver, Colo., where about 120 men are
employod in their manufacture. In the
woodwork white pine is used for the bed-
ding framo and California redwood for the
decks. This shop supplies most of those
which are sold in the United States and
British Columbia, there being shops for
their manufacture in London and Mexico
City.
Fraser & Chalmers, Chicago, report
having received from the Anaconda Cop-
per M. Co. orders for a large amount of ma-
chinery for their new concentrating plant,
which will have a capacity of 4000 tons
per day. This machinery includes twenty-
four heavy-pattern 5-foot Huntington cen-
trifugal roller quartz mills, twenty-four
sets of 40xl6-inch crushing rolls with
forged steel shells, and twenty-four Blake
crushers, sizes 24x12 inches and 15x9
inches.
The Hendrie & Bolthoff Mfg. & Supply
Co. of Denver, Colo., recently furnished a
20x48 Corliss, flat-rope hoist for the Vin-
dicator mine, Cripple Creek district, which
is being installed. A similar hoist will be
furnished the Gold Coin Co., foundation
for which is being laid. This company
also report a new hoist of same style for
the Portland G. M. Co. at Victor, and one
of same size and type for the Elkton mine.
This house is also furnishing a steel gal-
lows-frame for the Elkton.
The Colorado Iron Works, Denver,
Colo., have manufactured and set up
twenty-three smelting furnaces in various
parts of the country within the past year,
there having been about an equal number
each of the lead and copper type. One of
the latest orders was a U-pipe, hot-blast
stove for the Mountain Copper Co., at
Keswick, Cal. This company is now man-
ufacturing Bartlett concentrators at the
rate of fifty per month, and this capacity
will be increased. Numerous changes
have been made in this table within the
last two years, and it is now considered a
table adaptable to all classes of ore. It is
substantially built, weighing 2600 pounds.
"The Spanish war," says E. H. Os-
borne, secretary National Tube Works,
"was the greatest advertisement that
America and American manufacturers
ever got. It was worth millions to us as an
advertisement. Take the battleship Ore-
gon alone. Could anybody doubt, after
the unparalleled performance of that won-
derful ship — 15,000 miles without a nut
having to be 'screwed up — that American
artisans, inventors and manufacturers
know their business ? We made the tubes
of the Oregon, and of the Olympia and
the Monterey. It isn't a bit of wonder to
me that Irving M. Scott of the Union Iron
Works, the builder of these vessels, was
seriously spoken of at Philadelphia as a
possible Vice-Presidential nominee."
The Mine & Smelter Supply Co. of Den-
ver, Colo , are thoroughly testing a new
power drill called the Durkee Lightning
Drill, invented by L. Durkee of Denver,
Colo. It is a mechanical drill, operated
by an electrical motor through a flexible
shaft. Well-known and thoroughly tried
devices are used as far as possible in the
drill. The chuck and rotating devices are
the same as those used in ordinary air
drills, as is also the guide shell with feed-
ing device. Movement is imparted to the
drill rod through a bell crank, the verti-
cal leg of which drives a crosshead which
is loose on the drill rod. The horizontal
leg of the bell crank is slotted, and in this
slot plays a brass on a crank pin.
This crank pin is rotated at about 600
revolutions per minute, and is so placed in
the slot of the bell crank that the upward
motion of the pin draws the drill from the
rock while the bearing is at the outer end
of the bell crank or at the point farthest
from the pivot. This causes the drill' to
be drawn from the rock at comparatively
slow speed, but with greater power,
as the pressure is applied at the
long end of the lever. As the driving
crank rotates farther, the drill rod is
thrown toward the rock by the downward
motion of the crank pin at a point nearer
the pivot, which causes a very rapid
movement of the drill, the movement
being at its maximum velocity near the
end of the stroke. The forward motion
of the drill against the rock occupies about
one-third the time that the backward mo-
tion requires. The crosshead on the rod
gives motion to tho drill rod through a

strong buffer spring which bears against
a collar on the drill rod. As the cross-
head draws the drill backward it also
operates through a second spring against
a second collar on the rod. Buffer springs
are also provided to relieve the machine
when the drill does not strike the rock.
The simplicity of the drill commends
itself to the observer and tests thus far
have been satisfactory.

Surgical Pad.— No. 652,889. Dated
July 3, 1900. Tillie Campbell, M. D., Oak-
land, Cal. This invention relates to a pad
which is especially designed for obstetri-
cal and surgical operations. It consists
of a base having a surrounding hollow
rim, with means for supplying hot water
to fill and warm the apparatus, a drainage
canal connecting with the front, and longi-
tudinally disposed seams with intermedi-
ate ridges which form independent drain-
age channels to conduct away any liquid
to the drainage canal. This seems to an-
swer the double purpose of preventing the
central part from rising up like a cushion,
and also to form drainage channels con-
necting with the single receiver and dis-
charge tube. Exit passages discharge the
water from the pad, and it may be gradu-
ally discharged, while a new supply is ad-
mitted from the fountain.
Fuel Economizer. — No. 652,895.
Dated July 3, 1900. J. H. Hobart, El
Paso, Texas ; one-half assigned to E. R.
Phillips of same place. The object of this
invention is to provide a device which is
especially adapted for economizing in the
combustion of fuel, especially where used
in conjunction with steam boilers of any
description. The firebox of the boiler has.
an arch fitted in the upper part, with an
internal chamber, and a wall built up from
he lower part of the firebox forms the
leat passage between itself and the arch
bove. Passages are made in the wall and
onneetions from the firebox, with means
for connecting the passages with the
chamber of the arch, and means connect-
ing said chamber with the heat passage
between the arch and the wall. Trans-
verse water pipes have their ends con-
nected directly with the water legs of the
firebox, and serve to support the arch.
Regulating Devices for Riding
Carts.— No. 652,882. Dated July 3, 1900.
Y. H. Boudreau, Modesto, Cal. This in-
vention is designed to relieve the disagree-
able movements of two-wheeled carts,
which are drawn by a single horse, and to
prevent the jerk caused by sudden start-
ing or stopping of the animal, and also to
reduce the tilting of the cart body in go-
ing up or down hill. It comprises a bent
or crank axle, upon the central portion of
which the vehicle body is supported, the
upwardly and outwardly turned ends
forming the wheel spindles. Clips are
fixed to the axles between the wheel spin-
dles and the crank portion, and fulcrum
pins extending through the upper parts
of the clips support the shaft by which
the vehicle is drawn. Rigid bars are
clipped beneath the axle extending paral-
lel to and beneath the shafts, and springs
are clipped between the axle and these
rigid bars, having their ends upturned to
form elastic contacts with the lower part
of the shafts on each side of the axle.
Plates are hinged beneath the shafts and
form connections between the shafts and
the spring ends.
Portable Conveyor and Eleva-
tor.—No. 652,911. Dated July 3, 1900.
Geo. E. Bowers, San Francisco, Cal. The
object of this invention is to provide a de-
vice which is designed for transporting
and elevating earth from excavations or
pits such as are made in the construction
of buildings, whereby the earth to be re-
moved is conveyed from any point in the
excavation to the elevator, by which it is
afterwards raised to the level of the street
or other point of deposit. The mechanism
is so contrived that by means of a hori-
zontal carrier, which may be elevated or
depressed, the earth can be transported to
a point where it is received upon an in-
clined elevator, which conveys it to a suf-
ficient height to be discharged through a
chute into wagons or other places of de-
posit. This second elevator is also so
mounted with relation to the first that it
can be adjusted to accommodate itself to
the movements of the horizontal elevator.

I I THREE ROLLER
ORE TWILL. I
The Ciritlin Throe Roller Ore Mill is a simji.y i-uiistrucUid Mill, suitublu fur wen-king all kiuds of ores that
require uniformly fino crushing by tho wet process. This Mill is a modification of the well-known Chilian
Mill, but tho rollers run upon a crushing ring or die, which is inclined inwardly at an angle of about 30 degrees,
the rollers themsolveS also being inclined to the central shaft of the Mill, thus utilizing the centrifugal force,
as well as the weight of the rollers themselves as a crushing agent. ThoGritlin Three Roller Ore Mill is there-
fore a Mill of great strength, and has few wearing parts. We construct these Mills with extreme care, using
only the host of raw materials, which are most carefully worked by men who are specialists as mill builders.
We sell the Griffin Oro Mill on its determined merits, and will gladly supply full information regardingit to
any one.

We build furnaces to drawings and specifications, and furnish drawings and full instructions for erecting.
We erect all furnaces at our works and oarefully mark every piece before shipping. By this means, trouble in ereoting at
the smelting plant is entirely avoided.
We contract to build and equip smelting plants complete, of any required tonnage oapaoity above forty tons per day, at
any desired location and put them into successful operation under guarantee. We contraot to smelt a thousand tons of ore, more
or less, before turning the plant over as completed under the guarantee
We have in the past built more Blast Furnaces for smelting the ores of the valuable and the precious metals— gold, silver,
lead and copper— than any other manufacturing concern on the American continent, and in the past year of 1899 we built more
such furnaces than all others combined.

" Empire, Colo. : The success achieved by the Cammett
tables in handling the ore from the Maud S. mine, an ore es-
pecially difficult to concentrate on account of the great
variety of its metallic contents, has given the Bonaccord mill
a reputation that will firmly establish it as a safe plant for general

THE UTTUE ALASKA GOLD WASHER.
After several yearB' practical
use in different fields, our
washer has established its
superiority over all placer or
beach washers. It is just the
washer for Cape Nome; it was
used extensively in Alaska
last year with every success.
In working the operator does
not have to wet his hands and
can stand in an upright
natural position. It is
just the washer for the
poor man who has not
the money to put In ex-
pensive machinery. It
will do the work of ten
men with gold pans. It
is just the washer for
the prospector, being
light and easy to pack.

THE BROWNELL "PATENT LIP" FLANGE FRUE VANNER BELTS.
It has taken years of ceaseless testing and experimenting to produce the superior belt which
we now offer, with elastic flanges and pliable body reinforced with specially woven duck. Every
belt is manufactured by experienced workmen, and carefully tested on machines especially built

A New Phase of an Old Industry.
In preceding issues has been noted the advance in
lighting, railways, power transmission, telegraphy,
telephony and other forms of electric appliance. The
subject of telpherage deserves passing notice.
Telpherage is described as being automatic aerial
transportation by the aid of electricity, especially
that system in which carriages having independent
motors are run on a stout wire conducting an elec-
tric current from which the motive power is derived.
Telpherage is a name coined by the late Fleeming
Jenkin to designate a system devised by him by which
and rapidity of operation which depends on the speed
of the electric car is only limited within reason by the
cost of construction, the length of the line from one
station being only bounded by the commercial possi-
bilities of electrical transmission. Curves are not
considered a disadvantage any more than in the sur-
face electric railways, and the direction of route may
be changed as often as desired to avoid excessive
grades and thereby cheapen the cost of construc-
tion.
Regarding this the Consolidated Telpherage Co. of
New York City say that the cost of the line and roll-
ing stock is small and the power required can be
by turning a switch, and within a short distance the
speed can be accelerated up to 50 miles an hour if
required, though such a speed, considering the loads
which can be carried, would rarely ever be neces-
sary, a speed from 20 to 35 miles per hour fulfilling
most conditions of service. The system is so arranged
that branch lines can feed into one main trunk line,
and each car is so controlled that no two ears can
come in collision. In case one car should be traveling
the main track and another car should be approach-
ing from a branch or side track to go upon the main
track, the second car will stop and wait for the first
car to pass on some distance ahead on the main track

the transmission of vehicles by electricity to a distance
is effected independently of any control exercised
from the vehicle. It is an aerial electrical railway.
This, then, is a new phase of an old industry, the
application of electricity to the existing principle of
aerial wire ropeways, now becoming so deservedly
common wherever mining or manufacturing is car-
ried on in a large way. This is but one of the classes
into which telpherage is divided. There are also sys-
tems of telpherage in which are what may be styled
electric tube dispatch, either overhead, surface or
underground ; . electric overhead tramrail, by rigidly
supported girders ; automatic narrow gauge railway.
The main object of telpherage is to provide auto-
matic methods, by the use of electricity, for quick,
economical transportation of mail, express, freight
and other light material. In aerial telpherage it is
- ot necessary to follow' the contour of the country,
rented from any existing electric lighting or railway
plant. The electric tube dispatch is another branch of
telpherage and consists in sending merchandise, mail
and express through tubes which are either under-
ground or at the surface. These tubes are con-
structed of various substances, depending upon local
conditions, in some cases watertight pipes of vitri-
fied clay and like material, and in others tubes of
structural iron, the diameter of the tubes varying
according to the amount and character of material
to be carried within a certain time. The cars run
upon steel rails of special form in the tubes, and the
cars and rails are of sufficient rigidity and strength
to carry merchandise and second-class mail matter.
The cars are so arranged as to be operated individu-
ally or in trains, depending upon the amount of mer-
chandise required to be sent in a definite period.
The system is wholly automatic. The car is started
before starting. This is done automatically. Any
car can be arranged to stop at any station upon its
route, this being determined before the car leaves
the starting station. Cars can also be adjusted so
as to take either the left or right hand tracks and
thus to make communication with any sub-station.
The track can be made single or double, depending
upon the number of tons to be transported daily. A
complete block system prevents collisions.
The company mentioned claims to have worked the
details of its system out completely and tried them in
practical operation. In certain cases their success
has been due to the development of the art in general
and to the great advances made in electricity, for
successful telpherage a few years ago would have
been impossible. Existing conditions and require-
ments make the subject one of practical interest to
mining men everywhere.

Lead Tariff, Prices and Supply.
The ups and downs of the lead market are so fre-
quent and confusing as to make it difficult of under-
standing, recent fluctuations showing a difference in
current rates of nearly $20 per ton. Much has been
said on this important subject, and the multitude of
the interests it involves justifies continued mention. A
statement of previous and existing facts from an in-
dependent standpoint is of present interest. Every
one directly or indirectly interested in this subject is
presumably acquainted with most of the general facts
in connection with the present situation. Probably
no part of the metal mining productive world pre-
sents so complex an appearance as the present condi-
tion of the lead market in the United States, where
the trusts, the tariff and the law of supply and de-
mand are the principal factors in the price, each
trending back many years, anticipating and creating
present conditions.
In 1861 the Morrill tariff bill admitted gold and sil-
ver into this country free, the desire then being to
get specie to meet Government obligations. A ship-
load of silver-lead ore arriving occasioned a Treasury
Department ruling that, under that tariff, if the value
of the silver or gold combined in the ores exceeded
the value of the lead therein the whole product should
come in free. This west half of America was sparsely
settled in those days ; mines of any kind were few out-
side of California, and lead miners fewer still ; but in
the early '70s lead became a prominent production
east of the Sierras, and an ore-producing association
was organized in Utah, which, among other things,
fought against free lead. They protested and peti-
tioned Congress for an import duty in about the same
fashion that the California Miners' Association has
fought for a Mineral Lands bill, and their representa-
tives at Washington found many of their protests and
letters pigeon-holed, but they kept the fight up and
finally got notification from the Treasury Depart-
ment that they should be granted a hearing — the first
of the kind — which was given them in May, 1889. The
smelter men of Kansas City and other places wanted
the Mexican lead ores to come in free, which was good
business from their standpoint, though injurious to
the lead producers of the West from their standpoint.
The latter won their point, and the Government ruled
that thereafter the lead in the ores should be taxed,
and appointed an officer to be stationed at El Paso
to sample the lead ores from Mexico on the border.
The Utah lead producers started to get out lead at a
better price, and the smelters started to fill cars
nearly full with heavy lead ores, and to pile upon the
top of the ores very rich silver ores with a little lead,
get that ore sampled, the cars run across the Rio
Grande, the rich ores saved and sent back, the heavy
lead ores unloaded, the former thus convoying the
latter, until John Tiernan was sent by the Utah Lead
Ore Producing Association to investigate, going as
an ostensible buyer of hides, and after unearthing the
subterfuge succeeded in having it stopped. The next
movement on the part of the smelters was to secure a
Government ruling that, from the samples assayed,
10% should be stricken off as a smelter loss, and 10%
more as a loss in refining. The Utah Ore Producers'
Association made demonstration, by their El Paso
representative, that the total loss in the smelting did
not exceed 4% and that the loss in the refining did
not exceed 1%. After that was blocked the smelters
got a ruling from the Treasury Department permit-
ting ores to be run into bonded warehouses and held
six months. How this worked, in their behalf, can be
estimated from the fact that the chairman of the Bu-
reau of Statistics for the United States Treasury
Department, in 1898, made official report that
twenty-one million pounds of lead had been entered
that could not be accounted for. In 1898 the smelters
secured another ruling which permitted them to ac-
count for only 90% of the ore received, and another
ruling permitting lead ore to come in free in the slag,
in that way " slag " coming in carrying 85% metallic
lead. This was ruled out by the Treasury Depart-
ment, but just two years ago the smelters secured
another Government ruling permitting lead in copper
matte, where the copper was worth more than the
lead, to come in free. This the Utah Ore Producing
Association fought to final appeal. None of the above
applies to Pacific coast smelters.
All this is merely instanced as a matter of record,
to illustrate that while a tariff is a very simple thing
it is sometimes difficult to enforce it according to its
spirit and intent. The duty on lead in the ore is \\
cents per pound.
At $4 per 100 pounds there is not much profit in
lead mining. There would be still less but for the
tariff of $1.50 per 100 pounds. With that tariff off,
lead would sell at about the same price in the United
States as abroad, except for fluctuations due to vari-
able local demand. It would sell at the present price
less $1.50 per 100 pounds. At that price nearly every
lead mine in Idaho, Montana, Utah and Colorado
would be compelled to idleness. The shutting down of
those mines would mean ruin to many.
It is probably an underestimate rather than an ex-
aggeration to say that the tariff on lead has given to
the miners of the one State of Utah in a year one
million dollars more than they would have received
without that tariff on the lead in the ores, and that
that amount represents but a part of what the tariff
is worth to them or to the miners of Montana, Idaho,
Nevada,. Colorado, or anywhere else where lead is
mined in the States producing gold and silver, for
much of this gold and silver comes as part of the
product, the great production of lead increasing the
amount of the latter. Utah is particularly mentioned
as it produces about fifty thousand tons of lead an-
nually, though Idaho, Montana and Colorado are al-
most equally interested, so that the cry against the
tariff on lead in the ore is suicidal.
It will be seen that in one sense it would be to the
interest of the smelters to have lead free, while it is
equally manifest that if they can so manipulate the
tariff on lead as to make it inure both ways to their
advantage, it would be particularly gratifying in a
pecuniary sense to them. The situation is a complex
one. The smelters having failed in their effort to
have the tariff so construed, the American Smelting
& Refining Co. has been formed, which, as a business
proposition, is precisely in the line of modern advance
and is just what any other industry so situated would
do. It is manifest that this latest consolidation of the
lead manipulators has entire control of the price and
can raise or depress it as best determined by their
immediate or transient interests. All this is entirely
from the unbiased and impartial standpoint of this
paper, having nothing to do with private interests
nor politics, the matter being discussed from a thor-
oughly independent standpoint.
The recent effort of the principal lead producers to
aid in the maintenance of good prices for the raw
product seems stultified by the fact that they appear
to be necessarily co-operative with the American
Smelting & Refining Co., who seem to have in every
way the best of it, as probably it is only by increasing
their export trade that the American Smelting & Re-
fining Co. can get better prices at home and thus pay
the producers more for their ore. The duty on lead
being 2J cents per pound precludes any importation
and cuts little figure in the case. There is little
justly bearing upon the subject in the statements
made and the hurried conclusions drawn in some dis-
cussions of this subject regarding lower prices of lead
in the foreign market as compared with the domestic
markets, the fact being clear that were it not for the
tariff on lead, even its present price in this country
could not be maintained. In the light of the events of
the past few weeks and the extraordinary fluctua-
tions of the lead market, it is difficult to predicate
how any co-operative efforts by part of the miners
and the American Smelting & Refining Co. can be
successful. This brings us to the discussion of the
last factor in the situation, usually the most impor-
tant, namely, the law of supply and demand, a law
which does not have full force and effect in this case,
being sumptuarily interfered with by the position
capable of being maintained by the American Smelt-
ing & Refining Co., with whom, by reason of all these
facts, rests the responsibility for results.
The producers have for some time been endeavor-
ing to make a combination that would set some stable
quotations, some figure that could be held to, and
several meetings gave color to the belief that prog-
ress was being made in that direction. The difficul-
ties in the way were so obvious throughout that little
hope was generally entertained that the effort would
result successfully. A sort of minor agreement was
had with the American Smelting & Refining Co.,
conditioned on the ability to have general agreement,
and about the 1st inst. it looked as though such gen-
eral co-operation were possible, but the Missouri
lead producers have declined to go into any combine,
thus deferring what from the start did not look like a
hopeful project. Of course, at long last the producers
have the strength of the game — that is, were it to
come to a final trial of strength between those who
produce the ore and those who handle and sell it, if
the former unanimously declined to furnish the prod-
uct it would leave the latter without anything to do
business with. The difficulty of making and main-
taining a combination among the producers is mani-
fest. The situation is an untoward one and affects all
alike, though existing conditions on the Pacific coast
do not include any smelter west of the Sierras in the
monopoly of the trust. It looks as though there
would be a fight and a desperate one, and that mean-
while lead has not reached its lowest point ; when it
does the purchasers will be heard from in more unani-
mous vigor than before. The present situation is
this : the trust proposes to buy up surplus lead and
export it, to keep the surplus down and the home
price up, if the producers meanwhile will stand the
loss. Missouri lead producers decline to become a
party to such compact.
The Secretary of the Interior, in a decision in a
case involving the location of mineral claims in Crip-
ple Creek, Colo., has overturned all former decisions
in which it has been held that a deputy mineral sur-
veyor could not locate claims for mineral lands, on
the ground that he is a United States officer and that
such location by him would be in violation of that
section of the Revised Statutes which forbids ' ' of-
ficers, clerks and employes " of the Land Department
from making entries. W. H. Leffingwell made en-
tries in December, 1897, for three groups of claims.
After the entries were made the Land Department re-
fused to issue patents and held the entries invalid, for
the reason stated above. The decision was rendered
in September, 1899. In this last opinion it is held
that the section of the Revised Statutes heretofore
quoted does not apply to mineral land surveyors, in-
asmuch as they are not employes of the Government
within the meaning of the law, and they can make en-
tries for mineral lands and receive patents therefor.
This applies to mineral land surveyors everywhere.
The progress and development of the mineral in-
dustry of this west half of America is phenomenal.
It is not uncommon in this office to receive copies of

The weekly market quotations of lead in London are

The test of any form of mineral analysis is its com-

Wm. Thompson, or Lord Kelvin, is doubtless the

It may be that S. J. Carrigan of Northfield, Minn.,
has discovered the existence of three hitherto unknown
planets between our earth and the sun, "each of which
is heading for us and sure to destroy this planet," but
the fact is not generally known. It really, however,
makes little difference. Probably if this planet were
totally destroyed we could all get along just as well with-
out it.
Ik at atmospheric pressure the temperature of the

A OOOD substitute for German silver is an alloy of cop-

silver.
An ink that can be used for writing on glass is pre-
pared as follows: To 20 grammos of brown shellac dis-
solved in 150 cubic centimeters of lamp spirit add a solu-

distilled water. Add 1 gramme of methyl violet for
coloring.
Cryolite is a double fluoride of aluminum and
sodium. It is not of common occurrence. There is a
large deposit in Greenland, and it has recently been re-
ported to exist in commercial quantity on the south
flank of Pike's Peak, Colorado. It is used in the manu-
facture of alum and alumina.
A statement in last Saturday's issue that celestine
(strontium sulphate) is not found west of the Rockies
needs correction. It is found at Glen Eyrie, in Colorado,

found in Plumas county, Cal.
The gold-dissolving power of a solution of potassium
zinc cyanide increases with increased excess of oxygen,
and with rise of temperature, and also by addition of
caustic alkali, other conditions remaining the same, such

A bubbek stamp on a tracing can be reproduced on
a blue print. Make the impression of the stamp on the
tracing linen, and while the ink is still moist dust it over

The safety valve of a boiler may become coated with
lime, even though the boiler does not foam, by small
particles being lifted and blown through when the safety
valve blows off. The space just above the water line in
active service is filled with a sort of water mist, raised by
the liberation of steam below the surface.
A blast furnace for lead smelting has been used for
many years at Freiberg. The latest account received
states that the furnace diameter is increased to 61 feet
and the number of tuyeres to twenty, with the result of
output increased from 10% to 38%, a lessened fuel con-
sumption and a reduction of blast pressure.
A soldering fluid that will not rust nor corrode
may be made as follows : To four pounds hydrochloric
acid add four pounds zinc shavings or cuttings. To the
saturated solution add a small quantity of oxide to color,
and filter through a piece of suitable cloth ; then add one
pound strong liquid ammonia ; stir, and bottle.
Glass has been used as a flux for cyanide slimes in
both plumbago and clay-liner crucibles, in the propor-
tion of 100 pounds roasted slimes (not acid treated), 50
pounds ground white glass and 50 pounds borax. M. T.
Dixon says that this mixture in a clay-liner pot will give
gold 860 fine if treated in a fairly quick furnace.
The tensile strength of the steel from which a boiler
is made is found by pulling a carefully measured bar in a
machine which weighs the load required to break the
bar. The tensile strength per square inch is found by
dividing the total load required to break the bar by the
area of its cross-section in square inches before breaking.
The degree of cold on high Sierra peaks is a
matter of record. A self-recording thermometer was
left on the summit of Mt. Lyell, 13,041 feet high, during
the winter of 1897-98, so placed as to be free from snow.
The lowest temperature reached was 13.6° below zero. In
the winter of 1898-99 the experiment was repeated,
and the record when read the following summer showed
17.6° below.
Compressed air has been applied to the pumping of
water, the power supplied by a gas engine, which drives
an air compressor, the discharge of which is led alter-
nately to two closed vessels. During the time that the
air is being forced into one of them the other is being
filled with water, which is in turn forced out by chang-
ing over the flow of the compressed air, the change being
made automatically.
Foundrymen in a big way find it economy to employ
the services of a chemist to insure a uniform character
of the iron used. Where large quantities are used the
idea in many instances is to keep on hand a stock from
which to supply a mixture which will not exceed .09 sul-
phur and not fall below 2.75 in silicon, nor below 3.25 for
total carbon ; phosphorus, say from .60 to 1.10; manga-
nese, from .40 to 1.00.
Consul Hughes sends the following from Coburg:
" A. Reis of Antwerp has patented the following method
for preventing incrustation in boilers: A mixture of
sugar, tannin extract, silicate of potash or soda and boric
acid is added to the boiler water to keep the salts in solu-
tion; when the water attains a density of about 15 to 25
Be, the boiler is blown off. The working periods range
from a fortnight to throe months, according to the qual-
ity of the water in use. Glycerine and alkaline sulphates
are sometimes used in the mixture."
A cement for stopping leaks in steam pipes was given
in tho issue of Feb. 10, 1900. A Lead, S. D„ correspond-
ent says a manganese cement is in some respects better.
It is composed of four parts black manganic oxide,
ten parts litharge, five parts red lead, five parts unburnt
limestone and five parts yellow ocher. Pulverize, mix
well, knead into dough, add a little boiled linseed oil and
asbestos fiber.
Extralateral rights of lode locations wore incor-
porated in the mining laws of the province of British
Columbia for eight years and abandoned, tho results
tending to disprove the idea that the nature of the Pa-
cific coast mineral deposits requires the grant of the
extralateral right to mining locations. This extralateral
right exists only in the United States and Bolivia, and i9
a heavy expense and incubus.
A telescope can be used with a photographer's
camera to take a picture of an object far off, but the re-
sult is rarely satisfactory; to arrange for the picture the
eye piece of the telescope and the lens of the camera
should bo taken out, and then fit the opening into
camera where the lens was upon the end of the telescope
where the eye piece was, thus making the object lens of
the telescope the camera lens.
An applicant at a U. S. land office to secure timber
land must swear to a non-mineral affidavit. He must
take oath that he knows the conditions of the land at
that time by personal observation ; that the land is not
occupied by any person or persons ; that there are no
mining claims, lodes or mineral deposits, to his knowl-
edge, on said land. Coal, salines and coal oil claims on a
tract of land exclude it from»entry as timber land.
In addition to the "long ton," the "short ton" and
the " metric ton " of metallic commerce is the " shipping
ton " of pig iron, which contains 2268 pounds. That
weight, though obsolescent, is still allowed by railroads
as a weight in shipping iron. The shipper who forwards
100 tons of pig iron is entitled to load 226,800 pounds on
his cars. The extra 28 pounds in the pig iron ton over
the long ton is to allow for sand adhering to the metal.
Turquoise in this country comes mainly from New
Mexico, whose mines were elaborately illustrated and
described in the issue of March 6, 1897. Recently tur-
quoise of value was reported from Mojave county, Ariz-
zona, and also from Lincoln county, Nevada, where
stones of marketable value are reported to have bean
found in mica schist at the foot of Sugar Loaf peak,
some of the specimens weighing from thirty to sixty
carats.
Strontium sulphide is thus prepared : An inti-
mate mixture of 285 g. of commercial strontium carbon-
ate, 62 g. flowers of sulphur, 4 g. crystallized sodium car-
bonate, 2.5 g. salt, 0.4 g. bismuth subnitrate is placed in
a crucible, covered with a layer of coarsely powdered
starch, and submitted for five hours to a bright red
heat, then allowed to cool very slowly for one hour.
This results in a white, friable mass with phosphores-
cent power.
"A 10% grade" means a rise (or fall) of 10 units of
length in a distance of 100 of the same units of length,
the rise (or fall) being measured vertically, and the dis-
tance horizontally. If the unit of length is 1 foot, a 10%
grade means a rise (or fall) of 10 feet in 100 feet ; in the
same way it may mean a rise (or fall) of 10 rods in 100
rods, or 10 miles in 100 miles. A 10% grade in feet to the
mile would be a vertical rise (or fall) of 528 feet in each
mile of horizontal distance.
In a submarine electro-contact mine the firing pins on
the case containing the explosive, instead of exploding
the charge when brought in contact with an object, act
as a switch by closing one opening in an electric circuit.
Another switch is located in this same circuit at a station
on shore, so that in order to fire the mine it is necessary
to close the land switch at the same time that one of the
pins has been driven in by the hull of a vessel. If this
is not done, no explosion takes place.
The electrical conductivity of aluminum is 63% that of
copper. The weight of copper is 3.33 times that of an
equal volume of aluminum. The Standard Electric Co.
of San Francisco have been making extensive experi-
ments as to the tensile strength and general availability
of aluminum for long distance transmission, and can
doubtless furnish practical data. The longest continu-
ous copper wire in use, so far as "Concentrates " knows,
is the telegraph line of the Canadian Pacific Railway Co.
from Montreal to Vancouver — 2,897 miles.
Rawhide rope has great flexibility and, having com-
paratively few strands, is able to stand internal and ex-
ternal friction, as there no small yarns to chafe and
break. Its most frequent use is for dynamo drives and
where small sheaves are necessary. Its great elasticity
causes considerable whipping and it is difficult to make a
splice hold. Its first cost is considerably more than that
of manila. Under ordinary circumstances and condi-
tions, at a speed of 2500 feet per minute 1-inch rope will
satisfactorily transmit 12 H. P. ; lj-inch rope, 26 H. P.,
and 2 inch rope, 48 H. P. The durability of the rope
must be kept in sight as well as the actual transmitting
power. The average life of ropes of medium size is about
four years, though small ropes under unfavorable condi-
tions have to be renewed annually.

The Terlingua Quicksilver flining
District, Brewster Co., Texas.
m>
Written for the Mining and Scientific Press
by H. W. Turner.
The Terlingua district lies about 68 miles in an air
line southwest of Marathon, which is the nearest
point on the Southern Pacific Railroad. By the pres-
ent wagon road it is about 85 miles from Marathon,
but this road can be made about 10 miles shorter at
small expense. The mines are on the mesa west of
Terlingua creek and are in a Cretaceous formation,
called by Prof. Robert T. Hill of the United States
Geological Survey the Caprina limestone. All of the
cinnabar deposits so far as exposed are in this lime-
stone. Whether or not the deposits will be found in
the beds underlying the limestone is at present a mat-
ter of pure speculation, which can be .determined only
by future mining operations. Since the thickness of
the limestone by the Rio Grande about 11 miles south
of the mines is 1500 feet or more, it is probably that
ter of the lode is plainly due to the grinding up of the
rock between the walls during movements. Such
brecciated fault zones form a ready avenue for solu-
tions to rise from depths, and strengthens the as-
sumption that the ore bodies would continue probably
through the entire thickness of the Caprina lime-
stone.
In the ease of the small, irregular rusty veins,
found at many points in the mineralized zone, it is
quite likely that they will not extend with a definite
dip to any great depth, although it is probable that
these subsidiary irregular veins will be found at all
depths through the limestone, but that they will be
disconnected, or prove to be stringers from larger
veins.
Prof W. P. Blake* has published the only satisfac-
tory account of this new district. Prof. Blake noted
pyrite in one of the lodes in addition to cinnabar and
iron oxide, and interpreted the ferruginous breccia,
forming portions of the lodes, as indicative of fissures
along fault planes.
The difficulty in developing the district lies in the
scarcity of wood and' water. However, reservoirs
can easily be built in the rocky ravines, the lime-
Quicksilver Retort at Terlingua, Texas.
thick at the mines, as it is the very top of the forma-
tion in which the ore is now found. Up to the pres-
ent time nearly all of the ore has come from surface
workings, or shallow shafts, and the size of the ore
bodies in depth and the depth to which they will ex-
tend is another point to be determined by mining
operations. It is certain, however, that the cinna-
bar comes from below — undoubtedly from a source
beneath the limestone — and it is therefore more than
probable that ore bodies will be found to a depth of
more than 1000 feet, with a good chance of their ex-
tending still deeper.
The cinnabar mines lie in a limited area about 2
miles wide by 4 miles long, but it is probable that
the mineralized area is of greater extent — at least 3
miles wide by 5 miles long. The general trend of the
main lodes is in an easterly and westerly direction.
The quicksilver occurs in limited amount in the native
form, but chiefly as the red sulphide of quicksilver or
cinnabar. The limestone formation of the district
contains numerous rusty brown veins. These, as
above noted, usually trend in an easterly and west-
erly direction, but many of the smaller veins are ex-
tremely irregular and strike in all directions. These
rusty brown veins are composed of calcite or crys-
tallized carbonate of lime and oxide of iron, usually
enclosing fragments of broken up limestone. Many of
them show walls with striated and smooth surfaces,
showing that movements have taken place along the
walls, as is usually the case along mineralized lodes.
In these veins or lodes the cinnabar occurs in string-
ers or pockets. Many of the veins show no trace of
mercury, and even when cinnabar is present it often
can not be seen on the weathered surface until the
rock is broken, as it is black or otherwise discolored.
The thorough prospecting of the veins is therefore a
matter of time.
In addition to cinnabar, mercury occurs in the na-
tive form — notably in the McKinley lode — and as a
white coating and as yellow-green crystals. Prof.
S. L. Penfield has identified the white coating as
calomel or mercury chloride (Hg2 Cl3), and the green-
ish crystals as an oxychloride of mercury, forming a
new mineral species, for which I have suggested the
name terlinguaite. In tunneling in on the vein of the
Croesus claim, a vertical cavity in the limestone was
found, perhaps 50 feet in depth, lined by a dazzling
white layer of saccharoidal crystalline gypsum, asso-
ciated with some cinnabar. Calcite is present in
nearly all of the brecciated lodes as veinlets, and it
also lines cavities when it is often finely crystallized ;
occasionally seams of it are colored nearly black by
manganese.
There can be no doubt that the so-called lodes are
formed along fault zones. This is particularly evident
with the larger lodes, where the brecciated charac-
stone being suitable for burning lime for cement,
as well as for building dams. The chief firewood is
mesquite.
About 1000 flasks of quicksilver have thus far been
produced, this amount having been reduced in five
retorts. One of the companies is now putting up a
furnace, and the production next year will undoubt-
edly be large.

New Steel Syndicate.
The Crucible Steel Co. of America is the name
of the new steel syndicate just organized at Pitts-
burg, Pa. It is the outgrowth of a consolidation
scheme which was promoted by the Union Trust Co.
of the city named. The capital stock issue is $50,000,-
000, being one-half preferred and one-half common
stock. The new company proposes to take over the
plants and assets of thirteen steel concerns at the
aggregate purchase price of $19,000,000, the plants
and equipment to be paid for in stock in the new con-
cern, the material on hand to be paid for in cash.
The following are the names of the steel concerns to
be absorbed by the new syndicate : Park Steel Co. ,
Pittsburg; Singer, Nimick & Co., Pittsburg; Howe,
Brown & Co., Pittsburg ; Crescent Steel Co., Pitts-
burg; La Belle Steele Co., Alleghany, Pa.; Ander-M>
son, P/u Puy & Co., McKee's Rock, Pa. ; Cumberland
Steel & Tin Plate Co., Cumberland, Md. ; Burgess
Steel & Iron Works, Portsmouth, O. ; Benjamin
Atha and Illingworth, New Jersey ; Spalding & Jen-
nings Co., New Jersey ; Sanderson Bros. Steel Co.,
Jersey City ; Beaver Palls Steel Co. , Pennsylvania ;
Aliquippa Steel Co., Pennsylvania. The new com-
pany was organized under the laws of New Jersey,
but is to have its home office in Pittsburg.
The consolidated concerns belong in the main to that
class of steel makers who are furnishers of drill and
crucible tool steel and such stock as is usually used
in shops that make mining machinery. Many of them
do other classes of work, but the above constitutes a
leading feature. This is mentioned by way of dis-
tinguishing them from such as the Carnegie and
Bethlehem Works, which make a specialty of Harvey-
ized armor plate, heavy shafting, structural work
and ordnance material ; and from the Illinois Steel
Co. and the Colorado Fuel & Iron Co. , whose great
specialties are material for railway equipment and
steel structures.
World's Production of Copper.
The following from official and private statistics
shows how completely North America surpasses
other countries in the production of copper. It
shows, also, that the production is hardly equal to
the demand, for, in spite of increased prices, produc-
tion in 1899 advanced only 9% over 1898 :
1898— Tons. 1899— Tons.

The great denudation of the Colorado river, carv-
ing out of rock a series of canyons about 500 miles
long, in one place more than a mile deep, with a
multitude of tributary chasms and gorges, is held by
some to be due to the slow rising of an ancient lake
bed. At first the Colorado river and its tributaries,
or some nameless ancestor of these, sweeping over
the slowly rising surfaces, planed them down in most
relentless fashion, and then began wearing out broad,
shallow stream beds. But the country rose more
rapidly, and the water had to cut deeper channels in

The Pan-American Exposition.
The greatest industrial display on this side of
the world for some years will be the Pan-American
Exposition to open in Buffalo, N. Y., in the early
part of next year— the first of the twentieth
latest and best achievements of the civilization of the
Western Hemisphere.
So vast is the number of valuable and Interesting
objects for exhibition in the possession of the
United States Government that none but a building
of great proportions could possibly contain them.
Instead of one building, however, at the Pan-
American, the Federal group will consist of three
massive structures connected by colonnades. The
main building of this splendid architectural triad will
be 130 feet wide and (iOO feet long. The others will
each be 150 feet square.
The Stadium, or amphitheater, will have a quarter-
mile track, and a sufficiently large space inside
of this for any of the athletic games. There are
provided seven exits, of sufficient breadth and height
to admit, in case of need, the largest vehicles or
floats, as it is proposed to use the Stadium for cer-
tain pageants, exhibits of automobiles in opera-
tion, etc.

in the affair is the promotion of mutual feeling
and interests throughout the countries of the
American continents by joint participation in a
grand display of the products of all honorable
activities.
The effort has received the full sanction of
this Government, and it becomes, therefore, a
national invitation from the United States to
all other American States. There is every indica-
tion that the undertaking will be strikingly success-
ful, and the preparations now rapidly advancing are
upon a grand scale. The grounds cover 350 acres
and the site is pronounced by landscape architects to
be among the most beautiful in the world. There will
be erected more than twenty large buildings and
massive architectural works, besides the numerous
State and foreign buildings, buildings for special
exhibits, public comfort and other purposes. The
buildings will all be abundantly filled with the most
curious and interesting exhibits, representing the

portant feature of the work is a spacious central
court, 134x176 feet, containing a large room, where
a fountain imparts an expression of life to the scene.
The mining and manufacturing interests of this west
half of America will doubtless be fittingly repre-
sented.
As Told in Colorado.
" I've got a sight for you that may interest you,"
said Lewis Emery, Jr. , to the guest who had pene-
trated to room 412 at the Brown Hotel this morn-
ing.
" This is my son, Earle C. Emery," he added, as he
unlocked one of the stout " grips " that stood on the
table. " We are just getting back to our home in
Bradford, Pa. ; we are in the oil business there, but
out in Calaveras county, Cal., we deal in this.".
As he spoke he undid one of a number of stiff buck-
skin sacks which he had taken from the valise and
poured out on a piece of paper about a pint of gold
nuggets ranging in size from the dimensions of a pea
to those of a butter bean.
" We've got lots of this coming," said Mr. Emery,
cheerfully, " but it will take some time and money to
get it out. Our diggings are away above the sea
level 2400 feet, in fact — and our sluicing watercomes
down to us from a height of 4000 feet, and it costs
money. That is due to the debris bill that was pa
through the influence of the fanners by the California
Legislature. But still it pays, and there's a world of
it to be done.
•• Why, the diggings of lS4i» and 1850 were as noth-
ing in comparison. The California placers have hardly
1 n touched, sir, hardly touched ; but capital is go-
ing in there, and they will be touched, good and hard,
too."— Denver, Colo., Post, July 10.
Wet Steam.*
William H. Edgar.
Wet steam is produced from two different causes
in the boiler, priming and foaming. Priming is due
to lack of delivery surface or lack of steam space and
to the mechanical construction of the steam dome,
especially the connections between the different
domes in water tube boilers. But wherever such a
mechanical defect might exist, the water you might
say would spatter the steam if boiler water contained
salts of soda.
Foaming is caused by saponification, due to the
soda contained in the water, and as a rule whoever is
using river water containing mud will have more or
less soda in the form not only of a carbonate but of a
sulphate. Well waters have tendency to foam after
running a week or two. I believe that in ninety
cases out of a hundred the moisture in steam is due
to saponification or to the presence of soda. There
might be a great excess of lime and magnesia in solu-
tion in feed water, but when the water is introduced
into the boiler and brought into contact with that
degree of heat, lime and magnesia is thrown out of
solution into suspension, and consequently get no
action whatever in the way of foaming. It does not
increase the density of the water. It is not a part
of the water. It is not in solution. Soda always re-
mains in solution. Ninety per cent of the waters
throughout the country used in the boilers contain
considerable lime and also some soda, and nine plants
out of ten are treated in one way or another with
some one or the other salts of soda, and get the same
action in all such cases received from the use of
artesian well water and surface well water in certain
places where the soil contains sulphate of soda and
generally the carbonates.
It is essential to get as dry steam as possible, and
one could get absolutely dry steam if he could use a
straight mineral cylinder oil without requiring the
admixture of any animal oil whatever. The animal
oil is necessary only to take care of the water. The
condensation washes off the mineral oil, necessitating
the compounding with an animal oil to hold it, to give
it the clinging, adhesive, film-cutting properties of a
good cylinder oil.
On the Burlington road they condemned the oil and
sent it back repeatedly month after month just dur-
ing the last couple of years — in fact the last year —
and could not buy anywhere else except of one com-
pany, and they had considerable difficulty in getting
an oil to meet their requirements. They finally
reached about 35% of tallow in the compounding.
They were using soda ash in the boilers, and the
more soda ash they used the more moisture they had
in their steam, the more they saponified the water
and the more moisture was carried over, and with
this moisture came soda, and the more soda that
came over the more it cut the animal oil, saponifying
it, forming soap, and they had considerable difficulty
before they found out really where the trouble lay.
I believe that throughout the country in different
plants a great many good cylinder oils have been re-.
peatedly condemned, and all due to the well water
used carrying the water a little too high in the boiler
or using some preparation of soda; and, of course,
the higher you carried the water, and the more you
agitated the water from a sudden opening, I suppose,
of the valve in the delivery of steam, the more read-
ily it would foam, and I believe that in all your prac-
tice in the engine room if you would watch your
water level and the nature of your water, so as to
know the amount of soda it might contain, it would
enable you to take better care of the oil question.
Caustic soda in a saturated solution would contain
59% of caustic soda ; a saturated solution of soda ash
would contain 40% soda ash, when it would begin to
cake ; with salt you would have a 35!% saturated so-
lution before it would cake. All sodium salts remain
in solution until the solution is saturated, and then
they cake and always cake at the hottest part of the
boilers. It is quite common in Kansas and down in
New Orleans and out in the Hawaiian Islands and
along the sea coast where they use salty water to
buckle the tubes and bag their sheets, due to salt. I
believe that nine-tenths of the wet steam and cases
of foaming are due to soda.

Cable Line to the Philippines.
Being in the Philippines to stay, and owning the
Hawaiian Islands, the United States naturally needs
telegraphic communication. Cable lines across the
Pacific are being discussed. Advocates of a govern-
ment line are figuring on two routes. The southern,
by way of Honolulu from San Francisco to Manila
while for shorter stretches india rubber suffices.
The question of Pacific cable communication will be
one of the foremost ones concerning the United
States in the first years of the twentieth century.

It is thought that the northern route by way of
Alaska to the Philippines, and in addition thereto a
separate line from California to Hawaii, could be laid
for about $12,000,000, as indicated in the following
table :
SINGLE. DUPLICATED.
Route. Miles. Cost. Miles. Cost.
International cable,
U. S. to Asia 4,883 $4,000,000 8,876 $6,000,000
Same, with cable to
Hawaii 7,283 6,500,000 12,276 9,200,000
American, northern,
to Philippines via
Alaska, with
branches to Japan
and separate cable
to Hawaii 9,335 9,000,000 12,735 12,000,000
American, southern,
via Hawaii and
Guam 7,750 13,500,000 14,250 25,000,000
This difference in cost is largely due to difference
in length of the links. The arguments against such
a route are to be found in the great natural difficul-
ties to be encountered — ice, fog and great depths,
but a cable on the northern route could be repaired
at any time of the year on any link, except during
temporary storms, and the cable ship could always
find a harbor within 100 miles of any break. By the
northern route the different stretches vary but
slightly in distance, and are all comparatively short,
none exceeding 850 miles, so that, in case of a break,
one cable ship, if it were found impossible to make
repairs, could easily relay one entire stretch, the
cost of which would not amount to more than
$600,000.
On the southern route, with its four great stretches
of 2286, 1254, 2593 and 1496 miles, the cost of a break
in great depth, in case repair were possible, would
probably amount to several hundred thousand dollars,
with the likelihood also of a necessity for the renewal
of an entire stretch, which would cost from $2,000,000
to $3,000,000.
Another consideration is the supply of gutta
percha, which has become so scarce and its price
consequently so high that its use in construction of
long distance cables has become very-costly. Gutta
percha costs $2 a pound ; rubber can be had at $1.30.
For long stretches of 2000 miles or more gutta
percha, however, is requisite as insulating material,
Evans Slime Table.
a device herewith illustrated and described, as fur-
nished by Fraser & Chalmers of Chicago. A is a
launder to conduct the slimes from the catch pit or
slime box to the distributor B, which has a partition
a, to separate the clear water from the puddled wa-
ter or slime water. The clear water is supplied by
pipe d, to the distributor, and runs over one-half of
the table D, while the slime water runs over the other
half, being controlled by the division piece L. The
sand and water being on one side of distributor B run
through its perforated bottom, and are distributed
equally over one-half of the stationary head C, and
run on the rotating table D into the circular launder
N, then through the waste pipes O O; the ores re-
main on the upper part of table D, and after concen-
tration are shielded from the action of clear water by
the cone-shaped head C. The proper grades of ores
are, through the action of clear water, washed about
half way down the rotating table P. They then come
in contact with the diagonal perforated pipe E, and
are rewashed by a succession of small jets from per-
forations of small pipe. The ore passing between the
jets is carried around on the rotating table D until it
comes in contact with a jet of water from pipe F and
conducting board G. The jet F conducts the ore into
hutch H, through pipe I. The middle or second
grade ore is washed off table D by the perforated
pipe E, and is deposited in hutch J, through pipe K,
to be rewashed. The head C is suspended from frame
M so that it can be readily adjusted relatively to the
table as may be required. The arms and segments
should be made of hard pine, about half seasoned.
The sheeting or surface should be of soft pine, and
must be green lumber and perfectly clear. The sur-
face of table must be true and uniform, the width of
the boards not to exceed 5 inches, tongued and
grooved. The speed of machine is one revolution in
eighty seconds ; pitch or incline of table, H inches to
1 foot ; pitch of head, If inches to 1 foot. The capac-
ity of the machine is stated to be twenty-five to
thirty tons per day of twenty-four hours.
The Congress of Mines and Metallurgy at Paris,
France, during the latter part of last month, was in-
adequately represented by American delegates,
though the prominence and utility of American meth-
ods were manifest in their mention by the several
speakers. "Employment of Electricity in Mines"
was the subject of an article by J. Libert, Director of
Mines at Namur, Belgium. Wolfgang Wedelin of
Berlin read a paper on "Electricity in the Mining
Industry." "Mechanical Extraction of Coal" was
described by various delegates, largely from Ameri-
can observation. Herrman Wedding of Berlin read a
paper on "Magnetic Separation of Iron Ores," de-
scribing the Edison and Wetherill processes. M.
Smits of Dusseldorf gave a further description of the
Wetherill process. N. Pallati of Sardinia read a pa-
per on the "Mechanical Preparation of Ores " in that
country. M. Syznan-Krowsky of St. Petersburg
submitted an article on "Russia's Mineral Re-
sources," and Jas. Douglas of New York presented
some statistical returns of the United States for
1899. There was some discussion as to the value of
mathematics to mining engineers, and a resolution to
hold the next meeting at Liege, Belgium, in 1903,
was unanimously carried.
Officers of the Colorado State Federation of Labor
are arranging to lease from the State a large amount

the upper part of this box is an overflow opening to
let off all the mud and worn-out sand which rise to
the surface. This overflow opening is connected to
the waste water drain or sewer of the mill.
The wheel is made spiral-like, consisting of a hol-
low passage or groove which starts from the outside,
where it forms a scoop, and is coiled round and round
until it reaches the center. The shaft of the wheel is
hollow and open on one side, which connects with the
spiral groove in the center of the wheel. The outer
end of the shaft is connected with a detachable hol-
low, tapering shaft, which works in a packing box,
preventing the sand from coming in contact with the
shaft. The vertical pipe is connected to packing
box by elbow. The pipe is 3 inches diameter for the
6-inch and 8-inch pumps and 33 inches for the 10-inch
pump. It connects at the top to a distributing box.
Valves are connected to this box to cut of the supply.
The pump wheel is made of steel plate, ^ inch thick,
and is made in three sizes, 6, 8 and 10 inches in width
and 44, 48 and 54 inches in diameter.
These spiral sand pumps are designed for pumping
sand, slimes, tailings and crushed ores. J. A. Fren-
ier & Son are represented by M. S. Hauser, 12 Front
street, San Francisco, Cal.
The new engines of the Denver & Rio Grande Rail-
way have iron pipes extending along the roof of the
cab, connecting with the boiler. Through this pipe,
without making a perceptible motion, either the en-
gineer or fireman can send, under 200 pounds pres-
sure, a jet of steam and boiling water that would
effectually kill or injure anything living that hap-
pened to be on the tender or the front end of the
baggage car. The blow-off cock thus arranged is
expected to prevent train robbers climbing over the
tender.

such extrusions. They were marked by an absence
of the violence which accompanied the earlier out-
bursts, due, perhaps, to a diminution in the quantity
of escaping steam and a lessening of the pressure
upon that which remained. The earlier ejectamenta
of a volcano are scoriaceous and vesicular; that is,
they have been penetrated and torn by the explosive
escape of superheated water vapor, while the lava
characterizing the later stages of activity is compact
and homogeneous. The creation of a vent serves as
a safety valve in releasing the tremendous pressure
of the steam, due to its sudden expansion when com-
ing into contact with incandescent fused rock. At-
tendant upon the relief given to that pressure, are all
the terrifying phenomena of the first outburst. Sub-
sequently the force of the eruption diminishes. The
lava ceases to be violently projected by escaping
high-pressure steam. The underground waters near
the conduit have become used up. The rise of the
lava underground, followed by its protrusion at the
surface, becomes a quiet process, which must be re-
ferred to a more deep-seated cause, namely, the local
which cools rapidly in the open air assumes the chara-
ter of a glassy substance, containing only a few
embryonic crystals, but that which cools slowly un-
derground, and while still subjected to great pres-
sure, is developed into completely crystalline rock.
Experiments with smelter slags, and a microscopic
examination of the resulting material, have confirmed
this proposition. In this way the lava streams which
have issued from. the vent are distinguishable from
the material which has solidified in the throat of the
volcano. The nepheline-syenite near the Lillie and
Vindicator mines is the granular equivalent of the
phonolite which occurs so plentifully all over the
district. The phonolite and the syenite have a similar
chemical composition, but their texture is very dif-
ferent. This is due to the fact that in the former a
crystalline structure has not been fully developed,
but the ground mass or matrix, as seen under the
microscope, being made up of crystallites — minute,
hair-like bodies without the properties, but with the
tendency to become, crystals. This indicates that
the rock cooled too rapidly to permit of proper
crystalline growth. The nepheline-syenite, on the
contrary, is made up entirely of developed minerals,
no part of the original ground mass having failed of
arrival at true crystalline maturity; so that even the
slight excess of quartz, though uncombined, presents
a crystalline structure. This indicates that the rock
cooled very slowly, giving ample time for the full
play of the forces which produce crystallization. It
is to be inferred that the nepheline-syenite fills an
old vent, or is close to it. The same inference is

readjustment of the earth's crust, causing the fused
rock to ooze out slowly. Many lava streams have a
glacier-like movement. They seldom progress more
than 3 miles per day, and often require a year to ad-
vance a few miles. Observers have described the
flows of lava which follow the first eruption as welling
out "with the tranquility of a water spring," as
"proceeding in silence, " as " being effected quietly
and without noise." All this is in vivid • contrast to
the paroxysmal outburst which marks the first stage
of volcanic activity. The difference is to be referred
to the relative quantity of steam taking part in the
process of eruption.
The period of quiet may have been, and probably
was, succeeded by a complete, though temporary,
cessation of activity. This interval may have per-
sisted for several hundred years. Geology is lavish
of time. The inaction was due to the diminution of
pressure consequent on the withdrawal of the lava in
the conduit of the volcano. Such a result would be
brought about by the shifting of the center of erup-
tion to another place along the line of fissure. The
first conduit of the Cripple Creek volcano became
plugged up by material which had failed of ejection.
Other minor vents may have been formed on the
flanks of the mountain which had been slowly formed
by the long continuance of discharges. When, after
an interval, a vigorously active condition was re-
sumed, the second eruption, in all probability, took
place through a new vent, produced, as the original
one had been, by a Assuring of the rock immediately
over congested masses of steam due to the water
which had accumulated during the interval of inac-
tion.
There is evidence indicating that the Cripple Creek
volcano had several vents. One existed near the
present site of the Hull City placer; another must
have been situated near Anaconda. The original
position of the orifice of an extinct volcano can be in-
ferred from the composition of the rocks. The lava

drawn from the patch of syenite-porphyry between
Gold hill and Squaw gulch. Further evidence sug-
gestive of the former existence of a vent thereabouts
is afforded by the steepness of the plane ofcontact
between the granite and breccia on the adjoining
Guyot hill. The dissection of extinct volcanoes in
other parts of the world, a dissection brought about
by natural erosion, which has cut valleys right into
the flanks of ancient eruptive centers, furnishes
numerous examples confirming such deductions as
have just been made with reference to the vents of
the Cripple Creek volcano.
The bulk of the material thrown up by the Cripple
Creek volcano was fragmentary, and became the
great mass of breccia now constituting the leading
geological feature of the district. The earliest lavas
extruded were of medium fusibility: namely, andesite,
and then phonolite. On reaching the surface, they
formed streams, the exterior of which became
promptly chilled to a black-looking slag, to which
escaping steam gave a cindery structure. The lava
rolled down the slope of the volcano with the utmost
slowness, making clinking sounds such as are heard
when the workmen empty the slag pots over the
dump of a smelter. Such lava streams weather
very easily; the exterior, by the contraction of the
surface due to cooling, becomes porous, and water
penetrates into the mass of them, disintegrating
them so that they are readily carried away by the
rains of spring.
The last extrusions of the Cripple Creek volcano
were of basalt. These were more limpid, and must
have formed streams which traveled much farther
than the less fusible phonolite and andesite. The
basalt, judging from the behavior of similiar lava
flows actually observed in the Hawaiian Islands and
elsewhere, would progress rapidly down the slopes
of the mountain and overwhelm the forests which,
i probably, clothed the lower portions of the Cripple
Creek volcano, setting them on fire and adding
greatly to the aspects of destruction presented by
the scene. Upon cooling, these basaltic flows would
be cleft asunder by symmetrical series of cracks
forming prismatic columns grouped like the pillars
of a Gothic cathedral. But where they were not
protected by a later covering of rock, the ruthless
hand of decay attacked them also, the frost of many
thousand years shivered the straight columns; and
the freshets of spring swept the remnants into the
torrents which fed the Arkansas river.
The successive periods of activity in the life of the
Cripple Creek volcano are marked by the sequence
of lavas extruded. This sequence is indicated by
structural relations, the older extrusions being
penetrated by the younger. But this is not all. The
crystalline structure and the chemical composition
of the rocks resulting from the cooling and consolidat-
ing of the successive lavas exhibit differences which
have been found to be closely analogous to those
presented by similar successions of rock at other
volcanic centers, both in the United States and in
Europe. The earliest lava extruded by the Cripple
Creek volcano was andesite. Then came the phonolite,
and, lastly, the basalt. These three rocks represent
types which vary in their chemical composition and
in their consequent fusibility. Basalt fuses at about
2250° P. ; certain varieties fuse at about 2000° P.
What is usually termed a "white heat " is equivalent
to a temperature of 2100° P. The least fusible rocks
are of the granite and trachyte class ; they fuse with
difficulty at about 2700° P. To the intermediate type
belong the andesites, which fuse at about 2500° P.
The relative fusibility of these rocks is dependent
upon the fusibility of their chief constituent, feldspar,
the variety in the basalts being labradorite, the most
fusible of the feldspars. Moreover, in basalt there is
present a good deal of augite, a still more fusible
mineral, and a large percentage of iron which, as in
smelter slags, contributes directly to fusibility. The
trachytes are largely made up of orthoclase, the
least fusible of the feldspars. The andesites are in-
termediate in composition and of medium fusibility,
their characteristic feldspar being oligoclase.
This fusibility used to be expressed in terms of
"acid" and "basic character," the rocks high in
silica and low in iron being at one extreme, those low
in silica and high in iron at the other. But Dana has
pointed out that this does not express it correctly,
fusibility being dependent not so much on the per-
centage of silica as upon the amount of alkali, namely,
potash and soda. Thus the rocks rich in alkaline feld-
spars are the most fusible. Free quartz exists in
most rocks; and the percentage of it, which is far
from uniform among the members of any particular
type, increases the acid character of the rock, so
that it becomes a secondary factor in determining
fusibility. Similarly iron occurs as an oxide (mag-
netite) in all rocks, to an insignificant degree in the
granites, but in the basalts and gabbros freely, so as
to form an important ingredient, giving them their
dark coloring. This large percentage of iron con-
tributes to easy fusibility; indeed, certain basalts
are known to become so limpid that they can be
taken up in a spoon attached to the end of a cane.
This question of fusibility would be of slight import-
ance were it not for one interesting fact, namely: it
has been observed in several volcanic regions that
lava of intermediate extreme types, namely, the very
alkaline or comparatively non-alkaline rocks, such as
basalt and rhyolite, respectively. This was the case
at the Cripple Creek volcano. It has been inferred
from these facts that in the earlier stages of volcanic
activity the lavas are mingled together underground,
and that during the period of eruption the heavier
portion separates from the lighter, causing two
diverse products to be separately emitted.

(Special Correspondence).— (Tho follow-
ing Is from an old and experienced Cali-
fornia miner) :
We arrived on the 18th. Have traveled
faithfully ovory day; have been up the
Snake, Cripple and tho Piney rivers and
many of their tributaries, also on Dexter,
Snow and many other creeks. I find very
little doing anywhero, excepting on the
I '• lai h, and most of the men for 20 miles
whom I have talked with declare thoy are
not earning over $3 per day. Thore are a
few exceptions, no doubt, doing well.
On Anvil creek thore are not over fifty
men working, owing to scarcity of water;
only about ton men working on Lane's
claims, below discovery; not a man work-
ing on Snow gulch, although there is rich
gravel on tho gulch. I panned out one
pan that yielded about SI. Lane's claim
at the head of Snow gulch will no doubt
turn out well when ho gets water, which
will have to be pumped.
All of these creeks are very flat. Usually
three men shovel into the si nice and two
men shovel out, and it has to be rich to
pay.
There are just two things possible to
savo tho reputation of this country: the
tundra, of which there is little or nothing
known, and the dredging of the boach
below high tide, which no one has yet
done. Yet thore are several who say they
are going to try it. There is any quan-
tity of machinery strewn along the beach
for miles. Much of it will never be used
nor oven taken away. I do not think any
man can judge fairly of this country in
twelve days, but I feel like advising my
friends to stay away for the present.
Things aro very much mixed — no law, no
socurity of titles. So far it is a town
boom, pure and simple.

G. H. Evans, M. E., well known in Cali-
fornia, has the management of a group of
properties owned by the Gold Pan, Fair-
view, Royal Blue and Oro Grande placer
mining companies, which aggregate
nearly 6000 acres of placer grounds in
the valley of the Blue river. During the
past few months these grounds have been
pretty thoroughly prospected With drills,
to ascertain the depth of material above
bedrock and its value. Some sixty holes
have been drilled at different points,
ranging in depth from 15 feet at the rim
to 70 feet in main channels. Six Evans
hydraulic elevators will be put in, which
are expected to handle 6000 yards per day.
Orders will soon he given for 1100 tons of

Blue and the other from French creek.
These grounds were worked in a small way
for years by their, former owners, by
whom the value of the material was
demonstrated. Under the present owner-
ship and management, two hydraulic
giants were set to work June 4, 1900, and
have been kept busy day and night since,
with the idea of getting in about five
months work this season. Manager Kings-
bury estimates that he handles from 700
to 800 yards per twenty-four hours with
each giant. In the sluiceway below one
giant there are 36 feet of triangular steel
riffles and J-mile of riffled sluiceway below
the other. Each giant works under a
pressure of about 175 feet head of water.
(See illustration, page 64.) Besides the
water which passes down the sluices from
the giants, there is a constant wash from
small reservoirs, which fill and empty au-
tomatically by means of gates and traps.
A special run of 600 yards of material
from these grounds last year gave a mint
return of $649.71. Near the bed of the
gulch a shaft was sunk to bedrock — 30
feet — within the past few days, the ma-
terial from which was found to be ex-
tremely rich. A bedrock drift will be run
several hundred feet from this shaft to de-
termine further as to values.

Lillooet, July 5.
Low grade siliceous ore containing only
a low percentage of sulphide is treated at
the B. C. bullion extracting works at
Silica. The mill was built to treat this
class of ore by the Pelatan-Clerici process,
on the Red Mountain railway, 3 miles
southwest of Rossland. The mill is prac-
tically in two sections, the upper or crush-
ing and sampling section, and the lower
or treatment section. The ore is delivered
in cars, are side-tracked, passing over a
track scale, where they are weighed, to
the receiving bins, which are under cover;
the cars, returning, are weighed again.
The electric current, as delivered, is 2080
volts to two motors, 50 H. P. An induc-
tion motor drives the crushing and sam-
pling machine in the upper section; a 75
K. W. synchronous motor furnishes power
for the lower or treatment section. The
mill is lighted throughout with electricity
by the use of two lighting transformers,
taking the current from the power mains.
All current consumed at the mill is paid
for on the meter basis.
The treatment the ore receives in the
first section is dry crushing. It is fed by
gravity to a crusher, thence by carrying
belt to a roll belted, thence carried by a
second carrying belt to another roll
geared, thence by a third carrying belt to
a bucket elevator and raised 40 feet for
sampling. The material leaving the last
set of rolls will all pass a J -inch mesh
screen, and a third of it a 30-raesh screen.
The elevator delivers the material direct
to a sampler, so set that one-sixteenth of
the whole is retained. This is further re-
duced by passing it through another sam-
pler, where one-sixth is cut out, giving a
sample of one-ninety-sixth of the whole;
this is the floor sample, quartered down
by a corno. The ore rejected by the sam-
plers falls from a hopper through three 6-
inch iron pipes to three storage bins.
The whole of the ore is easily converted
to either of the three bins. The ore from
the storage bins now enters what may be
considered the treatment section of the
mill, and is fed by two James automatic
feeders to two 6-foot Bradley crushers
driven from underneath, the crushing
taking place on a steel ring inside, diam-
eter 4 feet and 6 inches, outside 5 feet and
10 inches, with three rotary wheels, diam-
eter 4 feet 7 inches, face surface 8 feet,
weight 6475 pounds, making thirty revo-
lutions per minute; depth of discharge 5
inches, screen area 2730 square inches, the
tires being of prepared steel. The crushed
product discharged varies considerably,
depending on the character of the ore,
and on the ratio of water to ore during
crushing. When using a 60-mesh screen
and crushing a siliceous ore containing
from 4% to 6% of sulphide with such a
quantity of water that the resulting
sludge shall contain 50% of water, 90% of
the ore will pass a 150-mesh screen, the
remaining 10% a 100-mesh screen. But, on
the other hand, increasing the quantity
of water so that the sludge shall contain
four times of water, 17% passed the 150-
mesh screen, 12% the 100-mesh screen and
40% the 80-mesh screen, the remaining
31% remaining on the 80-mesh screen.
Generally, in stamp mill practice, all that
passes the 120-mesh screen is considered
slimes; this, however, is not the case with
ore crushed by this mill, as when a re-
source to wet separation is had, 40% of
the product passing the 100-mesh screen
is a good leachable product. The crushed

material from this crusher passes direct
to the four vats 9x15, where it was kept
agitated until the C. P. vats are ready to
receive a charge, which consisted of 21 tons
of dry material with 3} tons of water,
which gives fairly thin pulp. Theourrent
fur electrolysis used in the Pelatan-Clerioi
vats is a direct current generated by two
dynamos, each having a capacity of 12
volts by 750 amperes. Tho switchboard
Is so arranged that each one of the twelve
vats is on its own independent circuit, and
in such a manner that the current gener-
ated by cither of the dynamos can be con-
nected with any one of the twelve vats.
The relativo degree of the pulveriza-
tion the ore has been earned to varies
the chemical, electrical and their com-
bined effects, especially when dealing with
refractory ores. During tho whole time
of treatment agitation is kept up with tho
accompaniment of a"n electric current. To
the sludge salt is added, varying between
5% and 1% of tho weight of tho ore in the
sludge by degrees, the effect of the sodium
chloride boing first to increase the con-
ductivity of the solution. The effect that
takes place on the addition of sodium chlo-
ride to water brought between an anode
and a cathode is that the sodium chloride
in solution is disintegrated and reformed,
and thus it becomes the intermediary by
which, at the instant that chlorine gas
and sodium arc set freo, tho current is
able to communicate between the elec-
trodes.
During electrolysis, when the liquid
contains only sodium chloride, the primary
decomposition will bo sodium at the cath-
ode and chloride at the anode. To con-
sider the action of these products of elec-
trolysis as the sodium comes in contact
with the mercury, a small portion will be
dissolved by the mercury as amalgam, a
portion with the water, giving Na O H
and H. The chlorine liberated at the
anode, a small portion will attack the
metal of the anode, the greater part be
dissolved in the solution, some of which
will reform with the Na O H sodium chlo-
ride, another portion sodium hypochlorite
Na CI O and water. The action of the
chloride liberated and not engaged as
above will to some extent attack the free
gold and form Au CI.,, which is readily
deposited by electrolysis on the mercury.
The rest will attack the base metallic ore
present in a finely divided state, when
present, uniting with the metallic bases,
the sulphur and arsenic being oxidized by
the combined action of the chlorine and
sodium hypochlorite into sulphuric and
arsenic acids. These will again form with
the sodium, sulphate and arsenate, with
the consequent formation of free acids,
which must be neutralized with lime be-
fore potassium cyanide is added.
With the addition of potassium cyanide
it is advisable to have it in excess, not
only to allow for oxidation, if any hypo-
chlorite is present, but to allow the for-
mation of cyanogen at the anode, which,
being dissolved in the solution, will read-
ily unite with the minutest particles of
gold to form with the excess of potassium
cyanide the double cyanide of gold and
potassium. At the same time chlorine
and cyanogen, both yielded at the anode,
would form cyanogen chloride, which, in
the presence of potassium cyanide, is
effective in dissolving gold.
Owing to the high specific gravity of
the sludge, arising from the character of
the Rossland ore, the process finally
adopted was close classification of the ore
before treating with cyanide. For this
purpose Wilfley tables were placed before
the crushers. The sludge leaving these
tables contains an excess of water. This
is concentrated by the use of large vats of
conical form, fitted with a valve at the
apex of the cone. In these a concentra-
tion is effected, the ratio of water to ore
being as 1 is to 1.
The concentrated sludge flows direct to
the agitation vats, and on its way encoun-
ters a solution of KCN flowing in the oppo-
site direction, and in this manner the
sludge becomes well mixed with the KCN
solution, of such a strength that, diluted
with the water contained in the sludge, it
will give — depending on the ore — a solu-
tion in the aggregate of a value of .08%
to .15%.
After the charge has been agitated the
required number of hours fresh slaked
lime is added, the agitation being con-
tinued from five to ten minutes.
The exhausted sludge, together with
the gold solution, flows into concentrating
vats, and on its passage it is diluted to
such an extent that the sludge entering
the concentrating vats is of a consistence
of 3 to 1. The discharge valve at the
apex of these vats is kept shut until clear
solution commences to flow into the dis-
charge landers. The concentrated pulp is
now allowed to flow to a second similar
vat.
In this manner two-thirds of the gold
solution is separated from the exhausted
sludge by the first vat, and a further two-
thirds by the second, according to the
dilution that takes place between, re-
spectively, the agitation vat and the first
and second settling vats. Any desired
quantity of the gold in the more or less
diluted solution can be separated from the
pulp.
The gold-bearing solution now Hows to
tho Polatan-Clerici vats. Tho time to
effect this is dependent on current and
richness of solution. Six hours suffices to
reduco a $4 solution to 7 cents per ton,
with a current of 5 to 7 volts and 70 to 80
amperes.
The trcatmont of a siliceous ore assay-
ing from 4.3% to 7% copper, a trace of
lime and magnesia, 0.3 ounce gold, 0.5
ounce silver, gave a theoretical extraction
of 94% of gold and 73% of silver. A py-
ritic ore — gold 0.8 ounce, silver 1.3 ounces,
copper 1.8% and iron 22% — resulted in an
extraction of 89.87% gold and 72% silver.
At Grand Forks, on the 13th inst., ar-
rived the first ore-laden train from Phoenix
at the Granby smelter — ten carloads (300
tons) — from the Old Ironsides mine. It is
expected that as soon as the Canadian
Pacific Railroad supplies additional ore
cars the ore receipts at the smelter will
approximate 600 tons daily. The ore bins
of tho Old Ironsides, Knob Hill and Victor
contain 8000 tons, and there is an equal
amount in the stopes awaiting removal.
The Phoenix ores do not require any pre-
liminary roasting in heaps, saving from 25
to 50 cents per ton in handling charges.

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co.'s Scien-
tific Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Potato Cutter.— No. 653,385. July
10, 1900. J. E. Howell and W. A. Cham-
berlain, Montague, Cal. This invention is
designed for cutting and slicing potatoes
into forms for cooking, such forms being
known as "French fried" potatoes. It
consists of a table or support having sur-
faces at different elevations, one of such
surfaces provided with a longitudinally
extending slot, vertical and horizontal
knives are secured to the surfaces, and a
slide including end heads and connecting
sides for an open center adapted to receive
the potato to be cut. A bolt passes through
one of the heads and the slot and a cover
confined between the heads and sides is
hinged at one end to hold the article in
place. By pushing the holder back and
forward the potato is repeatedly brought
into contact with the cutting knives and
is thus sliced or cut into any desired form.
Acetylene Gas Generator.— No.
653,373. July 10, 1900. Chas. A. Bacon,
Lockford, Cal. ; assignor of one-half to Sam-
uel Cohn, Stockton, Cal. This invention
is designed for the economical production
of acetylene gas from carbide of calcium.
It comprises a generator with a succession
of independent carbide containing boxes,
a water tank with a rising and falling
gasometer and connections between this
and the generator whereby the gas is
transferred from the generator to the'
gasometer. Means are provided for auto-
matically cutting off the flow when the
gasometer is full, and a means for auto-
matically supplying water to the gen-
erator. A controlling cock is actuated by
the rising gasometer so that the supply of
water is cut off when the gasometer is
sufficiently full of gas. There is a trap in-
termediate between the water supply and
the generator, and a supplemental passage
connecting said trap with the gasometer
so that any gas produced after closing the
valves will be admitted into the gasom-
eter and the pressure upon the generator
relieved.

(standard ounce, 925 fine); New York, bar
silver, 61Je (1000 fine); San Francisco,
61Jc; Mexican dollars, 48£c.
The troubles in China are expected to
occasion an advance in prices. The

States, but the price is fixed in London.
The United Metals Selling Co. controls
the sale of silver for export and domestic
use.
The price of silver in India is reported
71J to 72}. The small boom has been in-
duced by a real demand combined with a
temporary short supply, a great deal of
the current business being purely specu-
lative. All Mexican securities have ad-
vanced in sympathy with silver.

"",1899. /
Nicaragua, June 20,
Alter an experience covering a period of three years with both the first and improved " Tremain Steam Stamp Mill," in every par-
ticular I have found it perfection— a money maker, and just the thing for a small capital, while companies organized on a large scale
would do well to look into its merits.
I find no difficulty in crushing eight tons of ore per day and running on hard ore. This mill should be a winner.
Very truly yours,

GATES IRON WORKS, CHICAGO.-GENTLEMEN :
Our Tremain Mill is giving us good results, and although being in operation since 1892 has not cost us $1 for repairs, and to-day is
making 180 drops per minute with 95 lbs. steam pressure.
The ore we are working at presentis^oft and -we mill in. 24 hours, using No. 10 slot screen, 15 tons.
Yours truly,

Running Under Compressed Air in West Australia.
293 ST. GEORGE'S TERRACE, PERTH, W. A., February 6, 1900.
F. R. PERROT, ESQ , Agent op Gates Iron Works, Perth, West Australia.
Dear Sir: In reply to your enquiry as to the working of the Tremain Mill on the Burbanks Grand Junction, I would state
that at the start we worked this from the boiler supplied by the Gates Iron Works Company, but owing to certain irregularities of
the running, which were in a measure due to the intermittent supply of ore and the short time that we were able to run it per
day, I finally laid on air piping from my air compressor, a quarter of a mile distant, and used the boiler as an air receiver,
with the result that I got an absolutely constant run, which, I believe, averaged about 105 drops per minute, and this was kept up
with great regularity and showed a much better return in the treatment of the ore. The usual air pressure in this case was 8J lbs ,
whereas under steam we were not so satisfied with the result as worked at 100 lbs. By this we were also saved in cost the charges of
stoker, fuel and water, and it was worked with much greater cleanliness, and during the whole time the mill was running— which was
several months — it never froze up on us or showed any signs of trouble in that direction.
The mill is now temporarily stopped, but when it is again started I shall most decidedly continue the use of compressed air.
Yours faithfully,
[SiGNEDl GEO. HEWER.

THE GRI
THREE ROLLER
ORE 7VYI
The Griffin Threo Roller Ore Mill is a sinip.y constructed Mill, suitable for working all kinds of ores that
require uniformly fine crushing by the wet process. This Mill is a modification of the well-known Chilian
Mill, but the rollers run upon a crushing ring or die, which is inclined inwardly at an angle of about 30 degrees,
the rollers themselves also boing inclined to the central shaft of the Mill, thus utilizing the centrifugal force,
as well as the weight of the rollers themselves as a crushing agent. Tho Griffin Three Roller Ore Mill is there-
fore a Mill of great strength, and has few wearing parts. Wo construct theso Mills with extreme care, using
only the best of raw materials, which are most carefully worked by men who are specialists as mill builders.
We sell the Griffin Ore Mill on its determined merits, and will gladly supply full information regarding it to
any one. ■

" Empire, Colo. : The success achieved by the Cammett

Some Practical Reasons Why the WUflcy Concentrator Should Be Used (n
Gold Mills:
It will successfully handle three or four times more material
than any belt Concentrator made, without exception.
It will save more sulphurets in proportion while so doing', and
catch any float gold, amalgam or quicksilver which may escape
from mortars or plates.
It will make cleaner and much more valuable concentrates, thus
saving useless expense for transporting valueless material, as
also extra cost for treatment.
It requires little or no attention when once adjusted and no ex-
pert Is required to either-adjuBt or run the machine.
It will save much expense in power and room, and the first coat
of a mill requiring concentrators.
It has no expensive belts to crack and wear out, nor complicated
machinery to keep In repair.
It 1b the only sensible plan of concentration, as any kind of mate-
rial can be worked, which is not true of any style of belt ma-
chine.

take the place of two or
three belt concentrators of
any style and do very nmch
better work. Easy adjust-
The above illustrates the "Union'' 25 H. P. double cylinder divided drum mining hoist for double com-
partment shaft. Cages and cars balance each other, therefore power is only used to raiBe ore; cost of
hoisting ore Is therefore reduced to the minimum. Made in sections for mountain transportation.

Mining Experts.
In all sciences expert evidence is BOUgbl whore
there is dispute or lit-
igation. In mining
cases the costs of ex-
pert evidence are fre-
quently one of the larg-
est items in the bill of
expenses, sometimes ag-
gregating $2i>0,000 in a
single case. The com-
petent expert is a neces-
sary factor in a mining
case, where the interests
involved or the intricacy
of the question makes
justice more likely to be
secured by the assist-
ance of men who can
state or explain facts,
and thus aid the lawyers
and the judge to prop-
erly deduce correct
statements and decision.
There is considerable
harsh criticism of min-
ing experts, partly be-
cause of the conflicting
opinions sometimes giv-
en, and some of it is deserved. But even judges'
decisions are occasionally reversed, and the Su-
preme Court of the United States has reversed
itself. No one is infallible. The chief trouble lies in
some judges being at the mercy of unscrupulous "ex-
perts " who impose on their ignorance of the facts.
The real mining expert is of value to his client and
the court because of his honesty, truth
and self-respect, and because he is
fully equipped for the case, being qual-

ifled to give testimony. The wealthier of two lit-
igants is not always right, nor is the more fa-
mous expert. The real expert will state the truth as
it appears to him, will not endeavor to confuse nor
confound the facts, and will not allow his answers to
be influenced by any other consideration than his own
independent judgment. In so far as any mining ex-
pert giving testimony in a court of judgment deviates
from or falls below this standard, so far does he fail
in just claim to being a " mining expert." It may be
that in time the court will have an expert of its own
as a technical adviser incases where there is a "con-
flict of evidence." The present tendency is that
way, as a matter of necessary evolution.

Viewed in the degree and kind of information in
dividually possessed there are three kinds of miners:
men who have studied in a mining school and nothing
more; men who never saw the inside of a mining
school but have grown up and been engaged in the
actual work of mining for many years; and men who
have learned a good deal in a good mining school and
have had subsequent practical experience in actual
mining work. Each has his place, and, in a way, each
one can do good work, but it will probably be agreed
with by a majority of miners that the third named —
the man who unites the knowledge gained from the
experience of others given in books with that from his
own experience gathered in actual work — is, probably,
of the most benefit to himself and those with whom
he is associated. In these sunset months of the
century it is in order to discuss this subject, a very
important one, on which a great deal has already
been well said.
The young mining engineer, " fresh " from school,
is credited with knowing a good deal, with ability to
obtain the best results with the least expenditure of
money, time and labor under given conditions, and is
supposed to have knowledge of how work should be
done to insure such results. A young man of intelli-
gence and trained in competent schools would doubt-
less be able to do good work under some conditions.
But, of many varieties of him, the man whose knowl-
edge is confined to what he has learned by the hard
knocks of experience; the man who has learned about
the work by actually doing it, is ofttimes the far
more usef nl member. The man who got his mining
education about the same way as a chicken gets its
breakfast — a grain here and a grain there — and who
has been doing practical mining all his life, has in
many ways a superiority, the chief trouble with him
being that occasionally he thinks he knows it all,
though this phase of self-sufficiency is sometimes ob-
served in the mining school graduate.
Success in this class of work offers many shining
prizes. Indeed, the close of this century finds the
science of mining offering as much inducement as any
other occupation, as it is becoming a matter of large
undertakings, where much is involved, and, where, as
in nearly everything else, mind rules matter: the
manual labor being relegated more and more to ma-
chines, and the man in charge expected to be suffi-
ciently up in the theory and practice to make him a
man of affairs, capable of successfully handling large
schemes. This man will probably be oftenest found
among those who are well grounded in mining educa-
tion and who have had the experience that can only
be acquired by actual work; that is, the man who
combines practice with what is commonly called
theory will be the best man. Knowledge gained in
the mining school is developed into its fullest value by
practical work, though without such primary educa-
tion he is likely to lose considerable valuable time.
His experience will forbid that he err in attempting
that which is only apparently possible; it should
forbid that he undertake to put into force rules of
text books without the modification which almost
every practical piece of work enforces upon them;
it will also give him the ability to seize the oppor-
tunities often presented in practical work and to
make the best of the situation. It is to this combina-
tion; to the existence of men who have combined the
faculties attained by years of hard labor in the doing
of work as well as the knowledge of text books, that
much of the great progress in scientific mining is
due.
The time is about past when the miner who "does
not go much on science " has the floor. Time was
when the scientist or the geologist was a sort of good
joke, to be gently joshed by the men who were doing
the work and who in a kindly superior manner de-
clined to take him seriously. This was the time when
a choice kind of a joke in a mining camp was to put
up a job on anyone who laid claim to any kind of
scientific mining — sometimes' with entire success, as
some of the book miners were as sadly deficient in
practical knowledge as any men over-educated on a
subject of which they had no practical information.
These were the days when the orthodox miner put all
the mining schools under excommunication and al-
most universal]}' voted that if he did not know it all,
he came pretty near it, and that the man from' the
mining school came just as near not knowing anything
about it. That day has passed and intelligent miners
everywhere now recognize the value of properly
directed scientific mining.
The value of a man who is able in an emergency to
discern and remedy faults; who can tell when ma-
chinery is doing its full duty; who can effect the
greatest saving of values from the ores treated; who
can determine the most economical method of work
but who can refrain from making such economy too
expensive; who understands the effect and use of ex-
plosives; who has up-to-date knowledge of rock
formations; who understands timbering, ventilation
and drainage ; who knows ho w to keep from gouging the
eyes out of a mine; who is able to block out sufficient
ore to insure continuous operation; and who does not
hold himself so far above those with whom he daily
associates that he would fail to recognize the " man,"
no matter in what capacity he may be employed —
such a man is not an ideal by any means; there are
many of him, but they did not get all their education
in a mining school, nor did they content themselves
with scoffing at those who have.
There has been a tremendous amount of money and
effort misspent in mining. Every miner who reads
this can call to mind right in his own locality where
a little intelligence, where some knowledge of geology
and the science of mining would have made all the
difference between the place having a black eye and
being a producing camp. Monuments to unwise mine
management are within sight of each other all over
this west half of America. Idle mills built to operate
visionary processes; tunnels running away from the
vein instead of toward it; costly shafts sunk just
where they should not have been; an ideal plant built
to crush and treat the ore before its sufficient exist-
ence was proven: all these things go to demonstrate
the difference in the man. For, after all, as in nearly
everything else, the question comes down to what
kind of a man is at the head of the project. If he
has knowledge, judgment and skill he can make
money develop a profitable payer. If he knows noth-
ing except from books, or if he has a scorn of any-
thing in books his self-sufficiency may waste invest-
ors' money and throw himself into the ranks of the un-
successful.
Some splendid specimens of printing are regularly
received in the shape of catalogues sent by enterpris-
ing makers of and dealers in all kinds of machinery.
Many of them are valuable trade treatises, full of fine
description of appliances and devices for economical
mine work, and are handsomely illustrated. Some of
these are rolled and otherwise poorly mailed, which,
to the writer, seems a mistake. It is not economy to
spend thousands of dollars in preparing a really val-
uable work and take away from its value to the maker
by " saving" a few cents in its proper transmission.
A catalogue should not ' be rolled. It is, meant to
reach a prospective customer, and should get into his
hands in such a shape as to have lost none of its at-
tractiveness. It is good business to put out a good
catalogue, but it is poor economy to roll it tight and
put on a flimsy wrapper in sending it out. Next to
a good advertisement, in the paper seen by the men
most likely to be buyers of what is advertised, a good
catalogue is a trade getter, but it should be put out
in good shape.
Commendable Work.
The receipt of a monograph, " Geology of the Lit-
tle Belt Mountains, Montana," an extract from the
twentieth annual report of the U. S. Geological Sur-
vey, is a good example of the fine work that branch
of the public service is doing. The U. S. Geological
Survey is of great and constant aid to the mining in-
dustry, and of late years is paying back in some de-
gree the debt that geologists owe to the miner, for
to mining more than to anything else is geology in-
debted for its present advanced position. Thus the
matter is one of reciprocity, and in this regard is to
be noted and commended the policy of Director Wal-
cott in his zealous and successful effort to give timely
and accurate knowledge of requisite facts. Recog-
nizing the requirements of practical, up-to-date in-
formation, has been adopted the policy of making al-
most immediate reports of great value to miners con-
cerning newly discovered districts. To the Montana
monograph is appended a list of sixty-two geologic
folios now ready for public distribution, to be fur-
nished to any applicant on payment of a small fee.
When all these folios are furnished they will consti-
tute a geologic atlas of the whole nation.
This work goes steadily on year by year, and the
sums appropriated are wisely expended. Not the
least of the good resultant or made possible is the
kindly co-operation of the Federal survey with the
several State surveys, and continued co-operation
wherever practicable. The U. S. Geological Survey,
as at present conducted, recognizes that were it not
for the mining industry there would be little practi-
cal need for its existence, and the broad policy of its
officers and attaches is commensurate with the area
and industry they attempt to cover.
In this regard it is to be regretted that the several
States are so backward in taking advantage of their
possibilities in State geologic survey work. The U. S.
Geological Survey is empowered to undertake topo-
graphic mapping in any State where it is asked for
by the State, the expense to be divided equally be-
tween the State and Federal government. The func-
tions of the U. S. Geological Survey and those of any
State geological survey are different, and are so rec-
ognized, but, while each has its sphere of action, co-
operation can be secured entailing increased benefit
to the very ones all this is intended to benefit — the
miner and, indirectly, the mining industry.
The origin of ore deposits is an interesting and
practical subject of discussion, and one that has had
considerable of value contributed by men who have
given the vast subject careful study. The subject is
one of scientific inquiry and of immediate practical
value to metal miners everywhere. It is, of course,
easy to say: "We don't care how the ore originated.
The question for us is where is it and how can it be
best reached and most economically treated ? " Yet
a satisfactory solution of the more abstract scientific
inquiry will aid in answering the concrete practical
requirements of the miner. This last fact gives great
importance to the contributions of geologists and
scientists during the past twenty years, the result
being that the matter is emerging from the shadowy
domain of theory and hypothesis, and is assuming the
nature of an exact problem which admits of definite
and satisfactory solution. In the last few months
have been received several excellent monographs on
the subject of the genesis of ore deposits, and another
is promised. The requirements are recognized as
embracing a scheme acceptable to geologists and of
practical aid to the miner, and it is along these lines
that present advance is being made.

Hydrogen and oxygen can be produced from water
by an electric current, but a cheaper and easier way to
produce hydrogen is by the action of hydrochloric or sul-
phuric acid on zinc; and to "make" oxygen, by heating
manganese dioxide and potassium chlorate in a retort.
There is no fixed date for the annual convention of

Were all the gold mines in the world productive,
solely, of free-milling ore, there would, doubtless, be
great scope for bromine processes, but the usual presence
of other metals for which bromine has a great affinity
precludes extensive belief in the universal value of its
operation.
A bullet fired at 45° elevation is supposed to travel
through the most space — that is, of three of the same
weight, fired with the same force and under similar cir-
cumstances, one horizontally or any angle but 45°, one
perpendicularly and one at 45°, the latter would have the
longest trajectory.
Green wood when cut down contains about 45% of
its weight in moisture; kept for several years in a dry
place it will retain 15%: if thoroughly dried, it will, if
exposed to air under ordinary circumstances, absorb 5%
of its weight in water the first three days and continue
absorption till it reaches about 15%.
Doubtless there will be further development in
stamp batteries, probably in the direction of increased
adaptation to dry crushing, 'and the introduction of vari-
able adjustment as will enable any number of stamps in
the same battery to crush any kind of ore, the latter
presenting the most difficult problem.
THERE is no law nor statutory provision in California
or in any other State against hydraulic mining. In Cali-
fornia a decree of a court and injunctions under that de-
cree have interfered with hydraulic mining operations,
but Congress some years ago passed a law under which
hydraulic mining may be carried on. That law, known
as the Camiuctli Act, has been declared to be constitu-
tional, in a case where its constitutionality was attacked
by a California hydraulic mining company at North
Bloomticld. Cal.
Permanganate of potash is an antidote for the
bite of a rattlesnake or other venomous reptile. To use
it the wound should first be enlarged and then saturated
with the drug, after having first tied a shoostring, sus-
pender or some handy ligature around the limb, as the
leg or arm is usually the point attacked.
The term "lode" is more general and all-embracing
than "vein." There may bo several "veins" in a
■lode.'' The latter term includes everything botwoen
tho hanging and tho foot wall, and if beyond those there
be an impregnation of country rock of equal valuo to
that in tho fissure, that, also, would be considered as
part of tho "lode."
There are abundance of quartz and placer gold min-
ing properties in tho island of Borneo, but no one should
think of going there unless with abundant capital, cre-
dentials and intimate acquaintance with all the condi-

day, En.g!ish money.
If exhaust steam be used direct for heating water
passed over amalgamator plates, it is liable to contain
sufficient oil in solution to form a coating on the surface
of the quicksilver and thus prevent complete amalgama-
tion. Where exhaust steam is thus utilized, none of it
or of tho condensed water should be allowed to come in
contact with the plates.
THE swindler and bogus mine promoter prefers the
newest mining fields as affording less likelihood of imme-
diate discovery of fraud, it being sometimes difficult to
get reliable information about a property in a now dis-
trict. Somo of the prospectuses are wonderful illustra-
tions of the possibilities of language when used by
men in ignorance or defiance of the facts.
In measuring a miner's inch of water, the surface of
the water is to be exactly 6 inches above the center of
the discharge. If the aperture be 2 inches in height,
each sq. in. of the opening in the plank (1| inches thick)
will discharge a " miner's inch " = .02499 cu. ft. per sec-
ond, 1.4994 cu. ft. per minute, 89.964 cu. ft. per hour,
2159.146 cu. ft. per day of twenty-four hours.
The Union Iron Works of San Francisco, Cal., has a
device intended to increase the capacity of the stamp
mill, being the placing of a small fine crusher between
the ore feeder and the mortar. The feeder is located
above the battery floor, is operated from the stamp, and
automatically feeds the ore into the crusher, which, in
turn, delivers it in j-inch cubes to the stamp.
That a steam boiler explodes because of gases gener-
ated in the boiler is only an unproven hypothesis. A
boiler explosion is because some part of it is too weak for
the pressure. The weakness may be due to poor work-
manship, design, material or defect. Nor is there any
"accident " about such explosion. It is the result of the
action of exact law, and is no more " accidental " than
the phases of the moon.
In the case of Hartman vs. Smith, 7 Montana, 19, the
court held that "all that is necessary to make the claim
of a mill site by the owner of a non-contiguous mining
claim valid is the reasonable use and occupation thereof
for mining purposes in connection with a mining claim."
A mill site may be patented by compliance with the same
requirements regarding survey and notice as are ap-
plicable to veins or lodes.
The Copper King property is 27 miles from Fresno,
Cal. Four reports were made by mining engineers upon
it in 1898. The last of the four was made by F. O. Harvey,
Dec. 2, 1898, who estimated that there were "60,000 tons
ore in sight of 91% copper ore, wet assay 4 dwts. gold,
4 ounces silver ; ore at surface, 7000 tons 9J% copper, 4
dwts. gold, 31 ounces silver; 3600 tons 3J% copper, 3
dwts. gold, 3 ounces silver."
The Mauser rifle is not considered equal to the Krag-
Jorgensen. The main difference between the two is that
while both are bolt guns, the Krag has a magazine
which, filled with five cartridges, can be cut off so as to
make the rifle practically a single shooter ; the Mauser's
magazine can not be so cut off. Then, in the Krag, the
bolt is opened and closed by the action of cams ; in the
Mauser the user has to compress the main spring by di-
rect force.
In Tarapaca and Atacama, Chile, S. A., nitrate of soda
is found in horizontal or slightly inclined beds or strata
6 feet from the surface, mixed with sand and pebbles.
This substance, locally called " caliche, " is blasted out
and hauled to a maquina, where it is lixiviated and
rudely refined, the tailings, or ripios, often containing
from 5% to 15% nitrate of soda. Tho deposit is from 1
to 2 feet in thickness and is indurated something like the
cement gravel of the California drift mines.
The temperature of steam in contact with water de-
pends upon the pressure under which it is generated. At
the ordinary atmospheric pressure (14.7 lbs. per sq. in.)
its temperature is 212° F. As the pressure is increased,
as by tho steam being generated in a closed vessel, its
temperature and that of the water in its presence in-
creases. Saturated steam is steam of the temperature
due to its pressure — not superheated. Superheated
steam is steam heated to a temperature above that due
to its pressure. Dry steam is steam which contains no
moisture. It may be either saturated or superheated.
Wei steam is steam containing intermingled moisture,
mist or spray. It has tho same temperature as dry satu-
rated steam of the same pressure.
South AFRICAN Rand mine managers figure that
the] can resume their former output within six mouths
after cessation of hostilities. There are a good many
things in the way. Were peace proclaimed to-morrow,
the force of native workers is so Boattered and demoral-
ized that tho question depends as much upon the possi-
bilities of obtaining native manual labor as upon replac-
ing tho machinery of the mines. They also figure that
there may be an opportunity to reduce the salaries of the
natives and thus ronder practicable the working of minos
which produce in small quality.
Under Colorado State law a company when incor-
porating must pay to the Secretary of State $10 for the
first $50,000 of capitalization, or fraction thereof, and 15
cents for each additional $1000 capital stock. A $2,000,000
capitalization would havo to pay the Secretary of State
$302.50. The present war tax requires 5 cents on each
$100 face value of each original issue of certificates of
stock in any company or corporation. On tho capital
stock named this would mean $1000 more, federal revenue
tax. The county clerk would charge about $2.50 for fil-
ing the articles of incorporation.
THE profession of mining engineer is a good one for a
competent young man to embrace, and, properly
equipped mentally and physically, ho should bo of value
to himself and others therein. A certain amount of
bodily strength and activity is necessary. No business
makes greater demands on the constitution, and without
a vigorous physique the utmost meed of success could not
be attained. The editorial on the opposite page contains
additional suggestions on this topic. Thero are many
excellent mining schools in this country in which a
thorough training for actual work can be had at com-
paratively small cost.
There are several processes of eloctrolytic extraction
of zinc from its ores, all resombling each other to
some extent, the ore being crushed, roasted and leached
with suitable solutions of acid or salt, by means of which
the zinc is dissolved out. A current of electricity is then
passed through the solution, when the zinc is deposited
at the cathode, and the exhausted effluent is returned to
the leaching vats to be renewed by passing through a
fresh charge of the prepared ore. In the Siemens &
Halske process zinc sulphide is employed to liberate the
zinc; in the Dieffenbaeh process zinc is produced by elec-
trolysis of a zinc chloride solution.
The old laws on the flow of water have been entirely
discarded and the literature on that subject as applied to
mining has been entirely rewritten. Books and articles
in technical papers of a few years ago are back numbers,
and are as out of present use as the almanacs of the
years in which they were written. The same remark ap-
plies in a modified degree to pumping machinery and the
application of electricity to mining. The science of min-
ing is progressive, and the rate has been a rapid one in
the past ten years. The best way to keep up is *o weekly
get some technical mining paper in touch with the times
and with the mining men now on earth.
To prepare a blasting charge, cut a piece of safety
fuse to the right length and carefully insert the fresh-
cut end in a blasting cap. See that the cap is free from
any particle of sawdust before inserting the fuse. Press
the fuse gently into the cap as far as it will go. Crimp
the open end of the cap tightly around the fuse with a
pair of cap nippers, but under no condition disturb the
fulminate or filling in the cap. Then open one end of
the cartridge carefully, and with a sharpened lead pencil
or pointed wooden stick make a hole in the powder, in-
sert the cap end of the fuse, being careful to see that at
least J inch of the cap remains out of the powder. Then
draw the paper closely about the fuse and tie it with a
strong cord. Another way to prepare or charge a hole
is mostly used in dry mines, uppers, etc. For instance,
if three sticks of powder are used for a blast, place two
and one-half sticks in a hole, then put in fuse with cap on
end, let down to powder, keep fuse on side of hole, then
slit the paper on powder three or four times lengthwise
and drop in hole, ram or tamp carefully at start, then
tamp as usual. Never allow smoking or fire of any
description near the powder nor leave any loose caps or
fuse in the vicinity of the powder.
The pressure of the atmosphere is about 14.7 lbs. per
sq. in.; with a perfect vacuum it would sustain a column
33.9 feet high. The height that a pump will lift water
depends on atmospheric pressure, which decreases as al-
titude increases: about | lb. per sq. in. for every 1000 feet
ascent. Thus the altitude being 4500 feet the pressure of
the atmosphere is 2} lbs. less than at sea level, or, ap-
proximately, 12J lbs. per sq. in. The moisture in the air
makes a difference in the pressure. The readings of. a
barometer indicate both of these. A barometer reading
28 inches would indicate a pressure per sq. in. of 13.74;
281, 13.86; 284, 13.98; 28|, 14.11; 29, 14.23; 29], 14.35; 29J,
14.47; 29J, 14.60; 30, 14.72; 30J, 14.84; 30}, 14.96; 30|, 15.09;
31, 15.21. One pound per sq. in. corresponds to a head of
2.30947 feet of water; so, to find the lift of a pump, multi-
ply the pressure per sq. in. by 2.30947. If the barometer
stands at 28, the corresponding pressure = 13.74 lbs. per
sq. in.: 13.74 X 2.30947 = 31.73 feet = "lift" of water.
Of course, the pump would not lift this height, as it can
not produce a perfect vacuum, and even if it could, there
must be enough difference between the pressure in the
pump chamber and the atmosphere, not only to sustain
the height of the column, but to overcome its friction.

Silver Smelting in Mexico
NUMBER I.
Before the London Institution of Mining and Metal-
lurgy was recently read a paper by Otto H. Hahn,
"On the Development of Silver Smelting in Mexico,"
which, among other things, goes into minute detail
and criticism of the method in operation at the time
the article was prepared, at Smelter No. 3 of M.
Guggenheim's Sons at Monterey, Mexico.
Much of it is of general interest, and a free con-
densation of the paper so far as it applies to that
particular smelter is herewith published. After
some preliminary history and description of the
power plant, Mr. Hahn passes to the sampling de-
partment. He says (much condensed) :
The sample mill is a most important part of a cus-
tom smelter, for, on the assay results of the samples
taken from the ores, the settlements are made. A
mistake in sampling may entail serious monetary
losses upon the smelter by basing the purchase of an
ore on false values and the slag calculations on wrong
analysis of the earthy ingredients. It is therefore
conventional between smeller and ore vendor for the
latter to have a representative on the ground to
watch all the operations an ore has to go through
from the time of its arrival at the weigh bridge till
the final sample is turned out. Since all ore is re-
ceived in railway cars, the smelter is advised of its
shipment by having bill of lading mailed to him; and,
being in most instances conversant with its char-
acter, the official in charge of the sample mill will
know how to dispose of it according to instructions
he has received from his superiors. After the ore is
weighed, the first thing to do is to take moisture
samples. The man entrusted with this work has a
number of pans ready with tags in them, specifying
mark of ore, number of car and day of arrival. He
is also provided with a trowel to dig up the ore and
a hammer to break up lumps, for it is necessary to
get a fair proportion of both fine and coarse ore.
The moisture samples are immediately taken to the
office at the sample mill, where an even number of
grams — say 500 — is weighed up on a small platform
scale made for this purpose. The samples are then
put on the drier — a coil of iron pipe of sufficient
length — through which steam is allowed to circulate.
The next day these samples are reweighed, and the
result is recorded in the moisture book. Ores are
divided into parcels or lots of a certain number of
tons, according to agreement between purchaser and
vendor. Low-grade ores of a uniform character are
usually divided into 100-ton lots or more. When a
lot is closed, the net weight of each carload is multi-
plied by the moisture factor, and then the average
moisture of the whole lot is computed.
Since a considerable proportion of the ores re-
ceived arrives in sacks, these are cut open in the car
and emptied right there; or, if the ore is rich, they
are taken to the sample mill, reweighed on a mov-
able platform scale and emptied on the floor. The
moisture sample is then taken as usual. It is a
matter of course that the sacks have to be turned
inside out and shaken to free them from ore dust be-
fore they are weighed and returned to their owners.
The iron ores and other ores of little silver value
are unloaded in the open air, while lead ores and
high-grade silver ores are put into the covered ore
shed between the sample mill and the blast-furnace
shed. The roasting ores are unloaded into bins near
the calciners, if they are fine, or on a platform ad-
joining the sample mill if they need crushing.
Ores of the same class are "bedded," that is,
spread out in horizontal layers of the same thick-
ness, one above the other. If another lot follows, the
previous one has to be leveled off before putting the
new one on the bed. The size of the beds is limited
by the space available, the height and the time when
they are wanted. So of iron ores, beds of 2000 tons
are made up, of lead ores from 800 to 1000 tons, and
of silver ores less. Of course, these beds are num-
bered, and a strict record must be kept of the lots
composing them and of their weights. If the samples
of any of these lots are put on another bed, their
weights must be deducted from the weights of the lot.
The numbers of the beds must be set up on top of
them and marked on material indestructible by the
weather. Big lumps are broken with a hammer and
the fragments are distribted evenly over the surface
of the bed.
During the unloading process samples are taken by
throwing the twentieth, tenth, fifth or third shovel —
according to richness of ore — into a wheelbarrow,
which, when full, is wheeled to a platform adjoining
the sample mill and piled up there. The sample is
marked by sticking a peg, with a card attached to it
containing the description of the ore, into the top of
the pile. Samples of concentrates of rich ores are
preserved in numbered bins erected opposite the
sample mill, and their tags are nailed .on the door-
posts of the bins. Samples from wheelbarrows which
have been upset must not go to the sample pile, but
must be rejected. After a car is unloaded its floor
must be kept clean, and also the track, and the
sweepings are thrown on the bed.
If a lot of ore is closed which is marked on the bill
of lading or ordered by the consignor, the sample is
made by spreading it out in a flat, circular pile,
breaking up the lumps with a hammer and quarter-
ing it down to convenient size. If the ore is hard and
tough, the whole sample must be passed through a
crusher previous to quartering it down. The reduced
sample is then taken to a pair of rolls in the sample
mill, and, after crushing it to pea size, quartered
down again to about five pounds. This further re-
duced sample is dried at a temperature of 212° F. on
the dryer and then put through the sample grinder.
The material from the sample grinder is passed
through a 120-mesh brass wire screen, and the re-
mainder is ground by hand on a bucking-board till it
is fine enough to pass also through the same sieve.
The powder or " pulp " so obtained is now thoroughly
mixed on a piece of oilcloth, and from it four bags of
stout Manila paper, 6Ax3J inches, holding about eight
ounces, are filled. In the United States glass bottles
are preferred, and they are certainly much better
suited to guard against contamination of the sample,
but, as they can not be transmitted through the
Mexican mails, and express offices are not plentiful in
Mexico, and, finally, because glass is dear, paper bags
have become the rule. Three samples are sent to
the assay office of the works, and one is given to the
representative of the ore vendor. Of the samples
sent to the assay office one is destined for the use of
the assayer, one for the chemist and the third one
for the umpire. The latter and the ore vendor's sam-
ples are sealed. After use, the samples pertaining
to the works are preserved until the ore has been
settled for and gone through the furnaces. Umpire
samples are kept longer, unless required to settle
differences between purchaser and vendor, in which
case the assayer elected by both as umpire receives
them.
But it is not the ores alone which the sampler has
to look after ; there are other materials and second-
ary products which require sampling — coal, coke,
limestone, iron ore, matte, speiss and barrings (fur-
nace accretions) — and bullion purchased from small
smelters.
Coal is only sampled when a new kind is received,
or when a deterioration in quality is suspected or
confirmed ; it is analyzed for carbon, ash and volatile
matter.
Coke is sampled regularly, moisture samples and
laboratory samples being taken from every car arriv-
ing at the works. When the last of a shipload has
come in, the coke sample is cut down like that of an
ore and analyzed for volatile matter, fixed carbon and
ash. Sulphur is usually not determined, as the small
quantities present in coke do not affect either the
smelting process or the product. The volatile mat-
ter, however, is supposed to have an important bear-
ing upon the reducing power of coke. Some metal-
lurgists condemn a coke containing over 2% of gaseous
matter.
Limestone is sampled and analyzed only once in a
great while, or, if a new kind is received which should
be unloaded by itself.
Iron ore, pure and simple, was used only in blowing
in to the extent of less than a ton. Its contents in
iron and silica are known.
Matte is weighed and sampled every month while
being run through the mill preparatory to the roast-
ing operation, and again after coming out of the
roasters. The matte is designated by the name of
the month in which it is produced.
Speiss is weighed for the purpose of the monthly
cut-off or inventory taking, but sampled and assayed
only when produced in quantity. Its contents do not
vary much in one and the same place.
Barrings, after picking out coke, large lumps of
limestone and firebrick, are weighed, sampled and
thrown on a lead ore bed. The sample is analyzed
and assayed the same as an ore.
The sample mill occupies a space of 89 feet in
width by 149 feet in length between two sets of
tracks, but is hardly large enough for the constantly
growing business. It is a double building, covered
with an M roof, and has a double wooden floor inside,
with steel plate around the crushers and rolls. The
tracks along the sides of the building are also planked
between the rails, so as to be able to recover any
spilled ore.
A narrow part of the gable end facing toward the
weigh bridge is partitioned off into five compart-
ments, the first of which contains the motive power;
a second the drying oven; a third the bucking room
with the sample grinder; a fourth the office of the
foreman in charge; and the fifth an area or hall be-
tween the latter two. This area is used by the rep-
resentatives of the ore vendors to look at the final
proceedings with their samples, through a window in
the partition. Admittance to the bucking room is
denied them and all unauthorized persons, to pre-
clude the possibility of tampering with the samples.
In the sample mill building there are two 7xl0-inch
crushers set at convenient distances; and in front of
each, facing toward the ore shed, one pair of rolls,
10x16 inches, and another pair 10x20 inches. At the
gable end, facing the roasters, there is a set of ma-
chinery constituting the "sulphide mill." It con-
sists of a 7xl0-inch crusher, a pair of rolls, 14x30
inches, and two cup elevators, one of which lifts the
coarse material from the crusher into the hopper of
the rolls and the other lifts the fine stuff from under
the rolls into a storage bin.
This machinery makes so much dust that it is but
seldom used, and then only for ore and tough ma-
terial. It has no business in a sample mill, but should
be in a place entirely by itself.
For matte crushing a ball mill is used, erected next
to the sulphide mill on the outside of the building. A
machine with 120 steel balls pulverizes from 80 to 100
tons of weathered matte in ten hours fine enough to
roast well. With the toughness of the material the
efficiency of the mill decreases; of copper matte, with
30% copper, only one ton per hour would go through.
Speiss can not be pulverized in it at all; it is simply
converted into ellipsoidal balls which revolve like
steel balls, and are merely polished, not crushed.

An Old Bell.
In the office of C. T. Brown, of the Buckeye M.
Co., with office at Socorro, is found what is alleged to
be the oldest bell in the United States. This historic
bell was made in 1549. In 1680 the church was de-
stroyed by the Indians. In 1734 the bell was dug out
of the ruins of an old church at Gran Quivera, an old
pueblo and Spanish city, said by several Spanish his-
torians to have exceeded 20,000 in population. From
Gran Quivera the bell was brought back to Socorro
and hung in the old San Miguel church.
In 1781 this church at Socorro was destroyed by
Indians and the people driven south to Isleta, near
El Paso. In 1806 a colony of seventy families came
from Belen, on the Rio Grande, and resettled Socorro
and repaired the old church, which stands to this
day. This old bell was again resurrected and placed
in the church. The bell weighs 461 pounds. The
metal used in it came from a mine in Grant county,
called the Santa Rita de Copie. The women added
all their jewelry of silver and gold to it. Chippings
from the old bell have been assayed and it is found
that it is worth over $400 in gold and silver.
This bell was the first to ring on the American
continent, and that on the banks of the Rio Grande.
Seventy years before the Mayflower sailed into Bos-
ton harbor this old bell, with its clear tone, was call-
ing together a brave little band of worshipers with
their weapons of defense in one hand and the cross in
the other. — New Mexican.

Triplex Electric Sinking Pump.
The new triplex electric sinking pump, illustrated
on page 89, produced by the Jeanesville Iron Works
Co., Jeanesville, Pa., is claimed by its manufacturers
to be satisfactorily susceptible of operation by an
electric current direct from a water power situated
miles from the point of application ; that it produces
no heating effect in the shaft, the steam pipe being
entirely eliminated, and when the pump is stopped
there is no waste of current, and when in use current
is consumed in the exact proportion to the work per-
formed.
The design contemplates three single-acting plung-
ers operating from common crank shaft with crank
pins placed 120° apart, the resultant action of these
three plungers being to produce a continuous and
constant stream to the column pipe and tend to re-
duce to a minimum the shock and jar thereon.
The steel crank shaft is driven by two gears fitted
over the discs which form the outside cheeks of the
two end cranks, thus designed to relieve the shaft of
one-half the strain that would be brought upon it if
driven by a single gear at one end.
The motor is on top of the pump frame and con-
nects the crank shaft by gearing to give the desired
speed to pump. The pump frame is made to receive
any make of motor which is adapted to this kind of
work, either direct or three-phase current.

The Cripple Creek Volcano.*
NIMIIKU m. — CONCLUDED.
Eventually (it may have been several thousand
years after the first manifestation of activity) the
volcanic energies became wearied, ami lava ceased
to appear at the .surface. The readjustment of the
earth's crust, at this particular locality, had been ac- I
complished, and a condition of equilibrium supervened.
Tin- lava sank beneath the level of the crater, and.
on cooling, plugged up the conduit. Those who are
engaged in mining at Cripple Greek are aware of the
existence Of numerous large cavities underground,
particularly in the southern part of Bull hill and the
northwestern portion of Battle mountain. In the
Logan mine the orifice of a very large cavity was re-
cently encountered while sinking the shaft. The
sudden flows of water which have embarrassed some
of the mines are due to the unexpected drainage of
such openings. It is worthy of note that these
especially characterize the trachyte phonolite and
those rock masses which represent the lavas ex-
truded last.
After the volcanic energies had declined, there fol-
lowed a long period of smothered activity, evidenced
by geysers and hot springs. Steam continued to
pe, but gently. There was none of the violence
of the earlier period. Heated water accompanied
the steam, instead of fused rock. The hot lava still
existing at greater depth served to give expansive
force to the surface waters which found their way, by
seepage, through the overlying deposits of volcanic
material. The steam and hot water now emitted, at
some spots quietly as a thermal spring and elsewhere
intermittently as a geyser, probably carried a good
deal of mineral matter in solution. A wonderful work
is accomplished in this quiet way, because such ac-
tivities extend over enormous periods of time. Prof.
Judd has shown that the hot spring at Bath, England,
although an apparently unimportant geological
agent, brings daily to the surface 180,000 gallons of
water at a constant temperature of 120° P. This
spring was doing its duty at the time of the Roman
invasion of England, and it is estimated that since
that time it has brought up, in solution, enough
material to form a good sized volcanic cone.
The Cripple Creek district exhibits abundant
evidence of hydrothermal action. This is particularly
the case in the northwestern part of the mining area.
The breccia of the upper parts of Globe and Ironclad
hills, penetrated by the workings of the Deerhorn,
Summit, South Park, Plymouth Rock and other
mines, is much decomposed, and has a loose, crumbly
character. It is seamed to an unusual degree with
irregular fractures, lined with secondary minerals,
among which crystalline gypsum and amorphous
kaolin are the most common. In the Deerhorn shaft
there is evidence of a more definite kind. At a depth
of 240 feet the shaft cuts into a mass of gypsum, and
from that point to the bottom, 575 feet below the
surface, it has been sunk in the midst of what ap-
pears to be a series of extinct thermal springs.
The workings are very extensive and connect with
the adjoining mines. Breccia and tuff compose the
prevailing rock. No distinct dikes are visible near
the Deerhorn shaft; it is probable, judging from the
composition of the breccia at several points, that
several intrusions do exist, but that they have been
so shattered in place as to be scarcely distinguish-
able from the original breccia which surrounds them.
At the third level, and at the succeeding levels, there
are three distinct narrow-pointed cones of compact
white gypsum which, at 15 to 25 feet from their
apex, graduate into chimney-like masses of breccia
cemented by crystalline gypsum. At the sixth level
there is a fourth of these occurrences. Others, which
do not happen to have been intercepted by the
workings of the mine, may exist in the vicinity.
Iron pyrites is found in the gypsum; it occurs as a
scattering of coarse crystals in the upper portion,
and finely disseminated lower down. The white
gypsum carries patches which are stained pink by
fluorite. The surrounding breccia is everywhere
traversed by color bands due to layers of gypsum,
manganese oxides, and iron ocher. Scattered
through the vicinity, but parallel to the group of
columns above described, there are patches, as well
as seams, of fluorite sand, consisting of particles of
crystalline silica stained purple by admixture with
fluorspar. The upper levels also show bands of a
white unctuous clay, named "Chinese talc " by the
miners. This is pure kaolin, derived from the de-
composition of the feldspar in the andesite fragments
composing the bulk of the breccia. The latter is in a
crumbly condition, its character being suggested
by the fact that in driving the levels only a pick is
needed, the ground requiring no blasting. Beyond the
central portion, which has structural lines sympa-
thetic to the arrangement of the columns of gypsum,
the breccia is still stained and disintegrated for a
great distance, and in places exhibits suggestions of
the neighborhood of other thermal conduits.
There can be no doubt as to the nature of these
masses of gypsum. Thermal springs which have be-
come extinguished are marked by just such accumula-
tions of lime, although the carbonate is, under such
circumstances, more common than the sulphate. The

flows of hot water encountered in the deep workings
of the Comstock carried a notable percentage of gyp-
sum. Last April, while examining certain copper
mines near- Hawthorne, in Nevada, the Writer Came
across a group of similar vents, marking the site of
former thermal springs. The conduits, in this ease,
occurred in lime shales, and were still open to a con-
siderable depth, as was proved by dropping stones
into them. They were surrounded by a compact
chimney of carbonate of lime, which had also over-
spread the enclosing rock.
Recurring to the conditions observed in the Deer-
horn shaft, it would seem that the rising hot waters,
in their approach to the surface, were unable to
maintain a defined channel through the breccia higher
than the level marked by the tops of the cones of
gypsum. This might be caused, first, by the fact
that the vapors ascending above the subterranean
springs disintegrated the breccia so as to destroy
its cohesion, and changed it from a compact rock to
loose material. The most potent factor, however,
was probably the diffusion of the ascending waters
into the drainage of the surface, the effect of which
would be encountered at this horizon. The condition
of the breccia and the wide area which has undergone
disintegration favor this view.
It is in accord with facts observed in other regions
that the vents which permitted the emission of lava
flows should be in one part of the volcanic area (in
this case the southern portion) while the escape of
hot waters which marked the time when the volcanic
energies were waning should have occurred in an-
other part, in this case the northern and northeast-
ern. The lava had healed lines of weakness; it had
cemented the fractures produced by the earlier
paroxysmal efforts of the volcano; and therefore
the thermal waters found a better chance of exit
elsewhere. "With the hot waters which found their
way to the surface during the closing period of the
volcanic cycle there were emanations of gas. Sul-
phuretted hydrogen was probably emitted, sulphurous
acid gas, and, in all likelihood, carbonic acid gas, at
one place or at one time. The volcano had now
reached the " solfatara " stage. These acid gases
played an important part in altering the volcanic
rocks, and were, possibly, a factor in the process of
ore deposition which was beginning. The vapor of
hydrofluoric acid was also among the agencies at
work. This is inferred from the large amount of
fluorite, the fluoride of calcium, which occurs all over
the district, and more especially in the gold-bearing
lodes. Fluorite is not found in the lava of Vesuvius.
The action of hydrofluoric acid on feldspars contain-
ing lime would form fluorite. It would also convert
gypsum in a similar way. Pouque has shown that
the action of hydrofluoric acid in the liquid state
is to decompose, first, uncrystalline silicates or
glasses, then fieldspar and other acid silicates,
then quartz, and lastly, basic silicates. Whether the
vapor of hydrofluoric acid would act in the same way
is uncertain, although it is possible that in this case
quartz might be attacked in preference to the feld-
spar. This is a matter of interest, because in ex-
amining specimens of granite which have been con-
verted into ore (by the addition of gold-bearing tel-
lurides) it is observable that the original quartz of
the granite has been attacked while the orthoclase
remains comparatively fresh.
This last stage of the Cripple Creek volcano is of
great importance to the mining geology of the region.
It extended over an enormous period, coinciding,
roughly speaking, with that which is ascribed the first
evidence of the existence of the human genus, and it
afforded, loan unusual degree, those particular condi-
tions which are considered to favor the deposition of
preciousores, During this time, also, the breccia, with
its finer portions, the tuff, became solidified. The pres-
sure of the overlying masses of lava which at one
time covered it, and the chemical solutions, which de-
posited fresh crystalline substances in the inter-
spaces, converted the scoriaceous material into a
compact mass, which eventually became solid rock
as we now see it. The cooling of the intrusive bodies
of lava caused them to contract, and thus developed
lines of weakness along which the energies of the
volcanic center developed fractures permitting the
subsequent prolonged circulation of underground wa-
ters. The readjustment of this particular portion of
the earth's exterior, which followed the cessation of
volcanic eruptions, and the partial settling of the en-
tire mass forming the Cripple Creek volcano, must
have formed an extensive system of ruptures, which
afforded lines of maximum porosity along which the
gold-bearing solutions found passageways. Thus the
hot waters which are supposed to dissolve out the
metals from the deep-seated rocks were permitted to
ascend toward the surface, where the release from
pressure and the lowering of temperature forced
them to precipitate their contents.
The activity of the geysers ceased; the warmth of
the water bubbling from the springs gradually dimin-
ished; and at length the last vestige of the volcanic
fires passed away. The mountain became as cold as
the snow which mantled it each winter, and as still as
the darkness enshrouding it nightly.
A Note on Hand Concentration Tests.*
By Walter McDermott.
In making a hand concentration test a good deal of
skill is required to obtain a clean separation of min-
eral from gangue. The nearest to perfect work in
this line is done by Cornish tin dressers on a vanning
shovel, but few engineers have the practice and skill
to obtain equally good results. Granting that the
necessary knack is attained of throwing up the
coarser particles of mineral from the waste, and of
washing the latter back from the finest slime min-
eral, the difficulty remains of a practical separation
of the two products for weighing and assaying. It
is usual to wash the light waste off the shovel,
placque, pan, batea or other surface employed, and it
is here that special skill is required to prevent loss of
fine mineral, and a consequent necessity for treating
and retreating the tailings. To remove the concen-
trate from the waste in anything like a clean condi-
tion is still more difficult by any of the means usually
employed, but Prof. Threlfall has lately called my
attention to an exceedingly simple and effective
method of doing this. An ordinary glass pipette is
drawn down to a fine point, and fitted at the other
end with a short piece of rubber tubing, to be held in
the mouth, and so allow freedom of motion of the
pipette. Having formed a head of mineral, this is
sucked up into the pipette through the fine point
(while the mineral is kept covered with water), and
is then blown out into a separate dish. The opera-
tion of forming a fresh head of mineral and removing
it by the pipette is repeated, until no more concen-
tration can be effected. An extremely fine line of

slime mineral can be thus picked up from the waste.
The small quantity of waste which will be sucked up
with the mineral in removing this can again be read-
ily taken from the concentrates by shaking the latter
up with a little water, washing back the waste, and
using the pipette on this.

Stoping With Machine Drills.
In the issue of September 30, 1899, appeared a
paper with the above title, read at the California
meeting of the American Institute of Mining Engi-
neers by B. L. Thane, Sumdum, Alaska.
In a communication to the secretary, discussing
the paper, V. G. Hills of Cripple Creek, Colo., says:
In continuation of the subject of the performance of
"baby machine drills," presented by Mr. Thane, I
submit the following records of work done with these
drills in the Cripple Creek district of Colorado.
Two years ago the Anchoria-Leland mine began
to use baby drills, and, to make the experiment more
complete, began .by purchasing two machines, of the
same size, but of different make. The little drills
were first used for stoping and upraising, in which
they achieved at once an unqualified success. Soon
after they began to be used for the smaller branch
drifts and prospecting crosscuts, while the large two-
man drills were still used for the main drifts. Now
they have almost entirely superseded the large drills,
since it has been found that they will do any ordinary
work in the mine at less cost, both for labor and for
powder, per ton of rock broken. The large drills,
of course, make more rapid progress ; but it is only
where time is a specially important factor that they
are now used.
The Portland mine, where, until within a year,
only the large machines were used, is now using some
small drills for stoping, and also for drifting.
Mr. Thane speaks of having two men to operate a
baby drill, but in this district the baby machine is
always worked by one man without help. Again, in
Prof. Christy's postscript, the quoted extract from
a letter of Mr. L. T. Seymour, the South African
engineer, mentions a " 2J-inch Little Giant," as
though that were the smallest machine used in that
region. These statements leave some doubt as to
just what Mr. Thane means by "baby drill." To
avoid any such uncertainty as to the present commu-
nication, I will say that the large or two-man drill in
common use at Cripple Creek has a 35 -inch cylinder,
while a few mines employ a 3-inch, and a few, in run-
ning large tunnels, a 3i-inch drill. What we call a
baby drill here has a 2-inch cylinder and uses i-inch
steel for "starters" and i-inch for the long drills.
Such a machine will handle drills 8 feet long, but
holes are usually from 4 to 5 feet, and seldom more
than 6 feet deep.
In this district these drills are always used with a
bar, are commonly spoken of as "one-mandrills,"
and are operated strictly as such. That is to say,
the machine man has no help, either to set up or run
his drill, does his own loading and blasting, and has
to shovel away his own waste sufficiently to make
room for his next set-up.
It is with such a drill, thus operated, that the fol-
lowing records were made : Total length of holes
drilled in one shift of eight hours, 35 to 45 feet ; aver-
age, 39 feet.
Of course, the amount of ore broken or the length
of level driven in a given time or at a given cost de-
pends on the thickness of vein or the size of headings,
as well as the character of rock ; and, therefore, the
length of the drill holes in a given rock is the only
fair test of the efficiency of the drill. But some addi-
tional particulars may be interesting. A man driv-
ing a drift or crosscut, 4 by 7 feet in section, puts in
nine to twelve holes for his shift's work. Records by
the. month, without any allowance for breakdowns,
sickness, holidays, etc., show an average of 4.3 feet
to 4.7 feet per day with two shifts. A man fre-
quently makes 3 feet a shift for many days in succes-
sion. In making an upraise 4 feet wide by 8 feet
long a man averages 2 feet per shift, doing his own
temporary timbering. Regular timbermen follow,
10 to 15 feet behind, providing a safe place to store
the machine, hose, etc., at blasting time.
Shaft sinking with these little drills is illustrated
by the following record: Size of shaft, 17.1 by 8.2
feet ; depth of working, 900 to 1000 feet ; no water.
Two baby drills sank the shaft 5 feet every two days,
the machine men working only one and one-half shifts
in forty-eight hours, and an equal amount of time
being required to remove the waste and put in a 5-
foot set of timbers. Five "muckers," working one
shift, are required to remove the waste. If any one
knows of a record for cheaper sinking in a shaft of
that size and depth, I should like to have it reported.
A company furnishing compressed air for general
distribution in this district charges $2 per large drill
per shift, where only a small number of drills are
used. I understand that there is a considerable dis-
count to mines using a large number. By actual test
at the Anchoria-Leland mine we have found that a
small compressor, which would just operate two 3J-
inch drills, will run five 2-inch drills. Coal costs from
$4.50 to $6 per ton, according to quality.
From the above data the cost of air for drills of
different sizes and under different conditions may be
estimated.
For intelligent comparison of results in mine work-
ing, something of the quality of rock and other con-
ditions must be known. The rock in which the above
work was done is a highly indurated and, in general,
comparatively seamless andesitic breccia, hardness
6 to 7, specific gravity 2.4 to 2.7. Eight hours is a
day's work for miners in the Cripple Creek district.

A Desert Gold nine.
The Free Gold group, formerly the Golden Cross,
is in Cargo Muchacho mountains, 25 miles northwest
of Yuma, 14 miles west of the Colorado river in the
extreme southeastern corner of California. The
group consists of thirty claims; four are being worked
— Golden Cross, Golden Crown, Golden Queen and the
Geucral Miles. The mines are in the Burrounding
mountains, the reduction works and the town of
Hedges are in a valley 250 yards wide in the form of an
amphitheater, opening toward the west and debouch-
ing on the Colorado desert. The mountains are ol
igi us origin, and while not high, present a rugged
and serrated outline against the sky These mines
were discovered by Mr. Walters in 1885*. Kight years
afterward they were owned by .Messrs. Young and
Johnson, who sold them to the Golden Cross 11 < !o.
for *40. Will. The company erected a In stamp mill
and worked on ore from the Golden Queen with good
results. In 1895 the company completed a new 100-
stamp mill and enlarged the pipe line which supplies
water from the Colorado river. In 1897 the Free
Gold M. Co. purchased the property for $1,00(1, 0110
and remodeled machinery, etc.
Every mining district has its peculiarities, and this
one is not an exception to the general rule. There is
but little quartz and the gold is found in micaceous
and hornblendic schists and in pegmatite (graphic
granite). There is also more or less orthoclase,
syenite, diorite, chrysocolla, gneiss, epidote, com-
from both mills average $3 per ton in value and are
cyanided now at a cost of 33 cents, which will be re-
duced bo 3 nts, or less, when the daily capacity is
increased to 1000 tons.
There has been much development work done —
about 12 miles of shafts, tunnels, drifts, crosscuts,
wings, etc. The timbering is square Oregon pine
6x6 and Bx8 inches diameter. In the ledge running
northwest and southeast the ore is higher grade than
that produced in the other claims, which brings the
average to more than $8 per ton ; but, owing to the
easy method of obtaining the ore, which is now being
worked from the south side of the valley, the latter
is considered most profitable. The ore is delivered in
the mill at a cost of 25 cents per ton ; the milling and
all further handling costs 48 cents per ton. The out-
put of bullion from these mines, including that pro-
duced by the cyaniding plant, is about $70,000 per
month. Nearly 170 men are on the payroll, which
reaches about $10,000 per month. They "are whites,
Indians and Mexicans, the latter largely predomi-
nating.
The improvements, including buildings, stamp
mills, cyaniding plant, engines, crushers, pipe line,
machine shops, assay office, etc., cost about
$1,000,000. The machinery of nearly all kinds is of
the best obtainable. For several years the mines
have been in litigation, which it is claimed has cost
the company some $400,000, yet these mines have
paid all expenses of buildings, machinery, litigation,
etc., and are now practically out of debt.
Well-equipped shops for doing all kinds of work
company has in contemplation the addition of another
loo-stamp mill, making 240 stamps in all.— Con-

Copper Alloy for Amalgamating Surface.
At the California meeting ' of the American Asso-
ciation of Mining Engineers a paper was read on
"Plate Amalgamation," by A. J. Clark of I
S. D. In discussion of the subject, II. Van F. Fur-
man of Denver, Colo., in a communication to the
secretary, says that, in the papers and discussions
on copper-plate amalgamation and the accumulation
of amalgam on copper plates, he has noted nothing
regarding the efficiency of copper alloys as amalga-
mating surfaces.
He then quotes from T, K. Rose, who has sug-
gested an alloy to be used for amalgamating plates,
consisting of copper 60%, zinc 40%. Dr. Rose asserts
that this alloy catches the gold well as soon as
the plate is amalgamated, not requiring to be
covered with gold, or silver, amalgam, be-
fore beginning to do good work; that the
amalgamated surface is superficial; the mer-
cury does not sink in so far as into the pure copper
plate, with the result that it is easier to clean up ;
but pointing out that, as the alloy holds little mer-
cury, it can not absorb much gold and must be fre-
quently cleaned. Note is made that the mercury on
such a plate does not " sicken," which may be due to
the electrolytic action of the copper-zinc couple which

mon granitic rocks, etc., found in connection with the
schists and pegmatite, and nearly all carrying some
gold. The seams of pegmatite present a peculiar
appearance as they traverse, in almost every direc-
tion, the dark hornblendic and micaceous formation.
Instead of quartz-filled fissures the gold-bearing rock
is in large deposits and in some places is quarried.
On the day previous to my visit a blast of nearly two
tons of powder was discharged which brought down
about 150,000 tons of rock from the side of the moun-
tain, which was being reduced in the 100-stamp mill
at the rate of 500 tons a day. Owing to the com-
parative softness of the rock it is rapidly reduced,
and it yields an average of $3.10 per ton and at a cost
all told of 73 cents. The proprietors claim to be able
to manipulate $1 ore at a profit.
The tailings have been accumulating from the time
of the erecting of the first stamp mill, and are now
estimated at nearly 1,000,000 tons. From the 100-
stamp mill they have accumulated to a depth of from
40 to 60 feet. The cyanide plant consists of five per-
colating tanks, 45 feet diameter, 5 feet deep, each
holding 320 tons ; two stock -tanks for solution, two
gold tanks and two sump tanks used for the final de-
posit for solutions. There are also 200 individual zinc
boxes and five pumps. The capacity of the plant is
320 tons daily. The tailings are handled entirely by
machinery, are flushed out of the tanks with water
and carried outside the camp through pipes. About
500 tons of tailings are deposited daily. By Septem-
ber the company expects to increase the daily capac-
ity of the cyaniding plant to 1000 tons. The tailings

needed about the mines are found here, with skilled
workmen to conduct them. They include machine
shop for repairs, blacksmith shop, carpenter shop,
mine-timbering shop where all mine timbers are
framed by machinery, driven by steam; all kinds of
needed work in wood and iron is done here except
castings. A dynamo, capacity 500 fifty-candle power,
supplies electric lights for the mines, reduction
works and wherever else needed.
The company owns ten engines, one crusher of 1000
tons capacity and two crushers of 200 tons capacity.
They also have a complete pumping station at the
Colorado river, where a 175 H. P. Corliss engine
forces the water through 14 miles of pipe to a
reservoir which holds 300^000 gallons, 100 feet above
the town. Owing to its extreme dryness, the. ore
requires about 1000 gallons per ton in reducing it.
Wood is used for fuel and is bought by the ton. It is
palo fierro or iron wood, procured on the desert. It
is as hard and as heavy as lignum vita? and looks like
that wood. It is delivered at the mines for $3.75
a ton.
The stamp mills are among the best and the largest
in number of stamps of any in the State. The i00-
| stamp mill runs day and night. It is said to have
lost but eighteen hours in three years. The stamps
have 6J inches drop and crush five tons of ore each
per day of twenty-four hours. They are driven by a
compound Corliss marine engine of 400 H. P., with
four 100 H. P. boilers; an air compressor furnishes
power for the drills. The 40-stamp mill has been idle
for a time awaiting the removal of the accumulated
tailings, when it will be started up again, and the
sets free nascent hydrogen, reducing the compounds
of mercury and other metals which have been formed,
which would seem to make such a plate suitable for
ores containing large amounts of heavy sulphides or
arsenides. Claim is made that the verdigris formed
on copper plates when grease or other impurities are
present in the battery water do not appear when this
alloy is used, and that such discolorations as may oc-
cur thereon can be better removed by a dilute sul-
phuric acid than by potassium cyanide. Dr. Rose
cites the case of the Saxon Mill, New Zealaud, where
the copper plates formerly required seven pounds of
cyanide, costing $2.80 per month, to keep them clean;
while the alloy plates, by which they were replaced,
were kept clean by five pounds of sulphuric acid per
month, costing 50 cents. He notes, however, that in
the treatment of the highly acid ores, which, having
been weathered, contain large quantities of soluble
sulphates, or, where the battery water contained
acids, that the regular copper plate is less affected
than the alloy, over which a scum is rapidly formed
in such a case. In dressing the new alloy plates the
following method is adopted in New Zealand: The
surface of the plate is scoured with fine, clean sand ;
I then it is rinsed with water and washed with a dilute
(1 to 6) solution of sulphuric acid. Mercury is then
applied and rubbed in with a flannel mop, until it wets
the surface of the plate (i. e., amalgamates with it)
in one or more places, after which the mop is given a
circular movement, passing through these spots until
the amalgamation of the surface spreads from them
over the whole plate.

California Petroleum.
At a recent meeting of the Pacific Coast Gas Asso-
ciation in San Francisco, State Mineralogist Cooper
contributed a paper on California petroleum, that,
in addition to the articles furnished by him to the
Mining and Scientific Pkess on the same subject,
contains practical information of general value. In
this last paper Mr. Cooper directs attention to the
fact that petroleum oils from different oil fields of
California differ widely in physical characteristics
and chemical composition. They may contain, chemi-
cally combined, sulphur, oxygen and nitrogen, and in
widely varying amounts, while in some rare instances
these elements may be absent. Oils in the same
stratum and a short distance apart may vary greatly.
Frequently a well when it first yields will give an oil
of a lighter gravity than that which it will yield when
it has been pumped for some time. We may, there-
fore, look upon California petroleum as containing
carbon hydrogen, sulphur, oxygen, nitrogen and other
substances in minute quantities ; these combinations
being great in number and complex. The boiling
points and melting points of the bitumens are altered
very considerably by the presence of sulphur, oxygen
and nitrogen.
California petroleum is a mixture of a large number
of hydrocarbons, and a large number of compounds
containing hydrocarbons combined with sulphur, oxy-
gen, nitrogen and other elements.
All the hydrocarbons and their compounds with
other elements in California crude petroleum are vol-
atile, some such as benzine extremely so, while
asphaltum volatilizes with great slowness. Natural
gas is a volatile part of petroleum. Like coal, the
bitumens, oils and asphaltum, through decomposition,
are constantly giving off carbureted hydrogen.
One of the reasons why California petroleum has
such a high gravity is because the formation in which
it occurs is tilted and broken, permitting the escape
of the gases.
When California petroleum is evaporated by atmos-
pheric influences, the sulphur, oxygen and nitrogen
compounds remain and are concentrated, and, if the
process is continued long enough, solid asphaltum is
formed. After asphaltum is formed evaporation
takes place with exceeding slowness. Heat accel-
erates evaporation. The evaporation from an oil
tank built under ground and kept at a temperature
of 60° Fahr. , is far less than from a tank built above
the ground and exposed to the sun's rays, which may
often reach a temperature of 130° Fahr.
Advantage is taken of the fact that asphaltum is
nearly an unalterable gum to make many construc-
tions in which a plastic and unalterable cement is re-
quired. Usually California petroleum contains from
5% to 9% of sulphur.
Some wells in California produce oils containing
paraffine and are valuable for producing illuminating
oil.
On the Laguna Extension, or Zaca rancho, in Santa
Barbara county, there are large deposits of bitu-
minous sand exposed upon the surface. On any one
of several 20-acre tracts at this place the dimensions
of the exposures of the bituminized sand would show
that it contains 8,000,000 barrels of heavy petroleum
of the consistency of molasses.
To make one barrel of that material must have
taken eight barrels of ordinary petroleum before
evaporation ; so that on each 20-acre tract is now
the remains of 64,000,000 barrels of petroleum oil.
In California, as elsewhere, there are probabilities of
a very small territory producing great quantities of
oil.
Unaltered rocks of California cover an area of over
40,000 square miles. Bitumens occur in all geological
formations, from the plutonic, metamorphic, or
igneous rocks, up to and including the quatenary.
It is found saturating strata of sand and seamed
shale, and as many as ten beds of shale can be seen
on the eroded sides of some of the anticlinal ridges of
the Coast Range. These sand beds are very irregu-
lar as regards their thickness and the distance inter-
vening between them. Some are a few feet in thick-
ness, while others exceed 400 feet, and the shales are
from a few feet to over 500 feet in thickness.
When several sands are to be seen on the side of a
mountain, or when they can be traced upon the sur-
face of the earth by their outcrop, if bituminized at
all, the bitumen will generally be in the geologically
lower beds, and when a sand contains bitumen the
underlying sand beds are also liable to contain bitu-
men.
At the present time nearly all the wells that are
being bored are in the vicinity of surface indications,
to wit : oil seepages, outcrops of bituminous rock and
gas blow-holes, all of which are signs that the reser-
voirs of petroleum are leaking, owing to insufficient
cover. At present the wells are generally shallow,
but they will increase in depth in time, as they have
done in other fields. The day is not far distant when
oil territory will be selected by geologists on account
of favorable structure and position, irrespective of
surface bitumens. The wells in this territory will
have to be drilled to a greater depth, but, when pro-
ductive, will yield light oil.
The large area and the thickness of the unaltered
rock and the great thickness and number of the oil
sands in California causes Mr. Cooper to express the
belief that the yield of oil in California in future years
will be enormous.
A comparison of the consumption of fuel oil with
that of coal shows 3.33 barrels of fuel oil to be equiva-
lent to one ton of good imported coal. Figuring oil
at $1.40 per barrel and coal at $7.50 per ton in San
Francisco, it shows the cost of oil to be $4.66 as
against $7.50 for its equivalent in coal. Moreover,
the labor required to operate with coal is far
greater than with oil, in many instances being nearly
double.
The perfect cleanliness, of fuel oil and the ease and
simplicity of supply and regulation, makes it a most
desirable substitute for coal. As long as coal remains
at $7.50 per ton in California, it can not be expected
that oil will fall below its present price ; not, at least,
for some time to come.
In the year 1899 there were 1,740,027 tons of coal
imported into the State of California; to supplant this
5,792,238 barrels of oil will be required. As the sup-
ply becomes more permanent the uses of fuel oil will
multiply.
The removal of the gasoline, benzine and illuminating
oil leaves an oil with a high flashing point, which
would be less dangerous to use in a locomotive and
otherwise than a fuel oil of low flashing point. The
removal of the water also improves the oil for fuel
purposes, as it does not have to be evaporated by the
fire.
At present the market value of asphaltum is too
high for it to be economically used for either the
manufacture of gas or for fuel purposes. The large
percentage of sulphur in natural asphaltum or in that
obtained as a residue in the distillation of crude
petroleum, make them an undesirable fuel. During
combustion with oxygen the sulphur combines with
the oxygen to form sulphur dioxide. Sulphur dioxide,
in absorbing water or the vapor of water, changes to
sulphurous acid. By oxidation the sulphurous acid is
changed to sulphuric acid, which may lodge on the
surface of the boiler and attack the iron, forming
sulphate of iron. Through this action the sulphur
contained in the asphalt is a cause of corrosion in
boilers.
Owing to the presence of sulphur, the fuel value of
asphaltum is small when compared with the other
hydrocarbons contained in crude petroleum. The
laboratory and practice show that the distilling,
manipulating and purifying of crude California oil
must be totally dissimilar and different from the
methods in use in Pennsylvania, Canada and else-
where. Most of the crude California oil should be
distilled twice. From experiments made it would
appear that the vapors of the lower hydrocarbons
during distillation are contaminated by the decompo-
sition of the sulphur contained in the higher hydro-
carbons, such decompositions being caused by heat.
The asphalts obtained by the distillation of Califor-
nia petroleum contain from 4% to 1% of sulphur.
California crude petroleum is composed of a num-
bor of hydrocarbons and hydrocarbon compounds
mutually dissolved one within the other and having
different boiling points. Owing to this they can be
fractionally distilled so as to separate them into frac-
tions having the following commercial names and
physical characteristics :

Fifty H. P. "Union" Hoist.
The illustration on page 89 shows the latest im-
proved 50 H. P. double-cylinder, single-drum mining
hoist made by the Union Gas Engine Co. of San
Francisco. One of this size was installed at the
Pacific Coast Borax Works near Daggett, Cal.,
last February, and a duplicate of it has been shipped
to the same party, making nine "Union" hoists
on their property, the first of which was installed in
1889, is still in use, and is said to have been the first
gasoline mining hoist ever built. During the past
week a 50 H. P. " Union " hoist was shipped to the
Ophir Mining & Milling Co., Stateline, Utah, and one
of 25 H. P. to the Vulcan Copper Co., Siegliton,
Nev. The new premises of the company at the cor-
ner of First and Clementina streets, San Francisco,
are already taxed to their utmost capacity by the
demand for the " Union " engines for all purposes.
Vaporizing Attachment for Economical Water Supply for
Water Jackets of Smelting Furnaces.
Two engravings on page 89 accompany this descrip-
tion of a rectangular and round smelting furnace,
respectively, fitted with Nesmith's patent water
vaporizing attachment for the economical use of
jacket water for smelting furnaces. This appliance
was designed originally for a plant that was to oper-
ate in a district where great scarcity of water pre-
vailed, and its success from the start for the purpose
for which it was made, and the improvement in the
even working of the furnace, led to its further
advancement. It is manufactured by the Colorado
Iron Works Co. of Denver, Colo., who indorse and
recommend it for all classes- of water-jacketed fur-
naces, regardless of water supply.
Advantage is taken of the latent heat of steam,
which is 966 heat units, 1 pound of water at 212° F.
absorbing 966 heat units in vaporizing to steam at
212° F. This data is for sea level. Water at the
altitude of 1 mile boils at 202° F. Allowing water to
be supplied to the jackets at 62° and discharged at
202°, there has been absorbed by each pound of
water but 140° of heat units, which is all that it is
possible to get where water instead of steam is dis-
charged from the jackets. If vaporized to steam
from initial temperature of 62°, there is for 1 pound
of water 140 units to boiling, plus 966 units to steam
at 202° indicated temperature, equaling 1106 heat
units, carrying off 966 units of heat in steam from
each pound of water, without making the jackets
any hotter than if they were discharging boiling
water, the proportion of gain or water saved thus
being 966 heat units : 966 + 140 = 1106 +- 140 =
7.9+ , thus using 7.9 times as much water if dis-
charged boiling from the jackets as would be used if
vaporized and discharged as steam, the jacket no
hotter in vaporizing the water to steam than by sim-
ply discharging boiling water from it, using about
one-eighth the amount of water by vaporizing it than
would have been used by discharging it boiling from
the jackets ; and as water is seldom discharged so
hot as 202°, the amount required for vaporization will
fall below one-eighth that usually used for cooling,
and will have kept the jackets at the same tempera-
ture in the one case as in the other.
Instead of taking water direct from source of sup-
ply direct into jackets, a large circular pipe or tank
surrounds the furnace, in connection with or inde-
pendent of the bustle pipe, which receives the entire
supply near its bottom. The lower jackets are con-
nected in their respective positions from the bottom
of this tank ; the jackets are connected with each
other — top, bottom and sides — and the water is
discharged from the top of upper jackets into the
circular tank at a point about its center and just
below the overflow standpipe inside, the tank being
three-fifths full of water all the time. The bottom of
this tank is above the highest water jacket, making
perfect the circulation of water in jackets. A large
pipe is open to the atmosphere, through which the
steam from the tank is exhausted. The overflow pipe
from tank is trapped to prevent the escape of steam
on furnace floor, from, which a very small stream is
allowed to run to waste, visible at all times to work-
men as evidence that a sufficient supply of water is
being received into the furnace, and also that the
appliance is working satisfactorily. A regular
water glass indicator is also placed on the tank,
showing the water level at top of standpipe over-
flow inside as a secondary precaution.
This appliance is considered by its makers to dem-
onstrate that about nine-tenths or more of the water
usually used in a furnace can be dispensed with, and
still further great advantage derived from the uni-
form, even temperature of the jackets at all times
and the diminished liability of their cracking by rea-
son of cold water being discharged into them. The
evenness of the working of the furnace under these
conditions is marked. The jackets are always full of
water at boiling point, but steam is made only in the
vaporizing tank, from which it is discharged into a
tank for condensation and further use, or to the
atmosphere, and which, if the water supply valve is
properly adjusted, need be the only water used.
Pumping expense is thereby greatly reduced.
In the case of the round furnace, from which one of
the engravings is made, the supply water is that
only which comes through the cooling chamber of a
44 H. P. gasoline engine, and is received into the
tank and thence to furnace at practically the boiling
point. The apparatus is considered an important
improvement to any class of water-jacketed furnaces.

ARIZONA.
MAltlCOl'A i iiUNTY.
At Kelvin has been i iccossful
trial teat ol the Ray Copper Co. 'a mill;
the concentrates run from 355j
The railroad is bringing down 300 tons of
ore daily.
At the Phoenix mine, near Phoenix,
s. Huntington will put in a cyanide plant
two Beparator tanks and four
leaching tanks 30 feet in diameter, having
a daily capacity ol l_."i tons of ore. The
ore bavins passed through th" mill will
be pumped Into the separator tanks by a
sand pump. The water will run back to
be us.-d again in milling operations, and
tho contents of the separator tanks will
be removed from them at the bottom and
carried by means of a oar over the teach-
ing tanks and dumped into them.
MOJAVK COUNTY.
(Special Corresponded, i. The Tennes-
see mine is pushing it* shaft as fast as
possible, hoping to get the mill running
as soon as completed and connection made
with the main shaft.
Report is that the O'Connor and Min-
nesota mines and mill, ownod by John
Barry, which have been largo producers
and shippers of ores and concentrates,
have changed hands.
The Silver Age, operated by Mr. Loy,
is reported in ore.
Tho present month will he the banner
month for the Lucky Boy. The whim is
in place and the mine is getting ahead of
present facilities for packing ore down tho
mountain.
Mr. McDuffy is getting out ore from the
Rainbow for shipment.
Fergusson, Plynn & Forgusson are tak-
ing out ore from the Redemption for ship-
ment to tho smelter. The ore carries fair
values in copper, gold and silver. Fer-
gusson & Sons are the owners of this
property! u'so of the Clyde south exten-
sion of same, which they have leased to
others, and work will soon begin.
The Watchman Bros, have made a ship-
ment from their property to Kingman.
Results wero very meager on account of
charges on medium-grade ores. They are
now preparing to ship in carload lots.
There are other properties working in a
small way which may turn out mines in
the future. What is wanted hero is min-
ing capital, not ranchers, who are afraid
to develop unless a prospect gives two dol-
lars for one invested.

COLORADO.
(Special Correspondence). — A review of
the movement of ore during the months
of June and July from the various dis-
tricts of the State, and in the State as a
whole, shows a perceptible falling off of
shipments, as compared with those of six
months ago. The one factor responsible
for reduced production in Leadville, Aspen
and Creede is the decline in the price of
lead. That metal, at the price that pre-
vailed before the decline, constituted the
redeeming element in the operation of
some of the low-grade properties. In
such mines the percentage of silver is low
and the recent advance in the price of the
latter by no means compensates for the
fall in lead. In Aspen district the ton-
nage has fallen from about 12,000 to a
little over 8,000 per month, while in Lead-
ville there is a marked reduction in the
tonnage of the siliceous, oxidized and sul-
phide ores, as well as of zinc-lead sul-
phides, in which lead values preponderate.
About 75,000 to 78,000 tons per month are
produced in the latter camp, of which
about 30,000 tons are treated by local
plants and about 46,000 to 48,000 tons
shipped out.
Shipments from the San Juan districts
hold very uniform, there being no per-
ceptible falling off from their regular ton-
aage. The bulk of shipments from that
section is in concentrate form, in which
lead values aro important, but in which
gold is chief, as regards tho more im-
portant producers.
The falling off of Cripple Creek's ton-
nago of about 33% is due to entirely dif-
ferent causes, as virtually neither lead nor
silver are produced there. The smelting
oro from that district is now running at
the rate of about 8000 or 9000 tons per
month, the falling off being due largely to
the necessary curtailment on the part of
various big mines, pending the installa-
tion of new plants of machinery and the
delays resulting from various reorganiza-
tions and consolidations. The same
causes apply to reduced shipments to the
chlorination and cyanide plants; and, in
addition, it may be cited that, with tho
rapidly increasing capacity of the mills of
that class, miners who have largo reserves
of milling ore think lower treatment
charges and lower freight rates are in
sight. Wascott.
Denver, July 17.
The Denver & Rio Grande Railway Co.

(Special Correspondence). — The ore ton-
nage shipped from Georgetown is not up
to that of a year ago, though the grade
continues characteristically high. Infor-
mation obtained at the samplers indicate
that about 700 tons per month are shipped
out, which averages about 195 ounces sil-
ver, 17% lead and ,',?„ ounce gold. The
two distinctly lead mines of the district
are the Stevens and the Mendota, the
others being more of the nature of gold
and silver producers. A recent shipment
of Stevens ore ran 73% lead. The Aliunda
is keeping up a fair record of lead and sil-
ver. The Centennial, a gold, silver, lead
and copper property; the Griffith, of same
character; Big Indian, silver, gold and
copper; Cory City, silver, lead and gold ;
the Pelican-Dives, Pay Rock, Seven
Thirty, Bismarck, Dunderburg and Fros-
burg, producers of silver, gold and lead,
are all operating.
On Democrat mountain the mines work-
ing are the Astor-Scepter, Sunburst, Sil-
ver Glance, Polar Star, New Boston, Mus-
covite, Mineral Chief and Smith & Wes-
son, all silver-lead producers.

are gold and silver mines, and comprise
the Independence, Johnson, Mendham,
Santiago, Commonwealth, Paymaster,
World's Fair,Three Nations and Marietta.
In Empire district the Tenth Legion,
Gold Dirt, Gold Bug, Conqueror, Gen.
Harrison, Empire City, Atlantic and Sil-
ver Mountain are active, all shipping at
present about 200 tons per month.
At Silver Creek the Jo Reynolds and
Nabob yield about fifty tons per month of
silver, gold and lead ore.
The Millington, Bellevue-Hudson, Dic-
tator and Lincoln at Lawson ship about
fifty tons per month.

ginia, Franklin and Lady Franklin, as
well as the Wilkie mill on Clear creek and
the Allen mill on Chicago creek. The
Wilkie is operating now at a capacity of
about fifty tons per day and the Allen
mill will be enlarged to sixty tons, both of
which are expected to operate on ores
from the group of mines mentioned. The
present tonnage handled at the Wilkie
mill comes from the Crown Point & Vir-
ginia. The lower levels of the latter are
expected to be in condition to produce by
August. On the Franklin group a tunnel
which has been driven 800 feet will be ex-
tended 600 feet farther and a shaft will be
sunk from the surface. W. H. Knowles

six teams hauling ore to Grant's Pass and
have sent four carloads to the Selby
Smelting Works, Vallejo, Cal.
The Alexander & Bent placer mine on
Rogue river, 25 miles below Grants Pass,
containing 510 acres of land and extending
3£ miles along an ancient channel, is re-
ported sold to Chicago men for $100,000.
The A. & B. mine has been operated at a
profit for years. It was described and il-
lustrated at great length in the issue of
April 21, 1900. Its water supply is taken
out of the west fork of Galice creek, in a 7-
mile ditch, and gives a pressure of 350 to
400 feet at the mine. The bank is 80 to
150 feet high, the gold being principally in
a stratum of blue gravel at the bedrock, 6
to 12 feet deep. The mine is well equipped
with pipe and giants, a sawmill furnishing
the necessary flume lumber.

SALT LAKE COUNTY.
The Highland Boy at Bingham has
shipped copper, gold and silver bullion to
the refinery at Perth Amboy, New Jersey,
since June 13, 1899, a total of about 700,000
pounds. Assuming that this has brought
the company an average of 16 cents a
pound, the Tribune figures the gross earn-
ing of the Highland Boy Co. during the
past thirteen months to have reached a
total of over $1,100,000, or an average of
$90,000 per month. Jos. Dederich has the
contract for the erection of the steel struc-
ture, this part of the enlargement alone
requiring nearly 1,000,000 pounds of steel,
the delivery of which • is promised in Sep-
tember.

BRITISH COLUMBIA.
(Special Correspondence). — The Ander-
derson Lake or McGillvery Creek mining
camp, on the northwest side of Anderson
lake, 10 miles from its eastern end, in Lil-
looet district, is a promising quartz mining
section. (See map, page 93.) Many claims
have been located and much prospecting
work done, principally by local men, who
are trying to cover too much ground for
the capital at their disposal. The Ander-
son Lake M. Co.'s property is opened by
tunnels, the lower tunnel in over 300 feet.
The ledge averages 10 feet wide. There
are two upraises, one 100 feet, the other
150 feet, both in pay ore ; 250 feet higher
up the mountain is tunnel No. 2, and 250
feet higher tunnel No. 3. Fifty feet below
the level of the lower or main tunnel is a
ditch, furnishing water power for a 10-
stamp mill. The rock is delivered from
the cars in the lower tunnel into an ore
bin, thence by the tramway in self-dump-
ing cars onto the grizzly and to the rock
crusher and ore bin at the mill, thence by
automatic ore feeders to the mortars and
out over 4xl6-foot silvered copper amal-
gamation plates. There are no concentra-
tors in yet. The building is large enough
for twenty stamps. Ten stamps are now
dropping ; mortar blocks are set for ten
more, and the power, rock crusher, etc.,
of sufficient capacity to run the additional
stamps, so that the cost of doubling the
capacity of the mill will not be great.
Two and one-half tons per stamp are
worked daily. The altitude of the mill is
3400 feet; lower tunnel of mine, 3850 feet —
3100 feet above the lake. The mine is
reached from the lake by a zigzag sled
trail, 4J miles long. All machinery and
supplies have to be sledded or packed up
this trail. The average temperature in
the mill in daytime during June was 47°
F., and much cooler at night. The tem-
perature of the water used in the mill is
45° F. The company has engaged a super-
intendent from Butte, Montana. The
lakes are about 1 mile wide and over 20
miles long each. The banks are moun-
tains 5000 or 6000 feet high, almost verti-
cal in places, here and there ribbed with
dashing, foaming streams coming from
the snow, looking like ribbons 1 foot wide,

Aodorson Lake, July 10.
The Britannia copper property on Howe
sound, operated by H. C. Walters, is
bonded by the B. A. Corporation, which
owns the Le Hoi and War Eagle mines.
The figure of purchase is placed at $1,500,-
000: first payment of $50,000 falls due Au-
gust 17th, and on the 17th days of each
month thereafter for six months $50,000 is
to bo paid. For tho noxt succeeding three
months tho payments will be $100,000
each. At the expiration of twelve months
tho bond will bo cancelled by the payment
of the remaining $900,000. Until the 17th
of August the B. A. Corporation has
merely an option upon the property, the
bond not boing a working one. Upon tho
payment of the first $50,000 the sale will
be practically comploted. Meanwhilo the
engineers of the B. A. Corporation will
examino tho property.
H. W. C. Jackson of the Rossland
board of trade says the mines of Rossland
at the prosont time are giving employ-
ment to 1200 men (eight-hour shifts) at an
average wage of nearly $100 per month,
and the shipments of ore are averaging
over 4500 tons por week, of an average
value of $10.50 per ton, at an average
profit, clear of all expenses, including de-
velopment, of $8.50 per ton. By the first
of December he estimates that about 2500
men will be employed in the mines of
Rossland and the average shipment 14,000
tons per week. The present population
of Rossland is about 8000.
NEW ZEALAND.
A gold dredging boom is reported.
Many claims on the West Coast have been
floated; the yield of 1187 ounces for a week
reported by one dredger company will give
further impetus to speculation.
SOUTH AFRICA.
There were 12,314 white mining em-
ployes in the Transvaal in 1898. The av-
erage salary paid amounted to £321 lis,
or £26 10s a month. The average includes
the higher salaries paid. A report by the
State mining engineer for 1898 gives the
following averages as the monthly pay-
ments in that year for the various classes
specified :

It is thought that by Jan. 1, 1901, work
will be resumed. This is a sanguine view.
There will be less difficulty in securing
white labor than in getting native black
labor, the war having demoralized all ex-
isting arrangements.
SPAIN.
The Spanish Council has approved the
contract with the Rothschilds for the sale
of the product of theAlmaden quicksilver
mines on commission for ten years — 1.25%
on the sale price above £8 sterling per
flask, instead of 2% on the sale price
above £6 sterling.
THE KLONDIKE.
The steamship Amur, from the Klon-
dike, brought nearly $1,000,000 in gold
dust and ninety passengers, some of whom
estimate the year's output of the Klon-
dike at $25,000,000. The claims are now
being worked summer and winter. There
is still some grumbling over the 10% roy-
alty, which the miners say makes it im-
possible to work some of the richest claims
at a profit.
Obituary.
H. G. BLASDEL, the first Governor of
the State of Nevada, died at-his residence
in Oakland, Cal., on the 26th inst., in the
75th year of his age. Deceased was a pio-
neer on this coast, a man of unusual abil-
ity, of herculean stature and great vital-
ity. He was known and respected by
many who admired him for his sterling
qualities. He was not great, but good ;
not fast, but sure ; not brilliant, but solid.
He was a good citizen, a faithful officer,
an honest trustee and a true friend,
whether in the shadow of struggle or the
sunshine of victory.

Vista mine, Sonora, Mexico, operated by
an English company.
California State Mineralogist
Cooper has returned to San Francisco
from southern California.
A. C. Stock has been appointed man-
ager of tho Rhodes Marsh Salt & Borax
Works, Hawthorne, Nevada.
E. M. Bind of San Francisco has gone
to Durango, Mexico, where he reports
having secured some good properties.
H. P. Waterman of tho Hendrie &
Bolthoff Mfg. & Supply Co., Denver,

France, by J. B. DeLamar.
D. E. Bigelow has returned to San
Francisco from Weaver, Arizona, where
he put in a 40-stamp mill built by the
Union Iron Works for the Octave M. Co.
The entire establishment cost $125,000.
N. C. Ray of Coulterville, Cal., is talked
of there for the legislature. Though un-
acquainted with his politics, which is im-
material, the fact that he is a prominent
mining engineer makes this paper sug-
gest that members of that profession in
the California legislature would be good
for the mining industry, and, possibly,
good for the legislature.
Commercial Paragraphs.
The Crown G. M. Co.'s new process for
sizing and concentrating dry ores can be
seen at the works, No. 23 Stevenson
street, San Francisco. This is a new and
scientific system for handling dry and re-
fractory ores that deserves the careful
attention of practical mining men. An
inspection is invited.
The plant of the Colorado Iron Works
at Denver, Colo., was considerably dam-
aged by fire on the 15th inst.; but, with
the exception of the steam hammer and
forging department, work was not seri-
ously interrupted. President Nesmith
states that the steam hammer and forging
equipment will be thoroughly replaced by
August and that a steel and brick fire-
proof building will at once replace the
wooden building destroyed.
The Gillette-Herzog Mfg. Co., now a
part of the American Bridge Co. consoli-
dation, have the contract to furnish and
erect the structural steel for the smelter
of the Santa Fe G. & C. Co. at San Pedro,
N. M., which will include a power-house
and blower-house. The same company
also have contracts for similar work for
the Rocky Mountain smelter at Florence,
Colo. Their Denver representative also
reports the erection of a steel gallows-
frame for the Copper Queen Co. at Bis-
bee, Ariz.
Geo. W. Pennington & Sons, manu-
facturers of the Pennington steel shoes
and dies, are now in their new works at
the corner of Montgomery and Chestnut
Sts., San Francisco, Cal. They have put
in two of the largest steam hammers west
of the Rocky mountains and several of
smaller size. This more than doubles
their former capacity and also enables
them to handle a larger class of forgings
than heretofore. The steel shoes and dies
made by this firm are of high quality and
in extensive use. The old works at
218-220 Folsom St. are retained as a branch
of the new works.

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co.'s Scien-
tific Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Traveling Harvester.— No. 653,465.
July 10, 1900. Daniel Best, San Leandro,
Cal. The object of this invention is to
provide improvements in that class of ma-
chines known as traveling harvesters, in
which the grain is cut, delivered to the
thrashing cylinder, thrashed, separated
and cleaned in continuous operations. The
ininvention consists in improved means for
connecting the header portion with the
thrashing machine frame, and in means
for transmitting power from the driving
parts of a thrashing machine portion to
drive the sickle carrying belt or draper
reel and various parts of the header
mechanism. The connection between the
header frame and the thrashing machine
frame is effected by means of hooks upon
one part and pins upon the adjacent part
with which they engage and means for
retaining them normally in position, but
by which they can be easily released to
disengage and separate the parts. In or-
der to transmit power from the thrashing
machine portion to the header to drive
the sickle reel belts, etc., I employ a flex-
ible belt or chain transmission with suit-
able guide and direction pulleys or sprock-
ets so that whatever the change is in posi-
tion between the two parts of the machine,
the power will always be properly trans-
mitted from one part to the other.
Safety Lock for Harvesters. —
No. 653,817. July 17, 1900. M. G. Mor-
gan, Dixon, Cal. The object of this in-
vention is to render harvesters and like
large traveling machinery safe against ac-
cidents by reason of runaways. The in-
vention consists of shoes with devices by
which they are normally suspended in
front of the main bearing wheels. A lever
or like mechanism is connected with the
suspending devices, so that if the team
attempts to run away or the machine be-
comes unmanageable, these shoes may
be dropped upon the ground in front of
the wheels which run up on the shoes, so
that the whole machine is supported upon
the shoes and the wheels cannot revolve.
In order to hold the shoes in place beneath
the wheels they are connected with some
part of the frame by stout chains which
are only long enough to allow the wheels
to roll up on the shoes where the latter
are held in place.

Catalogues Received.
The S. H. Supply Co., Denver, Colo.,
have issued a carefully prepared catalogue
(No. 27) giving cuts, descriptions and
prices of machines, tools and supplies
which they have for sale, and which per-
tain mainly to mine and mill equipment.
The 1900 "catalog" of the Keystone
Driller Co., received this week, is in reality
a- treatise on drilling, in plain language,
well illustrated, and so put before the
reader as to thoroughly convince him that
the people who put out that "catalog"
know what they are talking about, and,
probably, know something about how a
good drilling machine should be made. In
several ways this "catalog "is the best
trade treatise received at this office this
month. In some regards it is a model.
Anyone who has any notion of drilling a
hole in the ground for any purpose would
do well to send for a copy to the Keystone
Driller Co., Beaver Falls, Pa.

CROWN GOLD MILLING CO.
Manufacturers of the "CROWN" CONCENTRATOR and CROWN
ORE SIZER. A dry process of sizing and concentrating ore, sand or
gravel. Designed to accord fully with the laws of specific gravity,
and especially adapted to refractory ore or localities where there is
no water.
(ST! The chief claims for the Crown Concentrator are that it occupies
less floor space and has nearly four times the capacity of any wet
concentrator; that it will concentrate ores containing base and refrac-
tory metals that ordinarily slime and carry off values; that it effects
a saving of values far above the ordinary methods of concentration.

THE DODD CONCENTRATING TABLE,
which we illustrate herewith, is the latest and most improved machine of this class now made.
This type of machine is so well known that little or no description is required. It is spe-
cially adapted for ores carrying a heavy percentage of sulphurets; has a large capacity and effects
a clean separation.
The operating mechanism can be easily adjusted to meet the requirements of any character
or condition of ore; it is simple, durable and efficient, and gives universal satisfaction.

THE GRIFFIN
THREE ROLLER
MI
The Griffin Throe Roller Ore Mill is a simp.y constructed Mill, suitable for working all kinds of ores that
require uniformly fine crushing by Dm w.t process. This Mill is a modification of the well-known Chilian
Mill, but the rollers run upon a crushing ring or die, which is Inclined inwardly at an anglo of about 30 degrees,
the rollers thomsclvcs also being inclined to the central shaft of the Mill, thus utilizing the centrifugal force,
as the weight of the rollers themselves as a crushing agent. The Griffin Throe Roller Ore Mill is there-
fore a Mill of great strength, and has few woaring parts. We construct thrso Mills with extreme care, using
only the best of raw materials, which are most carefully worked by men who are specialists as mill builders.
We Bell the Griffin Ore Mill on its determined morits, and will gladly supply full information regarding it to
any one.

FOUR and SIX-FOOT FRUE VANNERS
With Brownell "Patent Lip" Flange Belts.
STANDARD MACHINE OF THE WORLD.
When a Concentrator like the Frue Vanner has been on the market nearly two decades, and the sales have constantly
Increased, it is safe to say it is the "Standard Machine of the World." More Frue Vanners have been sold during tho last
twelve months than for the same period at any time during the history of the maohine. Practical mining men in all parts of
the world where mining is carried on will testify as to its merits. It Is the " standard " which all competitors are trying to
imitate.
The results obtained by this machine are the " acme" of concentration, and several cheap and untried machines that
have lately come on the market compare by it. The manufacturers will tell you that they are "just as good, and
cheaper," etc. The facts are that no other concentrator made has an equal capacity, or will yield as clean a concentrate
with as small loss in the tailings as the Frue Vanner. The amount saved from the lower first cost of an inferior machine
counts little in the year's results, when compared with the increased output from a Frue. This machine not only gives bet-
ter results at both ends of the belt (i. e., clean product and poor tailings), but is operated at less expense and requires less
attention than any other machine on the market. At the Alaska-Treadwell mine, where they have ordered over 350 Frue
Vanners, one man attends 48 machines for 12-hour shift.

For Eastern Readers.
With the exception of the Comstock
shares there is tittle jmi >Iii- buying
or selling oi mining stock in California.
Ordinarily, men work the mines instead
of the street. Inquiries received from
Eastern investors indicate thai con-
siderable quiel traffic is going on in
mining stock in sundry localities easl of
the Missouri river. So much has been
said herein on ihis subject that nothing
can be added that would be new, but
there is a point raised in a recent in-
quiry that deserves notice. The ques-
tion asked is as to the relative value of
investment in mining stock as com-
pared with stock in a manufacturing or
similar industrial enterprise.
Ordinarily, the difference is in the
fact that, as the term is generally used,
mining stock does not "earn" money
as Stock investment in other industrial
enterprises. A mining investment
differs from any other in having its
profits derived from what is really its
capital — the ore in the mine. Dividend-
paying shares in a railroad, a factory,
a bank, a mercantile concern or any
other similar form of corporate busi-
ness draw their profits from the pro-
ceeds or result of the operations of the
business, and, without reference to the
capital itself, which is assumed to re-
main intact, and, with due allowance
for contingencies and deterioration, can

so continue on indefinitely. In a mine
every dollar of profit represents so
much taken from the mine itself, which
practically represents the capital of
the concern.- The earning power of an
industrial enterprise may be perpetual.
"When the mine gives out, its capital is
exhausted; and as it is only from this
source that dividends can be paid, they
cease with the working out of the mine.
There are many mines that may be
considered as good permanent dividend-
paying investments as can be found,
and furnishing far better and higher
dividends on the amount invested than
could be secured by the placing of a
similar sum in any other way; but the
stock in those mines is not ordinarily
for sale, and, when a block is sold,
there is considerable publicity over it.
Little attention is to be paid to pros-
pectuses in daily papers, or to specious
statements of what is "going" to be
done. There is generally likelihood of
making a good mine by honest and in-
telligent development of a good pros-
pect, and some of the best dividend-
paying mines in the country have been
developed by the co-operative purchase
of mining stock. Under certain cir-
cumstances nothing is a better or surer
investment; but the Eastern investor or
inquirer, for whose benefit this is writ-
ten, should distinguish between business
investment and heedless speculation,

Oil Fuel for Locomotives.
Petroleum possesses superior advantages for loco-
motive fuel compared with coal on the Pacific coast.
For some time the engines on the Southern California
R. R. have used oil fuel, and now the C. P. Ry. en-
gines between San Francisco and Ogden, Utah, are
to be fitted for oil burning. Locality and cost of the
two fuels determine economic value. Some of the
railroads east of the Missouri river get bituminous
coal for $1 per ton. The S. P. Co. pays about $5 per
ton and the S. C. R. R. has paid $8. Some extensive
railway experiments indicate that one pound of oil
used as fuel is equivalent to two pounds of coal; and
that with oil costing 35 cents per gallon, it was equal
in cost to coal at $1 per tori. Accordiug to such
test, oil at that price is the cheaper fuel where coal
costs more than $4 per ton and the dearer where it
costs less. On some roads a fuel is used consisting of
oil gas tar, coal gas tar, creosote oils and petroleum
residues, the engines being fitted to burn either the
above mixture or coal as desired. For such oil use each
injector has two steam supplies — one to an internal
annular jet, which injects the oil fuel in the form of
finely atomized spray through the nozzle, and at the
same time exhausts air through a central tube,
either from the main automatic vacuum brake pipe
or through a series of air heating tubes placed round
the interior of the smoke-box. The second steam
supply is delivered to a ring-blower arranged at the
front of each injector, from which it escapes in small
jets, inducing in regular quantity additional atmos-
pheric air to insure perfect combustion, and at the
same time atomizing the stream of liquid fuel issuing
from the nozzle. These jets also distribute the gases
over all parts of the firebox, and so equalize the flame,
without the aid of firebrick erections, in former sys-
tems, that were preventive of alternate use -of a coal
fire. Taking a month's average run of 3000 miles, the
fuel consumption of an engine so fitted was 11.5
pounds liquid fuel and 11.8 pounds coal per mile; with
coal used exclusively, 35.4 pounds per mile.
The Santa Fe Co. is now arranging to use liquid
fuel on its locomotives between San Francisco and
the Arizona line.
Several California manufacturing establishments
are also fitting their stationary engines for oil fuel.
Coal has been costing San Francisco steam users
about $6 per ton, and it is figured that with oil de-
livered at $1.43 per barrel considerable saving will
be effected.
flore About Jlining Experts.
Some remarks in last week's issue on mining ex-
perts and expert evidence appear to deserve elabora-
tion. What was said last week is so. The sugges-
tion that the court have an expert of its own is con-
sidered in line with present requirements.
The custom or practice of admitting expert testi-
mony is not so ancient as to be endowed with the
traditionary homage accorded to precedent, and
even if it were, we, here, in the west half of America,
who believe that the law was made for man and not
man for the law, could abolish or change the present
system to the more equitable one of having the court
and not the lawyers or litigants furnish expert testi-
mony.
Everywhere are being tried cases between mining
companies, sometimes involving millions, before courts
where may be called in two, ofttimes antagonistic, sets
of expert statements by mining engineers and ex-
perts and some who can lay no just claim to either
title. Some of these experts seem to go on the stand
feeling that they have been retained by their em-
ployers and that, like other men, their first duty is to
earn their fee and give value received for the re-
tainer. That frame of mind, however satisfactory to
the employer, is not ordinarily conducive to a fair or
impartial statement of the entire truth, no matter if,
as last week suggested, the expert does not desire to
confuse nor confound the facts and wants to state
the truth as it appears to him.
On the part of the lawyers their efforts seem,
sometimes, to be to try to prove that the expert re-
tained by their side knows all about it, and the ex-
pert retained by the other side knows nothing con-
cerning the matter, each side expecting to grill the
other in cross-examination, and if they can confuse or
mislead the judge or the jury so much the better —
or the worse. Where the expert does not want to
state the truth or is incapacitated by reason of na-
ture, education or knowledge of doing so, it makes
it worse still, as in that celebrated mining case
told of in Denver where the expert had prepared a
map of the underground workings of the property in
dispute, and, having submitted it to the attorneys on
the side for which he was employed, was told by them
that its use would tend to destroy their case, and
gave it as their opinion that his own map would help
to establish the theories and claims of the other side.
" That can easily be fixed," was his alleged answer,
and fixed it was, as the story goes. He sat up all night,
made a new map locating the vein and its direction
differently from what it really was, and next day
when he went into court swore to its correctness.
This is unaccompanied by affidavit and probably is an
exaggeration.
Such stories may be circulated against any class,
no matter how honored or honorable; but anyone
who has had anything to do with mine litigation can
tell how near true it may be in some cases coming
under his personal observation or experience. In-
deed, it is the case that some mining engineers de-
cline to appear as experts, not desiring to have their
motives impugned or their honesty decried. The ex-
pert is not to blame; he goes on the stand and
frequently is not given a free head, but has to answer
nothing but cleverly concocted questions, and, as in all
such cases, the environment goes largely toward deter-
mining what is and what is not admitted as testimony.
It is not the expert but the system which is at fault.
The object of all courts and legal procedure is to
obtain justice, and justice demands that the whole
truth be honestly brought out. It is in order that
where mining litigation comes before the court, that it
be the province and the duty of the judge to determine
upon evidence and inquiry whether a mining expert
offering to testify is so fitted, and, if he be, that he be
not considered or selected as the witness of the one
party or the other, but go as an arbitrator or commis-
sioner; a technical adviser of the court itself; a guide
for the court and the jury in forming correct judg-
ment in the case. What he might be called would be
a secondary matter; if desired he could continue to
be designated a witness, but the suggestion that
that class of information be selected by the court it-
self will probably meet the approval of many mining
experts everywhere who have felt at times that they
were placed in a false position and who, while- as
men of honor desired to place the real facts of the
case before the judge or the jury, found themselves
stultified or restricted by the surrounding circum-
stances. For compensation for his services the
mining expert could be paid by the court out of the
public treasury or have his fee charged to the ex-
pense of the trial, as part of the costs of the case, to
be met by both parties as common expense. This
may seem radical suggestion, but it is our belief that
what is here proposed is what will ultimately come to
pass, to the advancement of justice, decrease in costs
of mining litigation, at least equal recompense to
mining experts as under the present system of fees,
and increased satisfaction to any mine owners or
workers who find themselves required to resort to
litigation.
Holding a Mining Claim.
The locator of a mining claim who fails to do the
required annual assessment, but who resumes work
upon the claim before any other party has made a
location on the same claim, has been given by the
courts a quasi title in cases where another party
had located upon the claim subsequent to the resump-
tion of work by the original locator. The most re-
cent decision on that question that we call to mind
was by Judge Hallett of Colorado. He decided a case
involving that principle in favor of the original loca-
tor. He held that the second locator acquired no
rights by filing on the claim after the first claimant
had recommenced work ; that any rights a " jumper "
might have would begin only with the first stroke of
his pick, and could not be based upon any alleged
neglect or lapse of the previous locator, provided
that such previous locator had resumed work before
the jumper had made his location. Judge Hallett's
decision has not been reversed by any higher court.
His decision in effect is that the annual assessment
work required by law is not for the purpose of keep-
ing alive the title to the claim, but to prevent such
title from collapse ; that it made no difference
whether the annual work in question was done or not,
so long as the first locator had asserted his rights in
the following year before any attempt had been made
to relocate the claim. That is, if a man did not do
the required amount of work up to a certain time his
claim lapsed ; but if, however, he began work on the
claim during the following year, before another loca-
tor had intervened, he re-established his rights, his
location then being practically an original location,
and no other locator could claim title by relating
back any lapse of which the first locator had not
taken advantage in time. The action of the original
locator in such cases is risky and he is liable to have
trouble. If he fail to perform the necessary assess-
ment work his claim is jumpable under the law, and
it were better to take no such chances as those
taken in the case in question. The matter is here
referred to in answer to sundry inquiries on the
subject. _
Increased Gold Production.
An official report from the Bureau of Statistics,
Washington, D. O, shows that the increase in gold
production in this country and elsewhere during the
past few years makes the total gold product of the
half century now ending $6,665,631,000. This is
more than twice as much as during the entire 350
1 years preceding the half century now closing. The
' gold production of the world from 1492 to 1850
amounted to $3,129,720,000, that of the period 1851-
1899 was $6,665,631,000.
The following table, compiled from the estimates of
Adolph Soetbeer and the Director of the U. S. Mint,
shows the gold production of the world by half
century periods from the year 1500 down to the
present time:

THE Congress mine, Arizona, was originally worked

SO FAR as known, the biggest mine blast in California
was fired in 1878, in the Dardanelles mine, Placer county,
moving 500,000 cubic yards gravel ; nineteen tons Jud-
son powder were used — equivalent to about 75,000 pounds
black powder.
When petroleum is talked of, a "barrel" is under-
stood to mean 42 gallons. A wine barrel contains 31 J
gallons and is the standard used when capacity of cis-
terns or tanks is given in barrels. Petroleum will weigh
6J pounds per gallon.
South Dakota law requires that every corporation

The Wetherill magnetic separator is considered a val-

In law a "known" mine is deemed synonymous with
an operated mine. The existence of a mine is not
" known " until ore has been extracted or shown toexist
in sufficient quantity and value to warrant extraction
within the boundaries of the claim located.
In March, 1881, the California Legislature passed a
bill providing for a State hospital and asylum for miners,
and the Governor signed it. The intent was to establish
a hospital for disabled miners ; but no subsequent Legis-
lature has made any appropriation therefor.
Results alone determine the value of a mine. A
property producing $500,000 per year and paying $50,000
annual dividends, with an annual investment of $25,000
in machinery, is not as valuable as one producing $250,-
000 per year, with annual dividends aggregating $75,000.
Gas engine efficiency might be theoretically in-
creased by complicating the construction of the machine,
but the increased friction therein involved would prob-
ably in practice tend to lower the efficiency. The aim
of gas engine builders is to average all efficiencies and to
build as simply as possible without sacrificing essential
features.
In Colorado, so far as known, the Merryweather
mine, on Irwin's peak, Clear Creek Co., at an altitude of
14,405 feet, is the highest in the State. The Sierra
Blanca mine, near Garland, is 14,400 feet above the sea.
The May Lundy mine, Mono Co., at an elevation of 11,-
108 feet, is probably the highest mine now being worked
in California.
Before putting in an electric lighting plant, a town
should first find from other towns' experience how the
municipal ownership idea worked. Usually it works un-
favorably. It is not a question of honesty, but inability.
No town can ordinarily install and continuously run an
electric lighting plant as cheaply as under competent
private ownership.
Zinc is now low in price and but little Colorado zinc
ore is being shipped abroad. Ores under 45% zinc have
little or no commercial value, and do not pay to ship for-
eign. While there have been some shipments made to
foreign smelters, the returns are not reported satisfac-
tory, and the quantity shipped has been largely over-
stated. The foreign smelters are no better equipped for
treating zincy ores than are the United States smelters,
but their coal, labor and supplies cost only about one-
half what ■ ej are
able to apply treatment which would be
tion in this country. Freight rates have been obtained
as low as t$ from Leadvilla tu Swansea and Antwerp;
consequently, the Colorado market is open to them with
little freight discrimination.
THE miners of any locality in C nave a right
to organize a mining district and adopt rules and regula-
tions not in conflict with the State or federal law. They
have the right to create the office of mining recorder for
such district and file location notices in his office. The
policy of such action is not under discussion, but the
right to so legally act exists.

An air-tight suction pipe for a pump can bo produced
from ordinary iron pipe with screwed joints. Use
graphite on the threads, screw them together tightly,
cover the joints with a mixturo of melted tallow and
resin, of such proportion that it will not be brittle when
it cools. It should be put on very hot. When ready for
use plug the end of tho pipe, apply a water pressure of
100 pounds, if possible maintaining it for two hours, and
look for leaks.
Cariionate OF lime will not dissolve in water that
has no carbonic acid in it, but will precipitate. If the
feed water be highly heated in a heater and purifier (by
exhaust steam, for instance), the carbonic acid can be
removed and any carbonate of lime in the water will be
deposited in the purifier, instead of in the boiler, thus
avoiding incrustation of the latter. Sulphate of lime,
however, can not be got rid of in this way, as it will not
precipitate below 300° F.
One barrel unslaked lime weighing 220 pounds will
make 2J barrels stiff lime paste, equal to 0.3 cubic yard.
One barrel of lime paste and three barrels of sand will
make three barrels of mortar, equal to 0.4 cubic yard.
One barrel of unslaked lime will make 6.75 barrels mor-
tar one part lime, three parts sand. Cement weighs 400
pounds gross per barrel, 375 pounds net. One cubic foot
dry cement shaken down weighs 100 pounds and makes
0.63 cubic foot stiff paste, when mixed with 25% to 30%
water.
There are three theories as to the origin of petro-
leum— that it is of animal, vegetable and mineral origin,
tho adherents of each theory adducing what they con-
sider proofs. Opponents of the animal origin theory
have claimed that, if so, nitrogen compounds would be
found therein; and now that asphalt from near the Red
Sea has yielded 2% nitrogen, advocates of the animal
origin theory feel more positive than ever. Meanwhile
those who may uphold the combined vegetable and
mineral origin of the oil may be considered nearest the
truth.
The height of a reservoir bank above the highest
water level is usually 4 feet for low and 6 feet for high
reservoirs. When the depth of water at the side of the
embankment does not exceed 30 feet the top of the bank
may generally be 4 feet above the top water level. With
a depth of from 30 to 50 feet the height should be 5 feet;
and when the depth is 60 feet or over the height should
be 6 feet. Trautwino suggests that the top width be 2
feet plus twice the square root of the height in feet.
The inner slopo should be 21 base to 1 height, and the
outer slope l.'v base to 1 height.
Concerning the "power" of a steam boiler, the word
in that connection is not correctly applied, but is used be-
cause of a custom. The rating of a steam boiler is ex-
pressed in terms of its ability to evaporate a certain
quantity of water into dry steam in a given time. Sim-
ply to say that a boiler has 10 sq. ft. of heating surface
to a hoi'se power, tells nothing and means nothing as to
its evaporative effect. A single engine, having a single
cylinder, 9hould produce a "horse power " upon 30 lbs.
of water evaporated into steam of 70 lbs. gauge pressure;
a compound engine, having two cylinders and work-
ing at from 6 to 10 expansions, will produce a horse
power for an expenditure of 20 lbs. of water ; and a
triple-cylinder engine, working at 16 to 30 expansions,
should give one horse power for every 15 lbs. of water
evaporated into steam per hour, in all of the above cita-
tions. The " power " of a boiler begins and ends with its
ability to evaporate certain quantities of water in a given
time.
Of the substances familiar to everybody, some occur,
under ordinary conditions, in the three states of gas,
liquid and solid. Water, for example, under the usual
pressure of the atmosphere, passes into steam at 100° C,
or 212° F., and freezes at 0° C, or 32° P. If the pressure
is increased, the boiling point rises, and if the pressure is
lowered the boiling point falls accordingly. The pres-
sure and the temperature must both be taken into
account. If the temperature is kept high, as in a steam
boiler, a greater pressure must be exerted to maintain
the water in a liquid state, and if the ordinary tempera-
ture were, on the average, 400° C. higher than it is,
water would he known to us only as a gas. That is,
steam at a temperature above 358° C, or about 759° P.,
cannot be changed to liquid by any pressure, however
great. A similar state of affairs exists for every sub-
stance. That is, there is for every substance some point
which it cannot become liquid, and
lied the critical temperature. Ai.
will be easy or difficult to liquefy, according as its critical
temperature is high or low. Oxygen, whose critical
perature is 118° below zero, resisted all efforts at liquefac-
tion for many years; nitrogen, with a critical tompera-
ture of — 146° C, was still more refractory, and hydro-
gen, whose critical tomporature has not been exactly de-
termined, had tu lie cooled to about 2353, or more, below
the zero of the Centigrade scale before it yielded.
I'm: theoretical velocity with which water flows under
a given head is 8.03 times the square root of the head.
To find tho pressure in pounds per square inch of a col-
umn of water, multiply the height of tho column in feet
by .434, approximately; considor that every foot eleva-
tion is equal to 1 pound pressure per square inch : this
allows for ordinary friction. To find diameter of pump
cylinder to move a given quantity of water per minuto
i loo feet of piston being the standard of speed), divide
number of gallons by 4 ; square root of quotient will be
i er (in inches) of the pump cylinder. To find quan-
tity of water elevated in one minute, running at 100 feet
of piston speed per minute, square diameter of the water
cylinder in inches and multiply by 4. To find the theo-
retical horse power necessary to elevate water to a given
height, multiply total weight of the water in pounds by
the height in feet; divide the product by 33,000; (an
allowance of 25% should he added for water friction,
and a further allowance of 25% for loss in steam cylin-
der.)
The rate of combustion in a furnace is computed by
the pounds of fuel consumed per square foot of grate per
hour. In general practice the rate for a natural draught
is : for anthracite coal, from 7 to 16 pounds ; for bitu-
minous, from 10 to 25 pounds; and with artificial or forced
draught, as by a blower, exhaust blast or steam jet, the
rate may be increased from 30 to 120 pounds. The dimen-
sions or size of coal must be reduced and the depth of the
fire increased directly, as the intensity of the draught is
increased. Temperature of gases at base of chimney or
pipe should be 600°, and fractional resistance of the sur-
face of chimney is as the square of velocity of current of
gases. Ordinarily from 20% to 30% of total heat of com-
bustion is expended in the production of the chimney
draught in a marine boiler, to w.hich is to be added the
losses by incomplete combustion of tho gaseous portion
of the fuel and the dilution of the gases by an excess of
air, making a total of fully 60%. Temperature of a fur-
nace is assumed to range from 1500° to 2000°, and volume
of air required for combustion of one pound of bituminous
coal, together with products of combustion, is 154.81
cubic feet, which, when exposed to above temperature,
makes the volume of heated air at bridge wall from 600
to 750 cubic feet for each pound of coal consumed upon
grate. One square foot of grate will consume on an aver-
age twelve pounds of coal per hour. In calculating horse
power of steam boilers allow for : tubular boilers, 15
square feet of heating surface equivalent to 1 H. P. : Hue
boilers, 12 square feet; cylinder boilers, 10 square feet.
Consumption of fuel averages 7J pounds, or 15 pounds
dry pine wood for every cubic foot of water evaporated.
The Centennial standard is thirty pounds of water evap-
orated per hour from 100° F. at seventy pounds
pressure.
Chloride of gold is readily decomposed by heat,
the decomposition beginning at 180° when the mono-
chlorido is formed, and being completed with the forma-
tion of gold and chlorine at 220° to 230°. Whether dry
or in aqueous solution, the trichloride is also decomposed
by light, gold being deposited in scales in the latter case.
Weak voltaic currents precipitate metallic gold from the
solution of trichloride upon the negative pole. The solu-
tion of trichloride of gold is also decomposed by many
reducing agents, such as organic substances, metals and
protosalts; heating the solution in every case hastens the
decomposition. Organic matter is sometimes present in
considerable quantities iu metalliferous veins, sometimes
as graphite and anthracite. It also occurs in the coloring
matter of fluorspar and smoky quartz. The reduction of
organic matter is assisted by the action of light. Alka-
lies also quicken the action of organic matter. Alkaline
carbonates act on hot solutions, half the gold being pre-
cipitated as hydrate, while the other half remains in
solution in the form of a double chloride of gold and the
alkali. Sulphur, selenium, phosphorus and arsenic all
precipitate gold on boiling the solution of the trichloride.
Many metals reduce chloride of gold, the action being,
of course, more rapid in the case of the most highly elec-
tro-positive metals, such as zinc and iron. Lead some-
times gives fine dendritic plates of gold. Sulphuretted
hydrogen precipitates sulphide of gold from both neutral
and acid solutions, while phosphoretted, arseniuretted
and antimoniuretted hydrogen all precipitate metallic
gold. The lower oxides of nitrogen, nitrous acid, and
many other "ous " acids and oxides effect tho same de-
composition. It is difficult, or, rather, impossible, to say
what agents have in any particular instance been the
cause of precipitation. In the case, however, of metals
and of organic matter some indications occasionally still
exist. Peat, for instance, has been found intermingled
with small masses of nuggetlike pieces of gold, and in a
Dakota mine filaments of gold crystallized on mine tim-
ber soaked in acid waters have been discovered. On a
larger scale the Transvaal offers illustrations in the form
of auriferous veins, the bituminous portions of which are
unusually rich in gold. Of metals as the possible cause
of auriferous precipitation, iron and copper pyrites, stib-
nite, galena, etc., when found associated with gold,
may be enumerated.

The Empire Mines, Past and Present.
NUMBER I.
Written for the Mining and Scientific Press by
George W. Starr, Resident Manager.
Nestled in the foothills of the Sierra Nevada moun-
tains, at an elevation of 2400 feet, the oldest and
best known mining town in the United States —
Grass Valley — flourishes with the vigor of pioneer
days, tempered by a growth of fifty years. Grass
Valley, now a prosperous city of neat homes, gar-
dens, orchards and vineyards, is surrounded by beau-
tiful drives and walks, shaded by magnificent native
pines, oaks, maples and spruces, while the alder, dog-
wood, shrubbery and vines along the banks of its
many brooks help to complete nature's dower to the
place where gold in the quartz was first discovered
in California.
In the autumn of 1849 placers were discovered, fol-
lowed by the discovery of quartz in June, 1850, which
Peabody; Eureka-Idaho (now Maryland mine) ; Lone
Jack, Omaha, Homeward Bound (now Omaha Consol-
idated ; North Star, New York Hill, Rocky Bar,
Massachusetts Hill (now owned by North Star Mines
Co.) ; Ophir Hill, Rush & Laton, Keefe & Judd, Rich
Hill, Magenta, Osborne Hill, Empire, Donahue (now
owned by the Empire mines).
From 1867 the mines were supposed to be " peter-
ing out " and in 1879 Grass Valley was known as a
worked out, dying camp, with but three mines in
active operation, the Idaho, New York Hill and Em-
pire, the first in "bonanza" and the other two in
"borasco." In May, 1880, the New York Hill (now
being reopened by the North Star Mines Co.) closed
down, leaving the fate of the camp with the then
great Idaho and the struggling old Empire. To the
Empire mine Grass Valley owes a debt of lasting
gratitude, for in the history of that mine, more than
to all other circumstances combined, is due Grass Val-
ley's growth from a temporary mining camp to an
attractive city of permanent homes.
In the history of gold mining in California the
Empire stands pre-eminent, not alone for its wealth,
but for what the mine, above all others, has

created no excitement until a man named McKnight,
who had come from Newtown, camped ou the summit
of Gold hill, overlooking Boston ravine (now a portion
of Grass Valley), and there discovered the Gold Hill
ledge (October, 1850), the quartz of which, at its
outcrop, was literally filled with gold, demonstrating
clearly the source of the rich placers.
This discovery set the camp into the wildest excite-
ment and was immediately followed by the discovery
of quartz ledges on Massachusetts hill, Ophir hill and
Rich hill (October, 1850). Other discoveries followed
in rapid succession and many people rushed to Grass
Valley to "peg out" a quartz mining claim, which
was originally 30x40 feet.
What is supposed to be the first quartz mill was
built by two Germans in November, 1850. The
stamps were tree trunks shod with pieces of iron.
This was followed by the Gold Hill mill .in 1851. These
mills nearly proved failures and in 1853 quartz min-
ing had fallen to a low ebb, rising with the rapid evo-
lution of the stamp mill to a flourishing state in 1857.
In 1867 Grass Valley had thirty stamp mills, 284
stamps and 1600 men working. Among the well-
known mines then working were the following : Alli-
son Ranch, Pennsylvania, Norambagua, Gold Hill,
I given in the way of example and earnest, well-
applied endeavor. It is the pioneer in deep min-
ing, and the first to regard Grass Valley mining a
legitimate business, controlled by the same laws and
conditions as should govern a well-managed manufac-
turing establishment.
The writer, when consulting engineer for Barnato
Bros., South Africa, had to refuse many applications
for positions. One, more persistent than usual, re-
ceived a refusal of his application, as follows : "No,
of course, I can not get a position. But I will get
one yet, for I am going to America, to sleep one
night in Grass Valley, that I may be a practical min-
ing engineer." The remark is brought to mind be-
cause of the many formerly connected with the
Empire mine whose names are household words in
the mining world — George D. Roberts, J. W. Gash-
wiler, "William Cliff, Thomas Mein, David Watt,
David McKay, John Hays Hammond, Richard An-
gove, H. A. Tilghman, Cospee Thurston, V. M. Clem-
ent and James D. Hague.
What now constitutes the Empire mines is a con-
solidation into one ownership and management of
what was formerly hundreds of claims. The nucleus
of this amalgamation was the original Empire mine
on Ophir hill, discovered in October, 1850, by George
D. Roberts, and sold with adjoining claims in 1851 to
Woodbury, Park and others, who owned a quartz mill
in Boston ravine known as the Empire mill. In the
spring of 1854 the Empire Mining Co. was incorpo-
rated, additional territory was purchased and opera-
tions commenced on a systematic basis. In 1865-66
new works were erected, at an outlay of nearly
$200,000, including a 30-stamp mill, then one of the
finest in the State. The principal owner and man-
ager at this time was Captain S. W. Lee, who clung
to many of his marine ideas. The interior of the new
mill was ceiled and painted and the superstructure
so designed that it was always known as " the steam-
boat mill." In September, 1870, this mill was de-
stroyed by fire and replaced by a 20-stamp mill.
Mining operations continued until November, 1878,
when, all pay ore in sight being extracted, pumping
was suspended and the main incline, which had
reached a depth of about 1200 feet on the dip of the
ledge, was allowed to fill with water. Work was
then commenced on a new shaft sunk on a parallel
vein, known as Rich Hill ledge, which had been
worked through the Ophir shaft. The product in
free gold from May, 1854, to this period (no record
being obtainable prior to 1854) is as follows :

Copper Alloy for Amalgamating Surface.
NUMBER II.— CONCLUDED.
It is Dr. Rose's opinion that the discoloration on
the alloy plates is prevented by the weak electric
current mentioned above. Aaron testifies that the
same effect can be had when the usual copper plates
are in use by placing them in contact with iron or
some other metal which is positive to copper. The
strips of iron bolted to the top and sides of the plate
are said to be sufficient for the purpose, the copper
being in that case unaffected by the acidity of the
water, which causes oxidation and dissolution of the
iron only.
Mr. Purman goes on to say that any one who visits
the stamp mills of Gilpin and Clear Creek counties in
Colorado, or other localities where sulphide ores are
treated by stamp milling and plate amalgamation,
will notice the tendency of the plates to become dis-
colored. He says that his experience with the sug-
gested alloy plate was more satisfactory than with
the ordinary ones, and that this led him to experi-
ment with plates consisting of aluminum-copper alloy.
"I made three copper-aluminum alloys containing
respectively 5%, 10% and 15% of aluminum, which

were rolled into plates, amalgamated unci subjected
to various tests.
"1 found that these plates, when immersed In the
tailings and water from the creek, suffered practi-
cally no discoloration. 1 tried them also with water
ana freshly broken pyrites; with water and pyrites
which had long been subjected to atmospheric influ-
ences, and with water containing small amounts ol
free acids and free alkalies. In every case they
showed practically no discoloration. The plates were
examined with a magnifying glass, to seen the gold
was readily caught by the amalgamated surface.
The results were BO satisfactory that 1 inquired of
leading manufacturers of rolled copper whether they
could make me a few plates of a copper alloy con
tabling lll"„ of aluminum. They replied that there
was no market for such material, and that they
could not undertake its manufacture."

and boys, handles *Ui> tons of ore a day, equivalent to
forty cars.
Smelters always buy ores f. o. b. the railway sta-
tion nearest to the mine and embody the freight in
the treatment charge. The reason for this is that
tlie smelter will get reduced rates from the railways
according to their volume of business, while a miner
or ore broker will not. In illustration of the terms
on which ores are purchased at Smelter No. 3, I will
here append an open-rate schedule furnished in 1898
to ore sellers shipping from a station on the line of
the Mexican International Railway in the State of
Durango:
Pay for all the silver contained $36.50 a kilo.
Pay for all the gold contained if not less than 3.43
grams per 1000 kilos, (or one-tenth ounce per 21100-
pound ton) HlJI cents U. S. currency per gram.
Pay for 90% of the lead, not under 5%, 53 centavos
per kilo.
Add for excess of iron or manganese over silica 15
centavos per unit.
Deduct 20 centavos for each unit of silica in excess
of iron contents.
Deduct 30 centavos for each per cent of sulphur
over 3, the maximum charge being $4.50 per metric
ton of ore.
Deduct 55 centavos a unit for zinc, if over 8%.
Deduct 55 centavos for each per cent of arsenic,
antimony or baryta over 3%, all three added to-
gether.

Stamp tax has to be paid by the vendor of the ore.
The federal tax of 3% on the gold and silver value
in the ore, as well as the mint tax of 2% on the gold,
are paid by the ore purchasers.
It is hardly necessary to add that large producers
of ore will get much more favorable rates, especially
if they enter into long-time contracts.
Roasting Department. — Ores containing more than
8% of sulphur should be subjected to calcination be-
fore smelting, to avoid an excessive production of
matte and dragging too much silver into the by-
products. Yet it is good policy not to roast ores
very high in silver, but to throw them on a bed with
only a small amount of sulphur in it, whereby the sul-
phur contents of the bed are not materially raised.
Such a bed must be composed, however, of ores with
a loamy gangue, like the ferruginous lead ores from
the vicinity of Monterey ; ores which would allow
the silver ore to sift through the interstices, like
quartzose ore, for instance, would not do. Further-
more, there are sulphide ores with coatings of horn
silver, like "La Paz," from Matehuala, which should
not be roasted, lest chloride of silver bo volatilized.
The largest portion of the roasting ore handled is
concentrates from Pachuca, and tierras (lines) from
Angangueo, which have to be crushed to pass through
a No. 12 mesh screen. For various reasons, the own-
ers of the smelter do not feel inclined to encumber
themselves much with roasting ores. The principal
material to be roasted remains, therefore, the matte
falling at the blast furnaces. The first matte runs
about 23% in sulphur ; the concentrated matte less,
say, 16% or 18%. There are six long-hearth roasting
furnaces (calciners, hand roasters) without fuse box,
which receive their charges from above through a
hopper in the arch at the flue end and are discharged
from opposite sides through two square holes in the
floor near the fire bridge end. The roasted ore is
raked through these holes into wheelbarrows p
under them.
A long-hearth furnace holds six charges of 1000
pounds of matte, or 3500 pounds of Pachuca concen-
trates. The reason why there is such a difference
made in the weight of these materials is of a two-fold
nature. In the first place, the concentrates, being
lighter than the matte, reach almost to the crown of
the arch when spread out in the furnace, and, sec
ondly, the sulphur contents of the former are higher
than those of the latter. The material in the fur-
nace is rabbled every twenty minutes, and a charge
is drawn every four hours. No attempt at llltu K n i ,. r
ation or sintering is made, the material being unsuit-
able for that operation, and the men not skillful
enough to keep their llooi clean, if it were done.
After a charge has been drawn, the discharge holes
are covered with iron plates, and the next charges
are moved forward with paddles, when an empty
space Will !"■ Formed at the Hue end on which a new
charge is dumped from above. The charges are
weighed up in trucks at the bins, and raised upon an
electric lift to a trestle which runs across the fur-
naces at the Hue end and branches off to the feed floor
of a battery of gas producers. In the original roaster
building there are live calciners. Bach set of fur-
naces lias a separate Hue and chimney of ample sec-
tion and a height of 7."> feet. Originally wood was used
for heating the furnaces. It is a splendid material
for- attaining a good roast, on account of its yielding
a long flame. But the constant danger of the wood
pili'.s being set on fire by sparks from passing loco-
motives led to the discontinuance of its use. Different
coals and different grates were tried without satis-
factory results. Three gas producers were erected
with the object of disposing of vast accumulations of
coke waste, each 7 feet diameter by l(i feet high ;
cost, $2460 U. S. currency, f. o. b. factory. They are
connected with the calciners through branches from
an underground main flue, which is curbed with fire-
brick. The ash pits are laid in cement and are kept
filled with water. The steam blast is furnished
through a small pipe connected with the main steam
pipe in the blast furnace building. The steam is wet,
but this is no detriment.
These six furnaces roast seventy-two tons of matte
or sixty-three tons of ore in twenty-four hours, hence
cost of roasting will be :
Matte. Ore.
Labor $1 07 $1 22
Fuel 1 06 1 21
Totals $2 13 $2 43
To this must be added the cost of power for electric
elevators, electric light, tools, repairs, etc., say, 30
cents. This will bring up the cost to, respectively,
$2.43 and $2.73.
After the success of the Taylor producers had been
established, three more were put up, making six in
all. This number could accommodate twelve cal-
ciners, if necessary, yet it would be advisable to have
two producers in reserve.
The main flue was entirely rebuilt, enlarged and
extended over to the new calciners, at the same time
making provision for the probable addition of more
calciners.
The roasted material, as drawn from the furnaces,
is dumped on a cooling floor paved with hard burned
brick and there drenched with water, weighed, sam-
pled and divided into lots, which have to be smelted
away as fast as possible, as the cooling floors are lim-
ited in size. Roasted matte is used advantageously
in replacing part of the iron ore in the blast furnace
charge.
The smelting department is separated by a wide
passage from the engine and boiler house, and in line
with it is the furnace building. In it are ten cupolas,
which are distant 25 feet from center to center of
each other! This is insufficient for large furnaces, as
considerable space between two furnaces is required
to stack up the bullion produced during a shift, and
sometimes more. The smelting department has un-
dergone many changes and is still in a transition
state, as we shall see below. The furnaces are of the
side-feed pattern, are operated with a closed breast,
and provided with syphon tap, except one which is
used for matte smelting. They consist essentially of
four parts — the crucible, the water jackets, the shaft
and the chimney.
The crucible (hearth, sump, well) is enclosed in a
casing formed by eight heavy cast iron plates — the
curb plates — standing on a bottom plate of heavy
boiler iron, not cast iron, with a rim of angle iron
riveted to it, which conforms to the shape of the cas-
ing and keeps the plates in position. The casing, and
hence the bottom plate, forms an elongated octagon.
The curb plates are 3 feet 6 inches high, and consist
of the front or dam plate, the back plate, two side
plates and four angle plates. They are bolted to-
gether through lugs at their sides and are further
firmly held together by a set of binders 23 inches
square. In the center of the upper edge of the front
plate there is a semicircular cavity in which the slag
spout is fitted. In the side plates there is a bowl-
shaped projection in which the lead wells are built up.
To economize in patterns by making them inter-
changeable, founders place this projection in the cen-
ter of the upper edge of the plate. But this is wrong.
The lead well should be placed as near the front plate
as practicable. I located it at one-third of the dis-
between front and back plate from the front
plate ; it should come between two tuyeres. It is
also wrong to detach this projection and bolt it on ;
a great deal of unthought-of trouble will be experi-
enced with such an arrangement.
The crucible is built of firebrick laid in fireclay mor-
tar, and has tapering sides, the dam and long sides
having a steep taper, while the back wall slopes
gently towards the front, and is even made thicker
than the oilier walls to avoid the necessity of locking
up too much bullion. The depth of the crucible may
not be over 27 or 30 inches. Contrary to ancient
practice, no steep (brasque) is used in' shaping the
crucible.
The syphon tap is a channel li inches square in sec-
tion leading from the bottom of the crucible upward
to the lead well ; it does not go up in a straight line.
It is wrong to make the section rectangular, with the
long sides upright. In this case matte will invariably
enter the lead well and clog it. To guard against
the bulging out of the plates by the expansion of the
brick walls, a space of 3 inches is left between plate
and wall, which is tamped out with sand or a mixture
of sand and clay.
The water jackets are resting on the topmost course
of the crucible walls. They are made of cast iron in
symmetric sections, in order to restrict the patterns
to the smallest number. The sides consist of six sec-
tions each, the front and back of two each. In the
side jackets a tuyere opening is cored out, which is
48 inches in diameter on the outside and 35 inches on
the inside facing the fire. The center of the tuyere
opening is 11 inches above the bottom of the water
jackets in the case of the large-sized furnaces, and 13
iuches in the case of the smaller-sized ones. The water
space of the jackets is 6 inches and the thickness of
the wall is 1-inch.

The Griffin Mill.
On this page is illustrated the Griffin three roller
ore mill made by the Bradley Pulverizer Co., 92
State street, Boston, Mass. Of this mill the manu-
facturers say while it " is a modification of the well-
known Chilian mill, the rollers run upon a crushing
ring or die, which is inclined inwardly at an angle of
about 30°, the rollers themselves also being inclined
Griffin Three Roller Ore Mill.
to the central shaft of the mill, thus using the cen-
trifugal force, as well as the weight of the rollers
themselves, as a crushing agent.
"The mill consists of a heavy and substantial bed,
in which is fixed a crushing ring 5 feet in diameter
and 6 inches wide, and inclined inwardly at an angle of
about 30°. Above the bed or pan is a conically shaped
carrier fastened to the main upright driving shaft.
To this carrier are fastened the shafts on which the
crushing rollers rotate, being secured thereto by
rocking heads and trunnions so that the shafts may
move in radial lines.
"The rollers are propelled or driven with an orbital
motion, around and upon a crushing ring or die, and
not only utilize their full weight in crushing the ore
upon the die, but also use all the centrifugal force
developed.
" The material to be crushed is fed by an automat-
ic feeder into a feed chute, and is delivered in a
channel inside of the die. From this point it is carried
around and distributed upon the die by vertical and ad-
justable distributing bars or plows, while the neces-
sary amount of water is being fed into the mill. The
action of the rollers upon the pulp throws it against
the screens, the portion which is sufficiently fine pass-
ing through into a trough outside, from which it is
delivered through the discharge spout.
"The material not fine enough, by action of the
mill, falls back and across the face of the die, and is
thus brought in a satisfactory manner in front of the
crushing rollers.
" The fact that the die is inclined inwardly makes
it possible to procure a much more even distribution
of the material to be crushed than can be done on
either a vertical or horizontal die."

Vibratory Screens.
On this page are depicted an inclined vibratory
screen built almost entirely of steel. The screen is
hung from the structure with a slight incline. The
device may be, however, made to screen on a hori
zontal plane. The material drops into the sen
the head end, and, by reason of the vibrato
incut given the screen by a crank rdnning at i
tain speed, immediately takes an outward movement
towards the end of the screen, the distribution of the
material, after separation, being arranged so that
the tailings are deposited first r .mall chute
near the end of the screen. The lines travel onward
along the floor of the screen trough and fall over the
end, to be used as desired ; the screen plates an
justable.
The vibratory screen and separator is a combina-
ground from the surface down, and even if they had
giants thev could do nothing, as the introduction of
water would cause an expense not warranted by the
output. The lateral gulches arc worked by tunnels,

out the dirt in baskets to be washed in the
ra of the main gulch. Instead of working from
the I" he gulch, the miners commence at the
top and work down, carrying the tailings up hill.
The ground in these dry gulches averages about 16
cents a yard, and is worked at a profit, with all the
handled in this way. The current rate of
s is *3 gold a month, and board, the latter cost-
inK :i a month, making the total expense
t $6 a month for each man. The main gulch is a

tively Hat with a good supply of water. Mr. Mathez
says that while thev did not have time to make a
thorough examination of the main gulch, it is known
to be rich, and with the installation of a modern plant
could be made to pay handsomely.

supported by bar springs connected with the trough
by pivots and at the lower end rigidly fastened to the
structure, set at a certain angle; when motion is
given to the screen by the crank which is placed un-
der the center, the screen oscillates in such a man-
ner that the material is made to travel onward towards

pulley will operate, the screen and spiral conveyor at
the same time. This is accomplished by means of a

to which is attached a link-belt chain which, by
another sprocket and bevel gears, drives the spiral
conveyor. The screen may be made without the re-

Some Mines of China.
A. Mathez, who went to China some months ago,
has returned, and the Denver Republican states that
the party he was with did not have time to go over
the entire field, the Boxer insurrection compelling-
them to suspend operations very soon after arriving
on the ground, but that he. traveled several hundred
miles and made a careful examination of the placers
of Chai-li'rh and of a lode mine at the same place. He
says that the main gulch is rich virgin ground, the
Chinese being unable to work it on account of the wa-
ter. On both sides of this gulch are lateral gulches
above high-water level and from which a considerable
amount of gold is extracted by the primitive methods
of the Chinese. They do not attempt to wash the
fully for many years, but the deepest workings are
not more than 150 feet from the surface. One vein
examined has a body of ore 18 inches wide, carrying
three and one-half ounces of gold and 20% of copper.
The ore is hauled by wagon or pack mules to Tien
Tsin. a distance of 150 miles, at an expense of about
$10 a ton. The ore is generally carried as ballast to
Swansea at a very iow rate, and after all expenses of
mining, transportation aud treatment nets about
$100 a ton. The methods of the Chinese in lode min-
ing are similar to those of some Mexicans, with the
difference that instead of using a notched stick the
Chinese use rough ladders, or make steps in the solid
wall, carrying heavy loads of ore on their backs.
The country is entirely destitute of timber and
though the mine was stoped out to the surface the
crevice was left without any support whatever. They
use a table that in some respects slightly resembles
those in use in this country for concentration, which is
worked by hand, an attendant keeping the pulp
stirred up with a rake; even with this crude appliance
they manage to save 80% of the value contained in
the ore. Mr. Mathez says that after many years'
experience, in the mines of the United States, he has
never seen a district where a mine could be put on
a paying basis at so short a distance below the sur-
face.
No examination of the coal and timber land was
made, but Mr. Mathez went into one coal mine that
is being extensively worked on a seam of 18 inches of
coal, in three different veins of about 6 inches wide.
The coal is reached by an incline with steps in the .
solid rock going to a depth of 80 feet vertically. The
vein is then followed on its incline and the workings
are now about 120 feet below the surface. When
asked why a shaft was not sunk to the coal body, the
operator replied that the cost of hoisting would be
more than the coal is worth. Still, operations on this
mine are conducted at a good profit. Everything in
the way of mining is carried on in the crudest way.
No machinery is used except the table, and the
miners confine their work to the ore alone, taking as
little dead rock as possible. In many places boys
are empkryed to take out ore from veins not more
than 12 inches wide.

Precipitation in Cyaniding.
To the Editor : — Under "Concentrates," in the
issue of June 23, 1900, appeared the following :
The temperature of the cyanide solution has an appre-
ciable effect on precipitation ; many cyanidists say that
at a temperature of 90° F. there are better results than
when it is lower.
I know there is excellent authority for this state-
ment, but my own experience does not confirm it.
Generally speaking, chemical action is more rapid in
warm than in cold solutions ; but, if so with cyanide
solutions, the difference is so slight that I have never
been able to detect it. I have secured as good re-
sults at 33° F. as at 120 F°. With other conditions
right, perfect work can be done with solutions almost
freezing cold.
In the same issue is the following :
It is the opinion of some cyanide experts that, so far as
the chemical part of the process regarding the solution
of gold by cyanide is concerned, there is not much room
for further advance, and that whatever improvement is
made will be largely of a mechanical nature. It is, how-
ever, generally conceded that in the matter of precipita-
tion of gold from the cyanide solution there is yet much
to learn.
While that paragraph might have had the weight
of many authorities back of it a few years ago, the
opposite of the statement is certainly nearer the
truth now.
At the Schmidt & Johns mill, at Silver Star, Mont.,
tailings were treated from half a dozen yards in one
season and royalty was paid to four different owners.
Some of the tailings treated very nicely. Other piles
required the utmost care and skill, and even then it
was not possible to make as good an extraction as one
would wish. Not only was a perfect check kept on
the heads and tails of each vat, but record of the
tonnage of each solution was kept, with its assay
value. At the end of the season the superintendent,
P. C. Waite, tabulated his records, and it was found
that every dollar entering the zinc boxes had been
accounted for. This is not an exceptional record.
Others are making it every day in Montana. It is
made by C. L. Dahler, at the Iron Rod mill, with zinc
shavings on solutions from refractory, slimy tailings.
The files of the Mining and Scientific Press are in
evidence that it is made at the plant of the Montana
Mining Co., Ltd., at Marysville. (See article by
C.W.Merrill, " Notes on the Alleged Shortage in
Cyanide Bullion," Mining and Scientific Press,
July 8, 1899.) When a man's assays show that he
should have over a third of a million dollars in his
clean-ups for the season, and he has every dollar of
it, surely it can not be said that he has "yet much
to learn " in the way of recovering the gold from his
solutions.
But how is it in other parts of the world ? A let-
ter from Alfred James of London to the writer, under
date of April 24, 1900, bears directly on this point,
and I make the following extended extract from it.
He says :
" I have read with much interest your contribution
on ' Successful Precipitation Prom Solutions Weak in
Cyanide ' to the Mining and Scientific Press of
March 24th, and note you state, in a kind reference
to my work, that where I would use ' 1 cubic foot of
zinc shavings to one ton of solution passing through
the extractor each twenty-four hours, less than half
this amount has been in use with us in Montana the
past summer.' It is just possible that in the papers
I have written I did not make myself sufficiently clear
when I stated that 1 cubic foot of zinc shavings to
each ton of solution will treat perhaps the most re-
fractory solutions met with in practice. We have
been treating solutions containing practically no free
cyanide at all — including those derived from the filter
bottoms in the sluicing out of the tailings — with a
practically perfect extraction, the effluent amount-
ing to less than one grain of gold per ton, using less
than half a cubic foot of zinc per ton of solution
treated daily. Our boxes in normal work all over the
world are designed on the basis that three boxes,
each of which has six 1000 cubic inch capacity com-
partments filled with zinc, or 11 cubic feet of zinc in all,
will treat daily forty tons of ordinary solution ; and
this ratio practically applies to the whole of the In-
dian plants, some of which are of quite large capac-
ity, to those in Eastern Asia, and to a large number
of those in South Africa, in New Zealand, in Austra-
lia and elsewhere.
" In writing the paper to which you refer, I had par-
ticularly in view solutions resulting from the contin-
uous treatment of weathered slimes and tailings, and
thus containing a large quantity of soluble salts — at
times even yielding a. faintly acid test. It was as-
serted that such solutions could not be ' treated
effectually with zinc in any quantity, and the particu-
lar object of the paper was to point to the mines of
Johannesburg, where this solution occurred, that
with two boxes in series they could treat even this
solution effectively.
"As a matter of fact, the electrical precipitation
process has now been displaced at the majority of the
mines by zinc precipitation, with the addition of lead
salt. I anticipate, however, that before long they
will discover — provided they do not start the boxes
with fresh zinc— that the lead salt, too, is entirely
unnecessary. They have for some time past been
treating slimes solutions in the Lydenburg district
without the addition of any such salt."
I -would say the trouble is to get enough gold into
solution ; there is no trouble getting it out. Surely,
there are few cyaniders but would like to make a lit-
tle better extraction than they are able to. I would
say there is "much room for further advance re-
garding the solution of gold by cyanide," and that it
is reasonable to suppose that such advance will be
made. I believe there can not be much improvement
in the way of the mechanical part of the process.
Nevertheless, there are difficulties preventing the
cyaniding of certain ores and causing unaccountable
losses with some material which in time, with study
and work, may be overcome. There is room for im-
provement along this line ; but I can not see where
there is possible room for improvement in precipita-
tions when to-day everything is recovered from solu-
tions, clean or foul, and whether containing free
cyanide or otherwise. What more can one ask ?

The Gardner Process.
To the Editor: — The American Copper Mining &
Extraction Co. of Denver, Colo., owns the patent of
the Gardner process of copper extraction, which has
been tested and considerably discussed of late. An
experimental plant to exemplify this method of ex-
traction has been established here by P. M. McCaf-
frey. On July 23, 1900, a special test was made of
148 pounds of partially oxidized copper ore from New
Mexico. After being pulverized to about 20 mesh
the ore was thrown into a small vat and about thirty
gallons of water turned in from an adjacent tank.
Then twenty pounds of sulphuric acid and three
ounces of common salt were added. After agitating
the solution a few minutes a half pint of nitric acid
was added, and a few minutes later about a half
ounce of permanganate of potash ; and during the
agitation, which was kept up for about half an hour,
a considerable quantity of hot water was gradually
introduced. The action of the salt changes part of
the sulphuric acid to hydrochloric acid and that of
the permanganate produces nascent chlorine and
doubtless aids as an oxidizing element. The combina-
tion of hydrochloric and nitric acids forms aqua regia,
a solvent for copper. The resultant solution was
then drawn off into the precipitating tank, contain-
ing a perforated, revolving copper cylinder, the lat-
ter containing about fifteen pounds of scrap iron. The
cylinder was revolved in the solution for twenty min-
utes, during which time the sulphuric acid, which has
a greater affinity for iron than for copper, liberates
the copper and takes up the iron, the copper pre-
cipitates settling to the bottom of the vat. After
the liquid is drawn off the precipitate is scraped into
a drying pan, dried and smelted in a small furnace
and the metallic copper poured off. It is claimed the
liquid, after precipitation, is returned to the solution
tank, to which 15% of the original amount of chemi-
cals is added, and that a second treatment results in
extracting what may have failed to dissolve in the
first treatment. The patentees and promoters of
this method claim for it an adaptability to the treat-
ment of low-grade oxidized copper ores, and that it
might serve as a preparatory process to cyanide
work where the existence of copper in gold ore
proves a hindrance to cyanidation. W. A. Scott.

Relative Heat Efficiency.
To the Editor: — In the statement in the issue of
July 14th that a ton of coal (2000 pounds) has
28,000,000 units of heat while a barrel of petroleum
has 3,500,000, or one-eighth as many, I think no
allowance was made for loss in ash and waste gases
in burning coal, but allowance was made for waste in
burning the oil.
My records show that a general average efficiency
of coal burned direct in forges is 10% secured of the
theoretical value and in burning oil about 75%, so
that such a comparative statement might read like
this:
A ton of coal (2000 pounds) has, theoretically,
28,000,000 heat units, 10% of which are available on
work in forge fires, or 2,800,000 heat units. A barrel
of 42 gallons, or 275 pounds, petroleum has a theo-
retical heating value of 5,775,000 units, 75% of which
are available on work in forge fires, or 4,331,250
units. A barrel of petroleum is equal to a little
over one and one-half tons coal. W. J. Brown.

"Whin" and "Quartzite."
To the Editor: — " Concentrates " recently defined
"whin" as a local name for quartzite, while R. B.
Symington of San Francisco claims the name for ig-
neous dyke rocks. Both appear to be right, as the
term is differently used by different people, and the
Standard Dictionary states that " whin " or " whin-
stone " is a local British word, applied to " any hard,
dark-colored rock," as "basalt, chert or quartzose
sandstone." W. J. S.

Deep flining at the Utica nine,
Angels, Cal.
In the issue of Oct. 7, 1899, appeared an illustrated
article, with the above caption, read by J. H. Collier,
Jr., of Berkeley, Cal., at the Sept., 1899, meeting of
the American Institute of Mining Engineers in San
Francisco, Cal.
In discussion thereof, F. H. Probert, Neudorf, An-
halt, Germany, in a communication to the secretary,
says: I have read with much pleasure Mr. Collier's
valuable paper. But the system of timbering which
he describes as used in the levels, stopes, etc.,
though it must be admitted to be very strong and
safe, seems to me somewhat extravagant. The
amount of timber required every month for such a
system must be enormous, and only where suitable
material could be cheaply obtained would such a plan
be economically practicable.
The first point which strikes me is the unusually
great diameter of the timber employed.
In the mines of Pfaffenberg and Meiseberg, which
are under my supervision, the country rock consists
of argillaceous slates, traversed by innumerable small
fissures or joints, dipping at all angles and striking
to all points of the compass. Undoubtedly this net-
work has been caused by the upheaval of granite
masses in the vicinity. Each fissure is accompanied
by a more or less well-defined gouge or fluccan,
caused by the rubbing together of the slates at or
after the original disturbance. In such a mine the
timbering must be of the very best quality and de-
sign; but we are compelled to exercise economy in
this respect. It is often necessary to timber a level,
both at the top and on both sides, for from 150 to 200
meters. Thurstock timbering, supplemented by pol-
ing, is our general method. The posts are either
round or rectangular, and seldom more than 20 to 25
centimeters in diameter. The foot of each post is set
firmly into the floor of the level, or, when no sound
footing is obtainable, sills are used. The caps are
also either round or square, and of about the same
diameter. When the roof alone needs support, we
simply cut a shallow curved notch in the top of the
post to take the shape of the cap (see Fig. 1); but
when both the roof and sides of the level are in-
secure, we cut the timber as shown in Fig. 2. This

Post and Cap to Support Roof Only.

part of the work is all done underground. The posts
and caps, having been sawn on the -surface into the
previously measured lengths, are then sent to the
working place, and the timbermen, kept exclusively
for this work, cut the notches and fit them together.
Such men are paid at the rate of 2.50 marks (about
62 cents) per shift of ten hours, or, whenever prac-
ticable, by contract, according to work done.
In very loose ground, poling is resorted to. Here
again I am compelled to think that the poles used at
the Utica mine are unnecessarily bulky. Our poles
rarely exceed 2 meters in length and from 15 to 18
centimeters in diameter. They are made of pine,
which is found to be very good for the purpose.
When we encounter running ground, posts and caps
are set up about 1 meter apart, and the whole ground
is made secure in the manner described by Mr.
Collier, the only difference being that we use oak
laths instead of poles. These laths are from 10 to 15
centimeters wide, 4 to 5 thick and 80 to 120 long.
One end is sharpened to allow it to be more easily
driven into its place by blows from a hammer. The

For the permanent timbering of levels, oak is used
wherever possible. It lasts from ten to fifteen years,
whereas pine lasts only four or five years, so that, in
the long run, oak is more economical. It is found,
however, that where there is much water, pine is
better. For the temporary timbering of stopes, pine
is almost always used.
In the stopes, I am of the opinion that much more
could be done with the " deads " than is set forth in
Mr. Collier's paper. If I understand his account, it
implies that a great quantity of such material is ob-
tainable from the driving of levels and the develop-
ment of the ore bodies. Here in the lower Harz
mountains we make use of these "deads" in many
ways. Instead of using timber to make ore chutes
and manways, we employ two men to select the
largest and best pieces of waste rock and to build
with these to the required height, as the stope is
raised, the necessary chutes. (See Fig. 4.) These

men are paid 1.30 marks (about 33 cents) per square
meter of walling. The chutes require practically no
repairs, and are absolutely solid if properly built.
No cement of any sort is used.
Again, the miners themselves have to sort all the
rock and put the ore into the chutes. The " deads "
are stacked up in the form of a wall to support any
loose ground, the fine stuff being used to make a good
floor for the stope. Should a mass of rock become
loose, it is immediately secured by the miners with a
post and cap, until it can be supported by " deads,"
when the post is withdrawn, so that practically no
timber is lost. As the stopes are worked out, the
space below is filled with "deads." We find this
much cheaper than putting in square sets and then
filling in with "deads."
Commissioner Hermann of the General Land Office
has decided to continue for a reasonable time the
suspension of about fifty whole townships in Los
Angeles, San Francisco and Visalia land districts in
California from disposition under the agricultural
laws on representations .that they contain valuable
oil deposits. A thorough inquiry into the true char-
acter of the lands is now in progress. Petitions and
sworn protests have been filed with the General Land
Office setting out that vast areas of non-agricultural
lands in California have every indication of contain-
ing valuable deposits of oil. The land office last Feb-
ruary ordered the suspension of these townships in
view of the controversy over their value as oil lands.
The action is in line with a recent decision of Judge
Ross of the United States Circuit Court for the
Southern District of California affirming the right of
To THE Editor: It seems not
to lia\ e neeuri ed to the authori-
ties on this subject to test tie-
effects of the distilled alcoholic
vapors on tumeric paper. We
find by repeated experiment that
if applied in the following manner
the presence of boracic acid in a
mineral borate is rendered more
certain and delicate, especially
when in traces only.
Boil vigorously in a test tube —
about 2.5 centimeters diameter
and 20 centimeters long — a few
cubic centimeters of wood alcohol (common alcohol will
do also), to which a decigram (.10 gram) more or less,
of the mineral pulverized, and about one-half cubic
centimeter of muriatic acid have been added. While
boiling hold the moistened end of a strip of tumeric
paper in the vapors near the mouth of the test tube.
Much boracic acid will begin to color the tip of the
paper red very quickly, and a little only after boil-
ing down awhile. Muriatic acid, in the absence of
borates, finally produces a dirty grayish brown color.
Now, if the paper is dipped and agitated in a little
water to which a few drops of ammonia have been
added, the paper, where effected by the vapors, will
turn purple to deep blue, according to the amount of
boracic acid present. The contrast with the red
color produced by ammonia on the unaffected parts is
very marked. Wade & Wade.

The Cost of Testing a Mine.
Several inquiries have been received from eastern
persons regarding the probable cost of the examina-
tion of mining properties, and leading brokers report
that they are constantly in receipt of letters, asking
for information on this matter. In many of these
cases the writers exhibit a remarkable ignorance of
what is required of a mining engineer in the examina-
tion of a mine. One broker was asked to employ a
competent man at an expense of not to exceed $50 to
examine a placer mine in the western part of
Routt county containing nearly 2000 acres. As travel-
ing expenses would amount to more than twice that
sum, no one has yet been found willing to go, and in
an examination of a placer property recently con-
cluded, an expert was on the ground nearly six weeks
in arriving at an approximate conclusion regarding
the value of a tract of 2500 acres.
The expense of examining a mine or prospect
varies greatly, important factors being the character
of the property, the character and extent of the ore
body, the amount of development, the distance to be
traveled, the modes of conveyance and the eminence
of the engineer ; for prospects with trifling develop-
ment the charges of engineers are comparatively
light, but for mines which have large bodies of ore
exposed an examination frequently runs up into
thousands of dollars, as besides the fee of the engineer,
numerous assays must be made, assistants are re-
quired to aid the engineer, and frequently many tons
of ore must be run through a testing plant to deter-
mine the best methods of treatment. Less than two
years ago the examination of a large mine in this
State involved the making of 1100 assays at a cost of
more than $1500, and the treatment of 500 tons of
ore. In addition to these expenses must be taken into
account traveling expenses, hotel bills and incidentals,
such as the purchase of necessary tools, the employ-
ment of extra labor, etc.
Average engineers expect to receive as fees not less
than $25 a day and expenses. This is not extrava-
gant, as few even at that figure make more than an
ordinary professional income during the year, while
many are fortunate if they net the average wage of a
bookkeeper. Engineers of established reputation
make much higher charges. There are several en-
gineers in this State who will not look at a mine for
less than $1000, and many instances can be cited in
which the engineer's fee, exclusive of expenses, was
as high as $3000. This class of expert engineer, as a
rule, declines to examine anything but developed
mines, or make general reports covering large areas
of mineral territory, which include geological and
topographical features, water supply, engineering
possibilities and matters of that kind, which require
exceptional skill and experience. On the other hand,
there are in this city not fewer than 100 good en-
gineers who will make examinations of small mines
and prospects for $100 to $500 and expenses, depend-
ent upon the distance from Denver and other factors
mentioned. Large mining syndicates usually employ
their engineers by the year and pay large salaries.
Several Denver men receive $10,000 a year with the
privilege of making outside examinations, and one
Colorado man in the employ of a London syndicate re-
ceives an annual income of about $50,00(l"as consult-
ing engineer for several companies. To make the
trip to Routt county, mentioned above, would rei
$1000 for a competent engineer, ¥2011 for traveling
expenses, $125 for hotel bills, and the wages of two
men at (2.50 to $3 a day for six weeks. The engineer
could probably be secured for 125 a day, and l>v in-
creasing the force of laborers so as to cover' the
ground more rapidly, the total expense would be ma-
terially reduced, but in that case it might be neces-
sary to employ an assistant to the engineer to enable
him to keep his record of extraction up to the work
of the men digging the pits.— Denver, Colo., Republi-

Jasper K- Rand.
J. R. Rand died at Montclair, N. J., July 18th. He
was born September 17, 1837, in Westfield, Mass.
His earliest business connection was with his father,
who was a manufacturer of whips, when Westfield
was the headquarters of that industry. In 1865 his
father retired from business, and Mr. Rand and his
younger brother, Mr. Addison C. Rand, succeeded
him. In 1870 he removed to New York and was for
a time associated with another brother, Mr. Albert
T. Rand, president of the Laflin & Rand Powder
Company. In 1872 Mr. Addison C. Rand began the
manufacture of the Rand rock drills and other
mining machinery, and the two brothers subsequently
organized the Rand Drill Company, with Mr. A. C.
Rand as president and Mr. J. R. Rand as treasurer,
which arrangement continued until the death of Mr.
A. C. Rand in March, which left the chief office va-
cant, when Mr. J. R. Rand was elected to the posi-
tion. He leaves a widow, a daughter and a son, the
latter now representing the Rand Drill Company in
Paris.
California Debris Commission Report.
The annual report of the California Debris Commis-
sion has been submitted to General John M. Wilson,
chief of engineers, and has been made public by him.
It is shown that the amount of money expended in
this work during the past fiscal year was $12,591.
The commission has, since it organized, received 474
applications to mine. Three hundred and sixty-seven
permits have been granted. Thirty-seven permits
have at different times been temporarily suspended,
generally on account of neglect to comply with in-
structions concerning the impounding works or on
account of accident to those works. One hundred
and forty-five permits have been revoked since the
organization of the commission, in most cases because
the mines have been worked out or abandoned or
changed hands.
The commission has been informed by the proprie-
tors of three mines working under permits that their
operations were stopped during the year by injunc-
tions issued by the court of Sutter county. When
the first case of this kind occurred the commission
requested instructions as to its duty in the premises,
and the attorney-general held that as there appeared
to be no question raised as to the validity of the per-
mit issued by the commission it was not expedient
for the commission or any department of the Govern-
ment to intervene in the suit. Accordingly the com-
mission has taken no action in these cases.
The report states that the total amount mined
under permits during the year is estimated at
1,500,000 cubic yards.
No plans for the improvement of the San Joaquin
river have been made by the commission for the
reasons that this stream is but slightly affected by

under the charge of the engineer officer
in whose district it is located. A
former report to Congress by the com-
mission relative to its investigations
as to sites for restraining dams or
works in the Yuba river is briefly
referred to. These proposed plans for
the improvement of this stream con-
template the construction of various
works. It is estimated that the total
cost will be $800,000. There is now
available $500,000 for this purpose.
The fact that the amount thus available
is not equal to the estimated cost of
the proposed works has caused some
uncertainty as to the possibility of be-
ginning work until further appropria-
tions are made. Full illustrated de-
scription of this work was given in the
issue of June 23, 1900.

but the evaporation is great, and only a
small percentage reaches Angels.
Near Angels the Ghost mine is un-
watered and the shaft clear to a depth of
1000 feet. Wm. Bravin has charge.
The assessment on the Utica G. M. Co.
of $501,625 has been reduced to $434, 125.

acres, has been leased for oil by the North-
ern Con. Co., who have erected a 75-foot
derrick. The hole will be started with
11-inch casing and will be sunk 2000 feet.
The Santa Barbara Herald asks that
this shall be believed: "The people of
the Oxnard Oil Co. at Summerland had
an oil well completed for the pump last
December. Up to a month ago it pumped
well. At that time it was sand pumped,
but when there was an attempt made to
pump again it was found that the well
had commenced to flow, and that the pro-
duction by the natural method was
greater than by the pump. The oil does
not run out of the casing in a steady
stream, but comes in jerks, just like the
flows of a pumped well. The tide of the
oil ebbs and flows with the same rhythm as
the tides of the pumped wells near by."

TELLER COUNTY.
(Special Correspondence). — A reorgani-
zation of the Anaconda M. Co. was ef-
fected on July 25th, at a meeting of stock-
holders in Denver, at which 300 stockhold-
ers were either present in person or repre-
sented by proxy, representing 756,503
of the 1,000,000 shares. The company is
organized under a new charter, with a
stock issue of 2,000,000 shares of the par
value of $1 each, the new corporate name
being the Anaconda Con. M. Co., which
takes over the property and assets of the
old company, paying the indebtedness of
the latter, amounting to $125,000. The
stockholders of the old company are paid
for their stock, share for share, in stock
of the new concern. A. J. Zang was made
president; J. T. Milliken, vice-president;
F. J. Campbell, secretary and general
manager; A. E. Carlton, treasurer; all of

Cripple Creek, July 27.
(Special Correspondence). — The inaug-
uration of proceedings on the part of the
general Government to set aside a patent
issued to the Independence Town & M.
Co. for mineral grounds at Independence,
Cripple Creek district, previously men-
tioned in these columns, was the out-
growth of charges of fraud preferred by
the Wilson Creek Co. in its contest for the
grounds in question. In the absence of
any reports of progress by the Govern-
ment in prosecuting the case for cancella-
tion of patent, there are extant what ap-
pears to be authentic announcement of a
consolidation of the Independence and
Wilson Creek companies, who have fought
each other so bitterly for seven years; or
that the Wilson Creek management has
purchased the control of the Independence.
Just what will be done as to the charges
of fraud, on which the Attorney General
of the United States bases the suit for can-
cellation of patent, has not been explained.
The property is among the most valuable
in the district, and it is not to be ques-
tioned that it will soon be operated by
somebody.

by F. M. Woods of the Woods Investment
Co., acting for the Magnolia and New
Zealand G. M. companies. It is surmised
that Mr. Baldwin was acting for W. S.
Stratton, who owns an extensive area of
ground in that locality. The effect of the
sale is to dispose of litigation involving
some of the groups.

Victor, July 28.
The company organized by W. S.
Stratton to operate his various Cripple
Creek properties, acquired by him during
the past nine months, is styled the Crip-
ple Creek Mining & Development Co.,
capital $10,000,000, incorporated under the
laws of Wyoming, W. S. Stratton, W. A.
Ramsay, W. A. Baldwin, J. H. Emerson
and D. H. Rice directors for the first
year. Tho purpose of the company is to
mine and operate in the Cripple Creek
district.
Supt Camp of tho Klkton Con. Co. is
putting in new engine, boiler, compressor,
a hoist, steel gallows-frame, large engine
house, pump, etc. The engine will be
20x48, with 12-foot double reels, carrying
2000 feet of cable. The gallows-frame will
be the second one in the district built of
steel, the Hull City people having tho
other, and will bo 55 feot high to the
sheave. The pump has a rapacity of 1000
gallons a minute; a straight lift of 800 feet
is being installed. Tho output is about
1000 tons a month.
F. M. Woods, acting for the New Zea-
land G. M. Co. and the Magnolia G. M.
Co., has sold to W. A. Baldwin, trustee
for W. S. Stratton. the O. K. and New
Zealand lodes and portions of the Favorite,
Mollie Maguire, Zenobia and Hidden
Treasure claims for $225,000.
The Buck horn O. M. Co. has sold the
Whip-poor-will claim of 2J acres to E. S.
Johnson for $15,000. A "bond and lease
had been given by former officers of the
company for $20,000. It had nearly two
years to run. The company thought it
better to take the $15,000 cash offer than
to wait.
It is locally said that a compromise has
been effected between the Wilson Creek
Co. and the Independence T. & M. Co.
Stratton's Independence is now reported
to have disclosed the existence of flat veins
between the third and fourth levels, run-
ning across the vertical veins; from 3 to 4
feet of the matter is being shipped. It is
said to run five ounces gold per ton. For
the week ending July 19th there were
shipped from the mine 210 tons of ore,
gross value $85,625.
The Anaconda G. M. Co. will reorganize
with a capital stock of 2,000,000 shares,
the new company to take over the prop-
erty and all the holdings of the old com-
pany, the stockholders of the old receive
share of the new for share of the old,
the debt of $125,000 to be paid by those in-
terested in the reorganization. The plan
for the development of the property has
not as yet been fully decided upon. It is
the intention to sink a 600-foot shaft and
lease all the ground to a depth of 200 feet.
The Independence T. & M. Co. and the
Wilson Creek Con. M. & M. Co. have con-
solidated, and the suit which has been au-
thorized by the Secretary of the Interior
to annul the patent issued to the Inde-
pendence Co. will be called off. The Wil-
son Creek Co. was the complainant.

Near Hailey there is an effort to reopen
some of the old silver-lead mines, such as
the Minnie Moore.
In the Hailey gold belt the ore is a cop-
per sulphide. The deepest workings are
at the Tiptop and the Croesus, about 400
feet. The former proposes to sink the
shaft to a depth of 1000 feet. The Tiptop
has a 20-stamp mill, the Croesus a 10-

hours. He uses the gravity system and
says he saves 80% of the values before the
gold gets to the burlaps. He has a liquid
preparation that he has patented, through
which the remaining 20%, together with
the black sand, passes over a burlap
table 60 inches wide, with about 2 inches
of water, to another table 1200 inches in

On the 1st inst. the Montana M. Co.,
limited, closed down the Drumlummon
mine at Marysville. The 110 stamps of the
company's mills have been hung up and
there is no ore in the bins. Fifty men will
be employed for some time prospecting
the mine, and if they uncover new ore
bodies operations will be again resumed.
There is every indication that the shut-
down will be a long one. The Drum-
lummon was a famous gold mine in Mon-
tana. It was located in 1879 by T. Cruse
of Helena, now a millionaire, but then so
poor he could not get credit for a sack of
flour. He sold his mine to English men
for $1,000,000. The mine has since earned
many millions for its owners. It once em-
ployed 700 men.

Belleville, Ont., writes: "An inquiry has
been received for properties containing
iron pyrites or mundic located near rail-
way shipping facilities, from the Mines
Contract & Investigating Co., Toronto.
Pyrites are used for the manufacture of
sulphurous dioxide gas, used extensively
in bleaching wood pulp and paper, also
for manufacture of sulphuric acid. In this
connection it is worthy of note that sev-
eral attempts have been made to ship iron
pyrites from deposits in eastern Ontario,
but the excessive freight rates consumed
all profits. The Laurentian Pulp Co. of
Three Rivers, Quebec, making wood pulp
and paper by the sulphite process, advises

The mines of Aeiiitapileii, ealleil Kl Mez-
quite, Trinidad, Catarina, Buonavista and
Todos Santos, were worked with success
by the old Spaniards and later by miners
from Guadalajara. One of those mines,
the Valenciana, is being developed by an
American company. A 3-stamp mill, a
crusher and a concentrator will be soon in
place. Fifty men are employed at Aeuita-
pilco. The high-grade ore is being sent to
the reduction works of Lonergan & Stan-
hope, and the low-grade ore is being re-
duced by old patio process with success, as
good returns in gold and silver are being
received by the company. J. S. Ickis is
manager. Ten tons daily is the present
extraction; the formation of the district is
quartzite and porphyry.
The owners havo lately acquired rights
on two waterfalls which operate the six
old tahonas used in the reduction of the
ores. The Valenciana Co. will soon erect
a reduction plant.
The San Bartolo mines are southeast of
the city of Topic, 15 miles distant and 60
kilometers from the San Bias seaport on
the Pacific coast. The average of the ore
is 30 ozs. silver to the ton of 2000 lbs. and
1 oz. gold.
On the south of San Bartolo are the
mines of Guadalupe and San Juan ; the
former has a streak averaging 300 ozs. sil-
ver per ton and 3 ozs. gold. The San Juan
has ore of low grade gold and silver. The
present owners have ten men at work.

Dawson reports conglomerate discovered
on Indian river. D. McKinnon claims to
have discovered a "reef" on McKinnon
creek, opposite the mouth of Quartz
creek, from 400 to 500 feet wide, and he
" thinks the space between two reefs,
about 3 miles, is a solid bed of conglomer-
ate, carrying gold." He argues that "the
reef is low-grade free milling, and can be
handled like that at the Treadwell mine,
simply by quarrying out the face of the
cliff."

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co. 's SCIEN-
TIFIC Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Electric Heater.— No. 654,320. July
24, 1900. R. R. Morrison, San Francisco,
Cal. The object of this invention is to
provide a means for annealing gold for
dental uses, for heating water, for steriliz-
ing surgical or dental instruments, for
heating wax composition of rubber and
the like, or other heating instruments for
the preparation and convenient applica-
tion of antiseptic dressings and similar
purposes where the heater can be used.
It comprises an open central stand or sup-
port with a shallow pan within the open-
ing, and ribs by which the pan is sus-
pended out of direct contact with the
stand. A second pan fits within the first
named one, with means interposed be-
tween the two for electrically heating
them and means for controlling the elec-
trical current. An annular disk lies upon
the bottom of the pan with a flanged open-
ing, which exposes a part of the bottom
and forms a restricted operating surface;

means are also provided for controlling
the electrical current:
Automatic Switch. —No. 654,327.
July 24, 1900. T. S. Savage, Oakland,
Cal. The object of this invention is to
provide a means by which the motorman
or other operator upon a car or like travel-
ing vehicle can determine the direction in
which the car should travel upon arriving
at a switch where two tracks diverge from
each other. At the point where the main
and branch line of the track separates is a
spring-pressed switch point normally
closed to cause the cars to move upon one
line of track. A rock shaft and arms car-
ried thereby are provided, one of which
connects with the switch point and the
other with a pressure plate which pro-
jects into the path of the car wheels so as
to be depressed by the weight of the pass-
ing wheels and throw the switch point
away from its contact with the track. A
spring acts to return this switch point
after the wheels have passed the pressure
plate. By means of a foot pedal upon the
car, the plates are depressed so as to pass
inside the switch point after it has been
moved away from its contact and to thus
retain it in such position while the car
wheels pass upon the other line of track.
Wagon Dumping Gears. — No. 654,333.
July 24, 1900. P. Vasquez, Half Moon
Bay, Cal. The object of this invention is
to provide a mechanism for moving the
containing box or body of a wagon or
similar vehicle in a longitudinal direction
and tilting the same to discharge the load
carried thereby. It comprises a rock bar
or equivalent device carried upon a wagon
body, a pinion mounted upon a journal
shaft and having teeth engaging the rack
and means for rotating the pinion so that
by its engagement with the rack it will
draw the latter and the wagon body rear-
wardly upon the bed until it arrives at a
point where it will tilt and discharge its
load. In conjunction with this are stops
which engage with the shaft or roller and
form a bearing about which the box tilts,
and which prevent its sliding farther to
the rear. Rollers are journaled upon the
bed to form an anti-frictional support,
upon which the box travels easily when it
is moved forward or backward.
Apparatus for Working Ores of
Valuable Metals. — No. 654,315. July
24, 1900. T. E. Leece, Bishop, Cal. This
invention relates to an apparatus which is
designed for working the ores of valuable
metals, and is especially useful for sepa-
rating slimes from solutions in which they
may occur, and also for separating heavier
and lighter parts under any condition in
which they may be found associated. It
consists essentially of a tank having one
side at a considerable inclination, and
within this tank is an endless traveling
belt with directing rollers so that one por-
tion of the belt is caused to travel through
the tank in close proximity with the bot-
tom, and the other part is guided back
exterior to the tank by similar rollers.
The material is delivered into the deeper
portion of the tank and the heavier part
settles down upon the belt, which continu-
ally travels up the incline to a point of
discharge exterior to the tank. Trans-
verse partitions having flexible sweeping
lower edges in contact with the inclined
portion of the belt keep the slimes upon
and in close proximity with the belt as
they travel upward. A suitable discharge
chute receives the material, and the belt
is cleaned by water jets and by a revolv-
ing brush before returning beneath the
tank to again enter it.

The Johnston Pipe Wrench.
Wm. B. Volger, 88 Chambers St.,
N. Y. : The large automatic pipe wrench
which you sent me January last has been in
almost daily use, is as good to-day as when
we received it, and is the best tool for the
purpose that we have. It is very essential
that all the joints made up be absolutely
tight, and this wrench has been used in
making up over 500 joints, consisting of
extra heavy pipe and extra heavy fitting,
and not one of these joints has ever leaked.
We attribute this success very largely
to the wrench, which grips the pipe in
such a way that we have never hesitated
in putting the greatest strain upon it,
without any fear of crushing the pipe.
I made personally over half of these
joints myself with this wrench, and say
unhesitatingly that it is the best tool of its
kind that I have ever seen.

This tool is intended for use in different
mining sections, giving general satisfac-
tion.

Brown's Electro-Geodetic Mineral Finder.
An Electrical Geodetic Apparatus.
Among other new things in the mining
and scientific world is what is styled an
"electric survey." Men have always
claimed ability to tell where mineral is lo-
cated, by surface indications, and it is not
strange that, with the new order of
things, the old divining rods and "dousing
sticks " should be discarded and electricity
brought into the effort to indicate the lo-
cation and course of mineral veins. P. H.
Brown of Los Angeles, Cal., has a pat-
ented device that he styles an "electro-
geodetic mineral finder." He furnishes
the following explanation of its operation :
"The instrument used is a modification
of the common form of the Wheatstone
bridge, the modifications rendering the in-
strument capable of overcoming the inac-
curacies of measurement heretofore caused
by earth currents and abnormal resist-
ances set up by electrolysis when battery
currents are sent into the earth from a
metallic electrode. In using the machine
the custom is to make many measure-
ments of the resistances of the same defi-
nite length of earth in a given locality. If
there are no ore bodies within one-half of
the distance between the electrodes from
the surface of the earth, the current will
find the path of least resistance in the
moist earth nearest below the crust and
close its circuit through that path. Under
this condition, all the resistances in the lo-
cality will approximate the same. In tak-
ing these different measurements, how-
ever, should we measure the resistance of
a certain definite length of earth under-
neath which lay a body of ore, less than
one-half the distance between the elec-
trodes, from the surface, then the current
would find the path of least resistance, in
passing down vertically to the ore body to
a point nearest the positive electrode or
rod, would pass laterally through the ore
body to a point nearest the other rod or
electrode, then vertically upwards to the
other electrode.
" The lateral resistance through the ore
body would show comparatively no re-
sistance and the reading on the instru-
ment would be only one-half to nine-tenths
of the amount indicated on the instrument
by the other definite lengths under which
there was no ore.
" To tell the depth of the ore body from
the surface it is only necessary to vary the
length of earth measurements, as for ex-
ample : If a body of ore was 100 feet be-
neath the surface, 100-foot measurements
over this ore would not indicate its pres-
ence, for the reason that the current
would have to go down 100 feet to the ore,
pass laterally through it and up through
another 100 feet of earth resistance, thus
passing through two vertical earth re-
sistances of 100 feet each, aggregating 200
feet of earth resistance as against only 100
feet on the surface, in which case the path
of least resistance would be near the sur-
face. In order to indicate the presence of
this ore body 100 feet beneath the surface
it would be only necessary to take surveys
of a little over twice the depth, say 220
feet. In this condition the two vertical
resistances of the earth, aggregating 200
feet, would be less than the surface re-
sistance of 220 feet, and the current, seek-
ing the path of least resistance, would go
down to the ore, pass laterally through it
and go vertically up to the other rod; and
to locate it, it would be only necessary to
take several parallel or radial measure-
ments of the same definite length. A
measurement taken over the ore vein or
body would be low. The other measure-
ments taken of the same definite length,
for comparison, being removed from and
not over the ore body, would be higher,
and it is only necessary to shorten up the
length of earth measured to arrive at a
point where the current will leave the ore
body and pass through the crust to ap-
proximate the depth. The variations of
the instrument, being very marked, will
show the depth.
" For a further description of this pro-
cess I refer to patent No. 645,910, March
20, 1900."
The illustration gives an idea of how
the apparatus looks in readiness to oper-
ate. Its inventor claims that it is "thor-
oughly scientific," and that he can locate
gold and other metals by its use.

Pittsburg reports : Tho usual slump in
the price of iron and steel, which comes
along every August, is on, and buyers are
waiting for rock bottom to be roached be-
fore placing their orders. Dealers say
that this has already been touched, and,
in fact, one prominent firm has refused
several orders at current prices, although
this only applies to steel wire.
There is one branch of the trade which
is a most uncertain quantity, and that is
tool steel. Thirteen of the principal tool
steel companies in the country have
formed a combination under the title of
the Crucible Steel Company of America.
As they represent about 95% of the total
output, they may conclude to stiffen the
price of tool steel, the price of which has
only been raised once in fifteen years. But
as there is a keen competition between the
tool steel of this country and that of for-
eign manufacture, that fact may act as a
brake on any advance.
The Pittsburg Commercial gives the
following details of the disagreement ex-
isting between the Bessemer Pig Iron
Association and the Steel & Wire Co.:
"The Steel & Wire Co. some months ago
contracted with the Bessemer Association
for the dolivory of 50,000 tons of Bessemer
iron at an average of $25 a ton, deliveries
to run until August. Of this tonnage
30,000 tons have been shipped, but 20,000
tons have not been taken from the fur-
nace men, and the Wire Co. has declined
to name a place where the iron may be
delivered. The furnace owners claim that
the action of the Steel & Wire Co. is due
to the decline of $7 a ton in Bessemer pig, I
but that they propose to hold the Steel & |
Wire Co. to its contract."
The Bessemer Association has about
75,000 tons of pig iron on its books con-
tracted for at from $22.50 to $24 per ton,
and in many cases the buyers are trying
to get rid of taking the goods. Some of
the furnace owners say that the contracts
will go into court; others believe that an
amicable settlement will be made.

metals, both gold and silver. Samples of ore tested free of
charge. Several mills saving over 90 per cent of values by
bullion returns. Simplicity. Economy. Efficiency.

THE IMPROVED BARTLETT CONCENTRATING TABLE.
The BARTLETT CONCENTRATING TABLE has been GREATLY IMPROVED recently by the substitution of iron
in place of wood wherever possible. It is now built with SOLID IRON TOP, PLANED TO A TRUE SURFACE AND
POLISHED ; all parts are made by template and EACH PART BEING INTERCHANGEABLE. As now constructed,
the table has no special wearing parts and will last for many years. It has a CAPACITY OP PROM FIFTEEN TO
FORTY-FIVE TONS IN TWENTY-FOUR HOURS, according to the class of ore worked. It is the only table in the
world which will take the place of jigs and do away with all costly and complicated machinery.

# # # " Now about concentrating tables. Here's a fellow
who says there's nothing equal to the Wilfley, and I am trying to
convince him that old man Woodbury over in California makes
the finest table in the world." " No, sir," said his comrade, " you're

THE TREMAIN STEAM STAMP MILL
has made many fortunes for its owners. It costs
but little money. Can be transported anywhere.
A Money Maker in Nicaragua.
MURRA GOLD MINING COMPANY, NICARAGUA, C. A. »
Nicaragua, June 20, 1899. /
GATES IRON WORKS, CHICAGO.— GENTLEMEN:
After an experience covering a period of three years with both the first and improved " Tremain Steam Stamp Mill," in every par-
ticular I have lound it perfection— a money maker, and just the thing for a small capital, while companies organized on a large scale
would do well to look into its merits.
I find no difficulty in orushing eight tons of ore per day and running on hard ore. This mill should be a winner.
Very truly yours,
[SIGNED] L. W. ADAMS,
General Manager Murra Gold Mining Co.

December 23, 1899.
i2 has not cost us $1 for repairs, and to-day is
Our Tremain Mill is giving us good results, and although being in operation since
making 180 drops per minute with 95 lbs. steam pressure.
The ore we are working at present Is soft and we mill in 24 hours, using No. 10 slot screen, 15 tons.
Yours truly,

Running Under Compressed Air in West Australia.
293 ST. GEORGE'S TERRACE, PERTH, W. A., February 6, 1900.
P. R. PERROT, ESQ , Agent of Gates Iron Works, Perth, West Australia.
Dear Sir: In reply to your enquiry as to the working or the Tremain Mill on the Burbanks Grand Junction, I would state
that at the start we worked this from the boiler supplied by the Gates Iron Works Company, but owing to certain irregularities of
the running, which were in a measure due to the intermittent supply of ore and the short time that we were able to run it per
day, I finally laid on air piping from my air compressor, a quarter of a mile distant, aad used the boiler as an air receiver,
with the result that I got an absolutely constant run, which, I believe, averaged about 105 drops per minute, and this was kept up
with great regularity and showed a much better return in the treatment of the ore. The usual air pressure in this case was 8J lbs.,
whereas under steam we were not so satisfied with the result as worked at 100 lbs. By this we were also saved in cost the charges of
stoker, fuel and water, and it was worked with much greater cleanliness, and during the whole time the mill was running— which was
several months— it never froze up on us or Bhowed any signs of trouble in that direction.
The mill is now temporarily stopped, but when it is again started I shail most decidedly continue the use of compressed air.
Yours faithfully,
[SIGNED] GEO. HEWER.

SPADONE'S CONCENTRATOR BELTS.
PATENTED.
This illustration shows the edge flanging out-
wardly as it passes over the pulley. This re-
lieves the strain from the top and bottom of the
edge by directing the strain automatically to
the inside face surface of the edges. Hereto-
fore all belts have been so constructed that
when they pass over the pulleys or rolls, a di-
rect strain comes upon the top or at the base of
of the edges, causing the edges to break away
from the body of the belts in a very short time.
We avoid tfUe Mechanical Defect by our Spadone
Curved Edge. Belts made to fit any machine—
4, 5 and 6 feet wide. Prices and samples on ap-
plication.
AMALQAM PLATE CLEANERS.
Our Amalgam Plate Cleaners are made of Pure Rubber in moulds, thus Insuring a plate cleaner

CROWN GOLD MILLING CO
Manufacturers of the "CROWN" CONCENTRATOR and CROWN
ORE 5IZER. A dry process of sizing and concentrating ore, sand or
gravel. Designed to accord fully with the laws of specific gravity,
and especially adapted to refractory ore or localities where there is
no water.
The chief claims for the Crown Concentrator are that it occupies
less floor space and has nearly four times the capacity of any wet
concentrator; that it will concentrate ores containing base and refrac-
tory metals that ordinarily slime and carry off values; that it effects
a saving of values far above the ordinary methods of concentration.

GATES FINE CRUSHER.
The result of ten years' solid work. Success at last. What
we wanted, and the public demanded, was a Gates Gyratory Rock
and Ore Breaker (always adjustable and indestructible) so modified
in design as to make one-half-inch product from three-inch sizes,
rapidly and cheaply. The H Fine Crusher will do this work. It
takes the place of expensive big rolls and often prepares ore,
without further crushing, fine enough for coarse concentration or
cyaniding. In any event, it is the greatest and best intermediate
machine between the coarse breaker and the pulverizer.

XHE GRIFFIN
THREE ROLLER
yvvi
Tho Griffin Three Roller Ore Mill is a simp.y constructed Mill, suitable for working all kinds of ores that
require uniformly fine crushing by tho wt-t procoss. Thix Mill is a modification of tlm well-known Chilian
Mill, but the rollers run upon a crushing ring or die, which is inclined inwardly at an angle of about 30 degrees,
tlie rollers themselves also being inclined to tho central shaft of the Mill, thus utilizing tho centrifugal force,
as well as the weight of tho rollers thomselvos as a crushing agont. The Griffin Three Roller Ore Mill is there-
fore i -Mill of great strength, and has few wearing parts. Wo construct these Mills with extrome care, using
only the best of raw materials, which are most carefully worked by men who aro specialists as mill builders.
We sell the Griffin Ore Mill on its determined merits, and will gladly supply full information regarding it to
any ono.

Testing Oils.
A good way to test oils is to place
them side by side on blotting paper,
and place this for a short time on the
cylinder chest or on a steam heater.
The oil which penetrates the blotting
paper quickest and spreads widest over
it is always the poorest oil ; the oil
which spreads widest in part and leaves
a defined ring in the center, must be a
compounded oil, as it shows by its light-
ness and quicker disappearance of the
miter ring that it is compounded from
material of a very light gravity. If on
longer exposure to heat, or by giving
it more time, the whole of the oil on the
blotting paper disappears, the sample
must be composed entirely of mineral
oil ; and when an inner ring with a well-
discernible ridge is formed and remains
longer, a proportion of paraffine-hold-
ing stock must have been compounded
with a lighter mineral oil ; and when a
center ring of decided outline and
darker color is formed, and no perma-
nent translucency imparted to the pa-
per, the compound must have been
made of light hydrocarbon oil with an
addition of still residuum stock, how-
ever well defined or bleached.

transmits power 35 miles to the
Mercur mills at 40,000 volts.
Raising transformers are three
in number and are connected in
the star form. Each trans-
former has a capacity of 250
kilowatts. The middle points of
both the high-tension and low-
tension circuits are grounded.
In general design these trans-
formers resemble the transfor-
mers used in the high-tension
tests at Telluride, the design
and construction having been
under the direction of the same
man in both cases. The line ex-
tends from Provo at an elevation
of 4500 feet to Mercur, at 2000
feet above Provo, and the line
reaches an extreme height of
about 10,000 feet above the sea
level. Three miles of the line
are strictly mountain construc-
tion. The lightning protection
is afforded by choke coils and
non-arcing metal arresters.
The insulators are of glass. The
design was based on the tests at
Telluride and they were made
especially for this plant. The
insulators are held on special
pins of oak which are thoroughly
paraffined. The lower part of the
insulator is 5 inches above the
cross-arm.

Concerning the Mining Industry.
In last week's issue mention was made of the com-
mendable character of the practical work being done
by the U. S. Geological Survey and its immediate
value to the miner. It was the intention this week
to go further into the subject. The subsequent re-
ceipt of a monograph by Director Walcott of the
TJ. S. G. S., read before the Washington meeting of
A. I. M. E., on "The Work of the TJ. S. Geological
Survey in Relation to the Mineral Resources of the
U. S.," shows that in that paper the head of the
Survey goes into the discussion, and puts it
about as it was intended to editorially discuss it.
Hence as a subject of great general interest is here-
with given in a condensed form some of what Di-
rector Walcott has to say concerning the connection
of the economic work of his Bureau with the mining
industry.
The general principle upon which the Survey has
been doing its economic mining work is, that it
should endeavor to accomplish for the mining in-
dustry, as a whole, what the individual mining en-
gineer or mine owner cannot succeed by his unaided
exertions in doing ; that it should not undertake to do
what could be done as well, if not better, by indi-
vidual exertion ; that it should not interfere, either
favorably or unfavorably, with the private business
of individuals or corporations, or enter into compe-
tition in their legitimate occupatious with profes-
sional men, such as mining engineers, etc.
If it were more generally understood that such is
a proper limitation of the work of the members of
the Survey, they would not be asked, as " they fre-
quently are, to tell some individual or corporation
whether his or its land contains valuable mineral
deposits, since all the information they are at liberty
to impart with regard to that land is contained in
the published maps and reports, which may be ob-
tained by all. If the individual or corporation is un-
able to deduce from these publications all the com-
mercial data that may be desired, a mining engineer
should be employed for the purpose. An attempt
by the Survey to acquire and communicate such im-
formation respecting any parcel of land would be in
the nature of a report for private parties, which
would be an interference with the business of the
mining engineer and a violation of law. Neither
should the Survey be called upon to assay or analyze
ores for private parties, for that is manifestly inter-
ference with the business of the assayer ; nor should
it be called upon, as it sometimes is, to tell a man
what process, or which of two or more processes, is
best adapted for the treatment of his ores. Even
if the members of the Survey were fitted to pass
judgment upon the relative value of technical pro-
cesses or machines, and should pronounce such judg-
ments, they would naturally be regarded as interfer-
ing unwarrantably with the business of the person
or corporation owning a process or machine which
was not favorably considered in their report. If it
were proper that work of this nature should be done,
it would be impossible to acquire the knowledge
necessary to meet such demands with the amount of
money at present available, or even with ten times
that amount.
In the field of more purely geologic investigation,
the general object has been the determination of
laws which govern the formation of deposits of the
useful minerals, and of the rock formations in which
they are most likely to be found. This object can be
attained only by long and careful study of many and
varied deposits — as far as possible in the condition
in which they were originally formed. Ore deposits
are as a rule the result, not of a single process, but of
many successive concentrations of minerals ; and in
those deposits which are found near the present sur-
face, the effects of the latest of these processes —
weathering or the action of surface waters — are
likely to have obscured all others. In order best
to accomplish the object sought, the first studies
were made of mining districts in which mining devel-
opments have been most extensive, the mines are
deepest, and the most varied forms of ore deposits
have been disclosed.
In the prosecution of these studies, the geologists
often obtain results of immediate value to the miners
and mine owners of the particular district under in-
vestigation, such as the determination of the prob-
able direction which the ore bodies will take in un-
explored ground, the faults which are likely to cut
them off, and other obvious limitatations which geo-
logic conditions may suggest. These results are of-
ten of secondary importance as compared with the
more general deductions, being useful to only a few
persons interested in a limited district, while the
general deductions, if correct, are of benefit to the
whole mining community.
A brief statement of the underlying principles which
govern our choice of fields of work is made,
because that work has been frequently criticised :
the criticsm made by miners being that the Survey
chooses developed districts, where the general facts
with regard to ore deposits are already known,
rather than undeveloped districts, where the predic-
tions might be of more use to those who own mines,
and might actually help in their development. From
a partially developed district we can usually learn
only superficial facts, which are not likely to yield
any contribution to general laws. Whatever may be
said of the probable value of such a district belongs
to the province of the mining engineer rather than
to that of the Government geologist, since it in-
volves such preliminary work as sampling of ores,
prospecting, development, etc., which the geologist
cannot do.
Another criticism has been that more work is
done in one State than in another. But if it be
admitted that the principles mentioned should
govern our work, it is evident that we can-
not be guided by geographic or political considera-
tions, but that we must study ore deposits where
they can be studied to the best advantage. In the
topographic work of the Survey a more or less gen-
eral geographic distribution has been possible, and it
is also desirable, but in geology the Survey must con-
tinue to be the judge of the importance and inter-
dependence of the problems to be solved, and of the
best method of solving them.
A correct geologic map is the first and most
essential basis for the study of a mining district; and
where the deposits are beds in sedimentary strata, as
is the case with coal, and sometimes with iron ore
and other substances, it furnishes practically all that
the mining engineer needs for opening and exploiting
the mines. By the folio publication, however, a new
avenue is opened for disseminating geologic informa-
tion promptly and without waiting for a final and ex-
haustive report. Where important groups of mines
i are concentrated within small areas, special maps of
size to fit the folio are ma e of those areas, on the
largest practicable scale, accompanied by sections
and explanatory texts setting forth in concise terms
the main facts of importance to the miner, and these
are published as special folios; that is, folios that do
not form an integral part of the regular Geologic
Atlas of the United States. In this form there have
already been published folios covering Cripple Creek
and Tenmile districts in Colorado, the Nevada City
in California, and the Butte district in Montana. A
folio of this form often supplements a monographic
report, as it meets the demand of the mine owner for
more prompt issue, and may be produced at smaller
cost than a monograph. On the other hand, it is less
likely to result in scientific deductions of general ap-
plicability, unless it is followed by a monographic re-
port.
It may be anticipated that in the course of time
the incidental areal surveys and studies of special
minerals will gradually supersede those of the small
groups of important mines; but at present we. have
plans made for surveys of a dozen or more mining
districts in the western portion of the United States,
and of several in the central and eastern parts, which,
under the present appropriations, can only be taken
up one at a time and at considerable intervals.
In the line of what may be considered technical
studies, the duties of the Survey toward mining in-
dustry are less easy to define; for in this line there
is more danger of encroaching upon the legitimate
field of the mining engineer or metallurgist. Yet
the same general principle is applicable here; namely,
that the Survey should confine itself to those inves-
tigations which it is better fitted to make than is the
individual. Thus, in our early work on Leadville,
where lead smelting had recently reached a stage of
development hitherto unknown in this country, it was
thought that a scientific discussion of the processes
involved, in the light of the improvements made in
practical methods, would be of advantage to the
smelting community throughout the country. It was
found, however, that so great was the commercial im-
portance of the industry, and so rapid the advance-
ment in metallurgic science, that the delays inherent
in a Government publication greatly impaired, if
they did not altogether nullify its value.
It is evident that the investigation of technical pro-
cesses in their commercial application is not a legiti-
mate function of the Survey. Its employes are ex-
pressly shut out from a commercial use of their
knowledge, and are chosen for their proficiency in
geology rather than in technology. There may arise
cases, however, in which it will appear possible for
them to determine the underlying principles or laws
that should govern some widely applied technical
process, and in which it will seem advisable and pro-
per for them to undertake such investigations.
It seems evident that the collecting of accurate
statistics of the mineral productions of the country,
which form the most important basis of all mining
business, is a prime duty of the Survey. No branch
of statistical science is in greater need of technical
knowledge and thorough system than that which
deals with mineral production, and none is more liable
to be led into error, if the collector's opinions are
in any way biased by his interest. There is no body
of men more absolutely disinterested than the em-
ployes of the Survey, since, under the law, they can
have no commercial interest in the subjects which
they treat. Their field of work is so wide that, by
one or another, a certain personal familiarity with
all the sources of supply of the various mineral pro-
ducts of the country is acquired, which is available
for the guidance of the statistical division.
At the last session of the Fifty-fifth Congress an
amendment was introduced establishing a Division of
Mines and Mining in the Survey. This extended its
sphere of statistical work to gold and silver, and
made a special appropriation for the division. It
also provided means for the more prompt publication
of its reports. Had this amendment passed, it is be-
lieved that the scope of usefulness of the work of the
Survey would have been very materially increased.
All of its various economic branches would then have
been conducted under the supervision of a single
chief, by which means a more uniform and comprehen-
sive system, both of field work and of publication,
might have been inaugurated.

technology, its designation was changed to the
Division of .Mineral Resources. In accordance with
the duties implied by this title, more and more at-
tention has been paid to statements of the geologic
and geographic distribution of our mineral wealth,
whether developed or not; and the immediate future
will see this important work of the Survey expanded.
I'm' more than ten years the Division of Hydrog-
raphy of the Survey has been making measurements
of streams and computations of their daily discharge
at various points. At the same time, it has been in-
vestigating the movements of underground waters
and the causes which give rise to them. The results
have economic importance to the miner in his under-
ground operations, as he must often contend with
water, ami bis ability todispose of it successfully may
govern the question of profits. He often seeks in
flowing water the power for operating, directly
or indirectly, mines, mills, etc. In many sections
the location of reduction works is governed
largely by the question of water supply and its per-
manence through seasons and years. The results of
the investigations of the hydrographers are sought
in considering the erection of plants of this character.
There is also an indirect way in which the question
of water supply affects the feasibility or profits of
mining. Throughout the western third of the United
States, from the Rocky Mountain region westward,
there are great deposits of ore, the value of which
per ton is so small that they cannot be profitably
worked unless many conditions are favorable, such as
cheap foodstuffs and ready transportation, by which
the cost of living and of labor may be reduced. The
region as a whole is arid, and farm and other pro-
ducts, brought from the humid regions, are expen-
sive. By the development of agriculture through
irrigation, and the building up of small producing
communities throughout the semi-arid and arid West,
the cost of living is greatly reduced, and it becomes
practicable to work to advantage mineral deposits
otherwise unprofitable. This dotting of the coun-
try with farms and villages is possible through a
careful conservation of the available waters, such as
can result only from a thorough knowledge of the
natural conditions. This knowledge is being obtained,
through the Division of Hydrography, as rapidly as
the means available will permit.

Much has been already said herein regarding "learn-
ing mining engineering or the science of mining through
correspondence schools." Those schools are not without
merit, and are not to be decried ; doubtless one could
learn to play the piano or run a bank the same way, but
many men will follow the old way of oral instruction, ac-
companied by personal experience.
However interesting from a laboratory standpoint
liquid air may be, there is much exaggeration in the
claims made for ita commercial application, and serious
attention is not to be given to projects " for using it as
an explosive in mining." The slightest accession of heat
occasions so rapid a return to its normal state as to pre-
clude practical possibility of use in that way.
Millmen of experience think that it is rarely neces-
sary that the stamp should weigh over 1000 pounds, and
some look upon that weight as the maximum for effi-
ciency. A lighter stamp with sufficiently higher drop to
insure sufficient momentum is generally preferred. In
this, as in everything else about a stamp mill, the ore is
the thing to be suited. Whatever is best for the ore is
the best to use. And this can only be determined by in-
dividual experiment.
Most of the gold in the old copper plates may be ex-
tracted by heating the plates over a charcoal fire, plac-
ing the lower side of the plate next to the fire, heat to
about boiling point of water, then remove it from the
fire and scrape with a broad chisel. This will remove
most of the gold and silver amalgam, which melt into a
base bar. If the plates are very old and brittle by becom-
ing saturated with quicksilver, the only method is to
melt the entire plate and refine.
Proper foundation is as necessary for a gas engine as
for any other form of power application. In setting a
horizontal gas engine there should be a slight slope longi-
tudinally, downward, from the head end of the cylinder
toward the crank; about £ inch, in the length of the cyl-
inder will suffice, this to cause a flow of the waste oil
toward the open end of the cylinder. Otherwise its ten-
dency is to settle at the head end, and this interferes with
the working of valves and igniter.
In dressing plates when well coated with amalgam it is
the practice of many millmen not to stir clear to the bot-
tom, where it is thickest. Washing with a hose and a
slight stirring of the surface with a whisk broom dipped
in the dressing mixture suffices to remove adhering
dross. Thus a heavier coating of amalgam may be car-
ried, in a manner similar to the usual treatment of a
chuck block. In the final brushing little ■ riffles are
formod ; and if it be done crosswise tho channels fill up
with sulphides. This interferes with the gold coming in
contact with that portion of the plate surface, and it is
therefore thought better to finish lengthwise.
A good belt dressing (liquid) for summer use is
composed of beeswax 4 lbs., pitch 5 lbs., resin 3 lbs ,
noat's-foot oil 13 lbs. Melt the beeswax first and add tho
other ingredients in the order named. For winter use
the neat's-foot oil should be increased to 15 lbs. If a
solid dressing is required, for summer use— beoswux 8
lbs., pitch 51 lbs., resin 7 lbs., neat's-foot oil, 1 lb.; for
winter use make the resin 6A lbs. The fluid dressing is
the best, but more wasteful; the solid is more eco-
nomical.
To note so small a quantity as .025 ounco gold to tho
ton of ore, place four ounces of finely pulverized ore in a
bottle, add an equal volume of tincture of iodine and agi-
tate the mixture for at least an hour, letting it occasion-
ally settle. There should then bo introduced into the
clear solution a strip of Swedish filter paper and dried;
the introduction of the strip and subsequent drying
should be repeated six times, to saturate the paper
thoroughly. Upon burning the strip, the ashes, in caso
gold is present, will show a purple coloration which will
quickly disappear upon pouring bromine water over it,
if geld be present — an indication of its presonce.

Carbons for electric arc lights are made from a coke
which is a by-product of the process of petroleum refin-
ing, being the solid residuum left in the refining stills
after the oils have been driven off. This material is cal-
cined to drive off volatile matter, then ground and bolted
to free it from coarse particles. In this condition it is
almost pure carbon, and before being molded it is mixed
with a binding material. Two processes are in use for
molding the carbons. In the first they are molded under
hydraulic pressure in split molds, eighteen or twenty
carbons being molded at once. In the second method the
material is forced through dies by means of heavy
hydraulic presses, the carbons being molded in 4 or 5-
foot lengths and afterward cut to the required size. They
are then baked in kilns for eight or ten days, and after-
ward sorted and tested. In some cases the carbons are
plated with copper by means of special machines.
Acetylene is one of those bodies the formation of
which is attended with the disappearance of heat, and
for this reason termed an endothermic compound, in
contradistinction to those bodies which evolve heat in
their formation, which are called exothermic. Such en-
dothermic bodies are nearly always found to show con-
siderable violence in their decomposition, as the heat of
formation stored up within them is then liberated as sen-
sible heat, and it is undoubtedly this property of acety-
lene gas which leads to its easy detonation by either heat
or a shock from an explosion of fulminating mercury
when in contact with it while under pressure. If acety-
lene be heated in contact with air to a temperature of
480° C. it ignites and burns with a flame, the appearance
of which varies with the way in which the acetylene is
brought in contact with the air. With the gas in access,
a heavy lurid flame, ■ emitting dense volumes of smoke,
results, while if the gas be driven out in a sufficiently
thin sheet it burns with a flame of intense brilliancy and
almost perfect whiteness.
Cyanide solution from a leaching tank contains
free cyanide, caustic potash, gold potassium cyanide, sil-
ver potassium cyanide, and compounds of the baser
metals. The gold and silver are precipitated from the
solution by means of zinc shavings (and at Mercur, Utah,
by zinc dust) as a blackish powder on the zinc. The zinc
itself goes into the solution. During the process hydro-
gen gas is evolved. From five ounces to one pound of
zinc is required for every ounce of gold recovered. In
cleaning up the zinc box, the blackened, undecomposed
shavings of the first box are transferred to an iron pan,
the gold slime remaining on top of the screen is stirred
to make it pass through, after which the screen is re-
moved and washed. The cock at the bottom of the com-
partment is opened, and the slime settled there is drawn
off in a bucket, where it again settles, after which the
clear cyanide is decanted and returned to the zinc box.
The collected slime is put on a filter, drained of cyanide,
and washed with water. The slime consists of metallic
gold, silver and copper precipitated from the cyanide.
In refining the precipitates, they are placed in a cast iron
pan, subjected to a dull red heat in a muffle furnace.
Clean slime appears like a fine black mud. When the
roast is complete the precipitate is treated with hydro-
chloric acid in pans having mechanical agitators. The
residue is washed and dried in filters, fluxed and replaced
in the roasting pan for drying, afterwards smelted into a
bar and sent to the mint or U. S. assay office.

The Empire Mines, Past and Present.
NUMBER II.
Written tor the Mining and Scientific Press by
George W. Starr. Resident Manager.
In 1878 the Empire Mining Co. was controlled by the
estate of W. B. Bourn, the managers of which, after
having the mine examined by three well known ex-
perts, concluded that it was worked out and too deep
for profitable working, and were about to abandon
the property when W. B. Bourn, Jr., returning from
Europe, after an extended visit to Grass Valley de-
cided to take over the management and formed a
new company, called the Original Empire, which
acquired all the assets of the old Empire Co. The
shareholders of the Empire were invited to join, all
declining except the late J. B. Fargo, who accepted,
and his estate retains to-day the interest acquired
by him in 1856. The reconstructed company took
possession in 1879, shortly afterwards commencing
of the North Star to J. D. Hague and associates of
New York, and in 1888, with an idea of retiring from
mining, Mr. Bourn sold the control of the Empire
and retired from active management.
My connection with the Empire commenced in
December, 1881, succeeding to the superintendency
on the resignation of V. M. Clement in 1887. In
1893, accepting a call to South Africa, I tendered my
resignation, after expressing my faith in the prop-
erty to the management with the hope that discour-
agement would not follow the splitting up of the
Ophir ledge into several leaders at the 1700 level.
(See lower engraving, front page, of split Ophir
ledge.) Some exploitation work was carried on dur-
ing the years 1892-93-94-95, but the mine did not pay
expenses, and in 1896 the interest sold by Mr. Bourn
was repurchased by him.
Shaft sinking was then resumed and the 1800, 2000
and 2100-foot drives or levels extended. In 1898, re-
turning from South Africa, the management of the
property being tendered me was accepted, after I had
made a thorough examination and had prevailed upon
the executive committee to adopt fixed plans and
policies laid down in the report I submitted to them.

pumping operations and soon resuming shaft sinking.
Operations were conducted under the greatest diffi-
culties, financial and otherwise, for this was a period
when belief in California quartz mining was at its
lowest ebb. Faith and energy triumphed, and in
1883 the old Empire entered a new era of prosperity.
In 1884 water power was introduced at a cost of
$100,000, the plant reconstructed and improved, and
in 1886 the 20-stamp mill was increased to forty
stamps.
It was the successful reopening of the Empire that
inspired Mr. Bourn to purchase and reopen the
North Star, one of the oldest properties in Grass
Valley, and from the early '50s to 1870 a very large
producer. In 1884 Mr. Bourn purchased the prop-
erty from W. E. Dean, Thos. Bell, J. A. Faull and
others for $16,000, formed a company with a working
capital of $40,000, which, with an assessment of
$20,000, and the profit of the mine, sufficed to thor-
oughly reopen and equip the property with what was
in 1886 the model plant in California. The successful
reopening of the Empire, followed by the wonderful
results at the North Star, gave Grass Valley quartz
mining an impetus that was felt throughout the State.
In 1887 Mr. Bourn and associates sold the control
The essence of this report is, in my opinion, appli-
cable to gold mining generally in California. I found
that by extending the drives my former theory of
the split in the Ophir vein had been proved true, and
that as soon as the large "horse" had been driven
through the vein was as strong and true as ever.
The 2100 north drive I found had penetrated a rich
ore body which then had cut 540 feet of good ore.
Good ore was in the face of the drive and the ground
above was virgin to the surface, this drive being far-
ther to the north than any of the old levels. Very
large areas of north and south ground were unex-
plored. A probable valuable reserve was in a par-
allel vein known as the Rich Hill (which had not been
worked since 1880), in other parallel veins and in
extralateral rights. Lack of sufficient development
was the chief cause of all underground troubles. The
surface conditions were deplorable, the mine having
outgrown the plant. As a condition of acceptance I
asked for a fund of $200,000 to properly equip and
open up the property, explaining that, while the pro-
posed outlay would require that amount, it was
probable that the actual outlay might be less if the
old hoist and pumping plant would live long enough
to allow mining and milling to continue. The execu-
tive committee did not think the ore in sight would
justify such an expenditure. My answer to this was
that I would admit no large quantity of ore was in
sight, but that they controlled a property with a
record of forty-seven years' continuous working, with
a very limited area of its holdings exploited, a pro-
duction of more than $7,000,000, with but a small per-
centage profit, the chief cause being lack of develop-
ment and a plant not suited for economical or expe-
ditious working under existing or future conditions,
and that, in my opinion, the mine justified the ex-
penditure. This letter soon followed :
San Francisco, May 9, 1898.
Geo. W. Starr, Esq., The Empire Mines, Grass Valley
— Dear Sir : I have the pleasure to inform you that
the executive committee have accepted your ideas and
that you were this day appointed managing director by
the board of directors. You will be given a free hand in
the equipment and development of our property, with
the understanding that if necessary to carry out your
plans the sum of $200,000 will be furnished you, and that
on the completion of the plant the necessary expendi-
ture for 600 feet per month of development, consisting of
shaft sinking and drives, will be allowed.
We sincerely trust that, including the cost of the
above development, you will succeed in bringing all costs
down to $7 per ton. Yours very truly,
(Signed) W. B. BOURN, President.
With the responsibility thus resting upon me, I
concluded to first try and force underground develop-
ment, with a result that far exceeded my expecta-
tions. The 2100 drive was rushed ahead and con-
tinued in good ore; the total length of this ore body
along that level has since been found to be 1740 feet,
raises above the 2000 level showed most encouraging
results; shaft sinking was continued under difficulties.
In the meanwhile plans and estimates were under
way for a new plant and on July 6, 1898, the work
of pulling down and reconstructing was commenced.
All immediately necessary working parts were com-
pleted on January 7, 1899. It is interesting to
note that this re-creation was accomplished without
hanging up more than ten stamps at a time, and the
change from the tracks of the old incline and hoist to
the tracks of the new thirty-pound rails in shaft and
on headgear was made in forty-two hours, during
which time forty stamps were dropping. I had no
occasion to call upon the company for expenditures,
but had the pleasure of producing sufficient to not
only pay for all improvements, but to give the share-
holders a dividend.

Some Facts About Para Rubber.
It is reported that a new rubber producing area
in the Amazon section, South America, recently dis-
covered and as yet untouched, is larger than that
now being worked. The State of Para produces
about two- thirds of the rubber shipped from the port
of that name, the remainder coming from the States
of Amazonas, Peru and Bolivia.
The rubber tree in appearance resembles the Eng-
lish ash. It grows to a height of more than 60 feet.
The leaves are trifoliate. Rubber trees thrive the
best on islands and low ground near the rivers, where
the banks are inundated. Ground that is above
water at all times, or that has no drainage, is not
suitable. The peculiarity of the rubber tree, the
"hevea,"is that it will not grow satisfactorily on
cleared or open ground. It requires the shade of
other trees and still air from the time its growth be-
gins until it becomes an adult tree. Without these
conditions the supply of milk or sap is much affected.
The hevea requires about fifteen years to mature.
The area known to produce Para rubber amounts
to 1,500,000 square miles. It is believed that further
exploration will show that this area is underesti-
mated. On the river Acre, one of the tributaries of
the rives Purus, 200 trees yield as much as 3 tons of
rubber a year. Great quantities of hevea are known
to exist on the banks of the Japura, but that terri-
tory has not yet been opened.
It was at one time imagined that the excellence of
Para rubber was largely due to the kind of fuel used
in curing it. In the Amazon region the fuel used in a
clay funnel consists generally of the nuts of certain
palms. The reason these nuts are selected is because
they emit a continuous dense smoke and are more
portable than other obtainable fuel. The palms that
furnish the fuel were at one time transplanted in
Africa, with a view of making Para rubber there.
The experiment was unsuccessful. When none of the
palms is accessible bark and twigs are used as fuel.
All workmen in the forest carry a wood knife, the
blade of which is 26 inches long and 2 inches broad.
One of its principal uses is to cut the fuel for the
preparation of rubber. Owing to the damp climate,
the blades are electroplated to prevent their becom-
ing rusty before they are marketed. The knives,
which resemble the Cuban machete, are all imported
from the United States. The rubber collector carries
a small ax to chip a smooth surface on the bark be-
fore attaching a cup to the tree. The handling of the
ax requires skill in order not to injure the bark. A
smooth surface is made to prevent impurities mixing
with the sap. The cups are clay or tin. The former
are attached to the bark by means of a little clay.

Their weight, however, makes them inconvenient to
carry when the trees to be tapped are far apart.
The collector then prefers to carry tin cups. They
easily penetrate the bark by means of the sharp
edges and hold to the tree without the use of clay.
The use of the tin cup, however, is said to be injurious
to the tree.
Part of the collector's outfit consists of a light
gourd — large enough to carry the contents of from
">nu t<> Tim cups. A clay bowl is next required to re-
ceive the contents of the gourd, of sufficient size to
contain the product of several days' work before it is
i. The calabash tree provides calabashes, which
are employed to ladle the milk from the clay bowl
into the mold. A broad-bladed wooden paddle is used
as a mold and is made locally. This completes the
outfit for the rubber collector.
The collector has to use his knife to cut his way
through the undergrowth, and also to cut down a
sapling occasionally to bridge a rivulet. At times he
is knee-deep in ooze or up to his waist in water. On
arrival at a rubber tree, he chips away the rough
parts of the bark, makes a more or less smooth sur-
face, attaches a cup, and makes a small gash above
for the sap to fall into the cup, and repeats this pro-
cess in a line around the tree until he has attached six
or seven cups. Then he proceeds to the next tree
and does the same. He continues this process until
he lias tapped from 75 to 15(1 trees, which can be done
in a day if they are not too far apart. On the follow-
ing days the gashes in the trees are made a trifle
lower down than the first ones. Some collectors tap
the trees in the morning and return to collect the sap
in l be evening, whereas others tap in the evening and
collect in the morning. An expert gathers seven
pounds daily in the lower Amazon; in the upper
Amazon three times this amount is collected.
When the accumulation of rubber is sufficient —
usually in three or four days — the collector lights a
fire in the hut he has erected, places the funnel over
a fire, pours a thin coat of milk over the paddle and
holds it over the smoke to coagulate. The process is
repeated until a large cake has been formed. To
release the paddle from the cake it is necessary to
make a slit on one side. The paddle mold makes a
cake of uniform and even shape, and is in general use
in the State of Para. In other parts, a spit is placed
on two upright forked sticks and given a rotary mo-
tion. By this means the rubber is cured with greater
ease. Paddle smoked rubber is preferred, as it is
drier and seemingly more carefully cured.
Many attempts have been made to introduce im-
proved curing apparatus. Up to this writing, how-
ever, they have not been received with popular favor,
because the common method, although very primitive,
possesses the advantages of being simple and inex-
pensive. The process of curing rubber is extremely
injurious to the eyes. Many cases of total blindness
result therefrom.
There are three grades of Para rubber, viz. : fine,
medium and coarse. If rubber is not uniform and
contains impurities, it is classified as medium. The
coarse quality, or "Sernamby," consists of scraps
that have not been cured.
Insufficient labor is the most serious difficulty in the
rubber industry. It would scarcely seem advisable
to invest money in rubber estates, unless the owner
first can see his way clear to obtain sufficient labor
with which to collect the rubber. In reality, the
genuine owner of the produce of the forest is the col-
lector, not the landowner.
As a rule, the landowner makes advances to the
collectors for their outfit, food, etc., and in return
receives the rubber collected by them. He sells the
produce on the collector's account, retaining 20% for
himself, and continues making advances in such man-
ner that the collector always remains in his debt and
consequently in his service. It frequently happens,
however, that the collector takes the advance and
fraudulently disposes of the rubber to any buyer who
may be on hand. A great deal of leakage occurs in
this way, and no method of preventing it is in success-
ful practice. This is another of the difficulties of the
landed proprietor. One of the methods in practice
is to lease the trees in lots of 75, 150 or 200 at a given
sum per annum, and to stipulate that the lessee
should sell the rubber and purchase all his supplies
from the owner. The lessee works his lot to the ut-
most, and usually earns a handsome profit after pay-
ing the rent, and, although the owner does not obtain
the. full value of the lots rented, he makes up for it
by charging commission on goods supplied, etc.
The profits of the rubber industry would seem to
be large, because the employer keeps 20% and makes
about the same on the goods supplied the employes;
but it must be considered that out of 100 employes,
whose outfit and traveling expenses have been ad-
vanced, at least 75 die, desert, or return to their
homes on account of illness. The expense incurred
for them is accordingly a dead- loss, and when this is
deducted from the total income the profit is greatly
reduced.
The "aviador" is a person who advances supplies
and capital to the rubber collector in exchange for
rubber. The principal "aviador" resides at the
chief centers, and finances a number of small
"aviadores," who travel about in the rubber indus-
tries. The exporters of rubber are mostly agents of
United States and British importers. They buy from
the " aviadores " in the principal centers.
Signal Device for nines.*
By C. S. Heb/.ig.
Some time ago, in Mexico, our signal bells in a 700-
foot shaft caused us considerable annoyance by con-
tinually getting out of order, each time so delaying
our hoisting operations that we naturally desired to
remedy this evil. There were two ways open: either
to patch up the old bell, which was of the ordinary
pattern, every time it failed to work, or else to de-
vise some new arrangement. On consultation with
our foreman we devised a signal device which, during
the number of months I watched its operation, worked
satisfactorily, without once getting out of order.
We sought to produce a simple device, in which no
greater pull on the lever would be necessary from one
level than from another; to counterbalance inde-
pendently the weight of the pendant bell rope, so that
there would be no direct weight on the working parts
of the bell itself, and likewise to arrange it so as to
necessitate only a light pull on the lever in signaling;
and, finally, to make some sort of trip arrangement,
so that whenever the signaling lever underground
passed through a certain arc the signal would be
given in the engine room. By this means we wished
to obviate the ill effects of sudden heavy pulls and
rough usage in general, such as all signaling systems
encounter underground at the hands of careless or
mischievous employes.
The bell rop» we had in use was a galvanized iron
rope 372-inch in diameter ; and, after determining the
length needed, we calculated its weight, so that we
might be able to counterbalance it properly. On lo-
cating the bell in the engine room, a wire, W, is led
off horizontally, and, by means of a bell crank, is con-
nected to the main signal rope, M, passing down the
shaft (see Fig. 1). The weight w2 counterbalances M

and should be heavy enough to carry the wires back
to a normal position ; therefore, it must be equivalent
to the weight of the pendant rope, M, plus a factor to
overcome friction.
The working parts of the bell itself are shown in

B is a piece of fiat spring steel about 8 inches long,
at the end of which is the bearing surface b. D
serves as a hub, to which B and C are attached , C
being a flat spring similar to B, but about 12 to 14
inches long, at the end of which is the knocker E. It
should be observed that B is vertical, whereas C lies
"Canadian meeting, August, 1900, Am. Inst, M. E.
Hat. and that C should not be as heavy | a spring as B.
When the bell rope is pulled to signal the engineer,
the wire W moves in the direction of the arrow, and
the arm a, traveling downward in a circular path,
around f as a center, forces b to move downward
around D as a center, until the arcs in which they
are traveling diverge far enough for gravity to carry
B-C back again to its normal position, B being ar-
rested by the stop s ; however, the force with which
the arm Hies back causes the knocker to strike the
gong and thus give the signal. As soon as the bell
rope is released, the arm A is carried back to its
original position, and in so doing the triangular sur-
face on the end of a slides upon the inverted triangle
b (see Fig. 4), forcing it to one side (see Fig. 5), until
a rests in its normal position on top of b, when it is
ready for another pull, as shown in Fig. 3.
In counterbalancing the weight of the pendant bell
rope, sufficient weight must be added to the counter-
balance to bring the levers underground back into
position automatically. The counterweight may be
located at any convenient place on the headframe,
providing it is above the bell crank to which W is at-
tached.
In order to prevent the pull necessary for signaling
from becoming excessive, it is desirable to reduce
friction as much as possible. A force equivalent to a
10-pound weight should be sufficient for pulling the
levers in a well arranged signaling system. To ac-
complish this, I think it advisable to bring a bell rope
into proper alignment by means of plumb lines and to
hold the rope in position by means of old iron pipe 2
to 3 inches long, instead of by means of staples, as is
so commonly done. In inclined shafts the bell rope
should be supported at frequent intervals on some
form of roller. The spools on which connecting wire
comes make good rollers, in the absence of anything
better.
That there may be no mistake, the arm C should
be long enough, and the knocker E heavy enough to
cause their instant return to position when the paths
of a and b part company. For this purpose it is also
advisable to put a stop, Sj, below B, so that by no
possible chance can it fly beyond its balance point.
By increasing or diminishing the bearing of the tri-
angles a and b, the arc traveled can be changed. In
my opinion, it is not advisable to increase this bearing
above the inch mentioned before. The triangles, as
shown in section, Fig. 3, should have bases of about
J inch, with perpendiculars of f to 1 inch. The bear-
ings of the two points f and d should be good ones, so
that there will be no lateral motion, which might make
a fail to engage properly with b. Any play at d or
f is considerably magnified at the triangles ; but, by
making the bases of these triangles large enough, the
chances of their not working properly are greatly
lessened. By moving the position of h with respect
to the center f, the arc of pull underground necessary
to signal can be regulated.
The spring B must be quite stiff and of good ma-
terial ; but it must be borne in mind that the stiffer
the spring the heavier must be the weight w1,
and, in consequence, the greater the effort required
to pull the levers ; nevertheless, w, must be heavy
enough to bring back the wire W and to overcome
the resistance of the spring B. If the arm A is made
sufficiently heavy, the use of a counterweight (w3)
may be dispensed with, although it is preferable to
arrange as shown in Fig. 2 ; for by this means it can
be properly adjusted. If wx is too heavy, the arm A
has a tendency to pound against the stop s2. While
w, must not be too heavy, its weight must not be
cut down to such an extent as to impair the instant
return to position of the arm A.
The whole apparatus may be mounted on a board
and placed at some convenient spot in the engine
room.
Saving the Copper.
To the Editor : — The following is clipped from a
Utah paper :
In Butte City the Anaconda Co. realizes thousands of
dollars annually from the cupriferous waters by holding
thi9 water in tanks into which are plunged great quanti-
ties of scrap iron, etc. The iron is freed and a unit of
copper deposited in its place. At the Mikado mine re-
cently old pieces of submerged iron rails were found
changed to copper on the same chemical principle.
Might not the waters from those mines contain sufficient
copper in solution to make the proposition worth testing ?
The suggestion is a good one. The matter has been
given trial in this camp. There is copper in the water
below the mouth of the Starlus tunnel, at Bingham,
and Mr. Lee, the manager, some time ago had made
a series of small tanks ; he filled them with scrap tin
and ran the spring water through them, securing ac-
cumulation of precipitant. The water was clear, no
discoloration being perceptible, but carried an aver-
age of one-fourth of 1% copper. Within twenty-four
hours after the tin was immersed it showed precipi-
tation which accumulated, sloughed off and sank. _ In
seven to eight days the tin disappeared, being disin-
tegrated by the action of natural sulphuric acid in
the water. As a precipitating agent tin is superior
to naked iron, not enough oxidization taking place to
interfere with the process. The " plant" consisted of
five tanks, each 18 feet long, 12x12 inches wide and
deep, and one 4 feet long, 3 feet wide and 4 feet wide.

Gould & Curry Plant.
Among the new evidences of life on the Comstock,
Nevada, is the new concentrating plant of the Gould
&, Curry, now nearing completion. The accompany-
ing zincographis from an official drawing furnished
by Mr. Allan Kinkead, and reduced therefrom, the
scale being proportionately reduced — one-fourteenth
of an inch to the foot as it appears on this page. The
engraving will convey to practical miners a better
idea of the appearance and arrangement of the plant
than a page of description.
The new concentrating plant being erected by the
Gould & Curry G. M. Co. at Virginia, Nevada, will
the fifth floor below the bins. By this arrangement
it is claimed that 90% of the values can be recovered
by the one continuous operation. The mill will be
driven by electric power transmitted from the
Truckee river, a distance of 28 miles.
A Good Example.
The article on pages 149 and 152 of this issue de-
serves notice, being a plain statement of past and
existing conditions in the oldest continuously worked
gold mine in the United States, written by a man
fully familiar with the facts. The idea in referring to
it is to emphasize the thought that will naturally
occur to many California miners on reading Manager
Starr's statements, viz : that the Empire is but illus-
trative of what has been done in other instances, and
what can be done in many similar cases, when intelli-
gent use of money can make a permanent mine of an
abandoned property. The success of a mine is oft-
times measured by the faith of its owner or manager
in the permanency of the ore body. The biggest and
best mines in California to-day are mostly properties
that were thought to be worked out, like the Gwin
mine, which lay idle for sixteen years, till miners with
nerve and money put $150,000 into what proved to be
a big dividend-paying property. Similar mention
may be made of the Utica, Kennedy and other big
dividend producers, once abandoned, not from want
of ore, but because of cost of working. If one-half
the money spent in chasing rainbows in the land of
the Aurora Borealis were put into idle properties
along the axial mountain line of California, the result
would be far more satisfactory every way, and the
traveler through the Sierra foothills would not be out
of the sound of stamps along the entire 700 miles of
the State's length.
Mr. Starr's experience exemplifies the oft-forgotten
fact that in mining, as in other legitimate business,
economy simply means the judicious expenditure of
the same district as the Empire mine the ore shoot
of the North Star extends 2500 feet in depth, meas-
ured along the plane of the vein ; the Eureka-Idaho
shoot held its own uniformly over a distance of 5000
feet ; in the Maryland mine high-grade ore was found
on the same shoot at a vertical depth of 1500 feet,
and a small ore shoot was found near the bottom of
the Idaho shaft at a depth of 2200 feet. Gold quartz
veins in that vicinity show a vertical extension of 3500
feet, within which there is no evidence of any gradual
change in the character or quality of the ore. In the
same county, near Washington, good quartz is mined
600 feet below the river level in the Eagle Bird, and
2000 feet above the river level on the north ridges of
the river ; in that 2600 feet there being no distinct
difference in the quality of the ore.
This is a digression, but may be considered in con-
nection with Manager Starr's handling of the Empire
subsequent to the split in the large shoot, which pro-
duced the tenure of the ore by dividing it on three
veins, and which had, at the time, a depressing effect
regarding the stability of deep mining throughout the
State.
On this subject Waldemar Lindgren, in a work on
the quartz veins of Nevada county, Cal., correctly
says : "Many smaller veins carry only one ore shoot,
but in the larger fissures there are generally several
of them. There is a strong probability that in such
veins thorough exploration laterally or in depth will
develop new bodies of ore if the one on which exploita-
tion has been carried on is found to pinch out. The
question will naturally arise as to whether, with in-
creased depth and cost of mining, it will be a good
venture to carry on the necessary dead work. This
will have to be decided by the record of the mine and
the character of the fissure."
Colorado Minim* Decisions.
The Supreme Court of Colorado in the case of David-
son vs. Jennings holds: " Where the evidence failed
to show that a mine was being worked under a con-
tract by which C. was in any way liable for the labor
performed or material furnished for same, but
clearly established that it was being operated by
two others under a recorded lease, in which C. had
no interest, and such labor, etc., were furnished for
their exclusive use and benefit, C.'s interest in the
mine was not subject to a lien for same, though he
owned a one-fourth interest in the mine, and was
cognizant of the work, and to some extent, while em-
ployed as a bookkeeper for the lessees, took part in
its direction in their absence, and gave orders for
merchandise in their name, but failed to notify the
parties dealing with them of his true relation."
In the case of Schweitzer vs. Mansfield, the Court of
Appeals of Colorado decides that " a mechanic's lien
on a mining claim, showing that the complainants
were employed by and rendered services for the
"essees of the owner of the property, states no cause

have a daily capacity of 100 tons. The ore will be |
run from the lower tunnel (425-foot level) and dumped
over a grizzly into the mill bins, the coarse ore pass-
ing to a Gates rock breaker and broken to '2-inch
mesh. On the first floor below the bins the ore
passes to five heavy Kinkead mills where it is crushed
through 20-mesh screens, sized and carried to Frue
vanners on the second floor below the bins. The tail-
ings from the first set of vanners are then carried to
four Kinkead mills, located on the third floor below
the bins, where they are reground through 60-mesh
screens, sized and carried to the second set of van-
ners, located on the fourth floor below the bins. The
slimes are then separated from the sand and run into
a large V-shaped settling tank, 40 feet long, 10 feet
wide at the top and 10 feet deep, from which the
slimes are fed to the third set of vanners, located on
money : it is economy in making a mine, as in making
anything else of profit, to spend necessary money,
and no form of industry brings surer or more per-
manent return.
The first part of the article in last week's issue re-
lated to the early history of the mine. In this week's
installment of the article Mr. Starr makes reference
to the split in the Ophir vein. His ability to prove
that his theory regarding that split was correct, is of
value and encouragement as concerning deep mining
in California, and goes far towards favorable consid-
eration of similar conditions.
It is occasionally the experience of miners that
large bodies of ore pinch out with depth ; the Sierra
Buttes mine, in Sierra county, Cal., is an example ;
but it is a more common experience with large ore
shoots that they continue to the deepest levels. In
of action against the property."
The same court, in the case of the Little Veleria
G. M. & M. Co. , holds that ' ' a complaint by miners
to enforce a miner's lien against the owner of the
mine, alleging that they had been employed by sub-
lessee in accordance with the provisions of the original
lease, and that their wages had not been paid, but
failing to show that the owner of the claim was con-
nected with the contracted employment, or in any
manner obligated for the payment of their wages, is
insufficient to hold him or his interest in the prop-
erty." __

How to Find a Pocket
Written by a Prospector.
First. — Remember that the gold in the surround-
ing surface is the only guide to a pocket.
Second. — Never dig a hole on a quartz ledge with
the expectation of finding a pocket unless it will pros-
pect at the start.
Third. — When tracing for a pocket, if the gold is
smooth, leave it at once, for it's ten to one you will
never find it.
Fourth. — If your trace runs to a deep bed of clay,
don't lose much time in looking for the pocket.
Fifth. — Beware of serpentine traces. Most all will
prospect and not pocket.
Sixth. — Remember fifteen or twenty colors of gold
as fine as flour to the pan, and an occasional coarse
color as big as a pinhead, is a better trace to a pocket
than a single piece of gold worth $1, even if it is
rough.
Seventh. — The best place to look for pockets is in
a coarse-gold district. The pockets are larger and
as easily found.
Eighth. — Recollect that nine out of ten pocket
ledges do not crop out near the pocket.
Tracing. — Commence by panning the top of the
ground. It will prospect better there than deeper,
unless you are near the pocket or on flat ground.
Then go deeper, even to the bedrock. If on descend-
ing ground, face up hill, panning from right to left as
far out as you can get gold, and where you get- the
best prospect; move up the hill from that point, pan-
ning from right to left as before, and move up on the
best prospect. Keep this up until you get above the
prospects ; then go back where you got the last best
prospect, dig a small hole half way to the bedrock
and take a pan. Then take one on the bedrock, and
if the last prospects best, rest assured you are near
the pocket. From there trench up, and if you don't
find the ledge and prospects give out, trench across,
and you will be certain to find the ledge ; if you do
not find the pocket, trench both ways along the
ledge, panning every inch, and you will be certain to
find it, unless it has been distributed over the ground
you have traced by the rocks decaying and rain
washes. Where a pocket throws out a trace, you
will find it at the top of the bedrock, if there is any
left.
When you have taken out one pocket, note the
formation around it; follow that and you will be likely
to find another or a dozen. It is not advisable to sink
straight down very deep, unless it will prospect or
the formation runs that way, which can be deter-
mined by black rock, caused by fine stringers of iron
and quartz running towards the ledge ; where they
strike the ledge, pockets are liable to occur.
Pocket chimneys — like those on the mother lode or
any gold-bearing region — do not run straight down,
but angle on the ledge. Pocket shoots are often not
more than 1 foot wide, and even less. By the time
your shaft is down 8 or 10 feet, you will have cut
through your shoot and left it on the end of your shaft.
The same system described to find pockets holds good
in locating chimneys on millingilodes, if they contain
free gold orieven gold-bearing^sulphurets.

New Concentrating System.
Mine and mill managers, dealing with ores which
require concentration, are often harassed in their
efforts to secure concentrates of the greatest pos-
sible purity and carrying the highest attainable ore
values at least possible cost of extraction, if, when
the profitable point of extraction and purity has
been reached, values still remain in the tailings which
if in the mine treasury would insure a handsome
profit. In the majority of mining operations the
margin between profit and loss is a narrow one,
and this passing away of values is a source of worry.
More particularly does the above apply to those
who destructively handle gold ores which, in addition
to their free gold, carry auriferous metallic sulphides
of zinc, antimony, lead, iron, arsenic, copper, etc.,
sometimes singly, often containing a combination of
two or more, all of which slime readily under the im-
pact of a stamp ; and especially the more friable
ones, as of zinc and antimony.
In no branch of the mining industry has a greater
degree of intelligent thought and inventive genius
been brought to bear than in that involving the con-
centration of ores, and the mine owner heartily wel-
comes any suggestion or device which will enable him
to ever so slightly and profitably increase his percent-
age of values saved.
The Crown dry ore sizer and concentrator, illustra-
tions of which appear on this page, have been especi-
ally designed to secure a larger percentage of values.
In these machines are embodied the practical re-
sults of long continued and expensive tests on the
belt, traveling through a closed box having an air
chamber under the superior portion of the belt. The
concentrator box is fastened to a shaking table to
which is given a compound motion to keep the ore
particles actively vibrating on the belt, and is de-
signed to insure perfect concentration. The concen-
trator belt travels equal distances in equal times, an
accompanying device being intended to eliminate all
slippage. The travel of the belt can be quickly
varied and the table elevated or depressed, as may
be best suited to obtain the most profitable results
from the different sized ore grains being concen-
trated. At the head or elevated end of the concen-
trator is placed a blower which discharges itself
horizontally into the air chamber under the corru-
gated belt. This air pressure may be regulated from
an ounce to the smallest fraction thereof to each
square inch of belt surface, as may be found to be
most suitable to the gravity and size of the ore
grains. The air pressure can relieve itself only
through the interstices of the woven belt, running
at an angle of about 15°, the horizontal air column
strikes it at an acute angle, and, passing through
the belt, deflects the slower
moving, light and worthless
grains from the perpendicu-
lar, causing them to travel
toward the lower or waste
discharge. The heavier and
valuable particles, being un-
affected by the air current,
are carried by the belt to
the upper or concentrate
discharge. As the influence
of specific gravity acts more
freely in the rarified medium
tion. In the complete process the general practice
is reversed, in that the ore is worked for the free
gold — if the tailings show any — after, instead of be-
fore, concentration.
' ' The ores are handled automatically from breaker
to waste dumps. A limited personal supervision only
is necessary to attend to the details of stopping,
starting and regulating machinery and concentrator,
air currents, feeds, elevation and action. The feeds
are designed to be so adjusted that precision and uni-
formity are assured. When the machines are in
action all floating dust particles are absorbed by a
dust collector, much to the comfort of the millman
and the increased longevity and cleanliness of the
machinery. Compared with their tonnage capacity,
the machines require but a small area under cover
and but a moderate expenditure of power. All
swinging points are ball- bearing and other bearings
are dust proof."
If all that is claimed by the manufacturers be
true, the sizer and concentrator should prove of
value to those operating milling plants in arid re-
gions, where the water supply is scarce, impure or
Concentrator.
Sizer.
part of the inventor, F. W. Wood, based upon the
proper application of the following principles :
First. — That bodies of unequal sizes, but equal fall-
ing weights, will fall together.
Second. — That bodies of equal sizes, but unequal
falling weights, will not fall together.
Third. — That the influence of specific gravity upon
a falling body increases or decreases proportionally
to the density of the medium traversed by the body.
Fourth. — That all mineral particles, however finely
divided, will, in falling, if of equal size and left free to
act, arrange themselves in accordance with their
specific gravities.
In the Crown dry ore milling process the ore is
first passed through the rock breaker, thence through
a series of rolls gauged to give pulp of the desired
fineness and without grinding or crushing the sul-
phides to a sliming powder. The pulped ore is con-
veyed by a carrier belt to the " sizer," which consists
of a dust-tight box containing screens of from 40 to
180 mesh (the mesh sizes can be varied to suit par-
ticular ores). By a simple mechanism and small ex-
penditure of power the sizer is given a rapid oscil-
latory motion, and each screen discharges its special
sized grains into a separate bin. An automatic at-
tachment takes assay samples from the separate dis-
charges at regular intervals. In the sizer the ore
particles have been rearranged and classified from :
First. — Bodies having unequal sizes, but equal fall-
ing weights, into —
Second. — Bodies having equal sizes, but unequal
falling weights.
From the sizer bins the assorted particles are taken
to the concentrators by carrier belts, the sized
grains being concentrated separately ; but all of the
concentrates are delivered into one receptacle, and
all of the waste is discharged into one dump, unless
for any reason it is desired to keep the sizes segre-
gated.
The concentrator consists of a woven corrugated
— air — than in the denser medium — water — satisfac-
tory concentration is designed to be effected, the fin-
est particles being recovered.
The manufacturers are of the belief that the sul-
phides saved will be from 95% to 98£% of the total
quantity contained in the ore, even though such
sulphides should have the greatest tendency to slime.
They also claim that in purity or freedom from
worthless matter the concentrates will reach 90%
to 95%. Any system of rolling or crushing will
leave some grains of matrix with adherent part-
icles of sulphides or free gold, which pass over
into the concentrates, and, to this extent, debase
the product.
Numerous assays indicate that, with some excep-
tions, the valuable contents of ores worked will be
found in a well-defined series of classified particles.
In some ores these values will be in the coarser
series ; in other ores they will be found in the finer
series, and in still other ores in the intermediate
series. As assay tests are taken at the sizer, only
those sizes carrying value are put through the con-
centrator. The worthless sizes are consigned to the
waste dump, there being, then, a large amount of
material upon which no further expense is in-
curred.
The manufacturers say " that among the sizes show-
ing values it will be found that one or more of these
carry the bulk of the sulphides, while the other sizes
will carry the largest percentage of free gold in ores.
Those sizes carrying free gold can be treated either
before or after concentration — preferably after — and
a larger value recovered than if treated while asso-
ciated with the sulphides ; and the loss of free gold
floated away by the slimes, or the loss of mercury
and amalgam by being scoured, sickened or floured
and carried off in the tailings, is reduced almost to
zero."
They claim that the Crown sizer and concentrator
can be profitably attached to most mills now in opera-
expensive.
The manufacturers say: "In putting beach and
river sands through the machines the separation of
gold and black sand grains from the siliceous par-
ticles was so perfect as to leave nothing to be de-
sired but a higher value in the crude sands."
They also claim that "from dry placer gravel
sands all but a very small fraction of the gold is re-
deemed." It has ordinarily been found impossible to
economically extract the finer gold particles from
dry placer sands.
Further claim is made that " where pulps charged
with cupriferous pyrites or metallic copper particles
have been treated by this process the tailings have
proved barren when assayed."
The machines are manufactured and operated by
the Crown G-old Milling Co. at their factory, 23 Ste-
venson street, San Francisco, where they can be
seen in operation and may be subjected to any desired
test. The office of the company is at 230 Post
street, San Francisco, Cal.
This time it is smelting that is to be " revolution-
ized." A company in New York is reported to be
operating on a small scale a new process for the
manufacture of oxygen, by which with the assistance
of liquid air and an apparatus which can be placed on
the stack of a smelter, oxygen can be made at a low
cost. Then it is sprayed over the coke in a furnace,
and one ton of coke, it is claimed, can be made to do
the work of three tons, so hugely is the work of com-
bustion aided by the added oxygen.

NTMliKK III.
All water jackets have a projection I inches above
their tops iii the center. Tliis projection is open on
top and has a circular bole in front in which the waste
water pipe is inserted. The feed-water pipe is in-
serted through the open top and reaches about half
way down in the projection. Some metallurgical au-
thors insist that the coldest water should be intro-
duced at the bottom of the jackets. 1 am of a differ-
ipinion. The feed water is kept near, but below,
the boiling point.
The height of the water jackets is 11 inches in the
ease of the large size (42"xl20") furnaces, and S I
inches in that of the smaller-sized (42"xll)2"). Such
high jackets are unwieldy to handle ; the former are,
therefore, preferable.
The width of the side jackets of the large furnaces
is 20 inches, that of the smaller is 17 inches ; hence,
the length of the furnace section can be easily ob-
tained by multiplying the width of the side jackets by
their number.
The front and back jackets arc 27 and 34 inches
wide at the bottom, respectively, and 87 inches wide
at the top. The front jackets are made 10 inches
shorter at the bottom than the back jackets, in order
to be able to place a slag tap (slag notch or tap
jacket) on the dam under them. The slag tap is a
small water jacket of cast iron, or, better, of bronze,
26 inches long by 14 inches high, with 3A inches of
water space, and a conical hole cored out in the cen-
ter, which has a diameter of 2A inches toward the in-
terior of the surface and 5 inches outside. Through
this hole the slag is tapped. The jackets of the
larger furnaces have a bosh of 6 inches (or an angle
of 7 11° from the horizontal) all around, thus making
the section of the furnaces above the water jackets
54x132 inches. Likewise have the jackets of the
smaller furnaces a bosh of 9 inches all around (or an
angle of 73A° from the horizontal), affording an area
of iid.\]20 inches above the jackets. A flatter bosh
is to be avoided.
The front and back jackets are not set between the
side jackets, but lean or butt against them on the
outside, and are wide enough to cover the narrow
ends of the side jackets. They are held together by
means of 1-inch bolts passing through wedge-shaped
washers (wedge blocks), which are inserted in lugs
cast on the jackets. This arrangement allows con-
traction and expansion of bolts without breaking off
the lugs. Where blast of a high pressure is used,
extra binders must be laid around the jackets.
By giving the smaller furnaces the same number of
tuyeres as the large ones, namely, twelve, it was
thought that they could be made to smelt the same
number of charges as the larger ones. Ordinarily,
this was not the case.
Cast iron water jackets are preferably used by lead
smelters on account of their cheapness and the ease
with which they can be handled. They are especially
of advantage when the water is bad, for, if one
breaks, there is not much lost, and it is an easy mat-
ter to replace it. This is different with wrought iron
and steel jackets. As the sections cannot be fitted
so snugly as cast iron ones, it is customary to make
the whole side of a furnace one water jacket, to avoid
too many joints. With bad water, they do not last
much loDger than cast iron, and it is then quite
troublesome, and involves a great loss of time to re-
place leakly ones.
Good cast iron jackets can, however, not be made
by any founder; it requires a great deal of experience
and care, a fact which the Colorado founders, who
now turn out the best work, have found out long ago.
The water jackets made by the local foundry at Mon-
terey were worthless, both on account of the quality
of the iron and the uneven thickness of the castings.
It is a strange fact that I never saw a cast iron
water jacket in a copper smelter; they use wrought
iron or rolled steel plate altogether. At the Heinze
smelter, Butte, Montana, cast iron jackets are used.
Cast steel jackets, if such are made, cannot be
trusted, as the castings frequently contain air holes,
which give rise to leakage.
The shaft of the furnace with the chimney sur-
mounting it is built of red brick, with an interior lin-
ing of refractory brick, and rests on four hollow cast
iron columns, weighing about 800 pounds each. There
are three methods in use to support the shaft: —
First, a cast iron mantle frame is bolted on the
caps of the columns, and brick arches are thrown
across from column to column on which the upper
masonry rests, the space between mantle frame and
arch being also filled out with brickwork.
Secondly, a framework of three parallel I-beams
bolted together is fastened to the tops of the columns,
and cast iron deck plates of the width of the masonry
are bolted to the I-beams; on thesedeck plates arches
are sprung the same as before, and on these the
upper masonry rests.
Thirdly, cast iron shoes, having the shape of skew-
backs, are fastened to the tops of the columns and
held together by two stout cords or tension rods
with screwed ends, and from these shoes the arches
are built up. This latter plan has been put in
Eractice at the Germania Lead Works. Utah, by the
tenver Engineering Works, and seems to be a good
One if the arches do not get distorted by variations in
temperature.
The two first plans 1 have tried myself, and I do
not know now which is the worse oi the two. Both
have- their bad sides. The I-beams are much affected
by the radiated heat of the furnaces, and after along
use get out shape with corresponding injury to the
masonry. Therefore 1 discarded them. On the other
hand, the cast iron mantle frames are subject to
corrosion by the smelting material, and are liable to
In- cracked by the heat, in which case their function
becomes unsafe.
The furnaces at smelter No. 3 were, however, all
provided with mantle frames alter rebuilding,
The furnace walls are in most cases too thin: they
consist of is inches of red brick externally, and !)
inches of firebrick lining internally. This lining rests
on the few courses of firebrick intervening between
jackets and mantle frame. To afford more solidity
to the brickwork, the firebricks should bo tied at
every third or fourth course with the red brick.
The shaft is bound by heavy tension rods, running
through cast iron angle pieces, at every foot up to the
charge floor, above that at greater distances.
The shaft is carried up straight to about 6 or 7 feet
above the charge floor, leaving spacious doors in the
long sides, and then contracts gradually to the size
of the chimney. The doors are not directly opposite
one another, but diagonally, in order to prevent the
feeders from throwing the charge all in one place.
The doorsill is about 9 inches above the charge floor,
to compel the feeder to shovel in the charge and not
scrape or push it in.
The effective height of the smelting column, that is,
the distance between the centers of the tuyeres and
the charge doorsill, is between 13 feet 10J inches and
14 feet 1 inch. The original furnaces had a higher
smelting column, but the filling up with slag in front
of the furnace building to a higher level than the
furnace floor caused the rainwater to flood it in the
wet season, and necessitated the raising of the
hearths above the high-water mark. This was done
without raising the charge floor, hence the loss in
height.
The down-comer or down-take is carried from an
opening in the back wall of the chimney into the flue
underneath the back part of the charge floor, and
behind the furnaces, in the same manner as at smelter
No. 2. The flue runs parallel to the back end of the
furnaces some distance beyond the furnace building
proper, then turns a rectangle, and connects with a
brick chimney 130 feet high. The discharge openings
of the flue through which the dust is raked out are
in the side opposite the one running through the
furnace shed, and are facing the ore bed shed. The
main blast pipe is carried overhead from the engine
room through the passage into the furnace shed along
the rear of the furnaces to the farthest one, where it
makes connection with the reserve blower. The blast
main is tapped for joining on the distributing or bustle
pipe opposite the center line of each furnace. In the
connection between the main pipe and the bustle pipe
a gate valve (blast gate) is inserted, for turning on,
lowering, or shutting off the blast. This arrange-
ment repeats itself in every American smelter. Cor-
responding to the tuyeres, there are stubs attached
to the bottom of the bustle pipe, which are connected
with the tuyere pipes or nozzles by means of a stout
canvas hose (16-ounce duck), made air-tight by being
soaked in raw linseed oil and dried. Galvanized
tuyere pipes have been abolished on account of their
frail construction; the patented forms of tuyere pipes
are too complicated for the simple-minded people of
the country; and cast iron ones are too heavy and
clumsy. So a tuyere pipe of cast steel has been
adopted, which is similar in construction to the Davies
tuyere pipe made by Fraser & Chalmers. It has a
2-inch slag escape at the bottom, threaded inside, and
ordinarily closed by screwing in a wooden plug, and
a detachable cap with a peep-hole at the back. The
mouth fits over a sleeve against the shoulder of a
steel thimble or bushing that is inserted into the
tuyere opening and made airtight by packing with
asbestos paper or even clay mortar. This thimble,
which, in reality, might be called a tuyere, is 3J
inches diameter at its mouth.
Brass would be the proper material for these de-
vices if it were not coveted so much by petty thieves.
The water is distributed to the furnaces in a similar
manner as the blast. The main pipe is conducted
overhead from the water tank along the front of the
furnaces, and at each furnace is tapped for joining on
the feed pipe, which is of reduced section. It is not
sufficient to provide water for the jackets only, but
there must be extra nipples with rubber hose at-
tached to the feed pipe in case of accident. Water
should of necessity be plentiful about a furnace.
Adjoining to and connected with the furnace shed
is the bullion shed, is which six broad gauge cars may
be placed to load bullion on. Annexed to one side of
this bullion shed is another shed containing the bul-
lion remelting plant, for short called the refinery,"
in which all the furnace bullion is melted over again,
and the impurities are skimmed off. The plant con-
sists of two cast iron kettles or pots, 6 feet 4 inches
in diameter, and 36 inches deep, with a common iron
smokestack between them.

New Metallurgical Process.
The current number of the Engineering Magazine
has extended notice of Br. (ioldschmit's new method
of welding rails, in which he makes use of the great
heat developed by aluminum when it combines with
oxygen furnished by a metallic oxide. In the process
of welding which he uses at present, the ends of the
rails are brought together in a crucible, in which is
then placed a quantity of finely divided aluminum and
iron ore. The rails, previously planed at the ends,
are pressed together tightly and the mixture ignited ;
the heat produced is sufficient to make a good weld.
the more so as the high temperature causes an ex-
pansion of the rails and brings them firmly together.
When aluminum and oxygen enter into chemical
combination, there is evolved a higher temperature
than can be generated in any other artificial way ex-
cept by electric methods. For a long time this fact
was not generally recognized, partly because alu-
minum was more or less of a chemical curiosity and
its production was confined to the laboratory ; but of
recent years, since it has become an important tech-
nical product, its properties have been more widely
investigated and new facts concerning it discovered.
The work of Dr. Hans Goldschmidt in this field has
laid the foundation for an important new industry, to
which the name of " Aluminothermie " has been given.
This term covers, in general, those processes in which
high temperatures are produced by the combination
of oxygen and aluminum, and various developments of
Dr. Goldschmidt's inventions are described by him in
a recent issue of Gluckauf.
The chemical reactions involved, says the Engineer-
ing Magazine, are very simple. Oxygen is not taken
from the air, but is used as combined with the metals
in the form of metallic oxides. As an example, take
iron oxide, of common occurrence in nature as some
of the iron ores. If metallic aluminum, finely divided,
be mixed with a powdered iron ore and a reaction
made to take place, the resulting products will be
aluminum oxide and metallic iron, and at the same
time a very high temperature will be evolved.
The problem has been to start the reaction. Most
of these mixtures of metallic oxides and aluminum
will burn only at high temperatures. They could be
stirred with a glowing rod without any combustion
taking place. The application of external heat would
not answer, because the heat which would cause the
mixture to burn would damage the crucible contain-
ing it.
A solution of the difficulty was reached when it was
found that there is a class of oxides, which, when
mixed with aluminum, are easily ignited at a low tem-
perature, and after ignition evolve very high temper-
atures. It is only necessary, then, to sprinkle an
easily inflammable mixture, such as barium super-
oxide and aluminum, on the refractory one, and then
light the former, which can be done most easily with
a large match. The kindling mixture will burn and
generate a high temperature, and so set the main
mixture on fire. More of the latter can be added
from time to time, as desired, and will react with the
evolution of as high temperatures as the combustion
of the first portion generated.
There is thus afforded an extremely convenient
means of obtaining great heating effects at any place,
without the use of machinery or any complicated ap-
paratus. The temperatures resulting from the reac-
tions described can only be estimated, as there are
no means of determining them exactly, but they are
considerably over 2000° C.
The practical applications of this process already
embrace wide limits. A direct result of the chemical
reactions is the separation of the metals from their
oxides in a pure state. The combinations take place
in a regular way, according to chemical laws, but the
mixtures are always made with an excess of oxide, so
that all the aluminum will be oxidized and no metallic
aluminum left to form alloys with the other metals.
The process is applied with special advantage to
metals which it has not before been possible to isolate
completely, but which now can be separated in an en-
tirely pure state, free from even carbon. Among
such metals, one of the most important in a metallur-
gical way is chromium. Almost all the chromium
which has heretofore been used in steel metallurgy
contains a considerable percentage of carbon, and is
to be regarded as chromium carbide. All the chrome
steels are, therefore, strictly speaking, chromium
carbide steels, and have their properties materially
influenced by the combined carbon. But it is now
possible with the pure chromium to form steel alloys
whose properties are decidedly different from the old
chrome steels, and which can also be made to contain
larger percentages of chromium.
In the same way pure manganese is produced,
which finds a wide application in the making of man-
ganese bronzes, free from iron, and, also, in special
manganese steels. This pure manganese possesses
the desirable property of not disintegrating on ex-
posure to the air, as does the ordinary carboniferous
manganese, and it also particularly distinguishes it-
self by its easy formation of alloys with molten cop-
per, tin, zinc and other metals. Copper alloys con-
taining 20, 30, 50 and even higher percentages of
manganese are formed with extreme ease by the pure
manganese.
Among other metals of growing importance in met-

allurgy which are prepared by this process may be
mentioned titanium and boron.
A most important bye-product is the melted alu-
minum oxide, which is formed simultaneously with the
separation of the pure metals. This product is really
an artificial corundum and has been called "corubin."
It is distinguished by its great hardness, and for
grinding and polishing purposes far surpasses natural
corundum and emery.
But perhaps the most important practical applica-
tion which is made of this process is in welding. For
this purpose there is used a mixture called " ther-
mit, " consisting essentially of iron oxide and alumi-
num, which is kindled by one of the easily burning
mixtures previously described, and burns with the
evolution of great heat in a specially prepared cru-
cible made of corubin, magnesia, or some other very
refractory material. The surfaces of the parts which
are to be welded are carefully cleaned and polished,
and pressed together by a framework with screws.
A mold is placed around the joint and into it is poured
the fluid mass from the crucible. The heat and pres-
sure do the rest. In the crucible, before pouring,
there are two strata. The lower consists of fluid iron
and the upper one of the lighter melted aluminum
oxide. When the pouring begins, the alumina which
first flows into the mold quickly cools and forms a
thin layer on its inner walls as well as on the pieces
which are being welded. The rest of the alumina and
all the iron remain fluid for a short time in the mold.
In consequence of the solid coating of alumina, the
molten iron does not touch the surfaces of the mold
and the welded piece, and when the whole mass has
cooled down, it can be removed by a couple of light
hammer blows. The welded piece has not been de-
formed by the attachment of any fused iron, and the
mold is not injured and can be used repeatedly.
By many experiments it has been carefully deter-
mined just how much of the heating mixture is neces-
sary for a weld of a given size, and what the capacity
of the mold must be. In this way it is possible to
know beforehand the amount of heat required for a
weld. This is an advantage which no other welding
process possesses, as these are all based on empirical
methods and require an experienced eye and hand to
be carried out successfully. The new process can be
applied by ordinary workmen, after a very little
practice. Another advantage of the new method is
that the heat is concentrated just at the place where
it is needed.
This process is particularly applicable to rails of
electric railways and to pipes for steam, gas and wa-
ter, as these can all be welded in any position and at
the places where they are in use.
The molten iron can also be used to repair defective
or broken parts, by casting it right onto the original
piece and working it into proper shape after cooling.
Only a few of the leading applications of this pro-
cess have here been given, but there are enough to
show that it bids fair to mark a distinct advance in
metallurgical fields.
Notes on the Occurrence of Platinum
in North America.
By Dr. David T. Day, Chief of the Division of Mineral Resources,
U. S. Geological Survey.
In the summer of 1898 demand suddenly arose for
commercial quantities of the element osmium. At
least half a ton was wanted for initiating a new in-
candescent light. This led the writer to exam-
ine as many localities as possible where plati-
num had been reported, to determine whether osmi-
ridium was contained in the crude platinum. With
the co-operation of the firm most interested, the
Welsbach Light Co., and in company with its presi-
dent, Colonel William Barrows, I visited most of the
localities where platinum has proved plentiful. I
also wrote to every available placer mine in the West
for samples of the heaviest sands, in order to test
them for platinum.
The references to the occurrence of platinum in
this country as given in scientific journals include
two interesting observations in the East. One is of
a nugget described by Peter Collier of Washington,
D. C. (Am. Jour. Sci., 1881, Vol. 21, p. 123), said to
have been found on land adjacent to the village of
Plattsburgh, New York. It weighed 104.4 grammes
and contained sufficient chromite to reduce the spe-
cific gravity from 17.35 for the heaviest portion to
10.446 for the average of the nugget. The nugget
gave "unmistakable evidence of osmium."
Messrs. William E. Hidden and J. H. Pratt have
(Am. Jour, Sci., 1898, Vol. 6, pp. 381 and 467) found
sperrylite — platinum arsenide — in placers in several
points in the Cowee valley of North Carolina. The
conditions tend to the belief that the source of this
rock is a ledge of impure rhodolite and biotite con-
taining much of disseminated iron sulphides — condi-
tions much like those at Sudbury, Canada. In spite
of unsubstantiated reports of platinum occurring in
place in certain specific locations in the Catskills in
New York, and in granite near Philadelphia, and
again near Port Deposit, Maryland, the only locali-
ties where platinum is known to occur in North
America, otherwise than as a mineral curiosity, are
California, Oregon and British Columbia.
As early as 1852 Prof. W. P. Blake called atten-
tion to the existence of platinum at Port Orford, on
the Oregon coast (Am. Jour. Sci., Second Series,
Vol. 18, p. 156, and Vol. 22, p. 8), and noted that the
platinum equaled from 10% to 30% of gold. This
article seems to be the original source of the state-
ment that the proportion of platinum to gold in-
creased northward. B. Silliman (Am. Jour. Sci.,
Third Series, Vol. 6, p. 132), in his mineralogic notes
on California, etc., extended our knowledge to the
occurrence of platinum in the older deep placers
worked by the hydraulic process in Butte county.
He also notes the occurrence of iridosmine with the
platinum.
The various notes concerning the finding of plati-
num on the Pacific coast have been well summarized
in the publication of the California State Mineralogist
and show that platinum has been found at many
places on the Pacific beach from as far south as Santa
Barbara county northward to the mouth of the
Columbia. Indefinite reports have been made of its
occurrence farther north on the Washington beach,
but the amount is certainly not great. The principal
beaches where platinum has been reported are :
Beginning at the south, Santa Barbara, Lompoc,
the beaches of San Luis Obispo county, Santa Cruz,
and occasionally between Santa Cruz and the Golden
Gate. In accordance with Blake's statement the
richest beaches are farther north, in Humboldt and
Del Norte counties. The beach mines of Gold Bluff,
north of Areata, Big Lagoon, Stone Lagoon, Little
River, Crescent City, and at Gold Beach and Port
Orford,' in Coos county, Oregon, have all yielded
platinum in more than experimental quantities. Still
farther north platinum is found at Yaquina Beach,
Oregon, but the sands are poor. Port Orford has
proven, perhaps, the richest beach. Sharpless and
Winchell have made an unusually careful examination
of the sands at Brandon, on the Oregon beach. They
almost invariably found platinum, but the proportion
was not so encouraging as with less careful workers.
All of this beach platinum is discouragingly fine and
difficult to save.
Most of the platinum product has come from in-
land mines, where the platinum is comparatively
coarse. It has become well known in the placers of
the American river, and in Plumas, Shasta, Trinity
and Siskiyou counties, California. The Bee Gum dis-
trict, in Shasta county, the Hay Pork district, in
Trinity county, and along the Trinity from Chapman's
mine, north of Junction City, north beyond North
Fork, are most promising.
While platinum metals are so frequently found in
many of the gold placers in the region including
Trinity, Shasta and Siskiyou counties, this is by no
means universally true. There seems, for example,
to be no platinum in the Weaverville placers on the
Trinity. The platinum-bearing placers confirm the
generally accepted idea that the platinum originates
in the serpentine rock in which this county abounds,
for the platinum gravels are sure to be closely asso-
ciated with some prominent serpentine ridge. Nev-
ertheless, no platinum has yet been found in place in
that region.
A hurried trip through this region enabled the
writer to learn — by the analytical aid of Dr. Wald-
ron Sharpleigh — that in the Bee Gum district of
Shasta county, at Hay Fork and at Chapman's mine,
on the Trinity, osmiridium makes up, perhaps, the
greater part of the mixture of platinum metals. At
Chapman's mine Colonel Barrows obtained thirty
ounces of small nuggets, averaging J inch in diame-
ter, which seemed altogether too hard for platinum,
and yet, in very much larger grains than is usual for
osmiridium, which has the habit of occurring in very
small scales. Dr. Sharpleigh has shown that these
nuggets yield a small amount of platinum on treat-
ment with aqua regia, and then fall apart in the ordi-
nary scales of osmiridium. Dr. Sharpleigh has found
that the Pacific beach platinum often contains more
than 90% of osmiridium. This is a sufficient reason
why so little effort has been made to mine platinum,
Granite creek near its junction with the Tulameen
Fork, in British Columbia, it was estimated that the
placers contained about one-fifth as much platinum
as gold. I could get no test for osmium, but Dr.
Hoffman of the Canadian Geological Survey has found
samples of platinum yielding as high as 25%, and on
the average about 10%, of osmiridium.
In further search for the platinum metals the
writer collected heavy sands from the placer mines
in California, Oregon, Washington, Idaho, Montana
and Alaska. These samples averaged four pounds in
weight. The sand was first separated by ordinary
assay sieve into nine sizes, coarser than 20-mesh,
through 20, 40, 60, 80, 100, 120, 160 and then 200-
mesh. Each size was then in good condition for easy
separation of the very magnetic portion by a rude
form of separator. By limiting the magnetic sepa-
ration to the very magnetic particles very little gold
or platinum was found on panning the magnetic por-
tions. By panning each size and then counting the
flakes of gold and platinum, or weighing where the
amount was considerable, a fair idea of the propor-
tion of platinum to gold was obtained. As the siev-
ing was carried to such uniform sizes, it was possible
by counting weighed amounts to estimate the unit
weights of flakes of the different sizes, and thus to
approximate roughly the total weight of gold and
I platinum obtained.
A number of concentrates collected by Mr. A. H.
Brooks of the Geological Survey from the Tanana
! river district in Alaska, and also the beach sands
I from Cape Nome, by Messrs. Brooks and Schrader,
i showed no platinum.
The total result shows that if all the sands exam-
ined were considered together there would be about
half as much of platinum metals as of gold.
May's Gold Extraction Process.
From the explanation of the process given by the
officials of the company, it appears that the ore, after
being crushed, is exposed to the action of a solution
of caustic alkalis or alkaline carbonates (used either
separately or mixed) contained in specially designed
vats, the solution being heated by waste steam, and
is kept in a state of agitation, which is effected either
by the rotation or the internal mechanical arrange-
ment of the vats. The period required for treatment
is said to be from one to three hours, according to
the rebellious nature of the ore. By this means the
extraction of the total gold contents from refrac-
tory ores is facilitated, and a large proportion of the
precious metal, which would otherwise be irrecover-
able, is saved. The ores, slimes, etc., after being sub-
jected to the action of the chemicals, are then ready
for amalgamation and are run off in the amalgamator
into the settler. The amalgam is collected at intervals
and passed through the clean-up pan, and is then
ready for retorting and separation of the metal in the
ordinary manner, the residues passing into a pit.
It is claimed that the entire process is continuous,
the time required being but from eight to ten hours
from the first operation to the extraction of the gold
and silver. It was stated that the average cost is
only 2s. 6d. per ton of ore treated. — London Mining

Compound Duplex Pressure Pump for Mines.
The illustration herewith is for a compound duplex
pressure pump to develop a maximum pressure of 700
pounds per square inch. The liquid end is of the end-
packed trombone style, the cylinders being made of
special metal. Mounted thereupon are separate
chambers for the location of the valves ; chambers
are also constructed of special metal and designed
with a view of facilitating quick access for the in-
spection of the valves. The valves are of the hydrau-
for until recently this osmiridium has been of practi-
cally no value.
At the time of this visit platinum was also noticed
in the placers near Grant's Pass, Oregon, and by
examining great numbers of black sands traces of
platinum were found in the Snake river from Bar-
kersville to Lewston, and in a sand reported from
Miles City, Montana.*

proved rich last year— is the only beach
ground of much value this year, and will
bo thoroughly worked out by the close of
the season. At Topkok a small strip Of

grantors have sunk an incline shaft upon
land east of the Pennsylvania mine, the
shaft being part of the W. Y. O. D. mine.
The plaintiffs claim that within the past
two years the defendants have by means
of shafts, levels and stopes, and particu-
larly in the 800 and 900 stopes, illegally
intersected veins and ledges which have
their tops or apexes within the lines of the
Pennsylvania M. Co. It is claimed that
the defendants have unlawfully taken out
and converted to their own use 30,000 tons
of rock valued at $600,000. The Pennsyl-
vania M. Co. asks that $600,000 and the
costs of the suit be awarded them as judg-
ment for the damages sustained; that the
W. Y. O. D. mine workers be enjoined
from entering ground alleged to be the
property of the Pennsylvania Co., and

The Puente Oil Co. owns wells in tho
Puente oil field and the refinery at Chiuo,
the only refinery in southern California
in which illuminating oil is made. Tho
company turned out during July 5000 gal-

and engine distillate. Tho oil is of so vol-
atile a nature as to be too explosive to make
the best of fuel, and the refinery makes it
possible to take out the volatile portion in
the form of distillates and leave tho re-
siduum for fuel use. Tho Standard Oil
Co. takes all the refined oil produced at a
stipulated price and distributes it, it being
claimed that it is first mixed with Eastern
oil. The oil refined by the Puente Oil Co.
is taken from its own wells in the Puente
field, and it is piped by gravity to the re-
finery.
At Gold mountain water is developed

CLEAR CREEK COUNTY.
(Special Correspondence). — The Gold
Fissure G. M. Co., in sinking their shaft
have encountered ore at 40 feet, which is
undoubtedly the extension of the Tenth
Legion lode, whose property end lines
with the Gold Fissure. The shaft of the
latter is being well timbered, and a plant
of hoisting and air compressor machinery
is being installed. The calculation is to
sink to 800 feet depth. G. A. Bristol and
C. B. Steele are managers.
Empire, Aug. 4.
F. R. Carpenter is engineering the es-
tablishment of a 240 heavy-weight stamp
mill at the Alice mine in the Yankee hill
belt of veins and plans to treat. 1000 tons
of ore daily. The 240 stamps will be of
1000-pound weight each and have a low
drop. The ore averages about $5 per ton
in gold, a portion of which can be saved
by plate amalgamation. The tailings
from the stamp batteries will make a de-
sirable flux, which will be treated by py-
ritic smelter, the values being run into a
matte.
Near Georgetown, work will soon begin
on the Mendota shaft. The workings on

DOLORES COUNTY.
(Special Correspondence). — The three
main groups of mines at Rico — the Enter-
prise, Rico-Aspen and Black hawk — pro-
duce an excellent grade of ore, running
100 ounces silver, two and one-half to five
ounces gold and 15% lead. It is most in-
teresting to observe the increasing im-
portance of the gold product of these time-
honored silver mines. With the exception
of the three groups named, nearly all the
properties of Rico district are still in the
hands of the original locators, who have
hung tenaciously to their holdings through
years of depression and discouragement.
It is pleasant to observe a more hopeful
condition here, which presages an oppor-
tunity for many of the old timers as well
as for capital seeking to invest. Con-
ditions at Rico are favorable. The mines
are not over 10,000 feet altitude, the rock
bearing the ore is soft and easily broken,
making labor more effective than in many
places.
W. J. Scoutt and associates have a lease
and bond on considerable property here
and have run a tunnel 2300 feet, a con-
nection with which will be made with
Jumbo No. 2. Then the ground traversed

to consolidate the interests of the Boetcher
electric light plant and the gas plant here
to make extensive additions to both.
Especially will the electrical facilities be
enlarged with the view of supplying
power, as well as light, to the mines
throughout the district. The generators
will be run by steam power, with a grade
of coal which can be delivered at light
cost. It is stated that many of the mine
operators have given assurances of sup-
port, which will doubtless result in in-
creased demands for electrical equipment
in the district. The construction work at
these plants and the operation thereof
will be under the management of G. Wilkes
& Co. of Denver.
Leadville, Aug. 1.
(Special Correspondence). — The Home

OURAY COUNTY.
In Denver it is said that the deal for the
purchase of the Camp Bird mine near
Ouray, from T. F. Walsh, its owner, by
the Venture Co. of London, is closed and
that the mine will be transferred to the
English company this month. T. A.
Rickard's report on the mine, after giving
an account of the condition and extent of
the property included in the transaction,
is alleged to state that upwards of $4,500,-
000 in gold has already been taken from
the veins, principally in development
work. The development of the extensive
property, the report says, the main vein
having been traced for 1J miles on the sur-
face, displays $17,500,000 worth of ore in
sight, and it is further stated that only
about 7% of the vast property has been
thoroughly prospected, while only 5% of
it has been developed. In view of the im-
mense quantity of ore exposed, Mr. Rick-
ard, in his report, regarded $15,000,000 as
a low price for the property. The Ven-
ture Co., it is locally reported, will float the
Camp Bird with a capitalization of $25,000,-
000, the company to be known as " The
Walsh-Camp Bird M. Co., Limited," and
Mr. Walsh to be given about 40% of the
stock in that concern and $10,000,000 cash
for the property, which will be sold on a
basis of $15,000,000. Mr. Walsh will be
the managing director. He was a poor
man in Leadville in early days, now his in-
come from mining investments is about
$80,000 per month. At present he is in
Paris.

SAN MIGUEL COUNTY.
(Special Correspondence). — The Alta, in
Turkey Creek basin, belonging tt> A. J.
Clark and associates, is shipping about
twenty cars per month; being about ten
cars each of crude ore and concentrate.
The ores are sulphides, the principal val-
ues being silver and lead. In the course
of the development carried on during the
past two years ores of the value of $45,000
have been shipped, which has paid for all
work and equipment. The mine is opened
through four tunnels, one above another,
about 200 feet apart, one tunnel being in
1600 feet, another 750 feet, another 500
feet. Most of this tunnel work is on the
vein, which averages probably 2J feet
width of ore, which runs generally about
$50 per ton. In a 220-foot upraise, con-
necting two of the tunnels, the same width
of vein and values of ore are said to have
been demonstrated.

WASHINGTON COUNTY.
(Special Correspondence). — The Pacific,
Idaho & Northern railroad runs regular
trains from Weiser to Cambridge, 40
miles distant. The latter town is near
Salubria. From Cambridge to the copper
mines of the Seven Devils is about 70
miles, which has to be traveled by stage
or private conveyance. Development in
the copper region has not been as rapid as
was anticipated, though results of work
done have been pretty satisfactory in
most cases. A recent shipment from the
Blue Jacket mine of ten carloads of ore ran
42% copper and brought $31,000. There
has been a good deal of talk about es-
tablishing a copper smelter near Cuprum,
but as yet no substantial move has been
made to build one.

Co. has shared the fate of the Richmond,
the old iron contained thorein having been
sold to the Joshua Hendy Machine Works
of San Francisco, and by the use of giant
powder it is being broken into fragments.
It is estimated that there is about sixty
tons of old metal remaining in and about
the building; and when this is removed,
all that will be left of that mammoth plant
is the air compressor and two blowers on
the lower floor and the light machinery
recently used by the Eureka Sampling
Works on the door above. The build-
ings, Supt. McTerney says, will not be
molested. At this time, when the last
vestiges of the two big plants are being
obliterated, some idea of the wealth which
the mines of the two companies have pro-
duced here may be interesting. Of course
the actual values of the ore taken out can
not be even guessed at, but the following
figures taken from the county assessor's
books, and covering the period from April
1, 1873, to April 1, 1900, will give some
idea of the enormous production of the
two properties:
Eureka Consolidated.
Gross value of output. . .$17,480,923 63
Net value 5,206,277 35
Taxes paid 120,333 86
Richmond.
Gross value of output. . .$15,713,975 08
Net value 4,914,169 61
Taxes paid 119,044 27
Thus it will be seen that the gross out-
put of these two mines alone has amounted
to $33,194,898.71; net product, $10,-
210,446.96, according to the books of the
county assessor, and during that period —
from April 1, 1873, to April 1, 1900— they
paid in taxes into, the county treasury
$239,378.13. The mines, of course, are
still being operated, though the output
has been greatly diminished.
LINCOLN COUNTY.
Supt. F. P. Swindler, at the De La Mat-
mine, will treat the 400,000 tons tailings,
average value $2.40, by' releaching.
The handling of tailings along with
crude ores will begin when the automatic
contrivance which is being devised by the
Highland Boy, Utah, smelter is completed.
With this the tailings will be delivered
through a chute connected with the roof
of the plant at an estimated cost of 15 cents
per ton.
WHITE PINE COUNTY.
The Chainman mill is closed for repairs
to the rolls. When operations are re-
sumed it will probably be by the new com-
pany.
Work has begun on the Robust mill at
Ely, to have a capacity of 100 tons daily.

chemical composition necessary to produce
it does not take place at a great depth
there as in Persia, where turquoise in
times past is reported found 800 leet below
the surface. The Tiffany mines produce
best at a depth of 40 to 60 feet. Regular
shipments of gems go forward weekly to
the New York office of the company. Be-
fore shipment the stones in the rough are
composed and assorted into five classes,
the rich blue gem being classed as No. 1
and the lighter stones grading down to the
off-colored light green which together
with its matrix of iron stained lime rock is
usually cut in large size and worked up by
jewelers into sleeve buttons and other or-
naments.
BERNALILLO COUNTY.
The Bland mill is to resume operations
under the management of V. V. Clark.
The Cochiti G. M. Co. is putting out
about 5000 tons per month, yielding a
gross output of about $33,000.
DONA ANA COUNTY.
Gen. Mgr. Geo. C. Hopkins of the New
Mexico Lead Co. in the San Andreas
mountains, 40 miles from Las Cruces, has
a vein assaying 40% uncovered to the
width of 16 feet. It is hauled in wagons
15 miles to the railway station on the
White Oaks road, north of Tularosa :
the freight charge for that distance is
$10 a ton ; on the railway, 90 miles to El
Paso, the freight is $1.50 a ton. Two cars
are shipped daily.

Huntington reports $17,000 paid Vaughn
Bros, by the Northwest Copper Co. —
amount due on the Iron Dyke mine under
the terms of the bond. There is but one
more payment to be made before this
property is transferred to the Nortnwest
Copper Co.
GRANT COUNTY.
Failure to meet the $10,000 due August
1st under the terms of their bond and
lease caused the parties holding an option
on the Magnolia mine, Granite district, to
permit the property to revert to the own-
ers. Coyle, Conde & Jones will start the
mill and work the mine themselves.
JOSEPHINE COUNTY.
The last of the season's clean-ups in the
Sterling hydraulic mine of Ankeny &
Cook gave $14,000 in gold bricks and
$10,000 in coarse gold nuggets, some
of the nuggets weighing nearly five ounces.
The entire season's clean-up will amount
to $100,000.
The Oak Flat placer mines, 700 acres of
undeveloped placer ground, with a 5-mile
ditch and water rights, are sold to Poole
Bros. & Tomlinson of Denver, Colo., for
$8000 and one-third of the capital stock of
the company. The purchasers have or-
ganized the Oak Flat M. & M. Co., capi-
talized at $200,000, and will prepare for
next season's run. The ground is on the
Illinois river and Briggs creek, and con-
sists of an old river channel having a de-
posit of gold-bearing gravel, which shows
fine and coarse gold.
SOUTH DAKOTA.
CUSTER COUNTY.
Near Custer City, from the Tin Crown
mine, several pieces of mica measured
12x22 inches. The Monarch Mica Co. of
Chicago has undertaken large operations
there. They claim to have a process by
which small pieces of mica can be cemented
together under high pressure and look as
well as large ones, and the waste can be
ground up for use in the electrical indus-
tries for insulators. The Standard Oil Co.
also consumes a large quantity in making
axle grease and other lubricators. The
present supply of mica comes from North
Carolina, Canada and India.
An Omaha company has a contract to
ship 1000 tons of hematite iron ore from
the Iron mountain, 8 miles north of Cus-
ter, to the smelters of Omaha, Denver and
Kansas City. The ore in places runs 70%
iron.
LAWRENCE COUNTY.
Manager Wales of the Detroit & Dead-
wood M. & M. Co. is about ready to start
the new cyanide plant, 2 miles west of
Portland.
At Lead the number of men employed
by the mine, mills, railroad, water works,
etc., is 2200. The payroll will average
$200,000 a month. Much of the success of
the Homestake mine is due to the man-
agement of T. J. Grier, an old telegraph
operator, who worked for the Western
Union Co. at Salt Lake and other West-
ern points, and at Deadwood in 1878 as
operator for the Homestake Co. The
Homestake Co. is building an aqueduct 14
miles long from the headwaters of the
Spearfish river to improve the water sup-
ply of Lead City and Deadwood. Six
miles of the ditch will be 30-inch iron
pipe. For the remainder of the distance
the water will be carried through a wooden
flume.
PENNINGTON COUNTY.
Spodumene mineral, which contains
lithia, is found in considerable quantities
near the Etta tin mine, at Hill City, and is
shipped to Germany, where it is manufac-
tured by the chemists. It comes in large
white crystals like stalactite.

pounds for the main building.
SUMMIT COUNTY.
Eastern men have bought the property
of the Constellation M. Co. of Park City
for $115,000, to be paid in two yeats.
The new Silver King aerial ropeway at
Park City will be 7200 feet long; the
cables will be supported by forty iron
towers. Seventy-five buckets will be
strung on the cables to have a guaranteed
capacity of thirty tons an hour, deliver-
ing the ore in the ore bin at the rate of
one bucket every fifty-seven seconds. The
buckets will hold 6£ cubic feet— 1200
pounds.
TOOELE COUNTY.
On the 1st the properties of the Con.
Mercur Gold Mines Co., consisting of the
Mercur and Golden Gate groups at Mer-
cur, passed to the control of a single man-
agement. Shares in the consolidated com-
pany are issued in exchange for those of
the old.
It is understood, says the Tribune, that
the Mercur mill at Manning, from whose
tanks the builders have derived over
$3,000,000 in gold, will be made to handle
the vast mass of tailings that have accu-
mulated about it, while all crude ores will
in a short time be put through the Golden
Gate plant.

Victoria reports that the employes of
the company operating at Blackland
placers on Wreck bay, on the west coast
of Vancouver island, say they have taken
out $80 worth of gold in two hours' work.
Near Sandon in the Slocan, the Ivan-
hoe's new 150-ton mill will be ready for
operation by September 15, is stated by J.
Hickey, manager of the mine.
At Rossland, at the Le Roi, the com-
pressor of 40-drill power is in operation.
The head works of the aerial tramway are
in course of construction above the ore
bunkers at the railroad on Black Bear
flat. The combination shaft is timbered
down to the 800-foot level, where sinking
has been resumed. The mine is shipping
800 tons per day.
Of the present condition of the Miocene
Gravel M. Co.'s property, Harper Camp,
Cariboo, Manager R. H. Campbell says:
"The total outlay to date has been
$150,000. We expect to determine the
value of the property within the next two
or three months. Indications are all that
we could wish; but the channel being so
much larger and deeper than first antici-
pated, it has taken a great deal more
time and money than we at first expected.
However, we do not look upon this as a
bad feature, and we expect to find the
bottom pay stratum correspondingly
larger. If the entire deposit could be
worked by the hydraulic process, it would
be the largest proposition of that kind in
existence; but, unfortunately, one — and
only one — of the principal requisites neces-
sary for hydraulicking is absent, viz., the
dump or outlet for the disposition of the
washed material. The enormous deposit
containing sufficient gold, its susceptibility
for hydraulicking and the abundance of
water at hand make the conditions extra-
ordinarily favorable for hydraulicking if
an outlet could be had. As it is, it must
be a drift mine, if anything."
Ymir reports a fierce forest fire, which
burned the Dundee concentrator. This
concentrator was erected in August, 1898,
at a cost of $16,000; it had a capacity of
fifty tons per day and was connected with
the mine by an aerial tramway 5000 feet
long.
MEXICO.
Chihuahua Enterprise : After three
years of seemingly fruitless effort, the
sinking of a shaft 1300 feet and 1300 feet of
drift work, which represents an expendi-
ture of $100,000 silver, the Santa Eulalia
M. Co. has at last struck it rich in its
mine at Santa Eulalia. The first shipment
of ore (100 tons) is made which will run 50
ounces of silver to the ton and 55% lead.
Thirty tons of ore will be taken out daily,
and the K. C. S. & R. Co. has contracted
to take the entire product of the mine.
The Hearst estate is the chief stockholder
in the Santa Eulalia M. Co.
SOUTH AFRICA.
Cable advices from South Africa regard-
ing the condition of the Johannesburg
mines indicate a resumption of gold pro-
duction before long: that the mines have
suffered little apparent damage, especially
those recently worked. Damages sus-
tained by the other mines have been prin-
cipally confined to the extraction of ore.
Most of the properties will be ready for
resumption when native laborers can be
induced to return to Johannesburg. The
mines are not flooded with water.
Managing a mine in the midst of war's
alarms, with battles going on, is not an ideal
form of mining life. How it affects one
mine manager is illustrated by the follow-
ing from Wm. Naas, manager of the Lan-
caster Gold, one oE the Rand mines, who,
under date of June 15, writes from the
property: "The machinery is in good
order, and also the buildings and cyanide
works, where I had all leaching tanks re-
filled with water. In the case of the Botha's
Reef mine, the hoisting of water was car-
ried on during seventy eight-hour shifts.
From May 1 to May 4 I had only one
winding engine driver; from the 5th to the
21st I had two, and since the 22nd I had
again only one man; 18,914 skips, equal to
6,619,800 gallons of water, were hoisted,
and the water stood on May 31 at 5 feet
below the third level. As regards the
West Battery Reef mine, the Gould
electric pump in the No. 1 shaft works
now only ten hours per night. The water
is kept at 3 feet below the fourth level
station. The water in the company's dam
stands at the 18 feet 9 inches mark, which
is the same as last month. On May 28 I
had thirty trucks of coal at the station
which had arrived during the previous
day and night, and only five hours were
allowed me for off-loading. As a battle
was raging to the south of us, in the direc-
tion of Doornkop, and heavy cannonading
was going on from 9 A. M. to 12 M., my
transport rider refused to work any
longer as he had to bring his oxen in
safety. On the 29th a tremendous can-
nonading commenced at 10:30 A. M. and
lasted, without a minute's interruption,
till 5:30 P. M., when the small-arms
fire also ceased, and I could see from
the headgear the Boer forces retreat and
the British forces take up a position to
the south, and about opposite the French
Rand. Many of my boys got scared and
ran away, but they came back during the
next day or two. I could also engage
other transport riders at a slightly in-
creased price. I had all the coal brought
from the station to the Botha's Nos. 1 and
2 shafts. On May 30, Boer scouts had a
heliograph on the Lancaster West incline
shaft headgear. During the day the Brit-
ish troops entered Roodepoort, and the
railway stopped running in the direction
of Johannesburg, but has continued to
run up to this day (June 15) in the direc-
tion of Potchefstroom. Everything is
very quiet here."
A. Brakhan, who remained in Johannes-
burg throughout the war, writes under
date June 27 stating that in the Botha's
mine there is now about 13,000,000 gallons
of water, and that it will take about six
weeks to unwater the mine, reckoned
from the time when pumping work to the
fullest extent can be started. He also
reckons that the West Battery Reef mine
can be unwatered under six weeks.
THE KLONDIKE.
The Tanana country is the scene of the
latest stampede from Dawson.
G. E. Howard says the principal opera-
tions are confined to Homestake and Faith
creeks, upon each of which he saw men
shovel in from $60 to $100 per day. The
diggings are located 60 miles above the
confluence of the Tanana and MeManus
rivers. "There is little or no grub in the
country, and it is difficult to get in during
the summer season, and in consequence lit-
tle work is possible at the present time.
The mosquitoes are something frightful,
and several instances are reported of men
being driven insane as the result of at-
tacks from the pests. On some of the
claims work had to be abandoned on ac-
count of the mosquitoes."
He met a man who was entirely with-
out grub, excepting an owl which he had
killed, and with no clothing save a badly
torn suit of underwear and a worn pair of
gum boots. His face was literally eaten
by mosquitoes and the man apparently was
out of his mind, being unable to tell his
name or from what part of the country he
hailed. He was given some salt pork,
which he devoured raw.
The Dawson News says: " While the
output in the aggregate was larger than
last year's by nearly 75%, the actual cost
of production was so much greater that
very few mine owners find a balance on the
credit side of their ledgers, and a very
large majority of laymen find themselves
utterly ruined, with hundreds of work-
men whose daily wages remain unpaid as
the result of their winter's toil. The cause
of it lies in the bad laws, excessive taxa-
tion and the defective lay system that has
so long prevailed, affording protection to
no one and permitting of the rankest kind
of wildcat speculations with prospective
mines at the expense largely of the poor
working man. The remedy for the latter
lies in a thorough protection to the work-
ing man, and this can only be given
through a mechanics' alien law that will
make not only the dumps, but the mine
itself, responsible for the wages. The
percentages on which laymen took claims
all of last winter were entirely too small to
warrant any possible profit except on
claims that turned out exceptionally rich.
" Steam thawers have not proven the
bonanza they were expected to be, and
more men have been swamped by them
this last winter by reason of the heavy
cost of running them than can now be fig-
ured up.
"Existing conditions are such that in
order to make mining profitable in this
district a number of important changes
will have to be made. First, the royalty
must be abolished or materially reduced ;
titles to claims must be given ; miners'
licenses must be abolished or brought down
to a nominal, indiscriminate head tax for
every one entering the country — miner or
no miner — and then the country will have
to be thrown open to relocation before
anything like a population can be ex-
pected."

The brakes, clutches and reversing gear are arranged to be operated by compressed air or steam, by means of auxiliary cylinders
which are under full control of the engineer, stationed upon the elevated platform shown, insuring the most rapid work with absolute
safety. Shaft hollow forged steel of ample strength and stiffness to withstand any strains; reciprocating parts of steel and are as light
as consistent with the duty required; cylinders of the "overhung" type, weight being taken by a guide saddle, which admits of free
longitudinal movement, due to expansion, causing no strain on bed plate or foundations; cylinders steam-jacketed, fitted with valves
provided with Corliss releasing gear and hand cut-off, enabling the engines to be run economically with reference to the work to be
performed; bed plates modification of the Porter Allen type, heavy and substantial, with large foundation base and anchor bolts. A
duplicate of this engine has also been furnished the Homestake Mining Company of Dakota.

CROWN GOLD MILLING CO
Manufacturers of the "CROWN" CONCENTRATOR and CROWN
ORE SIZER. A dry process of sizing and concentrating ore, sand or
gravel. Designed to accord fully with the laws of specific gravity,
and especially adapted to refractory ore or localities where there is
no water.
The chief claims for the Crown Concentrator are that it occupies
less floor space and has nearly four times the capacity of any wet
concentrator; that it will concentrate ores containing base and refrac-
tory metals that ordinarily slime and carry off values; that it effects
a saving of values far above the ordinary methods of concentration.

XHE GRIFFIN
THREE ROLLER
ORE 7VVILL.
Tho Griffin Three Roller Ore Mill is a simp.y constructed Mill, suitable for working all kinds of ores that
require uniformly fine crushing by tho wet process. This Mill is a modification of the well-known Chilian
Mill, but tho rollers run upon a crushing- ring or die, which is inclined inwardly at an angle of about .'10 degrees,
tho rollers themselves also boing- inclined to tho centra] shaft of tho Mill, thus utilizing tho centrifugal force,
as well as tho weight of tho rollers themselves as tt crushing agent. Tho Griffin Three Roller Ore Mill is there-
fore a Mill of great strength, and has fow wearing parts. Wo construct these Mills with extreme care, using
only the bost of raw materials, which are most carefully worked by men who are specialists as mill builders.
We sell the Griffin Ore Mill on its dotorminod merits, and will gladly supply full information regarding it to
any one.

who says there's nothing equal to the Wilfley, and I am trying to
convince him that old man Woodbury over in California makes
S the finest table in the world." " No, sir," said his comrade, "you're

THE IMPROVED BARTLETT CONCENTRATING TABLE.
The BARTLETT CONCENTRATING TABLE has been GREATLY IMPROVED recently by the substitution of iron
in place of wood wherever possible. It is now built with SOLID IRON TOP, PLANED TO A TRUE SURFACE AND
POLISHED ; all parts are made by template and EACH PART BEING INTERCHANGEABLE. As now constructed,
the table has no special wearing parts and will last for many years. It has a CAPACITY OF FROM FIFTEEN TO
FORTY-FIVE TONS IN TWENTY-FOUR HOURS, according to the class of ore worked. It is the only table in the
world which will take the place of jigs and do away with all costly and complicated machinery.
It is Especially Designed for Separating Zinc from Lead.

THE BROWNELL "PATENT LIP" FLANGE FRUE VANNER BELTS.
It has taken years of ceaseless testing and experimenting to produce the superior belt which
we now offer, with elastic flanges and pliable body reinforced with specially woven duck. Every
belt is manufactured by experienced workmen, and carefully tested on machines especially built
for that purpose; consequently we are to-day manufacturing the best belts that mechanical in-
genuity, combined with honesty of construction, can possibly produce.

the latter. They will certainly wear much longer, as oracking now seems out of the question. Any one purchasing the Frue vanning machine
should see that it is equipped with the Patent Lip flange belt. Very truly yours, ROANOKE MINING COMPANY.

Lead Ore Imports.
In an extended editorial discussion of
"Lead Tariff, Prices and Supply" in
the issue of July 21st, regarding the
importation of Mexican lead ores, the
statement was made that, "the chair-
man of the Bureau of Statistics for the
U. S. Treasury Department in 1898
made official report that 21,000,0(10
pounds of lead had been entered that
could not be accounted for.''
The accuracy of this statement has
been <|iiestioned, and the fact has been
denied. The chief of the Bureau of
Statistics in Washington furnishes the
following statement :
Pounds.
Lead in warehouses beginning
of fiscal year 1896 21,000,000
Imported in bond 187,522,267
Total 208,522,267
Ketained for home consumption. 109,000, 000
Exported 64,888,000
In warehouse at end of 1896 . . . 13,634,267
Total 187,522,267
Short 21,000,000
This establishes the truth of the state-
ment in the issue of July 21st. Each
statement made in that article is sus-
ceptible of similar substantiation.
Official U. S. Treasury statistics show
that in the year 1896 were imported
from Mexico 231,747,741 pounds silver-
lead ore, of the value of $6,153,894; this
contained 29,207 tons of lead. During
Ore Bins in Shaft, Empire Mine, Grass Valley, Nevada Co., Cal. (See page 184.)

The 2100-Foot Station, Empire Mine, Grass Valley, Nevada Co., Cal. (See page 184.)
the same year British Columbia shipped
into the United States 63,785, 106 pounds
lead ore. It is true that less than 183,-
000,000 pounds lead ore were imported in
1890, but lead in ores was duty free prior
to Oct. 5th of that year. Following is
further official U. S. Treasury report of
the quantity of ore imported in each of
the three succeeding years and the lead
contained therein :
Pounds Lead
of Ore. Contained.
1891.... 239,086,809 40,289,808
1892.... 317,599,298 50,382,297
1893.... 406, 209, 367 59,426,588
These figures show that
silver-lead ores do not
than enough lead to
selves successfully, and that the pres-
ent duty on lead in ore is not pro-
hibitory.
Electric railways in most large
cities develop newer and suburban sec-
tions at the expense of older settled
districts ; more especially is this the
case in that part of a city which is too
near the business center to be valu-
able for residence purposes, and, at
the same time, too remote from the
business centers to be of value for
business purposes. Such property is
the worst kind to own as an invest-
ment proposition, and the most dan-
gerous upon which to loan money,
as there is no guide in establishing its
market value.

' ' Next winter will be the wettest of any for
twenty years in California," is the prophecy of Cali-
fornia coasting captains, which will not be objected to
by California miners.
And now it is seriously proposed by well meaning
but mistaken Canadian legislators to reopen the whole
vexed question of mining law in that province. Like
all other sections, all that the miners of British Co-
lumbia need or ask is just to be let alone. It would
seem from past experience that Canadian legislators
should know this. Their action in 1899 created tur-
moil and entailed loss. The only result of the pro-
posed Canadian legislation would be to again check
the progress of the mining industry throughout that
whole area.
It used to be said that "trade follows the flag,"
and that belief still exists, but statistics do not sub-
stantiate it. There is no sentiment about trade, its
function being to supply human wants that it some-
times helps to create. What a great many consume
constantly they will buy where they can get it the
cheapest, asking and caring little where the supply
originated. Patriotism is not dominant in buying
and selling. Taste and fashion are more potent.
Geographical situation, the cost of the product laid
down, are prime factors also. Trade will, however,
" follow the flag " that shelters it. If the flag se-
cures peace and rightful law to the trader, and if its
folds carry assurance of protection, trade will follow
wherever it flies.
Lofty disregard of petty detail is not characteris-
tic of the successful man. It is not he who makes
the general suggestion or to whom occurs the ab-
stract idea that has contributed most to mining or
scientific progress, but the man who patiently
wrought out the idea into practical shape. Like
other crude material, it is the workmanship, the de-
tail, put upon an idea that makes it of value. Prob-
ably to many had occurred the idea that some kind of
vegetable fiber would well serve in the incandescent
electric light, but it was the patient, steady experi-
ments of Edison and his expenditure of thousands of
dollars that produced the practical result. To many
minds had doubtless occurred the idea of some swift
process of effectually converting iron into steel by
blowers, but Bessemer and his years of research and
expensive experiment constituted the necessary de-
tail that made it commercially profitable.
Permanence in Depth.
In the last paragraph of the third and concluding
part of Manager Starr's excellent paper on the
Empire mine, Grass Valley, Cal., on page 185, oc-
curs a suggestion deserving of editorial endorsement
and observance by many. Speaking of the mine as a
permanent, profitable proposition, in the last sentence
in his article, he refers to the desirability that the
' ' shareholders will be willing to receive a reasonable
interest return on their capital and will endeavor
persistently to open up reserves in excess of extrac-
tion. "
The non-observance of such suggestion, the clamor
for constant dividends, and the hesitancy marked by
their being passed, have ofttimes proved fatal to suc-
cessful continuance of work that would have made a
good, permanent mine out of a promising property
— this without any individual reference, but as a gen-
eral observation. It is to be noted that in most
ore shoots there are frequent local irregularities, as
occurred in the Ophir vein, in the mine of which Mr.
Starr so instructively writes ; and such local irregu-
larities make it difficult to judge without extensive
exploration whether the end of any certain ore body
has been reached.
Where there exists among stockholders a constant
demand for dividends, an insufficient understanding
of the true economy of mining ; where thereby has
resulted the habit of immediate distribution of all of
the mine's profits as dividends ; where reserve funds
for necessary development or exploratory work are
thus unavailable, splitting or pinching or local im-
poverishment in any level at any depth has too often
been the occasion of closing down a good mine. Lack
of nerve, a discounting of the future, and limited un-
derstanding of the requirements of the situation on
the part of those who hold the purse strings, are
among the causes of idle and deserted mining camps
in many a section where, under better understand-
ing, should be constant and profitable extraction of
ore.
The truth of this is manifest by simply referring to
the best gold quartz producers in California to-day ;
and this applies to other States as well. A score of
mines whose names will occur to California miners
attest the fact that a pay shoot continues far below
the depth at which at one time many of such mines
had been developed.
In this regard it is to be noted that while many
smaller veins carry only one ore shoot, in larger fis-
sures there are generally several of them, and there
is a constant probability that in such veins thorough
exploration laterally or in depth will develop new
bodies of ore, if the one on which exploitation has
been carried on is found to pinch out. Of course, the
first question naturally arising is as to whether with
increased depth and cost of mining it would be good
business or of likely profit to carry on necessary
dead work. That such necessary dead work has
been resultant in the making of many a great mine
should go far toward taking the question out of the
domain of theory and placing it among established
fact. In each individual case this question of such
interest to mine owners must naturally be decided
by the record of the mine and the character of the
fissure.
In an extended discussion of this subject of per-
manence in depth in California gold mines, W. Lind-
gren in a monograph on the quartz veins of Nevada
Co., Cal., published by the U. S. Geological Survey,
discussing this matter, says:
It is generally conceded now that Assures are,
comparatively speaking, surface phenomena, and
that below a certain depth, where plasticity and
flow of rocks under pressure come into play, open
spaces can not exist. This limit Prof. Heim, for in-
stance, places at 16,000 feet, while Prof. Van Hise,
basing his consideration on the strength of rocks,
arrives at 33;000 feet as the maximum limit for hard
rocks in which fissures can exist. Even the lowest
of these estimates far exceeds the depth of practica-
ble mining. But it is not likely that all Assures con-
tinue until that limit. On a small scale the discon-
tinuance of fissures may be observed in extensive
sheeted outcrops. It is also an incontestible fact
that many small veins close up in depth, while others
continue unchanged. In considering the probable per-
manency of a given vein, its general character must
be taken into consideration. Continuous well-defined
outcrops and large bodies of quartz are in general
good indications of the maintenance in depth, as is
also any evidence of strong faulting and movement.
Some quite extensive veins, though, have relatively
short outcrops. Thus, the Eureka-Idaho practically
shows croppings only for a distance of 2000 feet, but
within that distance they are very prominent. Those
of the North Star are less than 2000 feet long. Prom
the developments to the east along the Omaha sys-
tem it is pretty certain that the vein does not con-
tinue far across in that direction. A fissure which
can be definitely proved to extend only a short dis-
tance will in all probability be found to be corre-
spondingly limited in depth. In regard to probable
permanency of the vein in depth, the Ural and Merri-
fleld, along which extensive faulting has taken place,
stand first in the districts.
In scrutinizing the scant statistics of the produc-
tion, in tons and value, of the Grass Valley district,
it can not be denied that they show on the whole a
distinct increase. There is also a distinct decrease
in the average value of the ore. It is not safe, how-
ever, to draw too far-reaching conclusions from these
data, because there are many factors involved: The
cost of treatment and mining has decreased greatly
by reason of the modern methods introduced, and
more low-grade ores are now milled than formerly;
nor are there any rich surface ores left to swell the
grade.
Leaving the difficult question of deep mining out of
consideration, there are, however, in both districts a
large number of veins which have been only slightly
developed, but which with improved methods may be
converted into paying mines. The development of
these will probably maintain the production of the
district for many years in the future, even if no new
ore bodies are discovered in the old mines.
It can be confidently stated that there is no grad-
ual diminution of the tenor of the ore in the pay
shoots below the zone of surface decomposition.
Within the same shoot there may be many and great
variations of the tenor, but there is certainly no
gradual decrease of it from the surface down. This
important fact has been previously stated by those
conversant with the veins. The statements to the
contrary are due to imperfect acquaintance with the
facts and generalization from insufficient premises.
Mining Combinations.
The tendency to "trusts," combinations and com-
bines, so manifest in all departments of the indus-
trials, is daily more apparent in the mining world.
Prom Michigan, Colorado, Utah, California, Nevada
and Washington come reports of combinations of
adjoining mining properties in the interest of econ-
omy, it being usually figured that it is cheaper for two
or more contiguous mine properties to consolidate in-
terests and dispense with a double set of managers and
office force, besides doing away with the ever present
possibility of mine litigation. Of course, it is manifest
that in the very nature of things the ordinarily
accepted elements of "trust" methods do not nor
need not enter into any combination of gold mining
properties, as that form of industry is exempt from
any need of manipulation of price or supply, the
product being of fixed value and universal and un-
limited demand.
The latest report of metal mine combination is from
California, where quicksilver producing properties in
Colusa and Lake counties are reported to be consoli-
dated into one organization, formed under the laws
of New Jersey.
California has a practical monopoly of quicksilver
production on this continent, and the conditions
would seem more suggestive of all the possibilities of
a " trust " than ordinarily obtains.
In this regard is to be observed the current con-
flicting conditions of the quicksilver industry. Bos-
ton, where several of California's quicksilver mines
are owned and managed, wires this week :
Some fear is felt in the trade that the world's pro-
duction of quicksilver is likely to prove unequal to
the growing demand. The total supply in 1899 was
about 95,000 flasks from Spain, Italy, Austria and
California. This was less than for quite a number of
years, with an exception of two. The production of
the cinnabar mines of California, the only large pro-
ducers upon the American continent, has declined
from 79,000 flasks in 1888 to only 28,100 in 1899. The
principal mines of Spain and Austria, which have
been producing for nearly 2000 years, are the only
other producers of importance, except Russia, pro-
ducing 8700 flasks last year, none of which came out
of that country. Spain produced 39,340 flasks in
1899 and Austria only 15,000.
Such statements in the form of an Associated Press
report usually precede a rise in the price of the arti-
cle so discussed. But in this case there is a depreci-
ation in current quotations, which this week, locally,
are $48@48.50 per flask, domestic, and " about $45"
for export. London advices also report a decline in
price there.

By actual count 247 notices of this paper were observed
in different publications in the period from June 15 to
Aug. 15, 1900, that is, during the last sixty days. And
of these every one was complimentary. This is believed
to be worthy of notice.
Verdigris can be removed from copper plates by
thoroughly scrubbing them with very fine sand and
water, using a gunny sack or scrubbing brush. After
the sand is washed oil, scrub with a solution of one part
oil of vitriol and four parts water.
Iron can bo distinguished from steel by the use of a
drop of either dilute nitric or sulphuric acid. If the sur-
face remain unaltered, or nearly so, when so touched, the
metal is iron; in the case of steel a black mark will be
left, showing the liberation of carbon.
The grain side of a leather belt should be run next to

rubbed on tho belt and pulley ought to stop the belt
from slipping.
The Supreme Court of California has recently ruled
that a technical objection to the manner of fixing monu-
ments to mining claims is not sufficient to depose the
original locators, if they have otherwise acted in good
faith. This decision was made in a case from San Ber-
nardino county.
For spelter — metallic zinc — ores carrying 60% at least
are requisite for profitable result, and the less iron or
lead the ore carries the better. The ore is not susceptible
to smelting, but requires careful roasting. Hence the
cost of extraction limits its commercial possibilities in
Colorado and elsewhere.
Lead miners are in no way liable to lead poisoning.
The danger only occurs when the ores are smelted. It
then results entirely from the formation of lead dust and
of volatile lead fumos. In order to obviate the danger it
is necessary to prevent lead fumes from being formed, or
to conduct them away as rapidly as possible.
Illuminating gas burning 5 feet per hour in an open
burner has about 18 candle power. In San Francisco
such gas costs about $1.50 per M cubic feet. On that
basis electric lighting current would cost about 11 j cents
per kilowatt hour. California electric companies uni-
formly charge flat rates, others selling by meter measure-
ment.
Not all the " fakes " are found in the lying prospec-
tuses of Copper Gongs and Golden Crowns. Of equally
spurious character is the " capitalist " in alleged search
of "a good going mine," or " a thoroughly developed
property, " who expects the owner of the property to
prove its worth at his (the owner's) expense, and then let
the "capitalist " have it at the price of an undeveloped
prospect. And, sometimes, when one of those "capital-
ists " ami tbe author of a meretricious mine prospi
get together, each trying to oheal ir, there is
rabie undisguised hilarity on tbe back seats.

Theoretically a pipe 10,000 feet long, 12 Inches
diameter, will disoharge 4.26 cubic feet per second under
a bead of 100 feet, in practice the figure would require
modification, Under the conditions stated tbe mean
velocity would be 5.41 feet per second. The area in a
square foot of pipe is the same as tho contents of 1 foot
in length of tho pipe in cubic feet.
San Francisco's normal annual rainfall is 2.1.4 inches.
Fluctuations have occurred between a rainfall of 7.4
inches in IS50 51 and 49.2 inches in 1861-62. Tho varia-
tions in tho winter rainfall are due to the changes in the
positions of tho lines upon and along which tho areas of
low pressure originate and niovo in their course from the
North Pacific ocean into the interior of the continent.
There is no limit to tho distanco compressed air can

less all the factors in the problem are supplied. In gen-
eral working results can be socured with a distance of 4
milos between compressor and drills. By keeping out
inch-pipe and elbows the efficiency of a pipe line may be
increased .
The use of ovon a weak solution of cyanide in cleaning
amalgam plates is not favored by many millmen, who
use dilute nitric acid, salt and water or scalding hot
water, though the last sweating process is not considered
good except at long intervals, or in shutting down the
mill indefinitely. A page article in the issue of July 1,
1899, gives some practical points on this subject of clean-
ing plates.
TWO per cent would represent, approximately, the
average content of silicon in. the pig iron produced in
American furnaces. Under certain conditions, the effect
of manganese added to molten metal is to cause nearly
40% of the combined carbon in pig iron low in silicon to
revert to the graphitic form. The strength of test bars
so treated is increased 30%, the depth of chill decreased
20% and the shrinkage decreased about as much.
A locator of a mining claim can let it alone, do no
work on it for five or six years, and if every one else lets
the claim alone, he can get a patent by doing work or
improvements to the amount of $500. But he takes
chances right along during the period he fails to comply
with legal requirement. His title is good as long as no
one thinks the claim worth jumping. The $100 annual
work is not "to keep the title alive," but to prevent it
from lapsing.
About as large a storage battery as any in the coun-
try is that of the Chicago Edison Co., 139 Adams street.
It consists of 166 cells — 60 end cells— 83 on each side of a
three- wire system. Each cell contains 87 plates 15Jx32
inches. The tanks are of 2-ineh ash, lined with 5-pound
sheet lead; each tank is 21 J inches wide, 79JJ inches long,
and 43J inches high, and weighs 6200 pounds. The en-
tire battery, exclusive of conductors, weighs 1,029,200
pounds. It has a capacity of 22,400 ampere hours at an
eight-hour rate.
Water can absorb about one-twentieth of its volume
of air, and all water which has not been boiled contains
almost as much air as it can absorb. One pound of water
at about 70° F. occupies a volume of 0.016 cubic feet, or
2.3 cubic inches, and one-twentieth of this is 0.115 cubic
inch. That is, one pound of water at ordinary tempera-
ture contains about 0.115 cubic inch of air. When water
is converted into steam the air which it contained passes
off with the steam, and occupies a volume which depends
upon the pressure and the temperature.

Such words as "about" and "more or less " are often
inserted in a contract of sale in order to relieve the seller
from liability in cases where he has used his best efforts
to deliver the amount called for. In any case in which
the seller, under such a contract, has tried, to make
delivery as stipulated, the courts will allow him a fair
margin to cover unavoidable mistakes, and as much as
10% has in some special cases been held to be such fair
margin. But the seller is never allowed to take advant-
age of this clause for the purpose of deliberately com-
pelling the buyers to accept more or less than he has
contracted for. The Supreme Court of the United States,
for example, has held that the words " about, "" more
or less," and the like, used in such cases, are effective
"only for the purpose of providing against accidental
variations arising from slight and unimportant excesses
or deficiencies in number, measure or weight." (6 Otto,
168.) ln everj case it Is the seller's duty to weigh or
measure out, and deliver, as nearly as possible, the <
amount called for by his contract. In doing so be is
protected by the terms of his contract against anj
liability arising from tbe fact that it is impossible to
r precisely the amount for which tbe agree-
ment calls. But a seller cannot claim protection from
the Baving clause of the contract until he has tried in
good faith to fulfill its main stipulation.
ALL substances are either attracted or repelled in
some degree when in tho field of a strong electro-magnet,
if attracted, they aro said to bo paramagnetic; if re-
pelled, they are diamagnotic. If a rod of any substance
is suspended by a liber so as to sw ing freely horizontal!]
between tho vertical poles of an electro-magnet mag-
netic induction takes place, and as the lines of force be-
tween tho poles are essentially horizontal tbo effect of
tho pull or thrust upon rotation is groatost for the par-
ticles farthest from tho axis of rotation. If paramag-
netic, therefore, tho effect is to pull the rod into a
longitudinal or axial position, with its ends as near the
poles of the magnut as possible; and if diamagnotic, tho
rod is pushed into a transverse or equatorial position,
with its ends as far from the magnotic polos as possible.
FOR the fiscal year ending Juno 30, 1900, tho exports
of copper were 333,340,725 pounds, or 148,813 tons, valued
at $55,772,166, as compared with 254,987,164 pounds in
1899, or 113,833 tons, valued at $34,476,343. The manu-
factures of copper exported in 1900 were valued at$2,079,-
541, as compared with $1,507,186 in 1899. The exports of
sulphate of copper for the fiscal year ending June 30,
1900, were 47,790,765 pounds, valued at $2,120,745, as com-
pared with 27,474,801 pounds, valued at $1,173,186 in 1899.
The export trade in sulphate of copper was not separately
reported until 1898, in which year was exported 14,730,-
373 pounds, valued at $475,707. The total value of ex-
ports of copper, not including ore, and manufactures
thereof, including sulphate of copper, in the fiscal year
1900, was $59,972,452; that of $37,156,715 in 1899 was the
next largest.
To hold the possessory title to a mining location
not less than $100 worth of labor must bo performed or
improvements made thereon annually until entry shall
have been made. The first annual expenditure becomes
due and must bo performed during the calendar year
succeeding that in which the location was mado. Ex-
penditure made or labor performed prior to the first day
of January succeeding the date of location will not be
considered a part of or applied upon the first annual ex-
penditure required by law. Failure to make the expendi-
ture or perform the labor required upon a location will
subject a claim to relocation, unless the original locator,
his heirs, assigns or legal representatives have resumed
work after such failure and before relocation. Annual
expenditure is not required subject to entry, the date of
issuing the patent certificate being the date contem-
plated by statute.
In last week's Issue in response to a question as to how
to best get the gold or amalgam off old copper plates, a
leading assayer furnished "Concentrates " with suitable
answer. Upon its appearance, another experienced
authority says that a good way to free copper plates
from gold is to put them over a charcoal fire and slowly
evaporate the quicksilver. The plates should be cooled
gradually, then rubbed with muriatic acid, put in a damp
place over night, then rubbed with a solution of sal
ammoniac and saltpeter, and slowly heated over a thin
.•ed fire, but not allowed to get redhot. When the gold
scale blisters the plates should be taken from the fire and
the gold scraped off. Where the gold has not blistered it
should be treated with the solution and again fired. Col-
lect the gold scales In an earthen dish, cover with nitric
acid till the copper is dissolved, when the gold can be
smelted ; after melting, corrosive sublimate should be
used in the crucible till a blue flame ceases to burn.
The Quintera lode, Sonora, Mexico, is a silver ore
containing galena, 11% to 16% zinc, 8% to 11% copper,
and arsenical and antimonial sulphides. The yield in sil-
ver is 100 ounces per ton; the gangue is quartz. The
stamped ore is roasted in reverberatory furnaces with
four-graded hearths at a low temperature. Ores con-
taining blende require three hours, other ores, two hours,
at each hearth. The addition of 4% to 8% of salt is
made at the last hearth two hours before discharge. The
chloridized ore is discharged on a cooling floor in heaps,
and is then charged into vats with sand filters of a foot
in thickness. The lixiviation with water lasts fifteen to
twenty-four hours, the chlorides and sulphates of copper,
zinc and iron being dissolved. Lixiviation with double
hyposulphite of calcium and sodium follows, the best
strength of solution being found to be 0.55% to 0.66%.
The silver is precipitated by a calcium polysulphite solu-
tion. The sulphides are collected twice a week, dried,
roasted at low temperatures in a reverberatory furnace
and incorporated in the cupellation with litharge. For
cementation of the copper in the leaching waters, copper
mattes from lead smelting have been used with success.
Very poor silver ores are concentrated, agglomerated
with clay and 10% of charcoal, and smelted with ores of
a superior grade in a water-jacket furnace, the chief dif-
ficulty being caused by the high percentage of zinc,
arsenic and antimony. The copper matte is concentrated
to 40% by resmelting. The slags carry 1.3 ounce of silver
per ton. The cost of 1 ounce fine silver at last accounts
was stated to be divided as follows: Mining 36.0%,
milling 26.4%, administration 6.9%, profit 30.7%.

George W. Starr, Resident Manager.
The main working shaft is sunk on the Ophir or
Empire ledge, with miles of drives extending along
the vein at different levels. The Rich Hill and other
veins, lying in the hanging, will be worked by cross-
cuts run from the 800, 1400 level, etc. ; thus many
drives on the Ophir vein may have a series of parallel
drives on different veins.
Underground development work is carried on with
3i-inch air drills, Rand and Ingersoll-Sargent. The
air is supplied (pressure at drill 80 pounds) by a duplex
compressor, cylinders 16x24 inches stroke, designed
and built by the Risdon Iron & Locomotive Works;
two inch Baby drills are used for raises and some
stoping. The average cost per foot for 5x7 foot
drives being: Materials, $1.16; miners, $2.87; power,
the course of the vein, with other shoots horizontally
therefrom and parallel thereto on different veins, but
without any regular trend or, if any, opposite to the
trend of the nearest crossing. The values in the
quartz consist of free gold, which is easily amalga-
mated, and from %\% to 3i% of sulphurets that run
from $60 to $200 per ton. The quartz at times car-
ries so much free gold as to be " specimen rock," and
probably a percentage of this rock is lost by theft.
Notwithstanding great care in surface draining
and a very complete system of drain tunnels, the
mine makes considerable water. In winter 450 gal-
lons per minute are pumped from the 1100 station to
drain tunnel and 250 gallons per minute from the
2200 station to 1100. The Cornish pumping system
is used and will this year be supplemented with an
hydraulic pump at the 1100 station, capable of lifting
600 gallons per minute to the drain tunnel. This
pump will be operated with water under a head of
820 feet. In a recent test it was found that our Cor-
nish pump system gave a realized efficiency of 52% of
the original power (water) applied to Pelton wheels
under a head of 420 feet.
After being mined the ore runs or is shoveled or

maintenance, hoisting, etc., $1.73; total per foot,
$5.76. From 1892 to 1898 shaft was sunk 110 feet.
In 1899 shaft was sunk 205 feet. This year it is ex-
pected we will sink 400 feet, making a total depth on
the incline of 3080 feet, All costs of shaft sinking in
1899 amounted to $16.87 per foot; the ground, how-
ever, was very favorable.
Levels were formerly run giving about 100 feet of
backs, but owing to their extent (the 2100 level is
now 3900 feet long, extending 2500 feet north and
1400 feet south of the shaft), the levels will be kept
far enough apart to give 250 feet or more of backs.
The veins have general northerly and southerly direc-
tion, with an average dip of 30° to the west; they
continue without disturbance from the surface rock
formation down into the deepest and last intrusive
rock formation of the Grass Valley district and can
be relied upon to extend to great depth. They vary
in width from a mere seam to 1, 2 or 3 feet, and have
many branches that, when found, must be drifted
upon before it can be determined which one consti-
tutes the main vein. All quartz in the vein is not
pay ore, some of it not being worth even a dollar per
ton. The bonanza value occurs in shoots or bunches,
which in my opinion form laterally (in zones) along
trammed through intermediate drives into large bins
provided with gates. From these bins it runs into
the ore train. This train consists of six cars, each
holding 1200 pounds, drawn by a mule, the grade of
the drives being I of 1% in favor of the load. The
cars used underground are the Rand " TJ " type, side
tipping, made entirely of iron. The ore is thus
hauled and dumped into bins at the shaft, from which
the skips, each holding 3500 pounds, are loaded. The
shaft is 16x7 feet, divided into three compartments
consisting of two haulways, ladderway and pumpway;
gauge of track, 30 inches, laid with thirty-pound
steel rails. The shaft is lighted with incandescent
electric lights placed 50 feet apart. Each hauling
compartment is provided with electric return signal
bells and a telephone system communicates to the
principal stations from the hoist and machine shop.
All wires are in conduit.
At a speed of 1000 feet per minute the skips are
hoisted and automatically dumped on grizzlies at the
top of the headgear, the finer particles falling direct
into the lower ore bins, the coarse falling into a sep-
arate bin holding 150 tons. In front and just below
this bin is a No. 5 Gates crusher, which, when run-
ning, is fed with a continuous stream of quartz by
opening the gates leading from the bin. The waste
rock is loaded into the skips from a compartment of
the shaft bins, hoisted and automatically dumped into
a bin holding 150 tons, situated below the upper ore
bin, from which it is trammed, in side-discharge cars,
to the circular waste dump.
The hoisting works consist of a headgear 94 feet
high, supporting ore and waste bins (lined with 30-
pound "T" rails), crusher, etc. Foundations are six
cement piers, 11 feet deep, 4J-foot base and 2£ feet
on top, on which rest main sills, 18x24 inches Oregon
pine, main framework 18x20, Oregon pine. The
hoist was designed by Connors & Grant, built by the
Union Iron Works, and consists of two 6-foot reels,
with 8-foot friction bands driven by paper frictions
24 inches diameter, 13-inch face, operated by two 10-
foot Pelton wheels, each with three nozzles controlled
by hydraulic gates. Capacity of hoist at present
depth is 750 tons in twenty-four hours, it being de-
signed for future requirements and capable of hoist-
ing from a depth of 5000 feet at a speed of 1000 feet
per minute. Water under a pressure of 420 feet is
used for hoisting, pumping and for compressor, with
steam and necessary engines in reserve in case of
failure of supply.
The pump, compressor and boiler house is situated
back of the collar of the shaft and extends under the
incline of the headgear. Thirty feet in front of the
collar of the shaft is a building 30 feet by 120 feet, in
which are blacksmith, machine and carpenter shops,
with all necessary lathes, planers, drills, presses,
etc. Over the shops are two changing rooms for
underground men, one for each shift, bosses' room,
supply and timekeepers' room. The changing rooms
are heated with hot water passing through pipes, on
which clothes are dried.
From the crusher the ore passes into the lower ore
bins, which hold 150 tons, provided with bottom dis-
charge doors, from which it is trammed in side-dis-
charge cars, each holding one ton, to the ore bins in
the mill. These bins hold 600 tons. Here it passes
through the 40-stamp mill (run by electric power,
with water power in reserve), over vanners and
finally into a Gates slime plant. Satisfactory assays
of the ore before it enters the mortars are not as yet
obtainable. The pulp is assayed when it leaves the
plates, when it enters the slime plant, and when it
finally passes through the tailings automatic sampler,
after leaving the slime plant.
The percentage of recovery is as follows :
By battery amalgamation 518
Outside plates 231
Vanners 147
Settling tanks for overflow, cleanup escapes, float,
sulphurets, etc 012
Slime plant 038
Total extraction 946
The above is the average for eighteen months. The
following percentage averages are for three years :
Per cent of amalgam to 1 ounce of quicksilver fed in
mortar, 2.98 ounces ; per cent of gold to 1 ounce of
quicksilver fed in mortar, 1.41 ounces ; milling costs
per ton ore crushed, $0.4924.
The mill is of the usual type, Homestake pattern
mortars, stamps 850 pounds, 7-inch drop, speed 100,
order of drop 1-5-2-4-3. The character of the ore
requires fine crushing ; 40-mesh screens are used.
Run of plates 4x17 feet, 1$ inches to the foot grade.
The cleanup pan consists of a large cast iron bowl,
revolving twenty times per minute, set on an angle
of 45°.
Cannon balls are placed in the bowl and re-
volve in an opposite direction to the pan, grinding
and cleaning thoroughly all amalgam, headings, mag-
net iron or anything from the mill requiring grinding.
A continuous overflow of water washes out all waste
material, leaving a product which is easily cleaned
up.
From December 31, 1878, to January 1, 1899, ore
mined and milled 218,241 tons, at a total expense of
$11.15 per ton.
From December 31, 1898, to January 1, 1900, the
following results were obtained : Ore mined, 24,682
tons ; ore milled, 24,707 tons ; development work,
5665 feet ; total expense per ton, $7.09. For six
months of 1900 : Ore mined, 14,784 tons ; ore milled,
14,280 tons ; development work, 4310 feet ; total ex-
pense per ton, $5.97.
With improvements now under way at the mill
2700 to 3000 tons of ore will be milled monthly, and
development work increased at least 800 feet per
month.
The average width of the ledge in the numerous
stopes is at present less than 2 feet. By stoping in
an average width of 2 feet, increasing tonnage
milled and a hoped for reduction in the cost of power,
I expect to bring all costs under $5 per ton, including
800 feet of development work per month.
The appearance of the surface of this property
has been the subject of much comment. The collar of
the shaft is arched with granite. All buildings of
the plant are enclosed with No. 26 galvanized iron
and built on rock foundation, no timber rests within
4 feet of the ground. The floors of the mill are
asphalt, laid on a concrete foundation.
The office is built of stone and contains, besides the
usual general and private offices, map, drafting, as-
say, retort and melting rooms. A portion of the

basement is used for a store room, from which sup-
plies are issued.
Adjoining the plant is a natural park, beautiful
with lawns, shrubbery and an artificial lake. Cot- !
tages have been built tor the officials of the company
that are suggestive of Burlingame or Tuxedo. The
plant and park are surrounded by a high stone wall.
The plant is protected from fire by numerous mon-
itors.
What appears to some as an extravagance is a re-
munerative investment. The lake is a reservoir that
receives the water used for power, from whence it
flows to be used at the North Star mines and Allison
Ranch mine.
At the collar of the shaft repairs are no longer
necessary. In the mill and buildings there are no
floors to wear out or timbers to decay; repairs are
reduced to a minimum, maintenance and insurance
accounts are small, and, above all, the influence of
the surroundings invite a high class of labor, and sys-
tem, order and neatness become a matter of course,
A visit to the property by the officials and share-
holders is no longer irksome, but more in the nature
of a pleasure trip, and personal interest by those
financially interested is a spur to the administration
of any enterprise.
The oldest continuously worked gold mine in the
United States after an active life of nearly fifty
vears is thus passing from its infancy, its growth no
longer checked by lack of means of development.
As long as its shareholders will be content to receive
a reasonable interest return on their capital and will
endeavor persistently to open up reserves in excess
of extraction, their property will remain a model for
California mining, and a monument when mining In
California is no more.
Silver Smelting in Mexico.
NUMBER IV.
The fuel used is Laredo coal. The pots hold 425
bars of furnace bullion, at 96 pounds, and are
supposed to turn out twenty tons of improved bul-
lion ; but they do not do it without refilling
after skimming. The bullion is syphoned off into
moulds, arranged in a semicircle around the pots,
an arrangement borrowed from desilverizing estab-
lishments. The object of remelting the furnace
bullion is to get the copper out of it and utilize it in
the blast furnace, and also to be obtain a correct
sample which is taken out of the swivel pot of the
syphon. The continuous recharging of the dross ob-
tained from the pots into the blast furnaces is an
absurdity, as in the course of time the furnace bullion
becomes so deteriorated that the syphon tap refuses
to work. The plan of smelter No. 2 to a liquate its
furnace bullion and put the dross through a separate
furnace is decidedly preferable.
There are also two specially constructed platform
scales in this building on which the bullion is weighed
and reweighed. Tracks of 30-inch gauge connect the
blast furnaces with the pots, the weighing floor, and
the railway cars to be loaded with the bullion. An-
other track connects the dross dump with the ore
shed.
In a place between the refinery and the calciners
there is a covered kiln for baking flue dust bricks,
which is arranged for burning Laredo coal. Directly
behind the blast furnace building and parallel to it,
but separated by a space of about 10 feet, is the ore
shed in which the lead and silver ore beds are built
up. Lengthwise it is divided into three unequal parts.
The part nearest the furnace shed contains the
hydraulic elevators on which the charges are lifted to
the charge floor, and the weighing machines on
which the charges are weighed up. The central part
is occupied by a gangway for wheelbarrows, and a
tramway on which materials are brought in trucks
from a distance to the charge scales. The largest
third is reserved for ore beds. Each quadrangle or
bent formed by posts is called a space, and has a
number by which the ore stored in it may be identi-
fied. There are usually two or three large lead ore
beds, a like number of rich silver ore beds, a supply
of roasted matte, flue dust bricks, dross, and bar-
rings, kept in there. All other ores and materials
are stored in the yard in the open air and made ac-
cessible by laying movable tracks (flying tracks)
along the long sides of the beds.
Experience has taught that ores saturated with
moisture give better results in the smelting furnace
than dried ones, both in regard to tonnage and clean-
ness of slag. In accordance with this observation
the ore beds are thoroughly, drenched with water
from hydrants placed near them. The ferruginous
ores which have usually a clayey gangue retain then
regularly about 12% moisture, while the quartzose
and limey ones average from 3% to 8%. At some
smelters the charge is soaked with water in front of
the furnace door for the same reason.
The floor of the ore shed was originally made of
wood, but it may be imagined that, with all the shov-
eling done on it and the action of the water drained
fi'om the ore beds, there was no end of repairing.
This led to a trial of brick flooring, which proved an
entire success. The brick must be hard-burned and
laid on a foundation of slag concrete. A square
meter of paving, including cement concrete, costs
$2. Us. Where brick is good and cheap ore floors of
that kind can not be recommended too highly. In a
good many smelters too much dirt is smelted, which
IS dug out of the ground cm which the ore rests while
shoveling it into trucks. Thus it may occur that
more ore has been smelted than can be accounted
for.
There are five hydraulic lifts or elevators, which
receive their water directly from a steam pump.
The elevator shafts are connected at the top with
the charge floor by short bridges. Four elevators
are arranged in pairs, and the fifth stands opposite
the two end furnaces. Each pair of elevators serves
five furnaces. The fifth is kept in reserve in case
furnaces run too fast, or when any furnace is run on
a special charge.
In front of the elevators there are three weighing
machines of Fairbanks' make, so-called stock or
charge scales, with seven beams each. They are set
equidistant from each other, and opposite the cen-
ters of the elevator shafts. Each weighing machine
can accommodate five furnaces, but it was generally
so arranged that one machine served five, the second
one four, and the third one furnace, which was run
on secondary products. The other furnaces usually
ran on the same ore charge.
The ores and fluxes were weighed up in this fash-
ion : First, lead ore, which forms the largest part
of the charge ; then iron ore, then poor silver ore,
then rich silver ore, then roasted matte, and, lastly,
limestone. The lead ore was brought directly from
a bed in the charge barrow, but the other materials
were grouped around the scale platform in the order
in which they were intended to be weighed up. A
charge barrow comfortably holds 500 pounds of
charge, and this was called a half charge, two of
them being shoveled into the furnace simultaneously
from opposite doors. The head weigher of each scale
has to keep tally of the charges sent up on the ele-
vator , besides, there is an automatic counter at-
tached to the first ore beam. To prevent the scale
platform from getting jammed by fine ore or little
pebbles there is a pit under the scale, in which the
spilled ore accumulates. This is cleaned out once a
week. The scale must be tested for its correctness
every day.
The slag added to each charge was brought over
to the furnaces from the side facing their working
front.
The fuel is weighed up on the charge floor. There
are two platform scales for that purpose, one for five
furnaces. The fuel is brought up to the charge floor
in railway cars on an incline connected with a
straight trestle bridge running along the front of the
furnace building, and terminating in another incline
at the other end. Six standard gauge cars could be
placed on this trestle bridge, which afforded more
than twenty-four hours' supply. But this arrange-
ment is not to be recommended, on account of the
constant danger of a railway accident. Besides, the
trestles were of wood, and liable to be set on fire.
The surplus of fuel was unloaded on the ground below
the incline. The charge floor, having been intended
originally for six small furnaces, was too small for
the larger ones, and afforded no place for storage of
fuel, slag or other necessary material in case of fail-
ure of the regular supply. Hence it sometimes hap-
pened that a wheelbarrow train had to be organized
to bring up fuel on the incline from the stock pile
until a switch engine could be procured. This is only
one of the many vexations occurring almost daily in
a Mexican smelter.
It is known that an admixture of charcoal notably
increases the speed with which the charges descend
in a furnace when a dense or dirty coke is used, or,
in other words, it increases the tonnage, the goal of
every smelter. With this idea in mind, mixed fuel
was used at the Guggenheim works for several years.
The charcoal was made in ovens on the line of the
Monterey & Mexican Gulf Railway by an American
company, and, unlike the wretched stuff turned out
by Mexican coal burners, was of very good quality.
But the irregularity of supply, caused by wrangling
with the railway officials, and the inflammable nature
of the charcoal, finally led to its abandonment, ex-
cept for blowing-in and domestic purposes. It was
delivered at the works for $11.18 per metric ton,
which corresponds to $10.14 per 2000-pound ton.
The prediction of some metallurgists that mineral
coal would largely supersede charcoal in mixed fuel
received no recognition in these works. If coke con-
taining gaseous matter impedes reduction, how much
more will this be the case with bituminous coal, not
considering the ash, which is always high in the raw
material. Anthracite coal is very dense and not
porous, requires a blast of high pressure, and splin-
ters, thereby slowing the descent of the charges.
Hence this material is also to be rejected.
The only coke made in the country is the San
Felipe of the Sabinas coal field, on the line of the
Mexican International Railway. It is of such poor
quality that it has not found favor with custom smelt-
ers, and is only used by copper smelters and lead
smelters that do not have to treat purchased ores.
An analysis of the Sabinas coke afforded fixed carbon
79, ash 19.2, water 1.5, total 99.7.
It costs delivered at Monterey $10.84 per metric
ton. which is equivalent to $9.83 per 2000-pound ton.
In order to test quality and prices thoroughly coke
was imported in large quantities from Pennsylvania,
West Virginia, Indian Territory, Wales and Belgium.
European coke had to be left out of the quest 'u
account of its price, being higher by $5 a ton than
any of the others, and also on account of the long sea
voyage. Pennsylvania coke is too dense for rapid
work, and objectionable on account of the high ash
(12%) ; Indian Territory coke is too friable. Hence
there was only to choose between Alabama and West
Virginia. Analyses of these cokes are here appended :

The average price of all the United States coke
laid down at Monterey works was $12.64 per 2000-
pound ton.
Better transportation facilities decided in favor of
the West Virginia coke. It fills all reasonable re-
quirements in regard to furnace speed, reduction
power, and low percentage of ash. Its only draw-
back is its softness and consequent heavy abrasion in
transit, which amounts to at least 7% in weight. The
limestone is brought in ox carts from a quarry at
Topo Chico, 3 miles distant, and is delivered wher-
ever required at 85 cents a metric ton. As the cart
driver unloads this himself, this is cheaper than re-
ceiving it by rail, when laborers of the smelter would
have to unload it. The lumps are, however, too
large for convenient weighing, and have to be broken
into pieces not exceeding eight pounds. The stone is
then loaded on trucks and trammed to the charge
scales. The limestone is of a dark grey color, and is
incorrectly called "black marble." It contains from
1% to 1% of silica and from 54% to 55% of calcium
oxide. Limestones of such purity are not often avail-
able at a smelter. Usually they contain more silica,
quite frequently notable quantities of magnesia, alu-
mina and iron, and sometimes even nodules of marca-
site. The latter substance greatly interferes with
the production of a correct slag if unobserved.
In every smelter run on commercial principles the
great problem is to put through the largest possible
quantity of that ore from which the greatest profit
is derived with the least loss. In a custom smelter
this is, of course, the siliceous and sulphide ores,
while in smelters attached to one or more mines it is
the ore from these mines of which " tonnage " is re-
quired.
At the Guggenheim works the average ore charge
for the year 1896 consisted of 33% of siliceous and sul-
phide ores, 30% of lead ore, 32% of argentiferous iron
ore and 5% of roasted matte.
The matte is in the proportion in which it was pro-
duced. The limestone added as flux amounted to
7.82% of the weight of the ore.
The lead ore beds were made up so that they con-
tained about 27% of lead, and were of a basic charac-
ter. Since the principal lead ore supply came from
the Sierra Mojada (Encantada mine), where the lead
contents have dwindled down to 20% and less, it is
evident that ores richer in lead had to be put on the
beds to attain the desired 27%. The only ore of that
kind available in quantity was the ore from the firm's
Reforma mine in the State of Coahuila. This ore
was, however, quartzose. and contained also barium
sulphate. Other rich lead ores could only be picked
up in small lots. Whenever the Reforma failed to
come in the lead contents would drop at once. In
the following are given examples of the composition
of some lead ore beds :
Ag. Mois-
Si02. Fe. CaO. Zn. S. Pb. oz ture.
I ..13.6 21.6 3.3 2.3 1.5 27.0 15.4 12

III . . . 6.5 28.5 2.0 1.2 1.0 18.7 7.8 12
In some of the ores composing these beds, notably
in Encantada, there is also arsenic, originating from
arsenate of lead, and sulphate of baryta. The arsenic
is only interesting from a commercial point of view,
and the sulphate of baryta is present in such small
quantities that it does not exercise any influence on
the slag.
Bed No. I is of normal composition.
Bed No. II is abnormal in regard to lead and sil-
ver, and
Bed No. Ill is very bad, and would indicate that
something unusual had happened.
The basicity of No. Ill shows at once that a large
addition of siliceous ore will be required to satisfy it,
which will lower the lead percentage of the furnace
charge to the danger point.
The ferruginous ores ran about as follows :

It will be seen that the stock of copper January 1,
1899, was 54,361,470 pounds, and the stock on hand
December 31, 1899, was 88,722,559 pounds, an in-
crease of over 34,000,000 pounds. This increase was
due to the falling off of exports, which were 50,000,000
pounds less in 1899 than in 1898. This decrease was due
to the fact that copper, being higher in price than for
some years previously, the foreign consumers used
up their available stocks, bought at a lower figure,
but after January 1, 1900, these stocks being practi-
cally exhausted, they commenced placing large
orders for copper in the United States markets,
which during the past six months have very largely
increased the exports of the metal, the copper ex-
ports from January 1 to June 30, 1900, being four-
fifths of the amount exported during the twelve
months ending December 31, 1899. The home con-
sumption of copper in 1899 was over 117,000,000
pounds greater than" in 1898.
This table also shows that Montana, Michigan and
Arizona produced nearly nine-tenths of the produc-
tion of the United States, or nearly one-half of the
world's production. In comparison with 1897, Mon-
tana's increase was less than 1%, Michigan's not
quite 1%, and Arizona's over 50%. — Boston News

A California Stamp Mill.
To TBS Editor:— Please describe a California stamp
mill so that ene who doesn't tenon anything about it run
Ome idea of haw it is built and how il works.
Boston, Mass.. Aug, 2. 1900. .1. D. S.
It would be easier to describe it to one who does
know something about it, as any description of it
must necessarily be technical. Our Boston corre-
spondent would do well to get some catalogues from
our advertisers, which give excellent illustrated de-
scriptions of stamp mill practice.
However, the following is given in answer to the re-
quest :
1 lalifornia stamp mills are built in batteries usually
of live stamps each, and ordinarily at first the mill
-is of one battery only, but is so arranged that
additional batteries may be placed in position when
the mine is found to warrant the expenditure. The
price of the mill is estimated at so much per stamp,
usually costing about $1000 per stamp about the time
the mill is ready to begin crushing ore (though there
is a difference in these things. On page 188 is de-
scribed a new Arizona stamp mill — a 40-stamp mill —
that has cost $150,000. Our Boston inquirer might
read that article in connection with this.)
The weight of the stamps runs from 050 to 1200
pounds each. A medium-weight stamp, about 750
pounds, is most commonly used and is suitable for
crushing ordinary ore. The estimate of cost includes
the boilers, engines, amalgamating plates and all else
that is necessary to handle free-milling ore.
Each battery consists of an integral cast iron mor-
tar having a rectangular bed, within which dies are
arranged. Each die consists of a square base, having
upon its top a cylindrical projection which is just the
size of the stamp and arranged to receive the blow
from its respective stamp. A layer of sand or ore is
placed upon the bottom of the mortar before the dies
are placed in position, to form a cushion to prevent,
the blows from the stamp breaking the mortar. The
mortar is cast with a heavy frame above it, and in
this frame are provided guideways in which play the
stems of the stamps ; above this frame is another
wooden frame, in which play the upper ends of the
stems. Between the two frames is arranged the cam
shaft, which is provided with one cam for each stamp.
The cams are shaped like a heavy, strong sickle and
are from 8 to 14 inches in length. The handle end is
provided with an opening through which the cam
shaft passes, and a key secures it rigidly in place.
The stamp stems are round shafts of iron, and in a
battery of 750-pound stamps the stems are about 31
inches in diameter. To the lower end of the stem is
keyed a cast base, having a socket in which fits the
stem of the stamp shoe, which is from 6 to 10 inches
in diameter and about 1 foot in length when new.
This shoe is also keyed in the socket so it can be eas-
ily removed when necessary. Upon each stamp stem
above the cam shaft and in the path of its respective
cam is keyed a collar called a tappet, and at each
revolution of the cam shaft each cam engages with
its respective tappet and lifts the stamp until the
cam passes from under the tappet and lets the stamp
drop. The cams are arranged spirally around the
shaft, so that the stamps are raised and dropped in
regular succession, and not all at once.
The rear of the mortar is closed by a thick, wooden
plank, which is wedged tightly in grooves in the mor-
tar, while the front is closed by means of a screen of
wire cloth or of slotted sheet metal. These screens
are of different degrees of fineness, running from 40
to 100 openings to the inch, and the fineness of the
screen depends upon the character of the ore. When
this gold is coarse a 40-mesh screen will answer, but
if the gold is fine a 60 or 80-mesh screen will be re-
quired. Very fine gold may require a 120-mesh
screen, but this is unusual. The screens are fastened
on frames which fit into grooves in the mortar box,
and are wedged firmly in place by iron wedges.
Strips of blanket are tacked along the edges of the
frame, so that when in place the joints will be water
tight, and all the matter which escapes from the mor-
tar box will have to pass through the screen.
The drop of the stamps — that is, the distance they
fall — is regulated by adjusting the tappets of the
stamp stems. A 7i-inch drop is enough to crush or-
dinary quartz, but hard quartz sometimes takes a
9-inch drop or more. Each stamp is arranged to
drop from fifty to ninety times per minute, dependent
upon the distance it falls. If the drop is 9 inches and
the speed ninety times per minute, the cam will usu-
ally catch the tappet before the shoe hits the die, and
of course the ore will not be crushed if this is done,
the cam receiving the full force of the blow.
The ore is placed in a large hopper, which has its
lower end closed by one side of a large horizontally
arranged iron plate, which is connected by means of
cog wheels ; a ratchet and an arm with a plunger
which extends upwards far enough to be struck by a
tappet on one of the central stamp stems. This
plunger can be regulated so that the tappet will only
strike when the stamp has sufficient ore beneath it to
keep it from pounding iron, as it is termed, when the
shoe hits upon the die itself. When the tappet hits
the plunger plate it is rotated an inch or two and
the ore is carried against a scraper, which causes it
to fall into a mortar box ; when too much ore gets
beneath the stamp the tappet does not strike the
plunger and no more ore is fed to the stamps until
enough has been crushed and washed from the mortar
to allow the tappet to again strike the plunger.
In front of the mortar is arranged the apron and
amalgamating plate, upon which is discharged all the
crushed ore which passes through the screen. Amal-
gamating plates are also arranged in the battery.
They are of copper and plated with silver. Below the
apron is arranged a long sluice box, which sometimes
has its bottom covered with amalgamating plates,
over which the ore all passes on its way to the slime
pond. If the ore is hard to work, it is common to run
it through mullers or large cast iron basins, each hav-
ing a rotary grinder therein. When everything is
ready the mill is started. Nearly all the free gold is
amalgamated by the quicksilver on the plates in the
battery. Each stamp should crush about one ton of
ore in eight hours.

Quantitative Test for Molybdenum.
To the Editor: — Please publish through "Concen-
trates " a quantitative test for molybdenum.
Walla Walla, Wash., Aug. 1.
Correct reply is too detailed for answer in "Con-
centrates."
To estimate molybdenum quantitatively it-must be
obtained as a neutral molybdate, which is then pre-
cipitated with a neutral solution of mercurous nitrate.
The yellow precipitate which falls down is washed
with a solution of mercurous nitrate, dried, and then
either heated in a stream of hydrogen, when molyb-
denum dioxide is formed, or it is ignited with a
weighed quantity of anhydrous lead oxide until all
the mercury is driven off. The increase of weight of
the residue gives, then, the amount of trioxide pres-
ent. To determine the amount of molybdenum avail-
able in the ore molybdenite, about 1 g. mineral is
digested with 25 c.c. concentrated nitric acid for two
hours in an Erlenmeyer flask, in order to convert the
mylybdenum into molybdic acid. The latter is dis-
solved in ammonia and filtered off. The residue is
treated a second time with nitric acid and ammonia.
The combined filtrate is then acidified with nitric
acid and evaporated to dryness. The molybdic acid
is separated from the dry ammonium nitrate by leach-
ing with 50% alcohol, which dissolves only the ammo-
nium nitrate. The molybdic acid is then collected
upon a weighed filter, or, better, is dissolved in nor-
mal ammonia and the excess of alkali titrated with
acid. Molybdenum may be estimated indirectly by
adding an excess of lead acetate to a solution of
alkali molybdate, filtering off the lead molybdate and
determining the amount of lead in the filtrate, by any
trustworthy volumetric method of determining lead.
Schindler describes in the Journal of the American
Chemical Society, November, 1895, a method whereby
lead acetate is added to an acidified solution of a
molybdate until the latter ceases to give any colora-
tion on a test plate with tannin. Brearly has modi-
fied this method : Add lead acetate and use the tan-
nin reaction as long as available. Pour a little of the
hot solution through a ribbed paper, test the filtrate
first' with lead acetate and, if necessary, with sodium
molybdate. Generally the first test will show that
some molybdenum is still unprecipitated, and the in-
tensity of the cloudiness indicates, approximately,
the amount. The one or other reagent is added as
required, and the solution tested in this way until
with absolute certainty neither sodium molybdate nor
lead acetate is present in other than negligible quan-
tities. As the solution is passed through the same
filter until the end is reached, there is no loss through
absorption of the paper. Large amounts of metallic
salts do not interfere.

The Union Iron Works of San Francisco have just
completed a 40-stamp mill for the Octave G. M.
Co., near Weaver, Ariz. It is more than usually
complete in every detail, and, representing modern
construction in plants of its class, is of more than
passing interest.

The mine is situated about 11 miles east of Con-
gress, Ariz. The veins in this belt all strike east aod
west and dip to the north about 25°. The Octave
vein matter is firm, white quartz, containing sul-
phurets of lead, iron and zinc. The walls are clearly
defined, there being a little gouge on both sides. The
formation is decomposed granite and diorite.
The ore is hauled in two-ton cars by a mule over
the trestle to the crusher building, about 200 feet
from the mouth of the tunnel. There are four griz-
zlies and two 10xl6-inch jaw crushers, so arranged
as to provide storage for about forty tons of ore
( room. The clean-up rig is treated as an important ad-
i junct. The room is 24x30 feet, forming an extension
j to the battery room ; in it are located an amalgam
I barrel, a brick retort and melting furnace, work
benches, wash trays, amalgam strainers and safes.
The floor is cement concrete, laid with slope form
all sides to a sump in the center, from which lost
quicksilver and amalgam are easily recovered.
The concentrator room also has a cement floor,
with the open tailing sluices molded in solid cement.
The floor slopes from all sides to the sluices, and all
leakage is washed down with the tailings through an

It was designed and built under contract by the
Union Iron Works and turned over in running order
after trial run of ten days.
The property was known as the old Rumer mine
and had been worked for several years in a small way
until two years ago. The property was examined
and reported upon by D. J. Jones, and, upon his re-
commendation, was purchased by the Octave G. M.
Co. and active development work commenced.
above crushers and 500 tons below — all of which is
distributed by gravity through steel lined chutes into
the mill bins proper, which have additional capacity
of 700 tons. The crushers are driven by a special
steam engine located below.
The batteries are of the back-knee type — each
5-stamp battery being driven independently by belt
from line shaft below the feeder floor. Other new
features are cast iron sectional stamp guides, iron
frame hanging ore feeders, solid concrete mortar
blocks, movable apron plates and sand bucket run-
ning on trolley along front of batteries to clean-up
iron pipe to the settling tanks, from which the water
is pumped back to the battery supply tank above the
mill.
The tailings are all treated by the cyanide process,
with some interesting modifications from the usual
practice. This will be the subject of a later
article.
The mill is driven by steam power generated in a
battery of three 70 H. P. boilers, with independent
settings, allowing for one boiler to be constantly in
reserve.

The engine room, located between boiler room and
mill, has a cement Boor, with walls and ceiling double- ,
boarded, with tarred paper between, protecting the
machinery from dust and diminishing toe noise.
.\ compound Corliss engine drives the mill, being
coupled direct to battery line shaft In the engine
room is also located an electric generator of 500-lTght
capacity, driven by an automatic compound engine,
furnishing lights for- mill, mine and offices and power
for cumulating pumps at cyanide plant. The en-
gine mom is nicely finished, all the interior being
painted while, and. with marble switchboard, orna-
mental gauge panel, oil stands, pictures, etc., marks
quite an advance over the ordinary mill engine
room.
One of the most important features in connection
with the plant is the machine shop, occupying a spe-
cial building 24.\SO feet, containing lathe, dull press,
emery grinders, bolt cutter, forges, etc., and com-
plete stock of iron, pipe and fittings, as required for
general repair work about the mine and mill.
It is not often that a mine is so thoroughly equipped
in the beginning ; smaller plants are usually erected,
and are added to from time to time ; but the Octave
people have recognized the economy of making their
improvements Brat— the development of the mine
having fully warranted the expenditure.
New Discharging Device for Transfer Coal Barge.
The steel hull of the old U. S. monitor Comanche is
now being used by the Pacific Coast Company in San
Francisco bay as a transfer coal barge. After being
sold by the Government the vessel was dismantled
and the machinery entirely removed. It now has a
carrying capacity of 1200 tons of coal, is 190 feet
long, 36 feet beam and has 20 feet depth of hold. The
iron saddles bolted to wooden posts at bow and stern
of the barge. These posts, 133 feet apart and 42 feet
high, are built of 10xl4inch timbers, braced with
Uix Ht-inch timbers, and are secured by four 11 -inch
and two H-inch rod-steel back stays, which are fast-
ened to straps riveted to the hull. The ends of the
track cable are each attached to two l*x4-inch back
stays by means of a thimble, spliced into the end of
the rope, and a turnbuckle by which the required
tension is maintained.
On the track rope runs the trolley, the frame
of which is made of 5-inch steel plates. This is sup-
ported by two 14-inch track sheaves above, and main-
tained in position by two 10-inch guide sheaves below
the track cable. It is moved fore and aft by means
of an endless wire rope 3 inch in diameter passing
back and forth over head sheaves near the tops of the
supporting posts to a grooved drum on the hoisting
engine, in the lower portion of the trolley are two
sheaves 18 inches in diameter. Over one of these
passes the rope for closing and hoisting the bucket,
and over the other passes the rope for opening and
lowering the bucket ; thence both ropes pass over
head sheaves in the stern post to their respective
drums on the hoisting engine. These ropes are 3-inch
crucible cast steel, composed of six strands of nine-
teen wires each about a hemp center. The power
operating this device for raising, conveying and
dumping the bucket consists of a 00 H. P. triple-
drum, link-motion, double-cylinder 10xl2-inch engine
located at the stern. One man operating this engine
can discharge into the hopper amidships two loads a
minute.
From the hopper the coal gravitates through
chutes to elevating buckets on either port or star-
board side. These buckets, which are of the same
capacity as the grab-bucket, travel in vertical guides
to a maximum height of 50 feet'.
When loading, at the bottom of the guides, these
buckets rest upon scales, where the weight is taken.
After receiving its load the bucket (which is of the
side-dumping type) is raised by an
auxiliary engine located under the hop-
per and dumped automatically by mov-
able trips into a chute stationed at the
desired height. This chute, 24 feet
long, extends over the side of the barge
at an angle of 40°, and can deliver coal
into a vessel or bunker at a maximum
difference in deck levels of 30 feet.
Grease on Quicksilver.
Written by W. S. Welton
One of the most potent enemies to
amalgamation is fatty or resinous sub-
stances. Probably there are few more
the black saud accompanying these, will rise to the
surface of the water- and continue floating upon it un-
til the miner, with some difficulty, causes these parti-
cles to fall by spraying water upon them with as much
force as possible. The above effects are apparently
caused by a minute portion of grease from the lingers
becoming attached to the particles of gold and sand.
The disastrous effects which may be produced in the
amalgamation of gold and silver by a minute portion
of oil, petroleum, grease or resin in the water are re-
markable. These substances appear to be specially
attracted to gold and mercury, and for this reason at
hydraulic mines it has been found necessary to pro-
hibit the washing of clothes in the ditches, or the
washing of plates after the men's dinners, in any of
the streams dumping into the ditches or sluices.
When the surface of the gravel banks has been pre-
viously occupied by camps or dwelling houses, the
mercury in the sluices becomes sickened by the grease
resulting from the surface soil upon washing such
portions of the bank. The continual wearing away
of the blocks and linings of the sluices sets free a con-
siderable portion of gum or resin, which adheres to
the gold and mercury, and is detrimental to amal-
gamation.
Mercury contaminated with grease or resin be-
comes too sluggish to run. Comparatively large
grains of gold will float upon its surface without be-
ing amalgamated. Its brightness is changed to a dull,
leaden color, and it will flour easily. The distillation
will not purify mercury or grease or resin, as these
substances pass over in retorting and condense again.
Under these circumstances the writer has found
great benefit from frequently washing the mercury in
a strong solution of potash obtained by leaching wood
ashes ; the flouring and sickening are thus overcome,
and the yield of silver or gold much increased.

The device for discharging was designed by the
California Wire Works, San Francisco, and consists
of a 2240- pound grab- bucket, operated by means of a
movable " trolley " running on a track cable sup-
ported by wooden structures at either end of the
barge.
The track cable is made of plow steel 2} inches in
diameter, being built up of seven strands of seven

expert washers of gold than the South American
miners, and they are so fully aware of the bad
effects of grease in the catching of gold that they
are exceedingly jealous of trusting their batea to the
hands of a stranger. The South American miner
hides his batea in the thatch of his house for fear that
his wife or children may get it, and carefully washes
his own hands with sharp river sand before he com-
mences work, for fear of the smallest quantity of
grease interfering with his operations.
Strangers, on seeing auriferous sands panned for
the first time, can hardly ever resist the temptation
to pick out with their fingers the colors or specks of
gold as soon as they appear, and so soon as they do

The Bell Gyrating Disc Engine.
Written for the Mining and Scientific Press.
Ever since the steam engine came into general use,
it has been the aim of steam engine builders to con-
struct an engine capable of high speed without the
attendant vibration caused by the reciprocating
ferred to later on. B, C are steam and exhaust pipes,
respectively. D, D are bonnets bolted to the cyl-
inder, and in which the crank pins gyrate and the
crank rotates, transmitting its motion to the engine
shaft E. P is the driving pulley, G- is the fly wheel,
H, H are the journal boxes and I is the base on which
the engine rests.
The novel feature in this engine is the gyrating
type, and to that end numerous types of rotary en-
gines have been built. But, while this class of ma-
chine may have been satisfactory in that respect,
their excessive consumption of steam has, up to the
present, prohibited their use on a commercial scale.
The Bell gyrating disc engine, herein described, is
manufactured by MeFarlane & Co., Denver, Colo.
It has all the advantages sought for in a rotary, and,
Mining and Scientific Press
piston. It is a metal disc whose diameter corre-
sponds to the diameter of the cylinder and deter-
mines the size of the engine.
The disc is made with a sphere in its center, as
shown in the illustration at C (Pig. 2), the sphere and
disc being in one piece. The outer edge of the disc
is recessed to receive a spring packing ring A, whose
duty is identical with the spring ring of any recipro-
the crank pin and is driven tightly into the disc and
sphere.
Pig. 3 shows the disc C and the crank E in posi-
tion, but with the cylinder entirely removed. The
crank is keyed to the main shaft I and is bored to
receive the crank pin B.
Fig. 4 shows the lower half of the steam cylinder
with the diaphragm A in place. This diaphragm, in
conjunction with the disc, divides the cylinder into
two parts, one part containing live steam and the
other the exhaust steam, besides preventing the disc
from rotating around its axis. D and C are steam
and exhaust ports, respectively.
Fig. 5 shows the cylinder heads A, A, diaphram b,
disc e and crank f in place, the top and bottom parts
of the cylinder and bonnets being removed.
The cylinder heads are cone-shaped on their inner
face and so constructed that the disc lies against one
head on one side at c and against the other on its
opposite side at d, making two lines of contact be-
tween the disc and cylinder heads diametrically oppo-
site each other and on opposite sides of the disc. The
cylinder heads are each provided with a socket which
acts as bearings for the sphere.
The motion of the crank pin may be illustrated by
the movement of the forearm in describing a circle
with the hand, while keeping the wrist rigid and the
elbow at rest and with index finger in the crank pin
journal. Thus, it will be seen that while the crank
pin gyrates, it does not rotate on its axis, but trans-
mits a rotary motion to the shaft through the crank.
The nominal speed of this engine is 1000 revolutions
per minute. Its weight per given horse power is
considerably less than that of the reciprocating en-
gine. The manufacturers say that it has no dead
center and is instantly reversible, which would make
it an ideal engine for a hoister. There are no valves
to set or get out of order. In a hoister the steam
and reverse levers are embodied in one. There is no
claim of originality, except in the new application of an
old principle. MeFarlane & Co. , of Denver, Colo. , who
make it, say that it will lift, when applied to a hoister,

it is claimed, has none of its failings, but at the same
time embodies the available good points of the re-
ciprocating piston engine, inasmuch as the steam
acts on its piston with a direct and positive pressure,
susceptible to steam cut-off and the use of it ex-
pansively.
This is a distinct departure from all forms of the
reciprocating piston engines and might be termed an
engine with a continuous stroke. This fact, together
with its few moving parts and simplicity, causes it to

MINING SUMMARY.
ALASKA.
A emnpany has Imm.ui formed at Dawson
in buy machinery at Nome; to send a rep-
resentative to Nomoand wherever he finds
an\ stranded minors to pay their faro back
bone for their machinery. Late arrivals
from Nome bave reported that thousands
of valuable machinery are lying on
tho beach covered by the high tides and
behiff covered by the drifting sands. This
uiiichincry was taken to Nome to work
the beach and cost thousands of dollars.
Those who took this machinery to Nome
did not doubt that the gold was there,
and their only doubt was us to whether
the machinery would have large enough
capacity. Thousands of feet of hydraulic
hose are lying on the beach at Nome.
This hose was manufactured to run out
into the surf, and, by attaching an ongine,
to suck the sand inward. Nearly every
arrival had some scheme to get the gold
that was in keeping with their imaginary
powers. The steam boilers that are on
the Nome beach and other machinery of
that description will find a ready market
along tho Yukon, and the thousands of
feet of hose will be used as pipe lino to get
water to the Anvil and other creek claims.
P. C. Hammond has contracts with the
Westlnghouse Kl.eti-ic Co. for an electric
power plant to transmit power from
Sheep creek under the channel to the
Heady Bullion and Mexican on the other
shore. The Alaska Water Power Co. 'is
credited with having a contract from the
Alaska-Treadwell Co. for the use of 850
H. P. throughout the year as a minimum
amount, water to bo takon from the creek
at 700 feet above tide water; the complete
installation is to cost $40,000. It is calcu-
lated that at the contract price the Tread-
well group will annually save $20,000.

the county and against the recorder. This
is to recover money retained by Lee as
fees for recording mining location notices.
The recorder claimed that under the law
and the Supreme Court's decisions he was
not compelled to record such notices, and
that therefore the fees belonged to him
and not to the county. The Supreme
Court rules that, while its decisions were
in accordance with the law at the time
they were given, the statutes have since
been changed and the decisions are not
applicable. Accordingly the recorder
must pay such fees over as county money.

TELLER COUNTY.
(Special Correspondence). — The Granite
mine, on Battle mountain, belongs to the
Smith-Moffat interests and has been con-
siderable of a shipper from the sixth and
seventh levels. Within the past few
months the shaft has been sunk to 1000
feet depth, where a station 10x50 feet and
18 feet high has been cut. From the shaft
at this depth it will require a 250-foot
crosscut to reach the ore body. The large
electric hoist put in here last year has
been discarded and a first-motion steam
hoist will replace it. The shaft house is
also being enlarged and the management
hopes to be shipping from the tenth level
within sixty days. C. H. Cannam is in
charge of the work.
The new equipment at the Ajax, includ-
ing new boilers and hoist, is operating
satisfactorily. The intention is to put
in automatic stokers here. The Ajax
shaft, now at 600 feet, will be sunk to 1000
feet depth.
The Mary McKinney's shipments now
run about 80 tons per day, the ore coming
from all the levels from 50 feet down to
the 400 level. One-half the ore runs an
average of one and one-quarter ounces
gold and the other half will average as
high as three ounces. Most of this ore goes
to the smelters, whose buyers are in the
market for all ore they can get that runs
as high as one ounce gold to the ton.
While mine operators cannot be induced
to talk freely as to present smelter rates,
it is evident they are getting a much more
favorable rate than the smelters were
willing to make three or four months ago.
Relations of the mines with the cyanide
and chlorination mills, as to rates, do not
seem to be entirely satisfactory, though
the increasing demands for ore on the
part of the mills and smelters are certain
to bring about an adjustment. It is be-
lieved the district is in position to furnish
a tremendous tonnage of milling ore and
this will be done as soon as rates shall be
adjusted on a mutually satisfactory basis.
The Nugget shaft is being operated by
the Nugget Co. They appear to have
the extension of the well-known Jack Pot
vein, from which thirty tons of three and
one-half-ounce ore are being shipped per
week. The Smith lease on part of the
Nugget grounds is shipping forty to fifty
tons per day of ore, said to average $70
per ton, from a vein running parallel to
the Jack Pot.
The Jack Pot group belongs to the
Woods combination, who have a three-
years lease on the Morning Glory shaft of
the Work, which adjoins the Jack Pot.
The production of the latter will be
hoisted through the Morning Glory shaft.
At the Jennie Sample, on Raven, an air
compressor is being put in. A station is
being cut at 500 feet depth. Considerable
ore has been shipped from this mine
which averaged five ounces gold.
The Elkton is spending a large sum on
improvements. The shaft is being made
three-compartment from the surface to
the fourth level. In sinking from the 400
to the 800 level the three-compartment
size was made and present work is to
make the upper section of the shaft con-
form in size to the lower section. At the
800-foot station a Prescott 800 - foot,
straight-lift pump is being put in place.
Its capacity will be 1000 gallons per min-
ute. Material for a 55-foot steel gallows-
frame has been ordered, which will soon
replace the wood frame now in use. Its
structure will be such as to make the ore
landing 25-feet above the collar of the
shaft. An ore house is in course of erec-
tion, which will afford facilities for hand-
ling 150 to 200. tons per day. A first-mo-
tion hoist, 20x48, double reel, capable of
hoisting from 2000 feet depth, is being put
in. The Elkton is shipping now from
1000 to 1200 tons of ore per month, which
averages $100 per ton, all of which goes to
the smelter and comes from the fifth and
sixth levels. As soon as the new pump is
ready for work the ore body will be
tapped at the seventh and eighth levels.
The works of the Eagle Ore Sampling
Co. started up on the 9th inst.
Victor, Aug. 10.
During July the Elkton mine is credited
with having shipped 1000 tons of ore
yielding $125,000. The station in the
eighth level at a depth of 800 feet is cut
and a pump in place. Work will begin on
the crosscut from the Elkton shaft to the
Elkton vein, 40 feet distant. When the
dyke carrying this vein is broken into
there will be a flow of water, which it is
designed to handle with the 1000-gallon-a-
minute pump at the eighth level.
The Gold Belt M. & I. Co. has sold the
St. Patrick G. M. Syndicate the St. Pat-
rick claim, in the limits of the city of Vic-

duced 38,548 tons, containing 97,428 ounces
gold and 6701 ounces silver ; gross value,
$1,951,219, or $50.62 per ton. Treatment
charges were $311,908, or $8.09 per ton ;
freight, $103,026, $2.67 per ton: total,
$414,934, or $10.76 per ton; net value,
$1,536,285, $39.86 per ton. During the
first six months average number gallons
water pumped 50,000,000 per month, and
for the year 37,000,000 gallons per month,
at a monthly cost of $6500. Amount of
development work done during the past

Boulder.
LKWIS AND CLARKE COUNTY.
From Marysville the Helena Indepen-
dent is told that the report of the shut
down of tho Drum Lummon mino was
exaggerated. It was the mill that shut
down and a few miners who were getting
out ore for the mill. The prospect work
goes on moro actively than before the
mill shut down, and tho force employed in
doing this work has been increased.
The North Star mine is being developed
through the 400-foot level of the Drum
Lummon, and five teams are taking this
ore to the Bald Mountain mill.
J. H. Longmaid of the Belmont mine at

Supt. Buzzo at tho Alice M. Co., Wal-
kervUle, has eighty men at work, some of
them boing lessees. The property is pro-
ducing 600 tons per month, the ores carry-
ing from 18 to 100 ounces silver and 75 cents
to $10 gold. Supt. Buzzo is hopeful of sev-
eral new processes for successfully treating
zinc ores; one by B. B. Sadtler, who
lines the retorts with a chemical combina-
tion that resists the action of. the iron in
melting for ninety days, and who expects
to utilize zinc ores carrying 10% to 15% of
iron. Heretofore the presence of 2% of
iron has proved a serious objection in zinc
ores in the United States, but in Europe
zinc ores have been treated carrying 10%
of iron, due to cheaper labor and different
processes. A company is being organized
to work under that process, its works to
be located near Basin. Another process
is being developed for leaching out the
zinc, leaving the iron and silica containing
the metallic values for treatment.
Plans and specifications have been
drawn for the reconstruction of the Par-
rot mining plant. The hoist is to be re-

Placer mining operations at Wreck bay,
Vancouver Island, are of increasing mag-
nitude. The large flume running 0 miles
inland from the beach is about completed;
modern machines for the washing of the
gold from the sand are being put in. The ton
or yard of beach land that is run through
the machines now operated return on an
average $4 gold. Forty men are employed
on the flume. The bay is exposed to every
blast, and, as the big seas roll in, parts of
the embankments are carried seaward,
and then the deposits are swept shore-
ward, this reactionary process accounting,
it is thought, for the prevalence of the gold
on the beach.
V. R. Pierson reports placer gold on the
west coast of "Vancouver island, 12 miles
south of the Helga mining properties. He
says there is a 3-mile stretch of beach at the
point indicated where the gold is of all
sizes, from half a pea down to mere atoms.
The formation of the ground is, first, 18
inches of sand and gravel; then 30 inches
of gray and black sand carrying placer
gold; then 12 inches of clay; then 18 inches
more of pay streak, richer than the first
encountered; then the clay hard pan.
Ashcroft, Cariboo, reports that R. H.
Campbell of California has broken through

gravel. Mr. Campbell put in heavier ma-
chinery and sunk 60 feet in bedrock, then
started to drift across the channel. At
300 feet, not having struck the channel,
he made an upraise of 15 feet, and is now
stated to have broken through into
gravel.

able gain in the popularity of Western
mining securities in the East. With the
introduction of scientific and business
methods in the conduct of mining enter-
prises and the improvements in the meth-
ods of treatment, mining has been made a
business as much as a speculation. It is
beginning to be recognized that a mining
enterprise is made successful by putting
men of scientific training and the widest
possible experience at the head of opera-
tions and business men of capacity at the
business end. There is, in consequence, a
strong movement towards mining as a
business."

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co.'s Scien-
tific Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Bottle Faucet Attachment. — No.
655,345. Aug. 7, 1900. H. A. Knight,
Alameda, Cal. The object of this inven-
tion is to provide for the more perfect
charging of carbonic acid gas and the like
into bottles containing liquids, whereby
the latter are made effervescent, and a
means for withdrawing the contents of the
bottle in small quantities as needed with-
out injuriously reducing the quantity or
pressure of gas in the remaining liquid,
the whole designed to operate without
the removal of the stopper and connected
parts. It consists of a tubular screw-
threaded stopper fitting corresponding
threads in the neck of the bottle, having a
flange and washer to form a joint, and a
tubular extension above and below the
stopper. A cap is provided with a stop-
per to fit this extension having a central
and packed valve stem, and a valve at its
lower end closable upon a seat within the
stopper. The cap also forms an exterior
screw-threaded sleeve fitting upon the
outside of the stopper extension, and an
inwardly open spring-pressed valve is
provided for charging the bottle, this
valve having a stem extending through
the stopper, and the cap upon the upper
end with admission channels formed
through it.
Method op Making Superphos-
phates.—No. 655,458. Aug. 7, 1900.
Heinrich Saxl, San Francisco, Cal., one-
half assigned to A. A. Adler, of same
place. This invention is designed to
provide a concentrated easily soluble
phosphoric acid, and to produce super-
phosphates rich in fertilizing material. It
consists in first producing normal super-
phosphates by subjecting the phosphate
of lime containing the material to the ac-
tion of sulphuric acid, then mixing the
mass with water, separating out the liquid
and evaporating it, then mixing with the
product the second body of phosphate-
containing material, withdrawing the re-
sultant mass and separating the liquid
therefrom.
Grain Drill Attachments. — No.
655,334. Aug. 7, 1900. Wm. Falconer,
Selma, Cal. This invention relates to an
attachment for grain drills of that class in
which the grain is delivered from a reser-
voir or feed box through tubes and shoes
at the lower ends, these shoes forming
drills to receive the grain, and the object
is to provide a supplemental attachment
by which the pressure upon the heel of
the shoe can be regulated so as to insure
the drill being made of sufficient depth in
hard or lumpy ground, and to prevent it
from going too deep where the ground is
soft and sandy. The front ends of the
shoes have elastic connections and sup-
ports ; standards are flexibly connected
with each shoe at the point in the rear of
the forward connections and extending
upwardly from their point of attachment.
A fixed bar having holes through which
the standards are slidable acts to limit the
movement of the standards by reason of
pins or stops which are adjustably fixed
to the standards to contact with the bar.
Spiral springs surround the standards,
the ends pressing respectively against the
bar and against the adjustable stops so
that pressure is exerted to force the heels
of the shoes into the ground, while other
pins or stops fixed to the standard above
the bar limit the depth to which the shoes
are forced in the ground when the latter is
soft.
Axle Lubricator. — No. 655,347.
Aug. 7, 1900. J. E. Ludwig, San Fran-
cisco, Cal. This device is designed for the
lubrication of vehicle axles without the re-
moving of the wheels, and is particularly
adapted for heavily loaded vehicles, such
as large wagons loaded with freight which
is to be carried for a number of days be-
fore reaching its destination. It consists
of a lubricant reservoir, with means for
connecting it with the outer end of the
axle to be lubricated, and means for form-
ing a tight joint therewith. With this is
a device by which the lubricant may be
forced into the space between the axle and
axle-box, this device being in the form of
a plunger or piston movable in the lubri-
cant-containing cylinder, so that when the
piston is forced inwardly, the lubricant
will be passed through the connecting
passage and into the space between the
axle-box and the axle in sufficient quanti-
ties for the purpose.
Hop Bleaching and Drying Kiln. —
No. 655,330. Aug. 7, 1900. J. & A. B. C.
Dowdell, St. Helena, Cal. This invention
is designed to bleach and dry hops. It
consists of a room or compartment having
a foraminous floor adapted to support the
hops to be dried, and in conjunction with
this of a covering which may be drawn
over the surface of the hops to confine and
prevent the heat and moisture from escap-
ing therefrom during the process of
bleaching. The sulphur fumes are pro-
duced in any suitable manner and delivered
from below so as to rise into the hops, and
are there retained by the superposed
covering until the bleaching is perfected.
The covering is then withdrawn, and heat
being applied the drying will be completed
in the usual manner. In this manner the
hops are very perfectly bleached with a
minimum expenditure of time and ma-
terial.
Concentrator. — No. 655,470. Aug.
7, 1900. W. H. Washburn, of Oroville
Wash., one-half assigned to J. B. Wash-
burn, Baker City, Or. This invention is
an improvement in concentrators of that
class of the endless traveling and shaking
belt type. It consists of a water supply
device with discharge openings, a dis-
tributer or spreader having oppositely in-
clined surface adapted to reciprocate be-
neath these openings and having a series
of divergent channels alternately supplied
from the water-box. The distributer has
also a series of discharge openings at op-
posite edges and gates by which the
amount of water delivered to the chan-
nels is regulated.

Under date of Aug. 2, Jas. Lewis & Son
of Liverpool report:
The great developments now taking
place in England in the application of
electric traction and power; the addi-
tional telegraph cables about to be laid
(including the Pacific cable of 8800 miles,
estimated to require some 4000 tons of
copper); the large quantities of copper
used for ammunition; and the additional
5000 tons required for the manufacture of
sulphate of copper during the next six
months; will necessitate a great increase
in the consumption of copper in this coun-
try for the rest of this year.
As the stocks held in the United States
are much less now than a year ago, and
shipments from thence during the second
half of this year promise to be much less
than during the first half, the increase in
the production of the United States of 8%
and in the total supplies to Europe and

A Money Maker in Nicaragua.
MUREA GOLD MINING COMPANY, NICARAGUA, C.
Nicaragua, June 20, 1899.
GATES IRON WORKS, CHICAGO.— Gentlemen:
After an experience covering a period o( three years with both the first ana improved " Tremain Steam Stamp Mill," in every par-
ticular I have round it perfection — a money maker, and just the thing for a small capital, while companies organized on a large soale
would do well to look into its merits.
I find no difficulty in crushing eight tons of ore per day and running on hard ore. This mill should be a winner.
Very truly yours,

GATES IRON WORKS, CHICAGO.— Gentlemen :
Our Tremain Mill is giving us good results, and although being in operation since 1892 has not cost us $1 for repairs, and to-day is
making |80 drops per minute with 95 lbs. steam pressure.
The ore we are working at present is soft and we mill in 24 hours, using No. 10 slot soreen, 15 tons.

Running Under Compressed Air in West Australia.
293 ST. GEORGE'S TERRACE, PERTH, W. A., February 6, 1900.
F. R. PERROT, ESQ , Agent op Gates Iron Works, Perth, West Australia.
Dear Sir- In reply to your enquiry as to the working of the Tremain Mill on the Burbanks Grand Junction, I would state
that at the start we worked this from the boiler supplied by the Gates Iron Works Company, but owing to certain irregularities of
the running, which were in a measure due to the intermittent supply of ore and the short time that we were able to run it per
day, I finally laid on air piping from my air compressor, a quarter of a mile distant, and used the boiler as an air receiver,
with the result that I got an absolutely constant run, which, I believe, averaged about 105 drops per minute, and this was kept up
with great regularity and showed a much better return in the treatment of the ore. The usual air pressure in this case was 80 lbs.,
whereas under steam we were not so satisfied with the result as worked at 100 lbs. By this we were also saved in cost the charges of
stoker, fuel and water, and it was worked with much greater cleanliness, and during the whole time the mill was running— which was
several months— it never froze up on us or showed any signs of trouble In that direction.
The mill is now temporarily stopped, but when it is again started I shall most deoidedly continue the use of compressed air.
Yours faithfully, _

CROWN GOLD MILLING CO
Manufacturers of the "CROWN" CONCENTRATOR and CROWN
ORE SIZER. A dry process of sizing and concentrating ore, sand or
gravel. Designed to accord fully with the laws of specific gravity,
and especially adapted to refractory ore or localities where there is
no water.
The chief claims for the Crown Concentrator are that it occupies
less floor space and has nearly four times the capacity of any wet
concentrator; that it will concentrate ores containing base and refrac-
tory metals that ordinarily slime and carry off values; that it effects
a saving of values far above the ordinary methods of concentration.

THE GRIFFIN

THREE ROLLER
7VYI
The Griffin Three Roller Ore Mill is a simp.y constructed Mill, suitable for working all kinds of ores that
require uniformly Hue crushing by the^ret process. This Mill is a modification of (he well-known Chilian
Mill, but the rollers run upon a crushing ring or die, which is Inclined inwardly at an angle of about 30 dogroes,
tho rollers themselves also being inclined to the cent nil shaft ol Hi" Mill, thus utilizing the centrifugal force,
as wi H ;is the weight of the rollers themselves as a crushing agent. The Griffin Three Boiler Ore Mill is there-
fore :t Mill *'f great strength, and has few wearing parts. We construct these Mills with extreme care, using
only the befit nf raw materials, which are most carefully worked by men who arc specialists as mill builders.
\\'e sell tlie Griffin ore Mill mi iis determined merits, and will gladly supply full information regarding it to
any one.

The Ideal Conveyor Belt
Is the one that will carry stone, ore, coal, wet or dry
material, holding buckets firmly and securely; will
stand all kinds of exposure, and resist toe heaviest
strains during a long period of service. This Is what
the LEVIATHAN BELT has done, and we quote the
following from a letter from the New York Steam Co. :
"We have used Leviathan Belting for four years, up
to Winch by ft-ply, elevating and conveying coal. Some
of the Belting is outside, exposed to freezing weather;
some In a steam bath. In both conditions the results
have been very gratifying, over 500 tons having been
handled in ten hours time."

This machine is warranted to show in actual service results hitherto unattainable with any o*her
make of injector on the market. With feed water at 75° F., LIFT 6 FEET, It will work WITHOUT
ADJUSTMENT OF STEAM OR WATER AT ALL PRESSURES FROM 40 TO 250 LBS., AND
HIGHER, AND THE CAPACITY CAN BE
GRADED OVER 50% AT ANY POINT in that
range of work. Note carefully, ALL CONDI-
TIONS ARE MENTIONED In this statement.
The construction is simple and free from all
complicated mechanism. All parts are easily
accessible and tubes are very dufable. In
grading tbe capacity, the steam supply is
cut down in proportion to the water, hence
the disoharge is cool and scale is not so liable
to form.
It is thoroughly reliable and cau be started
promptly under the mo^t extreme conditions,
and UNLIKE many others its efficiency is not
confined to any particular season of the year
The capacity increases with the pressure. A
trial is solicited and satisfaction guaranteed.

Economic and Hining Geology.
In the issue of the 11th inst., considerable space
was given to the statements of Director Walcott of
the TJ. S. Geological Survey concerning the rela-
tion of the work in which he and his assistants are
engaged to the mining industry.
In continuance of this subject, so important to
the miners of this west half of America, is given
further space to additional statements of Director
Walcott in connection with the economic and mining
geology of the U. S. Geological Survey. He desires
to define the difference between the work of the Sur-
vey and the domain of private enterprise, and to
show the status and limitations of the branch of the
public service that he directs. He says :
It is well known that in creating the United
States Geological Survey Congress and the people
whom it represents expected that its energies would
be largely devoted to the development of the mineral
resources of the country. How this method should
be accomplished was left to the Director and his
principal assistants, who, by scientific training and
long practical experience, were the best qualified to
judge what could and what could not be done by such
a corps of specialists as the Survey must necessarily
consist of — men whose whole life is devoted to the ab-
stract side of geology and whom neither the regula-
tions of the Survey as defined by law nor the ex-
igencies of their official duties would permit to par-
ticipate in the practical or commercial development
of these resources.
It was evident that these specialists could not take
the place of either the prospector or the mining en-
gineer, as a somewhat superficial view of the subject
has led some to think they might. They should, of
course, understand the principles that underlie the
work of either of these classes of men, but they can
not be expected to possess that expertness of in-
stinctive second sense in each of these professions
which can be acquired only by lifelong practice.
The Survey should furnish an accurate basis upon
which the work of each of these experts, so in-
dispensable in the development of the mineral re-
sources of the country, may be founded. The Sur-
vey stands, so to speak, between them and nature.
It should endeavor to tell the prospector where he
may and where he may not prospect to advantage for
this or that valuable mineral, but it can not be ex-
pected to actually find the mineral for him. It should
aim to discover for the mining engineer first of all
the general laws which govern the occurrence of the
different useful minerals, and to show the special ap-
plications of these laws in the particular mining
regions that come under survey ; but it can not un-
dertake to direct the workings of individual mines or
quarries, nor guarantee that every mining engineer
will make a correct application of the laws that have
been discovered.
In the early years of the Survey there were prac-
tically no topographic maps upon which the surface
distribution of different classes of rock formations
could be indicated (areal geology), and which should
thus serve as a basis for the work of the prospector.
Hence it was only the study of the already devel-
oped ore deposits, for the purpose of determining
the laws under which they were formed, that could be
immediately undertaken. A number of monographs
or exhaustive studies of important mining districts
were made, during which several new laws or gen-
eralizations concerning the formation of ore deposits
in general were formulated. Incidentally, the ac-
curate geological descriptions contained in these
monographs proved to be of great practical value to
those engaged in mining in these particular districts.
By these studies, conducted for the most part at
great depths below the surface, those engaged in
them acquired a practical familarity with many geo-
logical phenomena connected with ore deposits that
could not be seen upon the surface, and were thereby
specially fitted to judge of ore bearing capabilities of
rock formations in general. This constitutes a
special training that can not be acquired in the
schools, but can only be imparted to the young geo-
logist by actual experience in mining or economic work
under the guidance and instruction of older geo-
logists who have already gained it by long continued
special work.
During the last five years the topographic maps of
very large areas have been completed, constituting
several hundred of the sheets that will form the basis
of the Geologic Atlas of the United States. Many of
these sheets have already been colored geologically
— that is, the areal geology has been completed — and
they have been published as geologic folios. In a few
cases the areas have also been studied economically ;
that is, the manner of occurrence of the known ore
deposits has been observed, and deductions drawn
therefrom are given in the folio, which will show the
prospector where similar favorable conditions exist,
and where, in consequence, are the most promising
localities to search for other ore deposits. The latter
class of work is more difficult and more expensive,
for many reasons, than other geological work.
The increase in effectiveness of this work must,
however, proceed slowly. Even with unlimited
amounts of money immediately available the economic
work of the Survey could not at once be spread over
the whole country, as it should be, for the reason
that it would take time to train the additional num-
ber of specially prepared geologists required. But
there is no doubt that by a natural enlargement of
the present plan of work the demands of the mining
community for Government aid in the development of
their particular branch of industry can readily be
largely met.
It has been generally understood that information
acquired by the Government is open to all and is not
for the benefit of one individual or corporation. Lan-
guage to this effect was inserted in the statute organiz-
ing the Geological Survey, in 1879. This, then, draws
the line between public and private interests. There
is more or less extended desire that assays . and an-
alyses and examinations of prospects and mines
should be undertaken by the General Government ;
but it would seem to be clear that expert work and
assaying should be left to individuals and corpo-
rations, so far as General Government is concerned.
State mining bureaus or schools of mines can prop-
erly assist in the study of details and lend much aid
to local development, but the General Government
should deal only with interstate and such other prob-
lems as the State can not well undertake.
From nearly every part of the foothill and moun-
tain region of California comes the usual annual
statement that milling operations are ceasing be-
cause of the scarcity of water. The annual gold
yield of California is in exact ratio with the amount
of rain and snowfall. With adequate system of water
storage the normal supply would serve throughout
the greater part of the year. The subject is one
that has received constant and intelligent attention
but is necessarily difficult of successful solution. The
California Miners' Association has recognized the
importance of the subject and has made tentative
efforts to remedy existing evils. The recently organ-
ized State Water and Forest Association is the result
of such work, and that association has its co-opera-
tive support. In the practical carrying out of the
plans of the Water and Forest Association lies largely
the ultimate satisfactory solution of this important
problem.
The rienace of Fire.
From all parts of the mining area of the country
come reports of devastation by forest fires, entailing
loss. The deplorable destruction of private interests
is even surpassed by the direct public loss. The daily
press rightly reasons that drastic measures of re-
pression must be put in force. The miscreant who
deliberately burns his neighbor's property is no less
a destroyer than the careless idiot who drops a
cigarette in a bunch of dry grass and burns out a
whole country side. Most things are becoming fool-
proof, but as yet much is at the mercy of the itin-
erant, who, in ignorance or defiance of results, care-
lessly causes a fire to spread destructively over a
wide area. Colorado and California have suffered
great damage in this way, as have other States ; and,
while nearly every commonwealth has a law making
such occasioning of fires a penal offense, there is little
effort at enforcement. 'Tis true there should be an
era of stern repression ; a few examples are needed.
Washington, D. C, reports that a scientific in-
vestigation of forest fires and reforestation on burnt
areas is being pursued by the Division of Forestry
through C. S. Crandall of the Colorado experiment
station. This work will be carried on chiefly in the
northern part of the State, where the prevalence of
Lodgepole pine makes the conditions very different
from those in the south. The investigation is an im-
portant one, for, until the forester knows what to ex-
pect from fire and how to deal with burnt-over areas,
he can do little in a region where burning has been
as extensive and is still as common as in Colorado.
In this investigation the examination of the first
stages of reforestation will be made on areas of which
some were burned over thirteen years ago, and on
which others in government employ had already
made surveys and recorded progress at different
periods since. In the case of the old fires of which
there is no record, the date of burning can usually be
determined by the age of the trees which came up
after the fire, and the necessary surveys and meas-
urements can then be made.
Mr. Crandall will have four assistants and will be-
gin his examination in the Medicine Bow range.
From there he will work down the Continental Divide
to the neighborhood of Long's peak.
G. B. Sudworth, the dendrologist of the Division of
Forestry, is in the Sierra forest reserve of California
to determine the feasibility and cost of making a
forest working plan for the reserve. Such a work-
ing plan would be a detailed and scientific programme
for managing the reserve and harvesting its timber
crop in such a way that the forests and their pro-
ductive power would be maintained. This would
imply the careful regulation of cutting and grazing,
the adaptation of a system of protection from fire
and trespass to the needs of each locality and pro-
vision for the maintenance of the water supply in the
regions dependent on the reserve for irrigation. It
would make it possible to bring the reserve to the
point of highest usefulness under skilled and far-
sighted management. Unlike much of the reserved
land in California, a good deal of the region in the
northern part of the Sierra reserve, which is within
the range of the Bigtree and the upper limit of which
is the southern boundary of the Yosemite National
Park, is heavily timbered. A working plan would
therefore provide not so much for the production of
forest growth as for its maintenance.
Mr. Sudworth will also gather material for a re-
port on the composition and stand of timber in the
reserve and its commercial importance, the classi-
fication of the various lands and the origin, extent
and character of fires.

In the " life of a gold lode mine " enter several factors;
prominent among them are the amount of ore available,
the number and capacity of the stamps, the method of
working, the desire for dividends, the skill of the man-
ager and other considerations that necessarily render any
general calculation only approximate.
This paper will bo ploased to receive from any of its
roaders statements of work done or results accomplished,
or other matters of general interest, accompanied by
such detail and data as would make the matter plain.
Whore practicable, photos or sketches would be of addi-

From a pattern made of soft pine, put together with
nails, an iron casting will weigh about sixteen pounds
to every pound of the pattern's weight. A brass casting
will weigh eighteen pounds to each pound of the pattern's
weight. An alloy nine parts lead, two parts antimony
and one part bismuth will expand in cooling.
The extraction of 95% by tho chlorination process
from gold ore going $100 to the ton would he good result.
The ore loses about 24% of its weight in roasting and
leaching. Tailings in the case would assay about $6 per
ton, and for every 100 tons of ore treated there would be
about 70 tons tailings, containing about $456, gold.
To prepare proof gold, dissolve several ounces
fine gold in nitro-muriatic acid ; allow to stand several
days, that any silver chloride present may settle; filter
the solution ; evaporate to crystallization. After dilut-
ing copiously with distilled water place the solution in a
receptacle, from which it is allowed to pour slowly into a
glass jar containing several small pieces of pure aluminum;
the gold is at once converted from chloride to metallic ;
considerable heat is generated ; remove the larger pieces
of aluminum, pour off the solution ; wash the gold pre-
cipitate several times to remove any acid. Then add
muriatic acid and heat to dissolve any minute particles
of aluminum, after which wash well till free from add i
thon dry and melt the gold, which should be pine
fine if proper care has been exercised.

CaKBOLITE, from which el liylei D rival of acetyleno,
is genorated, is made from slag at Hammond, Ind.
Tho process of converting the slag into a white metallic
substance of twice the weight of gold is by impregnating
the molten slag with pulverized eoko and then subject-
ing the mixture to an electrical process wherebj the
whole is fused. It is claimed that each pound of the
product will produces feet of the gas, each foot equal to
15 of coal or water gas in illuminating power.
Under ordinary conditions of use, superheated steam
is saturated steam to which heat has been added without
raising its pressure, but, under the samo conditions, the
volume is Increased, if saturated steam is confined in a
separate vessel from that in which it was genorated, and
more heat applied, it becomes superheated, and as it can
not inereaso in volume under these conditions its pres-
sure is increased. Tho dearer the fuel the more incent-
ive there is to use superheated steam. Where fuel is
very costly it is economical to use superheated steam.
The air consumed by a given compressed air engine
may be calculated from the volume, pressure and tem-
perature at cut-off or release, and the volume, tempera-
ture and pressure at compression, in the same way that
the indicated consumption of a steam engine is calcu-
lated ; but in this case the indicated and actual consump-
tion should be the same, since there is no change of state
of the working fluid. Since the intrinsic energy of a gas
is a function of the temperature only, the temperature
will not be changed by loss of pressure in the valves and
passages, and the air at cut-off will be cooler than in the
supply pipe, only on account of the chilling action of the
cylinder during the admission, which cannot be ener-
getic when the air is dry, and probably is not very im-
portant when the air is saturated.
When zinc is melted with argentiferous lead in order
to remove the silver from the lead by the production of
a zinc-silver alloy, considerable loss of zinc and silver
occurs, owing to the oxidation of the former. In the
Rossler— Edelmann process this is avoided by adding \%
aluminum to the melt. Tho aluminum combines with
the oxygen present as oxides of the other metals, and
the separation of the fused mass into two layers is more
effectual owing to the greater fluidity of the melt. The
temperature of the mass before the addition of the alu-
minum should be 500° C. The alloy of zinc and silver
obtained in this way can contain up to 20% of the latter
metal. It is cast into anode plates of suitable form, and
these are used in an electrolyte of dilute sulphuric acid
containing zinc sulphate. The zinc of the anode is dis-
solved and redeposited at the cathode, while the silver
and tho small quantity of lead present remain as an in-
soluble sludge upon the bottom of the vat.
Steam is superheated to 480° F., and in exceptional
cases to 570° F. As used in common practice, steam car-
ries with it more or less water in the form of small
globules. Even the best boilers deliver steam containing
from 2% to 5% of water. If this saturated steam be
heated, superheated steam is formod, which acts after a
certain increase in temperature exactly like a perfect
gas. If this increase of temperature is carried on under
constant pressure, the temperature of the steam rises,
and its volume increases. Saturated steam of ninety
pounds per square inch of pressure, superheated to 424°
F., increases its volume one-third. This increase of vol-
ume means a less amount of steam for a certain cut-off.
Superheated steam has a high elasticity, and can there-
fore be carried at a great velocity through tho pipes. A
velocity of 400 feet is not unusual. Smaller pipes can be
used to carry the same amount of steam, and these small
pipes give less loss of heat through radiation than larger
ones would give.
Answering Colorado, Utah, Idaho and Arizona in-
quiries as to the 16 to 1 in the Kansas City platform: by
the mint act of 1834 every owner of gold bullion and of sil-
ver bullion was permitted to take it to the mint and have
it coined free of expense, except for refiniug and for alloy
used, at the rate of sixteen times as many dollars for a
given weight of gold as for a given weight of silver.
While 23.22 grains went to the doflar in gold, 371J grains
of pure silver were required for a silver dollar. With
the alloy added it took 25.8 grains of standard gold for
the dollar in gold, and 412-1 grains of standard silver for
the silver dollar, or about 16 to 1 by weight. The provi-
sion of this law as to silver was repealed in 1873. This is
what the ratio of 16 to 1 means. A gold dollar weighs
25.8 grains, of which 23.22 grains are pure gold, the re-
mainder being alloy. A silver dollar weighs 412.5 grains,
of which nine-tenths, or 371.25 grains are pure silver, the
remainder being alloy. Thus the pure silver in a silver
dollar weighs about sixteen times as much as the pure
gold in a gold dollar, and this is the meaning of "16 tol."
The proposal to adopt the free coinage of silver at a
ratio of 16 to 1 is a proposal that any owner of silver
bullion shall be authorized by law to take it to a United
States mint and have coined and returned to him $1 for
each 371.26 grains of silver, this dollar to be legal tender
for the payment of all debts, public or private. The sil-
ver in such a dollar (and the dollar itself under free
coinage) would bo worth, at the present price of silver,
JO cents in gold.
A simple and rapid way of testing a dynamo to deter-
mine whether any changes in tho efficiency have oc-
after a period of running consists in uncoupling
the dynamo from the engine and running it as a motor,
em-pose being taken from the bus bars
or from another machine until its speed of revolution
ached a given value, when the current is broken
and at the same instant a stop watch started, and the
time which the machine takes in gradually coming to
iicd. A standard may be obtained by making the
test when the machine is new or when it is known to
bo working at its highest efficiency, and then at any
ether time the dynamo may be tested for comparison
with the standard. Such tests will show whethor the
bearings are in food order or not, whether the brush
friction has become abnormal and with the fields ex-
cited, and also what the fouealt losses are, for under this
condition the armature will come to rest sooner than with
Id open, since the fouealt current losses will then
be added to tho friction losses in bringing it to rest. This
method aims only to show the relative efficiency of the
dynamo, as it would be necessary to know the moment
of inertia of the armature to determine the actual value
by such methods.
Gold and silver refining by electrolytic methods is
carried on at three works in Europe, two being in Ger-
many and one in Belgium. At Frankfort the Moebius
process is used for refining silver on a large scale. This
process is also used at St. Louis, at Perth Amboy and at
Pittsburg, in the United States. The plant at Frank-
fort is designed for an output of 35,000 ounces of silver
per day of twenty-four hours. A 25 H. P. gas engine
drives a dynamo yielding 150 amperes at 100 volts. This
current is passed through sixty to seventy cells in series,
each requiring about one and one-half volts. The vats
are of pine, coated internally with tar ; each vat is
divided into seven compartments. In these are hung
three rows of anode plates and four rows of cathode
plates. The former are plates of bullion .40 inch thick,
each weighing 3.3 pounds. The latter are thin sheets of
rolled silver. The anodes are enclosed in linen bags.
The electrolyte consists of a copper nitrate solution, con-
taining one-eighth of silver, and during the electrolysis
it is kept slightly acid by addition of nitric acid. To
prevent short-circuiting the crystals of silver are con-
tinuously removed from the sheet silver cathodes and
are allowed to collect upon a canvas tray suspended be-
neath the electrodes. They are withdrawn, washed,
dried and fused at intervals to obtain ingots of fine silver.
The rotary booster is a machine consisting of two dy-
namo electric machines, one of which is a motor which
may be either alternating or direct current, directly
coupled or belted to a generator either alternating or
direct current or arc. This machine is for use on long-
distance feeders in railway and central station work.
The generator end of the machine is series wound, and
through it passes all the current which goes through the
feeder to which it is attached. It is a low voltage ma-
chine and increases the voltage on the feeder to which it
is attached a sufficient amount to enable current to be
delivered at the end of a long feeder at the same pressure
that it is delivered at the ends of shorter feeders con-
nected with the system. It is a device to save copper;
but when it is used, the line loss is increased, though,
under conditions where for short periods of the day the
load is heavy, it pays to do this instead of adding the
requisite amount of copper. It is used in stations operat-
ing storage batteries for increasing the potential when
charging. The efficiency of such a machine is from 80%
to 85%. A static booster is practically a transformer
and is intended to be upon the long feeders of alternating
systems. It performs the same function that the rotary
booster does, by raising the pressure of the long feeder
to a higher potential, so as to make the current delivered
of the proper potential. It has an efficiency of 90%
to 97%.
An adverse mining claim must be filed with the regis-

San Francisco's Water Supply.
The city of San Francisco, Cal., daily consumes
30,000,000 gallons of water, or about eighty-six gal-
lons per day for each inhabitant. When the early
Spanish authorities were sent to select a site for a
city on the bay of San Francisco they rejected the
peninsula on which San Francisco is now built, as it
lacked water, or facilities for securing adequate sup-
ply. From the days when water was taken from
wells, hauled about the streets and distributed for
twenty-five cents a bucket, to the present system of
supply there is a long record of effort to furnish good
water in sufficient quantity at a low price. The effort
has been successful, and at an estimated cost of $30,-

which corporation supplies San Francisco with whole-
some water, figure that they now have sufficient
resources to supply more than a million people.
The conditions are peculiar. In San Francisco il
may rain a little between the months of November
and May. It is not at all likely to rain between May
and November. During the six months specified 22
inohes of rain may fall. This with six months' annual
absence of rainfall, and with occasionally only 10
inches of rainfall in the time when rain is likely to fall
at all, with no natural reservoirs, and in a billy city,
surrounded on all sides by deep salt water, the prob-
lem of water supply alforded unusual difficulty.
The city of San Francisco is built on a peninsula
pushed northward from an outlying spur of the
coast range, the area about that of Manhattan
island, on which New York city is built, the contour
varying from sea level to a height of 900 [eet. It is
a city of hills and valleys, like the country to the
southward. In the adjacent country, about 'J.'i miles
south of the Golden Gate, artificial lakes and storage
reservoirs have been created and are maintained,
from which water is piped to distributing reservoirs
in the city having an aggregate capacity of about
200,000,0(10 gallons. From these reservoirs the water
flows by gravity at a pressure of from thirty-five to
seventy-five pounds per square inch at the hydrants,
of which scattered throughout the city are nearly
4000. There are about 875 miles of water pipe.
Among the reservoirs Crystal Springs lake de-
serves especial notice. It is in San Mateo county, 28
miles from San Francisco, and is the largest of the
reservoirs. It is at an elevation of 350 feet, is
formed by a great concrete dam, which impounds about
28,000,000,000 gallons. Herewith are illustrated
some of the details of the Crystal Springs reservoir,
the building of which is conceded by engineers to em-
body some of the best and safest principles of dam
construction. It is believed to be the largest con-
crete dam in the world, and the highest dam in the

United States. It is noted no less for its magnitude
than for the originality of much of its construction.
The dam is 145 feet' high and is to be raised to
the height of 170 feet. It is 176 feet thick at the
base ; at its summit it is 700 feet long, 40 feet thick ;
its front slope is 1 foot horizontal to 4 feet vertical ;
the rear slope begins 1 foot vertical to 1 horizontal,
and ends in the upper 00 feet with a 2-foot slope
vertical to 1 foot horizontal, the two rear slopes con-
nected by a curve of 298 feet radius ; the convex side
of the dam facing upstream being curved with a
radius of 637 feet.
In building the dam the site for the foundation was
cut down from the surface for a depth of from 10 to
40 feet. No explosives were used, lest the bedrock
be cracked. The bottom being ready, blocks of con-
crete were made, each 40x30x8 feet, and when ready
were laid and dovetailed, as shown in the illustra-
tion. About 5000 of these blocks of varying size were
thus used, no two blocks being of just the same shape
or dimensions. Thus this dam is not a homogeneous
mass of concrete, but is built of interlocking blocks,
thus providing an elasticity that aids in withstanding
the pressure of the artificial lake, nearly 0 miles in
length, it. creates— a pressure estimated to be 130,000
tons against its face. The concrete used was in the
proportion of two pounds specially prepared sand to
one of cement and six barrels of rock. In the con-
struction were consumed 1,230,000 barrels of rock,
410,000 barrels sand and 205,000 barrels Portland
cement. The dam was built far into the solid rock
on each side of the canyon, to insure greater security.

The water from the San Andreas reservoir flows
under a 340-foot pressure, through a 30-inch pipe, 16
miles, and at the College Hill reservoir is subjected

of that new industry.
Like other commercially scientific subjects, the
carborundum industry is a progressive one, and some
of what in 1896 was up-to-date is in 1900 becoming

Cables is explained as follows: Sleeves of soft cop-
per, long enough to receive the two cable ends for a
distance of about twice their diameter, are provided,
the walls of the sleeves being sufficiently thick so that
the sleeve contains as much metal to the' running
inch as the cable, or more. The two ends are butted
in the sleeve, and the jaws of a hydraulic press of
considerable power, but light weight and small size,
are set on the joint. One squeeze at a pressure of
about forty tons to the square inch welds the sleeve
and the cable into a solid mass, so that if the joint is
sawed apart it is impossible to tell where the metal
of the sleeve ends and that of the cable begins.

obsolescent. When the article referred to was writ-
ten, the crude materials for the manufacture of car-
borundum at Niagara Falls were sand, coke, sawdust
and salt. These were ready for use except the coke,
which had to be ground to a fine powder. The fur-
naces were built of brick and had the form of an ob-
long box about 16 feet in length and 5 feet in width
and depth. In the center of either end were the
terminals, consisting of sixty carbon rods 30 inches
long and 3 inches in diameter. The mixture was
thrown into the furnace, connection made with the
dynamo, and after twenty-four hours the process was
complete. The carborundum occurred in the center
of the mixture as bright, radiating crystals. In order
to prepare the carborundum for the market, it was
first placed under heavy iron rolls for the purpose of
crushing apart and separating the individual crystals,
which were then washed in a solution of acid and
water to remove solubles,. and finally dried and sifted
to separate the different-sized crystals. During the
year 1896 the Carborundum Company produced in
round numbers 1,191,000 pounds of crystalline car-
borundum, used chiefly, as an abrasive, for which it is
well suited, owing to its excessive hardness.
The first manufacture of carborundum for commer-
cial uses was on so small a scale as to make it prac
tically a laboratory product. The carborundum so
produced was at such a high cost that its commercial
usage was restricted to very limited lines. The first
sales of carborundum were made to lapidaries, to be
used in the place of diamond powder, and the price
ranged from $400 to $600 per pound. This was in
1892. Later in the same year the scale of manufac-
ture was so increased that an average of one-quarter
of a pound per day was produced, and as this amount
was found to be in excess of the capacity of the lapi-
daries to absorb, attempts were made to introduce
the use of carborundum into other lines, and consid-
erable quantities were sold to brass manufacturers
for valve grinding at prices which varied from $15
per pound down to $2 per pound in 1893.
In 1894 the Carborundum Company commenced the
manufacture of carborundum on a really commercial
scale by the use of an electrical current of 150 H. P.,
which gave a production of 100,000 pounds of car-
borundum per year ; in 1895 the company built its
factory at Niagara Falls, and in 1896 commenced the
use of 1000 electrical H. P. In 1899 this was in-
creased to 2000 H. P.; the production of carborundum
for that year amounted to 1,742,000 pounds. On
Jan. 1, 1900, the company had in operation fourteen
furnaces.
The scale and the character of the sale of car-
borundum has changed from a measurement by the
carat at $600 per pound in 1892 to the measurement
by the carload at 10 cents per pound in 1899. The
total sales of carborundum in 1899 amounted to
2,018,000 pounds.
The illustrations on the front page show the latest
progress that has been made in the carborundum
manufacture, and comparison of them with those
published in January, 1896, would exemplify the ratio
of progress.
Besides the varied commercial uses of carborundum
it is now becoming of interest to metallurgists in
other fields, notably in its substitution for ferro-
silicon in steel manufacture. The composition of
ferro-silicon averages 15% silicon ; commercial ear-
bide of silicon averages 62%. The carbide of silicon
is in the form of grains or powder, and, on account
of its chemical nature, is readily taken up by the
molten steel, so that in actual practice it is now cus-
tomary to merely put the necessary amount of the
carbide into paper bags and throw the latter into the
ladle, which is then filled with the molten steel. The
object of adding silicon to steel is to increase the
fluidity of the metal while in the molten state, this
being occasioned by the increased temperature pro-
duced. In the use of ferro-silicon a certain propor-
tion of heat becomes latent or is absorbed in ef-
fecting its decomposition when added to steel : this
meaning so much heat lost. Carbide of silicon is an
endothermic compound, giving out heat during decom-
position.
So far as known, carborundum does not occur in
nature, probably because the temperatures of forma-
tion and decomposition lie so close together. Car-
borundum is insoluble in water or any acid ; it ap-
proximates the diamond in hardness, and is fast com-
ing into general use as an abrasive.

The Copper Queen nine, Arizona.*
Edward Keller, Baltimore, Md., in a communica-
tion to the secretary, says: When, at the New York
meeting, February, 1899, Mr. Douglas gave an ab-
stract of his highly interesting paper on the Copper
Queen mine, he invited the members of the Institute,
in his usual progressive spirit, to make a full scien-
tific investigation of the region of that mine during
the prospective excursion to Bisbee, Arizona. I vol-
unteered to examine some of the metallurgical pro-
cesses and products of the works, and obtained from
Mr. Douglas a valuable series of samples. Upon the
issue of his paper, however, I found that he had
already a considerable volume of analyses of those
products, and that little was left for me to do in that
respect, except to duplicate his results, the import-
ance of which work would not have been commensu-
rate to the time and labor involved. I selected,
therefore, only some points which he had not made
entirely clear, or concerning which I was skeptical.
The details of most of my work will appear in a
future paper.
From Mr. Douglas' figures I have calculated the
values for the elimination of impurities in the so-
called Leghorn converter, introduced by him at the
Copper Queen works, and have found them to be as
follows :
PERCENTAGE OF ELIMINATION OP IMPURITIES IN

Av.99.2 99.6 93.8 93.1 96.2 73.1 79.5 35.0
Those elements for which I have determined the
elimination in other converters, and which also ap-
pear in the above table, are lead, antimony, arsenic,
selenium and tellurium. Mr. Douglas' results as to
these show no new feature ; they closely corroborate
my own, as given in a former paper, t Selenium and
tellurium, in Mr. Douglas' case, as well as in my own
heretofore, were determined jointly. As the Copper
Queen mattes contain a greater amount of both
elements than the mattes which I had previously ana-
lyzed, I now took occasion to separate the two, and
found the elimination of selenium to be somewhat
greater than that of tellurium. To sulphur, iron and
zinc I paid no attention in my former publications,
because I always considered them as members of a
group of elements of which 99% or more is eliminated
in the converter. In fact, I have been unable to find
zinc in the copper of the Copper Queen or in any
other converter copper.
Mr. Douglas gives to nickel as high a figure for
elimination as to zinc. Since zinc is a far more oxidiz-
able and volatile metal than nickel, I thought there
was good reason to doubt the correctness of this con-
clusion. In the course of analysis, unless a separation
of nickel and cobalt be attempted, the two elements
would naturally be determined together. In the Cop-
per Queen mattes I found that, of the sum of the two
metals, from one-fourth to one-half is cobalt ; and as
the latter (being practically all eliminated in the con-
verter process) could not be found in the copper, I
found the elimination of nickel to be much below Mr.
Douglas' figure. The cobalt, on the other hand,
must now be placed in the same category as sulphur,
iron and zinc.
I subjoin an analysis of a Copper Queen matte as
being, perhaps, of some mineralogical interest. The
figures are not derived from one sample, but culled
from half a dozen :
COMPOSITION OF COPPER QUEEN MATTE.

Ag. Au.
Ozs. per ton.. 6.0 0.10
As compared with the mattes of Butte City, Mont,
(see my paper already referred to), it will be seen
that the Arizona matte is lower in gold, silver and
bismuth, but higher in selenium and tellurium. This
I mention because it is my impression that all
these elements are generally supposed to be associ-
ated.
On mathematical grounds one might expect that
with increase in the capacity of a converter there
would be an increased economy in the wear of the
converter lining, the surface of the matte in contact
with the lining increasing at a " square " rate, while
the mass of the same matte increases at a " cubic ' '
rate. In the case of Mr. Douglas' slags their acid-

ity, in fact, decreases in each succeeding blow, as
will be seen by his figures :
ACIDITY OF CONVERTER SLAGS.

First blow 36. 78 34.64
Second blow 35.30 33.46
Third blow 34.35 32.60
Fourth blow 32.57
Mr. Douglas does not give the weight of the matte
charged or of the copper produced. Only the num-
ber of copper bars are given, as follows :
First Second Third Fourth
blow. blow. blow. blow.
Number bars. . . 9.5 14.5 14.5 12
It may be assumed that the weight of matte or
copper was proportional to the number of copper
bars, in which case there was no regular increase in
the capacity of the converter. The mathematical
theory, therefore, does not apply in this case. Per-
haps the real reason for the reduced acidity of the
slags in successive blows is found merely in the physi-
cal condition of the lining, which may have become
more and more compact by continued heating.
The Anaconda Converter.
When approaching Anaconda by the B., A. & P.
Railroad, almost the first object in connection with
the reduction works to attract the eye is a huge
pyramidal pile just below the converter. It is nearly
black in color, and extending up the elongated west-
ern slope is what appears to be a railroad track. In-
vestigation discloses the fact that this conspicuous
object is composed of granulated slag from the blast
furnaces of the converter. This slag is drawn off from
the furnaces in a molten state. It is run into a sluice
carrying a strong stream of water, which cools and
granulates it. Passing down the surface a couple of
hundred feet, it is deposited into two large receiving
tanks. These tanks are elevated on piling, so that
small cars or skips can pass under them. In the
bottom of the tanks are doors through which the cars
are loaded, and then by means of a stationary engine
they are hauled to the top of the pile referred to and
dumped. Inquiry at the converter will bring out the
fact that this huge pile has all been formed within the
last five or six months. When it is considered that
it has all come from the six blast furnaces, and con-
stitutes but a small fraction of the ore treated at
these works, it is faintly suggestive of the magnitude
of their operations, and also of the tremendous quan-
tities of ore that are taken from the Anaconda
mines at Butte. This method of disposing of the
slag from the blast furnaces is made necessary by the
nature of the ground, the fall not being sufficient to
carry it away by mere gravity.
The converter is always a busy place, as may read-
ily be imagined from the fact that it turns out an
average of about 12,000,000 pounds of metallic copper
each month. This is partly in the form of pig copper,
which is sent East for refining, and partly in anode
plates, which go to the refinery here.
The regular work of converting has been broken in
upon during the last few days by the cleaning of the
flues. About once in two months this is done. The
quantity of flue dust saved is large, and very high in
copper, that from the converters running from 20%
to 50%.
An improvement just made of some importance is
in the method of lining the converters. For this pur-
pose the material heretofore used was ground silica,
reduced to the consistency of thick mud, the work of
lining being done entirely by hand. By the new
method, slimes from the concentrators are used, and
these are tamped into the converters by tamping
machines. A small quantity of silica is mixed with
the slimes to give them consistency and aid in the
tamping process. A square pit has been prepared
at the west end of the converter, equipped with three
of these tamping machines, which are run by com-
pressed air. Into this pit the converters are lowered
by the electric crane and placed under the tamper.
Being thus placed, it is connected with shafting
whereby it is turned slowly round and round, each
revolution bringing in the entire circle under the
tamping bar.
There are two primary objects in lining the con-
verters. One is to preserve them from the effects of
the intense heat, and the second is to furnish an in-
creased quantity of oxygen to keep alive and
strengthen the combustion. Silica has heretofore
been used, because it consists largely of oxygen; but
the slimes also are composed to a large extent of
that same gas, and hence. will serve the same pur-
pose. Besides this, the slimes contain a certain per-
centage of copper and other values, the most of
which are saved by the process of converting. This
is literally killing two birds with one stone. It is said
that about 125 tons of slimes are used each day for
this purpose, and the quantity of copper thus saved
is an item well worth considering.
It is very evident that in the onward march of im-
provement at the works the converter is not to be
left out of the line of march. — Anaconda, Mont.,

cuit, three of the strands being removed to afford air
space within the cable. The current used was .from
120 to 135 amperes, the voltage at the machine being
varied from 80 to 115. After the wire became heated
it was pulled back and forth like a crosscut saw, and

Uranium and Its Ores.
WrltleD for tbe Mining a.ni> SVlBNTliric Phiss by DK. J. Only. -
The metal uranium tin 1782 by the obem-
ial Klaprotb and named by him thus From the planet
Uranus, has a steel-gray color and a specific gravity
■ if !>.". approaching closely that of gold, which is
19.8. Like many of the rani- metals its isolation in
iiemieally pure condition is combined with con-
siderable difficulty, so that its utilization as such has
not reached any degree of prominence. It is mainly
for this reason that the tendency of modern engineer-
ing leans toward the production of alloys of the rare
metals instead of the metals themselves, a circum-
stance which has led to the development of a peculiar
industry aiming at the manufacture of a great num-
ber of metallic alloys, among which the undetermined
compounds of uranium and steel play a significant
role Es| ially in France, the beneficial effect pro-
duced by the addition of a small percentage of ura-
nium carbide to steel has been realized, so that an ex-
tended manufacture of war material from that alloy
has sprung up there in the last two years. It seems
that a compound of this kind surpasses any other
product obtained by mixing and incorporating ferro
or carbon alloys with fluid steel, as it increases the
tensile strength, toughness and elongation of that
substance remarkably. Hence the demand for ura-
nium ores has materially increased in later years.
The application of uranium derivatives, is, how-
iiot limited to this industry alone, but extends
into several other branches of manufacture. Thus
two of the uranium oxi.les U,< i. and U30„, the lat-
ter corresponding in composition to the compound oe-
curring in nature as the ore pitchblende, are prized
as a means for producing a pure intense black glaze
on porcelain. A hydrated sodium uranate, known in
trade as uranium yellow, and a hydrated ammonium
uranate, serve for the manufacture of a brilliantly
fluorescent uranium glass, possessing the peculiar
property of arresting chemically active rays, and
also as permanent colors in the decoration of glass
and ohinaware.
The first of these oxides is best prepared by
strongly igniting uranium nitrate, when a black pow-
der results, which may be utilized immediately after
cooling. The second compound remains on heating
the black oxide at a moderate heat in air or oxygen,
but is generally produced by igniting uranium nitrate
or ammonium uranate at a gentle heat, not sufficient
to reduce it to the lower oxide U2On. Finally a
sodium salt is obtained by adding an excess of sodium
hydrate to the solution of a uranium salt, but prefer-
ably by fusing uranic oxide with sodium carbonate.
On the large scale, a mixture of 100 parts of pitch-
blende, containing about 45% of U308, and 14 parts of
lime is roasted in a reverberatory furnace, the calcium
uranate formed decomposed by the addition of dilute
sulphuric acid, and the solution of uranic sulphate
thus obtained mixed with an excess of sodium car-
bonate, whereby the metals present are precipitated,
while the uranium enters into solution. After boiling
and filtering, the clear filtrate is just neutralized
with dilute sulphuric acid and heated, when a finely
divided sodium uranate of the formula Na2U2 .6H20
separates out. The ammonium uranate, on the other
hand, is obtained by adding ammonium chloride or
sulphate to a boiling solution of sodium uranate, and
forms, when dried and gently heated, the fifth com-
mercial uranium compound mentioned.
Of the several uranium ores occurring in nature
only two deserve special consideration, namely, pitch-
blende and carnotite. as these ores are known to oc-
cur in quantities in the territory of the United States
sufficient to answer the purposes of commercial ex-
ploitation. The former ore is mostly encountered in
the form of pockety formations, while the latter is
found in fissures, sometimes over 2 feet in thickness,
or in blanket formations breaking through the ad-
joining rock of sandstone deposits, sandstone cliffs or
decomposed silicates. Both of these minerals are
readily recognized by their appearances and specific
gravity, since pitchblende is velvet-black in color,
when unaltered, and, when partly decomposed on the
surface, of a brownish or grayish tint. Its luster is
sub-metallic or dull, and its streak black, while its
specific gravity reaches the figure 9.2 and 9.3, so
that the mineral can be readily distinguished by its
weight or heft. It is composed of a mixture of ura-
nous and uranic oxides — U02 ,2U03 or U3Og —
chemically speaking, with casual admixtures of small
percentages of lead and iron, and is of special inter-
est to the scientist, since it gives off, on heating with
sulphuric acid, several rare and newly discovered ele-
ments, among them radium and polonium, two radio-
active substances.
The second uranium ore of importance, carnotite,
has been discovered but recently, and been named
thus from the French scientist, Carnot, who first as-
certained its composition and was especially instru-
mental in bringing it to prominence. It is of slight
reddish-yellow color, hence easily distinguished,
crumbles readily into powder, and leaves traces
wherever placed or whenever touched, as it is very
soft and brittle, when pure. The ore varies in con-
tents of uranic oxide from 52% to 15% or less, and
carries values of vanadium peutoxide in quantities of
: own to 4"„. being mainly a hydrous potassium
uranium vanadate, as becomes apparent from the fol-
lowing analyses :

showing that the silica predominates in some of these
ores to a marked degree, and that they were presum-
ably produced by infiltration and subsequent oxida-
tion.
These ores are of extraordinary value on account
of the presence of the two rare metals, uranium and
vanadium, the former being quoted in the New York
market at $10 per unit and vanadium pentoxide, usu-
ally called vanadic acid, at $9 per pound. They are
separated from accompanying impurities and gangue
by mechanical means, then concentrated by a chemi-
cal process and shipped in the form of oxides to New
York and thence to English, French and German
ports.
Though the analyses given above show the presence
of both uranium and vanadium in the ore, this is not
always the case, since the writer had occasion re-
cently to analyze an ore of this class of alight canary
yellow color which he considered as identical with
carnotite in the beginning, but which on careful re-
search showed the complete absence of uranium com-
pounds and was finally recognized as a pure vana-
date. Vanadium compounds being still more valuable
than those of uranium, and the market for them hav-
ing been widened by modern inventions in Germany,
England and France, the discovery was by no means
a disappointing one, and is expected to lead to inter-
esting researches and remunerative speculation.
The country contiguous to the Paradox valley,
Montrose county, Colorado, in which the carnotite
deposits described above are found, consists of appar-
ently barren cliffs and its most mineralized section
lies between that valley and the San Miguel river to |
the north. A recent shipment of a carload of uranium
ore from this part of Montrose county brought the
sum of $3580, representing the net profit on the lot,
after deduction of mining and transportation ex-
penses. Several small lots which were sent to Den-
ver to be tested gave returns varying in value from
$200 to $1600 per ton, the former figure showing the
average price offered by the State sampling works
for the material. These ores, when mined, contain as
a rule from 8% to 10% metallic uranium and their
market price increases with the relative degree of
concentration.
The recent discovery of a pure vanadate, as indi-
cated above, occurred in a quite different part of the
State and is of material importance, since the metal
vanadium and its compounds have come prominently
to the front during the last two years by the re-
searches of several chemists, among them S. O.
Cowper-Coles, who succeeded in producing metallic
vanadium of a silver-white color by the electrolytic
process. While the fusing point of the metal uranium
lies near 1500° C, that of vanadium approaches 2000°
C, a circumstance which has induced German manu-
facturers to utilize vanadium together with zirconium
and thorium in the production of gas mantles and
similar articles. The fact has also been established
that a limited addition of vanadium carbide to fluid
steel improves the tensile strength and ductility of
that substance, while copper and aluminum are af-
fected in a similar manner.
The usefulness of vanadium and its compounds is
further exemplified by the application of the latter in
dyeing silk, and printing calico, and by the forcible
effect of diminutive amounts of them in the conversion
of aniline colors into fixed dyes for indelible inks.
Samples of the ore containing the vanadate, which
yet remains to be named, will be submitted to the
Smithsonian Institute and the Government chemists
for examination and analysis, and the results ob-
tained will be reported in time. A comparatively in-
expensive method having been established for the
separation of uranium from vanadium compounds and
the production of the oxides of the two metals on a
commercial scale, it is expected that these conditions
will induce renewed efforts in locating deposits of this
class, the more so as these possibilities are enhanced
by the characteristic properties of the minerals and
the high market price maintained for them through-
out the civilized world.
A Cooling Tower.
At the Center Star mine, Rossland, B. O, the new
forty-drill compressor, which has lately been in-
stalled on this property, is worked by steam power,
and water in considerable quantity is needed. The
compression of the air sets free the latent heat con-
tained in the greater volume uncompressed and its
being stored in the lesser compressed volume heats
it, and by its presence tends to work against the
power used to compressation by expansion.
The air in the low-pressure cylinder is compressed
about twenty-five pounds. The low-pressure cylinder
is a double one, the outer being a water jacket, and
between the two a constant circulation of cool water
is passed through, which, condensing the air in vol-
ume, allows of the utmost compression commensurate
with the power exercised. Hence the compressed
air passes into an intercooler, which is also the means
of communication between the high and low pressure
cylinders. This intercooler is filled with a mass of
pipes, through which flows a constant stream of cold
water. The partially compressed air then enters
the high-pressure cylinder, where a greater force of
compression — expressed by eighty-five pounds in
practice — is used. After this it enters the main pipe,
leading the air to wherever it is needed. In the
high-pressure cylinder, as in the low-pressure, a
water jacket is placed.
With the system of water jackets and intercdoler
pipes a great quantity of water has to be used. In
addition, the water used must be cold. The steam
also uses a quantity of water; and if the exhaust
steam is allowed to pass off, much water will have to
be brought to the machinery. The exhaust steam is,
however, passed through a condenser, which dis-
charges warm water into a pipe which, running
round the outside of the building, takes up the dis-
charge from the water jackets and intercooler and is
pumped up to the top of the cooling tower. Here,
after being cooled, it is run into a tank situated
under the floor of the compressor room and thence is
pumped into the water jackets, intercooler, etc.,
completing the circulation. A certain amount is lost
through evaporation and other subsidiary causes,
and this loss is made up by a stream of water flow-
ing through a small pipe from outside sources into
the tank. The pipe would have to be of considerably
larger dimensions were the cooling tower cut out of
the circulation. The pump forcing the water from
the tank through the circulation system takes its
supply from the upper part of the reservoir, so as to
allow of sediment to drop to the bottom. This in
turn can be blown off by means of an outlet below.
The double cooling tower is about 40 feet in height,
36 feet in length and 6 feet in breadth, divided longi-
tudinally by a rough boarding rising to the top of the
tower. The water, being pumped up to the summit
of the erection, flows along each side of the top in

two pipes, which discharge through eight valves into
troughs to the right and left. Over the beveled
edges of these troughs the water runs over and drops
onto the sides of the tower, filled in by a series of
smoothed boards set at an angle of 45°; resembling a
Venetian blind. Each shutter is 6 inches broad. At
its lower edge a metal strip, turned up along its
front, catches the dripping water and directs it to
the back, where it drops onto the next shutter 6
inches below. The inner edge of this shutter is about
on a level with the outer edge of the shutter above.
This process is repeated thirty-five times, when the
water, thoroughly cooled by its passage in, drops
through the air and reaches the metal-sheeted floor,
where it is held to run over at the lower end of the
floor, which is set at a slight angle, into a pipe which
feeds the tank under the compressor room. The
longitudinal division of the tower converts each side
into a chimney, and a constant updraught of air is
thus mechanically obtained. — Rossland Miner.
Silver Smelting in Mexico.

The following are examples of silver ore beds :

VIII 73.4 3.5 6.8 1.5 2.3 30.0 ..
No. VI is the type of a low-grade silver ore, valu-
able on account of the large percentage of lime it
contains.
No. VII is the type of a high-grade silver ore with
the same characteristic as the former.
No. VIII is the type of an ore which was used as
siliceous flux in matte concentration. Such ores as
that can only be procured at special rates, as the de-
duction for excess of silica and the treatment charge
would prohibit their shipment to a smelter. If at all
suitable, they can be treated cheaper by the patio
process, which costs $13.45 per ton, and yields from
93% to 94% of silver.
The following are examples of Angangueo ore from
the Michoacan Railway & Mining Co., successors to
Las Trojes Co. :

X...14.3 37.9 0.9 5.6 .. 6.2 1.0 35.9 6
No. IX is the coarse ore (gabarro) from the An-
gangueo mines. Wood being plentiful and cheap in
that part of the country, the ore was roasted in
heaps at San Marcial at a cost, it is claimed, of $1 a
ton. This ore did not fit in very well with the ores
treated at smelter No. 3, and was therefore not fre-
quently put on the furnace charge, but when it was
used in large quantities it made the furnaces run
very fast. This caused, however, other inconveni-
ences of a serious nature, counterbalancing the gain
by increased tonnage, of which I shall speak later on.
No. X was the fines or tierras from the same
mines. They were calcined in the long-hearth fur-
naces of the smelter, but the sulphur was not reduced
to the proper point, owing to the insufficient dura-
tion (twenty-four hours) of the roasting operation.
The roasted tierras have just the contrary effect
upon the speed with which the charges descend in
the blast furnace ; they reduce the tonnage by fully
one-third of the normal, and act badly otherwise.
While a furnace 42 X 120 inches will take ninety
charges of 1000 pounds in twelve hours with the
gabarro on, it will only take fifty charges with the
tierras on, the normal speed being seventy-five
charges.
The tierras should be bricked in a machine prior to
being put into the smelting furnace. Another mean
product received from Angangueo was matte made
from the ores there in a water-jacket cupola. This
matte contained neither lead nor copper, but 70% of
iron, 6% to 9% of zinc, and thirty-five ounces silver
per ton, if I remember right. It was difficult to
comminute, and did not roast well at all.
The roasted matte from the ore smelting, so-called
first matte, used in part as iron flux, had the follow-
ing approximate composition : Si02 0.8, Fe 42 — 45,
S 2.8—4.2, Cu 3.1—9.2, Pb 13, Ag 67—100 ounces.
When copper percentage rose to 9%, the matte
was roasted again and smelted in a separate blast
furnace with silicious ore, metallic iron, limestone,
and lead dross and scrap for concentrated matte,
which was shipped and sold. Below is a sample of
shipping matte : Cu 37.5%, Pb 12.0%, Ag 157.3,
ounces per 2000-pound ton.
If the siliceous ore was not sufficiently free from
sulphur, an intermediate matte would fall, which had
to be re-roasted and smelted to attain the proper
concentration.
In computing the smelting mixture (furnace charge)
the following slag formula was ordinarily used : Si02
34, FeO 34 = 26.4, Fe CaO 17, RO 15.
This kind of slag was selected on account of its
easy fusibility at a low blast, and because, there was
an abundance of ferruginous ores in hand. Different
conditions prevailing, other types of slag were made ;
for example, when there was a famine of silicious ores
this type was used : Si02 32, FeO 34 = 37.3 Fe,
CaO 12, RO 8.
Under RO are comprised alumina, baryta, zinc
oxide and other bases which have no particular bear-
ing on the character of the slag. Magnesia is fig-
ured as calcium oxide in the ratio of their molecular
weights. With baryta, when present in the ore as
sulphate, that method would not do, for it is not
known what part of it will remain in the shape of
BaS ; it is, therefore, preferable to call the sulphate
of baryta RO, and leave it out of the calculation.
Fluorspar is inert, and the calcium corresponding
to the fluorine must not be drawn into the calcula-
tion. I also consider it wrong to calculate any part
of zinc oxide as lime, as it is carried off by the slag
mechanically and not in chemical combination.
An average of the slag analyses for six months
gives the following result: Si02 34.04, FeO 34.30,
CaO 17.65, Zn 3, RO 10.01, total 99. Lead contents
were 1.1%, silver contents 1.2 ounces per ton. The
bullion contained 218 ounces of silver. The slag
agrees pretty well with the formula used. The slag
from matte smelting did not agree so well with the
prototype, although it was frequently corrected.
The average composition of about 100 analyses was :
Si02 41, FeO 32.8 = 25.5 Fe, CaO 16, RO 10.2, Pb
0.8, total 100.8 ; silver, 1 ounce per ton.
In calculating furnace charges the first considera-
tion is the percentage of lead to be carried, and, sec-
ondly, the required grade of the bullion in silver.
With a high percentage of lead, the extraction of sil-
ver in the bullion will be correspondingly high, and
the fusibility of the charge will be increased, while
with a low one considerable silver will go into the by-'
products, and, incidentally, into the slag, and the
fusibility of the charge will be decreased. There ex-
ists, however, no law in regard to the exact quantity
of lead required for the perfect extraction of a given
quantity of silver from the ore, too many factors in-
terfering with the union of these two metals. Prac-
tice alone can dictate what is proper to do in order
to obtain the best metallurgical and commercial re-
sults. I consider 12$% of lead in the charge a fair
proportion for bullion containing up to 400 ounces of
silver per ton, provided that such disturbing ele-
ments as zinc and barium sulphate are not present in
quantity. At smelter No. 3 the amount of lead in
the charge was arbitrarily set at 11% by the owners
— a figure which was not always justifiable.
In order to show how necessary it is to have high
and low-grade silver ores on hand to choose from, I
have computed a smelting mixture on the above slag
formula from ores Nos. I, IV. VII, IX, and matte,
taking the latter at 42 Fe, 2.8 S, 3.1 Cu, 13 Pb, and
67 ounces silver per ton. Sulphur is allowed for the
copper present to form cuprous sulphide. The bal-
ance is multiplied by the empirical factor 1.3, except
in matte, where sulphur is multiplied by 1.75, to get
the iron necessary to satisfy the sulphur not volatil-
ized. This iron is deducted from the iron in the
charge to obtain the iron available to satisfy the sil-
ica. Since half charges of 500 pounds are weighed
up at the charge scales, the computation is made for
a half charge. The silica, iron and calcium oxide
contained in 200 pounds of slag are drawn into the
calculation, but the weight of the slag is not consid-
ered as part of the charge, according to the prevail-
ing custom. The half charge will then be composed
of 245 pounds bed I, 140 pounds bed VII, 20 pounds
bed IX, 20 pounds bed IV, 35 pounds roasted matte,
40 pounds limestone, total 500 pounds.
This half charge contains 72 pounds of lead (14%),
and should make a bullion containing 600 ounces of
silver, provided no matte were produced.
The amount of sulphur in the half charge is 9
pounds, that of zinc 10.3 pounds, and that of copper
1 pound. There are four basic materials in this mix-
ture to be satisfied with silica. If we leave out the
one containing the most zinc — that is No. IX — the
charge will come out as follows : 200 pounds bed I,
155 pounds bed VII, 75 pounds bed IV, 35 pounds
roasted matte, 35 pounds limestone, total 500 pounds.
In this half charge there are contained 64.6 pounds
lead (13%), and a bullion of 718 ounces of silver should
be produced. The zinc in the half charge amounts
to 9.6 pounds, the sulphur to 8.6 pounds, and the
copper to 1 pound.
Since it is inexpedient to make such high - grade
bullion, it follows that low-grade, siliceous silver
ore should be mixed in to reduce the grade of
the bullion. The amount of slag added to the
half charge to promote fusion is 200 pounds, or 40%.
It is remarkable how much the speed of the fur-
nace is affected by the addition of slag. I have
had occasion to cut it down to 100 pounds and
to smelt even without addition of slag ; but there
was always a falling off in the tonnage of the
furnace, and the resulting slag looked sickly,
which can better be seen than described. The
amount of coke considered necessary for proper re-
duction is 14%, more or less. The half charge re-
quires, therefore, 70 pounds.
The order in which the charge is shovelled into the
furnace is first the fuel, then the charge and last the
slag and any dross or speiss that may have to be dis-
posed of. It is essential that the charge should be
well spread in layers of equal thickness. To deter-
mine whether 140 pounds of coke will fully cover the
area of the furnace, a frame could be made repre-
senting this area and put on the floor. By shovelling
the coke into this frame, and levelling it off, it is
easily seen whether it will cover the whole area or
not. If it should not, both the fuel and the ore
charges must be increased in size. Some smelters
put four charges into the furnace at once; this is
quite practicable at an open- top furnace, but not at a
side feeder. Besides, it is hard work for a Mexican
to shovel without interruption for a longer period of
time and do justice to a proper distribution. Ir-
regular feeding is frequently the cause of derange-
ment of a furnace and shortens its campaign. A
vicious habit of the Mexican feeders was to pick the
limestone from off the charge and throw it into the
furnace by hand. The inexperienced would throw it
all in one place. In sinking it would burn itself caus-
tic, and, on coming in contact with the hot firebrick
lining, it would form a fusible silicate, which, in its
turn, would soon find its way through the red brick
and eat out a big hole above the mantle frame. The
only way to suppress such pernicious practice is to
crush the limestone to pieces of about 2 inches; fines
and dismissals only create hatred against the em-
ployers. One furnace that was well served ran un-
interruptedly for 328 days, while some of the others
which received the same charge, but had bad feeders,
would scarcely average ninety days. The operation
of "barring out " a furnace — that is, to chisel off the
wall accretions (embanques) without blowing out the
furnace, as it is done in Colorado — is impracticable
in Mexico. The temperature of the atmosphere is
hot enough without going into a furnace, and the
workmen have no changes of clothes nor habitations
that would protect them from contracting fatal dis-
eases, like pneumonia. Excessive fuel and high blast
drive the fire up in the furnace, and cause it to blaze
at the top, whereby metals are volatilized, and the
formation of flue dust is increased.
Supposing the composition of the slag be correct,
as proved by the analysis, its assay value indicates
in some measure whether the fuel proportion is too
high or too low. If, for example, the slag assays 1%
lead and 3 ounces silver per ton, the reduction of iron
has been excessive, and the fuel must be cut down.
If, on the other hand, the slag runs 3% lead and 1
ounce in silver, the temperature has been insufficient
to reduce or precipitate all the lead, and the fuel
charge must be increased.

MINING SUMMARY.
ALASKA.
(Special Correspondence). — The t run*-
portation people aro making strenuous
efforts to keep up the boom and nearly all
the DawMin gold is shipped from this
port, which. I understand, Nomo will be
credited with. This city of 15,000 people,
or more, Is kept up by the money of people
who brought the money here from tin-
States anil the little taken out of the
beach sands, and new the latter is cut off
by a decision of Judge Stevens' commis-
sioner.
Tim Lane party has blown in a largo
amount of money, of which the greater
part may bo lost. They will take out
but little money this year, and probably
not much more next. Some of the claims
on Anvil are paying very well, but most
of them aro a blank. No. 2 below Lane's
is closed down and nothing bolow No. 1 is
or will bo worked this summer, if ever. 1
Have prospected the country from Port
Clarence on the west to Golovin bay on
tho east, and found a few rich spots, which
could soon be worked out if they had
water. However, there are thousunds of
little creeks putting into the various riv-
ers that carry gold in more or less quan-
tity, which wiil bo worked more or less
for years to come. But claims that will
pay $10 i>or day to tho hand aro extremoly
scarce, anil they ask a fortune for them.
That is not big when you considor that
you can only work three months in tho
year at most. Tho only redeeming feature
ol this country is tho tundra, which is
usually from 40 to 60 feet deep and always
frozen, and of its value but little is known.
The lead pencil miners have this all
located — hundreds of thousands of acres —
and before they would let any capitalist
have a bond, or what they call a lay, the
capitalist must put up some money, which
tbey are not doing, so far as I can learn.
The country is full of stampeders and as
soon as the cold weather is on they are to
commence, and I am told they get more
or less aid from the transportation and
business men.
Nome, Aug. 3.
(Special Correspondence). — The rainy
season has just set in, giving water in the
gulches and enabling miners to work their
ground. Some claims are being opened.
There is an output from the creek claims,
but not as great as it would be were titles
more sottlod and litigation less rampant.
Some of the best mines on and around
Anvil creek are in the hands of the re-
ceiver, who is working them for the ben-
efit, supposedly, of the litigants, but under
their protests. Of my own knowledge
bench claims have been discovered and
the shafts filled in again, the locators sim-
ply deciding to hold the ground without
working it or letting the value of the find
become known until they can be reason-
ably sure of impartial judgments in the
courts. This feeling of insecurity is gen-
eral and is retarding all development. The
beach miners, who number several thou-
sand, especially feel the severity of this
condition, as arrests aro being made by
wholesale, on complaint of any one who
tan show a recorded location notice,
charging criminal trespass, so that the
highly respectable citizen of the States
finds, on operating his rocker or pumping
plant on the beach of Nome, which he
had thought free to all, that he is a com-
mon felon, and liable to imprisonment for
from one to five years. The net result is
somewhat disheartening, the more so that
the profits of beach mining are, in most
cases, doubtful or negative; and, as the
local paper remarks, many are taking ad-
vantage of the low rates prevailing to
leave. The Nome rush (outward bound)
has begun.
One of the difficulties of beach mining,
besides the legal aspect of from one to five
different locators of tundra claims wishing
to levy "royalty," with the aid of the
criminal court, on an identical strip of
beach (the same was not staked or claimed
by them on the original location), is an
occasional southerly storm, such as we
are having to-day, rooting up the suction
pipes and washing off the sluice boxes or
rockers, washing in the pits and burying
machinery if set too low. I notice one
dredger (a barge in the open sea) has met
disaster, and several tugs, two or three
small sailing vessels and one sidewheel
Yukon river steamer blown ashore and
wrecked. The town is becoming '-'tough."
The few sea dredgers are doing no good.
The one on Snake river is believed to be
making money. Staking off beach claims
was very active on receipt of the news of
the law passed July 6th. It is surmised
that the present workers on the beach
are one and all made to suspend in short
order and perhaps the plants seized for
damages already done the ground of the
intending claimants. This stoppage will
mean an almost total loss to the misguided
who have machinery which they might
stand a show of partly recouping if al-
lowed to continue peaceably for the rest
of the season, since, the expense of erect-
ing plant, laying in supplies and experi-
ence of how to save the gold having been
gained, the larger part Of the ground will
Cay a Profit for running through a sluice
ex. Tho judge's nephew is "receiver"
for most of the Anvil creek claims in liti-
gation. There is probably not less than
$1,000,000 worth of machinery on tho
beach. For myself, the result will be a
net loss. I shall return. 1 have sense
enough not to light the powers that be.
While many of the miners feel like hold-
ing a hanging bee — with the court for
hangee — wherein they would be assisted

Last week was reported a decision of the
Supreme Court ordering the county re-
corder to pay over to the county fees re-
ceived for recording mining claims. An
application is to be made for rehearing in
bank in the case. Recorder Lee says if he
were inclined to accept the late decision as
final, he could not in fairness to those as-
sociated with him give up the. contest un-
til all legal resources had been exhausted.
The recorders of all counties classed as
mining counties are interested with him,
and have been assisting him in carrying on
the litigation. The question is as wide as

terial.
Mr. Best of Los Angeles, who was here
last fall and bonded some claims, writes
that he is confident of getting his com-
pany together and making his first pay-
ment on Sept. 1st.
Both the above parties have some good
prospects among their bonded properties,
and if they go at it wisely they can not
help winning success.
We dislike to see the disposition for one
man to post notices on more claims than
he can do the work. This has been the
ruin of more camps than one, as it holds
back the true prospector from his work.
Meadow Lake, Aug. 20.
From God's Country a 10-stamp mill will

Free Press : The U. S. District Court
has decided a case involving a point of
great interest to mining men, to the effect
that the often - heard contention that
claims may be filed on mineral-bearing
railroad land, whether patented or not,
is invalid. If a patent has been issued to
the railroad company claims cannot be
filed upon the land. The case in which
the decision was rendered was a suit for
ejectment brought by the Mountain Cop-
per Co. against Maginnis, Myers et al.
The mining company purchased several
parcels of patented land adjoining their
Iron Mountain property from the rail-
road. Maginnis and the others located
claims upon the land. The M. C. Co.
brought suit in the Superior Court. The
suit was transferred to the Circuit
Court. It is stated that the defendants
relied largely upon the clause in the pat-
ent issued to the railroad which specifies
land "without minerals." The Circuit
Court in deciding for the plaintiff holds
that the clause referred to is meaningless,
since otherwise no clear title could be con-
veyed by patent to the large acreage of
land whose mineral or non-mineral quali-
ties are open to question.
SISKIYOU COUNTY.
The failure of the Portland G. E. cya-
nide plant appears to have been caused by

Confidence this week and took charge of
the property. Retimbering and enlarg-
ing the main working shaft at the Confi-
dence is progressing ; the mill is being
given an overhauling. At the Grizzly
the main shaft is 820 feet deep. When 20
feet more has been made, which will give
40 feet of sump room, sinking will be dis-
continued, a station put in at the 800 mark
and the vein drifted on. A new hoist will
be placed on the mine and electric power
used, thus permitting the mine to be op-
erated the year around.
At the Harvard mine, Supt. Munger
says lack of water has compelled him to

Independent: Near Sonora the Miller
& Holmes mine is being unwatered.
Operations have been temporarily sus-
pended on the Imogene property. Ow-
ing to the lack of water for power, the
Bonanza Co. have pulled out their pumps;
the mine will fill with water. A new
property is being operated on the Corn-
stock ranch, in the East belt, by the
Golden West M. & M. Co. of San Fran-
cisco. The tunnel is in 850 feet; when 150
feet more is driven, a double compartment
shaft will be sunk. The Gagnere mine,

a borax deposit near Giffin. Locations
cover 2400 acres. All the local stockhold-
ers except Gail Borden have sold out to
the Stauffer Chemical Co. of San Fran-
cisco and Thomas Thorkeldsen & Co. of
Chicago. Christian De Guinge of San
Francisco is president of the company and
Gail Borden secretary. The veins vary in
thickness, being in some places 12 feet
wide. The mining is done by hand. The
ore hauled 60 miles to the railroad is
shipped to San Francisco and Chicago.
The Frazier Company is shipping 150 tons
a month. A railroad from Bakersfield
will reduce the wagon haul to 30 miles,
and then the Frazier Company will put in
a traction road.
A find of boracic ore is reported from
Seymour canyon, 6 miles from Lockwood
valley, from which about fifty tons of ore
a month can be hauled. The new mine is
named the Nighthawk. The average
borate of lime ores, such as colemanite
and pandermite, do not yield more than
from 40% to 50% for best and from 25% to
36% of anhydrous boracic acid for aver-
age ore. The gross value of ore running
40% would be about $88 per ton; from this
would have to be deducted loss in reduc-
tion, charges for mining, hauling, freight,
and cost of reduction. The quotation of
44% ore is about $35 per ton in San Fran-
cisco.

(Special Correspondence). — Leadville
stocks have been active of late, the buy-
ers being mostly local people. As an ex-
ample, the Canterbury, having sixty acres
of patented ground on Fryer hill, with a
150-foot shaft, sinking for the contact, has
issued stock that has sold well.
The Tarshish lease on seven and one-
half acres adjoining the Adams, on Stray
Horse gulch, has a 660-foot shaft, having
opened ore at first contact at 250 feet
depth. Prospecting is being done for the
sulphide contact at the bottom of the
shaft. Stock in the company owning this
lease has been in some demand.
The Valentine lease of 100 acres, in the
southwest part of the district, has three
shafts, the deepest being just over the
contact at 500 feet depth. Stock in this
company is selling at 10@18c per share.
The Home Extension Co., whose hold-
ings comprise mineral rights purchased of
lot owners west of the Home M. Co.
group, are sinking a shaft between Chest-
nut and Second streets. Stock in this
company has sold at 25@40c per share.
Stock in the Home M. Co. is held pretty
close at $8.50@9.00 per share, there being
outstanding a stock issue of 50,000 shares
of the par value of $1 per share.
The Doris, owning ten acres in Iowa
gulch, has been a shipper in the past and
has planned of late for new development.
The Hummer, under bond and lease,
has produced a large amount of lead ore,
has good prospect of getting soon into the

hiU.
The New Monarch, which ships 1500
tons per month of rich sulphide ore, in
which the gold values are prominent, has
a stock issue which sells almost at par.
The California Gulch lease on two and
one-half acres, on both sides of that gulch,
in sinking its shaft 500 feet has got into
the blue lime stratum in which the ore is
expected to be found.

Leadville, Aug. 16.
(Special Correspondence). — The Colo-
rado & Southern Railway is changing its
Leadville trackage from narrow to stand-
ard gauge, which will enable this company
to handle standard gauge cars from
various mines of the district to the Colo-
rado Midland, now a part of the Colorado
& Southern. This enables the road to
ship cars of ore from Leadville to Denver
and Pueblo smelters without sending them
by way of Breckenridge and over Fre-
mont and Boreas passes.
The Penrose shaft, on the Home group,
has encountered a heavy flow of water,
which is being readily handled. As depth
is gained the bottom of the shaft con-
tinues in ore.
Leadville, Aug. 18.
On Little Ellen hill, Leadville gold belt,
the Iszard, alongside the Little Ellen
mine, is being worked by Hobart & Smith.
Miner: General activity in Leadville
district has caused large demand for all
kinds of mining machinery, especially
small hoisting plants and boilers. If the
present demand continues it would be a
paying investment to purchase small 6x8
double hoisters and 25 to 25 H. P. boilers
for rental purposes. A plant of this kind
will cost new about $650 to $800 and will
rent for $25 to $30 a month.
OURAY COUNTY.
(Special Correspondence). — The new
mill of the American Nettie mine started
up last week. It is equipped with plates
and concentrators and has a capacity of
sixty tons per day. The ore is trans-
ported from mine to mill over a wire rope
tramway, 1700 feet long. The Nettie is a
gold property in the main, much of the
ore being free-milling and high grade.
Ouray, Aug. 17.
At Ouray the Camp Bird reports a
strike in the west drifts, in the upper or
old workings, where a crosscut 37 feet
wide in pay ore fails to show the walls.
The sale of the property is not yet con-
summated.
PITKIN COUNTY.
(Special Correspondence). — Smuggler
mill No. 1 is handling about 165 tons per
day, the product being about forty-five
tons of silver-lead concentrates; Smuggler
mill No. 2 handles 100 tons per day, which
is reduced to about 15 tons of concen-
trates.
The Mollie Gibson and A. J. mill,
equipped with seven Huntingtons, twenty-
eight vanners, with crushers and roll9,
averages about 200 tons per day, concen-
trated from six to twelve tons to one ton.
The Mollie Gibson ore is distinctively a
silver-lead ore, while the A. J. ore con-
tains very little of lead. Ores from both
mines carry a considerable quantity of
lime, which is largely eliminated in con-
centrating, as the lime cannot well be
saved without gathering with it too much
of the silica.
In various mines of Aspen the lime
product is an important factor in settle-
ments with the smelters.
The Aspen mine ships about 100 tons
per day. The district, as a whole, ships
out about 5000 tons of crude ore and 3000
tons of concentrates per month. The con-
centrates run high in lead, probably from
30% to 60%.
The Colorado Midland is extending a
branch 1£ miles up Castle creek to get ac-
cess to the Newman tunnel of the Percy
Con. and other properties on the Castle
creek side of Aspen mountain.
A new pumping station is being put in
at 1060 feet depth in the Mollie Gibson.
Pumps from the old A. J. workings will
be installed there. The workings of the
two properties are connected underground
by a well-equipped trolley line.

TELLER COUNTY.
(Special Correspondence). — Parties in
control of the Colorado-Philadelphia Re-
duction Co. at Colorado City and of the
National Gold Extraction Co. of Florence
have plans made for the erection of a
crushing and sampling plant near Victor,
which will have four sets of 16x36-inch
rolls and two 15x24-inch crushers, and to
have a capacity of over 1000 tons per day.
This sampler will be an adjunct of the re-
duction plants of the companies named.
The reduction plant of the Colorado-Phil-
adelphia Co. at Colorado City employs
chlorination as a means of extraction, and
has run steadily, handling about 350 tons
per day. This is doubtless the only one of
the large mills in the valley which has re-
cently run steadily at full capacity. This
company is completing a second reduction
plant of same character at Colorado City,
which will be in operation before the close
of the year, making the combined capac-
ity of the three plants of this concern
nearly 1000 tons per day. It is claimed
this milling concern has the contract to
handle the output of Stratton's Inde-
pence mine — whose shipments now amount
to 200 tons per day — for five years. It is
also pretty well understood that the
Portland G. M. Co. will erect a reduction
plant at Colorado City to handle the ores
from the Portland mine, which now ships
150 to 200 tons per day.
The growing importance of Colorado
City as a milling point is the outgrowth of
the construction of the Colorado Springs
& Cripple Creek Railroad, in which enter-
prise many of the more extensive mine
owners are interested as shareholders.
This road .is almost completed and will be
in operation by the close of the year. It
has very extensive trackage throughout
the district, where it will be electrically
operated; but it will be operated as a
steam road from Cameron, at the foot of
Bull, to Colorado Springs and Colorado
City.
On milling rates for district ores there
appears to have been considerable reduc-
tion, though it has been a matter of pri-
vate arrangement rather than a general
announcement. The railroad rates favor
the mills rather than the smelters.
Ores running $15 to $30 per ton pay a
$3 rate to the smelters; ores running same
grade pay $1.50 to $1.75 per ton shipped to
the mills in the valley.
The Economic Extraction Co., which
handles the ores from those mines con-
trolled by the Woods Investment Co., is
milling from 100 to 150 tons per day at
present.
Within a month the Strong mill will be
shipping again, having been closed down
several weeks putting in a plant of ma-
chinery.
Within the past few months a large
area of land has been patented ur-der min-

that have already been extracted, out of j
which there has been paid $2,000,000 in
dividends since tho English company took
charge. They state that they deliberated
a long time concerning the introduction of I
a chlorination works, but that such ad- |
vantageous rates were made with one of

ject.

C. R. Hosmer, director Center Star and
War Eagle mines, says a deal is on with

was to handle and smelt ore for the mines
at a figure which is understood to be
$2,000,000 annually. He says that ship-
ments from both mines are being held,
pending the signing of the agreement, by
which the War Eagle would receive spe-
cial terms for transportation and smelt-
ing. This, he says, would so reduce the
cost of mining that it would be possible to
profitably mine lower grade ore than had
been done hitherto. Under this agree-
ment, it was further added, the War
Eagle and Center Star would ship a mini-
mum of 1000 tons per day.
A New York paper says the Cariooo

"Officials are not pleased with the size of

$135,275, which was sent to the assay of-
fice recently, by the New York branch of
the Bank of Montreal, to be smelted. The
hydraulic miners of British Columbia
made the lump so large that Supt. Mason
of the assay office will have to order a
special smelting pot, in order to have a re-
ceptacle large enough to hold this 'king'
lump, while it is melted to he run into
bars. The weight of the lump— 7897
ounces — made the service of four men
necessary to place the cone upon the
scales."
The Canadian Pacific's smelter at Trail

to the plant stated include the following :
Six straight-line roasting furnaces, with a
maximum capacity on easily roasted ore of
150 tons daily ; two lead furnaces, with
daily maximum capacity of 250 tons each ;
one copper furnace, inside measurement
44x160 inches, capacity 300 tons per day ;
crushing plant to handle 1500 tons per

THE KLONDIKE.
From Dawson Wilson Foster writes the
Victoria Times under date of July 30th
regarding the new quartz strike in Indian
River district: "I saw the samples and an
assay certificate showing $2 per ton from
one sample and $5 from another. It is
now sixty days since the strike was made,
and there is no shaft being sunk, not $100
worth of work done, even to serve as as-
sessment work. It would be criminal to
allow exaggerated reports of untold wealth
in quartz finds to go abroad uncontra-
dicted and cause another wild stampede of
"Cheechakos " or "tenderfeet " into the
Klondike. We have as many people here
now as we need until more work has been
done to develop this country. This is not
a poor man's country. In fact the poor
man has no country ! As soon as a poor
man strikes it rich he either goes insane,
drinks himself and dissipates himself into
an untimely grave, or becomes just as ar-
rogant, greedy and insulting as his
wealthy brothers in other camps, and
tries to swallow up the whole creek, pay-
streak, gravel and all. This is not a per-
sonal remark, and there are few excep-
tions to this rule. There are at least 1000
prospectors for quartz in the Klondike.
The Alaska Exploration Co. has already
spent $100,000 cash in quartz prospecting. "
The statement that the Dominion Gov-
ernment had abolished the 10% royalty in

tax establishing a compulsory assay office
in Dawson, is officially denied by the Min-
ister of the Interior.

He had been directing men fighting- forest
fires. Mr. Ferris was thrown to the
ground with great force and his skull
crushed. Recently Eastern men secured
an option on his mine for $2,000,000, and
on the day of his death he received word
that a representative of the purchasers
was en route to the mine to close the
deal.

Catalogues Received.
Apart from the practical character of
the catalogue on mining machinery re-
cently sent out by the Edw. P. Allis Co.
of Milwaukee, Wis., the style of its publi-
cation is good illustration of the advance
in that kind of mechanical treatise. The
engravings are of the same high-class
grade one expects to see in the best maga-
zines. Evidently the Allis people believe
that if a thing is worth doing at all it is
worth doing well, and a concern that goes
to such expense in a trade treatise may
justly claim favorable notice for what it
makes for miners.

Notices of Recent Patents.
Among the patents rocently obtained
through Dewey, Strong & Co. 's SCIEN-
TIFIC Press U. S. and Foreign Patent
Agency, the following- are worthy of spe-
cial mention:
Apparatus for Cutting Metal
Shavings.— No. 655,868. Aug. 14, 1900.
August Holtgen, San Francisco, Cal. One-
half assigned to W. E. Hampton, same
place. This invention is designed to cut
sheets of metal into thin shavings. It
consists of a journaled arbor with means
for applying power to revolve it, means for
securing one edge of the sheet of metal to
the arbor so that the sheet may be coiled
thereon to any desired thickness, a cut-
ting tool, and means for advancing it
parallel with the arbor so as to cut shav-
ings from the end of the roll of metal.
The tool-holder comprises two parts, one
of which is slidable in guides parallel with
the arbor and the material to be cut, and
the other is screw-threaded, hinged and
closable upon the first portion and also
upon the feed screw which passes through
the tool-holder. The end of the feed
screw carries a ratchet wheel and a pawl
is eccentrically mounted upon the arbor
so as to turn the ratchet wheel at each re-
ciprocation and thus rotate the feed
screw and advance the tool-holder by
small progressions so as to make a con-
tinuous cut of the metal coiled upon the
arbor.
Self Lighting Cigars. — No. 655,864.
Aug. 14, 1900. B. Heimann, San Francisco,
Cal. One-half assigned to I. Dannenbaum,
same place. This invention relates to a
cigar carrying upon itself a means for its
ignition without the use of matches. It
consists of a specially prepared compound
of ignitable material mixed into a paste
and incorporated with the ends of the
rolled leaves of the cigar so as to form an
essentia] part of the structure. The cigar
being rolled, this saturated end can at any
time be ignited by rubbing it upon a sur-
face prepared for the purpose, and which
will through its chemical action upon the
compound on the cigar cause the latter to
ignite. It is very convenient for windy or
difficult situations.
Vineyard Harrow. — No. 655,859.
Aug. 14, 1900. J. F. Fay, Geyserville Cal.
Assignor one-half to W. S. Vaughan, same
place. The object of this invention is to
provide a harrow which is especially de-
signed to be used in vineyards. For such
purposes it is necessary that the side
frames of the harrow carrying the teeth
should be adjustable to stand at different
angles with relation to the central sup-
port, and the ground over which they
travel. For this purpose the harrow is
constructed with a central longitudinal
beam with draft attachments and two or
more parallel toothed beams are located
upon each side of the draft beam, and
diverge from front to rear with relation
to this beam. They are rigidly secured
by angle plates at the front and transverse
uniting plates at the rear. Loose link
connections between the front and rear
ends of these toothed beams and the draft
bar allow them to tilt to suit the surface
of the ground, and a lever fulcrumed at
the rear of the draft bar is connected
through transverse levers so as to raise
and lower the tooth beams to stand at any
angle with the draft beams. They can
then be locked in any position of adjust-
ment.

Visible supply of copper in England
on Aug. 15th was 32,460 tons — an increase
of 3547 tons in the first half of the month.
Supplies for the half month were 12,915
tons and deliveries 9368 tons. February
1st was the low point in supply this year,
with 21,327 tons; it has increased steadily
since to 32,460 tons Aug. 15th, or 11,133
tons in all since Feb. 1st — 50%. The in-
fluence of the heavy American exports of
copper evidently are telling on the build-
ing up of supplies. The supply Feb. 1st
was down nearly to one month's consump-
tion. Since then Europe has absorbed an
immense amount of American copper.
For the first seven months of 1900 no less
than 101,903 tons have been exported
from the United States — nearly two-thirds
of the entire American production of
157,592 tons, against much less than one-
third in the same period last year.
LEAD.— New York, $4.25: Salt Lake
City, $4.00; St. Louis, $4.20; San Fran-
cisco $5.00, carload lots; 5}c 1000 to 4000
lbs.; pipe 6|, sheet 7 J, bar 6c. London,
soft Spanish, £17 15s.
The Treasury Department reports that
for the fiscal year ending June 30, 1900,
the imports and exports of lead were as
follows:
Pounds.
Imports 196,378,961
Exports 166,254,778
Foreign lead remaining in U. S. 30,124,183
Lead in warehouses June 30, 1899 17,399,593
Lead in warehouses June 30, 1900 33,836,374
Increase in warehouses during
last fiscal year 16,436,781
United States consumption of
imported lead last year. . . . 13,687,402
In line with the A. S. & R. Co. the Gug-
genheims guarantee their sellers $4 per
100 pounds for all the lead they may pro-
duce for the remainder of 1900 — the $4
rate to apply to all settlements that have
been made since Aug. 1st, on which day
the agreement with the A. S. & R. Co.
went into effect.
Replying to a question asked by the
Salt Lake Tribune as to the application of
the agreement by which the lead produc-
ers of Utah are to receive $4 per hundred
during the balance of the year for their
product, Manager Jones of the A. S. &
R. Co. said it was open to all who appear
in the Salt Lake market, whether they
come from Idaho, Nevada, Wyoming,
New Mexico or Colorado, or from the
Dominion of Canada on the north. What
agreement, if any, is governing the mar-
ket at other smelter points, Manager
Jones did not know, as he was not sup-
posed to be concerned in the affairs of
those outside of his own jurisdiction,
which is confined to the Salt Lake plants.
Messrs. Guggenheim will pay $4 per
hundred pounds in every market entered
by them, whether it be in Idaho or Mon-
tana, Nevada or Wyoming, Colorado or
New Mexico.
J. H. Weddle, manager of the Arkansas
Valley plant of the A. S. & R. Co., ex-
plains how the $4 per hundred rate was
brought about : "For some time past the
production of lead in this country has
been very heavy. This naturally tended
to send the price down considerably below
$4, and the only way that the market
could be sustained was to export the
metal. This, of course, had to be done at
a loss, in order to compete with the for-
eign market. Some time ago, at the in-
stance of the big lead producers of the
Cceur d'Alene country, a conference was
held with the officials of the A. S. & B.
Co., and a plan agreed upon for making a
stable price. The lead miners generally
throughout the West have accepted the

structural material manufacturers at
Pittsburg this week ordered a cut of $8
per ton In all shapes and sizes, effective at
once. It is another uiovo growing out of
the Gates maneuver on steel and wire.
It was learned that some of the big com-
binations had broken into tho structural
material trade. Tho minimum of the
structural schedule was $1.90 for 15-inch
beams and under, but the material that
was competing with tbo pool was selling
for $1.30 for similar sizes. Should the
others meet the cut of the pool, there is
no tolling where the end will be, as the
associated manufacturers are determined
to maintain control of the product.

CROWN GOLD MILLING CO.
Manufacturers of the "CROWN" CONCENTRATOR and CROWN
ORE SIZER. A dry process of sizing and concentrating ore, sand or
gravel. Designed to accord fully with the laws of specific gravity,
and especially adapted to refractory ore or localities where there is
no water.
The chief claims for the Crown Concentrator are that it occupies
less floor space and has nearly four times the capacity of any wet
concentrator; that it will concentrate ores containing base and refrac-
tory metals that ordinarily slime and carry off values; that it effects
a saving of values far above the ordinary methods of concentration.
We have, now in operation, a complete plant
for crushing, sizing and concentrating ores by the
Crown Dry Milling Process.
Mine owners desiring tests made can forward
us, freight prepaid, not less than 1000 lbs. nor
more than 4000 lbs. of sample, for which a
charge of $20 will be made. (This amount in-
cludes assaying, etc.)
Ores for which this process is adapted and of
which consignments are solicited are any con-
centratable ores, pulps, tailings, or sands, carry-
ing sufficient values, whether they have hereto-
fore been profitably concentrated or not.

THE GRI
THREE ROLLER
ORE MILL.
The Griftiu Three Roller Ore Mill is a Bimp.y constructed Mill, Buitable for working all kinds of ores that
require uniformly fine crushing by the wet process. This Mill is a modification of the well-known Chilian
Mill, but tho rollers run upon a crushing ring or die, which i* im/lincd inwardly at an angle of about 30 degreos,
the rollers themselves also being inclined to the central shaft of the Mill, thus utilizing tho centrifugal force,
us will as tho weight of the rollers themselves as a crushing agent. The Griffin Three Roller Ore Mill [s there-
fore a -Mill of great strength, and has few wearing parts. Wo construct these Mills with extreme care, using
only the bost of raw materials, which are most carefully worked by men who are specialists as mill builders.
Wfl sell the Griffin Ore Mill on its determined merits, and will gladly supply full information X'ogarding it to
any one.

THE IMPROVED BARTLETT CONCENTRATING TABLE.
The BARTLETT CONCENTRATING TABLE has boon GREATLY IMPROVED recently by the substitution of iron
in place of wood wherever possible. It is now built with SOLID IRON TOP, PLANED TO A TRUE SURFACE AND
POLISHED ; all parts are made by template and EACH PART BEING INTERCHANGEABLE. As now constructed,
the table has no special wearing parts and will last for many years. It has a CAPACITY OP FROM FIFTEEN TO
FORTY-FIVE TONS IN TWENTY-FOUR HOURS, according to the class of ore worked. It is the only table in the
world which will take the place of jigs and do away with all costly and complicated machinery.
It is Especially Designed for Separating Zinc from Lead.

All of our latest Improvements are
embodied in this instrument and it is
the result of our 18 years' experience in
building balances.
Among the noteworthy features In
the make-up of thlB balance is the
improved adjusting device, herewith
Bhown.
No. 1 Special Button Balance with 5-inch beam. Sensibility
1-200 Milligramme. Made for particularly accurate and rapid
work and is guaranteed to be the finest balance on the market.
It is the balance used by Prof. Forsythe of the Lawrence Scien-
tific School. Harvard University, for scientific research. Send
for Catalogue A, illustrating and describing a full line of aBsay
and analytical balances, to
\A/m. Alnsworth
(Successors to WM. AINSWORTH.) DEIN
The adjusting device will appeal to
the assayer as the simplest and most
convenient means of checking the
I beam, and consists of a Btar wheel on a
threaded arbor, mounted on the center
edge back of the beam.
■ By turning this wheel backward or
forward, it Ib moved along the arbor
and bo adjusts the beam to equilib-
rium.

FOUR and SIX=FOOT FRUE VANNERS
With Brownell "Patent Lip" Flange Belts.
1 — " — STANDARD MACHINE OF THE WORLD.
When a Concentrator like the Frue Vanner lias been on the market nearly two decades, and the sales have constantly
increased, it is safe to say It is the "Standard Machine of the World." More Frue Vanners have been sold during the last
twelve months than for the same period at any time during the history of the machine. Practical mining men in all parts of
the world where mining is carried on will testify as to its merits. It is the " standard11 which all competitors are trying to
imitate.
The results obtained by this machine are the " acme11 of concentration, and several cheap and untried machines that
have lately come on the market compare by it. The manufacturers will tell you that they are "just as good, and
cheaper," etc. The facts are that no other concentrator made has an equal capacity, or will yield as clean a concentrate
with as small loss in the tailings as the Frue Vanner. The amount saved from the lower first cost of an inferior machine
counts little in the year's results, when compared with the increased output from a Frue. This machine not only gives bet-
ter results at both ends of the belt (i. e., clean product and poor tailings), but is operated at less expense and requires leRS
attention than any other machine on the market. At the Alaska-Tread well mine, where they have ordered over 350 Frue
Vanners, oae man attends 48 machines for 12-hour shift.

At the Paris Exposition the United States wins
pre-eminent recognition in mining and metallurgy.
There seems to be a hopeless difference of opinion
between the Boston & Montana M. Co. and its re-
ceiver, Thos. Hinds. The latter asks for $400,000
for his services and $14,000 for an assistant. The
company proffers Mr. H. $50 for a receipt in full, and
is willing to pay the assistant $20. Incidentally the
company also asks the attorney appointed by the re-
ceiver to take $200 for his bill for $15,000 and call it
square. The value of the services of a mining en-
gineer is also a subject of question, the company
scaling the fee asked by Mr. Brown from $1000 to
$25, and curtly claiming that the latter sum repre-
sents the full value of such services.
In an account of the burning of the Weldon mine
plant at Leadville, Colo., this week, is the usual
statement that the engineer stuck to his post until
all the men were hoisted from below : then he got out
so badly burned that he is not expected to live. In
battle, in the fullness of his pride and strength, the
soldier bravely faces death, upheld by the contagious
courage of his comrades. He is deified as a hero in
song and story, and deservedly. No less heroic,
rather more, is the brave man who, alone, amid fall-
ing timbers and roaring flames, stands at his station
and saves the lives of his fellow workers in the mine
who depend upon him for succor. All honor to the
engineer of the Weldon mine and such dauntless souls
as his, who deserve recognition for heroic devotion to
duty!
The mutual relation of a profitably producing mine
and a profitably operated smelter is aptly illustrated
by going into some figures produced by the News Bu-
reau concerning the operations of the Centennial-
Eureka mine, Tintic district, Utah, for the first six
months of the year. During that time the mine pro-
duced $722,655. There were mined and shipped
20,000 tons ore, which yielded 1,148,455 pounds cop-
per (2.87% to the ton) ; 14,628.081 ounces gold (0.731
ounce per ton); 384,638.27 ounces silver (19.23 ounces
per ton). The smelter to which the ore was shipped
deducted 1.3% of the copper contents, and made fur-
ther deduction in calculating the price paid, mak-
ing it net about 13 cents per pound. For the gold
the smelter paid $19 per ounce ; for the silver, 95% of
the assay value. This, with the regular smelting
charge — a total of about $13 per ton — would bring
the smelting charges to about 40% of the value of
the ore.
Profit in Mining Investment.
There is a present inequality of conditions that
could be mutually improved. Money is so plenty, and
rates of interest consequently so low, in the East
that the United States is lending money to England,
the late British loan being largely taken in New
York. Call money is 1}%, and 3% securities are at
a premium. In this west half of the same country
are opportunities for profitable investment of this
surplus idle wealth. The mineral industry of this
region could be exploited to the common profit of all,
the country built up and the millions begging for in-
vestment made to yield satisfactory returns. With
better understanding of the facts this could be
brought about. With idle millions seeking 2% invest-
ments and idle mines capable of producing 20%
profit, the times seem propitious for " getting to-
gether." One obstacle to such mutual gain is the ill
will and distrust that arise from ignorance of the
facts. There is considerable ancient prejudice still
existing east of the hundredth meridian regarding
mining, which is still considered a game of chance in-
stead of one of skill. Eastern people do not realize
that in no other branch of industry has there been
such advance as in the mining industry in the last
ten years. Improved and economical mining and
metallurgical mothods have made possible profit
where formerly existing facts precluded successful
working. It is to be said that in many cases sad
experience has deterred further investment. But
were that to count, nobody would do anything in any
line of business. Lack of knowledge and absence of
ordinary business judgment are fatal to success in
any commercial pursuit, and mining is now made just
as legitimate a form of business as anything else.
Rightly managed, with due attention to business
requirements, any business should prove reasonably
profitable, the advantage in the mining business
being that the customer seeks the producer ; the de-
mand is constantly commensurate with the supply;
the destructive competition existing in other lines is
notably absent, and many of the vexatious problems
attendant upon other forms of commercial activity
do not arise. There is plenty of capital awaiting
profitable investment in the East for honest, legiti-
mate mining, but none for boom deals or wildcat
schemes. How to induce the profitable investment
of that capital is a subject on which much has been
said, some of it unwisely. The business of enlisting
such capital is legitimate, honorable and necessary,
and should be so conducted to secure success. There
should be truthful statement, time given for investi-
gation, prices made commensurate with value, and
constant recognition of the fact that in these things
honesty is not only the best but the only policy. Of
course, there are always timid and distrustful souls
who fear to pay $19 for a $20 gold piece, but, apart
from these, there are plenty Eastern people who
want profitable investment for their surplus money,
and who have nerve and intelligence enough to buy
what will yield such return if its worth can be satis-
factorily shown to them.
When such statements as the above appear edi-
torially in the Mining and Scientific Press, the usual
result is a host of replies from Eastern readers,
which, summed up, are about like this : " If in your
' west half of America ' exist such valuable mining
property as you say, why don't some of your wealthy
residents take such good things themselves ? Why
should Eastern or foreign capital be sought ? " im-
plying that Western residents take the. good things
and want to unload the refuse on the unknowing alien.
The answer in short meter is that the area and ex-
tent of such possible investment with profit exceed
the financial ability of any limited class. Thousands
of men resident in "the west half of America"
have grown rich in mining, and invested their sur-
plus in other mining projects ; but were their num-
ber increased a thousand fold, and their investments
correspondingly augmented, the area of probable
profit-producing mining investments would not be
materially curtailed in scope or extent.
The increasing importance of the oil industry of
California makes prominent the question of transpor-
tation. The one plan that at once suggests itself
is the piping system, which has been carried to
proficiency in the Eastern oil fields. In a limited
way piping of oil has been done in California, but the
fact that the conditions in California are different
from the Eastern States does not warrant the idea
that a great system of distribution and transporta-
tion of oil can be as readily produced here as in the
Central States. There are different oil gravities in
different districts, and in some instances the oil is of
so low a gravity as to preclude successful prosecu-
tion of the plan. The question of getting the oil from
the well to the consumer is of immediate commercial
importance. Probably one of the first steps will be
the adoption of a system of grading the oils and the
gradual extension of .the present pipe lines.
The London Mining Journal of the 4th ult. has a
page communication, a diatribe directed against
American mining engineers, anonymous, and betray-
ing a bitterness that precludes discussion of the
facts. According to the anonymous correspondent
of the London Mining Journal, American mining en-
gineers are everything that they should not be, which
is not a flattering comment on the business judgment
of the British mine owners who have been all along
eager to secure the services of American mining en-
gineers in positions where skill, experience, ability
and all the other elements that go to make up a suc-
cessful mining engineer are required. The fact that
the directors of many of the most reputable British
mining companies made wise selection of American
managers with great financial success, militates
against notice of the charges of the anonymous Brit-
ish critic, whose hostility may come from the envy
sometimes engendered in the breast of the unsuc-
cessful. There are two kinds of people in the world-
men who do things, and men who tell how things
should or should not be done. The American mining
engineer well represents the former class ; the Lon-
don critic as fittingly represents the other. Nothing j
is so cheap as a sneer, and sneering critics are usu- I
ally found among the ranks of the unsuccessful. The
American mining engineer needs no champion ; he
began to labor in the South African gold fields ten
years ago, and out of the chaos of 1890 raised the
industry to the prosperity it enjoyed just before the
present war. The attack noticed is not the first of :
the kind, and those things need not be taken seri- :
ously. The American mining engineer made the ,
Rand what it is ; dominates the Rand to-day, and
now having shown how the work should be done (it i
having become a manufacturing and mechanical
proposition), probably less valuable men can continue
on the lines indicated, for a time at least. Any
answer to the attack referred to can best be left to
those best competent to judge — namely, the directors
and owners of the mines — the criterion being success.
This last year of the century is a great one for the
prospector. He is out everywhere prospecting for
gold and copper. Thousands of him have gone be-
yond the Arctic circle, past bleak Cape Nome, across
to Siberia, through the hermit kingdom of Korea,
along both shores of Bering sea and across British
Columbia. Others have scattered with profit over a
more attractive area in this west half of America
that was ridden over years ago by horseback pros-
pectors who announced that there was ' ' nothing in
it." More accurate attention to detail proves to
their successors that there is a good deal in it. Like
all connected with the mining industry prospectors
are learning, a good deal of the old self-sufficiency
has gone, and they are not above taking points from
the experience and knowledge of others. The pros-
pector of 1900 knows better than any of his prede-
cessors the nature of gold, its peculiarities, where to
look for it and how to get it when found. He no
longer devotes all his time to quartz, but tests other
formations known to be gold bearing. The pros-
pector is the avant courier of the miner ; he is as
"the voice of one crying in the wilderness make
straight the way of the Lord"; he rarely makes a
good miner, and a good underground miner as rarely
makes a good prospector ; his mission and function
is to scout ahead of the regular army, discover and
explore, indicate where lies the treasure and leave
to others the work of exploitation and development.
With him lingers what is left of the picturesque in
mining.

The 50th anniversary of the discovery of gold in Cali-
fornia was celebrated in San Francisco, in January, 1898,
with great splendor. The celebration on the 9th, 10th

versary of the admission of California into the Union.
It is altogether practical to build a good-sized dam,
oven to the height of 100 feet, of material transported

Probaly the highest in altitude of any smelter in the
world is the smelting plant of the Backus & Johnson Co.,
Casapalca, Peru, on the Oroya Railway, in the Andes
mountains, 13,606 feet above the sea, and about 100 miles
inland. Nearly 500 men are employed, and the annual
profit is said to be about $100,000.
The trend of training for mining engineers is to make
mining more mechanical and ore treatment more chemi-
cal, introducing order and system and occasioning more
economical working methods. There is also a tendency
toward a general interchange of opinion and a realization
of the futility of attempts at secrecy in metallurgical pro-
cesses.
A TOOL sharpener says for picks he has a box that
holds about 200 pounds dry sand, which is always kept
dry. After dressing the pick he allows it to cool about
an inch, then sticks it down in the sand and leaves it
there until it is nearly cold, and the sand will do its work.
He asserts that picks thus treated are tough and will
give satisfaction.
Part of the duty of the manager of a considerable
mining property is to see that a complete and accurate
system of mine cost accounts is kept, and nothing in its
way is more conducive to economy and profit. Such cost
sheets secure and make necessary close attention to de-
tail and show where the little leaks are that in the aggre-
gate so often drain off possible profit.
A prominent mining engineer, in sending a commu-
nication of practical value, says: "This is a matter of
reciprocity. I have received so much real information
tersely given in 'Concentrates' that I feel impelled to
make some return." A good many whose opinions are
worthy of notice are pleased to say that they feel in-
debted to this page for much of value in their work.
About as near to a feasible plan of "co-operation " in
actual mining work as most people usually get is where
mine leasers pay a royalty on ores produced. There are
other methods, feasible and commendatory, as where a
prospector is grubstaked, or where promising property is
developed, or where practical miners make a good mine
by common effort (as in the case of the W. Y. O. D.,
Nevada Co., Cal.).
Some up-to-date users of machinery now consider that
the best way to use a tool is to work it for all it is worth ;
put as few repairs on it as possible, and drive it to death,
the increased product justifying the rapid depreciation.
They figure, too, that a tool or machine likely to become
obsolete is not to be cared for or kept too long, but to be
discarded for improved makes as soon as necessary, and
that it is "cheaper " to throw out a machine and get a
better one if the latter can produce more work, this as a
matter of shop economy.
Molybdenum in its chief ore, molybdenite, resem-
bles in appearance "black lead " or graphite. The min-
eral contains 59% molybdenum and 41% sulphur; it is
brittle, difficult to fuse, specific gravity 8.62, and is con-
verted into molybdic acid by boiling with nitric acid;
it is used in the determination of phosphoric acid, in the
preparation of blue carmine for coloring porcelain, and
as a substitute for tungsten in making hard, brittle
steel. The market for it is very limited and uncertain
and can be easily oversupplied.
In preparing drills from hammered steel much de-
pends upon the heating for temper. The drill should be
sharpened to as acute an angle as will stand up to the
rock to be worked. To avoid breakage, heat slowly to
cherry red, getting an even heat on cut of bit, then with
clean, soft water dip slowly, taking out drill in time to
leave sufficient internal heat to start the temper and
toughen the bit, leaving it a light straw color. There
is a difference between a brittle-hard and a tough-hard.
If you chill in water without starting the temper you get
a brittle-hard.
If a vein enters a side line and departs out of the same
side line, the miner has no extralateral right whatever,
but is confined solely to his intralimital right of mining
within his lines entirely. If a miner locates along the
course of his ledge 1500 feet, he can have only one dip
right; he may discover a ledge that runs across his loca-
tion, but ho can not follow it on its dip beyond his end
lines. But if ho mistakes the course of his vein in mak-
ing his location, his ond lines will become his sido linos,
and then ho will have the right to follow the ledge on its
dip beyond his new side lines, which were origiiiall.v his
end lines.
Simple fire extinguishers can be made for use around
a mill or mining plant : twenty pounds common sail
pounds sal ammoniac (nitrate of ammonia i, are to bo dis-
solved in seven gallons water. Put thesolution into thin
glass quart bottles, cork tightly and seal to prevent
evaporation; set around whore they will be handy, yet
not in the way. In case of fire, throw so as to break in
or near the flame. If the lire be in cotton or other soft
stuff that will not admit of the bottle breaking, knock off
the neck and scattor the contents. The breaking of the
bottle will liberate a certain amount of gas, and the heat
of the fire will genorate more that will choke and stifle
the flame.
Concerning the "purple of Cassius" tost for gold,
previously mentioned, an expert in metallurgy writes:
"With regard to tho chloride of tin test for gold, it is
utterly unreliable and uncertain in the presence of cya-
nide of potassium. The solution must first be evaporated
to dryness with a little aqua regia to destroy tho cyanido
before the test is applied, and then on diluting the resi-
due with a little water the test may be applied. But it is
much better to evaporate a 100 cc. in a lead tray and
cupel the residue and determine the gold quantitatively,
or else evaporate 10 A. T. with litharge and run it
through the crucible assay and cupel the button. It is
very much more satisfactory and not much more
trouble."
Osmium is the heaviest and most infusible of the
metals. Osmiridium is a natural alloy of osmium and
iridium. This metal, or alloy, has been found in various
placer mines in California, particularly in the northern
part. Owing to its high specific gravity, in washing sand
and gravel it concentrates with the gold. It can be eas-
ily distinguished by its bright metallic color and flat,
scaly appearance, is insoluble in acid, and can not be
melted by ordinary furnace heat. The shape of grain is
irregular, has a ragged edge, and varies in size from that
of fine to coarse sand, and often larger. As the market
for osmiridium has been limited, little attention has been
paid to it on this coast, but it is believed considerable
quantities may be found if miners will turn their atten-
tion in that direction. Should anyone find any of this
metal, the Selby Smelting & Lead Works, 416 Montgom-
ery St., San Francisco, will be pleased to quote rates on
receipt of sample.
The appearance of a halftone engraving in the issue of
Aug. 18, from a photograph taken by moonlight, has
elicited several letters, some saying they did not believe
that a photograph could be taken by moonlight, others
citing similar instances of successful moonlight photog-
raphy, and others asserting that there exists a process
of photography without light, though there is no justi-
fication for the use of such a contradiction in terms,
as any one successful in securing pictures "in the
dark " has simply succeeded in demonstrating that light
exists in places and substance where it has not hitherto
been recognized. If uranium is placed on a photographic
plate in what appears to be perfect darkness, and al-
lowed to remain for some days, the plate is acted upon as
in ordinary photography. Mercury, magnesium, nickel,
pewter and ten other metals give off rays capable of
reproducing an image on the substance on a photo-
graphic plate without the assistance of a light in the
ordinary sense of the word. A polished piece of zinc, if
laid on a highly sensitive plate in a dark cupboard, will,
even in four or five hours, produce a complete picture of
the zinc, showing the scratches or any ruled lines or pat-
tern drawn on it.
In the case of the Marburg lode mining claim at
Pueblo, Colo., the Secretary of the Interior has this
week made a decision of importance to miners every-
where. He says : "When the right to a patent to a.
mining claim has been fully acquired the equitable title
in the purchaser is complete and there is no obligation on
his part to make further expenditure iu labor or im-
provements on the claims under Section 2324, Revised
Statutes, and no interests can therefore be acquired by
relocation or otherwise against him. The annual ex-
penditure of $100 in labor or improvements on a mining
claim, required by Section 2324, Revised Statutes, is
solely a matter between rival or adverse claimants to the
same mineral land and only goes to the right of posses-
sion, the determination of which is committed exclusively
to the courts. It is a matter with which the Land De-
partment has nothing to do and hence can make no
determination with respect to it; and the failure of
an applicant for patent to a mining claim to prosecute
his application to completion by filing the necessary
proofs and making payment for the land within a reason-
able time after the expiration of the period of publication
of notice of the application, or after the termination of
adverse proceedings in the courts, constitutes a waiver
by the applicant of all rights obtained by the earlier pro-
ceedings upon the application. Where an adverse claim
is filed during the period of publication it shall be upon
oath of the person making the same, and shall show the
nature, boundaries and extent of such adverse claim and
all proceedings except the publication of notice, and mak-
ing and filing the affidavit thereof shall be stayed until
the controversy shall have been settled or decided by a
court of competent jurisdiction or the adverse claim
waived."

Charcoal Precipitation from Cyanide
Solutions.
To the Editor : — Has anything of technical value
recently heen published concerning the use of charcoal in
gold precipitation from cyanide solution '? You used to
publish a good deal on this subject.
Los Angeles, Cal., Aug. 25.
Several questions similar in character to the above
have been lately received. Much on the subject has
appeared herein. Probably the latest most extended
discussion of the subject is contained in a paper read
by Jno. I. Lowles before the Institute of Mining and
Metallurgy. In that monograph "On Charcoal Pre-
cipitation from Auro-Cyanide Solutions," Mr. Lowles
says on the subject of the precipitation of gold from
cyanide solutions by means of charcoal, that outside of
Victoria it is but seldom employed, but there it is
used to the almost total exclusion of any other
method. The number of cyanide plants, small and
large, throughout the colony is very great, owing to
the numerous heaps of tailings on living mines and on
abandoned properties, accumulated during the forty
odd years of the existence of the quartz mining in-
dustry in Victoria. In the greater number of these
installations the charcoal method is employed, in
many cases probably in imitation, rather than with
any definite grounds for its superiority over the zinc
process.
The methods are, of course, identical down to the
extractor house, which in a large plant there, a typi-
cal case, contains 198 tubs, each 2 feet 4 inches high,
2 feet 1 inch in diameter at the top and 1 foot 9 inches
at the bottom. In the center of the bottom of each
tub are two small wooden cleats, 4 inches apart, on
which rests a glazed drain pipe, 4 inches diameter,
flanged end downwards. The center pipes and tubs
are filled with charcoal, coarse for 6 inches from the
bottom and medium size to within 6 inches of the top
of the center pipe, with about 3 inches outside and
5 inches inside the tub of coarse charcoal again.
On the top of the charcoal, in the tub itself, i. e., all
round the pipe, is a wooden lid to keep the charcoal
from floating and blocking up the outlet pipe.
Another form of filter tub much used has no cen-
ter pipe, but there is a false bottom covered with a
filter cloth, above which is charcoal, and on top a
hinged lid, kept locked, with the feed pipe led into it.
The solution leaves the tub under the false bottom by
means of a siphon pipe to the next tub.
The preparation of the charcoal is important. Im-
purities are prejudicial and wasteful. Fine stuff is ob-
jectionable, as it will pass through the sumps with
the solutions (and, incidentally, decompose the KCy),
besides making a bad filtering medium when closely
packed. Heavy, compact charcoal, again, is not
nearly so efficient as that which is soft and porous.
Gold is deposited throughout the whole of light char-
coal, so that compact material offers far less surface.
Moreover, it would take longer to incinerate. Ac-
cordingly the charcoal is ground and sieved to three
sizes : coarse (about A-inch), medium and fine, which
last is straightway rejected. The other sizes are
thrown into separate tanks of water and washed ;
the compact coal sinks, the light, porous stuff of both
sizes is skimmed off and allowed to dry before being
used. About 30% of the original quantity of charcoal
is lost by this treatment.
The tubs in these works are arranged in two
groups, the first of 144 filters, in twenty-four sets of
six each for strong solution, and the second of fifty-
four filters, in eighteen sets of three each for alkaline
wash (containing 0.04% KCy) and weak solution.
The solution passing through a 1-inch branch from
a 3-inch main travels down the center pipe of the top
filter in each set, coming up on the outside over the
lid, and through another 1-inch pipe to the second
filter, and so on, finally passing away by an iron-lined
launder (a tile lining would be better) to its own par-
ticular sump, whether alkaline, strong or weak. The
top of each of the last five filters of a set is placed 3
inches lower than the top of the preceding one. The
top filter naturally catches most gold, and when
fairly charged is removed, and each of the remaining
five tubs of the set is moved up one step, bringing
second filter into first place, a tub with fresh char-
coal being put into sixth position. The filter removed
is relieved of some of its solution (to save loss during
moving), and emptied into a large box with a filter
bottom, when what solution there is in the tub drains
away to the strong solution sump, leaving the aurifer-
ous charcoal ready to be shovelled out and taken to
the furnace room. Every day eight top-strong solu-
tion filters are emptied in this way, so that a tub oc-
cupies first position during three days. The flow of
solution from the intermediary tanks to the filters is
regulated by valves in the main, and an ingenious ar-
rangement prevents that flow being exceeded. At
the junctions of the mains with the distributing pipe
a small open glass tube is inserted, in which the solu-
tion under the right pressure rises to a certain
height. A very slight excess over the proper pres-
sure will cause this tube to overflow, obliging the at-
tendant to pay strict attention to the amount of solu-
tion he allows to pass through.
The absence of iron in the filter tubs constitutes a
slight advantage over zinc boxes, where the iron
sieves at any rate do not improve the solutions.
The launders from the filters are connected with
all the sumps, so that, if necessary, any one solution
can be passed over the whole of the filters, but as a
rule the filters are worked in two groups, as shown
above, and then about 400 gallons of strong solution
per hour pass through 144 tubs, and 300 gallons of
weak or alkaline through 54 tubs.
The efficiency of the precipitation of the gold by
the charcoal is of course an important point. Zinc
does not seem to act rapidly enough, or, indeed, quite
effectually, on very dilute solutions, whence arose the
usefulness of the Siemens-Halske and other electro-
lytic processes, but with charcoal the strength of so-
lution does not seem to affect the percentage of pre-
cipitation at all, which remains uniformly high. At
one large works the solutions going out into the
launders from the tubs rarely show more that 33
grains gold per ton. Solutions down to 0.04% KCy
are successfully precipitated at this establishment.
The gold caught by the top filter of a set is consid-
erably purer than that caught in the lower ones.
Frequent tests show this to be quite characteristic,
steady diminution in the value of the gold taking
place downwards through a set, till in the bottom tub
it is nearly pure silver. However, as the filters are
shifted from the bottom upwards, they all contain
about the same quality gold when burnt.
The reason for this peculiarity is, no doubt, owing
to the gold being precipitated first and other metals
afterwards.
No doubt experiments might be usefully made as to
the desirability and economy of keeping the contents
of the top filter separate from the rest, as contain-
ing very pure bullion, requiring little or no refining.
With six filters in each strong solution set, the two
top filters might be allowed to remain stationary un-
til well charged, the "step-up" process being con-
fined to the lower four.
The exact action of the charcoal has, so far as the
writer knows, never been experimentally demon-
strated. Rose, discussing the question in connection
with its use in the chlorination process, states that
the prevailing opinion is that the hydrogen and hy-
drocarbons remaining in the charcoal are the active
agents in the precipitation. No doubt this would ap-
ply also in precipitation from cyanide solutions, the
result being the formation of hydrocyanic acid and
free gold. This HCn itself represents a certain
amount of loss of an active agent.
It is an accepted fact that the prolonged contact
of cyanide solutions with charcoal causes a loss of
cyanogen. This undesirable condition obviously ob-
tains, as the same solution (of course strengthened as
and when required) circulates for months between the
leaching vats and the filters.
Park instances the case of the Kapai- Vermont
Works, New Zealand, where the ore was kiln-dried
before being sent to the pulverizers. Here it paid to
employ labor to pick out the lumps of charcoal and
partially carbonized wood rather than sustain the
loss of cyanide (and gold, also, in the leaching vats),
which neglect of this precaution involved.
In the daily trials of the solutions the loss from this
cause would not seem to be great. In one case where
a 0.25% strong solution is used, it titrates 0.11% after
use, and the major part of the 0.14% difference must
be accounted for by the gold dissolved.
From the filter house the auriferous charcoal is
conveyed to the furnace room. At the same works,
whose extractor plant has been described, there are
four reverberatory furnaces, each 10 feet long. The
charcoal is charged in through side doors, of which
there are six to each furnace, each perforated with a
number of holes to admit air to assist in burning off
the carbon. The furnaces are arranged in pairs,
with a stack to each pair. When charged, a wood
fire is lighted in the firebox until the charcoal is well
alight, when the dampers are closed and it is allowed
to slowly burn itself out. This it does not do com-
pletely, so it is sieved in a trommel of 900-mesh, con-
tained in an iron box, what remains in the trommel
being returned to the furnace with the next charge.
The fine stuff in the box is called "ash." Every
twelve pounds of ash carries from nine to ten ounces
of gold. This ash is mixed with borax (in the propor-
tion of three parts borax to one and a half ash, with
one of dried and washed tailings, when the ash is al-
kaline), and smelted in graphite crucibles. The pots
are filled and placed in the furnace, the slag skimmed
from time to time, and fresh charges of " ash" added,
till sufficient gold has accumulated in one pot, or the
latter shows signs of wear, when it is poured into a
mould. It is certain that some appreciable loss must
take place during this operation, owing to the numer-
ous small quantities of valuable ash which are dealt
with. Some of the stuff is almost impalpable dust.
When charging redhot crucibles, it is apparent that
many fine articles are carried away by the expansion
of air in the neighborhood of the crucible.
In spite of some very strong points in its favor, it
is doubtful if these are sufficient to cause the char-
coal method to supersede the better-known zinc pro-
cess. The writer thinks that the following advan-
tages deserve careful consideration : (1) A high-class
bullion is produced. One well-known mine there re-
ceives $19.45 per ounce for its cyanide gold. At any
rate the bullion does not have a detrimental constitu-
ent, such as zinc, introduced into it by the necessities
of the method used, and is of a nature easily refinable.
(2) The percentage of the precipitation extraction is
high ; and this is, so far as the writer knows, regard-
less of the strength of the solution. (3) In spite of the
large quantity of auriferous charcoal to be dealt with,
a great part of the waste in it is so easily got rid of
(by simply letting it burn itself out), and the resultant
" ash " is so directly and easily smeltable, that this
disadvantage is almost, if not quite, counterbalanced.
There is no necessity, as with zinc slimes, for careful
oxidizing roasts (with some unavoidable loss), or
treatment with strong acids.
The one great disadvantage of the method seems to
be the greater chance of loss through the immense
bulk of stuff handled, and higher cost of the operation
itself. Minor points are a somewhat greater outlay
for plant and buildings. The effects of the decompo-
sition of the solutions by the charcoal have not yet
been very well defined.
At one of the large Australian works, 700 ounces of
gold are deposited per month on 10,000 pounds weight
of charcoal. W. M. Davis, in the chlorination pro-
cess, found that 240 parts of charcoal were required
for the precipitation of 19} parts of gold. It will be
seen that the proportion is about the same as with
cyanide solutions.
Theoretically, one ounce of zinc should precipitate
six ounces of gold, but in practice, from four to twelve
ounces of zinc are required for every ounce of gold.
Allowing eight ounces Zn for one ounce Au, 350
pounds Zn would be required to precipitate 700 I
ounces of gold. The cost of charcoal precipitation
works out (with charcoal sold at 9d for forty pounds)
at 4.29d per ounce of gold, or, at these works, 0.545d I
per ton of stuff treated. Zinc precipitation (with Zn
at 4Jd per pound) would cost 2.25d per ounce of gold,
or 0.275d per ton of stuff. The labor necessary must
also be considered. In these works two men at 7s
each per diem are kept constantly employed in the
extractor house. This works out at 0.760d per ton of
stuff treated. With zinc extractors the work could
be done by the foreman, or even allowing one man at
7s the cost would be reduced by half, that is, to 0.382
per ton.
To recover the gold from the charcoal " ash " costs I
at these works Is per ounce of bullion 900 fine, exclu- i
sive of labor. This is accounted for by the large |
quantity of stuff to be smelted, with a consequent :
large expense for fluxes, fuel and pots. In some i
works in New Zealand and South Africa, the cost of i
the recovery of the gold from zinc slimes is as low as ij
2d per ounce, though probably it would not average \
more than 800 fine.
This particular item does not of course make much !
difference when spread over a number of tons of low- i
grade ore, for the total cost at this particular plant,
with cyanide at Is 2d per pound, is only 2s 3d per ton. i
Considering these works particularly with refer-
ence to loss through the large bulk of stuff frequently
handled, we see 10,000 pounds of charcoal transferred
from 208 filters (i. e., eight filters per day twenty-six
days a month) to the draining box, divided among
four furnaces for incinerating, and finally smelted in
charges of not less than twelve to fifteen pounds.
There remain the questions of increased outlay for
plant and buildings, but these are not very serious.
Still considering the same works, each filter tub
costs 25s complete, so that the whole 198 cost £247
10s. Zinc extractors of the necessary capacity, with
trays, steel side launders, etc., cost £60.
Some expense on this head might be saved by the
substitution of large shallow wooden tanks, such as
are in use at the Mount Morgan chlorination works,
though perhaps the thorough contact between the
solution and the charcoal which is most favorable to
successful precipitation would not take place in them
as well as in the numerous small tubs.
The area of the building occupied by the filters and
connections is fully 1000 square feet. Zinc boxes
would require but a small portion of this.
Colorado Smelting Methods.*
Written by Jas. L. Hodoes.
The Omaha & Grant Smelting Works at Durango,
Colo. , draws its supply of ore from all parts of the
southern counties. At no other point in Colorado is
the metallurgical problem quite so complicated as at
this smelter. Large percentages of zinc, arsenic,
copper and antimony are continuously present, and a
very large proportion of the ore supply is received
at the smelter in the form of concentrates, which
have to be specially handled. The principal advances
in smelter work have been in the line of mechanical
improvements. Any device which shortens time in
the preparation of the ore for the furnaces or lessens
labor at some point at once becomes a factor in the
economical treatment of the ore. A number of such
factors have been introduced, some very interesting.
Beginning at the roasting furnaces : As fast as
possible the fireboxes are being altered from the old
method of direct coal burning furnaces to gas pro-
ducers. The air is forced under the grates by a
moderate pressure from a steam jet at each end of
the firebox, the steam acting as an injector. A
much poorer grade of coal can be used by this method
of combustion. Instead of " slag roasting " the ores
in these furnaces, the finish is given as a sinter roast,
requiring much less heat than in slagging the ore,

abor in crushing the Blagged ore. At the slag tap
■f the furnace another improvement baa been fntro-
luced, made possible here because of the topograph;
if the ground on which the Bmelter is built. At the
oot of the slat' dump Bows the Animas river,
later from which is forced by powerful pumps to a
loint just below the level of the working Boor of the
urnace. As the slag runs out from a large Beparal -
as box, instead of into a Blag pot, to be hauled away,
t is allowed to fall through a hole in the iron floor
nto a launder, at tin- end of which is a pipe convey-
Ig a Stream Of water, under pressure from the pump
ibove mentioned, which hits the stream of molten
lag almost at right angles, and instantaneously sliv-
rstheslag int.. a granulated condition. The same
tream which granulates the slag carries it by its
tree down the launder and deposits it in the Animas
i\er. to be carried away. Experiments have shown
bat this granulated slag, owing to its extremely
harp edges, makes an admirable sand for mortar.

rranged, so that it can be drawn away from the
[urnace by a cable attached to a hoisting engine, and

dense water, and you will note in the picture I send, a
long pipe running up the hill. This is the pipe which
condenses the steam, and the exhaust from the en-

and they use when running steady only about 500
gallons of water per day. By condensing the steam
they get a superior quality of water.
The Copper Queen people arc adding another
Smelter to their already large plant. The new first-

Silver Smelting in Mexico.*
NUMBER VI.
m.
In the case of excessive iron reduction, zincy matte
segregates from iron matte, and, owing to its spongy
condition and low specific gravity, floats on top of
the slag, carrying sulphide of silver along, which ac-
counts for the silver value of the slag. It is known
that metallic iron decomposes sulphide of zinc and
also sulphide of copper to some extent, but these re-
actions are never absolute, which explains the ex-
istence of zinc in the matte and of copper in the lead
bullion. Cuprous sulphide, however, has the prop-
erly to fuse together with zinc sulphide, and thus
carry it into the matte, thereby cleansing the slag.
This fact is made use of in cases where the lead per-
centage of the charge is insufficient to cover the
silver. Sulphide of lead does not combine with zinc
sulphide; it is, therefore, useless to increase the spe-
cific gravity of the matte, on that account, by driv-
ing lead into it.
Most smelters carry now enough copper on their
charge to produce a first matte of from 8% to 12% of
copper. To go beyond that is inexpedient, on ac-
count of the difficulty of keeping the syphon tap open.
This difficulty renders the constant use of sledge and
bar necessary — an operation which wears out and
scares off the workmen.
The copious production of speiss is another sign of
excessive reduction, hence unnecessary consumption
of fuel. By continued cutting down of the fuel, a
point will be reached when the production of speiss
will cease altogether, and the matte will run up in

lead. The bullion will deteriorate by taking up that
arsenic which is not volatilized as arsenious anhy-
dride or arsenious trisulphide. At the same time a
copper speiss may be formed, which will incrustate
the hearth and clog the syphon tap. The slag will
also run up in lead, if not in silver. It is a matter of
good judgment then to know how far it is prudent to
go. I do not think it will pay to run the matte
higher up in lead than 18%. A higher grade matte
is also difficult to roast well. In order not to miss
the proper point, it is necessary to take frequent
samples of the matte — at any rate one a day from
each furnace — assay them and regulate the fuel.
The cutting down of the fuel necessitates the rais-
ing of the blast, but this must not be exaggerated,
otherwise the heat will rise to the top, the hearth
will soon be chilled, and the furnace run slower.
If speiss be produced, it may be added to the ore
charge again, when most of the arsenic will go off as
sulphide by entering into union with the sulphur of
the sulphides present. In the concentration of matte
there is always some copper speiss obtained, which
has probably been in mechanical admixture with the
matte. Though copper speiss, if in large lumps, is
hard to break, even by a drop weight, still, if re-
smelted in conjunction with sulphides, a foliated speiss
with a reduced percentage of copper will result,
which can be passed through rolls, if it is desired to

roast it, in conjunction with sulphides, or broken with
a hammer for addition to the charge.
Coke containing much gaseous matter will also re-
sist reduction, oven if added in excess. In this case
the use of mixed fuel, i. e., charcoal and coke, is ad-
visable. Fluorspar, which is not often found associ-
ated with Mexican ores, acts like cuprous sulphide on
zincy matte, only in a different way. It renders the
slag so hot and liquid that the zincy matte remains
with the iron matte, and does not segregate as in the
case of a slag of a lower temperature. One mine
which produced ores with fluorspar gangue in notable
quantities was the Veta Grande, near Parral, Chi-
huahua. Such ore permits a considerable reduction
in fuel, and is also beneficial in the treatment of ores
carrying barite. The separation of matte, speiss
and slag, which are tapped intermittently from the
furnace, is effected in a cast iron matte or overflow
pot, and more frequently called settler, which is
mounted on a carriage and placed under the flag
spout. It is of conical shape, hemispherical towards
the bottom, and measures 3b' inches diameter at top
by 22 inches in depth. It weighs over K00 pounds and
holds about 580 pounds of matte and slag.
Matte, speiss and lead, if any, will sink to the bot-
tom of the pot and separate there in strata, in the
order of their specific gravities; while the slag, with
the exception of the chilled crust serving as a cover
for the matte, will overflow through a spot attached
to the settler into a smaller pot — the slag pot — made
of cast steel and also mounted on a carriage. When
filled, this pot is removed, replaced by an empty one
and allowed to cool down for a few minutes until top
of slag is black. It is then taken to a dumping pit,
where a workman, called the " picador," punches two
holes in the top crust — one in front and one in the
back — when it is emptied by the pot puller into large
pots underneath, the slag running out from the front
hole, while the gases escape through the other. The
shells are saved for resmelting. This method is im-
perfect, but the use of the Devereux pot of the small
dimensions, as they are locally made imperative,
caused too much loss of time and had to be abandoned.
The dumping pits are located between two slag hills,
which were built up in an evil hour in front of and in
too close proximity to the furnace shed. It is 3 feet
4{ inches deep, 6 feet 4 inches wide and 12 feet long,
and is covered over with heavy cast iron plates, in
the lengthwise center line of which a slot is left wide
enough to pour slag from both sides into the pots un-
derneath. There is room for four pots, so that eight
slag pots may be emptied simultaneously into them.
Each of these large pots — twin pots or double dump-
ing pots, so called — is resting in a rotatable frame
attached to a railway truck, a device which is pat-
ented by the Colorado Iron Works, Denver, and
known as the Nesmith truck,
on, A railway track of 36-inch
gauge extends from the pit on
an ascending grade to the
edge of the slag dump, so that
the pots when filled may be
hauled by a 7xl2-inch locomo-
tive and emptied. The shells
from these pots are not saved.
As soon as the locomotive has
taken out a load, another set
of trucks is let down into the
pit by gravity and is being
filled.
A locomotive, two of which
are used alternately, con-
sumes twenty-one tons of an-
thracite coal a month, and re-
quires one driver, one switch-
man, one pot washer and one
dumper per twelve-hour shift,
whose wages amount to $8.75,
or $17.50 in twenty-four hours.
The dumping pit gives con-
siderable trouble in the rainy
season, when it is frequently submerged.
The slag samples are taken twice a day from each
furnace and granulated. The slag of each furnace is
assayed separately, but an analysis is made only once
a day of a mixture of the granulations of all the fur-
naces running on the same charge, except in special
cases.
The shells from the slag pots are dumped into a
buggy standing in a pit and hoisted by an electric
elevator to the top of the slag hill, whence they are
taken over a bridge to the charge floor. The settlers
are also hoisted by another elevator to the top of the
same slag hill, and emptied when cold. The matte
cones of each furnace and each shift are kept to-
gether in one place and marked with the number' of
the furnace, so as to have a check on the work of the
men. When cold, the slag is separated from matte
and speiss, broken up and wheeled across a bridge
to the furnaces. The matte is broken up and
speiss is picked off, as much as possible, weighed,
and put on the heap of the respective month. This is
done to get an idea of the daily production of matte
and speiss. The matte is wetted every day by turn-
ing on a stream of water from a hose. By this ar-
rangement the matte weathers, crumbles up and can
then be easily separated from the speiss. At con-
venient intervals, it is trammed over a bridge con-
necting the slag hill with the charge floor to another
bridge connecting the charge floor with the sample,

mill, and run through a ball pulverizer. The ground
material is weighed and sampled before it goes to the
oaleiners.
The speiss is either returned to the furnaces, or, if
not convenient, held in reserve. An analysis of 1482
tons of speiss showed as follows : Pe 71.6, As 15.6,
S 5.5, Cu 1.2, Pb 3.5, not determined 2.6; total,
100. Silver contents, 14.3 ounces per 2000-pound ton;
gold contents, 0.08 ounces per 2000-pound ton.
This speiss shows excessive reduction of iron ; it
should not have contained more than 60% of iron. It
is apt to cause incrustations in the hearth, and, while
liquid, it is intensely hot, imparting its heat to the
settler, which appears white-hot at the bottom. It
always carries lead-bullion along mechanically, and
adheres tenaciously to the cast iron pot, so that fre-
quently it had to be chiseled out, an operation which
is attended by great breakage of pots and loss of
time. The metallic lead also contributes to the
" sticking of the pots " when solidified. If lead should
go into the settler in quantity, as is the case when a
furnace is not working well, it becomes necessary to
pour it off into smaller pots as soon as matte and
speiss have hardened sufficiently to permit this pro-
cedure. At smelter No. 2 they use a tap-hole near
the bottom of the settler, at its back, with a spout
attached to it, to tap off matte, speiss and lead into a
flat, troughlike vessel on wheels standing in a pit.
This arrangement has not given satisfaction at
smelter No. 3, on account of the rapid widening out
of the tap-hole by corrosion, and the frequent break-
ing off of the spout during the removal of the settler
to the top of the slag hill. In the measure in which
the matte approaches the stage of copper matte, it
acts like the above speiss ; the settler pots become
" sticky," and require much hammering to get the
matte cones detached. They also require cooling
with water. The settlers were changed ordinarily
every li hours; but when the matte fall increased
beyond the 5% mark (5% of the weight of the ore),
they had to be changed oftener, and then the settler
men used to desert their work. In smelting much
Angangueo coarse ore, which was imperfectly roasted,
the flow of slag was so rapid that the separation of
matte was incomplete, and a good deal would run
over into the slag pot. In order to save this matte,
it then became necessary to save all the slag and
break it off when cold, thus entailing a lot of work,
which required extra men.
The application of a firebrick-lined settler of rect-
angular form, like the one in use at copper furnaces,
known under the name of Orford forehearth, would
recommend itself for such emergencies. But local
conditions forbid it. The hearths of the furnaces
were not high enough to get such a settler under the
spout, without resorting to subterranean work ; be-
sides, the working of the furnaces was not rapid
enough to keep the matte from chilling in the fore-
hearth. So the manipulation of the slag had to be
managed according to the circumstances.
The amount of slag resulting from 1000 pounds of
charge is about 60%, to which have been added 400
pounds of slag from the preceding smelting. Of the
750 tons of slag produced, 300 are smelted over again
when ten furnaces are running.
The method of separating matte and slag in vogue
at the Omaha & Grant Works, Denver, Colo., who
were in the same position as Smelter No. 3, might
have been adopted at the latter place; but, the works
being old and subject to continual repair, the firm de-
cided to rebuild them entirely.
The lead bullion from the ore furnaces is allowed to
run over continuously from the lead well into a small
cast iron pot — the cooler — which holds eight 96-pound
bars. This pot rests in a cast iron frame — the stove
— over a fireplace, so that it may be heated when the
bullion gets too cold to ladle it into molds. As the
bullion is impure, it chills very quickly; but, owing to
the want of draught, the ladlers do not use the stove.
They prefer to pour hot slag on the bullion, to thaw
it out, and afterwards to skim off the slag. The
proper way would be to tap the bullion at stated in-
tervals, as is done at some smelters in Colorado, into
the cooler, skim off the dross and mold the bullion in
one continuous series of operations. But it is next to
impossible to break the natives from a routine once
acquired.
The lead well is built up two thicknesses of brick
above the curb plates, to keep the lead as high as
possible in the crucible ; but if the furnace is run on a
reduced pressure of blast the height of the lead well
must be reduced, too, or the bullion will run out of
the slag tap.
At the matte furnace the bullion is tapped in the
old fashion, direct from the crucible into a cast iron
basin, at a point 8 inches from the top of the curb
plates. If tapped from the lowest point of the cru-
cible the tap frequently becomes so hot and soft that
sudden outbreaks will occur. On this account it is
advisable to tap the matte bullion through a tap
jacket, like slag.
The furnace bullion is, as already stated, remelted
in an annex of the furnace building. If the sole ob-
ject of this operation were to obtain adip sample of
the bullion instead of a punch sample, no exception
could be taken to it; but, as the main object is the
recovery of the copper from the bullion, the sweat-
ing process in a liquation furnace as it is carried out
at smelter No. 2, and at many refineries, is much
more preferable. Copper will separate from lead
bullion at a low temperature. If the copper dross is
then skimmed off, a great deal of lead will go me-
chanically with the dross. If the temperature is
raised to lessen the adhesion of . lead to the dross,
copper is bound to remain in the bullion. In the fol-
lowing is given an analysis of the dross skimmed at
smelter No. 3 : Pb 91.9181, Ag 0.8122, Au 0.0038,
Cu 2.8500, S 0.7598, As 2.2340, Sb 1.3400, Pe 0.0521,
Ni trace, Co trace, Bi not determined. This dross
was returned to the ore furnaces, instead of being
worked with other undesirable material in a separate
furnace.
The remelting of the furnace bullion and loading of
the cars is done by contract at $4 a carload of 400
bars. This work includes the following manipula-
tions : Tramming the bullion from the furnaces to
the remelting pots, remelting, skimming, syphoning,
cooling and numbering the bars, running them over
two weighing machines, loading them on the cars,
taking chip samples for the government assayer and
stamping the Mexican eagle on each bar, and dump-
ing the dross outside of the building. The samples
for the works are taken by an American foreman out
of the swivel pot while the bullion is running out of
the kettle. This man receives $3.25 per shift. If a
night foreman is required, he is paid $3. The
weigher, a Mexican, is paid $2 a day. The cars are
sealed with lead seals by a railway official with the
exception of one door, which is sealed by a repre-
sentative of the government assayer. No bullion car
must be removed from the smelter yard without per-
mission from the government assayer. These rules
are very strict.
The flue dust saved amounts to 1.2% of the dry
weight of the ore. Most of it is deposited, of course,
under the down-comers, and it had to be drawn out
of the dust flue, every day, into water troughs run-
ning parallel to the flue. After thorough incorpora-
tion with water, the flue dust is trammed to a wooden
platform, where it is mixed with loam from the
smelter yard and moulded into bricks by hand. When
these bricks are sufficiently air-dried they are burned
in a kiln to harden them. In this operation a partial
roasting takes places, whereby heavy clouds of
steam, sulphur dioxide and arsenious anhydrate are
emitted. The flue dust bricks are 8} inches long by
4i inches wide by 2i inches thick, and weigh, after
burning, 31 pounds apiece. The drawing, mixing
and bricking of the flue dust costs $1.25 per thou-
sand, and the setting of the kiln and burning $1.25
more. Hence a 2000-pound ton of burned flue dust
bricks costs $1.33 to make.
The handling of the flue dust, especially that from
the calciners, is very injurious to the limbs of the
workmen. By using a good bricking machine this
could be overcome, and at the same time the burning
would become unnecessary.
The average composition of the burned flue dust
brick is as follows : Si02 19.0, Pe 22.0, CaO 6.0,
Zn 2.0, S 2.4, Pb 16.2, Ag 28.6 ounces, Au 0.105
ounces.

One of the hardest things to handle through a
feeder is the crude ore as it comes from the mine —
large lumps, fine ore and medium-size rocks alto-
gether in one buueh. It is well known that it re-
quires as much power in a crusher to handle damp
sand when it packs as it does to crush the hardest
rock; and if ore as it comes from the mine is fed di-

Rand Mines During the War.
J. Klimke, ex-State Mining Engineer of the Trans-
vaal, is in London from South Africa, and to the
African Review makes interesting statement with
reference to mining operations carried on by the
Transvaal Government during the war. The Trans-
vaal Government, disapproving of his direction of
mining affairs on the Rand, offered him leave of ab-
sence for an indefinite period. He thereupon re-
signed.
The first mines to be taken over by the Transvaal
Government were the Robinson, Bonanza, Perreira
Deep and Rose Deep. Government mining inspect-
ors were put in as managers, and reported that they
had great difficulties in starting the mines. They
found that a great many repairs were necessary,
and, as nearly all the mining men had left the coun-
try, it was not easy to carry out these repairs. As
soon as they were done, however, the managers re-
vised and brought up to date the plans of each mine.
In one or two cases work had been done in the mines
which was not shown in the plans, and in these cases
the drawings were amended. Regular surveys of
the mines were carried out and the results recorded
on the plans, which constitute an accurate record of
the work done in the mines by the Boers from Octo-
ber 10 to the end of May, the period of their opera-
tion. These four Government mines were worked' en-
tirely in the interests of the Government, and in order
to profit to the fullest extent it worked the richest
stopes, did no development work whatever, and re-
duced the Kaffir wages to an average of £ 1 per
month, for the Government did not want more na-
tives on the Rand than were absolutely necessary.
In order to make the Kaffir rate of pay uniform a
notice was inserted in the Staats Courant enacting

To these totals the figures for May, the concluding
month of Boer operations, must be added. Mr.
Klimke estimates the May output of the ten mines
worked at about 60,000 ounces, of the value of
£240,000. There is also to be added the output of
the Crown Reef, which was crushing the ore from
the dumps until the end of March, and the gold ob-
tained from the plates, mortars, etc., of the non-
working mines which were cleaned by the Govern-
ment. ' ' The exact amount of the gold thus
obtained," says Mr. Klimke, " will probably never be
ascertained. Making only a moderate allowance for
these items, it will be seen that gold to the value of
£2,000,000 has been extracted by the Transvaal Gov-
ernment from the mines of the Witwatersrand. It
has paid in working costs, Mr. Klimke estimates,
about £500,000, and thus has made a profit on its
mining operations of about £1,500,000.
"Will the Transvaal Government repay the debt,
do you think ? " was asked.

rectly to the crusher, both coarse and fine, the fine
will fill the interstices between the larger boulders
and a great waste of power is the result. This power
required (that is entirely unnecessary) is very much
larger than is generally supposed. Theoretically, all
of this fine should be separated from the coarse be-
fore the coarse ore is fed to a crusher. It has been
hard to find, as I said, a feeder that will remedy this
difficulty, the ore varying from the size of a foot
square or larger down to the finest sand.
The kind of feeder, of which the accompanying is a
drawing, has been in use by me for a long time and
answers the purpose perfectly, so that every bit of
power applied to the crusher is expended in break-
ing rock and not in compressing fine material. The
feeder is fixed directly to the bin from which the
crusher is fed. The bottom of the feeder is in the
shape of a grizzly and is movable, being turned by an
eccentric which alternately moves forward and back-
ward. This allows the fine ore to pass through the
grizzly; and, as the coarser ore is moved forward,
the ore in the bin falls behind it and on the return
movement of the feeder it slips from in underneath
these coarser lumps and of course they fall off, the
amount fed at each discharge being regulated by the
gate. In practice, from the feeder to the crusher
the ore is fed over a stationary grizzly that is placed
at such an angle that all rock will run down, the
finer (if any has been left) falling through the spaces
in the grizzly. The continual forward and backward
movement of the bottom of the feeder furnishes agita-
tion enough to the ore to liberate the fine.
The pulley for the eccentric that moves this table
or grizzly is shown in the drawing.
I think the object desired and the method of doing
it is sufficiently shown in the drawings to need no ex-
tensive discussion of the pieces required.
Feeder for Crude Ore.
that every manager who paid more than £l per |
month would be fined £10 for each offense, and it also
forbade a manager to receive into his compound na-
tives from another mine under pain of a similar pen-
alty. Thus the Government was able to work
the mines at much lower working costs than had
hitherto been possible. In course of time six other
mines — the Ferreira, the Village Main Reef, the Wem-
mer, the Worcester, the Geldenhuis Estate and the
Langlaate Deep — were started working, under the
control of the companies' own managers. If these
mines were not worked in the interests of the share-
holders it was the managers' own fault. The Gov-
ernment did not interfere in any way with their
working of the mines. It only stipulated that all the
gold produced should be handed over to the State
Treasury, and in return it promised to pay all the
costs of working. It did not keep this promise, how-
ever, and has left the ten mines worked in its enter-
ests with liabilities amounting in the aggregate to
over a quarter of a million sterling. However, the
damage to the mines has been confined to the ore
actually extracted — apart from the consideration
that no development work was done — and the Gov-
ernment mines, as they are called, are in this posi-
tion to-day, that they can resume work at any time.
As regards the mines not worked in the interests of
the Government, no damage has been done to them
as far as one could see. There will certainly be some
repairs necessary — this is always unavoidable when
a mine has been closed down for any length of time —
but no damage has been done other than is natural.
With regard to the gold production, Mr. Klimke
furnished the following figures, which are claimed to
comprise the only complete and authentic return
of the results of the Transvaal Government's mining
operations yet published. The appended table cov-

press any opinion," he answered.
"Do you think it will be long before the mines are
fully at work again ? "
" In my opinion it will take at least one year after
the conclusion of the war to bring the mines into full
swing again — that is to say, to return to the average
production of the working nine months of last year."

is shown in the accompanying cut.
The telephones exhibited made a fine display and
were of those patterns sold for exchange and railway
use, as follows : No. 250, with adjustable arm trans-
mitter ; No. 200, with transmitter fitted to the lid
of the generator, or magnet box, and both finished
in walnut and oak; No. 390, designed for use at
terminal or extensions of lines, and also as a testing
instrument, if desired; No. 375, an imported Swedish
desk set, a complete telephone in itself, with gener-
ator bells and combination transmitter and receiver;
No. 213, all-nickel desk set of American pattern; No.
311, imported Swedish wall set, in both oak and wal-
nut; No. 175, wall or desk set, equally well adapted
for both uses, and easily changed from one position
to the other. There were also repeating coils, trans-
mitters, receivers, batteries, etc. The instruments
were connected up with the metallic circuit switch-
board, and the operation of the board showed the
ease with which it can be operated and how readily
and quickly the wanted connection is made. The
board is a model of beauty, and is finished perfectly
in every detail, made with metal parts in bright
brass or nickel finish, woodwork of mahogany, and all
showing the fine workmanship and handsome appear-
ance for which these well known goods are becoming
noted. While the manner in which these instruments
are finished proves very attractive to the eye, the
positive way in which they do their work, compact-
ness, and, above all, the sensitive and yet durable
transmitters and receivers retain the favorable im-
pression and confirm the many good words so fre-
quently heard with reference to the high quality of
these goods.
The company was represented by Messrs. J. F.
Hcmenway and J. A. Montague at both of the meet-
ings. ^
The Tropenas Steel Process.
Last November the Union Iron Works of San
Francisco, Cal., made its first steel casting by the
Tropenas process at their 10-ton converter at the
Potrero. This whole subject was gone into in an
illustrated article in the issue of Dec. 31, 1898.
Further technical reference is in order.
The Tropenas process consists in the use of a spe-
cial converter, into which the pig iron, melted before-
hand, is treated and converted into steel. This vessel,
like all other converters, is a sheet steel shell, lined
inside with refractory bricks or ganister. The shell
is fitted with two hollow trunnions carried on two
pedestals, so that the apparatus may be tilted ac-
cording to the requirements of the operation — i. e.,
charging the melted pig iron, pouring the steel, etc.
The inside of the converter is so arranged that the
metallic bath has a much greater depth or thickness
than in all the other pneumatic processes. It is coni-
cal for small charges and cylindrical for large ones.
Upon one of the faces of the converter, and in a plane
parallel to the axis of the trunnions, are fixed two
wind boxes, connected by a conduit to the hollow
trunnion communicating with the blowing apparatus.
These two wind boxes are entirely independent of
each other. Inside of the lower wind box a row of
horizontal tuyeres terminate. These tuyeres are
large in diameter, varying from 1} inches to 2 inches,
according to the size of the converter. They open
into the converter high enough to be always above
the surface of the metallic bath. In the upper wind
box a second row of tuyeres is placed. They are flat-
tened and their free section is equal to about three-
quarters of that of the lower tuyeres. This row of
tuyeres is placed above the lower row, the distance
varying from 4 inches to 7 inches, according to the
capacity of the converter. The upper wind box is
connected to the air main by an independent pipe,
fitted with a valve, allowing to regulate, at will, the
flow of air discharged by the top tuyeres or to sup-
press it entirely. Lastly, in the horizontal plane all
the tuyeres are so placed that they can not commu-
nicate any gyratory motion to the metallic bath.
When the melted pig iron has been run into the
converter, the latter is turned up in such a manner
as to bring the lower tuyeres near the metallic bath,
but always above it. The top tuyeres air valve is
now closed. Then blowing is commenced in this posi-
tion until the carbon flame appears. When the oper-
ation is well under way, the top tuyeres valve is
opened so as to admit through these tuyeres a sup-
plementary quantity of air, which penetrates into the
converter at a certain height above the metallic
bath. This air meets the gases escaping from the
metallic bath and burns them, thus producing a zone
of high temperature, which, by radiation, consider-
ably increases the heat of the charge. The operation
is stopped when the flame disappears. This corre-
sponds to extra soft steel. ' Recarbonization is then
made in the converter by means of a final addition,
accurately weighed, thus allowing to produce exactly
the hardness and quality of steel required.
The blast pressure required for good working
varies between three and four pounds per square
inch, according to the kind of pig iron treated. The
blast can be produced by means of a blowing engine
or by a rotary positive pressure blower.
By what has been said above it is apparent that
the characteristic features of the Tropenas process
are the following :
1. Low pressure blast, always above the surface
of the metal and through the lower or fining tuyeres.
_ Disposition of the tuyeres in the horizontal
plane, so that the jets of air, arriving above the bath,
can not impart to the latter any gyratory motion
whatever.
3. Great depth of the metallic bath, so as to avoid
the churning and stirring of the latter during the
operation.
4. Arrangements above the fining tuyeres, inde-
pendent of the latter, of a supplementary row of com-
bustion tuyeres, so as to burn the combustible gases
escaping from the metallic bath and thus increasing
the final heat of the steel.
Objection has been made to surface blowing on the
ground that a greater quantity of iron is burnt than
with bottom blowing, as in the Bessemer vessel. This
is true to a degree. During a certain period of the
operation there is a little more red-brown smoke
than in the Bessemer operation, but the loss of iron
resulting does not exceed from 1% to 1J%. The low
pressure of the blast greatly attenuates this loss,
which evidently would be much greater if the high
pressure necessary with the Bessemer process was
made use of. However, acknowledging this loss, it
is easy to account for when making out the cost
price.
On the other hand, blowing above the surface gives
a better quality of steel than some of the other pneu-
matic processes, which blow from the bottom or more
or less below the surface of the metallic bath. Dur-
ing the whole time of the Tropenas operation the
bath remains perfectly quiet, and this is entirely dif-
ferent from all the other processes, in which a con-
tinuous mixture of metal scoria and air takes place.
The steel produced by this process is purer and con-
tains hardly any gas in dissolution. The operation
being particularly quiet, there is no projection of
steel, or very little, through the neck of the con-
verter, contrarily to what occurs in the Bessemer ;
hence the saving of metal on this score compensates
for the loss of from 1% to 11% due to the greater ox-
idation resulting from blowing upon the surface.
By the use of the top tuyeres the carbonic oxide
gas arising from the metallic bath is transformed into
carbonic acid gas, thus greatly increasing the tem-
perature of the final steel without increasing the cost
price. This is accomplished by merely burning, in a
practical manner, the gases, which all the other pro-
cesses discharge, without utilizing, into the atmos-
phere.
The steel obtained being hotter, and consequently
more fluid, allows the gases to escape more easily,
and when the metal is poured into the moulds it is
perfectly quiet. Owing to its high temperature and
consequent great fluidity the pouring is much easier
and the steel produced is better utilized, as no skull
remains at the bottom of the ladles.
At the end of the Tropenas operation, before any
final addition is made, the product obtained is prac-
tically pure iron. This enables the production, cur-
rently, of a very large number of steel castings for
dynamos and other similar uses, possessing a very
great magnetic permeability, and which, when ana-
lyzed, show from 99.75% to 99.80% of pure iron.
These pieces are particularly sound, and when
machined show no blowholes or similar defects. With
the Tropenas metal, produced in such a state of pur-
ity and at such a high temperature, it is possible to
make varied final additions with the view of produc-
ing different qualities of steel, from the softest to the
hardest, and all the intermediate grades, by modify-
ing the final addition according to the product re-
quired.
The waste of metal during the operation has been
the object of special researches. The average, taken
from a great number of operations, shows that the
loss at the cupola varies between 5% and 61%. The
waste at the converter during the blow varies be-
tween 10% and 121%. The average total loss in the
cupola and converter is therefore about 17%. This
loss is not excessive when it is considered that it ap-
plies to small converters and that the pig iron gen-
erally used for manufacturing steel castings contains
from 21% to 31% of silicon.
The pig iron usually employed in the process for
manufacturing steel castings has the following
analysis:
Per cent.
Silicon 2.50 to 3.50
Manganese 0.50 to 1.25
Carbon 3.00 to 4.50
Sulphur 0.03 to 0.06
Phosphorus 0.04 to 0.06
The freer the pig iron is from sulphur and phos-
phorus the better the results. However, when the
results required are merely those needed for navy
and railroad use, ordinary Bessemer pig iron con-
taining not over sulphur 0.06 and phosphorus 0.05
can be used. When the steel produced is to be sub-
mitted to particularly severe tests, it is better to
use a pig iron as devoid as possible from sulphur and
phosphorus.
The sands necessary for making moulds are sili-
ceous sands containing a sufficient proportion of alu-
mina to give the moulds the required hardness.
All machinery castings having to be machined
upon several faces must be cast in dried moulds, also
large castings with great thicknesses. Less im-
portant castings, which slight defects (such as pin
holes, slight scale, etc.) do not render useless, are
cast in green sand moulds not dried. In the majority
of foundries using this process, a great proportion of
the castings are cast in green sand moulds not dried
or merely skin-dried. The greater part of the small
castings are cast in the same manner.
When the castings are taken out of the moulds, it
is not indispensable to reheat them. The steel as it
comes from the converter is soft and malleable. The
great majority of castings are neither reheated nor
annealed. When pieces, however, have great or un-
even thicknesses, or when they are of a great bulk,
it is preferable to reheat them for a few hours at a
cherry-red heat in an ordinary furnace, without the
use of any iron ore or other recarbouizing elements.
The object of such a reheating is to transform the
crystalline structure of pieces having great thick-
nesses into a finer grain, or to relieve the molecular
tensions due to the considerable shrinkage of steel
when the castings have a great bulk. Reheating is
also necessary when high mechanical results are to
be obtained, and principally when a great elongation
is required.
The installation of the steel process proper re-
quires, first, one or several converters, according to
the quantity of steel to be produced. Each converter
works in connection with a cupola; the latter is gen-
erally placed upon a metallic platform high enough
to allow the melted pig iron to run direct to the
cupola into the converter. The cupola is operated in
the usual manner by means of a fan or a positive
pressure blower. The air blast for the converter
can be produced by means of a rotary positive pres-
sure blower, the air pressure being only from three
to four pounds per square inch. The quantity of
compressed air required is from 22 to 25 c. m. per
minute (776 to 883 cubic feet) per ton of pig iron to
be treated. The expenditure necessary for a plant
consisting of two one-ton converters, two cupolas
and their platforms, fans and rotary positive pres-
sure blower, is about $6500, erection included. The
cost of two two-ton converters, two cupolas, plat-
forms, fans and blower is about $8500, erection in-
cluded. To this must be added the cost of a crucible
furnace for final additions, which are generally made
in a melted state. The expenditure for such a fur-
nace is a small one and does not exceed from $150 to
$200. Besides the steel-producing plant proper, the
usual foundry apparatus are necessary, such as
flasks, ladles, tumblers, reheating furnace, ovens for
drying cores, moulds and hand ladles, sand crushers
and mixers, forges for smithy, tools for cutting
headers, cranes, etc.
Each operation in the converter lasts from fifteen
to twenty minutes. Some time is required for pour-
ing the steel into the moulds and for repairing the
converter for another blow. When small pieces are
manufactured and the whole charge has to be poured
by means of hand ladles forty minutes are necessary
for a complete operation. When the pouring is made
with large ladles it requires only thirty minutes. In
the first case three operations can be made every
two hours, and four operations in the second case.
With such data it is easy to calculate what quantity
of steel can be produced when working eight hours
per day.
The converter lining lasts from 125 to 150 opera-
tions, and the tuyeres from thirty to forty opera-
tions, after which the latter must be replaced. While
this is being done the necessary patching up of the
lining is made according to requirements. If some
holes have been formed they can be plugged by means
of a mixture of cement and brick. The linings are
made with silica bricks, the cement being composed
of quartz, sand and clay.
The cost of producing the steel varies from $5 to
$6 per ton of 2200 pounds over and above the cost of
pig iron. This includes all expenses incurred at the
blowing apparatus, cupolas, labor, lining, tuyeres,
and all general expenses for the manufacture of steel
in the ladle ready to pour. These prices are the re-
sult of the accounts of works in normal operation for
several years and in which the yearly output is about
2500 tons.
Henry C. Wulf, the chemist and metallurgist of the
Union Iron Works, whose services in the above are
cordially recognized, says that for U. S. Government
requirements the phosphorus in steel is limited to
.06%. Should it contain .001% above that it is re-
jected, and in blowing it has to be constantly borne
in mind that the metal must be of a certain composi-
tion to meet the rigid physical requirements of the
Government in tensile strength, elongation, elastic
limit, reduction of area, quenching test and bending.

At Cape Nome, Alaska.
Our Nome, Alaska, special correspondent sends us
some photographs from which was engraved the
plate on the front page of this issue, which gives a
good idea of the present appearance of things in that
most northern American gold mining camp. Advices
from there received this week confirm the former
statements published herein, viz., that while the
place was originally wonderfully rich in gold, it was
worked out and overrun by experienced Klondikers
before the first shipload arrived ; that everything is
overdone and those who can are leaving.

It was not until loSti that, the want of a school of
geology at lrkut.sk made itself felt, although as far
back as the year 1843 the Department of Mines had
sent Col. Hofman to Siberia to study the gold deposits.
The information obtainable on the subject of Siberian
plaeers is scattered through a great number of mono-
graphs: and until the geological committee of the
Great Siberian railroad publishes the result of their
labors, it will be difficult to treat, the subject, com-
prehensively. In contrast with the great, strata of
the Sierra Nevada mountains in California and in
British Columbia, which belong to the pro-Tertiary
period, as attested by the volcanic mat tor with which
they are covered, the alluvia of Siberia belong to the
Quaternary epoch and are of recent formation.
Siberian placers are situated in valleys having
usually a gentle fall and often marshy. Their dis-
tinctive feature is that the pay gravel above the bed-
rock is covered, in the immense majority of cases,
with an unproductive layer of soil.
Auriferous localities are also generally character-
ized by the presence of low. rounded hills, testifying
to the intensely destructive action of the atmos-
pheric agents upon the rocky conformation of the
country. The placers are found at. a, moderate alti-
tude above sea level. In the Urals they are met with
at a height varying from 600 to 10(H) feet : in the
Alatau mountains at. 2000
feet; in the vallev of the
Olekma from 2000 to 2500
feet; and in the Yenisei from
2600 to 3000 feet.
In addition to native gold,
frequently found in nuggets.
iron pyrites, often in the
form of mispickel, and all the
products of its decomposi-
tion, such as magnetic oxide,
limonite, hematite, etc., are
met with in Siberian gravels.
Copper is found, sometimes
native, sometimes in the form
of copper pyrites; lead has
been discovered as sulphate,
carbonate, phosphate or sul-
phuret. Native bismuth has
been found in the valley of
the North Yenisei and in cer-
tain valleys of the Altai.
Among the hard stones, gar-
nets, rntile, tourmaline, zir-
con, peroxide of tin, etc.,
are found.
The organic remains are most generally those of
the mammoth. In 1S40, it was calculated that more
than 2000 of these animals were found: some, with
portions of their bodies still soft, were discovered in
the froaen clays of the extreme north. The woolly
rhinoceros (rhinoceros tichorinus) is also frequently
met with. The state of preservation of these mam-
moths animals which required abundant vegetation
— indicates, in a striking fashion, the rapidity with
which the glacial period must have enveloped the
iSt] lains of Siberia.
Human remains have also been found — a skull at a
depth of 10 feel in the Chtogolev mine in ISliO, ancient.
;s. also a stone slab, with inscriptions, in a mine
in the basin of the Kiga.s.
A feature altogether peculiar to the Siberian
placers, especially those in the district of the Lena,
,i etc, is that the soil remains perpetually frost-
bound or thaws only slightly in the summer time.
Near the sources of the rivers, places are found not
frozen; these are said to be caused by warm or tepid
springs beneath the surface of the earth.
The working of Siberia gold mines dates back only
to the middle of the eighteenth century, at which
period the first auriferous veins were discovered in
the Urals and in the government of Archangel. Cold
was discovered in the Ural mountains in 1744. Sev-
eral veins situated on the banks of the river Bere-
gofka were worked with varying success from 1800.
hi 1S:»5 the output was 13.4(V poods (70S pounds). In
;■•.! Urals the first gold reef was discovered
in 1799. The Kothkar reef vielded in 1S94 about 85
poods [3089 pounds).
Toward the close of the period 1S70-1S7!), reefs
were discovered in the government of Yenisei and the
province of Transbaikalia. In 1894-95 gold-bearing
.. were found in the district of Marunsk, in the
government of Tomsk.
In 1866 the Amur province was opened to private
trade: two years later, mining was begun on the con-
SS 9US belonging to the Upper Amur M. Co., in the
basin of the Djalinda. At the same period, explora-
- .-ere se1 on foot in the Maritime province B
in 1S71 the first gold was taken from the mines be-
._-.,- a Mr. Yetukof, in the province of Am-
Dui ag ;';.e season of 1S97 the Amgoun M. Co.
'treated V - . sa.gens of gravel, from which
about 55 poods of gold were extracted, giving an
average of 7.825 grams to a cubic meter. On the
other hand, the Amur M. Co. took out of their plaeers
poods (734 pounds), showing an average of more
than 17.06 grams to a cubic meter.-
Mr. Greener adds: "In lSftii the Government dis-
ed to the shores of the sea of Okhotsk an ex-
pedition which, according to the latest news, has
found rich alluvial drifts. There have recently ar-
rived at this port direct from the United States six
practical American miners under the auspices of the
Russo-Chinese bank. They are supplied with modern
machinery, are men of experience and go to the Yu-
men, where rich discoveries are reported. These arc
the 'original forty-niners of the New California,' and
it is hoped they will give new impetus to mining in
the Maritime province. In conversation with one of
them, who last winter prospected in the Yrukon,
Alaska, the idea was emphasized that the whole re-
gion about. Anadirski and the extreme eastern range
of the Stanovoi mountains, near Bering straits, would
prove as rich as the Cape. Nome region, since it was
of analogous formation.''
A Balanced Shaking Screen.
In the shaking screen herewith illustrated the for-
ward and backward movement, of the upper screen is
counterbalanced by the reverse movement of the
lower screen, the thrust, of the moving parts being
absorbed in the heavy countershaft. The screen
frames are so placed on rocker arms that the screen-
ing surface always moves through the true are. At
each end of the stroke the material naturally raises
slightly and is again forcibly caught, by another por-
tion of the screening surface. Favorable materials,
sand, shale, lire clay, phosphate, cement and coal,
when dry, are thoroughly screened at. the rate of fif-
teen to twenty tons per hour, and when damp at the
rate of ten to fifteen tons per hour. Dimensions:

Regarding Final Proofs.
In applications for patent the General Land Office
requires that affidavits for publication, etc., shall be
filed within a reasonable time, under penalty of for-
feiture. It having been reported thai. Register
Hobbs of the Salt Lake land office had declared thirty
days the limit when such proofs will be received,
Mr, Hobbs desires it. understood that, he has no
right, and that he would not. presume, to definitely
interpret so vague a term as " a reasonable time.''
He stated, however, that, owing to lack of prompt-
ness on the part of applicants for patents, complica-
tions have arisen which have indefinitely deferred
the issuing of patents in a large number of eases in
his office, and advises applicants to avoid unneces-
sary delay in presenting proofs. Every quibble
raised subsequent to advertising, if proof is not im-
mediately presented, undergoes the delay of investi-
gation.— Bingham. Utah. Bulletin.
Liable to Lead Poisoning.
To nil! EDITOR: — In the dry lead mines of this
county, where much of the ore is shipped to San
Francisco for reduction, lead poisoning is very com-
mon, and is well understood as one of the risks the
miner lakes in working in such mines. In some
mines water is introduced to lay the dust and lessen
the risk. I have seen many cases pronounced by
physicians to be lead poisoning, and some have resulted
in insanity so serious as to necessitate committing
the patient to the asylum, where the subject had not
been in any way connected with a smelter of any
kind. W. G. T.

September 1, 1900.
ing a company at Lawrence, Mass. A
tunnel will be started on the Lewis claim
Oct. 10th and extended into the mountain
3000 feet, cutting the old Chicago mine at
a depth of 700 feet.
SIERRA COUNTY.
The Thistle Shaft Co. has, for two
years, been boring holes on their property,
near Gibsonville, to determine the depth
of the gravel channel to tap it by a tun-
nel.
Packer & Son are engaged operating
their mine on Slate creek, near La. Porte.
They have twenty-six men in their em-
ploy.
The Ne Plus Ultra, owned by Gibson-
ville men, is bonded to Mr. Bullock, who
is driving a tunnel in the dividing ridge
between Slate creek and the south fork of
Feather river, near Newark. The tunnel
is in 3000 feet. The pay channel is ex-
pected to be reached in 1000 feet more.
SISKIYOU COUNTY.
In the French Gulch mining district is
reported the prospective sale of the New
Brunswick mine by F. Rossi to Colorado
men for $30,000.
Roberts & Jillson have ten men at work
on the Gladstone.
The Searchlight says the American
mine, owned by Baker & Hamilton, will
resume work with the 10-stamp mill.
At the Brown Bear Supt. Dobler is pro-
ceeding with the construction of the new
mill.
STANISLAUS COUNTY.
The Stanislaus M. & P. Co. has the ma-
chinery for its plant at Knights Ferry.
TRINITY COUNTY.
C. D. Galvin of the Shasta King mine is
successfully operating a Keystone driller
on "Weaver creek. It is thought a
dredger will be put in.
G. E. Bailey, Supt. Adele Co., Lewis-
ton, has a new mill breaking up cemented
gravel and saving free gold and handling
the black sand. The material is fed from
an ore bin into a revolving hexagon of
steel bars, broken up and the boulders
washed clean, the latter falling into a car
that carries them to the dump. The ce-
ment, gold and black sands pass through
the grate bars onto a table of riffles, with
a rapid side shake bringing the gold into
contact with the mercury in the riffles.
After leaving the table the pulp passes
through a revolving screen that separates
the coarser from the black sands. The
black sands pass on to a moving carpet
table, which cleanses them so that they
can be shipped to the smelter. The plant
has a capacity of ten tons of gravel per
hour.
TUOLUMNE COUNTY.
The Magnet hears that the Utica M.
Co. 's electric line is to be extended from
Murphys to Carters. The owners of the
Utica also own the Eureka Con. (Dead-
horse) mine near Carters.
The railway track has been completed
from Jamestown to Tuttletown. Work
has begun on the cable tramway that will
connect Tuttletown with Carson Hill.
The Boston & Tuolumne M. Co. at Big
Oak Flat has resumed operations. P.
Loefner is Supt.
There has been placed on record a trans-
fer from the Santa Ysabel G. M. Co. of
Wyoming to the Santa Ysabel G. M. Co.
of Colorado the following mining proper-
ties : Miller & Holmes, Knox & Boyle
mill and mill site, Grey Eagle quartz mine
and mill site, Wyman consolidated quartz
mine, and eighty acres of adjoining land.
Consideration $70,000. The properties lie
between Stent and Quartz.
Soulsbyville reports the discovery of a
parallel vein in the Black Oak mine. The
shaft recently reached a depth of 1000
feet. At 60 feet in a drift north of the
shaft to reach the ore shoot that had been
uncovered in the drifts above a 6-foot
drill was started in the foot wall, and be-
fore it had reached its length was found
to he in high-grade quartz. A cross-
cut opened a ledge 10 feet wide. As-
says show lowest value ore $40, high-
est $70.
Independent : At the Crystalline oper-
tions will commence at once with steam
power. Advantage will be taken at the
Republican mine of the "no water" sea-
son in extensive and needed improvements
on the property. The mill at the Raw-
hide mine is closed owing to lack of water,
the working force reduced from eighty to
twenty. The latter will be retained to
retimber and sink the main shaft from
the 1900 to the 2300-foot level. Supt.
F. F. Restano at the Golden West has
new ore discovery in a ledge 4 feet wide.
The tunnel is being retimbered, new cars,
airs and water pipes, 2000 feet steel rail
are being put in.
Jamestown Magnet: The power house
at Phoenix lake is shut down for the sea-
son, the water supply in the Tuolumne
Water Co. 's reservoirs being exhausted.
This necessitates the closing down of many
mines altogether and the reduction of the
working force in others. Including the
employes let out during the past month
by mines employing small crews, 600 men
who work in either mine or mill find
themselves out of employment temporarily
by the giving out of the water supply.
At the Jumper Syndicate's mines about
thirty-five men have been drafted, prin-
cipally at the Golden Rule mine. They
have hung up twenty stamps in the
Jumper mill. It is the intention of the
superintendent to keep forty stamps in
operation as long as they have battery
water, using their own electric power and
steam to operate by. At the App Con.
Co. 's properties about forty men are re-
tained, some sixty being let out. This
company had everything in readiness for
the shut-down. At the Rawhide they
have commenced retimbering the shaft.
When this is finished, sinking below the
1700 level will be resumed. At the Har-
vard the force has been reduced from
sixty-five to sixteen men, who are doing
development work at 5 and 7 levels.
The Black Oak people will continue to
operate their 30-stamp mill right along,
using steam power. On the cessation of
the water supply, the Dutch mine closed
down entirely, in the absence of Supt.
Trittenbach. On his return, he stated
that ten stamps will be kept in operation
as long as the battery water lasts. About
fifteen men will be employed about the
mine. About forty men were laid off at
the Golden Gate mine, only sixteen being
retained. The chlorination works at this
property are still in operation. Seventy
men were laid off at the Eagle-Shawmut
mine as a result of the giving out of the
water supply and closing down of the mill.
About forty men are kept on. During
the shut-down the mill will be overhauled
and some changes made.
COLORADO.
BOULDER COUNTY.
At the Lucky Star R. A. Duncan re-
ports that in sinking 100 feet enough ore
was taken out to pay $2500 over the ex-
penses of the work.
CLEAR CREEK COUNTY.
Georgetown reports that the Doric gold
mine has started up again and will be
worked under the management of an Eng-
lish expert, who has been sent over here
to take charge of the development work
by the London shareholders.
An extensive power plant is being intro-
duced at the Griffith mine by the Annetta
Co.
The Sedgwick mine, on Covode moun-
tain, is reported to yield values of $35 per
ton in gold, silver and copper. A. Harley,
one of the principal owners, is in charge
of operations.
The Silver Glance mine, Democrat
mountain, is under bond and lease to
G. Berg & Co., with whom is associated
J. H. Robeson, manager Pelican Dives
and Seven-Thirty mines at Silver Plume.
B. F. Kelly, at Georgetown, has a tun-
nel scheme. The idea is to run straight
into Democrat mountain 6000 feet, cutting
in its course many lodes. The first vein
will be cut within 300 feet of the mouth of
the tunnel, and it is locally calculated that
from that point on there is scarcely 100
feet on the line that is not cut by a vein.
The ore first encountered is gold, silver
and lead, running about $8 in gold, fifteen
ounces in silver and a percentage of lead.
Near the proposed terminus of the tunnel
the ore is high grade silver, many of the
mines having ore which runs 400 ounces a
ton. The advantage to these silver mines
is that, owing to the decayed condition of
their workings, new shafts are inoperative
if worked from the surface, and the tunnel
can be run the entire 6000 feet about as
cheaply as a single shaft can be sunk to
the depth of the tunnel. A feature of the
contract with the property owners is that,
if for any reason they do not see fit to
work veins on their property that may be
cut by the tunnel, Mr. Kelly has the right
to work these veins on a five-year lease.
In connection with the tunnel scheme it is
the intention of Mr. Kelly to construct a
mill at the mouth of the tunnel for the
treatment of the low grade ores that may
be encountered. This enterprise will not
be started until the tunnel has cut a suf-
ficient number of ore bodies to guarantee
a sufficient supply of ore for a large plant.
The Wilcox tunnel, owned by the
Miami M. & M. Co., has been sold to the
Big Five M. Co.; W. D. Daniels, Denver,
president. The tunnel is now in 2200 feet,
and will cut Quartz hill at 2000 feet depth,
perpendicular measurement. The Big
Five Co. has also bought the Turner
water right on Clear creek.
The Monarch M. M. T. T. & P. Co.
have bought the Freeland mine and about
sixty other claims, and a tunnel site from
Clear creek through Trail and Banner
mining districts to the Freeland.
The Newhouse tunnel is progressing at
the rate of 200 feet per month, and is now
in to Old Seaton, over 10,000 feet, with
about the same distance to go. The tun-
nel is 12x12 ; its destination is the 1900-foot
level of the California mine at Nevadaville.
The company has acquired the available
land opposite the tunnel, lately owned by
Hall & Co.
GILPIN COUNTY.
At the new mill at Blackhawk of the
Boston & Denver M. & M. Co., the eighty
stamps are crushing ore from the Cook,
Ridgewood and Gregory properties. An
electric motor hauls the ores from the
Cook mine to the mill, which is handling
300 tons every twenty-four hours.
An option on the East Notaway mine
has been given by Sheriff Mitchell to the
proposed purchasers for six months, at
the end of which time they are to pay
$25,000 and assume the payment of the
bond, which calls for $25,000 more in two
years.
At the Saratoga mine forty men are
employed.
The Kokomo is shipping ore to the
Rocky Mountain mill at Black Hawk.
The 76 G. M. & M. Co., through L. E.
Curtis, has sold the First Centennial min-
ing property, in Chase gulch, to the Im-
perial G. M. Co. for $50,000.
GRAND COUNTY.
The Gilsonite Co. are opening deposits
at the head of Willow creek. They find a
ready market at a good price.
GUNNISON COUNTY.
Spencer reports that the owners of the
Gunnison and Standard mines will soon
resume.
At Midway the Dale Co. is at work.
At the Elko mill J. P. Smith is in
charge, putting in tables of his own inven-
tion for concentration.
There is prospect of a smelter at Gunni-
son City. Citizens have raised $10,000
bonus and donated fifty acres of land, on
which are the remains of the old smelter.
The Colorado & Southern Railway offer
to haul ore for $1 per ton anywhere on
their line from the line of the range to the
smelter.
LAKE COUNTY.
The Yak tunnel is to be driven to the
Forest Queen property, on the summit of
Breece hill.
Leadville is to have a mining stock asso-
ciation.
The Penn mines are reported shipping
300 tons a day of siliceous ore carrying
bimetallic values.
The Miner says the bad air is being
drawn out of the Hummer shaft. In the
upper level are streaks of lead ore and
large bodies of siliceous ore. It is impos-
sible to carry a candle away from the
shaft in the bottom level ; but the air
pipes have been extended 100 feet into
this level, and it will soon be cleared to
this point.
PARK COUNTY.
(Special Correspondence). — The Boston
G. M. & M. Co., at Black mountain, are
pushing work on their Boston tunnel, de-
signed to cross all formations at a depth of
700 feet, and will be driven 1500 feet into
Hammond's Peak, with intent to tap a
body of low-grade sulphides in No. 5 shaft.
An air compressor and machine drills will
be installed next month. The property is
managed by D. G. Jewett. The tunnel is
now in 120 feet. Seven men are at pres-
ent employed.
Guffey, Aug. 20.
PITKIN- COUNTY.
During the year ending July 1 the
Argentum-Juniata, at Aspen, produced
48.287 tons, net weight, of regular (ship-
ping) ores, netting $1580.73; 6990.093 tons,
net weight, of lease ores, netting $63,-
384.67 ; 38,259 tons, gross weight, milling
ores, which produced concentrates net-
ting $151,672.56 ; aggregate net smelter re-
turns for the year, $216,637.96. The
average gross value of the ore milled dur-
ing the year was $7.36 per ton gross, in
the mine. For the timbering of stoped
ground, development workings, and in
timbering repairs, about 500,000 feet B. M.
of timber was used during the year,
largely in the form of framed sets. The
company received $14,344.59 in royalties
and charges on lease ores, 22.63% of the
net cash returns for lease shipments. The
company paid out on these ores, as royal-
ties to lessees, $2287.41, leaving $12,057.81
net income for the year from leased
ground.
PUEBLO COUNTY.
J. R. Gorden, register of the Pueblo
land office, says that for the first half of
1900 the number of mineral applications
show an increase of 33J% over the corre-
sponding period of 1899. During July
there were forty-four applications for
patents.
SAN MIGUEL COUNTY.
(Special Correspondence). — The Butter-
fly mine and mill and the Terrible mine
are now operated by the Butterfly-Terri-
ble M. Co., of which C. Bullock is presi-
dent, K. Benson vice-president, F. J.
Hobbs secretary and D. J. Sayer manager.
The upper workings of the mine are at an
elevation 1000 feet higher than the mill, a
wire rope tramway, 1300 feet in length,
connecting the lower Butterfly tunnel
with the mill. An upper, intermediate
and lower tunnel, crosscutting the forma-
tion a distance of 2100, 1010 and 1010 feet,
respectively, open three veins — the But-
terfly, Ida and Terrible. On the last
named vein a vertical shaft sinks 643 feet
from the surface, from the base of which
a 145-foot crosscut connects with the upper
tunnel. The workings on the group ag-
gregate nearly 9000 feet. The ores from
the Terrible vein consist of a sulphide,
carrying good values in silver and lead.
The Butterfly and Ida veins carry a gold
bearing ore, which is quite free milling.
The mill of thirty stamps and nine Frue
vanners is operated by a 6-foot Pelton
water wheel ; to run the latter two flumes
converge at the mill — one conveying water
from Lake fork and the other from Wil-
son creek. Only twenty stamps are now
dropping and one vanner is idle. The ore
being milled, which in the main comes
from the Butterfly and Ida veins, runs
from $9 to $10 per ton. Of the values
saved about 80% are obtained on the
amalgam plates.
Ames, Aug. 24.
(Special Correspondence). — The San
Juan G. M. Co. of Milwaukee, Wis., oper-
ates the Bessie mine and mill in Alta basin
at between 11,000 and 12,000 feet altitude,
situated between Telluride and Ophir.
The mine is opened through a main tun-
nel, running northward 1600 feet, which
affords access to two north and south
veins and two veins trending east and
west. The Bessie and Sioux veins, run-
ning north and south, are opened by
about 1700 feet of drifting, with some
stoping. The Montezuma and Baldy
veins, trending east and west, are de-
veloped by nearly 2000 feet of drifting,
with several upraises for stoping. These
veins vary in width — perhaps 2 feet would
be an average. The ore is siliceous, with
very little sulphides, and carries gold and
silver. It is conveyed to the mill over a
4200-foot Finlayson tramway line, having
twenty-two buckets of 410 pounds capacity
each. An electric motor at the mill ter-
minal attaches to the tramway machinery
to steady its motion and to stop and start
it promptly.
The mill machinery is operated by an
electric motor. The ore passes through
crushers to two sets lj-mesh rolls, thence
is elevated to automatic sampler, dropping
then into ore bins. From the bins the
material is fed to an Argall cylindrical
drier, thence elevated to three sets of
rolls, which grind to 2-mesh, 6-mesh and
10-mesh, respectively. From the rolls it
passes through a series of seven revolving
screens, graduated to different sizes, the
very fine being screened off and carried to
the pulp bins by a suction fan, the coarse
being returned to the rolls for regrinding.
Lime is mixed with the material before
grinding to counteract the effect of acid
in the ore. The ore, in this finely pulver-
ized condition, is dropped from the pulp
bins into cars, by which it is carried to
leaching tanks where cyanide solution is
applied. There are six leaching tanks,
each of 150 tons capacity. A weak solu-
tion is forced into the tanks from below
by pressure from the storage tanks.
After twenty-four hours a strong solution
is applied on top of the material in tank,
allowing it to percolate through. The so-
lution is then drawn off to the zinc boxes
by a vacuum pump.
The zinc slimes, carrying the values,
are subjected to the sulphuric acid bath,
by which the zinc is dissolved, leaving the
gold and silver in precipitate form, the
latter being dried, put into crucibles and
smelted. Some loss is said to be entailed
in the form of coarse gold, which fails to
dissolve in the cyanide. To recover it
riffles are being put in the sluiceway,
through which the refuse is washed down.
The mill capacity is about 200 tons per
day, though only about 75 tons are being
run at present.
The Alta mine is producing about thirty-
five tons of ore per day, about thirty tons
of this being concentrated at the Gold
King mill, the balance being shipped to
the smelter. An account of the develop-
ment of this property appeared in the
MINING AND SCIENTIFIC PRESS of the
issue of Aug. 11, 1900.
The Gold King mill has forty stamps.
Ten of them, with concentrators, operate
on Alta ore; the other thirty operate on
Gold King ore, which is strictly free-
milling, a very close saving being made on
the plates. About fifty tons of Gold King
ore per day are milled, which averages
close to $20 per ton. The latter mine is
worked by lessees, to whom the ground is
blocked out by the company's manager.
Alta Basin, Aug. 24. WASCOTT.
(Special Correspondence). — The Crown
Point lode, on the north side of Ophir
i canyon, is being worked under lease to
I Geo. Rohmer, who is shipping about
: thirty tons of ore per month to the Du-
! rango smelter. The main values in the
i ore are gold and silver, carried in an iron
and manganese base, the smelters allow-
ing about $2 per ton for the manganese,
bringing up the entire value to an aver-

under the management of W. J. Scontt.
The mill is not running full capacity, put-
ting through only about llKI tons Of ore
per month, which, however, is high grade,
the saviog being on the plates and in con-
centrates.
The Statsbury, located in Statsbury
basin, belongs to New York parties, who
are developing the property. Recently a
tost run of their ore was made at Suffolk
mill.
The Deadwood and Nevada group of
seven claims, limited on the northern
slop,, of Yellow mountain, is iu control of
the Milwaukee-Ophir M. Co., of which
Geo. R. Dolf is manager. This company
has a bond and lease on the old Nevada
lodo and have acquired tho claims cover-
ing the Deadwood and Mt. Vernon veins
and tho Deadwood tunnel site. Tho Ne-
vada lode was oxtensively worked in
earlier days. It trends northeast and
southwest and was opened through three
Crosscut levels. 00 to 100 feet apart, drifts
on the vein at each level having been run
1 hundred feet and the oro stoped
out between levels and to the surface. In
these old workings the vein is said to have
been from 4 to 5 feet wide. The ore on
this lode is a lead and copper sulphide,
eanying gold, silver and lead values.
Present efforts of the company aro exerted
in driving the Deadwood tunnel to cut the
Nevada lode at a point nearly 1000 feet be-
low the old workings and at a horizontal
depth of 1'JfJO feet from the entrance. Tho
work has progressed 950 feet, the tunnel
being 4Jx7 feet, with a drainage Hume be-
low the trackage. This tunnel cuts
through the Mt. Vernon vein at 175 feet
and the Deadwood vein at 400 feet from
the entrance. This company is a close
corporation, made up largely of Milwaukee
people.
The Suffolk cyanide plant, under the
management of W. E. Bennett, has just
started operating on a dump of 20,000 tons
of tailings impounded from the Suffolk
mill, which, Mr. Bennett thinks, runs
from $3 to $30 per ton. The present plant
has a capacity of twenty tons per day. If
the first run of thirty days prove as suc-
cessful as anticipated the plant is to be en-
larged to fifty tons capacity. The cyanide
solution is first forced upward through
the tank of tailings by pressure, and after-
wards poured in at the top. The zinc
precipitating boxes are so constructed as
to draw off the gold slimes at the bottom.
The Carribeau concentrating mill runs
steadily with ten stamps and four tables,
there being no amalgamating plates.
About twenty-five tons of ore per day are
reduced to five and six tons of concen-
trate. The values are gold, silver and
lead, carried in a copper, iron and lead
sulphide. The tailings from this mill are
being impounded. Wascott.
Ophir, Aug. 25.
(Special Correspondence). — The Tellu-
rite Power Co. has commenced the con-
struction of an electric power plant near
this place, which will be practically a
duplicate of their plant at Ames. The
generators at the new plant will be run
by water power, to supply which about 6
miles of pipe line will be laid.
Vance Junction, Aug. 25.
The Butterfly-Terrible mine, at Ophir,
for the three months ending Aug. 1 pro-
duced $15,946.43, the ore running $18 per
ton in gold and silver. The vein is verti-
cal. The average output is about forty
tons per day. The company is also en-
gaged in development work.
SUMMIT COUNTY.
At Kokomo Mr. Robertson has a lease
and bond on the Robert Emmett in May-
flower gulch.
The El Dorado mine, Robinson, is ship-
ping ore.
The Rattler is taking out ore which
runs 600 ounces silver per ton.
TELLER COUNTY.
At the Independence mine Supt. Stark
has resigned. Two foremen have been dis-
charged and replaced with men from Sil-
ver Plume. The duties of Supt. will for a
time be discharged by H. A. Shipman,

SEVIER COUNTY.
Near Richfield C. E. Watkins, general
manager Boston Placer M. Co., is work-
ing gold-bearing bars on the Colorado
river. He thinks he has discovered "tho
long-lost Spanish mine," 25 miles north-

of the shaft was almost covered over with
masonry. The shaft is perpendicular 30
feet, then inclines for 25 feet, perpendic-
ular again for some distance, inclines
again, and so on. Thero are ten men at
work. They have followed the opening
135 feet. The remains of drill holes indi-
cate that the excavation was made by
man. Thousands of stalactites that hang
from the walls show that ages have passed
since the work was done.

the mine will be closed Sept. 15.
BRITISH COLUMBIA.
Grand Forks reports that the B. C. Co.,
Summit Camp, have bought the water
power at Cascade. Power is being de-
veloped by the Cascade W. & L. Co. The
falls are capable of developing 10,000 H. P.
* J. P. Graves has a four-fifths interest in
the R. Bell mine, Summit Camp; purchase
price, $50,000.
In the portion of the Porcupine district,
which the provisional boundary arrange-
ment transfers from Alaska to Canada,
are about half the placer mines of the dis-
trict, which are in all yielding some
$250,000 of gold per annum at the present.
Henry Bratnober says there are gold
quartz indications and valuable deposits of
copper-gold. If the provisional boundary
arrangement should be confirmed, British
Columbia will receive an addition of new
mining country, small in area, but appar-
ently rich in gold and copper.
The fire loss at the Dundee concentrator
at Ymir is set at $11,000.
A. Laidlaw of the Standard Copper Co.
has bought a smelter site on Boundary
creek, 3 miles below Greenwood. A plant
for a 200-ton hot and cold blast standard
pyritie smelter is under construction by
the Denver Engineering Works Co. of
Denver, Colo.
At Grand Forks the Granby smelter
258
Mining and Scientific Press.
September 1, 1900.
was blown in on Aug. 21st. It has a daily
capacity of 500 tons; water power will be
used. The smelter will use 15,000 miners'
inches under a head of 45 feet. The dam
is 175 feet across the top, 75 feet from heel
to toe on the bottom, built of 12xl2-ineh
sawn timbers, filled in with rock. The
flume is 12x6 feet — a mile long. Power
was offered the Granby Co. from Bonning-
ton falls, on the Kootenai river, for $75
per horse power per year, but the com-
pany will generate its own power.
A spur track 2£ miles long runs from
the main line to the north end of the
smelter works. The power house is 1000
feet from the smelter buildings and 100
feet below them. The main power with
which the blowers, sampling works, etc.,
will be driven is to be created by a dupli-
cate set of 16-inch turbine wheels operat-
ing under an effective head of 45 feet.
These wheels are connected with the flume
by a steel intake pipe 4 feet 7 inches in
diameter. Both are directly connected
with one Westinghouse rotating arm,
alternating current generator. Another
wheel is belted to a pump with a daily ca-
pacity of 750,000 gallons. The pump will
furnish water and pressure to granulate
the slag as it runs continuously from the
furnaces.
The smelter consists of two double-
decked, steel- jacketed furnaces, 160x44
inches. The gases pass off from the top
in a 4-inch diameter down-take pipe,
which is connected with the big flue dust
chamber leading to the stack. The down-
take of the furnaces is connected with the
big flue chamber, 10x10 feet on the inside
and 300 feet in length. The stack is 11x11
feet inside measurement and 150 feet high.
The blower room is 50x58 feet, and is
12 feet from the furnace building. It will
contain three blowers — one for each fur-
nace and one in reserve. These are con-
nected with the furnace by a 54-inch di-
ameter blast pipe, all blowers being con-
nected with the one main pipe. Each of
these blowers is driven by an 88 H. P.
variable speed Westinghouse induction
motor, belted directly to the blower.
The main sampler building is 64x70 feet,
and is surrounded on three sides by ore
bins. The ore train, as it comes into the
smelter, will be carried by an incline to a
series of receiving bins parallel to the
front of the sampling works, 23 feet above
the floor and 33 feet distant. These re-
ceiving bins will have a total capacity of
1000 tons. The bins are filled directly
from the cars, which have a bottom dump.
It is intended that the matte shall be
shipped after being brought up to 45% or
50% copper. For the present it will go to
an Eastern refinery. This shipping
matte, after having been cooled, will be
crushed in one corner of the furnace build-
ing on the furnace floor. This crushed
matte will he raised by an ordinary sub-
elevator to a special matte sampler. This
matte can be sampled automatically or by
hand. The lower part contains four bins,
holding about one car of matte, and it will
contain the matte after it shall have been
sampled.
When the works are enlarged it is pro-
posed to put in a matte-converting plant
complete and to ship converted copper.
A roasting plant will also be installed.
For the present, 50% of the ore will be
roasted in piles. The treatment rate for
custom work will not exceed $5.50 per ton.

Catalogues Received.
The most striking and unique trade
catalogue received this year comes from
Arthur Koppel, 68 Broad St., New York
City. It is 10x14 inches and has a front-
page illustration that is striking in every
sense of the word. The contents are cos-
mopolitan in their character, being a de-
scription in all the principal European
languages of the mining appliances, more
especially the Koppel transportation de-
vices, .made and supplied by Arthur
Koppel of Berlin. Finely engraved views
of nearly every part of the world are pre-
sented, portraying the operation in
Europe, Asia, Africa and America of the
Koppel tramway system. The all-em-
bracing idea of such a trade album has
been well carried out in the execution.
Catalogue No. 4, third edition, and
Catalogue No. 10, third edition, published
by the Risdon Iron Works, San Fran-
cisco, are received. No. 4 treats of the
Risdon patent tangential wheel, which is
elaborately illustrated and specifically de-
scribed ; there are ten solid pages of fig-
ures, giving horse power, miners' inches,
cubic feet water per minute and revolu-
tions per minute of the Risdon water
motor and water wheel, based upon a
power efficiency of 85%. There is besides
considerable practical information of value
to users of water everywhere. No. 10 is
entirely devoted to detailed illustrated de-
scription of the pumping machinery made
by this firm, including some newly pat-
ented valve mechanism, which, like other
devices, is illustrated in sectional detail.
The usual general tables and additional
technical formulae are appended. The out-
side back cover gives a good view of the
new Risdon Iron Works ship building
plant. The Risdon now copyrights its
catalogues. The entire series comprise
seventeen handsome technical treatises on
subjects connected with all forms of mine
work.

Books Received.
"The Metallurgy of Lead," H.F.Col-
lins : octavo, pp. 368, with numerous illus-
trations. This is a companion volume to
"The Metallurgy of Silver," by the same
author, received and reviewed some
months ago, and is of equal value. Being
of later date than Hoffman's — the latest
edition of that work to hand being dated
1894 — it contains considerable up-to-date
information. It is edited by W. C. Rob-
erts-Austen, and goes at considerable
length and with great detail into Austra-
lasian practice in smelting and desilveriza-
tion. The book is a decided addition to
metallurgical literature, and, judged by
the criterion of fitness, should have
considerable sale. It is published by Chas.
Griffin & Co., Ltd., Exeter St., Strand,
London, England.

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co. 's Scien-
tific Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
LOCK.— No. 655,921. Aug. 14, 1900. P.
V. Cornils, San Francisco, Cal. This in-
vention relates to improvements in locks
for doors, and its object is to provide for a
compact lock mechanism which is con-
tainable within doors having but little
thickness. It comprises mechanism by
which the bolt may be prevented from
moving except by the use of a key ; means
by which the outside and inside knobs
may be connected or disconnected at will,
and the bolt prevented from moving over
from its locked or unlocked position. The
knob shanks are independent and act
upon the spring-pressed slidable locking
bolt which they meet transversely to its
line of travel. One of the knob shanks
has a hollow sleeve with a lug to engage
the lock bolt, and the other has a head
fitting and turnable in the sleeve with a
transversely slidable spring pressed block
adapted to engage the sleeve when
projected. Spring-pressed tumblers are
slidable longitudinally in the shank and
through an opening in the' slidable block,
said tumblers being normally held in po-
sition to retain the block within the head.
Slots are formed transversely in the tum-
blers and the key has bits so formed as to
move said tumblers through the sliding
block until the transverse slots are in line
therewith. A spring then projects the
block to engage the surrounding sleeve
and a slot or channel is formed in the key
shank, and a pin in which the key fits,
over which the slot is slidable when the
key is properly introduced.
Clutch.— No. 655,906. Aug. 14, 1900.
Joseph A. Moore, Paauhau, Hawaii. This
invention relates to a device for driving
and interrupting the movements, of ap-
paratus requiring such intermittent move-
ments. It is especially designed for the
transportation of sugar cane and the like
from points where it is collected to the
crushing rolls, but is also useful in any
connection where similar conditions occur,
and in which it is at times desirable to
temporarily interrupt the travel of the
apparatus. It consists of a drum fixed
upon the shaft to be driven, a driving
wheel, a friction wheel loosely turnable
upon the shaft contiguous to the ends of
the drum, a rope having its ends con-
nected respectively with the driving wheel .
while the intermediate portion is loosely
coiled about the drum. A frictional band
is employed and means by which it is
tightened about the wheel so that the
rope is tightened upon the drum, and
motion transmitted to it and the shaft.
Guides extend from the driving wheel
paralled to and in proximity with the sur-
face of the drum whereby the rope is re-
tained in position.
Device for Drawing Steam Beer. —
No. 656,418. Aug. 21, 1900. James O'Con-
nor, San Francisco, Cal. This invention
relates to an apparatus which is designed
for drawing liquids under pressure, such
as steam beer, etc. It consists of connec-
tions between one or more casks and a dis-
tributing chamber and connections be-
tween said chamber and a cylinder con-
taining a piston which is reciprocable
within the cylinder, so that when beer is
admitted into the cylinder, the piston will
be moved toward the opposite end until
the desired amount of beer has been ad-
mitted, which is shown by a suitable re-
cording device. The beer is drawn from
the cylinder through a discharge cock,
and the gas in the beer is so diffused and
caused to escape so that little or no foam
results when it is drawn from the cylinder.
The second cylinder in line with the first
contains a piston, a common rod connect-
ing the two pistons so that they move in
unison. A four way cock is interposed be-
tween the cylinders and the water under
pressure is brought through this cock and
allowed to enter the second cylinder while
the beer is entering the first and the cock
is then turned to allow the water to escape
from the second cylinder, and to enter the
first cylinder so as to return the piston to
its normal position after the beer has been
drawn.

Latest Harket Reports.
San Francisco, Aug. :i0, 1900.
SILVER— Per oz., Troy: London, 28|d
(standard ounce, 925 line); New York, bar
silver, 61 ic (1000 fine); San Francisco,
613c; Mexican dollars, I!
Shipments of silver to Europe during
the past two or three months have been
exceptionally heavy. The demand has
been credited to the trouble in China. A
larjre quantity of the metal will be re-
quired for the payment of foreign troops
stationed In the Par Kast.
The Loudon Financial Times, in com-
menting on the British Board of Trade
returns, says : "Tho bullion movements
are worth ;i passing reforonce. For tho
month of July the imports of "roUl and
silver declined 'from Cf>,l. '•9,000 to t'2,44ti,-
ooo, while the e i from
£1,621,000 to £2,134,000. For the Beven
months there was a decrease, in round
s, of £7,000,000 in imports, and of
Dearl] C ,000 in exports. The princi-
pal shrinkage is, of course, in the imports
from South Africa, which have dwindled
from £11,224,000 to £210,000, while tho
bulk of tho exports wont to Franco, Ger-
many, Mexico, South America and Brit-
ish India, a large increase in tho ship-
ments to the last-named country being
particularly noticeable. On the other
hand, hardly any bullion was dispatched
to the United States, notwithstanding the
heavy exports of merchandise from that
quarter, a fact which tends to show that
we are paying for our American purchases
by other methods than by cash, and we
imported from that country £\720,000
worth of bullion, as against £7,201,000 in
1*99 and £4,891,900 in the previous year."

CROWN GOLD MILLINGCO
Manufacturers of the "CROWN" CONCENTRATOR and CROWN
ORE SIZER. A dry process of sizing and concentrating ore, sand or
gravel. Designed to accord fully with the laws of specific gravity,
and especially adapted to refractory ore or localities where there is
no water.
The chief claims for the Crown Concentrator are that it occupies
less floor space and has nearly four times the capacity of any wet
concentrator; that it will concentrate ores containing base and refrac-
tory metals that ordinarily slime and carry off values; that it effects
a saving of values far above the ordinary methods of concentration.
-
We have, now in operation, a complete plant
for crushing, sizing and concentrating ores by the
Crown Dry Milling Process.
Mine owners desiring tests made can forward
us, freight prepaid, not less than 1000 lbs. nor
more than 4000 lbs. of sample, for which a
charge of $20 will be made. (This amount in-
cludes assaying, etc.)
Ores for which this process is adapted and of
which consignments are solicited are any con-
centratable ores, pulps, tailings, or sands, carry-
ing sufficient values, whether they have hereto-
fore been profitably concentrated or not.

A Money Maker in Nicaragua.
GATES IRON WORKS, CHICAGO.— Gentlemen:
MURRA GOLD MINING COMPANY, NICARAGUA, C. A.
Nicaragua, June 30, 1899.
After ane xperlence covering a period of three years with both the first and improved " Tremain Steam Stamp Mill," in every par-
ticular I havet ound it perfection— a money maker, and just the thing for a small capital, while companies organized on a large scale
would do well to look into Its merits.
I find no difficulty in crushing eight tons of ore per day and running on hard ore. This mill should be a winner.
Very truly yours,

GATES IRON WORKS, CHICAGO.— GENTLEMEN:
Our Tremain Mill is giving us good results, and although being in operation since 1892 has not cost us $1 for repairs, and to-day is
making i80 drops per minute with 95 lbs. steam pressure.
The ore we are working at present is soft and we mill in 24 hours, using No. 10 slot screen, 15 tons.
Yours truly,

Running Under Compressed Air in West Australia.
293 ST. GEORGE'S TERRACE, PERTH, W. A., February 6, 1900.
F. R. PERROT, ESQ , Agent ow Gates Iron Works, Perth, West Australia.
Dear Sir: In reply to your enquiry as to the working of the Tremain Mill on the Burbauks Grand Junction, I would state
that at the start we worked this from the boiler supplied by the Gates Iron Works Company, but owing to certain irregularities of
the running, which were in a measure due to the Intermittent supply of ore and the short time that we were able to run it per
day, I finally laid on air piping from my air compressor, a quarter of a mile distant, and used the boiler as an air receiver,
with the result that I got an absolutely constant run, which, I believe, averaged about 105 drops per minute, and this was kept up
with great regularity and showed a much better relurn in the treatment of the ore. The usual air pressure in this case was 8Ulbs,,
whereas under steam we were not so satisfied with the result as worked at 100 lbs. By this we were also saved in cost the charges ot
stoker, fuel and water, and it was worked with much greater cleanliness, and during the whole time the mill was running— which was
several months— it never froze up on us or showed any signs of "rouble in that direction.
The mill is now temporarily stopped, but when it is again s-tarted I shall most decidedly continue the use of compressed air.
Yours faithfully,
[SIGNEDl GEO. HEWER.

steam piping, it preserves the mine timbers through the absence
of moisture, and costs far less for repairs and renewals than any
other system of mine operation.

The Ideal Conveyor Belt
Is tbe one that will carry stone, ore, coal, wet or dry
material, holding buckets firmly and securely; will
stand alt kinds of exposure, and resist the heaviest
strains during a long period of service. This Is what
the LEVIATHAN HE1-T has done, and we quote the
following from a letter from tbe New York Steam Co. :
"We have used Leviathan Belting for four years, up
to *J4- inch by !vply , elevating and conveying coal. Some
of the Belting Is outside, exposed to freezing weather;
some in a steam bath. In both conditions the results
have been very gratifying, over 500 tons having been
handled In ten hours time."

THE GRI
THREE ROLLER
7VYI
The Griffin Thieo Rollor Oro Mill is a simp.y constructed Mill, suitable for working- all kinds of ores that
require uniformly fino crushing by tho wet process. This Mill is a modification of the well-known Chilian
Mill, but the rollers run upon a crushing ring or die, which is inclined inwardly at an angle of about 30degroos,
the rollors themselves also being inclined to the central shaft of the Mill, thus utilizing the centrifugal force,
as well as the weight of the rollers thomselves as a crushing agent. Tho Griffin Three Roller Ore Mill is there-
fore a Mill of great strength, and has few wearing parts. We construct these Mills with extreme care, using
only the best of raw materials, which are most carefully worked by mon who are specialists as mill builders.
We sill tho Griffin Ore Mill on its determined merits, and will gladly supply full information regarding it to
any one.

Some Modern Explosives.
Gunpowder is not a definite chemical compound
like gun cotton and lyddite, but a mixture in a state
of unstable equilibrium. On explosion six-tenths of
its weight remains in the solid form, giving rise to
the well-known dense clouds of smoke. Cordite is an
explosive that has come into wide use. It is made in
many various forms, usually in fine threads woven
into a cord. Though originally intended for small
arms, cordite has been largely employed of late in
charging heavy guns. The absence of smoke renders
its use advantageous in warfare. When fired in a
gun the time taken to consume the charge is only a
small fraction of a second. It burns in air without
explosion, but it will not burn in the absence of oxy-
gen. When placed in a confined space the combus-
tion is attended by explosive force. Cordite may be
burned under water, because the heat developed
during combustion is so excessive as to supply the
atmosphere necessary for combustion to continue.
Ballistite, a mixture of nitro-cellulose and nitro-
glycerine, is used as an explosive. It is made in
various forms, commonly in square slabs, cubes or
cylindrical tubes. Nitro-cellulose has a serious de-
fect in that when a certain pressure is attained this
substance has the remarkable property of still fur-
ther increasing that pressure. Picric acid is largely
used in the production of lyddite shell. It is fusible
and difficult to ignite, burns slowly, and is not free
from smoke. The green smoke referred to by war
correspondents is due to imperfect methods of prepa-
ration.
Of the many explosives now in use cordite is infe-
rior to none in ballistic power. In considering the
relative explosive force of one explosive with an-
other, it should be remembered that the method of
igniting has much to do with the effect, as seen in
the case of cordite. A slab of gun cotton might be
burnt in air without any other unpleasant effect than
that produced by the smoke. If, however, a few
grains of fulminate of mercury were struck smartly

Black Hills, South Dakota.— See Page 284.
in its neighborhood, an explosion would be the result.
Following is a condensed account of the use and
manner of preparation of different fulminates:
Fulminate of mercury is used for filling percussion
caps. It is prepared on a large scale by dissolving
one part of mercury in twelve of pure nitric acid of
1.36 specific gravity, and adding twelve of spirit of
wine, when a violent reaction takes place, which is
kept in check by adding gradually more alcohol.
First, the liquid becomes black by the separation of
metallic mercury, which, however, soon disappears.
When the liquid becomes cool, the fulminate of mer-
cury separates as a crystalline powder. It is nearly
Face of Ore Header in Anderson Stope, Gunnison Mine, Dakota M. & M. Co., Black Hills, South Dakota.— See Page 284.
insoluble in cold water; from a boiling solution it is
obtained in white prismatic crystals. When kindled
j in the open air, it burns away like gunpowder, but,
by percussion, it is decomposed with a violent de-
tonation. The explosion of the fulminate is so violent
and rapid that it is necessary to moderate it for per-
cussion caps. For this purpose it is mixed with
potassium nitrate or chlorate. For gun caps, potas-
sium chlorate is generally mixed with the fulminate,
and powdered glass is sometimes added to increase
the sensibility of the mixture to explosion by percus-
sion. After a little of the composition has been intro-
duced into the cap, it is made to adhere by a drop of
solution of shellac in spirit of wine, which renders it
also water-proof.
Fulminate of silver is prepared by dissolving ten
grains of pure silver at a gentle heat in seventy drops
of concentrated nitric acid of 1.42 specific gravity
and fifty drops of water. As soon as the silver is
dissolved, the heat is removed and 2000 drops of al-
cohol are added. If the action does not commence
after a short time, a very gentle heat may be applied
until effervescence begins, when the fulminate of
silver will be deposited in minute needles, and may be
further treated as in the case of fulminate of mer-
cury. When dry, the fulminate of silver must be
handled with the greatest caution, since it is exploded
far more easily than the fulminate of mercury. It
should be kept in small quantities, wrapped up sepa-
rately in paper, and placed in a pasteboard box. The
violence of its explosion renders it useless for per-
cussion caps, but it is employed in detonating
crackers.
Fulminating platinum is obtained by dissolving bin-
oxide of platinum in diluted sulphuric acid and mix-
ing the solution with an excess of ammonia, when a
black precipitate will result which detonates vio-
lently at about 400° F.
Fulminating gold is obtained as a buff-colored pre-
cipitate when ammonia is added to a solution of ter-
chloride of gold. It explodes violently when gently
heated.

bought or are about to buy mining stocks and want
an opinion as to the advisability of such purchase as
investment. Small investors are necessarily com-
pelled to depend to a great extent upon the repre-
sentations of others, and such representations are
usually made by those whose interest lies in effecting
sales. It is a favorite method among some mining
companies to capitalize, when incorporating, for
1,000,000 shares at $1 per share, par value, and then
offer the stock for from 1 to 5 cents a share.
California is given credit for originating such sys-
tem, though it would appear to be another case of
the pupil outdoing the instructor. The inception of
such enterprise is in the gambling spirit, with which
so many are imbued. A buyer of 1000 shares at 5
cents a share figures that he can not lose much
and will make big returns if "things come his
way." Usually business men forming companies for
the legitimate development of mines now endeavor to
restrict capitalization within the limit of the amount
needed for development work, and with little intent
to put stock on the market.
As a general thing the public does not care for that
kind of stock. It prefers to take a flyer in various
enterprises, and it is in deference to that sentiment
that the mining companies referred to usually capi-
talize for say $1,000,000 at $1 a share, offering the
stock at 1 to 5 cents a share. The result of the
1,000,000 shares at $1 a share sold at 5 cents a share
is about the same as having a capitalization of $50,-
000 at par. The only difference is that the latter would
have little show of general purchase, and it were
much easier to sell the 1,000,000 shares at 5 cents
than 50,000 shares at $1 a share.
The fact, too, that many a thousand shares of stock
bought at 5 cents a share has yielded the investor
from $1 to $5 a share tends to perpetuate belief in
continued possibility of such infrequent profit. The
temptation to fritter the money away realized from
the sale of 5-cent stock of ttimes overcomes the origi-
nal intent to do the work necessary to make the
prospect of sufficient value to recoup the original
purchasers or afford them any possibility of profit, so
that the first consideration would be personal belief,
justified by inquiry and knowledge, of the individual
integrity of those offering the stock for sale.
The second difficulty is the correct or intelligent
estimate of the value of a mine property — a conclu-
sion that is difficult to correctly reach on the part of
anyone. A mine may be worth $1,000,000, that is,
there may be in the limits of the claim treasure to
that amount, but if idle or unworked it might not be
worth $1000. The property might have no particu-
lar value until by judicious and systematic develop-
ment its worth were made manifest. All the great
mines of the country were once nothing but pros-
pects— some valued lightly if not wholly discredited.
Because a mine has not been developed it can not
be said that it is not contingently worth $1,000,000.
The man who buys 1000 shares of stock for 5 cents
a share, though the stock may represent at par
value $1000, must well understand that he is not get-
ting $1000 value for the $50 that he pays for the
stock. He naturally expects that development or
demand or some contingency may make his stock, for
which he pays $50, worth some greater value up to
$1000r and the fact of his buying stock shows he is
willing to take the risk involved in the purchase —
that is, pay $50 with the expectation of getting
more. Such a purchaser must know that he is
gambling on futures and must recognize the usual
percentage in favor of the game. If he wins he con-
siders himself pretty clever ; if he loses he can not
blame anybody but himself. All he can expect is that
the company shall honestly manage and faithfully
develop the property to the best of its ability. He
has a right to'expect that the company whose stock
he buys has legal title to real property. He should
not assume too much, nor take anything more for
granted than he can help. He should make his in-
quiries before instead of after purchasing the stock,
and he should never put up a cent in the purchase of
such mining stock that he could not afford to lose. If
he buys stock in a California mining corporation he is
subject to assessment, no matter what representa-
tion may be made to him. In Colorado and other
States stocks are non-assessable under the law, but
by special agreement stock in any mining company
anywhere, may be made assessable.
The mining investor in a small way should always
try to be able to make the distinction between a
gamble or flyer in mining stocks and a bona fide
investment. He should always try to remember that
a thing is usually worth what it will fetch ; that gold
is always worth $20.67 an ounce ; that brass can be
bought for less money; that if he can buy a thousand
shares of mining stock for $2.50 he must bear in
mind that that has no relation to the value of bona
fide investment in developed, paying mines.
All this is on the principle of caveat emptor : "let
the buyer beware." Meanwhile, there is probably no
form of investment more profitable than the intelli-
gent purchase of shares in a properly conducted min-
ing company. All mining prospects have a pros-
pective value, aside from any visible value of the
claim ; such prospective values being dependent upon
the location and surrounding conditions. A mine may
be worth $1000 to-day, and $100,000 to-morrow. The
rules regulating the organization of manufacturing
enterprises and the purchase of stock therein work
well in all cases, even in the purchase of mining
stock. A man can get up a scheme for manufactur-
ing a certain article and sell stock in his corporation
at an absurdly low price as compared with its par
value to those who think they can afford to take the
chances in the possibility of his success, as some con-
tingency in business conditions may occasion almost
immediate enhancement of such values.
In general it does not help the mining interests to
take a 10-foot prospect hole worth $100, incorporate
it as the Copper Gong, or the Silver Lyre, or
the Golden Monarch, for $1,000,000, and sell the
stock to unsuspecting clerks, clergymen, servants
and widows ; as such action, when ordinarily unsuc-
cessful from the point of view of the investor, helps
to keep alive the suspicion that all mining enter-
prises have a slight taint of fraud, the result being
that deserving properties often lie idle for the want
of capital, just as a fraudulent sale and failure of a
mining property hurts the surrounding districts for
years after. Mines are easily made on paper, and it
were better all around if the mine was not sold for
more than the original price of the property, with
the addition, in some cases, of a sufficient sum to put
the workings down to a certain specified depth, and
other attendant development. Then, those who se-
cured stock in that concern could have some cer-
tainty as to how the money was being expended, pro-
vided the proceeds were so judiciously placed. No
law, no advice and no amount of experience can en-
tirely prevent misrepresentation of facts or fully
compel meretricious mining companies to faithfully
expend the proceeds of treasury stock in develop-
ment. By a little judicious prior inquiry before the
purchase of stock, those who by reason of their con-
dition and surroundings know little of mining stocks
would sometimes be saved subsequent regret.
New Concentration Process.
In the issue of July 14 appeared an extended notice
of the Elmore concentration process, in which petro-
leum plays a prominent part — an entirely new de-
parture, and a proposition that from its novelty has
elicited comment.
The whole subject of concentration is justly assum-
ing such prominence in the mining world that any
proposition concerning it that seems based on scien-
tific principles is entitled to consideration. Especi-
ally is this the case in such instances where, the
originators have taken time to make experiment on a
commercial scale before announcing their claims to
public approval. The article referred to was the
substance of a paper read by C. M. Rolker before the
London Institution of Mining and Metallurgy,
and was the subject of subsequent discus-
sion, in which it was stated that at the
Glasdir mine, Wales, a practical plant had treated
fifty tons a day for over two years, with satisfactory
result; that the success or failure of the process de-
pended largely on the amount of oil lost in the opera-
tion, and that the process "acted entirely inde-
pendent of the specific gravities of the materials to
be separated." This last we consider the most novel
feature of the proposition, as, ordinarily, the differ-
ent specific gravities of the several minerals consti-
tute a most important factor in the problem of con-
centration, and if, in this case, such factor can be
eliminated, it would tend to simplify results.
It was thought through the discussion briefly
alluded to, that 80% of the Glasdir ore values could
be saved, and that before using it on an ore contain-
ing a large percentage of sulphurets the great bulk
of the sulphide material could best be separated by
ordinary concentration methods.
The inventor was present through the disoussion,
and in answer to inquiries stated that he had ob-
tained excellent results with galena ores and tellu-
rides ; with zinc ores the work was not so good ; that
he had practically confined his attention to copper
ore, but as a matter of scientific interest the oil
would "pick up" free gold, but would not pick up
metallic aluminum.
Broken Hill Proprietary.
Economical advance in mining and metallurgical
methods was shown two years ago in the annual re-
port of the Broken Hill, New South Wales, Australia,
Proprietary Co., where the average cost per ton of
ore treated had then been reduced from £6 15s 4d to
£2 3s 7d. The company's report for the six months
ending May 31st, 1900, submitted at the meeting of
the company July 27th, shows continued economical
working and magnitude of operation. During the
six months the refinery treated 16,036 tons silver-
lead bullion, the most of which was shipped to China.
The output of silver for the half year was 2,320,172
ounces fine, the price of which on the date of the re-
port was 2s 5j|d per ounce. In the same time were
produced 15,472 tons lead, at a stated price of £16
17s 6d per ton. The gross profit for the half year
was £129,576 16s 5d. Manager Delprat states that
by the improvements in the 5000-ton concentrator
there were passed through 132,165 tons ore, as
against 117,996 tons during the previous half year
" at a much reduced cost, and an increased recovery
of metallic contents." During the half year 18,035
tons ore treated in the chlorination plant gave 96
ounces gold, 213,957 ounces silver, and 178.93 tons
lead. The smelting plant treated 96,113 tons ore,
the average extraction per ton being 15.91 units lead,
20.41 ounces silver. The usual elaborate schedules of
mine costs accompany the report.

Sulphate op iron colored with Prussian blue is
sometimes sold for sulphate of copper, when it does not
contain 10% sulphate of copper. Commercial pure sul-

'98% crystallized sulphate of copper.
Taxing the net proceeds of mines has always seemed
'questionable. If Jones in January pays taxes on $5000
net proceeds of his mine, and having put that into
real estate Jones in June again pays taxes on $5000, it
would seem to entail hardship on Jones.
"Practical" men make the best "theoretical"
men ; they are more likely to have a correct "theory,"
knowing more the lines on which a correct "theory " can
he constructed. Anything that is of importance in the
mining or scientific world was once nothing but a "the-
ory " till some one with sufficient knowledge put it into
tangible, workable form.
Lands formerly in the north half of the Colville,

Since Nov. 1, 1893, the date of the repeal of the pur-
chasing clause of the Act. of July 14, 1890, the purchase
of silver bullion by the U. S. Government has been lim-
ited to the silver contained in gold deposits at the U. S.
mints, the small fraction of silver for return in fine bars,
the amount retained in payment of charges, surplus sil-
ver bullion returned by the operative officers of the mint
at the annual settlement, and mutilated domestic silver
coins purchased for the subsidiary silver coinage under
the provisions of sec. 3526, Rev. Stat.
At the works of the Bede Metal & Chemical Co., Heb-
burn, England, large quantities of copper are extracted
from pyrites cinders by the wet method, the amount
being too small to be profitably removed by the ordinary
dry processes, averaging 3% in the unburnt pyrites,
which, after being roasted, yield about 5%. The cinders
are first ground with salt and heated in muffle furnaces,
whereby the copper is converted into chloride. This is
leached out in tanks by means of acidulated water de-
rived from the gaseous products of the roasting. The
liquor obtained contains a notable quantity of silver and
a minute quantity of gold, which are precipitated by the
addition of the requisite amount of sodium iodide, and
the precipitate reduced by metallic zinc, the iodine being
thus recovered as zinc iodide. The copper is now re-
moved by the addition of scrap iron and purified bj n •
fining in the usual way. The leached pyrites residue is
in demand for steel furnaces, as it contains 70% of metal-
lic iron. For this purpose it is dried into masses of suit-
able shape.
Ip an engineer or buyer, upon seeing an analysis of a cer-
tain coal, multiplies the percentage of ash given by three,
he will have approximately the percentage of ash that that
coal will yield under a boiler. It is not always the weight
so much as the volume of ash that occasions trouble. If
the percentage of ash given in the analysis be multiplied
by five, it will about represent the percentage of ash by
volume under the average boiler. Proper maintenance
of a boiler requires that it be shut down and examined
thoroughly inside and outside at least overy throe
months.
Section 2511 of the Civil Code of California says:
An express agreement to become partnors or to share the
profits and losses of mining is not necessary to the forma-
tion or existence of a mining partnership. The relation
arises from the ownership of shares or interests in the
mine and working of the same for the purpose of extract-
ing the minerals there. Section 2516 of the Civil Code of
that State says: One of the partners in a mining part-
nership may convey his interest in the mine and business
without dissolving the partnership. The purchaser,
from the date of his purchase, becomes a member of the
partnership.
To determine the temperature of steam at different
boiler pressures, find the height of a column of mercury
due to the pressure carried; extract the 6th root — that
is, the square root of the cube root; multiply this by
177.2; subtract 100 from the product; the remainder will
be the temperature. Suppose the steam carried registers
100 pounds by the gauge, which would be 115 pounds ab-
solute pressure. To change pounds to inches of mercury
divide by .49; 115 divided by .49 = 234. The 6th root of
234 = 2.5; that multiplied by 177.2=443. That minus 100
= 343° F., the temperature of the steam at that pressure.
If tungsten were produced in sufficient quantities it
might be more largely utilized in alloying aluminum.
The alloys of aluminum and tungsten have for the past
few years been especially popular for rolled sheets and
plates to be afterwards spun. Under the trade name of
wolfram aluminum the metal has been largely used for
military equipments. The alloys of aluminum and tung-
sten can be advantageously used with the addition of cop-
per and also with the triple hardeners, tungsten, copper
and iron, or tungsten, copper and manganese. As usually
made the aluminum is hardened with some copper;
tungstate of soda and ferro-manganese are added to the
bath, making an alloy of aluminum, copper and tung-
sten, manganese and iron.
Mining for gold in gravel is a sound and reliable form
of mining investment; for, with requisite precaution, it
can be made as certain as any form of work can be ap-
proximated. Where needed surveys are made, where
the ground is thoroughly tested and the quantity and
quality of the gravel ascertained, where proper calcula-
tion is made as to needed water, power; where the proper
form of mechanism is correctly determined and the
needed capital duly provided, the proposition can have
nearly every element of risk eliminated from it, and be-
comes a simple matter of what may be considered steady
output of the finished product from the raw material, the
cost and profit as readily determined as in the case of the
manufacture of any article for which there is a constant
and unlimited demand.
Pure copper diminishes in strength as its tempera-
ture increases, and with alloys of copper and tin there is
a rapid fall in strength and elongation at temperatures
exceeding 180° to 200° O, hut in some cases the strength
is maintained up to 250° O, as is always the case with
phosphor-bronze. Aluminum bronzes between 80° and
150° C. show a sudden drop in strength, which is much
greater for cast specimens. Common brass rapidly di-
minishes in strength and elongation from 250° to 300° O,
the breaking stress at 250° C. being only 15% of the value
at ordinary temperatures. Brasses containing 1% of alu-
minum have a resistance of more than 28,000 pounds per
square inch, with considerable elongation up to 260° C.
These brasses have a higher resistance at high tempera-
tures than bronze or rolled brass. The strength of iron
and steel diminishes for temperatures between 60° and
100° O, after which it increases to its maximum at about
250° O, decreasing rapidly beyond 300° C. The reduction
in section diminishes continuously from the ordinary
temperature up to 300° or 350° C, while above 400° C. it
increases rapidly, becoming very marked at 700° or
800° C.
PURE aluminum has a specific conductivity 67% that
of pure copper. With £% of impurity the conductivity
is reduced to 61%, while with 1% impurity the conduc-
tivity is 59%. It is when are compared the castings made
in the two metals that aluminum shows to best ad-
vantage, for, although both must be alloyed with other
metals to give sound castings, the reduction in conduc-
tivity on this account is relatively greater with copper
than with aluminum. Good nickel aluminum castings
can be made having a conductivity of 45% to 50% that of
rolled copper, but it is very seldom that ordinary copper
alloy castings such as are used every day for switch
work and similar purposes exceed this figure. There is
little difference in the tensile strengths. For some time
there was a difficulty in getting good aluminum alloy
castings, but this has now practically disappeared owing
to brass founders and others having learned by experi-
ence the peculiarities of the metal. Soldering and braz-
ing, although they can be performed, are still the draw-
backs when compared with copper, but there is this to
be considered : that in most practical purposes mechani-
cal joints may be used.
The presence of aluminum has been found to lower the
point at which alloys containing it become fluid, such
alloys being fluid at lower temperatures than either gun-
metal or ordinary brass mixtures. The use of aluminum
in cheap ordinary brass mixtures has sometimes occa-
sioned the complaint that the surface of the brass cast-
ings is made black by its addition. This is due to the
sweating out of the lead from the brass mixture which
the impure brass has contained. It is not advisable to
use aluminum in brass which is to be dipped in acid, as the
aluminum, even in small quantities, makes the metal
withstand the action of the acid so completely that the
dipping is not successful. For this reason brass, which
is subject to corrosion, is found to withstand this corrosion
much better if it contains a proportion of aluminum, up
to, say 10%. The main objection to the considerable
addition of aluminum to brass is the increased shrinkage
of the alloy occasioned by the use of.the aluminum.
This ha3 to bo provided for by pouring the metal not too
hot and using large gates and risers. Aluminum brass
has an elastic limit of 30,000 pounds per square inch, and
an ultimate strength of 40,000 to 50,000 pounds, with an
elongation of 3% to 10% in 8 inches.
Sulphurous acid, or sulphur dioxide (SOj), is pre-
pared by burning sulphur in dry air or oxygen gas, or by
removing the elements of water, and an additional atom
of oxygen from sulphuric acid by heating it together
with copper chippings or mercury. The resultant gas is
purified by washing, and it is collected either by dis-
placement or over mercury. It is completely colorless,
has the overpowering odor of burning sulphur, neither
supports combustion nor respiration, is 2.247 times heav-
ier than air, is easily condensed, is liquefiable by cooling
down to 14° F., under ordinary atmospheric pressure,
and congeals into a transparent solid at temperatures be-
low 168° F. This gas deviates considerably from Boyle's
law of pressures, and occupies less space for equal incre-
ments of pressure than does air under like conditions,
this variation becoming more marked as the tempera-
ture is reduced. Sulphurous acid is extremely soluble in
water, one volume of the latter at a temperature of 50°
F. being capable of dissolving 51.38, and at 68° 36.22 vol-
umes of the former. It has a molecular weight of 65 and
a density of 32. The latent heat of vaporization of this
liquid is 182, and it boils at a temperature of 14° F. at the
tension of the atmosphere.
With a given tension of belt, nearly three times as
much power can be transmitted by a leather-covered pul-
ley as with a smooth iron surface. It is comparatively
easy to cement leather to the face of a pulley so that it
will stay for an indefinite length of time — in fact, until
the latter is worn out or it is forcibly torn from the pul-
ley. It is as easy to make such a cement joint as it would
be if cementing to wood or other porous substance. Any
good glue can be used, if suitably prepared and carefully
spread on the iron surface. For such purposes a given
amount of glue should be covered with an equal weight
of water, and the whole let stand for twenty-four hours
until the water is completely absorbed by the glue. The
mass should then be heated in a water bath until the
glue is melted. This makes a concentrated glue solution.
This is to be spread on the surface of the pulley after the
leather has been suitably prepared. A strong solution
of tannic acid should be used for moistening the leather
before it is applied to the glued surface. The solution
should be applied warm. The surface of the pulley
should be roughened by cross-filing, or the use of acid
before the glue is applied, and the glue should be warm
when the application is made. The leather used for cov-
ering pulleys may be pieces of old belting or split
leather. The size of the pulley can be increased consid-
erably by the use of the leather covering.

their intention of becoming citizens have the same rights
as citizens in Arizona Territory, Delaware, District of
Columbia, Idaho, Illinois, Indiana, Kentucky and Minne-
sota. Aliens can only hold real estate under certain con-
ditions in Iowa, Kansas, Montana, New York and Utah.
Aliens could only hold property by inheritance or collec-

been changed by act of Congress. Aliens are not per-
mitted to remain in the Indian Territory without the
permission of the Interior Department. In Washington
State aliens may hold lands containing valuable deposits
of minerals, metals, iron, coal or fireclay, and the neces-
sary land for mills and machinery to be used in the de-
velopment thereof and the manufacture of the products
therefrom ; and real estate, other than the above, can be
held on declaring intention of becoming a citizen. In
Pennsylvania aliens may buy lands not exceeding in
quantity 5000 acres, nor in net annual income $20,000,
and hold the same as citizens may. Other aliens may
take and hold, without limit, real estate acquired by
devise or descent.

The Oldest Gold mining Camp.
Written for the Mining and Scientific Press by
Theo. Van Wagenen.
Americans are accustomed to date the history of
mining in the western United States from the days of
'49 ; but, nearly half a century before that time, cop-
per mining at Santa Rita, New Mexico, was a flour-
ishing business, while thirty years back of that date
(about 1770) there was a producing gold mining camp
on the California banks of the Colorado river about 100
miles above its mouth — that is, productive from a
Mexican point of view. The region is now known —
after the rude manner of the American prospector —
as the Pot Holes, but in the olden times it was first
included in the settlement called San Dyonisius, and
later was a part of the Mission of the Concepcion. It
is no easy matter to disentangle from what remains
of the ancient Spanish records the true sequence of
events as they occurred in this part of the world
since the white men first entered it. Perhaps one
should begin with that old explorer Coronado, half
priest and half soldier, who as early as 1539-40 trav-
ersed the country from the head of the Vermillion sea
(Gulf of California) to Santa Pe, making good Indians
out of the aborigines wherever he met them, either
through baptism or the sword, as they preferred. In
this trip the dry placer districts of northern Sonora
were discovered, and also the mysterious ruins in the
Gila valley known as the Casa Grande, but it does
not appear that Coronado's trip was followed by any
attempts to colonize those parts of Arizona explored,
from which it may be safely concluded that no other
deposits of precious metals were found on the route.
So, for considerably more than 100 years following

there was peace in the desert, as far as recorded his-
tory goes.
Towards the end of the seventeenth century, how-
ever, a most indefatigable and zealous Jesuit named
Father Kino appeared on the scene. His normal
field of labor seems to have been the county now
known as Sonora and Chihuahua ; but apparently it
was not large enough for his ambition, for in 1692 he
crossed over into Arizona — which was then called
Pimeria Alta — and established a Mission in the vicin-
ity of the now flourishing city of Tucson, which he
called San Xavier del Bac. Two years later, using
this post as a base, he journeyed northward to the
Gila river, rediscovering on the way the Casa Grande
ruins, and celebrating the incident by holding a ser-
vice of the mass there. In 1697, accompanied by
twenty soldiers, thirty friendly Indians and ten re-
tainers of his own, and starting from a point in the
San Pedro valley not far from the present site of
Tombstone, he made a second trip to the Gila and ex-
plored its valley between Solomonville and Tempe.
Again, in 1699, he crossed Pimeria from Sonoita, via
Quijotoa to Gila Bend, and then working around the
north ends of the Big Horn, Eagle Tail and Castle
Dome ranges, struck the Colorado river about 20
miles above Yuma. In the following year he returned
by a slightly different route and established on the
Colorado, above the mouth of the Gila, the San
Dyonisius station. In 1701 he revisited the spot, and
after working among the Yuma Indians of the vicin-
ity took boat and followed down the stream to the
sea. His journal states that these Yumas had an
abundance of ornaments and charms of gold which
they obtained from washing the dirt of the hillsides
on the California side, just across from his newly es-
tablished post.
In 1711 the good father died without meantime hav-
ing returned to Arizona, and for a score or more of
years the field seems to have remained untitled by his
successor. In 1736, however, there was a renewal of
efforts at San Xavier, which was followed in 1736-41
by a great silver mining excitement close to the Ari-
zona line and probably not far from the existing camp
of Oro Blanco. Here the white metal was found in
planchas or "chunks" weighing up to thirty and
forty pounds. In 1750 Father Sedelmair revisited
the old outpost on the Colorado, planted by Kino in
1700. He found little left, but again his records indi-
cate the existence of a primitive gold producing in-
dustry in the vicinity. In 1771 Father Garces came
up from the south, and meeting with an encouraging
reception from the natives (Yumas and Cocopalis) he
sent Father Anza to them in 1774, who, at the upper
end of the rich alluvial plain enclosed by the great
bend of the Colorado above Yuma on the California
side, established the Mission of the Concepcion. One

may still trace the outline of its adobe walls. It
seems to have been located for the especial benefit of
the miners, for the region now called the Pot Holes
begins within a half mile of the ruins. What are left
of the records of the Mission indicate that its estab-
lishment was followed by an immigration of Mexican
miners from Sonora, who for many years worked
peacefully and in a small way alongside the Indians
on the hills. Previous to 1860 the gold won probably
went south to Altar in Sonora ; but when the United
States Government established a military post on the
river and made a stage route across the desert a pos-
sibility, American miners came in and the gold ob-
tained went to Los Angeles or San Francisco. But
there was never enough wealth in the vicinity to
maintain an active Anglo-Saxon population. Gradu-
ally the Pot Holes retrograded into the condition of a
neglected and nearly deserted camp and has re-
mained so ever since, though each year there is al-
ways a production of nuggets and dust amounting to'
a few thousand dollars in value.
Just above the Pot Holes the Colorado cuts its way
through a chain of mountains which are known on the
Arizona side as the Chocolate hills and on the Cali-
fornia side as the Picacho range. Both are simply
continuations of the San Bernardino range of south-
ern California. On the Arizona side this divide ex-
tends northeastwardly to the Bradshaws, between
Phcenix and Prescott, then bends northwesterly
around the headwaters of the Bill Williams fork, then
again northeasterly around the head of the Verde,
until it culminates in the San Francisco mountains
north of Flagstaff. On the California side the San
Bernardino bears off northwesterly, separating the
Mojave from the Colorado desert, and finally unites
with the Coast range east of Santa Barbara.
Before the Colorado cut its channel to its 'present
depth through the low point in this long divide, the
region now known as the Mojave desert, together

with a considerable area in Arizona, was a great
fresh water lake whose shore line can be easily
traced at many points, and the Colorado desert be-
low was a part of the Gulf of California. Only the
low Chocolate and Picacho ranges separated the two,
and in several of the saddles in its crest can be found
small gravel deposits richly spotted with gold, as if
at some time part or all of the outlet had passed
through them. One of these is now occupied by the
wagon road leading from the Pot Holes to the Dun-
can Flats, and from it several dry ravines fall away
to the east and southeast. The Pot Holes is the
name given to the region of these ravines, the prin-
cipal one of which is perhaps 1£ miles long and is
called Fiege gulch. All of them fall into the Colo-
rado. The prevailing rock of the locality is a dark
blue and very hard granite, intersected with several
dykes of basalt having a northeast and southwest
course, and also with numerous small veins of white
quartz, many of which are mere threads. The hill
slopes (as might be expected) are steep and very
rugged, very barren, and with but a slight cover of
soil. But on both sides of the saddle, and in it, and
wherever on the slopes bordering the ravines that
fall away from it the rugged bedrock is level enough
to hold soil, there gold can be found in pockets and
streaks and strata. Some spots have yielded hun-
dreds of dollars for a few hours' work ; others have
produced 50 cents to $1.25 per day for years. Every
winter the locality is visited by a few days of torren-
tial rain. After these are over, most of the spots al-
ready previously worked may be attacked again with
favorable results. And so it has gone on from decade
to decade.
The mouth of each ravine has been filled up by suc-
cessive overflows of the river to flat, triangular
parks. At the upper ends of these, close to the
rocky hill slopes, very many prospecting holes have
been dug from time to time in the expectation of find-
ing rich pockets of gravel on the bedrock. Some of
these have been profitable and others have not. In
most cases, the water seeping in from the river has
stopped work.
Between June 15th and September 1st the hillsides
and ravines are deserted, for human beings could not
work in the fierce heat of that season; but during
the balance of the year there are always a few score
of men at work. As no water is to be had, a form of
dry washer has been evolved in which the material is
screened and shaken and fanned until the yellow
grains are freed from the soil. The gold thus gath-
ered is coarse and angular ; probably most of the fine
dust is lost in the tailings. What is saved has all the
appearance of material that has traveled but a short
distance, if at all. Perhaps as much as $10,000 a
year comes from the district. This is not great, but
as the industry has been alive there for 100 years
certainly and perhaps much longer, the Pot Holes
have claims for consideration. It is by no means
clear whence is the source of the gold. Nuggets
worth $10 to $20 are not uncommon ; a few are
found each year. But the bulk of the output is in
grains, many of which under microscopical examina-
tion prove to be parts of crystals. The metal brings
$18.25 to $18.60 per ounce at the mint. A dredger is
now being built at Yuma which will explore the
mouths of the Pot Hole ravines.
Mine Blasting.
Written for the Mining and Scientific Press by L. J. Safley.
The firs't requisites are good materials. The fuse
should be cut somewhat according to the number of
holes fired ; for instance, for six holes, cut fuse from
21 to 36 inches, lighting the long fuses first and so on
down. If one hole or more is intended to break first,
cut fuse for the same somewhat shorter than the one
intended to fire last.
A good quality of fuse burns about 18 inches per
minute. Cut fuse somewhat with a rolling motion so
it will be straight across ; then pull the end cut be-
tween thumb and forefinger so such will be a little
smaller on end. This will then enter the cap with
facility, first noticing that there is nothing in the cap
except fulminate of mercury, in a paste-like form,
with glue or mucilage to hold the same.
To hold the cap on, if not already tight, take the
shank of a pocket knife and press on cap just where
the fuse protrudes from it, being careful not to molest
the other end with pressure, as there is more danger
with cap than powder and as much strength or more
for same quantity. If such is intended for a wet hole
draw the fuse through the hand, with some tallow or
common rosin soap in it, being careful to get some at
mouth of cap, there rubbing some in alongside of fuse.
This being done, prepare primer by opening the
end of cartridge and forcing a hard, sharp-pointed
stick the size of fuse or little larger down in the cen-
ter of powder, somewhat longer than cap, then plac-
ing the cap in the aperture with gentle force so it
will be covered by powder, doubling the end paper
back as conveniently as you can or tie string around
the same, closing powder up to the cap, making it
more impervious to water. This being done, cut off a
part of stick of powder if you do not want to use all
for a primer.
Next, having the holes clean of mud with spoon or
swab, know the length of hole ; cut one or more sticks
lengthwise, tamping one or a part at a time in hole
until you have enough to use ; then place the primer
down on last tamped and pour some loose dirt, then
tamp again, holding Qn to fuse, being careful not to
pull cap out of powder. Do not use a tamping rod too
large and especially not one of metal such as iron or
steel.
The hole being tamped full, it is now ready to blast.
The fuse sticking out several inches, split end and
hold lighted candle underneath far enough to light
and not be put out by fuse sputtering. Then skip !
In charging deeper holes it may be necessary to
spring them. This consists in hole, say, 16 feet deep
in hard rock, of putting one or more sticks of powder
down and dropping a primer on the same with an 18-
inch fuse lighted. This has a tendency to make a pot

hole at the bottom, and if not satisfactory the first
trial, to be repeated until space is large enough, tak-
ing cart after each trial to clean hole and wait until
there is no fire ; if doubtful, use a little water. The
idea is to get most of the powder together and well
confined, as by doing so it will do better execution.
Then start to load as previously stated, using 6 feet
of fuse or more and loading hole to within G or 8 feet
of surface, or according to judgment. If several holes
are to be shot together, better give all the holes the
same preliminary treatment and shoot all at once,
cutting fuse according to firing. A hole that length
and sprung that way will take about seventy sticks
of powder and should be well tamped ; taking knife
and splitting sticks will facilitate some. Giant pow-
der will generate about 6000" P. on being fired.
It is a matter of conjecture if stick containing
primer or cap should be down any great depth in
powder that is tamped, as it might set the same on
lire from fuse before exploding cap and powder.
Any number of holes may be shot on surface by do-
ing as directed (without battery), viz., splitting fuse
on end and placing giant powder in the same with a
little pressure so it will stay until lighted. Then build
B lire so as to get some fire brands; with one, or
more, light and scoot out for safety.
Mica Mining in India and the
United States.
Several varieties of mica are found in India, espe-
cially in Behar and in the Northern Circars. It
readily splits into transparent elastic flakes, and con-
sists of nearly equal parts of silica and magnesia and
about 6% lime. Slips of mica afford a convenient
substitute for platinum foil in chemical experiments
on the effect of heat on organic bodies, and they are
useful for covering photographs. Mica occurs usu-
ally in thin tabular plates or scales, resembling glass.
It is rarely crystallized in four or six-side short
prisms or long-sided pyramids. It melts before the
blowpipe into a greyish spongy glass ; it is soft, pliant
and easily scratched ; its colors are white, yellow,
brown and black ; specific gravity, 2.654. In China
mica is used medicinally. In the Northern Circars
mica mines are to be found in the upland valleys of
the Godaveri, Kistna and Vizagapatam districts.
The principal mica mines of Behar are situated on
the northern face of the Vyndhia hills, where the
three districts of Behar, Monghyr and Ramghur
meet. The most westerly mine is 37 miles southeast-
erly from Gya, in the district of Behar ; the most
easterly, 6(1 miles distant in Monghyr, the whole of
the intermediate 60 miles being more or less produc-
tive of the mineral.
In the Northern Circars, as elsewhere, the mica
reaches the surface in three different states, viz.,
the good, hard and serviceable mineral ; the soft,
wet, flimsy mineral, and the chipped and powdered
mineral. The tests as to whether the mica is good
for anything, or whether, as the natives say, "it is
alive," are its firmness, its specific gravity and the
power of reflecting the countenance free from con-
tortions, the last showing the perfect parallelism of
its individual plates and consequent likelihood to split
well. The heavier the mineral and the more perfect
the reflection the more valuable is the mineral con-
sidered. All the plates not standing the necessary
tests are of a soft and flimsy nature, without any of
the brilliant sparkle of the better sort. The natives
call this the " dead mica," and it appears to be in a
state of decay.
The plates of the superior kind are used in all the
large Gangetic cities and towns by the native
draughtsmen, by the lamp and toy makers, by the
Mohammedans for ornamenting their taziahs or ta-
boots, for ornamenting boats and umbrellas, and
making artificial flowers. The second and third
kinds are pounded and used for ornamenting toys,
pottery and the inside of houses, for sprinkling over
cloths and turbans, the sparkle from which by torch-
light resembles diamonds ; but the great consumption
of the inferior kind takes place during the Hooli fes-
tival, during which period the " abir " or pounded
mica, mixed with flour and some red coloring matter,
is freely sprinkled over the votaries of those baccha-
nalian orgies. It is the soft, shiny, scaly part of
granite and is liable to decay from constant damp.
It passes into a greasy or soapy earth or loam.
Mica is mixed with lime to form a glistening plaster
for native buildings.
The mode of opening a mica mine is as follows : A
small and convenient hill having been selected for
commencing operations upon, a party of the wild hill
tribes first propitiate the local tutelary deity by
offerings of flesh and liquor. They then ascend to the
top of the hill and commence sinking a series of pits,
the whole way down the profile of the hill, about 3
feet in diameter each and a few feet apart. These
pits are not continued vertically downwards, but in a
zigzag shape, but nevertheless not so much out of the
vertical proper as that a basket containing the min-
eral cannot be hauled up from the bottom of the pit
to the top, the zigzag Ishape of the shaft being
formed by sinking the shaft first inclining to the left
a few feet, the head of each cut or notch forming a
landing place or step, and thus the necessity of lad-
ders is obviated, the projecting of salient angles of
the notches forming a perfect flight of steps from the
top to the bottom of the pit, which seldom reaches to
a greater depth than 40 feet, when, darkness inter
fering with the workman's progress, the pit is aban-
doned and another commenced on a few feet farther
down the hill.
A slight framework of faggots, cut from neighbor-
ing trees, is placed over the mouth of each pit. On
this a man sits waiting till the signal from below is
given to haul up the basket containing the mica and
pits fill with water, and subsequent to the rains the
unhealthiness of the dense miasmatic jungles in the
neighborhood prevents the work commencing before
January.
The accompanying engravings illustrate the primi-
tive native methods of mining mica and preparing it
for market.
In the United States, as previously noted at con-
siderable length, mica is not uncommon, nearly every
part of the mineral area furnishing deposits more or
less profitable. In New .Mexico the Standard Mica
Co. operates a group of claims near the Denver &
3L&

rubbish, which has been dug from the sides of the pit
by the aid of a rude pick. On arrival at the surface
the good and bad materials are separated, the earth
and rubbish shot down the precipitous side of the
hill. The good mica, which arrives at the surface of
the pit in ragged masses about 18 inches in length
and 6 inches broad and 3 inches in thickness, after
having its ragged edges trimmed off with a reaping
Rio Grande Railway line in Rio Arriba county. They
are making regular shipments of mica to Denver and
Cleveland. Last week 60,000 pounds were shipped.
Its chief uses nowadays are for electrical purposes
and for the manufacture of wall paper. The best
mica for electric purposes is imported from India and
from Canada, the latter being a bronze mica, which
is much in favor in the industrial lines. Some of the

hook-looking instrument, is placed by itself in a heap,
and the bad or refuse — that is, the softer kind — is
also placed aside in a heap by itself.
In the Northern Circars the mines are worked by
native merchants and by at least one large European
firm of Madras. In Behar they are worked by Maha-
jans or native merchants who reside at Patna. In
northern India the excavators or miners are Banda-
tuis, or inhabitants of the hills, a race allied to the
Kols, Bheels and Santhals.
The mines, both in Behar and the Circars, are
worked during the months of January, February,
March and April only, for during the hotter months
the great heat dries up all the water for many miles
around the mines, and during the rainy season the
mica shipped from New Mexico is used for electrical
purposes, but the bulk of it is ground for the wall -
paper manufacturers. Occasionally a choice pocket
is opened that yields a high grade of sheet mica, and
this goes into the makeup of illuminated stoves and
lamp chimneys. However, there is not much profit
in this feature of the business, because of the care
that must be used in handling the mica and prepar-
ing it for market, so that the best demand for New
Mexico mica at this time comes from the wall paper
people and the manufacturers of electric appliances.
"We are in the market for good mica," says Supt.
Fleming, " all the time, anywhere. If I could con-
tract for 10,000 pounds to-day at §1 a pound I would
be glad to do so."

Some Further Mill Practice in Cyaniding the Silicious
Ores of the Black Hills, South Dakota.
Written for the Mining and Scientific Press by Jno. M. Henton.
Since writing the article on "Wet Crushing and
Cyaniding the Silicious Ores of the Black Hills of
South Dakota," which appeared in the Mining and
Scientific Press of March 10th last, the mill of the
Dakota M. & M. Co." at Central City, S. D., has been
in continuous operation, with the exception of hang-
ing up a day or two occasionally for some needed
repairs. The method of wet crushing in cyanide so-
lutions has been continued with such satisfactory re-
sults in economy of chemicals and percentage of sav-
ing of the greatest possible extractions that it would
not be changed, and is regarded by the management
as the best method of treating these ores. While
the practice has been the same as indicated in that
article, some changes in detail of operating have been
found to secure a larger tonnage increase. The
sands become too light to separate readily in the
agitator, and the "V" box was introduced. This
change proved of great advantage and made it pos-
oflBce rock-breaker, and then the fines screened out
through the twenty-mesh screen. The two samples
thus secured assay the same value. Samples of the
foam on the solutions flowing from the batteries have
at times been found of double the value of the ore,
and never been found of less value than the ore, the
solutions carrying the foam having a value of only
about one-fourth that of the ore. Precipitation sug-
gests itself as a possible explanation, which might
arise from the possible carbon in the ore shale, but
there is no evidence of loss. Another strange fact
is that the saving from the two products — the slimes
and the sands — vary but a few cents from each other,
and, one being known, the other can be closely pre-
dicted. The extraction from the slimes is better
than from the sands.
The best method of preparing mill solutions by
evaporation for assaying was recently made a matter
of experiment in the laboratory of this company.
Six samples were taken, each having a different gold
value, and ranging from moderately rich to very
poor, the latter representing the outflow from the
zinc box. These samples were treated in six differ-
ent ways. Ten assay tons were used in all, except
' the lead trays, in which two were used. All values
are reduced to single assay ton values. The first

sible to increase by one-half the amount of the ore
milled.
The ore pulp, coming from the batteries, passing a
six-mesh woven wire screen, is delivered by the
centrifugal pump to the "V" box, where a separa-
tion of the sands from the slimes is made by the prin-
ciple of that device. The slimes are run from the
"V" box to the agitator vat, where the slime
particles settle and the clear solution is siphoned off
and run to the sump ready to use again. The sands
are run from the "V" box into the percolating
vats, where, the drain cock being left open, the solu-
tion drains off and passes through the zinc box to the
sump to be used again. All this is continuous until
the sand vat is full, when the stamps are hung up
and the slimes are treated by agitation, first
cyanide being added to build up the stock solu-
tion, and then run to the slime vats, as de-
scribed in the former article. The treatment in the
slime vats is by means of a rubber hose connected
with a pump, and to the other end of which is a 5-
foot section of 1-inch gas pipe, by means of which the
slimes can be very well washed. The sands are
treated entirely with stock solution containing from
one to two and one-half pounds of cyanide per ton of
solution. It has been found, by many experiments of
continuous work for weeks at a time, that just as
good and quick an extraction can be made on the
Gunnison mine ore with a solution containing one
pound of free KCN as with a solution of greater
strength. This is of much importance, as great
economy in cyanide is thereby made possible. How
much weaker a solution can be used has not been de-
termined, as the present practice comes within the
limits of reasonable economy in chemicals. The total
consumption of KCN for the month of July was less
than one pound per ton for the ore treated. No at-
tention whatever is found necessary to the strength
of the solutions in KCN in the effect on the zinc pre-
cipitation, as the results are equally good with all
strengths.
It would be very interesting to know, the form and
combination of gold in this ore. Perhaps it will be
possible to determine this in the near future.
Samples taken for the purpose of determining the
value of the ore milled were run through the assay
assay of the first sample was run in duplicate and
allowed to burn black to see if accurate results could
be had in this way. The results were as follows :

Only such care was given as is practical in every
day laboratory work, and the differences in results
are just such as may be expected from following the
method. The assays which check probably repre-
sent the true value of the solution. The variation
from this check value, whether above or below, is
probably due to imperfect cleaning of the pans in
which the evaporations were made. The results
seem to show that results sufficiently satisfactory for
mill work can be had by any of these methods. In
evaporating in the pans without litharge, care must
be taken to finish on a square of asbestos paper, and
without burning. Evaporating in pans with litharge
at beginning gives the least trouble, and the use of
the pan has the additional advantage over the lead
tray that all errors are divided by ten, which quan-
tity is not practicable with the lead tray. The flux
used is the ordinary ore flux for a half assay ton, the
litharge being omitted in such as it has been used in
while evaporating. The pan is scoured — first being
slightly moistened — with half the flux, and emptied
upon the mixing cloth, and then a second scouring is
made with the remaining flux. It is then run in a
crucible, as any ordinary crucible assay. To deter-
mine how • well this method cleaned the pans, the
writer once took ten pans which had been poorly
cleaned and recleaned them with an acid wash and
assayed the washing, with the result of $11. As
these ten pans had had 100 assay tons evaporated in
them, the error amounted to an average of 11 cents,
but these had been very carelessly cleaned, and it is
not probable that the average error of the usual
practice is more than one-fourth that amount. Such
an approximate result is as accurate as the other
factors of mill work can be made, and the labor is the
minimum.
There is one feature in the mill practice of this
company which should commend itself. It is the
practice to hang up the stamps on Sunday. There is
no more apparent reason why a quartz mill should
run seven days in the week than a flour mill or a cot-
ton mill, and these latter close for Sunday. J. M.
Buckley, L. L. D., in the July Century Magazine
says: "The observance of one day in seven by a
complete change in subjects of thought, and the sus-
pension of modes of activity required for six days,
would be philosophical even though it had no basis in
religion. In the French revolution the attempt was
made to have a holiday once in five days, and again
once in ten. The intervals were too frequent under
the first plan, and did not occur often enough under
the second. The superintendent of one of the largest
hospitals for the insane declares that nineteen out of
twenty of the business and professional men who
come under his care have been in the habit of carry-
ing business on their minds for seven days of each
and every week." The men who are employed in
quartz mines and mills are certainly as much in need
of a weekly day of rest as any other class of men, and
the business will as well adjust itself to the necessary
arrangements and maintain a profit-making condi-
tion as any line of manufacturing.

Silver Smelting in Mexico.*
NUMBER VII.— CONCLUDED.
The bricked flue dust is an excellent material to
make a furnace run fast, and is especially useful in
smelting barrings and fine material like roasted tier-
ras and roasted matte. But in most cases it has to
be put on the ore charge to get it out of the way.
If much of this material is on the ore charge, the
weight of 1000 pounds can not be maintained, on ac-
count of its great bulk.
The work at the blast furnaces, steam engines and
boilers and at the calciners is performed in two
shifts of twelve hours each. All the other workmen,
mechanics and ordinary laborers, work ten hours, or
less if they are assigned a task (tarea).
There were employed on an average 612 men and
boys a day, whose wages aggregated $641.90. Of
this force, 32 were whites (Americans and Europeans),
2 American negroes and the balance of the Spanish-
American and Indian races. The white men occupy
all the prominent and responsible positions, as en-
gineers, head mechanics, assayers and foremen ; the
negroes are the head firemen at the boilers, and were
the only ones who could keep the steam up in the hot
season. The Mexicans of the Spanish- American race
fill the positions of under-foremen and mechanics; for
positions of trust they are unfit. The great bulk of
the workmen are Mexican Indians, who earn 37 cents
a day as water boys to $1.75 as picadores. Consid-
ering what they eat and where they sleep, they work
very well under proper supervision ; but they are un-
steady, and will leave en masse when the sugarcane
is ripe and they can get work at a plantation. They
are liable to stay away from work if a rain storm
sets in shortly before a change of shifts, or if a sud-
den spell of cold weather occurs, or when the fur-
naces are running too fast in hot weather. They are
apt to strike when they get a new foreman or even
superintendent, or when their mode or character of
work is to be changed. They even object to working
at a new furnace if tbey suspect that their work will
be increased thereby. These prejudices and super-
stitions will, however, gradually be overcome.
Twenty years ago it was an impossibility to get any
workmen at all in the " Semana Santa," that is, the
week before Easter ; at the present time it is pos-
sible to run furnaces during that period, although not
at full capacity.
Like all people of low education, they are addicted
to stealing in a small way if an opportunity offers,
and this propensity is fostered by the many buyers of
stolen goods who may be found in every Mexican
market place. Bullion thefts were a daily occurrence
for several years, until at last the Governor of the
State suppressed a small smelter at Sta. Catarina,
near Monterey, that subsisted entirely on stolen bul-
lion and ore. Such parasites are met with in almost
every mining camp of note.
The prevailing disease of the Mexican workmen is
malarial fever ; acute lead poisoning is rare, in spite
of the indigestible food they eat and their aversion to
ablutions; chronic lead poisoning is unknown. Acci-
dents are, however, frequent, owing to careless-
ness.
The arrangement of the repair shops, as carpen-
ter, machine, electrical, blacksmith and tinsmith
shops, is adequate to the requirements of the

smelter. The laboratory and assay offices are sus-
ceptible of improvement.
The various buildings composing the works are all
constructed of wood and galvanized corrugated iron,
painted on both sides with red iron paint or with
graphite paint. In spite of these precautions, the
iron is destroyed very rapidly by the action of the
atmosphere, which is especially annoying in the case
of the roofing. In California and Arizona a non-
met ullic roofing is now used extensively on industrial
buildings, which is known under the name of " P. &
B. ready roofing," and gives good satisfaction. The

The percentage of losses and gains is, of course,
variable, and is kept secret by everv smelter. I can
say this much : that in gold there is no loss — more
generally a gain — on account of the accumulation of
traces, which, as such, have no determinable value.
Some smelters also make a gain in silver, which is due
more to commercial than to technical skill.
Two more furnaces of larger dimensions than the
old ones were erected and housed in a building con-
structed of iron and steel throughout. Two 475 H. P.
triple-compound steam engines, two 150 H. P. marine
boilers, 9 feet in diameter, and a number of blowers
were added, and a third locomotive for hauling slag
was acquired. According to communications from
the designer of the furnaces, Paul Johnson, their sec-
tion at the tuyere level is 44 inches by 144 inches
wide. The water jackets forming the side walls
have a bosh, and are 18 inches wide by 4 feet high ;
they have a tuyere opening in the center, and there
are eight tuyeres in each side. The end jackets are
straight and have no tuyere openings. Owing to the
intense heat caused by the application of a blast of
a higher than the ordinary pressure (21 to 3 pounds
per square inch), it has been found expedient to in-
terpolate another tier of water jackets between the
deck plates and the regular jackets. The side walls
above the water jackets are also flaring towards the
charge door, to such a degree that the area of sec-
tion at top is twice the area of section at tuyeres.
This is done in order to diminish the.speed of the es-
caping gases and thereby the formation of flue dust.
The exact height from tuyeres to charge door I do
not remember ; some informants give it at 20 feet,
others at 25 feet. In the Raschette furnace the pro
portion of the area at the tuyeres to the area at the
charge door is as 1 : li, and the height of the smelt-
ing column is 16 feet 5 inches. Prom this comparison
it would appear that the principle of the Raschette
construction is receiving deserved recognition and is
being enlarged upon. It is claimed for these furnaces
that the production of flue dust is very slight, and
that the formation of wall accretions is greatly di-
minished. One of the new furnaces was put in blast
in April of this year, and the second soon after.
Their capacity was rated at 175 tons of charge in
twenty-four hours ; but, as is usually the case, no
such figure was ever reached, 136 tons being the
maximum of which I have heard. The cubic contents
and the pressure of the blast are not the only factors
which determine the capacity of a furnace. The in-
crease of the furnaces in height has brought about a
decrease in the consumption of fuel and the possibility
of making a more acid slag, and, hence, of smelting
more siliceous ore. The present consumption of coke,
per ton of charge (exclusive of slag), is 12, as against
14 to 16 in the 14-foot furnaces. The slag is com-
posed of : Si02 36, PeO 32 = 25 Pe, CaoO 18, not
determined 14 ; total, 100. It carries 11% of lead
and 11 ounces silver per ton, with bullion at 400
ounces.
The settling of the matte which flows from the
furnace with a large current of slag presents some
difficulties. The rectangular settler of the Orford
form does not seem to have given satisfaction and has
been replaced by a twin-pot settler. This is the old
Colorado Iron Works twin-pot, with this alteration,
that one bowl is elevated above the other sufficiently
to allow the slag to overflow from the higher into the
lower one through a spout. The elevated bowl is
placed directly under the slag spout of the furnace,
and catches the largest portion of the matte. The
slag from the lower bowl overflows by means of a
spout into an ordinary twin-pot, which is hauled
away to the edge of the dump by a locomotive. After
removing the twin-pots four times, the settling twin-
pot is also hauled out and replaced by a new one. At
a short distance from the furnaces the matte and
slag are poured from the settler into smaller pots,
and the shells are saved for resmelting. The waste
slag twin-pot is emptied as usual, but the shells are
dumped into a separate place for further treatment,
as they run just as high in lead and silver as the shells
from the small slag pots, in spite of the double set-
tling. This system of matte settling is rather com-
plicated and will be superseded, I understand, by
settling in a reverberatory furnace, as at the Arkan-
sas Valley Works, Leadville, Colo., and the El Paso
Smelting Works, Texas. This reverberatory furnace
is designated as a "separator." Prom latest ac-
counts I note that all the 42xl20-inch furnaces are to
be replaced by the 44xl44-inch size, and that the
blowers are being broken up to serve as desulphur-
izing flux on the charge.
The Small Gas Engine.*
It would seem one of those rigid, but withal, just
laws of nature that each new creation of man shall
have its own sphere of usefulness, squeezing up the
spheres of some of its older companions, modifying
those of others, but completely crowding out none.
Of the available powers for doing work, man, animal,
wind and water powers have gone along peacefully
for ages. Each has filled its place without puff or
bluster, and probably will do so for ages to come.
Of the more modern powers, steam, electricity and
gas, what a zealous, wiry lot they are ! Each would
make good his position in this world by a revolution
heralded by a million printer's ink trumpeters, but
as the rank and file contains only his own offspring
(decidedly immature in all cases) the initial skirmish-
ing is soon over with, the newcomer being com-
pressed into a very small but proper sphere to begin
his last but continuous campaign, during which he
will reach a position just so high or important as he is
capable of maintaining and no higher. This triangu-
lar competition has been on for some years, and it
may be of interest to examine somewhat the relative
status of the participants as indicated in the title of
this article.
The small gas engine may get its supply of energy
either from a gasoline tank or from the gas main,
while the electric motor has but one source, the elec-
tric main.
As to the cost of power from these three sources,
if we take into account only the actual horsepower
developed by each under fair to good conditions, put-
ting aside all other considerations, under the present
ruling rates for these forms of energy the gasoline
would come first, the gas engine second and electric-
ity last.
But power alone is not what is wanted by mankind,
but that power applied. A 1000 H. P. engine is
worth thousands of dollars to run a steamship, but is
not worth 2 cents to run a coffee mill. In other
words, power is of value only as it is applied, so that
it is the relative cost of the power as applied that we
must consider and not that of generation alone. Let
us consider, then, such properties of construction and
operation of the gas engine and electric motor as
would seemingly effect the ease of applying the power
which they generate.
Briefly, the working parts of small gas engines (and
large ones as well) are supported either in a horizon-
tal or vertical position on a comparatively heavy base
or bed plate. The principal part consists of the cyl-
inder, into which is drawn an explosive mixture of
gasoline vapor or gas and air, which mixture is then
compressed and ignited, creating a pressure which
acts upon the piston, driving it forward. The exter-
nal parts, with the exception of the admission, ex-
haust and ignition mechanisms, are so arranged as to
convert the reciprocating motion of this piston into
motion of rotation, the same as in the so-called trunk
steam engine. So far we are in a well beaten track.
It is only necessary to proportion these parts prop-
erly to have a well-behaved piece of machinery which
is easily understood and easily managed.
Not so, however, with the other parts mentioned.
It is probably safe to say that practically all failures
or difficulties with small gas engines arise from faulty
construction or lack of proper adjustments in the
parts controlling the three operations of admission,
exhaust and ignition.
It is not necessary at this point to explain the con-
struction nor to detail the possible ailments of these
parts to substantiate the statement that the mechan-
ism included by these three heads is not at all easily
*A. R. Curtis in the Engineer.
understood, especially as to the results of their action
upon the good or bad working of the engine.
But the fact that this mechanism is not readily un-
derstood is not of itself a serious feature at all. We
who are interested in mechanical affairs expect to
make such efforts as are necessary to gain at least a
working understanding of the machines that come
under our care, else how void of interest the great
mass of our work would be.
But the real question is: when once this mechanism
is understood, will it prove reliable? That is, when
put in adjustment by one thoroughly understanding
the engine, will it remain that way ?
The Corliss valve gear is far from an easily under-
stood piece of mechanism to one who has never
placed a moment's thought on it until he meets it as
part of a machine, which he must operate, but this
is counted as no objection to it, for it can be under-
stood, and, when once properly set and adjusted, is
exceedingly reliable.
Judged from the standpoint of any form of the steam
engine or the electric motor, these parts are not re-
liable in the sense mentioned, and there is nothing in
either the steam engine or the electric motor which
corresponds at all to them in this regard. It must
not be inferred from this fact that the modern small
gas engine is an unreliable motor, for it is not. But
this does mean that it must receive attention and be
accessible in a way that is not at all necessary with
small electric motors.
The other points that should be mentioned here are
as follows: In all makes of small gas engines there is
but one impulse, acting on the piston in one complete
revolution, and in the majority but one impulse in
two revolutions, which necessitates a very heavy fly-
wheel, and which results in a rather unsteady mo-
tion. Again, they are not readily started under load
or otherwise. They can not be reversed and if loaded
beyond their capacity will stop.
Unlike the gas engine, the electric motor is so well
known in its construction and operation that it will
only be necessary to point out the things that should
enter into this discussion.
There are three materials entering into the con-
struction of an electric motor, iron, copper and the
fibrous materials used for insulation. This insulation
is, in all forms, weak mechanically, but the enormous
amount of experience which has been accumulated
has made it possible to so introduce and protect this
comparatively frail material that there is no mechani-
cal weakness from this source. Motors will not
stand moisture, however, unless especially built to do
so. On the other hand, they give rotative motion
directly, with but one moving part, they will start
readily under any load up to full load and run with an
almost fixed speed, with no impulses of any kind.
They can be run in either direction and if properly
designed will, for short intervals, stand overloads
much in excess of their rated power. They can be
run in any position whatever and can be set up,
changed or removed in a very short space of time.
In all the good makes they are self-oiling and the
absence of exhaust valves of any kind is of great im-
portance in any small motor.
Where then is the place to put the small gas engine
with reference to the small motor ? Or, to put our
question in another form (since the small gas engine
is practically the newcomer), can the gas engine, in
general, place a part of its sphere within that of the
small electric motor ? Let us sum up.
Gasoline is universally obtainable, electricity only
partially so. This means there are thousands of
small shops where the small gasoline engine has the
entire field to itself. It is far superior to the small
steam engine for such places, and so long as current
is unavailable there can be no competition with elec-
tric motors. Absolutely constant speed is not at all
necessary in this field and there is no question but the
gas engine is here giving splendid satisfaction.
Next comes the same kind of a situation with the
addition that current is available. This would in-
clude all kinds of small shops and places where small
powers are used in cities and fair sized towns. Here
the .inflexibility of the gas engine as against the ex-
treme flexibility of the electric motor comes into
striking evidence.
Floor space is valuable. As a result the motor goes
up on the ceiling, wall or an odd post. On a large
job some distance from the shop it would save money
to have a power tool or two at the building. Down
comes the motor and in an hour is up again on the
other side of the city. It is started and stopped with
the machines, and if every advantage is taken of the
flexibility available small individual motors will be
placed on each machine, doing away with the use of
shafts, pulleys or belts external to the machine.
Here enters in the plainest possible way that ques-
tion of cost of power delivered at the machine. In
cases where a few machines are run intermittently,
but frequently, necessitating the running of a gas en-
gine continually, the motor can readily compete in
cost of power on account of the fact that the motor
under the same conditions can be stopped and
started as power is required.
The direct attachment to the machine of the power
to run it opens up an exclusive field for the small
electric motor, which, from all indications, is as free
from intrusion as that of the small gas engine where
current is not available.
In the intermediate field where both powers can be

used, circumstances and taste will influence very
largely which will be decided upon. If cost of run-
ning alone is considered the gas engine will be se-
lected. If extreme regularity as to speed, or relia-
bility without systematic inspection is required, the
electric motor should be selected.
Or again, if absolute independence of external
sources of power is required, together with relia-
bility, decide on a reliable make of gas engine, spend
a small amount of time to systematically inspect the
same, lay in a sufficient supply of gasoline and your in-
dependence will be complete and secure.
We conclude then that the small gas engine has
created a field of its own in which it seems quite se-
cure. Also that it has intruded and can intrude but
little upon the broad sphere now firmly established
by the small motor.
Keeping and Indexing Notes.
Written for the Mining and Scientific Press.
The keeping of notes is generally recognized among
engineers as of great value, and, though attempted
by many, is often given up, sometimes through the
lack of a little perseverance, but more often because
the system adopted does not meet the requirements.
The ideal system permits of keeping and classifying
notes in whatever form they are obtained — whether
as personal memoranda, clippings, sketches or pho-
tographs. They must be indexed according to sub-
ject ; must permit of easy reference ; should not be
too bulky ; all notes relating to one subject should be
together, and, finally, it should be possible to discard
obsolete matter, or matter that is no longer of use to
the engineer with his increased knowledge and ex-
perience.
Note books, with notes often accompanied by
sketches, furnish a fairly convenient form, but the
entries must be made consecutively, and not accord-
ing to subjects. This makes indexing rather dif-
ficult, and may scatter information on any given sub-
ject through half a dozen books, which greatly im-
pairs the usefulness of the system for reference pur-
poses. Moreover, no convenient provision can be
made for clippings, and they must either be copied
or provided for separately. The same applies to
photographs, which often serve to preserve a useful
idea or suggestion.
The following system has been tried by the writer
and has proved a success. It is simply an adaptation
of card catalogues, which have lately come so much
into vogue for similar purposes. The requisites are
a box of catalogue cards, such as are now made a
specialty of by many office supply houses; a note book
with detachable leaves, preferably ruled in the same
manner as cross-section paper, and a package of
large envelopes. Even better than the latter are
pieces of letter paper, cut to about Si inches square.
By folding these in the middle, there results a pack-
age ±i inches wide by Si inches long, which I find a
very convenient size. They are held together by a
rubber band.
The envelopes, or folded pieces of pa-
per, are now numbered on the outside
consecutively near the top, and on each
one is placed the heading under which its
contents come, with such sub-headings or
notes as may seem .necessary. For ex-
ample, we might have the following :
No. 1. — Mining, Costs. — Bullion mine,
Excelsior mine, stoping ; John Bull mine,
shaft sinking.
No. 2. — Power, Costs.

sition.
says of each individual metal. Also, to occasionally
look over the notes and to familiarize oneself with
them, will make reference to them easier and will in-
crease their usefulness.
With each entry I think it very advisable to give
its source. If a clipping, give the periodical from
which it is taken, with date or number of the issue.
If a personal memorandum, sketch or photograph,
state when and where made, and give the authority
for any statement included. It is then possible to
know what weight to attach to the notes when they
are made use of long after having been collected, and
when the precise circumstances of each case may
have been forgotten.
Short entries can oftentimes be advantageously
placed upon the cards themselves. If in the form of
short clippings, and folded papers are used instead of
envelopes, it is well to attach the clippings by means
of mucilage, otherwise they may easily be lost. With
long clippings there is little danger of this.
Pew, if any, men are interested in all branches of
mining, or of any of the other engineering profes-
sions, and it is generally better for a man to confine
the notes he collects to those relating to things in
which he is interested, and not to include notes on
subjects in which there is only a possibility that he
may be interested in the future. In this matter
every man must draw the line for himself.
The advantages of the system are manifest. It is
compact, yet provides for all kinds of notes, and of
various forms, and the information desired can be
easily found. The one source of information is the
box of cards, and it is found either on the cards them-
selves, or they refer to an envelope which can be
quickly picked out by number. Everything is in-
dexed according to subject, and all data on any one
subject are to be found in one place, and not scat-
tered. The system may be expanded to include an
index of magazine articles, by subject and titles only,
but this is of doubtful value. What is wanted is in-
formation that is available on the spot, and a list of
magazine articles is seldom of use unless a library is
within reach. If a library is near at hand, it is easy,
when the occasion arises, to look over the files of the
magazine, a task that is much facilitated by the in-
dex that most magazines print at the end of each
volume. An index of books is of greater value, and
less bulky. Wherever a man is, he can almost always
send for a book. The cards should be arranged ac-
cording to subject, and, if possible, should give
author, title, name of publishers, size, edition, date
of edition and date of entry, pages and price. It is
true that many publishing houses issue lists of books,
both of their own publications and that of other
houses ; but the lists are seldom all inclusive, and if
a man sees or hears of a book that he is likely to
want, it is better to make a note of it at once.

for their machinery for mines on this coast, and have
a demand for foreign trade, shipping to Mexico,
British Columbia, Alaska, Australia and to some

Electricity in Various Things.
During a recent discussion at a meeting of engineers
■where boiler explosions were under discussion, the
point was brought out that electrolytic action played
some part in boiler explosions. One of those present
gave his experience as follows:
" I had a novel experience in the gas plant of the
San Jose Light & Power Co., which is not near the
electric light works, and there are no lines which
could bring in any electricity. Holding my hand
near a leather belt a flame would come out near the
knuckle. Go under a belt and you can feel your hair
raised by frictional electricity. If you go on top of a
boiler and put your knuckles near the drum you will
see a blue flame. Your hand could not actually come
into contact with the boiler because it was hot."
Another added: "There is no question but that
static electricity may exist in anything under certain
circumstances." While another said: " I have noticed
practically the same thing under different circum-
stances. You cannot touch any of the wires of a
transmission line in a great rain. In repairing you
have to work with rubber gloves even when no ma-
chines are running."
"It is a well known fact," said a listener, "and
probably familiar to all of you, that in those meteoro-
logical tests where experiments are made by flying
-Dynamite. — Handling ; compo-
Notes on the different subjects are
slipped into the corresponding envelopes,
entries are made on the cards as follows :
Mining (to be written on the top line in
the middle of the card), and Costs (on the
same line, but near the right hand edge),
and then below. Notes on the cost of
mining. See No. 1. And in the same way
with the other subjects.
Since it very often happens that the
cost of power depends on the amount of
fuel used, the information might be sought
for under the heading "Fuels." It is
therefore best to put this heading on a
card, and under it to write : Fuels, con-
sumption of, etc. See under Power,
Costs, No. 2.
For the same reason, one card is headed
"Dynamite" and another "Powder,"
but both will refer to the same envelope.
As a rule, one heading will suffice, and it
is seldom that more than two will be neces-
sary. It is true that one objection to be
urged against this system is that there
will sometimes arise a doubt as to what
heading an entry should be classified
under, but the above method of double indexing
will in a large measure remedy this trouble, and to
this may be added the suggestion that it is usually
better to classify under headings with a broad scope
than to go too much into detail. For example, it is
better to have one envelope for "Assays," rather
than to use a separate envelope for notes on the as-

Arguments in the case of the Cosmos
Exploration Co. vs. the Gray Eagle Oil
Co. was made in the Circuit Court at Los
Angeles this week before Judge Ross.
The case at bar involves the issues exist-
ing between the mineral locators and the
scrippers. Both sides are confident ; the
Judge's decision will be regarded as a
precedent. The present suit is an action
for the appointment of a receiver, and it
is supposed will be followed by others,
whenever any scrip selections have been
made in tho Kern district.
Echo : Oil shipments from the Kern
River district have reached about twenty
carloads a day. Last Sunday a train of
twenty-eight cars was pulled out of the
field. This would show a daily produc-
tion of over 3000 barrels. The prediction
is now being made that within five months
a daily production of at least 10,000 barrels
will be reached in the Kern river fields
alone. Twenty carloads of oil were pur-
chased last Saturday by the Southern
Pacific. The sale was made by the Kern
River Oil Co., operating in the McKittrick
field.
MARIPOSA COUNTY.
(Special Correspondence). — Capt. A. H.
Ward has at last made satisfactory ar-
rangements regarding the Hite mine. The
old mine has yielded over $2,750,000 in
gold, and, by the payment of $46,000 to
Hite, the Hite Cove G. M. Co. takes pos-
session. The 1100 shaft will he sunk 200
feet deeper, the ore chute will he drifted
on and new appliances put in. The Miners'
Loan & Investment Co. of Boston, Mass.,
is in the deal, and Capt. H. H. Todd of
Alameda will probably have his head-
quarters, as manager, at the mine here,
while the San Francisco office of the com-
pany will be at Capt. A. H. Ward's busi-
ness office, 71 Stevenson St. All the par-
ties mentioned have interests in the new
organization, and work will now begin on

PLACER COUNTY.
The Sacramento folio of the U. S. Geolog-
ical Atlas says : During the Neocene period
the auriferous gravels accumulated on the
slope of the Sierra Nevada, and at the
same time there was deposited in the gulf
then occupying the great valley a sedi-
mentary series consisting of clays and
sands to which the name "lone forma-
tion " has been given. Beds of this age,
which probably underlie the larger part
of the Pleistocene or surface formations in
tho valley, are exposed only to a limited
extent. At Lincoln there is a succession
of whitosand and clay bods containinga few
seams of lignite. North of Rocklfn the
same series 50 to 100 feet thick is exposed
in places below andesitlc beds. Tho
strata form characteristic flat-topped hills
and consist of light colored clays and
white or yellowish-brown sandstones. On
top of tho lone formation there is usually
a layer of reddish Pleistocene gravel a few
feet thick. The highest point at which
tho beds are found is about 450 feet abovo
sea level.

YUBA COUNTY.
The Marysville & Nevada Power &
Water Co. proposes to build a ditch and
flume from the Feather. Chief Engineer
Engelbright's report gives figures for the
construction from a point at the dam to a
point 19 miles below: Ditch proper, 8 feet
on bottom, 13 feet top and 5 feet deep,
grade 7 feet to the mile, 15 miles, esti-
mated cost $20 per rod ; 4 miles flume, 8
feet wide, 5 feet deep. At upper or re-
ceiving end flume 9 feet wide, grade 9 feet
to the mile, estimated cost $35 per rod.
At a point 19 miles below the dam it is
proposed to discharge 2000 inches of
water under a pressure of 400 feet, to fur-
nish 1800 H. P. From the above point it is
proposed to construct a ditch and flume
6 miles that will carry 8000 inches of
water: required dimensions of. ditch :
Bottom width 7 feet, top width 12 feet,
depth 5 feet, grade 8 feet per mile ; flume
7 feet wide, 5 feet deep, grade 10 feet to
the mile ; 3 miles of ditch, estimated cost
$18 per rod ; 3 miles of flume, cost $28 per
rod. It is considered practicable to dis-
charge 4000 inches of water into the Yuba
river at this point under a pressure of
1200 feet, furnishing 1200 H. P. From
this point the water must be carried
through the divide separating North
Yuba from Dry creek by a tunnel.

shaft is down 374 feet. The streak varies
from 6J, to 29 inches in width. The pres-
ent contract will finish the shaft to a
depth of 500 feet, and no drifting will be
done till the 500-foot mark is reached.
Stations will be at 200 feet and 500 feet.
The mineral will average $14 per ton, al-
though assays have ranged as high as
$165 per ton.
FREMONT COUNTY.
The Rocky Mountain smelter at Flor-
ence will be ready for operation Nov. 1.
It is an independent concern, is backed
principally by Iowa people, and when com-
pleted will have a capacity of 550 tons of
ore a day. It is to be a semi-pyritic smelter,
drawing largely upon Cripple Creek dis-
trict for silicious ores.
GILPIN COUNTY.
Register-Call : At the Running lode,
near Black Hawk, drifting is carried
on in the seventh or bottom level at
a depth of 530 feet on both sides of
the shaft. The west level shows a
streak of rosin zinc and lead ore about 12
inches wide, which carries values of $109
per ton. Stoping is being carried on in
the sixth level, where milling ore is being
taken out, found in crosscutting by Supt.
Dunstone. Two shifts are at work, twenty-
four men ; seventeen are day's pay men,
the rest leasers. Enough ore is being
shipped to keep three batteries going at
the local stamp mills. It is being operated
by the Gowers Mines Syndicate.
A shipment of smelting ore made at
Black Hawk from the Freedom mine on
Winnebago hill gave returns of 3.36 ounces
gold and 4.40 ounces silver per ton for a
lot of 11,840 pounds, and for another lot of
3400 yjounds returns of 2.52 ounces gold
and 2.50 ounces silver per ton were ob-
tained.

Manager McMillan of the Sierra Blanca
M. & R. Co., operating on the eastern slope
of Sierra Blanca, has three tunnels started.
He says his company contemplates the
erection of a mill at the foot of the moun-
tain and connected by a 1500-foot tramway
with the mouth of the tunnel.
The work of broad-gauging the entire
system of the Colorado & Southern Rail-
way to Leadville has begun. When com-
pleted, all of the mines of the silver-lead
belt will be reached by a broad-gauge line,
which will do away with the necessity of
hauling any ore after one loading. Under
the present system it was necessary to re-
load the ore from the mineral belt narrow-
gauge line to the broad-gauge cars.
Miner: At Leadville the Home M. Co.
is sinking the Penrose shaft. The siliceous
ores of the Penrose carry about 50 ounces
in silver and 14% lead. The iron ores
carry 12% to 18% in lead and paying values
in gold and silver.
OURAY COUNTY.
The Ouray Herald says the Camp Bird
property has not been sold. "The man-
agement does not seem cognizant of any
unusual transaction and great prepara-
tions are being made for fall and winter
work. The output will be doubled and
500 men will be working by Nov. 1."
SAGUACHE COUNTY.
Near Crestone the San Luis Valley L. &
M. Co. have the machinery for their 100-
stamp mill on the ground. The company
has a 5-inch streak of hematite, carrying
twenty-eight ounces gold and five ounces
silver.
Four miles north of Crestone the San
Isabel M. & M. Co. have a fifty-ton con-
centrator completed. Manager Granville
expects to have it in operation by the 10th
inst. He is building a tramway three-
fourths of a mile in length to convey the
ore from the mine to the mill and putting
in a six-drill air compressor.
Bonanza reports the sale of the Eagle
mine to Creede men for $60,000; cash,

SAN MIGUEL COUNTY.
(Special Correspondence). — The Tom
Boy mill in Savage basin is treating 180
to 200 tons of ore per twenty-four hours.
This is quite distinctively a free milling
proposition, as doubtless 85% of the saving
is made on the amalgamating plates upon
which the material, thirty mesh, dis-
charges from the seven Huntington mills.
The other 15% saving is made in the con-
centrates from Frue vanners, the product
of the latter being unusually clean, per-
haps carrying only from 5% to 7% of
silica. The entire mill has been operated
by electx-ic power during the past year,
same being transmitted from the plant of
the Telluride Power & Transmission Co. at
Ames. The seven mills are run by two
motors of 50 H. P. each ; the crushers and
rolls by a motor of 50 H. P. ; a 100 H. P.
motor operates the six-drill compressor ;
at a point in the main tunnel, about 3000
feet from the entrance, a 100 H P. motor
operates a hoister at the three-compart-
ment shaft which extends from the 600-foot
to the 800-foot level. Adjoining the motor
room at the mill is a transforming station,
by which the 10,000 volts from the main
power house are transformed down to 110
volts for motor use. Rawhide pinions are
to be brought into use on the gearing of
the electric hoist to partially do away
with the deafening noise produced by the
metal gearing. The main tunnel and the
principal drifts on the different levels are
well lighted by electricity.
The Tom Boy Co. has a bond and lease
on the Argentine property, which covers
a well-defined lode almost parallel to that
of the Tom Boy and extending through
the range from Savage to Ingram basin.
The outcropping of the Argentine is very
conspicuous and the lessees, in driving a
drift on the ledge from a point just below
the Tom Boy mill, have run into ore of
good values, and which thus far appears
to be a sulphide of lead and iron. Further
developments on the Argentine are likely
to be important.
The Columbia lode lies farther south-
ward and runs nearly parallel to that of
the Argentine. The former was a pro-
ducer a few years ago, but has been
closed down during the past two years.
Recently a reorganization was effected
and the mine and mill were started up a
few weeks ago under the name of the
Menona M. & M. Co., with R. W. Davis,
Jr., as Supt. The mill is operating ten
stamps and five concentrators, from thirty
to thirty-five tons of ore being put through
daily. No plates are used, The concen-
trates run well in silver, lead and gold,
making a product worth about $65 per
ton. Present efforts are directed to clean-
ing out the drifts and levels and retimber-
ing. The mine is opened through two
tunnels — the upper going in 350 feet on
the vein and the lower tunnel cutting
1361 feet as a crosscut to the vein. On
the level of the lowel tunnel about 1500
feet of drifting has been done, which, it is
claimed, shows the vein to range from i
to 15 feet between the walls. The owner-
ship of the Columbia, now the Menona, is
in the hands of Eastern people.
The Japan concentrating mill is running
very successfully and has some interesting
features. The material, after passing
through crushers and coarse rolls, is
carried to a three-mesh screen, the over-
size from the latter being returned to the
rolls ; but that which passes this screen
goes to a four-mesh screen, the over-
size from the latter passing to the coarse
jigs. What passes the four-mesh is car-
ried to an eighteen-mesh screen, the over-
size from the latter going to the second
jig. The material that goes through the
last named screen is carried to a hydraulic
separator, the heavy product therefrom
passing to the fine jigs. The overflow
from the hydraulic separator is converged
to the slime jig. The tailings from all
the jigs pass through a 5-foot mill, having
one-millimeter screens. Then the prod-
uct of the mill is carried to hydraulic
sizers, the coarse from the latter going
over a Wilfley table set to run 245 revolu-
tions per minute. The heaviest material
from the hydraulic sizer is drawn off to a
second Wilfley table which runs 265 revo-
lutions per minute. The overflow from
the second hydraulic sizer passes to a
Triumph vanner. The systematic, care-
ful work in the Japan mill is due largely
to the efforts of Supt. M. B. Pickel, who
has had extensive milling experience in
Montana, as well as in Colorado.
The Liberty Bell mill is steadily operat-
ing with batteries of forty rapid-drop
stamps, crushing 120 to 160 tons of ore per
day. To increase the amalgamating sur-
face double-decked plates are in use. The
material from the plates is carried by
hydraulic distributors to double-decked
Wilfley concentrators. The tailings from
the tables are subjected to cyanide treat-
ment and this constitutes one of the most
interesting features of the mill, being a
demonstration of the South African direct
method. By means of Butters distribu-
tors the tailings pass from the tables to
300-ton circular vats, each 30 feet diameter
and 8 feet deep, built of California red-
wood. The Butters distributor, one to
each vat, is made to revolve by the force
of the discharge, thus distributing the
material to every part of the vat, the
heavier particles constantly settling and
the slimes, held in suspension in the water,
overflowing at the six slime gates on the
sides of the vat. By this means the flour-
fine clays which would retard percolation
are to a large degree drawn off, the dis-
tributors keeping the slime-laden water in
a state of agitation during the process of
filling the vats from the concentrator tail-
ings. When the vats are filled with these
settlings the moisture contained therein is
drawn off by vacuum pumps. Then a
weak solution of cyanide is applied and
after a short-time treatment the entire
mass from each vat is discharged through
bottom gates into a vat of same dimen-
sions immediately under it, where a
stronger cyanide solution is applied ; and
after the leaching is complete the solution
is drawn off into the zinc precipitating
boxes in the usual way. After precipi-
tating the solution is drawn into a sump
tank where its cyanide strength is tested,
thence it is taken to the regular solution
tanks, where sufficient cyanide is added to
bring the whole up to the requisite
strength. About nine days are required
from the time the material is distributed
into upper vats till the refuse is drawn off
from the lower vats. The management is
now starting to treat 4000 tons of tailings
collected last season. Forty additional
stamps have been ordered and likewise
additional vats and tanks. There are
now three upper and three lower vats in
use. When the mill capacity shall be
doubled there will be five upper and five
lower vats in use. The work of the mill
is automatic and it is claimed the tailings
have about equal value in gold and silver,
and that the cost of treating them falls
below 75 cents per ton. The main values,
of course, are saved on the plates, though
the close saving in concentrates and the
tailings therefrom constitute a most in-
teresting feature. The cyanide feature
was designed by F. L. Bosq ui, formerly at
the Standard mine and mill at Bodie, Cal.
J. W. Mercer is manager of the Liberty
Bell mine and mill.
The new Smuggler-Union mill has been
running since about the first of the pres-
ent year. A quite complete description
of its construction appeared in this paper
in November, 1899, and an illustrated ac-
count of its workings was published in the
Mining and Scientific Press in the
early part of this year. It is now observed
that practically no changes from the orig-
inal plans and equipment have been found
necessary. The eighty rapid - drop, 1000-
pound stamps, twenty-four Gilpin county
bump tables below the plates, four Chilian
mills and four Wilfley tables set upon
intermediate platforms between the amal-
gamating floor and vanner floor ; the
thirty-six Triumph vanners on the lower
floor constitute the essential features of the
equipment, with the exception of the power
department. In the result about 40% of
the saving is on the plates, 60% in the va-
rious concentrate products. The concen-
trate product runs high in silver ; the
bullion retorted from the amalgam runs
only a'bout $10 per ounce. The bumping
tables perform an important part. By
them three separations are made. The
material in passing from the plates to the
bumpers falls upon 18-mesh screens ; that
which fails to pass the latter is carried to
Wilfley tables and Chilian mills. That
which does pass the 18-mesh screen to the
bumpers is separated into two classes — the
first being the heavy concentrate which is
saved off the bumpers, the second being
the tailings which pass from the bumpers
through laterals down to the Triumph
vanners. The material in discharging
from the Chilian mills comes in contact
with amalgam plates before passing to the
vanners below. A tank on the interme-
diate floor is supplied with hot water from
the condensing engine for vanner use.
The new mill is operated by steam, but
a large electric generator iB being put in
at the mill to be operated by water power,
for which a pipe line is being run to con-
vey water from Bridal Veil basin. The
new generator will operate a 30-inch double
cylinder air compressor already in place
at the mill. This compressor will operate
drills in the Smuggler-Union's Pennsyl-
vania tunnel through a 3500-foot pipe line
now being put in. Incidentally it may be
noted that a connection is being made be-
tween this company's Bullion tunnel and
Pennsylvania tunnel, a vertical distance
of 750 feet. A winze from the former and
an upraise from the latter are in progress.
The two Smuggler-Union mills are hand-
ling between 12,000 and 13,000 tons of ore
per month, and the gross output there-
from per month amounts to a little over
$80,000, or at the rate of nearly $1,000,000
per year.
Among the properties in Gray's basin,
between Ingram and Bridal Veil, is the
Mayflower, operated by E. L. Davis and
associates. The property has about 1000
feet of development, is working two shifts
per twenty-four hours and taking out
quite a tonnage of ore, which is carried by
pack animals to the Smuggler-Union mill
for treatment.
The Keystone placers near Vance Junc-
tion are being worked with a Ludlum ele-
vator, by which the bedrock was reached
a short time ago at 60 feet depth.
The Special Sessions, on Mt. Wilson, be-
longing to E. L. Davis and others, is a
gold property at about 12,000 feet altitude,
and is 9 miles from Rio Grande Southern
railway at Wilson. The property is being
developed, but is not shipping as yet. An
upper tunnel goes in 300 feet on the ledge ;
a lower, crosscut tunnel cuts the vein 150
feet from entrance, there being drifts on
the vein 250 feet each way from crosscut.
From this level an upraise goes to the sur-
face. A second crosscut extends from the
Sessions to the Oasis vein, a distance of
200 feet. A 45-foot shaft has been sunk
from lower level of Sessions, all in ore. It
is claimed 6000 tons of ore are in sight,
that the vein carries a pay streak about 1
foot wide, carrying values running $35 per
ton. Some of the gold herein is free, but
in the main it is a concentrating proposi-
tion. Mr. Davis thinks a mill may be
built.
The Gold Run Extraction Co. of St.
Louis, under the management of F. L.
Bosqui, is operating a cyanide plant near
Pandora, extracting the gold and silver
from the placer tailings which have accu-
mulated in banks and bars along Marshall
creek during the last twelve or fifteen
years. The deposits, in the main, consist
of tailings from the Smuggler-Union,
Tom Boy, Japan and other mills in Mai'-
shall and Savage basins. The plant was
built last fall, but since Mr. Bosqui took
charge, two months ago, it has been en-
larged from 100 to 200 tons capacity per
day. It consists of two storage solution
tanks, 22x64 feet; two gold solution tanks,
22x44, feet ; two sump tanks, 22x64 feet ;
twelve leaching tanks, 25x54 feet, of
100 tons capacity each. The leaching
tanks are ranged in two rows, with a
graded bridge, 18 feet wide, extending over
each row of tanks, the bridge surface be-
ing of 2x4-inch scantling set on edge, 2
inches apart, permitting the tailings,
which are hauled and dumped from wag-
ons, to fall through into the tanks below.
Each tank, after the leaching, is sluiced
out through a center disk gate at the bot-
tom. The company has a two years' lease
on the tailings from the two Smuggler-
Union mills. Within ten days the plant,

SILVER BOW COUNTY.
Near Butte work on the Smokehouse
lode Is resumed. The noise new electric
hoist is operated, not to be subdued, as it
is operated wholly by gearing, no leather
belts being used. The new hoist is of 75
H. P. and has a sinking capacity of 700
feet. There was so little room to work
that the company bought the lot on which
the hoist stands, paying for it $22,000.
The company owns fifty-two acres of
ground in the heart of the city. The lot
just bought will be used to cut the timbers
on. The timber to be used will be 10-inch,
as electricity will be used for blasting in
the mine, and blasts caused by electricity
will shake the smelter timbers out of posi-
tion. The company intends to sink a
shaft of three compartments on the De-
stroying Angel lode, one of their proper-
ties, 1000 feet deep.

(Special Correspondence). — Recent for-
est fires have delayed progress as most of
the companies have been compelled to use
their men to fight fires, which have done
considerable damage. After the State
officials withdrew their men and when the
fire was only 1 mile from here we fought
the fire and yvhipped it out. We had a
fire line 4 miles long, and after three
nights and four days succeeded. At first
the people shouted it would be useless, as
it would take more men to whip the fire
than to whip China. Had this fire got in
it would have been death to this camp, as
all the timber for miles around is de-
stroyed. The Ferris-Haggerty lost 1000
cords of wood alone, beside other damage,
and the fire is still burning around Battle
lake. The Ferris-Haggerty is about 6
miles from there. Mr. Ferris' death has
put a stop to the Manhattan deal which
was pending. Sweet & Cling have located
several iron claims within 6 miles of this
mine and have found gold float 3 miles from
here. The smelter is an assured fact.
The contract has been let for the ma-
chinery. Before the contract could be let
it was necessary for Chas. E. Knapp, man-
ager of the Boston & Wyoming Smelter
Co., to raise $100,000 cash. This he has
done and the contract for the hauling of
146 tons of machinery from the railroad
to Encampment has been let. Dr. Bur-
ger, manager Great Lakes mines, has his
shaft house completed. The K. C. mine
is about 5 miles from Encampment. The
Great Lakes mine is taking out good cop-
per ore. The fire near the Great Lakes
mine was so fierce that the flames shot 100
feet in the air above the tree tops, but no
damage was done to the G. L. M. shaft
house.
Encampment, Aug. 31.
FREMONT COUNTY.
At South Pass the Carrisa mine has
been incorporated under the name of the
Federal G. M. Co. The lower level has

covered that carry ore.
FOREIGN.
AUSTRALIA.
In mining the rapid increase in the pro-
duction of gold in 1897, 1898 and 1899 has
so far this year been checked, and it is
probable that the total will not much ex-
ceed that for 1899— say about 4,000,000 fine
ounces. The expectations formerly held
with l'egard to some of the Western Aus-
tralian mines have hardly been realized.
On the other hand, there is always the
possibility of fresh discoveries to be kept
in mind. The high prices of the industrial
metals have proved of great advantage to
the Broken Hill lead mining field, as noted
on the editorial page, and the Tasmanian
copper field. In several parts of Australia
considerable development of copper prop-
erties is in progress, and there is no doubt

kinds that still remain to be made com-
mercially profitable.

place big orders for ordnance there. When
everything is ready the Czar will occupy
Manchuria and fight Japan. Russia does
not anticipate any interference from the
other powers in her Manchurian move."

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co.'s Scien-
tific Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Machine for Spreading, Truing
and Gaging Drills.— No. 656,415. Aug.
21, 1900. David G. Morgan, Quartz Moun-
tain, Cal., one-half assigned to R. H. Mc-
Namara, same place. This invention is
designed to spread, true and gage rock
drills of that class in- which the cutting
bits are formed at right angles with each
other. It consists of tools or formers, the
first of which has separable channeled
jaws, means for holding the drill in con-
tact with the jaws and operating them so
as to spread the bits, a die follows by
which the ends of the bits are squared or
straightened after being spread, and
finally a gage or sizer into which the bits
are successively inserted to bring them to
the proper size. The hammers which act
to produce these various operations are
preferably actuated by fluid pressure.
The device is rapid and economical, as it
makes it possible to do the whole work at
a single heat.
Process of Leaching Ores or Tail-
ings—No. 656,395. Aug. 21, 1900. Ed-
ward H. Dickie, Bodie, Cal., one-third as-
signed to James Kane, same place. This
invention relates to improvements in the
leaching of ores, tailings and like material
containing valuable precious metal in con-
junction with a cyanide solution, and is
especially designed for use in connection
with such ores or tailings as contain base
substances which act upon the cyanide in
the solution and render it unfit to dissolve
the precious metals. This solution pre-
vents the base substances from uniting
with the cyanide to destroy its power of
dissolving gold and silver. The result ia
obtained by adding to the cyanide solution
a substance which will unite with the base
metal forming a salt thereof, and which
has little or. no affinity for the precious
metals, thus allowing the solution to act
directly upon the precious metals. The
ores are leached in the usual manner.
Catalogues Received.
"Electric Power" is an edition de
luxe of a volume portraying Westing-
house electric motors applied to stationary
service. It is intended for distribution at
the Paris Exposition, and is printed in
French, English, German and Spanish.
It is a handsome specimen of typographi-
cal excellence, showing the electric motor
operating machinery of every kind all
over the world. There is no "talk," or
description, merely pictures and an ex-
planatory title to each. The pictures are
works of art. The one on page 129 is about
as finely executed a half tone as any
seen.
Obituary.
Near Glendale, Or., on the 3rd inst.,
E. W. Dana, a mining superintendent, was
killed at a shaft on the Copper Stain mine,
of which he was in charge. A whim was
being worked by a horse, when the har-
ness broke, allowing the bucket to start
down at great speed, and Dana, in his ef-
fort to stop it, was struck by a harness
hame over the heart, killing him in-
stantly.

The New York Report says the recent
advance in the price of pig lead by the
A. S. & R. Co. is said to be coin-
cident with an agreement entered into
by them with the principal Western min-
ers of lead ore. In accordance with
this agreement the A. S. & R. Co.
are reported to have agreed to pay
the lead ore producers a flat rate based
upon a price of 4 cents per pound, New
York, and to maintain this rate for the
balance of the year 1900. Heretofore the
price paid by the smelting company has
been based on what is known as the
brokers' or bullion price which was
fixed by the most recent sale of fifty
tons of lead delivered New York. The
bullion price was usually from $2 to $5
September 8, 1900.

SPADONE'S CONCENTRATOR BELTS.
PATENTED.
This illustration shows the edge flanging out-
wardly as it passes over the pulley. This re-
lieves the strain from the top and bottom of the
edge by directing the strain automatically to
the inside face surface of the edges. Hereto-
fore all belts have been so constructed that
when they pass over the pulleys or rolls, a di-
rect strain comes upon the top or at the base of
of the edges, causing the edges to break away
from the body of the belts in a very short time.
We avoid this Mechanical Defect by our Spadone
Curved Edge. Belts made to fit any machine—
4, 5 and 6 feet wide. Prices and samples on ap-
plication.
AMALGAM PLATE CLEANERS.
Our Amalgam Plate Cleaners are made of Pure Rubber in moulds, thus insuring a plate cleaner
which will not scratch the plates and a perfeot edge which will clean the Amalgam plates evenly.
They are made 6 inches long, 3 inches wide and H inch thick, making a convenient size to handle.
Price by mall to any address, each 75 cents. Correspondence solicited.

CROWN GOLD MILLING CO
Manufacturers of the "CROWN" CONCENTRATOR and CROWN
ORE 5IZER. A dry process of sizing and concentrating ore, sand or
gravel. Designed to accord fully with the laws of specific gravity,
and especially adapted to refractory ore or localities where there is
no water.
The chief claims for the Crown Concentrator are that it occupies
less floor space and has nearly four times the capacity of any wet
concentrator; that it will concentrate ores containing base and refrac-
tory metals that ordinarily slime and carry off values; that it effects
a saving of values far above the ordinary methods of concentration.

We have, now in operation, a complete plant
for crushing, sizing and concentrating ores by the
Crown Dry Milling Process.
Mine owners desiring tests made can forward
us, freight prepaid, not less than 1000 lbs. nor
more than 4000 lbs. of sample, for which a
charge of $20 will be made. (This amount in-
cludes assaying, etc.)
Ores for which this process is adapted and of
which consignments are solicited are any con-
centratable ores, pulps, tailings, or sands, carry-
ing sufficient values, whether they have hereto-
fore been profitably concentrated or not.

The result of ten years' solid work. Success at last. What
we wanted, and the public demanded, was a Gates Gyratory Rock
and Ore Breaker (always adjustable and indestructible) so modified
in design as to make one-half-inch product from three-inch sizes,
rapidly and cheaply. The H. Fine Crusher will do this work. It
takes the place of expensive big rolls and often prepares ore,
without further crushing, fine enough for coarse concentration or
cyaniding. In any event, it is the greatest and best intermediate
machine between the coarse breaker and the pulverizer.

The above illustration shows the
method of holding and sighting BRUN-
TON'S PAT. POCKET MINE TRANSIT,
when taking courseB or horizontal
angles. The construction is such as to
permit of simultaneous sighting and
reading. No tripod or Jacob's" staff is
necessary, and an operator, after be-
coming accustomed to its UBes, can
take the Transit from his pocket, take
a reading and replace the instrument
before a sighting compaBB can be
placed. The most accurate and rell-
bale pocket instrument on the market.

GRIFFIN
THREE ROLLER
7VYI
The GiilTin Three Roller Ore Mill is a simp.y constructed Mill, suitable for working all kinds of ores that
require uniformly fine crushing by the wet process. This Mill is a modification of the well-known Chilian
Mill, but the rollers run upon a crushing ring or die, which is inclined inwardly at an angle of about 30 degrees,
the rollers themsolvcs also being inclined to the central shaft of the Mill, thus utilizing the centrifugal force,
as well as the weight of the rollers themselves as a crushing agent. The Griffin Three Roller Ore Mill is there-
fore a Mill of groat strength, and has few wearing parts. We construct these Mills with extreme care, using
§9* only the best of raw materials, which aro most carefully worked by men who are specialists as mill builders.
fl We sell the Griffin Ore Mill on its determined merits, and will gladly supply full information regarding it to
B?>' any one.

THE LITTLE ALASKA GOLD WASHER.
After several yearB' practical
use in different fields, our
washer has established Its
superiority over all placer or
beach washers. It is just the
waBher for CapeNome; itwas
used extensively in Alaska
last year with every Buccesa.
In working the operator does
not have to wet his hands and
can stand in an upright
natural position. It Is
just the washer for the
poor man who has not
the money to put in ex-
pensive machinery. It
will do the work of ten
men with gold pans. It
is just the washer for
the prospector, being
light and easy to pack.
Don't fail to write us if in need of a washer; we
can save you time, labor and money. RUSSELL &

THE BROWNELL "PATENT LIP" FLANGE FRUE VANNER BELTS.
It has taken years of ceaseless testing and experimenting to produce the superior belt which
we now offer, with elastic flanges and pliable body reinforced with specially woven duck. Every
belt is manufactured by experienced workmen, and carefully tested on machines especially built
for that purpose; consequently we are to-day manufacturing the best belts that mechanical in-
genuity, combined with honesty of construction, can possibly produce.

MR. J. S. BROWNELL — Dear Sir: I take pleasure in saying that I have used your Patent Lipped flange belt for several years while con
nected with this company, and I consider them the best that we have used. The quality of rubber in the flange seems to be the best, and we are not
bothered with the flange cracking and thereby destroying the life of the belt. At present we are using 14 concentrators, and have in use several
kinds of belts. We consider your Patent Lipped flange the best. Yours very truly, THE CONS. SOUTH SPRING HILL G. M. CO.

Campagnie du Boleo.
At Santa Rosalia, Lower California, are the head-
quarters of the Compagnie du Boleo, a large mining
and metallurgical concern, that has spent several
million dollars, employs thousands of workmen, and
produces large quantities of copper matte. It is dis-
tinctively a European enterprise, owned and oper-
ated by Frenchmen, and nearly all its transactions
are carried on with Prance and England, though,
of course, the mining, smelting, and electrical machin-
ery is of American construction. The company was
organized in 1885; its operations are carried on in a
paternal sort of way, suited to the environments ;
good wages are paid, the most modern appliances
are in use, and the three groups of mines — the Sole-
dad, Providencia and Purgatorio— constitute an un-
usually large and extensive body of copper ore.
The accompanying illustration graphically portrays
the surface conditions. In the smelting works there
are twelve furnaces, with a daily capacity of 1000
tons ; the railway is 35 kilometers in length, and,
alone, employs 100 men. The company has completed
a massive breakwater for its extensive fleet.

It is evident that when active mining is renewed on
the Rand, South Africa, that the old system of hand
drilling by natives will give way to machine drilling,
as a measure of economy, doing away with all the list
of losses occasioned by the costly and annoying sys-
tem formerly in vogue.
$1000 a minute during its passing was only a fading
memory compared with the gorgeous and over-
shadowing present.
The progress in metallurgy is one of the greatest
achievements of applied science. In Utah silver has
been produced at a cost of 235 cents per ounce ; in
Montana copper is produced at a cost of 6 cents per
pound ; in California ore averaging 84 cents per ton
in gold has been worked at a profit of 6 cents
per ton.
Mention has previously been made herein regard-
ing the hampering effect on mining development of
the recent unwise order of the Interior Department
concerning the cutting of timber on mining claims.
The order bears particularly hard upon that worthy
class of claim owners who evince honest effort to
develop their claims. In its general wisdom and
application it resembles the time-hallowed command
not to go near the water till one has learned to
swim. The order ties the hands of many miners and
is considered simply as one of the usual official mis-
takes.
This paper is always pleased to publish declara-
tion of mining dividends — receive the name of the
company, locality, amount of dividend, and when pay-
able— without charge, and has so done through the
years, but can not undertake to announce that any
company "will pay " a dividend at any future date.
The statement as alleged might be borne out by the
fact, but it is deemed better to chronicle the dividend
announcement after declaration, and not till then. In
this, as in many other things, the character of a
paper is largely determined by the statements that
do not appear in its columns.
In January, 1898, California celebrated in San
Francisco the fiftieth anniversary of the discovery of
gold in the State, and during the past week has as
enthusiastically celebrated the fiftieth anniversary of
the admission of the State into the Union. In the
great street paintings and decorations during the
week mining scenes and appliances had first rank,
and in the procession and display the mining men of
the State had equal prominence. About 100,000
"native sons" came to San Francisco to celebrate
the event, and about 400,000 more looked on. Men
who thought the great celebration of 1898 would not
soon be outdone said that the parade that then cost
A Grave Danger.
A recent decision of a State Supreme Court in an
important mining case overrules the lower court and
gives justice by a majority vote of four to three ; that
is, four of the supreme judges think one way and
three think the other way, somewhat after the fashion
of a public vote. The three dissenting judges set out
at learned length their opinions, arguing diametri-
cally opposite to the other four equally learned
judges, and as it happens that four think one way —
one more than thinks the other way — the scales of
justice incline that way. Probably an easier and less
expensive method of securing justice in a court of
last resort would be to have a well balanced scales,
and pile the briefs, appeals, rejoinders, surrejoinders,
arguments and other legal accompaniments for plain-
tiff and defendant in either side thereof, and award
the decision to the party having the weightiest pile.
A verdict of four to three, which would not be al-
lowed in a jury box in a justice's court, is beneath the
dignity of a high appellate court and seriously tends
to undermine its influence. No State is alone in this
degrading practice ; nearly every State in the Union
has similar experiences, and even the Supreme Court
of the United States — the highest tribunal on earth
and the most respected — in some instances is itself
guilty of what might appear to be trifling with the
grave requirements of the nation, as in the case of
the decision on the income tax, where the court was
divided, one justice changing his mind over night, re-
versing his opinion of the day before, and thus giving
a bare majority to the decision.
We speak of the Supreme Court of the United
States as being "the highest tribunal on earth."
But there is a still higher one — public opinion — and
before that great tribunal all things human are
judged and by its standards all things human rise
and fall ; continue or are overthrown ; subsist or are
smashed. There never should be a dissenting opinion
in the Supreme Court of the State or nation. The de-
cision handed down should be the decision of the court,
and not of any judge ; any other course is indirectly a
blow at its own dignity, at public respect and regard
for it, and constitutes a menace to our institutions.
People have none too high an opinion of courts now
that the courts themselves can trifle with their great
positions in reducing regard for what they say to a
point even below its present condition. The dissent-
ing opinion of a judge can have but one motive, and
that is to give him his little chance of airing his indi-
vidual views and opinions. No one cares what
Brown, J., or Smith, J., thinks about the case in
point ; the question is, what is the decision of the
court, so that men may know what that decision is
and govern themselves accordingly. When the cur-
tain is raised and the public is shown the little indi-
vidual discord and unharmony, it does not tend to
enhance public respect for the source of justice which
is supposed to flow pure and undefiled.
As it is to the interest of the public that there
should be an end to litigation, so also is it to the pub-
lic interest that when a question is settled by the
highest tribunal it should remain settled for all time.
The result of the one or two or three dissenting
opinions in a Supreme Court decision is simply to
open up for future discussion, litigation and bicker-
ing, the very question that is supposed to be finally
settled by the decision of the tribunal. It must be
settled somewhere. In that Supreme Court is the
place for settlement; that tribunal was selected as
the final arbiter, and for one or two or three of those
constituting such final arbiter to publish an opinion
favoring the very cause that is decided against by
the court of which they are constituted members, is,
to say the least, poor policy. When the public reads
those dissenting opinions the public naturally gets
the idea that justice has not been done by the court;
that there is no justice about it; that it simply hap-
pens to be four to three, and that if one of the four
had happened to have a bad night, or a poor dinner,
he might have joined the ranks of the dissenters and
then the verdict would have been the other way.
This is too slight and tender a pivot upon which to
hang the scales of justice, and tends to weaken the
court in public esteem, for the common, ordinary lay
reader cannot help having the idea, however mis-
taken, that the court has lent itself to- injustice and
inflicted a wrong. Some of the dissenting opinions
are models of what they should not be in an explana-
tory and argumentative way. All that is required is
a concise, well-written summing-up of the points de-
cided and the reasons therefor, the whole being the
opinion of the court unanimously.
There are currents in the streams of time and of
national life, which though sometimes broken and
temporarily checked, yet turn and double in their
course with increasing power and injurious effect.
Such currents are flowing noiselessly yet powerfully
throughout this nation to-day and threaten to
smother in foul depths the fair growth of our institu-
tions. These currents cannot be wholly checked nor
smothered, but they need not be augmented. A
growing disregard for and disbelief in judicial de-
cisions is among the fountains that feed those cur-
rents, and the continuous practice and manifest folly
of dissenting judicial opinions and constant weaken-
ing regard or belief in the justice of judicial decisions
constitutes a grave danger.
Magnetic Separation.
The Wetherill process of magnetic separation is
receiving present attention, having a scientific basis
of calculation in its theory and practice that entitles
it to consideration. O. Bilharz of Berlin goes
into its discussion in detail, in connection with
the general subject of wet concentration,
arguing regarding substances possessing about
the same approximate specific gravity, if one
of the minerals to be separated is magnetic,
that would constitute adequate means of such
concentration. In the Wetherill process it is aimed
to utilize the smallest amount of magnetism in-
herent in any ore. In Germany the process is
chiefly applied to the separation of spathic
iron ore and zinc-blende without any prepara-
tory treatment of the material. The Fried-
richssegen Co. estimates a saving of working
expenses over former methods of about 35%. At
Franklin, N. J., the New Jersey Zinc Co. use the
Wetherill process on a large scale, separating Frank-
Unite from red zinc ore and Willemite, treating 400
tons crude ore daily. To mines producing quantities
of spathic blende the Wetherill process appears
economically applicable. It is maintained that by the
use of the Wetherill separator an argentiferous
zinc-blende containing 40% zinc can be satisfactorily
produced.
The United States Supreme Court, in the ease of
Black vs. Elkhorn M. Co. (163 U. S., 445), has decided
that " the interest in a mining claim, prior to the
payment of any money for the granting of a patent
to the land, is nothing more than a right to the ex-
clusive possession of the land based upon conditions
subsequent, a failure to fulfill which forfeits the loca-
tors' interest in the claim. To sum up as to the
character of the right which is granted by the United
States to a locator, we find : (1) That no written in-
strument is necessary to create it. Locating upon
the land and continuing yearly to do the work pro-
vided for by the statute gives to and continues in the
locator the right of possession as stated in the stat-
ute. (2) This right, conditional in its character, may
be forfeited by the failure of the locator to do the
necessary amount of work ; or if, being one among
several locators, he neglects to pay his share for the
work which has been done by his co-owners, his right
and interest in the claim may be forfeited to such co-
owners under the provisions of the statute. (3) His
interest in the claim may also be forfeited by his
abandonment, with an intention to renounce his right
of possession. It cannot be doubted that an actual
abandonment of possession by a locator of a mining
claim, such as would work an abandonment of any
other easement, would terminate all the right of pos-
session which the locator then had."
The leading mining schools and colleges throughout
the country report large accession to the number
enrolled. The drift of young men toward mining en-
gineering is illustrated in the increase in the number
taking the mining course in the University of Cali-
fornia, at Berkeley, Cal., which from 5 in 1892 has
grown to 190 in 1900.

Air at sea level at a temperature of 80° F., half filled
with moisture, has 11 grams of water vapor to each kilo-
gram of air. If the temperature be lowered 15° through
a change in the pressure, the air will become saturated
with water vapor.
A millsite can be legally located on non-mineral
land. If, before patent issues, mineral is discovered on a
located millsite, a valid mining location could be made
thereon, if solely for that purpose, peaceably and in good
faith. See page 313, "Mills and Mill Sites."
There are two kinds of men : those who go ahead
and do the things they are expected to do, or are paid to
do, and those who always have the best of excuses for
their continued failures. And the man who is good at
making excuses is rarely good for anything else.
To keep machinery from rusting dissolve one ounco
camphor in one pound melted lard ; remove the scum ;
mix in as much fine black lead as will give it "an iron
color"; clean the machinery, smear with the mixture ;
after twenty-four hours rub off and polish with soft cloth.
The dry sheet on a tubular boiler is that part of the
first sheet in a boiler that is not covered by water on one
side, and is supposed to be protected from the fire on the
other side by the brickwork in the furnace, but which is
sometimes moved on account of the arch having partially
fallen down.
Punched-SLOT steel screens are recommended
by some millmen for battery service in amalgamating
fine gold. Experiment best determines the most eco-
nomical requirements, "economy " meaning that which
gives the most profitable results.
In tho production of phosphorus by means of the elec-
trical furnace a mixture of phosphate of lime and coke
is first reduced to powder and then heated. When the
mass becomes pasty all the oponings of the furnace are
sealed except one through which tho vapor passes. This
vapor is collected and distilled.
ANY good mining machinery firm will gladly furnish a
fine catalogue or trade treatise on any specified require-
ment upon request, and, if tho writer means business,
will also furniBh detailed information as to individual
noods, with estimates. Where the contemplated plant is
of magnitude a personal visit is more satisfactory.
Steam at five pounds gauge pressure has a tempera-
ture of 228° F.; at sixty pounds gauge pressure, 307°; the
difference is 79. As the specific heat of steam is .475,
the temperature will be raised as many degrees as .475 is
contained in 79, or 165; the temperature of the steam
after it passes the reducing valve is thus 228+165=393°.
One of California's "dead rivers" is the "Big Blue
Lead," the course of which has been traced about 65
miles, paralleling the main divide of the Sierra Nevadas
and about 30 miles west. It trends at right angles to
the course of the present streams. It is capped with
lava at various depths, and has yielded about $100,000,000.
A good formula for making blue prints of maps is as
follows : Take iron and ammonium citrate saturated, 1
ounce ; water, 4 ounces. Mix this solution separately ;
then mix another solution composed of potassium ferro-
cyanide and water, 4 ounces. When desired for use, mix
equal quantities and float the paper therein for two min-
utes.
Aluminum may be silvered or gilded as follows: The
article is first covered with a coating of the following
liquid: One quart water, 2 ounces glycerine, 1 ounce
cyanide of zinc, 1 ounce iodide of zinc. After being in
contact for an hour, the article is heated red hot (752° F.).
It is then cooled, washed in water with a hard brush,
and then put into a silver or gold galvanic bath.
Patents have been granted on hardening copper, and
the claim has been made that the hardened copper can
be tempered. The last patent so granted was No. 587,861,
to J. Keuter, Aug. 10, 1897, which, in brief, is to enclose
the piece of copper to be hardened in a covering of clay,
saturate with vinegar, subject the clay containing the
copper to a high degree of heat and finally submerge the
whole in water.
As A substitute for hydrochloric acid in the Etard
process of gold recovery, Dr. Black of Otago, N. Z., says
that sulphuric acid, together with common salt in com-
bination with permanganate of potash, will extract gold
as well as the Etard process, and more quickly. In work-
ing gold ores, he claims to have extracted 92% of the
gold contents in fifteen hours by percolation and in five
hours by agitation, using the solution specified.
There is no claim to absolute correctness nor any

suitable answer to those who evidently want information

but probably the percentage of such incorrectness is as
small as in any other effort of the kind. There is no pride
of authorship, and "Concentrates " at all times takes it

With belts to transmit a given power there must be
so many cubic inches of belt pass any given point in a
given time. To do this one must either run a large belt
slowly or a small belt quickly. The product of area and
velocity must be constant. The bending force varies as
the breadth and as the square of the thickness and as
the amount of bend, a 2-inch belt offers simply twice the
resistance of a 1-inch belt ; a belt \ inch thick offers four
times the resistance of one only j inch thick. Hence a
1-inch belt of a quarter thickness has double the resist-
ance of a belt 2 inches by one-eighth. Yet they are
equal in area. In respect of shafts their resistance varies
as their speed and diameter, and their power varies as
their speed and as the cube of their diameters. Thus, a
2-inch shaft is eight times as powerful as a 1-inch shaft.
The essential difference between a marble and a com-
pact common limestone is that the first has undergone,
through the combined action of heat and pressure, just
the right degree of change, or metamorphism, to de-
velop in it crystallization and color. The essential differ-
ence between a brick or fire clay, and a cleavable slate
used for roofing, is that the first named still retains its
plastic condition as it was laid down in the form of fine
silt on a sea bottom, while the slate has, by geological
agencies, and by actual movements of the earth's crust,
become so squeezed and compressed as to have lost all re-
semblance to its former self, and to become the cleavable
article of commerce we now find it. Since these processes
of change are dependent very largely upon the actual
movements, warpings and foldings, as may be said, of
the earth's crust, and the heat and chemical action
which is thereby generated, and since these movements
only take place with extreme Blowness, whole geologic
ages being occupied in their conception and completion,
it follows, as a matter of course, that metamorphic
rocks, like granites, marbles and slates, are found only
among the older rocks, and only in those portions of the
country where this crust has been wrapped, compressed
and folded, as in the process of mountain making. In
othor words, these rocks are to be expected in their best
development only in places bordering along more or less
extensive mountain ranges.
A "siphon" whose diameter is probably as large as
any in the world is located near Boise City, Idaho, and
carries the water of Sheep creek across tho Boi6e river.
This 48-inch siphon is inverted ; is 1700 feet long, maxi-
mum depression 350 feet; cost $36,700 and took four
months and twenty days to build. Owing to the topog-
raphy of the country, everything usod in its construc-
tion had first to be raised 700 feet and then lowered 450
feet. The lightest piece of material handled weighed
3100 pounds. The whole force of water was turned on
into the siphon suddenly and at once, not gradually, as is
tho usual custom. The pipe line of the Spring Valley
Hydraulic M. Co. at Cherokee, Cal., has an approximate
inner diameter of 30 inches, discharging 52 cubic feet of
water a second. At its greatest depression the Cherokee
siphon sustains a depression of 887 feet — 530 feet greater
than at Boise City, where the greatest pressure sustained
in its lower portion is 167 pounds to the squaro inch.
In the Boise City line there never has been any tendency
to move or any leak, in spite of the pressure. To admit
of contraction and expansion without any derangement
in position, the engineer invented expansion joints placed
between each two elbows, the average movement during
the course of construction of the pipe line in all of these
expansion joints was J of an inch between the extremes
of temperature of night and day. The pipe being laid on
the side of the hill, part of it at an angle of 45°, this
movement in the pipe line, if these expansion joints had
not been used, would either have deranged the position
of the pipe or Btrained its riveting.
Wire ropes are as flexible as new hemp ropes of
equal strength and more efficient as standing ropes, be-
ing uninfluenced by weather and more durable in hoist-
ing. It is always advisable to use the largest practicable
drums, sheaves or pulleys, and to avoid high velocities, as
ropes so used will last much longer. A strain of one-
seventh of the breaking strain may be taken as a safe
working load, though for standing ropes this may be ex-
ceeded. The durability of steel wire rope is estimated to
be 30% greater than that of ropes made of iron wire. To
preserve wire rope from wear or exposure cover it thickly
with linseed oil, or with paint formed of equal parts lin-
seed oil and Spanish brown or lampblack. If used under
water or under ground a good preservative is made by
adding to one barrel of Swedish or Stockholm tar one
bushel of fresh slacked lime ; boil well, and while hot
saturate the rope. Sawdust or oat meal is sometimes
added with good effect. Wire rope must not be coiled
or. uncoiled like hemp rope. It should be unwound as
from a reel, to prevent kinking. It is always advisable
to line the grooves of the cast-iron pulleys in which the
rope runs with wood (set on end), leather or rubber. In
the use of wire rope for transmitting power this is im-
perative, because of the great velocity with which the
ropes run. Avoid, if possible, overlapping of wire rope
on drums. For shafts and elevators the load lifted
should not he more than one-tenth of the strength of the
rope. For wire rope to be exposed to intense heat wire
core may be substituted for the ordinary hemp center.
The grooves on drums and sheaves should be a trifle
larger than the rope, perfectly smooth and uniform to
the surface of the rope. Wire ropes should run around
all sheaves without chafing the sides of the grooves.
What is sometimes called "verdigris," a green or
green-gray film forming on copper plates, often showing
various colors, is due to the oxidation of copper in the
amalgam ; or it may be due partly to the effect of sul-
phates in the ore, in which case it would be partly a basic
sulphate of copper. On good electro-silver plated copper
plates it is rarely seen. It tendB to cause a loss of gold in
amalgamation. When it appears the stamps should be
hung up and the copper plates cleaned. This may be
done with ammonia, a solution of caustic soda or potash,
or a dilute solution of cyanide of potassium. After re-
moval, a little more quicksilver should be rubbed in. If
it then appears it should be removed as before, all the
amalgam scraped off and a good coating of silver amal-
gam rubbed in. If pure silver can be obtained, this silver
amalgam can be easily made by using about three parts
of silver to one of quicksilver. It requires about one-
fourth ounce of amalgam to each square foot of surface
to be amalgamated. If pure silver cannot be obtained,
a good way to make it is to use silver dollars. Dissolve
them in a porcelain evaporating dish, or any chinaware .
dish if such be not at hand, in dilute nitric acid, and
evaporate it to dryness over hot water, or a water bath.
Heat the dry mass gently till it fuses, and all the bluish
tinge in it is changed to a grayish black. When this
point is reached the copper alloy in the silver coin will
be changed to an insoluble oxide. Then dissolve all that
will dissolve in a very little water, and filter into a glass
jar. To this add the quicksilver required, and drop in a
few bright nails or other iron. The silver will be depos-
ited as metallic silver and form amalgam with the quick-
silver, and in two or three days it will be complete and
ready to use without other care. It is a good idea to al-
ways use silver amalgam on the plates, rather than pure
quicksilver, as it keeps the surface cleaner and, some mill
men say, causes a better saving of the gold.

California Crude Petroleum as a
Fuel.
By Ernest H Denicke, College of Mining, University
of California.
When crude oil was first used as a fuel the flame
was shot directly against the flues, which in a short
time seriously injured them, and it was thought that oil
could not be successfully used. It was also looked
upon as a dangerous substance, and these things, to-
gether with the usual aversion to adopting entirely
new methods, made the adoption of oil as a fuel slow.
The pioneers in the use of crude oil as fuel on this
coast probably are the California Powder Works;
oil has been burned with commercial success at their
works, near Pinole,, for over thirteen years. At first
Peruvian oil was used, but now California oil is used
and preferred for several reasons.
The oils of California can be roughly divided into
three classes : the thick, heavy oil of the Los Angeles
district; the lighter oil of Ventura, and the very light,
liquid oil of Coalinga, southwest of Fresno. The first
two are carbon oils (because of their high carbon con-
tent) with an asphaltum base, unlike the Eastern oil,
which has a paraffine base. The California oils have
some paraffine, but very little. The Coalinga oil is
peculiar, in many respects resembling the Peruvian
oil. It is remarkably light and liquid — nearly as
liquid as refined coal oil — very volatile, evaporating
nearly 10% per day, and does not seem to be a mix-
ture of several hydrocarbons, as most coal oils are.
It is a hydrogen oil.
. The gravity of the Los Angeles oil is from 12° to 19°
Baume, and sometimes as low as 10° ; the Ventura oil
is 21° to 24°; Coalinga oil about 35°, and the Peruvian
oil about 30° Baume. The volatility of the Coalinga
oil as compared to the Ventura oil is as 11 to 6. Oils
that evaporate to a marked extent are in a measure
dangerous, for the vapors are explosive ; therefore,
it is best to store crude oil in gas and oil-tight tanks
of steel.
There is difference of opinion as to which is the best
method of burning the oil, and no one method can be
called the best, because of the great variety of con-
ditions and boilers. Many patents have been taken
out on oil-burner desigus, and some of these will work
well in one furnace but fail in another. So, in select-
ing a burner, it is best to experiment, for one will
meet existing conditions better than another. Mr.
Palmer, the manager of the Union Oil Refinery, who
is an authority on fuel oil, claims that the simple pipe
burner will give the best "all-around" results. This
burner is of simple construction and can be made of a
few pieces of ordinary pipe by any good machinist.
(See Fig. 1.)

MINING AND SciENTlFlc'pRESS
Fig. 1.
The end of the outer pipe is drawn out and flat-
tened, so as to make a fan-shaped slit, a little larger
than the. cross-section of a 25-cent piece. Mr. Palmer
also claims that the highest efficiency will be gotten
out of the Los Angeles and Ventura oils when they
are forced into the burner under a head of 20-5 feet
and when about 5% of the generated steam is used to
blow the oil. These figures will vary, of course, with
the kind and quality of the oil. When 5% steam is
used with the above oils, a good "white" flame is
obtained, and a less amount of steam will give a
red, smoky flame, in which little particles of oil can
be seen burning. Different oils vary greatly in their
heating effect, dependent upon their chemical compo-
sition. In rough figures, 130 gallons of Eastern oil
— 1 ton of coal; 600 gallons = 11 cords of wood,
(maple, which is about the same as California moun-
tain oak). At the California Powder Works it was
found that 1 pound of Ventura oil = 1.7 pounds good
coal. The calorific intensity of a carbon oil is higher
than that of a hydrogen oil. Temperatures obtain-
able by burning in air with close adjustment are
about 2000° carbon and 1750° hydrogen. An excess of
air must be used hi practice.
At the California Powder Works oil is used as fuel
for making steam and in the manufacture of -chemi-
cals for dynamite making. The oil is pumped through
an underground pipe from the Union Oil Company's
Refinery, above Rodeo, and is stored in tanks made
of old glycerine tanks. These tanks have one end cut
out and are loosely closed by a wooden top, covered
with burlap. From here the oil is discharged to the
various furnaces at a head of about 22 feet. About
b% of steam is used to blow. Saving ' is effected in
both price of fuel and in the amount of labor needed.
When the furnaces are once lit they need practically
no attention, except an occasional glance to see that
the proper flame is obtained. The boilers are ordi-
nary tubular boilers, four in number. The flame is
shot under the boilers into what might be called a
brick box against a target, consisting of a grating of
firebrick. The accompanying sketch will explain.
(See Fig. 2.)
wier
Fig. 2.
Mr. Palmer recommends this type of construction,
but says that the grating of firebrick is not neces-
sary. He says that the burner should point down,
as in the accompanying sketch, and should strike
against the back of the box as a target. The effect
of the deep box is to form a vortex, as indicated by
the arrows, and gives plenty of time for complete
combustion. Complete combustion is an important
factor and deserves more attention than is given to
it. To make a test of this, it is necessary to use a
pyrometer at various places in the boiler and furnace
and to analyze the escaping gases. "When this is
done many defects of the furnace can be remedied,
the loss can be located and a great saving of fuel ef-
fected.
The only objection to the above method of furnace
construction is that it necessitates the removal of the
grate bars and a partial bricking-up of the firebox.
Should the supply of oil be accidentally stopped, the
boilers would have to be shut down so as to allow the
rebuilding of the firebox to suit Coal burning. Where
the grating and layer of firebrick are laid directly
upon grate bars, it takes half an hour at the utmost
to change back to coal burning. Of course, the lat-
ter method is not as economical as the first, but, on
the whole, it is preferable, and the slight increase in
cost may be set down as insurance on the oil sup-
The Western Sugar Refinery of San Francisco
probably uses more crude oil than any other estab-
lishment on the Pacific coast, for there 700 barrels
of Coalinga oil are burned per day, and the consump-
tion will be largely increased within the next few
months. The boiler plant consists of thirty-two modi-
fied G-allaway boilers; twenty-two of these are 6 feet
6 inches in diameter by 21 feet long, and have 271
square feet of grate surface. Each boiler has 113
3-inch tubes, giving 688 square feet of heating sur-
face. The ten other boilers are 6 feet 6 inches in
diameter by 26 feet long, have the same grate sur-
face and ninety-six 3J-inch tubes, giving a heating
surface of 1098 square feet. The plant is rated at
2540 H. P., but 4340 H. P. are obtained. There are
also three Green economizers, which heat the feed
water — two with 432 pipes and one with 360 pipes.
While coal was being burned, forced draught was
supplied by a 4x6-foot Sturtevant blower, driven by
two 111x16 engines. One of these engines was
used as an auxiliary. The oil is received in tank cars
direct from Coalinga, the cars containing from 6000
to 6500 gallons. The Southern Pacific cars are all
uniform, containing 6525 gallons, and the Union Tank
Line cars vary as above. Contract price for the oil
is $1.30 per barrel, delivered, (42 gallons per barrel,
weighing 301.33 pounds).
Seven cars are coupled on to pipes along the track
and the oil flows by gravity to a small centrifugal
pump, driven by an electrical motor, which pumps
the oil into closed steel storage tanks of 10,000 bar-
rels each. These storage tanks are surrounded by a
concrete dam wall, the space enclosed containing a
little more than the contents of one tank. From
these main storage tanks the oil flows by gravity to
a small underground tank near the fire-room. Here
the oil is pumped into two 3-inch stand pipes by two
pumps. The stand pipes overflow at 52 feet, the oil
running back to the tank; but the pumps are regu-
lated to 48 feet by Mason regulating valves, which
regulate to 6 inches. Larger stand pipes are not
allowed by the insurance companies. The boilers are
arranged in two rows, facing each other, and the oil
pipe, from stand pipe, runs along the front of them.
Each stand pipe supplies a separate row, but could
supply both rows in case of accident. At a distance
of every three boilers these two feed pipes are con-
nected with a cross-arm pipe, so that in case an acci-
dent happens to one of the boilers three of them can
be instantly cut out without stopping the plant for a
moment. This alone is a great advantage over a coal
fire, for it takes some time to " pull " a big fire. The
stand pipes, pumps and feed pipes are all set up in
duplicate, so that an accident can not stop the
plant. A network of firebrick set on edge is laid
directly upon the grate bars, and against this the oil
flame is shot. If anything should happen to the oil
supply, this network can be removed and a coal fire
started within twenty-five minutes, by actual practi-
cal trial. When oil was first used it was blown with
2% or 3% of generated steam, but, this gave an im-
perfect flame and set up a vibration. Now 8% is used
and a bunsen flame is obtained with little vibration.
As can be seen by some of the following tables, the
fire-room cost of handling the oil is less than a third
of that of coal. Besides, there are no ashes, no
smoke, absolutely no dirt, and less heat is lost by
radiation. The furnace doors are never opened, so
no cold air is allowed to strike the boiler, which makes
a difference in boiler repair. The flues need practi-
cally no cleaning, and the absence of soot gives a bet-
ter heating power. When coal was used as fuel,
twenty-six firemen were employed ; now, twelve are
needed. Oil fuel allows the use of a peculiar little
device which makes a saving in fuel. It is known as a
" retarder," and consists simply of a strip of twisted
sheet iron, which is placed in the boiler flue. (See
Mining and scientific press.
Fig. 3.
Fig. 3.) This not only retards the draught and al-
lows the flame more time, but also revolves and
"stirs," if the term may be used, the heated gases.
Gases are very poor conductors of heat, and, if they
are allowed to go straight through the flues, only a
little more than the outer part of the currents is
cooled ; but the retarders twist the gas currents,
bringing more of the heated gas into contact with
the flues. They can not be used in a coal fire on ac-
count of the soot.

The Estimation of Copper in Ores by
the Modified Cyanide Process.
Written for the Mining and Scientific Press.
The general activity in copper mining of late years
has revived interest in the methods for determining
the amount of copper in copper ores. After several
years' experience in actual practice, and in the class
room as a teacher, I am convinced that the method
hereinafter described is the simplest and most accu-
rate method known for determining the amount of
copper in an ore. The majority of persons called
upon to determine copper are not expert chemists,
and it is with reference to this class of workers that
I make the above statement.
There are several well-known methods for quanti-
tative copper analysis, the most generally accepted
method being the electrolytic method.
Electrolytic Method. — This is generally credited
with being a more reliable method than it really is.
For years it has been considered the standard
method, and it may still be so considered when manip-
ulated by acknowledged reliable chemists. The fol-
lowing list of restrictions and limitations will make
the latter statement more convincing :
1. A uniform voltage must be maintained through-
out the determination.
2. Do not use too high a voltage — it will deposit
spongy copper. Zinc will also be deposited if pres-
ent above 3%.
3. Do not stop before all the copper is deposited.
4. Do not continue after all the copper is deposited.
5. Do not have the solution too strong with nitric
acid — it will keep some copper in solution indefinitely.
6. Do not use too much sulphuric acid — it will de-
posit spongy copper.
7. Remove bismuth if present, otherwise it will
deposit with the copper.
8. Lead is deposited with copper if present.
9. Arsenic must be removed or it will be deposited
with the copper.
It is evident that one must know all the mineral
constituents of his ore, and also the approximate
amount of copper in it, in order to be certain of his
result. This is requiring too much of the average
chemist or assayer.
The Iodide Method. — This is an excellent method
and very accurate, but it is cumbersome in the hands
of some assayers and unskilled chemists.
The Ordinary Cyanide Method. — In this method
iron, which is usually present in copper ores, is pre-
cipitated by ammonia hydrate and filtered out. The
precipitate of iron hydrate always contains consider-
able copper, making the result low. Besides, if an
excess of ammonia hydrate be used, it will make the
result too high. Arsenic, zinc, antimony, etc., must
be removed. Too much nitric or hydrochloric acid
lower the result. If the iron precipitate be redis-
solved and reprecipitated it will produce an excess-
ive amount of ammonium nitrate (or chloride) which,
in turn, will react on the cyanide, giving too high a
result.
The Modified Potassium Cyanide Method. — This
is sometimes called the "aluminum strip" method.
I have added several precautions and details of my
own which I trust will be of service.
This method is dependent upon the following chemi-
cal reaction, in which the copper unites with the
potassium cyanide, forming the double salt of copper-
potassium-cyanide :
CuSO, + 4KCN = CuK2(CN)4 4- K2S04

pbate reacts with four molecules of potassium cya-
nide. The one atom of copper weighs 63 microcriths
uml the four molecules of cyanide of potassium weigh
260.4 miorocriths. K = 39.1: C = 12; N = 14.

evident, therefore, that if a solution of ECN
be made to contain 1.1 grains of KCN to each 100
O.C. of solution and 1 gram Of Ore be taken for analy-
sis, each c.c. of ECN solution required in the titra-
tion will represent 1"„ of copper in the ore.
As chemically pure KCN cannot be obtained, it is
necessary for us to use chemically pure copper with
which to standardize the ECN solution.
The details of the various operations are as
follows :
To Make the Standard Copper Solution. —
1. Wash a little over 1 grain of chemically pure
copper iii hot, moderately concentrated nitric acid.
Wash several times in distilled water and dry slowly,
so as not to form a coating of copper oxide on the
pieces.
2. Weigh out exactly 1 gram and dissolve in 25 o.C.
of C.P. nitric acid. Use a tall beaker and keep it
Covered with a watch glass to prevent the spray
falling outside (a frequent source of loss). Heat may
be used.
3. Wash the solution into a litre llask and dilute at
once to exactly 1 litre (= 1000 c.c), using cold (1)3°
Fahr.) distilled water. Mix well.
4. This standard copper solution can be kept in-
definitely in a bottle for future use. Do not add any
more water to it in any case, as it is your stand-
ard.
Tiif. Potassium Cyanide Solution. —
1. Dissolve about 42 grams of the best commercial
KCN in 1 litre of distilled cold water (63° Pahr.).
2. Decant or filter out any "pus" or sediment,
standardize and bottle for future use. Keep it in a
dark place.
Though the solution gradually loses strength, owing
to the decomposition of the KCN, it will not mate-
rially change in one month if distilled water has been
used.
Standardizing the KCN Solution. —
1. Take two 100 c.c. burettes. Wash one out with
the standard copper solution and the other with the
KCN solution. Discard the washings.
2. Pill the Cu burette with standard copper solu-
tion and run off to the zero mark. (A graduated cyl-
inder can be used in place of the burette for the cop-
per if desired.)
3. Place at least 15 c.c. of the KCN solution in the
KCN burette.
4. Run the 100 c.c. of copper solution into a beaker
and add just enough ammonium hydrate to produce a
deep blue color — no more — say 5 c.c.
5. Add about 7 c.c. or 8 c.c. of the KCN solution at
once, then continue by adding only a drop at a time,
carefully stirring the copper solution to insure a
thorough admixture, until the blue color disappears
and a pink color appears. A white background will
assist in determining the end of reaction.
6. Make several confirmatory tests.
7. Multiply the result by 10 to ascertain how much
KCN solution would be required for the entire gram
of copper. The result will usually be from 95 to 105.
This number we will call the " cyanide standard num-
ber." For greater accuracy 200 c.c. or 400 c.c. of
standard copper solution can be used in standardiz-
ing the KCN.
The Ore Sample. —
1. Pulverize a dry sample of copper ore to about
60 or 80 mesh and weigh exactly 1 gram.
2. Place it in a deep evaporating dish on a sand
bath and add 10 c.c. to 15 c.c. of strong HN03.
Cover with a watch glass, but place a glass rod un-
der the glass to permit evaporation.
3. Evaporate nearly or quite to dryness and add
5 c.c. of HC1.
4. Evaporate nearly to dryness.
5. Add 10 c.c. strong H2SO,.
6. Evaporate till very copious ; choking fumes are
given off, indicating that the H„SO., has expelled all
the HNO;, and HC1. Enough H.2SO., should be added
to produce strong fumes without evaporating to
d ry ness.
7. Cool and add about 50 c.c. or 00 c.c. of water.
8. Filter into a tall beaker and place on a wire
gauze over a bunsen flame.
!). Add a strip of metallic aluminum, 2"xl//xi" in
size and bent thus : |
10. Boil five minutes (not simply "boiling hot").
This will precipitate all the copper in the metallic
state.
11. Add about 25 c.c. of cold water.
12. Decant through a filter, retaining as much of
the precipitated copper in the beaker as possible.
Wash the copper three times by adding distilled
water and decanting through the same filter paper.
Throw away the filtrate and washings.
13. Carefully place the aluminum strip on the filter
paper and put the beaker containing the copper un-
der the filter. With an ink dropper or a pipette
drop strong HNOs on all sides of the aluminum strip
to dissolve off all adhering copper. Also dissolve all
copper off the filter paper, then add just sufficient
IIM > in dissolvi per in the beaker below, but
il" tint add an excessive amount,
14. Wash filter paper and aluminum strip with dis-
tilled water and dilute the solution to T."i O.C. Or 100
C.C, according to the richness of the ore.
15. I'ool thoroughly.
lti. Add just enough NH,OH to give a deep blue
color — no more.
17. Place the beaker on a sheet of white paper,
under the KCN burette, and add KCN till tho color
just begins to fade.
I If there is a heavy precipitate of aluminum hy-
drate, quickly Biter and wash filter, and then con-
tinue titrating to end of reaction. It is better to
remove the precipitate after adding nearly a suffi-
ciency of KCN rather than to remove it before
beginning to titrate. ]
18. Finish the titration to the same shade of pink
Obtained in standardizing the KCN solution.
111. Multiply the number of c.c. used by 100 and
divide by the "cyanide standard number." The quo-
tient will be the per cent of copper in the ore.
Examples.— Suppose, in making up our standard
KCN solution and testing the same, 100 c.c. of our
standard copper solution required 9.4 c.c. of KCN,
then 9.4 X 10 = 94, our "cyanide standard number."
Suppose 1 gram of ore be treated and that 31 c.c.
of I\CN is required in the titration. We then make
use of the following proportion :
94 c.c. : 100% : : 31 c.c. : X%
100 X 31
94
= 32.9%
ANOTHER Example. — Suppose our " standard cya-
nide number " is 102, and that a sample of copper
ore required 15.3 c.c, 2 grams of ore being taken for
a sample (presumably a low-grade ore) :
102 c.c : 100% : : 15.3 c.c. : X%
15.3 X 100
102 X 2
= 7.1%
Remarks. — In reference to paragraph 6 above, it
should be borne in mind that sulphur trioxide fumes
must be evolved very copiously to insure the absence
of all HNOs and HC1, which, if present, will prevent
the precipitation of the copper by the aluminum
strip. If you evaporate to dryness to get the fumes,
some of the copper may assume an insoluble form.
If, in filtering under paragraph 8 above, the filter
paper is destroyed, it is evidence you did not dilute
the retaining HjSO., sufficiently.

Branch Carrying Pipes.
The carrying capacity of a pipe is not in propor-
tion to its internal area. A pipe 4 feet in diameter
has only four times the area of a pipe 2 feet in diam-
eter, and yet the 4-foot pipe will carry 5.60 times as
much fluid as the 2-foot pipe, under the same condi-
tions of length and head. In other words, a 2-foot
pipe will carry 17.6%, or nearly 18% as much as will
a 4-foot pipe. This proportion of carrying capacity
does not hold good for smaller pipes of the same pro-
portionate diameter. A 1-foot pipe has only 16.6%
of the carrying capacity of a pipe 2 feet in diameter,
and a 1-inch pipe will carry only 14% as much as a
2-inch pipe. A 6-inch pipe can have 15% of its ca-
pacity carried by a 3-inch pipe, 23% by a 33-inch
pipe, 34% by a 4-inch pipe, and a 24-inch pipe will
cany thirty-eight times as much as the 6-inch pipe.
In taking branches from a main, it is advisable that
the sum of the percentages of the carrying capacities
of the branches should be 100% or more. Referring
again to a 6-inch main, if it be divided into two
branches — one 4 inches and the other 5 inches — the
carrying capacities of the branches would be re-
spectively 34% and 63% of the 6-inch pipe. Thus
provision is made for only 97%, and there would be
slight additional friction from the point of diversion
of the branches. If the branches be made 4J and 5
inches, the percentages are respectively 47 and 63,
their sum 110, and from the junction the flow would
be considerably more free than in the first case.
California Oil Wells.
There were on Sept. 1st 1439 rigs and wells drill-
ing reported in all fields. The greatest increase in
new work is noticeable in the central district. The
Los Angeles field comes second in number of wells
begun. The northern district, including San Mateo,
Monterey, Colusa, San Benito, Humboldt and Contra
Costa counties, shows a gain in new work. In the
central district, which includes Fresno, Kern and
Kings counties, on Aug. 1st ninety wells were re-
ported drilling and rigs up. This number was in-
creased during the month to a total of 176, of which
91 are in the Kern river field alone and 29 in the
Sunset field. In the coast district, which covers San
Luis Obispo, Santa Barbara and Ventura counties,
forty-one wells were reported under way Aug. 1st;
on the 1st inst. this district showed ninety-two rigs
and wells drilling. The southern district, including
Los Angeles, Orange, Riverside and San Diego
Counties, showed 120 rigs and wells drilling Aug. 1st.
This number was increased during the month by 32,
making a total of 152 under way.
Location of Mining Claims.
Under the Act of Congress (Rev. St., Sec. 2319-
2324), a lode claim can not exceed 1500 feet in length
by 000 feet in width, and should be in the form of a
parallelogram having its side lines equidistant from
the center of the lode, with end lines parallel to each
other.
A lode is a zone, belt or body of quartz or other
rock lodged in the earth's crust, and presenting two
essential and inherent characteristics, viz: (1.) It
must be held in place withiu or by the adjoining rock;
and (2) it must be impregnated with some of the min-
erals or valuable deposits mentioned in the statute,
and which will authorize the location of a lode
claim.
In locating a mining claim all that the statute re-
quires is that the location shall be distinctly marked
on the ground so that its boundaries can be readily
traced. Whether any markings have been made, and
and whether they are such that the boundaries of
the location can be readily traced, are questions of
fact.
The statute does not require any record of the loca-
tion, but when one is made it prescribes what it shall
contain, viz : that the name of the locator, the date
of the location, and such description of the claim by
proper references as will identify the claim, the prin-
cipal object of the record is the identification of the
claim ; and, if, considering everything it contains,
the name of locator, date and description by refer-
ence to same natural object or permanent monu-
ment, the claim can be identified, the record is suf-
ficient.
No notice of location is required by the statute, but
when the same is posted on the ground it must be
considered as a marking to aid in tracing the
boundaries. When such notice contains a description
of the claim and is recorded, it operates as con-
structive notice that the locator claims the ground
described. The description as shown by the record
will ordiuarily bind the locator as to the locus of the
claim ; but where the distances and courses set out in
the description vary from the monuments or mark-
ings made on the ground, the latter prevail and will
determine the locus of the claim.
The effect of a valid location is to segregate from
the public lands the grounds located, and the prior
location gives the prior and better right. A valid
location vests in the locator the exclusive right of
possession and enjoyment of the ground located, to-
gether with all the lodes therein.
The maxim that one may recover on the strength
of his own title does not apply in the case of a naked
trespasser or intruder, although the party in pos-
session may have a defective location ; in such case
the latter's possession alone is sufficient to maintain
ejectment.
Mills and Mill Sites.
To the Editor : — Will you please answer the fol-
lowing and oblige a subscriber :
A owns a mill on a certain creek but does not own
the ground on which the mill stands. B locates a
millsite, taking in A's mill, and gives him written
notice to remove the mill within thirty days, which
A fails to do. B now claims the mill. Is he right ?
Cherry Creek, Nev,, Sept. 4. Prospector.
The question can not be answered from the stand-
point of adjudicated cases except tentatively. The
land being non-mineral it might have been appro-
priated by A, either in connection with a located lode,
or under the last clause of Section 2337 of the Re-
vised Statutes, relating to the construction of a
quartz mill or reduction works regardless of lode
ownership. In the latter ease it would seem that
the construction of a mill upon the land would segre-
gate it from the public domain, and prevent its relo-
cation by others for millsite purposes. Certainly A
is not a trespasser when he goes upon the land and
constructs the mill if the land is public and non-
mineral ; he has rights which the Government would
recognize. It is quite likely that the relocator would
also have to recognize these rights. The case is
quite different from the location of a millsite on min-
eral lands which are subsequently located by a pros-
pector as a mining claim, in which instance the mill
would probably fall to the mining locator.
Questions of this character are extremely close
and should be solved by a good lawyer, who should be
put into the possession of all the facts. As a matter
of first impression we would say that A being the
first comer, the land being non-mineral, the erection
of the mill secures to A the right to the occupancy of
the land as against B, seeking to claim the land for
the same purposes. Under such circumstances B
could not take A's mill or compel him to remove it,

Boiler Explosions — Cause and
Remedy.
The only explosive material about a steam boiler is
water. Water, when superheated, will explode upon
a sudden removal of pressure with a force equal to
that of dynamite.
The boiling point of water varies with pressure. In
a vacuum water boils at 70° F. sensible heat. Under
atmospheric pressure it boils at 212° F., and cannot
be made hotter unless confined under additional pres-
sure, because the escaping steam carries off the heat
as fast as fire can impart it. In a steam boiler under
10 pounds pressure it boils at 241° ; 50 pounds, 300° ;
100 pounds, 340° ; 200 pounds, 389°.
Water when heated to the boiling point requires 966°
additional heat to change it from the state of water
to the state of steam. This change is substantially in-
stantaneous at all pressures. As each molecule of
water absorbs the last of the 966° it instantly explodes
into steam. As the last degree is'absorbed, cohesion
is overcome and repulsion becomes the predominant
power. The change of steam to water is also instan-
taneous. Steam remains in its new state only so
long as it retains the 966° of latent heat, and the
moment it is at full volume, with only 212° of sensible
heat, parts with one of these degrees of latent heat
it returns to water.
The explosion of water is similar to that of gun-
powder in some respects, but different in others.
Each grain of gunpowder passing from the solid to
the gaseous state explodes when it has absorbed a
certain degree of heat ; so with water. Each mole-
cule of water, at the instant it has absorbed 966° of
heat above the boiling point, explodes and passes
from water into steam. The expansive quality of the
two is different, powder increasing in bulk 800 times,
while water increases 1720 times. The mode of ex-
ploding and the general result, large and sudden in-
crease of bulk, are similar. In other respects they
differ widely. The explosion of powder is by chemi-
cal action ; the explosion of water is a physical
change only. Water differs widely from powder and
all other explosives in another remarkable particu-
lar. Only a portion of the water may explode — one
molecule, the half, or the whole mass. These various
amounts in exploding produce results ranging from
violent explosions to mild ruptures and the safe oper-
ation of the boiler.
When a grain of powder starts to go from the solid
to the gaseous state no power can stop it. It may
be confined, but combustion, once begun, goes on to
completion. So with a molecule of water. It may be
put under such a pressure that it will not fully ex-
pand, but, once begun, it changes its state from
water to steam.
The true source of the development of the great
destructive power in a steam boiler is the sudden
concentration of the sensible heat in the water above
212° (or above 70° in case of a vacuum caused by the
condensation of steam) into a part of the molecules
of water, passing into them the 966° neces-
sary to change them from the state of water to the
state of steam. That the stored heat in a boiler con-
centrates to form steam is shown by familiar experi-
ments: As, for instance, causing water at less than
212° to boil by placing it in a vacuum; or by merely
condensing the steam over heated water in a bottle.
Again, take a steam boiler under a pressure of 100
pounds and a corresponding temperature of 340°.
Remove the fire, and the formation of steam will
cease. After a short time raise the safety valve,
and the water will begin to boil, and generate and
give off steam continuously as the pressure is re-
duced, until a temperature of 212° is reached, and
enough steam will be thus generated and blown off to
fill the boiler many times.
These tests show that the boiling point of water is
lowered by simply diminishing the pressure; that sen-
sible heat above 70° stored in the water concentrates in
a part of the molecules of water, giving to them the
966° necessary to change them into steam. The water
ceases to boil, no heat is applied, and by merely re-
ducing the pressure the water again boils. The 966°
above the boiling point necessary to cause ebullition
are not absorbed from the fire at the instant the
water begins to boil the second time. They are
already stored up in the water.
Take a boiler containing 10,000 pounds of water at
a pressure of 200 pounds and corresponding temper-
ature of 389°. Suddenly reduce the pressure to 50
pounds per square inch, under which pressure water
explodes at 300°. There are stored in each of the
10,000 pounds of water 89° of sensible heat above the
exploding point — in the aggregate 890,000 thermal
units, enough to convert 921 pounds of this super-
heated water into steam. In an instant these 89° of
sensible heat in each pound of water are absorbed by
the molecules of water at the surface and for a con-
siderable depth, and suddenly these 921 pounds of
superheated water explode into steam.
Thus it will be seen that there is sufficient destruc-
tive power stored in the boiler when thus put in
action to cause an explosion. If the reduction of
pressure caused by the withdrawal of steam be mod-
erate, and such draft be continuous and uniform,
there will be no danger ; but if the draught is con-
siderable in quantity and instantly checked, the
nascent steam thus suddenly formed and thus sud-
denly checked will give an impact or striking blow
upon the shell of the boiler, the aggregate force of
which is equal to the weight of the water before it
passed into nascent steam multiplied by the square
of the velocity with which it strikes.
The instantaneous check to the exploding water
acts upon the boiler with the same effect as that pro-
duced by quickly closing the valve of a water-main.
In the one ease it is the weight of the falling water,
and in the other it is the force of exploding water,
but the striking effect of the blows is the same and
is measured by the same rule.
Take a boiler 48 inches in diameter, 19 feet long,
and place in it 10,000 pounds of water. Then raise
the temperature to 400°, and the corresponding pres-
sure will be about 235 pounds. About ^J^ part of
the water, or 50 pounds, passes into steam, occupy-
ing the balance of the space of the boiler, about 86
cubic feet. The temperature is 188° above 212°.
The amount of sensible heat, above 212°, stored in
the remaining 9950 pounds of water is 1,870,600
thermal units, equivalent in mechanical energy to
1,444,103,200 foot-pounds. Suddenly reduce the pres-
sure from 235 pounds to normal. At 235 pounds it
required 400° to evaporate water, at normal pressure
only 212° — a difference of 188°. There are stored in
the boiler 1,870,600 units of sensible heat above 212°,
enough to convert about 1936 pounds of the remain-
ing water into steam, which would occupy, under 235
pounds pressure, about 3000 cubic feet of space.
Rating the velocity of the nascent steam at one-half
the velocity of full steam discharged into the air
(1967-^2), would give a striking force of over 23,000
pounds per square inch upon the shell of the boiler.
Starting with a pressure of 25 pounds, and a cor-
responding temperature of only 269°, only 57° above
212°, the amount of sensible heat stored above 212°
would be 567,150 thermal units. Reduce the pres-
sure to 0, corresponding to 70°, and the 9950 pounds
of water would contain 1,980,050 thermal units, suf-
ficient to convert 2049 pounds of water into steam.
Rating the weight of the water and the velocity of
the nascent steam as in the last case, this would give
a striking blow of over 24,000 pounds per square inch.
Take a boiler half full of water, under a pressure of
200 pounds and at 389°, and suddenly inject into the
steam space a quantity of cold water. Condensation
is instantaneous. Instantly the superheated water
at 389° is in a vacuum where it will explode at 70°.
Under these circumstances a large portion of the wa-
ter will explode into steam, and, whether one-quar-
ter, one-half, or the whole, the striking force will be
sufficient to tear into shreds any boiler ever made.
If the withdrawal of steam is slight, even if followed
by a sudden check, no damage ensues with boilers of
the usual tensile strength ; but if the withdrawal be
considerable and the check instantaneous, an explo-
sion follows. With the varying degrees of draught
and sudden check come violent explosion, and mere
rupture.
The distinction between rupturing and exploding is
sometimes overlooked. When a boiler gives way at a
weak point, resulting in damage, it is often called an
explosion. When ruptured by mere pressure, the
force exerted upon the shell being gradual and uni-
form, the weak point yields while the balance remains
intact. Serious damage may result, but a uniform
and unobstructed flow of steam never produces the
phenomenon properly called an " explosion."
With an explosion the actual destructive force ex-
erted is not measured by the tensile strength of the
boiler nor by the regular pressure of the steam. The
force is far in excess of either — five, ten, and often
twenty times as great ; an immense aggregate con-
cussive and destructive force, that tears asunder the
weak and the strong parts at the same instant and
demolishes everything within a large radius.
Some writers on steam boiler explosions, in ac-
counting for their violence, make the mistake of com-
mencing the calculation at a point of time after the
rupture has commenced. The fact is there is violent
internal action at the instant preceding the actual
rupture of the boiler, and the rupture is the result of
such action. Rupture may be caused by the mere
pressure of steam, but it is usually caused by an in-
ternal concussive force. It is illogical to say that
boilers are ruptured or burst by mere pressure while
working with a pressure of only one-fifth their actual
tensile strength.
The writer's solution of a steam boiler explosion is
this : The water in the boiler, under pressure, is
superheated and possesses a highly expansive power.
Upon a sudden removal of the pressure, without a
corresponding reduction of the temperature, it starts
into violent evaporation. This mass of nascent steam
is checked by coming in contact with the solid and
unyielding shell of the boiler. The result is that the
aggregate force of this nascent steam strikes every
square inch of the shell of the boiler at the same in-
stant and with the same force, and with a power far
in excess of the tensile strength of the boiler ; and,
moreover, this force is augmented at the instant the
shell gives way by an immense reserve power caused
by the further evaporation of the water in the
boiler.
The writer's remedy is a simple one and consists in
the construction of a boiler with a partition plate or
diaphragm dividing it into two compartments, the
lower containing the water and the upper containing
the steam only. The steam passes from the lower to
the upper compartment through numerous small per-
forations and a number of small valves in the dia-
phragm. The aggregate openings of the valves and
perforations should be less than the valve through
which the engine is supplied. By this means the
pressure upon the surface of the superheated water
is kept approximately uniform, and all sudden explo-
sions of any dangerous quantity of water into steam
and consequent striking blows are avoided.
The perforations and valves vary with boilers of
different size. The aggregate area of all the per'
forations and valve orifices should be about 10% less
than the area of the steam-port. In ordinary sized
boilers there should be one perforation of i-inch in
diameter to each horse power, rating 10 square feet
of heatmg surface to the horse power, and such num-
ber of valve orifices of about 2 inches in diameter as
to make up the balance of the aggregate area.
This lessening of the aggregate area 10% below
that of the steam-port will give a very slight diminu-
tion of pressure in the engine with steam working at
full stroke, but will give practically full pressure at
every other point of cut-off. There must be two
steam gauges used, one connected with the water
space below and one with the steam space above the
diaphragm. When the boiler is set and ready for
use such small valves should be closed. As the steam
is generated and the engine put in operation at its
full capacity, any additional steam required is ob-
tained by gradually and partially opening such valves
until the required amount is liberated and ascer-
tained, when such valves are set, and need but little
further attention. In thus arranging such valves,
particular attention should be paid to the steam
gauges. The valves should be opened only to that
extent at which the pressure upon the superheated
water in the lower compartment, as shown by the
gauges, remains approximately uniform with that in
the upper, with the engine in full operation. Thus
arranged, any unusual and sudden withdrawal of
steam from the upper chamber is attended with no
possible danger.
Boilers thus constructed and arranged are pro-
tected against explosions, whether the water wholly
or partially fills the water compartment. If wholly
filled, a sudden reaction of pressure in the steam
compartment can instantly effect only the surface of
the water to the extent of the aggregate area of the
perforations and valve orifices, and no dangerous
quantity of water can be thus exploded. As the pres-
sure upon the water below the diaphragm is thus
slightly reduced, small portions of water pass into
steam and maintain uniformity of pressure.
Assay of Copper Materials for Gold
and Silver.
At the Washington, February, 1900, meeting of
the American Institute of Mining Engineers, L. D.
Godshall read a paper on "The Assay of Copper Ma-
terials for Gold and Silver," which appeared in the
issue of this paper of March 24th. In the issues of
April 14th and May 12th also appeared technical
reference to the same subject. In a discussion of
Dr. Godshall's paper, A. R. Ledoux says:
The so-called "combination method" is generally
used in assaying bar copper for silver. It has been
modified from time to time. Briefly outlined as now
practiced, it is as follows: One A. T. of the borings
is dissolved in dilute nitric acid. When solution is
complete, the liquid is boiled and then filtered to re-
move gold. The filtrate is treated with sufficient
salt solution to precipitate all the silver, but avoid-
ing any unnecessary excess. The liquid is allowed to
stand over night and next morning the silver chloride
is collected on a fresh filter, which, together with the
paper containing the gold and insoluble matter, is
scorified and cupelled. Formerly many assayers
added sulphuric acid to the nitric acid solution of the
copper and silver and then acetate of lead, thus pro-
ducing a heavy precipitate of sulphate of lead, which
was supposed to entangle the silver chloride and pre-
vent it from passing through the filter. As a matter
of fact, the use of sulphuric acid and lead salts is en-
tirely unnecessary. Very few assayers now make
use of them. If it is not possible to let the silver
chloride settle over night, accurate results may be
obtained by stirring the liquid vigorously with some
form of mechanical stirrer for half an hour. The
silver chloride may then be easily filtered without
fear of any of it escaping through the filter. The
same result may be attained by blowing air through
the liquid. It is quite possible to make an accurate
assay by this method in three hours. In some cases,
noticeably those in which the copper is very free from
impurities and the gold contents small, the correct
gold assay may be obtained by parting the bead ob-
tained by this process. In many cases, however, the
gold assay obtained by the above process is too low,
even though the gold be removed from the liquid by
filtration before adding the salt solution. It would
appear that sometimes the gold is present in the
copper in some combination which is soluble in nitric
acid or strong nitrate of copper solution. However,
it may be, and frequently is, necessary to resort to
the " all- fire method" to obtain correct results.
This method consists in weighing out a number of
1 to 10 A. T. portions — usually ten — and scorifying
them with lead until most, of tfre copper is removed,

then cupelling the lead buttons cither separately or
uniting them live and live, rescorilyine ami then cu-
pelling. This method is expensive and laborious, in-
volving many scorifications and the use of much test
lead. The first scorification must be conducted at a
high temperature, ami tin' operations consume a
great deal of time and muflle room. But the gold ob-
tained is usually appreciably more than can be ex-
tracted by the combination method, though it does
not seem to bear any fixed ratio to it even in the same
class of copper. In general, in W'\, to 98% copper,
containing from one to live ounces of gold per ton,
the 'all lire" results will be from 0.1 to 0.3 ounce
higher than can be obtained by the combination
method. Any method that would give correct gold
and silver results on all classes of bar copper at one
operation, and that would avoid the tedious and ex-
pensive operations of the all-fire process, would find
ready acceptance among assayers. The method de-
scribed by Dr. Godshall seemed to offer some possi-
bilities in this direction. To test the practical ac-
curacy of this method, comparative assays were made
in ray laboratory on three samples of bar copper,
using the " combination method " for silver and the
"all fire" process for gold, alongside of Dr. God-
shall's method. Some preliminary experiments were
made by the new method to obtain a knowledge of
any peculiarities that might be developed. The pro-
cess of assay was as follows: One A. T. of borings
dissolved in dilute nitric acid (90 c. c. strong to 100
c. c. of water). The solution was then evaporated
to expel free nitric acid, a little sulphuric acid (20
c. c.) was added, and the evaporation continued.
Finally the copper salts were dissolved in hot water,
the solution diluted to 800 c. c. and allowed to cool.
Then sulphuretted hydrogen was passed rapidly into
the liquid for two minutes. A heavy black precipi-
tate of sulphides was produced, which settled rapidly,
leaving a clear blue solution. The liquid contain-
ing the precipitate was stirred rapidly and then
allowed to settle for about half an hour, and finally
the sulphides were filtered off. The filtrates in
most cases gave no visible reaction for silver ;
sometimes, however, silver was not completely pre-
cipitated by the sulphuretted hydrogen. No reason
was developed why this should be the case, as those
solutions which contained silver had apparently been
treated exactly like those which did not. The assays
noted below did not show any reaction for silver when
the filtrate was tested with salt solution. The cop-
per sulphide containing the silver and gold was dried,
the papers burned in scorifiers, and the residue scori-
fied with fifty grammes of test lead. The results
were as follows :
SILVER— OUNCES PER TON.
Godshall Combination
Method. Method.
No. 1 67.70 67.20
No. 2 57.20 58.80
No. 3 59.00 59.30

Godshall All Fire
Method. Method.
No. 1 2.28 2.42

From the foregoing results one would infer that the
new method can give good results on silver. But the
gold assays are too low, being about the figures which
would be obtained by parting the silver beads ob-
tained by the "combination method." The new
method does not seem to possess any advantage over
the " combination method " in point of speed. When
the silver chloride is stirred well or "blown down"
with air, it can be filtered off as quickly as the sul-
phide precipitate. On the other hand, the new
method requires the use of sulphuretted hydrogen,
which is a noxious and troublesome reagent to handle
on a large number of samples at the same time.
Cabell Whitehead, Washington, D. C. (communica-
tion to the secretary) : Dr. Godshall has placed the
metallurgical public under great obligations by reviv-
ing the subject of the determination of gold and silver
in copper-bearing materials. Several years ago Dr.
Ledoux brought this subject before the Institute in a
valuable paper, but I have always felt that the sub-
ject was not as fully discussed at that time as might
have been done with profit. It was clearly shown by
the results then reported that the "combined"
method yielded lower gold results than the fire assay.
This was supposed to be due to a solution of some of
the gold, occasioned by the impurities of the nitric
acid used ; and Dr. Godshall seems to have accepted
that view. Since then, I have determined by experi-
ment that when the acid is chemically pure, a partial
solu tion of the gold takes place, probably by reason
of the formation of nitrous acid during the process of
solution, and that the reaction, though manifested in
smaller degree, is closely allied to that which occurs
when platinum, in the form of an alloy, is dissolved in
nitric acid. This being admitted, it is clear that the
" combined " method cannot be relied upon for gold.
We were therefore greatly in need of a method such
as the one proposed by Dr. Godshall. I have experi-
mented with it, and find that, under certain condi-
tions, excellent results are obtained. The conditions
for satisfactory working are given in his paper ; but
I do not think the danger points are clearly marked.
I found that, when the solution was cold, and practi-
cally free from nitric acid, the precious metals were
perfectly thrown down with a very small amount of
HaS. In such cases, the amount of copper to be re-
moved by scorification and cupellation was small, and
gave no trouble ; but when the copper solution con-
tained much free nitric acid, or was hot, large
amounts of H,S were required to complete the pre-
cipitation ; that it had to be followed by a rapid fil-
tration ; and that, even then, the solution frequently
contained traces of silver. The removal of the nitric
acid by evaporation with sulphuric acid is a matter of
considerable difficulty, as I believe all who have tried
it will admit. This and the careful attention required
in making the H2S precipitations are the chief objec-
tions to the method. I have modified it with good re-
sults as follows :
I dissolve in HNOa; dilute and make faintly alkaline
with ammonia ; then make acid with acetic acid. I
then add a solution of hyposulphite, sufficient to pre-
cipitate about 100 milligrammes of copper. After
thoroughly mixing the solutions with a stirring rod,
the beaker is boiled for five minutes, or until the Cu2S
collects. This precipitate is cupelled in the usual
way. With this modification of the proposed method,
I believe there remains only one objection, viz., the
necessary scorification of a product high in copper.
I have been working with some success to overcome
this difficulty, and I hope to publish the result of my
efforts hereafter.

Mine Bell Signals.
TO the Editor: — 1 note an illustrated article in your
issue of the 1st about the Lowell & Arizona C. M. & S.
Co. 's plant at Bisbee, Arizona, in which the writer says
they are using the Montana code of bell signals in the
mine, which gives satisfaction. Hasn't California a code
of bell signals ? If so, and it is possible, I would like to
have them compared. W. W. S.
Nevada City, Cal., Sept. 5.
Following are the two codes in full, as furnished
officially : the best answer to the above. The Cali-
fornia system was legalized May 1, 1893 ; the Mon-
tana code went into effect June 1, 1895 :
CALIFORNIA CODE OF MINE BELL SIGNALS.
1 bell, to hoist. See Rule 2.
1 bell, to stop if in motion.
2 bells, to lower. See Rule 2.
3 bells, man to be hoisted ; run slow. See Rule 2.
4 bells, start pump if not running, or stop pump if
running.
1 — 3 bells, start or stop air compressor.
5 bells, send down tools. See Rule 4.
6 bells, send down timbers. See Rule 4.
7 bells, accident ; move bucket or cage by verbal
orders only.
1 — 4 bells, foreman wanted.
2 — 1 — 1 bells, done hoisting until called.
2 — 1 — 2 bells, done hoisting for the day.
2 — 2 — 2 bells, change buckets from ore to water, or
vice versa.
3 — 2 — 1 bells, ready to shoot in the shaft. See
Rule 3.
Engineer's signal that he is ready to hoist is to
raise the bucket or cage two feet and lower it again.
See Rule 3.
Levels shall be designated and inserted in notice
hereinafter mentioned. See Rule 5.
For the purpose of enforcing and properly under-
standing the above code of signals, the following rules
are hereby established :
Rule 1. In giving signals make strokes on bell at
regular intervals. The bar [ — ] must take the same
time as for one stroke of the bell, and no more. If
timber, tools, the foreman, bucket or cage are
wanted to stop at any level in the mine, signal, by
number of strokes on the bell, the number of the level
first before giving the signal for timber, tools, etc.
Time between signals to be double bars [ ]. Ex-
amples :
6 5, would mean to stop at sixth level with
tools.
4 1 — 1 — 1 1, would mean stop at fourth
level, man on, hoist.
2 1 — 4, would mean stop at second level with
foreman.
Rule 2. No person must get off or on the bucket
or cage while the same is in motion. When men are
to be hoisted, give the signal for men. Men must
then get on the bucket or cage, then give the signal
to hoist. Bell cord must be in reach of man on the
bucket or cage at station.
Rule 3. After signal " Ready to shoot in shaft,"
engineer must give the signal when he is ready to
hoist. Miners must then give the signal of ' ' Men to
be hoisted," then "spit fuse," get into the bucket,
and give the signal to hoist.
Rule 4. All timber, tools, etc., " longer than the
depth of the bucket," to be hoisted or lowered, must
be securely lashed at the upper end to the cable.
Miners must know they will ride up or down the shaft
without catching on rocks or timbers and being
thrown out.
Rule 5. The foreman will see that one printed
sheet of these signals and rules for each level and one
for the engine room are attached to a board not less
than 12 inches wide by 36 inches long, and securely
fasten the board up where signals can be easily read
at the places above stated.
Rule 6. The above signals and rules must be
obeyed. Any violation will be sufficient grounds for
discharging the party or parties so doing. No per-
son, company, corporation or individuals operating
any mine within the State of California shall be re-
sponsible for accidents that may happen to men dis-
obeying the above rules and signals. Said notice and
rules shall be signed by the person or superintendent
having charge of the mine, who shall designate the
name of the corporation or owner of the mine.
Section 3 of the law says : " Any person or com-
pany failing to carry out any of the provisions of this
Act shall be responsible for all damages arising to or
incurred by any person working in said mine during
the time of such failure."
MONTANA STATE CODE OF MINE SIGNALS.

ring station signal and do not answer back.
2 — 1 — 2 bells are rung, engineer or station tender
does not understand, repeat signal.
In case of danger or accident, ring station signal,
station tender will reply 1 bell, ring 9 bells.
One copy of this code should be posted on the gal-
lows-frame and one before the engineer.
To be in effect from and after June 1, 1895.
This code is subject to change under certain condi-
tions.
The California code is furnished by the Mining and
Scientific Press, on cloth to withstand dampness,
printed in heavy black letters, with blank room for
the several levels. The size is 18x43 inches. The
Montana code can be had on application to Mine In-
spector Shoemaker, Butte, Montana.
Modern Boiler Making.
During the last twenty years the boiler shop has
undergone a change, the magnitude of which is
paralleled only by that in the machine shop. But
while the latter has been mainly brought about by
the introduction of new and improved machine tools,
the former is due chiefly to the development of a new
material — steel. But for this, the old methods which
were applicable to wrought iron would probably not
have been altered much even at the present time.
There are many points in common between the
machine shop of to-day and that of twenty or thirty
years ago, but there are scarcely any between the
boiler shops of the two periods. Twenty or twenty-
five years ago few firms were making steel boilers;
to-day the construction of new iron boilers is be-
coming exceptional. With the new material nearly
every machine used, nearly every shop method
adopted, nearly every detail of the work has been
altered or modified in a greater or less degree. Hand
work, too, is practically extinguished in the most
modern shops. Formerly there was a good deal of
flanging, bending, hammering, chipping, welding,
riveting, drifting and tapping done by hand, as there
is still in small establishments; but good boiler work
is now almost entirely a matter for machine tools,
and the importance of these, therefore, has grown
to an immense extent. A high-class modern boiler is
now machine made almost entirely from beginning to
finish. Since the errors of hand work are thus
eliminated, two boilers made to the same standard
are exactly alike.
Boiler making, to be carried on according to the
best modern methods, requires a very large plant, so
large that many a good-sized shop cannot afford it
all. With only a moderate amount of machinery good
work can be done, but it has to be done in a more
roundabout way, with considerable increase in cost,
which, as in other departments, sorely handicaps
such firms in competition with the big shops.
At the present time there are four power agencies
in use in boiler shops. Steam and water vastly
predominate; nearly all the heavy machinery is driven
by these agents. Air is chiefly used for operating
small tools, such as drills and calking hammers, while
electricity is employed for the same purpose, and,
but moderately as yet, for driving heavy machinery
tools. Steam, water and air are each suitable for
riveting, though the first has been largely displaced
by the last. Water power is adopted for heavy
flanging, shearing and punching ; steam is employed
for bending rolls, drills, and most of the machine tools
used for cutting purposes. Any large modern boiler
shop, therefore, must needs be in possession of at
least three power plants — steam, water and air — to
which it may be desirable to add the electric motor.
The applications of compressed air are growing at a
phenomenal rate, being applicable to all the small
portable tools used in boiler work. In large shops,
in which numerous machines are widely scattered,
any agency seems better than shafting and belting,
and before long one may anticipate that the extension
of the uses of air for small tools will be paralleled by
that of electric driving for heavy tools, in place of
belts and independent engines.
Lithographic Stone.
To the Editor:— About 20 miles northeast of here
has been discovered a ledge of lithographic stone in
4-inch layers. A company will organize to work it.
It is of some interest to note that Solnhofen, Bavaria,
now furnishes nearly all the supply of such stone.
Litho stones are found in France, near Montpelier,
but are not so good as the Solnhofen stone. Litho-
graphic stone is a compact and homogeneous lime-
stone. The Solnhofen stones cover an area of about
ten acres. The Santa Barbara deposit is 60 feet
wide and has been traced 5 miles. Litho stones must
be of excellent quality in order to satisfy the require-
ments of the art. Many stones found at Solnhofen
are laid aside as not coming up to the standard.
These are sold to builders and are used for paving
floors. A scarcity of superior lithographic stones, if
it should ever arise, would have the effect of bring-
ing into the market inferior stones. It is interesting
to note that the stones in Solnhofen do not lie deep in
the ground ; in fact, only the earth and some rock
have to be removed, as a rule. The stones lie in lay-
ers and have simply to be taken carefully from the
earth. The bulk of the ground beneath which the
Solnhofen litho stones lie belongs to the public, and
each homestead owner has a share in the ground.
From time to time the community measures out'a
new stretch of ground and divides it into lots, and
each gets his part. He can either explore the ground
himself or sell his claim to one of the large owners.
The ground itself, after it has been deprived of its
costly treasure, becomes again the property of the
community. Blue or gray lithographic stones are
the most costly ones, as they are harder and better
for use and more copies can be obtained from them.
Being harder, they stand the polishing on both sides
better than the yellow ones, and therefore are chiefly
used for exportation to the United States. In fact,
the United States takes only these double-faced
stones, which can be worked by the printer from
both sides. The Germans, on the other hand, are
wont to use single-faced stones. Every stone does
not take polish on both sides. A stone may be good
on one side, while on the other it is unfit for use — has
flaws, splits, etc. Such blemishes are not always
apparent on the surface, but may come on when the
stone is worked upon by the printer. It requires,
therefore, skilled workmen who have been in the
trade from their childhood to see that none but good
stones leave their hands. J. S. P.
Santa Barbara, Cal., Sept. 5.
Two Kinds of Brittleness.
Two kinds of brittleness ought to be discriminated :
1. "Primary brittleness," as, for instance, that ex-
hibited by gold when alloyed with lead, with arsenic,
or with bismuth. In such cases brittleness is charac-
teristic of the alloy from the moment of solidification.
2. " Secondary brittleness," a subsequent and more
gradual phenomenon, as, for instance, that exhibited
by certain varieties of German silver months or even
years after solidification. " Primary brittleness " is
an accident of birth; "secondary brittleness " is a dis-
ease that develops with age and circumstance. De-
teriorated German silver, or platinoid, when exam-
ined under the microscope, is seen to contain crevices
and fissures ; the section has patches of various col-
ors, corresponding, most probably, to separate masses
of "liquated" metal. It is further suggested that
by the process of "liquation " homogeneity of structure
is lost ; consequently the tensile strength of the ma-
terial varies prom point to point of its mass; so also
does the electrical conductivity. In passing after-
ward through the die of the wire maker, the weaker
constituents give way ; thus incipient crevices are
formed, and through these capillary channels moist-
ure subsequently intrudes. If such wires are used for
electric currents, maximum heating occurs at the
weakened sections ; this accounts for the failure of
German silver resistance coils on arc lights and other
circuits. The separate masses of dissimilar metals
constitute local circuits of very small resistance, and
within these circuits internal currents act de-
structively upon the alloys.
Cable for Bering Sea.
On the steamer Orizaba, heading northward, is a
submarine cable to connect Unalaklik, St. Michaels
and Nome City. It is 187 miles long — the longest sub-
marine cable ever to be laid by an American firm ; the
largest cable on the Pacific coast. Owing to the danger
of the cable being affected by the cold water and ice it
has been doubly armored. It is a single conductor Ker-
ite submarine cable, has withstood 3000 volts of elec-
tricity and a pressure of 800 megonnes. The cable
has a tensile strength of 5000 pounds. The main
cable weighs 2800 pounds per mile ; the shore ends
weigh 9000 pounds to the mile. The main cable is |
inch diameter, the shore ends 1» inches.
The steamer goes to Unalaklik, where the first bit
of cable will be laid. The cable will then be extended
to St. Michaels, 55 miles ; then direct to Nome City,
132 miles. It is expected that by the time the cable
is ready for use the overland line to Unalaklik will be
completed.

SONOMA COUNTY'.
(Special Correspondence). — The Great
Eastern Q. M. Co. has been operating
continuously since 1872. Its mine is 3
miles from Guerneville, the nearest rail-
road town, on a branch of the California
Northwestern Railroad. At present ore
is being taken from the Mount Jackson,
which is an extension of the Great Eastern
ledge. The latter company has a lease of
the Mount Jackson. The ledge has a
width of 80 to 175 feet, and dips at an
angle of 60°. The ore contains not more
than } of 1% of quicksilver. By reason of
economical arrangements in handling and
in reduction, as well as for fuel, this is
made to pay. The plant consists of a
regulation single-drum hoist, an air com-
pressor to propel power drills in the mine,
and necessary steam boilers. The fur-
naces are below the hoisting works. Wood
is the fuel used. The shaft is 500 feet in
depth (perpendicular), with an 80-foot
winze. Thence a drift 400 feet in length
taps the ledge. The mine produces 1200
tons of ore per year. This is a close cor-
poration, with Alfred Abbey, one of the
three owners, as Supt. The mine gives
employment to sixty miners and work-
men, besides fifteen woodchoppers.
A ledge of graphite is being developed
on the ranch of G. R. Skinner, 4 miles

ledge has been known for several years,
but not until now has there been any sys-

value. The Sorrento Coal M. Co., H. G.
Williams vice-president, is advancing the
capital necessary for present operations.
The shaft is down about 100 feet, where a
crosscut shows a well defined 7-foot ledge.

OURAY COUNTY.
(Special Correspondence). — The Mono &
Baltic mine, near Ironton, lies on the
western slope of one spur of Red moun-
tain, and has been developed to the pro-
ducing stage by Chas. Newman of Du-
rango. The property is opened through
a main tunnel, which trends eastward 600
feet, cutting through and beneath a large
ore body, comprising pyritic and oxidized
iron and copper ores, carrying copper,
gold, silver and a small amount of lead,
the iron and copper constituting a desir-
able fluxing material for smelters. The
ore lies between porphyry and lime, and
in the 1700 feet of work on the property
the ore is shown to be 100 to 125 feet wide
in many places. Host of lire development
is above tho tunnel, where an incline drift
follows the contact, considerable stoping
having been done. Some twenty-two cars
of this ore were shipped to the Durango
smelter last July. The Brooklyn, also a
part of this group, is well opened up, dis-
closing a bedding deposit of ore similar- to
that of the Mono.
The old Saratoga mine and mill, which
ran on a large scale ten years ago, is being
worked in a small way and may be ex-
pected to become a good producer again
as conditions become more favorable.
Ironton, Sept. 5,
(Special Correspondence).— The Ameri-
can-Nettie mill is 900 feet lower elevation
than the mine, being situated on tho Un-
compahgro river, a mile below Ouray.
Ore is transported from the mine to mill
over a wire rope tram line, 2000 feot long,
one span from tower to mill terminal be-
ing 1800 feet in length, swinging the ore
buckets 900 feet above the valley. The
mill terminal is 60 feet above tho vanner
floor. The ore passes through a crusher,
thence to the stamps, of which there are
twenty, the battery product passing over
amalgam plates and then to Wilfley tables.
The concentrates are dried on a platform,
resting upon coils of steam pipes, which
eonnoct with the boiler. The mill crushes
about seventy-five tons per day and is at
present operating on an old ore dump at
the mine. This mill, in its main parts,
was moved from Gunnison county.
Ouray, Sept. 6.
(Special Correspondence). — The Treas-
ury tunnel, locally known as the Ham-
mond tunnel, starts at Yankee Girl lake
and takes a westerly course, almost paral-
lel to that of the Meldrum. It has been
driven about 1800 feet and will be con-
tinued till it cuts under a group of claims
which the tunnel owners have under bond
and lease. A company of Pennsylvania
parties are principally interested.
The Bobtail, up the gulch, north of the
Treasury, is being further developed.
This is an old property, having a 3500-foot
tunnel, which was driven in 1892. The
ores are a pyritic iron, carrying some gold,
and some shipments are being made.
J. H. Ryan has a lease on the National
Bell dump, which contains thousands of
tons of material. He is sorting out the
better grade for shipment.
The Vanderbilt, Yankee Girl, Robin-
son and Guston are among the big prop-
erties which in former years made a great
record for Red Mountain, and which are
likely to be revived again. In fact, there
is more work now in progress on Red
mountain than has been seen for several
years. With the building of matte,
pyritic smelters— one at Silverton the
other at Ouray — Red Mountain ought to
find ready market for all the low grade
iron and copper ore that can be mined.
As has been noted, the Silverton smelter
is almost completed and one for Ouray
seems assured. Upon the success and
good management of these smelters de-
pend the revival and rapid development
of mining at Red Mountain.
Red Mountain, Sept. 5.
SAN JUAN COUNTY.
(Special Correspondence). — The Gold
King Con. M. Co.'s holdings now include
the original Gold King group, the Samp-
son group, the American and Anglo-
Saxon, all contiguous, mostly on Bonita
mountain, sloping to Cement creek, where
the company's mill is located at Glad-
stone. At the main workings, at an alti-
tude of about 11,000 feet, a tunnel goes in
531 feet to a hoisting station. From this
point there is about one mile of drifts and
crosscuts on the Gold King and Sampson
ore body, besides a great deal of stoping;
and from the same station a double-
compartment shaft sinks 107 feet to the
second level, where there are some 1600
feet of drifting on the Davis vein and on
branches therefrom. The veins, as a rule,
are not far from vertical, though in some
places there are vast ore bodies in nearly
horizontal position. The veins, both ver-
tical and flat, range in thickness from 15
to 40 feet, usually between well-defined
walls. The small size of the dump and
the small amount of waste underground
show very little material between walls
that is not pay ore, which is composed of
an iron, copper and lead sulphide, with
a considerable amount of white quartz.
The values are largely gold, with some
silver and lead.
A tunnel is being driven from the
American mine toward the Gold King,
which is designed to cut the latter vein at
600 feet below the hoisting station and
2000 feet from the entrance, the work al-
ready having proceeded 1300 feet. The
present working shaft will be sunk to con-
nect with the American tunnel.
A Bleichert wire rope tramway, 5320
feet long, carries the ore from the mine to
the mill, the line carrying forty-seven
buckets, each of 800 pounds capacity. One

span is 2240 feet between towers, spanning
the gulch between Lost and Bonita moun-
tains.
At the Gold King mill a new tunnel has
been started toward the Gold King and
Sampson group, which is 7x9 feet in the
clear, and is now in 600 feet. This will cut
the Gold King grounds at 1800 feet below
the surface and will he one mile in length.
The Gold King mill runs steadily, with
forty rapid-drop stamps and nineteen
vanners, milling about 120 tons of ore per
day. An extension to the mill has been
made for forty additional stamps and
twenty more tables, thus doubling the
present capacity. The machinery for the
new work is being put in place. About
10% of the saving is made on the plates,
the balance in concentrates, there being a
reduction of about five tons of ore to one
ton of concentrates. The vanners are
graded by speed — those taking the heavy
material running at 200 revolutions, those
receiving the middle size making 190 and
those taking the finest or more slimy por-
tion running at 180 involutions per minute.
Since last year a 250 H. P. Westinghouse
compound, upright steam engine has been
put in to operate the mill, also a new
twelve-drill compressor, which will soon
be brought into use in the two tunnels.
The steam power is supplied by four boilers
and three more are to be added. A new
tramway line is being erected to connect
the American tunnel workings with the
mill. This company owns and operates
the Silverton & Gladstone Railroad, com-
prising a line 9 miles long between the two
points named. Besides handling the busi-
ness of the company's mine and mill, the
road has a growing freight and passenger
business and is of great benefit to the Ce-
ment Creek district, where there is rapid
development.
J. C. Purpus and Williams have a bond
and lease on the Queen Anne group, on
the south slope of Brown mountain, which
they are developing. They also have a
lease on the Red & Bonita mill, near Glad-
stone.
Gladstone, Aug. 30.
(Special Correspondence). — The matte
smelting plant of the Kendrick & Gelder
S. & M. Co. is nearing completion, and it
is calculated to be in operation before the
first of November. The buildings, includ-
ing ore bins and assay office, are com-
pleted, the machinery is on the ground
and is being put in place. There are sev-
enteen ore bins completed for the various
assortments of ores. Trackage from the
Silverton & Gladstone Railroad is laid be-
side the ore bins. A flume, 5000 feet long,
takes 20 cubic feet of water per second
from Cement creek, which is delivered to
an impulse water wheel at the mill, under
170 feet pressure, producing 340 H. P.
This wheel will supply power to the crush-
ers and rolls in the sampling department,
to the blower for the furnace, and an elec-
tric generator for light. The furnace size
is 42x120 inches, has a capacity of 200
tons per day, and will be run in connection
with a Bretherton hot-air furnace, the
blast being supplied by a Connellsville
blower. From the furnace discharge the
slag will pass automatically through the
granulating laundry, thence into the
waste deposit, without the use of slag cars.
The furnace charge will be so mixed as
to run at least 3% copper; to contain
about 3% coke ana a small percentage of
lime, and Supt. E. W. Walter figures on
producing a 50% copper matte. The basis
of the operation seems to be to oxidize the
iron in the pyritic ore, thereby producing
heat and producing a concentration of
material of about sixteen tons to one ton.
The iron, by oxidization, passes out
through the slag. The work of the
Bretherton hot-air furnace is to take up
the waste heat which radiates through a
sei-ies of pipes in the drum and return it
to the furnace.
F. C. Kendrick, general Supt. of mine
and smelter, states that the Henrietta
mine, in Prospect basin, which belongs to
the company, is developed by three tun-
nels, which run in on the trend of the
vein 140 feet, 500 feet and 860 feet, respect-
ively, a 160-foot upraise connecting the
lower with the center tunnel, the latter
being connected with the upper by an
80-foot upraise. The vein stands nearly
vertical and is of good width. The
ore is sulphide of copper and iron, running
about 8% copper and ten ounces to twenty
ounces silver. There is considerable ton-
nage of ore now ready for the smelter. At
a point lower down the hill a tunnel site
has been located and a tunnel from this
point to cut 600 feet lower than present
lowest workings is contemplated. The
Henrietta is up Cement creek, is reached
by good wagon road 2 miles from the rail-
road. Plans have been partially made for
a 5500-foot tramway from mine to railroad.
Silverton, Aug. 31. Wascott.
Special Correspondence). — The Tom
Moore, up Animas river and above
Eureka, is being developed by tunnel
drift, which is cutting under the old
workings at considerable depth. It is now
in 1000 feet. A 1-mile pipe line is being
put in for water power.
The new Sunnyside mill started up a
month ago with twenty 1000-pound, rapid-
drop stamps, five Bartlett and four Wilfley
tables and three canvas tables. This is a
well constructed mill, operated by water
power, and is situated at Eureka. It is
crushing sixty tons per day of very hard
quartzite, whose values are chiefly gold,
which is saved largely by amalgamation.
In the concentrates a product containing
some lead and zinc sulphide is obtained.
Mr. Terry states that twenty more stamps,
with additional tables, may be added to
this mill. The old mill, situated a mile or
more up Eureka gulch, is operating on
about thirty tons of ore per day, having
fifteen stamps, with plates, the tailings
passing over Bartlett and Wilfley tables.
The Sunnyside mine is at the head of
Eureka gulch, at 12,500 feet altitude, the
ore being transported down to the mills
over a Finlayson tramway line 16,000 feet
long, operated in two sections — the first,
8800 feet long from the mine to the old
mill, and the second 7200 feet, from the
latter to the new mill.
The Scotia group, under lease to More-
land & Van Diest, is located up Picayune
gulch, at 12,500 feet altitude, about 1 mile
east of the Sunnyside. It comprises two
lode claims and a placer location. Present
development consists of one 300-foot tun-
nel, from which is a 200-foot drift on the
main vein ; and a crosscut from that 40
feet to the footwall. Two levels have also
been run at higher points. The main vein
is said to be 40 feet to 60 feet wide, adja-
cent to a porphyry footwall ; a feeder vein
runs at right angles to this. From these
veins two grades of ore are found, the
first class carrying free gold, which runs
from $10 to $40 per pound of ore, the sec-
ond class running from two ounces to five
ounces gold per ton of ore. It is consid-
ered a remarkable showing of free gold.

and from that level a second shaft is in 268
feet; the mine is worked without timber-
ing; the chambers are supported by pil-
lars and show no sign of caving. The av-
erage amount of ore extracted daily is sixty
tons. This is crushed, concentrated in the
mill, hauled to Durango and sold to the
ore buying firms. From that point it is
shipped to a smelter and reduced to bul-
lion. The Cornish pump lifts enough
water for crushing purposes. The San
Marcas mine is within 500 yards of the
Las Vacas, has no veins or leads; it is a
solid block of ore. H. W. Collins is Supt. ;
W. J. Grace, general manager.
THE KLONDIKE.
The Dawson Board of Trade has de-
cided to reduce the value of commercial
dust in circulation in that town from $16
to $15 per ounce. The action is inspired
by the adulteration of the dust with black
sand. Sept. 15th is the date set for the
reduced valuation to go into effect.
Books Received.
"Municipal Improvements," W. P.
Goodhue. This is a manual of the meth-
ods, utility and cost of public improve-
ment for municipal officers, a sensible,
practical treatiso which would be of value
to any city officer honestly interested in
good city government, but would be
laughed at by the peanut politicians who
usually run municipal affairs. Its sale
might be in direct proportion to the num-
ber of city officials in the country who
really want to have good sewers, streets,
etc. Published by Jno. Wiley & Sons,

" List of Data Required for the Proper
Designing of Railroad Bridges and Tres-
tles, " is the long name of a little pamphlet
published by Waddell & Herrick, Kansas
City, Mo. What it lacks in volume is
made up in condensed suggestion, and any
one considering such structure would find
many points in the data furnished that
would be of economic value. There is no
advertising about it, it seeming to be a
pro bono publico proposition. The firm
will send a copy free anywhere upon re-
quest.

R. U. Goode of the U. S. Geological
Survey has gone from Bingham, Utah, to

the field of economic geology which is now

Goode tells tho S. L. Tribune that it is
more extensive than at any period in
many years. Already the regions in what
is now commonly known as Nome are un-
der survey, the corps which has been as-
signed to it constituting one of the strong-
est that has evor been in the Geld. All
this activity on the part of Uncle Sam en-
courages the belief that he will yet con-
sent to the creation of a "bureau" of
mining, if not a distinct "department,"
for at no timo has mining been pursued
by so many persons, or when so many
were equipping themselves to intelligently
engage in it. That such a department
should exist has long been urged by those
associated with the U. S. Geological Sur-
vey, but, as suggested by Mr. Goode,
"about 1% of the country's multifarious
recommendations never get further than
the congressional committee to which
they are referred, and that relating to a
department of mining has experienced no
different fate up to the present."

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co. 's SCIEN-
TIFIC Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Box Printing Machine.— No. 656,-
383. Aug. 21, 1900. John F. Ames, Port-
land, Or. This invention is designed to pro-
vide for the printing of the boards which
are employed for making wooden boxes.
These boards are not very carefully sawed
and therefore vary in thickness, and it is
necessary to so mount the printing rollers
that they will adjust themselves to the
varying thicknesses of material. The rol-
ler carrying the type of printing surface
and the second roller have the ends
journaled and turnable in independent
and elastic bearings so that they are mov-
able to and from each other, and one end
is capable of a vertical hold independent
of the other to compensate for different
th icknesses of the ends of the board caused
by irregularities in sawing. Means are
devised for intermittently passing the
boards to be printed between the rollers,
and means for transmitting power to
rotate the rollers in unison. By an ar-
rangement of driving and idler pulleys and
a rope or belt passing around them the
automatic adjustment of the rollers is per-
mitted without deleterious effect upon the
belt.
Harness Support. — No. 656,405.
Aug. 21, 1900. William R. Hewitt, San
Francisco, Cal. This invention is designed
for suspending harnesses in a spread con-
dition as they are employed in fire, police
departments and like places where it is
necessary for the horses to be attached to
the apparatus and in readiness to start
in the shortest space of time after an
alarm. These harnesses are usually
spread out and suspended by ropes or
equivalent attachments, but the devices
by which they are thus held are not of
permanent adjustment and are continually
in need of repairs. In the invention is em-
ployed a series of telescoping tubes, with
springs in the tubes whereby each of the
set is independently spring supported.
Devices are employed by which the
springs may be compressed and shortened
when a weight is hung from the device,
and are extended and act to shorten and
telescope the tube when relieved of the
weight so that the tubes are carried to the
upper part of the room and out of reach
as soon as relieved of the harness. In con-
junction with the springs may also be used
pistons movable with the tubes so as to
compress the air and to regulate the
movement of the tubes when they are re-
lieved of the weight of the harness so that
they do not fly up too suddenly.
Hydraulic Riveting Apparatus. —
No. 656,815. Aug. 28, 1900. S. Foreman,
Sacramento, Cal., assignor to Schaw,
Ingram, Batcher & Co., same place. This
invention is designed [or riveting the
longitudinal seams of seotions or joii
called from which lengths of pipe are
afterwards made up by riveting those sec-
tions together. It consists of a mechanism
by which tho overlapping edgos of the
plates are pressed together just previous
to the heading of the civet, a mechanism
by which the section is advanced a dis-
tance equal to that between the rivet
holes, means for automatically adjusting
the same and means for reversing the
movement of the feed apparatus so that
ono lino of rivets is placed and headed
through tho length of the section and the
apparatus then returns the pipe and the
other line of rivets is fixed and headed.
Means are provided for varying the feed
and spacing to suit tho difference between
the rivet holos of different classes of pipe
and improved construction of the riveting
heads. The whole is dosigned to effect a
perfoct closure of the overlapping edges
of the pipe before the rivet is headed so
that loaky joints are prevented.
Hydraulic Plate Closing and
Riveting Device.— No. 656,801. Aug. 28
1000. J. H. Batcher, Sacramento, Cal., as-
signor to Schaw, Ingram, Batcher & Co.,
same place. This invontion relates to an
apparatus which is dosigned for riveting
pipe sections together to form convenient
lengths for transportation and subsequent
use. It consists of a ram and its cylinder
with pipes by which iluid under pressure
is admitted thereto, a mandrel and a rivet
head-forming tool opposed to the ram, a
sleeve loosely surrounding the rivet head-
ing tool, hydraulic pressure plungers and
a head transversely connecting the upper
end thereof and supporting the sleeve, and
by which said sleeve is forced upwardly to
form a support for the meeting pipe sec-
tions whereby the pressure of the ram
first closes the sections together, and
afterwards forces the support backwardly
to allow the rivet to be headed. Water is
brought to the ram cylinder and plate
closing pressure cylinders by means of a
swivel jointed pipe from an accumulator
or pressure apparatus, and is distributed
to the respective parts through suitable
branches. The whole apparatus may be
suspended or supported from a traveling
carriage so that the apparatus may be
moved alternately to two different parallel
lines of pipe; and when one joint has been
completed, the other line of pipe being in
position, the apparatus can be shifted to
the new line while another joint is being
prepared from the first named line. Suit-
able carriages support and carry away the
finished sections.
Baling Presses.— No. 656,767. Aug.
28, 1900. Charles Dodge, Davisville, Cal.
This invention relates to improvements in
baling presses of that class in which the
follower moves in a vertically disposed box
or chamber, and in which a door has its
lower edge hinged near the bottom so
that the top may drop outwardly to re-
ceive the charge of material, said door be-
ing closed when the press chamber is suf-
ficiently tilled and previous to raising the
follower to compress the bale. The in-
vention consists of a combination of levers
operating similarly to what are known as
carriage joints and connections, and by
these levers the door is opened and closed.
The levers are in turn connected by chains
with the operating sweep which may be
driven by horse or other power.

have demonstrated
as valuable in this
class of machinery.
The brakes, clutches and reversing gear are arranged to be operated by compressed air or steam, by means of auxiliary cylinders
which are under full control of the engineer, stationed upon the elevated platform shown, insuring the most rapid work with absolute
safety. Shaft hollow forged steel of ample strength and stiffness to withstand any strains; reciprocating parts of steel and are as light
as consistent with the duty required; cylinders of the " overhung " type, weight being taken by a guide saddle, which admits of free
longitudinal movement, due to expansion, causing no strain on bed plate or foundations; cylinders steam-jacketed, fitted with valves
provided with Corliss releasing gear and hand cut-off, enabling the engines to be run economically with reference to the work to be
performed; bed plates modification of the Porter Allen type, heavy and substantial, with large foundation base and anchor bolts. A
duplicate of this engine has also been furnished the Homestake Mining Company of Dakota.

XHE GRIFFIN
THREE ROLLER
MI
The Griffin Three Roller Oro Mill is a simply constructed Mill, suitable for working all kinds of ores that
requiro uniformly fine crushing by the wet process. This Mill is a modification of the well-known Chilian
Mill, but the rollers run upon a crushing ring or dio, which is inclined inwardly at an angle of about 30 degrees,
the rollors thomsolves also being inclined to the central shaft of the Mill, thus utilizing the centrifugal force,
as well as tbo weight of the rollers themselves as a crushing agont. The Griffin Three Roller Ore Mill is there-
fore a Mill of groat strength, and has few wearing parts. Wo construct these Mills with extreme care, using
only the best of raw materials, which aro most carefully worked by men who are specialists as mill builders.
We sell the Griffin Oro Mill on its determined merits, and will gladly supply full information regarding it to
I any one.

The Ideal Conveyor Belt
Is the one that will carry stone, ore, coal, wet or dry
material, holding buckets firmly and securely; will
stand all kinds of exposure, and resist the heaviest
strains during a long period of service. This is what
the LEVIATHAU BELT has done, and we quote the
following from a letter from the New York Steam Co. :
"We have used Leviathan Belting for four years, up
to 24-inch by 8-ply, elevating and conveying coal. Some
of the Belting is outside, exposed to freezing weather;
some in a steam bath. In both conditions the results
have been very gratifying, over 500 tons having been
handled in ten hours time."

can stand in an upright
natural position. It is
just the washer for the
poor man who has not
the money to put in ex-
pensive machinery. It
will do the work of ten
men with gold pans. It
is just the washer for

CROWN GOLD MILLING CO
Manufacturers of the "CROWN" CONCENTRATOR and CROWN
ORE SIZER. A dry process of sizing and concentrating ore, sand or
gravel. Designed to accord fully with the laws of specific gravity,
and especially adapted to refractory ore or localities where there is
no water.
The chief claims for the Crown Concentrator are that it occupies
less floor space and has nearly four times the capacity of any wet
concentrator; that it will concentrate ores containing base and refrac-
tory metals that ordinarily slime and carry off values; that it effects
a saving of values far above the ordinary methods of concentration.

A Big Copper
Furnace.
At no period in
the history of the
world has the de-
mand for copper
been so great as
at the present
time, and the ap-
pliances for its re-
duction are being
steadily improved.
On this page ap-
pears an illustra-
tion of the Mitchell
economic hot blast
water jacket fur-
nace, recently
built by the Union
Iron Works for the
Copper Queen
Consolidated Min-
Company of Ari-
zona. This struc-
ture, standing 50
feet in height, is
foremost among
the largest and
most improved
furnaces ever
built, having a ca-
pacity of 300 tons
per day. The main
feature of this fur-
nace consists in its
a d a p t a bility for
reducing, at one
operation, raw
copper sulphide
ores to a matte
suitable for besse-
merizing, without
preliminary roast-
ing. The blast is
first introduced
into air jackets lo-
cated above the
smelting zone, and
is heated to a tem-
perature varying
from 500° to 900°
F., and is then in-
troduced into the
furnace through
tuyeres as shown.
The cond e n s i n g
chamber, located
on top of the air
jackets, collects
most of the fine
dust, which is
run out through
suitable openings,
bricked and re-
turned with the
charge to the fur-
nace. The makers
say that this fur-
nace, by means of
the hot blast and
special features
HOT BLAST fflATER JACKET FURNACE.
introduced, af-
fords the nearest
approach to py-
ritic smelting
that has been per-
formed with suc-
cess, the fuel used
being about 3% of
the charge, which
marks an advance
in the economy of
smelting.
The inventor of
this fm-nace, Mr.
George Mitchell,
is a progressive
metallurgist, hav-
ing given a life
study to the smelt-
ing and refining of
copper.
The works re-
ferred to are now
building furnaces
of this type, of 200
tons daily capac-
ity, for the Greene
Consolidated Cop-
per Company and
also the Copete
Copper Company,
together with all
accessories consti-
tuting complete
plants.

Stock Brokers'
Association has
decided to appoint
a "rustling" com-
mittee whose duty
it shall be "to in-
terview the busi-
ness men with the
view of inducing
them to subscribe
money to be in-
vested in mining
stocks" under the
direction of an-
other committee
which the brokers
will appoint, the
object of the
scheme being to
"strengthen the
stock market." It
is to be explained
to the business
men that the bro-
kers' committee
could spend the
money, if the busi-
ness men would
put it up, in buy-
ing such stocks as
were sure to ad-
vance and at
the same time

If eight persons should make eight distinct and
separate placer locations of twenty acres each, and
seven of the locators should convey their claims to
the other, it would require annual assessment work
of the value of $800 to maintain the possessory right
to all of the claims ; but in the case of a single location,
embracing 160 acres of placer mining land, the owner
thoreof, in order to maintain his possessory right
thereto, would not be required to expend $100 worth
of mining labor on each twenty acres thereof, but his
possessory right to the entire 160 acres might be
maintained by performing thereon $100 worth of
actual mining work, designed in good faith for the
improvement of the 160-acre location as a single min-
ing claim.
To Prof. S. B. Christy, Dean of the College of
Mining, University of California, this paper is in-
debted for opportunity to publish the valuable data
on the comparative value of coal and crude petroleum
as fuel, which appear in the issues of last Saturday
and to-day. The experiments, of which the published
article is the condensed result, cost nearly $1000 and
months of skilled effort. The article supplies the
latest published data of the kind. Since the early
part of 1898 this paper has published a number of
technical articles on the subject of petroleum in Cali-
fornia, and it is probably not too much to say that
the articles so published throughout 1898, 1899 and
1900 formed the basis for the present successful de-
velopment of California's oil wealth.
In depth from surface and magnitude of operations
Michigan is pre-eminent in American metal mining.
The Lake Superior region first produced copper in
1845, the product that year being 26,880 pounds,
worth $6000. Over half a century of mining and sci-
entific progress resulted last year in giving employ-
ment to 13,051 men in the mines of Houghton county,
the product being 146,950,338 pounds, worth $28,-
098,382. The total production of the Lake Superior
copper mines to the close of 1899 was 2,521,378,296
pounds refined copper, valued at $389,588,204. In
the last ten years the product and the number of
mine workers have nearly doubled. In 1890 there
were 7310 men employed in the mines of Houghton
county. It is estimated by the mine inspector that
14,000 men now find employment therein. The Hecla
paid its first dividend of $5 per share in December,
1869; the Calumet its first in August, 1870. In
thirty years the Calumet & Hecla has paid over
$70,000,000 in dividends.
Strike of Coal Miners.
The threatened strike in the Pennsylvania anthra-
cite coal mines has come to pass and 100,000 coal
miners are idle. The same conditions that caused
strikes there before occasion the present disagree-
ment, with probably the same result. J. Fahey,
president district No. 9, sends from Hazle ton, Pa.,
a statement in which he says :
The causes that have led the miners to make their
present demands have been stated generally, but not
in detail. Briefly, they are the manner in which the
men are overcharged for the necessaries of life at
the company stores, for their tools and powder, and
the exorbitant rent they are compelled to pay for
company houses ; the fact that at the present time
the ton of coal gotten out by a miner usually weighs
about 3500 pounds, and even with this great surplus
the fact that he is docked for slate and dirt ; the fact
that there is no uniformity of pay, and a score of
things that need not be spoken of here. The changes
that we ask for are few and all are not so great that
they might not be made. In regard to the stores,
food costs from 15% to 20% more than it should. An
ordinary celluloid collar button, the brand that sells
for 5 cents a dozen in a store, is sold by the company
for 5 cents each. From a collar button to a keg of
powder is about everything a miner needs. The
DuPon't powder works manufacture this powder and
sell it at 90 cents a keg. The companies charge the
miners $2.50 for this same powder. In the soft coal
mines and in other mines this powder is sold to miners
at $1.50 a keg, which gives the company a profit of
about half a dollar. The anthracite operators de-
mand a profit of $1.50 on every keg. They demand
the same amount of profit on all tools. We demand
that the price of powder be reduced to at least $1.50
a keg. We ask that the other necessities of life be
reduced equally. We seek lower rent. We also ask
that hereafter the coal mined shall be weighed and
that a ton shall be the same number of pounds as that
sold by the operators. We ask that the pay be uni-
form throughout the region. In some mines the
workmen get $1.25 a day for work that men get only
$1 for in other mines. This condition creates discon-
tent. We seek to have the same amount paid for
the same class of work in all mines. The miner
earns on an average about $1 a day, and the extra
cost of his food and other necessities means a lot
to him.
The employers and operators claim that the strike
is incited mainly for political effect, the same as the
Homestead strike in July, 1892, which many think
determined the result of the presidential election the
following November. Such a strike as the present
one always entails great loss, even though the strike
be short-lived, as strikes among coal miners usually
are. The chief element to be feared is the uncon-
trollable Hungarian and Pole contingent that so
quickly resorts to violence, riot and destruction of
property, of course resulting in calling out the militia
with the usual unfortunate termination.
Like every other class of workers, coal miners un-
doubtedly have their grievances, but, probably, the
operators and owners have their own troubles. If at
all practicable, it would seem better to have a con-
ference of employers and employes. Considerable of
the ill will and consequent disaster arises from lack
of knowledge of conditions, each side viewing matters
solely from its own point of view. The complaints
voiced above from the strikers' representative mani-
festly demand fair hearing and an attempt at adjust-
ment, and probably a sincere and well-meant effort
to secure mutual justice would avert the present
trouble, with its inevitable disastrous conclusion ; but
if, as the employers claim, the order to strike was
sent out almost simultaneously with such demand for
adjustment, that would give color to their assertion
that the whole thing is mainly and primarily intended
to influence votes next November — an assertion that
does not admit of present proof. The mine owners
allege that the interests of the bituminous coal oper-
ators favor the strike as a matter of business com-
petition.
The right of organized labor to strike is a natural
one, and in the State of Pennsylvania is made legal
by statute; and so long as the men are within their
rights, they naturally have strong claims upon public
sympathy. Such sympathy is, however, immediately
forfeited by injury on the part of the strikers to per-
sons or property, and in this respect the worst enemy
to the success of a strike is the lawless element,
whose violence constantly menaces the effort to se-
cure justice from employers.
Registers and Receivers of land offices are in
receipt of orders from Washington, D. C, instruct-
ing them to keep their offices open to the public for
business from 9 a. m. to 4 p. m. each day, except Sun-
days and holidays. The important part of the order
is as follows : ' ' No original business should be trans-
acted before 9 o'clock a. m. nor after 4 o'clock P. M."
It has b6en the custom in some localities to attempt
to use the Land Office in getting "snap judgment"
in filing entries, applications or adverses at hours
others than those officially designated, and with the
official order in plain view the local land officials can
now decline to transact business at any other time
than that officially prescribed.
Of General Application.
At a recent banquet to prominent visitors given by
mining men at Rossland, B. C, in the course of sev-
eral speeches many good things were said, among
the best being the following in the course of some re-
marks by E. B. Kirby, manager War Eagle and Cen-
ter Star mines :
In the progress of civilization no factor has ever
been known to exercise such a powerful influence as
mineral wealth in attracting energy and capital to a
country. * * * * Mining men realize that apart
from their selfish interest in the question, it is always
a matter of the wisest policy to do everything possi-
ble to encourage mining. Nature places enough
obstacles in the way, and it is surely the part of wise
government to remove them so far as possible, and to
encourage and aid in every way those who are devot-
ing their lives and fortunes to the work of developing
these resources. The interdependence of all citizens
in the mining districts is so great that they stand or
fall together according to the success or failure of
the work. It is the experience of the oldest mining
regions that every burden or restriction imposed
upon the mines invariably affects every one in the
community. For all these reasons mining men every-
where feel that they are justified in asking, in the
name of public welfare, for special considerations.
Mining is the basic industry of a nation. On it
rests as on an underlying foundation the prosperity
of a country, and when the industry is hampered, and
that which is necessarily difficult is made more so by
indifference or hostility, the result is injurious to all. I
A Denver, Colo., daily asserts that T. F. Walsh
will receive several million dollars for his Camp Bird
mine at Ouray, Colo. , from a syndicate of English and
American investors headed by A. Beit of South Af-
rica and J. P. Morgan of New York. The further
assertion is made that a draft covering the first
payment is now on deposit in a Denver bank,
that a mining expert is now at Ouray to make
a final examination of the mine on behalf of the
syndicate, and it is expected in Denver that the deal
would be closed by Oct. 1st. There has been consid-
erable attention of late given the rumored sale of the
Camp Bird property. About the 1st inst. a Mining
and Scientific Press staff correspondent was de-
tailed to visit the mine. The result of his visit is
published on page 347, being devoted largely to mill
practice.
The apex law, with its extralateral rights and all
the ills of litigation that follow in its train, is a leg-
acy of the old Spanish rule. It was a Spanish insti-
tution adopted when California was added to the
United States and perpetuated in our mining stat-
utes. All Spanish speaking countries discarded it on
attaining their independence, Bolivia alone excepted.
In the United States and Bolivia that ancient ruling
is still the supreme law, in defiance of the great
principle of common law observed by all the rest of
the world.
The U. S. transport Lawton is bringing back
stranded and penniless men from Cape Nome, lured
there by fairy tales told by transportation companies
and repeated by a venal press. The only punishment
to those who occasioned so much suffering and loss
must be the consciousness of their own identity. It
is fortunate for their dupes that the Government took
pity on them.
The payment of the current $20 dividend of the
Calumet & Hecla Mining Co. makes an aggregate of
dividends declared by the directors of that company
of $70,850,000, being a larger amount than has ever
been paid in an equal space of time to the stockhold-
ers of any gold or silver mine, and is exceeded only
by the amount of dividends paid by the Con. Cal. &
Va. of the Comstock, Nevada.

Electricity was first used in mining in Colorado in
1889 ; first used in mining in California at the Big Bend
mine, Feather river, in 1888.
A millsite may be patented by compliance with the
same requirements regarding survey and notice as are
applicable to mines or lodes.
Sinking was discontinued on the Comstock, Nevada,
March 28, 1882. The combination shaft of the C. & C.

Wave motors are interesting toys, but the present
state of the art is not encouraging to those desirous of

Ordinary amalgam from a hydraulic sluice box will
run about 65% quicksilver and 35% gold. In retorting
there would be an average loss of 10% of the quicksilver.
Asbestos and carbonate of magnesia are among the

" The first gold mine in the United States " is believed
to have been the Barringer, in Stanley Co., North Caro-
lina— a placer claim that later was developed into a pay-

Continued use of cyanide of potassium for remov-
ing the green copper oxide sometimes found on copper
amalgam plates will ultimately make them too hard for
the mercury to sufficiently adhere.
An ounce of standard gold in London, i. e., gold of
916.6 one-thousandths fine, is worth £3 17s 9Jd. An
ounce of fine gold in London, i. e., of 1000 fine, is worth
£4 4s lOd. An ounce of fine gold in New York is worth
$20.67, or £4 4s lOd.
One can always concisely explain what he thoroughly
understands, and in any event his explanation of it is
usually in proportion to his knowledge of the subject.
Indistinctness of expression is inevitable where there is
obscurity of thought.
If one wants to write a good book on mining and mill-
ing gold ore, a bunch of catalogues issued by mining ma-
chinery manufacturers and a file of this paper would fill
all requirements except the mechanical work of compila-
tion and writing a preface.
A rust joint that will stand heat and cold and rough
usage is made as follows: Mix ten parts of iron filings
and three parts of chloride of lime with water to a paste.
In twelve hours it will set so that the iron will break
sooner than the cement.
A drawback of the duties paid on imported lead re-
fined in a bonded establishment and subsequently with-
drawn on payment of duties for domestic consumption,
is allowed upon the exportation of the articles manu-
factured wholly from such lead.
Fossilized cedar tree trunks 3 feet in diameter have
been found in California drift mines at points over which
were 700 feet of lava, a few inches of the outside changed
to lignite, the remainder perfect in the grain and retain-
ing the pungent odor of the wood.
THERE is no "prospecting" east of the Missouri river
for two reasons — 1st, there isn't much to "prospect"
for, and, 2nd, as thore are no public lands, even if there
were anything to prospect for, the prospector would
have to get permission from the owner of the ground.
FOR a loose rubblo wall the height should never ex-
ceed 10 feet, and the base width should be at least one-
half the hoight. To get a well-proportioned wall of this
material the base can be three-fourths the height, with
a face having a half to one slope and a back with a one
to ono slope.
There are mines in Pitkin, Park and San Juan coun-
ties, Colorado, almost 14,000 feet above the level of the
sea, in limestone in connection with porphyry. There
are mines in California the lower workings of which are
nearly 1000 feet below the level of the sea, in slate,
quartz and granite.
Stone for building should not absorb moro than 5% of
water in twenty-four hours. It need3 to be insoluble. A
simple test for insolubility is to put some of the crushed
stone in a glass of water, let it alone for an hour, then
stir. The cloudier the water becomes the more soluble
material there is in the stone.
To temporarily stop small leaks in seams of boilers
or pipes, mix equal parts of air-slaked lime and fine sand
with finely powdered litharge, in parts equal to both the
lime and sand. Keep powder dry in a bottle or covered
box. When wanted, mix as much as needed to a paste
with boiled linseed oil and apply quickly, as it soon
hardens.
Sulphide of mercury may be found at Sulphur Bank,
Colusa Co., Cal., where also may be seen in decomposed
volcanic rocks fissures from which issue steam and hot
alkaline water, the sulphur springs depositing siliceous
sinter which contains cinnabar and sometimes gold, as do
Steamboat Springs, Nevada, where can be seen ore de-
posits in process of formation.
In the progress of practical mining our readers can
greatly aid by sending accounts of mining or metallurgi-
cal work, notices of what is done in the mine that is
deemed of sufficient value to merit publication, thus add-
ing to the stock of common knowledge. Where possible
the matter would be of added value if accompanied by
photographs or sketches for suitable illustration.
If the quicksilver flours in an arrastra grease may
have got into the basin, or the pulp may be too thick;
arsenic and black oxide of zinc tend to sicken quicksil-
ver. If it be so finely floured that the minute particles
will not unite, it can be collected by patient addition of a
little sodium. Where black oxide of manganese can be
shown to be the cause of flouring, a little quicksilver
added to the charge will help.
An explosive intermediate in power between nitro-
glycerine and ordinary blasting powder consists of a mix-
ture of the nitrates of sodium and potassium with sul-
phur, bichromate of potassium and coal tar. The latter
constituent renders the explosive impervious to damp
and holds the whole together. The proportions used
are : Sodium nitrate, 69 parts ; potassium nitrate, 5
parts ; sulphur, 10 parts ; potassium bichromate, 1 part ;
coal tar, 15 parts. After mixing the powder is com-
pressed between warm plates. Taking ordinary powder
as 1, the power of this explosive is 4.9 to 7, nitro-glycer-
ine being represented as 9.
The introduction of electric motor driving on ma-
chinery has led to such modifications in the design of
machinery as would naturally follow from the differences
between belting and motors. For example, since the
motor is small and can be built into the machine close to
the cutting tool, or the part which uses the power, all
shafts, gearing, wheels, etc., within the tool, which have
been heretofore necessary to receive the driving belt and
transmit its power to the tool, may be dispensed with,
and then the frame of the machine may be made a differ-
ent shape, or much lighter, since it does not have these
additional parts to support.
.It is not unusual for a man with a mining claim for
lease or sale to endeavor to get it in some line connecting
it with a well-known producer, on the theory that the
trend of the ore body is in that particular direction.
Nature never laid down these ore channels with such
mathematical exactitude. If anything, the ore shoots
follow the lines of least resistance, and these may be very
irregular. While it may be an aid in inducing capital to
invest in some enterprise to show a colored map with red
lines all leading to a famous producer, yet ore bodies can
and will be opened up without reference to any such
arbitrarily drawn lines.
Air in its passage through pipes is subject to friction
in the same manner as water or any other liquid. The
pressure at the compressor must be greater than at the
point of consumption in order to overcome the resistance
of the pipe. The power which is needed to produce the
extra pressure, representing the resistance of the pipe,
is lost, as there can be no useful return for it. The losses
by friction may be serious if the piping system be poorly
designed, and on the other hand extravagant expenditure
in pipe may result from a timid overrating of the evils of
friction. The difference in pressure between the en-
trance to the pipe and the point of use is, in hydraulic
engineering, termed the loss of head, and the power lost
— in hydraulics — is directly in the ratio which this loss of
head bears to the entire head. The same line of figuring
is sometimes applied to pneumatics. Friction of air in a
properly designed pipe system is not a serious matter,
and can be made as small as the most exacting require-
ments may demand. To reduce pipe friction the pipes'
must be enlarged, and, as this means additional expense,
it is advisable to have a careful plotting made of the en-
tiro plant to see what may be true economy.

ported $8,456,053 gold ; for the first seven months of 1900
New York city imported $1,884,761 gold; for the first
seven months of 1899 New York city imported $10,299,-
464 silver ; for the first seven months of 1900 New York
city imported $10,369,783 silver. For the first seven
months of 1899 New York city exported $25, 778,035 gold ;
for the first seven months of 1900 New York city ex-
ported $29,657,620 gold. For the corresponding periods
San Francisco imported respectively $10,828,228, $9,049,-
679 gold; $1,546,894, $1,725,025 silver; and exported
$2,808,249, $4,646,680 silver. These figures are furnished
by the Sub-Treasurers of the two cities.
The laws governing the flow of air in pipes are some-
what complex. For any given velocity the loss in head
due to friction, if stated as a per cent of the total head,
will not be affected by the pressure; but, as usually
stated, in pounds on a gauge, it becomes greater for the
same velocity in the pipe, as the pressure becomes
greater. The velocity varies approximately as the
square root of the loss of pressure. The loss is not
directly as the length, except for short distances and low
velocities. As a pipe is extended, the velocity of the flow
of air in the distant end of pipe becomes greater, by rea-
son of the increase in the volume of air at that point.
This increased velocity causes a greater loss of head for
each length of the distant pipe.
The durability of building stones is indicated by their
chemical composition, both in the crystalline and the
non-crystalline, or sedimentary groups. The nature of
both the grains and the cementing material is also to be
considered. The latter may be such as to be really
acted upon by atmospheric elements, and the stone fall to
pieces as a heap of quartzose sand, each grain of which,
by itself, would have resisted for ages. Without the
bond the tottering wall gives way. The principal atmos-
pheric agents which attack stones aro carbonic, hydro-
chloric, nitric and sulphuric acids, ammonia, and several
Organic acids. These agents, carried by rainwater, act
by solution, oxidation, deoxidation and hydration and
the constituent minerals, as well as the cement, are af-
fected by them. The durability of any given stone is
determined by that chemical constitution which is least
liable to change under their action.
Flat ropes are composed of a number of wire ropes
called " flat rope strands," of alternate right and left lay,
placed side by side, secured or sewed together with soft
Swedish iron or steel wire, forming a completed rope.
The sewing or filling wires, being softer than the steel
wires comprising the strands of the rope, act as a cush-
ion or soft bed for the strands, and wear out faster than
the harder wires composing the latter. When the sew-
ing wires are worn out the flat rope can be resewed with
new wire, and if any of the rope strands are also worn or
damaged these can be replaced with new portions. Flat
ropes are used principally for hoisting purposes. When
large and long ropes are used in hoisting heavy loads out
of deep shafts round ropes require large and heavy
drums on which to wind ; flat ropes, winding on them-
selves, need a reel very little wider than the width of the
rope. Flat ropes do not spin or twist in the shaft.
Osmium is one of the rare metals, the densest of all
metals and the most refractory, being infusible at any
except the highest attainable temperatures. It is found
native as an alloy in certain ores of platinum and iridium.
It is a hard, bluish-gray metal, with an atomic weight of
191.1 and specific gravity 22.477 — the heaviest substance
known. Its tetroxide has a strong odor of chlorine,
from which circumstance its name was originally derived.
It is suggested as the material of a new electrical fila-
ment because of its practical infusibility — its known re-
sistance to temperatures in which platinum and iridium
volatilize and disappear. The intensity of light emitted
by an incandescent substance increases rapidly with its
absolute temperature. By heating osmium in a vacuum
with an electrical current strong enough to volatilize
platinum, it attains a luminosity hitherto almost un-
known, emitting a white light of agreeable quality and
color, but of great intensity.
A drill sharpener says: "The most important
thing in tempering drills is to heat just the edge of the
drill as short as it is possible to do; for this reason : sup-
pose you heated it back, say, 2 inches from the end, and
tempered it in that way, the chances are at the first or
second blow the drill is struck off flies a piece of the face •
of the drill — sometimes 1 inch and at other times J-inch.
Then this has to be all cut up before you can go on.
I had this occur to me once when I was engaged at drill
sharpening. I worked at it for eighteen months, and in
the first week I had a piece drop off of the end about
1 inch. That gave me a sufficient lesson never to let it
occur again. Now, if you want to make a drill larger or
smaller than it was before, you have then to heat it just
as long as you want, and, as soon as made ready for tem-
pering, put it down to cool off, and when cold take it and
temper as I describe above. When a drill is put into
water it wants to remain until completely cooled off, he-
cause if you take it out not completely cooled it is liable
to fly off."

While coal was being used very careful working
tests were made continuously, one boiler being set
aside for this purpose. The amount of water enter-
ing the boiler was measured by a meter on the feed
pipe and the amount of coal burned was weighed.
Besides this, chemical analyses were made of every
kind of coal used. The following table gives some of
these :

*NOTE. — In justice to the Corral Hollow coal, it should
he stated that the coal first mined was from the surface
and was a quality inferior to that now put on the market.

Eckart gave an evaporation from and at 212° F. of 7.192

The Western Sugar Refinery has exceptional op-
portunity for getting cheap coal, and handling it
cheaply. It has its own wharf and bunkers, and from
the bunkers the coal drops to the fireroom by grav-
ity. The coal was always bought by the shipload and
thus very low rates were obtained. The price of coal
varies greatly from time to time and, especially with-
in the last few years, the prices have been high. The
following table may be of some interest, as it shows
the fluctuations and steady increase of price, and also
gives some idea of the amount of coal burned and the
shipping necessary to supply this coal :

due to defective arrangement of boilers, it was de-
cided to stop at the end of twenty-two hours to make
alterations.
This was the first test made of Coalinga oil at the
Western Sugar Refinery and was made under unfa-
vorable conditions, but on the strength of this test
the whole method of heating was changed.

table, which shows a saving of $46,012.15 per year by
burning oil. But as it was based on the first test, it
is safe to say that the minimum saving over coal is
$60,000. This does not take into account wear and
tear on the boilers, and general convenience :

This table is made up of average coal tests and
compared with oil at $1.30 per barrel, and an aver-
age evaporation from and at 212° of 15.5 pounds. The
intermittent demand for steam at the refinery does
not allow them to work all the time on the most eco-
nomical methods, and instead of a test evaporation of
16.4 pounds, the average evaporation comes to 15.5
pounds.
Many tests have been made at the refinery with
air-blowing instead of steam, and it has been found
cheaper, but as their demand for steam is subject to
extreme fluctuations and as air-blowing does not " re-
spond " as quickly as steam-blowing, it is not used
under their boilers. It is now used under their kilns
and gives great satisfaction. For a plant where the
demand for steam is constant, it is much cheaper to
use air-blowing. A different kind of a burner must
be used ; instead of the lip of the nozzle being less than
1 inch wide, as in a steam burner, it must be from 25
to 3 inches wide, according to the flame desired. Air-
blowing does not give as perfect a flame as steam-
blowing, because the latter heats the oil and vola-
tilizes it.
In using air to blow with, practical tests show that
about 15% more air must be added than is necessary
for complete theoretical combustion.
The National Ice Co. of San Francisco has burned
crude oil with great success for some time. Their
boiler plant generates about 250 H. P. They have
until lately burned Los Angeles oil of 11° to 12° grav-
ity, but tests are now being made with Coalinga oil.
Five per cent of the generated steam is used to blow
with, but an air-blowing appliance is soon to be put
in. Their grate construction is a peculiar one, and,
from the results and experiences of others, seems to
be rather poor and wasteful. No target is used, the
grate bars simply being covered with loose firebrick
and the flame is shot along the bottom of the boiler,
as in accompanying engraving. (See Fig. 4.)

Probably the greatest future for crude oil burning
in California is in metallurgical work, for there seem
to be but few processes where it can not be applied.
The Selby Smelting Works furnish a fine example of
what can-.be done in this line with fuel oil. Here
three Ropp furnaces and one Pearce furnace are
fired with oil and give great satisfaction. The
amount of heat to be used can be adjusted to such
nicety that a saving can be effected. It needs no at-
tention, and as there are no furnace doors to open
and shut, the constancy of the air supply is never
disturbed.
Two different methods are used for firing the Ropp
furnaces. In one the burners are on the side of the
furnace and in the other they are inserted through
the top and point directly downwards. Mr. Ropp
considers the latter method to be the more success-
ful. Oil is also used in melting down the precipitated
silver in a reverberatory furnace, in the retorts and
in a large reverberatory slag furnace. Exact com-
mercial figures could not be given, but it was under-
stood that it was cheaper than coal, not to speak of
the convenience and perfection obtained. The oil
used is Ventura oil and is pumped from the Union Oil
Refinery. All the oil used is blown with steam, air
not having been tried as yet, but there seems to be
no reason why it should not work equally well.
California contains rich copper ores which have not
been worked, mainly on account of the high price of
suitable fuel. It appears that the solution of this
problem has come, and that crude oil is the key. So,
in many respects, this natural fuel promises much,
but it needs capital to make the necessary experi-
ments. As a steam producer its value has been un-
doubtedly proven, at least for plants exceeding 100
H. P., but for the other uses experiment must yet
determine its value.
For the tables and figures herein given, and for
their kindness and assistance, I am indebted to Mr.
Oswald Rothmaler, manager of the Western Sugar
Refinery ; Mr. W. J. Wayte, engineer of the Western
Sugar Refinery ; Capt. Quinan, superintendent of the
California Powder Works ; Mr. Alfred Ropp, mana-
ger of the Selby Smelting Works, and Mr. Palmer,
manager of the Union Oil Refinery.
A Tale of Two Engines.
" I saw two beautiful engines recently," says a ma-
chinery man, " that were perfect twins in every par-
ticular except one — there was a difference of about
$400 in their cost. In design, finish, size, weight,
power and every mechanical detail they were as like
as two peas, and, as a matter of fact, they were
from duplicate patterns, built in the same works at
the same time. The variation in price was due to a
curious business principle of the firm of builders,
which, by the way, is one of the largest and wealthi-
est concerns in the country. The establishment
never undertakes to construct an engine for a fixed
sum of money. When it executes an order a careful
account is kept of every item of expense — the cost of
September 22, 1900.

material, the pay of the men, the wear aud tear of
the tools, and anything else that contributes to the
outlay. Then a fixed percentage is added for profit,
the figures footed up and a bill rendered for the sum
total. Now, anybody who has ever had any experi-
ence with machinists and machine building," con-
tinued the speaker, " knows perfectly well that no
two men can accomplish exactly the same results.
They will have their good days and their bad days,
and unavoidable accidents, delays and breakage will
sometimes make a difference of hundreds of dollars
on identical jobs. As far as I know, all firms except
the one I am talking about have a scale of averages
on which they base their charges, and, while they
occasionally lose on some particularly unluckly piece
of work, they make it up on the next. But this house
has always stuck to the old-fashioned, primitive
system of charging the actual outlay plus a fixed
profit, and it enjoys such a reputation for fair deal-
ing that its figures are never questioned. Exactly
what percentage repesents the profit I am unable to
say. I have heard it stated at all the way from 5 to
15; but, whatever it is, it never changes and is ex-
actly the same for big jobs and small."
Mines of Rico, Dolores County, Colo.
Rico is on the Dolores river, at an altitude of 8700
feet, in a section where the mountains are neither so
high nor precipitous as is the case near Telluride and
Ouray. The location of the mines here range from
9000 to 10,500 feet altitude, the slopes of the hills
being such as to make the roads and trails that
traverse them of comparatively easy grade. All min-
ing interest centers on three different hills — Dolores
and Telescope mountains, on the east side of the
river, and Expectation mountain, on the west side.
The earlier workings, which for years made Rico an
active mining center, comprised those of the Enter-
prise and Rico-Aspen, on Dolores mountain, and the
through Telescope mountain, across Silver creek, into
Blackhawk mountain on the southeast, the Black-
hawk being a spur from Dolores mountain. This takes
in a distance of about 3 miles, and the fissure has
been opened at points on contiguous claims the en-
tire distance. The Leap Year appears to branch off
from the Logan fissure on the southeast side of Tel-
luride and join it again on the northwest side. The Bour-
bon fissure has been opened only on the western slope of
Telescope and seems not so well marked as the Logan.
The latter fissure is from 10 to 25 feet wide, carrying
a lead and copper sulphide, with silver, lead and gold
values; but at present depth of workings on this fis-
sure the formation is so broken that the principal
values have filtered down, and better values must be
looked for at greater depth, where the formation is
solid and the walls are intact. But the contact
veins, which are an overflow from the fissures, lie be-
tween an iron capping above and a lime bedding
plane below. These contact deposits drop down in
benches, following the structure that has broken
from the main formation and slid downward. Where
the lime bedding plane is horizontal the values are
held ; where it is turned on edge the values have
leached down and the ore thus found is low grade.
The material, since being thrown from the fissures
into contact deposit, has undergone a change — from
a sulphide in the fissure to a carbonate in the con-
tact. This has been demonstrated by the workings
on the C. H. C. contact, from which a great many
thousand tons of carbonate ore were shipped a few
years ago, and by the workings on the Logan fissure,
whose ore has been largely a sulphide of iron and
lead. Over on Dolores mountain, in the Enterprise,
for instance, the ore bodies were found in fissure
veins, contact deposits and vertical stringers, but
the formation was less broken, the vein matter more
in place, and the values were uniform near the sur-
face, because the walls were intact, and the ore itself
was a sulphide, with no carbonates, as is the case
on Telescope.
Two groups on the northwest slope of Telescope
mountain, known as the Wellington and Logan
Mines of Rico, Dolores County, Colorado.
C. H. O, on Telescope. At a point in the north end
of the town there appears to have occurred an up
heaval, from which the formation dips. Thus, the
strata of Dolores mountain dips, in the main, to-
wards the south ; that of Telescope to the north and
northeast, while the dip of Expectation range corre-
sponds to that of Dolores on the south and to the dip
of Telescope on the north end.
The vein structure and ore bodies of Dolores and
Telescope mountains have been pretty well exploited
and determined, being quite similar on the two moun-
tains, though different as regards character of ore.
In general, the ore is found in nearly vertical fissures
and contact deposits which apparently Were fissures;
there are also numerous vertical veins which form
a part of the somewhat broken and irregular
structure.
Telescope mountain is characterized by three great
fissures cutting through it from northwest to south-
east, nearly paralleling each other and being about
1000 feet apart at the apex of the mountain. These
are locally known as the Logan, Leap Year and Bour-
bon fissures. The Logan, being the principal one,
has been traced from Horse gulch, on the northwest,
groups, comprising about eighty-five acres, cover
most of the claims on the Logan fissure and part of
the Leap Year fissure, as well as a large portion of
the contact ground lying on the slope adjacent to
these fissures. These groups are in control of
David Swickhimer, either by ownership or under bond
and long-time lease. Much work was done on the
two groups several years ago in the shape of tunnels,
drifts and shafts. Considerable new work is now in
progress. On the west end of Logan group a tunnel,
700 feet long, cuts along by the side of the fissure and
on the contact; from it a drift is being run eastward
to cut' the -Leap Year fissure and to open the contact
between the two.,. The Logan fissure is also opened
on the Uncle Ned, near the crest, on the Avalanche
and Argentine, on the southeast slope, and on the
Blackhawk and Little Maggie, on Blackhawk moun-
tain. The Mountain Spring tunnel cuts 940 feet into
the Wellington group, connecting by an upraise with
the old Wellington level, from which considerable ore
has been shipped. This tunnel goes toward the Logan
fissure, and if driven 1000 feet farther would cut the
latter at 1000 feet depth. But, as this tunnel level
is below the contact, the new Wellington tunnel is
being driven higher up the slope to cut the fissure
at 1250 feet from entrance and 750 feet depth. It is
believed that this tunnel will open the Logan fissure
in solid formation, and will cut through a known con-
tact of ore. Mr. Swickhimer and associates are not
only developing the two groups named on the north-
west slope, but the Uncle Ned, near the summit, and
the Argentine, on the southeast slope, which they
own. Following the Logan fissure into the Black-
hawk and Little Maggie workings, the ore becomes
a sulphide, with some zinc and heavy lead values.
Summarizing as to Telescope hill, the contact ores
above the horizontal bedding planes are high grade,
carrying silver and lead; great areas of such ground
remain undeveloped. But the fissures, especially on
the northwest slope, which are opened only to a depth
of 200 feet, have at this depth broken walls and low
values in silver, lead and gold; but future work is to
determine whether there are higher values at
greater depth, where the walls and formation are
solid.
On the northern section of Expectation mountain I
went into the Sambo, which is developed by a 400-foot
tunnel, a 250-foot drift and some stoping. Here is
found a contact vein between a lime and sandstone
wall above and a stratum of " short lime " below.
The ore carries a sulphide of lead, with some zinc.
Here the contact is much broken, showing evidence
of that section through which the tunnel goes having
slid downward ; but, on going in on a tunnel at a
higher elevation, a point is reached where the forma-
tion is regular and the contact in place. Here the
contact dips to the north about 7 feet to the 100
feet.
The lower bench of Dolores mountain, sloping to-
ward the river, is called Enterprise hill, being the
location of the Enterprise mine, originally opened by
David Swickhimer. The Group tunnel, located by
Charles Newman after the Enterprise mine was opened
on a bench higher up, undercuts the Enterprise con-
tact, having upraises to it. This tunnel has been
driven about 5000 feet from the entrance, connecting
with over 30 miles of workings on the contact above
it. Last year a concentrating mill was erected,
just below the Enterprise dump, by the Colorado
Milling & Concentrating Co., made up of Telluride
and Pittsburg people. It was equipped with
crushers, rolls, Huntington mills, gravity sizers
and Wilfley tables. The sizers grade the ore
for the different tables. The Huntingtons grind
to about 30-mesh. The mill was built to run on
a dump of about 750,000 tons, on ore from the
old stopes and low-grade ore in place. The
values in the dump are believed to run not lower
than $4.75 per ton; that of the stopes, $4.75 to
$7.50 per ton; the product is about one-third gold
and two-thirds silver and lead. This company
has a time lease on the dumps and stopes men-
tioned. The mill has run part of the season
and will soon start up again. The concentrate
product, resulting from reducing about thirty
tons to one ton, carries 25% to 30% iron, 9% to
11% silica. This enormous dump is the refuse
from eleven years operating, during which time
nearly $10,000,000 were produced.
Farther southward on Enterprise bench of Do-
lores mountain are the Rico-Aspen, Newman
group, Jumbo and other well-known mines.
From a point up Silver creek the Scoutt tunnel,
now in 2000 feet, is designed to cut under the
same contact at greater depth than are the En-
terprise or Rico-Aspen workings.
The zinc proposition is of special interest at
Rico at this time, because of the possibility of
zinc production becoming an industry here.
Thomas Jones, representing George E. Nichol-
son, operator of zinc works at Iola, Kan., and
Nevada, Mo., has been on the ground for some
time and has secured a five-year lease on 230
acres on the south spur of Expectation moun-
tain and twelve acres on Enterprise hill ; and
may negotiate for the Atlantic Cable group of
fifteen claims, extending from Expectation range
northeasterly. Mr. Jones has also acquired the
old sampler and concentrator, on the railroad
track, which he is equipping for a zinc con-
centrator. With this he hopes to be able to
make a fairly clean separation of the zinc sul-
phides from the lead and iron. He will use
crushers, rolls, jigs and tables. There are zinc ore
bodies here, specimens of which run from 50% to 57%
zinc ; but the extent of such ore has not been fully
determined. The Missouri zinc ores are a "black-
jack," theoretically two-thirds zinc and one-third
sulphur. But the zinc here consists of a brown zinc-
blende, containing a good per cent of silica, and asso-'
ciated with chalcopyrites and lead, the crystalliza-
tion of sulphur giving it the brown color; also is found
here the " rosin-jack," a zinc ore, which is free from
gangue and other- material. Both these classes of
zinc ores here are mechanically, not chemically, com-
bined with lead, iron and other minerals, which makes
possible a separation by concentration. In some
special cases, however, the chemical combination does
exist in Rico ores. The zinc ores at Leadville are
chemically combined with iron and lead and are
strictly a smelting proposition. In an open cut on
the Atlantic Cable they ran through a cap rock of
lime into a zinc sulphide, with crystals of galena; 200
feet north of this point a shaft was sunk ?5 feet, get-.

ting into specular iron, with no zinc. Zinc ores were
found also on the Argentine, up Silver creek ; also,
on the Shamrock, a quarter-mile west of the original
open cut on Atlantic Cable. On the Silver Swan
group, leased by Mr. Jones from J. J. Cohnan, there
is a 1000-foot tunnel, with upraises on vertical veins
to a contact, bearing a very pronounced character of
zinc ore, associated with lead and chalcopyrites.
Mr. Jones has just shipped fifty tons of Rico's typi-
cal zinc ore to his works at Nevada, Mo., on which
to make a test run.
The Rico district has been very quiet for several
years, but there are good indications of a revival of
former activity. Wascott.

Filtration Instead of Distillation for Petroleum.
It has been known for years that, when lubricating
oils or warm vaseline, and especially cylinder oils,
are filtered through animal charcoal, and more re-
cently through fuller's earth, the color is made much
lighter. It is now well known also that this filtration
changes the specific gravity and the corresponding
viscosity of the oil, says David T. Day, of the U. S.
Geological Survey, in an address at Paris before the
Petroleum Congress, assembled at the Exposition.
" The fuller's earth used for this filtration is a very
porous .variety of clay, so porous that it adheres
tightly to the tongue. Chemically, it is a clay very
rich in silica and in combined water. There is great
difference in appearance and in chemical composition
between the fuller's earth from different localities.
For example, there are two quite different varieties
of fuller's earth from Reigate, Surrey, England, and
both differ markedly in composition from the variety
of fuller's earth found in Florida. This latter also is
preferable as a filtering material for petroleum oils.
"These different varieties of fuller's earth shade
into the other varieties of clay, and their filtering
capacity likewise grades off, and we find that ordi-
nary shales and clays show some filtering capacity,
though perhaps not more than one per cent as great
as with the best fuller's earth. Fine sandstones,
however, show little or no filtering capacity.
"Naturally, the partial separation of the oils in
crude petroleum by filtration, as \ have shown it,
offers good hope for complete separation by this
means, and as such I humbly offer this method through
this Congress to the investigating world, and wish
to state that I believe, before the next winter is
past, I will have effected entire separations.
"The first efforts will be guided by what we know
we can effect by distillation, and small quantities of
my filtrates will be tested until they show constant
boiling points and other characteristics of simple
chemical compounds. But even if only primary
separations could be effected by this means of heavy
(and easily decomposed) hydrocarbons from lighter
ones, so that in distillation the latter might not be
distilled by the former, a great advantage would
have resulted. But I believe that we will effect
complete separations.
"As to the practical value of this process, its
great promise is as a scientific means of separating
the mixtures of oils with which we now deal. Imagine
the gain if we can thus define as a standard of quality
for a given lubricating oil that it shall contain fixed
percentages of definite hydrocarbons, instead of refin-
ing the oil by flashing point, density and viscosity.
Further, when we know which of these funda-
mental hydrocarbons yield the most beneficial oils we
can then regulate our processes of manufacture to
secure the greatest yield of these constituents."
Underground Oil Tanks in Canada.
Canadian oil producers use for storing crude oil
holes dug in the ground, thus described by J. D.
Noble:
These underground tanks are circular in form and
dug to any capacity required, the clay in the Cana-
dian oil region being specially adapted for this pur-
pose. There is 100 feet of tallow- waxy kind of blue
clay to go through before the top rock is reached; a
number of petrified cockle shells are found in this
clay, which clay is perfectly impervious, and so com-
pact that it will hold either oil or water when the
hole is dug out without leaking a drop. Expert
workmen trim down the walls with their spades until
they become smooth and shining, and when the hole
is dug out they commence at the bottom and ring it
up to the top with solid wooden rings. These rings
are formed of kants, which are pieces of Canadian
pine lumber cut in the form of the segment of- a cir-
cle, and shaped just to fit the circular wall of the
tank; they are from 3 to 4 feet long, according to
the size of the tank, 5 inches wide and 1 inch thick,
and the joints are covered by the top piece as the
workmen proceed to nail them together from the
bottom and ring up the tank. This wooden lining is
put in to prevent the possibility of any clay caving
in. The tanks for holding crude oil are generally
dug 30 feet in diameter and 60 feet deep, and hold
about 8000 barrels in bulk of thirty-five imperial gal-
lons to the barrel. It is only after sinking down
about 20 feet that this peculiar formation of tallow-
waxy kind of blue clay is found, the first 20 feet be-
ing a rich alluvial deposit formed from the dropping
of the leaves of the trees for a long period of years.
The blue clay is taken from the bottom of the tank,
and puddled about 1 foot thick behind the wooden
curb for the first 20 feet, thus forming a perfect
water-tight tank, which is then covered by large
timbers and 2-inch planks with a coating of gravel
on top. Oil has been held in such tanks for ten
years without leaking a drop, and there is no danger
from lightning, which has caused so many disastrous
fires from oil stored in large iron tanks.
The Canadian crude petroleum when pumped from
the wells is of a dark green color, and the gravity is
from 32° to 37° by the Beaume hydrometer, accord-
ing to the locality in which it is pumped. It is worth
at present 7s per barrel of thirty-five imperial gal-
lons to the barrel, in bulk at the wells, and it costs
2s per barrel to produce.
There are no flowing wells in Canada; all the oil is
produced by pumping. The crude oil when distilled
contains 5% of benzine and 42% of illuminating oil.
After the illuminating oil is taken off, the heavy
vapors are blown out of the still by an injection of
steam and condensed and sold for gas or liquid fuel,
and the balance of the still is petroleum tar, which is
very rich in paraffine, and from which a large per-
centage of wax is obtained for making candles. It is
also manufactured into lubricating oils of the very
finest quality, and the residue makes a very superior
fuel, being very rich in carbon.
The wells are 4} inches in diameter and 475 feet
deep. At a depth of 460 feet the oil-bearing rock is
pierced, and at this point a nitro-glycerine torpedo
is exploded to shatter the rock and allow the oil
more freely to flow into the well.
Experiments Regarding the Influence
of Silica on the Loss of Silver
in Scorification.*
The fact that the loss of silver in the slag of the
smelting process increases with the amount of silica
in the furnace charge was probably the ground of a
general opinion that the silver is present in the slag
as a silicate. Dr. lies, in his interesting experi-
ments upon the slags of scorification, found in no in-
stance any silicate of silver. These experiments,
however, were made with pure crystals of AgN03 —
a circumstance which may have affected their re-
sults, since it is conceivable that an intimate mixture
of metallic silver with silica might more strongly
favor the formation of a silicate. Fusing at a low
heat for three hours, and then allowing to cool, 6.8
grammes of AgN03 with 1.2 grammes of pure an-
hydrous Si02 (these proportions corresponding to
the equation 2 AgNO= + Si02 = Ag2SiOa + N202 + Os),
Dr. lies obtained a bright brick-red slag, the color
of which was due to Ag202.
The only other experiments of interest bearing
upon this subject are the crucible assays reported by
Mr. Furman, of which Nos. Al and A2 have special
interest. In these instances he assayed 108.15 and
102.75 milligrammes of silver with J A. T. of Si02,
and found the losses to be 2.47% and 1.93%, respect-
ively. These are small losses. With low-grade ores,
Mr. Dewey found the loss higher, as was also the re-
sult in the experiments described below. Mr. Fur-
man assayed also 116 milligrammes of silver with 7.5
grammes of Si02 and 7 grammes of FeS, and found
the loss of silver to be 4. 66%. This is smaller than
the losses (5.2% and 5.3%) shown by Experiment No.
4, described below, in which Si02 and FeS2 were in-
gredients. It would seem that, in an assay of silver
with silica, the presence of a sulphide of iron tends to
keep the loss of silver nearly constant.
In order to test the influence of silica in the scori-
fication assay, the following experiments were made:
In these experiments pure ores (pyrite, zincblende,
galena or stibnite), sulphur, silica and test lead — all
free from silver — were mixed with filings of silver,
0.992 fine and free from iron. No borax glass was
added, since it was desired to avoid, as far as pos-
sible, the introduction of factors which might affect
the result. In all cases, with two exceptions, the
temperature of scorification was between 900° and
1000°C. The cupellations were made with "feathers."
The influence of silica being the special object of
inquiry, other conditions (such as temperature,
amount of silver and amount of test lead) were kept
as nearly constant as possible to facilitate the com-
parison of results.
The table below shows the quantities of each in-
gredient of the charge and the results obtained,
other conditions of the experiment being stated in
the following:
Remarks. — All the assays were made in duplicate.
In the column under " Silver," the amounts of silver
actually weighed out are given. The following col-
umns, for comparison only, give the average results.
Experiment No. 1. — In this case the "low heat"
was just sufficient to melt the lead, and the smaller
percentage of silver recovered was due to the long
period of scorification, which permitted a larger
quantity of silver to enter the slag. The "high
heat " was a white heat, and the loss here was prob-
ably due to volatilization.
* Lester Strauss, Canadian meeting, August, 1900, American In-
stitute of Mining Engineers.
Experiment No. 2. — As was to be expected, these
assays show increasing loss of silver with increase of
silica.
Experiment No. 3. — Here the addition of 6
grammes of SiOa increased the loss of silver.
Experiment No. 4. — In this case the addition of
Si02 increased the loss of silver; but variation of the
ratio of Si02 to FeS2 seems to have had no material
effect in this respect.

Experiment No. 5. — The assays show that the ad-
dition of silica increases the loss of silver and that
this loss is diminished by a decrease in silica and an
increase in zincblende. The well-known effect of zinc-
blende, per se, in augmenting the loss of silver was
shown by additional assays (not reported in the table),
in which still larger quantities (6, 8 and 10 grammes)
of zincblende were present, with no silica. These as-
says yielded black, pasty slag and very brittle (and
in the last instance, with 10 grammes of zincblende,
very small) buttons, which could not be cupelled.
Experiment No. 6. — In these assays the amount of
test lead added was so proportioned to the lead in
the galena as to make 50 grammes as the total lead
in the charge. With 4 and 10 grammes of galena the
results were peculiar, the loss of silver being smaller
than with 2 grammes of galena, while the assays with
6 and 8 grammes of galena showed proportionately
larger losses of silver. The addition of 6 grammes of
silica, 1.5 grammes of galena being present, was fol-
lowed by increased loss of silver ; but the combination
of 3 grammes of galena with 2 grammes of silica re-
sulted in the recovery of the largest percentage of
silver, with one exception, in the whole galena series.
Experiment No. 7. — In these assays the increase
of sulphur in the charge from 0.5 to 1 gramme seems
to have reduced the loss of silver, as the increase of
sulphides seemed to do in preceding experiments.
But the reduction of silica from 6 grammes to 2
grammes increased, as in other cases, the proportion
of silver recovered.
Conclusions. — The preceding experiments indicate
that the behavior of the metallic sulphides in scorifi-
cation with silica and silver is not uniform, but varies
with the nature of the ore. Evidently more extended
investigation would be necessary to determine the
cause and law of this variation. These experiments,
however, appear to warrant the following conclusions:
1. That in assays of pure silver and lead an in-
crease in the amount of silica present increases the
September 22, 1900.
Mining and Scientific Press.
343
106S of silver in the slag. This fact was already well
known.
2. That in the presence i>f sulphides an excess of
silica increases the silver loss, but that this loss is
apparently diminished when sulphides are present
with a relatively smaller amount of silica.
3. The experiments, though by no means conclu-
sive, suggest that the same recovery of silver cannot
be expected from different mixtures or ores of the
same silver value.
Dr. Koenig, after observing that the student
(operating with various type mixtures, each contain-
ing exactly HUU ounces of silver per ton) "finds that
the loss of silver is not at all the same, but that this
loss can vary from H% to 16% with the best work
possible," adds that an assay "made with clean
sand, the HO milligrammes of silver wrapped in lead
foil, being placed on the top of the charge, sand and
test lead, * gives the minimum loss." The
experiments above reported and the results obtained
by Messrs. Furtuan and Dewey seem to require a
modification of this statement, since they indicate
that the silver loss would be dependent upon the
amount of silica present, as well as upon the other
ingredients of the charge.
My thanks are due to Dr. E. H. Miller for friendly
advice and assistance in the experiments above de-
scribed.

Volumetric Method for the Determi=
nation of Copper.
By Richard K. Meade.
The average analyst is often deterred from the use
of a volumetric method by the necessity of making
and standardizing a special solution. In many cases
it takes nearly as much time to ascertain the
strength of the required solution as it does to make
the analysis itself, and the standardization and anal-
ysis together render the volumetric method fre-
quently as slow, if not slower, and vastly more
toublesome than the gravimetric determination.
Volumetric analysis, therefore, becomes more and
more an ideal method of quantitative determination
as it approaches the requirement of a single standard
solution, capable of having its strength accurately
determined by simple means, giving a clear, definite,
clear end-reaction.
In iron and steel laboratories permanganate is fast
coming to the front as a help to rapid analysis. Iron,
phosphorus, manganese, sulphur (Payne's iodine solu-
tion is prepared by adding standard permanganate
to potassium iodide), and calcium can all be quickly
determined by the use of one standard solution.
"While it may never be possible to supplant other
standard solutions by permanganate, still the sphere
of its usefulness is a large one and is constantly en-
larging.
A new method for the determination of copper by
permanganate, which seems to possess many points
over the old one of reduction by grape sugar, in gen-
eral is as follows : The copper is brought into solu-
tion as a sulphate, either by dissolving it in sulphuric
acid or evaporation of its solution with sulphuric
acid. The greater part of the free acid is neutral-
ized by ammonia, the solution warmed, sulphurous
acid added until the solution smells strongly of the
reagent, and then a slight excess of ammonium or
potassium thiocyanate. The copper is immediately
precipitated as cuprous thiocyanate. Stirring and
wanning renders the precipitate heavy and easily
handled. ' The solution is filtered through asbestos,
using the pump, and well washed. The precipitate
and filter are thrown into the beaker in which the
precipitation was made and heated with a solution of
caustic soda or caustic potash. Double substitution
takes place. Hydrated cuprous oxide and potassium
or sodium thiocyanate result.
2CuSCN + 2KOH = Cu2(OH)2 + 2KSCN.
The oxide is filtered on asbestos and washed well
with hot water. The precipitate and filter are again
placed in the same beaker and an excess of ferric
chloride or ferric sulphate (free from nitric acid, free
chlorine or ferrous salts), together with a little dilute
sulphuric acid, added. The copper oxide reduces a
corresponding amount of iron from the ferric to the
ferrous condition.
CuzO + Fe2ClG + 2HC1 = 2CuCl2 + 2FeCl2 + H20.
The beaker is warmed and stirred until all the cop-
per oxide is dissolved. The solution is then poured
through a perforated platinum disc and the asbestos
which stays behind upon it washed with water, to
which has been added a little sulphuric acid and a
little ferric chloride or sulphate. The solution is then
titrated with permanganate. The iron equivalent to
the permanganate used multiplied by 1.125 gives the
weight of copper in the sample.
Instead of sulphurous acid, ammonium or sodium
bisulphite may be used to reduce the copper. A
solution of equal weights of sodium bisulphite and
potassium thiocyanate answers well as a reagent for
the precipitation of the metal. Since copper is the
only metal precipitated by an alkaline thiocyanate
from an acid solution, the presence of arsenic, anti-
mony, bismuth, zinc and other materials which ren-
der the electrolytic, the cyanide and the iodine
method inaccurate will not affect the results.
The caustic alkali solution, used to convert the
cuprous thiocyanate into cuprous hydroxide, must
not be too strong or some of the metal will go into
solution, coloring the liquid blue. I have used about
a half normal solution of caustic potash, made by dis-
solving twenty-eight grammes of the salt in a litre of
water. Either ferric sulphate or ferric chloride may
be used to dissolve the cuprous oxide. The former is
probably the safest, but the latter appears to dis-
solve the precipitate the more readily of the two.
As a test of the accuracy of the method four
grammes of pure electrolytic copper were dissolved
in nitric acid and the solution evaporated with sul-
phuric acid until the nitric acid was expelled. The
solution was cooled and diluted to one litre. The cop-
per contained in fifty c.c. was then determined elec-
trolytically with the following result :
Gramme.

2 0.2003
3 0.2000
4 0.1997
Average 0.2001
The copper in fifty c.c. was determined by the
thiocyanate - permanganate method outlined above.
The permanganate solution used was made by dis-
solving 5.02 grammes of pure crystallized potassium
permanganate in water and diluting after standing
twenty-four hours to 2 litres. Its strength was
determined by titration against iron wire and against
ferrous ammonium sulphate.
Against ferrous ammonium sulphate :

1. One c.c. = 0.004455
2. One c.c. = 0.004456
Against iron wire :

3. One c.c. = 0.004460
4. One c.c. = 0.004449
Average one c.c. = 0.004455
One c.c. = 0.004455 X 1-25 = 0.005012 gramme copper.
Below are the results on fifty c.c. of the copper
solution containing 0.2001 gramme copper by the thio-
cyanate-permanganate method :

6 39.8 0.1995
In determination numbers 1, 5 and 6 ferric chloride
was used to dissolve the cuprous oxide ; in numbers
2, 3 and 4 ferric sulphate was used.
As a further and more practical test of the method,
the copper in some samples of copper was carefully
determined by the electrolytic and then by the thio-
cyanate-permanganate method. Below are the com-
parative results :

Preparation of Roofing Slate.
In the last few years California has produced 23,-
450 squares slate. A square of slate is 100 square
feet as laid on the roof. El Dorado and Shasta coun-
ties furnish the most of California slate, the demand
for which is still limited. As population increases
the demand for slate will be more commensurate with
its merits. In some Eastern States the slate indus-
try is a great one. From January 1 to August 23,
1900, Slatington and Walnutport, Pa., shipped 122,952
squares of slate. In Allen town, Pa., is published a
trade journal styled Cement and State. To it we are
indebted for the accompanying illustration depicting
the preparation of roofing slate for the market.
The illustration on this page represents the interior
of a slate shanty on the bank, where roofing slate
is split and squared ready for the market.
The large blocks are broken away from the strata
or ledges in the quarry principally by blasting, and
then worked away from their position and loaded
upon small platforms, which are raised by means of a
wire rope running along a stationary cable. This de-
posits it on the bank, either near the shanty or upon
a truck, by means of which it can easily be trans-
ferred to that place.
Here it is dumped with many more of its kind,
although it is not very good management to have too
many blocks waiting to be cut, for if they are
allowed to dry out, it is almost impossible to cut
them up without a great deal of waste. To prevent
this drying out, wet cloths are sometimes spread
over the blocks, or they are wetted by sprinkling
water over them. Three men are required to change
the rough angular blocks of slate rock into the regu-
lar shapes of roofing slate. The first one "makes
the blocks," that is, he makes a mental calculation
as to what size of slate can be cut most advantage-
ously from the rock before him. On this man's judg-
ment depends the size of the waste heap, and conse-
quently the size of the dividend at the end of the
year. He must be able to judge rapidly and accu-
rately the proper cuts to run across the stone.
To cut a large mass of stone, such as this is, at
will, requires considerable skill. It is done in this
way: The stone is laid on end and a groove cut
across the edges of the laminfe, the same is repeated
on the other side and a thin line chiseled out, con-
necting these two grooves. Sometimes while this
last line is being cut, the stone separates, but fre-
quently it must be stood on end and broken with
blows from a hammer.
After these blocks have been formed, the slate
splitter takes them, and by means of a thin wedge or
chisel, which he inserts between the ends of the
leaves, he splits them into pieces of the required

is quite rapid. Not counting the time required for
solution of the ore, duplicate analyses can be easily
made in from a half to three-quarters of an hour.
In the writer's opinion the process is superior to
both the iodine and the cyanide method. It requires
the use of no rapidly changing solutions,' but one
which every analyst has on hand nearly all the time.
The. end-reaction is clear, distinct and familiar to all
chemists.. The method is applicable to any'ore, matte
or alloys. It is as rapid as the cyanide, except in
certain cases favorable to the latter, and more rapid
than the iodine method. Finally, not the least of its
points of advantage is that it is more accurate than
either of the two.
On the occasion of the recent celebration in San
Francisco of the fiftieth anniversary of California's
statehood 13,000 additional electric lights illuminated
the principal streets.
thickness. After these blocks have been formed, the
slate splitter takes them, and by means of a thin
wedge or chisel, which he inserts between the ends
of the leaves, he splits them into pieces of the re-
quired thickness. To do this well requires expe-
rience, for if the slates run very uneven, as to thick-
ness, they make poor roofing material. The pieces
of slate are still irregular in shape and to put them
into marketable condition they must be cut to size.
This is done by the dresser. Before him stands what
might be called a skeleton table, at one end of which
is a knife operated by foot power. He first cuts a
straight edge on the slate, then lays that edge along
a line or pushes it against the back of the machine,
which has been set for a ' certain size of slate and
brings down the knife, thus forming two straight
sides of the slate. The others are cut in the same
way. After this the square slates are transferred to
the shed on the bank and are ready for shipment.

The Colorimetric Assay of Copper.*
Ity J. D. audlct Smith, Clifton, Arizona.
Heine's " blue test" for copper, as described by
the authorities generally, calls for a set of standard
colors; and there has been some discussion concern-
ing the relative superiority, for this purpose, of sul-
phate and nitrate solutions. The whole matter evi-
dently hinges on the preservation of the standard
colors in well-stoppered bottles. The apparatus de-
scribed by G. L. Heath cannot be much improved,
when very accurate readings are required.
The following method was devised for the purpose
of doing away with preserved sets of standard colors,
by making a fresh standard for each batch of assays.
The solutions are prepared in the usual way, each
ammoniacal solution being filtered into its separate
bottle, and then filled up to the containing mark and
thoroughly mixed. A similar color bottle, with an
"S" etched upon it, to distinguish it from the other
bottles, which are numbered to correspond with the
samples, is kept to run the standard. About 150 c.c.
of water is put into it, and then the amount of acid
(sulphuric or nitric) present in each determination,
followed by 30 c.c. of ammonia (s. g. 0.90), which
should make the mixture strongly ammoniacal.
The liquid is now made up almost to the containing
mark (200 c.c), say within 1 c.c. The lowest assay
is selected first and placed alongside the standard,
which, at the beginning, contains no copper. A cop-
per solution is then dropped into the standard from a
burette; and after each addition the bottle is well
shaken and compared with the assay sample. This
operation is continued until the two shades match
exactly, when the burette is read and the assay re-
sult is calculated. The assay next in order of depth
of color is now taken and treated in the same way,
and so on, until the batch is completed. It will be
found that the volume of the deepest colors is from
1 to 2 c.c. less than the standard, which has in-
creased by successive additions of copper solution.
This is corrected by adding the necessary amount of
water to the assay, just before the last one or two
drops of copper solution are added to the standard.
DETAILS OF THE METHOD.
The copper solution contains 5 grammes c. p. cop-
per per 2000 c.c, and is made by dissolving the
metal in a small quantity of nitric acid and diluting,
so that 1 cc=0.0025 gramme Cu.
It is convenient to have a syphon attachment, for
filling the burette with this solution.
Tailings Assay. — One gramme is digested on
a hot plate with from 3 to 5 c.c of HN03
to 3 c.c of HC1, and 5 c.c. of H2S04. Rapid
heating will soon decompose the mineral; and the
treatment should be continued until the sulphur
globules which form are quite yellow. Add about 30
c.c. of water; then an excess of ammonia water (s. g.
0.90). Mix thoroughly and filter hot, through a S.
and S. folded filter No. 588 or a very rapid paper.
Wash the iron precipitate twice with TV ammonia
water; then dissolve off again into the original vessel
with 5 c.c of 1 to 1 H2S04 and hot water. By lift-
ing the filter and its contents out of the funnel, then
opening it out and washing back the precipitate with
a jet into the original vessel, the operation can bo
performed in less than a minute, and with very little
water. The solution is now reprecipitated with
ammonia, and the filtrate is combined with that ob-
tained from the first precipitation. One final wash-
ing is enough (r'5 ammonia) for any material not run-
ning over 1.5% of copper.
Slag Assay. — One gramme is boiled in a dish with
15 c.c. of water; then 5 c.c of HN03 is added along
with 5 c.c. of 1 to 1 H2SO,. The digestion is carried
on until the slag is thoroughly decomposed, and any
sulphur globules are yellow. It is not necessary to de-
hydrate the silica; and as decomposition is immedi-
ate, there is rarely any delay at this point. The
assay is now treated in the way as described above
for the tailings assay; only, care should be taken to
avoid using too large quantities of water in washing
and transferring precipitates. A third precipitation
of the iron has always resulted in a filtrate free from
copper when working on blast furnace slags; but in
analyzing high-grade slags, some copper may remain
in the second precipitate.
The standard is prepared as already described,
and the colors are carefully matched. When one
gramme is taken, each c.c of copper solution is
equivalent to 0.25% of copper.
The following table shows the results of a batch of
assays occurring in the daily work of a large copper
plant, and illustrates what may be expected from
the colorimetric assay in a busy office. The samples
are varied, consisting of mill tailings, slags and lean
ores. The results are not so close as those given by
Mr. Heath in his paper; but he says that his electro-
lytic assay was made on the solution which he had
used for his colometric assay. The electrolytic
assays tabulated below are separate determinations
on a separate weighing of the sample, the copper be-
ing precipitated from the acid solution of the ore

Green tints generally result in a low reading. Or-
ganic matter is the principal cause; but considerable
percentages of arsenic will also interfere, and pro-
duce tints which it is impossible to compare. Small
percentages of arsenic have no effect.
The advantages of the above method over the usual
method of using sets of standard colors are:
1. In a small office space is valuable, and a set of
standard colors will take up room which may be used
for something else.
2. An exact match is made with each assay.
3. The assays are read from a fresh standard,
and not from a bottle which may have been made up
months before.
It was found that Mr. G. L. Heath's bottle was
expensive, and easily broken. A bottle which is in-
expensive, stands the wear of the assay office of a
works, and, at the same time, gives excellent results,
is a square bottle, No. 5675 of Eimer & Amend's
catalogue, 2 inches in diameter, and 4| inches high
from bottom to neck, upon which any required mark-
ings for contained volumes can be readily etched,
according to the desire of the assayer.
The results tabulated above were obtained with
this bottle.
From the Sierra to the Sea.
The characteristic Sierra view caught in the
accompanying photographic picture suggests the
great mountain barrier along California's eastern
border and the service of the Sierra in the arrest of
transmission to the valley below for light and power,
suggesting the new-found relation of the torrents of
the Sierra Nevada to the industrial activity of the
State. All the way from this northern point in
Tehama county southward for 500 miles or more the
falling waters of the mountains are being used for
electric service, and the subtle current is conducted
scores of miles to do work in valley and coast re-
gions, a new phase of development, beginning to be
appreciated and utilized. The water itself is a great
agency in the development of the State, which has
never yet been conserved and employed except in a
small, fractional part of its possibility.
An Effective Pipe Wrench.
Manufacturers and mechanics,
having occasion to use the pipe
wrench, are interested in a late de-
velopment of that tool, as illus-
trated herewith. The Johnston
pipe wrench is intended to do away
with objectionable features of some
other wrenches, such as slipping,
crushing the pipe and getting out
of repair. The pipe illustrated can
not slip, for the greater the pres-
sure on the lever the greater be-
comes the grip upon the pipe. This
grip is effected in such a manner as
to keep from crushing or denting
the pipe, and the tool can not jam
or wedge past. As soon as the
lever arm is lifted, the jaw is auto-
matically loosened and the wrench
easily removed from the pipe. It
needs no adjusting when fitting to a
pipe, the movement of the lever
alone causing the jaws to grip fast.
There are but three parts — lever
and head, movable jaw and pin.
These are made of crucible steel,
drop-forged, and are interchange-
able. The manufacturer has agreed
to replace, free of cost, any parts
of these tools that break under fair
usage.
This wrench is made in three
sizes, having levers 12, 16 and 24
inches in length, respectively, and
these will fit pipes or bars ranging
from S inch to 2i inches. The wrench is manufac-
tured by Wm. B. Volger, 88 Chambers St., New York
City. They may be obtained of the Mine & Smelter
Supply Co. of Salt Lake City and Denver. They are
adapted for mining work, and are in use in Arizona,
Mexico, Pennsylvania and Alabama.

Constitutionally Affirmed.
To the Editor: — On page 91 of your issue of July
28 you assert as follows :
There is no law nor statutory provision in California
or any other State against hydraulic mining. In Cali-
fornia a decree of a court and injunctions under that
decree have interfered with hydraulic mining operations,
but Congress some years ago passed a law under which
hydraulic mining may be carried on. That law, known
as the Caminetti Act, has been declared to be constitu-
tional, in a case where its constitutionality was attacked
by a California hydraulic mining company at North
Bloomfield, Cal.
Now, I would like to know when, where and by
whom the "Caminetti Act" mentioned above was
ever "declared to be constitutional," and would also
like some information about the .facts in the North
Bloomfield case. S.
Sacramento, Cal., Aug. 31.
June 8, 1897, at Los Angeles, Cal., by Judge Ross
of the U. S. District Court. The North Bloomfield
Co. denied the constitutional right of the Act in ques-
tion to apply to its workings : Judge Ross affirmed
its constitutionality, and enjoined the mine.
The circumstances in detail were as follows :
The U. S. District Attorney, representing the
Government, brought suit against the North Bloom-
field G. M: Co., praying that a writ of injunction be
issued, prohibiting the company from continuing its
hydraulic mining operations at Humbug creek, a
stream within the territory drained by the Sacra-
mento and San Joaquin river system, Cal., as set
forth in the Caminetti Act.
On June 8th, '97, Judge Ross granted the writ as
sought for, in the TJ. S. District Court. In the com-
plaint filed by the District Attorney, it was set forth
that the mining company failed to file with the Debris
Commission a petition for a writ to carry on hydrau-
lic mining, and having failed to file such petition con-
tinued its operations of hydraulic mining; Further
than this, the complainant alleged, proper provisions
had not been taken for the impounding of debris, and
that such debris as was washed down operated
to impede navigation in the rivers, heretofore deemed
navigable, by settling on the bottom and raising bars.
In reply the mining company denied the allegation
that the debris from the plant impeded navigation,
but insisted that such as escaped their impounding
dam was of a flocculent nature and floated lightly on
the water, being ultimately carried out to sea. With
respect to the failure of the company to file a peti-
tion with the Debris Commission for a permit to carry
on hydraulic mining, it was contended that inasmuch
as no impediment to navigation was created as a re-
sult of the mining operation, therefore there was no
necessity to file such a petition. Furthermore, the
Bloomfield Company denied the right of Congress to
place restrictions upon the hydraulic mining industry,
such as established by the Caminetti law.
In his opinion Judge Ross reviewed the entire Act
creating the Debris Commission, and, commenting
upon it, said :
"From these provisions, and there is nothing in
the Act to the contrary, it seems quite clear to me
that its real intent and meaning is to prohibit and
make unlawful any and all hydraulic mining in the
territory drained by the Sacramento and San Joaquin
river systems, in the State of California, directly or
indirectly injuring the navigability of said river sys-
tems, or to the lands adjacent thereto ; and to per-
mit it in all cases where the work can be prosecuted
without such injury to the navigability of the said
river systems or to the land adjacent thereto.
"That in order to properly determine the facts
upon which the legislative will is to act, a skillful com-
mission is created, whose duty it is to ascertain and
to determine what will, or will not, cause the pro-
hibited injury, and to prescribe the character of the
impounding works and the extent to which hydraulic
mining in the territory described may be carried on
without such injury.
" To give effect to this manifest purpose Congress
in effect enacted that until the commission should
find that such mining can be carried on without caus-
ing the prohibited injury all hydraulic mining within
the territory drained by the Sacramento and San
Joaquin river systems is unlawful ; for by Sec. 9 it
is in terms declared that any person or corporation
owning mining ground in that territory, ' which it is

Then followed a number of citations from various
cases tending to show the power of Congress to de-
termine what may or may not be obstructions to
navigation. The case of the Brooklyn bridge was the
most important one recalled by Judge Ross. In that
instance it was positively held that only under cer-
tain specified conditions, such as would not blockade
or interfere with traffic on the river, could the bridge
be built. Therefore concluded Judge Ross:
" So here Congress has created a commission under
the direction of the Secretary of War and the super-
vision of the Chief Engineers of the Army to ascer-
tain and determine whether the various hydraulic
mines within the territory drained by the San Joaquin
and Sacramento river systems can be operated by
means of impounding reservoirs and other works
without injury to those navigable rivers; and, if so,
the Acts of Congress permit them to be operated in
such a prescribed way as will prevent any such
injury.
"Until the matters of fact committed to the com-
mission have been ascertained, and the extent and
methods of the works so prescribed, the Act of
Congress prohibits the operation of any mine by the
hydraulic process within the territory drained by the
San Joaquin and Sacramento river systems from
which any debris matter flows into those waters.
"This, in my opinion, is the true construction of
the Act, and to it; as thus construed, I see no con-
stitutional objection. * * * A decree will be en-
tered for complainant as prayed for."

now in use, can be done better, quicker and at from

The Black Range district is west of the terminus
of the Magdalen a branch of the railroad, and is in the
Town of Chloride, Sierra Co., New Mexico, Foothills of Black Range.
foothills on the east side and near the north end of
the Black Range. The formation is porphyritic,
principally andesite, and occasionally belts of tra-
chyte show themselves running parallel with the
veins. Limestone occurs in isolated places.
Every foot of the lode from Wild Horse creek to
Dry creek — 8 miles — is marked by croppings. The
vein is located the entire distance. The mineral belt
is from 4 to 8 miles wide. The accompanying illus-
tration of Chloride serves to give a general idea of
the country.
New discoveries in the Black Range are attracting
attention and the country is full of prospectors.
F. L. Buchanan, Supt. El Dorado mine, Hillsboro,
thinks that the ore is principally of a concentrating
character, and that deep mining will be necessary to
bring them into profitable operation. " I can show
claims in the Black Range that are literally cut up
with shallow shafts and open cuts from one end to
the other. All of these openings and cuts show the
vein plainly, and it is a wonder that the prospectors
did not go down when the vein was once found, for
the time and money scattered in useless surface work
would have developed the vein and made a mine of
the property. No man can hope to sell a mine for a
A New Enterprise.
The Risdon Iron Works of San Francisco have re-
cently purchased the property of the old Pacific Roll-
ing Mill Co. in the Potrero, Sari Francisco. This
property consists of some thirty- two acres of ground,
immediately adjoining the Union Iron Works, and has
a deep water frontage of over 1700 feet. Applica-
tion has been made to the Board of State Harbor
Commissioners for a site for a new dry dock. This
dry dock will be 500 feet in length by 100 feet in
width. New wharves are now in course of construc-
tion. Several new steel frame buildings are contem-
plated, and large orders covering the structural ma-
terials for the following buildings have recently been
placed:
Machine shop— length, 308 feet; width, 100 feet.
Total lift over main floor, 45 feet.
Boiler shop — length, 140 feet; width, 180 feet.
Total lift over main floor, 40 feet.
Machine and ship blacksmith shop —
length, 300 feet; width, 60 feet.
Foundry — length, 177 feet; width,
160 feet.
Ship joiner shop — length, 140 feet;
width, 81 feet.
The machine shop will be equipped
with four electric traveling cranes
of the following capacities: One
50-ton, one 20-ton, one 15-ton and
one 10-ton. Each crane will be of
the most modern type and equipped
with five-ton auxiliary hoists. The
boiler-shop crane equipment will con-
sist of one 60-ton, one 20-ton and one
10-ton electric traveling crane, each
equipped with five-ton auxiliary
hoists. The foundry crane equip-
ment will consist of one 30-ton and
one 20-ton electric traveling crane
with five-ton auxiliary hoists. The
ship blacksmith shop will be equipped
with eight jib cranes of five and ten
tons capacity each.
The machinery equipment through-
out will consist only of the most
modern tools. The entire plant, with
the exception of the steam hammers
in blacksmith shop, will be operated
by electricity, and contracts have recently been
placed with the Independent Electric Light & Power
Co. of San Francisco to furnish power for this plant.
Direct current will be used for the cranes and an al-
ternating current for the machinery equipment.
Separate motors will be installed in each depart-
ment. The cost of electric power for operation of
this plant for the first year will amount to over
$30,000.

fair price until he has shown what it contains at a
depth of 100 feet from the surface. Every foot less
decreases the price that can be obtained for the
property, even if it is a proposition of more than
ordinary merit. There are two lessons to be learned
in the Black Range. One is that deep mining will
seldom fail to find the values of very high grade, and
the other is that nine-tenths of all the ores are con-
centrating ores. One can mine and concentrate
three tons of ore for what it will cost to hand sort
one ton to make it high-grade shipping ore. Hand
sorting is an imperfect, slow and expensive method
.The Atlas Pipe Wrench.
The accompanying illustration is reproduced from
a photograph of an 18-inch Atlas pipe wrench in
operation on a 2-inch pipe, and demonstrates why it
does not crush the pipe. From an examination of the
illustration it will be readily seen that the teeth grip
the pipe at an angle and the gripping point is in ad-
vance of the handle, showing that in screwing a pipe
one pushes it ahead, and does not dig into the pipe and
drag it as in some pipe wrenches ; therefore it is not
crushed. For the same
reason the Atlas pipe
wrench can not lock
on the pipe as the grip-
ping point; being in
advance of the handle,
it is impossible for it
to lock.
The wrench is de-
signed to be just as
effective when fully ex-
tended as when used
on the smaller size of
pipe. The movable
jaw, as represented in
the illustration, is in slot marked No. 3 for the
larger sizes ; by shifting to slot marked No. 2 the
wrench can be used on the medium sizes of pipe ; and,
shifted to slot marked No. 1, can be used on the
smaller sizes. For examples, on the 18-inch wrench,
slot No. 1 for i to 1-inch pipe, slot No. 2 for 1} to
lHnch pipe, slot No. 3 for 2-inch pipe. The mov-
able jaw, as the illustration also shows, is not a screw
jaw, and is designed to have no weak parts. There
are no nuts on the wrench to jam and no delicate
parts to get out of order or break. It is made of
special wrench steel, drop-forged, every wrench

GRAHAM COUNTY.
A meeting of the shareholders of the
Arizona Copper Co., Limited, wa9 held in
Edinburgh, Scotland, on the 4th inst., to
hear a statement from Supt. Colquhoun.
The chairman said the meeting was held
in accordance with a promise made some
time ago that they should have an oppor-
tunity of meeting Supt. Colquhoun while
he was in that country. Supt. Colquhoun
and other employes of the company at
Clifton had purchased largely of the
shares of the company, but were surprised
that while they were successfully working
and making lots of money for the share-
holders, the latter were giving so much
attention to litigation, which they in Ari-
zona did not see was to be of any profit.
After describing in detail the various
mines and works at Clifton, Supt. Colqu-
houn said that during the past four years
the development and increase of plant had
revolutionized their business methods. He
had solved the problem of making low-
grade ores a valuable asset, and they had
found they could make money from them.
Their plant had been strained to the ut-
most, and had gone more and more out of
date. During the present half year they
had not been doing nearly as well as six
months ago, and they did not do as well
six months ago as the previous six months.
They had been suffering from a tremen-
dous congestion of business, but they had
relieved the situation considerably. They
should have to bear on the problem the
bost appliances that now could be had.
The important thing was not now what it
cost, but could they make copper when
copper went back in price to its old value'?
They had no right to expect that they,
copper men alone, should benefit by the
prosperity which everyone enjoyed all
over the world at the present time. Could
they, when these hard times came again,
from these 4% ores, make copper at as
low a price as they did formerly ? To that
he answered, yes ; provided they made
the improvements in the works to which
he was about to refer. They had decided
to erect a 200-ton concentrating plant, and
they would be able to raise their output
to somewhat over 13,000 tons of copper
per annum. They had decided to expend
£150,000 in rebuilding their smelting plant,
their concentrating plant, in increasing
the capacity of their railway and their
Bessemer plant, and so put them in a con-
dition they required to be in to handle
these low-grade ores. A vote of thanks
was tendered Supt. Colquhoun for his
services to the company.

C. C. Harker, president Western Car-
bonic Acid Gas Co., owner of the magne-
site property east of Porterville, will put
in a furnace for roasting the ore. The
deposit is 90% pure. When roasted it
makes an oxide of magnesia and gives off
carbonic acid gas, which is liquefied, trans-
ferred to steel and shipped for carbonat-
ing mineral waters, refrigerating pur-
poses, etc. The oxide of magnesia is used
in the paper mills, after being treated with
9ulphur gas, making sulphide of mag-
nesia, used, after being pulverized to a
fine powder, to take out the resinous mat-
ter in the wood pulp used in the manu-
facture of paper. The oxide is also used
for the manufacture of magnesia bricks.
The company also uses it for making light
carbonate of magnesia. A demand is
made for it by the powder companies for
their high-grade powder, it acting as an
absorbent of the nitro-glycerine.

A. H. Elftman says: "The ore in
the Tourist vein carries sulphides of iron,
copper and lead, carrying gold and silver,
and usually associated with a quartz
gangue. From the ore so far found in
place and the abundant float it appears
that there will be rich pay streaks, com-
posed entirely of the sulphides, besides
large bodies of quartz ore carrying these
sulphides, more or less evenly distributed.
This latter will form the low-grade or
concentrating ore. From the ore on the
dump and that taken from the bottom of
the Tourist shaft it is shown that this ore
is a good concentrating material, running
about $10 per ton, according to assays
made, and concentrates about ten tons of
ore into one ton of concentrates."

OURAY COUNTY.
(Special Correspondence). — The Camp
Bird mill of forty stamps, twenty Frue
vanners and four Wilfley tables, which
crushes an average of 138 tons of ore per
day, has operated every day during the
past year, with the exception of a close-
down on Christmas and on the Fourth of
July — both cases being purely a holiday
affair. From 61% to 62% of the mill sav-
ing is effected by amalgamation, the bal-
ance being saved in the concentrates. It
is figured that at least 90% of all the
valueB in the ore is extracted by the two
processes.
There are various devices about the mill
which have been designed by those in
charge, as the outgrowth of the require-
ments of everyday practice. One is the
system of quick-traps below the plates for
the purpose of arresting any amalgam
which might otherwise escape. Another
consists of gravity and hydraulic sizersby
which the material passing from the plates
is classified for the different concentrating
tables. The vanners are ranged in two
rows, the first taking the material from
the plates through the system of sizers ;
the tailings from the first row are elevated
to another system of sizers, or classifiers,
from which they pass down to the second
row of vannei's. The entire concentrate
product is elevated and carried to a sepa-
rate building and there dumped into
V-shaped bins, containing coil3 of steam
pipe, connected with the boilers, and by
this arrangement the concentrates are
slowly dried, after which they are dropped
down through chutes to the floor where
they are sacked for shipment. It is
pointed out that this method of drying
avoids the loss which may take place
when the concentrates are dried rapidly
by fire heat, which is often sufficient to
produce fumes and a loss therein.
For the purpose of effecting a saving of
values in the concentrator tailings, a
cyanide plant has been erected, which will
doubtless be in operation within thirty
days. In this plant there are virtually
four floors. On the top floor are the so-
lution storage and mixing tanks ; on the
third floor are the leaching tanks which
first receive the pulp and wherein a weak
solution of cyanide is applied ; from these
the material passes to tanks immediately
beneath on the second floor, where it is
subjected to the strong solution. From
the last named tank the refuse is sluiced
down to oblong tanks on the first floor,
where we also find the zinc precipitating
boxes. In the basement are the tanks
into which are drawn the exhaust solu-
tion, and where it is brought up to the re-
quired strength for use again. Here is
also the bullion furnace.
The tanks are all of steel, the main
leaching tank being 22 feet diameter by 6
feet depth. The plant will have a capac-
ity of 100 tons per day ; 600 tons of mate-
rial will be constantly in course of treat-
ment through the plant. It is estimated
by Supt. W. H. Coates that the concen-
trate tailings, resulting from present ca-
pacity of operating, will be equal to the
capacity of the cyanide department,
although there is a large tonnage of tail-
ings impounded on the premises.
The main mill building is being ex-
tended to make room for forty additional
stamps, twenty of which to be put in this
fall and the others next spring. This will
also require additional concentratoi's. At
this mill I observe the use of a new stamp
die, made in two sections, with a flange on
lower section to hold the upper part in
place. The design of the die is that the
upper section may wear out and be re-
placed without replacing the entire piece.
It is claimed that it works satisfactorily.
The 2-mile tramway line has forty-six
buckets, and from the 11,500 feet altitude
at the mine down to the mill is a descent
of 1500 feet. The Camp Bird ores are a
sulphide of iron, carrying gold values in
the main, though much of the gold is in

(Special Correspondence). — The Silver
Link mine, situate in Poughkeepsie gulch,
four miles from Ouray, is being put in
condition to produce by its owners and is
in charge of F. O. Seabury. This prop-
erty was considerable of a producer about
ten years ago, yielding copper in a bornite
and chalcopyrite ore. For several months
past the work has been directed to clean-
ing out and retimbering the old workings
and it is expected that the mine will be in
position to ship copper ore within a few
weeks.
Ouray, Sept. 7.
(Special Correspondence). — The Bach-
elor mine, near Ouray, is producing nearly
5000 tons of ore per month. The high-
grade smelting ore, amounting to about
150 tons per month, runs from 180 to 200
ounces in silver, with small values in gold.
The bulk of the output, classified as mill
ore, averages about forty-five ounces sil-
ver. The highest grade milled runs about
100 ounces and the lowest about ten
ounces silver. The mill, in charge of
Supt. C. E. Fryberger, is strictly a con-
centrator and is an illustration of how the
details of concentration are usually
worked out according to the needs that
develop as the ore handled is experi-
mented with. In this case the ore passes
through an 11x15 inch Dodge crusher,
thence elevated to a storage bin, below
which is an automatic device which feeds
the ore to a revolving four-mesh screen,
the coarse from the latter passing to a set
of 14x27-inch four-mesh rolls; that which
passes the screen goes to a set of 6x30-
inch, twenty-mesh, high-speed rolls. The
product from the twenty-mesh rolls is
elevated to different sets of wet screens,
the coarse screenings passing to three
Bartlett tables; and the fine to two other
Bartletts and one Cammett table. The
tailings from the coarse tables are ele-
vated to and reground by a set of 6x30-
inch rolls, the product passing through a
wet twenty-mesh screen and thence to the
group of fine tables. The coarse concen-
trates carry about 30% lead, high values
in silver: the fine carries about 10% lead
and nearly the same proportion of silver
as the coarse. The crude ore contains
about 6% of zinc, a pretty thorough sepa-
ration of which is made from the silver
and lead by the tables, the zinc passing to
the tailings. The final tailings from all
the tables are then carried to hydraulic
gravity sizers. by which the waste ma-
terial passes down through the bottom;
the slimes overflowing and running to
canvas tables below. Over each set of
canvas tables is a second hydraulic sizer
which receives the slimes at the top and
fresh water from below, which causes the
slimes to overflow at the top though
spouts and thence over the tables. The
saving thus effected on slime tables
amounts to considerable. It is estimated
that the entire mill saving is about 80%.
The concentrates contain a considerable
amount of gray copper in connection with

The ores from the Bachelor are brought
out through a 700-foot crosscut tunnel,
containing double track for ore cars, a
pipe line for compressed air and a steam
pipe from the boilers at the tunnel en-
trance to the large hoisting engine at the
breast of the tunnel, where it taps the
vein. At this point a 7xll-foot shaft sinks
300-feet by the side of the vein, there be-
ing drifts from the shaft on the vein at
100 and 200-foot stations. From the tun-
nel level an upraise connects with the
third level 260 feet above, where there is
1300 feet of drifting on the vein; from the
third level a 90-foot upraise connects with
the second level, where there is also a
large amount of drifting. The vein is
pretty well stoped out between the second
and third levels. Most of the present ton-
nage comes upon the tunnel level and the
one above it, or the third.
The vein, which ranges from 8 inches to
8 feet wide, follows the trend of a great
porphyry dyke. The formation is such
as requires very little timbering. The
shaft mentioned goes beyond water level
and it requires a sinking pump. It is
sunk on the line between the Bachelor
and Khedive grounds. The tunnel men-
tioned belongs to the Khedive property.
Geo. R. Hurlburt, who owns the Khedive,
is president of the Bachelor Co.; so that
the two mines, which endline with each
other, work in harmony. The Khedive
is at present doing development work.
Tim Marrion is Supt. of the Bachelor
mine.
The Caliope and Dexter groups are now
owned by the Caliope-Dexter M. Co., of
which C. H. Nix is manager and S. R.
Hopkins secretary. The company is sink-
ing a shaft at a point between the Caliope
and Dexter veins, having already sunk
150 feet and are to sink 150 feet deeper.
Crosscuts are being made from the shaft
to the two veins It is said the purpose is
to build a tramway from the mine to the
river and erect a mill at the latter place.

SAN JUAN COUNTY.
(Special Correspondence). — The Her-
cules Con. M. Co., under the management
of Thos. H. Kane, is operating on the Sil-
verton side of Sultan mountain, on a group
of thirty-two claims. The workings con-
sist of an upper tunnel which crosscuts the
formation, and is now in 1700 feet. About
600 feet below it is a lower crosscut tunnel
which penetrates the mountain a distance
of 2400 feet. The two tunnels cut five par-
allel veins, which stand nearly vertical,
and on which a large amount of drifting
has been done, the upper and lower tun-
nel workings being connected. From the
upper tunnel entrance a tramcar line, 1000
feet long, carries the ore down to the mill
at the foot of the mountain. The ore
passes through crushers and rolls, and
from the latter are elevated to revolving
screens, from which the different sizes pass
to a system of jigs. About 65% of the
values are saved in the jig product ; the
tailings from the jigs pass down through
automatic feeders to four batteries of
stamps, below which are amalgamating
plates, the tailings flowing down to Wilfley
tables. The mill is operated by two low-
case Leffel water wheels, propelled by
water from a 3400-foot flume from Mineral
creek. The mill, which has a capacity of
120 tons, is just starting up. The ores
consist of a copper and iron sulphide, car-
rying values in gold, silver and lead.
The Iowa mill, of which R. J. McCart-
ney is superintendent, is handling 160 tons
of ore per day, which is carried to the mill
from the Iowa mine in Silver Lake basin,
over a lj-mite tramway. The ore goes
through crushers and rolls, from which it
is elevated to screens, passing from the
latter to jigs of 2 to 8-mesh. The jig
product contains about 70% of the values
saved. The jig tailings are run through
Huntington mills, thence over concentra-
tors— five Wilfleys and one Cammett. A
Chilian mill is being put in to do a work
similar to that of tho Huntingtons ; also
four new Cammett tables are to be put in.
A system of hydraulic sizers, designed by
Manager Watson of the Iowa, are to be
put in use over the concentrators. The
table tailings are carried to a system of
canvas tables, which are in charge of N.
H. Crane, who looks after this part of the
product on a percentage of values saved.
Supt. McCartney has designed and put
into use a riffle attachment to the concen-
trators, which he believes effects an im-
portant saving. He is also using an auto-
matic sampler for the table tailings and
one of different design for the crude ore
that passes the revolving screens — both of
his own design. The Iowa concentrates
are transported from the mill to the rail-
road track, a distance of 1 mile, where
there are shipping bins. The Iowa mill is
operated by steam. Wascott.
Silverton, Sept. 8.
(Special Correspondence). — The mana-
ger of the Silver Lake mines has com-
menced the construction of a new mill at
the railroad, where the ore bins and lower
terminal of the tramway line are located.
This point is about 2£ miles from the
mines and approximately 2000 feet lower.
A branch tramway line has been erected
from the mouth of the Unity tunnel, con-
necting with the central terminal on the
main line, and is 4300 feet long, the high-
est tower on this branch being 107 feet
high. This new line was constructed by
Wm. Dusedau of New York. The Unity
tunnel starts on the western slope of the
mountain, proceeds easterly through the
mountain, cutting about 400 feet under
the main Silver Lake workings, with which
it connects by an underground shaft. The
tunnel is reported to be about 2 miles in
length. No doubt all ore below the level
of the old workings will be passed down to
the Unity tunnel and thence down to the
new mill, rather than hoisting it to the
upper levels and sending it to the old mill.
It is understood that the old mill, which is
up in Silver Lake basin, will still be oper-
ated on certain ores even after the comple-
tion of the new mill.
A new steam power plant, belonging to
the Silver Lake property, has been built
on the Animas, which is designed to oper-
ate additional generators for electric
power.

SAN MIGUEL COUNTY.
(Special Correspondence). — The Four
Metals M. Co., composed of Boston, St.
Louis and Pueblo parties, is operating the
Palmyra mine, in Turkey Creek basin,
between Telluride and Ophir. The hold-
ings comprise about seventy acres and de-
velopments consist of a tunnel 1500 feet
long, which goes in on the vein, with con-
siderable amount of stoping above the
tunnel level. The ore is a partially oxi-
dized quartz, carrying gold, silver, copper
and lead values, a considerable tonnage of
which is exposed in the workings and
piled up on the dump. For some time dur-
ing the summer four cars of ore a week
were shipped to the smelters, which, it is
asserted, averaged $40 per ton. A tram-
way line is being erected from the mine to
the foot of the mountain, where a mill
will doubtless be erected next year.

tem of burlaps connected with the sluices,
however, has worked well, and ground
that pays 10 cents to the cubic yard can
be profitably worked.

HOUGHTON COUNTY.
At the Calumet & Hecla the shaft has
six compartments, each of which is as
large as an ordinary shaft, one for the
ladderways and the sixth for the wires
and pipes which are necessary for the tele-
phones, light, power, water and com-
pressed air. The remarkable feature of
this great mine is that the course of the
vein is so undeviating that the engineers
can plan work ahead for thousands of
feet with the absolute certainly that the
actual workings will agree with the plans.
As a result the underground workings are
laid out with mathematical accuracy. The
great pumps that hoist thousands of gal-
lons of water every hour are operated in-
terchangeably by compressed air and
electricity. There are 300 power drills
constantly in operation, each of them do-
ing the work of six men, operated by com-
pressed air, and these are kept at work
night and day. Every drift is constantly
under the eye of the engineer in his office
on the surface, and the result of every
shot is known as soon as the smoke clears
away. Every ton of ore hoisted is auto-
matically registered in the office, and the
condition of the entire mine at any given
moment is but a matter of a few minutes'
calculation and a few inquiries by tele-
phone. The air supply of the mine is
good; blowing engines send it down to
the bottom of the shaft, where it is caught
by fans and carried through pipes into
the headings of the drifts.

Following is the annual report of the
Supt. Homestake M. Co.:
J. B. Haggin, Esq., Pres. Homestake
M. Co., San Francisco, Cal. — During the
fiscal year just closed operations at the
works were attended with little or no de-
lay. Repairs, made necessary by the or-
dinary wear and tear to the plant at large,
have been well kept up, while the com-
pany's shops for taking care of its ma-
chinery have been greatly enlarged and
much improved.
By consolidation, there has been ac-
quired the Highland mine, with its 130-
stamp mill and very fine hoist; the Black
Hills & Fort Pierre Railroad, used for
hauling wood, coal, mining timbers, etc.,
to the works; and the water, water rights,
Humes, ditches, etc., of the Black Hills
Canal & Water Co., while, by purchase, a
considerable area of adjoining ground has
been added to the property of the com-
pany. The important, extensive and ex-
pensive betterments to the property,
which have been under construction for
some months past, will soon be finished,
when the increase of the company's net
revenue to follow will begin — I mean the
cyanide plant with a capacity of 1200 tons
daily to treat the tailings from the mills
and a water system to increase the present
deficient supply.
The Ellison hoist has been sunk from
the 500 to the 600 level, the B. & M. shaft
from the 800 to the 1000 level, the Golden
Prospect shaft from the 500 to the 600
level and the Golden Star shaft from the
900 to the 1100 level. The ore develop-
ment at the greater depths attained are
very encouraging, and insure a long life to
the mine.

It is not necessary that the settler should
go over the land after the hour of open-
ing. But the President's proclamation
warning "sooners" against making set-

According to the report of Supt. R. R.
Hedley, the cost per ton of ore of smelting
to matte for the year ending September
30, 1899, Hall Mines smelter, was reduced
from $3.66 in the previous year to $2.96,
as follows : Flux, $0,196 ; fuel, $1.445 ; la-
bor, $1.32. The matte averaged 45% cop-
per, 290 ozs. silver, 0.77 oz. gold per ton.
The silver loss amounted to 42,838 ozs.,
the total amount charged being 532,837
ozs. The ore averaged 2.49% copper ; the
yield was 2.34%, 90,000 pounds of copper
being lost in the slags. One of the rever-
beratory furnaces was lengthened and re-
paired. It was found that the brick bot-
tom was extremely thin, in places but 2.5
inches of the original 9 inches remaining.
After twenty days' work smelting base
metallics, with poor results, it was deemed
advisable to tear out this bottom, finding
therein, after careful sampling, about
twenty-five tons of copper, 20,000 ozs. sil-
ver and 400 ozs. of gold.

tons of ore in sight that can be treated.
I informed our smelter Supt., Mr.
Hodges, a year ago, that we must mine,
ship and treat $5 ore at a profit. Reason-
able handling charges when fully equipped,
little economies here and there and other
factors will accomplish this. We expect
to install an 80-drill plant in the near fu-

worked by a system of pillars, taking out
good ore and leaving poor ore as pillars.
The output is about 250 tons per day,
which the smelter converts into base bul-
lion, shipped and refined in Omaha. They
have also a matte smelter, in which they
are smelting copper ores from a copper
deposit in San Lorenzo, and from which
they are turning out a matte containing
50% copper, smelting approximately ten
tons to one. Lime for the smelter is se-
cured close at hand, iron from Durango,
silica from San Lorenzo. C. Wilhelmi is
general manager, M. Dahlgren mining
superintendent, Wm. Daly smelter super-
intendent. Wages for miners range from
75 cents to $1.50, Mexican, per eight-hour
day; laborers 75 cents, Mexican.
The output of silver and lead in the
Parral district was $4,000,000 value last
year. There are fifteen mines in opera-
tion. The output of ore in the Parral dis-
trict is 20,000 tons a month. Labor is
cheap. Mexican miners who are good
workmen are paid $1 a day of their own
money. " Boss " Shepherd is still operat-
ing in Chihuahua, and is driving a 3-
mile tunnel.
RUSSIA.
Vice Consul General Hanauer says:
There are but four works in the Ural re-
gion of Russia where gold is obtained by
means of chemical process. The former
gold mines, having given out, are not
worked any more. While the world's an-
nual gold production has increased 16.3%
during the last decade, that of Russia has
remained as before, amounting to about
2400 poods (86,668 pounds) yearly. But
platinum, of which the Ural mountains
furnish 95% of all the world's supply, has
increased both in quantity and value. The
amount of this metal produced in the
Ural region in 1899 was 13,242 pounds, as
against but 6365 pounds in .1890.
THE KLONDIKE.
According to the latest information
from the Gold Commissioner at Dawson,
royalty will be paid this season on $16,-
000,000. Reports from Stewart river, 200
miles distant, has caused another exodus
to that river.
Wages on the hillside claims at Dawson
have been reduced to $4 per day and
board for underground miners and $3.50
per day and board for top men. A few
individual owners are still paying the old
scale of $5 per day and board, or 80 cents
per hour. About 1200 men are affected.
They claim the wages paid are not in pro-
portion to other expenses and talk of or-
ganizing a miners' union to enforce the old
rate.

Books Received.
Missouri Geological Survey, No. 13,
1900, quarto, 250 pages. This work may
attract attention among geologists be-
cause of the extraordinary nature of its
contents. Its author, the State Geologist
of Missouri, seems to have thought that'
his ideas about things mundane and spir-
itual were important enough to be pub-
lished at public expense, and there accord-
ingly appears a jumble of stuff that might
read all right at the close of the eight-
eenth century, but sounds somewhat
archaic in these sunset months of the
nineteenth century. One paragraph — the
third on page 23 — is quoted : "In the
glorious interior of our blessed Motor, the
Sun, dwells the Vicegerent of the true
God. That his celestial realm is the logi-
cal rendezvous for the spritual product of
the Earth, is shown by the fact that the
first essential element of organic life is
paid out by the Sun. And inasmuch as
that productive energy cannot persist

without a facility of renewal, the ultimate
synthetic product of Earth, the Spiritual
energy evolved by Afterthought, has no
other logical destination than the serene
and equable interior of our Sun." That
kind of thing may be what Missouri wants,
but it sounds funny in a report signed
by a State Geologist and issued by the
State.

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co.'s Scien-
tific Press TJ. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Baling Press.— No. 657,287. Sept. 4,
1900. C. J. Johnson, Paso Robles, Cal.
This invention relates to that class of
baling presses known as " horizontal con-
tinuous presses." The object is to pro-
vide a means by which the opening and
closing of the doors, and the various
operations of the machine are performed
mechanically, and hand labor is reduced.
It consists of a frame having the press-box
mounted at one end, a revoluble cam-
carrying disk at the opposite end, a fol-
lower and a rebounding plunger beam
having a slotted extension from one end
adapted to guide said beam in its move-
ments, said beam actuated by the cams so
that the follower is reciprocated within
the box. There is an extension through
which the compressed material is forced
to form the bale, this extension having a
movable top plate and screws by which
the outer end of the plate is adjusted to
regulate the size of the discharge opening
and determine the amount of compression
of the baled material. The material is
charged into the press through a top and
a side door so hinged as to open outwardly
from each other and by means of oscillat-
ing shafts, rocker arms and a rotable disk,
with means engaging these arms, the
doors are automatically opened and closed,
being retained in their closed position by
spring-pressed latch bolts.
Lubricator. — No. 657,219. Sept. 4,
1900. Byron Jackson, San Francisco, Cal.
This invention relates to an apparatus by
which bearings of any description are con-
stantly and automatically lubricated. A
flange or collar is secured to a revoluble
shaft and formed with a cup having a
rounded interior and one end opened, a
second cup surrounding the shaft has a
bearing formed rigid therewith and enter-
ing the opening end of the first named
cup, but without contacting therewith.
This bearing has a passage through it,
and an annular loose cover for the second
cup through which the shaft passes. A
bent tube has its open end lying close to
the inner wall of the first-named cup so
that the revolution causes the oil to be
taken up by this tube, carried from one
cup into the other, whence it is allowed to
pass into the bearing around the shaft.
Automatic Adjustment for Har-
vester Reels. — No. 657,229. Sept. 4,
1900. S. M. Warder, Winters, Cal. This
invention relates to a means for adjusting
the reels of harvesters, headers and the
like apparatus so that the reel will always
be in the proper position to sweep the
grain toward the sickle whether the straw
be short or long. It consists of means
carried by the header portion of the har-
vesting apparatus by which the sickle bar
is raised or depressed, a reel adapted to
sweep the grain toward the sickle bar,
reel timbers to the front ends of which
the reel shaft is journaled, links support-
ing said reel timbers at the rear and at
points intermediate between the reel and
front end of the bars in such a manner
that the bars carrying the reel frame are
tilted about their pivot points so as to
move the reel frame upward and forward,
or downward and backward in unison with
the movements of the header frame.
Carbureters for Explosive En-
gines.—No. 657,738. Sept. 11, 1900.
Henry L. Jessen, Watsonville, Cal. This
invention relates to improvements in ex-
plosive engines and generators by which
the gas or vapor used in such engines is
produced, and it is intended particularly
to provide for a constant and complete
vaporization of a hydrocarbon liquid, a
mixture of air with the vapor thus pro-
duced to make it explosive, and a means
for regulating the flow by which it is sup-
plied only when the engine is in operation.
The invention comprises in an explosive
engine, a horizontally journaled revoluble
generator, with means for advancing the
liquid therethrough, and means for heat-
ing the same, an open pipe connection be-
tween the discharge end of the generator
and the inlet valve of the engine whereby
a vacuum is produced in the generator by
the movement of the engine piston, a pipe
and trap connection between the opposite
end of the cylinder and the supply tank
whereby the hydrocarbon liquid is drawn
into the generator when the engine piston
produces a vacuum and the supply is cut
off when the inlet valve of the engine has
not opened or the engine is at rest.
Raisin Cleaner and Cap Stemmer.
—No. 657,692. Sept. 11, 1900. Harry
Eastwood, Fresno, Cal. This invention
relates to an apparatus designed for clean-
ing raisins and for performing work known
as "cap-stemming." It comprises re-
voluble drums having partially inclosing
segmental fenders, flexible spring-pi'essed
aprons capable of elastic yield at any point
and between which and the drums fruit is
caused to pass, means for delivering the
fruit into said space near the upper part
of the drum, a tailboard or screen over
which the fruit is passed from the drums,
and an air-forcing blast mechanism by
which the refuse is separated from the
fruit.
Metal Lath Attachment and Sup-
port.—No. 657,827. Sept. 11, 1900. Wm.
McCall, San Francisco, Cal. This inven-
tion relates to a means for securing and
supporting metal lathing, such as is em-
ployed in the construction of fireproof and
other buildings. It comprises a support-
ing base formed of plates or strips of sheet
metal having slits cut upon the sides to
form tongues with one end remaining at-
tached to the strip. These strips extend
over the lower flanges of the I-beams,
and .have one or both edges turned at
right angles with the vertical depth of the
strips, and transverse connections having
ends passed through the strips and locked
thereto by twisting or bending.
Traveling Harvester.— No. 657,700,
Sept. 11, 1900. Benjamin Holt, Stockton,
Cal. The object of this invention is to
enable a traveling harvester and thresher
to be used on side hills and maintain the
frame of the thresher and cleaner in an
approximately horizontal position by rais-
ing the wheels on one side and lowering
the wheels on the other side with relation
to the thresher frame, so that while the
wheels travel indifferent horizontal planes
upon the inclined surface of the ground,
the threshing machine frame will be main-
tained in the desired position. In con-
junction with these movable wheels there
are mechanisms by which the up and
down movement of the wheels effected sim-
ultaneously. It comprises a main frame
with supplemental frames in which the
bearing wheels are journaled upon op-
posite sides of the machine. A rack bar
is guided and slidable transversely with
relation to the main frame, with a mechan-
ism by which the rack bar is movable in
either direction. Chains connected with
the bar extend outwardly in opposite
directions and there are guide pulleys
around which the chains pass, standards
carried by the wheel frames to which the
outer ends of the chains are connected,
anti-frictional rollers or slides carried by
the movable wheel frames, and fixed
guides against which they are movable.

CROWN GOLD MILLING CO.
Manufacturers of the "CROWN" CONCENTRATOR and CROWN
ORE SIZER. A dry process of sizing and concentrating ore, sand or
gravel. Designed to accord fully with the laws of specific gravity,
and especially adapted to refractory ore or localities where there is
no water.
The chief claims for the Crown Concentrator are that it occupies
less floor space and has nearly four times the capacity of any wet
concentrator; that it will concentrate ores containing base and refrac-
tory metals that ordinarily slime and carry off values; that it effects
a saving of values far above the ordinary methods of concentration.
Joshua Hendy Machine Works,
San Francisco, Cal.
Office and Salesroom 38 to 44 Fremont Street.
Works Cort. Bay, Kearny and Francisco Streets.
We have, now in operation, a complete plant
for crushing, sizing and concentrating ores by the
Crown Dry Milling Process.
Mine owners desiring tests made can forward
us, freight prepaid, not less than 1000 lbs. nor
more than 4000 lbs. of sample, for which a
charge of $20 will be made. (This amount in-
cludes assaying, etc.)
Ores for which this process is adapted and of
which consignments are solicited are any con-
centratable ores, pulps, tailings, or sands, carry-
ing sufficient values, whether they have hereto-
fore been profitably concentrated or not.

THE GRIFFIN
THREE ROLLER
7VYI
The Griffin Throe Roller Ore Mill is a simp.y constructed Mill, suitable for working all kinds of ores that
require uniformly fine crushing by the wet process. This Mill is a modification of the well-known Chilian
Mill, but the rollers run upon a crushing ring or die, which is inclined inwardly at an angle of about 30 degrees,
tho rollers themselves also being inclined to the central shaft of the Mill, thus utilizing the centrifugal force,
as well as tho weight of the rollers themselves as a crushing agent. The Griffin Three Roller Ore Mill is there-
fore a Mill of great strength, and has few wearing parts. We construct these Mills with extreme care, using
only tho best of raw materials, which are most carefully worked by men who are specialists as mill builders.
We sell the Griffin Ore Mill on its determined merits, and will gladly supply full information regarding it to
any one.

FOUR and SIX-FOOT FRUE VANNERS
\A/itn Brownell "Patent Lip" Flange Belts.
STANDARD MACHINE OF THE WORLD.
When a Concentrator like the Frue Vanner lias been on the market nearly two decades, and the sales have constantly
Increased, it is safe to say it is the " Standard Machine of the World." More Frue Vanncrs have been sold during the last
twelve months than for the same period at any time during the history of the machine. Practical mining men in all parts of
the world where mining is carried on will testify as to its merits. It is the " standard" which all competitors are trying to
imitate.
The results obtained by this machine are the " acme" of concentration, and several cheap and untried machines that
have lately come on the market compare by it. The manufacturers will tell you that they are "just as good, and
cheaper," etc. The facts are that no other concentrator made has an equal capacity, or will yield as clean a concentrate
with as small loss in the tailings as the Frue Vanner. The amount saved from the lower first cost of an inferior machine
counts little in the year's results, when compared with the increased output from a Frue. This machine not only gives bet-
ter results at both ends of the belt (i. e., clean product and poor tailings), but is operated at less expense and requires less
attention than any other machine on the market. At the Alaska-Treadwell mine, where they have ordered over 350 Frue
Vanners, one man attends 48 machines for 13-hour shift.

High Explosives.
In the issues of June 23, 30, July 7, 14 appeared a
series of articles ou high explosives which gave con-
siderable detail regarding their use, manufacture
and properties.
The chief explosives in use are nitro-glycerine, gun
cotton, dynamites consisting of nitro-glycerine com-
bined in various proportions with various bases,
blasting gelatine, explosive gelatines and gelatine
dynamites consisting of various combinations of nitro-
glycerine and gun cotton, with a mixture of niter,
cellulose and soda. Besides these is the Spren-
gel group of explosives, which consists of two
practically inert substances, which, upon being
mixed, produce powerful explosives. One of these
substances is usually a hydrocarbon. An infinite
variety of explosives of this class has been produced.
Whenever an announcement is made of a new high
explosive, insensitive and powerful, with secret .in-
gredients, one is likely to be correct in the assump-
tion that it is of the Sprengel group. Among the
better known of these are the following : Rack-a-
Rock — chlorate of potash and a liquid hydrocarbon
(dead oil). Bellite — ammonium nitrate, nitro-benzole
and niter. Roburite — ammonium nitrate with chlo-
rinated di-nitro benzole. Hellofite — naphthaline,
phenol, or benzine in fuming nitric acid. Securite —
meta di-nitro benzole with nitrate of ammonia or
niter.
The composition of a sufficient number of this class
of explosives has been given to indicate the variety
of constituents which can be used in making high ex-
plosives of this group. They are all insensitive and
require a powerful initial explosion to educe their
full power. Those having nitrate of ammonium are
likely to be objectionable and not of advantage in
submarine work and places where water is present,
owing to the hygroscopic quality of that salt, which
tends to deliquesce, unless well protected from moist-
ure. Two recent explosives, of secret composition,
marsite and thorite, probably belong to this class.
It is thought that the latter may be usefully em-
ployed for torpedo shells, but it is as yet a question
whether it can be completely exploded when in large
charges, so as to give an explosion of the first order.
The picric acid class of explosives has attracted
attention, more because
of public notoriety
than of intrinsic merit.
Among these are:
Melinite, for which the
French have claimed so
much, and lyddite, used
by the English in the
South African war.
These are both essen-
tially the same, con-
sisting chiefly of picric
acid combined with nitro-
cellulose, and in some
cases with cresilite, a
coal tar product. Em-
mensite, another of the
picric acid class, was
experimented with, but
has recently disappeared
from sight.
The relative power of
explosives is difficult to
estimate, and authorities
differ regarding it, for
there is a notable differ-
ence in the results obtainable, depending on
the physical conditions attendant upon the place-
ment of the explosive and the means and method
of the initial explosion. Some confinement of tamp-
ing is essential. The difference in the results secured
between an explosion in the open and when covered,
however slightly, is great, and is to be borne in mind by
those using explosives for industrial purposes. The
same amount or degree of tamping is not necessary
for the high explosives as for gunpowder, and much
needless and dangerous work might be avoided were
due consideration given to this point of difference.
The following table is given as showing the relative
force of the various high explosives, submarine work
excepted, gunpowder being taken as one : Gunpow-
der 1, gun cotton 5.5, nitro-glycerine 12, explosive
gelatine 14, blasting gelatine 16, dynamite (No. 1) 10,
bellite (Sprengel) 6, roburite (Sprengel) 3, melinite 3,
lyddite 3.
There is nothing definite nor positive about such
comparative tables. A writer in an English tech-
Sampling and Reduction Works, Republic, Wash.— See Page 372.
New Mexico Placer Syndicate's Experimental Dredger.— See Page 372, "Catching Black Sand.
nical journal on the same subject gives the following
table : Gunpowder 1, nitro-glycerine 4, dynamite 5,
gun cotton 5, explosive gelatine 6. The difference
between the two tables is noticeable. All such com-
parisons must be accepted as rough approximations,
since the same explosive under apparently similar
conditions gives discordant results, for exact meas-
ures of the forces developed by explosives are im-
possible.
Experience and observation show that the energy
of a high explosive depends considerably upon the
character of the detonation by which the main explo-
sion is secured, and one ounce of gunpowder, even
when strongly confined, exploded in contact with gun
cotton only iuflames it, while ten grains of confined
fulminate of mercury produces full explosion of the
gun cotton. That the energy of explosion depends
upon the nature and force of the initial explosion is
probably true of all explosives, including gun cotton.
A too low initial explosion will simply produce a
rapid burning, instead of a detonation of the ex-
plosive. High explosives are subject to sympathetic
explosions ; that is, explosions of detached quantities
of the material through the detonation of adja-
cent explosions. The effect of all explosives
is increased by their being surrounded with a
resisting medium. There are some singular phe-
nomena noted in connection with explosions. One
noticeable incident is cited in connection with the
cutting of the Chicago drainage canal. The final
bottom in a rock cut about 16 feet deep was being
made by the removal of a depth of cutting of about 6
feet. The material was a close-grained limestone.
By the use of a channeling machine the rock to be
removed had been previously cut off vertically from
the sides of the excavation. The face of the rock to
be removed was nearly vertical. A row of holes
quite near together had been drilled in a straight
line across the cut, parallel with and about 6 feet
back of the face. After the holes were loaded with
dynamite they were simultaneously fired by electric-
ity, throwing off a mass of rock back to the line of
holes. After the blast, examination showed a plainly
defined crack extending entirely across the cut,
nearly parallel with and about 6 feet back of the line
of holes which had been fired.

Up to 1850 the United States was a nation of poor
men. Mining began to put out great increase of nat-
ural wealth, and the national prosperity is directly
and indirectly due to such output and mineral devel-
opment. Mining has done a great deal for the nation,
but the nation has done very little, comparatively,
for the mining industry.
It is recommended by thoughtful miners that it
would be a needed additional safeguard against fire
were a small building away from the main mine plant
to be provided for a pump house. Of late several
fires have been noted in mine plants that caught close
to the pump, and with such suggested arrangement
in case of fire connection could be made surer, with
increased chance of saving the buildings.
The difference between theory and condition is ex-
emplified by the approved suggestion throughout
British Columbia that the provincial tax on metal
ores be made differential ; that is, practically, that
the tax be doubled in the case of ores sent out of the
province for treatment, the idea being to encourage
local smelters, which, in the main, is a good plan, but
under existing conditions in British Columbia is not
to be given serious consideration.
When accumulated debris from the wash of the
land occasioned by the development of the country
and mining operations since 1849 covered some land
along the Yuba and Feather rivers, Cal., it was
loudly claimed that as a resultant the land was not
worth 10 cents a square league. Now when the Gov-
ernment wants 3500 acres of this land to build dams
and restraining barriers, this "worthless" land is
held at figures up to $100 per acre.
Tesla has so injured his prestige by premature and
impracticable assertions that his announcements in
the field of electrical discovery do not attract the at-
tention they formerly commanded. His latest claim
is to have successfully overcome the cause of electro-
lysis, and he has an invention designed to prevent the
escape of electricity from a wire. He claims that he
can insulate the wire by passing through it or near it
air kept at a low temperature, producing a coat of
ice on the wire which cannot be broken through by
the strongest currents, and at the same time gives
an insulation that costs practically nothing. By
means of this the loss of electricity or electrical
energy in transmission, it is claimed, can be rendered
so small as to be insignificant, and power can be
transmitted to great distances by means of under-
ground wires. So far it is only a claim, but on a sub-
ject of surpassing interest to the electrical world.
The "Scrip" Decision.
That nothing is ever settled until it is settled right
is again shown by the decision this week at Los
Angeles, Cal., by Judge Boss in the U. S. Circuit
Court in the case known as "the scrippers' suit," in-
volving the right of "scrippers " to file upon oil land
as agricultural land prior to the discovery of oil
thereon. Judge Ross rules squarely against the
scrippers. His former decision was based largely on
legal technicalities and the letter of the law. Last
Monday's ruling is based as largely on equity and the
spirit of the law. In his decision he reviews the affi-
davits made by the scrippers that the lands filed
upon by them were not mineral or claimed for mining
purposes, and that their application therefor was not
made for the purpose of fraudulently obtaining title to
mineral land, but with the object of obtaining the
same for agricultural purposes, and declares these
affidavits to be manifestly false, holding that had the
applicants stated that they wanted them for that
purpose, and desired to select them under the law
authorizing agricultural lauds to be taken in ex-
change for lands situated within a forest reservation
surrendered to the Government, the officers of the
local land office would doubtless have refused to file
or receive the selection of such land under the forest
lieu land Act.
It is to be noticed that Judge Ross has injected an
element of common sense into his ruling, where he
holds that the " scrippers " could legally file only on
lands " vacant and open to settlement," going on to
exempt public land containing mines "of any min-
eral " from such locatable area. The cause of the
bona fide prospector and miner has been aided by
Judge Ross's decision.
The complainants had alleged the non-mineral affi-
davits were not required by law, but Judge Ross
declares the fact remains that such affidavits were
made and constituted a representation and one of the
means by which the selectors sought to secure the
lands, and, having been made for the purpose of
evading and defeating the law, his court will not lend
its aid toward securing the fruits of the fraud.
The statute under which the scrippers filed is a
plain standing offer on the part of the Government to
exchange any of its lands that are vacant and open
to settlement for a like quantity of similar land
within a forest reservation, for which it had pre-
viously issued a patent or to which an unperfected
bona fide claim had been acquired.
In all cases the land authorized to be selected in
lieu of that relinquished is required to be vacant and
open to settlement. Vacant public land is open to
settlement only when it contains no known salines or
mines, whether of gold, silver, petroleum or any other
mineral.
It is, to say the least, doubtful if any persons
authorized to select vacant lands only are author-
ized to select lands in the actual bona fide occu-
pancy of others under the settlement laws or under
a mining location, even though the location be invalid
by the absence of a valid discovery of mineral.
Whether the lands in controversy should be classed
as mineral or agricultural is a question for the de-
termination of the Government. The lands in con-
troversy were surveyed by the Government in 1854
and returned as agricultural, but Secretary of the
Interior Teller, in a communication to the General
Land Office, speaks at large of the notations of sur-
veyors, saying they are prima facie evidence only of
the character of lands and subject to rebuttal by sat-
isfactory proof of the real character of the land ;
and the determination of the real character of land is
subject to revision by the Commissioner of the Gen-
eral Land Office, and an appeal from him by the Sec-
retary of the Interior. And the rule to be adopted
is that they will be considered agricultural or mineral
according as they are more valuable in the one class
or the other.
In view of the late increase in the development of
California's oil wealth, the matter is of considerable
importance. Judge Ross's decision checks and re-
bukes the wholesale effort to absorb the territory in
question by perversion of what was intended to be a
just and salutary law. The decision is favorable to
the miner and commands respect.
In accordance with its usual custom of going into
detail in all things affecting the mining interests, this
paper in the earlier part of the present year pub-
lished a complete exposition of the subject — ' ' Scrip,
and the Law of Title to Oil Lands" — which ran
through the issues of April 7, 14 and 21, and gave the
whole subject fullest and fairest discussion.
The lands in question have been withdrawn from
public entry by the General Land Office; a U. S.
judge has checked their spoliation. It is now in
order for the real developers of the mineral wealth,
the petroleum miners of California, to have suitable
congressional action next winter. Nothing but
alteration of the present law governing that subject,
by the national legislature, will insure permanent re-
lief from attempts at similar encroachment.
Under date of Aug. 31st the U. S. Commission to
the Paris Exposition of 1900 takes pleasure in inform-
ing the Mining and Scientific Press that, in accord-
ance with the official announcement of the awards at
the Paris Exposition, this paper is "entitled to use
the award of grand prize." While, of course, the
Mining and Scientific Press expected an award of
some kind of "grand prize" at the Paris Exposi-
tion, yet, without desiring to detract in the slightest
from courteous appreciation of the honor accorded
this paper at Paris, it is not as highly valued as was
the prize awarded to the Mining and Scientific
Press by the World's Columbian Commission on the
occasion of the World's Fair at Chicago, when a spe-
cial award was made to this paper — the only one of
the kind accorded to any journal exhibiting there, the
award being in the official language of the Commis-
sion: " For the general reliability of its news and the
clear and intelligent editorials therein. * * * *
Favorably known for the fullness and accuracy of its
weekly reports of the progress of mining." Prob-
ably when fuller reports come from Paris as to the
manner of award, it may be that in the case of the
Mining and Scientific Press the World's Fair at
Paris has been as complimentary in its reference to
this paper as was its predecessor at Chicago.
On page 378 is an item from Cripple Creek, Colo.,
regarding the stealing of valuable ore by miners em-
ployed in the Elkton mine, which constitutes a very
good advertisement for the mine in question, and re-
calls an unauthenticated statement regarding the sale
of a mine in Shasta Co. , Cal. , some years ago, which
was not of itself a gilt-edge proposition, but was be-
ing worked in the hope of possible profit resulting
from development. In some way the story got out
that the mine was being systematically robbed of ore
by men in its employ, and one of the first things told
to a prospective purchaser, brought there by the
owner, was how shamefully the latter was being
robbed, being too easy a man for such smart ore
thieves as his superintendent employed. The sale of
the mine was quickly made, and the stories regarding
the alleged ore thieves as quickly ceased, there being
apparently no further reason for their continuance.
Looking through some old files of this paper and
reading therein accounts of building and installation
of mining and metallurgical plants that in their day
were up to date, it is noticeable how archaic and far
off it all seems now, though then they were consid-
ered quite the thing ; and the thought naturally
comes, when, in 1920, the present issues of this paper
are looked into as dusty files of twenty years past,
will the modern appliances now described seem so
obsolescent as those of 1870 and 1880 seem now ?
The contrast emphasizes the advance and progress
in mining and metallurgy.
An interesting case comes up this week before the
U. S. District Court for the northern district of Cali-
fornia, being an application of the Government for
an injunction to restrain the Mountain Copper Co. at
Keswick from causing sulphur fumes or requiring
it to put in some device to condense them. This
course is taken to institute a suit for alleged dam-
age to vegetation in the vicinity of the works. Such
suit has long been threatened, and the matter might
as well be made the subject of judicial determination
now as any time.
In January, 1898, in a magnificent way, was cele-
brated in San Francisco the fiftieth anniversary of
the discovery of gold in California, and the event had
commemoration commensurate with its importance.
It was largely a celebration of the hydraulic mining
of gold. In the present year occurs the fiftieth anni-
versary of quartz gold mining in California, a form of
the gold mining industry that has not reached in
California its fullest development and that will inure
to the State's prosperity in a permanent and endur-
ing manner.

for lead produced during 1900.
Chemically pure zinc does not decompose water to
any appreciable extent; commercial zinc is violently at-
tacked by even slightly acidulated water.
The Arizona law authorizing the recording of mining
claims with the recorder of the county in which the
claim is situated, went into effect July 1, 1895.
Mercury will evaporate at any temperature above
42° F. Its low specific heat— .033° F.— is" what makes it
so extremely sensitive to changes of temperature.
It is ultimately more satisfactory to have the ore
valued by the smelter than by the assay returns, where
quantity is more important than simple specimens.
The Rand gold production has all along been given in
crude ounces, as the gold comes from the plates or vats.
United States gold production is given in ounces fine.
The Government fee for the filing of certificates of im-
provements prior to the giving of Crown grants on min-
ing claims in British Columbia has been raised from $10
to $25.
A change of temperature from 5° F. to — 20° F. will
cause a 30-foot 85-pound railway rail to contract .1 inch ;
a change from 5° F. to 70° F. will cause it to expand
,',-inch.
A "miners' inch " is equivalent to one-fortieth of a
cubic foot of water per second. It takes 4 miners' inches
at 100 feet pressure to obtain 1 H. P. ; that is, 6 cubic feet
per minute.
One per cent carbonic oxide in air is liable to occa-
sion death if inhaled. Gunpowder explosion and under-
ground ignition of fuel produces this gas with insufficient
ventilation.
With fairly good water it takes years to scale a boiler,
but once scaled it will scale every three months or so, as
the skin of the iron is gone. Kerosene or caustic soda
is not recommended.
Gasoline engines are made that supply power at
one-tenth of a gallon of gasoline per H. P. per hour.
They are economical motors in any country, and inval-
uable where water is scarce.
Explosives are only comparatively safe so long as
they are treated as dangerous. To put this into practice
is to approximately insure immunity from accident ; to
neglect it is to court disaster.
No right can be initiated on government land which
is in the actual possession of another by a forcible, fraudu-
lent or clandestine entry thereon for the purpose of lo-
cating it as a mining or other claim.
A CUBIC foot of lead ore weighs 674 pounds.
Thus a vein of galena, 1 foot wide, 6 feet high and 6 feet
long (a fathom) will produce 16,582 pounds, or a vein 1J
inches wide will net one ton to the fathom.
So far as known the Belgian Government is the only
one having an official rule that when men are being
hoisted or lowered in a mine shaft a capable assistant is
required to stand by the engineer to replace him in case
of sudden indisposition.
Careful sizing of pulp from batteries before sending
it onto a concentrating machine gives good results. It
is not reasonable to expect to save coarse and fine sul-
phurets on a single belt or table with an equal volume of
water and the same grade.
While it is not necessary that a locator should be the
first discoverer of mineral upon the land, in order that a
prior discovery by another shall inure to his benefit, and
give validity to his location, it must have been known to
and adopted and claimed by him.
Where a locator of a mining claim on government
land fraudulently antedates his notice of location for the
purpose of defeating an actual locator thereon, such loca-
tion is fraudulent as against such rightful claimant, and
it is also fraudulent as against the Government.
Any journal published anywhere, any time can refuse
to publish any advertisement and is not obliged to give
its reasons. Probably the journal mentioned correctly
concluded there was a certain style of patronage that it
could not afford to take, considering the interests of its
readers.
In September, 1899, Cripple Creek, Colo., mine divi-
dends aggregated $733,500; it is thought that the
dividonds for the current month will aggregate double
that amount. In 1899 Cripple Creek mines paid a total
of $4,354, 402 in dividends. The 1900 total is estimated at
$7,000,000.
Electrical underground concentration sounds at-
tractive, and the idea is not to be condemned, but it
would take great and expensive experimental work to
demonstrate its economy. The one insuperable objec-
tion would seem to be the entailed watering and unwater-
ing of the property.
Corrosive action of mine water on iron pipe is fre-
quent. In some cases, as at the Stanley mine, Idaho
Springs, Colo., the corrosion of the iron is attributed to
the copper and ferric sulphate. In the case cited after a
trial of iron, load, copper, bronze and wood pipe, the lat-
ter was found most satisfactory.
The plans of the Comstock Pumping Association are
understood to mean even more than the mere unwater-
ing of the flooded levels, which work is going steadily
on. It is conceived that sinking the Osbiston or Com-
bination shaft to a depth of 5000 feet would demonstrate
the existence of large ore bodies at that depth.
In smelting electrically, "black lead" or plumbago
crucibles are used, the pot standing on a heavy copper
plate connected to one pole of the dynamo, another cop-
per plate acting as a cover for the pot and to which the
other pole of the dynamo is attached. The heating of
the charge is by radiation, as in a muffle furnace.
All money orders may be cashed at any money order
office at which they may be presented, irrespective of
the office on which they are drawn. In all cases the
owner must be identified. At the office on which a
money order is drawn the order must be cashed as soon
as it is presented, even if the advice has not yet arrived.
All explosives containing nitro-glycerine freeze at a
comparatively high temperature, are generally in a
frozen state, and must be thawed before they can be of
any use. How to make a simple and effective thawer has
been repeatedly published herein. The Hendrie & Bol-
thoff Mfg. Co., Denver, Colo., make an excellent thawing
device.
A cement for a crack in an iron tank is made as fol-
lows ; Five parts brimstone, two parts black lead, two
parts sifted cast iron filings; melt together (taking care
that the brimstone does not catch fire); have the crack
absolutely dry ; heat the damaged part with a red-hot
piece of iron ; heat the cement in a melting ladle till soft;
then apply.
The Supreme Court of the United States, in the case
of Chambers et al. vs. Harrington (III U. S., 310) held
"that when adjoining claims to mineral lands are held in
common work for the benefit of all done upon one of
them in a given year to the amount required to be done
upon all in that year meets the requirements of Sec. 2324,
United States Revised Statutes."
Platinum ore is a complex body, consisting of the
metal in combination with varying proportions of other
members of the platinum group, iridium, rhodium, pal-
ladium, ruthenium, osmium, with from 4% to 20% iron.
Russia is the only country where platinum ore is mined.
The Pacific coast platinum is found in alluvial deposits,
generally associated with osmoiridium.
Probably the best way to settle this whole public
land question, including corporate absorption of the
mineral area of California and other States, is for the
Federal Government to turn all the public lands over to
the States in which they are situated. Federal admin-
istration of public lands in this west half of America has
rarely been right and has often approximated to fraud.
The usual method of removing mill scale from forg-
ings and plates is to place the iron in a solution contain-
ing one part of hydrochloric or sulphuric acids to ten
parts of water, for from four to twenty hours. An elec-
trical process with varying success is to use a solution of
sulphate of soda, the plates to be cleaned forming a
negative electrode and an iron plate the positive elec-
trode.
Agricultural patents obtained between 1866 and
1872 were granted subject to the condition of the extra-
lateral right attached to an apex in adjoining mineral
land. The right of the holder of a valid lode location to
follow the dip of the vein into adjoining agricultural
land has been passed on adversely by a U. S. circuit
judge, but the question has never been decided by the
U. S. Supreme Court.
It is not unlikely that resumption of work in the
South African mines will see successful effort to put in
practice the proposition to sink to a depth of 8000 feet.
Relay winding stations, electricity, the ingenuity of the
American mining engineer, and the maker of American
mining machinery will furnish successful solution to the
problem, though it involve new questions in ventilation,
pumping and hoisting.
Petroleum refuse has been successfully solidified
for use as fuel. In one process about 10% of soda lye,
with 10% fatty matter, is treated in a boiler, and enough
petroleum refuse added to the heated mass to make 100
parts. This mixture is heated under constant stirring
for one hour. The temperature is kept just under the
boiling point of petroleum. In this incipient stage of
saponification the mass acquires the property of taking
up large quantities of oil. The mixture is run into
moulds, cooled and cut into any desired form.
To PUT a California mining location on record so as to
protect the locator, in case of jumping, since the law of
1897 was repealed, in the absence of a local- mining dis-
trict and a recorder (as prior to the law of 1897), the Civil
Code of California, Section 1,159, provides that all notices
relating to mining claims may be filed with the county
recorder, which will give the public due notice. A plain
preliminary notice on a claim and recording, as stated,
should give the locator protection.
Like all other accomplishments of modern civilization,
machine tools in their present form are the result of a
process of slow development; a machine does not spring
full-fledged into being, but is gradually differentiated
from the original type, gaining here and there a useful
member and losing here and there a superfluous one.
Many of our modern machines illustrate "the survival
of the fittest " and adaptation to environment, changed
and modified by a thousand years of trial.
Galena introduced into a bath of molten anhydrous
zinc chloride results in a double decomposition with the
formation of zinc sulphide and lead chloride, any silver
present being contained in the latter. Metallic zinc added
to the melt will result in the formation of argentiferous
lead, with the regeneration of a fresh quantity of zinc
chloride. An alternate method consists in the leaching
out of the zinc chloride and silver by water, leaving
chloride of lead behind, which is ultimately to be recov-
ered.
The Supreme Court of California has decided that
"an appropriation of water by means of a ditch is not
measured by the capacity of the ditch, but is limited to
such quantity, not exceeding its capacity, as the appro-
priator may put to a useful purpose ; and no matter how
great in extent the original quantity appropriated may
have been, any amount less than the whole amount ap-
propriated which has not been devoted to a beneficial
use within five years is lost and forfeited as against a
subsequent appropriator thereof."
It has long been noted by millmen that amalgam con-
tains more gold in winter than in summer. This has
been ascribed to the warmer water in summer, making
the amalgam more fluid; amalgam retorting 40% in
summer may retort 45% in winter. Experiment does not
conclusively demonstrate that there is a temperature at
which the affinity of quicksilver for gold is at a maxi-
mum, but experiment does seem to show that in battery
amalgamation there is a greater saving of fine gold at a
temperature of 50° F. battery water than at a tempera-
ture of 60° or 70°.
A " laid " ROPE consists of a core composed of a
strand of either hemp or wire, around which are twisted
six strands, each containing a similar core covered with
six individual wires. A "formed" rope comprises six
strands laid around a core as explained above, but each
strand containing a larger number of component wires.
Around the six strands above mentioned a further out-
side layer of twelve is laid, thus making eighteen strands
in all, independent of the core. A " cable laid " rope
consists of "laid" ropes closed together to form one
cable, as in the ordinary hemp roping.
A mining blacksmith and tool sharpener says : I
used to temper drills to bore diorite. I half filled a bucket
with clean water and spilled about a half a pint or more
(if it was plentiful) of muriatic acid into it and mixed it
thoroughly. I then warmed the drills just red, cooled
them up about f-inch and let them come down to a straw
color. I have seen a drill bore several inches tempered
in this way, where half an inch would dull it if tempered
in the ordinary way. It will help the boring consider-
ably if camphorated turpentine is used instead of water
to keep the bore wet. Camphorated turpentine is made
by dissolving camphor gum in turpentine.
There are three ways of converting oxygen into
ozone. If a stick of phosphorus be left in a closed bottle
half filled with water for several days ozone will be found
in the enclosed air. This is the chemical method. If a
solution of sulphuric acid in water be electrolyzed with
platinum or gold electrodes, ozone will be found at the
surface of the anode. This is the electrolytic method.
If electricity at high potential be discharged through
air ozone will be produced. This is the electrostatic
method. Whenever a f fictional electrical machine is
worked small quantities of ozone are evolved. It is pro-
duced for industrial purposes chiefly by the electro-
static method.
IN emery the abrasive material is crystallized alumi-
num oxide ; in carborundum it is carbide of silicon. Al-
though carborundum is much harder, its crystalline
structure is less favorable for grinding than is emery.
The crystals of carborundum are long and narrow, with
few cutting edges and smooth faces, while emery crys-
tals are nearly cubical and have rough surfaces. Per-
haps the greater hardness of carborundum is offset by
the better cutting properties of the emery. This is also
indicated by the difficulty in keeping carborundum
wheels from glazing when too much slag is used in mak-
ing them. Emery has the advantage over carborundum
for grinding or polishing purposes in all cases except
where the finest grades are used. For the latter carbo-
rundum seems to be better.

Republic Sampling and Reduction
Works.
Written lor the Mining and Scientific Press bj D. Jacklinq.
The accompanying illustration* shows in a general
way the design and arrangement of the sampling
and reduction works of the Republic Consolidated
Gold Mining Company, at Republic, Washington,
which are now nearing completion.
The small building in the center foreground is the
machine shop ; the small building on the right is the
assay office and laboratory, and the one on the left
the storehouse. The main artery of the mine, No. 4
tunnel, runs under the right hand end of the mill.
The mouth of it may be seen between the machine
shop and assay office. A connection has been made,
however, back about 100 feet, turning at right
angles, and coming to the surface near the right
hand side of the sampler, under the tramway from
sampler to main mill. There are two other tunnels
tapping the vein, at depths of 200 feet and 380 feet,
respectively, the dump from the lower one of which is
seen in the right hand background.
The plant is designed to handle 200 tons daily, and
for several months after starting will draw its sup-
ply of ore entirely from the Republic mine, in order to
absorb a large quantity of ore already mined and on
the dumps, as well as an accumulation of tailings of
several thousand tons from the old mill. When these
accumulations have been used up, the works will
take, in addition to the output of the Republic mine,
sufficient custom business on the ores offered by other
mines in the district to make up its full capacity, and
provision has been made for easy enlargement of the
plant to keep pace with increasing custom business
and to accommodate all offerings. The plant is near
the mouth of No. 4 tunnel, which is the principal
opening to the Republic mine, tapping the vein at
right angles to its strike at a depth of 600 feet, with
a total length of 2500 feet. The sampling mill was
located with a view to convenience for receiving ore
from the No. 4 tunnel of the Republic mine, and from
the mines in the upper part of the district by means
of a surface gravity tramway, which will be built for
that purpose by the time the mill is ready to receive
custom ores. There is no suitable site for the large
mill below the sampling mill, and it being located
above, necessitates hoisting the crushed and sampled
ores to the main crude ore storage, which is done by
a self-dumping skip running on an inclined track, and
operated by a small friction hoist located on the
sampler, where its operator can also load the skip
from a bin, under which the skipway terminates.
The sampler is designed to handle 200 tons ore in ten
hours, and will only be run on day shift until the mill
capacity is increased. The storage bins will accom-
modate 600 tons of unsampled and a like amount of
sampled ore — 1200 tons in all. From the upper
storage bins the ore is charged direct into a No. 5,
style D, Gates crusher, passing which it is elevated
to a revolving trommel, through which the fines pass
direct to a set of 15x36 Gates high-grade rolls. The
rejections from the screen return to a style H, Gates
crusher, and to the screen again by way of the same
elevator until it is fine enough to pass the screen to
the rolls. Under the rolls, the first sample is taken
by a Brunton sampler, the rejections going by eleva-
tor and shoots to either of the six lower storage bins.
The sample is elevated to a small set of rolls and
further crushed, after which it passes in succession
two more automatic samplers, the rejections going to
the storage bins, and the final sample to a small sam-
ple hopper in the adjacent sampling room. This sample
is about 1% of the total ore crushed, and is further
reduced to proper bulk by hand sampling, after
necessary additional crushing and grinding. The
sampling mill machinery will reduce all the ore pass-
ing through it to not coarser than J-inch mesh, and
this is done in order to avoid any coarse crushing
machinery or roughing rolls in the main mill. The
process to be employed in the mill is essentially fine,
dry crushing, roasting, cyaniding with certain modi-
fication in detail, and precipitation with zinc dust.
From the main storage bins the ore passes by gravity
through two 26x5-foot revolving driers, to two sets
15x36 rolls, and thence to two sets 15x26, and is ele-
vated by two elevators to a system of fine screens,
consisting of three 8-foot by 48-inch hexagonal
screens, and three 6x8-foot Jeffrey Columbian sepa-
rators. The fines pass direct to storage bin over
roasting furnaces, and the rejections to three 6x8-
foot ball pulverizers, and from them again over the
screens until required fineness is reached. The roast-
ing plant consists of three straight-line furnaces,
having a hearth area of 100x12 feet and a capacity of
about seventy-five tons each. The ore falls from the
400-ton fine ore bins by gravity into the furnace feed-
ers, and after being roasted "dead," is automatically
cooled and discharged from them into a 300-ton
storage bin above the leaching tanks. .
The leaching and precipitating plant contains
sixteen steel leaching tanks, 22 feet square by
6£ feet deep; two gold solution tanks, 14 feet diameter
by 10 feet deep; one sump tank, 24 feet diameter by
5 feet deep; two precipitation tanks, 10 feet diameter
* See front pase.
by 8 feet deep, and three fresh solution and standard-
izing tanks, 14 feet diameter by 10 feet deep. All
tanks are steel. The last mentioned three are located
on a platform 12 feet above tops of leaching
tanks, and all the other round tanks in the precipi-
tating section, adjacent to the leaching room, but on
a lower level. The precipitating section also contains
four 24x36-inch section, all iron Johnson filter presses
for collection of product; two Root rotary solution
pumps, a triplex vacuum pump, and small engine to
drive the whole. Leaching tanks are loaded by
means of side-dumping basket cars running on two
parallel tracks over each row of tanks. Tailings are
discharged either by sluicing or shoveling into cars
through four openings in the bottom of each tank.
Steam power is used throughout, and the steam plant
is located adjacent to the fine-crushing section of the
main mill, and consists of six 60-inch by 16-foot return
tubular boilers, having a combined capacity of about
500 H. P. The sampling mill, roasting machinery,
precipitation department, machine shops and fine
crushing department are driven by a separate engine
for each. The main engine room, between the boiler
house and fine crushing section, contains, besides the
180 H. P. Corliss for driving the fine crushing machin-
ery and driers, a compressor for the mine and a 30
H. P. generator for lighting purposes. Each depart-
ment was made independent in its motive power, both
for convenience in operation at present and in order
that electric power, which is contemplated for the
near future, might be readily applied. Wood is used
for fuel, both for steaming and roasting purposes.
The mill will be equipped with dust exhausting and
collecting appliances where needed to keep it as free
from ore dust as possible. The extreme dimensions
of the sampler are 96x63 feet and of the mill 315x280
feet. The gases pass away from the furnaces through
435 feet of brick flue, 8 feet square, to a steel stack 8
8 feet in diameter and 112 feet high, A fully equipped
machine shop has been provided, as well as com-
modious blacksmith shops, assay office and laboratory,
and storehouse. All the buildings are frame, the
sampler and mill having corrugated iron roofs.
■•
Blast Furnace Smelting.
The reduction effected in lead ore smelting is due to
carbonic oxide, incandescent carbon, and, under cer-
tain circumstances, to iron, sulphur, and metallic sul-
phides. By far the most important of the reducing
agents is the carbonic oxide, the action of which is
modified by various factors, such as the interior shape
of the blast furnace, its temperature, the blast pres-
sure and volume, the tuyere area, the size and condi-
tion of the charge, etc. All these are sufficiently im-
portant to merit consideration. The reduction of
carbonic oxide (carbon monoxide) consists in its power
of robbing oxygen from a metallic oxide, thereby con
verting itself into carbonic acid (carbon dioxide), and
the metallic oxide into metal. As carbonic acid be-
gins to dissociate at 1200° C, the reducing power of
carbonate oxide can be active only at a lower tem-
perature, such as exists at a certain height above the
bosh or tuyere zone. The location of this height natu-
rally depends on the interior shape of the furnace. If
the bosh is contracted, the blast and the charge are
there more concentrated, and accordingly a thicker
layer of incandescent fuel is maintained between the
unmelted charge and the molten slag. The carbonic
acid, generated by the fierce combustion in front of
the tuyeres, in the presence of an excess of oxygen,
has to pass through this layer of glowing carbon,
which, rapidly absorbing oxygen, converts the di-
oxide into monoxide. As the bosh contraction is
passed and the area of the furnace is increased, the
gases rise more slowly, and the carbonic oxide has
plenty of time to absorb oxygen from the ore, oxidiz-
ing itself back into dioxide, and reducing the metals.
On the other hand, the reverse takes place when
there is no bosh contraction, but the furnace sides
are kept straight. In this case both blast energy and
charge are diffused over a wider area, consequently
the layer of incandescent fuel through which the car-
bon dioxide ascends is thinner, less of the gas is con-
verted into carbonic oxide, and the reducing action
is, therefore, decreased. Tuyere area also affects
the formation of carbonic oxide. Small tuyeres admit
thin streams of air that are rapidly absorbed by the
glowing coke with the evolution of carbonic oxide ;
large tuyeres, on the other hand, deliver more oxy-
gen than can be absorbed by the fuel, and the gas
formed is almost entirely carbonic acid, which mostly
passes through the furnace as such. In the one case,'
therefore, the furnace atmosphere is reducing ; in the
other it is oxidizing. A third factor is the strength
of the blast. A strong blast favors reduction, be-
cause the air pressure, forcing the carbonic acid
formed in the tuyere zone into intimate contact with
particles of the incandescent fuel above, even to the
center of the charge, forms the maximum amount of
carbonic oxide or reducing agent. A weak blast, on
the contrary, does not penetrate so closely to the
center of the charge, nor insure such intimate con-
tact ; and, in consequence, less carbonic oxide is gen-
erated. In connection with the strong blasts, it
should be remarked that their use necessitates a
greater height of ore column, respectively furnace
shaft, otherwise there will be a waste of fuel by the
escape of overheated gases, still capable of doing dry-
ing and roasting work in the furnace. The other de-
termining agent is the quantity and fineness of the
ore. Small charges favor better mixing of the ore
and fuel, and therefore the more intimate action of
the reducing gas on the charge. Fine ore, also, by
impeding the draught, causes the carbonic oxide to
more thoroughly permeate the charge in its efforts to
escape, and so to remain longer in contact with the
ore. Both causes tend to promote reduction. — C. C.
LONGBRIDGE.
Catching Black Sand.*
Written for the Mining and Scientific Press by Jno. D. King.
Noticing some questions in the Mining and Scien-
tific Press of May 19, 1900, in regard to the saving
of black sand and extracting the gold held therein,
stirs interest in that class of work, as I have kept a
vigilant search for several years for all that is being
done in this line.
The river dredger placer machines offer better
facilities for saving the gold-bearing silica and black
sand than other placer machines, on account of their
compactness, quantity of dirt handled and nature of
their machinery. As so many dredging plants are
not a paying investment, it would be well to look into
the concentration of these sands, for, when some
cheap and efficient means of saving the values they
contain is found, no doubt many otherwise valueless
placers will be dividend-paying propositions.
In 1898-99 I was dredge-master for the New Mex-
ico Placer Syndicate on the Chama river, in Rio Ar-
riba county, N. M., where an experimental dredger
was built, and many tests were made with various
devices for saving the values of the river placers of
that district. Ordinary sluice-boxes with different
designed riffles, and loaded with quicksilver, were
first tried with no success; failure revealed the fact
that the bright-looking gold was covered with a
transparent siliceous coating, making the particles
look twice their actual size. Forty assays were then
made from the river material, ranging from the sur-
face to 20 feet in depth, giving an average of 40%
free gold, 40% in combination with the silica and 20%
in combination with the black sand. There was
1.158% black sand of the material as it came from
the buckets; and extracting it with magnets was
tried with the result that only the magnetic iron was
caught, and assays from this showed but a slight
trace of gold.
The amalgamation idea was discarded and the boxes
were provided with cocoa matting, expanded metal
and devices with undercurrents. These gave little
satisfaction, as the interstices would quickly fill up,
letting the values run over and causing too frequent
shut-downs.
All who are experimenting in this class of mining
seem to be working in the same channel, viz., to save
the black sand by a single operation — that is, by
dumping the whole mass into a box, sluicing off the
coarse material and saving the valuable silica and
black sand as in washing gold; but I find, the gravity
of the silica too near that of the black sand to allow
of such rough work. The Chama river people have
been carrying on experiments in this line with under-
current devices for the past ten months. The result
is they find they must use screens, which, by sizing
to one-fourteenth of an inch, will take off four-fifths
of the material as it comes from the buckets, giving
their machines much lighter work. By leaving their
concentrates run 70% to 80% of the reddish silica, so
manifest in the Chama, and which is the silica that
carries the gold, they obtain a concentrate assaying
from $35 to $60 per ton. While engaged with them,
I built a revolving burlap concentrator that worked
well; the interstices would catch the reddish silica,
black sand and fine gold, and, as it revolved, the con-
centrates were washed into a hopper, leaving the
burlap clear to be filled anew as it came in contact
with the sluicing material. As before stated, they
were looking for a device to do away with screening,
which would condemn that class of machinery, as it
could not handle such a vast amount of material; be-
sides, the large boulders would not let it do good
work and would knock it out quickly. Therefore, it
was set aside to make room for other experiments.
Where screens can be used, I do not know of another
machine so efficient as one with a revolving burlap.
I once tried bumping tables to bring a 6% black sand
concentrate to 60% and found they were too slow and
took up too much space to adapt them to placer work,
as were also devices that required stopping and clean-
ing up every few hours.
As all placers have a peculiarity of their own, and
necessary smelter facilities for treating the concen-
trates vary with locality, a slight modification may
be required; but, in general, screening the material
as fine as practical through a series of revolving
screens, and running the fine material over one or
more revolving burlap machines, according to amount
handled and fineness required, to be determined by
values in the silica and smelter facilities, is (from
what data I can collect from the experiments of
others and those of my own) the best arrangement
for extracting the gold-bearing silica and black sand
of the placers.

The Metallurgy of Zinc.
Written for the Mining ani> Scientific Pbbss
by Dit. J. Onr.v.
There is no field of metallurgy so disheartening or
disappointing from an economic point of view as the
manufacture of zinc from its ores, considering the loss
involved and the cumbrous and tedious mode of its
production. In fact, the manufacture of zinc has
preserved the same status, as to the principle under-
lying its production, which it held at the time of
Albertus Magnus, (Albert von Bollstaedt), the great
"Doctor Universalis," of whom contemporanean
chroniclers of the thirteenth centurj' report conclu-
sively the following opinion : " It is generally ad-
mitted that Albertus was a God-fearing man of great
erudition, and it is clearly proven that he never
offended the dictates of the Church, or stood in
league with the devil." Not so favorable was the
judgment bestowed upon the forerunner of the iatro-
chemical school, Theophrast Bombast, of the fifteenth
century, whose name seems to have lengthened with
the expanse of his reputation, and to have evolved at
the zenith of his glory into the title : Philuppus
Aureolus Theophrastus Bombastus Paracelsus of
Hohenheim, shortly known as Paracelsus in history.
It was this man Bombast who first introduced
the application of metallic salts like those of mercury
and copper, besides the dispensation of opiates, into
medicine, and pointed out distinctly the production of
zinc from its ores by the addition of charcoal and sub-
sequent distillation. Though acknowledged as the
precursor of the school mentioned above, he ranks
necessarily with the alchemists, since he claimed in
some of the passages of his writings to have discov-
ered that mysterious substance known as " the
philosopher's stone," and to have succeeded, merely
by fusing a small particle of it with metallic lead, in
transforming that base metal into shining aggregates
of precious gold. Charlatan that he was, like the
rest of his colleagues, he slyly kept a door open for
escape, and remarked in some of his later publications
that the preparation of the philosopher's stone, as
well as the substance itself, were illusions, and that
all those "adepts" who claimed to have compounded
the same were deceptive characters and mendacious
quacks.
To Paracelsus and his predecessor, Magnus,
then, we owe the method yet applied to-day in the
production of zinc, which has developed, after the
gradual introduction of a few improvements, consist-
ing in the greater number of vessels employed and
the enlargement of the furnaces used, into the follow-
ing modes of manufacture :
Of the processes known to have been worked on a
commercial scale, the English and the Carinthian
(Kaernthen, Austria,) methods — the latter a modi-
fication of the former — have been entirely abandoned.
They comprised mainly the utilization of vertical re-
torts of fireclay, and the reduction of the roasted ore
from the top to the bottom of the charge, under the
addition of non-caking carbon, which operation neces-
sitated an excessive consumption of fuel.
The Belgian and Silesian processes, however, rep-
resent " the survival of the fittest," and are serving
at the present time in the Joplin district of Missouri,
in Kansas, Indiana, and in Europe generally, for the
reduction of the ore to the metal. The main differ-
ence between these two systems consists in the shape
of the retorts, which have a cylindrical or elliptical
form in the Belgian process, while they are muffle-
shaped in the other. Since the height and length of
the retorts employed in the Silesian process is greater
than that of the vessels used in the Belgian system,
their width being nearly equal, the charges of zinc
oxide and carbon are necessarily greater in the first
case, so that the production of metal for a given
period is larger when operating the Silesian process
than the output resulting on the application of the
Belgian method. In recent years the tendency has
prevailed to increase the number of retorts employed,
which, in the Silesian process, are usually placed in a
single row in the furnace and in the Belgian in tiers,
so that a furnace receives nowadays a charge of six
to eight tons for a single operation. Thus the dis-
tillation furnaces, operated at Iola, in southeastern
Kansas, are generally elongated and double struc-
tures, fitted with 300 retorts on each side, which are
arranged in five rows of sixty each. On the other
hand, the furnaces at Cherry vale, Montgomery Co.,
Kan., situated also in the southeastern section of
that State, and those of Indiana (which are fired by
natural gas) contain 100 retorts per side, and are
arranged in five rows of twenty each.
The loss experienced in the two systems varies be-
tween 15% and even 30% of the metal originally
present in the ore, and it is generally assumed that
the loss incurred by the Belgian method amounts to
between 15% and 20% of the zinc, while the loss re-
sulting on applying the Silesian system is calculated
to be from 5% to 10% greater. This great loss in the
last case is accounted for by the circumstance that
poorer and more refractory ores are usually employed
in that process.
The retorts and tubes, which latter are required
for the purpose of joining the necks of the retorts
with the nozzles, are manufactured in place bymeans
of appropriate machinery, and the cost of their
preparation forms a considerable part of the ex-
penses incurred. The charging of these retorts re-
quires great skill, and so does the firing, which is
done either by the direct burning of coal or by gas,
while the workmen watch carefully the different
stages of the process. These are indicated by the
varying color of the flames and vapors, which are
gradually evolved, the first fumes given off being of a
brown coloration and consisting of the yellow oxide
of cadmium, accompanied by the appearance of the
latter metal itself; the next, the characteristic, very
intense bluish-white light of zinc vapors, which con-
tinues to show until the operation is completed.
The chemical reaction (I) involved in these opera-
tions appears to be very simple on paper, but great
care must be taken during its practical application
to maintain, by the proper addition of carbon, an
atmosphere of carbon monoxide, CO, in the retorts,
because else a secondary oxidation of the zinc formed
takes place in presence of carbon dioxide, COa, as
shown by the second equation :
I.— ZnO + C = Zn + CO.
II.— Zn + COa = ZnO 4- CO.
Cadmium, which is a constant associate of zinc in
its ores, accompanies the latter metal through all
the stages of preparation or reduction concerned,
and undergoes exactly the same reactions as zinc ;
but, being volatilized already near 865° C, while zinc
vaporizes only toward 1000° O, the former metal
makes its appearance first during the distillation
process described above.
The ores employed for the extraction of zinc are
almost exclusively zinc blende or zinc sulphide, gen-
erally known among miners as "black jack," and
smithonite or zinc carbonate, the latter being rather
rare, but readily reduced to' oxide by burning in
kilns, while blende requires careful roasting, so as to
avoid the formation of difficultly decomposable sul-
phate, the operation lasting between two and six
hours, according to the nature of the ore. It is
essential that the ores used for smelting be as rich as
possible, and also uniform in character, hence concen-
tration, mostly performed by Frue vanners, is con-
stantly resorted to. As the dressing works in the
Joplin district turn out concentrates averaging 60%
zinc, the value of the latter is readily calculated,
since this percentage is equivalent to 1200 pounds of
zinc per ton.
By the first of July of the present year zinc ore
was selling in Joplin at from $25 to $26 per ton, while
an ore of the same degree of concentration brought
$44 per ton a year ago, and $55 per ton in April,
1898. This low price of the ore was, however, not
caused by overproduction in the mining district, but
more so by the manipulation of the market. Since
the smelters are supposed to have driven down the
prices to the lowest point possible, and the contents
of the ore bins throughout the district have been
practically bought in, while but one-half of the mines
are producing at present, a rise of price has taken
place during the past month.
A remarkable fact which may have escaped ob-
servation generally is the circumstance that zinc sul-
phides, or sphalerites, carry sometimes high values
in silver, as the Mexican ores do, for instance, and
that it is worth while to have them tested for the
presence of this metal by the assayer.
It is quite evident that the only rational manner of
ascertaining the value of zinc ores must be based
upon their assay valuation, though it has been cus-
tomary at Joplin for a number of years to have these
values determined by inspection.. These inspections
were formerly made by men of much practical ex-
perience, generally natives of the district, who under-
stood to closely judge the values of the ore by daily
examining a handful of the product of the mills, com-
paring its appearance with that of the material of
former days and taking in consideration the locality
of the mines, besides the percentage reached by them
previously. At present the work of these inspectors
has been almost entirely replaced by the more reli-
able methods of the assayer, and the selling of the ore
is mostly proceeded with on this basis. The char-
acter of the ore as to admixtures of foreign constitu-
ents is, however, also considered, when fixing the
value of the ore, in a similar manner as is done with
manganese or tungsten ore, brought on the market,
for it is customary among the buyers at Joplin to de-
duct 50 cents per ton for each per cent of lead present
in the ore and $1 for each per cent of metallic iron
which the ore may contain above 1%. The smelting
charges, including transportation and cost of smelt-
ing, amount to $10.50 per ton of ore, so that the
present prices of $25 to $26 per ton leave a gross
margin of about $15 per ton to the smelter.
Presenting briefly the several methods now in op-
eration for the production of zinc from its ores, we
have :
First. — The Silesian process.
Second. — The Belgian process.
Both are objectionable on account of the loss in
metal occasioned by them, and the cumbersome
character of the utensils employed for the reduction
of the ore.
Third. — The electrolytic process, which has been
found to be impracticable and too expensive, in
spite of the numerous efforts made to improve it, so
that no economic process of that kind is in operation
at present.
Fourth. — The process proposed by the German
chemists, Dr. Dr. Lungwitz and Dr. Schupphaus, of
the Royal Polytechnic School of Berlin, whose scheme
consists mainly in the production of metallic zinc in a
blast furnace under a pressure of three atmospheres.
It is based upon the generally aoknowled principle
that the boiling point of a liquid or liquid metal is
lowered by the increase of pressure. The process is
to be regarded, however, as an experimental venture
only, as long as its practicability remains unproven
by an actual test on the large scale, and it must
necessarily appear that the maintenance of a pres-
sure exerted during the course of reduction of the
zinc oxide in a clumsy and voluminous structure like a
blast furnace is combined with quite extraordinary
difficulties.
Fifth. — The reduction process consisting in admix-
ing powdered aluminum to metallic oxides, and taking
advantage of the initial heat produced by the ignition
of a small quantity of a mixture of barium peroxide
and powdered aluminum, placed in proximity to the
former.
It has been found that the metals chromium and
manganese can be produced in almost chemically
pure condition and free from carbon in this manner,
though the costliness of the operation excludes it
from application in the manufacture of other less
valuable metals from their oxides, like zinc. The
author has also found by actual experiment that the
heat produced by the ignition of a small amount of
barium peroxide and powdered aluminum, when
placed upon an intimate mixture of zinc oxide and
pulverized aluminum, is not sufficient to induce the
reduction of the chemically pure oxide thus mixed
and made use of in his experiments, and that no re-
duction to metallic zinc takes place even when the
zinc oxide is mixed with both powdered aluminum and
barium peroxide in varying proportions. A trial to
reduce such zinc oxide, mixed with powdered char-
coal, under addition of a small quantity of aluminum
to start the reaction, by means of the heat obtain-
able in a muffle furnace used by assayers, gave also
negative results, so that no satisfactory prospect
lies in this direction.
Since neither of the practicable processes, enu-
merated above, give entire satisfaction, and, in fact,
all of them leave much to be desired, an improvement
of some kind would naturally be hailed with great ac-
clamation and appreciation. If we, however, con-
sider and examine the means at the disposal of the
metallurgist, it will soon be found that there remains
hardly another recourse than to resort to the ap-
plication of the electric current; and that, to all
probability, the solution of the problem will be best
accomplished by mixing the oxide of zinc, into which
form the ores of that metal are usually brought be-
fore treatment, with powdered charcoal, and sub-
jecting the mixture to the effect of the electric cur-
rent in a properly constructed furnace of large pro-
ducing capacity. In this manner, it seems to the
writer — and especially under the observation of the
necessary precautions in preventing the vaporization
of the metal by the addition of a protective layer of
a dense slag, fused beforehand, and the maintenance
of the lowest degree necessary to induce and sustain
the reducing action of the charcoal — that satisfactory
results may yet be in reach for the producer of zinc
on an economic plan.
The Etard Chlorination Process.
The claim of the Etard chlorination process to
public favor is the simplicity of preparation of the
solution. It is known in its application as the per-
manganate process. The solution consists of an ad-
mixture of certain quantities of hydrochloric acid and
permanganate of potash, or of sulphuric acid, salt
and permanganate of potash with water. The cost
of the solution when mixed in proportions for gold ex-
traction purposes is stated to be about li cents per
gallon. Its application is as follows: In a vat of any
shape or size with a depth of not less than 2 feet a
hole is bored through one side near the bottom. A
filter bed is laid down in the bottom, consisting of
coarse gravel, to a depth of about 3 inches; finer
gravel is spread over this and a layer of clean sand
on the top. Upon this filter is placed the roasted
ore to a depth of 1, 2 or 3 feet, according to whether
the fineness of the material will allow the solution to
pass through, or the depth of the vat will permit
such a thickness. The solution is then run onto or
poured on the ore and allowed to percolate through
it and the filter, then through the previously men-
tioned vent and into a second vat placed below the
outlet. This is allowed to go on for six hours, during
the latter part of which time the solution escaping
can, if possessing the characteristic color of the per-
manganate solution, be returned to the ore and al-
lowed to percolate a second time. To find when the
extraction is complete, a sample of the ore is taken
from the vat, washed with water, then shaken up
with some of the original solution and allowed to filter
through a filter paper into a test tube. To this is
added a little of a solution of sulphate of iron; and if,
after the red color of the permanganate disappears,
the liquid remains clear, the operation is complete;

September 29, 1906,
if a blue tinge follows the disappearance of the red,
there is still gold in the ore, and more solution must
be added to it. When the gold is all dissolved, the
remains of the solution still in the ore are washed out
by pouring water on the ore and allowing it to perco-
late through into the vat containing the gold solu-
tion. There are several methods by which chloride
of gold can be precipitated from the solution. In one
a solution of sulphate of iron is prepared either by
dissolving copperas in water, or by pouring sulphuric
acid on scrap iron in water. The solution thus pre-
pared is poured into the vat containing the gold solu-
tion. Any remaining red color of the permanganate
immediately disappears and a bluish-green color
takes its place. This color depends for its intensity
upon the quantity of gold held in solution, the pig-
ment being the gold itself — no longer in a state of so-
lution, but one of suspension in the liquid. The gold
is now in a state of molecular division — too finely di-
vided to be visible to the naked eye except by the hue
it gives to the liquid, but yet sufficiently palpable to
gradually sink to the bottom of the liquid if sufficient
time is given. In twenty-four hours the whole of the
gold will be deposited at the bottom of the vessel as
a black slime, and the liquid will be gold free. The
liquor is then run off or decanted and the slimes are
roasted in a porcelain dish to drive off the moisture,
then mixed with fluxes, placed in a crucible and
melted. The resulting ingot is fine gold.
A Coal Conveyor.
The handling of run of mine coal, without breakage,
at the rate of 150 tons per hour is a matter which
coal operators will be interested in, especially those
working veins on high levels.
The illustration herewith is a view of one of the
Jeffrey wire rope retarding conveyors now used by
the Dayton Coal & Iron Co. of Dayton, Tennessee. It
is practically 500 feet in length and carries run of
" Pure Water is a Poison.
mine coal from the upper level to the tipple and cars
located below. The carrying side of the conveyor is
lined with heavy sheet steel, in which the cable with
its special flights operates. The coal is fed into this
runway and is carried along on the horizontal plane
by the conveyor flights, while on the incline the same
flights simply act as a check to keep the coal from
running away.
A small engine is used to start the conveyor. This
system is inexpensive in its first cost, has large ca-
pacity and is continuous in its operations ; the cost of
maintenance is slight.
It is replacing the tram car system in some places,
which indicates its value where the merits of this
type of lowering coal are known. For catalogue ad-
dress the Jeffrey Manufacturing Co. , Columbus, Ohio.
The production of crude petroleum in California in
1899 was 2,642,095 barrels, valued at $2,508,751,
about 95 cents per barrel. As compared with 1898,
there was an increase of 384,888 barrels in production
and 10 cents in the average price per barrel. Los
Angeles county, which takes first rank in the amount
of production, produced 1,398,690 barrels, valued at
95.3 cents per barrel. Out of the total quantity pro-
duced in Los Angeles county, 1,022,966 barrels, val-
ued at $960,726, or 93 cents per barrel, were produced
in Los Angeles. The other counties of California
which produced petroleum, ranged according to their
output, were : Ventura, 496,200 barrels ; Fresno,
439,372 ; Santa Barbara, 208,370; Orange, 108,077 ;
Kern, 15,000.
Eastern reports agree that the American Tele-
phone & Telegraph Co. (which now .includes the
American Bell Telephone Co.), the Telephone,, Tele-
graph & Cable Co. of America, the Western Union
Telegraph Co. and the Postal Telegraph Cable Co.
will consolidate into one big company to be known as
the National Telephone & Telegraph Co.
This is the startling proposition put forward by
Dr. Koppe in an article in the Deutsche Medicinische
Wochenschrift. He says :
By "chemically pure water" we usually under-
stand perfectly fresh, distilled water, whose behavior
and properties are well understood. It withdraws
the salts from the animal tissues and causes the lat-
ter to swell or inflate. Isolated living organic ele-
ments, cells, and all unicellular organisms are de-
stroyed in distilled water — they die, since they
become engorged therein. They lose the faculty,
upon which life depends, of retaining their salts and
other soluble cell constituents, and consequently
these are allowed to diffuse throughout the water.
Distilled water is, therefore, a 'dangerous protoplas-
mic poison. The same poisonous effects must occur
whenever distilled water is drank. The sense of
taste is the first to protest against the use of this
substance. A mouthful of distilled water, taken by
inadvertence, will be spit out regularly. The water
once in the stomach, the superficial stratum of
epithelium experiences a powerful distension, the
cells are leached by their salts, die, and are cast off.
This local poisonous effect of distilled water makes
itself known by a sensation of uneasiness, belching,
etc., furnishing all the symptoms of a catarrh of the
stomach on a small scale.
The harmfulness of the process, so much resorted
to to-day, of washing out the stomach with distilled
water, is acknowledged, and we find the physicians
who formerly used that agent are now turning to the
"physiological solution of cooking salt," or " water
with a little salt," or the mineral waters recom-
mended for that purpose. The poisonous nature of
absolutely pure water would surely have been recog-
nized and felt long since, were it not that its effects,
I in their marked form, can seldom occur, for through
a train of circumstances, "absolutely
pure " water can rarely be found. The
ordinary distilled water, even when
freshly distilled, is not really absolutely
pure, while that used in the laboratories
and clinics is generally stale, has been
kept standing in open vessels, generally
in rooms where chemicals of every sort
abound and whose gases and effluvia are
taken up by the water.
The relative purity of samples of dis-
tilled water is best determined by the
electrical conducting power of each, since
the latter rises regularly and uniformly
with the increased impurity of the sample.
The purest water has but a small conduc-
tive power, since water is readily decom-
posed into hydrogen and hydroxyl (H and
OH). To illustrate this fact, let us ex-
amine some investigations of Oswald and
Koppe (the author), in which the numerals
represent ohms multiplied by 1010.
Oswald used in his physical work wa-
ter with the conductive index of 2.13. A
similar water was obtained by Kohlrausch
and Heidweiller by melting natural ice.
Koppe obtained, by melting natural ice,
a water with 8 as an index of conductivity.
Ordinary distilled water gave 49.2, and
ice prepared from distilled water which
had been boiled gave, on melting, 1 with the index
10. The following are the indices of certain German
waters :
Gasteiner Giftbrunnen ("poison
springs ") 31.9
Water from artificial ice 137
Vienna, public mains 220 to 239
Giessen, public mains 296
Selterswater, natural 5. 700
Salt, solution 0.73% 11.050
Salt, solution 1.46% 20.038
" Water melted from natural ice," proceeds Koppe,
" was purer than even boiled distilled water. Our
patients are delighted when we get for their use this
transparent and brilliant ice, and we (as physicians)
think that surely nothing can be safer than water
melted therefrom — but many a belch comes from the
stomach of the patient allowed to hold a bit of the
ice in his mouth and swallow the water. If this pro-
cess is permitted for any length of time we hear
complaints of 'weak stomach,' 'catarrh of the stom-
ach,' etc., which we must charge up — solely to the
purity of the water !
' ' And here it is all the worse. In the mouthful of
' pure water ' taken inadvertently in the laboratory,
as stated, the sense of taste comes to our rescue, and
we spit it out, but here the sense of taste is benumbed
by the cold."
This explanation seems to be all the more reason-
able when patients with hitherto healthy stomachs,
who, after operations, are for any reason allowed to
swallow "ice pills," begin to belch, and not infre-
quently contract catarrh of the stomach. There are
well known sequelae of the use of ice, but up to the
present no reasonable hypothesis has been offered as
to the etiology of the same. It has been charged, it
is true, to the "bacteriological contents" of the ice,
but examination of the latter has demonstrated it to
be almost free from bacteria such as would account
for the phenomena, though otherwise frequently con-
taining bacteria. As a remedy our clinicians say we
must use only artificial ice, made from distilled
water. Well, it is possible that artificial ice may be
better borne than the natural, but it is not because
it is purer than the latter, but exactly the contrary.
It is simply because the melted water thereof more
closely approaches our ordinary drinking water.
This point in the care of the sick, which is cer-
tainly worthy of investigation and explanation,
finds its analogy in the daily experiences of the
traveler in high mountainous regions. The guide
books warn him against quenching his thirst
with snow and glacier water, and the waters
of the mountain brooks as well, for, in Germany,
these not only do not quench thirst, but give rise to
much discomfort. With the greatest possibility of
being correct, we may assume that snow and glacier
water are of the highest degree of purity, approach-
ing distilled water very closely, or, indeed, excelling
it in purity (see the index of electrical conductivity
of the Gasteiner Asche above — only 31.8, even less
than the ordinary distilled water. The index of the
Housbrunnen in the Kurhaus at Provencheres, in
Gastein, is only 31.6).
The harmfulness of glacier water, like that of the
pure, cold mountain brooks, most of which, indeed,
spring from glaciers, arises from the fact that they
are exceedingly pure waters and produce identically
the effect of the use of distilled water — they are poi-
sonous. The supposition that the coldness of the
water causes the sick, uneasy feelings cannot stand
for a moment, though this coldness is very probably
the reason that its unfitness for use is not at once
recognized and the liquid rejected.
The last link in our chain of prolegomena is found
in the case of another of the Gastein springs. The
water of this spring has an electrical conductivity of
31.9, therefore far excelling ordinary distilled water
in this respect, and hence, according to our proposi-
tion, its use should demonstrate the poisonous nature
of pure water. By a most strange coincidence, from
the oldest times, for hundreds and hundreds of years,
this spring has been known as the gift-brunnen — the
"poison spring." Its water is never drank; it is
commonly regarded as poisonous, although no chemi-
cal examination of it — and they are almost innumer-
able— has yet been able to detect the slightest trace
of any poisonous substance. Its poison lies in the fact
of its extreme purity ! This, we know, is a proposi-
tion that nobody will take in earnest — still, it is devoid
of anything wonderful in a physiological point of view,
and, furthermore, it is borne out by fact.
American Miners in Korea.
Thos. Woon of Nevada county, Cal., has returned
from Korea and tells the Union that developments
are under headway and show Korea to be rich in
mineral wealth. The operations at present are con-
fined chiefly to gold mining. The gold is found in
quartz ledges from 1 to 17 feet in thickness, gener-
ally rich from the outcroppings down. The mines are
old ones, partially developed, and appear to have
been worked for centuries past. The natives never
worked them below the water level, having no pump-
ing machinery or other appliances for removing the
water. The advent of American machinery and mod-
ern methods have changed affairs and the richer
deposits are now being worked successfully. No
prospecting for locations is necessary, as the old
shafts made by the natives are taken as indications
of paying ledges. The land is owned by the Govern-
ment, and an American who wishes to engage in min-
ing secures a concession through the resident consul,
something which is easily accomplished with proper
representations and the payment of certain sums for
the privilege of mining.
The Oriental Con. M. Co. of New York is mining on
a large scale at a point about 300 miles in the inte-
rior, with good results. This company employs 1500
Koreans and a few Chinese in the mines, also about
forty Americans or Europeans, who act as foremen or
bosses. The white men employed are usually miners
who have had experience in mining elsewhere. The
milling is done on the ground, excepting a small
quantity of sulphurets, which is shipped to the smelt-
ing works in San Francisco. The machinery and
large quantities of mining supplies are shipped from
San Francisco to Nagasaki, Japan, and are then
transferred to a small steamer, which carries them
to the Korean coast. They are taken up an inlet
and a river far into the interior and landed a few
miles from the mines. Bull carts and ponies are then
used for freighting from the landing to mining head-
quarters. A considerable quantity of canned goods
and provisions come from London to supply the wants
of the white men engaged in the mines.
The New York company, of which J. Sloat Fassett
is a large stockholder, is managed by Leigh Hunt,
who gained a concession and interested capitalists
in the proposition. Now the property of the com-
pany is valued at high figures. The Chittibalbi mine
is one of the best of the group.
The climate of Korea is dry, the heavy rains fall-
ing in July and August. The winters are cold and
the mercury often registers 25° below zero. The in-
habitants are mild-mannered, peaceable people, and
it is safe to travel anywhere. The foreigners carry

firearms and the Koreans are afraid of them, know-
ing that they have the protection of the Korean
Government at present. However, there is a hatred
of the foreigners, and if the natives were encouraged
they would attempt to drive them out of the country.
In case the Chinese trouble should spread, or Japan
and Russia engage in a general war over Korea, the
ports would be blockaded and the safety of Ameri-
cans and Europeans might be endangered.
There are no railroads in the vicinity of the mines,
and no newspapers are published. Bulletins are
posted occasionally at headquarters, however, giving
news from the war. It is a cheerless country in
which to live, though thickly settled by natives.

About $100,000,000 worth of india rubber has been
imported into the United States during the past four
years, and about $60,000,000 worth in the last two
years. Ten years ago the annual importations of
india rubber amounted to about $15,000,000; now they
exceed $30,000,000, and are steadily increasing.
Practically all of the importations of rubber come in
crude form for use of manufacturers. Northern
Brazil, southern Mexico, the West Indies, Central
Africa, India, the Straits Settlements and the Dutch
East Indies supply this increasingly important feat-
ure of our importations.

To Splice a Wire Rope.*
The only tools needed are a cold cutter and ham-
mer for cutting and trimming the strands, and two
"needles " 12 inches long. These latter are made of
good steel, i inch thick at one end, tapered ovally to
a point, and having a handle riveted on, as shown in
Fig. 3.
When the rope is cut and ready for splicing, un-
wind three strands of each part 15 feet, keeping
them together and not separating them. Now cut
out the hemp center to the point x, as shown in Figs.
1, 2 and 3 ; rewind the strands for 7 feet to A, and
cut off three of them from each end of the rope at
A, A, Fig. 1. Then, as shown in Fig. 1, from x to A
the rope is without a hemp center. Draw the two
ends A together, letting B, B pass, as shown in
Fig. 1 ; uncoil the strands e, d, c, Fig. 2, keeping
them together, and follow immediately with the long
strands e' d' c', holding all the strands firmly and
keeping them together so that the three long strands
e', d', c' will take the place of the short strands
e, d, c ; next, do the same with the strands f, a, b,
keeping them together as before, and laying them in
the places from which f, a', b' have been uncoiled.
Take about two turns around the rope with these ;
the operator will then find that the rope is united and
round, as shown at Y, Fig. 3. Now take the short
strand a', Fig. 2 ; unwind it, and follow with the long
strand a, making two wraps or turns around the
rope ; then unwrap the short strand b', and follow it
with the long strand b, making the long end fit in the
place previously occupied by the short strand of the
same letter ; do the same with f, e, d and c, until the
last strand reaches x, Figs. 1 and 3, at the two ends
of the splice. By following these directions closely it
will be unnecessary to tie the strands, as each strand
locks the other, and there is no danger of entangle-
ment if care be taken that the strands follow one an-
other in their natural order.
After cutting off the ends of each strand the rope
will have the appearance shown in Fig. 3, where, if
the ends were tucked in, e' would butt against x, e
♦ From the Mechanio Arts Magazine.
against c', c against d', d against a', etc. The next
operation is to run the strands into the middle of the
rope. To do this push the needle A, Fig. 3, through
the rope from the under side, having three strands
in front of the needle and two at the back, the strand
e being back of the needle. Push the needle B
through from the upper side, having the strand e in
front of the needle ; push the needles as close together
as possible with the strand e between them ; place
the needle A on the knee and hold it there firmly,
then turn the needle B around the coil of the rope,
forcing the strand e' into the center of the rope.
Continue similarly with all of the strands, and should
any of them seem too full tap them lightly with the
butt end of the needle, which will round them off and
fix them into place. All of the strands should meet
as nearly as possible in the center, as they take the
place of the hemp center, and this will keep the rope
round and prevent the slipping of the strands.
The splice as thus made may seem at first some-
what rough, but a little use of the rope will overcome
all irregularities. A beginner should make several
splices on a rope that is not in use. If the above
directions are followed, after a little practice any
man can make such a splice in thirty minutes, and if
pushed it can be done in twenty minutes ; but this re-
quires two men, one coiling and uncoiling, while the
other follows up with needles and cold cutter. To do
this the hemp center must be left out, as shown in
Fig. 1.
A new rope, owing to the wild character of the
strands, must have the hemp center left in ; other-
wise the operation is the same, excepting that, when
ready to run in the strands, the needle is pushed
through at x, Fig. 3, and turned so that its broad
side will be at right angles to the rope ; cut the hemp
center and pick out enough of the center by turning
the needle around the coil of the rope to let in the
strands e' and e ; put in e' and e, and then push the
needle through at the end of the strand e, taking out
enough of the hemp center to put in the strands
c' and c ; continue this until all the strands have been
entered. With a new rope it will take one hour to
make the splice.

Mixing of Concrete.
The following account of the mixing of the con-
crete for the piers of the new ship canal at the en-
trance of Duluth Harbor, Minn., is of interest,
showing the careful way in which the work was done,
and is from a report of Major Sears, W. S. of the
Engineer Corps.
"The mixing was done on movable platforms,
which were always placed alongside the molds to be
filled. Mixing on the molding platform was prohib-
ited, to insure the preservation of a smooth molding
surface for the base of the blocks. The pebbles were
always thoroughly washed, and while moist from the
washing were transported in measuring carts of one-
half cubic yard capacity each to the mixing platform,
dumped and spread to an even thickness of 6 inches.
The sand was spread on the pebbles in a like manner,
and the cement, after being weighed, was spread on
top of the sand and pebbles. After a thorough mix-
ing dry, the mixture was again spread out on the
platform to an even thickness of 6 inches, and water
was added carefully, the mixing proceeding as the
water was being applied, and continuing until the
mass was in such a condition of plasticity that five
or six sharp blows from the back of a shovel would
produce a glistening appearance upon the surface of
the concrete so treated. The concrete was then
immediately shoveled into the molds, and, after being
spread in layers not more than 5 inches deep, was
thoroughly rammed with iron rammers having a face
area of 25 square inches and weighing forty pounds
each. Special flat rammers of oak shod with J-inch
steel were used for compacting around the sides of
the mold. No attempt was made to provide special
material for the surface of the block, a smooth and
handsome appearance being accomplished by thor-
ough ramming of the concrete. The batches as
mixed contained each one cubic yard of pebbles, one-
half cubic yard of sand and 432 pounds of cement.
As indicated above, the pebbles and sand were ac-
curately measured and the cement was always
weighed."
Some Facts About Steel.
The term steel signifies iron containing a small per-
centage of carbon, which may vary from less than 1%
to 15%. In modern times steel signifies iron that
has an infinitesimal amount of carbon in it, provided it
is produced by the open hearth or Bessemer process.
Meteoric iron is a close representative of nickel
steel, and was used by the ancients. The majority
of steel in the early times was obtained from wrought
iron. Wrought iron is produced from cast iron
melted in contact with iron cinder and iron ore, and,
when cooled and worked, again heated in closed ves-
sels with shavings of horn and similar material.
The most important invention in connection with
the production of steel was that of Sir Henry Besse-
mer and termed the Bessemer process. The Besse-
mer process dates back to the fifties. The essence
of this invention was the production of steel from
pig iron by the use of an air blast. A blast of air is
forced through the molten cast iron so that the car-
bon and silicon contained in it are burned out, they
forming the fuel. The converter in which the metal
is treated by the Bessemer process is an egg-shaped
vessel having a capacity of several tons, which is
turned on its side to receive the charge, and after-
ward brought into an upright position. Its bottom
is full of holes, through which the hot air blast is
forced.
Steel under the intense heat of a converter is as
liquid as water. In 1878 a great advance was made
in the art by Sidney G. Thomas, by which ordinary
grades of iron ore were rendered available for steel
making. The Thomas invention related to the addi-
tion of a quantity of lime to the charge, and the lin-
ing of the converter with special bricks formed of
lime, which absorbed the phosphorus in the cast iron.
The slag obtained by the Thomas process is found to
be rich in phosphorus, and is used largely as a fertil-
izer. The Thomas improvement is considered the
greatest yet made on the Bessemer process.
Following the Thomas discovery, the next import-
ant improvement in the process was that made by
William Siemens in 1882, which consisted in burning
the fuel so as to produce a gas which was burned in a
peculiar furnace, obtaining thereby high tempera-
ture and great economy of heat.
The tenacity of good steel is very high, exceeding
that of any other metal. The fractured surface of
steel generally presents a crystalline appearance,
uniform in strength. Much carbon makes steel close-
grained and lustrous. Natural steel is obtained by
refining cast iron so as to deprive it of a sufficient
portion of carbon to bring it to a malleable state.
Indian or Wootz steel is made by melting one pound
of malleable iron in a crucible with 10% by weight of
the wood and leaves of the plant Cassia ariculata.
Mild steel contains from -£$% to ^5% carbon. When
more is present it is termed hard steel.
Steel in its hardest state is too brittle for most
purposes, and the requisite strength and elasticity
are obtained by tempering, which is performed by
heating it to a certain color, dependent on the use to
which it is to be put, and cooling quickly. The ten-
sile strength of steel ranges from 75,000 to 96,000
pounds. The average is about 86,000 pounds. A
hemp rope 16.5 inches in circumference would be the
equivalent to a steel rope 5 inches in circumfer-
ence.

CALIFORNIA.
AMADOR COUNTY.
(Special Correspondence). — Mr. Joyce,
one of the owners of the Defender mine at
Camp Contreras, desired to sell the mine
and had a flattering offer for it. But his
partner did not wish to sell. The mine
has been bonded at good figures; the
bonders are to sink a shaft 300 feet deep,
to put up a new mill and hoist, and make
other extensive improvements. They will
not be allowed to take any ore from the
upper or present workings, but must get
all they take out from the shaft as they
go down. The Defender has been a pay-
ing mine for the past two years, and the
money that has been paid for the present
mill, hoist, etc., has been taken out of the
shaft, no drifting having been done. It is
a good property,
lone, Sept. 22.
(Special Correspondence). — The Lincoln
mine, under the management of E. C.
Voorhies, is going ahead with good
prospects. The Mutual mine, a location
north and east of the Lincoln, has a ver-
tical shaft down 300 feet, drifting south
and crosscuttingwest.
The Central Eureka has just completed
one of the best 10-stamp mills in the
county, with electric power and all else
which makes a complete saverof the gold,
of which there is a liberal amount in the
ore. This mine has developed into a good
property, and its future at the present
depth of 1800 feet is promising. The South
Eureka, south of the Central Eureka, has
improved in valuo of late; credit is due
the stockholders who have been digging
up assessments. It is believed that Supt.
Parks' skill will bring them out all right.
The Oneida mine has a finely equipped
steam hoisting works and mill; location
most favorably situated for cheap work.
In the Kennedy mine, whose reputation
as a dividend-payor is well known, the
new vortical shaft is making good prog-
ress, preparing for permanent steam hoist,
which will bo equipped with all modern
improvements; forty stamps are running
as usual; chlorination works always pro-
ducing.
Sutter Creek, Sept. 25.
Tho Shenandoah M. & M. Co., through
S. K. Thornton, has made final payment
on tho Shenandoah mine, near Plymouth.
The shaft has been sunk 500 foot, stations
cut and drifts run on the 200, 350 and 500
foot levels, north and south. Milling tests
havo proved satisfactory, running from
$5 to $13 a ton.
Record : The Peerless mino has a depth
of over 400 feet, sinking being pushed.
Water power is being used at the Oneida
mill for the present, the Electric Co. not
having sufficient power to run the mill at
the time of its completion. Only twenty
of the sixty stamps are in operation.
Dispatch: The east shaft at the Ken-
nedy mine is down about 1630 feet. The
first ground for this shaft was broken in
November, 1898, and, at the present rate
of sinking, the 3100 feet which it was in-
tended to sink at the outset will be at-
tained by the end of three years from the
start. Good work has been done.

(Special Correspondence). — The Black
Bear mill is running sixteen stamps on
good ore. They have a 32-stamp mill on
the property, arranged in 4-stamp bat-
teries, but lack of water compels them to
hang up sixteen stamps. Development
work is being carried on. At the White
Bear men are prospecting for the old ore
body that paid $14,000 and then pinched
out. At the Black Bear the main tunnel
is in 950 feet. The vein is being followed
down from near the end of the tunnel. If
the ore holds out Supt. Dagget is going
to sink a vertical shaft from the surface
and crosscut to the vein. The Black
Bear has paid $3,000,000 since it was
opened up, and is good for years to come.
Twenty men are employed.
At the Ball mine, near Rollin, on the
1st. Supt. L. D. Ball doubled his force ;

will be taken out. New ore bodies will be
opened up there this winter. At the M. I.,
another of the Ball group, development
work is being carried on and good ore is
taken out. Some of the ore shows free
gold. Ore is being taken out of the
Mountain Laurel, adjoining the M. I.

TELLER COUNTY.
There was a sensation at the Elk ton
mine last week. For some time it had
been suspected that some of the miners
had been guilty of stealing high-grade ore
and detectives were put to work in the
mine with the suspects. When the shift
came off on the 19th inst. each man was
searched, and seven were found to have
ore of very high grade hidden in their
pockets. All were arrested by a posse of
officers. Supt. Camp estimates that fully
$10,000 worth of ore was stolen last month
from the mine. The ore taken from those
searched is estimated to be worth at least
$500.

four-horse team loaded with butter and
eggs, and was hauling near Warren and
drove into a wet sag and got stuck. He
began digging around one of the wheels
and his shovel struck a quartz ledge which
proved to be 10 feet wide. He had some
of the rock assayed in Warren and it went
$10,000 a ton. Miller was offered $60,000
for his claim, but refuses to sell." It is a

MADISON COUNTY.
The deal for the purchase of the Boss
Tweed and Clipper groups of mines at
Pony is reported off. The intending pur-
chasers were to make the first payment
last week, but failed to do so. The option
lapsed and the properties revert to the
former owners. It is understood that the
hitch in the negotiations was not due to
any lack of faith in the richness of the
mines, but to the fact that a big payment
in advance was demanded, and that the
owners of the Boss Tweed and Clipper re-
served for themselves eight of the best
properties of the group, all of which sur-
rounded the two developed mines.
Two corporations have bought the

The Dragoon mines are owned by the
Federal Copper Co., composed of G. W.
Jacobs and others in New York City. The
company bought a site for the plant and
tracks at El Paso last winter. Mr. Clif-
ford says that the company has practi-

trust which he says was formed two
months ago when the Guggenheim smelt-
ers raised $2 per ton on treating ore. The
Dragoon or Federal Co. has been one of
the largest patrons of the El Paso smelter

end is attached. A sprocket wheel is
turnable journaled upon said lever in line
with the lower part of the driving chain,
where it passes between the pedal shaft
and rear axle sprockets so that when the
pedals are pressed backwardly or against
the forward movement of the machine,
the tension of the chain will press upon
the sprocket, and act through it and the
lever to pull the band into frictional con-
tact with the rim, sufficiently to retard or
stop the progress of the machine
Car.— No. 658,142. Sept. 18, 1900. G.
A. & R. F. Dunn, Dinuba, Cal. This in-
vention is designed to provide a car hav-
ing a self-contained mechanism by which
its direction of travel may be changed
without independent or exterior appli-
ances. It consists of superposed frames
having wheels journaled at right angles to
each other, and side links pivotally con-
nected at opposite ends to the frames so
that one frame may be raised above or
lowered upon the other. There are
means for connecting the frames to hold
them together when the lower one has
been raised into contact with the upper
one, and this allows the wheels of the
upper frame to rest upon the track or
surface while those of the lower frame are
lifted independent of the surface. When
the lower frame is depressed and the upper
one raised the reverse operation takes
place and the other set of wheels are then
In position to support the weight of the
car and to carry it in a direction at right
anglos with the first set.
Concentrator.— No. 658,120. Sept.
18, 1900. J. W. Pindor, Groveland, Cal.
This invention relates to a device for con-
centrating hoavy materials and after-
wards separating the lighter and worth-
less material therefrom. It consists of a
table, the head of which is made concave,
and the lower end connecting the said
head portion is inclined both lengthwise
and sidewise. In conjunction with this
table are a serios of diagonally disposed
tapering ritties parallel with the side of the
table, and separated from the first named
series. The discharge from each series is
received upon the next, and the upper end
of the table is supported on vertical stand-
ards upon each side so disposed as to al-
low a perfect freedom of movement which
is produced by the operation of a hori-
zontal crank wheel centrally connected
with the head so that a revolving motion
is given to tho head of the table, while
the lower end reciprocates with a longi-
tudinal movement upon supporting wheels
or rollers. The compound movement
thus produced acts as previously stated.

The Chinese imbroglio has greatly af-
fected Mexican currency. The drain upon
Mexican silver dollars for export to the
Orient has caused a scarcity in the circu-
lating medium at the City of Mexico, and
exchange has dropped from 2.10 to 2. In-
terest rates have risen from 6% to 12%,
and premiums of 8% are offered on the
intrinsic value of the Mexican dollar by
exporters.

CROWN GOLD MILLING CO.
Manufacturers of the "CROWN" CONCENTRATOR and CROWN
ORB SIZER. A dry process of sizing and concentrating ore, sand or
gravel. Designed to accord fully with the laws of specific gravity,
and especially adapted to refractory ore or localities where there is
no water.
The chief claims for the Crown Concentrator are that it occupies
less floor space and has nearly four times the capacity of any wet
concentrator; that it will concentrate ores containing base and refrac-
tory metals that ordinarily slime and carry off values; that it effects
a saving of values far above the ordinary methods of concentration -
Wc have, now in operation, a complete plant
for crushing, sizing and concentrating ores by the
Crown Dry Milling Process.
Mine owners desiring tests made can forward
us, freight prepaid, not less than 1000 lbs. nor
more than 4000 lbs. of sample, for which a
charge of $20 will be made. (This amount in-
cludes assaying, etc.)
Ores for which this process is adapted and of
which consignments are solicited are any con-
centratable ores, pulps, tailings, or sands, carry-
ing sufficient values, whether they have hereto-
fore been profitably concentrated or not.

THE GRIFFIN
THREE ROLLER
ORE MILL.
The Griffin Three Roller Ore Mill is a simp.y constructed Mill, suitable for working all kinds of ores that
require uniformly fine crushing by the wet process. This Mill is a modification of the well-known Chilian
Mill, but the rollers run upon a crushing ring or die, which is inclined inwardly at an angle of about 30 degrees,
the rollers themselves also being inclined to the central shaft of the Mill, thus utilizing the centrifugal force,
as well as the wolght of the rollers themselves as a crushing agent. The Griffin Three Roller Ore Mill is there-
fore a Mill of great strength, and has few wearing parts. We construct these Mills with extreme care, using
only the best of raw materials, which are most carefully worked by men who are specialists as mill builders.
We sell the Griffin Ore Mill on its determined merits, and will gladly supply full Information regarding it to
any one.

who says there's nothing equal to the Wilfley, and I am trying to

there's anything made to equal it."

The Ideal Conveyor Belt
Is the one that will carry stone, ore, coal, wet or dry
material, holding buckets firmly and securely; will
stand all kinds of exposure, and resist the heaviest
strains during a long period of service. This Is what
the LEVIATHAN BELT has done, and we quote the
following from a letter from the New York Steam Co. :
"We have used Leviathan Belting for four years, up
to 24-inch by 8-ply, elevating and conveying coal. Some
of the Belting is outside, exposed to freezing weather;
some in a steam bath. In both conditions the results
have been very gratifying, over 500 tons having been
handled in ten hours time."

Mining Frozen Ground in Siberia.
In the basin of the Amur, methods of mining the frozen soil of Siberia are interesting.
The number of days in the year in which the temperature of that part of Siberia is below
freezing point is about 200 ; the mean temperature for the whole year is below freez-
ing point ; the lowest temperature reached is — 37° O, the highest +27° C. The tem-
perature conditions of the whole year tend to form ice rather than to melt it, and the
whole of the superficial layers of the earth's crust are thus completely frozen. The miner
has accordingly to deal with gravels frozen hard, though in places certain local actions
may k'.ep patches of ground from freezing, especially in swampy districts, so that the
possibility of the workings being suddenly flooded is always present, in spite of the frozen
condition of the ground. Frozen alluvium contains from 1% to 12% of ice ; in this condi-
tion it is hard and tenacious, does not break under the pick, and dynamite and powder
have little effect upon it. Hence these frozen gravels can only be worked by thawing, as
in the Klondike, either naturally by the action of the sun's rays in the short summer sea-
son of about five months, or artificially. Direct flames, heated metal and steam have been
tried, but only the first-named method is of any use. Practice has shown that a layer of
burning wood properly applied will only thaw out its own thickness of frozen gravel, while
it is impossible to thaw out a greater depth than'one foot at each operation. When thus
thawed, the gravel can readily be got out by means of the pick. At the placers of the
Daourskaia Company, near Nertchinsk, three methods of mining the auriferous deposits
are in use — open-cast working by hand, machine excavation and underground work. The
first two methods are only applicable in the summer season ; the last named can be
worked all the year round, but is confined to
the winter time, as it is preferred to employ
all available hands at the surface as long as
possible. The open working presents no
peculiarities except that the depth of each
face is very small, about one foot, to enable it
to be thawed by the heat of the sun ; strip-
ping the barren surface earth is commenced
as early in the year as possible, to expose
the greatest possible surface of auriferous
gravel to the influence of the sun: an average
day's work amounts to three cubic yards
of excavation per head. The machine exca-
vator is only used for raising old tailings that
have been worked, but which contain suffi-
cient gold to be worth working over again.
An interesting method of working is under-
ground ; shafts are sunk along the axis of
the placer down to the bedrock, about 55
yards apart, and connected by a drift run-
ning on the bedrock and about 14 feet wide.
From this drift crossdrifts are driven 14 feet
wide and 14 feet apart to the rim rock of the
placer ; these crossdrifts are then connected
In Ore— Main Drift, 100-Foot Level.
by short cuts 14 feet wide, leaving the whole
deposit thus cut into pillars 14 feet square,
one-fourth of the whole area being left stand-
ing in the form of these pillars. After a dis-
trict has thus been laid out the pillars are
systematically robbed, working from the
limits of the placer backwards and allowing
the roof to come down. The complete work-
ing out of a district takes about three years.
During the course of this operation a system
of timbering is employed, consisting of close-
fitting sets of timber framed of round wood
six inches in diameter; in the main and cross-
drifts these sets are kept in place by longi-
tudinal timbers along the workings ; all work-
ing faces are also kept close timbered.
The timber protecting the face to be
worked is removed, firewood is piled against
it, covered with a layer of charcoal to keep
the heat down as far as possible, and set fire
to ; when the face is sufficiently thawed the
fire is extinguished and the thawed ground
cut down by the pick, fresh timber put in,
and the work proceeds. One difficulty is
that the heat required to thaw the face naturally rises in spite of all precautions and
produces dangerous hollows above the roof timbers, together with falls of ground that are
a source of accidents. The consumption of wood for mine timbering and firewood is great.

A Large Pump.
The work of dismantling a huge Corliss pumping engine is going on at Allentown, Pa.
The pump was constructed in 1868 for the Lehigh Zinc Co., for obtaining water from a
mine. The cost of building and installing the engine was almost a million dollars. The
difficulties of erection were rendered greater by the engine being placed near the mine
shaft. The engine frame and bearings are bolted to solid cut-stone masonry, 80 feet deep.
Owing to the fact that the mining interests waned, it was decided to abandon the engine.
It has not been operated for three years. At the time its destruction was begun it was
in excellent condition. Dynamite is being used to throw down the heavy walking beams
from their bearings, while block and tackle will prevent them from falliDg after the ex-
plosion. After that each one will be broken into suitable sizes for shipment. It is esti-
mated that there are sixty tons of brass in the bearings and fittings. The height of the
engine from the surface of the foundation to the top of the walking beam is 50 feet. The
weight of the entire engine is 1500 tons. The diameter of the steam cylinder was 110 feet,
the stroke 10 feet. The pump was intended to deliver 14,600 gallons of water per minute.
There were two walking beams mounted on the same shaft 10 feet apart. They were
jointed at their heads by many rods two feet in diameter, to which the connecting rods
were fastened. Each beam weighed forty-four tons. The flywheels were two in number,
one situated on each side of the steam cylinder, weighing ninety-eight tons. The fly-
wheels were 30 feet in diameter. The material goes to the junk pile.

One can now talk by telephone from San Diego,
Los Angeles, San Francisco, Cal., Portland, Or.,
Butte, Mont., Denver, Colo., and Salt Lake City,
Utah.
There is now a class of the miners employed at the
Comstock, Nevada, that regularly meets for study,
to qualify the members for the degree of mining en-
gineer to be conferred by the University of Nevada.
The idea is in every way commendable and worthy of
practical observance.
Municipal ownership of any great public utility
can not be as much of a commercial success as pri-
vate ownership. No one working for a city will put
in daily use the brains, the energy, the watchfulness
and the economy of operation required in private
ownership and business competition. This is not be-
cause of lack of honesty or public spirit or good in-
tent. It is so because of the very nature of things,
and is not nearly so much a surprise that it is so as
would be a solitary instance where the opposite re-
sult were observable.
Last Monday the director of the U. S. Mint in-
creased the price to be paid by the Government for
silver from 55 to 57 cents per standard ounce. The
price has advanced unsteadily since 1896, when the
Government price was 47 cents. The present price
quoted commercially — 63J — is the highest for some
years, and is chiefly caused by large Asiatic and
European coinage orders. India has been buying all
summer, China began buying in August, and in Sep-
tember the British mint made considerable purchase.
Nearly all those orders were for October delivery.
During last month the U. S. Mints coined in silver

An old idea in a new garb is presented in a com-
munication from Sumpter, Or., which, boiled down,
alleges that the Standard Oil Co. is acquiring min-
ing property in that district ; that its tactics are to
do sufficient work on a prospect to develop its value,
and then cover it up, on the principle that it is safer
there than in any bank, can be produced at will, and
is not subject to taxes. Sumpter understands the
art of advertising, and the statement is a good bid
for prominence, which is here given it. The idea
attributed to the Standard Oil Co. was an old one in
the days of the Phoenician tin miners, but has not
been overworked lately.
Of Valued Service.
The receipt of the twentieth annual report of the
U. S. Geological Survey and a cursory examination
of its fine volumes shows how well that important
branch of the public service is filling its mission in
aiding the development of the nation's mineral wealth.
It is one federal work in connection with mining
that deserves just commendation, and it is only jus-
tice to say that with the limited means at their dis-
posal Director Walcott and his skilled assistants are
doing valuable work ; valuable to the prospector, the
miner, and the mine investor.
It is within the memory of men not yet old, as years
go, when metal ore deposits were considered as
' ' freaks of nature ; " when everything in connection
with mining was looked upon even by educated men
as a matter of chance or luck. But from chaos comes
cosmos, and out of the welter of shapeless beliefs come
laws as certain as those that regulate the passage of
the hours. The formulation of those laws is primarily
due to the miners themselves ; in almost as great a
degree to the mining engineers, metallurgists and
chemists, who have advanced mining and scientific
knowledge in theory and practice, and in these later
years the U. S. Geological Survey has done much to
determine data that are to the miner as well-made
maps to the traveler or soldier. The rule of three
slowly supplants the rule of thumb ; the old " where
it is, there it is" theory of gold formation and ex-
istence still has its devotees, but there is yearly a
clearer popular perception of the basic laws that
govern the basic industry of the nation, and for an
understanding of these primal laws we owe much to
the work of the U. S. Geological Survey.
The great work of creating a geologic atlas of the
United States goes on, and prominent mining dis-
tricts are successively given detailed attention. This
branch of the work has been already discussed at
considerable length. It forms but a part of the re-
search and publication constantly carried on. Gen-
eral geology, paelontology, hydrography or stream
measurement, forest reserves, description of promi-
nent mining districts, Alaskan explorations, are
among the subjects on which work continues. The
timeliness of this work is an added element of value.
For instance, on the last mentioned subject there is
a volume of over 500 pages — an up-to-date encyclo-
pedia on Cape Nome, Tanana and White River ba-
sins, the latest and newest, American gold districts.
Doubtless were there a great metal discovery of any
kind reported from Cape Barrow the U. S. Geologi-
cal Survey would have a bulletin out inside of a month
with the latest procurable facts and an elaborate
monograph thereon before the close of the year.
This prompt recognition of the immediate demands of
the prospector and miner characterizes the. policy of
the Survey, and while not neglecting the require-
ments of general scientific research, the more homely
needs of the day and hour are supplied.
The simplicity of truthfulness, the absence of favor-
itism, the regard for accurate determination of exist-
ing fact, the unbiased independence of statement and
the sterling character of the prompt information fur-
nished are among the attributes that give value to
the work of the Survey.
There is some present discussion as to the differ-
ence between American miners and those not Ameri-
can. One apparent difference does not seem to have
been touched upon as yet in the discussion, viz. , the
fact that miners working in American mines in any
capacity are not usually content to be told that a
thing is so without knowing why it is so, what made
it so. They do not care to have any one do their
thinking for them, preferring to do their own think-
ing, and are not looking for opinions or information
second hand. An instance of how this fact is not
generally understood elsewhere was recently af-
forded in the case of a man who visited this office
with a newly devised mining appliance of improved
merit that he wanted to have brought to the notice
of the mine superintendents of the United States.
He had two flattering testimonials, one from an Aus-
tralian mine manager, the other from a British min-
ing engineer, and asked that they be published,
saying " that will be all required." He was told that
a great deal more would be required, if he wanted to
enlist the notice of any mining men in America whose
attention was worth having ; that the best way to do
would be to furnish a sectional drawing of his device
and a brief technical statement of what it was in-
tended for and what could be truthfully claimed for
it, that American miners might read and decide for
themselves as to the merit or lack of merit of the
apparatus. To this the gentleman from England
demurred, claiming that all the miners need be
vouchsafed was to be told just what Messrs. So and
So of Australia and London thought of the machine.
This might do elsewhere, but would not win in the
United States, where there is no glamour of names,
and where miners pay little attention to anything
that does not appeal to their intelligence. With sur-
prise the representative learned that while the gen-
tlemen whose testimonials he held were doubtless
very worthy people, what they thought or did not
think about mining devices was of no material im-
portance to American miners, and that three lines of
description outweighed three columns of testimonials.
The instance illustrates one element in the mental
make-up of men working in American mines that has
not been touched upon in the discussion referred to.
The official call for the ninth annual convention of
the California State Miners' Association names Nov.
19th as the date and San Francisco as the place. It
is none too soon for the several county mining associ-
ations to begin the work of selecting delegates and
determining what shall be brought before the con-
vention. There are several matters of importance
to all sections of the State, and, also, questions
affecting different parts of its area that need atten-
tion. To give due heed to such requirements is a
part of what the annual convention is for. The con-
vention is the place to bring matters of general
value to the mining interests of the State that may
be aided. The convention is made up of the several
county organizations; they give it life, and constitute
its existence. The work of the association goes right
on through the year; it is continuous through its
committees; part of the business of the annual con-
vention is to hear the reports of those committees,
and instruct them as to future action. But of equal
importance is that the several county organizations
formulate their needs and ideas, and present them in
convention. The meeting of 1900 should be as large
in numbers and profitable in results as any of its pre-
decessors. '
Rhodesia, South Africa, understands the art of
advertising, and is up-to-date in claiming attention
to its gold mines. Assertion is made that as soon as
the Boer war is over a railroad will afford all modern
advantages. Figures are furnished regarding one
mine — the Globe & Phoenix — that sound as familiar
as similar calculations nearer, home. The figures,
which of themselves do not lie, say that 5907 tons ore
were crushed in twenty-four days, yielding, on the
plates, 4742 crude ounces, and a profit of $62,831.38.
The expenses are stated to be $29,486.12; so that
the 4742 ounces must have produced $92,317.50, or
$19.46 per ounce, which for crude gold is extraor-
dinarily good. It is very seldom in South Africa that
gold .942 fine is produced. Of course, that affords
fine base for the prospectus : " Take an average of
£13,000 profit a month," says the Review; "then
we get £156,000 a year net!" Of course we do!
The London Rhodesians have nothing to learn of the
boomer's art, and do not bother about little things
like facts.
' ' Is the Paris Exposition profitable to the exhibit-
ors ?" is a question now being discussed toward the
close of the latest international .exhibition which
rounds out fifty years of such display. The general
expression of opinion seems to be that the exhibition
did not pay those who exhibited. This paper thinks
differently. It thinks that such exhibition was op-
portunity for good advertising ; and a good adver-
tisement of a good article always pays. Those who
are adverse in their comment on the conduct of the
big Paris show are, however, undoubtedly right in
saying that the wholesale giving of medals and hon-
ors brings the whole thing into contempt. In a
manifest desire to please every one the French fair
directors have cheapened their awards and have per-
manently hurt whatever prestige attaches to their
receipt. The fact that the fair itself is not a finan-
cial success will go far toward deferring any future
effort of the kind in any European capital.

SOME millmen claim that the formation'of " verdigris "

One of the reasons for the cost of zinc reduction is due

Sludge in final precipitation vats in gold ehlorlnation
plants has value dependent upon the care and skill exer-
erclsed In chlorinating, and, in a degree, upon the quality
of the ore. The gold obtained by final treatment from
the sludges will not ordinarily exceed 2% of the total
gold obtained in the chlorination works.
The only new thing sought by the majority of devisers
or designers of new steam engine forms is to utilize more
of the heat generated by the fuel consumed. As only
about 50% of the units of heat in the fuel is utilized, there
is still room for manifest advance. The form or ar-
rangement is of little consequence ; the commercial point
is economy of operation.
There are no mechanical difficulties in the way of
using crude alcohol as the working agent in oil or gas

one-fourth times as much as if petroleum spirit were
the combustible employed.
That quartz veins may be of comparatively recent
origin is exemplified by such occurrences as that near
Volcano, Amador county, Cal., where a distinctly
marked quartz vein is observed to cut through beds of
sand and gravel, presenting unmistakable evidence of
having been formed subsequently to their deposition by
the action of siliceous waters.
In a laboratory method of making sodium amalgam a
flask of mercury Is heated to about 300° F., and then
small pieces of sodium, about the size of a pea, are gently
dropped in, one at a time, until 3% is added. As each
little pellet Is dropped into the hot mercury a little ex-
plosion occurs, and the operation is necessarily slow.
When the requisite percentage of sodium has been added
the merourj is poured Into a flat dish and allow..! to

It is not unknown to find in placer gold workings a
vein nf gold quartz ore crossing the placer ground. Such
has boon found at Hoosier Pass, Summit county, Colo.,
whore at an altitude of 1400 feet an oxidized outcrop of
gold quartz ore followed through placer workings by
shaft and tunnel developed a paying lode, as well as
placer initio, on tho same claim.
During 1899 San Francisco received coal as follows :
From British Columbia 447,200 tons : coast mines, 710,600
tons (exclusive of coal received by rail from Mt. Diablo,
Tesla, Colorado and Utah); Australia, 130,600 tons;
Great Britain, 99,200 tons : Eastorn, 34,400 tons ; Mt.
Diablo, 50,000 tons; Tesla, 80,000 tons; Colorado and
Utah, 40,000 tons, a total of 1,592,000 tons. Southern
California ports received 187,000 tons. Australian New-
castle coal ranged in price during the year from $6.25 to
$7.50 per ton.
All steel used for boilers of steamships constructed
under Lloyd's rules is required to have an ultimate ten-
sile strength of not less than twenty-six tons, and not
more than thirty tons per square inch of section, and the
ultimate elongation must not be less than 20% in a length
of 8 inches. It is to be capable of being bent to a curve,
of which the inner radius is not greater than one and a
half times the thickness of the plates or bars after hav-
ing been heated uniformly to a low cherry red, and
quenched in water at 82° F.
Sec. 2319, Revised Statutes, U. S., says: "All valu-
able mineral deposits in lands belonging to the United
States, both surveyed and unsurveyed, are hereby de-
clared to be free and open to exploration and purchase,
and the lands in which they are found to occupation and
purchase, by citizens of the United States and those who
have declared their intention to become such, under reg-
ulations prescribed by law, and according to the local
customs or rules of miners in the several mining districts,
so far as the same are applicable and not inconsistent
with the laws of the United States."
In the Siemens-Halske method for treating the cyanide
liquors from the waste tailings or sludges produced in
cyanide gold extraction, and containing a very small
amount of gold, an extremely dilute solution of cyanide
is employed to dissolve the gold. This is afterwards
subjected to electrolysis, with iron anodes and thin lead
cathodes, with a current density of two-tenths of an
ampere per square foot. This results in an almost com-
plete recovery of the gold in an adherent form upon the
lead cathode. When the required amount of gold has
been deposited the cathodes are removed and the gold
separated by cupellation.
The decision by the Secretary of the Interior, Aug. 3,
in the case of Marborg of Colorado, in which it was held:
that an applicant for patent who has been adversed in
the court is not obliged, aftor the commencement of ad-
verse proceedings, to keep up the annual expenditure
under Section 2324, Revised Stats., U. S., in order to pre-
vent relocation and probable loss of his claim during the
pendency of such proceedings, and that the same rule is
applicable to protest proceedings before the land depart-
ment— is interpreted to mean that it removes the neces-
sity of doing annual labor on any unpatented mining
claim against which there is any litigation.
As BETWEEN cyanide and barrel chlorination process,
the greatest difference in cost after roasting lies in the
amount and value of chemicals used. The chemical cost
in chlorination would vary from 50 to 70 cents per ton;
in cyaniding from 25 to 45 cents per ton. While this
fragmentary statement would appear to indicate that
chlorination would be dearer, other elements, such as
coarser crushing for chlorination, and percentage of sav-
ing, would offset such implication. The difference would
require some space to explain, and as for comparison
that need no longer be instituted. The ore itself should
determine the process, and that can be best learned by
experience.
A method for determination of iron in ores is as fol-
lows: Digest 1 g. ore in 10 c.c. strong nitric acid,
adding 5 c.c. hydrochloric if the substance be found dif-
ficult to decompose. When decomposition is complete,
add, without removing from heat, 10 c.c. concentrated
sulphuric acid; boil till nitric and hydrochloric acids aro
completely expelled; remove from source of heat, and,
when cool, add 50 c.c. water; boil till all soluble sulphates
are in solution, and filter into a copper flask, washing the
filter thoroughly with hot water. To the solution in
flask add three strips heavy aluminum foil, free from
iron, and boil till the iron is entirely reduced to the fer-
rous state, which may be determined by ammonium-
sulpho-cyanate in the usual manner, when the solution is
ready for decantation, and titration with standard solu-
tion of potassium permanganate. If copper is present in
the sample, it will be found precipitated on the aluminum
and its percentage may be determined by either the
cyanide or iodide method, if required.
A cheap and effective dressing for a belt is tallow.
When a belt is pliable, and only dry and husky, the ap-
plication of blood-warm tallow, thoroughly dried in by
the heat of the sun or fire, will tend to keep the belt in
good working condition. The oil of the tallow passes into
the leather, serving to soften it, and the stearin is left on
the outside, to fill the pores and leave a smooth surface.
The addition of resin to the tallow for belts, if used in
wet or damp places, will be of service and help preserve
their strength. Belts which have become dry and hard
should have an application of neat's foot or liver oil mixed
with a small quantity of resin. This prevents the oil
from injuring the belt and helps to preserve it. There
should not be so much rosin as to leave the belt sticky.
Belts should not be soaked in water before oiling and
ponetrating oils should but seldom be used, except occa-
sionally when a belt becomes very dry and bard. It may
then be moistened a little and havo neat's foot oil applied.
For new belts a composition of tallow and oil, with a lit-
tle resin or beeswax, should be used. Prepared castor oil
dressing is good and may be applied with a brush or rag
while the belt is running. Belt dressings of any kind
must not be applied too liberally in the case of a new
belt, otherwise it is apt to stretch, making It very liable
to run out of line.
An ammoniacal cooler for preventing lire damp explo-
sions is made. On introducing into shot holes ammo-
niacal or hydrated salts, not explosive of themselves,
their volatilization under the influence of the detonation
is capable of cooling down the gases sufficiently to avoid
all ignition of fire damp, and, inasmuch as the salts pro-
duce disagreeable nitrous vapors, certain inoffensive sub-
stances, rich in carbon, for preventing the formation of
nitrous vapors are added to the salts. In practice the
powder or other explosive is inserted into the bottom of
the shot hole, and then, by way of tamping, a quantity
of ammoniacal cooler, equal to half the weight of powder
employed, is added on top of the charge, although the
result would be the same if the cooler were placed on the
bottom of the hole and the powder on the top. Inas-
much as the salts which constitute the cooler are hygro-
scopical, they are compressed into the form of cylinders,
which are covered with paper and carefully stuck, and
coated with melted paraffine, for preserving the salts so
long as the paraffined case remains intact.
Velocity is measured by the number of feet trav-
ersed in a second. Thus a cricket or base ball hit hard
travels about 100 feet per second, which is about the rate
at which a carrier pigeon flies. A golf ball may start at
150 feet per second, an arrow at 250 feet, a pistol bullet
at 750 feet, a rifle bullet at 1500 to 2000 feet. But the
energy of the blow delivered by a projectile when instan-
taneously stopped in its flight is proportional, not to the
velocity, but to the velocity multiplied by itself or
squared ; so that if the velocity be doubled the energy is
increased four fold. But the energy is directly derived
from the propellant. So that to double the velocity of a
bullet one must produce four times the energy, to obtain
which the charge must be increased four fold. And one
can not have energy forward without energy backward,
or recoil. Take a pistol with .750 f. s. velocity,
quadruple the charge, and give the new weapon four
times the length of the barrel for the gases to expand in,
one gets a rifle with twice the velocity obtained by the
pistol, or 1500 f. s. ; but one also increases the recoil to
such an extent that if a rifle were held like a pistol it
would fly back into the face of the firer.
A circular percussion table in operation at the Ar-
gent mine, Tasmania, consists of a cast-iron table 13 feet
in diameter, cjonvex in form, turned smooth on the sur-
face, and vibrated by cams worked by a shaft under-
neath. The separation of the minerals from the gangue
is by means of water currents supplied by a curved water
pipe, revolved slowly over the surface of the table, re-
ceptacles at the outer rim of the table receiving the sev-
eral grades of concentrates. The ore is fed onto the table
with water and runs in a curved direction toward the
outer edge of the table. On its way the stream is reduced
in velocity and depth to about one-third, owing to the
greater surface covered, causing a separation of the
lighter and heavier particles ; the former leave the table
at once, while the latter are further separated by passing
under the stream of water from the rotating curved wa-
ter pipe, which, assisted by the vibrations of the table,
with gradually increasing energy and velocity, separates
the various materials according to their specific gravity
and washes them into the rotating delivery receptacles,
and thence into circular troughs which collect the differ-
ent sorts. Daily capacity of this machine is twelve tons.
A Cigale, Utah, querist who asked some time ago,
" Is magnetism a separate and distinct force from elec-
tricity ?" impatiently asks, "How long does it take to
get an answer through 'Concentrates,' and why don't
you answer my question?" "Concentrates" humbly
confesses inability in this case as in others to successfully
answer the inquiry, hesitating to rush in where angelB
fear to tread. Magnetism is considered to be " a sepa-
rate and distinct force from electricity." Among points
of difference, magnetism, unlike heat, light or statical
electricity, affords no phenomena immediately addressed
to the senses. Those words "magnetism" and "elec-
tricity " are only words used to connect cause and effect;
convenient expressions to conceal our ignorance. We
give names to nature's forces, but can do no more.
' ' Electricity " is not a thing, but a force ; it is called static
electricity when stored up as idle, though then energy
ready for doing work ; while doing work it is called
dynamic electricity. The other invisible, intangible
manifestation that we call "magnetism" is "separate
and distinct " from electricity, yet creatable thereby.
The magnetic effect produced by electrical induction is
the seat and center of all our electrical industries, tele-
graph, telephone, power and light. Like heat, light and
electricity, magnetism is susceptible of being called into
action at any time when subject to the right tests. To
explain these manifestations of energy is a gift not
vouchsafed to any one. It may be that they are all one
force appearing in different forms.

The Boise (Idaho) Basin Mining
District.
Written for the Mining and Scientific Press
by Robt. Nye, E. M.
Among the famous old-time mining districts which
have recently entered upon a period of increased
activity, few have had a more interesting past than
Boise Basin. In the report of the U. S. Geological
Survey this district is called Idaho Basin, but Boise
Basin is the name by which it is known throughout
Idaho and the West generally.
Boise Basin includes the headwaters of Moore creek
and its tributaries, which empty into the Boise river
about 18 miles above the city of Boise. It is about 30
miles northeast of Boise, the nearest railroad station
and supply point. The gold-producing area of the
basin does not exceed 150 square miles. Its length
from north to south is 15 miles and its greatest width
about 13 miles.
Few districts have produced more gold in propor-
tion to its size. The best and most conservative esti-
mates of the production from 1862 up to the present
place it at $100,000,000. Unfortunately, no accurate
records were kept during the first ten years, when
the output was at the high water mark, and conse-
quently the estimates made can never be positively
proven. Of the total output, not over 5% came from
the quartz mines and the balance from the placers.
Gold was first discovered near the present site of
Pioneerville in August, 1862, and before the end of
the year the rich gravels near Centerville, Idaho
City, Placerville and Granite Creek had been found.
The reports of these discoveries soon spread and the
influx of miners was so rapid that in a few years the
basin had a population reported to be in excess of
40,000. As is usual with placer mining camps, the
greatest production was reached during the first ten
years. After that period the output and population
gradually decreased and reached its lowest ebb about
1896 and 1897. Since then, owing to the introduction
of dredgers to work the low ground which could not
be profitably worked by the old methods, and the
interesting of outside capital in some of the quartz
mines, a great improvement and increased activity
along all lines have occurred.
Idaho City, the county seat of Boise county, is 36
miles northeast from Boise, over good mountain roads.
Centerville, Placerville and Quartzburg are respect-
ively 8, 12 and 16 miles west of Idaho City. Pioneer-
ville is 5 miles north of Centerville. Idaho City and
Placerville each have about 500 inhabitants, while
the total population of the basin is probably 1600 to
1800. A daily stage from Boise reaches all the basin
towns, carrying mail, express and passengers.
Quartzburg, the end of the line, is reached in about
thirteen hours' ride from Boise. All basin towns are
also connected with Boise by telephone. Freight
from Boise is hauled to all basin points for from 65
cents to $1 per 100 pounds, depending upon the time
of year and the consequent condition of the roads.
The elevation at Centerville, the most centrally
located of the basin towns, is about 4200 feet above
sea level. The summits of the gently sloping hills
which comprise most of the area of the basin are
from 100 to 800 feet higher, while the higher peaks
of the chains of mountains surrounding the basin, and
forming the rim of it, are from 7000 to 8000 feet high.
The hills and mountains are almost completely cov-
ered with a splendid growth of pine, fir and tama-
rack, insuring a bountiful supply of cheap fuel and
lumber for many years to come. Over large areas
there is very little underbrush, and the grassy, tree-
covered hills present the appearance of an immense
park without a keeper.
The climate is unsurpassed throughout the world.
In summer the days are warm and the atmosphere
clear, dry and bracing. The nights are always cool
enough to make two or more pairs of blankets a com-
fortable covering. The winters are generally mild,
with a very heavy snowfall, the snow often lying 4 to
6 feet deep upon the level. The almost entire ab-
sence of wind prevents the snow from drifting and
roads are easily kept open. Snowslides are unheard
of, even in the precipitous mountains of the basin's
rim.
The geology of the basin is most interesting and far
from simple. The country rock is a soft, micaceous
gray granite, which decomposes rapidly upon expos-
ure to air and water. It has been referred to the
Archaean period, but some geologists find reasons for
considering it of a later period. The lower valley of
Moore creek and Grimes creek for several- miles
above its junction with Moore creek was filled with a
basalt flow which was contemporaneous with the
flows of the Boise and Snake rivers, and which oc-
curred in Neocene times. The present streams have
eroded their channels entirely through the basalt,
which is left as perpendicular cliffs on each side,
forming a good example of a canyon within a valley.
Occasional porphyry dikes occur throughout the
basin, and a large porphyritic belt extends from a
point about 1J miles southwest of Quartzburg in a
northeasterly course along the rim of the basin to
Grimes Pass, a distance of about 8 miles. Beyond
Grimes Pass it has not been traced, although it no
doubt extends some distance farther.
The gravels of the streams and their low, flat banks
were generally from 2 to 6 feet deep, and consisted
principally of granite, porphyry and quartz cobbles
and boulders and sand of the same material. Few of
the boulders are over 8 inches in diameter, and not
over 10% of them are over 4 inches in diameter.
From 10 to 60 feet above these stream gravels are
bars or benches of gravel of the same material and
character. Sometimes several of these parallel
benches occur one above the other. The stream
gravels and bench gravels were almost without ex-
ception very rich. In places the stream gravels
were worked, but as they were low and flat the bench
gravels were easier and more profitable to work, and
were attacked first, and the tailings from these
bench deposits, which have been for the most part
worked out, have covered large areas of the rich
virgin stream gravels to a depth of 10 to 40 feet. In
some cases the lower benches have been covered with
the tailings or debris from the higher workings, as
well as the original stream beds.
In places large deposits of auriferous gravel occur
several hundred feet above the creek beds. These
deposits, while like those lower down, no doubt indi-
cate a former position of the streams, and are un-
mistakably much older and are ascribed to the Neo-
cene period, while the stream gravels and lower
benches are Pleistocene. The gravel of these depos-
its is all rounded and much water worn. Besides
these former channels of the streams, many gulches
have been found to be exceedingly rich, the gold of
which was found in a few feet of sandy soil and angu-
lar gravel, which showed little signs of erosion. Such
gulches invariably lead up to some quartz ledge, and
most of the richest quartz mines of the basin were
discovered in this way, as few of them outcrop.
The stream gravels rest upon the granite, gener-
ally, but on Moore creek for several miles below
Idaho City, and for a short distance above, they rest
upon a soft, sedimentary deposit of sand and clay,
which the miners term false bedrock. This deposit,
which contains little or no gold, was doubtless laid
down upon the bottom of a large fresh water lake, as
it bears no signs of having been deposited in flowing
water. Smaller patches of these lake beds occur
near Centerville and Placerville.
One of the most interesting occurrences is that of
a heavy yellow sand that hangs back with the black
sand and gold in the sluice boxes. This has been
determined as monazite, and it is believed to be the
only place this comparatively rare mineral has been
found in the Western States. There is no doubt but
that it is an original mineral in the granite of the
basin.
Seldom have extensive placer deposits been more
easily and certainly traced to their source than in
this district. Quartz veins, mostly small but many
of them very rich, occur throughout the basin. Two
well-defined gold quartz belts, however, may be con-
sidered with some certainty as the principal source
of the gold in the placers. The first and largest is
closely identified with the porphyrite belt, which ex-
tends from near Quartzburg to Grimes Pass. The
veins occur in the porphyrite or near its contact
with the granite. In this belt lie the Ebenezer, Gold
Hill, Iowa, Morning Star and other well-known mines.
In the Gold Hill the pay ore was in places 40 feet
wide. The other belt extends from Gambrinus and
Illinois gulches, about 5 miles east of Idaho City, in a
northwesterly course several miles to the Elkhorn
mine on Elk creek. Every stream and gulch head-
ing in or crossing either of these belts has been rich,
and streams and gulches not crossing either of these
belts have carried little gold, except in cases where
an isolated gulch that was rich led up to a quartz
ledge which did not belong to either belt.
The water supply for hydraulicking is limited and
the season is consequently a short one, ranging from
three to four months. A few mines have water for
five or six months.
The old Plowman claim, near Idaho City, operated
by the War Eagle M. Co. , has the largest water sup-
ply, usually getting four to five months' run, with
over 2000 inches of water. Their mine is the best
equipped in the basin. They are using four giants
against a bank which is now about 100 feet high.
About two-thirds of the bank is gravel and one-third
clay. The clay caves off in large boulders, which
have to be blasted, many of them before they can be
handled. This is the only placer mine in the district
where blasting is necessary.
The only large tract of good gravel remaining near
Centerville is owned and worked by Oaks & Smith
and the Wong Sing Co. This ground, owing to the
abundant water supply and the absence of clay and
.cement, can be worked at a less cost per yard than
any ground in the basin.
The richest ground in the district, probably, is
that owned by Leary & Reed, near Placerville. Con-
siderable amounts of cement and a low head of water
reduce the production here.
A Boston company, under the management of Mr.
Kirkpatrick, is operating a good hydraulic plant on
Fall creek, and the Pioneer Gold Gravel Co. has a
large amount of ground near Pioneerville, which it
leases in small tracts. Besides those mentioned, a
large number of smaller workings add materially to
the total output.
The large profits made by some of the gold dredg-
ers in Montana and California caused a sudden de-
mand for good dredging ground, and the broad, flat,
debris-covered valleys of Moore, Grimes, Granite and
Wolf creeks received early attention. In 1897 and
1898 large tracts of these creek bottoms were pros-
pected and much of them found to be rich. The
abundance of water for dredging purposes, the ab-
sence of clay, cement and large boulders and the soft,
easily cleaned bedrock make it ideal dredging ground.
The Eisdon Iron Works put in one of their dredg-
ers on Moore creek for the Boston & Idaho Dredging
Co. , which has been operating seven to eight months
a year since 1898, and proved very successful. The
latter company last year built a dipper dredger of
their own design, which is now working satisfacto-
rily. The Boise Dredging Co., Bedrock Dredging
Co. and Bullion Dredging Co., all under the same
management, each have a dredger. Those of the
first two named ran part of the season of 1899 and
proved the value of their ground, but the dredgers
have been idle this season and will be largely rebuilt
before they run again. The boat of the Bullion
Dredging Co., built after the same design as the
other two, is not yet finished.
The natural conditions for dredging on all the
creeks named are practically identical, and experi-
ence has proven that all ground yielding over 6 cents
per cubic yard can be worked at a profit. There is
probably enough ground along these creeks to keep
six to ten dredgers busy for ten years each. The
dredging season is seven to eight months a year.
While the discovery of rich, free milling surface ore
in a number of quartz veins followed very shortly the
discovery of placer gold, very little thorough, sys-
tematic development of the quartz mines has been
done until very recently. In spite of this fact, how-
ever, a number of the basin quartz mines have good
records of production. The Gold Hill and Pioneer
claims, near Quartzburg, worked as one mine, pro-
duced $2,225,000 in a few years and the shaft is now
down only 425 feet. It is claimed that there was
good ore in the bottom level when litigation stopped
operations. The Iowa, in the same neighborhood,
produced over $200,000 before the War Eagle M. Co.
took hold of it a few months ago. It is now being
equipped with a modern 30-stamp amalgamation and
concentration mill, and a chlorination mill to treat
the concentrates. The Elkhorn mine, on Elk creek,
produced over $500,000, but recent work upon it has
proved unprofitable up to the present time. The
Illinois and Gambrinus mines, about 5 miles northeast
of Idaho City, are credited with a production of
$225,000 and $263,000, respectively, but are not now
being worked. Perhaps half a dozen other mines
have produced from $25,000 to $100,000, while the
number which have produced smaller amounts is large.
The veins occur in the granite and associated por-
phyry dikes, and their chief characteristics are gen-
erally similar. For the most part they are zones of
sheeted granite or porphyry, filled with many small
seams of quartz carrying free gold, pyrite, arseno-
pyrite and zincblende scattered through them. The
walls for some distance from the veins are usually
much altered. The rock of the veins and walls is
usually soft and heavy and requires substantial tim-
bering. The country rock is soft and, while drilling
and breaking easily, usually stands well and crosscut
drifts and tunnels seldom need timbering.
The surface ores are free milling, but below the
permanent water level, usually found at a short dis-
tance from the surface, the values often lie princi-
pally in the sulphides and a high percentage of ex-
traction cannot be obtained by simple amalgamation.
The present freight and smelter charges at the near-
est smelters amount to about $40 per ton, prohibiting
the shipping of any but high-grade concentrates or
ore. The almost entire absence of lead and copper
in the ores, and the absence of suitable fluxes in the
immediate vicinity, puts smelting out of the question.
The most promising process seems to be that adopted
by the War Eagle M. Co., previously mentioned, and
their work is being watched with a great deal of in-
terest by all mining men of the district.
While most of the few hydraulic mines now being
operated will continue to be profitable for many
years to come, no new discoveries of hydraulic mines
can be looked for. All new development must come
from the large areas of dredging ground and the
quartz veins. While no rush or boom is expected or
desired, work already planned and started insures a
steady growth and improvement.
Little has been written about this district, but a
large amount of valuable information about it can be
found in the monograph of Prof. Waldemar Lindgren,
entitled "The Mining Districts of the Idaho Basin
and the Boise Bidge, Idaho," and published as a part
of the Eighteenth Annual Report of the U. S. Geo-
logical Survey in 1898.
' Russia's production of petroleum during 1899 was
the greatest ever known and paid best. The revenue
of the Russian Government from the excise duty on
refined petroleum amounted to nearly $14,000,000 in
1899— an increase of $1,500,000 over 1898. Eight
years ago crude oil was selling at Baku at H to 2
cents per pood of thirty-six pounds. During 1899
the average price of crude oil was about 7 cents per
pood, and during the last two or three months the
raw material was bringing 9 to 10 cents per pood,
with a corresponding rise in the price of other pe-
troleum products.

Gas Engine Economy.
Although the gas engine has made rapid progress
during the last decade, and the improvements that
have been developed have increased both the effici-
ency of the engine and its steadiness of running, there
yet remains a Held for improvement that includes
within its bounds great possibilities. The gas engine,
as it stands today, is by no means the engine it is
likely to be a dozen years hence. It has many faults.
These are, indeed, counterbalanced by its many vir-
tues, and for that reason the faults are overlooked in
extolling its merits. There is nothing better than
competition to spur inventions and improvements,
and the rapidity with which the power-using public
is taking up the gas engine augurs well for its
future.
To begin with, the gas engine as built at present
has a terminal pressure within the cylinder averag-
ing about thirty-five pounds to the square inch. If
products of combustion are allowed to leave the ex-
haust pipe at this pressure, the resultant noise is so
great as to constitute an objectionable feature.
Therefore, the exhaust is led through a series of
tortuous passages in order to quiet it, with the result
that the back pressure in the engine is increased,
with a consequent loss of power in the engine. Al-
though the compound engine and the variable-stroke
engine have been tried and abandoned, the writer
believes that there is ample opportunity for improve-
ment in this respect. An increase in the expansion
would give at least 10% increase in power for the
same fuel consumption, when employing the compres-
sion pressures now in general use. There would also
be absence of noise, as the terminal pressure could,
in all likelihood, be brought to within four or five
pounds of that of the atmosphere.
It is not realized by every gas engine manufacturer
that the advantages of the multiple-cylinder engine
are numerous. In the first place, an increase in the
number of cylinders is conducive to steady running,
as is generally admitted. The decrease in the neces-
sary weight of the flywheel is not only of advantage in
the saving of iron, but it also reduces the friction of
the engine to a marked degree, and, consequently,
increases the mechanical efficiency of the engine. In
a multiple-cylinder engine there are opportunities for
balancing which are lost sight of by the majority of
designers, and much has been done in this line in a
hit-and-miss sort of way. There is much literature
on the subject of balancing, and very few writers
agree as to proper methods. In fact, the gas engine
builder quite frequently has derived an empirical
formula of his own which gives results that are, in
his estimation, good enough, but by no means per-
fect.
There is also a chance for improvement in the
handling of the water that passes through the water
jacket. In factory tests it has been found that the
best results were obtainable when the temperature
of the water of the water jacket was 150c Fahren-
heit, this temperature varying in different engines.
But the writer has yet to see a single gas-engine in-
struction sheet in which this fact is mentioned. In
fact, no attention whatever is paid to the jacket
water after the engine leaves the factory. Now, why
should this be so ? Is it because the gas engine is the
motive power for the ignorant or the indolent ? The
writer admits that this matter does not assume great
proportions in the engines of small dimensions ; but
the question arises : would it not pay to employ a
temperature regulator on the engine that would con-
trol the temperature of the engine cylinder by means
of the water supply ? It would be absolutely useless
to leave this regulation to the engineer unless the en-
gine were operating under a comparatively constant
load, for with a diminution of the load the water sup-
ply should be decreased, and vice versa.
The question of high compression is a matter that
is a puzzle to the average gas-engine builder. The
writer has quite frequently been asked for his opinion
on this question, and usually with an inflection that
showed plainly the questioner's aversion to increase of
compression pressures. And why this aversion ? The
answer is not hard to give. The gas-engine builder
who already has an established line of patterns and
has tools, templets, etc., which are adapted to the
particular designs which he has in hand, finds that to
increase the compression means a necessary
strengthening of his engine in almost every part. It
is notorious that the average gas engine is seldom
built too strong for its work, and an increase in com-
pression is, perhaps, a harbinger of frequent break-
downs. There is, however, no reason that when a
new design is contemplated it should not be so
proportioned that it can withstand the increased
pressure.
With increased compression comes the danger of
premature ignitions, commonly known as "back-
firing," and there is a limit to compression for each
fuel employed which depends almost entirely upon the
ignition temperature of that fuel. For this reason
compression can not be carried to so high a temper-
ature when gasoline is the fuel employed as when the
fuel is natural or artificial gas. Gases rich in hydro-
gen— as those made by the water gas process — are
also an obstacle to high compression. The compres-
sion of a charge of pure air and the subsequent intro-
duction of the fuel at the end of the compression is a
method that overcomes this difficulty, but is covered
with patents, and can not be employed by the gas
engine manufacturer without the payment of royal-
ties. The subject is one that has been given consid-
erable attention by a prominent firm of gas-engine
builders, and the results obtained indicate that the
subject is one worthy of consideration, and that an in-
crease in compression carries with it an increased
economy of fuel consumption.
A matter which appears to have but little atten-
tion from the gas-engine designer is the proportions
of the inlet and exhaust passages. These are too
frequently made much smaller than they should be,
and often without apparent reason. In a series of
engines recently examined by the writer, no regu-
larity of proportion was apparent, as the ratios of the
passages to the volumes of the cylinder and the piston
speed were the same in only a few instances. The
designer did not seem to realize that throttling the
air as it entered the engine would reduce the volume
of the charge, nor that an obstructed exhaust would
increase the back pressure on the piston. In several
cases the valve openings were ample, but the port
leading from the valve box to the cylinder was con-
tracted, although there was more than enough room
to have it made larger. There is another class of de-
signers who give both valve openings the same area,
while the usual excuse for this is that if the exhaust
valve is big enough the other is also; yet it seems to
the writer that it is a confession of inability to decide
what is the better size in either case. To make the
valves big enough is all well and good, but there is a
practical limit beyond which it is always foolish to go,
as to make the valves or passages larger than neces-
sary requires an unnecessary expenditure in the
manufacture. Fortunately or unfortunately, the
upper limit is not very often passed, and it is found
in practice that the engine could be much im-
proved by increasing the inlet and the outlet pas-
sages.
There is still another question that bears very
strongly on the economy of the gas engine, and that
is the question of load. All gas engines give their
best performance at nearly full load. There are but
few power requirements in which the engine would
run at its full load for the major portion of the time
it is in use. The engine is guaranteed to produce a
horse power on so much fuel per hour, and it does
very nicely when the load is that at which the engine
is rated ; but let the load fall off 50% or more, and
note the enormous falling off in economy. But how
avoid it ? The problem is nicely met by dividing
the load between several engines. Thus, if the maxi-
mum load is 50 H. P., install a 20 and a 30 H. P. en-
gine. When the load is one-half of the total and not
more than three-fifths, the larger engine may be em-
ployed. When the load drops below two-fifths of the
whole, the smaller engine may be employed, and when
the power requirement is too great for the larger en-
gine both may be used together. Of course, this plan
is not practical when the load is changing between
wide limits in a short interval of time, but there are
many cases where it may be applied. A plan which is
better adapted to the latter case, and where the re-
quirements for speed regulation are such as to per-
mit its use, is to employ a multiple-cylinder engine
and govern it by cutting out one cylinder at a time,
instead of having the impulses stopped on all the cyl-
inders at the same time. This plan is already in use,
and it is understood to be a success.
In all gas engines, and in gasoline and oil engines
especially, the combustion of the fuel is a point that
may be well looked after. Imperfect mixtures, es-
pecially those which are too rich in fuel, often result
in the discharge of unburned material into the ex-
haust passages. The best way to determine the state
of the mixture in the gas engine cylinder while the
engine is running is to place a small pet cock on the
cylinder in such a position that it opens directly into
the compression space. When this pet cock is open
and a part of the mixture allowed to escape at the
time of the explosion, the color of flame gives a good
indication of the proportion of gas in the charge. If
this proportion is about right, the flame will be a deep
blue, similar to that at the base of a. Bunsen flame,
while should the proportion of gas be too great the
point and the edges of the flame will be tinged with
orange. And this, by the way, is a very simple
method for determining the proper opening of the gas
valve.
While the maximum economy of the engine is ob-
tained when the engine is giving nearly all the power
that can be obtained frcm it, the point of least fuel
consumption lies somewhere just below the point of
greatest power. The mixture which will develop the
highest mean effective pressure does not of necessity
waste the least gas. It is, therefore, well to deter-
mine the point of greatest economy, and to so pro-
portion the engine that the load it is required to carry
is as nearly as possible at this point. — E. W. Roberts,
in The G-as Engine.
should be devised for raising the rock on a scaffold
and letting the contestants go up into it from under-

down holes in the hope of getting a piece of the
money, and will also give strangers an idea of what
mining is like.
The Copper Deposits of Southwestern Nevada.*
Written for the Mining and Scientific Press by E. Mccormick.
The existence of deposits of copper-bearing mineral
of some magnitude in southwestern Nevada has long
been known to the mining world, but the first at-
tempt at systematic exploration of any of these de-
posits is believed to be the series of mining operations
now being conducted by the Vulcan Copper M. & S.
Co., in Santa Fe mining district, Esmeralda county.
The Vulcan Co. own and are exploring three groups
of claims, namely, John L., New York and Parrot.
Their operations at the present time are concen-
trated upon the latter group, which comprises the
following claims : Kearsarge, Parrot, Phoenix,
Dewey, Bowler, Powell, Lena May, Nora K. and
Schley.
This group of claims is situated 5 miles northeast of
Luning, on the line of the Carson & Colorado R. R. ,
the workings being located in the mouth of a canyon
at an altitude of about 5000 feet above sea level and
some 700 feet above the plain or flat below.
The geology of this section is similar to that of all
the " basin region," the surface of which was formed
by the drying up of former great lakes. The country
rock is magnesian limestone, the mine being a contact
between the limestone on the north and porphyry on
the south. This eruptive rock has broken up through
the limestone and can be traced on the surface for a
considerable distance. One result of this disturbance
has been extensive Assuring, and through the bedding
planes ore solutions have circulated, replacing the
limestone in part with bodies of sulphides, which
afterward have become oxidized by the oxidizing and
hydrating action of atmospheric waters. As a con-
sequence we find the surface bearing zone consisting
of siliceous and magnesian gangue, impregnated and
coated with chrysocolla and malachite. Owing to the
metamorphic action following the intrusion of the
eruptive rocks, the magnesia of the limestone has
been converted to the silicate and as such is found as
a coating on the sides of the fissure. The surface
croppings, from all indications, are simply the result
of the solutions from the main fissure following the
shortest course to the surface.
The property has from the first been carefully and
systematically developed, the object being to ascer-
tain the full extent of the ore body and put it in con-
dition to be a steady producer. There are a number
of surface inclines, shafts and excavations on the
property, from which good ore has been taken and
now lies on the dump ready for shipment, as illus-
trated herewith.
A double compartment shaft has been sunk to the
300-foot level, and levels extended from same at the
100 and 200-foot points, cutting a shoot of ore 40 feet
wide that averages 5.22% copper, 3 ozs. silver and 1
oz. gold. At present the hoisting is effected by a
gasoline engine of the two-cylinder type, built by the
Union Gas Engine Co. of San Francisco, about 200
tons being hoisted daily.
For fuel supply for steam and smelting, the com-
pany has secured the coal deposits at Columbus, dis-
tance 40 miles from the mine, and are now exploring
same both with a view to their own consumption and
introduction into adjacent markets. With the blow-
ing in of the smelter and the successful issue, of the
Vulcan Co.'s enterprises, this hitherto neglected sec-
tion of Nevada should take on a more prosperous ap-
pearance.

Ventilation of Mines.
Talking of miners' drilling contests, the Telluride,
Colo. , Journal says this thing of drilling straight down
holes in every match is getting monotonous and is not
the drawing card that it was a few years ago. Why
not have uppers, roof and breast drilling ? This is
what will test a miner's skill. Not one hole in 1000
in mining is a down hole. Next year some scheme
W. E. Mead of Ward, Colo., tells the Miner that it
is simply a matter of timbering to have good air in
the breast of any tunnel or in the bottom of any shaft,
as well as through every drift and stope in any mine.
It will cost a little more, but not nearly as much as
will be gained by the extra work obtained from men
working in good clean air instead of air charged with
powder fumes. Motion in air is caused by difference
in pressure, and this can be obtained by heat or by
some artificial means. Box up the skip or cage way.
and the travel of the skip or cage will clear the
'bottom of the shaft, acting like the sucker in a pump.
If one has a tunnel of any considerable length, make
it double track and partition between the tracks;
run the cars up one side and down the other, and
have clear air at the breast. If a fan is used, have a
suction fan; it will draw out the, gases. A blower
only mixes these gases up; it does not remove them.
If the air hangs dead in the bottom of the shaft, hang
a fire pot in the air shaft and the trouble is instantly
removed. The difference in work obtained from
working in clear air over air that is foul is frequently
50%, while it is merely a matter of lumber partitions
and bulkhead to ventilate every part of a mine,

Power Generation.
There is no question of greater importance at the I
present moment to those engaged in the management I
of our manufacturing industries than that of power ;
generation. The supremacy which the steam engine j
has long enjoyed is now assailed from two sides. The
water turbine and the gas engine have become dan-
gerous rivals.
During the past ten years a most remarkable de-
velopment of hydraulic power has been taking place
on the continent of Europe in France and Germany,
and in America at Niagara.
The aggregate amount of power at the present
date generated from falling water forms no inconsid-
erable portion of the total power utilized in manu-
facturing industries; and two years ago it was esti-
mated by the author to be between 236,000 and 350,-
000 H. P.
On the other hand, gas engineers have been busily
engaged in working out the problems presented by
large gas engines and by the utilization of the waste
gases of blast furnaces.
Gas engines up to 650 H. P. have been built, and
have worked smoothly and economically; while at
Seraing in Belgium and at other places the blast fur-
nace gases have, been utilized for driving the engines
which supply the blast.
The question, therefore, which the engineer now
has to settle when deciding upon the site and locality
for a new factory, or when deciding upon the system
of power generation to adopt for extensions of the
old, is no longer so simple as when only one method
of power generation in large units was open to him.
It is no doubt true that the choice between the
three possible sources of power is one which in many
cases will be settled purely by local considerations;
and the proximity of a large waterfall or of an ex-
tensive coal field to the factory will be held to point
to the turbine or to the steam engine as the most
economical power generator. In a great number of
cases, however, especially when the decision of the
engineer covers the choice of a site for the factory,
the problem is capable of no such easy solution; and
the most economical source of power can only be de-
termined after an exhaustive study of comparative
costs data.
The aim of the writer in the present paper has
been to collect and arrange in comparable form some
of the more important figures beariDg on the cost of
power generation.
(Tables I to VI in original article contain details of
sixty-five actual or estimated costs of steam, water
or gas power per H. P. year of 8760 hours.)
Taking the best figures of each of the three sources
of power dealt with above, and bringing them all to
a common basis of comparison, namely, the cost of
the E. H. P. year of 8760 hours, the author obtained
the figures given in the following table:

POWER.

The figures in the table support the opinion, now
generally held, that water when developed without
excessive capital expenditure is the cheapest source
of mechanical or electrical energy. When, however,
the hydraulic engineering expenditure has been
heavy, or when the power after generation has re-
quired to be transmitted over long distances, the
margin between the relative costs of water and
steam power is greatly narrowed, and in some cases
disappears.
Electrical energy generated by falling water is
costing more at Rheinfelden, at Zurich, and at Buf-
falo than it would cost in South Lancashire if gener-
ated by steam power in large units, and the margin
between the actual charge for power at Niagara
and the estimated cost of steam power in large gen-
erating stations in South Lancashire is only 12s Id
E. H. P. year.
In this connection it is interesting to note that the
charge for electric power in Buffalo is 13s 6d per
E. H. P. year higher than at Niagara ; and the ex-
cessive charge to small consumers in the same city
(£25 lis per E. H. P. year) would seem to indicate
that the cost of transmission between Niagara and
Buffalo represents at least 20s per E. H. P. year on
the power sent into that city.
Turning now to a consideration of the relative posi-
tion of gas power, the question of the practicability
of large engines may be taken as settled. If they do
not cost excessive sums for maintenance and repairs,
large gas engines, in conjunction with coke ovens and
blast furnaces, may entirely alter the present posi-
tion of affairs ; and the new industries which at pres-
* J. B. C. Kershaw; condensed.
ent are being established in the neighborhood of water
power stations may find themselves in severe compe-
tition with similar manufactures carried on in the
coal and iron districts of the older manufacturing
countries.
It has been calculated that 2,000,000 H. P. is annu-
ally wasted in the gases issuing from the blast fur-
naces of the United Kingdom. If these waste gases
could be industrially utilized in the manner suggested
we should to a large extent be compensated for our
lack of natural water power.
But blast furnaces demand coke, and coal beds are
exhaustible, so that even if this source of mechanical
and electrical energy be tapped it can only postpone,
but not avert, the final triumph of the waterfall and
of the turbine.
Use Made of Some Metals.
With lead by far the greater portion is converted
into white lead, red lead and orange material, which
are used as pigments of paints, distributed over
great surfaces in such thin coatings that their me-
tallic contents is practically never recovered. A
good deal of lead is manufactured into sheet, and a
considerable proportion into bullets, shot and other
projectiles; and, though still remaining in a metallic
form, it is so widely distributed in use as to cause it
to be irrecoverable in the form of scrap. A portion
of the lead product used as sheet lead and pipe does
come back into the market, but the portion of lead
used in these ways is comparatively small as com-
pared with the other uses of the metal.
The consumption of zinc is largely in galvanizing
steel or iron sheets, in the manufacture of brass, as
sheet zinc, and as the oxide of zinc used as a pigment
in paint. That portion of the metal which is used in
galvanizing is distributed as a thin covering over a
large surface of iron, and the metal is entirely lost
in the oxidiziDg and general disintegration of the zinc
sheet. It has never been attempted to recover the
zinc from galvanized iron. Zinc which is manufac-
tured into brass, in the proportion of one-third zinc
to two-thirds copper, remains in a permanent form,
which is often available for new use as scrap brass,
and, next to iron and steel, is the largest commodity
in the scrap metal market.
The major portion of the tin product of the world
is used in covering tin plates. Ordinary tin plates
carry 1J% to 31% of tin. Many attempts have been
made to recover this tin from old tin scrap, but no
considerable amount of metal has thus returned to
the markets of the world as recovered from tin scrap
up to the present time.
Of the common metals next to iron and steel,
copper is the one which is used to the largest extent
in the metallic form, only a small proportion of the
production being utilized in the salts of copper, blue
vitriol (the salt of copper used in galvanic batteries)
being the principal salt of the metal sold in the mar-
ket. The great uses of copper are in the manufac-
ture of brass, of which it forms a two-thirds compo-
nent part ordinarily, and in electrical conductors and
in the form of sheet used in roofing, the bottoms of
cooking and other utensils, in the manufacture of
pipes to be used where a considerable amount of
elasticity and pliability are required. The propor-
tion of scrap copper for sale in the market is greater
than that of any other metals, with the exception of
iron and steel; but the total amount of old copper
offered for sale is comparatively insignificant com-
pared with the total copper production.
Demand for Mining Machinery
Dealers in mining machinery report that the out-
look for a first-class fall trade was never before so
good. Within the coming month mining men who
have been busy all summer with development work
will begin to arrive in this city with their plans for
future improvement. Mining is necessarily a pro-
gressive industry. No practical miner would put a
$30,000 first-motion hoist over a 10-foot prospect
hole, and, on the other hand, no one who has a fair
idea of economic principles will continue to hoist ore
from a depth of 250 feet with a windlass or whim.
The result is that the almost constant purchase of
machinery is necessary. The machine that, was
ahead of the requirements last year may be behind
to-day. These purchases are generally made in the
fall and winter, after the summer's work has shown
what is necessary, and there is no more certain indi-
cation of a prosperous and successful season than a
brisk trade in mining machinery. Conditions are
more favorable to buyers than they were a year ago.
Then every factory in the United States was crowded
to its utmost capacity and the miner who succeeded
in getting his order filled within four mouths was for-
tunate. This condition has been greatly improved
during the last year. Nearly every prominent manu-
factory of mining machinery in the country has had
its capacity increased. The remarkable increase in
the demand for mining machinery during the past
three or four years has induced most of the leading
firms to create special mining departments, and one
firm has found it necessary not only to build a new
factory in this country, but to establish a branch fac-
tory in Canada for the special purpose of supplying
Canadian miners without straining the capacity of
the main establishment. All of these improvements
in the manufacturing situation have materially re-
lieved the pressure so that miners who place their
orders now have a reasonable assurance of prompt
service, and very many who have been holding off
and getting along as well as they could with their old
machines are now putting in their orders.^-Denver,

A Large Enterprise.
At Sault Sainte Marie, Ontario, P. H. Clergue
and associates have an extensive project. A few
years ago, at the lower end of Lake Superior, they
cut a canal that furnished 10,000 H. P. for electrical
energy, but when they wanted to sell the power they
found no takers. To save the original investment
they were forced to change their policy, utilize it
themselves, and find a means for development. The
first enterprise was a spruce pulp mill, now making a
product that sells for $900,000 a year, and fixes the
price for paper pulp.
Mechanical pulp is worth $30 a ton, sulphite pulp,
wood treated chemically, is worth more ; the com-
pany decided to make this also, and the largest sul-
phite mill in the world is nearing completion, for
sulphite pulp sulphur is necessary. The Sudbury
works of the Canadian Copper Co. are expected
to furnish considerable sulphur as a by-product.
Sudbury is 100 miles from the Sault, and produces
a good deal of nickel. The nickel ore mined there
is nickeliferous pyrrhotite, containing nickel, sul-
phur and iron. At the matte furnaces of the
Canadian Copper Co. they are saving nickel, but the
sulphur and iron are not utilized. Mr. Clergue
thinks he can make a commercial product from
roasting pyrrhotite. His company have bought a
nickel mine near Sudbury for the sulphur, and are-
building the Manitoulin & North Shore Railway to
and through the nickel belt and on to Georgian bay.
With the extraction of sulphur from the pyrrhotite,
there is left a ferro-nickel ore, with possibilities for
the manufacture of nickel-steel. The company pro-
poses the utilization of this ore, and claims to be able
to accomplish reduction on an economical scale of
ores of iron into steel by electricity. Furnaces are
devised that to the extent of a five-ton unit have
smelted this soft, high nickel ore into nickel-steel,
sufficient iron ore being added to the mixture to make
a hard steel. The nickel percentage of their ferro-
nickel was so great that the resulting steel was very
soft, it being a peculiar feature of nickel that a per-
centage of about five or six makes the alloy soft,
while a percentage of three or thereabouts makes an
armor plate. The company has a machine shop and
the hard cutting tools used there are made of its own
nickel-steel smelted in its own furnaces by electricity.
The plans for the ferro-nickel works propose 100
furnaces of five tons daily capacity each.
To the company the Dominion and Ontario govern-
ments have given grants of money and lands. The
lands include 1,650,000 acres for a road running from
the Sault to Missinable on the Canadian Pacific Rail-
road, 150 miles northerly. The Dominion has given
cash subsidies for an extension of the road to Hud-
son bay in five years an additional grant of $500,000
and 1,250,000 acres have been offered. The lands of
these grants are not to be selected in one bunch, but
within a reasonable distance of the lines of the road,
in small blocks. To avail itself of this privilege the
company has timber cruisers, mineralogists and
geologists traversing that region, each party of two
men accompanied by Indian guides and canoemen,
selecting timber lands, running out geological forma-
tions, verifying and correcting old surveys ; the
grants will be selected under their reports.
Clarke & Co. of Toronto formulate an extensive
program, the details of which remain to be confirmed.
If two clocks on the same shelf have their pendu-
lums adjusted to swing in exact unison, and one of
them is set to running, in the course of time the other
will start up in sympathy. Each sound impulse
caused by the vibration of the pendulum of the clock-
that is running is communicated to the other pendu-
lum. Each successive impulse adds to the swing of
the sympathetic pendulum, which began in an ex-
ceedingly small way at the very first stroke of the
other pendulum, and this goes on till the sympathetic
pendulum is making its full stroke. So with sympa-
thetic tuning forks. Each air wave that is sent out
by the initial fork strikes the other fork and causes
at first a slight vibration, which accumulates, be-
cause each successive air wave strikes the sympa-
thetic fork just at the end of its swing and works in
harmony with the natural tendency of the fork to
vibrate. The result is a co-operation. Each helps
the other. How much better it would be for the
world if men could pattern after this law of physics.
A New York paper says that in that city, located
on one of the narrow side streets down town, is a
factory in which are made every year more than
$100,000 worth of divining rods for use in finding hid-
den treasures. From this factory alone are turned
out and sold each year almost 5000 fake rods, which
means that in the rural districts within 200 or 300
miles of the metropolis are found every twelve months
that many gullible and ignorant people. These rods
are sold at from $15 to $35.

This company, composed of the five names above,
put up $25,000, purchased the Linda dredging outfit,
brought out from Boston, and went to work on the
Yuba river at Oulsley's bar. Joseph Tryon was
superintendent. The company worked about six
weeks on the bar, but the large rocks encountered
made the operation impracticable. Mr. Paul says
the company had 100 shares in it, each one of the five
owners having twenty shares. Each held and lost
all he put in, although before getting to work they
were offered $100,000 for all the stock, and refused it.
Russia supplies 94% of all the platinum manufac-
tured, and the Ural platinum industry may be said to
monopolize this metal commercially. Up till quite
recently this industry was completely dependent
upon some few foreign firms, with offices in London
or Hamburg and agencies in Russia. There are no
installations for handling the metal in Russia, and all
the crude platinum has consequently to be trans-
ferred to the firms referred to. The export of crude
platinum is, however, likely to soon cease altogether,
inasmuch as the syndicate of foreign capitalists which
has secured the platinum working establishments of
the Ural has erected two refineries at Jekaterinen-
burg The difference in value between crude and
refined platinum is about , 100%— 9000 to 10,000
roubles per pood, and 15,000 to 20,000 roubles. The
syndicate has also secured the crude platinum held
by Count P. P. Schuwalow and M. P. P. Demidow, so
that the syndicate will handle about 300 poods of
crude platinum annually. About 75% of the whole
production goes to America, with which country the
syndicate intends to enter into direct relations. It is
expected that the business will prove a remunerative
one. — American Manufacturer.

Cold Sands of the Snake River, Idaho.
In a paper on the " Hydraulic Pumping Plant on
the Snake River, Idaho, for Power, Irrigation and
the Treatment of Gold Sands," by John Birkinbine, at
the Washington meeting of the American Institute of
Mining Engineers, he notes the existence of free gold
in large quantity, but generally finely comminuted
(much of it being float gold), and that the Snake
river is actively exploited by dredgers and ground-
sluicing. The most desirable deposits of auriferous
sands are either above the river level, and unwork-
able, except by hand labor or by water artificially
elevated, or are in bars in the bed of the stream,
from which the sand and the water for washing it
must be raised by mechanical power. Close to
American Falls the territory adjoining the shores is
worked at a number of places, the material being
handled by scrapers drawn by horses and treated in
crude ground sluices with satisfactory results. The
present operations are confined to bars, or to locali-
ties where the stripping is slight, because the ma-
terial must be handled by animal labor or by steam
dredgers, which latter must pay from $4 to $6 per
ton of coal, delivered at the dredgers, of which nearly
sixty dredgers are reported at work on the Snake
river. Electric power developed at the American
Falls may possibly be conveyed to operate dredgers
at other points on the river, at rates which, while
profitable to the generating company, will permit a
reduction in the cost of operating the dredgers.
With water delivered to the top of the banks, and
used through pipes and nozzles, this territory yields
more gold at smaller cost per ounce.
Mr. Birkinbine calculates that three sluice-heads
of water, supplied by the 750 cubic feet per minute
furnished by the present plant, should each wash at
least 500 cubic yards per day when in operation —
i. e., move 1500 cubic yards per twenty-four hours;
26 cubic feet of water would, therefore, be required
per cubic foot of material washed. But even if a
more liberal supply of water must be pumped, this
would permit the moving of the material to sluices at
a cost below that required for dredging, and much
below that which prevails at the active ground-
sluicing operations.
The project is to use the irrigation ditches for con-
veying water to the gold diggings; but it may be
found advantageous to attack some of the auriferous
sands with water which need not be elevated as high
as for the ditches, and greater service can thus be
secured from a given river volume, applied as power
to pump the water for washing. If, however, gold
washing is carried on as an adjunct to an irrigation
system as planned, there is opportunity for special
saving in each department.
All of the gold in the Snake River district is finely
comminuted, and the magnetic iron sand associated
with it is also quite finely divided. It may be found
practicable to withdraw the iron sands by magnetic
separators, leaving a smaller volume to be subjected
to amalgamation.
Man, Muscle and Coal.
The fact that the new steamer Deutschland devel-
ops power at the rate of 1 H. P. hour for
each one and one-half pounds of coal consumed has
been said to be the greatest development of marine
boilers and eDgines. Static power producers have
done even better than this. At the Edison power
plant power has been developed at the rate of 1 H. P.
hour for each pound of coal consumed. A few equa-
tions from this starting point would lead to :
One pound coal equals 1 H. P. hour.
Two thousand pounds coal equals 2000 H. P. hours.
Two thousand pounds coal equals 200 H. P. days of
ten hours each.
One H. P. hour equals 14 M. P. hours.
Two thousand pounds of coal equals 2800 M. P. days
of ten hours each.
Two thousand pounds coal equals 9 M. P. years of
311 days each.
Value of 2000 pounds coal, excluding transporta-
tion, $1 to $10, according to locality.
Annual production of coal in the United States,
240,000,000 net tons.
Potentiality in man power years of 240,000,000 tons
of coal, 2,160,000,000 years.
Estimated number of male producers in the United
States, 20,000,000.
Ratio between 20,000,000 male workers and the
potentiality of 240,000,000 tons of coal, 1 to 108.
That is to say, 20,000,000 workers, without the aid
of coal, would have to labor 108 years to develop a
force equal to the potential energy of the present
annual production of coal in the United States.
Transition to Electric Poww.
With electrical distribution of water power only a
small space is necessary for the few large wheels and
dynamos that absorb the entire energy of the water.
Millsites, instead of being confined to a little land
along the banks of a river or canal, at once expand
to include the territory within 5, 10 or a greater
number of miles of the generating plant. This ex-
pansion of service area affects the number and the
character of power users. The number of industries
is limited only by the water available, and the ca-
pacity of each may be either great or small. Since
millsites have come to include all the land within a
long radius that is not required for other purposes,
the opportunity to buy cheap power has only a slight
influence on rents. Almost the entire saving in the
cost of power is thus free to be divided between the
water company and its patrons.
A distinct feature of electrically distributed water
power is the advantages it offers to manufacturers of
small and medium capacity. The consumer of 100
H. P. will probably have to pay somewhat more per
unit than the consumer of 1000 H. P. ; but the differ-
ence in rates will represent only a small fraction of
that in cost which would result were a separate
water-wheel installed for each case.
It is interesting to note that the results with elec-
trically distributed water power are different from
what some have expected. Electric energy, it was
claimed, for example, would go great distances to
the factories. As a fact, however, the factories have
gone great distances to the electric power. Loca-
tion and other advantages being equal, it is found
more economical to move an industry once than to
move a large amount of energy to it over a great dis-
tance daily. Increase of transmission voltages may
reduce, but it can not eliminate the costs and losses
of electric conductors. For very long transmissions
the fixed capital in conductors, pole lines and the
extra machinery necessary for the several trans-
formations bears interest, per delivered unit of en-
ergy, that might well cover the entire charge for
such unit near the generating plant. In the future,
as at present, long-distance transmission of electric
power must be the exception for special cases and
transition, to within a few miles at most of cheap
sources of energy, the rule for the great majority of
industries served. — A. D. Adams in Cassier's Maga-
zine for October.
Ore Thefts in Colorado.
Much of the high-grade ore that is stolen from the
rich mines of Cripple Creek is marketed, it is
asserted, in this city, says the Denver,Colo. , Post. The
managers of the mines that have suffered the most,
according to a heavy stockholder in one of the com-
panies affected, have evidence that certain ore buy-
ers are getting rich from the stolen stuff, obtaining
it at half and sometimes less than half its value.
The mining managers estimate that about 25% of
the employes of the mines in Cripple Creek are en-
gaged in systematically pilfering high-grade ore.
They use many methods in getting the rich specimens
out of the mines undetected. The scheme of com-
pelling the men to change their garments before
going down the shaft to work is regarded as the only
solution of the problem, and, though it may inflict in-
dignities on the honest miners, the managers think
they will submit rather than draw suspicion upon
themselves by refusing.
Men interested in the companies that have decided
to compel men to not only submit to being searched,
but to change their clothes after coming from the
underground workings, say they do not know of any
other remedy than the action taken by the com-
panies.
They say : ' ' The miners will no doubt protest, but
think the fair-minded and honest ones will see the jus-
tice of the proceedings. You say that the men will
object to being compelled to have two sets of clothing
at the mines ? Well, we believe an amicable agree-
ment can be reached on that subject without dif-
ficulty. The mines should and, we believe, will be
ready to furnish the miners with their working
clothes. Few people have any idea of the extent of
the theft of ore. The Elkton Company estimates that
enough ore is stolen annually to rob us of one dividend
—$75,000.
" Five of the Elkton employes were arrested re-
cently for stealing ore. Twenty odd others who were
known to be implicated in the thefts escaped. On the
person of each miner arrested was found, on an aver-
age, $40 worth of ore. One of the men arrested has
been a trusted employe of the Elkton for years, and
his arrest was a great surprise to the management
of the mine.
"Now, the question that arises is: whether the
stockholders or the miners, who are paid their wages,
are entitled to the profits of the mines ?
' ' In this office a miner recently told us that he had
seen a letter from a Cripple Creek miner, who was a
foreman and had forty or fifty men under him, to a
Denver assayer, asking him if he could handle, so that
no questions would be asked, ore in car lots. The
letter, our informant told us, offered the Denver man
50% of the value of the shipment for doing what he
was asked."
That ore has and is being stolen in large quantities
is admitted by the miners, who say that a few men
working together have been heretofore able to make
profits by their thefts. The taking of rich and small
specimens from the mines is easily accomplished. The
miner takes it in his dinner pail, the band of his hat,
his shoes; but the most favored method has been by
the use of belts, concealed under the shirt. These
belts hold about ten pounds of ore, and only ore val-
ued at $1 per pound or more is taken.
The wholesale stealing is also done in various ways.
The ore sorters throw pieces of the richest stuff far
out on the dumps and pick it up at night ; but the
favorite method is by putting large chunks of
rich ore in the buckets that bring up the waste and
barren rock. The buckets that contain valuable ore
with the refuse are marked, and the men on top, see-
ing the mark, dump the bucket where the valuable
rock may be easily picked up at night.
The greatest difficulty the ore stealers have to con-
tend with is in disposing of the ore they have ac-
quired. In some instances it is sold with the under-
standing that it is stolen; but the favorite scheme is
to carry the ore to some friend who is operating a
lease and have him send it out with his shipment. Of
course, if there is no other way out of it the leaser
pays to the owners of the property which he is oper-
ating a royalty on the stolen stuff and in this way
covers up the tracks of his friend.
On the Use of Compressed Air.
The following is an abridgment of a paper on " The
Practical and Economical Points in Using Com-
pressed Air in Connection with Pneumatic Tools,"
read by J. L. Pilling of Chicago before the Franklin
Institute :
It has been my privilege in connection with my avo-
cation to visit about all the establishments where com-
pressed air is used in the United States, and, without
contradiction, I will say that, with few exceptions, I
have not seen a properly constructed air plant in my
travels.
The theoretical points of air compression have been
understood from time immemorial, but the most essen-
tial, practical and economical points which are in de-
mand to-day have not been touched upon, so far as I
have been able to ascertain, which fact is proved by
the observation cited in the first paragraph.
Compressed air will go as much below its normal
temperature in expansion as it goes above it in com-
pression ; therefore, the larger the exhaust port and
shorter the exhaust passage, the less liability of icing
up the tool.
Air Compressors. — Air compressors are as near
perfect as we may expect to see them for years to
come. The trouble lies not in compressor, but the
manner in which the compressor is connected to the
receiver, and taken therefrom. A receiver is not for
an accumulation, as many think ; only at the third
stage. First, it is for condensing surface ; second,
to take care of the pulsation of the compressor ;
third, for an accumulation.
An Upright Receiver. — By all means connect dis-
charge pipe from compressor near the top of the re-
ceiver ; take the outlet to the main line, about one
foot from the bottom of the receiver. Have the re-
ceiver so placed that the outside atmosphere can cir-
culate around it. Have a blow-off cock with a very
short connection at the bottom. If conditions are
such that a horizontal receiver must be used, connect
discharge from compressor on top of receiver at one
end ; connect outlet to main line at the other extreme,
but as low as possible, as long as it is above the fore
and aft line of the receiver.
Why ? On a clear day there are eight grains of
water to a cubic foot of air, and foreign matter in
suspension. Through the compression heat is gener-
ated. Heat will always rise. As long as air is above
its normal condition in temperature the moisture and
ingredients are in suspension. Moist air is a friction ;
moist steam is a lubricant. It will, therefore, be
readily understood what a receiver is for, and why it
should be connected up as I have already stated.
If, under these conditions, the air is still warm as it
leaves the receiver, then the receiver is not large
enough, or the compressor is too small, or both. (It
is often well to place another receiver adjacent to
where the most air is needed.) This argument will
hold good even if an intercooler is used, as on a com-
pound compressor. Precipitate the moisture in your
receiver ; that is what it is for. By so doing, you will
have no trouble with your main line freezing, and you
will obtain better results from your pneumatic tools,
which are as finely constructed as any piece of mech-
anism on earth. Treat them as such ; give them good,
dry air ; increase their efficiency by so doing, and les-
sen their repair bill.
Diamond Drill Work.
The British Columbia Minister of Mines proposes
the exploration of the metalliferous country of the
Kootenays by a government diamond drill. The cost
of a plant to bore 1200 feet would be about $5000; the
cost of working should be under $4 per foot. Accord-
ing to statistics from various parts of the United
States, the cost of boring twelve holes from 200 to
800 feet in length each, totaling 5957 feet, is $14,-
839.62, or $2.49 per foot. This included labor, super-
intendence, bits, repairs, water, extras, freight,
traveling and carbons. In northern Michigan, two
holes totaling 634 feet, two 360, six 1350, two 611, six
1091, or eighteen holes totaling 5048 feet, cost $2.60
per foot in very hard ground. In Colorado 567 feet
were bored at 44 cents per foot. The cost depends a
good deal on the length of standpipe used. The
smaller drills suggested would be worked either by
hand or horse power.

New Developments in Jigging.
Some notice is being made of the concentrating
works at Great Palls, Mont., where a new departure
has been made from the old system of jigging.
R. H. Richards, in his Cycle of the Plunger Jig,
enumerated and discussed the law of free settling
particles ; the law of hindered settling particles ;
the law of acceleration, and the law of suction. Ac-
cording to Rittinger, the law of free settling parti-
cles (which he calls the law of equal settling particles),
and the law of acceleration, are those which deter-
mine the separation of ore from its gangue. The
Canadian Mining Review instances that, in accord-
ance with this view, the best results should be
obtained when the ore was sized, and, consequently,
the mills of Germany and other European countries
introduced a system of close sizing before jigging,
which has been largety copied in America, but which
gave rise to a great deal of criticism, and was finally
abandoned by the most progressive mill men on this
side of the Atlantic. An experimental investigation
by Munroe of Columbia University, New York, estab-
lished a third law of hindered settling particles, by
showing that particles of ore falling en masse, as
actually happens in the bed of material on the jig
screen, are impeded in settling by falling through
interstitial spaces, which is equivalent to their fall-
ing through narrow vertical channels of circular
cross-section. As the interference increases with the
size of the ore particle relatively to the diameter of
the interstitial space through which it falls, it is evi-
dent that small particles of heavy ore, which would
be equal settling with considerable larger particles
of gangue, will enjoy a superior opportunity of being
separated and saved. This conformed to recent ex-
perience in actual milling operations and explained
the advantages which had been observed to follow
the jigging of ore previously classified with hydraulic
classifiers. The classifier accordingly superseded
the trommel, and close sizing before jigging was rele-
gated to the past. In other respects there was no
material difference between European and American
practice. A jig, consequently, while giving a re-
markably clean product, could not be crowded with-
out throwing large quantities of ore off with the tail-
ings, and any increase of speed produced the same
result. The speed was determined by velocity of
rising current needed to lift the particles of gangue
which would be equal settling with the smaller ore
particles left in the classified product fed to the ma-
chine. Here was its limitation, closely and accurately
confined, and the tendency of most mill men was to
force through a larger tonnage than that for which
the jig is calculated, with the inevitable result of loss
of values.
It is to be noted that this limitation was fixed in
accordance with the theory of particles falling in
water after having reached the period of a uniform
rate of fall, that is, after the resistance has increased
with the increasing velocity of the particle until it
counteracts the normal acceleration due to gravity.
Prom this it follows that the jig stroke must
be relatively long to allow the particles to reach
this period of uniform rate of fall. According to the
practice built up from this theory, the length of
stroke for ore particles A inch in diameter would be
from 2 inches to 21 inches, repeated about eighty
times a minute. A stroke as short as J inch would
not be used with particles larger than 1 m.m. (= 2XS
inch), at a speed of not over 125 strokes per minute.
Only with jigs for the finest sands, material such as
is now concentrated on vanners and washers of the
Wilfley type, were short strokes of from J to I inch,
and speeds of from 200 to 350 strokes per minute,
employed.
Attempts were often made to increase the speed,
but the resultant losses were so great that the mill-
men hastened to retrieve what was looked upon as
an error, and so the possibilities of doing good work
on relatively large sizes of sands at very high speeds
were not discovered. This is the peculiarity of the
practice inaugurated by W. J. Evans at Great Palls,
which, the Review asserts, has proven so successful
that the system of high speeds and short strokes will
be introduced into the 6000-ton concentrating plant
being erected at Anaconda, Mont. At Great Palls
ore crushed to pass a lj-inoh mesh screen is jigged
with 180 strokes per minute, 1} inches long, and
other smaller sizes in proportion. In general the
length of stroke should be approximately the same
as the diameter of the maximum size of ore particles
fed, making due compensation for the relatively
greater resistance to falling in water on the part of
very small sizes of grains. The result of this is to
take advantage of the acceleration before the period
of uniform velocity of fall has been reached, and thus
to assist gravity many times a minute. Mr. Evans
would dissent from this way of stating the matter,
his view being that jigging depends less on gravity
than on frequent assisting of gravity by quickly ap-
plied suction at the moment of reversal of motion.
This is a widely different thing from the so-called law
of suction proposed by Mr. Richards. He says :
"The law of suction seems to be that jigging is
greatly hindered by strong suction where the two
minerals are nearly of the same size, the quickest
and best work being then done with no suction ; but
when the two minerals differ much in size of particles,
the quartz being the larger, strong suction is not
only a great advantage, but may be necessary to get
any separation at all." Directly opposed to this, it
would seem that the practice adopted by Mr. Evans
would logically lead to a return to the continental
system of close sizing before jigging, since the larger
grains would yield more readily to the forces opera-
tive at such high speeds. The Review continues:
Another feature of the new system adopted at
Great Palls is an increase in the depth of the jig
bed, with the use of screens of larger mesh. That
this has been necessitated by the change to higher
speeds and shorter strokes indicates that Munroe's
law of hindered settling particles plays here a role
which, in some respects, must be different from that
which it performs with classified ores under the pre-
vailing American practice. There are features here
which are manifestly novel and require further
investigation. That greatly increased capac-
ity per unit of screen area is obtained by Mr.
Evans' system, without causing losses of valuable
mineral, is indubitable, and thus the value of the jig
is still further enhanced. In order to obtain the best
results with high piston speed, it is important to se-
cure a vertical motion with the piston held rigidly in
a horizontal position. This end has been secured in a
jig designed by Mr. Evans, having double piston rods
working through boxes fixed in the cover of the
piston compartment.
Mining in the Philippines.
At Washington, D. C, are received official Gov-
ernment reports showing that the mining bureau is
an interesting department in the administration of
Philippine affairs. The mining bureau is in charge of
C. H. Burritt, who went into the service as a private
soldier. Lieut. Burritt has translated and compiled
the Spanish mining laws which have been in force
since 1846, and has prepared a new system of laws
modeled upon those of the United States, but adapted
to the conditions existing in the archipelago, which
will be considered by the authorities and put in effect
when conditions warrant.
Concerning the mineral resources of the Philip-
pines, Lieut. Burritt says :
There are two belts of coal extending through the
whole archipelago on an angle of 60°, northeast and
southwest. The greatest deposits of coal are in the
islands of Cebu and Negros, the finest beds in the
small island of Bataan. This coal is all, so far as is
definitely known, of a Tertiary age and might be bet-
ter characterized as highly carbonized lignite. The
first discovery of coal was made in 1827, on the island
of Cebu, and since that time lignitic beds have been
found on the island in great quantities not 12 miles
from the capital. These mines have been worked, on
and off, at the different stages, but it was never real-
ized what a steady output was. Here the circum-
stances exist in that the seams and leads are badly
broken. Uling-Uling was and is now the principal
coal mine in Cebu. The coal of these islands is better
than Australian and Shanghai coal and equals that of
North Borneo.
Copper is next in importance. It is found in all
parts of the island, especially abundant in the
provinces of Lepanto, Benquet and Camarines.
The best known copper region lies around Mt.
Data, which is given out as being 2500 meters in
height. The ranges of which Data form one peak
trend due north to Cape Lacay and form the bound-
ary for all the provinces infringing on it. Data lies
in the province of Lepanto. In this range copper
ore has been found from time immemorial. Mean
assays show over 16% copper, mainly as tetrahedrite
and allied ore. The gangue is quartz. The rock in
the country is described as a large quartzite lens im-
bedded in a great mass of trachyte. Attempts have
been made to mine copper as well as coal, and with
the same results. This failure is not because of the
quantity or quality of copper, but because of a lack
of steady labor and proper means of transporta-
tion.
Gold is found in every part of the archipelago —
Luzon and Mindanao especially. Gold mining during
the Spanish regime was a failure, because of the tax
and unfair dealing with hired help. Placer mining
has never been seriously worked, although where gold
has been discovered it has always yielded well.
Of the other minerals of the islands, there are sil-
ver, lead, iron and quicksilver. The most important
deposit of argentiferous galena is at Tarrijas, on the
small island of Marinduque. A metric ton, or 1000
kilograms, contains 96 grams of silver, 6 grams of
gold and 565.5 kilograms of lead. Iron is found in
abundance in Luzon, Caraballo, Cebu, Panay and
other islands. Quicksilver is rumored to have been
found in the islands of Panay and Leytle, but no veri-
fication is placed on these rumors.
Lack of transportation facilities and of intelligent
labor are the chief obstacles to the development of
the mineral resources of the Philippines. In relation
to this, Lieut. Burritt says: "In all the island of
Luzon there is not a road that would transport prop-
erly a load of goods 200 miles. This fact has been,
and will be, the adversary of civilization, and until
good roads are built to intersect every part of the
islands civilization will be at a standstill, and the in-
surrection will go merrily on. Luzon needs roads to
open up its vast resources ; roads that will bear all
travel and still be good; not the roads of to-day,
which are an intermingled mass of mud after the first
rain. How can coal mines be operated without
roads ? How can copper and ore mines be operated
without roads ? That they can not be operated with
any success is proven by the many skeleton mines
that intersect the mountains of northern Luzon and
elsewhere and show the bitter experience of failure.
Roads and bridges of the highest standard are
needed. No roads, no peace ; no roads, no mines.
Labor is the obstacle that stands in the way of
success in mining in this archipelago. The native la-
bor is transient and can not be depended upon. They
will work until they have capital enough to lay off
three or four months, and love nor money could not
get them to do a stroke of work until they are broke.
That mines when once started should be kept going
is vital. Let a mine close for two months and its.
future is a failure. The importance of having labor
which can be depended upon is apparent. Unless the
Philippinos get down to business like they should,
they will be supplanted in the labor field by Chinese.
This is inevitable."
Removing Stumps With Dynamite.
Stumps can be removed by using dynamite, which
not only throws out the stump, but tears it in pieces
small enough to handle, the earth is cleaned off, and
the pieces may be cut up and used as firewood. In
placing the charge or charges under the stump the
operator must study the nature of the soil, size and
direction of the roots, and so place the charge that it
may present its explosive force against the center of
resistance. This can be done by boring under the
stump into the soil somewhat deeper than past the
center, so that the charge may be under the center
of the stump. In all cases put in enough dynamite
to do the work thoroughly. Where several holes are
loaded, the charges all coming close together under
the stump, one primer of a single cartridge will ex-
plode all the others. A hardwood tamping rod must
always be used to push the cartridges to the bottom
of the hole and to ram the hole full of dirt. It will
also be found necessary to use more dynamite with
pine stumps than with hardwood stumps, and in light
than in heavy soils. Prom two to three pounds of
dynamite are usually required to remove a stump.
The main object is to use rather more than too little
dynamite, and to concentrate the charge as nearly
as possible at the point of greatest resistance. The
tools required in stump blasting are a wood auger, a
dirt auger and a tamping rod. The augers should be
from i to 2| inches in diameter, with a shank about
5 feet long.
The best time to do the work is midsumme/, when
the ground is dry and hard. Place two sticks of
dynamite as close under the center of the stump as
possible and get the load close to or against the
wood, using a l|-inch auger with a shank 4 or 5 feet
long.
For placing the charge under the stumps, use two
2-inch augers, each equipped with a 5-foot shank, one
to bore into the dirt and the other to bore into the
stump root. The charge should be placed directly
under the middle of the stump, and it will take from
one-half to three cartridges, according to the stump.
The greatest care should be exercised in handling
the caps. The fuse ordinarily used will burn 1 foot
per minute and should not be cut less than 2 feet
long. That will enable the operator to get twenty
rods away. The 40% dynamite is safer than the
common black powder, as sparks will not ignite it.
When a stump is not entirely blown out, pieces of
others can be piled around it and it will burn out
readily.
Cement for Electric Wire Connections.
To make good electrical connections between the
adjoining ends of wires used as electrical conductors,
especially in electric lighting and power circuits, it
is customary to first twist or otherwise bind the ends
of the wires together in order to make a joint having
the required mechanical strength, and then apply
solder to this joint for the purpose of making a con-
tinuous metallic circuit of low resistance.
An improvement in this line is a metallic cement,
which may be applied to the joint by hand after the
wires are twisted or secured together without the
use of heat, and for all practical purposes takes the
place of solder. The cement consists of an amalgam,
with which is mixed a binding material, the mass hav-
ing about the consistency of putty. When put up in
stick form the cement will not harden, except at the
surface, where a slight crust is formed, and when the
mass is worked between the fingers it becomes soft
and plastic, so that it may readily be applied to the
wires. In making a joint the wires are twisted or
secured together, and the joint formed is coated with
cement.
The cement consists of the following ingredients in
the proportions specified : Zinc, four parts ; tin,
two parts ; copper, two parts ; cadmium, two parts ;
bismuth, four parts ; lead, two parts ; antimony, one
part ; mercury, eight parts. The solid metals are

granulated and melted together, after
which the mercury is added, the mass
being stirred at the same time. When
cool, the mass is pulverized in a mortar,
and a binding material, consisting of
liquid glucose and silicate of soda, in
sufficient quantity to bind the mass to-
gether and give it the consistency of
putty, is added to the mass. The ce-
ment thus formed will not harden when
in bulk, and may easily be worked be-
tween the fingers ; but when spread
out on a joint it not only adheres to the
latter, but hardens in from twelve to
twenty-four hours. The cement may
be applied to the wires without any
previous application of acid, and by
amalgamating with the conductors it
forms as perfect an electrical union as
could be formed by the application of
solder. The application of the cement
prevents oxidation of the wires. After
the joints are thus made they are cov-
ered with an insulating tape. — Ameri-

MINING SUMMARY.
ALASKA.
(Special Correspondence). — During the
past two months there have been several
new creeks discovered and some bench de-
velopments that are extremely rich. I
examined a bench claim near the head of
Anvil creek which paid about $1000 per
day to the rocker, and the one adjoining,
which was sold to C. D. Lane for $75,000,
before he got possession two men with one
rocker in thirty-five days took out $71,500;
but, in my opinion, they got the cream of
it, for at a recent visit I made it did not
look near so well. There are several
drawbacks to this country; the worst of
all is the pencil-and-hatchet-men, who
have staked the whole country from the
highest mountain to the lowest valley,
and never do any work; the next, the end-
less litigation; almost every claim of any
value in the country is to-day in the hands
of a receiver. Any one can put the best
claim in the country in the hands of a re-
ceiver whether he has ever seen the claim
or not; all he has to do is to put up a wil-
low stake as big as your finger and get
some irresponsible fellow to swear that he
had this stake last year, or that the
other fellow's location was not properly
made.
We are just now in the midst of the
greatest storm of the season. The damage
to property on lower Main street and
along the beach will reach close on to
$1,000,000 in the last forty-eight hours,
and many hundreds are left homeless and
penniless. The sight in the surf is grand,
yet frightful, to see a great mass of lum-
ber and property of every description
hurled round and round at the mouth of
Snake river and dashed back and forth by
the surf until it is ground into kindling
wood. Miner.

off their giants working there and are ex-
tending their flume 1 mile farther down
the Salmon river to work a rich bunch of
gravel at that point. The company's
flume is already 5 miles long and the ex-
tension will make it one of the longest
flumes in the State. There are other un-
developed gravel claims along the Salmon
river yet and capital would be recom-
pensed by an investigation.

The "inverted siphon" of the La
Grange Hydraulic G. M. Co., forming a
part of the main water system, conveys
the water of Stuart's Fork and Rush
creek to its mines on Oregon Gulch moun-
tain and Morris hill. The pipe is 30 inches
in diameter, made of steel, and was tarred
and tested before being put in place. It
is anchored at all angles and buried for a
great part of its length in a trench 3 feet
in depth and 3 feet in width. There are
eight 3-inch valves on the inlet side and
five manholes at points about 1000 feet
apart. Expansion joints are provided at
each end of the pipe just below the inlet
and outlet pieces. The inlet piece is bell-
shaped, 4 inches diameter at the upper
end and tapers gradually to 30 inches. It
receives the water from the bottom of the
head box and is curved at the smaller end
to come into line with the pipe on the hill-
side. The outlet piece is in the shape of a
bonnet, 4 feet in diameter at the upper
end, and discharges the water into the
vertical end of the outlet box. At the
lowest point of the "syphon" the pipe
has a 4-inch gate valve, which serves as a
blow-off cock when necessary to at any
time empty the pipe, opened and closed
by bevel gearing. The pipe crosses Stu-
art's Fork on a wooden truss bridge 12
feet wide, 138 feet long. The main water
system consists of 23.85 miles of flume and
ditch, three inverted "syphons," aggre-
gating 8754 feet in length, and eight tun-
nels, aggregating 11,134 feet, making a
total length of 27.61 miles of mining ditch.

Among other improvements in mining,
milling and smelter practice the Leadville
Carbonate Chronicle notes an expenditure
of $100,000 in the Arkansas valley smelter
by Manager Weddle designed to accom-
plish a saving. There was a waste in slag
and a loss in smelting caused by the fumes
and gases from the blast furnaces, which
all contain values in the shape of gold,
silver and lead, in a measure saved by the
use of large brick chambers, through
which the smoke and gases pass, the
heavier particles settling to the floor.
With the best flue chambers designed,
however, only a portion of the values have
been saved ; the system in operation Nov.
1st at the Arkansas valley plant is in-
tended to save practically everything
worth saving in the smoke from the
furnaces. There are two sections in the
system of flue chambers. One extends be-
yond the plant for about 1000 feet, arched
shape, a cross section of which measures
256 square feet ; material used is iron and
cement, frame work of channel iron with
metal lath wired to the beams, covered
with a coating of cement, inside and out,
an air space of about 2 inches being left
between the two coats, air tight and im-
pervious to moisture. The interior of this
chamber contains a few feet from the
bottom a V-shaped trough, where the
heavier particles settle. Cars will be run
below this trough and the flue dust col-
lected every day. The second section
consists of a different shaped chamber, but
of the same material, iron and cement,
known as the beehive. The system con-
sists of three parallel chambers, nearly
1000 feet each in length, but each one con-
nected. The arched openings, howevor,
can be closed by iron dampers, permitting
one parallel line to be entered and cleaned
out, while the smoke winds its way
through the other two, until it enters the
stack. As the heavier particles in the
smoke will settle in section No. 1, the
deposition in the second section will be
slower ; it will not be necessary to make a
cleanup more than three times a yoar. To
assist in supplying a draught the same
stylo of chambers are being constructed
from the Ropp and hand roasters. The
circular stack is 185 foet high, inside di-
ameter 18 feet.

JUAB COUNTY.
(Special Correspondence). — The Eureka
Hill combination mill is operating on 175
to 200 tons of very hard ore per day.
The mill contains 100 stamps, 1000
pounds each, 100 drops per minute;
fifty Frue vanners, thirty-two amalga-
mating pans, sixteen settlers, a number
of clean-up pans, retort and smelting
furnaces. At present sixty stamps arc
doing the work. In former years plates
were in use below the batteries, but that
was at a time when the gold in the ore
was a more important factor than now.
The ores carry oxides, sulphides and
chlorides ; the values, named in the order
of their importance, are silver, lead, gold
and copper. The silver which is found
with the galena and lead carbonates is
saved in the concentrates ; that in chloride
form being saved in the amalgamating
pans. In the pans a small percentage of
gold is obtained, but the most of it is saved
in the concentrates.
The ore passes through Gates' crushers
before going to the stamps. The product
of each battery of five stamps passes to
three vanners set in tandem — each vanner
getting a third. Formerly sizers were
used to divide the material, 'but they were
discarded, first, because it is claimed they
did not do their work perfectly on these
ores ; and second, because it seemed a
better saving was made to permit the fine
and coarse material to pass over the belts
together. Hence, the product is the same
from all the vanners. The bulk of the
ores carry a high percentage of silica,
which is pretty thoroughly eliminated
from the concentrates by the vanners,
though some of the fine carbonates are
lost in the siliceous tailings. Now these
vanner tailings are collected in a series of
settling boxes — the water and slimes over-
flowing from one into another, the first
box catching the heaviest and coarsest
sand and the next the finer and more
slimy substance, and so on. The water,
finally, is pumped up to the battery floor
for use again on the stamps. When the
boxes are full the material therein is
dropped down through traps to the sand
floor, where the different grades are mixed
to make it quite uniform in consistency
before it is thrown into the pans. As is
usually known the pans are provided with
agitators, by which the pulp is kept
stirred to a ropy state during the process
of amalgamation. The water in the pans
is kept heated by live steam from the
boilers.
The mill is located on the side of the
mountain, some 300 feet higher than the
ore landing of the mine shaft. The ore is
carried from the mine to the crushing
floor of the mill by a tramcar line ; a sec-
ond tram line carries the concentrates
from the vanner floor to the railroad
track ; a third train conveys coal from the
railroad to the mill boiler room. The
engine room contains a 500 H. P. engine.
Eureka, Sept. 27. Wascott.
(Special Correspondence). — The Star
Con. mine, which has been greatly im-
proved within the last few months, is
shipping one car per day of gold-bearing
ore, which runs in value from $1200 to
$1500 per car. The ore is largely oxidized,
and it is claimed much of the gold is in a
sylvanite. Present shipments come from
the second, third and fourth levels. Re-
cently a new ore body was opened on the
fourth level in a drift some distance from
the shaft. Besides the shipping ore, a
large tonnage of milling ore is accumu-
lating at the mine. Besides the gold val-
ues, the ore carries silver, which averages
about ten ounces per ton. The work is in
charge of Supt. C. F. Packard.
The Boss Tweed, located a short dis-
tance from the Star, but farther up the
hill, is being worked under lease to Wm.
Gundry & Son, who are shipping about
one car per month of high-grade copper
ore, which is found in sulphide and oxi-
dized form, mixed with red, vitreous and
silicate copper, with apparently some
green copper carbonates, all making a dis-
play of variegated colors.
The South Swansea has built a new
shaft house, put in new hoisting machin-
ery and sunk a 650-foot shaft about 100
feet from the old shaft. The new shaft,
through which all the ore will be handled
in the future, is 30 feet west of the vein at
the 650 station. It is expected that pres-
ent shipments will be increased. The ores
here are silver and lead.
The Carissaand Spy, a group belonging
to a Colorado company, at the head of
which is Eben Smith of Denver, are being
rapidly put in position to increase their
output. The Carissa now ships 300 tons
per month of gold, silver and copper ore
from the 100-foot level. The ore carries
about three ounces gold to the ton. The
copper occurs as gray copper and copper
carbonates. The gold is in quartz, spar
and baryte crystals. The Spy, one of the
old properties of the district, is being put
in good condition, as regards equipment
and buildings. The shaft is 700 feet deep.
The ore now being taken out carries cop-
per in an oxidized and carbonate form,
with also some native copper and iron; the
whole, it is believed, runs 20% copper.
Present shipments amount to about sev-
enty-five tons per month. About twenty-

Silver City, Sept. 30.
(Special Correspondence).— Within the
past year a steel structure has been erected
over the Grand Central, making a shaft
house, blacksmith shop, engine room and
boiler room, all under one roof, but suit-
ably divided off. Over the 1100-foot shaft
is a 50-foot steel gallows frame, extending
to the apex of the main steel building.
The hoisting equipment consists of an
engine with||18-inch cylinder and 48-inch
stroke ; a double reel for 4J-inch flat
cable. The hoist is good for 2000 feet
depth, with a maximum speed of 2000
feet per minute. The air compressor is
a fine! piece of machinery, having piston
inlet air cylinder, 18£x32 inches; with
16x32 steam cylinder. It is the right hand
half of an eighteen-drill duplex and conse-
quently has nine-drill capacity. The
power comes from two 80 H. P. return
tubular boilers.
The electric signal system works per-
fectly. It produces flashlights for station
signals and has closers on cage by which
bells may be given the engineer while cage
is in motion. A 6-inch, riveted, spiral,
sheet-iron pipe is in use for conveying
compressed air from compressor to the
1100-foot level; in the drifts 3-inch iron
pipe is used. An air pressure of ninety
pounds per square inch is used.
The Grand Central vein has been opened
vertically from the fourth to the eleventh
levels and in length 1000 feet. The ore
occurs in the blue dolomite line ; the vein,
which generally is vertical, ranges in
width from 5 feet to 125 feet. The work-
ings are timbered up in square sets. The
ore, which at present comes from drifts
about 500 feet east of the shaft, consists
of sulphides, oxides and chlorides, carry-
ing gold, silver, copper and lead. Most of
the gold is found in the oxidized ore ; the
silver in the sulphides and chlorides. The
dry ore averages thirty-five ounces silver,
$15 to $20 gold and 10% copper ; separate
from that are the sulphide ores which run
45% to 55% lead, sixty to seventy ounces
silver and $5 to $7 gold to the ton. Ship-
ments now run about sixty tons per day.
On the premises is a large dump which is
being preserved as milling ore. The de-
velopment of the mine has been under the
direction of Supt. Pat Donnelly.
The Emerald, in charge of M. L.
Oglesby, did 1500 feet of work the past
year and erected a new shaft house and
gallows frame. On the 500-foot level some
ore was found, though no shipments have
been made as yet.
The Mammoth mine is producing about
3400 tons per month, part of which is
treated at the Mammoth mill at Robin-
son. The ores are gold, silver, lead and
copper. The mill operates sixty stamps,
thirty-six vanners, twenty-eight amalga-
mating pans and fourteen settlers, the
method of saving being similar to that of
the Eureka Hill mill.
The Black Jack, belonging to Knight &
Evans, has been well equipped with hoist-
ing machinery ; a 400-foot, double-com-
partment shaft has been sunk, from which
prospecting levels are being run for ore.
Mammoth, Sept. 29.
(Special Correspondence). — The Eagle
& Blue Bell group, in charge of J. C.
Chrystal, is located on the Eureka side of
the range and has been well equipped
within the past year. This was formerly
a silver producer in the main, but of late
the principal values are gold. Shipments
have been made with more or less regu-
larity during the past two years. Present
shipments run one or two cars a month,
the returns ranging from three to seven
ounces gold, with a few ounces silver.
Much of the latter is in the form of a
chloride. The mine contains a great deal
of ore that would be adapted to concen-
tration and the erection of a mill may be
considered later on.
The Centennial-Eureka maiutains the
shipment of its regular tonnage. Within
the past year considerable improvement
in equipment has been made, including a
tramway line over which the ore is car-
ried from the mine to the ore bins at the
railroad. The electric signals, which have
been in use in the shaft for two years, ap-
pear to operate very satisfactorily. Not
only can signals be given from station to
station, but those on the cage can signal
the engineer to stop or start at any point
in the shaft.
The Bullion-Beck concentrating mill,
which has been closed down for some
time, was designed to run on the low-
grade lead ores. As this class of ore
has accumulated in the past the mill has
always handled it, and doubtless will do
so in the future. The high-grade product
is always shipped to the smelters. A
strike of considerable importance is re-
ported to have been made in the Muldoon
tunnel, on Bullion-Beck property, in the
vicinity of the Centennial-Eureka.
The Apex, whose earlier development
was through the Uncle Sam tunnel, is
now sinking a shaft from an upper 800-
foot tunnel to reach its lower workings,
450 feet below the latter tunnel. The
Apex ore body pitches eastward 65° from
the horizontal and carries a fair valuation.
L. C. Doty has charge of the Apex.
The Yankee Consolidated, near the May
Day, recently opened a new ore body,
from which a three-car shipment was
made, the values therein being a heavy
lead sulphide, carrying gold and silver.
The Uncle Sam, belonging to Knight &
Sons, has a record of having produced
$600,000 since it was opened, its ores being
high-grade lead. Some of its shipments
have run as high as 70% lead, and it is
stated that no shipments have run below
50%. The Humbug, in the same locality
and under the same management, though
not at present a large shipper, is said to
have high-grade ore and will be in posi-
tion to ship at almost any time.
The Victoria recently put in a hoist and
sunk a shaft 550 feet, from which consid-
erable amount of drifting was done. This
belongs to the Grand Central people.
Most of the new work on the lime belt
of the Tintic range, within the last two
years, has been done by local people. This
comprises that section running from the
north end of the spur at the Uncle Sam
south to Mammoth.
Eureka, Sept. 28.
SALT LAKE COUNTY.
The Liberal and Butler No. 2 at Bing-
ham have an option by C. C. Hayden of
Colorado and J. Hudgens of Arizona, they
binding themselves to pay for it $50,000
before the expiration of eighteen months.
The Bulletin hears that development
operations are to be resumed at the Red
Wing group, under the direction of H. T.
Sappington.
Improvement is noted at the Last
Chance mill. A sample of old tailings
assayed 2% lead, 2.5 ounces silver and
$2.40 gold. Present tailings show a trace
of lead, 1 ounce silver and 70 cents gold.
WASHINGTON.
J. M. Dennett says that he has "pene-
trated into the Cascade range 60 miles
from the railroad, and after two days of
prospecting located veins showing 19 feet
of anthracite coal." He estimates the
quantity of coal in sight at 25,000,000 tons,
but may be unduly optimistic.
FERRY COUNTY.
Fifteen miles south of Republic the Ignas
M. & M. Co. is developing the Ignas
mines under the superintendence of E. W.
Lafrances. In a belt of schist and black
shale is a vein of 8 feet of ore, carrying
100 ounces in silver.
Supt. D. C. Jackling expects the new
Republic mill will be ready to operate next
week.
KITTITAS COUNTY.
At Liberty, L. Alstrom last week in
the placers of the Swauk found a nugget
which weighs 24J ounces and is valued at
$350.
OKANOGAN COUNTY.
The Okanogan Free Gold Mines, Ltd.,
near Oroville, is in the hands of the sheriff,
who has stopped all work on the claims.
Supt. Finley estimates that by sinking a
shaft 150 feet deeper than the lower work-
ings and crosscutting 100 feet the vein
could be reached at a place where the ore
body would be undisturbed, and figures
the cost of this work at $4600.
SPOKANE COUNTY.
The mining department of the Spokane
Industrial Exposition, which opened in
Spokane on the 2d inst., has a good dis-
play of minerals. Among the locations
which have prominent exhibits this year
are Slocan, Nelson, Ymir, Ainsworth,
Rossland, Boundary, East Kootenay, B.
C, the Coeur d'Alenes, central Idaho,
Libby, Montana, Okanogan and eastern
Oregon.

At Sandon the Ivanhoe mill, belonging
to the Minnesota Silver Co., has started
up. The concentrator has a capacity of
200 tons a day. P. Hickey is Supt.
One million shares of the Rossland Giant
are reported bonded to San Francisco
men for $100,000. The bond goes into ef-
fect Oct. 1, and is for two years. In that
time the bondholders, according to the
agreement, must sink a new working
shaft 700 feet, do 1000 feet of tunneling
and 1000 feet of diamond drilling. The old
owners are to receive 55% of the net pro-
ceeds from ore shipped during the two
years; the other 45% will be held in
escrow as a protection to them should
bonders break the contract.
At Nanaimo, September 30, at a meet-
ing of the Miners' Union the question of a
10% increase was reopened and it was de-
cided to ask for the raise.
"Miners (200) wanted to go to British
Columbia ; passage advanced ; wages 12
shillings per eight hours' day. Apply for
further particulars to E. 2780, Mail office."
The above advertisement appears in the

gow Mail.
Nelson reports that a new straight-line
roasting furnace is to be installed at the
Hall mines smelter. The hearth is 12 feet
wide and 120 feet long.
The Jaune de Lamare syndicate is oper-
ating fifteen hydraulic leases, comprising
about 1000 acres of auriferous gravel, at
Boulder Creek, Atlin. Twenty men are
at work with two monitors.
Kamloops reports a strike of cinnabar
at the mines near Savona, where work
was recently resumed.
In the Lenora copper mine on Mt.
Sicker, Vancouver Island, its shipments
average 1200 tons a month. The ore runs
$2. 50 in gold, $2.50 in silver and 10% wet
assay of copper to the ton.
At Greenwood the first ore shipments
to the smelter took place on the 26th.
The smelter will not be in operation until
December.
The Granby smelter will ship about 150
tons matte to New York.
At Nelson the recent payment of a 5%
dividend on the capital stock of the Atha-
basca is to be repeated quarterly.
About 1800 tons of concentrates of lead
from the St. Eugene mine at Moyie have
been shipped to a copper smelter at Anto-
fagasta, Chile. The British Columbia
product is used for fluxing purposes.
There is an unlimited market in Chile for
concentrates of lead.
BRITISH GUIANA.
U. S. Consul Moulton to Demarara,
British Guiana, says the rush to the gold
fields of Guiana and Venezuela, which
was expected to follow the settlement of
the Venezuela boundary dispute, failed
to materialize. The new boundary fixed
by the arbitration court is quietly ac-
cepted by the people of British Guiana
and Venezuela. Gold mining is being
prosecuted in the British Guiana gold
fields, and a few Americans are there try-
ing to make their fortunes. The yield of
those gold fields is about $2,000,000 a
year. All the gold obtained is secured by
placer mining. Mining in British Guiana
is attended by the greatest difficulties and
hardships, and there is danger to life.
The gold fields are all at some distance in
the interior. To reach them the miners
have to travel through swamp lands and
dense brush, which are infested by alli-
gators, enormous reptiles and wild beasts.
Everything the miners carry along has to
be packed by men. British Guiana is no
place for American miners.
LOWER CALIFORNIA.
Ensenada, capital upper district of
Lower California, reports that Benton,
Ramsdale & Stevens have deposited with
the Secretary of Mines for the northern
district of Lower California, $75,000 in
silver, and filed denouncements for nearly
4000 claims to copper mines in the interest
of Montana parties. The denunciations
begin as far south as San Fernando, where
the greatest number of claims are, and
run through the known copper country as
far north as San Ysidro. Each claim is
40 meters square. There is no limit to
the number that one may file upon, pro-
vided he pays the location fees.
SOUTH AFRICA.
All points of view are interesting. R.
Redmon, from Johannesburg, who says
he has been connected with newspapers in
South Africa for seven years, says that
the Transvaal of the future will not com-
pare with the republic under Boer rule.
He thinks it will be twelve months before
the gold mines of the Rand can be cleared
of water and the machinery put in work-
ing order ; the chief difficulty or menace
to the welfare of the ordinary working
individual will be the consolidation of
mining interests, the amalgamation of the
various gold trusts into one gigantic cor-
poration that will shut out the miner and
ordinary workingman from the chance
they might have had. This fact is evi-
dent, the consolidation is sure. " One has
only to turn to Kimberley, the diamond
district, and observe the limited amount
of labor required to work that great dia-
mond country. I recall the time when
Kimberley employed thousands of work-
ingman of all classes, when every aurifer-
ous field was thrown open to the public,
when every individual worked on a basis
of equality as regards the natural wealth
of the ground, when the working miner
had the same opportunity of a rich find as
the capitalist who might own the next
claim. Everything prospered. Rhodes
and his party were able to amalgamate
the various interests and buy out the
smaller people. Competition was useless.
The great De Beers diamond trust was
formed, which to-day rules the diamond
market of the world. Very naturally the
output of diamonds was curtailed in order
to keep up market prices. Thousands of
workmen were left to starve, and the once
prosperous colony of Griqualand West be-
came a slow mining village, with only the
De Beers company to keep it afloat. Later
on these self same workmen, miners,
chiefly Americans, found employment on
the Johannesburg gold fields, and were
satisfied to work under the government of
the Transvaal. All mining claims were
distributed fairly to taxpaying citizens,
and the Uitlander had the same oppor-
tunity as the Boer. In fact, the ordinary
Boer was satisfied to work on his farm and
leave the gold to the more progressive
European or American. It needs very
little prophetic insight to predict the
South Africa of the future. The same
conditions must prevail on the Witwat-
ersrand as were put in force in Kimber-
ley, as the controlling interests are held
by the same men. Cecil Rhodes is the
head of the great diamond trust, and is
the largest shareholder in Transvaal
mining companies. With the exception
of a few American, German and French
companies, the whole of the Transvaal is
in the hands of the Rhodes interest.
Under the new rule, therefore, the only
issue will be the speedy consolidation of
the mining interests, the closing of the
smaller mines and the regulation of the
output of gold to suit the London market.
Instead of a city of 120,000 inhabitants,
Johannesburg will take a turn after the
manner of Kimberley, and become merely
a small mining town, controlled by the
Rhodes Consolidated Gold Mining trust.
Interested publications prophesy a coming
'boom ' in African stocks and shares, but
the boom can be safely put down as im-
aginary. It will not come. On the con-
trary, many of the smaller companies will
go into liquidation and the interests will
be bought up by the larger trusts. Miners
and tradesmen will not find employment
in the Transvaal under the new rule. The
volunteers now fighting will, of course, be
given the first chance, and very few men
will be required to work the consolidated
mines."

Squire V. Mooney, manager The
John A. Roebling's Sons' Company, 25-27
Fremont street, San Francisco, has notifi-
cation that that company, with head-
quarters and manufactory at Trenton,
New Jersey, has received for its exhibit
at the Paris Exposition two grand prizes
and two gold medals, the highest honors
within the gift of the Exposition authori-
ties. The Roebling display at the Expo-
sition consisted of two exhibits, one the
products of the company's electrical de-
partment, the principal feature a full size
model of a section of underground trolley
track, illustrating the communications
with the conductive bars and the lead-
encased cables which transmit the current
to the cars, the other exhibit in the de-
partment of metallurgy, giving compre-
hensive view of all the products of the
Roebling works, with the exception of the
electrical conductors. Part of that ex-
hibit contains samples of every variety of
steel and copper wire, from the largest
sizes made to wire with a diameter of
io'ua of an inch. This latter is so fine that
it is impossible to detect it between the
fingers. It is half as thick as the finest
human hair, and a mile of it weighs about
a quarter of an ounce. It is drawn through
diamond dies, and is a good example of
the skill displayed by the workmen in
the process of manufacture. The Roeb-
lings have exhibited at all the prominent
expositions for a number of years and pos-
sess many awards conferred, including
gold and other medals. At the Centen-
nial, at the World's Fair in Chicago and
at the Philadelphia Export Exposition the
excellence of its manufactures was acknowl-
edged. The Roebling Company in the last
two years has built a large wire mill, and
has in its employ about 3000 operatives.

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co.'s Scien-
tific Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Automatic Flusher. — No. 658,139.
Ira P. Clarke, Alameda, Cal. The object
of this invention is to provide an auto-
matic apparatus for the flushing of sewers
and the like at frequent intervals. It con-
sists of a chamber or receptacle having an
opening connecting with the sewer, and a
valve by which the opening is closed. A
float is suspended from one end of a lever
fulcrumed above the valve, and a weighted
traveler is movable to and from the ful-
crum point on the opposite side of the
lever. A chain connects the traveler
with the valve so that when the float has
risen to a certain point the traveler will be
disengaged, and will move quickly to the
outer end of the lever, thus suddenly
opening the valve to allow the escape of
the water. As the water discharges the
float will sink, and will again tilt the lever
into such position that when the tank is
approximately empty the traveler will
rapidly return toward the center of the
support of the level-, and slackening the
chain will allow the valve to close sud-
denly upon its seat. The flow of water
being continuous will cause this operation
to continue automatically and indefinitely.
Manufacture of Flat Wire Ca-
bles.—No. 658,118. Sept. 18, 1900. E.I.
Parsons, San Francisco, Cal., assignor to
the American Steel & Wire Co. of Chi-
cago, 111. This invention relates to an
apparatus which is used in the manu-
facture of cables, such as are made by lay-
ing a series of ropes side by side, and
stitching them through to form a flat
cable. The difficulty in manufacturing
this class of cables arises from the unequal
tension upon the transverse sewing wires
caused by different power applied in pull-
ing the wires through. In this invention
the pull upon the stitching wires is made
approximately the same by means of a bar
having a hook upon one end, through
which the pull is exerted. There is a
shankor stem upon which the hook bar is
slidably guided, said shank having a han-
dle and a yielding spring and latch
mechanism through which connection is
made between the handle and the shank.
There is a device by which the latch is
disengaged when a given tension has been
reached so that the pull upon the stitch-
ing wire will always have the same ten-
sion, and if this is exhausted the latch dis-
engages and relieves the pull.
Deflector for Hydraulic Nozzle.
—No. 658,516. Sept. 25, 1900. J. W.
Smith, Weaverville, Cal. The object of
this invention is to provide a means for
changing the direction of hydraulic nozzles
through which water is discharged under
a high rate or groat pressure. It consists [
of a supplemctal pipe, and means for sup-
porting it axially in line beyond the main
nozzle, with a lever or means by which it
can be turned to either side, or up and
down, so that the stream of water issuing I
from the nozzle will impinge upon this ex-
tension, and will, by thus acting upon
it, turn the main nozzle to the opposite
direction by the reactionary force of the
water upon supplemental nozzle, while the ,
latter is held in this position. When the
supplemental nozzle is released it will of
itself return to a position in line with the
main nozzle and will not interfere with the
stream which is discharged therefrom.
Bed Bottom.— No. 658,053. Sept. 25, I
1900. G. H. McBride, San Francisco, Cal.,
assignor of {fa to D. H. Bibb, of same
place. This invention consists of a rect-
angular bed bottom frame with spirally
twisted elastic cables having their ends
fixed to the opposite ends of the frame and
intermediate between the ends, the cables
are interlaced in such a way that they
mutually support each other, and by be-
ing immovably interlocked any pressure
which may be brought upon one side or
the other is transmitted so that all of the
cables sustain a portion thereof. The
usual top mattresses are placed upon this
structure to complete the bed.

SILVER— Per oz., Troy: London, 29 Id
(standard ounce, 925 fine); New York, bar
silver, 64c (1000 line) ; San Francisco,
63|e; Mexican dollars, 51|c.
There is a noticeable rise in silver, edi-
torially discussed on page 398. Regarding
the Government purchases of silver, it is
to be noted that the Government at pres-
ent purchases only such silver as is con-
tained in gold deposits from the Klondike
and other gold-producing sections. Un-
der the existing statute all silver in gold
deposits is paid for at the market price.
The advance is a good thing for Western
silver-lead producers. The Bulletin re-
ports specie shipments from San Fran-
cisco during the month of September as
follows :

lb., 2.50c in small quantities.
STEEL.— Bessemer billets, Pittsburg,
$17.50; sheet bars, $22; San Francisco,
bar, 7c to 12c per lb.
The steel rail pool has fixed the price of
steel rails for the coming year at $26 per
ton — $9 per ton cheaper than last year and
$1 higher than it was expected the rate
would be. On 80-pound rails that is a
reduction of $1131.40 to the mile in the
cost of rails.
The rail makers, in reducing steel rails
from $35 to $26, a reduction of about 25%,
figure a market for, in round figures,
2,000,000 tons of rails, or the bulk of the
rails that will be needed for the require-
ments of 1901. There is considerable
profit at $26.
The price for Bessemer pig is $14 and of
slabs $17.50. A slab is a steel rail in the
form of a chunk of steel. For nominal
cost it is rolled out long into steel rail.
For this $3 is the charge. At, this cost
steel rail is worth $20.50 per ton.

CROWN GOLD MILLING CO
Manufacturers of the "CROWN" CONCENTRATOR and CROWN
ORE SIZER. A dry process of sizing and concentrating ore, sand or
gravel. Designed to accord fully with the laws of specific gravity,
and especially adapted to refractory ore or localities where there is
no water.
The chief claims for the Crown Concentrator are that it occupies
less floor space and has nearly four times the capacity of any wet
concentrator; that it will concentrate ores containing base and refrac-
tory metals that ordinarily slime and carry off values; that it effects
a saving of values far above the ordinary methods of concentration.
We have, now in operation, a complete plant
for crushing, sizing and concentrating ores by the
Crown Dry Milling Process.
Mine owners desiring tests made can forward
us, freight prepaid, not less than 1000 lbs. nor
more than 4000 lbs. of sample, for which a
charge of $20 will be made. (This amount in-
cludes assaying, etc.)
Ores for which this process is adapted and of
which consignments are solicited are any con-
centratable ores, pulps, tailings, or sands, carry-
ing sufficient values, whether they have hereto-
fore been profitably concentrated or not.

THE GRI
THREE ROLLER
7VYI
The Gi-ifllu Threo Roller Oro Mill Is a simp.y constructed Mill, suitable for working all kinds of ores that
require uniformly fine crushing by the wet process. This Mill is a modification of the well-known Chilian
Mill, but the rollers run upon a crushing ring or die, which is inclined inwardly at an angle of about 30 degrees,
the rollers themselves also being inclined to the central shaft of the Mill, thus utilizing the contrifugal force,
as well as the weight of the rollers themselves as a crushing agont. The Griffin Three Roller Ore Mill is there-
fore a Mill of great strength, and has few wearing parts. We construct those Mills with extreme care, using
only the best of raw materials, which are most carefully worked by men who are specialists as mill builders.
We sell the Griffin Ore Mill on its determined merits, and wi'l gladly supply full information regarding it to
any one.

SPADONE'S CONCENTRATOR BELTS.
PATENTED.
This illustration shows the edge flanging out-
wardly as it passes over the pulley. This re-
lieves the strain from the top and bottom of the
edge by directing the strain automatically to
the inside face surface of the edges. Hereto-
fore all belts have been so constructed tbat
when they pass over the pulleys or rolls, a di-
rect strain comes upon the top or at the base of
of the edges, causing the edges to break away
from the body of the belts in a very short time.
We avoid this Mechanical Defect by our Spadone
Curved Edge. Belts made to fit any machine —
4, 5 and 6 feet wide. Prices and samples on ap-
plication,

How This Paper Grows.
— »
The accompanying illustration graphically por-
trays the growth of this paper. In the picture is
seen on the left the volume for the last half of 1894,
which contained 41f> pages. In the middle is the
volume for the last half of 1896, which consisted of
540 pages. On the right is portrayed the volume of
the paper for the last half of 1899, which contained
772 pages. The present volume, for the last half of
1900, will be still larger. This shows the growth in
the size of the paper. There is even greater propor-
tionate growth in the number of its readers. It
would take considerable space to show this ; but that
fact is well understood by the advertisers. Of
course, the better the paper the more readers, and
the more readers the more advertisers. The circu-
lation of this paper is among men who not only can
afford to pay for it, but who can also afford to buy
what they see advertised therein, and that is the
kind of circulation that pleases readers and adver-
tisers, as it insures a publication of value to all. In
its latest noted reference to this paper the American
Newspaper Directory, through Printer's Ink, said :
Among the engineering and mining papers in Cali-
fornia, none has credit for so large a regular issue as
is accorded to the Mining and Scientific Press,
published weekly at San Francisco. In fact, it fully
equals five times the combined issue accredited to all
the others. In all the States of the Par West and
the Pacific Slope, consisting of California, Oregon,
Washington, Idaho, Montana, Wyoming, Colorado,
New Mexico, Arizona and Utah, the largest circula-
tion credited to any publication devoted to engineer-
ing and mining is accorded to the Minino and Scien-
tific Press.
The above, from the highest authority on the sub-
ject, was, of course, pleasant to know. That was
said some considerable time ago. Doubtless were
similar reference made now the comparison would be
even more flattering to this paper.
ing these fissures in the hottest parts is gelatinous,
in others spongy and in others hard, or in layers of
agate, chalcedony or sugar quartz. Everywhere
there is the same distinct ribbon or banded structure,
resulting from successive layers of quartz being laid
on the sides of the fissure by watery solutions. The
quartz in these fissures contains sulphides of iron,
copper, cinnabar and even free gold. The metallic
contents, as in old fissure veins, are in much less pro-
portion than the quartz veinstone."
These statements have given rise to considerable
inquiry and discussion. The brief facts were stated.
Some interesting theories as to the formation of lode
matter are formulated.
The solution of such questions is an interesting
study. Many theories as regards their formation
have been advanced since geology has been recog-
nized as a science. Werner's theory, the descension
theory, explains the formation of lode matter through
infiltration of water holding the metals in solutions
Formation of Lode Matter.
In the issue of the 22nd ult. it was stated on page
339 that "sulphide of mercury may be found at Sulphur
Bank, Colusa Co., Cal., where also may be seen in de-
composed volcanic rocks fissures from which issue
steam and hot alkaline water, the sulphur springs de-
positing siliceous sinter which contains cinnabar and
sometimes gold, as do Steamboat Springs, Nevada,
where can be seen ore deposits in process of forma-
tion." In the issue of Feb. 17, 1900, it was stated on
page 175: " The origin of ore deposits and mode of
deposition can be conveniently observed at Steamboat
Springs, Nevada, where clouds of steam issue from
many vents, over a bare rocky space half a mile long,
in a narrow valley lined by volcanic ridges on each
side. The vents are separated, but occur in parallel
lines, showing that they are connected by fissures,
filled with opaline quartz. The fissures traverse a
continuous crust of deposited quartz, some open, some
partly filled with quartz, water issuing from a nar-
row middle crevice. Some are wholly filled with
quartz and have become true quartz-fissure veins.
Some of these larger fissures are half a mile long, a
foot wide, open and parallel, about 25 feet apart, and,
descending downward to the bottom of the quartz
crust 30 feet, can be followed no farther because they
have deposited quartz in such abundance as to cover
up their original vents in the underlying rock.
Water does not issue from all the fissures, but can be
seen and heard 8 or 10 feet below in violent agitation
rom steam and carbonic acid gas. The quartz fill-

from higher situated rocks. It offers, however, no
explanation as to where the metallic content of the
water is derived from. The descension theory may
still be recognized in cases where is found an ore de-
posit in caverns, and where the presence of the met-
als above can be proved with certainty.
Two are often discussed : the ascension and lateral-
secretion theory. The ascension theory supposes, in
all cases, the lode matter to be brought from a
greater depth into the fissures, either by ascending
mineral springs or by sublimation. The material
found in the lode must be therefore different from
that found in the country rock, and must only occur
there in the form of impregnation on the sides of the
lodes.
There are many ascending acidic mineral springs
which contain, besides sulphates, organic matter,
and deposit no sulphides in the fissures. The forma-
tion of sulphides could only take place by gradual re-
duction of the sulphate with a larger amount of or-
ganic matter than is at present in the spring. Such
springs never have been, and never will be, the me-
dium of the lode formation. Many springs, acidic
and thermic, issue from fissures in a lode, and are
therefore taken as the means by which the lode has
been formed. This, however, is not correct, for if it
were the case one would find newly formed ore on the
walls of these fissures.
Ascending mineral springs, coming from lodes, no
matter of what temperature, should not be regarded
as the means of bringing the ore into the fissure.
They use the lodes, just as any other fissure, simply
as the shortest way to the surface, where they de-
posit the substances, leached out of the rocks, as
ochre.
There is, however, another class of mineral springs,
and especially thermal springs, of high tem-
perature, which precipitate, besides silver and
sulphur, smaller argentiferous or iron pyrites,
and even native gold ; these springs are found
in California and Nevada, and two of them were re-
ferred to as above. They are of interest to the prac-
tical man, as in some of them one may observe the
formation of mineral veins at the present time. The
cinnabar deposits of California are of different char-
acter, and should not be discussed as a whole, but in
groups. For instance, in the Rattlesnake mine, So-
noma Co., Cal., is found mercury, together with liquid
petroleum, similar to the deposits of Idria, as an im-
pregnation on clay. In other places, again, it occurs
as an impregnation on sandstone. More frequently
cinnabar, together with selenium mercury, forms de-
posits of the stock work or lode form, which, as a
rule, are not of large dimensions, but which some-
times, as in Lake Co., Cal., are of some length and
thickness. All important deposits are ordinarily
accompanied by quartz, sometimes also by opal and
brannite, as in the Redington, Cal., mine.
The country rock is serpentine. Of course, only
after petrographical and chemical examination can
one say what is meant by " serpentine " in this case.
It has often been proved that not only have different
rocks been mistaken for serpentine, but also that
serpentine is not a primitive rock, but a product of
metamorphosis of olivine, pilirite, gabbro, and horn-
blende rocks. To obtain knowledge of the connection
existing between the cinnabar deposits and the ser-
pentine rock, one has not only to examine the petro-
graphical and chemical state of the so-called serpen-
tine, but also that of the rocks from which it has
been derived. The same will be the case with the
sedimentary rocks in contact with the serpentine.
Few of the Californian quicksilver deposits con-
tain native sulphur. They are not interspersed
in siliceous sinter, but form compact masses.
In their exterior appearances they offer no signs
of having been formed by ascending springs, al-
though from some of them carbonic acid and hot
water issue from fissures. In the vicinity of Sulphur
Bank, Cal., is an extinct volcano, 4500 feet high,
whose slopes are covered by trachyte and obsidian.
It is surrounded on all sides by hot springs, 72° C,
which exhale carbonic acid and sulphuretted hydro-
gen, and which precipitate borax, siliceous sinter,
and sulphur in large quantities. Especially the hills
on the southeast shores, which consist of tufa and
trachyte, have obtained the name of "Sulphur
Bank," as large deposits of sulphur are found on
them. Phillips found here decomposed volcanic rocks,
from whose fissures the above-named gases, also
steam and hot alkaline waters, issue. Sulphur is
found everywhere, and contains commonly a little sul-
phide of mercury. The walls of the fissures are some-
times covered with a layer of amorphous silica, below

which is a layer of chalcedony, and lastly one of crys-
talline quartz. These siliceous layers contain fre-
quently iron pyrites, and quantities of cinnabar, or
they appear to be covered with drops of a hydrocar-
bon. The places richest in ores are found to be those
where the rocks have been most decomposed by the
gases, and where they have been changed into a clay
with an acid reaction, and containing sulphur. Ac-
cording to this the mercury is first found in the
deeper regions of the decomposed tufa, where it
gradually changes into a sandy conglomerate of iron
pyrites, quartz, clay and cinnabar. The sulphur
springs in Colusa county also deposit siliceous sinter,
which contains cinnabar, and sometimes gold, as do
Steamboat Springs. The deposits of silica on the
walls of the fissures show a regular structure of lay-
ers, ore deposits in the course of formation, deposits
of a singular kind, and which only can be compared
to the small metallic deposits from solfataras and
fumaroles and from gas exhalation from the surface
of lava streams, all of which exhale sulphuretted
hydrogen.
There are probably no other ore deposits which
carry such an amount of native sulphur, and espe-
cially in lode matrix which is composed of silica, and
nowhere in the country a clay with an acid reaction.
A comparison with the true solfataras is here com-
plete, for these only exhale vapor, but no siliceous
alkaline water. On no other volcano has cinnabar
been observed in considerable quantity as a product
of solfataras or fumaroles. The product of fumaroles
consists, as a rule, of different bodies. The fumarole
products of the Vesuvius, which contain copper, co-
balt and lead, have their origin in the olivines and
augites of the lava, which contains these metals as
silicates, and which have been decomposed by acid
vapors ; the trachyte of Sulphur Bank may also con-
tain silicates carrying mercury. This is a question of
interest, as mercury has been found in the decom-
posed trachyte rocks of Hungary, Toscano and Peru ;
small quantities are also found in ore lodes of .propy-
lite in Schemnitz and Kremnitz, Germany. But even
then the presence of the hydrocarbons in the siliceous
sinter deposits is yet unexplained, nor is there any
explanation for the cinnabar-carrying sinter of
Steamboat Springs, which have basalt instead of
trachyte. It may be that the mercury ores and the
gold and silver of these springs have their origin in
older lodes, or in sedimentary rocks impregnated
with these ores, which have been dissolved by the
water and a second time deposited in the sinter.
This process would be similar to that in ascending
mineral springs which issue from lodes, and which de-
posit the dissolved metals as ochre. It is remark-
able that the sinter springs only deposit such metals
as are present in the older ore deposits of California
and Nevada, and also that they are accompanied by
hydrocarbons, which are never observed in siliceous
sinter, but which seem to be very frequent in these
older ore deposits of California, and whose origin may
be the sedimentary rocks leached out by the geysers.
Sulphide of mercury is easily soluble in alkaline sul-
phides and in sulphide of barium, as it forms with
these distinct compounds (RS HgS+5 aqu.), and this
at a temperature of 45° O, which is considerably
lower than that of the Sulphur Bank, 72°, which goes
to explain the leaching out of these older mercury
deposits by such waters. The solubility of sulphide of
gold in alkaline sulphides is also to be noted. Solu-
tions which contain, besides alkaline carbonates, also
alkaline sulphides, deposit first, on cooling, by former
dissolved silica, and undergo then, by contact with
the air, an oxidation to a thiosulphate, which further
is decomposed into native sulphur and a sulphate.
The large quantity of native sulphur of Sulphur Bank
is the result of the decomposition of the thiosulphate
and of the oxidation of the sulphuretted hydrogen.
The above-mentioned double sulphide of mercury and
an alkali also contributes, for it is decomposed into
an alkaline sulphate, sulphur and mercury sulphide.
The sulphide of gold, dissolved in sodic sulphide, and
deposited by the spring, is decomposed by the air
into native gold and sulphuric acid. This, at least, is
believed to be the way in which the siliceous sinter
and ore deposits of the Sulphur Bank and similar lo-
calities in California and Nevada are formed, so long
as it has been found that the trachyte of the Sulphur
Bank and the basalt of the Steamboat Springs con-
tain mercury in the form of primitive silicates.
A flining Decision.
In San Francisco this week the U. S. Circuit Court
of Appeals discovered and passed on a kink in the
extralateral endless chain of TJ. S. mining law, so
expensive to litigants, so full of promise to mining
lawyers. The law has only been in operation twenty-
eight years, and it is expected that before 2000 A. D.
is reached two or three other little points will be
made clear.
The case noted was brought up over the famous
old Tom Cruse mine, the Drum Lummon of Montana.
The St. Louis M. & M. Co. sued an alien corporation,
the Montana M. Co., Ltd., alleging trespass on the
part of the defendant and claiming damages. The
Montana court awarded damages to plaintiff in the
sum of $33,000. The plaintiff considered the sum in-
sufficient and appealed for a new trial.
The Court of Appeals on the 8th inst., in an order
of affirmance, says :
The question under present consideration is when
a secondary or incidental vein crosses a common side
line between two mining locations at an angle, and
the apex of the vein is of such width that it is for a
given distance partly within one claim and partly
the other, to whom does such portion of the vein be-
long ? This question does not appear to have been
ever directly passed upon by the courts. A mining
claim can have but two end lines, and, having been
once established, they become the end lines for all
veins found within the surface boundaries. This court
has already determined that the line E. C. D. shown
in the diagram introduced on the trial is a side line
common to the two claims, and, therefore, it cannot
be considered the end line of the Drum Lummon
vein. If, then, in construction of law the vein in the
25 feet in controversy must be either upon the one
location or the other, and if the senior location has
priority of title, it would follow that the right of
lateral pursuit would remain with the senior locator
within a plane parallel to the end line of the senior
claim and up to the point of departure of the apex ;
or, in this case, the front wall. Inasmuch as neither
statute nor authority permits a division of the cross-
ing portion of the vein, and the weight of authority
favors the senior locator, the entire vein must be
considered as apexing under the senior location until
it has wholly passed beyond its side line.
It is a travesty on human intelligence that such a
jumble of mystifying, expensive and vexatious "legis-
lation" as the U. S. mining "law" should be allowed
to continue. One of the principal reasons that so
many practical miners sniff at " science " as applied
to mining is because all this ridiculous jumble about
apex and apices and extralateral rights was put in
the mining law by "scientists." The miners them-
selves never had anything to do with putting this mass
of absurdity into the working statutes that govern
their affairs, and instinctively reject the hindrance.
The surprising thing is that public opinion permits
the continuance of such a law. In its relations to
modern mining, it is about the same as if an up-to-
date mine with a double-compartment shaft 2700 feet
deep should put up with a hand windlass for its entire
hoisting facilities.
Mine Consolidation.
A Colorado correspondent thinks that the tendency
to consolidation in gold mining in that State and else-
where is "a menace and an injury to our free insti-
tutions." He also thinks that they are "opposed to
the best interests of miners." His statements are
unaccompanied by argument and are mere asser-
tions, not backed by anything beyond expression of
personal belief. Without attempting to discuss the
bearing of the question on our institutions, free or
otherwise, but looking at the matter solely from what
might be styled the mining business point of view,
this paper sees nothing to add of relative value to
what it has already said on this subject — namely,
that the natural tendency of the times-is to make the
machine do all it can in actual mine work and to ele-
vate the man to make him more capable of directing
such work. A part of that tendency is to concen
trate and centralize.
In the case of adjoining mining properties, each
one with an entire nineteenth century system of
operation, separate plant, distinct administration,
etc., the twentieth century tendency is to have one
large organization operate and administer the entire
property as a whole — that is, if the ore now costs
$2.30 a ton to treat at one mine and $2.15 at an ad-
joining one, if the owners of both mines can come to-
gether on the same proposition to enable them to
treat all the ore of both properties for $1.95 per ton,
they figure they can make some money. In this, as
in everything else, the tendency of all legitimate min-
ing trends toward economy of production and opera-
tion, just the same as in the case of the department
store or the large manufactory. The plan in its
operation would tend toward the development of
other mining properties adjoining, unprofitable under
the present system, but of possible profit if worked
under more favorable conditions by a consolidated
management, which, by reason of its magnitude and
scope of operations, could work the present unprofit-
able property for much less cost than were it pros-
pected and developed as an independent proposition;
and if anything were found worth further exploita-
tion, it could be produced at a proportionately
greater profit by reason of the fact that it was being
worked by a company having other profitable prop-
erties adjoining; which is only another way of saying
that combined capital can make possible' what to an
individual would be impossible.

There are risks in mining investments as in any
other form of investment. It is, however, the busi-
ness of the intelligent investor who understands his
business to see that those risks are reduced to the
minimum. But as against the risks common to all
commercial ventures may be set the fact that the
mining investment is relieved of many onerous ele-
ments of risks attendant on mercantile investments.
Buying goods to sell again, notwithstanding competi-
tion, taking chances on bad debts, are things that do
not concern the mine operator but are among the
hundred attendant risks that must be taken by the
merchant.
The practical man makes the best theorist, for his
theories prove more feasible, being predicated on
substantial bases. Theory usually precedes prac-
tice, and yet the practice of theory is most satis-
factory and effective in the case of the practical men
whose theories amount to something. Nearly every
successful machine or device in mining or other work
is an example of practical application of mechanics
and design to theoretical ideas and discoveries.
To readers of the article by Prof. A. S. Cooper,
California's State Mineralogist, on petroleum, on
pages 437 and 438, will doubtless occur the thought
that California petroleum in the variety of its possible
by-products may be made worth even more by re-
fining and distillation than for fuel. Its great eco- •
nomic value is manifest.

Every' representative body of metal miners in conven-
tion in the last four years have rosolved in favor of
revision of the American mining law, and such pro-
posed revision has been variously drafted, but so far
none other than tentativo effort has been made to
secure legislation thereon.

gineers in San Francisco was in September, 1899 ; the

Utah miners say there is more profit in operating a
silver- lead mine now with silver at 635 cents than when it
was 90 cents an ounce. Improved and cheaper methods,
economic processes, reduced expenses, better transporta-
tion facilities, improved machinery, utilization of all mine
products, are among the stated causes.
It has been held (Lockhart vs. Wills, 50 Pac. Rep.,
318) that abandonment can not be charged against the
locator of a mining claim if, while he is in possession, and
before the expiration of the time within which he may
perfect his location under the laws of the United States,
the claim is seized by another, who holds possession ad-
versely to him.
Seventy-five per cent of the circulation at Nome

total value, about $64,000,000, of which gold constituted

"We need No. — , Vol. — , to complete our file of the

ance of having its business announcement referred to

Barium oxide at 700° C. takes up an atom of oxygen
from the air to form barium dioxide. This second atom
is given off at 1000° C, leaving the barium oxide. In the
commercial method of preparing oxygen by means of
this agent, it is heated to 750° C, under increased pres-
sure. The air is then withdrawn by means of a force
pump, causing the atom of oxygen to be given up. This
process is repeated until required amount of oxygen is
obtained.
Anyone holding a United States patent to mineral
land need do no further work upon it, nor is there any
further tax or expenditure so far as the federal govern-
ment is concerned. But a patented claim, like any other
real estate, is liable to local taxation. Sometimes such
local taxation is more than the $100 annual development
work would be, and. the likelihood of such taxation has
been a fruitful cause of delay in completing title to min-
ing property.
To men working where they are liable to be "leaded,"
whether in mine or smelter, barley water is recom-
mended as a corrective. It should be used right along.
A good antidote for lead poisoning is dilute sulphuric
acid. A drop in a glass of water should afford relief.
The ordinary case of lead poisoning is inhalation of the
oxide of lead, and the sulphuric acid in the water drank
immediately converts it into a sulphate of lead that
passes out of the system.
A ready method for determining the amount of
asphaltum present in bituminous rocks is afforded by
digesting the powdered rock with carbon bisulphide,
the asphaltum being thus completely dissolved out. As
oil shales and coal were found when treated in this way
to contain no asphaltum, the carbonaceous matter being
of animal and vegetable origin, it is concluded by some
that true asphaltum is of deep-seated origin, and results
from mineral reactions such as the double decomposition
of water and metallic carbides.
The Mount Bischoff mine, in the northwest of Tas-
mania, is, perhaps, one of the most remarkable tin de-
posits in the world. The average grade of the ore is 3%.
The concentrates average about 70% tin, yielding an
average of 68% in smelting. The crushing and dressing
expenses amount to about Is 3d per ton of ore treated.
This is considered the greatest tin paying mine in the
world. The Mount Bischoff plant is a combination of
sluicing and ore dressing appliances befitting its mixed
alluvial and lode character, consisting of a mill with
seventy-five stamps, Spitzluten and Spitzkasten, jigs
and round tables.
To determine silver in gold bullion by volumetric as-
say, one-half gramme of the alloy may be melted in a porce-
lain crucible over a burner or in the muffle, five grammes
of cyanide of potassium having been previously placed in
the crucible. When fused, two and one-half grammes cad-
mium are to bo added, and after perfect alloying with
the bullion the crucible is cooled and the cyanide dis-
solved in water. The clear button is then put into a dis-
solving bottle and 25 c.c. nitric acid of 32° added. When
the cadmium and silver dissolve the silver may be deter-
mined by sulpho-cyanide, or NaCl solution, after suffi-
cient pure silver is added to make the entire quantity
present about 1.004 milligramme. Such amount of pure
silver added is to be deducted in final determination of
tho silver contained in the bullion.
When diluting sulphuric acid with water the acid
should be poured slowly and carefully into the water,
while the mixture is constantly stirred. If the water be
poured into the acid, the heat produced where the water
and acid contact may occasion spattering. What is
called "marsh-gas," "fire-damp," etc., is a methane.
It is found in nature in petroleum, which gives it off
when the pressure of the earth is removed. It is of con-
stant presence in coal mines. It is a carbon dioxide, and
when mixed with air explodes if a flame or spark comes
in contact with it, being a constant cause of coal mine
explosions. The scientific article sent is mistaken, as
carbon is the principal component of this deadly gas.
Questions normally difficult to accurately answer
are sometimes rendered still more difficult by the lack of
detail in the question or the possibility of latitude in the
surroundings. An example of such latter style of query
is afforded in the simultaneous inquiry from Lillooet,
B. C, and Silverton, Colo., desiring "Concentrates" to
say : " Would gold which passed through a 60-mesh
screen be visible to the naked eye ? At what mesh would
gold be in such a fine state of division as to be almost in-
visible?" Off-hand, one might say in answer to the
first question "Yes." In answer to the second, "100."
But, manifestly, there are conditions that would make
such answers only approximately correct. Some men
have better eyesight than others ; what might be invis-
ible to one man might be distinctly visible to another.
A Trinity county, Cal., miner says he can see gold that
has passed through a 120-mesh screen. A Tooele county,
Utah, miner says it is hardly possible to make a mesh so
fine as to render the gold passing through it invisible.
Individual conditions have much to do with these
things. Gold too fine to be ordinarily visible in the pan
would become prominently visible with a background of
ebony, or black tile, as used by some miners. The ques-
tion, of course, hinges on the idea conveyed by the elastic
term "visible."
The Ashcroft process has been repeatedly described
and illustrated at great length in this and other
technical journals. Its most extensive use has been
in treatment of the refractory lead-zine ores of
the Broken Hill mine, New South Wales. This ore
contains 30% each of lead and zinc as sulphides,
and 25 to 30 ounces silver per ton, the sulphides
being so intimately mixed as to render separation
by concentrating machinery commercially impossible.
The ore is ground and roasted, then leached in suitable
vats with a solution containing per. salts of iron and
salts of zinc. The iron is precipitated as ferric hydrate
by the action of the zinc oxide of the ore, while the latter
passes into solution as sulphate of chloride. The iron re-
mains partly in the leaching vats with the lead and sil-
ver and partly separates on heating the effluent. The
residue is smelted for the two latter metals in the usual
manner. The solution from the leaching vats, which
must be quite free from iron, is then passed through two
sets of cathode chambers, and one-third of its contents of
zinc is obtained as metal deposit on the cathodes. It is
now passed through the two sets of anode chambers of
the same depositing vats, in the first of which iron
anodes and in the second of which carbon anodes are em-
ployed. Solution of the anode with formation of ferrous
sulphate occurs in the former series, and oxidation of this
to the ferric state in the latter. The effluent from the
double series of vats is then ready for use again in the
leaching vats.
Where a person or company has or may run a tun-
nel for the purpose of developing a lode or lodes owned
by said person or company, the money so expended in
said tunnel shall be taken and considered as expended on
said lode or lodes, and such person or company shall not
be required to perform work on the surface of said lode
or lodes in order to hold the same. The annual labor of
$100 on each claim may be performed under the above
section by work done on a tunnel, cutting, or which is
driven to cut, such claims. The patent expenditures of
$500 may also be made in such tunnel. A party may
patent one lode on the line of his tunnel for each $500 of
labor spent in driving the tunnel. There is no provision
of law for patenting a tunnel site. But it may maintain
an adverse claim for the protection of its line and tunnel
rights. Every tunnel, whether a crosscut or run upon a
vein, is presumed to be for the development of lode
claims, and in each case its rights are very closely defined
by law. If the proper notice has been posted on the site,
establishing the boundary lines thereof, stakes set, etc.,
and the record only made, the work must be prosecuted
with reasonable diligence ; the land office rules that "a
reasonable diligence in prosecuting the work is one of
the essential conditions of the implied contract. Negli-
gence or want of due diligence will be construed as work-
ing a forfeiture of their right to all undiscovered veins
on the line of the tunnel." A tunnel may, like any other
kind of claim, be abandoned ; but neglect to work does
not effect an abandonment; such neglect only operates to
deprive it of tunnel rights along its line.

Machine Mine Rock Drills on the
Pacific Coast.
Written for the Mining and Scientific Press
by A. E. Chodzko.
Rock drills have come nowadays into such general
use that no mine claiming to have passed the pros-
pecting stage would be considered in working order
without them ; and while hand drilling is still and
probably will always be the only practicable method
under special circumstances, machine work is more
and more used for tunneling, for drifting, for sinking
and for stoping.
In this country, as in Europe, where mechanical
rock drilling originated in 1856 at the Mont Cenis
tunnel, it was from the start applied on a large scale
to railroad work ; and one would hardly recognize in
the trim little stoping drill of to-day a kin of the huge
and clumsy machines of yore, mounted on their pon-
derous carriages.
And yet these obsolete tools have marked such a
decided improvement in the time-honored methods
prevailing at that time that the wonderful develop-
ments of low-grade mining during the last third of
this century may be directly traced to the introduc-
tion of machine drilling.
A description of all the varieties of rock drills,
either of the reciprocating or of the rotary class, in
this country and abroad, would furnish ample mate-
rial for a good size treatise, a large portion of which
should be devoted to American machines.
Less ambitious is the scope of this paper, and the
writer will limit his attention to the rock drills ob-
tainable to-day in San Francisco.
Electric drills, much advertised in other parts of
the country, are not likely, at least in the near
future, to supplant the compressed air machines for
underground work on the Pacific slope ; at any rate,
they do not seem to have made dangerous inroads
into the field occupied by the latter.
It is not intended to take up the comparative argu-
ments set forth in favor of either. The fact is that
at the present date air drills are practically in exclu-
sive use on this coast, and it is thought that a short
description of these machines might prove interest-
ing to the mining reader, the more so as a majority
of them are of home manufacture, and have been de-
signed and improved with special knowledge of and
regard for local requirements.
When a machine of this class is put on the market
it is an almost invariable custom to introduce it by
sending a number of specimens on trial to various
mines, where the new drill generally works side by
side with other machines in regular use at the place.
Not only has it to withstand the same rough usage as
its older competitors, but, besides, it must make its
way to prominence against the natural prejudice of
men disturbed from their familiar work, to learn
how to handle the newcomer to best advantage.
It is not going too far to call it an unwelcome guest
with the miner, however favorably inclined the own-
ers of the mine may be, and the builder may safely
expect a tendency to emphasize the defects of his
machine rather than to overlook them.
After a while the drill is returned to its maker, if
not a complete wreck, at least more or less bruised,
and charged with an imposing array of shortcomings,
which will have to be made good before it is granted
the favor of another trial.
Not uncommonly will these modifications amount to
an entire remodeling of the primitive design, and
the ordeal is repeated, till finally the ambitious drill
comes out victorious on a last trial, which simply
means that it is now fit for practical use, a privilege
which it is sharing with a number of others.
Nor is now the drill maker entitled to what he
might consider as a well-earned rest. Competition will
hereafter require his constant watchfulness to outdo
every progress heralded by a rival builder, and while
a well-known firm is always solicitous, even at a dis-
tance, for the successful operation of its machines,
yet there is no questioning the fact that the local
manufacturer is more directly interested in per-
fecting his own, not only as a purely commercial mat-
ter, but also on the ground of professional promi-
nence among customers with whom he frequently
comes in personal contact.
Of the several rock drills sold in San Francisco,
some are made in the East and others are manufac-
tured in that city. All belong to the reciprocating
class.
In describing the construction of these machines,
from information furnished by the dealers and manu-
facturers at the writer's request, the latter -pro-
poses, for obvious reasons, to abstain from any ex-
pression of personal opinion as to the comparative
merits of the various features involved in their de-
sign.
There is no implied desire to advertise any particu-
lar make. It is simply intended to point out the fact
that this region is fully up to date in the matter of
rock drilling machinery.
The first machines to appear on the Pacific coast
were the old style Burleigh, brought here by Messrs.
Parke & Lacy about 1871. These were succeeded by
the Ingersoll tappet drill, brought out in 1876 and
1877 by John B. Reynolds of Reynolds, Rix & Co. Then
came the Ingersoll Eclipse, brought out by Reynolds,
Rix & Co. , soon followed by the Richmann, the first
rock drill of local manufacture (W. T. 6arratt& Co.),
which went out of use after a few years of existence.
Next came the National, brought out by Reynolds
& Rix. This drill and the Ingersoll Eclipse were the
standard machines on this coast for a number of
years, till the National was replaced by the Phoenix
drill, built in this city by Rix & Firth, and one of the
first representatives of the auxiliary valve system.
The Sergeant drill next made its appearance, brought
out by H. P. Gregory & Co.
Then came the Cummings drill, a machine of local
make, operated on the two-pipe system.
The Challenge drill, brought out from England,
made only a passing stay on this coast.
The Rand drill was next brought out by H. D.
Morris & Co., and with the Leyner, manufactured in
Denver and brought out by E. P. Allis & Co., and the
Sullivan, made in Chicago and brought out by Hen-
shaw, Bulkley & Co., represent the latest types of
imported drills on this market.
The Doble drill, the Firth, the two Giant tappet
drills of the Rand type, one manufactured by the
Compressed Air Machinery Co. and the other by the
Rix Engineering & Supply Co., are all machines of
local make, and close up the list at the date of this
writing.
The machine rock drills, whose particulars have been
furnished to the writer, and which will now be briefly
described, are :
Eastern made machines : Ingersoll, Sergeant, Sul-
livan, Rand; Leyner, of Colorado.
California manufactured machines : Rix Giant,
Compressed Air Co.'s Giant, Firth, Cummings.
All these machines are especially intended for un-
derground work, quarrying on a large scale being
only exceptional on this coast. • The same machines,
moreover, can be used for open air work, although
certain types of Eastern manufacture are more par-
ticularly recommended in those cases.
A comparison between the various designs will be
made more easy and more practical by a few re-
marks concerning the salient features of the opera-
tion of a rock drill.
Any machine whatever, designed for that purpose,
reproduces the movements of the hand driller,
namely :
First. — A sharp-edged steel drill or bit is projected
against the rock, by the rapid reciprocation of a
piston, to which it is firmly attached, and which
moves into a cylinder. Compressed air is admitted
into and exhausted from that cylinder by a valve
which controls the reciprocating motion of the
piston.
The first distinctive feature of a rock drill is there-
fore its valve motion.
In the early types of European machines built for
the Mont Cenis and the St. Gothard tunnels a special
motor was used to operate the valve ; it was simply
a double-acting piston engine, actuating a shaft upon
which a cam was mounted, connected with the valve
of the drill, which could, therefore, be operated inde-
pendently of the piston, and, namely, if the bit be-
came engaged in the hole. This system has long
since been discarded and was never used in American
machines, where the motion of the valve is always
controlled by the reciprocation of the piston itself ;
and this control is effected in either one of three dis-
tinct ways, all of which can be found in existing and
successful machines.
(a) In the tappet drills the valve is moved ' back
and forth over the ports by an oscillating lever or
tappet, whose position is reversed when the piston
comes in contact with it at the ends of its stroke.
This is the most positive connection that can be de-
vised. It is characteristic of the Rand drill and of
the two types of Giant drills previously mentioned.
(b) In this second variety the valve is cylindrical
and self moving, when air is admitted or exhausted in
proper time behind its ends, which act, therefore, as
pistons moving in separate chambers at both ends of
the valve chest. The admission and exhaust of air
into and from these chambers takes place through
posts or passages whose ends are alternately cov-
ered and uncovered by the piston of the drill. The
best known representative of this system is the In-
gersoll Eclipse, and among the above mentioned drills
it is characteristic of the New Ingersoll, of the Cum-
mings and of the Sullivan.
(c) Another device consists, as previously, in con-
trolling the admission and exhaust of air on both ends
of a cylindrical valve; but here the two ports used for
that purpose are open to pressure or to exhaust by
an additional or auxiliary valve, positively actuated
by the main piston. This system partakes, therefore,
of the two former ones.
Amongst the machines here considered, the Ser-
geant and the Firth are provided with this style of
valve gear.
As to the relative value of the three systems, it
would probably prove useless to draw well defined
lines, besides stating that the Eclipse device (b) is
possibly less subject to wear than the two others; all
of them have been for a long time and are still ap-
plied in many thousands of successful and efficient
machines. The last two are used simultaneously by a
prominent Eastern firm, while other builders, after
successfully making rock drills with auxiliary valves,
have now adopted the tappet system. So that a se-
lection between them seems to be a matter of cus-
tom or of individual preference more than anything
else.
Second. — If the drill were always beating against
the rock in the same position, it would soon become
engaged and wedged into the pieces of broken stone
detached from the bottom of the hole. It is, there-
fore, necessary to drill a round hole, and this is
effected by turning the piston and the attached drill
by a certain amount at each blow, so that the cutting
edge of the drill never strikes the same spot twice in
succession. This partial twist generally occurs on
the back stroke, although in some cases it has been
effected on the forward stroke. This motion also fa-
cilitates the cleaning of the hole of broken fragments,
and in all of the above-mentioned machines it is in-
variably produced by a rifle bar, which engages a
nut fastened at the back end of the hollow piston of
the drill, and which is provided at its back end with
a ratchet and pawl device, allowing the rifled bar to
turn in one direction, but locking it in the opposite
one.
The only variants in that rotating mechanism con-
sist in that with some machines, namely, the Rix
Giant, the Ingersoll and the Sergeant, the pawls are
carried by the back head of the rifle bar, and the
ratchet teeth are cut into the ratchet box or casing ;
whereas in the other machines the teeth are cut
around the head of the rifle bar, and the pawls are
inserted in the ratchet box. (Compressed Air Co.'s
Giant, Cummings, Firth.) The rotary device of the
Sullivan drill consists of rollers locking the rounded
ratchet teeth when turning in one direction.
Third. — As the hole becomes deeper, it is necessary
to move the cylinder forward, to prevent the piston
from striking the front head.
In early machines for tunnel work, and in modern
types more particularly designed for surface work,
means were provided for producing this motion auto-
matically. In homogeneous and hard ground, and
when a number of drills are working together, this
automatic feed is desirable and simplifies the at-
tendance.
Experience has shown, however, that in most cases
of practice, and, namely, for underground work, hand
feed is preferable, and this is exclusively adopted in
the machines presently considered. The only variant
is found in the feed nut, which is single in all of them,
except in the Rix Giant, where a double nut is used,
permitting by a relative motion of the two nuts to
take up the wear of the threads.
It appears, therefore, that in most cases a rock
drill can be characterized in a few words, respecting
its three essential functions, namely :
Valve Motion : Tappet, Eclipse or auxilliary
valve.
Rotary Device: Stationary or revolving pawls or
friction rollers.
Feed: Automatic or hand. Single or double nut.
The shell carrying the cylinder side guides and the
feed nut is attached to a column, with or without
arm, or to a tripod. Carriages are found only in
tunnel work and not in ordinary mining.
Special features of the shells will be pointed out in
describing each machine. So will the clamp, through
which the shell is fastened to the column or to the
tripod.
No reference will be made to columns or arms,
which are of practically uniform design in all cases.
Tripods will not be represented either, as with
very few exceptions they pertain to surface rather
than to underground work, and their description
would extend the scope of this paper without neces-
sity.
(TO BE CONTINUED.)
By-Products of Coke Production.
Considerable inquiry has been received regarding
the by-products of coke production. In addition to
what has been published, the most practical state-
ment noted of late is contained in an account re-
ceived from the New England Gas & Coke Co. of
Everett, Mass.:
" At Everett (a suburb of Boston) the New England
Gas & Coke Co. sell their sulphate of ammonia at 2i
cents per pound, and get about thirty pounds from a
ton of Cape Breton coal in the process of coking.
Assuming that only twenty-eight pounds of sulphate
of ammonia will be obtained at Sydney, and that the
selling price will be only If cents instead of 2£ cents
per pound, it will yield 49 cents per ton of coal. The
by-product ovens at Everett also obtain from a ton
of Cape Breton coal about twelve and one-half gal-
lons of tar, which is sold at 2 cents per gallon, and
about 5000 cubic feet of gas, which is sold at 20 cents
per thousand. At Sydney the surplus gas will be
used in the steel mill, and it is fair to estimate its
value at the cost of natural gas in the most prolific
natural gas districts of the United States, or 5 cents
per 1000 feet. This will give the steel mill as cheap
fuel as if it were located in a natural gas district. It
is calculated that the quantity of gas produced at Syd-
ney will be somewhat less than at Everett, as the coke
will be treated somewhat differently to suit the blast
furnaces, but it will not be less than 3000 feet, which
at 5 cents per 1000 feet will be 15 cents per ton of
coal. The quantity of tar obtained will be about ten
gallons per ton of coal, which at 1 cent per gallon,

half the price obtained in Bostou, would give 10 cents
per ton of coal. Thus the value of the ammonia, gas
and tar obtained from each ton of coal will be not
tees than 74 cents, while the cost of manufacturing
the coke and by-products will only be about 10 cents." j
Electric Mine Hoists.
The use of electricity in mining has reached an ad-
vanced stage of development in Cripple Creek dis-
trict, Colo., where the miner may eat a meal
warmed by electricity, in a room lit by electricity,
ride in an electric car to the mine, go down in a cage
run by an electric motor, talk through an electric
"Cripple Creek Standard," shown in Fig. 3. This
hoist is not especially designed to be operated by an
induction motor, but may be equipped with a railway
motor. The brake is of the band type : the gears of
close-grained cast iron, machine cut ; the shafts are
of steel, running in babbitted bearings; the drum has
removable bronze bushings ; the motor pinions are of
vulcanized fiber, or rawhide. The motor is set on
hard wood blocks, making complete insulation be-
tween the motor and hoist. The controller for vary-
ing the speed of the motor is of the street-car type,
adapted to the alternating current. The reversing
and speed control is effected
by the one handle of the con-
troller. In the 15 H. P. hoist
the frame is cast in one piece;
$150,000 or $200,000 had been taken out the pay
streak ceased, but there have been veins of moderate
size which have been worked very profitably by com-
panies for a long time. I think the best results are
to be looked for in the low-grade belts. They are
undoubtedly the most certain, and it is along these
lines, I think, that the greatest development is to
be made. Our mining facilities are very good. Of
course, we cannot prospect in winter, because the
ground is frozen, but all our mining is carried on in
winter as in the summer.

Not alone in Colorado but in other mining States is
electricity in daily use in great variety of form, both
for surface and underground work ; but in the dis-
trict specified conditions conduce to make it notice-
able.
In the matter of electric hoists, especially, Crip-
ple Creek affords example of progressive types.

well adapted for use in stopes and winzes. They are
furnished by the Denver Engineering Works Co.,
Denver, Colo., in 1, 2 and 3 H. P. As will be noted,
they may be operated by direct or alternating cur-
rent motors. The drum is driven by a flat
paper friction wheel and the hoisting, low-
ering and braking are controlled by one lever,
which throws the drum either against the revolving
friction wheel or against the stationary brake block,
while the motor runs continuously. The hoist frame
is cast in one solid piece. ■ The drum is of cast iron
with 6-inch flanges. All gears are machine-cut from
the solid. The motor pinion is cut from vulcanized
fiber, or rawhide. The hoists are furnished with
sheet iron housing if desired ; size of drum, 10" diam-
eter, 15" long; size of steel rope, j"; shipping weight
of hoist, without motor, 815 pounds. The capacity of
3 H. P. hoist with direct current motor is as follows:
1600 revolutions per minute ; rope speed, 150 feet
per minute ; load, 600 pounds.
The same concern also make what they style the
Nova Scotia, as reported in the Canadian Mining Re-
view, in discussing a paper by G. W. Stuart of Truro,
on gold mining in that province, R. W. Raymond said:
The indications which Mr. Stuart has given of a
revival of gold mining in this province and to a
greater depth is parallel with what has been occur-
ring in California, where, with energy and modern ap-
pliances, they are treating rock that was formerly
thrown away. I remember a couple of years ago en-
quiring as to the cost of mining and milling in Cali-
fornia, and I found they were able to extract
ore from the hard quartz vein 2509 feet from
the surface, and take it up to the surface and treat
concentrates for about $2.60 per ton, of which $1.25
went for mining.
Following, Mr. Gilpin said: The gold mining indus-
try of Nova Scotia has in the past consisted almost
entirely of operations in the small gold-bearing veins.
| Many of these small veins were not suitable for small
I local syndicates, because it was found that after
taken place before or after the completion of the
veins ?
Mr. Gilpin: After.
Mr. Raymond: Then in that case you began the
work in this province for 1000 feet below the original
surface when the range was formed ?
Mr. Gilpin: Yes, but as a matter of fact, we have
mines that have been opened on the entire thickness
forming the gold-bearing horizon.
Mr. Raymond: How deep have your high ex-
posures been worked ? And what is the aggregate
height above the sea that the gold veins are ex-
posed ?
Mr. Gilpin: Mount Uniacke is about 600 feet above
the sea, and veins have been worked there to a depth
of 350 feet.
Mr. Raymond: I only wish to bring out this point
to emphasize what Vancotta said. It is absurd to talk
about veins giving out when they were originally 5000
or 6000 feet higher than they are to-day. You start
5000 or 6000 feet below and then you wonder whether
it is going to give out. Eor instance, in California,
the mother lode runs with it, and it is crossed by
innumerable canyons. We run across the vein on the
top of the mountain, and then across the same vein
1000 feet farther down. The veins in the canyon
were poor and on the high mountains rich, and that
made prospectors feel that they gave out. It is only
within the last few years that we have found bedrock
at a depth of 1000 feet, and now they mine at a depth
of 5000 feet.
Mr. Edwards: In California the experience of our
miners had been that after going down 500 or 600
feet there did occur a barren zone and that continued
400 or 600 feet farther down, and when that barren
zone was reached the men of the mine ceased work.
But latterly they have tried it again and they have
struck pay ore still farther down and that is what they
are working on now, and as far I know they have not
reached the bottom of that pay zone yet. They have
reached down some 2000 feet, and they have 1200 feet
of continuous pay ore in depth.
Mr. Raymond: In older times when they went

Mr. Edwards:

Mr. Raymond:
rather than none.
Mr. Edwards: There was one man out our way
who only got 69 cents for years and years and still
they worked it.
Jas. Douglas, the president of the American Insti-
tute, in the course of some further remarks at
Waverly, said: Last year we visited the mother lode
in California. There we saw the marvelous ore de-
posit which in the early days enriched California, and
which had fallen into decadence, mines closed and
everything gone to wreck and ruin, the mother lode
supposed to have been exhausted. But better ma-
chinery, more skill and higher metallurgical science
was brought to bear upon it, and the prosperity of
the mother lode was never more assured tbafl j* \%
to-day.

Professor F. W. Putnam of Harvard University,
a leading American anthropologist, is traveling
through California, and says there are better hopes
of solving the antiquity of man in California than any-
where else in this country. The California gold-bear-
ing gravels in which the Calaveras skull, the Table
Mountain bones and a number of stone implements
are said to have been found, date from an antiquity
far more remote than any other known formation
which contains relics of men. An accurate scientific
demonstration that human bones or implements really
occur in the auriferous gravels will immensely increase
the known antiquity of man. Any miner or excavator
who can show to a scientist, in place in the auriferous
gravel, such remains, will make a discovery of high
importance. In the California University museum
are a number of stone implements whose finders have
made affidavit that they actually came from the
auriferous gravels, deep under lava flows, and among
the bones of extinct animals. Of fifty-eight distinct
Indian languages known in the United States, thirty
are native to California, which makes this State an
unrivaled place for investigation in aboriginal lin-
guistics. Meanwhile, this paper long since showed
that the Calaveras " prehistoric " skull was a myth.
Source and Origin of Values.
Increase of ore values with depth is always a
mooted question among miners. That ore bodies in-
crease both in size and value with depth is a dictum
held by many mining engineers, among whom are
Wm. A. Farish. In a report on a Cripple Creek,
Colo. , property he gives his reasons for such belief
and among other things, says:
" The values came from g"reat depth in hot water
solution under great pressure, the heat being gener-
ated by the dikes, and as the waters cooled off the
values were precipitated in the rocks and crevices.
These waters carried sulphuric acid which acted
upon and destroyed the feldspar and mica, replacing
them by silica, thus changing a pure granite into
what is locally called 'granite quartz,' carrying
values.
"Where the formation is solid and has not been
disturbed, continuous ore bodies are generally found
of varying lengths and widths in the veins, the ore-
bearing gangue being granite quartz and pure
quartz.
" Where the formation has been disturbed, the wa-
ters not being confined to a regular crevice or con-
duit have dissipated their weath in the surrounding
formation.
" This whole district was at one time — prior to the
dike era — covered by overflow porphyry, and at
present that portion of the district lying north for
a distance of about 2J miles and an equal distance of
east and west of the center of the north and south
line is in porphyry bounded on all sides by granite
walls, showing that there is a basin in the granite
filled by porphyry cut by the dikes of the district, as
above referred to. It is my opinion that some point
within the porphyry area an extinct volcanic crater
will yet be discovered. All the overflow porphyry
in the district, except in the basin referred to, was
scoured off by glacial action, and the granite rocks
from the surface down to several hundred feet in
depth were more or less moved and disturbed, which
is the reason that no great bodies of continuous ore
(except in rare instances) have been found above 300
to 500 feet in depth, the wealth carried in the water
being dissipated in the loose and broken formation.
"By the above I do not mean to infer that no
valuable ore was found above the depth indicated, for
there was a great deal of money taken out of the
veins which have been developed above 300 feet;
but the ore bodies, as a rule, were narrow and short,
and oftentimes did not continue in depth, while below
that depth the ore bodies have been more continuous,
longer, and as a rule of greater width and of more
uniform value.
' ' Reasoning from the above-known facts, it is my
opinion that as depth is attained, the quality of ore
will increase, and at the same time maintain its
present average values. By this I do not mean to
say that at different depths in any mine values will
not fluctuate, but I do mean to say the general
average quantity of ore will increase and values will
be maintained until great depth is attained.
"It is therefore my opinion that the veins will
carry values as long as the formation is cool enough
to permit of the waters precipitating their values."
Big Railroad Tunnel.
The Great Northern Railway tunnel, in the heart
of the Cascade mountains, is through. By Dec. 1
track will be laid and trains running. Work began in
January, 1897. It is 13,253 feet long and cost about
$4,000,000. It is 53 feet over 2J miles in length.
There were approximately 800 men employed for
nearly three years. They cut the tunnel from both
ends at once ; the progress through the solid rock
averaged about 8 feet for every working day for
each gang of workmen. It therefore required fifty
men one working day to cut 1 foot of the tunnel. It
is 23 feet high, 16 feet wide ; the entire interior is
lined with cement. The rocks that were blasted were
ground into powder and mixed with the cement. The
steam locomotives will not pass through the bore ;
an electric engine will pull the trains from one end
to the other. This is made necessary on account of
the coal smoke from the locomotive. The tunnel was
designed and built under the supervision of J. F.
Stevens. The difference in alignment was about one-
fourth of an inch ; the error in the grade was 2i
inches.
The greatest quantity of iron ore mined in any
country in one year, up to 1899, was 19.4 million long
tons, the output of the United States in 1898. This
figure, however, has been eclipsed by the record of
1899, made up and announced by the Geological Sur-
vey. In 1899, according to that authority, our pro-
duction of iron ore reached the total of 24,683,173
long tons — an increase of 27% over the record mark
of the previous year. The total value at the mines
of the ore was $35,000,000, or $1.42 per long ton.
The average value in 1898 was $1.14.

Working an Asbestos Mine.
At Thetford, near Sherbrooke, Ontario, Canada, are
the largest producing mines of high grade asbestos
in the world.
The mining is carried on in open quarries, what
is known as " the big pit " at Bell's mine being sev-
eral acres in area and about 150 feet deep. The
serpentine is drilled and blasted and is conveyed to
the surface by cableways and derricks. The first
task is the separation of the asbestos-bearing rock
from the barren rock, and this is done by hand pick-
ing. The portions containing asbestos are then
conveyed to the cobbing house, where old men and
boys knock off the long-fibered asbestos from the i
serpentine. Generally, cobbing is limited to
veins from 1-inch thick upward, the sepa-
ration of the asbestos carried by the thinner
veins being done mechanically.
The mechanical separating process is a
simple one. From the cobbing room the rock
is deposited in chutes leading to a battery of
rock breakers below. At Bell's mines gy-
ratory breakers of the Gates type are em-
ployed, and from them the coarser fragments
pass to a set of crushing rolls. From these
rolls the crushed rock passes on to travel-
ing belt picking tables, where boys standing
alongside pick the fragments of barren rock
off the belt and throw them to one side. The
mineral bearing fragments pass from the
picking tables to cyclone pulverizers in which
the final crushing is performed and where a
current of air separates the light asbestos
fiber from the heavier rock dust. At various
points between these crushing and picking
operations the material is screened, and
finally the abestos fiber is screened from the
fine dust and finely broken fiber. The opera-
tion is a continuous one, the rock passing from
the top floor downward through the various
processes until the final product— commercial
asbestos — is turned out at the ground floor.
Except for the work of the boys at the pick-
ing tables the operation is a mechanical one
throughout.
The separated asbestos is divided into three
grades for the market. The first grade com-
prises the long-fibered material which is sepa-
rated by cobbing. The two other grades are
similarly determined according to length of
fiber, color and freedom from foreign matter.
The material not good enough to be included
in any of the three commercial grades, but
which contains fiber, is called "waste" and
really constitutes a fourth grade. The sorted
asbestos is packed in bags of 100 pounds ca-
pacity for the market. At the Thetford mines
about two tons of commercial asbestos is ob-
tained from every 100 tons of rock which is
crushed. Altogether about 600 men are em-
ployed in the mining operations of three com-
panies working the deposits at Thetford.
steel. With the new process, he says, any piece of
steel may have its tensile strength increased from
40% to 75%. ' ' It can be made so hard that no tool
will scratch it, and only a diamond can be used to cut
it. Yet it can not be cracked or broken by impact.
The harder the steel is made the greater and more
dense its tensile strength becomes." Railroadmen
say that, if so, Depoy has discovered the very thing
that railroads have been searching for in vain for
years — a process by which steel rails can be hard-
ened to resist the wear and tear of heavy trains with-
out becoming so brittle as to crack easily.
Of Increasing Use.

Progress at the Anaconda.
At the property of the Anaconda Copper
M. Co., Montana, each mine has machinery
for handling ore from a depth of 3000 feet.
The old style hoisting ore with cars is aban-
doned; ten-ton self-dumping skips have re-
placed them. The skips are either hung
above a double-deck cage or below, to suit
the arrangements of the skip bins at the sur-
face. By having cages in connection with
these skips, every time the skip makes a trip
a load of ore can be hoisted, besides two cars
of waste or deck loads of men, and, in conse-
quence, no men need wait for a cage for any
length of time. The skips are loaded at the
different stations, from fifty-ton ore bins, in
a few seconds. The gates are operated by
compressed air. The old way of using cars
was dangerous for the station tender, in
pulling the empty cars off and pushing the
loaded ones on the cage, besides being hard
work. Now he pulls a lever and the skip is
loaded. The sinking of the shaft is done by
direct hoisting engines, capable of sinking 1000
feet from one place. The old wooden gallows-
frames have been replaced with steel struc-
tures from 60 to 100 feet in height. An important
consideration in the building of steel gallows-frames,
engine houses, etc., was to guard against fire. The
steel frames are incombustible and there is.no lumber
above the shaft.
The company has in most places high-pressure ma-
rine boilers. The boiler houses are of steel. All the
machinery underground is run by air. All the large
underground pumps are furnished with air instead
of steam, keeping the mines cool and comfortable.
No vacuum pumps are now needed; these were
formerly a great expense, on account of the acid
water. Most of the pumps are of the Corliss type.
The column pipes are wood and lead-lined.

styled, is becoming a familiar object in the streets of
many principal cities. Like the bicycle, it is evolu-
tionary, and there are constant improvements.
Among those noted are the styles furnished by the
Locomobile Co. , a self-propelling steam-motor vehicle,
with little noise and no odor or vibration. The body
contains the boiler, engine, gasoline and water tanks.
The gasoline is carried in a copper tank under the
footboard ; it is forced by compressed air through
the boiler, where it is vaporized, and thence to the
burner, where it is ignited. The steam is generated
in an upright copper boiler ; water is supplied by a
direct-action pump connected to one of the cross-
heads of the engine. This pump works continuously
when the vehicle is in motion. The running gear con-
sists of two steel-trussed ball-bearing axles, con-
nected by a double reach ; the front wheels con-
nected to their axles by several joints ; the rear axle
composed of two parts passing through the rear
tubing. Fig. 1 illustrates the "Runabout," Stan-
hope model ; Fig. 2 a different make with buggy-top;

Explosives — Constant Care Necessary.
In spite of the quantity of explosives used in mining,
in spite of the special instructions issued with every
packet, in spite of the lessons taught by former acci-
dents, it is a sad truth that injuries from dynamite
and its kindred explosives continue to furnish about
one-third of the total number of accidents for the
year.
Nitro-glycerine and other high explosives are not
dangerous so much by themselves and under normal
conditions, as from the fact that they have to be ex-
ploded by percussion, by means of a detonator con-
taining fulminate of mercury, which is a very sensi-
tive medium. We have, therefore, these rules :
Never keep dynamite in the same box as the de-
tonators.
Never clean a detonator with a hard substance,
such as a pin, or even a straw, merely shake the
sawdust out.
Never bite the cap on to the fuse, but use a pair of
pliers.
When using powder, it is necessary to tamp very
tightly, hence copper bars are allowed ; iron bars
being prohibited, as they emit sparks when struck on
the side of the holes. Many miners still cling to the
superstition that dynamite must be tamped like pow-
der and, therefore, use a copper bar. This should be
prohibited, it is not necessary, and is very danger-
ous, for if the bar slipped out of the man's hand when
pushing the primer home, its falling weight is quite
sufficient to explode the detonator. Hardwood sticks
are all that are required and all that are permissible.
In all large mines the dynamite stored underground
should be placed in a specially constructed magazine,
under the charge of one man. The detonators being
in separate boxes well apart ; and a locked and cased
lamp kept constantly burning ; any one taking a
naked lamp into the magazine should be dismissed,
for if dynamite catches fire and burns away instead
of exploding, it generates excessive quantities of
carbonic acid and carbon monoxide — the one asphyxi-
ates, the other is a deadly blood poison ; and it may
destroy every man in the level.
Proper cases should be supplied for carrying the
dynamite from the magazine to the working places,
and contractors' boxes should have a separate com-
partment for the explosive, the detonators and the
fuse, and be provided with a strong hinged lid.
In charging holes underground explosives should
never be mixed ; it is absolutely useless since the
quicker explosive will do the work, and it may be
dangerous by setting up chemical reactions and gen-
erating deadly gases, which would not be formed in
excessive quantities by the one explosive. Never
drill out missed holes, never go back to missed
charges until some time has elapsed and never drill
into old sockets, as a plug may only partially explode,
or may coat the hole with a layer of active explosive.
Neglect of these simple and obvious rules has erected
a city of tombstones over the bodies of the hapless
and foolish victims.
When firing holes all approaches to the place should
be carefully guarded to prevent any one from inad-
vertently approaching.
When firing charges there are three methods
adopted — by snuffs, by matches, and by spitting the
fuse. The most common and most dangerous is to
spit the fuse ; even the best fuses may have a bad
coil ; occasionally where the powder is unevenly laid,
the fuse will then " run " and explode the charge pre-
maturely. The usual speed of a fuse is 2 feet a
minute, but the writer has known an individual coil,
by one of the most reliable makers, run through 5
feet in twenty-five seconds ; hence spitting is dan-
gerous, as a man has no time to escape should the
fuse begin to crackle, a sure sign that it is running.
It is becoming very common to spit a fuse with
dynamite. The end of the fuse is split with a knife,
and a piece of dynamite the size of a pea placed in
this slit ; the dynamite is then lighted and ignites the
fuse. Some day the dynamite will explode, tem-
porarily or permanently blind the man, and while he
is groping about to find his way out the charg will ex-
plode and he will pay the full penalty for his temerity.
Firing with a match is done by splitting the end of
the fuse, inserting the head of the match and lighting
the other end ; this gives nearly three-quarters of a
minute extra time.
The best plan is to use a candle snuff ; each fuse has
a snuff placed under it, the miner lights them and can
retire to some safe place and wait until the fuse
burns through and spits. As soon as he sees they
have all spitted he can go away and there is no dan-
ger ; yet in spite of all this, and for the sake of sav-
ing two or three seconds, men will frequently juggle
with their lives.
In firing in shafts it should be compulsory to fire
with electric discharge. A man never knows what
may go wrong with the engine, windlass or ladders —
if he lights his fuses and anything should go wrong
he is like a rat in a trap, with no escape. In firing
by electricity the battery is never connected until
all the men are out of the shaft, and there can be no
danger ; it is also far more efficient. — T. R. Godfrey.

Characteristics of California
Petroleum.
By A. S. Cooper, Cal. State Mineralogist.
Petroleum oils from the different oil fields of Cali-
fornia differ widely in physical characteristics and
chemical composition. They may contain, chemically
combined, one, two or three of the following ele-
ments, sulphur, oxygen and nitrogen, and in widely
varying amounts, while in some rare instances these
elements may be absent. Oils in the same stratum
and a short distance apart may vary greatly. Fre-
quently a well when it first yields will give an oil of a
lighter gravity than that which it will yield when it
has been pumped for some time.
We may, therefore, look upon California petroleum
oil as containing the following substances in an un-
known state or states of combination : Carbon,
hydrogen, sulphur, oxj'gen, nitrogen and other sub-
stances in minute quantities ; these combinations
being very great in number and extremely complex.
The boiling point and melting points of the bitu-
mens are altered very considerably by the presence
or even by the traces of sulphur, oxygen and nitro-
gen. The presence of a greater or less amount of
these substances during distillation has an influence
on the distillate. Generally the larger the amount of
carbon, sulphur, oxygen or nitrogen an oil contains,
the greater its specific gravity, boiling and melting
points.
California petroleum is a mixture of a large num-
ber of hydrocarbons and a large number of com-
pounds containing hydrocarbons, combined with sul-
phur, oxygen, nitrogen and other elements.
The sulphur compounds usually predominate, fol-
lowed by oxygen, then nitrogen, and, last, the other
elements in smaller quantities. These sulphur, oxy-
gen and nitrogen compounds were formed at the time
that the oil was distilled from carbonaceous rocks by
the heat of metamorphism, or are substitution com-
pounds formed subsequent to such distillation by the
hydrocarbons coming in contact with these substances
under different conditions. Oil when exposed to the
air absorbs oxygen. When heated with the perox-
ides the peroxides are reduced to a lower state of
oxidation. Petroleum when exposed to sulphur va-
pors absorbs them ; when heated with the persul-
phides the persulphides are reduced to a lower state
of sulphuration. Prom the above it can be seen that
California petroleum is of a highly complex character,
containing a large number of hydrocarbons and hy-
drocarbon derivatives. When the sulphur, oxygen,
nitrogen and other elements are removed a number
of the remaining hydrocarbons must be unsaturated,
and unless these substances be removed from the
crude oil before, distillation, fractional distillation
does not give a true index to the composition of the
oil. Ultimate analysis is worthless to show the char-
acter of the oil.
All the hydrocarbons and their compounds with
other elements in California crude petroleum are
volatile. Some, such as benzine, are extremely vola-
tile, whereas asphaltum volatilizes with great slow-
ness. Natural gas is a volatile part of petroleum.
Like coal, the bitumens, oil and asphaltum, through
decomposition, are constantly giving off carburetted
hydrogen.
This decomposition is probably effected by acids,
alkalies and other oxidizing agents forming oxygen
compounds with the bitumens and liberating car-
buretted hydrogen.
Decomposition may also be effected by sulphurizing
agents forming sulphur compounds with the bitumens
and liberating carburetted and sulphuretted hydro-
gen. These oxidizing and sulphurizing agents are
formed by metamorphism and other chemical reac-
tion within the earth, and which came in contact with
the bitumens. Carburetted hydrogen may also be
generated from oil by heat. This gas is often found
issuing from vents in the ground in California, having
a temperature higher than the surrounding ground,
sometimes as high as 90° P.
One of the reasons that California petroleum oil
has such a high gravity is owing to the fact that the
formation in which the oils occur is tilted and broken,
permitting the escape of the gases. When California
petroleum is evaporated by atmospheric influences,
the sulphur, oxygen and nitrogen compounds remain
and are concentrated, and, if the process is continued
long enough, solid asphaltum is formed. After as-
phaltum is formed evaporation proceeds with exceed-
ing slowness. Heat accelerates evaporation. The
evaporation from an oil tank built underground and
kept at a temperature of 50° P. is far less than from
a tank built above the ground and exposed to the
sun's rays, which may often reach a temperature of
130° F.
If a petroleum oil having a specific gravity of 40°
B. be exposed to the heat of the sun in a shallow pan
it will decrease 20% in volume in a short time ; the
portion of oil evaporated being better for the
manufacture of gas than the part remaining in the
pan. This experiment is easily tried and very
convincing. Notwithstanding this loss by evap-
oration caused by high atmospheric temperature,
the oil producer stores his oil in dark colored
tanks which are exposed to the blistering beat of the
sun, and it is to be regretted his example in many
instances is followed by the gas manufacturer, if
the oil tank cannot be placed underground where the
temperature is low and fairly constant, it should at
least be shaded from the sun and whitewashed to de-
crease absorption of heat.
When a fresh supply of oil is emptied into a tank
which contains oil which has been stored for some
time, it should be introduced into the bottom of the
tank. The fresh oil, being lighter than the oil already
in the tank, has a tendency to ascend, and in doing
so it dissolves the heavy oil and will not evaporate as
rapidly as it would if placed on the surface of the
heavy oil.
Advantage is taken of the fact that asphaltum is
nearly an unalterable gurn to make many construc-
tions in which a plastic and unalterable cement is re-
quired. Usually California asphaltum contains from
5% to 9% of sulphur.
Some wells in California produce oils containing
paraffine, but they are so valuable for producing il-
luminating oil that their use for gas making is pro-
hibitive.
At Baku, in Russia, a tract of land less than twenty
acres in area has produced in twelve years 35,000,000
barrels of oil, and is still producing about 12,000 bar-
rels per day.
On the Laguna extension, or Zaca rancho, in Santa
Barbara county, California, there are large deposits
of bituminized sand exposed upon the surface. On
any one of several twenty-acre tracts at this place
the dimensions of the exposures of the bituminized
sand would show that it contains 8,000,000 barrels of
heavy petroleum of the consistency of molasses.
To make one barrel of that material must have
taken eight barrels of ordinary petroleum before
evaporation, so that on each twenty-acre tract is
now the remains of 64,000,000 barrels of petroleum
oil. The astonishing part of this is that it is seen
upon the surface and is not hidden beneath. There-
fore, in California as well as in Russia, there are
probabilities .of a very small territory producing im-
mense quantities of petroleum oils. The case cited
shows one at least of such places ; and there may be,
and doubtless are, many others of similar character
where the oils are still hidden.
Unaltered rocks of California cover an area of over
40,000 square miles. Bitumens occur in all geological
formations, from the plutonic, metamorphic or igne-
ous rocks up to and including the quaternary. It is
found saturating strata of sand and seamed shale
and as many as ten beds of shale can be seen on the
eroded sides of some of the anticlinal ridges of the
Coast Range. These sand beds are very irregular
as regards their thickness and the distance inter-
vening between them. Some are a few feet in thick-
ness, while others exceed 400 feet, and the shales are
from a few feet to over 500 feet in thickness.
When several sands are to be seen on the side of a
mountain, or when they can be traced upon the sur-
face of the earth by their outcrop, if bitumenized at
all, the bitumen will generally be in the geologically
lower beds; and when a sand contains bitumen, the
underlying sand beds are also liable to contain bitu-
men. At the present time nearly all the wells that
are being bored are in the vicinity of surface indica-
tions— to wit, oil seepages, outcrops of bituminous
rock and gas blows, all of which are signs that the
reservoirs of petroleum are leaking, owing to in-
sufficient cover. At present the wells are generally
shallow, but they will increase in depth in time, as
they have done in other oil fields.
The day is not far distant when oil territory will
be selected by geologists on account of favorable
structure and position, irrespective of surface bitu-
mens. The wells in this territory will have to be
drilled to greater depths, but, when productive, will
yield light oil. Owing to the large area, and the
thickness of the unaltered rocks, the great thickness
and the number of the oil sands in California, the
yield of oil in California in future years will be
enormous.
A comparison of the consumption of fuel oil with
that of coal shows 3.33 barrels of fuel oil to be
equivalent to one ton of good imported coal. Figur-
ing oil at $1.40 per barrel, and coal at $7.50 per
ton in San Francisco, it shows the cost of oil
to be $4.66 as against $7.50 for its equivalent in coal.
Moreover, the labor required to operate with coal is
far greater than with oil, in most instances being
nearly double.
The perfect cleanliness of fuel oil and the ease and
simplicity of supply and regulation, make it a most
desirable substitute for coal. As long as coal remains
at $7.50 per ton in California it cannot be expected
that oil will fall below its present price, not at least
for some time to come.
In the year 1899 there were 1,740,027 tons of coal
imported into the State of California ; to supplant
this 6,794,278 barrels of oil will be required. As the
supply becomes more permanent the uses of fuel oil
will multiply.
The removal of the gasoline, benzine and illuminating
oil leaves an oil with a high flashing point, which
would be less dangerous to use in a locomotive and
otherwise than a fuel oil of low flashing point. The
removal of the water also improves the oil for fuel
purposes, as it does not have to be evaporated by the
fire.
The asphalts in the crude oil are objectionable for
the manufacture of gas. When the asphalts are sub-
jected to the temperature necessary to gasify the oil,
sulphurous gases are formed (principally sulphuret-
ted hydrogen), and as the asphalts contain a large
percentage of sulphur, these gases are formed In
quantity and require a large amount of a purifier for
their removal. The presence of asphaltum also fouls
the checkerbricks in the superheater and carburetor
in making water gas, and the retorts in making
oil gas.
At present the market value of asphaltum is too
high for it to be economically used for either the man-
ufacture of gas or for fuel purposes. The large per-
centage of sulphur in natural asphaltums or in those
obtained as a residue in the distillation of crude
petroleum make them an undesirable fuel. During
combustion with oxygen the sulphur combines
with the oxygen to form sulphur dioxide. Sul-
phur dioxide in absorbing water or the vapor
of water, changes to sulphurous acid. By oxida-
tion, the sulphurous acid is changed to sulphuric
acid, which may lodge on the surface of the boiler
and attack the iron, forming sulphate of iron.
Through this action the sulphur contained in the
asphalt is a cause of corrosion in boilers. Owing to
the presence of sulphur, the fuel value of asphaltum
is small when compared with the other hydrocarbons
contained in crude oils.
The time is not very far distant when crude Cali-
fornia oil will not be used for the manufacture of gas.
Distillates will be substituted for crude oil for the
reasons given in this article. Therefore, it will be
of interest to know what action distillation will have
upon the crude California oils.
In Pennsylvania the upper half of the still is left
exposed to the air to facilitate decomposition. Dur-
ing the first distillation of crude California petroleum
oil, decomposition of any part of the oil should be
avoided. Consequently, the stills should be com-
pletely bricked in so that the vapors will be kept
fully heated until they escape to the condenser. In
the manner of cracking, as practiced in Pennsylvania,
there must be a great loss of heat from the exposed
surface of the still.
The laboratory and practice show that the distill-
ing, manipulating and purifying of crude California
oil must be totally dissimilar and different from the
methods in use in Pennsylvania, Canada and else-
where. Most of the crude California oils should be
distilled twice. From experiments made it would
appear that the vapors of the lower hydrocarbons
during distillation are contaminated by the decom-
position of the sulphur compounds contained in the
higher hydrocarbons, such decompositions being
caused by heat. Usually the higher the boiling point
of a distillate obtained during any one run of a still,
the greater the amount of sulphur compounds con-
tained in the same. In distilling oils containing sul-
phur, the main bodies of the sulphur compounds re-
main in the higher hydrocarbons. Owing to this ac-
tion, by repeated distillation, the sulphur compounds
are generally eliminated to a great extent, but
hardly ever completely, from the oil.
A distillate having a certain specific gravity, when
distilled under atmospheric pressure from crude pe-
troleum, may contain sulphur in notable quantity,
whereas a distillate of the same specific gravity when
distilled from the same crude petroleum oil in vacuo
may be comparatively free from sulphur. This is
probably owing to the fact that a greater tempera-
ture is required to vaporize the oil when under atmos-
pheric pressure than in a vacuo, this additional heat
decomposing the sulphur compounds. At ordinary
temperatures petroleum oil does not absorb sulphuret-
ted hydrogen when collected on the surface of
the oil.
If hydrogen at a high temperature, or in a nascent
condition, is introduced into the vapors of the light
hydrocarbons during distillation, the sulphur vapors
which are formed by the decomposition of the sulphur
compounds contained in the lighter hydrocarbons
combine with the hydrogen and can be carried from
the still ; but if the hydrogen is omitted, the sulphur
from the decomposition of the sulphur compounds
combines with the hydrocarbons to form complex
sulphur compounds which are removed with difficulty.
It is supposed that, when in a crude state and not
distilled, the lower hydrocarbons in the California pe-
troleum do not contain sulphur compounds to any
marked extent, but are sulphurized during distilla-
tion by the decomposition of the sulphur compounds
contained in the higher compounds.
The asphalts obtained by the distillation of Califor-
nia petroleum contain from i% to 1% of sulphur. Va-
pors of sulphur have a greater affinity for heated
hydrogen, forming sulphuretted hydrogen, than for
heated hydrocarbon vapors to form sulphur com-
pounds. When hydrogen is in a nascent condition it
will replace sulphur in the liquid compounds of sul-
phur and hydrocarbon by inverse substitution. The
activity of this action is increased by heat. At60°F.
the action is very feeble, but at 200° F. the action is
rapid, and at higher heats the action is still more
rapid.
As has been stated above, California crude petro-
leum is composed of a number of hydrocarbons and
hydrocarbon compounds, mutually dissolved one within
the other, and having different boiling points. Owing
to this they can be fractionally distilled so as to sepa-

Owing to the highly complex composition and great

considered only suggestive.
The Theory of Distillation by Steam. — Very many
substances which distill only slowly or with decompo-
sition can be quickly distilled and the decomposition
averted if a current of steam is passed into the space
above the boiling liquid or into the liquid itself. The
latter is the better, for it gives a longer surface
from which the vapor may come off, and also agitates
the liquid so that in case there is any sediment it will
not burn fast to the bottom of the still. Crude pe-
troleum may be cited as a substance volatile with
steam.
The reason why steam helps distillation may be ex-
plained by Dalton's law (the pressure, and conse-
quently the quantity of vapor which saturates a given
space, are the same for the same temperature,
whether this space contains a gas or vacuum).
Now, as steam carries out from the still the vapor
of the boiling petroleum, and allows more vapor to
take its place, this explains the increased speed of
the distillation by steam.
The vapor of the petroleum being removed, the
liquid is as free to evaporate as if no steam were
present — i. e., as if a vacuum was maintained ; but it
cannot be said that distillation with steam is the
same as distillation in a partial vacuum. It only
gives the same result as the latter. The decreased
amount of decomposition may be explained by the
vapor being quickly removed from contact with the
superheated liquid and the sides of the still.
Why would not carbonic acid, hydrogen and other
gases do as well as steam ? When any of the gases,
or their component parts, affect the petroleum it is
manifestly inadmissible. For instance, sulphuretted
hydrogen would sulphurize the petroleum, and the
oxygen of air would oxidize the petroleum. Many
gases could be used if *i they were practically con-
densible.
The volume of steam used is immense and con-
denses to water, which occupies TB-Vs of the volume of
the steam. Thus steam may be used to aid in the
distillation of the petroleum, which is not soluble in or
decomposed by water.
Crucible Furnace.
This invention relates to means of fusing, or other-
wise treating by heat, metals or other bodies in
crucibles by direct impact of a blow-pipe flame upon
them. For this purpose an arrangement such as is
shown in the accompanying figures is employed. The
crucible C with its metallic or other contents M is
placed within a furnace chamber having near the bot-
bzj

torn an outlet O leading to a chimney. Through the
top of the chamber centrally over the crucible there
is a vertical duct D, into which is led laterally by a
branch B a mixture of air with gas or combustible
vapor supplied by a pipe G acting as an injector noz-
zle, so as to draw in air. In the center of the duct D
a jet of air is directed downwards from a pipe A. A
flame of intense heat is thus caused to issue from the
duct D and to impinge directly on the material M in
the crucible, the products of combustion ascending
along the interior of the crucible wall, i passing over
its upper edge, and then descending outside the cru-
cible to the chimney outlet at the bottom of the
chamber, as indicated by the arrows. Through the
cover of the chamber there may be a number of holes
H controlled by a turning valve, for admission of air,
so that a flame is produced surrounding the crucible
and so accelerating the fusion of its contents.
Deep Well Working Head.
Herewith is illustrated the latest design of the
Smith- Vaile deep well working head of the differ-
ential type, considered by the manufacturers suitable

crank bearings of liberal area. The gears are of
charcoal iron, machine cut. The pinion shaft ope-
rates in ring oiling bearings. The connecting rod is
of steel, provided with bronze boxes at crankshaft

head connection. The crosshead operates in an ad-
justable shoe. A water box is also provided, and
there is located beneath the air chamber a check

The Manufacturer says: "For good or evil to
our manufacturers American coal is going to Europe
in rapidly increasing quantities. The immediate
cause is found in the Chinese and South African wars.
Markets held hitherto exclusively by English coal
have been opened to us. The superiority of our coal
for steam purposes has finally been forced home to
possible buyers. Had we been wise enough to build
and aid ships ten or twelve years ago we would be in
the Mediterranean with coal, ton for ton as cheap as
England. We have been too careless. There are
those who think and say we should husband our re-
sources in coal ; that a time will come when we will
want what we are now exporting, but that time is
many generations distant."
Boulders in Mines.
The finding of water -worn boulders at great
depths in mines has been a source of wonder to min-
ers, and has been the cause of some theorizing as to
how the boulders got there. A few such occurrences
have been noted by the journals, but doubtless many
such finds never found their way into the columns of
a paper.
Some twenty years ago an extensive bed of sand
and rounded, water-worn boulders was found in the
California mine at Central City at a depth of 500 feet.
Some time in the 80s a nest of boulders was found
in the Virgin lode on Republican mountain. The
boulders were firmly cemented in the gangue rock
and some 60 feet from the surface.
At a depth of 230 feet a large number of water-
worn boulders were taken out of the Brannigan lode
on Leavenworth mountain.
In 1880, while driving a level on the Shively mine,
a large number of rounded boulders were found,
varying in size from pebbles to those measuring 8 or
10 inches in diameter. They were found at a depth
of about 400 feet from the surface and were all
granite.
Boulders of galena were quite common at a depth
of about 125 feet in the Last Chance mine at Creede,
and boulders of eruptive rock, coated with a thin
scale of mineral, are common in the Bassick mine,
Silver Cliff.
Their occurrence is an interesting study for the
geologist. The only tenable theory advanced by the
miners is that they fell into the crevices before the
process of filling was completed. — Georgetown,

New Electric Furnace.
The newest thing in electrical furnaces is illus-
trated herewith, as noted in the N. Y. Electrical Re-
view. In the manufacture of calcium carbide and
other products in an electric furnace requiring high
temperatures the following difficulties have been met
with : The mixture to be heated partly escapes de-
composition when passing the region of the electric
current, while another part is whirled out of the fur-
nace with the gases arising during the electro-
chemical and thermo-chemical reactions. That part
of the furnace charge which passes the electric heat-
ing region undecomposed, together with a part of the
manufactured product, will in many cases suffer dam-
age by combustion, because it can not be prevented
from leaving the furnace in too hot a condition. By
this invention it is not intended to avoid a moderate
part of the furnace charge passing the electric heat-
ing region undecomposed, because by allowing a part
of the furnace charge to pass the furnace undecom-
posed this part will not only help to protect the fur-
nace walls against the action of the electrically heated
products, but it will also greatly help in keeping up
the necessary isolations ; yet all other difficulties
enumerated above will be done away with. In carry-
ing out the idea the usual electric furnace is provided
with a feeding hopper and electrodes. The lower
portion of the furnace, however, is surrounded by a
water jacket through which cold water is continu-
ously passed. This jacket cools the products of the
furnace as well as the undecomposed portion of the
charge, and prevents such losses as are unavoidable
when the products of the electric furnace leave the
furnace hot as they are and come into contact with
air. This is not only important for the ready prod-
uct, but especially for the undecomposed part of the
furnace charge, which in most cases consists of oxides
and carbon. Coming out too hot, the carbon will
catch fire and burn away

MINING SUMMARY.
ALASKA.
Id his report to the Director of the
Mint from the Nome district, special agent
Cabell Whitehead says:
"Of the new discoveries since last sea-
son, Topkuk, located on the beach 80 miles
east of here, easily takes the lead. From
a space not over 500 feet in length along
the beach to the tundra there was taken
out this spring botweon $500,000 and $600,-
000, all with rockers.
"Tho latest strike, and one which is at
present attracting much attention, is on
the Bluestone river, in the Port Clarence
mining district, something loss than 100
miles from Nome. One of the tributaries
of this river — Gold Run — is said to exceed
in richness anything known heretofore, it
being no uncommon thing to get from
$10 to $20 in a single pan. The creek is
entirely taken up.
"A source of gold which is attracting
much attention at the present time is the
ancient river beds along the head of
Dexter and Anvil creeks. Some of these
deposits are fabulously rich, nothing
richer having been found in the Klondike,
I am told, than some of the claims along
Nickkala gulch. The extent of the de-
posits, however, has not yet been proven
and another season will be necessary to
demonstrate their value.
" I incline to the opinion that these
ancient channels are the source of the
gold found in all the countries in this dis-
trict, as well as the gold taken from the
beach, and, if I am right in this opinion,
they should be very extensive, and may
add millions to the world's production.
I see no reason to doubt that during the
coming winter, when prospecting can be
done with the aid of thawing machines,
these channels will be located, and next
season will see a very largely increased
production.
"In my opinion, the future of this dis-
trict remains to be proven, with the
chances largely in favor of its becom-
ing in the next two years a very great pro-
ducer.
"My estimate of the production up to
this time is $1,500,000, with the chance of
increasing this production before the end
of the season to $2,000,000."
The Alaska-Treadwell M. Co. in Sep-
tember worked 40,658 tons ore, valued at
$47,483, and 671 tons sulphurets, value
$20,835: total output, $73,495. The ore
averaged $1.81 ; working expenses for

A few men are at work at the Argo-
naut. In the Bunker Hill the old shaft
has been retimbered to a depth of 655 feet,
at which point the old timbers were found
intact. By November 1st the shaft of
the Peerless mine will be down 500 feet.
At the Lincoln mine, Sutter Creek, at
the 1200 level, drifting north and south is
to be done.
CALAVERAS COUNTY.
At the Melones Company dam, near
Robinson's Ferry, 110 mon were at work
before the recent rains. Two centrifugal
pumps, capacity 240 and 180 inches, re-
spectively, kept tho pit free from water ;
threo steam derricks removed the gravel
and stone. The pit is 110 feet long, 50 feet
wide; height of dam when completed, 20
feet above low wator mark. The water is
to be taken out through a llumo 4x9 foet,
which, with a tunnel J mile long, will

Fairplay, will build a 5-stamp mill.
The Placerville Nugget says that the
river bed mine at Salmon Falls, which was
being developed by Messrs. Drew, Cohn &
Donnelly, has been abandoned. After
spending a sum of money they found they
were developing a worked-out claim. The
bod of the river was covered with several
feet of debris and there was no indication
on the surface that the river bed at that
point had ever been worked, but when
bedrock was reached various mining im-
plements were found instead of gold.

PLACER COUNTY.
A. Bordeaux is manager of the Ralston
Divide G. M. Co. 's property, a drift mine
in a territory described and illustrated at
considerable length in the issue of July
30, 1898. His nearest postoffice is George-
town, 30 miles away ; his supplies are re-
ceived at Summit station. A system of
ditches, when completed, will furnish
water the coming winter to carry on hy-
draulic operations that are expected to re-
imburse the company for its considerable
outlay. Felix Chappellet is president of
the company, which has acquired posses-
sion of considerable valuable property
which will be thoroughly developed. Mr.
Chappellet has already shown consider-
able nerve in such enterprises. When at
the Mayflower he determined that by
adopting a certain course the ancient chan-
nel could be found, and for this purpose a
tunnel 5585 feet long was driven through
hard slate at a cost of $150,000, with en-
tire success. That section has yielded
about $30,000,000, which is considered to
be but an index of the amount yet to be
extracted therefrom.
Sentinel : At the Occidental gravel
mine at Grizzly Flat, near Iowa Hill, the
main tunnel has followed the channel 350
feet. Crosscuts show a width of about
400 feet. At the Herman quartz mine,
near Westville, the new tunnel taps the

Studenraugh & Barta, 12 miles north-
east of Capistrano, have spent the sum-
mer running a tunnel 65 feet with a 7-foot
dike of what they think is tin ore in the
face. The local paper says assays indicate
that this ore runs from 3% to 6% tin. It
carries iron and traces of silver. This
property is about 20 miles from the Tem-

The Cherry Hill quartz mill, Cherry
creek, is in operation under management
of E. D. Baker.
SONOMA COUNTY.
C. Bell of the Socrates quicksilver mine
at Pineflat has had six retorts constructed
upon plans of his own whereby he figures
that 98% of the mercury in the ore
treated will be saved. The metal easily
vaporizes when distilled, and with this
vapor go the profits. Each of the six re-
torts is capable of treating 2700 tons of ore
in twenty-four hours if run at its full ca-
pacity. A new crosscut to the vein from
the main tunnel has discovered 5% black
oxide and quicksilver. Mr. Bell says the
ore newly exposed contains $1.75 gold and
three ounces silver to the ton.

Shipments of smelting and crude ores
concentrates and tailings from Blackhawk
to outside smelters and other points of
treatment for the last week of Septem-
ber were eighty-one cars. The entire
month's shipments were 304 cars — 5624
tons.
Register-Call : During September there
were shipped from the BlacklHawk depot
of tho Colorado & Southern| railroad 304
cars of ore, 5624 tons, representing the
shipments of smelting ore, tailings and
concentrates, to Denver and other smelt-
ers, and shipments of crude ore to outside
points for treatment. Manager J. W.

LAKE COUNTY.
The Leadville ore output at present is
about 2000 tons a day, and the advance in
silver is encouraging to mining men. An
advance of 5 cents an ounce would mean
an increase of $1000 a day.
Carbonate Chronicle: Leadville has
abundance of manganese ore, but competi-
tion is so keen that profits on shipments
to Chicago are very low. The demand for
all manganese ore is very great in the
East. The mines of Virginia, Arkansas
and other points can not supply it, and
the big iron and steel works must neces-
sarily go outside for their supply, and
shiploads are brought in from Peru, Rus-
sia and Cuba. In the smelting of man-
ganese, the separation from the iron is not
complete, two products being made —
speigeleisen, where the iron is more than
the manganese, and ferro-manganese,
where manganese is in lesser quantity
than iron. The main trouble about min-
ing the Leadville manganese is the ques-
tion of freight. Unless the ore is up to a
certain standard it will not pay to ship.
If a furnace could be erected at Lead ville
to reduce the manganiferous iron to a
ferro-manganese, about 40% of the weight
would be eliminated, and the product
could then be shipped with profit.

IDAHO.
ADA COUNTY.
A Boise case involving the right to cut
timber from mineral land is before the TJ.
S. Commissioner. Bidenbaugh & Ro9Si
were arrested on the charge of illegally
cutting timber from the public domain.
They admitted that the timber had been
cut, but under the circumstances claimed it
was not a violation of the law, which per-
mits the cutting of timber from such por-
tions of the public domain as is known to be
mineral in character and subject to entry
as mineral land only. The complainant,
E. T. Staples, claimed the mining prop-
erty from which the timber was cut. As
he desired the timber for his own use he
caused the arrest. The land being min-
eral in character, the U. S. District At-
torney caused the complaint to be dis-
missed. It has been supposed that the
holder of a mining claim was entitled to
the timber thereon. If the construction
that he is not be correct, the miner is
afforded no protection whatever with re-
spect to the timber. He furnishes the
proof that the land is mineral bearing and
any one can take advantage of it and cut
the timber off. It is likely a test case will
be brought soon with the view to having
the question definitely settled. Officials
at the land office are under the impression
that the mine owner could prevent the
cutting of timber from his claim. As
there is nothing in the law preventing the
cutting of timber from a mining claim,
however, the miner cannot secure protec-
tion through the criminal courts. His
remedy, if he has any, lies in a civil pro-
ceeding. Receiver Garrett of the Boise
Land Office says: "While the law per-
mits the cutting of timber from mineral
land, still the man who appropriates the
timber therefrom is not the sole judge as
to the character of the land. The gov-
ernment can at any time require him to
furnish proof that the land is mineral,
failure to do which would be followed by
proceedings in the federal court."

LINCOLN COUNTY.
(Special Correspondence). — Yellow Pine
mining district, in the southern part of
Lincoln county, southern Nevada, is very
slow in developing on account of lack of
facilities of transportation, lack of fuel
and water. One man, Allen G. Campbell,
has twenty-four patented claims in the
heart of the district. No work is being
done on any of them.
Mr. Newby, Deputy United States Min-
eral Surveyor, is surveying four claims
for patent for Mr. Ritchie of Pueblo, Colo.
The Keystone mine, in the past a noted
producer of the yellow metal, was under
examination during the past week by Cap-
tain Hutton of Los Angeles, assisted by
C. A. Beck of Goodspring. On the final
report will depend the reopening of the
mine.
C. M. Over, owner of the January cop-
per mine, on the eastern slope of Potosi
mountain, is pushing work in developing
the claim, crosscutting the vein and run-
ning a tunnel, at the same time extracting
copper ore averaging about 25%. This
mine has paid all developing expense, be-
sides standing an expense of $28 per ton
shipping and smelting charges, and mak-
ing for its owner a handsome net profit on
each shipment.
A. E. Thomas is making another ship-
ment of copper ore.
Bowen & Green, who have under bond
the Azurite copper claim for $5000, are
pushing work with three shifts, extract-
ing and shipping copper ores. Between
the copper vein and footwall, vein mate-
rial several inches in thickness, assaying
three ounces in gold per ton, occurs. Of
course, this is carefully saved.
The Green Monster, under bond to the
Hearst estate, Supt. Wilkinson, is show-
ing up fine, the ore assaying an average
of gold $5, silver ten ounces, copper 8%.
Work is being prosecuted with vigor.
Three shifts are employed, sinking and

cut from the surface tunnel is now out
2745 feet, having been advanced 30 feet
during the week. The face is again in
hard porphyry. General repairs to this
crosscut are still going on.
The Belcher says: On the 100-foot level
the north drift from the west crosscut has
been cleaned out and retimbered 11 feet
during the week, its total length now in
good repairs, 36 feet. The south drift
from the west crosscut on the same level
is now out 24 feet, having been advanced
8 feet during the week. The face of this
drift is in ore giving an assay value of
$15.61 per ton. On the 1100-foot level the
Belcher, Crown Point and Yellow Jacket
joint drift is being repaired.

BOX ELDER COUNTY.
(Special Correspondence). — The Vipont
mine, operated by the Salt Lake Mining
& Improvement Association, ships an oc-
casional car or ore, the last shipment of
twenty-three tons netting the Association
$2000, the product being silver in form of
native wire silver and chloride of silver,
with some sulphides. It is claimed the
property has a vein 7 feet in width. The
property includes a small concentration
mill which may be enlarged.
The Sierra Madre mining district, en-
compassing the section around Maguire's
peak, 10 miles north of Ogden, is attract-

developments there. A company of Michi-
gan men are developing the Uwanta group
and the adjacent El Dorado group is being
developed by a company of Californians.
The altitude of Maguire's peak is 9125
feet, that of the Uwanta and El Dorado
groups about 8800 feet. Each group is
being developed by a tunnel which cuts
into the same ore zone. The tunnels are I
about f of a mile apart, both trending
eastward. The Uwanta is being driven on
a 20% incline, is in 200 feet, all of the dis-
tance in ore. with drifts in ore at 75 and
150-foot stations. The ore zone is claimed
to be a sedimentary deposit, in contact
form, lying between dolomite lime below
and blue lime above. The ores comprise
a steel galena, associated with iron sul-
phides and lead carbonates, the gangue
being a siliceous material. The values are
said to run from 20% to 80% lead, 4 to 12
ounces silver and 50 cents to $2 gold to the
ton.
Ogden, Oct. 3.
IRON COUNTY.
(Special Correspondence). — The Ophir
mine management has straightened and
retimbered the old shaft and sunk it to 300
feet depth. A 50 H. P. gasoline engine
operates the hoist and a belt-driven com-
pressor. At present depth the ore is more
of a sulphide than that obtained nearer
the surface. The main object now is de-
velopment, and the only ore shipped is the
high grade, which is sacked.
The Johnny mill is operating on ore
from the Johnny mine, and considerable
development work is in progress in the
Stateline district.
Stateline, Oct. 3.
JUAB COUNTY.
(Special Correspondence). — Manager
Mclntyre of the Mammoth mine states
that the large ore chute, well opened on
the 800 level, will doubtless soon be tapped
on the 900 level. A connection has been
made on the 1700 level with the winze
from the 1600-foot level, the winze being
on the ore chute.
The May Day is developed by a tunnel
which crosscuts 700 feet to the ore body.
From the point where the ledge is inter-
sected, various drifts have been run which
exploit the ore on that level; at the breast
of the tunnel is a hoisting engine and a
200-foot shaft which sinks vertically on
the zone, there being drifts from the shaft
also at the 100-foot station. The station
at 200 feet depth in the shaft was recently
cut. The shaft cuts the ledge on the lat-
ter's dip between the 100 and 200-foot sta-
tions. The ores average about $5 to $50
gold, 30% to 53% lead, 10 to 22 ounces sil-
ver, the shipments of this grade running
from 300 to 500 tons per month. It is esti-
mated that there are about 10,000 tons of
milling ore on dump and in mine which
will, according to samples tested, average
13% lead, 9J ounces silver and $5 gold to
the ton. The building of a concentrator
to handle ores of this grade is to be con-
sidered. The May Day seems to be on the
same mineral zone as that on which the
Godiva, Uncle Sam, Humbug, Yankee
and La Reine are located.
The Yankee is opened by a 1300-foot
tunnel which crosscuts the formation, a
40-foot upraise from which taps the ore
body at 600 feet below the surface. Capt.
T. Egan, manager of the property, states
that a recent car of ore shipped ran 50.5%
lead and 47.5 ounces silver, and that a
still later shipment of two cars will aver-
age about the same. The Yankee is
owned by Salt Lake and Eureka parties.
The directors of the Lower Mammoth
M. Co. have levied an assessment of 5
cents per share on its stock issue to raise
$7500 for the purpose of liquidating in-
debtedness and to open up some known
ore shoots.
The Centennial-Eureka shipped thirty-
one cars of ore for the week ending Oct. 6.
There are 230 men on the payroll.
Shipments from Tintic district for the
week ending Oct. 6 amounted to eighty-
five cars of crude ore and eight cars of
concentrates, bullion shipments amount-
ing in value to $3500.
Eureka, Oct. 5.
(Special Correspondence). — The Queen
of Sheba mine, under bond and lease to
the Ibapah M. Co., composed largely of
Chicago parties, is 6 miles east of the Ne-
vada line, on the western slope of the
Ibapah range, and at 9200 feet altitude.
The location is 100 miles south of Toana
station, on the S. P., and 175 miles from
the Oregon Short Line Railroad at Stock-
ton. The mine is opened by tunnels and
winzes, the ore being partly free-milling
gold. The mill on the property was de-
stroyed by fire a few months ago, and now
a new 10-stamp mill, with concentrators
and cyanide tanks, is being erected. The
mill will be run by water, through 1400
feet of pipe, at 425 feet pressure to a 6-
foot wheel, producing 40 H. P. However,
steam power is also being provided.
There is an abundance of water in the
Ibapah range.

Bingham Canyon, Oct. 2.
(Special Correspondence). — The concen-
trating mill of the Fortune M. & M. Co. is
operating by electric power, transmitted
from tho Jordan Narrows plant, and is
crushing and concentrating about forty
tons of ore per day. Besides having a
crusher and two sets of rolls, the mill is
equipped with screens, four three-com-
partment jigs, two Wilfley tables and one
Frue vanner. The ore thus far milled is a
lead sulphide, carrying also silver values.
The product is divided into four grades :
That from the No. 1 jig compartment
yielding about 45% lead; No. 2 compart-
ment 30%, and No. 3 about 15% lead; the
table product runs an average of 25% lead.
The entire jig and table product is esti-
mated to carry ten ounces silver to the
ton. The highest jig product carries from
12% to 15% iron, the other grades run-
ning from 25% to 30%, which is allowed
for by the smelters at the rate of 15 cents
per unit. The ores carry a considerable
quantity of silica, which is largely elim-
inated by the concentrators. The jig and
table products also carry from 1% to 2%
copper and small gold values. The For-
tune Co. has a connection with the Dalton
& Lark tramway line, over which its con-
centrates are carried to the railroad and
supplies to the mine and mill. Elmer Hill
is manager of mine and mill.
The new upper and lower terminals of
the Highland Boy tramway line are being
constructed. The upper is at the en-
trance to the No. 7 tunnel at the mine.
The lower is at the railroad track in Bing-
ham canyon, the line being 12,500 feet
long. The carrying capacity of the line
will be 500 tons per day. The Highland
Boy smelter at Murray is also being en-
larged to increase its capacity to 500 tons.
The week's bullion product of the High-
land Boy Co. is given out as being 120,000
pounds, consisting of copper, silver and
gold, same being sent to the refinery at
Perth Amboy.
Shipments from the Silver Shield mine
at Bingham on the 6th inst. amounted to
three cars crude ore and two cars concen-
trates. The crude ran forty-two ounces
silver, 41% lead, 2.7% copper, $2.20 gold,
the concentrates yielding twenty ounces
silver, 27.4% lead, $2 gold and 2.7% copper.
Bingham, Oct. 4. Wasoott.
(Special Correspondence). — The Red
Wing output for some time has been run-
ning about four cars per month, wholly
the product of lessees. But from now on
the Red Wing Company will take hold,
with the idea of furthering development
and increasing production. The building
of a new concentrator is among the pro-
jects to be considered. The ores here run
high in lead carbonates and silver.
The York, next to the Highland Boy, is
driving a series of drifts from the incline
tunnel to get at its ore body, which car-
ries 25% lead, 3% copper and 10 ounces sil-
ver. The width of ore is about 3 feet.
Some shipments are being made. The
York is largely in control of A. J. Orem &
Son.

Sunshine, Oct. 4.
(Special Correspondence). — The West
Argent M. Co., has erected a concen-
trating mill, which, it is thought, will be
operatingby Nov.l. The mine is equipped
with crushers, rolls, screens and WilMey
tables. The ores carry silver and lead,
and the mill will run tifty tons per day for
the first few months. A. L. Jacobson is
mine Supt. and Frank R. Ball manager.
Stockton, Oct. 5.
(Special Correspondence). — The Hercu-
les mine is shipping regularly about eight
cars per month of silver-lead ore, the last
shipment running 58% load and nineteen
ounces silver per ton. The property is
now in charge of H. E. Zerbe.
The Utah mine, in Deep Creek sec-
tion, is shipping from fifty to seventy tons
of ore per month, which runs about 40%
lead and 200 ouncos silver. The ores are
carbonates.
(Special Correspondence). — The Honer-
ine now has five boilers, having an aggre-
gate of 350 H. P., and has pumping facili-
ties for handling 750 gallons of water per
minute, consisting of Cameron sinkers and
a Jeanesville station pump. The boilers
are at the tunnel entrance, and Supt. Rad-
datz states that they are to try the experi-
ment of conveying steam through 3450
feet of pipes to the pumps — that is,
through 3250 feet of tunnel and thence 200
feet down a shaft. This shaft sinks near
the ore body; drifts will be run from shaft
to the vein as soon as the shaft shall be
sunk 40 feet deeper.
Stockton, Oct. 6.
(Special Correspondence). — The West
Argent incline shaft is down 600 feet, the
base of which is below water level. Water
being pumped is sufficient to supply the
boilers and for mill work. Various drifts
are run at different levels. The incline
follows the dip of the vein. Veins run in
opposite directions, the richest ore being
found at the points of intersection. The
ore is a galena and carbonate of lead, with
good silver values with the lead. The
mill will doubtless be in operation in a few
weeks.
The Hercules is being worked by the
owners, which include T. H. Benton & H.
E. Zerbe, the latter being in charge.
The incline shaft is 380 feet depth, most of
the ore coming from the surface down to
the 200 level. As is characteristic of the
camp the richest ore here is found at the
junctions of the veins that run in oppo-
site directions. The ores consist of a lead
and iron carbonate, the principal values
being silver and lead. Besides the high
grade ore that is regulary shipped to the
smelters there is in the mine a large ton-
nage that could be classed as milling ore.
The Silver Coin mine, in charge of
Alex. Maze, has made occasional ship-
ments. A shaft will now be sunk 200 feet,
and from it a level will be run to the ore
body that was opened through tunnels at
a higher point. This will give a depth of
500 feet.
The Stockton G. M. & M. Co , owners
of the Ben Harrison and others, has a
bond and two-year lease on the property of
the Lion Consolidated, which joins the
former. The same lode runs through
both groups and plans are being made to
operate them through a new shaft which
is being sunk at a point some distance
down the hill below the old Lion shaft.
At present it is down 200 feet, and levels
will be run 300 feet to the Lion lode, cut-
ting it 200 feet below the old workings.
The workings of the Lion and Ben Har-
rison will be connected. In the future all
shipments will be through the new shaft.
A new boarding house is being built and a
force of sixteen men is at work in the
mine. H. D. Trenam is Supt.
The Bunker Hill is being worked under-
lease to J. C. Reynolds and associates,
who have been doing considerable dead
work, but have a small tonnage ready for
shipment. The ores carry silver, lead and
gold, with a small percentage of copper.
They are now drifting from the west end
of the lower level, 200 feet below the sur-
face. The values run about 50% lead,
twenty to twenty-five ounces silver and
$10 to $12 gold. Here and there is found
a rich streak of chalcopyrites. Mr. Rey-
nolds is also developing the Rush Lake
group of five claims, which he own9.
The Ada group is being developed by
F. J. P. Pascoe and others. Wascott.

BRITISH COLUMBIA.
The second payment has been made on
the Britannia group of copper mines, 28
miles from Vancouver, which are being
purchased hy tho Valentine syndicate of
London, England. The total amount now
paid ha9 been $10,000 ; the next payment,
$50,000, is to be made Jan. 1st.

At Savonas, C. E. Low of the Cinnabar
M. Co. has a deposit of cinnabar. A. J.
Colquhoun says: "About three tons of
high-grade ore, which I would estimate
should average 20% to 30%, are on the
dump and a fine showing in sight." If the
ore averages 1% it is all right. The "20%
to 30% " is a slight exaggeration.
At Slocan the Two Friends sent a con-
signment to Nelson for smelting. It sam-
pled 160 ounces silver and 33% lead, the
shipment realizing $100 to the ton.
P. Corcoran, representing Dan Burns
and others of San Francisco, bas bought
the Harris group, on White Fish creek, in

Paul Johnson of the Greenwood smelter
says it will be in operation by Jan. 1, 1901.
He says the bulk of Boundary ores can be
smelted without fluxing, and cites the
Grand Forks smelter, now treating 300
tons of ore a day in one furnace, without
using a pound of either iron ore or lime
rock as flux. Slag is not even used, and
only 10% of coke. The matte turned out
carries 38% of copper. Mr. Johnson says
that Boundary ore should be treated at a
cost of $3 per ton.
DUTCH GUIANA.
J. H. Abbott of Paramaribo tells Two
Republics that in washing for gold he has
occasionally found diamonds — small ones
— in the tailings, the last washings. In
diamond mining the largest stones lie
farthest down. Years ago a Mr. Fen-
nelly, who was interested in gold mining
with him, washed a large diamond from a
pan of gravel. "Negroes do the work.
We pay them 50 cents a day. It costs
about 16 cents a day to maintain them.
They can do work that a white man could
never do, and live. All the labor there is
contracted through the Government.
The Government becomes a partner to
the agreement, and any negro running
away knows that he must settle with the
Government. In gold mining we pay 5%
of our returns to the Government, and a
rental equivalent to about 1} cents per
acre per year.
"When I arrived at Paramaribo I no-
ticed the amount of gold brought into
town by black men — not native Indians,
for they worship gold as a god, and will
not use it for barter and exchange, but
black bushmen, men descended from the
African negro. I found them coming
down the rivers in dugouts, with bottles
filled with gold dust. I made an expedi-
tion inland to a native village called Wak-
abashee. The trip was by river and took
eighteen days. There I met an English-
man, the agent of an English mining com-
pany, who took me through the claims
his company was working. I found anti-
quated methods in vogue, and much con-
sequent loss and expense. They were not
using mercury in their sluices and fully
50% of the gold which entered passed
through and was lost.
" There are two gold belts, each about
25 miles wide, running from the coast in-
land across French, Dutch and British
Guiana. The French, being nearest the
seashore, was mined first. Then came the
Dutch and finally the English sections.
It was in the process of working those
parts of the belts which came in the Eng-
lish colony that the recent diamond finds
were made. It was purely accidental."

of the Mexican Central.
Goorgo Kislingbury, formerly of the De
La Mar, has a bond on a silver and gold-
bearing property in Oaxaca, and is now
operating it with 400 Mexican miners, tho
output going to custom smelters.
THE KLONDIKE.
Assistant Gold Commissioner Bell at
Dawson has empowered himself to put up
at public auction everything in the shape
of a mining claim or mining prospect not
otherwise ownod than by the Government,
and if such property is not sold at tho
regular monthly auction day in November,
which is the 2d of that month, it will all
be open to location by duly accredited
miners having regularly issued licenses.
In this list will be included those claims
and fractions on Bonanza, El Dorado and
Hunker creeks which were advertised
some months ago to be sold at auction,
but which wore withdrawn just before
the day of sale. It is thought that on the
various main creeks the number of new
claims will be from 5000 to 6000.

Obituary.
♦.
With more than ordinary regret is
chronicled the death of Alan Ward of
Alameda, Cal., in Kiachta, Siberia, in the
23rd year of his age. He was the son of
Capt. A. H. Ward, and went to Siberia in
the early part of this year in the employ
of an American mining company which
had secured some mining concessions from
the Russian Government. The caving of
a gravel drift occasioned injuries which
resulted in his death.

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co.'s Scien-
tific Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Wear Adjusting Nut for Vehicle
Axles. — No. 658,500. Sept. 25, 1900.
W. H. Holliway, Oakdale, Cal. The wear
between the boxes and axles of vehicles
soon makes the wheels loose upon the
axles, and it is necessary to provide some
form of adjustment by which this wear
can be compensated for. This invention is
designed for that purpose. It consists of
a nut having a screw-threaded interior to
fit the end of the shaft or axle, an exteri-
or set or shoulder for a washer which fits
against the end of the axle-box, and a
chamber intermediate between the seat
and the screw threads of such diameter
as to receive the end of the axle.
This interior chamber is fitted with a
coil or other washer against which the
shouldered end of the axle abuts when the
nut is screwed into place. By removing
portions of this washer from time to time,
the nut will turn farther upon the axle
and take up any wear between it and the
axle-box or like part.
Metallic Lathing and Fireproof
Construction for Buildings. — No.
658,497. Sept. 25, 1900. M. Carrick, San
Francisco, Cal. This invention relates to
lathing and finishing for buildings of that
class known as " metallic and fireproof
finish." The object of this invention is to
provide for the construction of complete
walls, ceilings and partitions in which
spaces are provided for deadening sounds,
means for protecting the plaster, making
the construction vermin-proof, means for
providing air and ventilating spaces and
passages through which conducting pipes
or wires may be carried. It comprises
essentially the parallel floor beams, with
intermediate transverse beams, strips
above the upper edges of the floor beams,
and a body of plastic material filling the
space and supporting the floor super-
structure. The lower surfaces are arched
and formed by metallic lathing, and a suit-
able plaster or other coating to complete
the ceiling finish. Suitable openings are
made through the metallic portions of the
structure to allow the plastic material to
pass through and unite.
Horizontal Earth Drill. — No. 658,-
495. Sept. 25, 1900. H. E. Williams, San
Jose, Cal. This device is designed to drill
horizontally through the earth. It is
especially useful for making connections
between water and gas mains and like con-
ductors which are laid in the street, and
the buildings or points at the sides which
require surface connections, and is de-
signed to enable such connections to be
made without disturbing the asphalt or
other pavement with which the surface of
the street may be covered. It consists of
a frame adapted to be set in the line of
the hole which is be drilled, a horizontal
journal shaft carrying the boring tool at
the front end, mechanism by which it is
rotated and means for clearing the hole as
it is bored, together with means for con-
stantly advancing the boring tool until it
reaches its destination .
Door or Window Ventilator. —
No. 658,935. Oct. 2, 1900. Peter Abra-
hamson, San Francisco, Cal. This inven-
tion relates to the class of ventilators for
window sashes, transoms, doors, and other
similar communications between apart-
ments and the outer air. It consists of a
frame fixed in the ventilating opening
having an outer fixed plate and screen
continuation. A supplemental frame is
fitted and hinged to the main frame and
has a latch by which it may be opened
and closed with relation thereto, said sup-
plemental frame having a plate and screen
continuation in reverse position to the first
named plate whereby a tortuous passage is
formed from the outside to the inside of
the apartment. A slidable frame moves
in guides upon the hinged supplemental
frame, with direction pulleys at the top of
said frame and cords connecting with the
slidable frame pass over the direction pul-
leys to a point within reach of the oper-
ator. These cords pass through tubes or
channels, and may be secured to holding
devices when the slide has been moved to
close the passage through the screen.

In an editorial on the rise of silver
Bradstreets in the current issue thinks
there is no longer any evidence of Ameri-
can speculative interest in silver. Han-
dled as the bulk of the product of Ameri-
can mines and smelters now is, by combi-
nations more or less allied in interest,
there is practically no opportunity for
speculation in silver. At the same time it
may be doubted if the present method by
which such a large proportion of the
white metal produced in this country is
put upon the market really makes much
difference in the commercial prices, owing
to the fact that the activity which pre-
vails in our copper producing industries
and in other sources from which silver is
produced creates a constant supply and
prevents any very marked holding back
of the current stock of the metal for the
purpose of affecting quotations. It may
furthermore be noted that the presence
of the silver coinage issue as one of the
elements in the present political campaign
in the United States can hardly be looked
on as having had any bearing upon the
action of the silver market either in New
York or London. The chances of an ad-
ministration in the United States favor-
able to a return on the part of our Gov-
ernment to a free silver coinage policy have
hardly been considered in the current
discussion by the European financial press
of the tendencies of the silver market or
been effective in connection with the re-
cent disposition it has shown to become
stronger and to advance.
One of the chief influences governing
the silver market has been the demand
for China created by the military opera-
tions and the suspension of the import
trade of that country. At the same time,
the leading authorities on the subject
give the first place to the demand of the
Indian government, and it would also
seem that the British financial authori-
ties have bought more or less silver for
subsidiary coinage in connection with the
large expenditures occasioned by the war
in South Africa. In fact, this South
African demand has been described as fur-
nishing the occasion for no small propor-
tion of the strength of the London silver
market during the last month or so. It
is to India, however, that most of the re-
cent buying of silver is attributed. The
government of that country has found it-
self confronted with a real scarcity of
rupees for circulating purposes. It must
not be supposed that the change in the
currency policy of India in recent years
has had any effect on the habits of the
native population of England's eastern
dependency. On the contrary, the Hin-
doos have gone on melting down rupees
for the purpose of personal ornamenta-
tion, and also have continued to hoard
the silver coinage in preference to
any other form of money or visible
wealth. This has resulted in a di-
minution of the supply of actual
money, and has forced the Indian govern-
ment to meet it by large purchases of bar
silver to be coined into rupees and put in
circulation. The Government and the ex-
change banks have both been buyers in
the London market, some of the recent
heavy purchasing orders being openly at-
tributed to the Indian Council for use by
the mints. At the same time, the more
satisfactory crop prospects and the better
financial position of the population of India
have tended to create a renewed demand
for silver bars, of which a considerable
quantity have been exported from London
to the East. According to the figures,
which are accepted as official, the total
shipments of silver from the British capi-
tal to the East up to the beginning of Oc-
tober have this year attained a value of
over £6,000,000, as compared with only
£4,000,000 in the corresponding nine
months of last year. Allowing for the in-
creased Chinese demand, these figures
point to a decidedly better absorption of
silver by India.

CROWN GOLD MILLING CO.
Manufacturers of the "CROWN" CONCENTRATOR and CROWN
ORE SIZER. A dry process of sizing and concentrating ore, sand or
gravel. Designed to accord fully with the laws of specific gravity,
and especially adapted to refractory ore or localities where there is
no water.
The chief claims for the Crown Concentrator are that it occupies
less floor space and has nearly four times the capacity of any wet
concentrator; that it will concentrate ores containing base and refrac-
tory metals that ordinarily slime and carry off values; that it effects
a saving of values far above the ordinary methods of concentration.
We have, now in operation, a complete plant
for crushing, sizing and concentrating ores by the
Crown Dry Milling Process.
Mine owners desiring tests made can forward
us, freight prepaid, not less than 1000 lbs. nor
more than 4000 lbs. of sample, for which a
charge of $20 will be made. (This amount in-
cludes assaying, etc.)
Ores for which this process is adapted and of
which consignments are solicited are any con-
centratable ores, pulps, tailings, or sands, carry-
ing sufficient values, whether they have hereto-
fore been profitably concentrated or not.

Pelatan-Clerlcl
Plant.
OF TREATING REFRACTORY ORES
Haves the precious metals by tbe simplest, most eco-
nomical and most efficient process known. No roasting or
previous treatment, except ordinary crushing. Extraction
complete In from 6 to la hoars. Extracts equally well
both One refraotory gold and coarse gold In the form of
amalgam. Makes a greater saving of gold than any other
process from raw material at less cost. The electric cur-
rent and dissolving agent promptly dissolve the preolous
metals, both gold and silver. Samples of ore tested free of
charge. Several mills saving over 90 per cent of valnes by
bullion returns. Simplicity. Economy. Efficiency.

THE IMPROVED BARTLETT CONCENTRATING TABLE.
The BARTLETT CONCENTRATING TABLE has been GREATLY IMPROVED recently by the substitution of iron
in place of wood wherever possible. It is now built with SOLID IRON TOP, PLANED TO A TRUE SURFACE AND
POLISHED ; all parts are made by template and EACH PART BEING INTERCHANGEABLE. As now constructed,
the table has no special wearing parts and will last for many years. It has a CAPACITY OP PROM FIFTEEN TO
FORTY-FIVE TONS IN TWENTY-FOUR HOURS, according to the class of ore worked. It is the only table in the
world which will take the place of jigs and do away with all costly and complicated machinery.
It is Especially Designed for Separating: Zinc from Lead.

GATES FINE CRUSHER.
The result of ten years' solid work. Success at last. What
we wanted, and the public demanded, was a Gates Gyratory Rock
and Ore Breaker (always adjustable and indestructible) so modified
in design as to make one-half-inch product from three-inch sizes,
rapidly and cheaply. The H. Fine Crusher will do this work. It
takes the place of expensive big rolls and often prepares ore,
without further crushing, fine enough for coarse concentration or
cyaniding. In any event, it is the greatest and best intermediate
machine between the coarse breaker and the pulverizer.

SMOOTH- ON
CASTINGS.
An iron cement for repairing leaks or fractures in steam or hydraulic work. When hard it will

THE GRIFFIN
THREE ROLLER
7VYI
The Griffin Threo Roller Ore Mill is a simp.y constructed Mill, suitable for working all kinds of ores that
require uniformly fine crushing by the wot process. This Mill is a modification of tho well-known Chilian
Mill, but the rollers run upon a crushing ring or die, which is inclined inwardly at an angle of about 30 degrees,
the rollers themsolves also being inclined to the central shaft of the Mill, thus utilizing the centrifugal force,
as well as the weight of the rollers themselves as a crushing agent. The Griffin Three Roller Ore Mill is there-
fore a Mill of great strength, and has few wearing parts. We construct these Mills with extreme care, using
only tho best of raw materials, which are most carefully worked by men who are specialists as mill builders.
We sell the Griffin Ore Mill on its determined merits, and will gladly supply full information regarding it to
any one.

In this advertisement we show cut of a recent Silver-Lead Cast Iron Water Jacket Furnace.
Some metallurgists prefer jackets made of steel plates, and under some conditions plate copper is
demanded, although more expensive. Most of the important smelters are using cast-iron jackets
now, hence we give prominence to that material. There are absolutely no conditions in blast fur-
nace practice but are as well subserved by propei'ly proportioned cast-iron jackets, as by those of
any other material.
Write for our catalogue, showing many different styles of smelters for the treatment of
QOLD, SILVER, LEAD, COPPER AND NICKEL ORES,
also the latest and best method for the economical use of jacket water (a saving of 80% to 90%
guaranteed) by our patented
WATER VAPORIZING ATTACHMENT.
We design, manufacture and erect Mills for Concentration and Amalgamation, Milling, Chlorination and Cyanide Processes. In writing for information, give us the
analysis or character of the ore to be treated, to enable us to intelligently arrive at the proper method.

The Ideal Conveyor Belt
Is the one that will carry stone, ore, coal, wet or dry
material, holding buckets firmly and securely; will
stand all kinds of exposure, and resist the heaviest
strains during a long period of service. This is what
the LEVIATHAN belt has done, and we quote the
following from a letter from the New York Steam Co. :
"We have used Leviathan Belting for four years, up
to 34-inch by 8-ply, elevating and conveying coal. Some
of the Belting is outside, exposed to freezing weather ;
some in a steam hath. In both conditions the results
have been very gratifying, over 500 tons having been
handled in ten hours time. '

Advantages of Elec=
trie Hotors.
They are capable of direct
connection to the machinery
to be operated, which means
that their power, however
great it may be and however
large the machine, can be
transmitted by the shaft in-
stead of requiring a belt and
a pulley on the driven machine
large enough to receive, by
the friction of the belt trav-
eling upon it, the needed
power. As 1000 feet of belt-
ing 1 inch wide must pass
around a pulley in a minute
to transmit 1 H. P., it is evi-
dent that the handling of 100
H. P. will require a large
pulley and a heavy belt, which
is not only inconvenient and
sometimes dangerous, but
occupies considerable floor
space, and requires that the
machine be heavy enough in
design to support the large
pulley and the strain of the
belt. Motors are capable of
regulation and control of
their speed and driving
power with great conven-
ience, so that electrically driven machines can be
started, stopped, reversed or speeded up by the
use of small instruments known generally as regu-
lators, which may be placed close to the machine or
in any other convenient location, while machinery
driven by belting can be merely started or stopped,
and then only with a considerable manual effort in
shifting the belt, or can be run at other speeds only by
bodily removing the belt to a driving pulley of different
size. Motors, when used for driving machinery, are
usually attached directly to the machine, and, being

much less bulky than other means of driving, the en- |
tire machine is independent of any line shafting, and
therefore may be located in a convenient position
without regard to this limitation, and in many cases
can even be picked up and shifted from one place to
another, as the exigencies of its work require.
Electricity permits the saving of one-half the
power otherwise required. This results from the
fact that when the tool is stopped the motor is
stopped and draws no power, whereas in belt
driving when the tool is stopped the belt or one

of the belts is simply shifted and continues to run
on an idle pulley.
Increasing Business.
The general advance in the manufacturing indus-
tries of San Francisco and California is typified by
such enlargement of manufacturing facilities as that
of the Geo. E. Dow Pumping Engine Co., which on
the 1st inst. moved into new and larger buildings.
For twenty years the Dow Steam Pump Works have
been manufacturing pumping ma-
chinery at Nos. 108 to 120 Beale St.,
San Francisco, and in modernizing
methods of construction it was found
requisite to have larger and better
surroundings. The accompanying
picture gives graphic representation
of the appearance of the new shops
and offices of the new company, ex-
tending on First street, San Fran-
cisco, from Natoma to Howard
street, and on Howard from First to
Fremont, giving the company about
50,000 square feet of floor surface.
The offices of the company are at
179 First street. The specialties of
the company are steam, electric and
power pumps and hydraulic machin-
ery ; the Dow pumps are found on
several United States battleships
and cruisers. Dow pumps were on
the great battleship Oregon, built
by the Union Iron "Works of San
Francisco ; Dow pumps are on the
battleship Wisconsin, similarly built,
that beat the world's record in her
official trial trip in Santa Barbara
channel on the 11th inst.

Purchase of the Guggenheim smelting interests by
the American Smelting & Refining Co. is again
asserted, the consummation of the deal to be an-
nounced before Jan. 1. When the smelter combine
was formed eighteen months ago effort was made to
include the Pueblo, Colo. , plant and the several Mexi-
can establishments of the Guggenheims ; but the
proffered price was considered insufficient by the lat-
ter. Negotiations have since gone on, and it appears
probable that the consolidation will be effected before
the close of the year. The figure mentioned, how-
ever, $38,000,000, is manifestly an exaggeration. A
proposition that had been the subject of considerable
negotiation was based about as follows : The Guggen-
heims to get for all their interests $35,000,000 of
American Smelting & Refining Co.'s stock, half in
common, half preferred, and they to pay the Ameri-
can Smelting & Refining Co. $10,000,000 in cash. If
the preferred stock were quoted at 90 and the com-
mon stock at 40, $17,500,000 of each would be worth
$22,750,000, and if the $10,000,000 in cash were de-
ducted therefrom, it would represent $12,750,000 as,
approximately, what the proffer would net the Gug-
genheims for their holdings on that basis. It is prob-
able that their properties will be so absorbed.
It is expected that when cessation of hostilities
enables resumption of gold mining in the Transvaal,
the value of the properties will be enhanced, because
of a direct saving per ton of ore treated and an in-
crease in the tonnage mined. Among other antici-
pated economies are counted the cheapening of the
cost of labor and supplies, the suppression of the
dynamite monopoly and the ceasing of the traffic in
stolen amalgam. It is expected by the sanguine that
the ultimate result of such aggregated savings over
the former system will represent an increase in
annual dividends of over $25,000,000, based on the ton-
nage of ore crushed in 1899. Those who figure that
way apparently overlook that while the result may
be a lessening of costs, it must necessarily be some
time before the dividends can be expected to greatly
materialize, as the British Government will naturally
expect that much of the cost of the war shall be
borne by the industry that that war relieved from
some of its former restrictions. Now that the South
African Republic is no more, it is possible that the
cyanide patents may be brought forward in that
English colony. The Dutch courts held the Mac-
Arthur-Forrest patents to be invalid; but the general
recognition of those patents in British courts may
serve as a precedent in the Witwatersrand, which
now becomes a British colony, and where 35% of the
gold recovered is by the cyanide process.
Business, Not Politics.
A little local item in the issue of the 10th inst. of
the Mother Lode Magnet, a paper published at
Jamestown, Tuolumne county, Cal. , is one of the best
bits of mining news seen for a long time. It is a
brief statement to the effect that Tuolumne county,
Cal., supervisors are making repairs on the roads
under their control. Ordinarily, whatever is done
for the miners in the way of good roads, or any roads
at all, is done by the miners themselves, at their own
individual expense, and there is' nothing that so re-
tards mining development in the State of California
to-day as the lack of roads. "No thoroughfare"
might be written in a great many instances as the
cause of the languishing or death of many a promis-
ing mining district in the State. It has not been un-
common for mining men for six months in the
year to come into this office declaring that they
would be eternally blest if they ever went near such
and such a locality again ; that they would prefer a
trip to a point a thousand miles distant, because of
the discomfort and delay attendant upon a lack of
communication, at the same time telling of wagon
loads of machinery blocked and mired along the road
they traveled, and giving details of the expense con-
sequent upon such a state of affairs.
Comment has been made on this before, and the
subject is reverted to now only to say that very often
it is the fault of the miners themselves. They have
the control of these things in their own hands, and
with organization and proper use of their votes they
could vote supervisors into office that would see that
the roads were bettered. This suggestion is con-
sistent with our invariable rule never to have any-
thing to do with politics, but there is no partisan
politics in this ; it is purely general ; it is for the
greatest good to the greatest number. Too often
men are influenced by partisan pleas and elect a man
because he is a good fellow, or because he needs the
office, or because he belongs to their party, or be-
cause they believe lies that have been told about his
opponent; but, viewing the voting as a business prop-
osition, it is good business for the miner everywhere
to vote for and stand by the man that he has pretty
good reason to believe will work for and stand by
him. When we say "the miner" we mean every-
body in any way connected, directly or indirectly,
with the prosperity of the mining industry, and who
look to it, directly or indirectly, for aid in their busi-
ness. It is the business of the owners of mining
property, of resident local merchants, of those who
make or supply mining machinery, just as much as
the business of the miner, to aid in securing good
roads, and the only way to secure them is to put men
in office who will see that sufficient tax is levied to
raise the money and that that money shall be econom-
ically and intelligently spent for the purpose for which
it was assessed.
The Tuolumne county, Cal., supervisors deserve
credit for the effort to better their roads, and appar-
ently if they had more money at their disposal they
would do more than they propose doing. This is a
homely subject; there is nothing technical nor particu-
larly scientific about it, but it is a business proposition
that has been neglected and now is as good a time
as any to act upon the suggestion, in California and
anywhere else that good roads would help in develop-
ing a mining district.
The proposition is so self-evident that it requires
no discussion or argument. It is not business to at-
tempt to put up with such miserable makeshifts as
some of the "roads" found in mining districts, and
the same ordinary rules of business require that what
is taken from the people by taxation should be prop-
erly spent. For instance, in the county of Amador,
California, there is a special road tax of 20 cents on
the $100 ; there is a general road fund beside. In
that county the property is taxed for road purposes
this year to the amount of over $24,000, so that so
far as Amador is concerned the people of that county
are paying for good roads ; but they are not getting
them. That trouble lies largely with wrong system
and mistaken ideas of how the money should be ex-
pended. There is considerable public money annu-
ally fooled away in "repairs" to bad roads, that
leave things no better than they were. The money
is spent ; that is about all that can be said. It were
better to have one mile of good road every year than
have such excuses for roads as exist, even where the
money is supplied for such purposes. There is no
reason why in any mining district there should not be
good roads if modern and intelligent methods are
adopted.
A high average for a good road, including stone
bridges, culverts and other requirements, is $5000 a
mile. In Amador county for its $24,000 could be
built annually five miles of good, permanent road that
would be a good investment for the county ; the gain
would be many times what the five miles cost, and in
a few years it would have what it has not now.
There are few things of greater importance to
this west half of America than this matter of roads.
A horseman draw on a poor road about four times as
much as he can carry on his back; on a good mac-
adamized road he can pull about ten times as much,
on a wooden road twenty-five times as much, and on
a tramway fifty times as much.
All this has been said over and over again, but,
though trite, it deserves iteration and reiteration.
It is an ever-present subject and needs more intelli-
gent attention than it appears to be receiving. Ac-
cepted everywhere as a silent precept, it should be
considered more as an active duty. With the miners
themselves rests the remedy. Public spirit, public
opinion and the plainest dictates of business are with
them — the remedy is organization by the different
county miners' associations and a fixed determina-
tion to see that money is raised for good road work
and spent in such a way as to insure permanent
benefit.
A Good Idea.
Spokane, Wash., wants to hold a mining exposi-
tion next year. The mining men of that city and
section rightly recognize the need of advertising. A
mining exposition is good business for any mining
center. It is not enough that there should be valu-
able mining ground, but it is equally essential that
the fact be widely known. A mining exposition
would be a good thing for Spokane and the North-
west; it would aid in the development of the mineral
resources of that great section. A just display of
ores, of mining machinery and supplies, an exposi-
tion of processes and ore treatment, aud a plain, fair
presentation of general mining resources would be a
grand advertisement for Spokane or for any other
mining center. A mining exposition did much for
Denver; a mining fair held in San Francisco in 1898
had good effects, still felt; the more public attention
can be attracted toward any mining region the more
prosperous it becomes. By means of such exposi-
tions as Spokane projects, a section gets gilt-edge
advertising that it could not get in any other way.
Of course, the sum, intent and object of all such
advertising is to attract the attention of capital
seeking investment. The banks of every large city,
East and West, are crammed with money drawing
from 3% to 5%, in want of something better, in the
opinion of its owners, in which to invest it. In ordi-
nary lines of trade and manufacture competition cuts
so into profits that the margin between loss and gain
is slight. Investors realize that causes unforeseen
and uncontrollable may turn a likely enterprise into
disaster. Some of them, too, are inclined to realize
that a rightly managed mining investment in a good
district stands better chance for profit than in en-
terprises where ordinary trade rules prevail, and
they are inclined to put money into a business in the
product of which no competition exists. Of such
business gold mining is the only example.
It would be a good thing for San Francisco to
have an exposition of that kind. California has
yielded an annual average of $26,000,000 in gold
alone for over fifty years, and in many parts of the
Eastern States and Europe, where the subject is
given any attention at all, the impression prevails
that California mines are worked out. That is only
natural, for it is impossible for any one not knowing
differently to imagine how any section of the universe
could continue to yield gold profitably for so long a
period of time. Of course, Californians know that
what has been mined bears the same relation to what
remains to be got out that the index of a volume does
to the volume itself. Colorado understands the art
of advertising and is profiting by it; Spokane, Baker
City, Rossland and other enterprising points feel the
need of the increased impetus consequent upon such
enterprise and commendable endeavor.

Records of experience in mining and milling are
always of value and their recital would contribute to the
common stock of knowledge. Their receipt would be of
service to this paper and the mining industry in general,
and our readers are courteously solicited to furnish such
notes whenever agreeable and convenient.
Liquid chlorine is chlorine gas compressed to liquid
by a pressure of 200 pounds. One drum of liquid
chlorine weighs 300 pounds, holds 115 pounds liquid
chlorine and takes the place of 972 pounds manganese,
1080 pounds salt and 2160 pounds sulphuric acid. A
drum is 10 inches diameter and 5 feet long.
A motor-generator is a transforming device con-
sisting of two machines ; a motor and a generator
mechanically connected together. A dynamotor is a
transforming device containing both motor and gener-
ator action in one metallic field, with two armatures or
with an armature having two separate windings.
Ore carrying 50% lead and fifty ounces silver per ton
would be "high grade" as a smelting ore; with fifty
ounces silver and no lead it would be considered "low
grade " for either smelting or amalgamating. Ore car-
rying 100 ounces silver would be high grade, considered
as an amalgamating ore, and low grade viewed as smelt-
ing ore.
Palladium is obtained chiefly from a gold ore found
in Brazil. The ordinary process of producing it from
the ore is, after addition of silver, to fuse, then treat
with nitric acid, the silver and palladium dissolving, the
gold remaining undissolved. The silver precipitates as
chloride; the palladium as a cyanide; the latter being
ignited decomposes, leaving palladium.
A variety of antidotes are proposed in the case of
swallowing corrosive sublimate. The best, in every
way, is considered to be the immediate swallowing of
the white of eggs. The white of one egg will neutralize
four grains corrosive sublimate in the human stomach.
"Concentrates " is unable to give any antidote for pois-
oning by inhaling the vapor or fumes of mercury.
A " long-stroke " engine has a stroke about twice
the diameter of the cylinder. A20x48-inch, or a 16x30-ineh,
would be a long-stroke engine. Short-stroke engines
have a cylinder with a diameter as large or larger than
the length of stroke. Slow-speed machinery needs a
slow-speed engine. An engine a little larger than re-
quired is more satisfactory in the long run, or the short
run, than one that is too small for the load laid on It.
In acute cases of lead poisoning sulphate of zinc, to
cause vomiting, should be administered, followed by sul-
phate of magnesia in milk, mixed with white of egg.
In chronic cases of lead poisoning give iodide of potas-
sium three times a day in five-grain doses and sweetened
dilute sulphuric acid in water. At the first indication of
lead poisoning the work should be promptly discontinued
and proper treatment at once adopted. All the soluble
salts of lead are poisonous.
The nickel matte produced by smelting the nickel ores
at Sudbury, Ontario, Canada, contains about 350 pounds
copper and 350 pounds nickel in a ton. The other 1300
pounds is sulphur and iron. The freight on the 2000
pounds to the New York City refinery is $5.50. Last year
the Canadian Copper Co. (the owners) shipped 18,000
tons matte to New York City. Nickel ore or matte
comes into the United States duty free. The refined
metal pays a duty of $120 per ton.
A gasoline fire is best extinguished with flour, sand
or earth in tho order named ; water should not be used.
If the gasoline be confined in small space, ammonia will
smother it. Some users of gasoline find it well to hang a
bottle containing about a gallon of ammonia from the top
of the tank or room containing the gasoline, by a string
or fusible link, so that if the gasoline takes fire the bot-
tle will fall and be broken, releasing the ammonia and
promptly putting out the burning gasoline.
The largest gas engines in the world are using blast
furnace gas for fuel. At the Duedlinger Iron Works,
Luxemburg, are two 1000 H. P. gas engines and one 500
H. P. gas engine in which blast furnace gas is utilized.
The largest single cylinder gas engine is in operation in
Belgium. The cylinder is 51.1x54.1 inches. The Westing-
house works at Pittsburg build the biggest gas engines
in this country— 650 H. P. The Union Gas Engine Co. of
San Francisco has built a 300 H. P. gas engine.
Telegraph poles can be prevented from rotting in
the ground by surrounding the portion of the pole in the
ground with an earthenware pipe, similar to a small
drain pipe, the end of the pipe coming just above
the surrounding soil. Into the space between the
pole and the pipe is placed a mixture of sand and
resin. The resin is melted and poured into the
pipe in that condition. When it solidifies the sand and
resin form a watertight preventive against the butt of
the pole rotting.
Calculations on the subject made some time ago by
F. W. Dean of the American Society of Mechanical En-
gineers, indicate that since 1870 the cost of steam power
has been reduced from 30% to 40%. He attributes 17%
of this improvement to higher steam pressure and ratios
of expansion, multiple-cylinder engines, steam jacketing
and drying or superheating the steam ; 5% to the use of
vertical engines ; 7% to improved boilers ; 7% to econo-
mizers heating the feed water, and 2% to improved
grates. The weight of steam used per horse power per
hour has fallen from 20 pounds to 12.5 pounds. He finds
the compound engine the usual, and on tho whole most
successful, form of engine.
Bitumen is any unsaturated hydrocarbon mixture of
mineral occurrence, whether solid, liquid or gaseous.
Bitumens, from natural gas to asphaltum, include com-
pounds and mixtures of compounds belonging to all the
known series of hydrocarbons. They may be classed as
follows: Solid — asphaltum; semi-fluid— maltha ; fluid —
petroleum ; volatile — naphtha ; gaseous — natural gas.
Some of these fluid varieties of bitumen pass by insens-
ible degrees and by natural causes into maltha, which is
a semi-fluid viscous form of bitumen, known as mineral
tar and just as clearly to be distinguished in consistence
from petroleum as common tar is to be distinguished
from olive oil. The change by which California petro-
leum is converted into maltha is due to two causes, evap-
oration and indirect oxidation.
Smelter treatment charge on copper ores varies with
the nature of the gangue; minimum treatment charge
would be about $6 per ton, maximum about $9. Copper
in ore is paid for at a price based on the New York daily
quotations for casting copper, less 6 cents per pound.
"Dry assay "is the net assay, less an arbitrary reduc-
tion of 1.3% which is common to the trade. Nine and
five-eighths cents per pound would be equivalent to $1.92
per unit, or for each per cent of copper in the ore. An
ore with a favorable gangue, containing a little in excess
of 3%, would pay the cost of treatment, and anything in
excess of 3% would be in the nature of profit after deduc-
tion of charges for mining, transportation, etc. If the
ore contains precious metals, these are ordinarily allowed
for on the basis of 90% of the value at current metal
quotations.
Secretary Bliss of the Interior Department writes
regarding the $500 expenditure required upon mining
claims, saying that "while an expenditure of $100 in labor
or improvements admits the claimant to occupancy for
one year, $500 is required for continued occupancy and
enjoyment. While several claims in common may be
embraced in the same application for patent survey and
notice, a single expenditure of $500 will suffice for but a
single claim. Whatever constitutes a proper annual ex-
penditure under Section 2324 may unquestionably be
treated as part of the greater expenditure exacted by
Section 2325, and since the former is deemed to have
been made upon each of several claims held in common
when it is made upon any one of them for the benefit of
all, so under Section 2325 the expenditure will be deemed
to have been made upon each of several claims held in
common, and included in one application for patent when
it is made upon any one of them for the benefit of all;
but the expenditure of money must equal in value that
which would be required on all of the claims if they were
separate or independent."
All poisons are traced to the circulation, and it is
observed that death is the result ; but there is no satis-
factory explanation of the fatal effects or how the poison
operates. The blood seems to be so changed by the
poison as to render it unfit to perform its proper func-
tions ; but neither chemistry nor physiology throws any
light upon the changes produced by any poison in the
blood or the vital organs. It has been clearly shown
that no substance acts as a poison until it has been ab-
sorbed and passed through the arterial capillary system.
The sooner the poison reaches the blood the more rap-
idly does it act, and it depends not so much upon the
quantity as the amount absorbed in a given time. The
time for this absorption, under favorable circumstances,
is only a few seconds. The fatal effects are produced
when the absorption takes place more rapidly than the
elimination. The fatal proportion of poison present in
the blood at any one time is infinitesimally small (one-
sixteenth grain of strychnine has caused death in four
hours). The blood is about one-thirteenth of the body
by weight, and the proportion of the poison by weight
compared with the blood would be less than one part in
one million. The poison of a cobra is in even smaller
proportion; yet the blood, urine, saliva or milk of an ani-
mal poisoned by a cobra, when injected into the blood of
another animal, will produce death.
The cane of A. Walrath vs. the Champion G. M. Co.
was reported at great length and fully illustrated herein
at the time. The suit was from Nevada Co., Cal., and
was brought for an injunction and $300,000 damages.
End lines and extralateral rights were involved. It was
claimed by the plaintiff that the Champion had gone un-
der the surface of the Providence to some extent. The
case was tried in the United States Court of this circuit,
which gave judgment for the defendant. An appeal was
taken to the United States Circuit Court of Appeals with
like result, and finally the United States Supreme Court,
made these decisions final. In the judgment thus upheld
it was decreed that the patent to the Providence mine
was confined to the Providence lode and to the surface
ground as surveyed and marked In the diagram filed in
the Land Office. The Act of 1872, in granting all other
veins that were within the surface lines of previous loca-
tions; did not create any new lines for such other veins
nor invest the court with any authority to make new
lines for such other veins. When the end lines of a min-
ing location are once fixed they bound the extralateral
rights to all of the lodes that are thereafter found within
the surface location. It necessarily followed that the end
lines of the Providence survey must be considered by the
court as the end lines of any and all lodes or veins which
lie inside of such surface lines.

" How to Make Gold Dredging Pay."
In the current number of Cassier's Magazine is an
article with the above title, written by A. W. Rob-
inson.
A great deal has appeared in this paper during
the last four years on this subject, chiefly original
contributions from experienced men, and those
articles have formed the base of much that has been
reproduced elsewhere concerning this form of secur-
ing gold.
Mr. Robinson's article is not a strictly technical
one, and partakes more of the nature of an essay
than a specific exposition of the subject, but contains
some salient points that, even though said before, de-
serve repetition. In a general way the article is of
considerable value from the standpoint of a civil and
mechanical engineer. Mr. Robinson says:
Dredging for gold seems at first sight to be a
simple proposition, and yet the numerous failures
that have occurred make it necessary to exercise
caution and to examine carefully the causes of failure,
as well as to study the elements of success. If prop-
erly conducted, it is one of the safest forms of min-
ing, for the reason that the ground can be examined,
tested and the probabilities determined beforehand
with reasonable accuracj'. It then becomes analogous
to manufacturing, with the ground as the raw ma-
terial and the gold as the product. To attain suc-
cess in manufacturing, a man must be master of his
business, must have an ample supply of raw material
and must be able to sell at a proper advance over
cost of production. In other words, there must be
good men, good material and good markets, and this
may be all summed up in two words — good manage-
ment. As good management is essential to success
in ordinary business affairs, so is it in the business of
dredging for gold.
There is this advantage over other forms of manu-
facturing, in that the product is of uniform fixed
value, and always marketable without expense of
selling. Every ounce of gold won is that much money
to its owner and a permanent addition to the wealth
of the world. Gold dredging is, however, analogous
to manufacturing in that the cost of production must
be less than the value of the product. Given good
management, therefore, to begin with, the two
cardinal points to be determined are, first, the value
and extent of the ground and, second, the cost of
working it. The success of the whole enterprise de-
pends on the correct determination of these two
questions.
As to the first point, namely, the value and extent
of the ground, a thorough examination should be
made by a person possessing the necessary ability
and experience, and one who is able to draw sound
conclusions from his observations. This is not work
for a young college graduate, nor yet for the so-
called practical miner, although both may render ef-
ficient help. Still less is it the business of men in
other walks of life, who, thirsting for riches, turn to
gold mining, expecting an immediate fortune. His
opinion will be safest who has had not only the wide
experience in all lines connected with his work, but
who has likewise the honesty of purpose and sound-
ness of judgment to avoid deceiving himself or his
clients, and who can determine whether or not the
proposition has in it the elements of financial
success.
Many men whose opinions are trustworthy on other
subjects are entirely unable to form a sane or just
conclusion on matters connected with gold. Many, if
not most, men also are inclined to put a better face
on the question than usually exists, and the sight of
a few yellow colors leads them at once to figure out a
bonanza. If investors would only bring to bear on
gold mining the same prudence and business sense
which is necessary in any other business, it would
greatly reduce the number of failures. The same
care should be exercised in preparing a full state-
ment of all facts and figures bearing on the case, as
in any carefully thought-out manufacturing enter-
prise. How often do we see the opinions of cheap
and incompetent men accepted instead of carefully
ascertained facts.
The business of legitimate mining and dredging for
gold has suffered much from the evil reputation occa-
sioned by the failure of many schemes that ought
never to have been entered upon. Had a competent
engineer been consulted, many of these enterprises
would never have been begun, or at least would have
been carried on in a very different manner. The in-
vestor has to guard against two classes of evil ad-
vice. One is that of the professional swindler who
' promotes ' the property for the sole purpose of
transmitting the funds of the subscribers into his own
pocket, and the other is the well-meaning man who
perhaps has a fairly good thing if properly worked,
but who has more self-confidence than experience and
skill.
The ground should be surveyed — if not accurately,
at least approximately — and a map prepared on
which may be recorded the positions of the test pits,
the area available and the extent of the ground
worked over each season. Test pits should be sunk
at sufficiently frequent intervals to place the nature
of the ground beyond conjecture. The examination
should show the full depth of the gravel, the nature
of the bedrock, if any, and the distribution of the
values, whether they are greatest at the surface, in
layers or on the bottom. Values are never uniformly
distributed, and nothing is more deceptive than a glib
statement of so much per cubic yard. It requires
the most careful judgment to arrive at a fair average
value which will represent the whole.
The nature of the material should also be ascer-
tained, and this not only on the surface. The sizes
and percentages of the gravel, from coarsest to finest,
should be measured. This is necessary to determine
the character of screens to be used, or whether any
at all are necessary. The action of the gravel while
being washed or sluiced should be experimentally de-
termined. Some gravels wash very freely; others,
again, are of a clayey or sticky nature, which renders
them very difficult to wash. Such gravel requires
very careful treatment in order to avoid loss of gold.
Other deposits are of a very hard or cemented' na-
ture, often with large boulders, which increase the
difficulty of working, and, if not fully provided for,
failure will ensue.
The condition of water supply is most important.
Water is essential to the recovery of gold, and its
presence in suitable quantities is a great desideratum.
In dredging beds of rivers, the depth, speed of cur-
rent, fluctuations of level, extent and duration of
floods must all be closely observed and their bearing
on the proposed enterprise considered. In many
rivers the richest pay is found in the 'bars,' which
are shoals or deposits of gravel brought down by the
current and formed by slack water. These are fre-
quently dry at low water, and the dredger must,
therefore, be able to cut its own flotation into a dry
bank.
Gold dredging is not necessarily confined to river
beds or natural water courses. Any deposit may be
worked with a floating dredge in which the water
can be impounded, and a small stream let into the
pond in which the dredger is situated, sufficient to
supply evaporation and leakage, and to keep the
pond clean enough for washing purposes. The same
water can be used over and over again in this way,
but the dredger must be specially adapted to each
case. A dredger which will be suitable for a river
channel may not do the work at all in an enclosed
piece of ground, and vice versa.
The disposition of tailings is a subject which must
be carefully studied. Unless the dredger can get rid
of all material passed through without choking or
piling up in such a manner as to interrupt its work,
it is liable to be stopped, and the entire enterprise
brought to a standstill until the difficulty can be
remedied. The configuration of the ground, the
character of the material, the depth of the water
and the height of ground worked above water all
enter into the question and should be carefully de-
termined.
As to the gold itself, the question is threefold.
There are to be considered, first, the character of
the gold; second, its value per cubic yard of material
handled; third, the best method of saving it. On the
satisfactory determination of these points the whole
success of the enterprise depends, and here long ex-
perience and sound judgment are absolutely neces-
sary. The gold may be fine or coarse, of all degrees,
and may be easy to save or difficult to save, and the
most effective method of saving it depends upon its
character. There is no 'new discovery' for gold
saving. All known methods depend on one thing for
their successful action, namely, the great specific
gravity of the gold as compared with gravel. Their
separation can be effected only by washing with
water, aided sometimes by amalgamation, but the
methods of washing are subject to wide variation.
There are the two extremes of heavy hydraulic sluic-
ing with large volumes of water, carrying down
boulders and everything before it, and the thin film
of fine concentrates, requiring delicate adjustment
for saving fine gold.
As to the value per cubic yard, this is perhaps the
most difficult point on which to obtain a reliable esti-
mate. The difficulty is not so much that it can not
be ascertained, but that men involuntarily exaggerate
the findings, and there is an extraordinary inclination
to take the best and richest spots as an indication of
the whole. The only safe way to do is to wash out a
considerable quantity for each test, say not less than
a cubic yard, taking care that all the material —
boulders and all — is included in the measurement, and
carefully weigh the result. A sufficient number of
these tests, carefully made, will indicate the average
value.
In many places in the United States, Chinamen or
tramp miners can be found working along banks of
streams or on river bars with rocker and pan.
Wherever these remain any length of time there is
sure to be gold in paying quantities. It may, how-
ever, exist only on the surface, for these men can not
work deep.
After all the foregoing points have been settled,
there remains the final question — What will it cost to
work the property ? This is a broad question, and
the answer to it is to be found only by subdividing it
into all the points which affect the cost, and making
a careful analysis and estimate. These points include
(1) transportation, (2) cost of living and wages, (3)
cost of fuel, (4) cost of lumber and other material of
construction, (5) water supply, (6) character of ma-
terial, (7) depth of working and (8) study of any spe-
cial difficulties that may be presented. It is im-
possible to give any data as to these various points
or the general conclusions that may be drawn from
them. Each locality will have its own character-
istics which may be more or less favorable. The
dredger itself will be designed to suit the conditions
as they exist and its output and operating expenses
estimated. The actual output should not be esti-
mated to be more than half the theoretical, and a
liberal allowance should be made for contingencies
and repairs. Under favorable conditions dredging
can be done for 4 or 5 cents per cubic yard, or even
less, and under difficult and costly conditions the cost
may rise to 20 or 30 cents, or even more.
The dredger itself is a most important factor in
the cost of operating, but it is not proposed here to
go into the mechanical detail of its construction, as
that is a large subject by itself. It is sufficient to
say that for all ordinary conditions the elevator or
ladder type of dredger has become recognized as the
standard. It is usually composed of the following ele-
ments: (1) The dredging machine proper, (2) a re-
volving screen in which the material is washed and
the coarse stones are removed, (3) a centrifugal
pump for supplying water to the screen, (4) gold-
saving tables or sluices and (5) apparatus for dispos-
ing of tailings.
All these elements are suitably combined upon a
hull with boilers, engines and accessories. It is ab-
solutely essential that the dredger be designed and
built by those experienced in such work, and that
every detail should be of ample strength and suitable
for the purpose. A great many dredgers have been
built; and while they are by no means finally perfect,
experience has developed their construction along
certain fines which have been shown to be the best.
This experience has cost large sums of money, and
he would be foolish indeed who would undertake to
build a dredger out of his own unaided genius without
a thorough knowledge of the work of others in this
line. These dredgers must, as a rule, work in re-
mote places and be operated by ordinary labor. It
is, therefore, of the first importance that they should
be of the simplest possible construction, with every
part of ample strength, and not liable to get out of
order. The earlier dredgers were very deficient in
this respect, and, if breakdowns and repairs are fre-
quent, the profits may be quickly converted into
losses.
When a dredger is standing still from breakdown
there is a four-fold loss going on: (1) Interest on in-
vestment, (2) cost of replacing the broken part, (3)
expenses of crew and administration and (4) loss of
gold that would be gained if running. The first cost
of the part that failed is but a trifle to the other
losses, and the first cost, therefore, of the entire
dredger is of slight importance, provided it is of
proper design, well built and capable of working con-
tinuously without breaking down. Some repairs
there must inevitably be, owing to the severity of the
work and the wear and tear due to handling the ma-
terial; but a distinction must be made between such
natural wear and parts structurally weak which may
fail without warning. In a good design not only will
all parts subject to natural wear be capable of ready
renewal, but all important parts subject to strain
will be of the strongest design and have a large
factor of safety.
Suppose a dredger is earning $400 per day, and is
delayed thirty days through the breakage of some
part not readily replaced. There are $12,000 lost,
without counting interest, or cost of repairs, or
wages. A fraction of that amount, put into better
design and better material at the outset, would have
been the best possible investment. Steel castings
can now be obtained at about twice the cost of iron
castings, and should be used wherever possible in-
stead of iron, regardless of the extra cost. Some
dredging machines on the market are but cheap
affairs, made to sell, not to last, and no care or
trouble is taken to adapt them to their work. In-
deed, the builders of them rarely have that experi-
ence in operating and maintaining them that is neces-
sary. A cheap dredger is necessarily a poor one,
for the requisite strength and quality can not be ob-
tained without cost; but, on the other hand, an ex-
pensive dredger is not necessarily a good one.
When the cost of fuel is high, special attention
should be paid to economy of steam in the design of
the dredger, such as using compound condensing en-
gines and efficient boilers. If fuel be cheap and
abundant and skilled labor high, simple high-pressure
engines will answer every purpose. Water power
may also be utilized to good advantage for driving a
dredger or series of dredgers, employing electric
transmission. The perfection of modern electrical
apparatus for the generation and transmission of
power is such that it is, on the whole, quite as reli-
able as steam. So far from being more complicated,
it is, in fact, simpler, for the substitution of simple
electric motors for boilers, pipes, pumps, engines and
valves involves fewer parts and less liability to de-
rangement.
In addition to all the technical and commercial ele-
ments which have been touched upon, the financial
strength of the company intending to operate is of
not less importance. It would be useless here to
make recommendations as to amount of capital re-
quired, as circumstances are widely different. The
funds should, however, be available before beginning,
and should be sufficient to meet and overcome any

reasonable obstacle or difficulty that may arise.
That must be left to the judgment of the business
man and the engineer in taking up each special case.
Enough has been said to point out the way and to
indicate the lines on which this class of work may be
successfully carried on. There are few more promis-
ing or more profitable fields of work when carefully
administered, and the ground available has as yet
scarcely been touched. Unfortunately in many cases
large sums of money have been squandered without
result because of the lack of knowledge and experi-
ence to provide for all the points essential to success.
All of these failures can be traced to perfectly pre-
ventable causes, and, when rightly judged, they serve
as landmarks to point the safe way.

The Selection of a Working Process.*
By Chakles M. Passett.
A few years since a professor in one of the German
universities said to an American mining engineer,
who was telling the professor of gold being found in
galena, " It cannot exist." He was an old man and
I has since died, leaving an undying name on account
of his discoveries in the science of metallurgy ; but
with all his learning and lifelong research he could
not believe possible the existence of gold in a com-
bination now familiar to everyone. No one thought
it possible that precious metal could live in sandstone
until Silver Reef was discovered ; no one believed
gold could exist in porphyry until Cripple Creek was
found ; and now that we know gold is being profitably
extracted from such improbable materials as mica
schist, hornblende, and granite, the conservative
man will be careful not to say that it cannot exist in
basalt, lava, or any other rock, and we may all have

distinction of lying in two different countries — the
United States and Mexico. It is on the extreme south-
ern edge of the frontier, in Pima county, Ariz. , part
of the " Gadsden Purchase " in 1853, and from a min-
ing point of view is an important place, being the
gateway through which passes considerable of the
traffic between the mining regions of Arizona and
the State of Sonora, Mexico. Through the town runs
" the international line," as depicted in the picture
on the front page, for which we are indebted to the

to fall back upon the unscientific but extremely safe
old California dictum: "Gold is where you find it. "
Starting then from this point, and after having
found it, the question arises: How shall we get the
metal from the rock and put it into shape for utiliza-
tion for minting or the arts. The great bulk of gold
produced to-day is obtained by the use of stamp
mills and amalgamation, in many instances supple-
mented by various processes for extracting the residue
of precious metal from the tailings. This is the cheap-
est method of extraction known and is limited in its
use only by the condition of the gold as to its being
free or combined with, or entangled in, base com-
binations. No ore is absolutely free milling, nor is
an}' gold ore entirely base; every ore containing
notable quantities of gold will yield at least a part of
its value to mercury, and this process should always,
in my opinion, receive the first consideration in settling
j the problem of a working method. If you can obtain
' half the value on the plates it is reasonably certain
| that enough more can be obtained by subsequent
treatment on the ground, either by concentration,
cyanidization, chlorination or pan amalgamation, to
render this process the most available.
Smelting is the oldest, the best known and the
most generally applicable method of ore reduction
now practiced. If ores could be smelted as cheaply
as they can be milled, it is safe to say that this would
be practically the only process in use in the world
to-day. It is essentially a chemical process — a break-
ing up and reuniting of the molecules of the ores,
fuels and fluxes, by the aid of heat — and distinct from
the essentially mechanical process of milling. It is
interesting to the chemist to note that while a com-
plete analysis is absolutely necessary to determine the
proper method of fluxing a smelting ore, it is of little
or no use when applied to a milling or other physical
process. The adaptability of an ore for treatment
by a chemical process is determined by its chemical
analysis; for a physical or mechanical process, by
physical tests.
I need not consider the smelting process at length,
as in its relation to the owner of a developing mine it
is simply, on account of its expense, a temporary ex-
pedient or a last resort. Nine-tenths of the smelting
is done at custom works, run independently from any
mine, and, from the very conditions surrounding the
industry, it will continue to be conducted in this man-
ner except in infrequent cases. The cost of smelting
a neutral ore is not great, but when combined with
the usual extra charges on detrimental constituents
and railroad freights, it often amounts to a prohibi-
tion.
Competition and improved processes, however,
have greatly cheapened this process in late years,
and made it possible to ship ore at a profit from
mines heretofore unavailable. Within the past fifteen
years I know of a smelter in Nevada where $24 per
ton was the treatment charge, and they paid only
62}% of the value of the silver and 95% of the gold at
$20 per ounce. How many of you who are now ship-
ping ore could do so under such a tariff as this ?
Matte smelting, and pyritic smelting, in which
process the sulphur in the ore furnishes the greater
part of the fuel, are concentration methods of great
utility and will always be used in remote districts
where transportation charges on the crude ore are
prohibitory, and mechnical concentration inappli-
cable. The cost of a plant is not great, and the cost
of treatment is low if a proper mixture of ores and good
fuel are available; but the very highest skill is de-
manded both in the construction and running of such
works, and owing to the comparative newness of the
process, such skill is not readily available.
Mechanical concentration is often practiced on
smelting ores, and its utilization has brought millions
of wealth into circulation that otherwise would be
still lying idle in low-grade rock. It is a boon to the
miner, saving freight and treatment charges on
waste and detrimental material, making a valuable
and much sought product of an ore which in its crude
state would be hard to treat.
If you have a mine which is in a condition to pro-
duce ore in sufficient quantities to justify the erection
of a mill, the first thing to be done is to obtain a
sample of ore which will represent, in its assay, value
and principal characteristics, the ore that you will
be able to mine. This is the most important and,
perhaps, the most difficult thing to do. It is utterly
foolish to go to the expense of having working tests
made on your ore unless you can produce ore in
sufficient quantity and can take a representative
sample. It seems unnecessary to say this, but the
Pacific coast is dotted with expensive evidence that
these conditions have not been fulfilled. When you
have obtained your sample and assayed it (it should
weigh 100 to 500 pounds), try these processes, begin-
ning with an amalgamation test, and when you have
found a method that seems most available, go back to
it and try it over and over again, varying the condi-
tions in every way you can think of, such as fine and
coarse pulverization, concentration before and after
milling, etc. Experiments made carefully on small
quantities of ore will be found of great use in
determining upon a process, and in many cases will
tell you very closely what can be expected on a large
scale. Send part of your ore to the smelters, and to
any crazy scientist whom you may hear is working pn
a new process. Take time to let them all have a trial
at it, and remember that, as no two ores are alike,
yours may be just the ore that is adapted to some
embryotic method that will treat it successfully. When
they have solved the problem the world sees the
dazzling light of genius in their eyes.
When you are ready to build a mill, get the best
man you can find to design it for you. It is always
economical. Don't buy any piece of machinery be-

and expensive experience, that it is folly to expect

Refining California Petroleum.
In obtaining refined products from native crude oil,
the first step consists of placing the crude oil in
large, hollow, cylindrical stills, enclosed in and sup-
ported by brickwork and suspended over large fur-
naces; heated by liquid fuel above the boiling point,
the vapors rise from the surface of the oil, entering
large iron pipes immersed in water, passing through
these pipes condensed in liquid form and emerging
from the pipe as a distillate.
In this first process of distilling, different sections
of the oil are separated into series. Those that come
off of the still first are lighter in weight and in color,
and have a low boiling point. As the process of dis-
tilling goes on, the boiling point continues to rise,
until it requires several hundred degrees of heat to
lift the vapors out of the still. The products now
obtained are crude distillates, on the one hand, and
the part remaining in the still is refined asphaltum.
With some refiners this is all that is done in the han-
dling of the crude oil, and the sales are made of the
refined asphaltum, and the crude distillates — whose
value is only a little above that of crude oil.
A complete refining plant is equipped with a large
number of tanks, in which these various divisions of
the oil are stored, and taken from them separately,
and, by being excluded from the light and carried
through a process of cleansing by the use of sulphuric
acid, alkali and water, and again put through the
process of distillation for the final separation,
made ready for the particular use to which they are
adapted ; other portions are exposed to the sun and
air and rain and left in the open tanks for some time
to effect the curing and ageing process, which ren-
ders them more susceptible to the action of the
acids, alkali and water in the purifying process.
These oils are finally finished by filtration so as to re-
move from them anything of a foreign nature that is
not an oil perfect in form and color.
The lighter oils are those that are treated in such
a manner as to exclude them from the light, and are
calculated for use as illuminants, or as oil for power
use in generating power in distillate engines. While
the article supplied by the refineries for use as gen-
erative power is termed distillate, it is, in fact, a re-
fined oil, and as much pains and skill is required to
produce a satisfactory gas engine distillate as is
necessary to produce a satisfactory burning oil for
domestic use.
The other class of oils is intended for lubricating,
and the process of preparing them for market re-
quires considerable time and a large number of tanks,
as the oils have to be changed from place to place as
they pass through the various cleansing processes.
When finished, these oils are nearly odorless, and
have an appearance far removed from that of the
crude oil.
When crude oil is divided up into its various com-
ponents and hydrocarbons, the colors in the finished
oil show all the colors of the solar spectrum, starting
with the white and ending with black.
By the duplex system of telegraphy two operators
can transmit simultaneously in opposite directions.
This is attained by winding the receiving relays with
two coils of wire in opposite directions, one winding
being connected to the line and the other to a set of
resistance coils and condensers which are so adjusted
that the electrical length and static capacity are the
same as the real line. The home power divides
equally, half passing around the core in one direction
to the real line, and half in the opposite direction to
the artificial line, the result being that the core is
not magnetized by it, and it is not susceptible to the
home power. As the power coming over the line
from the distant station only passes through one of
the coils, and there is none coming in from the arti-
ficial line to counteract it, the core is affected by any
change in power at the distant station. The receiver
is a polarized relay whose armature closes the
sounder when moved in one direction, and opens it
when moved in the other. The transmitter is an in-
strument worked by an ordinary telegraph key and
local circuit. It is so arranged that when the key
is depressed the negative pole is connected to the
line, and when positive the key is opened.
Concerning the article in the issue of the 13th inst.,
on the formation of lode matter, it may in general be
said that whatever be the facts in any particular case
regarding the present deposition of minerals, it is
manifest that the chemical changes of the earth are
constant though varying in degree, and that though
at this time the formation of new mineral deposits is
perhaps less active and confined to fewer localities
than has been the case at other periods of time, they
are still forming. It is, however, probable that these
formations are more largely observed in old mines
which are being reopened by unwatering and that the
mineral simply accumulates locally. One instance is
that of a mine in the Joplin, Mo. , lead belt, which laid
idle for some years, and, upon being unwatered about
two years ago, presented some interesting examples
of secondary accretion. Large cubes of galena had
during the period of the mine's abandonment been
eaten away, and tiny cubes of the same material had
formed upon the surface of them. There are also,
doubtless, instances where minerals are dissolved at
one point and redeposited elsewhere, more or less re-
mote ; but, as a whole, that is a period of rest, and it is
doubtful if more than isolated cases may be cited
where minerals from which the ores of the metals are
obtained are depositing with any degree of even geo-
logical activity. The epoch in which the Comstock
and other large mineral deposits were formed is re-
ferable to a remote period of time with which the
present period of deposition bears but poor compari-
Enclosed Electric Motor.
Herewith appears an illustration of a bi-polar type
of enclosed motor, manufactured both as a motor di-
rectly connected to a propeller fan and as an inde-
pendent machine. For the former purpose it is used
on all sizes of fans up to and including the 54-inch.
For larger sizes the four and eight pole types are
employed. As will be observed, the motor is entirely
enclosed, and thus protected from dust. A low tem-
perature rise can be maintained without greatly in-
creasing the size and weight above that of the or-
dinary open type. The machine is capable of con-
tinuous operation for ten hours, with a maximum
temperature rise not exceeding 60° F. Yokes ex-
tending out from the field ring support the armature
shaft. The end casings are independent, and can be
instantly removed to give access to the entire in-
terior. The bearings and brushes can be reached by
removing the caps in the center of the casings. The
brushes are of hard carbon, in holders of a modified
reaction type, which allows of easy adjustment when
it becomes necessary to reverse the direction of rota-
tion of the motor. The bearings are self-oiling and
self-aligning, and are fitted with composition sleeves,
removable from the outer ends of the boxes. These
motors, in sizes from i to 5 H. P., are built by the
B. F. Sturtevant Co., Boston, Mass.
The Cazo Reduction Process.
The treatment in reducing silver ores, known as
the Cazo process, was invented by A. Barba in Peru,
and from there introduced into Spanish possessions
in America, including Mexico. It is a simple
amalgamation process considered adapted for
native silver, chlorides, bromides, and iodides of sil-
ver, which are treated in hot solutions by this
method. The Cazo kettle or boiler consists of a
wooden tub with a bottom made of a spherical seg-
ment of copper about 2 feet in diameter. The wooden
board er tub is jointed to it by means of copper
rivets. The Cazo or boiler is placed on a furnace
and contains from 200 to 300 pounds of finely pulver-
ized mineral, each charged together with from J to
TV of salt and water sufficient to form a liquid paste.
The man in charge of the operation keeps a slow fire
to produce a low boiling temperature, and adds from
time to time small quantities of quicksilver. The chlo-
rides and bromides of silver are dissolved in the solu-
tion of salt and are decomposed by the copper of the
kettle. The reduced silver amalgamates itself with
the mercury. The object of adding the mercury only
a little at a time is in order that the chlorides and
bromides of silver be reduced by the copper and not
by an excess of mercury. The man in charge of the
operation stirs the mass constantly by means of a
ladle. From time to time a sample of the amalgam
is taken from the bottom of the kettle, and when it
has the appearance of lead filings the operation is
completed. This takes place generally in about six
hours. Then the charge is taken out and a new one
put in its place, and when a sufficient number are ob-
tained they are put together, the amalgam washed
and strained, and the quicksilver distilled to obtain
the silver. The loss in quicksilver is variously esti-
mated from 2% or 3% to a weight equal to that of the
silver recovered.
Sometimes this method has been employed with
minerals containing silver sulphurets and sulphide,
but then the minerals have to be previously roasted
with salt. The roasting must be carried on suffi-
ciently long to decompose and volatilize the greater
parts of salts of iron and copper, otherwise the loss
of mercury would be excessive. The practice in
Mexico generally is to use two parts of mercury for
each part of silver, but experiments carried out on a
large scale by Becquerel Bros, and M. Dupont shows
that by using four or five times as much mercury per
unit of silver a greater amount of silver is recovered.
The relative value of silver and the loss of mercury
necessary to obtain a certain increase regulates the
proportion of the two metals.
According to M. Dupont the amalgam obtained by
the Mexican process has for its formula Hg2 Ag,
whereas by increasing the use of quicksilver he ob-
tains amalgams with a formula of Hg* Ag. If a
great excess of mercury is used it will combine with
the copper of the Cazo and will be lost for amalgama-
tion with the silver, whereas a small excess is not det-
rimental, because the reduced silver will keep the
walls of the copper kettle clean. At ail events the
quicksilver must be added in small doses.
Regarding the quantity of salt to be used in this
process the solution of salt employed should have a
density of from 15° to 20° Beaume. When the pro-
per minerals are used in this process the silver ob-
tained is 995 fine. M. Dupont has applied this process
to nearly every variety of silver ores by preliminary
roasting, Becquerel Bros, have used it in the treat-
ment of silver galenas.
The Fatigue of Metals.
In discussing crystallization of iron and steel under
shocks and vibrations, one important factor which
destroys the best metal when subjected to long-con-
tinued shocks is ignored or passed over, while the
secondary effect of this cause, the granular appear-
ance of the fracture, is given attention. The factor
thus forgotten is the ability of a beam, an axle, or a
stamp stem to conduct vibrations speedily away from
the point of impact, and distribute the motions thus
caused uniformly and uninterruptedly from particle
to particle through the mass of the metal during the
longest possible period of time without fatiguing the
metal. This immediately raises the question, "What
is fatigue of metal?" a question more easily asked
than answered. One must be a little arbitrary in
conception of the term and nature of the fatigue of a
metal that he may have something tangible to
start on.
We all know, speak and reason about the conduc-
tivity of a metal, by which is understood its property
to transmit heat or electricity through its mass with
greater or less facility, according to its nature,
whether it be a good or bad conductor. Given a
metal known to be a good conductor of heat, for in-
stance, we know that, other things being equal, its
conductivity can be impaired in various ways — by
flaws, impurities, hollow spaces, irregularities in out-
lines, want of uniform density, etc. The heat imping
ing against the metal not being conducted away read-
ily on account of the obstacle encountered in the
shape of any of the defects mentioned, it follows that
at or near the point of contact of metal with the
fire the metal becomes hotter than it would if con-
ductivity were unimpaired. The greater the impair-
ment the greater the heat, and the more frequently
the heating is repeated the more speedy will be the
failure of the metal thus abused.
On the other hand, supposing a metal to be an
ideal conductor, it stands to reason that in the course
of time a period will ensue where the particles are
not as responsive, as ready for work as they used to
be ; that is, the metal becomes worn out, and will
readily break at the weakest point.
In speaking of conductivity, one fancies in his mind
the heat striking first the extreme outer layers or
layer of a metal, and, by virtue of the close contact
of its particles, traveling from particle to particle
until the end or other side of the metal is reached.
As a matter of fact, one can feel or in other ways
observe this movement of heat along a bar of metal.
Motion imparted to a structure, or part of a struc-
ture, will be and is transmitted from particle to par-
ticle in a similar way as heat or electricity. That is
to say, motion imparted to a piece of metal at the
point of contact will cause vibration of the molecules,
but the vibrations thus set up must travel along the
various points of contact of the crystals or fibers,
and hence is subjected during its passage from one
end of the metal to the other to the same influences
as is heat or electricity.
If there are impurities, flaws, irregularities of
structure, unequal density, motion will be retarded,
deflected or arrested, just as a cracked bell will give

by striking the bell are arrested by the crack in
their onward movement.
It is also reasonable to assume that in the case of
inequalities in the metal of one kind or another cer-
tain portions of the structure — beam, axles, stamp
stems, etc. — are more severely affected by the mo-
tion than the rest of the metal, because certain por-
tions are less conductivo or less able to carry the
vibrations along. One can imagine this to take place
in a manner analogous to a weight unequally distrib-
uted. When equally distributed a body may be amply
able to carry it, but will break down if the weight is
put on one point only.
Likewise, if the force of impact remains the same
for a partly defective metal as for a perfectly sound
one, the sound portions in the defective metal must
necessarily be taxed more than if the whole of the
metal was sound. But even if perfect in every par-
ticle, it is natural that vibrations many times re-
peated must eventually produce a deteriorating
effect, since there is nothing of artificial creation
which is indestructible. When that point of deterio-
ration in a piece of metal subjected to repeated
vibrations is reached where, even in the soundest
piece of metal, the motion wave is not carried along
as freely from particle to particle as originally, then
one may conceive the metal to be what is called
fatigued — tired, in a state of weariness, inability to
respond with its inherent strength. What the actual
condition and nature of a piece of metal is when it is
fatigued probably no metallurgist is able to describe
or knows. We may, however, assume that fracture
of metal in ordinary service must be preceded by an
initial separation of the particles at their points of
contact, and this initial separation must be preceded
likewise by a loosening of the particles, a relaxation
of the force of cohesion.

Machine Mine Rock Drills on the
Pacific Coast.
NUMBER II.
Written for the Mining and Scientific Press
by A. E. Chodzko.
In concluding this review of the rock drills used on
the Pacific coast, a few general considerations con-
cerning the economical side of machine work will not
be out of place, assuming, for instance, the case
where a certain length of tunnel or drift is to be
excavated and taking it for granted, which is no
exception, that the men in charge are experienced
miners, i. e., that they place their holes to the best
advantage as regards the ground formation, and con-
sequently that the amount of explosive used is a mini-
mum under the circumstances.
The total cost of the work, besides this element,
will consist, for each rock drill used, of three princi-
pal items, namely:
First — Cost of the compressed air consumed by the
machine, including : (a) cost of motive power ; (b) sup-
plies and maintenance ; (c) attendance.
Second — Wages of miner and helper.
Third — Cost of repairs.
With reference to the cost of compressed air, it is
obviously desirable that each machine should use the
least possible amount of air to do a certain work,
and this result can be attained in two principal ways,
applied singly or in combination, namely: By having
the valve motion arranged so as to avoid unnecessary
cushioning at the usual piston stroke, or, in other
words, so as to deliver as powerful a blow as consist-
ent with the size of the cylinder and the air pressure.
Also by reducing the clearance, which in many rock
drills represents a very high percentage of the total
capacity of the cylinder.
This reduction in the quantity of air consumed by
each machine amounts to saying that either the time
of actual running of the compressor will be reduced, or
else that more rock drills can be operated with the
same compressor.
. The importance of this cost of compressed air may
vary in different places. There are such cases, for
instance, where a mine is using its own system of
water power, and where the compressor is started
and stopped automatically. The running expenses
would then vary but little with the air consumption ;
the supplies item alone would be affected thereby,
and a wasteful type of drills would merely require
the purchase of a larger compressor at the start.
This, however, represents an exception, and in a
majority of cases a reduced air consumption is a
desirable feature of a drill.
Second — Wages of miner and helper. This part of
the cost is in direct proportion to the time, and the
desirability of a machine delivering a powerful blow,
i. e. , drilling in a given time a maximum length of
hole, is evident.
Third — Next comes the cost of repairs, which is
not necessarily in proportion to the time of operation
of the machine. It will be readily understood that,
if it is doing heavier work during fewer hours, the cost
of repairs may be the same or even higher than if the
drill is working more leisurely during a longer time.
Without referring to any specific figures, it may
be noted that should the average cost of repairs per
day equal the amount of wages paid to the men in
charge, seven new machines could be purchased
every year for the money required to keep one of
them in repair, a state of affairs which few miners
would be likely to accept.
It is, therefore, safe to say that, for all possible
reasons, economy in rock drilling means rapidity.
But, passing from general considerations to precise
figures, one instance might be quoted, among others,
with reference to a large mine where an exact ac-
count was kept of the actual cost of drilling, with the
following results, the miner being paid $3 and the
helper $2.50 per day:
Per cent.
Power 23.1
Wages 74.1
Repairs 2.8
Total 100.0
This shows that it is an erroneous, though not un-
common, view to state that the cheapest machine is
the one which costs less to keep in repair. In the
large tunnel enterprises where rock drills were first
used this point had been so well understood that in
many instances they would not even go to the trouble
of repairing a disabled drill ; it was simply thrown
aside and a new one put in its place. It is safe to
say — and the writer can tell it from personal expe-
rience— that the machines were worked for all there
was in them, and when they failed they were really
fit for the scrap pile. To make time at any cost was
the only motto, and, under the circumstances, the
right one. It would probably be carrying things too
far to apply the same process in a mine where a few
rock drills only are in operation ; but the principle
remains the same, namely, that the most economical
machine is the one that will drill the greatest length
of holes in a given time. Power of action and, if pos-
sible, reduced air consumption are, therefore, the
two points to be borne in mind when selecting a ma-
chine drill,

Splicing Wire Rope..
In the issue of Sept. 29 appeared an illustrated
article on "How to Splice a Wire Rope." The mat-
ter is of sufficient interest to warrant further notice.
The annexed is a way recommended by John A.
Roebling's Sons' Co., manufacturers of wire rope,
Trenton, N. J. :
Directions for making a long splice in an endless
running rope of i half inch diameter : Tools required
— One pair of nippers for cutting off ends of strands ;
a pair of pliers to pull through and straighten ends
of strands ; a point to open strands ; a knife for cut-
ting the core and two rope nippers, with sticks to
untwist the rope ; also a wooden mallet.
First — Haul the two ends taut, with block and fall,
until they overlap each other about 20 feet. Next
open the strands of both ends of the rope for a dis-
tance of 10 feet each ; cut off both hemp cores as
closely as possible (see Fig. 1), and then bring the
open bunches of strands face to face, so that the
opposite strands interlock regularly with each
other.
Second — Unlay any strand (a) and follow up with
the strand 1 of the other end, laying it tightly into
the open groove left upon unwinding a, and making
the twist of the strand agree exactly with the lay of
the open groove, until all but 6 inches of 1 are laid in,
and a has become 20 feet long. Next cut off a within

magnitude that is not directly under the domination
of trusts and monopolies. It defies the manipulation
of politicians and is one industry to-day which offers
a fair return for money invested and labor ex-
pended.
Movement of Ground Water.
The amount of water stored in saturated soil —
that is, below the ground water surface — is, in round
numbers, two-fifths of the whole bulk. Usually three-
quarters as much is to be found even in soil above the
plane of saturation, except during dry times in a sur-
face layer 1 to 5 feet thick. Saturated sandstone
may contain as much as 38% in bulk of water, equiva-
lent to immense and deep lakes in widespread and
level-lying areas of sandstone. Even compact mar-
bles and granites contain an appreciable percentage
of water. It is probable that water penetrates the
earth's crust in some degree to a depth of more than
10,000 feet.
Consolidated and deep-lying rocks have, in growing
compact, lost much water. Fine silt deposited in
water contains more than half its bulk of water, but,
on compression by overlying sediment, part of the
water is driven out, either upward, downward or
sidewise. Evidently, vast quantities of water must
so have been expelled from the enormous masses of
rock that now underlie mountain regions, much of
the rocks at present having less than 1% of pore

Splicing Wire Rope.
6 inches of the rope (see Fig. 2), leaving two short
ends, which must be tied temporarily.
Third — Unlay a strand (4) of the opposite end and
follow up with a strand f, laying it into the open
groove, as before, and treat it precisely as in the
first case (see Fig. 3). Next pursue the same course
with b and 2, stopping, however, within 4 feet of the
first set ; next with e and 5 ; also with c, 3 and d, 4.
We now have the strands all laid into each other's
places, with the respective ends passing each other
at points 4 feet apart, as shown in Fig. 4.
Fourth — These ends must now be secured and dis-
posed of, without increasing the size of the rope, in
the following manner : Nipper two rope slings
around the wire rope, say 6 inches on each side of
the crossing point of two strands. Insert a stick
through the loop and twist them in opposite direc-
tions, thus opening the lay of the rope (see Fig. 5).
Now cut out the core for 6 inches on the left, and
stick the end of 1 under a, into the place occupied by
the core. Next cut out the core in the same way on
the right, and stick in the end of a in place of the
core. The ends of the strands must be straightened
before they are stuck in.
Now loosen the rope nipper and let the wire rope
close. Any slight inequality can be taken out by
pounding the rope with a wooden mallet.
Next shift the rope nippers and repeat the opera-
tion at the other five places.
After the rope has run for a day the locality of the
splice can no longer be discovered. There are no
ends turned under or sticking out, as in ordinary
splices, and the rope is not increased in size, nor
appreciably weakened in strength.
The foregoing rules apply only to ropes with hemp
centers. Ropes with wire centers may be spliced in
same manner as hemp ropes by putting in long splice.
space. Such water-bearing sediments, when carried
down several thousand feet, must in higher tempera-
ture expand and drive out water in some direction,
the water flowing much the more readily from its
lessened viscosity at a higher temperature. The
gradual deposition of mineral matter from the sta-
tionary film of water around the grains of a stand-
stone, and the conseqquent absorption of other
mineral matter by the film from neighboring circu-
lating water, and again the deposition of this ab-
sorbed material, until the rock becomes much more
compact and less porous, must occasion the expulsion
of great quantities of water in the case of vast bodies
of rock. The consolidation of 50,000 square miles of
sediment 1000 feet deep, with an original pore space
of 33% reduced to Z%, must require the expulsion of
a sheet of water 50,000 square miles in area and 300
feet deep, and its replacement by solid rock material
— enough material to take the Mississippi river 60,000
years to supply, even with 150,000,000 tons carried
in solution annually to the sea. Such subterranean
movements of water are extremely gradual, lasting
through long periods of time.
Effect of Drouth on Boilers.
Mining is the noblest of industries. From it all
cruelties of competition have been eliminated. In the
wake of the successful miner destitution, despair and
death do not follow — his enrichment does not mean
another's impoverishment. The miner delves into
the earth and brings forth something which adds
to the comfort, happiness and wealth of the world —
he is a producer, and the world stands ready to buy
his product. Gold mining is the only industry of
Some of the causes which contribute to produce
variations in the amount of scale formed in a boiler
in any specified time are often overlooked. The
amount of rainfall during the season has a direct
bearing on the scale formation, though few steam
users would think it possible.
Unusual deposits of scale are generally due to an
increased hardness of the water, when the supply
must be drawn from the lower strata where it has
become impregnated with lime and magnesia. On
the other hand, in seasons of heavy rain the surface
water, which is much softer, is largely used, the pro-
portion of scale being smaller.
From this it can be seen that during a dry season
boilers should be cleaned more frequently, and an in-
spection should be made about twice as often as
before. During a time of abundant rainfall a general
loosening of the incrustation may be expected, and
its lodging over the fire sheet should be guarded
against. — Locomotive.

LAKE COUNTY.
The Chronicle says zinc shipments from
Loadvillo to European points have ceased;
all the product is now diverted to Mineral
Point, Wis., and Iola, Kan. When the
contracts for foreign shipments expired
nono of them were renewed; agents for the
Mineral Point and Iola plants were ready
to take all the zinc that Leadville could
produce. The price is a little better than
the foreign brokers were paying. The
daily total zinc output at the present timo
is about 200 tons. The Iola works make a
spelter of the product, but at Mineral
Point a considerable quantity of the prod-
uct is made into paint. The zinc should
bo free from cadmium, as this would give
tho paint a yellow instead of a white color.
Sovoral trial lots of zinc have been shipped
to a smelting plant at Hamilton, Ontario,
for treatment, and the results, if under-
stood, are satisfactory. The ore comes
from one of tho big dumps at the A. Y.
and Minnie, and while the Canadian
smelter ostensibly takes it for the zinc,
paying f. o. b. Leadville, the plant saves
not only the zinc but the lead and silver
also.
Wood & Mulrooney will put in a pump
in the Greenback mine at Leadville; triple
expansion, capacity to throw 1000 gallons
of water per minute from a depth of 1100
feet. The pumping station at the 1000-
foot level will be 18x50 feet in the clear.

aconda gulch 12 feet per day. A new
equipment has been put on, including a
tramming engine operated by compressed
air.
The Gillett Reduction Works, at Gil-
lett, north of Cripple Creek, has shut
down. This plant was the first in the dis-
trict to treat ore by the chlorination pro-
cess; newer and larger mills have been
built in other places.
The Record hears of a projected consoli-
dation of properties in the vicinity of and
adjacent to the Isabella, the idea being to
organize a corporation having a capitaliza-
tion of $5,000,000, probally known as the
Isabella Con. Mines Co., to absorb the
properties of the Acacia, Arrow, Hart,
Isabella, Orphan and probably the Pinna-
cle, the holdings of the company not to be
purchased outright, but the holders of
stock in them to have issued to them new
scrip in exchange for the shares they held
at the time the consolidation went into ef-
fect. The present market value of the
mines is $3,359,900.
The fine mining plant on the property
of the Gold Coin M. & M. Co. at Victor is
in operation. The double hoist, capable
of lifting from 3000 feet, and all accessory
parts, give satisfaction. The compressor
plant of thirty drills is also in operation.
The management expect that this plant
will be raised to sixty drills. The present
compressor is run with steam; the second
set of drills will be run by electricity. The
entire plant all over this mine is convert-
ible from steam to electricity with but
small changes in the machinery.

FLATHEAD COUNTY.
Inter-Mountain : A. Hill has completed
his report on the Snowshoe mine. When
received it will be for the present owners
to determine whether or not they will put
more money in the enterprise, in order to
make it a dividend payer, or to put the
mine on the market, sell it for what
it will bring, and let the purchaser
do that part. Conservative mining men
do not believe that the Snowshoe,
as it is, can ever be profitably worked
under the conditions that now exist.
If the mine is to be worked, the first
thing to be done is to explore the ledge by
sinking, and determine the extent of the
ore body. To do this, and do it right,
will probably require the expenditure of
not less than $50,000. If this is done and
the showing is of a favorable character,
then it will require more money before
the mine can ever become a dividend
payer. To be worked successfully, and to
secure water to run the concentrator the
year around, as has been stated before, it
will be necessary to operate the mine from
the Cherry creek side. Then, of course,
new works will have to be built, and if the
product is to be handled so that there
may be no glut, it will be necessary to
build a railroad from Libby to the mine.
To do all this will require an expenditure
in the neighborhood of $500,000. Will the
present owners put up this amount of
money? This is a plain statement of the
facts and the conditions that affect the
Snowshoe mine.

C. J. MOORE, back from London to
Leadville, tells the Chronicle of the meth-
ods by which large mining companies are
floated on the London market. The stock
is placed through large brokerage con-
cerns, who are enabled by means of an ex-
tensive clientele to control large sums of
money. The Independence deal, for in-
stance, was brought about in this manner.
Several large brokerage firms secured big
blocks of the stock, and then notified their
customers of the figure at which it could
be purchased, asking how much of the
stock was wanted. The customers of the
brokerage firms are men of wealth who
are seeking investments, and who place,
as a rule, great reliance in the recom-
mendations of their brokers. A man who
receives a notification that such and such
a stock is for sale, and that he can get in
on the ground floor, usually will subscribe,
as in case of a refusal he is dropped from
the list, and he doesn't want to miss a
good thing. There are about 2500 people
holding stock in the Independence, for
which they paid $2 5s.

Smelting Furnaces and Equipments.
In this advertisement we show out of a recent Silver-Lead Cast Iron Water Jacket Furnace.
Some metallurgists prefer jackets made of steel plates, and under some conditions plate copper is
demanded, although more expensive. Most of the important smelters are using cast-iron jackets
now, hence we give prominence to that material. There are absolutely no conditions in blast fur-
nace practice but are as well subserved by properly proportioned cast-iron jackets, as by those of
any other material.
Write for our catalogue, showing many different styles of smelters for the treatment of
QOLD, SILVER, LEAD, COPPER AND NICKEL ORES,
also the latest and best method for the economical use of jacket water (a saving of 80% to 90%
guaranteed) by our patented
WATER VAPORIZING ATTACHMENT.
We design, manufacture and erect Mills for Concentration and Amalgamation, Milling, Chlorination and Cyanide Processes. In writing for information, give us the
analysis or character of the ore to be treated, to enable us to intelligently arrive at the proper method.
Our very complete catalogue of CRUSHING MACHINERY will be sent on application.

CROWN GOLD MILLING CO
Manufacturers of the "CROWN" CONCENTRATOR and CROWN
ORE SIZER. A dry process of sizing and concentrating ore, sand or
gravel. Designed to accord fully with the laws of specific gravity,
and especially adapted to refractory ore or localities where there is
no water.
The chief claims for the Crown Concentrator are that it occupies
less floor space and has nearly four times the capacity of any wet
concentrator; that it will concentrate ores containing base and refrac-
tory metals that ordinarily slime and carry off values; that it effects
a saving of values far above the ordinary methods of concentration.
We have, now in operation, a complete plant
for crushing, sizing and concentrating ores by the
Crown Dry Milling Process.
Mine owners desiring tests made can forward
us, freight prepaid, not less than 1000 lbs. nor
more than 4000 lbs. of sample, for which a
charge of $20 will be made. (This amount in-
cludes assaying, etc.)
Ores for which this process is adapted and of
which consignments are solicited are any con-
centratable ores, pulps, tailings, or sands, carry-
ing sufficient values, whether they have hereto-
fore been profitably concentrated or not.

and analytical balances, to
The adjusting device will appeal to
the asBayer aB the simplest and most
convenient means of checking the
i beam, and consists of a star wheel on a
1 threaded arbor, mounted on the center
edge back of the beam.
By turning thiB wheel backward or
forward, it is moved along the arbor
and so adjusts the beam to equilib-
rium.

XHE GRIFFIN
THREE ROLLER
ORE TWILL.
The Griffin Three Roller Ore Mill is a simp.y constructed Mill, suitable for working all kinds of ores that
require uniformly fine crushing by the wet process. This Mill is a modification of the well-known Chilian
Mill, but the rollers run upon a crushing ring or die, which is inclined inwardly at an angle of about 30 degrees,
the rollers themselves also being inclined to the central shaft of the Mill, thus utilizing the centrifugal force,
as well as the weight of the rollers themselves as a crushing agent. The Griffin Three Roller Ore Mill is there-
fore a Mill of great strength, and has few wearing parts. We construct these Mills with extreme care, using
only the best of raw materials, which are most carefully worked by men who are specialists as mill builders.
We sell the Griffin Ore Mill on its determined merits, and will gladly supply full information regarding it to
any one.

THE IMPROVED BARTLETT CONCENTRATING TABLE.
The BARTLETT CONCENTRATING TABLE has been GREATLY IMPROVED recently by the substitution of iron
in place of wood wherever possible. It is now built with SOLID IRON TOP, PLANED TO A TRUE SURFACE AND
POLISHED ; all parts are made by template and EACH PART BEING INTERCHANGEABLE. As now constructed,
the table has no special wearing parts and will last for many years. It has a CAPACITY OF FROM FIFTEEN TO
FORTY-FIVE TONS IN TWENTY-FOUR HOURS, according to the class of ore worked. It is the only table in the
world which will take the place of jigs and do away with all costly and complicated machinery.
It is Especially Designed for Separating: Zinc from Lead.
Send for our illustrated catalogue, containing all the latest information on the concentration of ores.

FOUR and SIX=F0OT FRUE VANNERS
With Brovi/nell " Patent Lip" Flange Belts.
STANDARD MACHINE OF THE WORLD.
When a Concentrator like the Frue Vanner has been on the market nearly two decades, and the sales have constantly
increased, it is safe to say it is the ' ' Standard Machine of the World." More Frue Vanners have been sold during the last
twelve months than for the same period at any time during the history of the machine. Practical mining men in all parts of
the world where mining is carried on will testify as to its merits. It is the "standard " which all competitors are trvine to
imitate.
The results obtained by this machine are the "acme" of concentration, and several cheap and untried machines that
s=}? have lately come on the market compare by it. The manufacturers will tell you that they are "just as good and
=gf cheaper," etc. The facts are that no other concentrator made has an equal capacity, or will yield as clean a concentrate
=gp with as small loss in the tailings as the Frue Vanner. The amount saved from the lower first cost of an Inferior machine
counts little in the year's results, when compared with the increased output from a Frue. This machine not only gives bet-
ter results at both ends of the belt (i. e., clean product and poor tailings), but is operated at less expense and requires less
attention than any other machine on the markrt. At the Alaska-Treadwell mine, where they have ordered over 350 Frue
Vanners, one man attends 48 machines for 12-hour shift.

Buying Mining Stock.
From general newspaper discussion it is manifest
that the fact is now well recognized that a stock
company is a preferred way to get money for mine
development, but there still seems to be considerable
discussion in and out of the newspapers as to
whether the stock so issued and sold shall be assess-
able or non-assessable.
In California there is no option, all mining stock
being there subject to assessment, but in other
States there is nothing in the law to prevent organ-
ization upon either an assessable or non-assessable
stock basis. The latter plan is often adopted by
those organizing a mining stock corporation, in the
belief that such stock can be more easily disposed of;
this belief being based upon a sort of sub-belief that
those likely to buy the stock might shy at the
assessable clause, fearing that they might be frozen
out by unwise or unwarranted assessment.
As between assessable and non-assessable stock,
the former is the better. Where one buys stock in
an undeveloped mining property he presumably buys
it for profit, one possibility of such profit being
through having the property developed into a paying
mine. This latter result is more often secured by
assessable than by non-assessable stock companies.
Although what might appear to be sufficient mining
stock is set apart and sold for development purposes,
it is, from the very nature of the case, usually sold
so cheap that the money raised is not enough to de-
velop the mine to a point where it will begin to pay
dividends, so that when the money so raised is ex-
hausted there is ordinarily no way to raise any more,
the mine may be abandoned, all that has been in-
vested lost and the stock useful only for wall-paper-
ing purposes.
Of course, this is not invariable, but it is not an
overdrawn statement of a common result. Where
the stock is assessable and it becomes necessary to
raise enough funds to go ahead a small assessment
permits of such progress. Where a stockholder feels
it a hardship to pay out any more money, he. has the
option of selling a part of his stock to pay the assess-
ment on the remainder, or can decline to pay any
and quit, selling his stock for what he can get for it,
in the latter event being no worse off than were he
to have stock in a non-assessable company that would
result the same way.
The great trouble with non-assessable stock cor-
porations is that there is no way to assure continu-
ance of work. It requires a constant unanimity of
opinion and intent to go ahead, and whenever any of
the stockholders become tired or discouraged or
financially embarrassed, the load on the others, who
are desirous of going ahead, is all the more onerous.
Of course, all this opens up a very wide discussion;
this whole matter of investing in mining stock has
had so much said about it that it is probably unneces-
sary to be taken up here in detail. It is not here
recommended that mining stock, assessable or non-
assessable, be bought without careful consideration
of all attendant circumstances; it is simply asserted
that as between the two systems the assessable is
the better.
Further Consolidation.
Consolidation being the order of the day, it is not
surprising to learn of the contemplated amalgama-
tion of the Gold & Silver Extraction Co. of America,
Ltd., and the Cassel Gold Extracting Co., Ltd., to
be known as the Allied Cyanide Companies of America,
Ltd., with a capital of £110,000, divided into 110,000
shares, £l each, 35,000 of which are to be preferred
shares. The directors are to be Wm. Forrest of the
MacArthur-Forrest Process, J. R. De Lamar of
Colorado, Utah and California and Henry A. Jones,
managing director of the Cassel Extracting Co.,
Ltd., of Glasgow, Scotland.
The proposition is to buy and work under British
management with a local advisory board in Denver,
the MacArthur-Forrest cyanide patent business of
the Gold & Silver Extraction Co. of America, Ltd.,
and the zinc dust precipitation patents of J. R. De
Lamar, the Denver advisory board to consist of
Hugh Butler, Wm. H. James, Phillip Argall and Geo.
A. Anderson, the latter to be general manager. An
option has been secured on the Kendal patents.
The directors are advised by patent counsel that
the patent which expires soonest should, under a re-
cent change in the U. S. patent law, endure for six
years, which would put the MacArthur-Forrest
patent over to 1908. It is intended that the busi-
nesses be taken over November 1, 1900. It is also
understood that, inasmuch as the development of the
contemplated consolidated company's business would
naturally affect the consumption and sale of cyanide
in the United States, it is contemplated that a com-
bination with cyanide manufacturers would be of
further mutual advantage. It is further contem-
plated that properties susceptible of profit by being
worked by the cyanide process could be acquired. It
is understood that since 1893 the gross income of the
Gold & Silver Co. of America, Ltd., has been in the
neighborhood of $300,000, of which about 90% was
from royalties.
An Unearned Award.
An editorial paragraph in the issue of the 6th inst.,
regarding the Paris Exposition, said that the whole-
sale granting of gold medals and honors brought the
whole matter of awards into contempt. A manufac-
turer who himself rightly received the deserved
award of a gold medal writes, questioning the fair-
ness or accuracy of the statement. The assertion
referred to was made advisedly and direct proof is
available. An instance is to hand in California where
notice was received by one gentleman from the Ex-
position authorities in Paris that a gold medal had
been awarded to him for an exhibit made by him in
Paris. The gentleman was naturally surprised, in-
asmuch as he had made no exhibition of anything,
directly or indirectly, at the Paris Exposition.
Upon inquiring about it from one member of the
California Paris Commission, he learned that in the
judgment of that member if he had not received a
gold medal he deserved one anyhow, on general prin-
ciples; that such award had been recommended by
that commissioner, and that it was because of the
latter's recommendation that the gold medal had
been " awarded " to him. This is perhaps sufficiently
indicative of the manner of award, and is doubtless
equally indicative of the value of any prize capable of
being so " awarded." If every one in California and
the other forty-four States of the Union who might,
could, would or should have secured a gold medal,
had he or she exhibited anything at the Paris Fair
worth exhibiting, but who did not exhibit anything,
were awarded a gold medal, the demand for that
precious metal might cause a rise in its price; but,
from our standpoint, it is believed that, as in the
case cited, the whole business has what seems a dis-
honest flavor. It is not only dishonest, per se, but is
unfair and dishonest to the really deserving who won
medals by merit and who are justly entitled to them.
It makes ridiculous the whole affair, and it is because
of this fact that the paragraph in the issue of the
6th was written, very mildly, but none the less
truthful. It is fair to assume that since what we
have cited above was done in the case of the Califor-
nia man, it could have been done, and was done, in
sundry other cases. In all there were 34,852 medals
"awarded." If each one of the 34,852 has to pay,
say $12 or $15 apiece, to get his medal, the total
ought to be quite a nice little sum for some one.
We would not detract from nor decry the value of
any gold medal honestly earned by merit and exhibi-
tion, at Paris or anywhere else, but under the cir-
cumstances are inclined to the opinion that the an-
nouncement of such "award" is not universally en-
titled to the prominence in so many instances given
by the local press.

Millions of dollars have been spent in mining
machinery this year. (The readers of this paper
have paid out $100,000,000 for mining machinery in
the last ten years.) The makers and vendors of this
machinery, which is the finest of its kind, do not con-
sider mining to be the "gamble" that some people
claim it to be. They consider the business of mining
to be tangible, solid and legitimate as any other class
of industry that calls for fine up-to-date machinery
and pays for it. The sale of mining machinery at
good cash prices kept many a manufacturing concern
afloat through the latter nineties, and is the main-
stay of many a large establishment now. For what-
ever other industries may do in the credit line, "jaw-
bone " cuts no figure in securing mining machinery.
If one wants it he must pay for it. That is one part
of the business of mining, from which the " gamble "
is thoroughly eliminated. To the clear-headed men
who make the machinery the mining world is largely
indebted for the progress that their ingenuity has
made possible. Confident in being able to secure
cash demand for their product, they have at vast ex-
pense built up large factories and produced devices
that for applied power and efficient adaptability are
not excelled in any department of manufacture.
Colorado's State Supreme Court has strengthened
the rights of minority stockholders in a mining cor-
poration by a decision this week that will deter sub-
sequent attempts at "freezing out." The case was
on appeal. The Ibex M. Co. had a majority of the
stock of the Glengarry Co. and assumed control of the
latter company in its interest. It arranged a lease
and bond to itself of the Glengarry property in a way
unsatisfactory to protesting minority stockholders in
that corporation. There was no question of fraud
raised, the point being, could the Ibex Co., controll-
ing a majority share in the Glengarry, make disposi-
tion of the latter property contrary to the wishes of
minority stockholders therein. The Colorado court
holds that the Ibex Co. was virtually trustee of the
interests of all the Glengarry stockholders, and, as
such trustee, could not act in a manner contrary
thereto, and that the Ibex Co. in acting as it did,
tried to coerce the Glengarry stockholders into a dis-
position of their property at variance with true
trusteeship, saying in effect that corporation prop-
erty must be administered by its managers in a way
that shall tend to the use and benefit of all its stock-
holders.
Notable in the history of mining was the intro-
duction last Saturday of electric power on the Com-
stock, Nevada, not in any sense in the installation
itself, for electricity in mining has been in use a
dozen years, but as exemplifying what many con-
sider a new era in the life of that famous lode, which has
produced $400,000,000, and from which dividends ag-
gregating $120,000,000 have been paid. The history of
the enterprise has been so completely given in these
columns from the time that this journal urged the
move, to the present, that all necessary to now
chronicle is that on the 20th inst. the electric current
was turned on, starting the milling machinery. It is
figured that power can be thus delivered at an ex-
ceedingly low rate. This, coupled with other econo-
mies and modern mining and milling methods, in
connection with unwatering of the lower levels and
deeper workings should insure new life to the great
lode that made and unmade so many fortunes.

with the liberation of a great amount of heat. Almost
any explosive becomes comparatively harmless if mixed
with some neutral solvent.
A "knot" is 6086 feet. The indicated rate of 18.54
knots per hour made by the battleship Wisconsin, in
Santa Barbara, Cal., channel on the 11th inst., was at
the rate of 112,834.44 feet, or 21.37 miles, per hour.
To FIND the weight of castings by the weight of pine
patterns, multiply the weight of the pattern by 12 for
cast iron, 13 for brass, 19 for lead, 12.2 for tin, 14.4 for
zinc ; the product in each case will be the weight of the
casting.

The weight by which diamonds and precious stones
are calculated is : 4 grains = 1 carat ; 157J carats = 1
ounce troy. A fine diamond, perfectly white and pure,
weighing 1 carat is worth $100 ; 2 carats, $400 ; 4 carats,
$1100 ; 5 carats, $1750.
In the hands of an expert a blowpipe is of great value
in analysis, but for a prospector in the field its use or
value is limited. The services of a competent assayer,
even though at a distance and with attendant expense,
would be usually more satisfactory.
A boiler horse power represents the evaporation of
thirty pounds of water per hour from feed water at 100°
F. into dry steam under a pressure of seventy pounds by
the gauge. So that a 35 H. P. boiler is one capable of
evaporating 1050 pounds of water per hour from a tem-
perature feed of 100° F. into steam at seventy pounds
gauge pressure.
«'ast iron after solidifying in the moulds contracts
while cooling about J inch per foot of length. To allow

Foreign mining companies operating in Russia must
employ a Russian mining engineer to direct the work,

If a silver property will yield an average of fifty
ounces per ton, that at going rates is $32, and at the
ordinary mining and reduction charges that ought to
pay well ; pay better in these days of economic appli-
ances and improved processes than in the old days when
it was $1 per ounce.
When an invention becomes abandoned to the public
it is no longer patentable. Abandonment, however, may
not be presumed. It is only where the fact is made clear,
either by the testimony of witnesses or the action of the
party himself, that can be set up to defeat the inventor's
claim to a patent.
A movement originated some time ago in the Dawson
Board of Trade to reduce commercial gold dust from $16
to $15 per ounce; but one of the leading companies with-
drew from the agreement, and dust still continues to be
received at $16 in payment of all bills in Dawson, except
when otherwise specified.
Magnesite is largely used in making medical salts,
carbonic acid gas, and as a filling for wallpaper. Much
of the magnesite used in this country is mined in Greece
at a cost of about $3.50 per ton and brought to the Atlan-
tic ports for about $1.50 per ton more, selling in Phila-
delphia and New York for about $7 per ton.
Malleable castings are made by putting a gray
iron casting in a suitable box and covering it with pow-
dered red hematite, which is an oxide of iron, and keep-
ing it in a furnace at a bright red heat for from three to
thirty-six hours, dependent upon the size of the casting.
Malleable castings can be worked like wrought iron, but
will not weld.
To DRILL a hole in case-hardened iron or steel, heat
the steel or iron to a red heat, and while it is in the fire
drop a lump of sulphur on it just where the hole is to be
drilled. Take it out of the fire and let it cool off itself.
After the hole is drilled put it back into the fire, heat to
a red heat, sprinkle sal-ammoniac over it and plunge in
water to harden.
"The California Dustless Roads Co. of Los Angeles "
contracts to sprinkle with oil and keep in repair roads in
southern California. They have oiled 32 miles of roads in
Kern county, Cal.; cost per mile, $250. There is about 40%
asphaltum in the oil. The effect on the roads is some-
what similar to that when paved with asphalt, becoming
smooth and bearing heavy travel.
Babbitt metal is a soft, white metal used largely for
lining shaft bearings. Its usual composition is : Copper
4 parts, antimony 8, tin 24, melted together, and, before
using, the alloy is melted with an addition of twice its
weight of tin and applied to the bearings while molten.
So that the real composition of the lining is copper 4,
antimony 8, tin 96.
"Harveyized" steel plate for battleship armor is

projectiles before serious penetration takes place.
"Everybody is wiser than anybody," and whenever
anyone, anywhere, in any mining or metallurgical work,
knows of anything that he thinks would be of interest,
this paper would be pleased to publish the particulars,
and if accompanied by a photo or sketch, the latter to be
suitably engraved to illustrate the matter. In no better
or more practical way can mining and scientific progress
be advanced, and it is the men who do things who are
best qualified to write about what they have done, thus
adding to the stock of general information.
IN its pure state lead is unacted upon by pure water.
If air be present in the liquid or its surface be freely ex-
posed to the atmosphere, lead oxidizes, the latter uniting
with water and carbonic acid therein and becoming dis-
solved. Chloride of any kind in the water increases such
action ; sulphates or phosphates in the water check the
tendency to act on the lead. In case of poisoning by
acetate of lead, the stomach should be immediately
emptied by an emetic of sulphate of zinc, and then large
quantities of milk swallowed in which is considerable
white of egg. A good chemical antidote for such lead
poisoning is sulphuric acid in the form of a solution of
magnesium and sodium sulphate. Either of these salts
would decompose the lead compound, with the formation
of insoluble and inert lead sulphate. Alkaline sulphide
would give rise to the insoluble sulphide of lead. These
salts, however, are in themselves poisonous, in large
doses, and their use should be only with great care and
under the guidance of a physician.
Steel is made from wrought iron by adding a little
in, or from cast iron by extracting some of its car-
bon. There are three ways of doing this— the Bessemer,
Siemens-Martin and the cementation processes. Besse-
mer steel is made by pouring melted cast iron into a
converter through which a blast of air is forced. In this
way the carbon in the cast iron is burned out, leaving
almost pure iron. To this is added a certain quantity
of spiegeleisen, which is a compound of iron, carbon and
manganese, and then the molten metal is cast into steel
ingots. Siemens-Martin steel is made by melting wrought
iron and cast iron, or cast iron and certain kinds of iron
ore, together on the hearth of a reverberatory gas-fur-
nace. The cementation process consists of imbedding
bars of wrought iron in powdered charcoal in a fire-clay
trough and placed in a furnace for several days at a high
temperature. The iron combines with portions of the
carbon and forms blister-steel— so called from the blisters
found on its surface. Bars of blister-steel about 18 inches
long are then bound together by strong steel wire and
heated to a welding heat; then hammered and rolled into
bars called shear-steel.
A direct-acting steam pump is one in which there
is no rotary motion, the piston being reversed by an im-
pulse derived from itself at or near the end' of each
stroke. There is but one steam cylinder for one water
cylinder, the valve motion of the steam cylinder being
controlled by the action of the steam in that cylinder.
The peculiarity of the duplex pump is that there are
two steam cylinders and two water cylinders. The pis-
ton of one of these cylinders works the valve of the other
cylinder, and vice versa ; either can work alone. A
direct-acting steam pump does not work steam expan-
sively, from the fact that there would be danger of stick-
ing upon the centers in most cases if there was lap and
expansion, and to overcome this difficulty a small supple-
mentary piston is actuated by the main piston in several
different ways : First, the main piston strikes the tap-
pet of the small valve, which opens an exhaust passage
in one end of the cylinder containing the supplementary
piston, and having live steam pressing upon both ends of
the supplementary piston. Second, by the main piston
striking a rod passing through the cylinder head and
moving a lever which controls the motion part of the
main valve, to which is attached the valves which move
the supplementary piston. Third, the main piston rod
carries a tappet arm which twists the stem of the sup-
plementary piston, thus uncovering the posts, which
causes its motion. Fourth, a projection upon the main
piston rod engages the steam and operates the valve
which moves the supplementary piston, and is controlled
by steam. The kind of valves that are generally used
on steam pumps are the hinge, poppet and ball. The
hinge valve will let comparatively large bodies pass
through it. The advantage of the poppet valve is capa-
bility of being adjusted as to lift, quickness of closing,
and of being constructed of almost any kind of material.
The ball valve can be worked very hard with little in-
jury to itself or to its seat.
The " Swinburne process " of treating zinc in complex
sulphide ores consists of stirring the crude ore into a
bath of molten zinc chloride contained in a cauldron
heated from beneath. A small quantity of molten lead
in the bottom of the cauldron alloys with and entirely
removes the silver and gold from the ore, dissolving a
small portion of the lead as chloride in its place. The
rich lead is then withdrawn and the mixture of sulphides
and chlorides of lead and zinc is subjected to the action
of an electric current. The lead is first deposited as
molten metal, and collects in the bottom of the caul-
dron. No chloride is given off from the fused mass, but
sulphur, in the form of vapor, escapes. The action of
the current is continued until all the lead chloride is de-
composed and the zinc chloride begins to be acted upon.
By interrupting the process at this stage the lead may
be withdrawn. If electrolysis is continued further the
zinc is then deposited, also in a molten state, and col-
lected in a similar manner. The gangue and decomposed
matter, remaining after all the zinc sulphide has been
decomposed by the electric current, is raked out, and
this residue is heated in a retort, which drives off the
whole of the zinc chloride remaining, leaving nothing be-
hind but worthless residue. The zinc chloride so dis-
tilled is allowed to run in a molten state back into the
electrolyzing cell. For convenience of working, the pro-
cess is preferably divided into three operations. It is
much cheaper to deposit lead eleetrolytically than it is
to deposit zinc eleetrolytically ; therefore, should the
composition of any class of ore render it desirable, it will
be possible to stop the process short of the recovery of
the zinc. The cost of operating the process in Australia,
it is said, did not exceed $9.50 per ton of ore for complete
recovery of the lead and zinc, or $6.25 per ton, omitting -
the recovery of zinc. This process differs from others,
inasmuch as it extracts the precious metals first, and
then the lead, and finally the zinc. It directly splits
sulphides into sulphur and metal without any intermedi-
ate oxidation of the ore. The electrolytic process applied
to the recovery of lead is a comparatively simple mat-
ter, the same electrical energy required to deposit one
ton of zinc being capable of depositing upwards of three
tons of lead. Moreover, in electrolyzing fused chlorides
very high current densities are possible, so that the
apparatus employed becomes small in comparison with
that which is required for depositing metals in the wet
way.

The Oil Fields of Kern County, Cal.*
Written for the Mining and Scientific Press by
H. G. Parsons.
Kern River District. — After visiting the Kern
River oil district and obtaining ocular and olfactory
proof of the deposit of petroleum which underlies this
region, one marvels that these vast oil-bearing strata
should have furnished so little surface evidence of
their existence. At several points in the south San
Joaquin valley are visible within one acre more signs
of oil deposits than could be found in the entire 20
square miles embraced in the present area of the
demonstrated field along Kern river. AtMcKittrick,
Sunset and other places crude oil oozes from the hill-
sides, while asphaltum deposits and mineral springs
betoken the proximity of petroleum. At Kern
river, however, the surface indications, aside from
general geologic formations common to oil districts,
seem to have been confined to a small patch of oil-
saturated sandstone on the north bank of the
river — where the discovery of oil was afterwards
made — and to a gas well on the Barker ranch, 5
miles east of the surface croppings. These are the
only specific indications of oil in this locality that are
alluded to in a publication of the State Mining Bureau
devoted to this subject issued in 1894. Five years
after this the persistence of a small coterie of unsci-
entific laborers exposed the existence of a petroleum
formation, which, by its uniqueness and extent, is at-
tracting present attention. Prom the point of dis-
covery, on Section 3, Township 29 S, Range 28 E.,
M. D. B. & M., the demonstrated field has lengthened
and broadened, until now twenty or more sections of
land are embraced in what is locally called the
" sure " territory, and every few days a new well in
one direction or another proves the extended scope
of this deposit. Seemingly, the oil-bearing formations
do not lie in the apexes of main or lateral anticlines,
which are to be traced with scientific exactness by
geologic structure.
The richest stratum of oil-bearing sand — in
which most of the wells now stop — is struck at a
depth varying from 700 to 800 feet. This depth de-
pends upon the altitude of the surface location. At
present so clearly defined is this rich stratum that an
experienced driller can from his logbook foretell
within 6 or 8 feet the point at which he will strike
oil. Some of the earlier wells were stopped at a
depth of 500 or 600 feet in oil-bearing sand of less
richness and thickness than the stratum now se-
lected. The lower stratum is over 100 feet in thick-
ness, separated from a stratum above by a thin
streak of clay. Undoubtedly, many of the first wells
will after their productiveness diminishes be sunk
into lower strata and thus be given new life. There
seems to be a slight northwesterly dip to the forma-
tion, corresponding to the trend of the belt, so that
the wells in the northwestern end of the field are
sunk deeper than those to the southeast. Wjthin an
area of 6 miles in length by 3 miles in width there has
yet to be recorded a failure in striking oil, if the well
has been pushed down to a maximum depth of 1000
feet. Beyond the area mentioned several wells have
been sunk below the depth named without getting
into oil sand, demonstrating that the field terminates
or that the sand lies very deep.
There are now in the Kern River district at least
200 producing wells, with fully 200 wells in process of
drilling. As a well is completed within six weeks or
two months, it will be seen that the number will in-
crease at a rapid rate, even with the 200 rigs now
in the field. In addition to this, new rigs are con-
stantly being constructed. The output, as estimated
from railroad shipments and the consumption in the
field, is 5000 barrels per day. It is expected that
this output will be increased as soon as greater
tankage facilities are provided, or as soon as pro-
jected railroad spurs have been completed. At pres-
ent there are many wells which are capped, waiting
these desiderata. All of this development of oil re-
sources has taken place within the last fifteen months.
Considerable has been said about the Standard Oil
Co. entering the Kern river field for the pur-
pose of constructing tanks and ultimately handling
the product of the district. The producers are not
waiting for the Standard Co. They have formed an
association looking to the more systematic disposal
of their output, and they will co-operate on this line.
In the meantime three steel tanks, of capacities rang-
ing from 20,000 to 36,000 barrels, are completed, and
one company — the Aztec — has finished a cement cis-
tern of 30,000 barrels capacity, from which a pipe
line will run to the spur railroad track. The cement
cistern will obviate much of the evaporation which
inheres to the open-tank method of storing oil.
The possible wealth of the Kern River district may
be judged from the following sentence from another
article written by Prof. Cooper, where he says : "A
cubic foot of sand will hold l| gallons of petroleum oil.
A volume of sand equal in area to one acre, and 100
feet in thickness, will hold in round numbers 6,600,-
000 gallons of oil, or 167,000 barrels." The depth of
sand in the Kern River district is from 200 to 400
feet. In the demonstrated field $5000 per acre is a

common price, and contracts have been signed with
that figure as a basis, with option to purchase ex-
tending one year.
The petroleum drawn from the shallower wells,
mainly in the southern part of the field, is heavier
than that taken from the wells in the northern end.
The specific gravity of the former is 13° (Baume), of
the latter about 15°. In the case of the heavier oil,
steam is often injected into the casing at a point
where the oil is drawn, the heated steam increasing
the fluidity of the oil and making it easier to pump.
Steam is also injected into the bottom of the oil tanks,
making the thick fluid more ready to flow through
the outlet pipes.
Although considerable gas is present in the Kern
River oil, no systematic method of saving it has been
devised, as in the Coalinga field, where it is collected
at the various wells, conducted to a retort, and there
drawn off as fuel for different boilers. Occasionally
the inflammable gas causes disaster, as in the case of
the Sterling Company (as reported in the Mining and
Scientific Press of the issue of the 6th inst.), where
an open forge in the derrick enclosure set fire to es-
caping gas, the derrick being immediately consumed.
The presence of gas is evidenced by bubbles which
force themselves through the thick fluid, in a few in-
stances carrying oil over the top of the casing, and
thus creating flowing wells. Freshly drawn oil is
filled with minute gas bubbles ; as these escape the
fluid settles to a heavy, dark, viscid mass, somewhat
resembling thin tar. Thus the real production of a
well is sometimes overestimated, by reason of the
gaseous character of the product.
Oil wells in the Kern River district are sunk either
by contract with well drillers, or competent help is
employed by the companies at day's pay. Where
contracts are made, the price varies from $1.50 to $3
per foot. In a majority of instances the day's pay
method is adopted, because the companies' operations
are usually managed by superintendents, each of
whom may assume general charge over a dozen gangs
of drillers. Where a company desires to be economi-
cal, and wishes to sink first an experimental well, the
contract plan possesses advantages. It obviates the
direct employment of high-grade help and lessens the
preliminary investment, as contractors possess com-
plete drilling outfits of their own. In fields distant
from railroad facilities, contractors' prices run as
high as $5 or more per foot, in addition to which the
company must, of course, supply the casing and ac-
cessories. In such districts the well may cost $10
per foot. There is brisk competition among con-
tracting drillers at Bakersfield, and where several
bids are solicited a company may get its work done
at reasonable rates. A conservative estimate of the
expense of sinking a well 1000 feet in the Kern River
district is as follows :
Cost of rig for first well $2,200
Labor 1,200
Casing (1000 feet) 1.800
Incidentals covering accidents, etc 1,000
Total $6, 200
Deducting $2200, the cost of the rig — which is in the
nature of a permanent investment, available in drill-
ing other wells — and the net cost of a 1000-foot well
is $4000. The formations in this district are excep-
tionally favorable, as no boulders or inclined strata of
hard rock (those banes to the driller) are encountered.
This is shown by the log book of one of the companies
in the central part of the demonstrated field : First
15 feet in soil ; 15 to 50 feet, gravel ; 50 to 90 feet,
yellow clay; 90 to 220 feet, blue clay; 220 to 300
feet, dry sand ; 300 to 360 feet, sand, some oil ; 360
to 372 feet, white sand ; 372 to 384 feet, blue clay
384 to 409 feet, oil sand ; 409 to 443 feet, white sand
443 to 482 feet, oil sand ; 482 to 505 feet, blue clay
505 to 535 feet, oil sand ; 535 to 540 feet, blue clay
540 to 585 feet, oil sand ; 585 to 606 feet, blue clay
606 to 658 feet, oil sand ; 658 to 664 feet, blue clay
664 to 741 feet, oil sand ; 741 to 755 feet, slate ; 755
to 760 feet, oil sand, stopping in blue clay. This well
was started 125 feet above discovery well on bank of
Kern river.
The wages of workmen in the Kern county oil fields
are about as follows :
Per Day, with
Board.
Boss drillers $5 00 to $6 00
Tool dressers (helpers to boss). 3 00
Boss rig builders 3 00 to 4 00
Ordinary carpenters 2 50 to 3 00
Roustabouts 2 00
The above, as indicated, includes board and conven-
iencies for lodging in bunk houses, the workmen fur-
nishing their own blankets.
One of the most frequent causes of stoppage in a
productive well is the "sanding" of the pump. The
pump tubing is 2 inches in diameter, inserted in the
center of the casing, which is capped. The sand
which floats with the oil through perforations in the
casing acccumulates in such quantity in the tubing
that the pump valve becomes clogged. It is then
necessary to draw out the entire string of tubing,
and to bale the casing free of accumulated sand.
Then the cleaned pump, with its tubing, is lowered
into position and operations resumed. There have
been instances in which heaving sand, or that which
accumulates above the pump by the working thereof,
holds a pump so firmly in the casing that the pump
cannot be moved. Then the pump must be hydrau-
licked loose, or the entire string of casing has to be
drawn. This trouble involves great expense and
sometimes results in a ruined well.
Oil lands are now largely worked on long-term
leases, with option to purchase at a fixed price with-
in a year or two. Besides a cash bonus which is
often exacted for a lease, a royalty must be paid by
the lessee, varying from 10% to 50% of the gross out-
put from the land. This royalty is governed by the
'' sure" or the uncertain character of the territory
leased. In Kern River district the maximum royalty
is 50% ; a customary royalty is 33J% or 37£%, while
the option purchase price is $1000 to $5000 per acre.
There are usually conditions in leases to the effect
that drilling shall actually begin within thirty or
ninety days ; that a certain number of feet shall be
drilled each year, or a certain number of wells be
completed within a specified time, and usually one to
each acre. With the present feeling of confidence in
oil operations, the lessors dictate the terms. If not
suited, the contemplating lessee can take to " wild-
catting," as ventures are entitled which are located
outside of demonstrated oil fields. In outside districts
leases are effected at royalties ranging from 10%
to 25%.
The development of Kern county's oil fields has
given great impetus to the business affairs of Bakers-
field, the practical center of all the districts in this
county. It is estimated that there are employed in
this industry in the Kern River district alone 1000 to
1200 workmen. Besides this, employment is given
indirectly to many teamsters, freight handlers and
other classes of labor. Surely, Bakersfield has rea-
son to bless the day when old Jud Ellwood and Tom
Means uncovered the hidden wealth lying beneath
the barren hills of eastern Kern. She might appro-
priately perpetuate their memory by erecting in her
Chamber of Commerce, or in her contemplated Oil
Exchange, statues of these worthies cut from solid
asphaltum, with their feet anchored in the oleaginous
sands which have shaped the destiny of the city.
With reference to individual or company effort in
the Kern River district, many interesting and com-
mendable records have been made. I particularize
in the following instances :
J. J. Mack and John M. Keith of the Bank of Ba-
kersfield, with their associates, were among the pio-
neers in the field. They showed their faith in the
stability of the oil industry by the investment of capi-
tal when such investment meant a great deal in the
direction of development. They formed the Imperial
Oil Co., secured an entire section of land, and began
work in August, 1899, at a point where their sub-
company, "Thirty- three," have since registered such
a success. The latter company now have seventeen
completed wells, with four more drilling. They are
laying an 8-inch pipe line 5600 feet to the railroad
track. They estimate that their output will amount
to 1200 barrels per day. Besides owning Sec. 33,
28-28, the Imperial Oil Co. own all of Sec. 1, 29-28.
They have eight completed wells on territory not
controlled by "Thirty- three." Mr. Mack and asso-
ciates are interested in other lands and properties.
On account of this, and by reason of their commer-
cial position, they are considered important factors
in Kern county's present advancement.
Chanslor & Canfield were among the early opera-
tors in Kern River district. Their success at Coalinga
gave them prestige, and, when they evinced their
faith in the newer districts by investments, they
added impetus to the oil " boom." These gentlemen,
with their associates, notably Mr. Doheny, who met
with such success as a pioneer on Sec. 3, 29-28, Kern
river, organize companies and prosecute work
for the purpose of securing productive wells. They
are not sellers of stock, but are in the field as buy-
ers or lessees of land and shippers of oil. They are
connected with the Comet Oil Co., on Sec. 28, 28-28;
the Canfield, the Chanslor and the Doheny oil com-
panies, on Sec. 29, 28-28, and other enterprises in
various parts of the field.
The San Joaquin Oil & Development Co. began
operations one year ago. They own nearly 500 acres
of patented land in the Kern River district and lease
ten acres in the heart of the defined belt. On Sec. 5,
29-28, they are pumping from six wells, having here
a complete pumping jack. There are two good
water wells on this section. On the Means tract,
Sec. 3, they have four wells completed and ready to
pump, but no pumping jack. The company keep four
new strings of tools at work all the time, and by Jan.
1st, 1901, expect to have completed six new wells.
The product of the company at present is stated to
be about 750 barrels per day. They shipped during
the first half of October sixty-four carloads of oil,
are now completing a 6-inch pipe line, 1 mile long, to
the railroad track ; have tankage capacity of 42,700
barrels. They have eighteen of the small forest of
derricks which dot the field in their locality.
(A good idea of how this whole section of country
looks is afforded by the views on the front page, for
which I am indebted to the courtesy of the Bakers-
field Californian.)
The Central Point Consolidated Oil Co., on the east
side of Sec. 4, 29-28, has eighty acres leased from the
Bakersfield & Fresno Oil Co. on one-eighth royalty.
Work was begun on the property last March. In
May 1100 barrels of oil were delivered at the Santa
Fe station in Bakersfield by wagon ; in June, 3800
October 27, 1900.

493
barrels ; July. 4600 barrels ; August, 9200 barrels ;
September, 15,300 barrels. The oil during the latter
month was delivered direct from pipe line into the
cars on branch line running up Kern river. During
September this 15,300 barrels were pumped from six
wells. They expect that October will show an output
of 20,000 barrels, and think by the first of November
they will have eleven wells in operation, producing
about 30,000 barrels per month. The company is
capitalized at $200,000 ; par value of shares, $1 each;
B. P. Brooks, president ; L. Peyton, secretary ;
principal place of business, Bakersfield.
The Senator Oil Co. furnishes another good show-
ing. They paid $650 per acre for eighty acres in
Sec. 31, and have executed a lease to Fresno men
for 37*% royalty, lessees having an opportunity to
buy within eighteen months at $5000 per acre. The
three wells that the company have completed are re-
ported to be pumping 125 barrels oil per day each ;
No. 4 is down 735 feet, showing a body of oil sand ;
wells Nos. 5 and 6 are down 400 feet and 200 feet, re-
spectively. The Bear Flag Oil Co. have leased their
west 40, are putting up derricks and houses and ex-
pect to be drilling on their first well Nov. 1. As in
the case of the Central Point Con. Oil Co., B. F.
Brooks is president and L. Peyton secretary of the
Senator Oil Co. at Bakersfield.
The Aztec Oil Co. is another evidence of what the
Kern River oil district will show under careful man-
agement and energy. This company bought eighty
acres of the Kern Oil Co. May 25th and now has eight
completed wells, and are drilling on No. 9. They
have a storage capacity of 17,000 barrels ; pipe lines
laid to the railroad and facilities for loading nine cars
per day. The company is capitalized at 250,000
shares, of the par value of $1 each. The company
paid $1350 per acre for the land. The wells, drilled
to 800 and 900 feet, are producing 125 barrels of oil
per day and show a depth of 500 feet of oil sand. Their
principal place of business is at Bakersfield ; B. F.
Brooks and L. Peyton are president and secretary,
respectively, of the Aztec Oil Co., also.
The Petroleum Center Oil Co. own all of Sec. 8,
28-28, twenty acres in Sec. 28, 28-28, forty acres in
Sec. 24, 28-27 and eighty acres in Sec. 13, 28-29.
They have four producing wells on Sec. 28, with a
complete pumping plant; on Sec. 8 they have one
well in process of drilling; on Sec. 24 they are drill-
ing a second well, the first having been injured by an
accident, and it was then converted into a water
well. They operate two complete drilling rigs. The
Petroleum Center was the first company to strike oil
in Township 28-27. Operations were begun in De-
cember, 1899, and oil was struck the following Feb-
ruary. They are now 200 feet in oil sand. Dr. Wm.
Johnson has assumed management of operations in
the field, E. F. Beck (formerly in charge) having
gone East.
The Shasta Oil Co. are operating an extensive
plant in Sec. 14, 28-28, developing a considerable
amount of gas, are working in oil sand and expect to
get a gusher. Much development work is going on
in Township 28-27 and to the westward. Wm. P.
Todd is looking after the interests of the Shasta Oil
Co. in Bakersfield.
The Century Oil Co., on Sec. 24, 28-27, are near-
ing oil sand in their third well. Their neighbor — the
Santa Barbara Co. — dropped into oil at 850 feet.
The Petroleum Development Co. have their main
interests in the oldest part of the field, where they
did so much in the fall of 1899 to prove the abiding
character of the new industry. Their first well is
not 100 yards from the old discovery well of Jud Ell-
wood, on Sec. 3, 29-28. Around their enterprise and
that of the Treadwell Co. at this point a settlement
has sprung up amounting to a village, and dignified
with the name of Oil City, though it is thought Ell-
wood is a better name. The company started their
first well Sept. 14, 1899, on land leased of the Kern
River Land Co. and struck oil in twenty days at a
depth of 280 feet. They now go deeper, the average
depth of the twenty or more producing wells of the
company being 500 feet. The average production of
each well is stated to be forty-five barrels per day.
They shipped in September 18,000 barrels. They
keep three drilling rigs at work. Nearly all of their
wells are in the northeastern end of the field, close to
the river bank.
The Treadwell, or S. P. Co., have a cluster of wells
in the same neighborhood, both companies being con-
venient to the spur railroad track, which terminates
near there.
The Reed Crude Oil Co. is a large producer and a
vigorous prosecutor of development work. It is
composed of Los Angeles business men, who have
done so much by their energetic methods to advance
the oil interests of Kern county. They knew some-
thing about the oil business before coming into the
field, and their operations have been characterized
by the spirit of push which merits success. They
have nine producing wells on Sec. 34, 28-28; ten pro-
ducing wells on Sec. 28, 28-28, five drilling, with der-
ricks for five more; three producing wells on Sec. 32,
28-28, two drilling, one discovery, one water well and
four derricks; two producing wells on Sec. 20, 28-28,
and three drilling. They own forty acres on Sec. 2,
29-28, and 320 acres on Sec. 14, 29-28. Their esti-
mated output is 800 barrels per day.
The Monte Crista Oil Co., on Sec. 5, 29-28, have
one of the few flowing wells in the district. This well
is 1000 feet deep and daily yields nearly 150 barrels.
The average of their four producing wells is seventy-
five barrels per day each. They are drilling two
new wells and have a rig for another. Ordinarily,
this company has struck oil at a depth of 450 feet;
their oil stratum is 280 feet thick.
The Globe Oil Co., having forty acres on Sec. 30,
28-28, are pumping from four producing wells, yield-
ing an aggregate output of 400 barrels per day, and
drilling a fifth well. T. H. Noxon, the superintend-
ent, is a believer in deeper wells for the Kern River
district, and will drive his fifth well beyond 1000 feet.
The Grace Oil Co., on N. E. i Sec. 8, 29-28, have
three producing wells; have just completed a boiler-
house and are about ready to begin pum ping.
The Kern River Oil Co., having eighty acres on
Sec. 4, 29-28, are getting oil from four producing
wells. This company owns very productive property
in the McKittrick district. The Peerless Oil Co., on
Sec. 31, 28-28, have five producing wells, two drill-
ing, one being in oil sand at 550 feet. The Kern Oil
Co., on Sec. 32, 28-28, have one producing well, one
water well and three drilling; are planning to put up
three more rigs and are laying 5f-inch pipe line to
railroad. The Comet Oil Co., on Sec. 28, 28-28, have
two producing wells, one of them yielding at 460 feet;
50 to 100 barrels per day from each well. The Inde-
pendent Oil Co., on Sec. 28, 28-28, have two pro-
ducing wells, the one last finished yielding thirty-five
barrels per day, the other having settled down to a
steady product of twenty-five barrels per day. This
company own 160 acres in Sec. 2, 27-29. The Con-
tinental Oil Co. of Los Angeles, on Sec. 29, 28-28,
have two producing wells of 200 barrels each per day;
thev intend to put down fortv wells on forty acres.
The Canfield Oil Co., on Sec. 29, 28-28, have five
producing wells of 100 to 125 barrels per day, with
two wells drilling; have rigs for two more wells. The
Junction Oil Co., on Sec. 9, 29-28, have three pro-
ducing wells and one now drilling. Spellacy et al, on
Sec. 30, 28-28, have two producing wells, and are
now at work on a third. Several wells have struck
the oil sand in the northeastern part of the field, in
F. 28, R. 27, but the oil belt is not yet clearly de-
fined at this distance from the point of first dis-
covery. Those who own property in the trend, as
already defined, are very hopeful. Laud thereabouts
can not be bought for less than $150 to $300 per acre.
I visited many producing wells not mentioned herein,
but those described are types of those in the district.

Tests of Concrete.
Robins Belt Conveyor.
On page 376 of the issue of Sept. 29th appeared
some excellent notes on mixing concrete, the result
of U. S. engineering tests at Duluth, Minn.
It is to be further noted that the U. S. engineers
there adopted a plan for determining the real ten-
sile strength of cement when used in concrete.
During the construction of the concrete footing
blocks samples of the concrete were taken from the
mixing platform as mixed, from which briquettes
were made. These briquettes were treated as nearly
as possible to conform to the treatment of the con-
crete in the footing blocks. The results obtained
were satisfactory. In making these briquettes it was
necessary to remove pebbles more than I inch in
their greatest diameter to permit the concrete to be
compacted into the briquette molds. It was found on
breaking those briquettes that at twenty-eight days
and thereafter pebbles imbedded in the mortar at
the breaking section were almost invariably broken.
It will be seen from the table that the mean tensile
strength of five briquettes, one year old, was 643
pounds. Assuming a coefficient of 7 for strength in
compression would give 4501 pounds per square inch,
or 324 tons per square foot, as the ultimate resist-
ance to destructive stress in compression. The fol-
lowing table shows the tensile strength of briquettes
at different ages :

Robins Belt Conveyor.
The engraving on this page shows an exhibit of the
Robins Conveying Belt Co. of New York City at the
Vincennes machinery annex of the Paris Exposition,
for which the company was awarded a grand prize,
announced as the only one awarded to any manufac-
turer of conveying machinery. It consists of a 20-
inch Robins belt conveyor, 90 feet long, running level
under a series of bins, after clearing which it takes a
curved incline, elevatimg the material to a height of
7 feet, at which point it is delivered to a horizontal
20-inch conveyor, which carries the material in the
reverse direction. On this upper line of conveyor a
patent tripper operates, distributing the material
into the bins, reversing automatically at each end of
the bins and requiring no attendance. The capacity
of the system is 200 tons per hour, and it is con-
stantly in operation, handling broken stone.
The company also makes
i;wo other exhibits, one in
the machinery and elec-
tricity building, consisting
■of two 20-inch conveyors
35 feet long, and the other
in the mining building, con-
sisting of a one-quarter
size model, including the
automatic tripper, of the
Vincennes exhibit. These
exhibits are also in con-
stant operation. In addi-
tion to the machinery,
there is a large collection
of photographs of Robins
belt conveyors, showing
installations in all the min-
ing countries of the world.
While some of the pictures
were of interest to the Ex-
position crowds, it was the
conveyors themselves that
attracted the attention of
all, especially those on
which automatically re-
versing trippers were
working. This invention
had not been exhibited be-
fore in Europe, and the
smoothness and regularity
of its operation, requiring
no attention, occasioned
curiosity and interest. Spe-
cial Exposition illustrated

Successful Working of Cement
Gravels.*
Written for the Miking and Scientific Press toy
G. E. Bailey, M. E.
The famous "blue gravel" deposits that cover
large areas in the placer districts of California have
been for years the torment and despair of the miners.
The practical miner cares little as to whether they
are the result of glacial action, or torrential erosion,
or of some other cause, for he does know that they
have been deposited by some means in the ancient
channels of mighty rivers. He knows, also, that the
gold is more uniformly distributed in them than in the
more recent gravels, and that they yield higher re-
turns in gold per yard or per ton.
In some places they are capped by lava, sandstone
and other recent formations to a depth of 400 feet
and over, and have .to be mined like a coal vein.
Their values run from $2 to $20 per ton, the aggre-
gate in California being estimated bv official reports
as $400,000,000.
The blue gravels are so hard and compact that
they are commonly called "cement." They are too
hard to be reduced by the highest available heads in
hydraulicking. Stamp mills have worked at a profit
on them in many places in the State, but this is a
wasteful method, as the barren boulders have to be
crushed as well as the bonding material, which alone
carries the gold. The Adele Mining Co. have been
carrying on a series of experiments in Trinity county
since last July that have proven successful, and their
methods are of interest throughout the State. The
mill proper consists of six grizzlies, arranged so as
to form a barrel 6 feet long by 6 feet diameter. The
corners of the grizzlies do not join, but overlap, with
a 3-inch space between. Outside of and surrounding
the grizzlies is a set of screens, TV mesh. The cement
is fed into the barrel through an opening some 22
inches in diameter, and the boulders and coarse gravel
are discharged at the opposite end through an open-
ing slightly larger than that of the feed end. The
barrel is slowly revolved, making from twenty-five to
thirty revolutions per minute. In this way the ce-
ment is tumbled over and thrown down on itself, rub-
bing, crushing and grinding the bonding material,
but not crushing or wearing the boulders or coarse
gravel. Water pipes from a tank set 6 feet higher
than the mill throw jets and sprays with considerable
force upon all portions of the material being treated,
assisting in softeniDg the cemented matter and wash-
ing the boulders and smaller gravel absolutely clean.
The pulverized bonding matter passes through the
grizzlies onto the screens, and then goes with the
water to the amalgamators. If any particles are
too coarse to go through the screen they soon slide
back into the barrel at the corners where the griz-
zlies overlap. The speed and the feed being quickly
adjusted, it is found that the mill remains about half
full, the blue gravel being fed into the mill in a con-
stant stream at one end, and from the other comes a
steady stream of absolutely clean boulders and
gravel. The gravel as it comes from the mine runs
from 50% to 60% boulders and coarse gravel that
carry no gold, and all of this is discharged from the
machine uncrushed and thoroughly washed, no ce-
ment adhering to the rocks.
The capacity of the mill has exceeded the expecta-
tions of the company. With the very hardest mate-
rial it works from nine to eleven tons per hour ; upon
the medium material it has a capacity of from fifteen
to twenty tons per hour, while upon what is called
soft material, or that usually found hard to pipe in
ordinary placers, its capacity depends wholly upon
one's ability to get the material to the mill and away
from it.
The Amalgamators. — The amalgamators consist
of two tables 4 feet long by 3 feet wide, composed of
trays and fine riffles. These tables are adjustable
for grade and speed. They are given a gentle side
shake of 300 vibrations a minute. The' riffles are
filled three-quarters full of mercury. No mercury is
floured or shaken over. In fact, these machines
would make good amalgamators in a stamp mill. In
Trinity county it was found that a considerable per-
centage of the gold saved would pass through an
80-mesh screen, and nearly half of this would pass a
100-mesh screen, showing that the fine gold is saved.
The capacity of each of these amalgamators has
been found to be from three to six tons per hour,
according to the percentage of black sands and sul-
phurets in the gravel. As from 50% to 60% of the
material going to the mill does not reach the amal-
gamators, two of them are enough for one cement
mill. The agitation of the pulp keeps the sand in
suspension, while all of the gold is brought into con-
tact with the mercury.
The riffles are f of an inch wide by i of an inch
deep. The trays are quickly removed for clean-
ing up, extra ones being put in their places, and the
stoppage of the plant being only a few minutes.
Black Sands. — The Trinity cements carry a large
percentage of valuable black sands. Owing to the
large quantities of pulp handled per hour, it was
found that it would take too large a plant at the
present stage of the work to use the concentrators
*See engravings on front page.
now in the market. The process adopted during the
experiments was as follows : A revolving screen was
placed below the amalgamators to remove the coarser
sands, as all of the black sands are in small grains,
then the pulp goes on to a moving carpet table,
where clean water is added. The result is a par-
tially cleaned concentrate that is piled up to await
final treatment later on with some of the standard
tables. At all events, the black sands are kept from
going into the river. Test shipments of quantities of
the sands to the smelter show that the sands will
form a considerable item in the profit column.
Sulpetorets. — Considerable sulphurets have been
found in the cements near bedrock, but there has not
been time yet to fully determine their true value. It
is possible that they are of secondary formation, hav-
ing recrystallized in the deposit instead of being the
original sulphurets brought there by erosion from
veins. If this proves to be the case, the concen-
trator adopted for the final cleaning must be one
that makes two grades of headings, saving the black
sands and their gold and eliminating the sulphurets.
This is a point worthy of noting in other mines.
The Mine. — The mine on which this plant is located
presents some features of general interest. The ce-
ments here form the false bedrock of an hydraulic
placer that has been worked for years, so that min-
ing the cement is really a question of open quarry
work. On going down on the hard blue cements it
was discovered that the bedrock was pitching at a
rate of 20°, and that below the hard was a 7-foot
stratum of soft blue gravels that could be handled
rapidly with pick and shovel alone. This made it
easy to run in drifts and fired, small bank blasts
breaking down and shattering the hard cements in
large quantities, the problem, then, being simply one
of tracks, cars and hoist.
In General. — A few general points are worth not-
ing. This class of mills should not be expensive, con-
sidering their capacity. As the ore falls on ore, and
the process is a rolling one, the wear and tear of the
steel bars and steel end liners to the mill is insignifi-
cant when compared to any other style of machine.
A 30 H. P. engine and a 45 H. P. boiler is ample
power for the hoist, pump and plant. The quantity
of water necessary depends upon the quantity of
material put through. The green and black sands
are heavy and the hard cements require 200 gallons
per minute, the mill handling ten tons per hour, and
larger quantities will be in proportion. All launders,
etc., must be made unusually steep. Instead of a
car, future machines will probably use some form of
link belt conveyor for taking the boulders away from
the machine. The machine described was made for
the Adele Co. by the Krogh Manufacturing Co. of
San Francisco. Since the photos were taken the
machinery has been enclosed and some minor addi-
tions made. The total expense of mining and milling,
at ten tons per hour, is less than 30 cents per ton.
Pumping Oil in Colorado.
At Florence, Colo., the Oil Well Supply Co. of
that place has put in a pumping station such as is in
general use in Eastern oil fields, but new in Colorado
or California. It consists of a perpendicular shaft
upon which are two eccentrics with numerous holes
in them for attaching the wire line that runs from
the power to an iron jack at each well. It is mounted
on an iron frame bolted to a stone and cement founda-
tion, made on a slope corresponding with the lay of
the surface, and operated half a mile from some of
the wells. It receives its power from a gas engine
30 feet away, which takes its gas supply from one of
the producing wells. All that is required to start
all the wells that are attached to the plant is to start
the gas engine and throw on the friction clutch,
which starts the shaft on the power to revolving,
and the eccentric motion given to the wire pulls up
the sucker rods at the wells, just the same as if there
was an old-style engine and boiler there. It will
pump as many wells as there are holes for wires to
be inserted. If there are 100 wires and holes, it will
pump as many wells ; one man is required to operate
the plant ; under the old style of pumping it usually
required one man to each well.
The average production of each well drilled in the
Florence district is 100 barrels per day.
Forester Pinchot of the Department of Agricul-
ture says the age of the big trees on the western
slope of the Sierra Nevada mountains makes them
the oldest living things. Before the glacial period
the genus of big trees called Sequoia flourished
widely in the temperate zones of three continents,
and Europe, Asia and America each had its share.
But when the ice fields moved down from the North
the luxuriant vegetation of the age declined, and one
after another the different kinds gave way until only
the big trees and the redwood survived. These trees
have come down to us through the vicissitudes of
many centuries, solely because of their superb quali-
fications. Their bark is often 2 feet thick and almost
non-combustible. The oldest specimens felled are still
sound at heart and fungus is an enemy unknown to it.
Yet the big trees have not increased their range
since the glacial period, and have just managed to
hold their own on the little strip of country where the
climate is locally favorable.
Interior Department Ruling.
The Secretary of the Interior has denied the motion
for review filed by C. F. Blake and others for patent
to the Calumet lode mining claim and mill site, Sur-
vey No. 710 A and B, Boise. On May 19, 1900,
the land department held that these applicants had,
by reason of their delay of nearly seven years after
the expiration of the period of publication of notice
of their application, a,nd no further effort being made
for final entry, forfeited all rights acquired under the
previous proceedings upon application to get patent.
It was held, however, that they should commence
patent proceedings anew if they so desired.
In this motion for review it was contended that the
decision of May 19, holding that the applicants had
lost all rights by not having completed their applica-
tion within a reasonable length of time, was erroneous,
as such a ruling was contrary to the uniform decis-
ions of the courts, to the effect that a properly
located mining claim constitutes a property right
and estate of the locators, or their guarantee, and
gives them the exclusive right of possession.
" The department, however," says the Secretary,
"did not claim in its decision that the applicants
' have not exclusive right of possession and enjoyment
of their claim, and by virtue of the location thereof.'
On the contrary, it was stated in that decision: ' As
to the question whether the appellees have or have
not performed the conditions necessary to the main-
tenance of their possessory rights under the location,
the land department has nothing to do with such
matters, and can make no determination with re-
spect thereto. Its duty is to administer those pro-
visions of the mining statutes which relates to pro-
ceedings of obtaining patent from the Government,
and it is with reference only to the application for
patent, and the proceedings had thereon, that any
determination is intended to be made in this case.' "
Thus, according to the decision of the Secretary,
there is nothing in the contention that the possessory
rights of the mineral claimants have been injuriously
affected by the action taken by the department in
the former decision, as it was with respect to their
rights as applicants for patents that the department
dealt in this decision of May 19, 1900. It was not
held that the claimants had waived their possessory
rights, but on account of their delay had waived all
rights acquired by the earlier proceedings upon their
application and could take nothing under those pro-
ceedings, but that they could renew proceedings for
patent should they so desire. Under these circum-
stances, the Secretary decided that there was no
reason for entertaining the motion for review, and it
was accordingly denied.
Electrical Machinery in South Africa.
The British and South African Export Gazette says
that during the last ten years on the gold-bearing
reefs of the Witwatersrand a marvelous collection of
machinery of all sorts has been installed over a sec-
tion of country about 40 miles in length. There is
yet room for a great deal more, as many of the small
mines have never been properly developed and many
of the large mines have neglected their extensions
and deep levels. It will not be many months before
the mines will be again occupied and the question of
new electrical machinery gone into. Then it will be
seen how much of the old machinery has been irrep-
arably damaged by neglect and by water ; and, in-
spired by confidence in the new state of things, or-
ders will go out broadcast for this machinery and for
plants which the mines have been waiting for years
to put down. New schemes will be taken in hand,
new districts developed, and every bit of machinery
will be wanted at once.
Inventor of the "V" Flume.
By the death of J. W. Haines the inventor of the
" V " flume passed away. Haines was in the wood
business in Washoe in the early days and constructed
a box flume to carry wood out of the mountains. The
square flume didn't work. Haines looked over the
big line of boxes and turned one sidewise. He found
that the water was confined to less space and less
room for friction. The order was given to turn the
whole length of flume on its side, which was done,
and the result was that the wood went booming down
the hill. From that day the transportation of wood
from the steep canyons has been done by means of
Haines' " V " flume, and although no patent was ever
taken out it proved the greatest invention the wood-
men ever had. — Virginia, Nev., Enterprise.
Several Colorado mine shafts are being equipped
with cages having safety chairs attached, to prevent
accidents to cages in passing down the shafts. By
their use the old method of a set of chairs for each
landing is eliminated, the chairs being carried at-
tached to the cage, and are always under the control
either of the cage man or the station man. The
chairs, which are flanges, which may be thrown out
at will, are designed to prevent accidents and loss of
life through neglect to remove stationary chairs from
the landing, upon which the cage would drop with
force in the descent, often crushing the cage and in-
juring or killing the occupants.

Written for the Mining and Scientific Press
by A. E. Chodzko.
"Giant" Rook Drills. — Compressed Air Machin-
ery Co., San Francisco: Valve motion, tappet;
feed, hand ; rotary motion, stationary pawls, mov-
able ratchet head.
Valve motion : The plain slide valve used in this
machine is now being superseded by a different
arrangement, consisting of a balanced piston valve,
both ends of which are fitted into cylindrical cham-
bers, open to atmosphere when the drill is working
at full stroke. This type of valve is claimed to re-
duce the wear of the tappet.
When it is desired to beat at reduced stroke a turn
of a cock replaces atmospheric by working pressure
into the rear valve chamber, thus throwing the valve
forward as soon as the tappet is relieved of its con-
tact with the main piston. This arrangement aims
at the same object as the G-leeson device, described
in connection with another local machine of the same
type.
Rotary motion : The ratchet head, keyed on the
rifle bar, has teeth symmetrically shaped, and which,

when worn on one side, can be used on the other by
changing the setting of ratchet head on bar, end for
end. Pawls pivoted into hardened steel bushings
take up the thrust and prevent cracking of the
back head, which was of frequent oc-
currence prior to their adoption.
Shell strips : The cylinder is cast,
as usual, with side slides moving longi-
tudinally into corresponding grooves
carried by the shell.
The upper part of each groove is
here made of a bar held down by cap
screws passing through oblong holes,
and bearing against a ridge cast with
the shell. As cylinder slides are work-
ing loose, bars are made adjustable by
slackening the screws and shimming up
between bar and ridge, then jamming
the screws again.
Clamp : The shell is cast with an in-
verted conical recess, i. e., the larger
diameter inward and the smaller di-
ameter outward. The clamp connect-
ing the shell to tripod or column
carries a boss of the same shape as re-
cess, one half of which is stationary,
while the other can be moved nearer
to or farther from it by acting on a
single bolt. When both halves are
brought together the boss can be en-
gaged into the recess of the shell, and
then, by tightening up the bolt, they
are spread apart, which sets the
clamp.
Chuck : Instead of the bolt gen-
erally used for jamming the half bush-
ings in the chuck around the shank of
the bit, a single bolt is here used
for this purpose, the claim being to
avoid the frequent breaking due to
unequal tightening of the bolt's nuts.
A goose neck and special clamp
are also used for connecting the air
hose to the machine. They have
been illustrated and described in a
former issue of this paper.
The Cummings Drill. — Valve mo-
tion, Eclipse type; feed, hand; rotary
motion, stationary pawls, movable
ratchet.
This machine was designed to work
upon the double pipe system, the ex-
haust air leaving the drill at a pres-
sure considerably above the atmos-
pheric, and being returned to the
compressor through a closed pipe.
In this respect the Cummings drill is
at marked variance with all the
other machines in use at the present
day. An application of it, mentioned
in this paper some months ago, is re-
ported by the inventor as made with
220 pounds live pressure and 100
pounds return or exhaust pressure,
all effective, the average speed of
the machine being 300 blows per
minute.
In its general appearance, this ma-
chine does not differ from the more
familiar types of rock drills. In fact,
no particular feature is claimed for
the feed and the rotary motions ;
neither is any special design recom-
mended for the shell, Clamp, column
or tripod, machines of this system
having occasionally been used with
other makes of these several pieces.
The Cummings drill receives per-
manently the live pressure on the front end of its
piston, whose working size is therefore that of its rod
at the stuffing-box.
At the same time, the valve chest is removed near
the rear end of the cylinder, the object being to
shorten the rear port, and thus reduce the clearance,
of which there is none at the front end.
The piston valve is operated by admitting live pres-
sure at the proper time into the end casings of the
valve chest, through separate ports, of which the
other ends are alternately covered by the main pis-
ton, or put in communication with the live pressure.
These end casings exhaust through a passage drilled
clear through the valve, communicating with the
main exhaust of the cylinder. The scope of this arti-
cle would not admit of a comparison between the
double-pipe system and the ordinary way of operat-
ing rock drills ; besides, the former applies to any
kind of pressure motors, of which rock drills are only
one particular case, and a treatment of this subject
would unavoidably extend beyond what the title of
these remarks implies.
It is, moreover, noteworthy that the double-pipe
machine is the only one where an effective attempt
can be made to complete expansion without the use
of a reheater.
The Firth Drill. — Valve motion, auxiliary valve ;
feed, hand ; rotary motion, stationary pawls, mov-
able ratchet head.
Valve motion : Operated direct from the piston,
the auxiliary valve resting on a tapered part of it,
with a hard steel ball interposed.
Valve seats provided with a liner, which can be
changed, when worn, without removing the entire
valve chest, the latter being cast with main cylinder.
Rotary motion : With hardened steel reversible
pawls swinging on head bolts.
Adjustable feed nuts to take up wear of feed screw.
The side guides of cylinder are engaged into corre-
sponding solid V-shaped grooved bars, secured to
cylinder by means of excentrically turned bolts, so
that a slight angular motion of these will move the
whole guide bar towards or from the cylinder guides.
Cast steel clamp of the Ingersoll type, with T-
headed bolt which a partial turn can engage or dis-
engage from shell.

ated by the tappet in the usual way; but the possibil-
ity of beating at reduced stroke is assured by a
special addition, known as the Gleeson device. This
consists of boring out a portion of the rear end of the
valve chest, to form a small cylinder, in which is a
plunger, marked 22, having attached a stem, 24, j
around which is wrapped a spiral spring, 26. The
device is acting when the stem is brought in contact
with the valve ; it becomes inoperative when this con-
tact ceases.
The small cylinder is capped by a brass plug, as
shown, and on one side of its forward portion there is
a plug cock, 33, with a handle about 1* inches long.
The stem of the plunger has a working fit into the
rear end of the valve chest, as also the plunger into
its cylinder ; but the air pressure will pass around
them to some extent.
When the device is inoperative and the drill works
at its normal stroke, the pressure acts on both faces
of the plunger, which, being balanced, is pushed back
by the spring, 26. But if the cock, 33, is given a quar-
ter of a turn the chamber in front of the plug is open
to atmosphere, while its back end is under pressure,
overcoming the action of the spring, 26, presses the
plunger's stem against the valve, 6, thus throwing it
forward as soon as the tappet abandons it.
What little air would leak into the front chamber
of the plunger escapes continually, and the device re-
mains operative until the cock is turned back, when
the plunger is instantly thrown away from the valve,
6, and becomes inoperative.
The general features previously described are here
retained, a distinctive detail being that the ratchet
teeth are out on the inside of the rear end of the cyl-
inder, thus dispensing with a separate ratchet head.
No adjustment is provided for the slide bars.
The bolt use for the chuck has a releasing wedge
on top of it.
The recess for connecting shell to clamp is made in
the latter, which is machined in every bearing.
This machine was designed as and is claimed to be
a one-man drill.
Another feature consists in an adjustable connec-
tion between the air hose pipe and the drill, by means
of a J-inch pipe, passing clear through the valve
chest, perforated with i-inch holes to the extent of
its area, and jammed into position by a bronze nut at
its outer end. The hose coupling is permanently
closed, and connecting to the drill is made to suit any
inclination by loosening the brass nut and jamming it
again after proper setting.

Poisons; Their Nature and Effect.
A poison is any substance which, when taken
into the body and absorbed, or by its direct chemi-
cal action upon the parts with which in contact, or
when applied externally and entering the circulation,
is capable of producing deleterious effects. There is
no doubt that all poisons are to a greater or lesser
extent absorbed into the circulation. In fact, with
most of them this is certainly a condition essential to
the production of their effects ; yet it would appear
that in the action of some substances, which produce
local chemical changes, death, in some instances at
least, can be referred only to the effects of the
changes thus produced. The mineral acids and caus-
tic alkalies are the principal poisons which have a
direct chemical action upon the parts with which
they are brought in contact. This action is due to a
mutual affinity existing between the agent and the
tissue. In this respect the action of these substances
differs from that of certain heated liquids, such as
boiling water, which are inert at ordinary tempera-
tures, but which, simply on account of their condition,
induce a chemical change in the part to which they
are applied, without themselves being chemically con-
cerned in the change. When applied externally,
some poisons are absorbed by simply being brought
in contact with the unbroken skin ; while others do
not enter the circulation unless applied to an abraded
or wounded surface.
Poisons differ greatly in regard to the quantity
necessary to prove injurious. Thus, the fiftieth
part of a grain of aconitine has seriously endangered
the life of an adult, while, on the other hand, an ounce
of magnesium sulphate may generally be administered
with impunity ; yet in large
quantities the latter sub-
stance has in several in-
stances caused death, and is
strictly a poison, although
not commonly reputed as
such. As yet we know of no
substance that is poisonous
in every proportion. Any of
the most powerful poisons
may be administered in cer-
tain quantities without pro-
ducing any appreciable ef-
fect, and most of them may
be so employed as to con-
stitute valuable remedial
agents.
In medico-legal inquiries,
the leading idea connected
with the term poison is
whether the given results are
directly traceable to the sub-
stance and the intention with which it is employed.
Poisons do not differ from each other in regard to
the quantity necessary to destroy life ; but the effects
of the same substance may be much modified by cir-
An Electric Staircase.
At the Fifty-ninth street station of the Third ave-
nue line of the Manhattan Railway Co. in New York
City is now being given a test of an electric staircase
or inclined elevator, made by the Reno Inclined Ele-
vator Co., New York City. Similar apparatus have
been put in department stores in New York, Phila-
delphia and other cities, and the device has attracted
attention at the Paris Exposition.
Fig. 1 illustrates the elevator in position at
the station ; Fig. 2 is a section showing how
the moving platform ends at its upper and
lower extremities. The hand rail moves along
with the inclined floor of the apparatus, and at
the same speed, so that the passenger simply steps
on the moving incline, resting his hand on
the hand rail, and is carried at a moderate
rate of speed to the upper or lower floor, thus
doing away with the ordinary labor of "climbing
stairs."
The surface of the incline consists of a series of
shallow longitudinal rubber-covered ridges, which at
the top pass between the prongs of a comb-shaped
landing, as shown in Fig. 2. In this way the passen-
ger is slid out upon the landing without danger of
accident, such as a woman's clothing being
caught.
It is calculated that the average New Yorker
climbs about 20,000 feet a year up the elevated stair-

cumstances, and even substances which to most per-
sons are harmless may, on account of certain pecu-
liarities of constitution, produce deleterious effects.
ways. These elevators have a capacity of 3000 pas-
sengers each per hour. Small electric motors will
furnish the power requisite for their operation.

LAWRENCE COUNTY.
(Special Correspondence). — The Home-
stake Co. is constructing a water line
from near Spearfish to Lead, to furnish a
water supply for the mines, mills, cyanide
plant and for all city and domestic pur-
poses at Lead. The water will be con-
veyed through 11 miles of 28-inch vitrified
stone pipe to reservoirs and pumping sta-
tion near Lead. Reidler pumps, having
12,000,000 gallons capacity per day, will be
supplied with steam from 200 H. P. Scotch
marine boilers. The altitude at the intake
is about 6000 feet, and the fall along the
pipe line will be about 10 feet to the mile.
The three Homestake mills have an ag-
gregate of 700 stamps, and 200 more are
being added. Concentrators, below the
amalgamating plates, have been in use.
The cyanidation of the mill tailings is soon
to be an important feature of the work.
A new plant, strictly modern in construc-
tion, is being erected for this purpose and
will soon be ready for operating. The
main building is 340x100 feet, the precipi-
tating department 65x65 feet, solution
storage building 50x100 feet; the brick and
steel power house is 50x85 feet. The main
structure is frame, but sheathed with as-
bestos. The solution and sand tanks are
44 feet diameter and 9 feet depth. The
solution tank capacity will be equal to 8400
tons; and that tonnage of material will be
in course of treatment through the mill.
The material will be received and treated
in the same tanks — that is, there will be
no preliminary treatment. The tailings,
however, in traveling from the mills by
gravity to the cyanide plant, pass through
a system of cone-shaped classifiers, which
make a separation of the siliceous sands
from the slate slimes. The cyanidowork,
both as to construction of plant and oper-
ating same, is under the supervision of
C. W. Merrill, who still retains similar
connection with the Drum Lummon mill
of the Montana M. Co., at Marysville,
Mont. Wascott.

INDIA.
Bids have been asked of several electri-
cal engineering firms for equipping an ex-
tensive electric power supply plant in the
Mysore gold mining district. Current is
to be generated at the Convery Falls and
conveyed 100 miles to the gold mines. The
Mysore Government is to defray the cost
of the installation.
LOWER CALIFORNIA.
Supt. F. E. Russell, Aurora mine, Al-

MEXICO.
Final action in the protracted litigation
over the Weil and La Abra mining claims
against the Mexican Government in the
U. S. Supreme Court dismisses the appeal
of Alice Weil from the judgment of the
Court of Claims on the ground of non-
prosecution. In view of the adverse de-
cision in the La Abra case, the appeal was
not prosecuted. The balance of the in-
demnity paid by the Mexican Govern-
ment, amounting to some $200,000, will
probably be refunded.
L. Davis has leased the Cinco de May,
in the Escondido mountains, Chihuahua.
Men are at work and shipments will soon
begin.
SOUTH AFRICA.
The Rand mining companies are re-
ported disappointed by the delay in end-
ing the military campaign. They sent
engineers and agents to Cape Town when
Pretoria was occupied, where they have
remained in idleness month after month.
Engineers representing large mining in-
terests have been allowed to go to Johan-
nesburg and report on the condition of
the plants, but pumping operations have
not been resumed, and miners and natives
cannot be employed until the railways are
prepared to carry coal and supplies on a
large scale. The railways barely suffice
for the needs of the army, and it is not be-
lieved that the mines can be operated with
efficiency before the end of six months.
Cape Town cables: "All eyes are
turned yearningly to the Transvaal. The
return of refugees to Johannesburg has
now begun at the rate of a thousand ar-
rivals per week. Nevertheless, there ap-
pears to be little chance of any active re-
sumption of the mint output before the
beginning of 1901, nor does the prospect
of an early return of normal conditions in
the Transvaal just now look encourag-

Books Received.
"Free Hand Perspective, " V. T. Wil-
son, for use in manual training* schools
and colleges, 8vo, 268 pages, cloth, $2.50.
The entire subject is treated from a stand-
point entirely different from the one
formerly adopted, being more after the
plan of model drawing, the idea being to
apply the principles of linear perspective
to free-hand drawing, an effort in which
the author has achieved some measure of
success; published by Jno. Wiley & Co.,
New York City.
"Famous Gold Nuggets of the World "
is the title of an interesting little book on
that subject by T. J. Hurley of New York
City, in which he gives full credit to the
sources of his information and presents a
mass of data on a subject that must long
continue of interest to many.

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co.'s Scien-
tific PRESS U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Check Hook.— No. 659,611. Oct. 9,
1900. F. G. Snook, Sacramento, Cal.
This invention relates to a new and im-
proved harness check hook or device
for holding check reins in position. It
comprises a post having at its upper por-
tion a transverse slot or opening with a
notch forming a depressed sheet, a contin-
uation of the upper wall thereof and a
ring or loop pivotally mounted to the base
of the post and composed of spring mate-
rial; said ring or loop adapted to be passed
into the slot, and thus prevent the check
rein which is fitted on the post from slip-
ping off. The rein is easily released by
disengaging the ring and turning it back-
ward, leaving the upper part of the post
clear for the release of the check rein.
Track Cleaner and Oiling Device.
—No. 659,408. Oct. 9, 1900. Wm. Morck,
Peter Krickau and Wm. Boehle, Oak-
land, Cal. This invention relates to de-
vices for clearing the tracks of railway
cars from obstructions, and a means for
making the connection between the clear-
ing device which is carried upon the swiv-
eling truck and the car body which is
movable transversely independent of the
truck. The invention consists of brushes
having shanks slidable in vertical guides
on the truck, a transverse bar connecting
the shanks of opposite brushes, a second
transverse bar carried by the car body,
and a loose connection and guide between
this bar and the first named one, with
means whereby the second bar may be
raised and lowered so as to raise and
lower the first named bar and its brushes.
Spring Connection for Vehicles.
. —No. 659,798. Oct. 16, 1900. P. L. Jones,
San Francisco, Cal. The object of this
invention is to connect the contiguous ends
and end springs which an
conjointly upon buggies, carriages and like
vehicles. It consists in cutting away an In-
termediate portion upon each side of the
leaf near the end, leaving thooxtromo end
of full width, then folding and welding the
cutaway portion upon itself, with the end
part overlapping and welding upon the
end of the spring and rounding the folded
smaller portion to form a cylindrical
spindlo. The second spring meets the first
at right angles, and has the end bent into
a cylindrical form. A rubber bushing fits
within said end abuts within the collar of
the first named spring. A metal sleeve is
centrally fitted on said bushing and turns
upon the spindle of the first named spring,
and a nut and collar fitting upon the end
of the spring abut against the outer end
of tho elastic bushing. This forms a tight
and noiseless joint with sufficient yielding
to allow the change in position which
takes place during movements of the
springs.
Mail Pouch Closure and Fasten-
ing.—No. 659,796. Oct. 16, 1900. Geo.
Gavin of Eureka, and W. E. Griffin of
Reno, Nevada, assignod to the Safety
Mail Pouch Fastener Co. of Eureka, Nev.
The object of this invention is to provide a
novel and improved closure and fastener
for the mouths of mail pouches. It con-
sists in the application of front and rear
slotted plates, centrally located similar
plates fixed to the outer edges of the
pouch, and a central plate secured to the
front of the pouch below the previously
named plates, and having a staple fixed to
and projecting outwardly from it over
which staple all the other plates are folded
to overlap, so that the single lock or fast-
ening through the projecting staple
secures the mouth of the pouch. These
plates thus form a rigid border for the
closing edges, which prevent any access to
the interior and a single fastening is suf-
ficient to hold the parts together.
Conveyors for Ropeways. —No.
659,745. Oct. 16, 1900. A. S. Hallidie,
San Francisco, Cal. This invention re-
lates to conveying attachments to be used
for aerial wire ropeways or tramways, and
is especially designed for the transporta-
tion of sugar cane and other material that
can be made up into bundles or packages.
It consists essentially of slings in which the
packages or bundles are contained with a
pole or rod from which the slings are
suspended. This pole or rod is placed
upon carriers suspended from the rope
way, and thus the bundle is transported to
the point where it is to be delivered. The
delivery is effected by an automatically
unlatching device which disengages the
pole from the arm, and allows the bundle
to drop at the point of delivery.
Can Heading Machine.— No. 659,804.
Oct. 16, 1900. E. C. Atwood, Golden Gate,
Cal., assignor to Pacific Coast Syrup Co.
of San Francisco, Cal. The object of this
invention is to provide a device for heading
cans of that class in which the body is
made of pasteboard or like material with
metallic or other bottom, and metallic or
other head, and it is designed to apply
and crimp a metallic ring by which the
head is secured upon the top of a can after
the latter has been filled. It comprises
a frame having upper and lower guides,
vertical shafts mounted in said guides, one
of said shafts having a spring seated table
to support the can, and the other shaft
having an encircling sleeve provided with
a disk to rest upon the can head. A col-
lar is splined upon the sleeve and a treadle
and connections are employed for raising
and lowering the shaft. Fulcrumed arms
project from the disk and the collar, and
other arms are fulcrumed between their
ends to the arms on the disk and have their
lower ends provided with semi-globular
beaded heads which travel in contact
with the cover, and form an indented ring
which secures it to the body of the can.
Links have one end connected with the
arms on the collar, and their opposite ends
pivotally connected with the upper ends of
the arms which carry the beaded head. A
lever is connected with the collar and the
treadle and connection serve to operate
the same, so that the beaded heads may be
moved into and out of contact with the
securing rings. The device is then rotated
by suitable gearing, and the beaded heads
are caused to travel around in contact with
the cover until the latter is properly inter-
locked and secured upon the can body.
Automatic Weighing Machine. —
No. 659,923. Oct. 16, 1900. Geo. Hoep-
ner, San Francisco, Cal., assignor to the
Union Scale & Manufacturing Co., of
Sacramento, Cal. This invention relates
to machines of that class which are de-
signed to weigh powdered, granular or
similar substances, and to deliver such
substances in regular quantities into such
receptacles as may be desired. It consists
of a weighing receptacle, means for sup-
plying the material to be weighed thereto,
a fulcrumed scale beam with adjustable
weights, from one end of which beam the
receptacle is suspended, a plurality of
chambers within the receptacle, a tilting
partition, and mechanism by which this
partition is alternately moved from one
side to the other so that the material
arriving from the source of supply will
first till the chamber upon one side of the
partition until given weight has been
reached, and will then bo transferred to the
other side, thus alternating without inter-
ruption. In combination with this is a
mechanism by which an even feed is main-
tained, mechanism by which the parts are
mechanically actutaed and locked inter-
mediate of weir movements so as to gold
the tilting partition in position, and the
hinged movable bottom of the receptacles
so that the bottom of the one which is be-
ing filled will be closed while the other is
opened for discharge. The position of
these bottoms are reversed with the re-
versal of the partition which guides the
material into each compartment.
Receptacle for Packing Fruit. —
No. 659,949. Oct. 16, 1900. C. W. Arra-
smith, Courtland, Cal. This invention is
designed to provide a means for packing
fresh fruit rapidly into baskets, or similar
receptacles, and to provide for a suitable
convexity or crown to the surface of the
fruit. It consists of a baseboard having a
concaved depression and means for sup-
porting the basket inverted over this de-
pression. The bottom of the basket being
opened, fruit is filled into it from the bot-
tom, and when full a flexible covering or
bottom is placed upon it and pasted or
otherwise sealed upon the sides of the bas-
ket which is then inverted so as to be right
side up when removed. The basket is
held in place by spring-pressed arms which
retain it while being filled, and which are
disengaged to allow the basket to be re-
leased. When the basket is removed the
baseboard and the basket are turned to-
gether so that the latter is in its proper
upright position.
Latest flarket Reports.
San Francisco, Oct. 25, 1900.
SILVER— Per oz., Troy: London, 30Jd
(standard ounce, 925 fine); New York, bar
silver, 65Jc (1000 fine) ; San Francisco,
65 Jc; Mexican dollars, 51 }c.
The combination of Indian and Chinese
demands makes it likely that the improve-
ment in the market for silver may con-
tinue, as there is prospect of , further pur-
chases of bar silver in the London market
or elsewhere for the Indian Government,
to he used in the coinage of rupees. Good
crops in India and large exports during
the ensuing year may give that country a
favorable balance of trade, which would
have to be settled in silver. Conditions of
this character, moreover, would naturally
create a demand for additional silver
money for circulation in India, and it is
therefore thought that the Indian pur-
chases of silver during the next twelve
months are likely to be larger than in any
corresponding period since the closing of
the mints of that country to the free coin-
age of silver. With favorable internal
conditions India seems, in fact, likely to
require and to buy as much silver each
year as it did prior to the suspension of
free coinage, and such demand, if kept up
and not accompanied by considerable in-
crease in the current supply of silver,
would probably lead to higher average
prices for silver than have prevailed since
1893.
The demand for Mexican silver pesos
in the East is increasing, says Director of
the Mint Leandro Fernandez, but the pro-
duction of silver in that country is not
commensurate with the increasing de-
mand. He has heard nothing of the pro-
posed abolition of the mint dues to induce
producers to keep silver there. The meas-
ure, he declares, is not likely to be pushed
at present. The smelters are shipping a
large portion of their output to the United
States, even paying the 5% export tax,
thereby saving the charges for coinage
established under the Mexican law of 1897.
This law levies a coinage duty of 2% and
a stamp duty of 3%. The pending elec-
tions in the United States have affected
foreign exchange in Mexico. Four years
ago gold exchange fell to 180. Last April
the exchange reached 210. It is now 198,
with a tendency to reach a rate lower
than that prevailing in the fall of 1896.
The production of silver in Mexico is ham-
pered by local conditions, such as lack of
water at Pachuaca and Zacatecas, and is
not likely to increase materially unless an
appreciation in the value of silver can
make possible the working of low-grade
ores from Chihuahua and elsewhere.

The increase in the business of manufacturing
electrical appliances in this country is illustrated by
the growth of the export trade. During the first
eight months of 1898 the United States exported
electrical machinery to the value of $1,439,743 ; dur-
ing the corresponding period of 1899, $1,828,048 ; and
during the first eight months of the present year the
exports have increased in value to an aggregate of
$3,590,419.
At a recent meeting of the Southwest Miners' As-
sociation at Los Angeles, Cal., resolutions were
adopted setting forth the value to the mining indus-
try of the topographic, geological and hydrographic
work of the TJ. S. Geological Survey, the small
amount of the annual funds available therefor, the
consequent need of larger federal appropriation,
and urging that the States and Territories inter-
ested make effort through their officials and Con-
gressmen to secure larger federal allotments for
such purpose.
It is to the advertisers in this paper that its ef-
ficiency is largely due. Were it not for their pat-
ronage this paper could not be weekly furnished as it
is for less than 6 cents per number. It is, of course,
because of the thousands of probable customers
among our readers throughout the west half of
America that so many firms have their business an-
nouncements in our advertising columns, and it is
because of both facts cited that suggestion is made
that whenever our readers make purchases they buy
of those whose advertisements they see herein.
Gold is constant at $20.67 per ounce, but other
metals are appreciating in value. Silver is steadily
appreciating, and may close the year at a figure
higher than it has been since 1896. Copper in that
year was worth but 10 cents and lead 2| cents. The
present prices make a silver-lead-copper ore of
greater value than at any time since 1893. It is a
noticeable fact that when silver goes up, ordinarily
lead and copper drop, and when silver goes down the
two base metals appreciate in value. The copper
production of the country is in a particularly pros-
perous condition. The copper product for the first
ten months of the year aggregated 4,950,000,000
pounds, valued at about $80,000,000; figuring 8 cents
per pound for all expenses, would leave a profit or
net earning so far this year of $40,000,000. The
Calumet & Hecla of Michigan pays 8.1 cents per
pound produced profit; the Boston & Montana of
Montana, 9 cents; the Quincy M. Co. of Michigan,
about 6.7 cents per pound.
A Proud Record.
The California Miners' Association will hold its
ninth annual session on the 19th inst. It is an organ-
ization that has done a great deal of good, has been
of inestimable value to California's mining industry,
and is not generally credited with its deserts. If it
does not receive the praise it deserves it might at
least be spared some of the unfair criticism bestowed
upon it. It is not pleasant to those acquainted with
the facts to read in a Shasta county paper that the
California Miners' Association is too busy taking care
of the hydraulic miners' interests to give any atten-
tion to northern California ; to read in a Placer
county paper that the California Miners' Association
neglects the hydraulic miners and devotes too much
attention to other sections ; to read in a San Fran-
cisco paper that politics enters into its purposes, or
to read in a Los Angeles paper that southern Cali-
fornia is not in its purview. Probably the State is
too big ; perhaps each mining district or even each
mine would do better to have a little association of
its own. But, as Fred Zeitler of Nevada county said
at the last convention, "in union is strength," and
the remark is quoted because it can not be improved.
The California Miners' Association has been extraor-
dinarily fortunate in having been able since its organ-
ization to command the splendid services of men who
freely gave their time and experience to the common
good, bestowing effort that, like many of the best
things of life, could not be paid for in money. Were
all the service so freely devoted to the association
charged for, it would have bankrupted any treasury.
As it was and as it is, anyone serving the association
has been proud to place such service at the call of
the committees, and thus, so far as in him lay, to
advance and aid the cause of the California miner. It
is but due to those men that this be said, and it is
but the simple truth that is here stated.
It is unique in the history of mining in any State
that for nine years men in every walk of life, unawed
by influence and unbribed by gain, men the value of
whose hours are counted in dollars, should have given
gratuitously of their time and effort in successful
advancement of the mining industry, no officer or
member drawing a dollar in salary.
If it be deemed advisable to descend from so high a
plane ; if it be considered of greater good to split up
and stray into little sectional coteries ; if such seces-
sion conduce to greater value to the mining industry
of the State, then perhaps it were well to give such
idea consideration. But if the same spirit shall pre-
vail that pervades and animates such organizations
everywhere, the spirit of union and solidarity, then
it were well not to be too hasty in condemning a
result not wholly understood, and to stand by the
only organization of the kind that has been run with
such singleness of aim, such loftiness of purpose and
such successful result to the general mining prosper-
ity of the commonwealth.
1 ' Why is not more said about revision of mining
laws and a department of mines and mining in your
columns ? " asks a Utah subscriber. There are sev-
eral reasons why ; the principal one is that no public
journal can afford to keep talking of one thing con-
tinuously. This paper originated the ideas, advo-
cated them, got them indorsed, and so did its duty
in advancing the interests of the industry it repre-
sents, but it is neither our province nor our purpose
to weary our readers with any subject, however im-
portant it may be. Besides, it argues a poverty of
mental resources to be always talking about the same
thing; there are other topics of equal present im-
portance to be discussed. Then, too, this paper has
no special personal interests to serve. Meanwhile,
whenever the American miner makes up his mind he
needs those things he will have them. It would be
worth $100,000,000 annually to the mining men of
this nation to have proper revision of the mining
laws and a department of mines and mining, with a
cabinet officer. The need for both of these things is
even greater than when this paper began their ad-
vocacy years ago. It is a national loss that the
great basic industry of the nation is so unrepre-
sented, and that the rights of miners should continue
to be at the mercy of some little hundred-dollar-a-
month clerk in Washington, who can make more con-
tradictory rulings in a week than can be straightened
out in a year. The only present suggestion that oc-
curs to us is for mining men everywhere to show the
power of their votes and require from Congressmen
pledges of support to these measures, and of legisla-
tive candidates that they shall require from senato-
rial candidates satisfactory assurance that they will
advocate these most necessary measures.
A Standard Necessary.
The need of an American Standardizing Bureau is
manifest to all who have the advancement of science
at heart, and it is hoped that during the coming ses-
sion of Congress a bill authorizing the establishment
of such a bureau will be passed. A bill for this pur-
pose was introduced last winter and was favorably "
reported by the House committee having it in
charge; the Senate committee on commerce, how-
ever, failed to give it consideration. Its present
necessity arises principally from the electrical field.
In the latter, while there is a standard volt and a
standard ampere (although not fixed by law), we
have no one standard for the unit of resistance —
the ohm. An editorial in the issue of March 10th
pointed out that there are at the present time
four standards for the ohm extant, namely, the
"legal" ohm, the " British A ssociation " or " B. A."
ohm, the " International" ohm, and the "Siemen's"
ohm.
The "legal "ohm, adopted at Paris in 1884, was
made equal to the resistance offered to flow of elec-
tricity (unit flow under unit pressure) by a column of
mercury one square millimeter (0.03937 inch, or a
small fraction less than -j^ inch) in section and 106
centimeters (0.4173+ inch) in length, the tempera-,
ture being at the freezing point (32° P. or 0° C.) and
the pressure of the air being equal to the pressure
at the base of a column of mercury 760 millimeters
(30 inches) in height. The other units differ from the
" legal " ohm only in the matter of length of mercury
column, so that in the adoption of a standard ohm
the only thing necessary would be to fix upon some
uniform and universal standard of length for the lat-
ter. In the matter of " candle power " also there is
no standard.
The main thing, however, is to adopt invariable
standards for the volt, ampere and the ohm, and
when this is done the determination of other stand-
ards will be made easy.
Gold dredging is proving to be a profitable form
of gold mining in California as elsewhere, but ex-
travagant statements are being made regarding the
possible returns. The truth is good enough without •
exaggeration. A prominent dredger operator states
that with his dredger in the last year he handled 320,-
000 cubic yards of material, which averaged 15 cents
per cubic yard, at a total cost of 5 cents per cubic
yard. This last item included every detail of expense,
including interest on the amount invested. This, in
round numbers, would mean the handling of 1000
cubic yards per day, at a daily net profit of $100,
which is a fair average statement of results, and in
this case a truthful one. Dredging is yet an evolu-
tionary form of mining. Its origin was in New
Zealand, in 1869, where the first dredging apparatus
is described as having consisted of "a strong iron
ring, technically known as a ' spoon, ' to which was
secured an ox-hide bag and a long pole. A rope was
fastened to the iron ring and secured to a hand winch
on the bank of the river. The bucket and pole were
taken out and dropped into the stream by means of
a boat, the bucket being pressed by the pole as deep
as possible into the wash in the bed of the river."
The bucket was then hauled ashore by the winch,
and the contents put through a California cradle.
The process from such primitive device to the $45,000
gold dredger of 1900, operated by electricity, illus-
trates mining and scientific advance.
Commenting on editorial reference herein in the
issue of the 20th ult. , to the projected absorption of
the Guggenheim smelting interests by the American
Smelting & Refining Co., several contemporaries
have stated that "this will leave the trust in su-
preme control of all the smelting business of the
mining States." The remark does not apply to the
Pacific coast, where several large smelting estab-
lishments are in active operation entirely independ-
ent of any combination.

ANY speed is "dangerous" if the vehicle can not be
stopped in a short space. An engine going 5 miles an
hour is as dangerous as if it were going 50 miles an hour
if the object is so near that the engine or vehicle can not
be checked in speed. The question of speed is really one
of brakes.
It is difficult at any time, and ordinarily impossible, to
name "the best" of any device. It can not be stated
what is "the best" pump, though one may have his
preference. Any pump well made by a man who has ex-
perience and intelligence would give good work under
certain conditions and requirements.
The simplest arrangement for parting silver buttons is
a sand bath, upon which may be placed glass mattrasses
containing nitric acid, the sand bath being placed upon a
furnace until the acid is hot, then drop in the buttons
and boil ten or fifteen minutes. Either Chapman's or
Richard's filtering pumps are efficient.
Gas engines may be divided, generally, into two
classes — those effecting combustion at constant volume,
and those necuring that result at constant pressure. The

Geo. P. Becker of the U. S. Geological Survey says :
"In such rocks as I have Been in tho quicksilver mines
of California wide simple fissure veins are not to be ex-
pected at any level, and irregular chambers are not so
likely to be met with at great depths as at small ones,
though they may occasionally be found at any distance
from the surface."
The Frue is a good typo of the vanner ; the Willley,
of the riffle washer. The whole matter of concentra-
tion has as its basis the attribute of specific gravity,
and, like nearly everything else connected with ore treat-
ment, the quality of the ore and the surrounding cir-
cumstances must determine the manner of treatment in
each individual case.
To prevent the piracy of foreign copyists of Ameri-
can inventions "design patents" may be secured in
foreign countries where patents are issued ; or, a trade
mark or a trade name may be adopted, registered in the
U. S. Patent Office, and then registered with such for-
eign countries as have treaty relations with this country
concerning trade marks.
The arrangement with the cyanide patentees made by
the Australian and New Zealand governments, respect-
ively, was the same in both cases — the government
bought all existing agreements for a lump sura of
$100,000. Tho government royalty for use of the pat-
ent by cyaniders is 2J% till the purchase money is re-
paid, when further charge will cease.
A good steam motor or "automobile " should be had
for about $600; one in which gasoline furnishes the
power, $1000; an electromobile, $1500. A gasoline auto-
mobile in some respects is preferable, and gives more
power from a definite quantity of fuel than either of the
other types. Automobiles are in use in San Francisco
capable of going from that city to Los Angeles — 600
miles.
True " slimes " consist of the argillaceous portion of
the ore existing in it, either as infiltrated clay, or as
kaolin from the kaolinization of feldspars, or as hydrous
magnesian silicates. This material is best separated
from the granular part of the crushed ore by hydraulic
classifiers. So long as the particles are granular, no
matter how fine, they can be economically treated by
leaching.
Losers of money in silly oil and copper investments
have none but themselves to blame. Making inquiry
after the event is in a line with such folly. A little care-
ful inquiry before the investment would save such loss.
Usually stock in a mining company is of value directly
proportionate with the urgency displayed in offering it
to the public — the more urgent the offer the less value to
the proffered stock.
The advantages of a Cornish pump are that it does
good work, works well with clean or dirty water, and is
so simple that almost any one can attend to it after a
little practice. It requires little attention except to
change the buckets, clocks, etc. Among its disad-
vantages are that it takes up considerable room in a
shaft, it will not work economically with a throw of more
than 250 feet and is of relatively great weight.
Even the meager $100 of annual "assessment work"
on an unpatented mining claim' is sometimes squandered
and valueless when done with the idea that it is a sort of
irksome Government tax to be perfunctorily performed
"to hold the claim," being thus often done not where it
would do the most good but where it can be done most
easily. The true object of annual assessment work is to
develop the property in the best interests of its locator,
and thus add to its value.
FOR the treatment of cupriferous ores and concen-
trates which.-could not be treated successfully by ordi-
nary cyaniding, Park and others claim to have obtained
satisfactory results by first subjecting the ore to a
chloridizing roast, and then leaching out the copper
chlorides with water. After an alkaline and water wash
the gold and silver contents were extracted by cyanide
by percolation. During the roasting the silver sulphides
present were chloridized to the chloride, which was then
dissolved by cyanide.
The law of Mexico prevents private ownership of
mines by either native or foreigner. All mines belong to
the Government, and the men or companies which work
them do so by paying for a concession, and then paying
a tax on the output. Anybody can get a concession if
they can find one that is vacated. The holder must keep
at least four men at work in useful employment about
the mining plant. If he neglects to do so for a period of
sixty days he may be denounced, and the denouncer can
obtain the concession if he will begin work within sixty
Silver in all its forms requires a stronger solution of
cyanide to effect its solution than gold, and occasionally
the large relative consumption of cyanide is due to the
presence of silver sulphide— Ag2S. The potassium sul-
phide resulting from the dissolution of silver sulphide
also occasions a loss of cyanide. A trace of alkaline
sulphide in cyanide solution does not act injuriously, but
an appreciable quantity causes the precipitation of a por-
tion of the dissolved gold in the vats. Some considerable
percentage of this precipitated gold is redissolved by the
excess of free cyanide present in the solutions, but in
such cases as that under discussion it always requires this
excess to obtain adequate extractions, thus necessitating
the use of comparatively strong solutions.
A Reno, Nevada, man asks: "Will you please in-
form me whether an ore containing a large percentage
of black oxide of manganese has a market value ?" This
question is published to illustrate a usual mistake, viz.,
not giving sufficient data to permit intelligent answer.
If the ore is a manganiferous iron ore, containing at
least 6% to 8% of manganese, it would have a commercial
value as a flux in silver-lead smelting. It might also
have a value for steel makers; but, as the Reno inquirer
does not state what the other constituents of the ore are,
it is impossible to fully answer his question.
He is not entitled to a patent who suggested the in-
vention in dispute and made an experiment on a small
scale, but did no more till another had devised it, ob-
tained a patent and begun the manufacture. All inven-
tions which are patented must be marked "Patented,"
together with the day and year upon which the patent
was issued. In case of failure to comply with this law no
damages can be collected. He is the real inventor, and
entitled to a patent, who first makes a machine capable
of useful operation, though others may have previously
conceived the idea and made experiments toward put-
ting it into practice.
To extract the fragment of a drill, punch or other
steel tool which has broken off while working any metal
but iron or steel, the object containing the broken-off
piece is immersed in a boiling solution composed of one
part commercial alum to four or five parts water. This
solution may be held in a vessel of stoneware, porcelain,
copper, etc., but not of iron. The object should be so
placed that the gaseous bubbles that form as the alum
attacks the metal are easily disengaged. At the end of a
short time the fragment of the tool is entirely dissolved.
A piece of a steel spring .16 inch thick is dissolved in a
concentrated solution of alum in three-quarters of an
hour.
There is nothing illegitimate in bona fide sale or pur-
chase of regularly issued stock in any legitimate enter-
prise, nor is there, necessarily, any more of a "gamble"
in mining stock than in any other kind of stock rightly
valued. As with a mine, so with a railroad or a bank or
a factory. One could not well cut up the railroad or
mine or factory into little bits and sell it in minute sec-
tions; but bits of paper called "stock certificates" can
be issued, bought and sold, representing the tangible
property, shares in which are thus susceptible of trans-
fer. The owner of any number of shares owns just that
percentage of the property so represented, and it is just
as legitimate to buy or sell such shares as to buy or sell
the property itself.
In the electrolytic extraction of quicksilver from cin-
nabar the raw material is crushed to a fine powder, and
then treated with a hot solution of sodium-sulphide con-
taining caustic soda. The electrolytic vats are of iron,
and may be used as cathodes ; the anodes are of sheet
steel. It is stated that the mercury can be readily sepa-
rated from the upper part of the cell, and is enriched
with equivalent amounts of copper, silver, zinc, cad-
mium, nickel and iron in the lower or anodic compart-
ment of the cell. The solution on issuing from the cell
is then passed through a series of vessels, in which the
silver is displaced by copper by simple chemical action.
Copper equal to about one-fourteenth of the weight of
the alloy used has to be consumed in these in order to
effect the desired precipitation of the silver. It is not
possible to remove the last traces of silver by this
method, but the amount found in the deposited copper
should not exceed 0.3% when the process is working sat-
isfactorily. After passing through a series of the sul-
phide solution, by using a current density of 0.5-0.8 am-
pere per square decimeter and an E. M. F. of two volts
the electrolyte can be used again for extracting fresh ore
after addition of sulphur.
In the issue of Oct. 6th a method was given of making
sodium amalgam. Wm. Crookes, the inventor of the
alloy, has furnished more detailed directions as to its
preparation. The mixture of sodium and mercury is in
the proportion of three parts of sodium to ninety-seven
parts of mercury. " Place a strong iron flask with a
narrow neck nearly up to the mouth in sand on a sand
bath kept at a temperature of about 300° F., weigh out
the mercury and sodium, and put the former into a
flask, and then add the sodium in pieces as large as a pea
at a time, waiting for the action to cease before adding a
fresh lump. The sodium had better be dropped in with
a pair of tongs, and the hand should have a cloth over
it. At each addition of the sodium a slight explosion is
heard and a bright flame will issue from the mouth of
the flask. The action gets less violent as the mercury
becomes richer in sodium. When the whole of the
sodium has been added, pour the amalgam into a flat
dish while still liquid, and when cold break it up and
preserve in a stoppered jar. It will not require to be
kept under naphtha. The amalgam forms a mass of
long, needle-shaped, brilliantly metallic crystals, which
interlace in every direction, but have very little cohe-
sion." The inventor recommends the use of the amal-
gam in coarse powder. By sprinkling it over the wetted
surface to be amalgamated, then rubbing it over with a
little clean mercury, a firmly adherent and brilliant coat-
ing of mercury will be given to the metal. The use of
sodium amalgam has a tendency to keep the mercury
bright and active, but it cannot be expected to perform
any other part in the extraction of gold than in aiding
amalgamation.

Machine Mine Rock Drills on the
Pacific Coast.

The Band.
Iugersoll and
Sergeant
drills have
been in suc-
cessful use
for so many
years, both in
this and other
countries, aud
are in conse-
quence so well
known, that a
brief descrip-
tion of these
machines will
serve the pur-
pose of this
article.
The accom-
panying illus-
trations rep-
resent the lat-
est forms in
which they are found on the Pacific coast.
Each one of these rock drills is typical of a distinct
class of valve motion, the Eand having a slide valve
positively operated by the main piston through a
tappet. The movement of the piston valve in the
Iugersoll is controlled by the main piston, which cov-
ers and uncovers at the proper time the aperture of
posts leading to both ends of the valve chest respect-
ively (Eclipse type).
in the Sergeant drill the piston valve is also oper-
ated by pressure, regulated by a curvilinear auxil-
iary valve, shifted back aud forth by contact with the
main piston. In all of them the latter is recessed,
and carries at its rear end a nut, engaging a rifle
bar which imparts to the piston and its rod a twist-
ing motion, by means of a ratchet gear. In the Iu-
gersoll aud the Sergeant drills the ratchet head is
turned smooth, aud carries some swiugiug pawls,
which eugage the teeth of a stationary ring in the
ratchet box. while in the Eand drill the ratchet head
carries the teeth, and turns agaiust stationary-
pawls.
In all these machines the feed is effected bv hand.
at least for underground work,
and flat or spiral spring buffers
are located at the back end
of the cylinder.
The shells are secured to the
clamps by a conical heel, with
the larger base outward in all
of them.
Two distinct types of rock
drills are manufactured by the
Eand drill firm, and, while quite
similar in many points, they
differ in the arrangement of
their valve motion. One of
them, known as "Little Giant,"
may be characterized as follows:
Valve motion : Tappet oper-
ating a slide valve from under-
neath. This arrangement has
been reproduced in the Giant
drills of local make, previously
described.
Rotary motion : Fixed pawls,
movable ratchet head.
Feed : Hand.
The other type of Eand drill,
known as the "Slugger," is
characterized by the following
features :
Valve motion': Balanced cyl-
indrical valve, Eclipse type. It
will be remembered that this
appellation is merely' intended
to designate a piston valve
operated by pressure, through
the uncovering or closing of
appropriate passages by the
main piston of the drill.
These ports operate the valve
by closing in the latter types of
the Slugger, while they accom-
plish the same object by opening
in some previous designs.
The momeutum of the piston
on the back stroke is checked
by cushioning in all machines of
this variety, but this is effected
by a premature closing of the
exhaust in some machines, and
by a convenient amount of lead
in others.
One distinctive feature of
this type is the possibility
of adjusting the point of cut-
off so as to work expansively.
The Rand Drill.
Eotary motion: Stationary pawls
and movable ratchet head.
Feed : Hand.
Several patented devices are
found, namely, in the piston rod and
chuck, in the attachment of the rifle
to the ratchet and to the back
head, in the split crank and feed
nuts, in the adjustable shell slides,
and in the throttles. These points
can only be mentioned in this brief
review.
Some intermediate varieties of
Eand drills are found in the market,
combining the salient features of the
two types just described. Such is
the "Little Terror." which has a
piston valve* in the exhaust nozzle,
to vary the length of stroke when
starting a hole.
All these machines can be operated
by steam or compressed air at will,
the change involving only a differ-
ence in the quality of stuffing-box
packing.
The clamp used to secure the
shell to a tripod or to a shaft bar or
arm operates, in principle, by hold-
ing the boss of the shell with a
movable dovetailed hook, secured in
position by a nut.
* Operated by tappet and a restrictive valve.

The Ingersoll-Sergeant Drill.
New Concentration Method.
At a new tailings plant just erected at Kellogg,
Idaho, it is intended to give practical test to what
is considered a new principle in concentration of ore.
The idea in practice is a movable table with either a
wooden or a metal top, covered with a screen of wire
or cloth, the latter being considered by the inventor
preferable for very fine pulp. The feed runs onto the
top of the screen while clean water is fed on the table
from the sides, entering below the screen. The table
is then given a reciprocating motion, the stroke being
given by a cam while the return depends on springs.
The quicker stroke of the cam forces the metals to
the high end of the table, as in the bumper concen-
trator, while the water and lighter waste runs off at
the lower end. The tables can be made any size, but

those in use are 39 inches wide by 8 feet long, and the
stroke can be made of any length required, depend-
ing on the weight of the metal being saved.
The water running directly onto the table below
the screen has a free outlet , but the screen, instead
of sagging beneath the weight of the feed on top,
begins to rise in the middle as soon as the machine
starts. Onto that the feed runs, the finer parts work-
ing down through the screen onto the table while the
coarser runs off on top of the screen. The metal
works to the high end of the table along the edges,
while the waste is carried off. The metal which
passes through the screen onto the table is forced
back through it again when it approaches the high
end of the table and follows the end of the canvas
screen down to the settling tank under the table.
It is desirable that the pulp should be reasonably
even. The manufacturers say that by the use of
screens of different sizes any size pulp from two to
eighty mesh may be bandied, and a complete plant
would carry tables with different screens, while a
classifier would separate the feed into grades of the
same coarseness. The motion of the machine makes
the top of the water take a wave form, one wave
pursuing another continually, and the rolling motion
thus given the surface carries the floating particles
down, and, once submerged, it is claimed that they

A Labor-Saving Device.
In mining and metallurgical work the present con-
stant effort is to reduce cost of operation. So
effective is thus tendency that in many instances the
cost is less than one-balf what it was ten years
ago.
More especially is this ever-present effort at

which is not very hot. A heat of about 700° F. is
needed in the hottest part of the furnace, which is at
contact with the fires, the mercury becoming vapor
between 600° and 700°. The tiring is done with wood,
it being cheaper than coal in California. With some
of the ores little wood is needed, as the sulphur in
the ore when burning maintains nearly enough heat
to reduce the quicksilver. The discharging of the
roasted or burned ore occurs at the same regular
intervals as charging, so that an even quantity of
ore is constantly exposed to the fires for about thirty
hours. The entire fumes from the furnace, consist-
ing of mercury, petroleum, wood oils, creosote, sul-
phur, acids and water, are carried through tight
flues into condensers, either built of brick with many
compartments or of cast iron connected by flues,
from which perhaps 60% of the mercury will flow into
catch basins. The residue is called soot and contains
mercury, charcoal (wood ashes), oil, sulphur, salt,
etc. This residue is first treated with a bath of
strong alkali to remove oil and grease, then mixed
with four times its bulk of quicklime, which is allowed
to slack in contact with the soot. It is then put into
shallow iron pans and charged into cast iron retorts
which hold from 600 to 700 pounds. This is treated
at a low red heat for twelve hours, when no mercury
should be left in the residue. From the retort there
is an exit pipe, which is water jacketed, through
which the fumes pass and are recondensed. The mer-
cury is recovered in a pure stale and is put into
wrought iron bottles or flasks containing 765 pounds
(a Spanish measure) and shipped to market.
There is little danger, ordinarily, of the miners
getting salivated. If the mechanical condition of the
furnace, draught and condensers is good, and no
leaks are allowed, there is no danger at the furnace.
White men have charge of the furnaces, but consid-
erable of the work of handling ores, soot and quick-
silver at the furnaces is done by Chinese.
Ores of mercury containing one-half of 1% mercury
can be treated at a profit. Its uses are for plating,
for making Chinese vermilion, for medicines, as calo-
mel and other preparations, for making fulminate of
mercury, the high explosive used in Giant caps and
other detonators, and for amalgamating gold, silver
and copper in quartz mills and placer sluices.

Nome and Northern Alaska.
Written by a Returned Prospector.
While the Nome rush, on the whole, was a failure,
it is manifestly unfair to condemn the region on that
score, as several things conduced to that result.
Although too much stress was laid, upon the beach
diggings, the latter, undoubtedly, drew the majority
of those who went to Nome this spring, and the fact
that it would play out was not figured upon. The
beach was worked until late in December, 1899, and
again early this spring; consequently, there was lit
tie left for the vast majority of new comers, a great
many of whom were inexperienced and unprepared
for such an emergency. As a result, "cold feet"
became prevalent and demoralization generally en-
sued.
Those who had arrived a short time before with
high hopes, returned to the States with those hopes
shattered and thoroughly disgusted with the re-
gion.
Outfits on all sides were sold and prices nearly
touched bedrock. To those who went up to prospect
and locate river and creek claims, additional diffi-
culties presented when it was found that the whole
country within a radius of from 150 to 200 miles from
Nome had been staked during last winter.
Notwithstanding these drawbacks, considerable
prospecting and new work were done during the
season.
While results so far, outside of Snow Gulch, Anvil
and Dexter creeks, in the Nome district, and at Tap-
kok, in the Bonanza district, have not been phenom-
enal, they have been sufficient to show that there is
gold in paying quantities in the region, which, when
litigation is settled and things are put on a sound
basis, may turn out to be a large producer.
Golovin Bat District, Alaska. — The Golovin
Bay district, comprising the Inland, Big Four, El
Dorado, Discovery and Blake mining districts (now
merged into one, with recording office at Council
City), is drained by the Fish, Keuchablock, Neukluk
and Casa de Paga rivers and tributaries. Mining op-
erations have been carried on principally around
Council City (now called Golovin City), for the past
two or three seasons. This season principal work
was done on Willow, Ruby and Banner creeks, in In-
land district; on Dixon creek, Big Four district ; on
Ophir, Sweetcake, Elkhorn, Warm and Crooked
creeks, in El Dorado district, and on Melsing creek,
in Discovery district. Results were good — yield aver-
aging about $30 to the shovel per day.
Ophir and Sweetcake are the banner creeks to
date, some of the cleanups having run from thirty to
forty pounds this season.
A two days' run on Ruby returned $400, four men

The Ruins of JTitla, Mexico.*
Written for the mining and Scientific Press.
Oaxaca, Mexico, is not only a rich country from a
mineral standpoint, but is one of the most attractive
to the tourist. In the valley of Tlacolula, 20 miles
southeast of the city of Oaxaca, are to be found the
ruins of Mitla, looked upon by all scientists who have
visited them as the crowning achievement of an
ancient and vanished people. Just when Mitla was
built or by whom nobody knows. The ruins were dis-
covered by the Spaniards who invaded Mexico in 1521,
when all records found were destroyed. They are
now just as they were then ; 379 years has not made
the slightest change. The building of the Mitla had
its birth so far back in the twilight of time - that
naught but tradition remains. Among the Indians
who inhabit the hamlets adjacent to the ruins tra-
ditions are rife. The inhabitants of these villages
are descendants of the Zapotec Indians, and they
claim that at one they were a great and powerful
people, and that Mitla was the dwelling and burial
place of the Zapotec kings.
The ruins of Mitla are peculiar to themselves, being
of stone ; they partake of no known civilization and
have no likeness either to the ruins of Yucatan,
which lie to the northeast, or of those in central
Mexico, lying to the northwest. Situated as they
are between these historic points, it is supposed by
some to be a connecting link. Travelers and ex-
plorers who have visited all these old relics of by-gone
days, and have spent weeks and months in their
study, find that Mitla stands alone, conspicuous for
its singularities of architecture. . and ornamenta-
tion.
Bancroft, the eminent antiquarian, says in " Native
Races of the Pacific Coast : " " Mitla is probably
the finest group in the whole Mexican territory.
Here was a great religious center, mentioned in the
traditional annals of the Zapotecs, the original name
of which seems to have been Lioba, or Loba, the
place of tombs ; called by the Aztecs Miquitlan,
Mictlan or Mitla, (place of sadness), dwelling of the
dead, often used in the sense of hell. The gloomy
aspect of the location accords well with the dread
significance of the same. A stream with parched and
shaded banks flows through the valley ; no birds sing
or flowers bloom over the remains of the Zapotec
heroes."
The ruins are iu five groups; three of them are well
preserved and attract the most attention. One group
is about 120x100 feet, with walls standing 15 to 18
feet high, enclosing a large court, or patio ; around
this patio the walls are laid off in oblong panels, built
in the most unique designs in bas-relief, mosaic in
character. The largest group is about 300 feet long
by 110 feet wide. The walls are about the corre-
sponding height as those described above, and about
6 feet thick. They have the same character of
mosaic decoration, but different in design, each panel
being unlike any other in the ruins. Sculptured col-
umns or frieze are conspicuous by their absence, and
that is one of the marked differences between these
and other ruins in Mexico. The walls of Mitla are
built of a most peculiar design, being formed of small
pieces of stone from 1 to 6 inches in length, 1 inch in
depth and 2 inches in breadth, very accurately cut
and built into the face of .the wall, forming most com-
plicated patterns that baffle description. These
mosaics, all the figures of which are rectangular or
diagonal, give the distinctive character to Mitla that
distinguishes it from all others. The engraving on
the front page, giving the detail of appearance of this
wall, built of mosaic, is the first time any such picture
was ever published.
At Yucatan the hand of the sculptor has left its
impi'int, that has lasted from time immemorial to the
present, and makes them attractive to the tourist,
who makes long pilgrimages to view them. Palenque
is visited by thousands to view the relics of the
ancient sculptor, made famous for its odd designs in
stucco in bas-relief. Copan is visited by scientists,
archaeologists and tourists to study its. idols and
altars — upon the discovery of which and the stu-
pendous work achieved by a people now extinct vol-
umes have been written. But, after a careful study
and investigation of them all, Mitla stands out in bold
relief in the minds of all who visit them.
In 1802 Don Luis Martin and Col. De le Languua
visited these ruins and gave to the world the first

sketch ever made of them, from which the illustra-
tions used in the past have been made. In one of
these ruins is an underground passage or chamber,
and referred to by the guide as the " subterraneo. "
In shape it resembles a cross. Leading from this
passage, somewhere in the ruins, great treasures are
hidden ; and it is claimed that their exact location is
known to one old Indian, who occasionally, when un-
observed by his neighbors, extracts therefrom suf-
ficient to maintain an humble existence. It is also
said that in one of these ruins is a large room filled
with mummified bodies of the Aztec kings. Whether
this be true or not it would be hard to say, but such
explanations from the guide who accompanies all
visitors are not disputed, as it would be in keeping
with the general surroundings, and one feels as
though it were true. Tourists in visiting Mitla in the
past have disfigured the beautiful walls by chipping
off pieces. The Government has taken the matter in
hand, and now no one is allowed to enter the ruins
without a guide, who sees that no further destruction
occurs. The lintels of some of the doorways are of
mammoth blocks of stone, one of which is 19 feet long,
3 feet thick and 6 feet wide. Just how these monster
blocks were raised to their present positions is a
matter of conjecture. Like the massive blocks found
in the pyramids of Egypt, no one can form a theory
that will satisfy the inquiries of to-day as to the
method used.
In one of the large rooms is a long row of columns,
standing in perfect line; these columns are about 14
feet high and 3 feet in diameter, and are peculiar in
themselves, having no base or pedestal, capital or
architrave. In the patio, at the entrance of this
room, stand two of these large columns. In Septem-
ber, 1899, Martin Gonzales, the present Governor of
Oaxaca, removed one of these columns and placed it
in the Passao, to add to the attractive features of
this drive. The removal was accompanied with no
end of objections from the inhabitants of Mitla, and
to maintain order it was necessary for the presence
of a batalion of soldiers under stern leadership to ef-
fect the desired object.
All tourists, are beset by a score of little In-
dian girls offering for sale pieces of Aztec pottery,
faces of idols and beads, said to be found in the ruins
and unearthed during the excavations done there
some years ago under '■ permission from President
Diaz. It is remarkable how keen the sense of busi-
ness is in. these forlorn Indian children, who evade
close questioning as to where they were found or how
they .came into their possession, as nothing that
would lead one to believe they were genuine can be
seen in the surroundings ; nowhere is there the sem-
blance of the handiwork of the sculptor to be found
in these vast ruins; which makes it suspicious. These
articles are often bought by visitors as mementoes of
the trip, regardless of their genuineness as antique
relics. _
Raw Hide Gears and Pinions.
The New Process Raw Hide Co. of Syracuse, New
York, are the patentees and sole manufacturers of
new process raw hide noiseless, solid raw hide spur,
bevel and friction gears, bushings, washers, bound
mallets, etc., their goods being the result of ten
years of experience and experiment. To any one
having use for their products the illustrations on the
front page are of interest. Fig. 1 represents a raw
hide spur pinion, complete, which the makers claim
is "so made as to wear as long as metal or any other
composition now known." It is noiseless — a special
feature in their gear. Fig. 2 is of a solid raw hide
blank, for those who prefer to cut their own raw hide
gears. Fig. 3 portrays the largest raw hide gear
wheel yet made, 33J inches pitch diameter, iron
shrouds and center. Fig. 4 shows a pair of 19-inch
bevel wheels, one of new process raw hide, the other
of cast iron, made for the U. S. Government. Fig. 5
illustrates a number of large spur and bevel pinions
which the New Process Raw Hide Co. of Syracuse,
New York, recently made for one of their customers.
Most of these, it will be noted, are made with iron
centers, a form of construction which they adopt for
gears of large size. In mining and electrical opera-
tions these goods are of value, and any one inter-
ested can have full particulars and testimonials from
pleased customers on application.
In a recent issue was noted the rise in the price of
the " diamonds " used in diamond drills. Such rise
is occasioned by increase in the demand and decrease
in the supply. A drought in the province of Bahia,
Brazil, caused paralysis of the industry there. It is
probable that there will be a further rise, and dia-
mond drill manufacturers have been trying to find a
substitute for the expensive carbons.
At the Paris Exposition the mill engine is not in
evidence, and appears to be ceasing to exist on the
continent. There is not a main driving belt nor a
driving rope at work in the Exposition. All the
large engines, without exception, are employed in
driving dynamos, for the most part of the flywheel
types, and these supply power where it is wanted
through cables led in various directions.
The cost of electrical power in large Philadelphia
machine shops averages 1.2% of the shop pay roll.

How to Build Good Roads.
In the issue of the 20th ult. appeared
an editorial on the necessity for good
roads as a business investment in min-
ing districts. A California county super-
visor in a discussion on that subject
says :
In building a road the first thing to
be considered is its location, a mis-
take in locating a road may cost the
taxpayers large sums of money and
never get a satisfactory road. I hope-
this discussion will lead to broader
views on the subject.
I think we are sometimes so anxious
to have the road located where it will
benefit us most at present, or do us the
least damage, that we overlook the
importance of .locating it on the
best ground. Some one has said that
no ground is too good for a road. As a
result of mistakes in locating roads
we have now in the fourth road
district in my county (San Diego)
three roads leading to Palomar moun-
tain, or rather from the base to the
top of the mountain, two of which ought
to be vacated ; one to the Escondido
reservoir, one to Guejito and two out
of the San Pasqual valley ought also to
be vacated. The cost of these grades
must have been thousands of dollars,
but they are so steep and narrow as to
render them dangerous. I think the
people ought to get together and co-
operate to get the road in the best
place.
Those steep grades before mentioned
are not oited to find fault with any of
my predecessors, for I do not know who
built them ; it is roads we are discuss-
ing, not men. There is one thing evident
to me, that is, we have too many roads
or not enough money, I suppose both
are true.
In my opinion we should have a law
classifying the roads into three classes.
Class one should be State roads, built
and kept in repair with State funds.
Class two should be county roads, built
and kept in repair by a tax levied on all
the property of the county. Class
three should be district or neighborhood
roads, built and kept in repair by a
direct tax levied on the property of the
district and a road poll tax which may
be worked out if preferred. Class one
should be under the supervision of the
county surveyors of the counties
through which they pass. Class two
should be under the supervision of the
board of supervisors, and class three
should be under the management of a
road overseer or some other local man-
agement.
I think there will be no disagreement
as to classes one and three, but there
may be some objection to taxing in-
corporated cities for road purposes.
But I should place the cities in a cata-
logue with districts which must help to
build and keep in repair both State and
county roads, and in addition must
build and care for their own roads. It
would seem but fair that cities should
help in like proportion on the State and
county roads and in addition keep up
their own streets. I think a system of
good roads leading to a' town or city
tends to build up business of all kinds ;
then I believe that it is as much to the
interest of the cities that country peo-
ple should come to their places of busi-
ness as it is important that country
people should have a market and a good
road to get to it. And by thus doing
away with sectionalism, and city and
country uniting heart, hand and purse
we could bring about such a revolution
in road building and care as to result in
great improvement. I feel greatly in-
debted to the cheerful kicker's protest
against present conditions. Continue
still to point out the mistakes and
blunders and " show us the more excel-
lent way."
Returning to the subject of locat-
ing roads, it appears from the rec-
ords that deeds to right of way for
roads had never been recorded until
within the last five years, and in some
instances we have been compelled to
buy the right of way for roads tfhat we
thought the county owned, at least
they had been declared public highways
by the board of supervisors and worked
with public funds, and sometimes we
are obliged to pay an exorbitant price
or enter into an interminable lawsuit to
condemn the right of way. One in-
stance I have in mind, which was be-
gun four or more years ago, was
recently dismissed, and still no road.
Now, in my opinion, there should be a
maximum price established by the Leg-
islature, based upon the assessed valua-
tion of the land (say two or three times
as much as it is assessed for), and the
damage assessed as now by disinterested
appraisers or viewers sworn to faith-
fully and impartially perform their
duty.
Roads have in some instances been
laid out without the least regard for the
necessity for their construction, the
number of people they would accom-
modate, the sums of money they would
cost, or the territory they would
develop.
Considering the subject of funds
for road building, the tax we are
now permitted by law to levy for
road purposes is little more than enough
to keep in repair the roads as they are
now, and to contemplate any radical re-
form or build any Macadams or Telfords
would require funds far in excess of any
sum the board of supervisors has ever
at any one time had its disposal ; hence,
before any of these great improvements
are made there will have to be some
methods adopted to supply more funds.
We have voted bonds in the past upon
which we are still paying interest. I
should certainly not favor bonds until
every other or at least some other plan
had been tried. I think permission
should be granted by the Legislature to
counties to issue scrip, based on the
assessed value, not to exceed 1%.
I am sorry that the Legislature re-
pealed the "wide-tire law." I think it
ought to have been amended so as to
exempt old wagons and refer only to
new wagons and those built or sold in the
State after the law took effect. Ten
States in the Union have at different
times enacted wide- tire laws, and some
of them have been in operation for a
long time, at least long enough to
thoroughly test their utility. I refer
particularly to New York, Ohio, Indi-
ana, Kentucky, Vermont, Michigan,
Pennsylvania, Massachusetts and Cali-
fornia. I admit that there are instances,
perhaps, where a wagon with a wide tire
will draw heavier than one with a nar-
row tire — for instance, where the ground
is soft enough for the wide tire to cut
through; but in all other places, except
those referred to, the wide tire draws
lighter than the narrow. If there
were no difference in this respect the
benefits to the roads are such as to
urge their use. Indiana, Kentucky,
Vermont, Pennsylvania and Massa-
chusetts all make distinction in favor of
the wide tire. Experiments made in
New York are very much in favor of
wide tires. Experiments have been
made in Ohio, Missouri and Vermont,
in each instance with the same re-
sult. Austria, Prance, Germany,
Switzerland and Canada (according to
Consular reports), all favor wide tires,
and some of them have laws enforcing
their use, Prance in particular. I quote
from a report : "Every freighting or
market cart here is a road maker ; its
tires are from 4 to 10 inches wide. With
the few four-wheeled freight vehicles
used the tires are rarely less than 6
inches in width and the rear axle is
about 14 inches longer than the fore, so
that the rear or hind wheels run in a line
an inch outside the level rolled by the
fore wheels." Whether we have a wide-
tire law or not every person ordering a
new wagon should insist on having wide
tires.
E. H. Clear, a New York "pro-
moter," is gravely announced in an
electrical journal as ' ' organizing a
company to operate automobiles along
the Yukon river to convey miners and
machinery to the Klondike." To any-
one with the slightest knowledge of the
facts the statement is ridiculous.
A striking example of the extent of
the advance in prices of iron and steel
last year is afforded by a statement
made in the annual report of the Chi-
cago Great Western Railway for 1899.
It seems that this road has actually ex-
changed old rails for new at a profit.
They purchased 10,000 tons of 75-pound
steel rails at $19 per ton. While they
were being laid and the old ones taken
up the iron market advanced to such
an extent that the old rails were sold
for about $10 per ton more than the
new ones cost.
Artificial Fuel.
Regarding the manufacture of pat-
ent fuel in Wales, U. S. Consul Phillips
can see no reason why a pound of bitu-
minous or anthracite coal dust should
be wasted, nor why the industry should
not succeed in the United States. He
says the agglomite process of manufac-
turing patent fuel from anthracite and
bituminous minerals is entirely different
from any other. By this method the
coal and agglomerates are chemically
mixed while under the influence of heat
and pressure, in a sealed vessel, by
which a new fuel compound is produced.
The process is as follows : The coal and
agglomerates are mixed and ground in
a dry state. If tar or pitch or other
liquid substances are used they may be
subsequently added ; then the prepared
material is put into a hopper attached
to the end of a horizontal tube. The
opposite end of this tube is connected
with a briquette press. A worm is kept
constantly revolving in the tube, con-
veying the material through the tube
and feeding it into the pressing ram
chamber. The tube passes through a
small furnace, which enables the ma-
chine to become heated to a tempera-
ture of 500° or 600° Pahr. The gases
evolved cannot escape, hence the pres-
sure produced within the tube is shown
on an attached gauge to be about ten
pounds per square inch. Practically,
the tube is an automatically sealed ves-
sel, for the closely packed mass of coal
materials fed from the hopper into one
end of the tube by the revolving worm
and the hot plastic mass fed out by the
same worm into the pressing chamber
at the other end of the tube is so
closely blocked up by the passages as
to overcome the internal pressure of
ten pounds per square inch created by
the hot gases. These gases, under
pressure, permeate the hot plastic
mass, which is turned over and over as
it travels slowly along the sealed tube.
Millions of tons of anthracite coal dust
now thrown away can be successfully
utilized in this manner. It will not take
long for our quick-witted Americans to
master details.
Manufacture of Circular Saws.
Circular saws are made of cast steel
specially manufactured for the purpose.
A steel ingot heated to the requisite
temperature is reduced to the proper
thickness in powerful rolls. The plate
is then centered and a circle scribed
upon it, after which it is passed to the
shearer, who reduces it to a circular
form. The center hole is then bored ;
it is handed to the toother, who punches
out the teeth around the edge, after
which they are rough filed or ground
on an emery wheel, to take off the burr
left for punching. The rough saw is
now again heated in a large furnace
until it is of bright red color, then
plunged into a bath of sperm oil, which
makes it hard and brittle. The oil is
then partly cleaned off, and the rest
burnt off in a furnace to give the saw
the required temper. When cold the
saw is hammered on a steel-faced anvil
until it is straight. ' It is next ground
between vertical grindstones revolving
in opposite directions, and then polished
with emery on a large disk. Once more
the hammer men take it and strike it
with smooth-faced hammers on an anvil
as before, until it is absolutely straight
and true and has acquired the proper
tension, which allows for expansion
while the saw is revolving at work.
The teeth are now set, alternately right
and left, to allow for clearances when
sawing timber. They are then sharp-
ened by being filed on the front and
tops of the teeth, which operation com-
pletes the manufacture.
The Sultan of Johore, in the southern
part of the Malay peninsula, has
ordered $750,000 worth of American
electrical machinery.
Rights of Employes to Their Inventions.
By a recent decision of a German
court an employe in that country has
no right to any invention he may make
so long as he remains an employe. The
following statement of the relations be-
tween employers and men in the United
States as regards inventions made by
the latter is of interest :
"In general, the law secures to every
man the ownership of his own inven-
tions and of the patent granted there-
for. But this general principle is much
modified by the special relations exist-
ing between the employe and his em-
ployer in particular cases. A wide
distinction is made between the person
who is employed merely as a skilled
workman and the person who is em-
ployed as an inventor.
"As to the former: If a skilled
workman, while in the employ of an-
other, but in his own time or after
working hours, conceives an invention
and constructs it at his own expense,
using his own tools and materials, and
doing the work after hours or in time
his employer does not pay for, then the
invention, as well as the patent granted
therefor, is the exclusive property of
the workman. The employer has no
rights in it, nor any right to use it in
his business, even though it is adapted
to that business. The employer in this
case can obtain the right to use the in-
vention only by contracting with the
workman for it and paying the price
agreed upon, But if the workman con-
ceives the invention in the time his em-
ployer pays for, and constructs it with
his employer's tools and materials and
in the employer's time, then the em-
ployer obtains certain rights in the in-
vention and patent granted therefor.
1 ' If the invention is a machine, then
the machine belongs to the employer,
and he has a license to use it in his busi-
ness and to keep it in repair, and with-
out paying any royalty to the workman
therefor. If the employe obtains a
patent for the invention and sells it,
that sale will be subject to the license
to the employer, and the purchaser of
the patent cannot prevent the employer
from continuing the use of the machine.
" If the invention is not a machine,
but is an article of manufacture, as a
tool in which the employer deals, then,
in the circumstances supposed, the em-
ployer has a license to make and sell
such tools without paying royalty, even
after the patent is granted, and neither
the inventor nor the purchaser of the
patent can stop him from continuing to
do so. In each case the employer's
license continues over to any corpora-
tion into which the employer's business
is converted.
' ' If the invention is a process, then
the employer, or the corporation which
continues his business, has a license to
use that process without paying roy-
alty, even after the patent is granted
to the workman.
"In these cases, however, the license
to make and sell the machine or the
article and to operate the process is
not exclusive — that is, it does not give
the sole right to the employer ; it only
secures to him a right to the invention
in connection with his particular busi-
ness ; and the inventor, or those to
whom he sells the patent, can make,
use and sell the invention, and license
others to do so, without let or hin-
drance from the employer.
"As to persons employed to invent:
If a person is employed by another to
make inventions to be used in the em-
ployer's business, and is paid salary or
wages on the understanding that his
services are to be those of an inventor
in improving the machines, tools or pro-
cesses which relate to the employer's
business, then the inventions which the
employe makes relating to that busi-
ness and the patents granted therefor
are the exclusive property of the em-
ployer. In such cases the court says
that the employe, in making and per-
fecting inventions, is merely doing what
he was hired to do.
"Should the employe leave that em-
ploy, he cannot use, or make, or sell
the invention, or convey any rights to
others under it, except with the con-
sent of the employer."

The 240-stamp mill was run 154 days by
water power and 158 days by steam
power. The 300-stamp mill started May
6th, 1899, and was hung up from Jan. 3d
to March 21st, 1900.
Wages paid were as follows, the com-
pany providing in addition board and
lodging for all workmen except Indian
laborers : Machine drillers, $2.50 per day
in summer, $3 in winter ; machine helpers,
$2.25 ; mine laborers (white), $2 ; amalga-
mators, $90 a month ; feeders, $70 ; van-
nermen, $65 to $100 ; machinists and help-
ers, $2 to $6 per day; blacksmiths, $4 ; drill
sharpeners, $3.50 ; blacksmiths' helpers,
$2. Indian laborers receive $2 per day
without board.
The report of Supt. J. P. Corbus says :
"Exploration and development work for
the year includes 1807 feet drives, 465 feet
crosscuts, 1103 feet raises, 60 feet pump
station and 20 feet sump, a total of 3455
feet. Of this 50 feet was on the adit level,
470 feet on the 110-foot, 1297 feet on the
220-foot, 1104 feet on the 330-foot, and 597
feet on the 440-foot. On the adit level a
50-foot crosscut was run, connecting No. 2
main shaft at surface with the adit tunnel,
which greatly facilitates the transporta-
tion of ore from the shaft to the 240-stamp
mill.
. " On the 110-foot level No. 1 east drift
was extended 137 feet to our end line, con-
necting with workings of 700-foot claim.
An intermediate drift, 75 feet in length,
was run above this No. 1 east drift, and
195 feet of raises were put in to connect
with intermediate drift and also with No.
1 and No. 4 pits. Samples taken gave as-
say returns of $2.08 per ton. On the 220-
foot level No. 6 east drift was run 177 feet,
connecting with old No. 5 east, which has
a connection with No. 1 shaft of 700-foot
claim ; 525 feet of intermediate drifts were
run on this level, and 515 feet of upraises
for chutes. Assay returns from samples
taken along No. 6 east drift show that ore
from this section of the mine carries very
good values. A pump station, 12x15x40
feet, was cut, and a sump 10x10x20 feet
deep was sunk for the Riedler pumping
engine. On the 330-foot level the main
crosscut was driven ahead 415 feet, and
the face is now into the slate footwall a dis-
tance of 25 feet. This crosscut measures
442 feet from No. 2 main shaft to face, or
492 feet from end to end. On this level we
find much the same condition of affairs as
exists on the 440-foot level ; the vein is
about the same width as on the upper
levels, but averages less, owing to the vein
being mixed with slate and granite. There
is a width of about 190 feet on this level
that will pay to stope. The 330-foot level
is connected to the 220-foot level by a raise
along the footwall at the end of the main
crosscut, measuring 125 feet. There is
also an intermediate drift on this level
measuring 95 feet in length, 120 feet of up-
raises for chutes and .'149 foot of drives.
On tho 440-foot level development work
during the year was 118 foet along No. 1
east and west drift, 301 feet along No. 5
east and west, 105 foot of upraises for ore
chutes, and 73 foot of a 7x9-foot raise to
connect with 330-foot level. The ore de-
veloped by this work proves to be of a pay-
able grado. There was no sinking done
during the year. It is proposed to resume
sinking at No. 2 main shaft early during
the coming year.
"Exclusive of pits, tho approximate total
development in mine May 15, 1900, is as
follows: Drives, 7802 feet; crosscuts. .1200
feet; raises, 2629 feet; shafts, 778 feet;
total, 14,469 feet. The location of the
above is as follows: Adit level, 910 feet;
110-foot level, 4394 foot; 220-foot level, 0110
feet; 330-foot level, 1217 feet; 440-foot level,
1060 feet; No. 1 shaft, 272 feet; No. 2 shaft,
506 feet; total, 14,469 feet.
"The ore mined and sent to mill May
16, 1899, to May 15, 1900, was 557,960 tons.
The estimate of ore in sight and availablo
for mill May 15, 1900, is as follows: Adit
and 110-foot levels, 1,514,408 tons; 220-foot
level, 2,115,708 tons; 330-foot level, 226,849
tons; 440-foot level, 274,675 tons; total, 4,-
131,640 tons. On the 330 and 440 levels
account is taken only of ore developed to
the ends of drifts east and west. With
each additional foot of drift run on these
levels the ore reserves increase very
largely.
" On May 12 a slide containing over
100,000 tons of quartz and slate came into
No. 3 and No. 4 pits from footwall. This
will not interfere with mining operations,
and carries sufficient value to warrant
milling entire quantity.
"The total run for the year at the 240-
stamp mill was 312 days, 9 hours, 41 min-
utes, during which time 225, 722 tons of ore
were crushed, the duty per stamp per
twenty-four hours being 3.01 tons, as
against a run of 353 days, 2 hours, 50 min-
utes, and a duty of 2.95 tons per stamp for
previous year. The large loss of running
time at this mill was due to the following
causes : Holidays, 2 days ; shortage of bat-
tery water, 2 days ; shortage of rock due
to scarcity of laborers at mine, 42} days ;
broken water wheel shafts, 1J days ; clean-
ups, 2\ days ; various other causes, such as
repairs to batteries, changing from water
power to steam power and vice versa,
splicing ropes, etc., 2J days; total loss of
time for the year, 52| days. On May
15th, after a run of over 15 years, this
mill was closed down for extensive repairs,
it being the intention to renew the ore
bins, ore-bin foundations, battery founda-
tion and battery framework throughout.
No work will be done on the mill building,
as that still remains in good condition.
Timber for reconstruction work is Wash-
ington fir, and was purchased and framed
at Seattle, Wash. To complete first sec-
tion (forty stamps) will require until about
July 15. Half of the mill should be fin-
ished and dropping on ore by August 15,
and the full mill of 240 stamps should be
running not later than October 1, 1900.
" An excellent record was made at the
300-stamp mill during last year, both as
to running time and crushing capacity.
The running time was 270 days, 5 hours,
45 minutes; the amount of ore crushed
was 332,238 tons, or a duty of 4.07 tons
per stamp per 24 hours. Last winter was
an exceptionally short and mild one, con-
sequently the water season for this mill
was much longer than usual. Under or-
dinary conditions, I believe it will not be
possible to run this mill by water power
for more than 7J months per year, or say
the mill has a capacity of 285,000 tons per
year.
"The total amount of ore crushed at
both mills last year was 557,960 tons. The
yield of sulphurets amounted to 9825 tons,
all of which was shipped by barges and
steamers to Tacoma for treatment by Ta-
coma Smelting Co. The total cost of
shipping and treating sulphurets last year
was $79,385, or $8.10 per ton. This high
rate was due principally to the fact that
parties who contracted to carry our con-
centrates in bulk from the mill to Tacoma
failed to place at our disposal a sufficient
number of barges to properly care for our
product; consequently, we were forced at
times to ship by other means at an in-
creased rate of freight, besides having to
stand the additional cost of sacking the
sulphurets so shipped. Given proper
shipping facilities, our sulphurets should
be shipped in bulk and treated at a cost
not to exceed $7 per ton."

as 38,491 tons, yielding $51,660; 661 tons
sulphurets are valued at $19,19" ; bullion
product for month $76,006, ore averaging
$1.97 per ton ; expenses for month, 931,000°

The London Statist says India absorbed
50,000,000 ounces of silver in the year end-
ing Sept. 1, and predicts that that coun-
try will want nearly one-quarter of the
world's production.
Chinese currency and currency regula-
tions present some most peculiar features
and the currency customs of the province
of Kwang Tung, the province of which we
know most, as are remarkable as any.
Roughly speaking, the currency of the
Kwang Tung province consist of what may
be called "chopped dollars," or broken
silver, and Canton subsidiary coins of 10
and 20 cents. The dollars in circulation
are principally Mexican, but the Japanese
yen (silver dollar), the Hongkong dollar
and the Kwang Tung dollar are also cur-
rent. All these dollars are supposed to be
of the same weight and fineness — that is,
of 416 grains .600 fine. The variation, if
any, is very slight. All Chinese merchants
and bankers stamp with an iron instru-
ment every dollar that passes through
their hands, and in the course of time
these coins become defaced and broken,
when they are denominated "chopped
dollars," or "broken silver." Chopped
dollars, Kwang Tung dollars and subsidi-
ary coins are not current in the British
colony of Hongkong. "Clean dollars, " or
dollars not chopped, are usually at a pre-
mium of about 2%.
The local currency is in no way guaran-
teed by the Chinese Government. It is
taken on its own merits only, which ne-
cessitates examination by merchants and
bankers of every dollar that passes
through their hands, and the "chop " is
to enable them to recognize any dollar
they may have paid out. Hongkong bank
notes pass freely, being preferred to silver,
and are therefore at a premium. The
bulk of the merchandise shipped by the
foreign merchants is paid for by checks
on Hongkong, which can generally be
sold to the native banks at a pre-
mium varying one-fourth of 1% and some-
times as high as 14%. The Chinese mer-
chants, in effecting exchanges between
themselves, use the taels. This is not a
coin, but merely a weight of silver, and is
considered the local currency. Seventy-
two taels are equal to $100. Among the
poorer classes and in the country districts
the copper "cash " is used, of which 1000
are about equal to a dollar. The Mexican
dollar and the Japanese silver yen are
legal tender when not chopped.
From the foregoing it will be observed
that the local currency is debased. It is
not legal tender in Hongkong — that is to
say, the chopped dollars. Kwang Tung
dollars and subsidiary coins are accepted
by the Government and by the banks and
merchants, but shopkeepers will accept
such money only in small sums. Nearly
all foreigners residing in Canton — particu-
larly the merchants — keep the bulk of
their money in the Hongkong bank, and
draw against their deposit by check when
required.

Notices of Recent Patents.
. Among the patents recently obtained
through Dewey, Strong & Co.'s Scien-
tific Press TJ. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Locomotive Headlight. — No. 659,-
795. Oct. 16, 1900. McDonald Elliot of
Santa Rosa, Cal. The object of this in-
vention is to provide an apparatus for the
production of acetylene gas under such
conditions that when the generator is sub-
jected to violent shocks and oscillations,
the water contained therein is prevented
from splashing about under the violent
movements. The gas is manufactured in
only sufficient quantities to supply the
single light which is used for locomotive
headlights and for which this apparatus
is especially designed. Means are provided
for staying the How of gas under the con-
ditions of violent movements caused by
the high speed of a locomotive, and means
for automatically regulating the supply of
water to the carbide and disposing of any
water of condensation so as to keep it
away from the carbide when not wanted.
The generator consists of an outer casing
having sufficient vertical height and made
comparatively narrow in diameter. This
is provided with an internal water seal and
a rising and falling gasometer moving in
the channel which forms the seal. A
carbide chamber and ash chamber are re-
movably located in the lower part of the
gasometer, the upper edge of the carbide
chamber being roughened so as to provide
small passages for the gas between the
roughened edges without allowing a suf-
ficient space for irregular waves or move-
ments of the gas which might be caused
by sudden shocks of the apparatus. The
valve by which water is admitted into the
carbide containing chamber or basket is
operated by a lever or fulcrum that when
the gasometer sinks by reduction in
quantity of gas within it, it will strike
the lever and open the water supply, and
when it rises it relieves the lever and the
valve is closed by a spring or other suit-
able means.
Gopher Trap.— No. 659,932. Oct. 16,
1900. Z. A. Macabee, Los Gatos, Cal. The
object of this invention is to provide an
improved trap for catching gophers and
similar burrowing animals. It consists
essentially of a spring frame having
transverse pointed interlocking arms at
one end, loops through which these arms
pass, and which when the trap is set by
depressing the upper portion will sepa-
rate the interlocking arms. A plate is ful-
crumed upon the framework and a trigger
engaging the plate holds the arms sepa-
rated when the trap is set. The trap is
then pushed into the hole so that the plate
is in such position that when the gopher
pushes out the dirt, as is his custom, it
contacts with the plate and disengages
the latch, thus allowing the arms which
are operated by a stout spring to close to-
gether and impale the animal.
Powder Mixing and Incorporating
Mill.— No. 660,373. Oct. 23, 1900. F. A.
Halsey, San Rafael, Cal. The object of
this invention is to provide certain im-
provements in mills which are designed to
mix the ingredients of explosive powders
and the like. It consists of an annularly
channeled bed with runners and plows,
and mechanism by which they are caused
to travel around said bed. Means are em-
ployed for holding the runner out of
direct contact with the bed, and disinte-
graters are fitted to travel with the run-
ner, these disintegrators consisting of a
series of disks or hubs mounted side by
side upon a shaft and having radial arms,
the ends of which are disposed in spiral
lines from side to side so that as they
move over the powder on the bed, they
will act to break and disintegrate it into
small particles. A lever arm is fixed to
the shaft upon which these disintegrating
arms or disks are carried so that the
weight may be adjusted to provide a vary-
ing pressure upon these arms as they pass
over the material on the bed. The main
object of this improved mill is to produce
100% more grain of such dense powders as
are granulated in the mill immediately
after incorporation, and reducing labor and
time 50%, and avoiding the ever-present
danger of rubbing the incorporated ma-
terial through sieves. After the composi-
tion has been properly incorporated the
runners of the mill are raised sufficient to
take the pressure off the cake and the
circular cutters (which have been thrown
over the plow during incorporation) are
now dropped down ; with a few revolu-
tions the runners will have rubbed up the
coarse cake ; they may now be raised en-
tirely while the mill is in motion by grasp-
ing the hand wheel on top. The plows
and cutters continue in action, causing
the rapid formation, with proper moist-
ure, of round grains, this action to be con-
tinued until granulation is complete.
Dry Concentration by the Crown Process.
The Salt Lake City, Utah, Herald says :
F. A. Flindt and S. W. Mosby have re-
turned to Salt Lake City from San Fran-
cisco, thoroughly convinced that at last a
practically perfect method of treating ores
by dry concentration had been devised,
and will call for their lease on the second-
class ores of the May Day, equip the prop-
erty with a plant and get down to business
by Jan. 1st.
Before leaving for the coast to investi-
I gate the merits of the Crown Gold Mining
| Co.'s new dry process they shipped a ton
1 of second-class ore with the purpose of see-
ing it tested, and on his return Mr. Flindt
told the Herald that he had "witnessed
the most wonderful performance he ever
saw in the way of concentrating ore."
The ore tested carried 8% lead in its crude
form and the concentrates assayed 56%
and the tailings contained only .98 of
1%, the closest saving Mr. Flindt ever
saw.
Of the practicability of the process Mr.
Flindt says there is no doubt, but the
company guarantees nothing before dem-
onstrations are made, and will not then
sell the machines. When it is shown that
the ores submitted can be successfully
treated they contract to put in plants of
adequate capacity to meet the require-
ments of each case, bear the cost them-
selves and charge a royalty for their use.
If other arrangements are not made with-
in the next few days, Messrs. Flindt and
Mosby will contract with the California
company owning the new process to in-
stall it at the May Day.
The Salt Lake Tribune quotes F. Enzen-
sperger, who made himself conversant
with the new process for the concentra-
tion of low-grade, ores to be introduced at
the May Day of Eureka by Messrs. Flindt
and Mosby, as saying that it "promises to
revolutionize the handling of that class of
mineral, and that repeated tests have
demonstrated that it is all which has been
claimed for it. In the elimination of the
gangue and the concentration of the met-
als, Mr. Enzensperger says a stream of air
is applied to the ores as they pass over a
fine silken belt and after they have passed
through various meshes until they are
practically reduced to a powder. With
the aid of air the gangue is eliminated
during the movement of the ore and the
metals are deposited in the receptacle that
awaits them. The new method is known
as the 'Crown process.' It was developed
by F. W. Wood, a California metallurgist,
and is being exploited by Loring B. Doe of
San Francisco, from whom Mr. Enzen-
sperger is in receipt of a letter calling at-,
tention to the process. The latter as well
as the inventor is expected in Salt Lake
in a short time, and it is not unlikely that
a branch manufactory will be installed
at this point." *

SPADONE'S CONCENTRATOR BELTS.
PATENTED.
This illustration shows the edge flanging out-
wardly as it passes over the pulley. This re-
lieves the strain from the top and bottom of the
edge by directing the strain automatically to
the inside face surface of the edges. Hereto-
fore all belts have been so constructed that
when they pass over the pulleys or rolls, a di-
rect strain comes upon the top or at the base of
of the edges, causing the edges to break away
from the body of the belts in a very short time.
We avoid this Mechanical Defect by our Spadone
Curved Edge. Belts made to fit any machine—
4, 5 and 6 feet wide. Prices and samples on ap-
plication.
AMALGAM PLATE CLEANERS.
Our Amalgam Plate Cleaners are made of Pure Rubber in moulds, thus insuring a plate cleaner
which will not scratch the plates and a perfect edge which will clean the Amalgam plates evenly.
They are made 6 inches long, 3 inches wide and % inch thick, making a convenient size to handle.
Price by mall to any address, each 75 cents. Correspondence solicited.

Smelting Zinc Ores.
Colorado is considerably interested in the smelting
of zinc ore, or the profitable disposition of low-grade
ores carrying zinc. It was thought that they might
be shipped foreign, but ores carrying less than 45%
zinc do not pay to export. Nor are the foreign
smelters any better prepared to treat zincy ores
than the local plants. Cheap labor, cheap coal and
other supplies give foreign smelters some advantage,
but there is no metallurgical superiority. Zinc ore
has been sent from Leadville to Swansea for $9 per
ton, and about as low a rate has been secured to
Antwerp, but neither Welsh nor Belgian smelters
have shown i any superiority in securing returns.
They have placed 43% zinc as the limit, and for ore
carrying that they pay $4 per ton, deducting 60
cents per unit for each unit under 43, and paying 60
cents for each unit above that figure; but Leadville
miners say that at those figures there is no margin
over the cost of mining and hauling.
The quantities of ore carrying 30% and less in zinc
have been virtually valueless, but it is thought that
a suitable system of concentration, and a change in
the method of lining zinc furnaces, may result in a
more effective and economical system of zinc distilla-
tion by excluding the lead and iron. The presence of
over 1% of iron or 3% of lead militates against suc-
cessful zinc extraction, and if a method of lining
zinc furnaces could be devised that would resist cor-
rosion, the action of the iron oxides which ordinarily
destroys the fire clay of which the retorts are made
could be successfully resisted, the idea being to apply
such sintering material to the lining as to produce a
solidly cohering substance impervious to iron oxide
or other corroding ingredient, and capable of sus-
taining the heat to which it would be exposed.
The prominence of what is known as " the low-
grade proposition " is one of the most noticeable
features in the gold mining of to-day. Time was
when the " ounce-a-day " placer diggings, or the
superficial quartz of high grade, alone found favor.
Those days have passed ; high-grade mines still at-
tract investment and due attention, but the "low-
grade proposition," the big deposit of lean ore, in
quantity sufficient to make permanent calculations
upon, the large amount that gives promise of small
hut steady dividends, is that which now attracts the
greatest al trillion.
Men, " Busy " and Otherwise.
. At times, as a matter of general benefit, it has
been suggested herein that an account of anything of
effective value produced in the mining and metal-
lurgical world likely to be of common benefit might,
with propriety, well appear in this paper for the
common good, on the principle that ' ' everybody is
wiser than anybody," and that " my light is none the
less for having lighted that of my neighbor." It is
manifest to many of those whose opinion is worth
having that much of practical value may be told by
the men who do things.
It is customary now with technical journals to en-
courage such interchange of information. The lead-
ing London journal of the kind keeps the following
constantly at the head of its announcements : ' ' Many
of our readers have had experiences in mining and
milling, some record of which would be of great in-
terest and value to others. Many have made experi-
ments in different directions, and others have met and
overcome difficulties in practice, some of which would
help others in like cases and give them practical aid.
Such readers would do great service to us and to
their fellow workers by sending us from time to time
some notes of their experience. They would be wel-
come, however brief, and, we are sure, would be read
and appreciated by many."
Of course, during the forty years of its existence,
this paper has probably published more original mat-
ter of that kind, namely, how things are done, by the
men who do them, than any other journal in existence ;
but, yet, there are many among its readers who make
no record of their successful experiments and experi-
ences in mining and metallurgical practice, and who
when they read such suggestions as these, while they
silently acquiesce, and, maybe, get so far as to think,
"Well, I shall, some time, send the Mining and Sci-
entific Press some notes of what I think was a suc-
cess in this case ; " yet, when the regular day's work
is done, other duties may come up, or one may feel
" too tired " to put his good resolve into execution.
The most common excuse or reason that a man gives
himself and others for not doing these things and
others is, that he is " too busy." No doubt, many of
us wish that the days were sometimes more than
twenty-four hours long, and, yet, everyone has all the
time that there is, and a little exact regulation of
hours and duties helps greatly in giving one the
necessary time to devote to other things which some-
times embrace the best things of life — things that can
not be paid for in current coin, but yet are none the
less valuable, not only to the giver, but to the. re-
cipients.
This matter of being " too busy " is more of a habit
than a fact. As we write we have in mind a leading
Colorado miner, who finds time to send many matters
of great practical value to this journal. One might
think he was a very busy man ; he is superintendent
of five several mines ; makes long journeys over this
west half of America as an examiner of mining prop-
erties ; gives expert testimony in mining litigation ;
bestows some practical attention on mining problems
that come up in his daily life ; and, as he was recently
elected to the Colorado Legislature, will doubtless be
heard from there in aid of the miner this winter.
Yet this man is not " too busy " to write articles on
mining and metallurgy for this paper — articles whose
merits are so manifest that they are copied elsewhere
immediately upon their appearance. There also
occurs to our mind an almost precisely similar case
in California, except that the Californian who is not
' ' too busy " to send results is only superintendent of
two mines instead of five. These two mining men are
instanced as illustrating that men may be fairly occu-
pied in large enterprises and yet not be "too busy"
to accord a little of their information to their fellow
miners and metallurgists. As a matter of fact, none
but busy men are asked to do these things, as the
man competent to give pointers of value is usually in
demand to work for himself or others, and the fact
that he is busy shows that he amounts to something.
Some may have also in mind gentlemen whose ability
is more than commensurate with their energy, who
spend their time going round telling others what
busy men they are, and, doubtless having said it so
much, they believe it themselves. The latter class
are not cited for criticism, so much as the two former
are instanced as indicative of what men may do,
though really busy.
The Leasing System.
In Colorado and other States the leasing system
has of late years aided much in mine development,
though, so far as the lessees are concerned, their
share has not always been commensurate with the
effort and expense. The system of leasing deserves
commendation ; where from inability or other reasons
the owner of the ground is unable or unwilling to
work it, the lessee offers usually good opportunity to
demonstrate its value. Many leases are expiring in
Colorado and elsewhere, and business justice to the
lessees, as well as a wise system of mutual co-opera-
tion, which results eventually in mutual profit, would
suggest that a fair division of profit be accorded the
lessee. Often he takes all the risk of loss ; does most
or all of the work, and, where successful, the owner
of the claim or the mining company as often gets the
biggest share ; but in case of failure the loss falls
mostly upon him. Few fortunes are made by lessees,
though in the majority of cases moderate money has
been realized by intelligent effort and diligent prose-
cution of work. The most of such money has been
made by the claim owners or mining companies, many
of the latter having reverted to the system of leasing
their properties after having tried themselves to
make a success.
A high rate of royalties works against the lessee ;
even with a fairly profitable lease, if nearly all his
profits have to go to the property owner in royalties
there is little inducement for continuance. He may
be able to stand off the railroads and hold things
even with the smelters, but with a high royalty there
is seldom sufficient or favorable opportunity for the
systematic and extended working that would result
in common profit to all. Another thing that would
help the lessee would be a longer period for which
leases were granted. There is rarely objection on
the part of those who lease their properties, so long
as they are unproductive, to have the lessees dili-
gently develop them, objection to continuance some-
times arising when they have demonstrated their
value. A good way to do in connection with such
general suggestion of extension of the time for which
leases are ordinarily made would be to date those
leases from the time of the first shipment of ore. It
is bad to attempt to make too hard a bargain with
anybody; it is not business to trade upon anyone's
necessities in causing him to do that which by force
of circumstances he may have had to do.
The relation of this whole system of leasing to the
development of the mineral wealth of any region is
sufficiently manifest to justify notice. Usually a
property that is being worked under lease is econom-
ically managed. Of course, it is not advised — nor
would any intelligent mine owner consider it good
business — to turn his property over to leasers, but in
many a case where opened properties have been
abandoned by the owner, or by the company, because
of the lack of money or intelligent management, the
lessee has made money for himself and the claim
owner where previously everything lay idle, and in
making that money — as also as in all cases where
mining is going on — he makes times lively for the sur-
rounding vicinity to the extent of production, for
every miner employed gives employment to ten
others who are not miners, but who share in the cre-
ated wealth. And lessees are usually not content
with even that, but when they have made a little
money they generally use it in opening up other
abandoned properties, or in developing new terri-
tory, and in this case they constitute just the kind of
capital needed in the mining business — intelligent
mining with the gambling element left out of it; min-
ing by men who know what they are doing and have
nerve enough to put their money into mining opera-
tions that take nothing from any one but benefit
in common, with all the local advantages that such
condition confers.
It is not uncommon to look to "Eastern capital"
and " foreign investors " for money necessary for de-
velopment. Both sources of mining capital are com-
mendable and welcome, but it sometimes occurs that
in looking too far afield for the necessary elements of
developing, an important factor in the problem may
be overlooked, that is, the lessee. This is not a plea
nor an argument for the lessee, who is usually able
to take care of himself, and is merely intended to in-
dicate in what direction mutual aid and profit may
often lie. The subject is an important one.

Concentrates.
The bottom of tho Banner mine shaft, Butte county,
Cal., is 500 foet below sea level.
Next to mismanagement, the most fruitful cause of
failure in mine development is insufficient capital.
THE caving system has been employed in iron ore
mines for many years, and is now applied to the mining
of copper ore in the Utah Consolidated, Utah.
At an elevation where the aneroid barometer registers
21 inches, the theoretical height to which a pump will
suck is 24 feet; the actual suction would not be over 17
feet.
A 5 H. P. engine ought to run a dynamo to supply
forty lights of sixteen candle power each. A gas engine
would do if it had a balance wheel heavy enough to run
uniformly.
The Rio Tinto is Spain's biggest copper mine, and
from about 1,500,000 tons pyrites annually extracted
about 20,000 tons copper are produced. There is an an-
nual profit of about $800,000.
It is not uncommon to work over the same ore with
cyanide two and even three times. Near Wickenburg,
Ariz., tailings from the old Vulture mine were recently
treated for the third time at a profit.
IF two men on opposite sides of the earth looked
along two parallel lines when the sun was midway be-
tween the lines, both would see the sun in the same
place, but it would be rising to the one and setting to the
other.
A piece OP TOOL steel should in all cases be left in
the water at least as long as it was in the fire. If it
takes twenty minutes to heat up a piece it should be left
in the water twenty minutes to cool, and longer if nec-
essary.
The Gwin mine, Calaveras county, has probably as
large a pay shoot as any in California — over 1400 feet.
An item like this will bring reports for the next ninety
days of ore shoots elsewhere from 1500 to 15,000 feet in
extent.
A new hydrocarbon — a solid — is made by passing
pure dry acetylene gas through a tube containing finely
powdered copper. The cuprene thus formed is almost
insoluble ; neither nitric nor sulphuric acid has much
appreciable effect upon it.
Crookes says that his experiments indicate that iron
at high temperature and under great pressure will act
as a solvent for carbon, and allow it to crystallize out in
the form of the diamond — conditions existent at great
depths below the surface of the earth.
The average piston speed in engines with cylinders 4
to 7 inches diameter is about 400 feet per minute; above
7 inches, about 550 feet. The number of revolutions is
found by dividing the required piston speed in feet per
minute by twice the length of the stroke in feet.
The use of coal which contains sulphur will cause
deposition of sulphuric acid upon the walls and tubes of
the boiler, necessitating frequent cleaning. The more
moisture the greater the corrosive action of the acid.
Mixing lime with the coal prevents such acid formation.
In tests made by engines, one pound anthracite coal
evaporated 9.7 pounds water from and at 212° F.; one
pound bituminous coal evaporated 10.14 pounds water;
one pound fuel oil, 36° gravity, evaporated 16.48 pounds.
A cord of well-dried white oak weighs 3850 pounds, is
considered equal to 1600 pounds bituminous coal.
A plying machine is considered feasible, and one
capable of sustained flight will undoubtedly be produced.
Probably the greatest (and, perhaps, unsuperable) dif-
ficulty will, however, be met with in the matter of alight-
ing. Safely reaching the ground after prolonged flight
will he the hardest part of the problem to solve.
For the Diesel motor or oil engine is claimed a theo-
retical heat efficiency of 50% for the single cylinder en-
gine, and 70% for the compound type. The heat
efficiency of a good gas, gasoline or oil engine is from
15% to 30%. The Diesel motor was described and illus-
trated in the issue of Nov. 12, 1898.
The volume of compressed air delivered at sixty
pounds pressure at an elevation of 10,000 feet is 72.7% of
the volume delivered at the same pressure hy the same
compressor at sea level. A compressor which, at sea
level, would supply power for ten rock drills, would, at
an altitude of 10,000 feet, furnish air for only seven
drills.
The principle of the pyrometer is based upon the ex-
pansion and contraction of two metals, an iron tube be-
ing inclosed in a copper tube, or vice versa, both being
connected at their lower ends; the difference in the ex-
pansion of these tubes under heat is transferred by a
movement to a pointer, which indicates the temperature
on a dial.
Wood, like gaseous coal, distills off volatile or tarry
matter, often sticky, and brown in color, and combusti-
ble, if sufficiently high temperature is reached. These
do not constitute a true "smoke." In the engineering
use of the word "smoke " it is to be understood that
where the carbon particle does not burn to gas while hot
enough to unite with oxygen, it cools to black carbon,
lampblack, or soot, and a current of gas carrying such
solid black particles in it is called "smoke."
It is bad practice to overheat a steel tool in hardening
and then allow it to cool slowly in the air until it has
taken a certain color before plunging into water, since
the coarse grain of the high heat will be loft in the tool
and it will not do good work. Self-hardening steel can,
of course, be cooled in air without detriment, but it is
not well to heat it too hot.
Theoretically, a cord of dry oak wood is figured to
have a value of 40,425,000 British thermal units; one
ton— 2000 pounds— good coal, 29,400,000 units; one bar-
rel—42 gallons— crude oil, 6,150,000 units. On this basis,
4.78 barrels oil would equal one ton of coal, and 6.58 bar-
rels oil equal one cord dry oak wood. In practice the
relative proportions and values differ from these figures.
Ore impregnated with arsenioue or sulphuric acid
could probably be economically treated by the cyanide
process, if, after light roasting, application be made of
chlorate of lime. Jos. Smith at Pine Grove, Nevada,
claims to have so successfully treated such acid ores, se-
curing an extraction of 90%, with a consumption of
potassium cyanide of one and one-fourth pounds per ton
of ore.
Where a man takes a mining property under a bond
and lease, with nothing expressed as to what shall be
done with the machinery for exploitation, such machin-
ery belongs to the lessee, and the latter has a right to
remove it at any time during the life of the lease ; and if
the lease be forfeited for any reason, he can remove the
machinery within a reasonable time after such for-
feiture.
In connecting a safety valve to a steam boiler, if pro-
vided with a flange joint, it should be bolted to the top
of the dome ; if it is threaded for a pipe, the connection
with the top of the dome or its equivalent should be
as direct and as short as possible, and of the same size as
the opening in the valve. No valve or other fittings,
screwed or flanged joints should he placed between the
safety valve and the dome.
To clean rusted tools and instruments of steel, if the
rust is heavy, stand the tools in coal oil for a few hours,
but if only slightly rusted this is not necessary. Next
dip the articles in liquor potassa for a few moments and
then put them into a strong solution of potassium cya-
nide. Remove ; clean with a paste of the cyanide, castile
soap, chalk and water ; rinse, and place in a saturated
solution of chloride of tin and leave over night. In this
manner every particle of rust is removed and the articles
will come out clear and of a silvery whiteness.
The "banket" of the Witwatersrand district, South
Africa, is a siliceous mass, consisting of quartz
pebbles embedded in a matrix composed of sand, pyrite
and other minerals, all cemented by secondary silica.
The large quartz pebbles have all the characteristics of
vein quartz, but show under the microscope undulous
extinctions and other evidences of dynamic action to
which they have been subjected. They are frequently
cracked, and then sometimes show veinlets along the
fractures. The quartz pebbles often carry pyrite and
other sulphurets, as zinc blende and galena.
The lowest temperature registered in the open air by
any thermometer on earth is 90° below zero, F. The
lowest laboratory temperature registered is 434° F. below
zero. This temperature was obtained by Prof. Dewar
hy evaporating frozen hydrogen in a vacuum. "Abso-
lute zero" is 459° F. below zero. "Absolute zero"
means that degree of temperature at which heat ceases
to exist. It is accurately determined by the fact that all
gases expand and contract alike at the freezing point, at
the rate of 7jB part of their volumo for one degree. As
this contraction is due to loss of heat, it is manifest that
when a gas has contracted 459 parts it can contract no
further — its heat is all gone and its temperature then is
"absolute zero."
This from Wallace, Idaho, is one of the hard ones.
It was received a month ago, and has been the subject of
much unavailing research. ' ' In placing a magnet between
the ore bin and the crusher, to catch hammers, steel,
etc., what is the arrangement? Must there be a current
passing through the magnet aE the time, or can a piece
of steel or iron be charged from time to time and be ef-
fective ? Of what are magnets for this purpose usually
made, and how are they placed ? . Will a hammer remain
on the flat surface of the magnet or will it have to drop
over on the end to be arrested ? " Never heard of just
such an arrangement. T. A. Edison had some device
for using magnets to separate the iron in auriferous
sands, fully described and illustrated at great length in
the issue of April 30th, 1898.
Probably "spontaneous ignition" is a more exact
term than "spontaneous combustion." That action is
caused by the absorption of oxygen by any combustible
matter so fast that the resultant combination raises the
temperature to a point at which it will burst into a flame.
The condition that favors such action is the presence of
a body readily oxidizable, distributed in a finely divided
state over some material whereby considerable surface is
exposed to action by the oxygen. Oily rags and greasy
waste fill this condition, and both are specially liable to
the accident. The more oxidizable the oil the more im-
minent the danger. Vegetable oils are particularly
liable to the accident. In coal dust in bunkers, because
of the oxidation of the sulphur in it, also may occur
spontaneous ignition.
Magnesite is used largely in the steel industry,
where bricks made from calcined magnesite are used for
lining furnaces and converters. Magnesite bricks of
high grade are composed of 94% carbonate of magnesia ;
they are refractory and last longer than others. Cement
manufacturers also line their kilns with those bricks.
During the twelve years ending with 1898 California pro-
duced 6879 tons magnesite, worth $60,766. In European
open-hearth steel works about forty pounds magnesite
are used for each ton of steel produced. Greece is tho
greatest producer of magnesite, annually shipping about
20,000 tons to the United States, where it is landed at a
total cost in Atlantic ports of about $4.50 per ton. Mag-
nesite bricks are made therefrom by Fayette Manufac-
turing Co., Layton, Pa., and Harbison & Walker, Pitts-
burg, Pa. The imported manufactured magnesite bricks
are worth about $175 per thousand at New York or
Philadelphia.
Uranium belongs to the chromium group of elements,
which includes also molybdenum and tungsten. It is a
white metal, resembling iron or nickel, malleable, nearly
as hard as steel, and is capable of a high polish, a specific
gravity of 18.7. It is not a very abundant element; and
not having superior metallic qualities, it has not found its
way into the arts as a competitor to the cheaper metals.
It is not found as a natural metal. The chief ore is
pitchblende, which consists mostly of an impure uranic
oxide. There are various methods of obtaining uranium
from this ore. Uranic oxide yields, by the action of
acids, uranyl salts, which are highly sensitive to light
and are used for photographic purposes. The most im-
portant compound of uranium, from a practical point of
view, is uranium yellow, a sodium of di-uranate, which is
extensively used in painting and enameling glass and
porcelain and for preparing uranium glass. Uranium
salts are very readily separated from iron compounds
and the process is not costly. The world's production
does not mount high up into the thousands. Colorado
is credited with seventeen tons of ore in 1898, valued at
$530 per ton. The oxide fluctuates $2.25 and $4 per
pound, while pure uranium is worth about $190 per keg,
about two and one-half pounds.
By the Russian mining laws, which greatly need
changing, all the gold extracted must be delivered to
the government gold laboratory of the district, where it
is smelted and weighed, and an "assignat " delivered to
the owner for its value, less the tax (from 3% to 10%
upon ordinary mines, and 15% upon the mines which are
the Czar's private property), a charge for laboratory
fees, the cost of transmission to St. Petersburg, and a
margin in case the local laboratory should have made an
error of weight or assay in the vender's favor. The rate
of purchase is fixed by the government. Six months or
so later the head laboratory pays over the balance, but
in the meantime the vender can cash his "assignat."
Under these rules the private purchase or even posses-
sion of gold is a penal offense, exactly as in case of dia-
monds at the Kimberly, S. A., diamondVflelds. But as
illicit diamond buying exists there, so illicit gold buying
flourishes at Irkutsk, and the Chinese merchants are
the offenders. They hang a few furs outside of a shop,
or put a few chests of tea in the window, but this is
merely a blind, for they make big profits by buying
gold dust in quantities from a pinch to a bucketful, and
smuggling it across the frontier into China. The Irk-
utsk gold laboratory was founded in 1870, and since then
1,173,456 pounds avoirdupois of gold, worth probably
$300,000,000, has been sent thence to Europe.
In treating' slimes in Australia, the slimes are trucked
to the works, and there the required quantity of quick-
lime to neutralize the acid contained in them is added as
the trucks are emptied into a hopper discharging into a
disintegrator. The lime required per ton of dry slime
varies from twenty to sixty pounds. After passing
through the disintegrator, the powdered mass is raised
by a bucket elevator to a top hopper, which discharges
into side tip trucks running over the tops of the vats.
Over each vat is a 6-inch centrifugal pump, the suction
pipe of which descends at an angle to within 2 feet of the
bottom of the vat, while the discharge pipe is continued
down to the floor of the vat, where it is terminated by a
right angle bend on a swivel point, so that the flow can
be directed across to any part of the vat. The vat, be-
ing filled with solution of cyanide, the centrifugal pump
is started, and in a few minutes the whole mass is in vio-
lent agitation. Into this agitated liquor the powdered
slime is dropped, truck by truck, until the whole charge,
amounting to ten tons, is delivered, the agitation being
maintained the whole time. A few minutes after the
last truck is dropped in, the pump is stopped and the
whole mass allowed to settle; this occupies twenty min-
utes, the solution being left absolutely clear on top. A
pipe, mounted with swivel joint, and connected with the
pipe service leading to the zinc extractor boxes, is then
gradually lowered until the whole of the supernatant so-
lution is drawn off. The vat is then filled with the weak
solution, and the pump is once more set in motion; in a
few minutes the whole mass is once more stirred up, and
the first process repeated. After the second solution has
been drawn off, clean water is added, and when the mass
is worked into a slurry, a plug in the bottom of the vdt
is opened and the thin slurry runoff in wooden launders,
whence it is raised and delivered away by a large
centrifugal pump. The first extensive trial on Croydon
Quartz Crushing Co. 's slimes gave : Average value be-
fore treatment: Gold, 9 dwts. llgrs.; silver, 2 ozs. 17

APPENDIX.
The former types of machines are all operated by
compressed air (or steam) and belong to the category
of the power drills.
It may be interesting to supplement these de-
scriptions by presenting some types of drilling ma-
chines of different classes, some in use on the Pacific
coast, and which have found special fields of useful-
fact remains that the turning of a crank, with re-
sistances fairly balanced by a fly-wheel, is a better
way of utilizing a man's strength than the consecu-
tive lifting and dropping of a hammer.
And then, while an experienced miner can make
remarkably good headway in hard rock, the proper
handling of the bit and hammer is only the result of
time and practice, whereas any laborer will soon
learn how to turn the crank of a hand drill with a
steady motion.
The machine here presented as a type of hand drill
is the Jackson, drill, made in Denver. Like in other
similar machines, the three essential functions of a
rock drilling tool are found.
The Leyner drill is made in Denver, Colorado, and
can generally be described as having a valve motion
and offers the most direct way imaginable. In con-
nection with former makes of rock drills of many
years ago, the writer would quote the use of
a hollow bit shank, wherein water was fed through a
hollow piston rod, this shank being permanently con-
nected to a small copper pipe inserted into an open
longitudinal groove cut out of one side of the steel
bit; the idea was to avoid the central hole in the bit,
and this arrangement does not seem to have been
adopted to any noticeable extent.
Another rock drill found on this coast is the Sulli-
van, manufactured in Chicago, and which may be
characterized as follows: Valve motion, Eclipse
type; feed, hand; rotary motion, stationary pawls,
movable ratchet, head mounted on rifle bar.

ness in other parts of the country; I refer to the
hand drill and to the diamond drill, and a few words
concerning these classes of machines will perhaps not
be out of place.
Hand Drills. — There is a two-fold idea carried
out in the construction of a hand drill; first, to utilize
human exertion to better advantage, and second, not
to make the action of the machine subservient to the
skill of the operator.
Rankine gives as the daily work developed by a
man by hammering 480,000 foot pounds, and in turn-
ing a crank 1,296,000 foot pounds, being in the pro-
portion of 1 to 2.7; and while the conditions of work
with the revolving crank of a hand drill are probably
less favorable than with a winch under a practically
steady load (the case considered by Rankine), the
of the Eclipse variety, a hand feed, and a rifle rota-
tion bar with fixed pawls and movable ratchet. This
machine differs from the other types found in the
market in several important particulars. The bit is
not attached to the piston, which is hammering on
the head attached to the shank. The result is that
the movable part of the piston can be made very
light, and reciprocate at a high rate of speed. An-
other distinctive feature of this rock drill is the use
of a hollow steel bit, through the interior of which
water under pressure is injected into the hole, a
special blowing-off attachment being provided
whereby a jet of compressed air can be directed into
the stream of water, to clean the holes from debris,
and keeping the bit's edge cool. A similar central
passage for injecting water is found in diamond drills,
valve is controlled by the main piston opening and
closing suitable ports which lead to both ends of the
valve chest respectively, where pistons of unequal
size, forming part of the valve, are moving.
The pawls of the rotary motion are here formed of
hardened steel rollers, engaging the rounded troughs
of the teeth of the ratchet wheel, light springs keep-
ing the rollers against the wheel.
This locking device is somewhat similar to the well-
known arrangement of certain makes of hand twist
drills.
Another noticeable feature is found in the arrange-
ment of the buffers, which here are made of two
spiral springs, each mounted on one of the side rods,
and alongside the front head of the machine. At the
back end, the rods are secured by two jam nuts,

separated by a spring washer. Cast steel is largely
used in the construction of the Sullivan drill, and
namely, for the shell, which is cast in one piece, no
detachable guide strips being used, and the side
wings of the cylinder being simply slipped from one
end into the rectangular-shaped grooves of the shell.
In this case, the reciprocating action of the air is
replaced by the pressure of a cam, revolved by the
operator, and which drives back the rod against a
spring whose tension can be varied at will, and which
in expanding projects the bit against the rock.
The rotary motion is produced by a rifle bar which,
in this machine, is attached to the drill rod, its nut
being stationary, and a part of the ratchet head re-
volving against stationary pawls. The feed is
effected by hand, in a manner entirely similar to that
used in power drills, permitting to vary the stroke
at will.
Rotary Drills. — In these machines the disinte-
gration of the rock is no longer produced by the vis
viva of a reciprocating mass, delivering successive
blows on the head of a sharp tool; but a cutting ring
formed, according to the hardness of the ground, of
steel teeth or of pieces of black diamond, and
secured at the lower end of a tube, is pressed
steadily against the rock, and receives a rotary mo-
tion, its action being essentially abrasive.
A number of rotary drills have been devised, their
use being more particularly well adapted to drilling
very long holes, like in sounding, prospecting, and
drilling oil wells.
The smaller sizes can drill in any direction, but a
very deep hole will more generally be vertical, the
tube being suspended, instead of resting against the
bottom of the hole. A stream of water is continually
forced down the tube, and flows out of the hole after
washing the rock at its contact with the cutting
ring, and carrying off the debris. Another advan-
tage is that a core of the various material through
which the hole is drilled can be secured and an exact
section of the traversed ground obtained.
The several types of rotary drills can be classed
under two heads, namely, heavy pressure and slow
speed, or moderate pressure and high speed of rota-
tion. The former is exemplified in the Brandt drill,
a German machine which first became known at the
Arlberg tunnel, in Austria, and which is at present
used at the Simplon tunnel, between Switzerland and
Italy.
The American machines belong to the second class,
and no more typical illustration could be offered than
the M. C. Bullock diamond drill, manufactured in
Chicago, and which is here represented.
The scope of an already lengthy article will not
permit of entering into a detailed description of the
many ingenious features found in these machines.
The motive power used to produce the rotation of
the tube may be steam, compressed air, water or
electricity, and imparts to that tube a velocity rang-
ing from 200 to 1500 revolutions per minute.
The cutting ring is pressed against the ground by
a certain amount, registered on a thrust indicator
graduated up to 5000 pounds, and maintained by an
automatic feed, acting by means either of a screw or
of a set of hydraulic cylinders. The depth varies
with sizes of holes and various circumstances, and its
largest type of machine is built by this firm under a
guarantee of boring a hole 21 inches in diameter
when a depth of 5280 feet is reached.
The latter class of machinery is distinctly Amer-
ican, and it has led to the most remarkable results
ever realized in the penetration of rocks at long dis-
tance.
Money Saving Power by Application of Blast Furnace Gas.
To the Editor : — I read under "Concentrates" of
your issue of Oct. 20th an item about the use of blast
furnace gas as fuel for gas engines. At one of the
last meetings of the "Institut du fer et de l'acier "
(Institute of Iron and Steel), Mr. Greiner, the emi-
inent general manager of the Cockerill works at
Seraing, Belgium, read a paper in which he pointed
out the saving of fuel made by using the gases of the
iron blast furnaces as fuel for gas engines, especially
for the generating of electricity. He proved that a
stack of the common type, with a capacity of 100
tons daily, produces gases sufficient to generate 2000
H. P. The Cockerill Co. mines its own coal on the
spot at a cost of $2.40 per ton, and thorough investi-
gation and close calculations have shown that by
using the furnace gas of their stacks a saving of fuel
can be made of $36,000 per annum. The company
has already ordered forty-eight gas engines which
will be fed directly by blast furnace gas. The saving
of the power that formerly went to waste is enor-
mous, as the above figures show, and this new device
of fuel is rapidly gaining favor. E. Smit.

packing, which remains stationary, considered ad-
vantageous for handling bad or gritty water ; it can
be kept tight under all conditions, and is readily ac-
cessible by removing the outside head on the pump
barrel. The lever movement is adjustable to wear by
hardened cone bearings. The suction valves are in
pockets at the side of the pump barrels so they can
be extracted without disturbing discharge valves or
any other part.
The plunger and piston rods are connected at the
center by a compression coupling, which makes it
possible to use brass rods on one end and steel rods
on the other ; either can be taken out or replaced in-
dependently. On the smaller pumps the steam pis-
ton is fitted with a steel ring, which is softer and
more elastic than a cast-iron ring and unbreakable.
The Globe Iron Works, Stockton, Cal., will send full
details on application.

Dear Sir: — We take your address from the ,
of which the subscribing attorney is a member, and know-
ing that your position enables you to furnish desired in-
formation, we take the liberty of requesting a favor which
we hope you can grant without inconvenience. We en-
close a folder prospectus, every statement of which we
are certain is correct, and speaks for itself as to its value
and usefulness, and which we request you to examine
carefully. There are doubtless many persons of the mid-
dle classes and small investors, in your locality, to whom
it is made available and who would be glad to invest in
this valuable enterprise, and we are desirous of getting a
reliable agent there to introduce the stock. The price
placed on a limited amount of stock is $15 per share, the
par value of which is $100, full paid and non-assessable.
Agents are allowed 25% commission on orders. We
would be much pleased if you would accept the agency
yourself, as a better thing for both agent and investor
can hardly be obtained ; but if your duties preclude it, we
request that you kindly furnish us the names and ad-
dresses of four or five reliable persons in your locality
who would be suitable and available persons and who
would probably accept such agency.
The kind of talk those fellows put out may be inter-
esting. They say :
" Gold has become the sole standard of values, and
its production the best paying industry of the age.
Rich deposits of gold are scarce and seldom found ;
but thinly and widely scattered almost everywhere,
its supply is conceded to be unlimited, provided it can
be economically gathered.
"This problem of its easy and profitable gathering
has been solved by the method, an entirely
new principle of decomposing the gold-bearing earth
or ore wet, in a cheap chemical solution, by this novel
application of electricity, at very small cost, and pro-
ducing most wonderful and profitable results.
" Its remarkable saving in placer dirt alone is suffi-
cient to revolutionize present gold values. Out of
many tests, probably hundreds, made upon placer in
and adjacent to Colorado, it was proven that the
present system of hydraulics does not save to exceed
2% of the gold which this method obtains. This
means that if hydraulics will gather 25 cents per ton,

this method saves in contrast $12.50. The same tests
proved that the fire assay did not indicate a value of
over 50% of the average obtained by this method
from the same material. This raises the value of all
' pay ' placer to a very good low-grade ore, and a
most desirable proposition. We give a few instances :
A sample from the Arkansas valley near Salida, Colo-
rado, assayed $10.40, while it milled by this method.

$21.60. Another sample from Goose creek, Colorado,
showed ' not a trace ' by fire assay, while it milled
$9.90 by this method. A sample of black sand from a
sluice in South Boulder creek, Colorado, assayed
$29.60, but yielded by this method $46.20. A Califor-
nia sample assaying only a 'trace,' milled $8 to $12
in very many tests. A sample from San Juan river,
Colorado, assayed $12 and milled $16.80. The same
material run over plates saved less than 25 cents per
ton, while the ' tailings ' milled only 57 cents and as-
sayed 37 cents, showing an extraordinary escape of
fine gold flowing off with the water.
' ' But the success of this method is not confined to
material carrying ' free ' or metallic gold. A test of
yellow clay taken at random from a cellar being ex-
cavated in Washington, D. C, showed $8 per ton
gold. In the State of New York, between the Mo-
hawk and St. Lawrence rivers, is a vast deposit of
sand of lacustrine origin. It contains practically no
' free ' or metallic gold, usually shows only from a
' trace ' to $1 per ton by fire assay. Cyanide will
only save about -$1 gold per ton, while this method
gets from $7.50 to $30, and has obtained as high as
$50. This deposit is a great puzzle metallurgically,
as accepted methods are valueless. It is a spur, geo-
logically, from the great auriferous formation ex-
tending from Nova Scotia across British America,
Alaska and Siberia, is inexhaustible and well located
for cheap milling, water and fuel being plentiful, and
labor reasonable.
"Again, from Maryland southward along the Ap-
palachians is a vast auriferous country, sometimes
developing ' free ' gold, but, for the most part, re-
sisting ordinary methods to gather 'pay,' but all
eligible to this method, including the rich clays and
vast deposits of talcose slates.
"It is hardly necessary to state that a process
which is so successful; in placer earths is equally so in
all ' dry ' auriferous ores, that is those containing
little or no lead, copper or zinc. We append a few
results of tests carefully made : Keystone ore,
southern Nevada, fire assay $237, our result $840 ;
Old Faithful, Montana, fire assay $5.20, our result
$16 ; Iron Sulphide, Empire, Colorado, fire assay
$21.60, our result $33 ; Astre ore, New Mexico, fire
assay 60 cents, our result $13.20 ; New Prospect,
Goose creek, Colorado, fire assay 'not a trace,' our
result $6.67. These are a few of the extraordinary
results obtained. Not all ores give such extraordi-
nary results, but the proportion is very large.
"This wonderful method, as will be seen by the
above comparison, saves gold where all others lose it,
and produces large and wonderfully profitable yields
where none before have attained pay. It is no longer
necessary to find rich deposits, but only to save what
was formerly wasted. In placer dirt, which yields
only from 10 to 25 cents per ton by usual methods, it
is common to save by this process at least $10 per
ten, and sometimes far exceeding that amount. A
mill with an output of fifty tons per day and an aver-
age yield of $10 per ton would produce $500 per day.
Subtract from this $3 per ton or $150 per day for
milling expense, leaves $350 net per day or $105,000
per year profit for 300 working days. The invest-
ment for such a mill complete would be under $50,000,
thus showing it would more than pay for itself twice
each year.
" But it is not necessary for this company to do its
own milling to any great extent. Outside capital
will be only too glad of the opportunity, and this com-
pany need only collect its royalty. This should be
moderate and reasonable, say 5% only of the gross
bullion output of the mill. This low royalty, upon the
mill above mentioned, would be $7500 per annum.
Upon 100 such mills in operation it would be $750,000
each year ; and upon 1000 such mills in operation,
which is not an exorbitant estimate for the United
States alone, it would be $7,500,000 per annum, with
no outlay save collecting the royalty alone. This is
without mentioning its use outside the United States,
while in the remaining gold-producing countries of the
world it should easily be double that of the United
States alone, or a grand total of $22,500,000 annual
royalty. Thus it is seen the proposition is one of
enormous profit from a single mill upwards and in a
field now not even attempted.
"But this is not all. By a change of chemicals
• dry ' silver ores, now seldom utilized, can be just
as successfully treated, and by changing chemicals
and electric current equally wonderful work can be
accomplished in low-grade mercurial ores.
"We have also adapted to the gathering of the
precious metals by amalgamation with mercury a ma-
chine nowise equaled by any other invention for the
purpose before made.
" All these discoveries and patents, when issued,
will be the exclusive property of the Gold
Extraction Co., and will constitute a valuable monop-
oly, the profits of which, with proper management,
are almost incomputable. It is usual in such cases to
allow large capitalists to absorb and monopolize the
benefits of such discoveries, and it never reaches the
public until it has been already largely, inflated. On
the contrary, this company has decided to allow the
public to share in the profits of its very initial pro-
motion ; and for which a limited amount of stock is
offered. This company's stock is divided into shares
of $100 each, full paid and non-assessable. It is of-
fered temporarily at a price which will make the in-
vestor a large and quick profit. This price is not to
be permanent, and the company reserves the right to
advance it at any time without notice. You can as-
certain the present price from the party furnishing
this folder, or, failing in that, upon application to the
company.
"As soon as this method is in general operation,
which will soon occur, this stock will readily be worth
par and doubtless paying a large per cent upon a
much higher valuation and become a wonderfully re-
munerative investment. It is notorious how very
valuable such revolutionary discoveries have been
and few have equaled the promise and scope of this
one." Gold Extraction Co.,

The Oil Fields of Kern County, Cal.
NUMBER II.
Written for the Mining and Scientific Press by H G. Parsons.
Sunset District. — The Sunset oil district has been
known as such for many years, and has received con-
siderable attention at the hands of successive State
Mineralogists or their field assistants. This has been
because of ample surface indications proving the ex-
istence of petroleum. Besides oil springs, there were
extensive deposits of asphaltum, and in late years a
considerable quantity of petroleum has been taken
from groups of shallow wells sunk by Jewett & Blodg-
ett in the mesa lands near the asphaltum beds. The
district is 40 miles southwest of Bakersfield, in the
foothills of the Tehachapi mountains, which form the
southern boundary of the San Joaquin valley. Prof.
W. L. Watts gave an extended description of this
district in a monograph published by the State Min-
ing Bureau in 1894. Besides describing the geology
and topography of the district, he ventured certain
opinions, which are being verified by recent develop-
ments. He stated that there are evidences of two
geological formations at Sunset, and that each would
be found to produce an oil peculiar to itself. He
located one formation in the first tier of foothills ris-
ing out of the mesa lands ; the other in the hills
farther to the southward. As has been intimated,
this opinion has received confirmation through recent
developments. An oil of greenish cast and of lighter
grade than that taken from the first wells sunk in
the district has been found south of the first tier of
hills. Already several companies are operating in
this vicinity, hoping to find the green oil in quantities
that will compare favorably with the output of wells
producing black oil in the northern part of the
field.
Lack of transportation militates against the Sun-
set district at present. It costs heavily to get freight
into the district over a stretch of 43 miles of sandy
road. It is thought the building of a railroad will not
be long deferred. A branch of the S. P. from Gos-
ford, on the McKittrick line, was projected before
there were many productive wells. Now that pro-
duction has begun in earnest, so that the railroad will
secure freight both ways, there will be every induce-
ment for a speedy completion of the line. A large
quantity of material for the road is now stacked up
at Gosford.
Another disadvantage at Sunset is lack of potable
water. The wells all yield salty or sulphurous water,
entirely unpalatable. Drinking water is hauled from
a valley in the mountains 12 miles distant, making it
expensive. It is probable that as the district in-
creases in importance this water will be piped to Sun-
set.
The interests of Jewett & Blodgett in the Sunset dis-
trict are paramount. It is largely due to the per-
sistent work of these gentlemen that the petroleum
industry holds such a prominent place as it does in
Kern county's history to-day. They erected as-
phaltum works at Sunset eleven years ago, and fol-
lowed this by sinking oil wells in adjacent mesa lands.
They have always supplied a fine grade of asphaltum,
and, when their present enlarging works are com-
pleted, they will manufacture an excellent article and
a good deal of it. They have sunk over twenty oil wells
in the Sunset district, nearly all of which are yield-
ing. Their latest well, " No. 35, " in the hills about
li miles southwest of the refining works, is probably
the best producer in the camp. Besides owning much
land in the district, part of which they have leased to
other parties, they have leased additional lands,
making them large factors in the development of this
promising field. A description of the asphaltum
works will be of interest :
Originally the company treated the crude as-
phaltum, which lay as a vast deposit on the surface
of the earth. This product was melted in large vats,
the impurities settled and the refined material was
drawn off in a liquid state, leaving a sandy residuum
which could be used as fuel. At present, asphaltum
is manufactured from crude petroleum taken from
the Jewett & Blodgett wells, or purchased from other
wells in the district. It has been found that this plan
is superior to the refining of crude asphaltum taken
from the hillsides. The present works are modeled
after those at Baku, Russia. Retorts have been
placed which will dispose of 350 to 400 barrels per
day of crude petroleum. Superheated steam under
pressure is injected into the petroleum in these re-
torts. This agitates the vapors and they pass off at
a less degree of heat than would be necessary if the
fluid were heated over a firebox. Asphaltum heated
above 400° P. will be destroyed by disintegration.
The distillate which is condensed from the petroleum
vapors is itself valuable, selling at present for 8 cents
per gallon and containing 18% of a rich lubricating
oil. This, however, must be extracted by a further
process. The residuum which is drawn out of the re-
torts after the distillation, is finished is 90% pure as-
phaltum. Such foreign matter as still inheres is of
positive advantage, being infusorial earth that tough-
ens and strengthens the product. This asphaltum,
after being hauled by team over a long road to
Bakersfield, is shipped to Eastern markets, where it
has to compete with asphaltum brought from Trini-
dad, W. I. If the Sunset product were not of superior
quality, the West India asphaltum would crowd it
out, as cheap ocean transportation and a short haul
by rail would be factors hard to combat. The General
Electric Co. of Schenectady, N. Y., The Gilsonite Pav-
ing Co. of St. Louis, Mo., and Chicago, 111., roofers
are regular purchasers of Sunset petroleum. There
is no trouble to find a market for all which may be
manufactured. The crude petroleum of this district,
specific gravity 12° B., will yield 50% asphaltum,
manufactured as above described. The engraving on
the front page gives a good idea of the appearance
of the district.
Development work in the Sunset district has been
stimulated by the operations of Easton & Eldridge,
who manage the affairs of several companies.
Sunset King, on Sec. 10, 11-24, down 900 feet, with
a little showing of oil, propose to go deep. Man-
hattan, on Sec. 11, 11-24, down 800 feet, are after
the same sand as the Sunset King. Sunset District,
on Sec. 3, 11-24, now rigging up. Bonita, on Sec. 3,

producing, after perforation of casing, twenty bar-
rels of oil per day. Sunset Petroleum & RefiniDg Co.,
on Sec. 29, 11-23, down 100 feet, have had a showing
of oil from near the surface. Sunset Consolidated, on
Sec. 28, 11-23, down 300 feet, now putting in cas-
ing.
The Monarch Oil Co. of Arizona was the first com-
pany to strike oil in the hill section at Sunset. Their
productive wells are on Sec. 2, 11-24. The first
stratum of oil sand was struck at 385 feet, the second
at 440 feet; the latter is 65 feet thick, but very rich
in oil. Wells Nos. 1 and 2 are producing, but both
are troubled with sand, which prevents steady oper-
ation of the pump. It is thought 100 barrels per day
for each well will be a conservative estimate of the
output after these wells are able to pump regularly.
The Monarch supplies many other outfits with oil,
sending it as far as to the Bay City, in the Midway
district, 12 miles toward McKittrick.
There are several wells with bright prospects in
the immediate vicinity of the Monarch. " No. 35,"
belonging to Jewett, Blodgett & Beal, has already
been referred to. It is on Sec. 35, 12-24. It is pro-
ducing as much as Monarch No. 1 and presents ex-
actly the same characteristics. The Occidental Oil
Co. of West Virginia are reaching a good depth in
their well, on Sec. 2, 11-24. A strong odor of gas is
observable. The Areola is in the same vicinity. The
rig is ready for operations, but matters are delayed
by legal complications and scarcity of casing. At the
Golden Gate, which is on the flat, sontheast of the
Monarch, a small stream of oil is pumped from the
well, probably amounting to ten barrels per day. The
Pittsburg, also on the flat and half a mile east of the
Monarch, is closed down for lack of casing. The
Superior, on Sec. 7, 11-23 (on the flat), has good in-
dications at 600 feet. The Barrett well, on Sec. 11,
11-24, obtained oil at 1400 feet, but the oil production
gave out and the well ,is now yielding water as salty
as that from the ocean. This repeats the experience
at Jewett & Blodgett's No. 17 well. The latter was
a spouter of oil for several weeks, but it now pro-
duces water carrying some oil. Another of Jewett &
Blodgett's wells on the flat supplies water for most
of the boilers in the camp. The water is less salty
than that coming from other wells, but is strongly
sulphurous. The U. S. Oil Co. are sinking a well
with good prospects on Sec. 26, 12-24, a short dis-
tance west of the J., B. & B. well on Sec. 35. Wheat
& Wilson are putting up rigs on promising territory,
Sec. 3, 11-24. The Lion Oil Co. have excellent indi-
cations on Sec. 12, 11-24. As their property is lo-
cated a little distance from the hills, operations are
watched with keen interest. They are now down be-
tween 600 and 700 feet. The Sunset Queen, the State
Crude and the Queen Esther, all in the second or
third range of hills, are thought to be in safe terri-
tory.
There are many wells being sunk northwest of the
Monarch and "No. 35," but as yet this group is the
farthest of productive wells in that end of the field.
In the southeastern part of the field the Navajo and
the Sunset Czar are both productive. The former is
in rich oil sand at 600 feet. They sold 300 barrels of
oil to other companies during September. These
wells are in the first range of hills and are located
diagonally across three sections of land from the
Monarch. Thus the oil field at Sunset has a demon-
strated length of 44 miles. The early wells of Jewett
& Blodgett, which are producing limited quantities of
oil from shallow depths, lie on mesa lands in a straight,
line between the more productive extremities, in tba

hills. The question now seems to be whether the rich
oil belt at Sunset bends to the south, corresponding
to the conformation of the hills, or whether it crosses
the flat. This question will soon be determined by
the operations of companies now sinking wells in both
localities.

Some Colorado Metals.
Baily & Monnig, who give attention to the hand-
ling of some of the rare metals, state that almost 100
tons uranium oxide, associated with vanadium, have
been shipped from the Dolores river, or Paradox
valley region. The ore is somewhat siliceous, being
found in a stratified sandstone section. Some of the
shipments ran as high as 30% uranium. The three
Gilpin county mines which are producers of this
metal are at present closed down. The production
of about 500 tons from the three mines ran about 15%
to 20%.
Within the past year a few cars of metallic bismuth
have been shipped from Leadville, the most of which
ran about 8% pure, but also, carrying gold and silver.
The Leadville bismuth occurs as an oxidized ore, be-
ing found in streaks running through bodies of other
oxidized ore and the streaks bearing it are stripped
and sorted from the other material.
Many samples of cobalt, nickel and tin are fre-
quently received by Baily & Monnig, but seldom in
quantities to be handled.
The discoveries of large bodies of tungsten in Boul-
der county have attracted much attention' among
those who handle that class of material, which is
made use of in hardening and toughening steel.

The Cross Shaft, Angels, Cal.
Written tor the Mining and Scientific Press by S. A. Hoffman.
The machinery for this shaft was furnished by the
Union Iron Works of San Francisco. The engines
are of the pocket valve type. It is also fitted with
water power, which will be used most of the time
after the winter rains set in. The cylinders are
24x60 inches. The engine is direct acting.
The water wheels (two) are of Pelton make, each
10 feet in diameter, using 500 inches of water from
running head of 380 feet, delivered through 26-inch
steel riveted pipe. The reels are of the cone pat-
tern, holding 1935 feet of U-inch plough steel cable —
seventy-five coils round the cone. The reels are
fitted with the Lane brake and are detachable ; they
can be used separately. The diameter of the cone at
the largest end is 9 feet 11 inches, center to center
of rope ; the smallest end is 6 feet 6 inches.
The crank disks are 9 feet in diameter, fitted with
strap brake, operated by hydraulic cylinder. The
diameter of the brake wheel on the reel is 13 feet
6 inches, with 12-inch face, fitted with double-acting
post brakes, operated by steam. Total weight on
three bearings which the reels rest on is eighty-five
tons. Total length of reel shaft and crank shaft,
37 feet 2 inches, made in Bethlehem, Pa., forged
steel, 15 inches in diameter, with a 6-inch hole full
length through it. It is coupled in the center with
forged steel couplings.
The engine is operated on a raised platform 5 feet
high, 8x8 feet square. The machinery is on a con-

formed, discoloring it a little, but protecting it from
further corrosion. Steam and flue gases, ammonia-
cal vapors, any of the acids, strong or dilute (except
hydrochloric acid slightly), do not affect it in any
way ; the alkalies alone affect it, hot caustic soda
solution dissolving it very quickly. Its tensile
strength is a little less than that of copper, diameter
and length being equal ; but, weight for weight,
aluminum has nearly three times the tensile strength
of copper. It is being used largely by American
electrical engineers as a bare and insulated con-
ductor for telephone and telegraph wires, and for
power, etc. It is now used as a trolley wire and by
electrical firms for commutators on account of its
light weight and non-magnetic and non-sparking
properties; for brushes and brush holders, switches
and cut-outs, for the same reason.
Pennington & Sons' Steel Works.
On the front page is a view of Pennington & Sons'
main steel works, San Francisco, in which are shown
four steam hammers — one small, one medium and two
extra large. The combined striking power of this
collection, added to that operated in their branch
works, compares favorably with any similar plant
west of the Mississippi river. This firm makes a
specialty of forging either iron or steel as desired.
They turn out forgings ranging in weight from one
pound to 30,000 pounds. Of their various manu-
factures their hammered steel shoes and dies, known
as the " Pennington," are best known. Next in im-
portance comes their shafting of all kinds, used
mainly in the construction of ships, engines, auto-
mobiles, etc. Recently they have added a depart-
ment for the manufacture of well boring tools.
crete foundation, built of crushed quartz, 12 feet
deep, and is anchored down with eighty-eight anchor
bolts, each 2\ inches in diameter, 12 feet long. The
foundations are 42x65 feet. This machinery will
carry a skip, holding 1500 gallons of water, 1400 feet,
making the round trip, fill the skip and dump it, in
two and one-half minutes.
The gallows-frame has two sheave wheels, each 12
feet in diameter, solid cast iron, running on 6-inch
shafting. The top of the wheels is 106 feet ; top of
frame 96 feet. This frame was designed by engineers
of the Union Iron Works, and was raised and framed
on the ground here by the Utica Co. It is built Of
24x24-inch pine, having four posts. It was designed
from the Eiffel tower pattern. The posts are spliced
in the center.
The steam for the engines is furnished by four boil-
ers of 75 H. P. each, of steel yV inch thick, with head
t inch. Each boiler has sixty-two 3}-inch flues.
Each boiler is 14 feet by 5. The total cost of this en-
gine and hoist was $75,000. The time required from
time of starting foundation to time of running was
six months. The total weight of lift, loaded, is nine
tons. !***"*'**
The Cross is a three-compartment shaft and is not
worked above the 700 level. The shaft is 1400 feet
deep.
For the above information I am largely indebted to
Jno. Ellis, who had charge of the building of the
foundations, and who has general supervision of the
machinery now.

Idaho Springs, Nov. 1.
(Special Correspondence). — A 400-foot
upraise from tho Knickerbocker tunnel to
tho bottom of tho Emerson shaft has just
been completed, and is regarded an inter-
esting and intricate pieco of work. Tho
shaft, which was 400 feet deep, was badly
caved and held considerable water, pre-
venting co-operation through the shaft
with work in the upraise. The upraise
was made by hand drills, was well timber-
ed as the work progressed, stations were
made at each 100 feet, and the upraise
struck squarely the base of the shaft and

LEWIS AND CLARKE COUNTY.
The Montana M. Co., in the report of
its revenue account, shows a net profit for
the half year of £9816 19s 9d. The 60-
stamp mill was in operation during the
half year and reduced 25,100 tons of ore;
the twenty stamps of the 50-stamp mill
were in operation three months, reduced
1370 tons, making the total for the half
year of 26,470 tons of ore, which sent to
the mills yielded in bullion, bars and con-
centrates (on realized and estimated re-
alizable values) $158,027.78, average $5.97
per ton. The expenditure on mining,
milling and prospecting operations
amounted to $164,359.07, equivalent to
$6.21 per ton, resulting in a loss of $6331.29,
or an average of $0.24 per ton. From the
5th of April to the 30th of June, 1900,
33,168 tons of tailings were brought under
treatment and produced cyanide precipi-
tates, realizing as per smelter's returns,
$110,820.63, average $3.34 per ton; ex-
penditure, embracing the treatment and
transport of the tailings and redemption
of cost of the tailings plant, amounted to
$50,659.48, equivalent to $1.52 per ton, net
profit $60,161.15, average of $1.82 per ton.
Compared with the previous half year the
average realized value of the product
($3.34) shows an increase of 63 cents per
ton, and the net profit ($1.82) an increase
of 60 cents per ton. In his report to the
directors, General Manager Burrell says :
" The development work has been a con-
tinual series of disappointments. At the
end of last year we found a small ore body
50 feet below the 1000-foot level in the No.
3 shaft part of the mine. This discovery
gave us encouragement to push on below,
but the ore did not extend more than 25
feet up or down. We then sank the No.
1 winze to the 1100- footlevel, and extended
the south drift 115 feet, going beyond the
ore found 50 feet above, but failed to find
any pay ore on this level. Our object in
drifting within short distances in this part
of the mine was to enable us to open for
immediate extraction any ore we might
discover, so as to keep the mill in opera-
tion. When the 1200-foot level was
reached in this part of the mine, at 17
feet from the winze, the south drift un-
dercut ore at two different places for a
distance of 20 feet each on the level. It
is here that we are making the most act-
ive efforts. South of the last point above
mentioned we encountered a fault, throw-
ing the vein 70 feet toward the hanging
wall. Following the faulting plane to the
east we re-encountered the vein, and while
it is 65 feet wide between the walls, and
not barren, no pay ore was found in this
work. Owing to our want of success here
and at other points in the mine, the 60-
stamp mill was shut down on July 15th
until such time as our development work
shall discover sufficient pay ore to enable
us to again resume milling operations."
At the head of Big Blackfoot river
there are bodies of gold-copper ore. J. K.
Waite, Sec'y Montana Copper M. Co.,
which owns the Marlinspike, W. J. Bryan,
Copper World and other claims, says:
"Although at present remote from the
railroad, the veins of that district can be
worked out at 30% of the cost involved in
Butte. They can all be developed to
great depth by tunnels; the country is
heavily timbered, being within 3 miles of
the Lewis & Clarke forest reserve, and
there is abundant water power in the
streams to operate. The principal leads
are in Mineral mountain; the summit, 9000
feet above sea level, is granite. Under
this is a belt 2000 feet deep, of copper-
bearing rock, porphyry and gneiss, sub-
divided by strata of slate. Lund Bros.,
Dickson & Nelson have driven a tunnel
300 feet on the hanging wall and crosscut
120 feet to the foot wall. The mines are
reached from Drummond by a wagon
road to Kleinschmidt flat, on Cooper lake,
to the Marlinspike."

SOUTH AFRICA.
The delay of Roberts in closing up the
Boer war has been so prolonged that
April 1st or July 1st is the best now looked
for. Gen. Roberts allowed twenty men to
enter Johannesburg for the purpose of
looking after the mines. Pumping had
been commenced at some of the mines,
but according to the latest advices this
had been stopped owing to the difficulty
of obtaining supplies from the coast. The
fact is that Roberts' forces require all the
facilities the railroads can furnish, and
the mines must wait until the armies have
returned to the coast.
A Chicago firm which has had on its
hands mining machinery for the Trans-
vaal, ordered before the war began, has

sale realized $19,500. The balance of 5000
claims will be offered for sale this month,
and, if not sold, opened for relocation.
Dawson welcomes the order of the Gov-
ernment abolishing Crown claims. In the
future claims abandoned by their owners
will be subject to relocation and will not
revert to the Crown.

Notices of Recen.. Patents.
Among the patents recently obtained
through Dewey, Strong & Co.'s Scien-
tific Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Ore Separator.— No. 660,342. Oct.
23, 1900. J. P. Smith, Denver, Colo.,
assignor of one-half to A. H. B. Harenc
and J. A. Lehrritter, of Salida, Colo.
This invention is designed to separate
heavy valuable portions of ore from their
gangue and from other associated mater-
ial as well as from each other. It consists
essentially of transversely inclined shak-
ing tables having longitudinally disposed
guides, the ends of which lie in diagonal
lines from one side to the other of the
table; slime conveyors and movable hinged
fingers at the end of the table opposite the
receiving point; intermediate between the
tables is a return conveyor which receives
the pulp from the first table and has a
movement independent of that of the
tables. In conjunction with these tables
is a mechanism for producing a shaking
movement.
Removable Ventilating Pitcher
Cover.— No. 660,370. Oct. 23, 1900. A.
Drennan, A. Smith and A. Graham, of
Bodie, Cal. This invention relates to a
device for preventing the access of flies
and insects to pitchers and like containing
articles, and a means for providing ventila-
tion for the contents and removably at-
taching the device to the pitcher, so that
they can be separated and perfectly
cleaned. The device consists of a wire
ring surrounding the pitcher between the
swell of the body and outer curve of the
top, this wire having angular bends at the
rear, and it is thence carried up over the
rear of the cover, the latter fitting the
top of the pitcher. The bends are sepa-
rated from each other to allow then to ex-
pand when the rim is to be removed, and
coiled springs encircle that portion of the
wire which extends horizontally over the
rear of the cover adjacent to the handle.
Each of these springs has one member at-
tached to the cover and another member
secured to the ring at a point between the
rear portion and the angular bends so as
to normally close the cover. An upwardly
projecting loop serves as a thumb piece
so that by pressure upon this the cover
can be lifted to pour out its contents, the
coiled spring yielding for that purpose
and acting to again close the cover as soon
as the thumb piece is released.
Almond Huller and Separator. —
No. 659,801. Oct. 16, 1900. Walter G.
Read, Colusa, Cal. This invention relates
to an apparatus for removing the hulls
from almonds and separating the hulled
nuts from the unhulled nuts, hulls, leaves,
sticks, etc., delivering the cleaned hulled
nuts into a receptacle, the unhulled nuts
into another receptacle, and the separated
hulls, leaves, sticks etc., into still another
receptacle. It consists of a cylinder or
drum, a longitudinally journaled rotary
shaft extending therethrough, means for
delivering the unhulled almonds into the
drum, beater arms fixed upon the shaft
within the drum, with radial braces or
arms in the receiving ends of the drum
having their outer ends twisted or turned
to present their edges towards the nuts
so that the latter will pass readily through
the drum. From this drum they are de-
livered upon a suspended shoe which has
means for oscillating it, and a peculiarly
constructed wire screen surface which
allows the hulls to pass through while re-
taining the almonds thereon. Other
screens and chutes are employed upon
which the separated materials are re-
ceived, and means for delivering them to
their proper receptacles.
Fruit Packing Form.— No. 660,362.
Oct. 23, 1900. S. L. Casella, Alma, Cal.
This invention is designed to provide an
apparatus for rapidly filling baskets or
packages with fruit, such as grapes,
berries, etc., which are ordinarily packed
into small veneer baskets. The apparatus
consists of a rectangular frame having
elastic metallic plates fixed and projecting
outwardly in one direction, and these
frames are approximately the shape of a
basket which is to be filled. Between the
plates is fitted a slidable block which may
be moved to the top or bottom, with
means for holding it in position. The
frame is fulcrumed in a yoke, which yoke
is fixed to the table or bench where the
work is to be done, and the frame is turn-
able to reverse it, with suitable locking
devices for either position. The frame be-
ing turned so that the plates project up-
wardly, the block or plate within the
space enclosed by the plates drops to the
lower side, and is there supported while
the space between the plates is filled with
the fruit. The basket is then inverted
over these plates, and the device being
reversed the basket is withdrawn and the
movable plate acts as a follower to press
the fruit into the basket as it is removed.
Pipe Riveting Machine.— No. 660,-
542. Oct. 23, 1900. S. Foreman, Sacra-
mento, Cal., assignor to Schaw, Ingram,
Batcher & Co. of same place. This
invention is designed for riveting large
gas, water and other pipes which are
laid in trenches, or other permanent
resting places, and joined together
to form a continuous pipe after the
sections which are usually made in the
shop are brought to the place where they
are to be finally laid. The ends of the
meeting sections are slipped one into the
other, and holes being made through
them, they are riveted by the use of a
pneumatic tool, preferably operating upon
the point of the rivet inside of the pipe.
On the outside is a holder-on or anvil
which presses against the heads of the
rivets, while the inner end is being upset
by the tool. In this invention a band sur-
rounds the pipe extending on one side
sufficiently to form a yoke to receive the
holder-on and anvil, and these are secured
to these projecting ends of the yoke so as
to stand in line with the rivet while the
latter is being headed. The device is easily
turnable so as to advance the anvil to the
next rivet and so on successively until all
are riveted and the joint completed. The
pipe thus serves to support the resisting
anvil without any exterior support. The
anvil itself is peculiarly made to extend out
flush with the edge of the outer section
of pipe and serves to close the two pipe
sections together and make a tight joint

Tooth Crowns.— No. 660,319. Oct. 23,
1900. J. F. Twist, San Francisco, Cal. This
invention is designed to form tooth crowns
and to fit and adapt them to the position
in which they are to be used. It consists
of an apparatus for primarily shaping
the crowns consisting of a series of dies,
a supporting stand, a guide fitting the
stand concentrically with the dies and
punches by which the part to be shaped
is passed through the successive dies until
the desired form and size has been pro-
duced. The punches are guided by radially
moving wings slidable in a casing and
acted upon by springs so that they will fit
any size of punch.

vention relates to improvements in gates
such as are used upon farms. It consists
of a hinged gate adapted to swing so as to
stand transversely across the road which is
to be closed, or by swinging to one side to
stand parallel with the roadway and leave
a free passage, and in combination with
such gate, a mechanism by which the gate
may be unlatched by a person approach-
ing from either side, and mechanism by
which the gate is caused to swing to
either open or close. In conjunction with
this is a latching device by which the gate
is retained in either its open or closed
position. These movements are all pro-
duced by a vertically disposed fulcrumed
lever which acts to raise the latch, tilt the
gate and cause it to swing. Connections
are made between this lever and other
levers located at the side of the road, and
at a sufficient distance from the gate so
that the approaching passenger can
operate the levers and open it.

SILVER— Per oz., Troy: London, 29Jd
(standard ounce, 925 fine); New York, bar
silver, 63Jc (1000 fine) ; San Francisco,
63Jc; Mexican dollars, 50Ac.
The London Statist says: " As the
silver in the reserve is now at an irroducible
minimum, the whole of the further de-
mand for rupeos will have to be met by
purchases of new silver. If India ab-
sorbed 60,000,000 ounces of silver in the
past year of famine, what will it require
in a year of prosperity ? The world's
production of silver is not much over
160,000,000 ounces, and India's require-
ments in the past year have been equal to
nearly 40% of the total output. From the
closing of the Indian mints until the cur-
rent year India's purchases of silver were
not more than about 15,000,000 ounces per
annum. Now we have the prospect that
the demand may be 60,000,000 ounces a
year. It will be evident, therefore, that
the Indian Government will be a constant
and large buyer of the silver and that the
price in the future will probably rule at a
much higher level than it has done since
the closing of the Indian mint."

SMOOTH- ON
COMPOUND
AN IRON CEMENT
For repairing leaks or fractures in steam or hydraulic work. When hard it will withstand a red beat,
steam, water or oil, and expands and contracts the same as iron, insuring a tight joint at all tempera-
tures. Difficult flanged coonections can easily be made with SMOOtH-ON COMPOUND, as it

Dredging for Gold.
The first elevator bucket dredger
operated in the Northwest was built
at Bannack, Mont., on Grasshopper
creek, in 1895, by H. J. Reiling and
others, was named the F. L. Graves,
was rebuilt in 189G and became suc-
cessful in 1807. That same year the
dredger A. P. Greater was built and
was a success from the start. Then
followed the dredgers Maggie A.
Gibson, Bon Acord and Geo. F. Cope,
all located on Grasshopper creek,
below Bannack. These dredgers met
with varying success. The Maggie A.
Gibson ran into poor ground, was
finally dismantled and moved to Ruby
valley, Mont. There was practically
no prospecting done in Grasshopper
creek at Bannack, the creek being
too wide to admit of tests, pitting or
drilling. A. F. Greater felt sure
there was gold there, for he had been
there since the early 60's and had
seen much gold taken out with the
rocker and sluice box in the shallow
workings. He secured favorable
ground and made considerable money.
The dredger Geo. F. Cope is now re-
ported to be a success after a year's work in changing
and reconstructing the machinery to adapt it to
handle the ground in a proper manner.
;~These particulars concerning the Bannack dredgers
are mentioned to show the necessity of careful inquiry
and study of conditions surrounding a placer prop-
erty, as well as systematic and intelligent prospect-
ing. During the past two years a number of ele-
vator bucket dredgers have been put out in other
States, and are under successful operation. The
North American Gold Dredging Co. at Breckenridge,
Colo., have two elevator bucket dredgers at work in
40-foot ground. The Boise Dredging Co. of Phila-
delphia have three elevator bucket dredgers near
Centerville, Idaho, in the Boise basin, in 28-foot
ground. These are all operated by electric power.
The Horse Prairie Gold Dredging Co. have a new
elevator dredger — the Isabel Brenner — in operation
at Horse Prairie, 18 miles west of Red Rock, Mont.
The Pacific Gold Dredging Co. of Chicago have a
large elevator dredger near Salmon creek, Idaho,
working on the McNutt placer grounds.
The Conrey Placer M. Co. of Boston, Mass.,
J. Baier Supt., have a large single lift elevator
dredger, working in Ruby valley, at the mouth of
Alder gulch, 7 miles from Virginia City, Mont., in 30-
foot ground. Two views of this dredger, the Col.
Gordon, in operation are given on this page, as built
by the Vulcan Iron Works, Toledo, Ohio.
The Boston & Idaho Gold Dredging Co. of Boston,
Mass., have operated a Risdon dredger at Idaho City
for the past two years, having met with good suc-
cess after the first few months of trial in 20-foot
ground.
There are about twenty dredgers working in Cali-
fornia, up the Sacramento valley, from Folsom, on
the Feather river, northward. At or
near Oroville there are nine dredgers,
of which five are elevator dredgers.
The new Vulcan elevator bucket
dredger is designed to be fitted with
buckets holding 10 cubic feet each, to
have capacity to dig 5000 cubic yards
of material every twenty-four hours.
This dredger will have about 300
H. P., will be equipped with modern
engine power, surface condenser, steel
gearing and sprocket wheels, steel
tumblers and bucket chains, ball-
bearing grizzly, steel sluice boxes and
electric light plant, the hull to have
water-tight compartments, length
about 120 feet, beam 44 feet, draught 4
feet. The great aim is to secure care-
ful survey of the ground to be worked
and then build a dredger suitable
therefor, to avoid the expense of
changing and reconstructing the
dredger after it has started to work,
which is always painful and discour-
aging work. A dredger that will
work successfully from the start is
the one prized by those who invest in
such ventures. Profits in elevator
dredging depend on the richness of the
ground and economy in operation.

"It is snowing hard and the prospectors are
coming in," says a letter from a Northwestern moun-
tain town. In California the prospector in many
localities can keep on through the fall and winter,
but in many of the mountainous regions of the metal
mining States his movements are governed by the
snow. When it begins to disappear from the foot-
hills in the spring he is off with his outfit and horse
or burro, and through the summer is busy. When he
starts he has mostly food supplies, cooking outfit,
and a few simple mining tools ; when he returns he
has mostly samples of ore, and the local assayer is
kept busy. He works through the winter, grub-
stakes himself or gets some one to put up for him
and starts off again ; he always sees riches ahead,
and though those riches do not always materialize,
who shall say that he does not get as much enjoy-
ment from their prospect as the weary-eyed, over-
worked city man who ofttimes has the money with-
out being able to stop long enough to enjoy a little of
it. The prospector is the best friend of the miner,
and of the man who makes mining machinery. He
creates the domain that they enter into and enjoy.
Upon his failure or success depends the prosperity
of many people. He is the pioneer in all mining
operations and is the faithful and efficient ally of
everything connected therewith.
of the mount itself. As the top of the hill is cut
away and the men go deeper into the mass of the
mount the material does not "grow rich with depth,"
as is so often said about a mine's workings, but ap-
pears to deteriorate. The average value of the ore
treated in the past year was Is 9d per ton less than
the average value of the previous year's tonnage.
Unique among gold mines is the Mount Morgan
property, Queensland, Australia. The receipt of the
annual report of the directors recalls attention to
this singular mine. Ten years ago the "mount " was
about 1600 feet high, cone-shaped, made up mostly of
finely comminuted matter. Working from the top
downward, the hill is being dug away, in its entirety,
being now cut down to about 1400 feet height. Every
ounce dug out is treated, gold being disseminated
throughout in particles even finer than in the banket
of the Rand, South Africa. During the year for
which the report was made out — June 30, 1899, to
June. 30, 1900— there were treated 239,276 tons. This
was classified as 59.20% "low-grade oxidized ore ; "
16.02% " medium grade oxidized ore ; " 11.22% "high-
grade mundic ore ; " 13.56% "low-grade mundic ore."
All the 239,276 tons averaged 15J dwts. gold per ton
— 63.34 shillings, $15.41. Out of the year's receipts
the company paid £350,000 dividends. The treat-
ment process, technically considered, has been fully
given in these columns. The supply of material to
be so treated is the measure of the cubical contents
State Mining Legislation.
The several State Legislatures that will shortly
convene have among their newly elected members
many practical mining men fully acquainted with the
needs and requirements of their constituents, and it
is probable that some beneficial legislation will result
therefrom this winter. In general it may be said, as
of other governmental functions, that men are gov-
erned best who are governed the least, and ordi-
narily the best encouragement to the miner is to not
attempt to hamper him with legislation. There are
a great many absurd rules and restrictions that vex
and annoy, and in this case, as in others, it is more a
question of needs than of suppositions. To those,
however, who realize how fast this west half of
America is filling up, how greatly the ranks of work-
ing miners are increasing, and with what giant steps
the mining industry is advancing, it will probably be
apparent how necessary are some additional legal
requirements concerning the owning and operating
of mining properties. There are a great many sug-
gestions sent in as to what is and is not required con-
cerning such legislation, and among other recom-
mendations from men who by reason of their posi-
tions and experience should know what they are
talking about, it is believed that in the interest of
the miner there are a few general measures that
might with propriety be advocated.
Among the measures proposed are the creation of
a commissioner of mines for each State and Terri-
tory, with due authority delegated to enforce sundry
legal regulations for the removal of explosives from
general supply stores in mining camps where there is
no municipal law governing the storage of the same,
or in mining camps not incorporated ; that no en-
gineer in charge of any hoisting works or who, in ad-
dition to other duties, hoists and lowers men shall be
employed to exceed eight consecutive hours in each
twenty-four ; that no one under 18 years of age be so
employed, and that any one acting in such capacity
be required to have a license properly issued by a
duly appointed board.
Regarding this last suggestion things are beginning
to run somewhat loosely. It is conceded by all that
the engineer, or call him what one will, the man who
has charge of the lowering and hoisting of workmen
in a mine shaft, occupies a very responsible position,
one that requires considerable intelligence and con-
stant vigilance, and to avert accident no one ignorant
of at least the rudiments of the requirements of such
a position should be so employed. Of all men the
engineer should not owe a position to any "pull,"
and yet it now sometimes happens, as many miners
know, that the man who has been tried in other
positions around a mine, and who has demon-
strated his inability or incapacity, is finally put to
lowering and hoisting men and in charge of the
engine. This, however, is likely to occur, only in a
small mine in an isolated locality.
In California and Montana there is a compulsory
system of mine bell signals which every engineer
must observe in those States, and is supposed to
know, though in some instances the supposition is
not warranted. This comes under the head of the
duty of the State to protect its citizens, even though
some of those citizens may object to such protection.
Some other suggested requirements are that
abandoned shafts, pits or other excavations likely to
endanger the life of man or beast be properly cov-
ered over or fenced in ; that in all shafts equipped
with two cages no engineer shall hoist or lower more
than one cage at a time ; that the speed at which
men are hoisted and lowered shall be regulated ;
that mines hoisting material from two or more lev-
els shall employ a man as eager, whose duty it shall
be to unload and attach, and give all signals to the
engineer ; that all mining superintendents make
monthly or quarterly reports to the properly consti-
tuted State institution of the condition of the mine;
that all working mines keep up a set of working
maps, both plan and section, which shall be open to
inspection by officers of the State Mining Commis-
sion, such maps to be compiled by a competent
mining engineer at least twice a year ; that local in-
spectors be appointed in the various mining camps
whose duty shall be to examine into and report upon
expenses when so instructed by the commissioner of
the mine ; that there shall be prohibited the use of
iron, steel or other metal bar in tamping ; that lad-
dered ways be partitioned off and be separate
and distinct from the main working shaft ; that
guard rails or gates be provided at station
levels ; that provision be made for leaving a pillar of
ground around the main working shaft sufficient to
insure safety ; and that an official bureau of mining
information be created, to which corporations and in-
dividuals owning mines should be required to make
regular reports.
To these and such as these will be made consider-
able objection. It is not to be understood that this
paper endorses all or any of the above suggestions.
They are just what is found in the minds and on the
tongues of a good many men everywhere throughout
the mining region, and are here given place for what
they are worth. That additional mining legislation
is necessary is manifest because of the increasing im-
portance of the industry, the greater number of men
actively engaged in mining and because of the ab-
sence in so many cases of legal safeguards. In gen-
eral, the objection to such legislation may be stated
in the expression of opinion from some sources that
it is not the business of the public nor is it the busi-
ness of the State to attempt any parental supervision
of such things, nor is it in accordance with public
policy or requirements to compel any one to make
report of his private business, or admit of its regu-
lation.
The obvious answer to such objection would be that
the State is paramount, that it is the duty of the
State to make all required safeguard for the lives
and property of its citizens and that the public have
rights that must be respected; that when a portion
of the public domain is given to any individual or cor-
poration, the development of that part of the public
domain entitles all those interested in mining to at
least a general outline of results ; that while it is not
fair to the individual to expect that he shall give a
detailed account of his private business, yet for the
general good certain fundamental data and phases of
development should be reported; that competition
can in no way inj ure the business of the gold miner
and that ordinarily where men are doing a legitimate
business there is no objection to the affording of in-
formation as to development and operation generally.
It is also probable that there will be considerable
brought up in the Legislature this winter of proposed
mining legislation in the way of State and Territorial
laws concerning the locating of claims, work thereon,
etc. Inasmuch as federal mining law is supreme in
all those cases, it is always well to have as few State
limitations as possible, and it is a matter of necessity
that any mining legislation be so fairly and plainly
presented that its passage will not be, as in so many
recent cases, the signal for universal demand for its
repeal.
Nothing Wonderful==in California.
At the Humboldt County Bank there is a gold nug-
get— a chunk of virgin gold of irregular shape and
knobby surface — whose longest axis measures 3
inches, with an extreme width of 1| inches and an
extreme thickness of 1} inches. Its weight is a little
over eleven and one-half ounces. It was picked up
on the Peterson Bar mining claim, in Eddy gulch, a
tributary of the North Pork of the Salmon, in Siski-
you county, and was sent to the bank for sale or
deposit to the credit of the owner of the mine,
C. A. Peterson of Rollins, in that county. — Eureka
Standard.
The above is from a California " country paper. "
It is an ordinary notice that attracts little attention.
But if such a "chunk of virgin gold " were " picked
up" at Nome, or Tierra del Puego, or some other
far-off region of eternal ice and night, what a furore !
How it would be photographed, and what columns
would be written about so wonderful a nugget of
gold ! But in California it is just a common, ordinary
eleven-ounce nugget, worth probably $200 or so,
" picked up " in a placer claim, given a few lines in
the local paper and taken as a matter of course, the
same as the trees or the climate.

The calculated flame temperature of average coal gas

The silver on an electro-plated plate wears off in a

IN a zinc-lead ore carrying iron sulphides there should
be no serious difficulty in separating the latter by con-
centration, there being considerable difference in the
specific gravities, and it is on this matter of difference in
specific gravity that all ore concentration is based.
Most men in putting on a new hoisting rope, flat or
round, pass it through a bath of hot lubricant — a bushel
of freshly slaked lime to a barrel of coal tar is a recom-
mended mixture. If pine tar is procurable, tallow can
be used instead of lime, as there is no acid in pine tar.
"Clearance" in an engine means all the steam space
between the valve and cylinder and between the cylinder
head and piston when the latter is at the end of the
stroke. Piston clearance is the distance the piston clears
the cylinder head when the crank is on the dead center.
About 1,500,000 tons sulphuric acid were used in the
United States last year. Of this amount 50% was used
in the manufacture of kerosene, 35% in the manufacture
of fertilizing material from phosphate rocks, 15% in the
arts, galvanizing iron and steel, and dynamite manu-
facture.
Cripple Creek, Colo., is the greatest gold mining
center in the United States ; Butte, Mont., has probably
the largest number of residents actually engaged in
mining of any one American city ; Houghton county,
Mich., has about the greatest developed system of mining
of any county on the continent.
Whether a steam engine will work better in the rain
or the sunshine is a difficult question to determine. It
is manifest, however, that the drier the weather the
more liability there is to boiler scale, for in times of
drought the water is drawn from lower levels, impreg-
nated with mineral, in wetter seasons from surface or
soft water.
In nearly all forms of metal mining the British colo-
nies in the South Pacific are prominent. As types may
be mentioned: Mt. Morgan, gold mine; the Broken Hill
Proprietary, silver; the Bischoff, tin, in Australia; the
Mt. Lyell, copper, Tasmania. The Hartley & Riley,
dredging, New Zealand, instances the profit in placer
propositions.
Flat wire hoisting ropes are in favor on the Corn-
stock, Nev., at Butte, Mont., in Tintic district, Utah,
and two or three other localities. Round ropes are in
more general use. Flat ropes range in width and thick-
ness from 2Jx 3-inch to 9xJ-inch. A round steel or iron
wire rope, to hoist a 5000-pound load, should be not less
than 1-inch diameter.
The advantage of a compound over a simple engine is
chiefly the reduction in cylinder condensation, thus mak-
ing it possible to expand the steam to a lower pressure
without loss, and, therefore, with a gain in power, thus
enabling the compound engine to develop more power
with the same weight of fuel, or the same power with
less fuel than the single-cylinder engine.
Regarding the silver yield of the Butte, Montana,
copper mines, the silver deposits were developed mostly
north of the west end of the copper area, where in
former years large quantities of silver were produced.
In the copper produced from the ores of the copper area
about 3% of the value is in gold, and the average propor-
tion of gold to silver by weight is ^Jo to 3J0.
The "bucking and snorting and refusal to start" of
the gas engine may be due to moisture in the cylinder,
which often prevents regular ignition till dried by the
heat of several explosions. By shutting off the water
jacket a few minutes before stopping the engine, and not
turning it on again till after the engine begins to ex-
plode regularly when again started, the difficulty may
be obviated.
"Displacement" refers to the quantity of liquid
displaced by the immersed hull of a vessel, and "ton-
nage " to the freight-carrying capacity of the ship, de-
termined by certain rules of measurement. The dis-
placement of a vessel is the entire weight of the hull
with all its contents, as a floating body displaces a weight
of fluid just equal to its own weight. A ship sinks in
the water to such a level that the pressure of the fluid
displaced exactly counterbalances the weight of the ship.
Next to the Rio Tinto of Spain, which has produced
copper ore for nearly 2000 years, the oldest producer of
copper in the world is probably the Falugrufva mine,
near the town of Falum, in central Sweden. The mine
is first mentioned in public records in the year 1220,
A. D., but is much older than that. The oldest privilege
belonging to the mine is from King Magnus Ericcson,
and is dated February 24, 1347. The ore contains 3%
copper, but has proved profitable.
In " Concentrates " in the issues of Oct. 6th and Nov.
3rd, 1900, were directions how to make sodium amalgam.
A Breckenridge, Colo., miner writes: "The sodium
amalgam must be freshly made to be effective. If kept
long it oxidizes. Metallic sodium may be kept in wide-
mouthed bottles covered with coal oil. Enough for a
single cleanup can be made in a small frying pan. A
small quantity of mercury from a fresh flask is poured
into the pan and dried with a sponge and then heated
beyond the boiling point, but not enough to volatilize the
mercury. A piece of sodium is cut into J-inch cubes and
the mercury taken out in the open air. A cube of so-
dium is placed with tongs in the center of the warm mer-
cury. A flash follows; a small portion of mercury is
volatilized and another cube of sodium is placed with less
flash. This is repeated three or four times, when the
sodium sinks down gently. At the proper moment a
solid mass of amalgam will appear in the center. The
contents of the pan are then stirred, and a few more
added cubes change the whole to a mass of crystallized
sodium amalgam."
Linemen say that in setting telegraph and telephone
poles remove the earth around the poles 2 or 3 inches
from the poles and about 3 inches deep, and pour a gal-
lon of tar oil around it, so that the pole is tarred just
above and just below the surface of the ground, and
then put back the earth. In southern California the
earth is dug from around the poles to the depth of a foot,
and about two gallons crude oil having been poured in
and allowed to settle and soak, the earth is put back
again and tamped. In some localities the Bell Tele-
phone and Western Union companies, using large round
poles, dig narrow channels from 2 to 3 feet deep around
the poles and fill the channels with rock salt for surface
preservation.
One advantage of a power pump and a driven well in
connection with a good heater is that all of the pumping
must he done before the engine is shut down, which
means that exhaust steam is passing through the heater,
and no cold water can reach the boiler. An injector is
convenient in such a plant, because it may be run to fill
up the boiler after the engine is shut down. In many
places this is a necessity, because boilers cannot be filled
up as they should be at night without causing water to
be thrown over into the engine cylinder and causing
trouble there. The water from an injector is always
warm, but if a larger one than is actually necessary is
secured a valve may be placed in the suction pipe, and
as the water supply is throttled the delivery becomes
warmer, which is better for the boilers.
In the case of Jordan et al. vs. Duke et al., rendered
by the Supreme Court of Arizona, April 16, 1898 (53 Pac.
Rep., 197), it was held that "when parties located a min-
ing claim, but did not work thereon to hold it until
December 31st, when they went on the claim and worked
that day and the next five or six days of the succeeding
year, and then abandoned the claim without having per-
formed all the work required by the statute, other par-
ties who made a location of said mine on the first day of
the year, before the prior locators had stopped work,
acquired no rights thereby, as they should have waited
until the prior locators abandoned their work, and, the
land at the time of their location not being subject to
location, their acts cannot relate back to when it became
subject thereto by reason of such abandonment."
In the location of a mining claim the discovery cut
and stakes are monuments, but a record of a mining
claim "calling for its own discovery cut and its own
stakes is defective when it contains no reference to a nat-
ural object or permanent monument to fix the locality of
the claim." (McEvoy et al. vs. Hyman, 25 Fed. Rep.,
596.) Where the notice calls for its own stakes and for
adjoining claims may be good if such claims are found on
the ground with definite corners and boundaries. (Rus-
sell vs. Chumasero, 4 Montana Rep., 309.) In the case
of Drummond vs. Long, 9 Colorado Rep., 538, the lode
was described as being on the southwest side of Mount
Hardin and in Portland gulch, and about 1500 feet north
of the Hawk Eye lode, and the court held that this ref-
erence located the lode generally, but was not that defi-
nite location, by reference, which the statute contem-
" Concentrates" was in error in the issue of No-
vember 3rd in a statement regarding the mining law of
Mexico. Article 5 of Title I of the present Mexican min-
ing law says: " The title of all mining property * * *
shall be perpetual and irrevocable, provided that the
federal tax * * * is duly paid." Article 22 of Title
IV says: "* * * In all other respects the owners of
said properties shall enjoy complete liberty of industrial
action and shall be allowed to work their mines in the
manner which may be more suitable to them, or to
hasten, delay or suspend the labors, employ the number
of laborers which they may deem best or concentrate
their efforts in one place with preference to other. * * "
The annual tax is $10 in Mexican silver per claim of a
square of 100 meters on each side, payable in advance
every four months in three equal amounts. There is no
tax on the output or earnings of a mine; but in case of
taking the ore or bullion out of Mexico, an export duty
is levied.
All coal deteriorates or decays to a more or less de-
gree by disintegration or crumbling, and also by the
gradual combustion of the volatilizable element. Atmos-
pheric oxygen is absorbed and converts the hydro-
carbons into water and carbonic acid. It has been
proved in one case, according to Clarke's "Rules, Tables
and Data," that bituminous coal, after having been ex-
posed for nine months, lost half its value as fuel ; coal
exposed for three months to a temperature of 284° F.
lost all its hydro-carbons. The coke manufactured from
coal thus deteriorated is inferior to coke made from coal
freshly mined. The decay of coal proceeds more rapidly
in hotter climates ; dryness is unfavorable to the change,
while moisture accelerates it. When sulphur or sul-
phurate of iron is present in considerable quantity in
coal which is changing under the action of the air a sec-
ond powerful heating cause is introduced, and both, act-
ing together, may produce spontaneous combustion. The
presence of sulphur or iron pyrites, if in considerable
quantity, is sufficient to excite combustion.

The Oil Fields of Kern County, Cal.
NUMBER III.
Written for the mining and Scientific PSess by H G. Parsons
MoKitteiok District. — The McKittrick oil district
is located in the Coast Range mountains, southwest
of Bakersfield, with which it is connected by a rail-
road 48 miles long. The railroad was built before
there was much development of the petroleum inter-
ests of the locality. Although petroleum was known
to exist there, by reason of oil springs in the hill-
sides, it was the asphaltum deposits which induced
the building of a railroad. Vast deposits of this
material — which is nothing but petroleum with its
volatile gases liberated — tempted enterprising men
to take commercial advantage of the natural condi-
tions here existing. A refinery was established, and
asphaltum was shipped in great quantities, it was
mined from veins, like coal, or taken from flat beds
where the petroleum had exuded from the ground
and was left as a dirty residuum. A small settle-
ment sprang up, called Asphalto, where the works
were situated. The refinery was run until last No-
vember, when a majority of the stock was absorbed
by a competing company, and the works were closed
down. It is doubtful if they will ever be reopened,
at least so long as the supply of petroleum holds out,
for a better article of asphaltum is now made from
crude petroleum than can be mined from the ground,
and the distillates obtained by the latter process
more than offset the increased expense of manufac-
turing the superior article.
The town of McKittrick is distant 1 mile from
Asphalto. There is an asphaltum bed back of Mc-
Kittrick, and in it deep trenches have been cut.
There is a constant seepage of petroleum into these
trenches, and this is pumped out every few days. At
another place in the canyon, a short distance north
of McKittrick, there is a stream of crude petroleum
oozing out of the soil and flowing sluggishly down the
hillside. At places along this flow one can pick up
chunks of pure asphaltum.
It is not surprising that in a locality abounding in
such evidences of the existence of petroleum wells
sunk into the heart of the earth should tap the foun-
tain head and produce oil in great quantity. The
wonder would seem to be that this work was not
pushed more thoroughly years ago, as at Sunset,
where the surface indications are hardly as great.
W. J. Berry and associates were the first successful
developers of oil in the McKittrick district. Two or
three wells had been sunk in 1892-93 by the Buena
Vista Oil Co., but the production never exceeded
twenty to thirty barrels per day, and this was sup-
posed to be seepage oil. Messrs. Berry and associates
leased land from Italian owners in San Francisco and
from the Kern Valley Bank, and in February, 1899,
began the sinking of wells. Their lease with the Ital-
ians was to extend for six years, with option to pur-
chase in three years at $200 per acre. With the
Kern Valley Bank the lease was to run for ten years,
with option to purchase at $225 per acre within five
years. The royalty while the lands are under lease
is to be one-eighth. Mr. Berry, W. M. Spencer,
T. L. Keller, W. I. Roberts, Clarence Berry and Mil-
ton McWhirter formed several companies, the best
known of which is the El Dorado. These companies
have sub-let a large part of their holdings to the
S. P. Co., to Dabney Bros. & Miley, to the Kern
River Oil Co., to the California Standard Oil Co., and
to the Giant Oil Co. They are receiving a larger
royalty from each of these companies than they pay
to the original lessors, and at the present rate of
production they will not only be able to buy the land
with the proceeds of their royalty, but may become
oil magnates without turning a hand toward further
development. They own or control some of the rich-
est oil lands in the State of California.
The place selected by the El Dorado Co. for their
first wells was near one of the asphaltum deposits.
Other local indications of petroleum were plentiful.
The company merely went deeper than some of the
earlier workers in the district, and they were re-
warded by striking oil sand from which the petro-
leum forced itself over the top of the casing. The oil
belt in this immediate vicinity is hardly more than
1200 feet wide, as has been demonstrated by dry wells
sunk outside of those limits. The trend of the belt is
northeast, and, so far as can be judged, it grows
wider in its northward course. It has already been
defined for a distance of 3 miles in a northerly direc-
tion, and extends from the hills at least into the mesa
lands adjoining. Whether it can be traced far into
the flat remains yet to be determined. In a south-
erly direction from the El Dorado wells the conditions
are also uncertain, as there have been several fail-
ures to locate the underground stratum along a line
in conformity with the uortherly trend. The limits
and direction of the trend must be decided by trial,
as no geologist or expert can settle such matters as
unerringly as does the drill of the well borer. It is a
"hit or miss " proposition with the best of them.
The Southern Pacific (or Treadwell) Co. have five
producing wells at McKittrick, one of which flows
steadily, the others intermittently. There are pumps
on each of these wells, as in most cases a well will
yield more by pumping than if left to flow naturally.
This has been an exception in the case of a so-called
"gusher." The average depth of the S. P. wells,
which are located in the best part of the McKittrick
field, is 650 feet. The stratum of oil sand is 250 to
500 feet thick. The total yield from the company's
six wells is 300 barrels per day.
The Dabney Oil Co. , who lease from the El Dorado
Oil Co. , have four producing wells, one of which is
probably the best producer in all of Kern county. It
was a great gusher when first struck, and has flowed
constantly since, though with intermittent force.
Two other of these wells are intermittent flowers. If
anything happens to the pumps the oil soon boils over
the top of the easing. The total product of the Dab-
ney wells is 600 barrels per day. The company were
perforating three wells at the time of my visit, and
had four rigs at work drilling. Their operations are
characterized by much energy, and they have given
new life to the district. Dabney Bros, and E. J.
Miley compose the company.
The California Standard Oil Co. is a close neighbor
to the Dabney, and they also own land in the north-
ern part of the field — 200 acres in all, mostly along
the supposed oil belt. They have two producing
wells and one drilling. Their output amounts to 110
barrels per day; tankage capacity, 10,000 barrels.
This company make an excellent showing for the one
year in which they have been operating at McKit-
trick.
The Kern River Oil Co., who are also fortunate
enough to be in the productive belt, have three pro-
ducing wells, another on top of oil sand at 800 feet,
and a derrick built for still another well. The prod-
uct is variable, as the wells flow or yield intermit-
tently. At times they produce 400 barrels each per
day. One of the Kern River Co. 's wells is the best
producer yet struck in the northern part of the field.
The Giant Oil Co., in the northern part of the field,
have two producing wells.
The McKittrick Oil Co., also in the northern por-
tion of the belt, struck oil sand at 700 feet, and are
now 200 feet in the stratum ; are preparing to sink
another well.
The McKittrick Consolidated, in the same locality,
struck oil sand at 850 feet.
The San Francisco & McKittrick Oil Co., north-
west of the McKittrick Co., have one producing well ;
bored a second, but injured their casing, so aban-
doned that, and are now sinking a third.
The Pacific Crude Oil Co., located in the hills in
the northern part of the field, are in oil sand and
will soon have a producer.
The Del Monte is in the same locality; are now in
oil sand, but on account of trouble with casing are
not producing.
The Belmont is located next to the McKittrick &
San Francisco ; now drilling.
Toward the Temblor district, some miles to the
north, are several ventures. The Adirondack is
drilling. The Gould & Central is down 800 feet, in
soft oil mud, from which a seepage of twenty barrels
per day can be obtained.
In the Temblor district itself four wells have been
completed or are in oil sand, while four more wells
are in process of drilling.
The McKittrick district is the seat of considerable
activity, and promises to be a great producing sec-
tion. Five carloads of oil were shipped the day I
visited the camp, and that is said to be the amount
usually sent out.
Leaching Copper Ores.
At the Petoskey mine, northern Arizona, the ore
occurs in a blanket vein and yields 12% copper, two
ounces silver and $1.80 gold per ton. The formation
is siliceous, of volcanic origin, the copper occurring
in green and blue carbonates, silicates and sulphides.
Ordinary methods of leaching do not properly reach
the silicate of copper, hence the special process em-
ployed at the new plant on the property. The
method which has been resorted to consists in fine
pulverization, especially shaped, self-dumping digest-
ing vats of prepared wood to resist the chemicals, a
solving solution to solve both copper and silver, but
immediately precipitating the latter. Some iron
will also go into the solution if any be present in
the ore.
The prepared chemical solution is made to wash
out the copper from the first digesting vat of pulver-
ized ore ; its chemical energy is exhausted by passing
it through successive vats of ore until desired result
is attained, when it is diverted to the precipitation
vats or cells containing metallic iron, specially ar-
ranged and electrically connected with cathodes of
copper, by which the copper in solution is electrolyti-
cally deposited, ready for market.
The chemical solution, having first united with the
copper in the ore, leaves it in the precipitating cells
by uniting with the iron, flowing first through these
cells as an iron solution to large, shallow cisterns or
wells, where, on cooling, crystals of iron salts are
formed. These are retorted and the combined chem-
ical recovered, to be used again in the solving of the
copper from the ore. The iron, also specially treated,
is used again.
The silver, having been left behind with the ore in
an insoluble condition by the chemical solution used
to extract the copper, is now treated with a hot,
saturated solution of common salt (the ore having
previously been washed by water to recover the
chemical solution), whereby the silver is taken up
and carried from the ore to the silver precipitatory
vat, where, on cooling, most of it is deposited as
chloride. The brine, being used only for this pur-
pose, is pumped to a higher vat, ready, on reheat-
ing, to be used again.
The gold yet resides with the ore, which is now
dumped from the vat, and, by suitable conveyor, dis-
charged into a specially devised amalgamating appa-
ratus and the gold retained, while the pulp is passed
away to the dump.
Primitive Mining Methods in the Philippines.
Native mining is primitive at a gold mine in the
Benguet district ; the mountain is seamed with
quartz veins from a few inches to 5 feet across, all
said to be gold bearing ; yet the Igorrote miner has
never got beyond the oxidized ore of the surface. He
takes an iron pike — a simple stick, shod with a steel
point 6 inches long — and with this strikes and pries
out blocks of disintegrating rock. Perhaps during
his working period, which seldom lasts more than two
hours a day, he detaches twenty to forty pounds of
quartz, which he carries down the gorge to his home
for the next operation of crushing. A miner suc-
ceeds, by weeks of this labor, in letting himself into
a burrow 10 feet at the most, and then only takes the
trouble when the vein is rich, as it necessitates his
burning a torch, prepared by the women from thin
sticks of resinous pine, which every few minutes
smokes him out. A writer says one is disappointed
at this method of gold mining and the seams of quartz
suggest possibilities for a small stamp mill ; but the
next stages of crushing and abstracting the gold en-
tirely overcome a progressive mind. From behind a
thin shade of boughs, near the houses below, rose a
thud, thud, stopping now for an instant, and then
taken up again monotonously. Peering behind the
screen one discovers an old hag, wrinkled and dried
by threescore years of a toilsome life, swinging to
and fro from the hips, in her squatting position on the
ground, and with her outstretched and rigid arm
rocking a slightly cylindrical stone of fifty pounds
upon another, larger in size and slightly concave.
Between the faces of these two stones is crushed
the quartz. The big pieces are first smashed into
lumps as large as a walnut by volcanic boulders, and
then these are taken, one at a time, and crushed to
coarse dust under the primitive arrastra described.
The fairly uniform coarse dust is then fed between
the rocking stones, and finally comes out after hours
of patient labor as an impalpable powder.
The men are lazy, but the poor old women will sit
for hours moving this crusher back and forth, spread-
ing the grinding quartz into new positions with a
dexterous swish of the hand, and then, after a day's
labor, will have but a scant ten pounds of powder
ready for the last operation of "panning."
The panning is done principally in calabashes, or
the half shells of big gourds. The powder is placed
in the calabash, which is then filled with water. A
circular motion is imparted to the water, which starts
all the lighter dirt in motion with it.
At each turn of the pan a portion of the water is
swished over the edge, carrying out the bulk of the
dirt by the time the first water is exhausted. By
the addition of water several times and repetitions of
throwing it out by rotary motion, nothing but the gold
and black magnetic iron ore is left in the bottom of
the pan. A still more careful washing takes place in
some localities by the use of a second smaller dish,
and the iron ore is finally removed, after drying, by
the use of a magnet, but in some of the regions to the
far north, where the Igorrotes are even more primi-
tive than those of the Benguet district, the black
sand containing gold is packed in small tubes of bam-
boo and sold in this condition at the seacoast to Ilo-
cano and Chinese traders for a song.
What surprises the average American is the total
absence of practical machinery for mining, and then,
again, that if there are actually valuable mineral
properties in the Philippines they have not been ex-
ploited and developed long since by the Spaniards
and foreign residents of the islands. There seems to
be but one possible explanation for this commercial
inactivity, and that lies in the defective Spanish laws
relating to mining and the development of mineral
wealth, which made it possible for the title to min-
eral lands to revert at any time to the Crown.
No one could possess a known valuable claim with-
out being ruined by Spanish officials, who demanded
hush money. No one could import mining machinery
without attracting the Government's attention to the
fact that an enterprise was about to be established in
which the Government might have the lion's share ;
hence there has been a paralysis of mining indus-
tries.
The writer referred to says he has not seen a flume
in any portion of the mining region he traversed,
though there are miles of deep black sands in the
narrow river bottoms which might pay if sluiced out
and amalgamated. They have not even got as far as
miners' cradles.

Classifying Crude Oils.
At the Petroleum Congress, held in Paris during
the Exposition, a paper by Prof. S. F. Peckham, on
the "Classification of Crude Petroleum," shows the
importance to the commercial world of the scientific
treatment of the subject. Prof. Peckham states that
in the earlier oil days no attention was paid to the
composition of different productions of crude, and
shows how the commercial value, in consequence, was
injured.
Scientists were at work on the subject of petro-
leum at a very early date, but Prof. Peckham says,
up to 1855, -rock oil" had been regarded by both
geologists and chemists as a species, and Prof. Sill-
man in that year was the first person to observe the
destructive distillation of petroleum. In isiis, after
making tests with Pennsylvania and California petro-
leum, Prof. Peckham made known the results of his
test toC. M. Warren, an expert petroleum chemist,
and was laughed at when he stated that the two pro-
ducts differed in their bases.
''When I assured him," says Prof. Peckham,
" that by passing gases through Pennsylvania and
California petroleum, that would deprive them of
hydrogen, I could evaporate the first and convert the
second into asphaltum, he was incredulous, and
thought my ideas regarding the origin of petroleum
theoretical, without any substantial basis of fact to
rest upon.
"Although I had no absolute proof thereof, I was
firmly convinced that the California oils consisted of
hydrocarbons containing less hydrogen than was
found in those of Pennsylvania.
"When, in 1880, I was engaged in collecting the
statistics for my report on petroleum to the
Tenth Census of the United States, I en-
countered two significant facts : First, the
investigators of Russian petroleum had discov-
ered that the hydrocarbons that made up the
bulk of Russian petroleum were not paraffins, but
additive benzols ; second, a correspondent reported
that the refiners of California petroleum were not
making an illuminating oil that could be sold in com-
petition with Eastern oil, but were sending their
products to Mexico, where they found a less critical
market than in California.
"This evidence pointed to sharp distinctions in
petroleums from different localities. The wells first
struck in Oil creek and the Alleghany river pro-
duced a petroleum easily refined into naphtha, illu-
minating and lubricating oils ; and, while the evolu-
tion of the technology of these oils required many
years, the movement was along certain well-marked
lines, wherein no obstacles were encountered to con-
tinued success. The process of cracking, discovered
by Joshua Merrill while working on the distillates
from coal, was applied with great success to the
Pennsylvania oils; but attempts to apply this method
of distillation to the California oils' did not produce
corresponding results, although distillation under
pressure did increase the yield of light oils.
" This discovery revived in my own mind the con-
viction, formed many years before, that the petro-
leums of the Pacific coast were specifically different
from those of the Mississippi valley, containing dif-
ferent hydrocarbons and requiring different treat-
ment for their success and manipulation. This con-
viction led to renewed attempts on my part to per-
suade the owners of large interests in California
petroleum to have made a careful and thorough ex-
amination of their crude material, with a view to de-
termining the chemical constitution of the oil, the
nature and value of the products, and the best
methods of securing these products by treatment.
These gentlemen still remained unconvinced of the
value of such work."
Prof. Peckham offers a system of classification,
arranged on the basis of chemical composition alone.
" If it is urged," he says, " that such a system is too
intricate for the petroleum exchange, and that com-
mercial differences exist among the petroleums and
other forms of bitumen, I insist that commerce has
assumed a lofty intelligence above the scientific
world, of which the latter can take no account, be-
cause there are no points of contact between the two
spheres of human activity. There is, however, a
limit to this divergence of interest that appears
when a petroleum chemist is called upon to examine
petroleum from a new locality."
There are now four types of commercial petroleum
that rank in commerce relatively as follows :
First. — Paraffin petroleum.
Second. — Russian petroleum.
Third. — Sulphur petroleum.
Fourth. — Nitrogen petroleum.
" The differences in these crude oils may certainly
be regarded as specific, and they have been estab-
lished upon the results of very elaborate analytical
researches. Perhaps for commercial purposes the
bestowal of specific names upon these varieties would
not be understood or appreciated, but for the pur-
poses of the laboratory they might be. There is,
however, in view of the knowledge we now possess,
one aspect of this question that can well be consid-
ered and definite action by it urged by both the ex-
perts in petroleum and their clients. This aspect is
the extent to which the expert or the client is justi-
fied in recommending or demanding an examination
of a specimen from a new locality, which shall be
made by the elaborate, analytical methods emp
upon the researches on petroleum conducted during
the last ten years.
" A crude petroleum is not necessarily determined
as belonging absolutely to either of these types, but
it must, 1 think, approximate one of them. It there-
fore becomes of importance, not only from the stand-
point of pure science, but that of commercial utility
as well, to ascertain from the most careful examina-
tion the composition and relation of the various com-
pounds that constitute the sample under considera
tion. This course, while involving more time and
expense, is in the end both more economical and more
satisfactory than the time-honored expedient of dis-
tilling a pint from a glass retort and dividing the
distillate into fractions of certain specific gravities,
but of unknown composition."
What is being done in refining oil in California is
referred to in an article on page 520 of the issue of
November 10th, descriptive of operations in Sunset
district, Kern Co., Cal.
The Lunkenheimer Automatic Injector.
The Lunkenheimer automatic injector, herewith
illustrated, is guaranteed by the manufacturers.
The body is cast iron, the tubes of a special hard
bronze composition made expressly for the purpose.
These tubes do away with spill holes in the walls ; the
internal areas of the tubes are smaller than some
others, for capacities claimed to be equal.
The external appearance of the injector is pleas-
ing, as the entire surface is heavily enameled. The
steam, suction and discharge connections are pro-
vided with male unions. The joints where the unions
connect to the body are made with seamless copper
rings forced into grooves cut into the faces of the
body part of the injector (see sectional cut. These
injectors will operate under the following range of
steam pressure and lifts with the feed water at 75° :
Lifts 2 to 4 feet, at 9team pressures 20 to 180
Lifts 4 to 8 feet, at steam pressures 25 to 165
Lifts 8 to 12 feet, at steam pressures 30 to 140
Lifts 12 to 16 feet, at steam pressures 50 to 120
Lifts 16 to 18 feet, at steam pressures 60 to 100
Lifts 18 to 20 feet, at steam pressures 70 to 90
With steam pressures at 60 to 100, and feed water
at 75°, the capacity of this injector can be graded
over 50%.
Further information will be furnished on applica-
tion by the Lunkenheimer Co., Bank building, Den-
ver, Colo., or Cincinnati, Ohio.
A writer in the Australasian Ironmonger says :
" I saw a man unpacking some American merchan-
dise the other day, and, being a patriotic individual,
I exclaimed : ' Hello, where do these come from ? "
' America,' said he. 'Cheaper than English?' said
I. 'No.' 'Better?' 'No.' 'What's the reason,
then ? ' ' Americans pack better, parcel better,
label better and usually send out plenty of printed
matter.' There are more ways than one of advertis-
ing; this is an excellent way."
Protecting Shaft Timbers When Blasting.
Written tor the Mining and Scientific Press by J. p. munger,
Supt. Harvard G. M. Co., Jamestown, Cat.
Having had considerable experience in shaft build-
ing on the mother lode, I have had the same trouble
in protecting my shaft timbers when blasting that
doubtless all other mine managers have had. In
hand drilling we have but little trouble when proper
care is taken ; but when power drills are used it is
extremely difficult to timber close to the work, as
often has to be done in unsafe ground, without the
danger of shooting out or damaging our timbers when
blasting, and more especially when the electric bat-
tery is used.
Experiencing some trouble in this line, I conceived
the idea of covering the timbers with a steel plate.
It struck me so forcibly as being a good plan that I
put it into use as soon as I could make my plans and
have them constructed. If our battleships can be
protected by the use of steel plates, why not protect
our shaft timbers from the deadly shot of the miner
in the same manner ?
Not knowing of any one using a device of this kind
before me, I gave it the name of " armor plate."
As mining men, we are certainly under obligations
to our neighbors and fellow workmen for any and all
pointers, coming from whatsoever source, as the ex-
perience and experiments of others inure to our
good. Consequently, I contribute this simple device
and my experiments for the good of the readers of
the Mining and Scientific Press.

side of plates, so that inner side will be smooth to fit
timbers. In putting plates together, have bottom
plate extend through or under side plate, or, better,
setting edgewise on top of bottom plate. It will re-
ceive a harder shot with less damage in this way.
Use good weight angle iron, and put rivets about 4
inches apart. The bottom plates (B) are constructed
with round or slotted holes to receive hanging rods.
The slotted holes are perforated, as it will allow for
any variation that might occur in boring the holes in
timbers for hanging rods, and cause no delay in plac-
ing armor plates in position.
The end plates are constructed with the bottom
plate (B) the full width of the shaft timbers when
together. The inside plate is cut proper length to
fit between the wall plates and put together with
angle iron, the same ■ as side plates, cutting angle
iron the length of plate (A) only. The side plates are
quite heavy, but can be raised or lowered by use of
cable, or, when timbering platforms are in place,
they can be handled quite, easily by hand. We found
they could be handled much quicker and easier than
the old plank of bulkheads, and when- we removed the
plates we found our timbers in as nice condition as
when put in, and we worked for months at a time
without injuring a timber, and no loss of time or ma-
terial retimberiug. In sinking a three-compartment
shaft 750 feet we wore out two sets of these armor
plates, which cost us less than $100 in San Fran-
cisco. Any foundry can construct to order, or the
same can be built at any mine where a power drill is,
in use.

Some Questions Answered.
The following are of the class usually answered in
" Concentrates," but seem to require the publication
of the question as well as the answer :
A man here hag a water tunnel and a pipe line on a
piece of mineral land, but has made no filings or record
of any claim of rights. A second individual has found
mineral near the water tunnel and has made a regular
mining location and claim of 1500x600 feet, including
tunnel and portion of pipe line, and has also done assess-
ment work and recorded the same. Can the second
party claim the water in said tunnel for mining and mill-
ing purposes ? The water at present is being piped to
the town and sold to consumers.
Cherry Creek, Nev.
On this subject " Lindley on Mines " says : "Min-
ing locations made upon the public lands must be
made subject to any easements therefor lawfully ac-
quired and subsisting, and held for the purposes of
conducting water over them. * * * * The miner
who selects a piece of ground must take it as he finds
it, subject to prior rights which have an equal
equity."
It is to be said, in general, that any land to which
any claim or right of others has legally attached does
not come within the definition of " public land," and
only public mineral land can be entered under the
federal mining law.
I am looking for a stone called magnet stone — not lode-
stone; comes 1 inch thick; varies from 10x10 to 10x20
in size; very fine, porous, light in weight and dark steel-
gray in color. I have been referred to you by several in
Nevada, California, Colorado and Utah. I think it was
mined in Nevada.
Philadelphia, Pa.
The inquirer has probably been reading the Sunday
newspapers and illustrated " science " articles there-
in. The gentleman from Leisenring, Pa., who wants
further information regarding the "mountain of
quartz in San Bernardino county, Cal., which was re-
cently entirely transformed into a mountain of gold
by a great electric discharge," seems equally unfortu-
nate in his selection of " scientific " reading.
Will you please consider the following problem in con-
centration of silver-lead ores ? The ore is galena carry-
ing gray copper, which in turn seems to carry the sil-
ver. The gangue matter is heavy spar, or barytes.
Analysis shows the ore to run: Silver, 19 ounces; lead,
13.7%; silica, 43.9; BaSO.,, 23.9. In order to effect sepa-
ration from the barytes we have found it necessary to
grind to 40 mesh. By doing this and concentrating at
the rate of 4.25 to 1 we save 99% of the lead, but our tail-
ings assay 17.50 ounces silver. The gray copper and the
baryteB seem to pass off together. Our neighbors, who
have quartz instead of barytes, have the same difficulty
in attempting to Bave the silver.
Colorado Springs, Colo.
Such ore as this would probably come under the
head of an ore subject to a double treatment. In ores
of that character the silver that is not susceptible to
concentration is very often susceptible to cyaniding,
and by cyaniding the crude ore first and then con-
centrating the tailings have been produced good re-
sults. It is almost entirely a question of the ore,
and one can only tell by continuous experience. Of
course, the ore would have to be cyanided by the con-
tinuous process.
This whole subject was thoroughly treated in a
series of special articles written for this paper that
appeared in the issues of March 3, 10 and 17, 1900.
A man runs a tunnel into a mountain, presumably for
water, and at the distance of 200 feet strikes quartz and
locates a mining claim. Can he use this tunnel, which
he made previous to the location of said claim, for the
$500 of development necessary to secure a patent ?
Wallace, Idaho.
Only work or development done after the date of
location of a mining claim can be legally credited or
applied to the amount of work necessary to be shown
to entitle the locator to patent.
1. How many strictly silver-producing mines do you
know of in the United States that are being worked at a
profit under the low price of silver ?
2. Do you know of any new silver district that has
been opened up since 1893, or for some time before
that?
3. Is there any increase in the production of silver
since that time, and, if so, does it keep pace with the in-
creased demand ?
4. Do the copper mines of Butte, Mont., and the lead
mines of the Cceur d'Alenes produce as much silver per
ton of ore at depth as they did at surface ?
5. Would the opening of China increase the demand
for silver to any great extent ?
6. With silver as a commodity and no new district
having opened, how long do you think it would 6tay at
the present low price ?
7. Would you consider it a good investment to buy
silver property now, at a reasonable price, that would
pay a fair profit with silver at $1 per ounce ?
Phillipsburg, Mont.
The above are interesting questions that are not all
susceptible of accurate reply.
Which is the most efficient, stamps weighing 1050
pounds each and dropping 9 inches ninety per min-
ute, or stamps of same weight dropping 7 inches 110
per minute. We run all our material through a
breaker which reduces it to 1 inch, and aim to have
about 1 inch of the same under the stamps.
Dutch Flat, Cal.
We have now in type an article covering this and
similar questions regarding stamp milling of gold
ores, that we expect to publish about the first issue
in December. It is the most elaborate discussion of
stamp milling of gold ores that has appeared in five
years.
I am trying to utilize the exhaust of a power drill, so
that I might get rid of the drillings made by the drill,
either by suction or other ways, without the use of
water, so that these drillings would not be constantly
pounded up and choke the hole up; but the face of the
drill might be against the rock to be drilled continually.
Certainly there is a great deal of valuable power going
to waste in the exhaust of a drill that should be utilized
in some such way. It would make a remarkable differ-
ence in the capacity of a power drill and the power
used.
Aspen, Colo.
It is universally conceded that these machines are
wasteful of power ; but this is accepted as an un-
pleasant, yet unavoidable, necessity. Two conditions
will always bave precedence over all others in the
matter of machine drills : They must be powerful,
i. e., do much work under reduced size, and the,'
must be simple. Of course, if they could at the
same time be of economical use, it would be a desir-
able and important feature. Tandem compound cyl-
inders, with successive expansion of the air, would
furnisb a solution in this direction, but would make
the machine heavy and intricate. Early cut-off in a
single cylinder would reduce the force of the blow.
The only promising attempt made, so far as we know,
consisted in reheating the air before its admission
into the machine by inserting a row of oil burners be-
tween the air hose and the valve chest. The pres-
sure would then remain the same, but the volume
could be increased from 40% to 50% at a very slight
cost. This, however, was apparently found impracti-
cable, as this process never progressed beyond the
experimental stage. As to making the escaping air
do some useful work of any kind, it necessarily
amounts, in whatever shape it is done, to throttling
the exhaust port, and creating a back pressure
detrimental to the power of the blow. In a familiar
way it would be, to some degree, equivalent to keep-
ing an obstruction very close to the exhaust opening,
which, of course, would not be calculated to improve
the work of the machine. Our correspondent is right
in condemning the uneconomical escape of a cylinder
full of air at a high pressure, at each blow of the bit,
but it is believed that in reducing the power absorbed
by the machine he would also diminish its effective-
ness.

Pyritic Smelting in the Black Hills.*
Pyritic smelting, so-called, as practiced in the
Black Hills is pyritic smelting only in the sense that
Dr. John Percy uses the expression in his "Metal-
lurgy of Silver," where he describes a process for
smelting dry silver ores in connection with iron
pyrites, to form a regulus.
The ores treated by this process in the Black Hills
are very siliceous, averaging about 74% of silica,
from 10% to 20% of oxide of iron, 4% or 5% of alumina
and from 2% to 4% of lime.
In 1889, while dean of the South Dakota School of
Mines, I took up the question of their smelting.
There were neither copper nor lead ores in the Hills,
hence pyrite and pyrrhotite, of which there are large
deposits, were employed to form a regulus. This
mixture of pyrite and pyrrhotite, besides being abso-
lutely barren of gold and silver, carried an average
of 30% of silica. The only basic material available as
a flux for the great excess of silica in the ores and in
the flux was a dolomitic limestone. Moreover, the
local coke gave 24% of ash, 60% of which was silica —
as unpromising a set of conditions as can well be
imagined.
We had before us the examples of W. Lawrence
Austin of this Institute, who had experimented at
Toston, Montana, and of Dr. Bartlett, now of Can-
yon City, Colorado.
The whole literature of the subject was studied,
and the situation at Kongsberg, Norway, seemed
to be nearest our problem ; but at all places
where pyritic smelting was followed one factor
stood out prominently : the slags were always
very siliceous, carrying about 50% of silica. We
could not reduce them to any very definite formulas.
They did not resemble any of the typical lead smelter
slags, nor did they always hit the oxygen ratio of
any definite or recognized silicate. The best slags
for the process were apparently those which, as Kerl
expresses it in his Metallhuttenkunde, approached a
bisilicate ratio.
The slags which we found best for our material
approached a bisilicate ratio, if alumina was figured
as an acid (as is done at Mansfield), but more nearly
the sesqui-silicate if alumina was considered as a
base.
Table I gives the widest variations of slags made
during my administration. I have also calculated the
oxygen ratio.

In Table I the slags given under date of July, 1894,
were made in an experiment with pure limestone.
They were not so satisfactory as those made with
dolomite. Their oxygen ratio probably gives the
real reason.
It was seen very early in our experiments that
iron for flux was out of the question, and that, save
the little that the ores carried, we must rely upon
lime and magnesia as bases. I was acquainted with
the Mansfield slags, in which the iron sometimes falls
as low as 4%, while the alumina may reach 15%.

Tempering Drills.*
I find that in order to make a good drill it requires
close attention from start to finish.
I sharpened thirty-seven drills for a contest awhile
ago, and this is the way I did it : I worked with a
low heat, and at the very last I pounded the face of
the drill over and over, first on one side and then on
the other side, until it was black or showed no heat ;
then put it in the fire just long enough for it to show
a slight color, and then pounded it in the same man-
ner as before, and so on, several times.
At the time I did this last work upon it, I never
struck it once on the edge ; if it was too large, I
ground it off ; then, before chilling, I put a nice finish
on the drill.
In hardening I heated the drill to a nice cherry-
red, taking a long heat of about 3 inches. In taking
this heat I always kept the drill moving in the fire,
and towards the last had scarcely any blast on.
Just before taking it out of the fire I shut off the
blast entirely, and then I plunged it in water and left
it until thoroughly cold. I then polished it bright.
To temper I gave several old drills a long heat,
and laid my drill on top of these, letting it project
over about 2 inches, taking about fifteen minutes to
temper, drawing to a straw or nearly a copper, and
laid it down to cool without putting it in the water.
I treated all the drills in this way and not one of
them broke, although they were used in Gunnison
granite with an eight-pound hammer. A miner who
saw them used stated that he had seen drilling con-
tests in Leadville, Denver and Butte, but never saw
chisel-shaped bits stand the racket as these did.

Cost of Coal.
The price of coal at the pit's mouth varies a good
deal in the different centers of production. The low-
est point appears to have been touched in British
India, viz., 92 cents per ton, while the dearest coal is
met with in the Cape Colony, where the pit's-mouth
price is $3.56 per ton. The corresponding price in
Natal is much less, viz., $2.50 per ton. Coal can be
obtained at the pit's mouth in New Zealand for $2.50
per ton ; in Tasmania for $2 per ton; in Victoria for
$1.79 per ton, and in New South Wales for $1.39 per
ton. Transvaal coal costs $1.91 per ton at the pit's
mouth. The United States ranks next to British
India as a cheap coal-producing quarter, the aver-
age price at American pit's mouths being $1.15 per
ton, though on the Pacific coast, and in California es-
pecially, it runs as high as $7 per ton. As regards
European countries, the cheapest coal would appear
to be available in Spain, where the pit's-mouth price
is only $1.52 per ton; Austria comes next with $1.53
per ton ; Great Britain third with $1.62 per ton ;
Russia fourth with $1.68 per ton, and Germany fifth
with $1.84 per ton. The average pit's-mouth price
in Belgium is $2.05 per ton. France figures to still
less advantage with an average of $2.17 per ton.

The Smidth Ballmill.
On this page appear three illustrations of the
Smidth ballmill, originally designed and used for re-
ducing materials from a lump state to the market
fineness in one operation. This involved the use of
outside screens which bolted the material to the re-
quired fineness, and in the case of material like Port-
land cement clinker, where extreme fineness, such as
95% through 10,000 meshes per square inch, was de-
manded, the output of the ballmill was relatively
type A ballmill. This machine has a through-shaft
with journals running in bearings at both ends, and
consists of a drum with two end plates (c), between
which the curved drum plates (d) are fixed. These
plates do not form a cylinder, but one end of each is
set a few inches towards the center, forming steps.
The balls and materials tumble over these steps,
when the drum revolves, the pounding action of the
balls being designed to be increased thereby, the
steps allowing residue from sieve to be caught and re-
enter drum. The curved drum plates are protected
on the inside by thick steel plates (e) which are di-

small, though its low horse power, slow speed and
slight cost of repairs made it more economical than
buhr stones or the then popular ring and pendulous-
head type of machine. But immediately after the
invention of the tubemill, the ballmill was made use
of for preliminary crushing only, its product being

vided into several sections, so that each section can
be separately renewed. The lining plates are fixed
by means of bolts. The end plates (c) are also lined
with thick plates (cl).
The grinding plates have rows of perforations (f)
through which the crushed material constantly falls
on slotted steel screen plates (g).
Whatever is fine enough to pass
these screen plates falls on the
inner sieves (1), coarse and strong,
that which passes through these
falls on the finishing sieves (k).
The material passing through the
finishing sieves is collected in the
lower hopper-shaped part of the
dust casing (m) surrounding the
drum, and from this falls to a
for brushing the sieves. The top half may be removed
for repair of the drum.
Fig. 3 shows the type B machine, the same as A,
except that the shaft, instead of going through the
feed-hopper, is stopped short inside the drum and
there fixed in a spider, the external part of which
runs on a roller bearing. By means of this arrange-
ment lumps up to 10 inches each way can be fed into
the mill, and the feed opening itself at the same time
is reduced in diameter, which allows a heavier charge
of balls to be used.
Fig. 4 shows the automatic ballmill feeder for the
ballmill, which is attached to and operated
from it. About 90% of these ballmills in
operation are being fed with these auto-
matic feeders. The apparatus illustrated
is made and furnished by F. L. Smidth &
Co., 66 Maiden Lane, New York City.
The Power Behind Nature.
Dr. Carpenter once wrote an essay on
"The Power Behind Nature," in which
he compared the production of the various
natural phenomena of the external world
to the working of the machinery in a large
and well equipped factory. In this factory
hundreds of wheels are kept in operation
in one immense room by a system of bands,
which connect them all with a common
source of motion. That common source is
simply a revolving beam. But there is
nothing in the room that could turn it.
Evidently, it must be connected with some-
thing outside that is invisible inside the
room. Going outside, one finds what,
perhaps, strikes him as an easy solution
of the problem. The beam is turned by a
huge wheel, which, in its turn, is moved
by a constant stream of water. But what
is that which feeds the unfailing sources
of this stream 1 Well, the whole process —
as far, at least, as science can follow it — is
traced at last to the sun, which lifts the
water, in the form of vapor, from the sea,
and returns it as rain, or hail or snow
to the land. There, indeed, is the power
outside the factory that turns the wheels
within. If the motive power were steam,
instead of running water, this answer
would still hold good. The power, the
the energy is in either case derived from
But the sun is part of a system, and has
had a beginning in time. Speculative astronomy at-
tempts to account for its origin by the theory known
as the nebular hypothesis. This theory, however,
points to no absolute beginning. To explain the mak-
ing of the solar system it assumes conditions that
are still left unexplained. The mind of man, after
science has said its last word, is left to look for
" the power behind nature."

In the issue of the 10th inst., in the fifth and con-
cluding installment of the admirable article by
Mr. A. E. Chodzko of San Francisco on " Mine Rock
Drills," there was an unfortunate transposition of
the matter which disarranged the natural con-

passed to the tubemill for fine grinding or pulveriza-
tion, this system demonstrating further reduction in
the cost of grinding.
The Smidth ballmill is stated by its makers to be
the result of practical experience in using the origi-
nal idea, the objectionable features of the earlier de-
sign having been eliminated and the maximum of
convenience for access and repair developed and ar-
ranged. To meet the demand for several forms of
the ballmill, the makers have designed types classi-

conveyor or elevator, or may be dropped direct
into the containers. The outlet of the dust casing is
provided with a slide gate.
The residue from the sieves, coarse and fine, is car-
ried up with the mill, until it falls through large holes
in the curved part (1) of slotted steel screen-plates
and together with residue from these falls into the
drum again through the steps. In one of the end
plates a man-hole is fitted and in the dust Casing a
door corresponding to the man-hole, giving access to
the interior of the mill. The dust casing is made in
three parts, a small section being easily removable

styled "Appendix " should have followed, instead of
preceding, the reference to the types of machine
drills mentioned therein.
The richest countries in the world are where min-
ing is prosecuted most vigorously. The poorest coun-
tries are those where there is no mining. The richest
men in the world are and always have been great
miners, from King Solomon down to the Rothschilds
and Rockefeller, who are now largely interested in
mining gold, silver, copper, lead and nickel.

FREMONT COUNTY.
(Special Correspondence). — The import-
ance of Florence as an ore reduction cen-
ter is increasing. The National and El
Paso chlorination mills are operating on
150 and 100 tons per day, respectively, the
Metallic (cyanide) running at the rate of
about 300 tons per day. The chlorination
plant of the Union Gold Extraction Co. is
one of the most modern in existence and
will be in operation before Jan. 1st. Its
capacity is about 500 tons. A technical
article descriptive of this property will be
furnished the readers of this paper a little
later. W. B. Milliken is manager and John
E. Rothwell Supt.
The new cyanide plant of the Dorcas
M., M. & D. Co. is rapidly nearing com-
pletion. Its capacity will be 125 to 150
tons and will be a custom mill. The ore
will pass through a 10x20-inch Blake
crusher, thence to ^-inch mesh crushing
rolls, thence through an automatic sam-
pler, and is then conveyed by belt con-
veyors and distributed to ten V-shaped
ore bins, having fifty-five tons capacity
each. The material then passes through
the cylindrical drier of the usual pattern,
thence through screens and fine crushing
rolls, which prepare it for the roaster,
which is of the Holthoff-Wethey type.
From the roaster the material is delivered
to hoppers above the cyanide leaching
vats, through which it is distributed, as
required, to the vats. The vats are of
steel, six in number, size 4x30 feet. They
will be equipped with a pneumatic device
for supplying air through the pulp. The
precipitating room and bullion furnace are
being well arranged on a floor below.
The usual vacuum tanks for di'a wing off
the solution and the sump tanks to catch
the exhaust are provided. On the lower
floor is a row of eight Wilfley tables. The
pulp passes from the vats through agitat-
ing tanks to the tables for concentration.
To obviate the harmful effect of dust and
also as a saving device, dust collectors are
being put in on the crushing floor. After
the roast a certain per cent of lime is
added by means of Janin's automatic ore
feeder. This company is made up largely
of Boston and Cleveland people, J. M.
Hower being manager and Louis Janin
Supt.
The cyanide and chlorination plants
handle Cripple Creek ores that run from
$10 to $40 per ton — none that run below
$10. As greater depth is gained in Crip-
ple Creek mines, an increasing percentage
of sulphur is observed. At present the
ores may he said to average 2% sulphur or
over, the silica running about 58% to
60%.
Some four or five months ago the mills
made a reduction of treatment charges,
and they now stand at $6 to $9 per ton de-
livered at the mills, the railroad rate be-
ing $1.50 to $3 per ton from Cripple Creek
to the mills at Florence, Cyanide and Col-
orado City. The $6-dollar charge at the
mills is on ore running J-ounce and below;
the $9 rate being on ore running from 2
ounces up to 5 ounces gold.
The Rocky Mountain Smelter, being
erected at Florence on plans prepared by
Dr. R. F. Carpenter, will be a general
smelter — that is, it will handle ores from
all sections. The plant is built of struc-
tural steel, supported by heavy retaining
walls of masonry, and includes two 36x180-
inch furnaces, with two Connellsville
blowers and two engines and three boil-
ers. By Jan. 1, or sooner, this plant will
doubtless take its place as one of the
potent factors in the field of applied met-
allurgy.
The old Beam mill, now in the hands of
the Florence M. & R. Co., is being
changed and repaired with the idea of
using the Beam roasting furnaces and ap-
plying what is known as the continuous
system of cyanide treatment, with some
features of amalgamation and concentra-
tion.
Manager John Jacobs of the El Paso
Reduction Works states that the ore
handled by that plant, amounting to 3000
tons per month, will average $25 per ton.
A feature of the National is the concen-
tration of the refuse after chlorination by
ten double-decked tables, by which, Man-
ager J. R. McDonald states, a saving of
40% of the values left in tailings after
chlorinating, is made.
All the Florence plants are equipped to
use crude petroleum as fuel for the roast-
ers, though they are also equipped to use
coal. The consumption of this grade of
oil product keeps up to the limit of pro-
duction most of the time. When coal is
used, the better grade is obtained, as the
operators say they do not find much
economy in using the cheap grade of
slack.
The reduction . works at Florence,
Cyanide, Colorado City, Victor and Crip-
ple Creek, including those nearing com-
pletion, will have a capacity of nearly 3000
tons of ore per day, 'or 90,000 tons per
month, which is a greater tonnage than
the district ever has produced; anditmust
be conceded that the Denver and Pueblo
smelters will continue to get a consider-
able share of the district's output. But
this abundance of reduction facilities must
be regarded as favorable to the stimula-
tion of ore production. The transportation
facilities for reaching the reduction works
with district ores are reaching a point of
excellence hitherto unequaled .

On the California, Leadville, in eight
months the company has erected a surface
plant, has sunk shaft 530 feet, has cut two
stations and put pumps therein, and has
done considerable drifting. Sixty feet of
shaft was sunk through dolomite.
The Home M. Co., Leadville, has put in
a new fuel plant on the Penrose, to cost
25% less than that in ordinary use. It is
a gas produced by pumping air through
heated petroleum which carries with it
one part of hydro-carbon gas to nine parts
of air. At the Penrose boiler house five
air-tight steel cylindrical tanks, 10 feet
high by 5 feet in diameter standing on
end, have been erected. Coiled steam
pipes in these heat petroleum to 185° F.
and hydro-carbon gas is thrown off. Air
is then forced through a finely perforated
false bottom, and, passing through the
oil, carries with it the gas, which com-
bines with air and is carried off to fire
boxes under boilers. The tanks now be-
ing put in will be of 400 H. P. and will
supply fuel for four large boilers at the
Penrose and one at the Starr shaft.

The report from Salt Lake City to effect
that T. A. Rickard, while there, an-
nounced that sale of the Camp Bird had
been concluded for sum of $6,500,000, is
denied by Mr. Rickard, who wires from
New York: "The statement quoted by
The Times was entirely unwarranted. I
said at Salt Lake City that the deal was
still pending and that the original price
was $6,500,000."
C. Newman, of Durango, is developing
the Mono group, near Red mountain,
Ouray. He has opened up a body of iron

that for November is estimated at 15% in-
crease over that of October.
The Independence T. & M. Co., locally
known as the Hull City, will increase its
production, and the same is reported as
to the Isabella. In general, it may be
said that by Jan. 1, 1901, the big mines of
the district will be in condition to work
steadily and at their greatest capacity;
every existing condition indicates a pro-
nounced increase of ore tonnage for next
year. The year 1900 will be noted for the'
numerous consolidations and for the large
expenditures made for new equipment
and betterments about the leading mines
of the district, with result that the prin-
cipal producers of the camp have to-day a
class of boilers, hoisting engines, air com-
pressors, electrical machinery, shaft
houses and ore houses and other equip-
ment that takes rank with the best in any
part of the world.
In an article written from Florence, in
this issue, the growth of milling facilities
at valley points is noted. In this con-
nection it may be predicted, with some
degree of certainty, that there will he no
more mills or reduction plants erected in
Cripple Creek district. The disadvantage
of operating them here, as regards water
supply, fuel and other conditions, has
been demonstrated, especially as custom
plants. The largest mill in the district is
the Economic and that is designed to
operate solely on ores produced by one
group of mines.
Despite the fact that the tendency of
the mills is to have their own sampling
works, the public sampler is and likely
will continue to be a factor in the district.
At present there are four or five of this
class operating within the district.
Among these the Rio Grande handled for
October about 7000 tons, which will be in-
creased for November.
The Oneida mill, not proving a success,
has been abandoned and will be disman-
tled. Wascott.

MISSOULA COUNTY.
Missoula says: "This is the busy time
for the mine owners, who have to perform
their annual representation work. The
number of affidavits that have already
been filed with the county clork and re-
corder show that hundreds Of dollars'
worth of work has been performed. All
the old prospectors and minors are now
being employed. Owners of mines who
reside in other parts of the country secure
all the idle men in this section to perform
the work, and, as a result, very few idle
miners are now in the city. Most of the
work that has been performed so far this
year has been in the district along the
Cceur d'Alene branch. Judging from the
affidavits already filed, the country is full
of miners, who are rushing the work,
that it may be finished before the cold
weather sets in. The class of work that
is being done depends on whether the
mine is a quartz or a placer mine. The
owners of placer claims in a majority of
instances in their affidavits report the
building of new sluice boxes. One or two
have reported that several miles of this
class of work have been done this
summer."

Obituary.
MARCUS DALY.
Marcus Daly of Anaconda, Mont., presi-
dent Amalgamated Copper Co., and one of
the leading mine owners and operators of
the country, died in New York City on
the 12th inst., in the 59th year of his age.
A native of Ireland, he had been for
twenty-five years a resident of Montana.
He was manager Alice mine many years
ago, and, later, came into prominence in
connection with his copper holdings and
the big mining and political fights with
W. A. Clark. In the copper mining in-
terests of Montana nearly every one was
either a Clark or Daly man, and the suc-
cessive victories or defeats of either fac-
tion made constant stir, while the magni-
tude of the financial interests involved
lent considerable importance to the strife,
to stockholders in the East.

Notices of Recent Patents.
Among the patents recently obtained
through Dewoy, Strong & Co.'s Scien-
tific Press U. S. and Foreign Patent
Agency, the following are woi thy of spe-
cial mention:
Automatic Weighing Scale. — No.
660,794. Oct. 30, 1900. E. Hanak and
George Hoepner, San Francisco, Cal., as-
signors to Union Scale & Manufacturing
Co. The object of this invention is to pro-
vide an automatic weighing scale, in
which there is an oscillating tilting com-
partment, a weighing bucket movable
with relation to a fixed discharge, so that
the compartments are alternately filled
and discharged. Latches are provided for
holding the bucket in either position to
which it may be tilted, and means for dis-
engaging the latches after the bucket is
filled. The invention also comprises a
u rangement of feed or supply hop-
per.
Weather Strips for Doors or
Windows.— No. tiii0,83ii. Oct. 30, 1900.
.1. K. Bundy, San Francisco, Cal. This in-
vention relates to a device for hermetically
closing the bottoms of doors, windows or
the like against the entrance of wind, rain
and snow. It consists of a movablo tilting
strip forming a continuation of tho thresh-
old or seat over which tho door normally
closes and so guided that when the door is
closed the inner edgo of the strip will be
tilted upwardly against tho lower edge of
tho door and form a joint with a molding
of suitable cbaraetor which fits across the
lower part of the door for that purpose-
When the door is opened this piece falls
by gravitation to its normal position
where it forms a part of the threshold.
Devices for Collecting Finely
Divided Minerals and Slimes.— No.
060,844. Oct. .10, 1900. W. E. Darrow,
Sonora, Cal. This invention relates to an
improved apparatus for concentrating and
collecting high-grade mineral. It con-
sists of submerged inclined surfaces, upon
which the mineral is concentrated, means
for precipitating and eliminating the
hoavy waste gangue, while the line parti-
cles in suspension How on with the water
and may be collected in reservoirs for
futuro treatment. It comprises a sta-
tionary tank having surfaces inclined to-
ward the longitudinal sides, so that the
heavy material will slide therefrom and
the lighter material will collect thereon.
Means are provided for supplying water
from below to fill the tanks and submerge
the surfaces, and means for supplying ma-
terial to pass through the tank and over
the surfaces. There is a discharge at the
opposite end, and a transversely corru-
gated or channeled bottom having open-
ings through it, discharging into a closed
receptacle which is also filled with water,
so that the heavy sediment gradually
passes through the openings into the
lower compartment without agitation in
the upper compartment.

From Brazil comes a statement illustrating in a
variety of ways the value of technical education, and
also illustrating incidentally what personal push will
do. A young man had drifted there from an East-
ern city, and, though desirous of employment, found
little encouragement in the town where he had de-
termined to stay. The situation was discouraging,
when the municipal authorities there concluded that
they would install an electric light plant and utilize
an adjacent water power. They wanted an electrical
expert to examine plans, make estimates, come to
this country and get the needed machinery, and the
fact having been mentioned to the young man, whom
we will call Smith, he at once announced himself as
a first-class electrical engineer, though, as a matter
of fact, he knew no more about electricity than elec-
tricity did about him. However, on the strength of
his own recommendation and self-assurance, the Bra-
zilian authorities engaged him, and with a New York
draft for needed expenses he sailed for the North on
the next steamer. Immediately upon his arrival,
he began a special course of study in electrical
engineering, besides attending a night school for the
same line of instruction. Besides his assurance he
was also endowed with considerable physical strength
and staying power, and stood the double strain for a
month, by which time he had sufficient working
knowledge of the matter to enable him to attend
to his errand. He bought and brought back the
machinery to the Brazilian town and is at pres-
ent installing it to the satisfaction of all concerned.
This is the story as given, and it sounds as if it might
be true. The incident is in no wise commended nor
commendable ; but, without prescribing or proscrib-
ing such action, it is cited as characteristic of the
qualities that often push men to the front.

California Miners' Convention.
The ninth annual convention of the California State
Miners' Association assembled at Golden Gate Hall, San
Francisco, on the morning of the 19th inst. The dele-
gates were welcomed in an address by the Mayor of the
city. The Credentials Committee reported delegate
representation from the several counties as follows :
San Francisco 57, Butte 26, Calaveras 24, Alameda 20,
Santa Clara 7, Nevada 60, Placer 58, Los Angeles 6, San
Diego 2, San Bernardino 1, Kern 19, Inyo 1, Plumas 11,

San Luis Obispo 5, Santa Barbara 5, Napa 1, Sonoma 4,
Trinity 1, Siskiyou 1, Madera 1 ; also, from the Sacra-
mento Chamber of Commerce 5, University of California
1, California Petroleum Miners' Association 14, South-
west Miners' Association 5, San Francisco Chamber of
Commerce 5, Stanford University 1, Fresno Chamber of
Commerce 5, Los Angeles Chamber of Commerce 5,
honorary delegates, Senators and Congressmen 9 ; a
total of 505.
The president read his annual address, dealing with all
the questions that have been before the consideration of
the Association during the preceding year, welcomed the
delegates from the California Petroleum Miners' Asso-
ciation, who were for the first time represented in the
State Miners' Association, and went into the history of
debris legislation concerning the hydraulic miner at con-
siderable length. He expressed belief that the mineral
lands bill would pass at the next session of Congress, rec-
ommended the building up of county branch associations
through the State, and suggested that the Association's
secretary be paid a salary. He showed that the Califor-
nia State Mining Bureau should be maintained under the
regular appropriation bill instead of depending for the
necessary funds for its existence on the biennial caprice
of legislators. President Ralston made a fine address,
which was received with applause by all present.
Secy. Benjamin and Treas. Hendy reported, showing
an increase in membership and $3,208.65 in the treasury,
with all bills paid. The receipts during the year were
$11,215.41; disbursements, $8,006.76.
Two of California's newly elected Congressmen —
Coombs and Woods — made addresses.
The first committee report was from the committee on
legislation and was read by Chairman Jno. F. Davis of
Amador county. It said in part that the committee ad-
heres to the proposition laid down by it at the conven-
tion in 1899 and that the remedial legislation with refer-
ence to the law of mining, in almost all its phases, should
be amendatory of existing Federal law, rather than inde-
pendent statutory enactment at the hands of the Legis-
lature. The law will lose nothing of directness and effi-
cacy thereby and the uniformity so much desired will be
promoted. The present mining law of California is,
roughly speaking, the Federal Lode law of May 10, 1872,
and the Act amendatory thereof, the whole being codified
in Sections 2318 to 2346, inclusive, of the Revised Stat-
utes of the United States.
The salient features of the sections referring to quartz
mining are contained in Sections 2319, 2320, 2322 and
2324, and the legislation recommended to Congress by
the committee refers to amendments of three of those
four sections. The committee recommended that these
sections be amended in three particulars: In the pro-
visions concerning the marking of the exterior bound-
aries on the ground; in the provisions concerning the
local rules, regulations and customs of miners and State
and Territorial statutes on location of claims; and in the
provisions concerning annual assessment work.
In the requirements for the marking of exterior
boundaries upon the ground, under the present pro-
visions of the law, the rights of the discoverer of a vein
are not fully protected. Unless he be given a reasonable
time to mark his boundaries upon the ground, either
under a State statute or a local rule or the decision of
the Supreme Court of the United States, he may make
many mistakes vital to his interests. As a matter of
fact, the trend of the California decisions on this point
is against him, though at the same time against the
trend of the decisions of almost all the other States and
Territories except Oregon. The committee recom-
mended to Congress an amendment to Section 2324 in
this respect, drafted upon lines analogous to those in
the late State statute repealed in 1899.
Concerning the second point referred to by the com-
mittee, the recognition in Federal statutes of local rules,
regulations and customs of miners and State and Ter-
ritorial laws concerning location of claims, Chairman
Davis cited Judge Beatty to the effect that the whole
subject of mining locations is an extremely simple one,
which may easily and therefore ought to be regulated
by one general law, the terms and existence of which
shall be established by public and authentic records and
not left to be proved in every case by the oral testimony
of witnesses or by writing contained in loose papers or
memorandum books, such as are often dignified by
the name of mining records. The tainting
of every mining title in the land at its very inception
with the uncertainty which results from the actual or
possible existence of rules affecting its validity, perfectly
authentic evidence of which is nowhere to be found, is a
stupendous evil. Experience has demonstrated that such
an uncertian state of the law is a prolific source of litiga-
tion and no experience is required to convince any man
of ordinary intelligence that it must have the effect of
depreciating the value of all unpatented claims by deter-
ring the more prudent class of capitalists from investing in
them. That the subject is simple enough to be embraced
in one general law is proved by the fact that the laws of
the various districts, although differing in details, are in
substance identical, and are substantially contained in the
existing acts of Congress. "The magnitude of the evil
resulting from the uncertainty of mining titles will
perhaps be appreciated when I say that after a residence
of seventeen years with the best opportunity of ob-
serving, I cannot at this moment recall a single instance
in which the owners of really valuable mining
ground have escaped expensive litigation, except
by paying a heavy blackmail. This defect in the
law, like the one concerning a want of reason-
able time to mark boundaries in making a loca-
tion, can be cured by an amendment of the law itself."
In this instance the committee made the same recom-
mendation made to Congress by the Public Land Com-
mission in 1880, namely, the amending of the present
law so that all future occupation, location or purchase
of mineral lands shall be governed by laws of Congress
to the exclusion of all local customs, rules and regula-
tions and all State and Territorial law.
"The third provision in the law in need of amendment
is the provision in Section 2324 concerning annual assess-
ment work necessary to hold the possessory right to a
claim as against the Government of the United States.
The abuse of the present provision is so persistent, so
flagrant and so well known that it is needless to describe
it. Probably every man in this convention has, at some
time in his own personal experience, been guilty of strain-
ing the present provision of the law upon this subject.
We all recognize the statute concerning annual assess-
ment work as insufficient, however, and most earnestly
urge upon Congress such amendatory legislation in this
regard that while it will provide a liberal system for the
bona fide locator who holds and works his claim in good
faith, will still most effectually and incontinently work
for the undoing of every blackmailer and every dog in
the manger."
The report discussed at length the present Federal
statute concerning hydraulic mining in the Sacramento
and San Joaquin valleys. Concerning the constitution-
ality of the Caminetti Act, the report said :
" Let the question be presented squarely, so that there
can be no evasion in the decision. Is, or is not, the Act
contrary to the provisions of the fifth amendment to the
Constitution of the United States ? Does, or does not,
the Act, directly or indirectly, deprive any person of
property without due process of law ? Is the State de-
prived by the Act of any right guaranteed it in the con-
stitution of the United States to protect the navigability
of its streams ? If the Act is held to be constitutional,
as the miners are satisfied to take their chances under it,
they will have to submit to the jurisdiction of the com-
mission, for otherwise their hydraulic mining, no matter
how little injurious, will be unlawful. They would then
at least have this much security in expending the
moneys necessary to take advantage of its provisions —
that they would run no danger of having the Act de-
clared unconstitutional over their heads after they had
spent their money. If the Act shall be held unconstitu-
tional, then those who have already submitted them-
selves to its jurisdiction would cease expending further
money under it, and can apply for the cancellation of
their surrenders on the ground that they were given
without consideration."
The report of the committee on mineral lands was
read by Chairman Jno. M. Wright, recounting the his-
tory of this well known measure, and giving the experi-
ence of those who were seeking the passage of a bill
through Congress providing for a commission to classify
the lands of the State, so that no more mineral lands
would be absorbed by corporations as agricultural land.
He said that, no matter which way the supporters of the
bill turned, they found some technicality or some objec-
tion that put off its passage until too late. The report
recommended that "the Association should continue its
support of the Mineral Lands bill now before Congress,
and to this end a strong mineral lands committee
should be appointed, headed by some gentleman able to
give a large proportion of his time to the accomplishment
of the Association's purposes."
The report went into details of the conflict between
"scrippers" and locators. The difficulty of the oil lo-
cator was that it is sometimes several weeks, and even
months, before he can tell whether or not he is on an oil-
producing claim, and in the meantime the scripper can
come in and "select" the land under his scrip, which
entitles him to agricultural land only. If the scrippers
would select unappropriated lands where the presence of
mineral was not apparent, said Mr. Wright, no one would
question his right to a patent, nor would his right to
mineral afterward discovered be questioned. But in
very many instances the scripper has selected land within
the well known limit9 of oil fields, lands known to him to
contain vast quantities of oil; and he has even gone
further and selected land upon which derricks had been
erected and upon which wells were being sunk.
It was the purpose of the committee to prepare a bill
that would protect the oil locator until he had either dis-
covered oil or had demonstrated that there was no oil in
his claim. The bill provides that locators should have
three months after the marking of their claim within
which to begin work for the purpose of completing dis-
covery— the discovery, if made, to date back to the time
of the location, in order to secure a continuous title. It
provides further that so long as work is carried on with
reasonable diligence the locator shall be protected, but
if he fail to prosecute the work diligently, or if he fail
to commence it within. the three months allowed, he
shall forfeit hi9 claim.
Upon assembling on the morning of the second day,
the 20th inst., the president appointed a committee on
resolutions. The chairman of the committee on mines
and mining reported that material progress had been
made. In the current press is greater and more favor-
able mention. The last meeting of the International
Mining Congress at Milwaukee, Wis., in June, 1900,
unanimously endorsed and recommended the passage of
a law by Congress creating a department of mines and
mining. A bill providing for the creating of a cabinet
office as 90 designed was favorably reported on by the
House committee on mines and mining at the last session
of Congress. When the extent of territory affected, the
diverse interests, and the natural public inertia is taken
into consideration, the committee felt encouraged in the
evidence of progress, and expressed its belief that the
measure, by reason of its manifest justice, will receive
the favorable consideration by our national legislators to
which its importance entitles it. The committee recom-
mended that every member further the movement by
personally addressing his Senators and Congressmen,
and suggested to miners everywhere that if similar con-
certed action be taken by them that such united request
would greatly hasten the ultimate fulfilling of the effort.
The committee did not deem it needful to recount or
repeat the reasons making necessary the creation of such
a department, nor requisite that further argument
should be adduced in support. Such reasons and argu-
ment have been presented and their truth and justice
have been acceded to by thousands of mining men all
over the country, who know that such legislation as that
asked for is a present necessity.
Chairman Thos. J. Barbour, of the committee on
dredging and jetties, presented a detailed report of the
operation of gold dredgers in California, giving consider-
able information of a commercial and technical nature.
The report stated that at the present time twenty
dredgers are operating in California, producing in the
neighborhood of $1,000,000 per year, and no doubt the
coming year will show a large advance in the production.
An invitation from the Union Iron Works to visit that
establishment and placing a tug at the disposal of the
delegates was accepted.
L. C. Crane, pre9t. Petroleum Miners' Association, ad-
dressed the convention and said:
" Our industry is a large integral part of the mining in-
dustry. The value of the petroleum industry to the
State of California cannot be estimated by any one living
man. Petroleum is the basis of our coming industries.
As an experiment, recently in England, a steamer was
propelled 10,000 miles with petroleum. Petroleum costs
more in England than coal, but it costs 70% less to han-
dle it. California faces a new era and that new era de-
pends upon the miner. It will not be very many years
before the smokestacks of our industries will rear their
heads all along the Pacific coast.
" When petroleum was discovered here a few years ago
there were many Californians who doubted the utility of
the crude oil, but now they are all alive to the situation.
"Fully $34,000,000 has been invested in lands, machin-
ery and all that goes to make up the outfit for the pro-
duction of oil. That capital has come largely from the
East. The California oil industry represents to-day a
capital of $116,000,000. We have inquiries from all over
Europe. There are 2000 oil companies in California. The
capital is bound to flow in. We want the co-operation
of our gold miners. We are one brotherhood — a frater-
nity for the common good of California."
W. L. Watts made a report regarding the oil industry:
The records show that the production of petroleum in
California has increased from about 12,000 barrels in 1876
to nearly 2,500,000 barrels in 1899, and the production
for 1900 will be larger.
When he made his report on petroleum in 1896, there
were about 550 producing wellB, and about 100 prospect
wells had been drilled. At the date at which he closed
his report, August, 1900, there were about 1500 pro-
ducing wells and 470 prospect wells, and there is every
reason to expect that the petroleum industry in Califor-
nia will go on increasing in extent and importance.
L. E. Aubrey discussed freight rates. Under existing
circumstances, ore is charged for under a rate schedule
dated September 15, 1899, at the rate of $100 per ton, a
rebate to be made on the showing by the report of the
smelting works that it was lower than the $100 rate
called for, an exemplification of the theory of "all the
traffic will bear." Under the schedule, a man might
ship ore he valued at $50 a ton on a supposed rate of $5
a ton, but when the assay at the smelter showed a value
of $75 a ton he would find he had to pay $2.50 per ton
more. There would be some reason if the rate was made
contingent upon the valuation of the ore by the owner,
for then in case of loss the shipper could only regain the
value he had placed upon it. There is a theory that a
shipper can recover full value regardless of what his first
valuation might be, but there had never been known a
case where a man might recover more than the valua-

tion he placed upon his own shipment even if he recov-
ered that.
A resolution asking that the fixing of the rates on ore
be brought to the attention of the Interstate Commerce
Commission was referred to the committee on resolu-
tion, as were other resolutions proffered.
Chairman Caminetti of the committee on dams and
debris, road the report, which went into the subject at
great length. He discussed tho preliminary barrier
plan of the California Debris Commission illustrated and
described in the issue of June 23, 1900.
The River and Harbor Act of 1900 contained authority
to proceed at once with the construction of the works,
thus giving Congressional sanction to the scheme.
The commission went to work at once with all pre-
liminaries, and has continued energetically to press them
to an early conclusion in order to proceed with the actual
construction of restraining barriers and sottling basins.
Owners of land covered by the proposed site have been
brought together and all rights and lands required, with
| a few exceptions, have been secured. The commission is
now in a fair way of obtaining about 3400 acres for site
purposes within the limits of the appropriation.
The estimates of the commission fix the aggregate of
cost of the completed works at $800,000, $500,000 of which
has been appropriated in equal amounts by the Federal
and our State governments. Plans for the works havo
been prepared by that commission, submitted to and
approved by the Secretary of War, and now in turn
transferred to the jurisdiction of the State in order to
secure approval thereof, so that the appropriation made
in that behalf by California may become available.
In order to fully provide for the completion of the
system contemplated it will be necessary to secure an
additional appropriation of $300,000, one-half from the
National Government and tho other from the State. The
report recommends that the Association use its utmost
endeavors toward securing the quota required from the
State of California at the ensuing session of the Legisla-
ture, and that a special committee be appointed by the
president to wait upon the Legislature and present the
wishes of the Association in that respect, and report
further recommends that the Association also request
favorable action by Congress, and that Senators and
Representatives in Congress be requested to use all hon-
orable means to secure the appropriation of the sum of
$150,000 for this purpose.
The report and supplemental remarks by Chairman
Caminetti elicited considerable vigorous discussion of the
whole subject from the standpoint of the miner, in which
was outlined a plan to further test the constitutionality
of the Act and to curb the course of the Anti-Debris As-
sociation.
O. S. Breese of Los Angeles read a paper on "Mining
in Southern California."
When the convention reassembled on the third day,
the 21st, the first business was the report of the commit-
tee on resolutions; but the committee not being in imme-
diate readiness, President Ralston took occasion to refer
briefly to the action of the anti-debris meeting at Sacra-
mento the day previous as corroborative of his assertions
concerning that matter in his address wherein he charged
that Association with evasion and want of faith.
At the opening of the afternoon session E. C. Voorheis,
chairman of the committee on resolutions, made the
following report :
Whereas, The California Miners' Association was
organized, primarily, for the purpose of devising a
method whereby the great industry of hydraulic mining
could be resumed without injury to the agricultural and
other interests ; and
Whereas, Since that time the mining interest has
broadened by the development of the copper and petro-
leum mining industries to such an extent that it covers
practically the whole State ; and
Whereas, We recognize in the Petroleum Miners' As-
sociation an ally of great importance in the development
of the mineral resources of the State ; therefore, be it
Resolved, That we welcome into the fullest fellowship
our fellow miners who are doing so much to develop the
petroleum mining industry of the State, and pledge to
them our heartiest co-operation and support in every
measure in which we may be of service to them.
Resolved, That we highly appreciate the efforts made
by the National Congress and the Legislature of the State
to secure the passage by each of those bodies of that
measure known as the California Mineral Lands bill;
that we urgently urge upon the Congress of the United
States that such efforts may be continued at its coming
session, to the end that the California Mineral Lands bill
may become the law of the land, and be the means of
preventing further absorption by corporate interests of
of land of great value to the prospector and the miner.
Whereas, Opposition to the efforts of certain of our
fellow miners to operate their hydraulic mines under the
Caminetti law has been made in the courts of the State,
and more suits of a further character are threatened ;
and
Whereas, Where the injunctions obtained in the cases
already brought were^ under a ruling by the court that
the licenses in these particular cases were not regularly
issued, the constitutionality of the law has been chal-
lenged ; now, therefore, be it
Resolved, That the executive committee of the Cali-
fornia Miners' Association shall determine the constitu-
tionality of said law in the courts of last resort by defend-
ing a test case brought against a miner holding a reglu-
larly issued license by the California Debris Commission.
Resolved, That we heartily favor the amondment of
Sections 2319, 2320 and 2324 of the Revised Statutes of
the United States, concerning the location of mining
claims, so that the locator shall be accorded a reasonable
time within whioh to finally mark his surface boundaries
on the ground, so that all local rules, regulations and
customs of miners and all State and Territorial laws on
the location of mining claims shall be abolished, and so
that, while liberal provision shall be made for the pro-
tection of the locator who holds and works his claim in
good faith, the law concerning annual assessment shall
most effectually check the present injurious practice of
holding mining claims year after year without develop-
ment.
Resolved, That in the problem of remedying the crimi-
nal abuses of the land and mining laws of the nation by
E. C. Voorhies, President California State Miners' Association.
the wholesale attempts to secure as agricultural lands, by
the use of so-called scrip and otherwise, great tracts of
the public domain that are unquestionably mineral in
character, and which are recognized as mineral by the
the people who seek to secure them as such by subter-
fuge, legal technicalities and outright perjury, the petro-
leum industry faces the matter of most serious present
concern to it in its relation to the Federal laws and their
administration. We believe that this problem is pecu-
liarly one in which the whole mining industry of the
State is interested, together with the petroleum miners,
and we solemnly pledge our highest endeavors to protect
the heritage of the miner in the public domain in accord-
ance with the letter and spirit of the beneficent laws
which were intended by Congress to sacredly preserve
the vast mineral resources of the public domain to the
mining industry, that their development might be en-
couraged and fostered. We distinctly favor the propo-
sition that where a contest takes place between a scrip-
per and a miner in any department of the United States
Land Office the burden of proof shall be placed upon the
scripper and not on the miner.
Resolved, That one of the most important and feasible
remedies for the said abuses of the rights of the oil
miner on the public domain would be found in the law
unsuccessfully proposed to Congress during its last ses-
sion, by which the location of petroleum placer claims
was sought to be so regulated as to secure to the miner
an opportunity to make technical "discovery " of- min-
eral substances as a precedent to location, in accordance
with law. A measure of this nature is demanded by the
peculiar conditions of the petroleum industry; would be
but a measure of simple justice necessary to give effect
to the spirit and intent of the mining law; would be but
a wise adaptation to the oil industry of the tunnel-site
law, and would work no injury or inconvenience to any
legitimate interest. And that we heartily recommend
the passage of the proposed Act of Congress recom-
mended by the executive committee of the California
Miners' Association, and by the Petroleum Miners' Co-
operative Association, being Senate bill 3326, now pend-
ing before Congress, and earnestly urge our Senators
and Representatives in Congress to use all honorable
means to secure the passage thereof.
Resolved, That in the opinion of this body the
geological conditions attending oil mining and the multi-
plication of wells which penetrate water-yielding strata
and release their stores of water, make wise and timely
investigation of the alleged injuries done to the oil
wells and oil fields by the flooding of porous oil-yielding
strata from such induced flows of water. We note the
fact that the laws of certain Eastern States recognize the
injury to oil interests caused in this way and require the
casing of water-yielding wells in oil regions and the effec-
tive plugging of abandoned wells.
Resolved, That, we heartily favor State legislation
relative to the needs of the petroleum industry, and it is
suggested that one important matter is that of the regu-
lation of mining rights on lands controlled by the State,
including tide lands, the bed of the ocean to the 3- mile
limit, and the beds of the streams, all mining operations
in such ground being now conducted by the simple suf-
ferance of the State and the only mining rights obtain-
able being those based on possession.
Resolved, That in the judgment of this Association
the mining industry of this country, with its output of
raw material exceeding a billion dollars in annual value,
its tremendous significance to the industrial prosperity
of the Nation and its still more splendid promise for the
future, warrants and demands the governmental protec-
tion and assistance that can be adequately extended only
through a Cabinet department of the executive branch
of the Government. We therefore heartily endorse the
now national demand for a Cabinet department of
mines and mining, and invite other organizations to join
with this Association in the effort to secure the creation
of such a department.
Resolved, We deem it the duty of this convention to
place itself on record in favor of liberal encouragement
and protection to all legitimate mining interests and
pledge ourselves to assist in every reasonable manner
any and all legislation, State or national, which is calcu-
lated to remedy existing wrongs. We recognize the
gross injustice of permitting that class of land pirates,
which by Claiming land to be suited for agricultural pur-
poses that is manifestly and essentially unfit for any uses
except mining, to attempt to wrest from purchasers of
State lands their recognized equitable rights, and
through perjury and distorted interpretation of the land
laws of the State, to place serious obstacles in the way of
large investments of money and important oil develop-
ments.
Resolved, We look forward with pardonable pride
,to the early construction, already assured, of the re-
straining barriers for which $500,000 have been appro-
priated by our State and National Governments. We
heartily approve the plans and recommendations of the
California Debris Commission for the construction of
such restraining barriers, as outlined in their official re-
port of 1890 to the Secretary of War, and we hereby in-
struct our committee upon legislation to use all honorable
means to secure such added legislation and appropriation
as may be necessary on the part of the State and Na-
tional Governments to carry such work to a final and
successful completion.
Whereas, The great mineral wealth of the State is
increasing from year to year, and greater! demands -are
made upon the State Mining Bureau; therefore be it
Resolved, That we recognize the fact that the future
development of the State depends in a large measure
upon the future development of its water resources and
the preservation of its forests; therefore, we favor the
immediate and thorough investigation of, and report on
our water resources and the best methods of improving
and developing the same; the collaboration of the Fed-
eral and State Governments in such investigations; and
the proper appropriations therefor by our State Legisla-
ture. We desire, and urge upon the Federal Govern-
ment, that all public forests be reserved from sale, and
the establishment of a forest patrol, and we favor the en-
actment by the State Legislature of such penal laws as
will lessen the danger from forest fires.
Resolved, That this Association again express its deep
satisfaction at the justice of the policy and action of the
Commissioner of the General Land Office, Binger Her-
mann, in his suspension from agricultural entry of a
large area of probable oil lands in this State pending an
impartial investigation of their mineral or non-mineral
character, thereby preserving to the oil miners the
mining rights which are theirs by both the letter and
the spirit of the laws.
Resolved, That this Association holds itself greatly in-
debted to the public press of San Francisco and the
mining counties for the assistance it has given not only
to the Association, but to the mining industry of Cali-
fornia during the past year.
_ Resolved, That this Association is under deep obliga-
tions to the merchants, manufacturers and business men
of San Francisco for their generous financial aid during
the past and previous years, and recognizes the fact that
without this special assistance it would have been unable
to accomplish one-half of what has been done. The As-
sociation is Ifree to acknowledge this, since the largest
proportion of the funds received has come from these
gentlemen, who are only indirectly interested in the
mining industry.
The report was taken up, seriatim, and adopted section
by section as above.
The committee on revision of the constitution and
by-laws reported as follows :
Your committee on revision of constitution and by-
laws of the California Miners' Association recommend
the following amendments to said constitution and by-
laws : Amend Section 2 of Article 1 of the constitution
to read as follows : Section 2. The objects of this Asso-
ciation shall he to protect, develop and foster the mining
and mineral industries of the State of California in all its
branches.
Amend Section 1 of Article 2 of the constitution to read
as follows :
Section 1. The officers of this organization shall be a
president, two vice-presidents, secretary, assistant secre-
tary and treasurer, and an executive committee consist-
ing of not less than fifteen members selected at large, and
two additional members from each county represented in
the Association, to be selected by the president of this
Association.
Amend Section 2 of Article 3 of the constitution to read
as follows in the last paragraph :
In the absence of the president, one of the vice-presi-
dents shall perform the duties of that office.
Amend Section 6 of Article 3 of the constitution as fol-
lows : Section 6. All checks and drafts of this Asso-
ciation must be drawn by the secretary and signed by the
president and secretary.
Amend Section 2 of Article 4 of the constitution to read
as follows ;
Section 2. It shall be the duty of the executive com-
mittee of this Association to promote the formation of
branch organizations in all counties where mines or min-
erals constitute one of the important industries. Such
organizations shall be recognized as branches of this As-
sociation.
Amend Section 4 of Article 4 of the constitution by
eliminating the clause : " All individual members of the
Association in counties abutting on San Francisco bay,
$5 per annum."
All other sections of the constitution and all sections of
the by-laws to remain unchanged.
The report was adopted as read.
Col. W. H. H. Heuer, U. S. Corps of Engineers, and
senior member of theCal. Debris Commission, in response
to invitation, took the platform and said:
"The question most frequently on the lips of the
miners is, ' Where is that $500,000 appropriated for the
dams ? ' I'll tell you. There has not been one cent
drawn from it. The State has spent nothing for the
preliminary work. You'll get your dams and they'll im-
pound debris; and while I don't say they will allow the
resumption of hydraulic mining, I do believe that they
will prove so effective that in time you can turn your
mines loose. ' '
The election of officers for the ensuing year was next
in order. E. C. Voorhies of Amador county was unani-
mously elected president, Fred Zeitler of Nevada county
and Lew E. Aubrey of Los Angeles county were, by ac-
clamation, elected first and second vice-presidents, re-
spectively, and, in an equally unanimous way, E. H.
Benjamin of Alameda county was re-elected secretary
and Sam'l J. Hendy of San Francisco was re-elected
treasurer. As all the officers are serving without salary
or emolument of any kind, and as the position of secre-
taryship involves considerable expense, a motion unani-
mously prevailed that the Executive Committee of the
Association hereafter provide " a liberal salary " for the
secretary.
After the customary votes of thanks, the convention
adjourned sine die.

November 24, 1900.
Taviche, Ocoilan District, Oaxaca, Mexico.
Written tor the Mining and Scientific Press.
Mexico is a land of mystery and romance, with
creeds and civilizations more ancient, with ruins
more wonderful, with manners and customs more
strange, with soil and climate more rich and varied,
than any portion of these United States, and yet
there is less known about our next door neighbor
than of foreign lands we must cross the broad Atlan-
tic to see. This is true of the vast majority of
people. Tourists and sight-seers will traverse half
the globe in search of something new or strange in
the old world, while sights more wonderful lie right
at their door and can be reached in a Pullman car.
fails to fascinate the student of history and fill the
mind of the casual observer with wonder.
Mexico is a rich mineral country, and has yielded
nearly two-thirds of the silver that forms the stock
of the white metal of the world.
For years a syndicate has held a concession on a
tract of rich mineral land 35 miles square in the dis-
trict of Taviche, Ocotlan, Oaxaca, and not having
complied with the requirements of the concession the
Government took possession and threw the same
open to the world for denouncement — that is, for set-
tlement, as was Oklahoma, or the Colville reserva-
tion last month. No rush was made, as was the case
at Oklahoma or Washington ; but few went in.
Some of the properties are reported valuable. Of
the Benjamine, owned and operated by the Teressa
owned and operated by a company of which A. Fous
is manager, are yielding handsome returns.
The camp is well situated. To-day it is 35 miles
from a railroad, but by January, 1901, the extension
of the Mexican Southern Railroad to Ocotlan will
bring it within 12 miles of railroad facilities. From
Ocotlan the main road will be extended to Ejutla.
The Los Paras mines, owned and operated by Senor
Garcia, lie west of the Taviche camp about 30 miles.
This is one of the famous mines of Oaxaca. Some
illustrations are given herewith of this region, on this
page and the front page.
There are fourteen veins now opened, connected
by tunnels and incline shafts, over 6 miles in length.
The ore from these mines yields from 2 to 8 ounces
gold per ton.

To the tourist everything is new and strange — the
people, their manners, customs, social life, business
habits, religion and superstitions. In all of these
Mexico differs from every other country in the world.
The first view of the City of Mexico surpasses any
other city on the continent of America. Nestled in a
valley of exceeding beauty, it gleams like a jewel in
its setting of silvery lakes and dark-green hills. The
belfries and towers of its hundred churches and pal-
aces are mirrored against a sky that baffles all de-
scription. It was this sight that inspired the feel-
ings of awe and admiration in the bosom of Cortez as
he stood with his little band of adventurers upon the
crest of one of the surrounding hills and looked down
upon the capital of the Montezumas for the first time.
The sight is truly inspiring, and all tourists are pro-
fuse in their exclamations of its grandeur. Mexico

Co., J. B. Powell of Toronto, Canada, says: "I
found at the bottom of its lowest workings, about 470
feet deep, a body of ore between two walls 14 feet
wide, 16 inches of this vein being a rich hilo. A
choice sample gave an assay of 13,077 ounces silver
and 11| ounces gold per ton. The whole of this hilo
of 16 inches wide would assay 1500 ounces silver and
6 ounces gold per ton. This, of course, was an ex-
traordinary result, but the average sample of this
14-foot vein gave 176 ounces silver and %\ ounces gold
per ton."
The La Squadra adjoins the Benjamine and is
owned and operated by Senor Don Von Baights.
The Zapote mine, owned and operated by Mr. Wal-
lace, has proven a good property. He has taken out
ore ranging from 300 to 800 ounces silver per ton and
the usual pro rata of gold.
The El Conejo, the El Mojura, the San Antonio^
The affairs of this company are conducted on
purely Mexican methods. The ore is carried out of
the mine on the backs of boys. One of the wonders
is that some of these boys are stone blind, but with
unerring instinct they will find the drifts, secure the
ore, carry it out on their backs and deposit it in its
proper place, then return and repeat the process all
day without a mistake. They can pilot one to any
part of the mine he wishes to find. Eight miles from
Taviche is the St. Martine district, where Boss &
Armstrong have a mine, in which at a depth of 50
feet was found ore running 1700 ounces silver per
ton, besides considerable gold.
Some of the old properties have yielded consider-
able amounts to their owners. There are about
twenty-five other mines being worked in the district
mentioned, all of which, , a greater or less extent,
are paying their owners.

Oil Fields of Fresno County, Cal.
Written for the Miking and Scientific Pkess by H. G. Parsons.
Coalinga District. — The oil-bearing territory in
the neighborhood of Coalinga, Fresno county, has
been partially defined for many years. In a mono-
graph written by Prof. W. L. Watts, assistant State
Mineralogist, and published in 1894, the topography
and geology of the entire district were described with
some minuteness. At that time several shallow wells
had been previously sunk, and a few of these wells
were producing limited quantities of petroleum. Re-
cent developments prove that this oil production was
merely a seepage from the oil-bearing strata lying
far beneath the bottom of the deepest of these wells.
In 1898 the attention of C. A. Canfield, who had pre-
viously been instrumental in oil development at Los
Angeles and elsewhere, was centered on the district
9 miles north of Coalinga. The experience of others
at this point had been disappointing, rather than en-
couraging. Hut Mr. Canfield seemed imbued with
the idea that this could be made a productive dis-
trict. Enlisting the financial aid of Mr. Chanslor of
Los Angeles, he proceeded to sink a well. He went
down deeper than any of his predecessors, and on the
third trial he struck a "spouter." This was the
basis of Messrs. Canfield & Chanslor's wealth, as it
was the beginning of the oil excitement and activity
in the San Joaquin valley, which has increased from
that day to this. The gentlemen named continued to
sink wells in close proximity to their successful
venture, and in nearly every case they secured
another producing well. Other companies came in
and they, too, obtained oil in profitable quantities.
The Coalinga district became famed over the entire
country. It is still one of the most productive fields
for its size in the State, and its shipments are undi-
minished.
The S. P. Railroad Co. built a branch line west
from Goshen to Alcalde several years ago. This was
done to reach certain coal measures in the same
range of hills that are now producing oil. The coal
was bituminous in character, and was found upon
practical test to be too soft for profitable use. There
is no doubt that the genesis of this coal is closely
allied to the petroleum deposits which have since
been tapped. The railroad from Huron westward
was fast becoming a piece of unproductive property.
It would probably have been abandoned and the track
pulled up if petroleum had not been discovered at
about the time it was. The railroad has proven a
great boon to the oil industry at Coalinga. It af-
forded an instant market by transporting the oil to
the center of manufacturing industry. The Coalinga
oil, like that which has since been discovered in other
parts of the San Joaquin valley, is a fuel product,
with an asphaltum base. It is decidedly popular as
a substitute for coal in steam production. There is
also a growing demand for this oil from manufac-
turers of illuminating gas. There is almost no waste
when it is used for this purpose.
Soon after oil was discovered in paying quantities
at Oil City, which was the name given to the cluster
of buildings which sprang up around Messrs. Canfield
& Chanslor's wells, the Union Oil Co. of San Francisco
provided tankage facilities in the field and laid a pipe
line 9 miles in length to the railroad track. Their
charge for storing the oil and piping it to the tank
cars is 10 cents per barrel. It is needless to say
that the line has proven a profitable bit of property.
It has probably paid for itself several times over.
The Coalinga Oil Co. (stock in which is largely owned
by Canfield & Chanslor) constructed a 30,000-barrel
tank some distance from the oil field about one year
ago, and connected the tank by a pipe line with their
wells, but they have never yet connected the tank
with the Union Oil Co.'s pipe line, nor have they laid
an independent line to the railroad track. Thus the
only purpose served by the Coalinga Co.'s tank is
that of a reservoir for any surplus oil which could not
be handled by the Union Oil Co. There has been no
occasion to use it for this purpose as yet. At the
time of the writer's visit to Coalinga, however, the
Home Oil Co. had not been shipping for nearly a
month, and the Union Oil Co.'s tanks were nearly full.
Had the Home Co. not made arrangements to ship
soon thereafter, the Coalinga Co.'s tank would have
proven a great utility. The Union Oil Co. has also
laid a pipe line to a new portion of the Coalinga field,
on Section 28, where several wells have recently
added to the production of the district.
The water question is usually a serious question in
the central California oil fields. Artesian water-
often struck in these regions instead of oil — usually
carries in solution so much salt, sulphur or other
minerals as to make it unpalatable for drinking pur-
poses, as well as undesirable for use in boilers for the
generation of steam. At Oil City the water ques-
tion has been met in a tolerably satisfactory manner
by the Coalinga Water Co. This corporation has a
pumping station on the plains, 3 miles from Coalinga
and 6 miles from Oil City. Water is pumped from
two wells, each 300 feet deep, and it is thence forced
into tanks on the top of a high range of hills, 5 miles
distant and 1180 feet above the pumping station.
From here it flows by gravity to the boilers of the oil
companiesiat Oil City and to Section 28. This water
is not the best for domestic purposes, and many fam-
ilies own small stills, with which they procure distilled
water. Stock drink the water freely, and it is used
unchanged in the boilers, where it incrusts the flues
in a short period. Another company has developed
a purer, but more limited, water supply in one of the
canyons west of Oil City.
The Coalinga Oil Co. , largely the property of Can-
field & Chanslor, as before stated, is the largest pro-
ducer in the Coalinga field. This company has at
least a dozen productive wells, one of which is a copi-
ous flower at this date, considerably more than a year
since it was sunk. The Canfield & Chanslor Co. is
closely allied to the Coalinga Co. Each of these com-
panies is now drilling a new well, showing that devel-
opment has not ceased on Section 20, where the
original discovery was made. The pumps at several
wells are run from one jack, centrally located. The
fuel used on Section 20 is gas that is obtained in con-
junction with the oil. As oil is drawn out of the wells,
a considerable amount of gas is liberated. This is con-
ducted by pipe lines to retorts in various parts of
the field, and is thence drawn to the boilers as needed.
Thus the pumping arrangements are almost entirely
automatic. An engineer, to attend to the water sup-
ply in boilers or to overlook the gas engines stationed
here and there, is the only employe needed for this
part of the work. The arrangement is decidedly
economical.
The Home Oil Co., in which Canfield & Chanslor
were once largely interested, but from which they re-
tired by sale of their stock more than a year ago, is
the second largest producer in the Coalinga district.
They have five producing wells, from only one of which
the oil is pumped; the others are flowing wells. One
of these is the famous Blue Goose, or Well No. 3,
which started to flow over a year ago at the rate of
1100 barrels per day. It finally settled down to 200
barrels per day, which is its present production. The
other wells started to flow at the rate of 400 barrels
per day, and they, too, settled down to a much lower
rate of production. The total production of the Home
Oil Co. is said to be about 15,000 barrels per month.
The company is now drilling wells Nos. 6 and 7. They
have just completed a steel tank of 30,000 barrels ca-
pacity.
The Blue Goose Oil Co., which has a well on Sec-
tion 20, not far from its celebrated namesake, is still
drifting and is down over 2000 feet without striking
oil. They are greatly embrrassed with water, as it
comes in almost as fast as it can be pumped out.
They have one of the finest holes in the camp, with
7f -inch casing from top to bottom. Oil is the one
thing needful to make a fine well.
The experience of this company is no more unfortu-
nate than that of several other concerns which began
operations quite close to the Chanslor & Canfield and
the Home gushers. They put down holes to a depth
of 1000 to 2000 feet, but found no oil. Apparently
under part of Section 20, 19-15, there is a pool of
petroleum. If the field extends continuously to the
northwest or west, as was thought at first, this fact
must yet be demonstrated. The field seems certainly
to extend to the southeast, or, at any rate, another
pool exists under Section 28, where the greatest ac-
tivity in development work is now apparent.
The Hanford Oil Co. own all of Section 28, but they
are themselves drilling only one well. They have
three-fourths of the section leased to other compa-
nies. The Independence Oil Co., lessee of the S.W. J
of the N.E. } of Section 28, has three producing wells,
while Well No. 4 is in oil sand. This was struck at
730 feet and is 50 to 60 feet thick. The Twenty-eight
Oil Co., lessee of three-fourths of the N.E. } of Sec-
tion 28 has two finished wells, which will be producing
as soon as a pumping jack can be rigged ; a third
well is being drilled. The oil sand in these wells is
100 feet thick. The Oil City Petroleum Co., lessee of
240 acres on Section 28, has three producing wells,
averaging sixty to seventy barrels per day each.
Well No. 4 is about finished. The oil sand is struck
at 730 feet; well is finished in clay at 900 feet. The
Rock Oil Co., lessee of the W. i of the S.W. } of Sec-
tion 28, is just finishing its first well. It will thus be
seen that Section 28 is proving promising and pro-
ductive territory. These wells are sunk on the sides
of a spur of hills, running southwest from the main
range, and they are nearer the valley than the wells
on Section 28.
The Confidence Oil Co., which owns Section 25,
19-14, where they have a well in the oil sand at 775
feet, are about to insert a pump. The Wisconsin
Oil Co. is drilling on Section 32. The Minnesota Oil
Co., on Section 33, spoiled their first hole, and they
are now drilling a second hole, with good indications
of oil. This is still nearer the foothills than Section
28. The Investment Oil Co., on Section 16, 19-15, is
now down 1900 feet, but have found no oil sand as
yet.
Considerable activity is expected in the newer
part of the Coalinga district, on Sections 28, 33, etc.,
the coming winter.
Grbgoe Blanck, a Hungarian, has invented a
loud-speaking telephone, and by the aid of a power-
ful inductive coil has succeeded in telephoning over a
distance of 1000 miles. The crux of the invention is
that, by means of the coil, articulation of the speaker
is intensified as the words pass along the wire. Be-
sides connecting the instrument with the telephone,
the inventor will attach it to the electrophone, and
by this means one will be able to sit in a room and
listen to what is happening in a theater without hav-
ing to insert the tubes into the ear, as is now neces-
sary. The sounds would proceed from the electro-
phone in much the same manner as they are recited
by the phonograph.
Experimental Burning of Oil.
To tiie Editor : — Following is an account and some
figures in regard to an attempt to burn oil, which
may be of interest to anyone interested in obtaining
cheap fuel — for, although our effort failed, we often
learn as much through our mistakes and failures as
we do through our successes. We are located in a
place where wood costs $5 per cord, and, wishing to
reduce the expense of working an old dump, which
involves but the question of cheap fuel to make it
profitable, we concluded to try burning oil.
Our attempt to burn oil proved more expensive
than burning wood, oil being laid down at the mill at
a total expense of $3 per barrel. We burned 1J cords
of wood per twenty-four hours, and calculations based
on information collected before attempting to burn
oil led to the belief that oil was cheaper. We are all
green in regard to burning oil, and perhaps the con-
ditions under which we burned it are not calculated
to give the best results. We installed the oil battery
under the direction of a man from Los Angeles,
which consists of an oil tank 6 feet in diameter by
30 inches high, from which runs a pipe conveying
the oil through a heater, heated by exhaust steam,
to the burner. The oil burned well with steady flame
and no smoke when using a certain amount of oil, and
a certain amount of steam to blow with ; but, if more
steam was used, it would burn unsteadily, with occa-
sional small explosions, something like a sudden back
draft. The arrangement of the furnace is like the
enclosed sketch :
Mmws MoSacNTificPiicss
7Wiw\
We managed to keep steam between seventy and
eighty pounds, but found it no easy matter to do so
without constant attention to the burner, and the
consumption of oil was such as to make it much more
expensive than wood. Notwithstanding our failure
to economically burn oil, we are in hopes to reduce
the amount of oil consumed, and would be glad to
hear of any improvements that we could make to re-
duce the consumption of oil.
Following are the figures, conditions, etc., noted
during a run of 11J hours. We used three different
burners during the run and measured the oil every
hour as it lowered in the tank :
First burner — Run, 5 hours; burned, 1\ inches oil.
Second burner — Run, 5 hours 45 minutes ; burned,
2} inches oil. Third burner — Run, 1 hour; burned,
» inch oil. Total run, 11$ hours; total burned,
5 J inches oil.
5i inches = 20,866.50 cubic inches in 111 hours.
At 231 cubic inches to gallon, makes 90.32 gallons.
Oil per hour for four stamps, 7.686 gallons.
Oil per hour for one stamp, 1.921 gallons.
Boiler, 30 inches by 8 feet.
Engine cylinder, 5" x 8".
Four stamps, 850 pounds.
Speed of engine, 350 revolutions per minute.
Number of drops per. minute, 100; 5-inch drop.
Feed water for boiler, injector.
Flame shot direct ; no larger.
We would be glad to learn if conditions could be in
any way improved. H. T. Sedglet.

How Fires Are Started.
The Railway Review has collected some curious
examples of the way in which fires may be caused.
In one instance, where some waste, which had been
used with mineral oil, had been thrown into a safe
place, an insect crawled through it, and then, carry-
ing some pieces of the oily fiber sticking to his body,
made his way to a gas jet. The cotton fibers which
adhered to him caught fire, and he dropped, blazing,
to the floor, setting the building on fire. In another
case a quantity of waste was supposed to have been ■
ignited by an electric spark which passed from a
belt running close to it to some conducting substance
through the cotton, which it ignited on its way, as
sparks of frictional electricity can very easily do. In
two cases destructive fires are said to have been
caused by water. In one of these a flood caused the
water to rise high enough in a factory to reach a pile
of iron filings. The filings, on contact with the
water, oxidized so rapidly that they became intensely
heated, and then set fire to the neighboring wood-
work, and the building was destroyed. In the other
case the water from the engines, during a fire, found
its way into a shed containing quicklime, and the
heat generated by the slacking of the lime set fire, to
the shed, and this to other buildings.

Oil and Gas Yielding Formations of
California.
W. L. Watts has completed his bulletin on the
above subject, and in a short time it will be issued by
the California State Printing Office under the
auspices of the Mining Bureau. The scientific stand-
ing of Mr. Watts gives value to his views from an
impartial and expert standpoint. Through his cour-
tesy we are enabled to publish some of the salient
points, that the information contained therein may
have wide and immediate circulation among those
most interested.
In the bulletin he will cite the geological formations
in the San Joaquin valley, in the course of his obser-
vations saying that " the Neocene formations on the
eastern side of the valley are much less dis-
turbed than those on the western side. On the
eastern side they are usually inclined at a very
slight angle, generally less than 15°, while on the
western side the inclination is seldom less than 20°,
and sometimes as high as 70°. The reason of this is
that the earth movement which so greatly disturbed
»the rocks of the coast ranges at the close of the Neo-
cene period affected but slightly the Neocene forma-
tions in the foothills of the Sierras. The development
of the remunerative oil field at Kern river, on the
eastern side of the San Joaquin valley, where the
formations are so slightly disturbed, warrants the
assumption that other localities may be found where
oil-yielding rocks which have been subjected to but
very little disturbance form a wide and extensive oil
line. The place to look for such conditions is on the
east side of the San Joaquin valley. A great draw-
back to prospecting in the lowermost foothills of the
San Joaquin valley is alluvium, which to a great ex-
tent covers the Neocene formations. It is also pos-
sible that "comparatively undisturbed Neocene forma-
tions may be found in the foothills of the Sierras to
the south of the Tehachapi pass."
Discussing the Kern river oil field Mr. Watts says:
" The Kern river oil field, as far as it has been de-
veloped, comprises an area of about 12 square miles,
and is situated in T. 28 S., R. 27 and 28 E., and
partly in T. 29 S., R. 28 E., M. D. M. Within this
area in August, 1900, about 130 wells had been
drilled and many others had been commenced. These
wells are drilled in groups and some of the groups
are nearly a mile apart. The depth of these wells
varies from 450 feet to more than 1000 feet. The
formation penetrated is, first, alluvium or drift,
which in few places exceeds 50 feet in thickness;
then a stratum of blue clay from 25 feet to 350 feet
thick; beneath the blue clay is a water sand from 10
feet to 100 feet in thickness; beneath the water sand
the formation consists of alternate strata of clay and
sand. The well records show that most of these
sands contain oil, and that in some instances they
aggregate a thickness of more than 300 feet.
" It is a difficult matter to estimate the thickness
of oil-sand strata in a well which is yielding oil, espe-
cially when the formation is caving; but some of the
operators in the Kern river field state that they have
estimated the thickness of the oil-sand in their wells
by carefully casing off all the strata as they went
down, and that they found the oil-sand to be more
than 300 feet in thickness. It is unlikely that the
oil sands in the Kern river oil field will prove of uni-
form thickness or uniformly saturated with petro-
leum; but the development at this date indicates that
the Kern river oil field is the largest developed oil
field in California.
"The owners of the wells in the Kern river fields
state that their wells will produce from 40 barrels to
more than 100 barrels of oil a day. Owing to lack of
transportation, there has not been a sufficiently con-
tinuous production to warrant a definite statement
by the writer as to the yield of the wells in this field.
The oil is a black oil, and it is said to have a gravity
of from 14° to 17° B. Much running sand accom-
panies the oil. Some companies separate the sand
from the oil by running both into a slump-hole, where
the sand settles; the oil is then pumped from the
surface. Other operators pump the oil and sand
into flumes furnished with riffles, which are from 4 to
8 inches in height. The flumes are from 80 to 300 feet
in length, and the riffles are from 8 to 14 feet apart, ac-
cording to the grade of the flume. In some instances
the oil is of such gravity that it has to be steamed in
the well before it can be pumped. In a general way,
it may be said that there is very little gas in the
Kern river oil field, although, in some instances, it is
claimed that enough gas could be collected to supply
fuel for steam purposes. The gas appears to be
held in solution in the oil and separates from it when
brought to the surface.
"There are very few rock exposures in the Kern
river oil field. These show strata of clay and soft
sandstone. The sandstone is light-colored and
formed principally of granitic material. These rocks
resemble the formations which may be seen resting
on the granite a few miles northeast of the oil field.
" Between the oil field and the granite, the sand-
stone contains fossils which identify the formation as
the Middle Neocene. The best rock exposures seen
in the oil fields are on the bank of Kern river in Sec.
2, T. 29 S., R. 28 E., M. D. M. At this point, strata
of sandstone, somewhat impregnated with petroleum,
dip to the west of north at an angle of less than 10°.
It is difficult to estimate the precise direction of the
dip of the oil sand, even when the depth at which the
oil sand was struck has been given. The reasons of
this difficulty are : First, it is impossible to tell
whether or not the first oil-yielding stratum is the same
stratum ; second, it is evident that the strata vary in
thickness within a short distance ; third, the angle of
the dip is so slight that it is necessary to use the
records of wells which are far apart for the purposes
of calculation ; fourth, there is every reason to be-
lieve that the strata penetrated in the Kern river oil
field undulate.
" Notwithstanding the difficulties referred to, the
writer collated the well records kindly furnished him
by the well owners in this oil field. Prom these
records it appears that in the northern portion of the
field the strike of the oil sand is about N. 30° W., the
dip being S. 60° W. at an angle of less than 10° ; and
in the southern portions of the field the strike is about
N. 70° W., the dip being S. 20° W. at an angle of less
than 10°. It is probable that N. 60° to 70° W. is the
prevailing strike of the Neocene formations in the
Kern River district.
"In August, 1900, when the Kern River district
was visited by the writer, the Kern river might be
said to bound the developed portion of the Kern river
oil field on the south and east. The rock exposures
on the banks of the river show no evidence of any
fault or line of geological disturbance to which the
course of the Kern river might be attributed ; and the
terraced banks of the river indicate a long period of
gradual erosion. There is a reasonable probability,
therefore, that remunerative oil-yielding formations
will be discovered on the south side of Kern river."

The German Meinecke.
To the Editor: — In these days of economical min-
ing, when engineers are searchiug, not for ores run-
ning thousands of dollars or hundreds of dollars to
the ton, but seem to be rather devoting their time
and attention to securing the last ten cents per ton
from a large tonnage, a brief description and plans
of a machine that has been in practical use for many
years is in order, especially as this machine has been
so thoroughly tried that it is no longer a theory but
an actual condition, and is, in fact, a satisfactory,
practicable, easily handled and correct piece of ma-
chinery. The machines in the Smuggler mill were
imported from Germany, and have been in use by me
for many years, and have been in use for a much
longer period than this in the old country. Classi-
fication for size of the sands of any mill, it is gener-
ally conceded, is one of the most important branches
of concentration, and one that requires more study
and care than at first glance would seem that it
would warrant. The importance of separating ore
into sizes, however, before attempting to concentrate,
either on jigs or tables, is so self evident that it
hardly requires any special argument. The mere
fact that a chunk of lead the size of a marble will
not fall more quickly than a chunk of some kind of
rocks as large as a crabapple, but that a piece of
lead as large as a marble will fall more quickly than
a piece of rock the same size, is about the only
argument that this is needed. When rock gets so
fine that it is practically impossible to size it by
means of screens, owing to the fact that the smaller
the hole in a screen the thinner the metal has to be
in which these holes are punched or drilled, makes
it necessary to size this ore in some other way. Of
course we all understand that the hydraulic sizing
cannot be as acceptable as screen sizing, and it is
simply because it is impossible to screen size the ore
that we try to get some other means of accomplish-
ing the same object. This, as a rule, is done hydrau-
lically on the German plan, for making this classifica-
tion. It is easily adjustable, simple, and almost im-
possible to get out of order. It should immediately
precede the spitztkasten or settling box. Of course,
in all hydraulic sizing the great . trouble is that the
factor of weight, as well as size, enters very largely
into the law of bodies falling through an upward cur-
rent of water, and naturally any hydraulic classifier
will, to a certain extent, effect a partial concentra-
tion in itself. A perfect sizer for the finest of
slimes is yet to be invented or discovered. The most
of the classifiers for size are based upon the principle
of dropping the slimes through an upward current
of water and drawing it off by a siphon as this one
does. But the most of them, unfortunately, intro-
duce water from an upward current each time that
any one size is desired to be drawn off. For example,
in drawing off one size, they introduce water at the
bottom under pressure, and they go through the
same process, adding more water in a different re-
ceptacle for getting another size. The objection to
this is two-fold ; first, it is extravagant in the use of
water, and sometimes water is scarce, and secondly,
such a flood of water is introduced into these slimes
as to be a very great detriment. As a matter of fact,
for the successful concentration of slimes, the less
water above that absolutely necessary indroduced
the better. The German meinecke has to a certain
extent obviated this difficult}', by means of a pres-
sure tank of clear water located at from 4 to 10 feet
above it, thus introducing an upward current of wa-
ter, at the pipe flange, and drawing off four different
sizes of sands and meals, so that only one-fourth of
the amount of water ordinarily used is necessary.
Of course this machine could be built with as many
siphons as would be required, but in practical use it
would probably be more advisable to have more of
them in use rather than to make each larger.

Steam and Gas Engines.
A correct answer to the question, What is the com-
parative cost of operating a gas engine and a steam
engine equal of power ? involves a special solution for
each individual problem. Considered solely as a ma-
chine for converting the total energy of the fuel into
mechanical work, the gas engine is far more efficient.
There are gas engines in operation which transform
over 25% of the heat in the fuel into useful work,
while in the best recorded performance of the steam
engine barely 14% of the energy in the coal burned
has been thus accounted for, and in the average
steam plant, not to exceed 5%. There are many
small plants, consisting of common slide engines, with
uneconomical types of boilers, in which less than 2%
of the energy of the coal burned is converted into
mechanical work. At the same time it must be re-
membered that a given number of heat units in the
form of fuel suitable for use in a gas engine costs
more than an equal number in the shape of coal or
other ordinary fuel suitable for burning in a common
boiler furnace. As a general proposition it may be
assumed that in a plant which operates continuously
the item of fuel alone will be somewhat greater for
the gas engine than for an improved type of modern
steam engine, except possibly in the case of an engine
running on producer gas. When the service is of an
intermittent nature, or the power is required only
for a comparatively short time each day, this differ-
ence in favor of the steam engine becomes less, and
may become a balance in favor of the gas engine, for
the reason that in the gas engine plant there are no
stand-by losses, no radiation nor leakage when stand-
ing idle under full steam pressure, and coal being
burned in banking fires and raising steam. With the
gas engine the fuel expense starts and stops with
the engine. But the fuel cost is only one item in the
cost of producing power. One must consider the
value of the additional space and buildings required
for a boiler plant ; the cost of a stack ; depreciation,
repairs and insurance on a boiler plant. The gas
engine has a field of its own which cannot be occu-
pied by the steam engine, and there is no immediate
prospect of the gas engine encroaching on the legiti-
mate field of the steam engine.
Referendum Dollars.
Joseph Lesher, a Victor, Colo., silver mine owner,
has procured a die, laid in a supply of silver bullion,
and has manufactured several silver coins, each con-
taining one ounce of pure silver. He calls his coins
"referendum dollars," because they are referred to
the people for acceptance or rejection. His silver at
the present quotation costs him 65 cents an ounce,
and the expense of coining is 15 cents — 80 cents in
all. He values his dollars at $1.25 and expects to
issue them as such and keep them at par. He prom-
ises to pay $1.25 in United States money on demand
for each referendum dollar. To avoid interference
by the Federal authorities for imitating the lawful
money of the United States, Mr. Lesher makes his
dollars six-sided.

Niagara Falls and the Tonawandas. This is the sec-
ond transmission line built by that company in which
aluminum replaces copper. Aluminum being so much
lighter than copper, the new aluminum cables are
larger in diameter than the copper cables in use on
the original transmission line and will have thirty-
seven strands, while the new copper cables have
nineteen strands. The conductivity of the aluminum
cables, however, will equal that of the copper cables;
while the weight of material on the pole line will be
very much lighter. It is significant that all of the
aluminum transmission lines now in operation are
successful. In this new Niagara line aluminum will
be given a severe test, as the voltage at present is
11,000 and it is soon to be raised to 22,000.
Water Supply and Irrigation Paper No. 40, on
the Austin dam, by Thomas U. Taylor, professor of
civil engineering at the University of Texas, has been
issued. The paper reviews briefly the history of the
events which led up to the construction of the dam,
and gives the specifications and describes the methods
of building, as well as the more important engineer-
ing details. The flow of Colorado river is also dis-
cussed, and data are given of the accumulation of silt
behind the dam. The final destruction by the flood
of April 7, 1900, is described and causes of the failure
are noted. Application for the paper should be made
to members of Congress, by whom 4000 copies of the
5000 printed are distributed, or to the Director,
United States Geological Survey, Washington, D. C.
Thomas A. Edison has perfected a device for
heating compressed air which, he asserts, util-
izes all the store energy of coal and obtains fully
95% of it.

ing confidential relations with the Guggenheims, says
that while there has not yet been an amalgamation
between the Guggenheims and the American Smelt-
ing & Refining Co. such a combination will be per-
fected about the first of the year. This combination,
it is claimed, would be of direct advantage to pro-
ducers. On account of the increased demand for
silver and the restricted production, the united
smelter interests believe that silver would advance
to 75 cents within ninety days, and to $1 within
a year.
The Snoqualmie Falls Power Co. of Seattle, Wash.,
has succeeded in driving an electric motor 153 miles
distant from the generator. All the lines of the com-
pany were connected up to one continuous circuit,
commencing at Snoqualmie Falls, running to Seattle,
back to the Falls, thence to Tacoma and back again
to the Falls. The regular transmission is 153 miles
to Seattle and 44 miles to Tacoma. The tests were
conducted for experimental purposes, to show that
electric transmission of power can be made oOKirner-
cially practicable at such distance.

Pyritic Smelting in the Black Hills.*
NUMBER II.
In Table II analyses of the Mansfield slags are
given for the purpose of comparison. I have figured
the alumina as a base, as we always did in our work
at Deadwood. With the Mansfield slags before me,
and the knowledge that, in iron smelting, slags (cin-
der) are made in which there are not — intentionally,
at least — any iron, I was not discouraged over the
slags. I had before me the work of Percy and Smith
upon silicates, and their methods of experimenting
with crucible charges. As I was restricted to a

" ID
siliceous ore of even composition, barren pyrite and
magnesian limestone, I set myself to work to see
what slags I could make most easily and profitably
of these materials. I mention the method of experi-
menting, as it may, some day, be useful to others.
At this time there were associated with me, at the
Dakota School of Mines, Dr. H. O. Hofman, now of
the Massachusetts Institute of Technology, and Dr.
W. P. Headden, both of whom made valuable sugges-
tions. The actual experimental work, which was
long and tedious, was done under my direction by
Theodor Knutzen, then a laboratory assistant at the
School of Mines, and for years connected with the
smelting works afterwards erected at Deadwood.
My idea was to take certain quantities of ore and
limestone, and of pyrite, raw and roasted, and melt
them together in a crucible, after the manner of
Percy and Smith, until I had determined the most
fusible and desirable charge, as well as the most
profitable, that could be made from these constitu-
ents. We used Hessian crucibles, about 6 inches high,
and an ordinary crucible furnace. The material was
finely ground, and many charges in varying propor-
tions were tried, the endeavor being always to use
as much ore and as little limestone and pyrite as pos-
sible. We added carbonaceous material to the cru-
cible charges, usually in the form of wheat flour, so
as to imitate as nearly as possible the action of a
blast furnace. After some experimental work, it
was found that a charge composed of 40% siliceous
ore, 45% of magnesian limestone and 15% of raw
pyrite gave a clean fluid slag, and a matte button at
the bottom of the crucible carrying practically all
the gold and silver, thus getting the results which,
according to Bloxam, are obtained from the smelting
together of lime, quartz and pyrite at Zalathna,
Hungary. These slags were analyzed and attempts
were made to deduce formulas for them. The only
noticeable feature was that the slags were high in
silica and (though made without the use of copper)
were free from gold and silver, or nearly so.
Dr. Bichard Pearce has shown that pure iron sul-
phide does not dissolve gold, while the experiments
of E. G-. Spilsbury at the Massachusetts Institute of
i Technology, in matting the auriferous sulphides of
North Carolina, showed that gold could not be con-
centrated in an iron matte satisfactorily. I will
refer to this later.
Having done so much with crucibles, the next point
was to do the work in a large way. Six thousand
dollars was subscribed, with which I bought a 36-inch
round water jacket furnace, a blower and engine and
boiler, and seven carloads of West Virginia coke, and
erected an experimental plant, the so-called "baby
smelter."
The charges which had worked best in the crucible
experiments were tried, I confess, with much anx-
iety, for my lead smelting friends, with scarcely an
exception, predicted failure and dire disaster. The
first slags were duplicates of the experimental ones,
and the furnace ran as smoothly as at any subse-
quent run. I made a carload of iron matte, carry-
ing about twelve ounces of gold, sixty ounces of silver
and no copper, took it to Omaha, sold it to the
smelter there, and returned to the Hills with the
argumentum ad hominem, the check in hand.
The work in the crucibles was never much modi-
fied. The slags from the blast furnace, however,
while fairly elean, were uot so notably so as in the
crucible experiments ; and this led me to believe that
a reverberatory furnace would possibly have done
better work, as it would more nearly have imitated
the crucible experiments. It is said that when this
raw smelting was practiced at Freiberg the rever-
beratory was preferred. We found it advisable to
use somewhat more pyrite in our blast furnace work
than had been found necessary in the crucibles.
The "baby" or experimental plant was operated
for several months, when it was decided to build a
larger plant upon the same lines. Our first Ras-
chette furnace was but 84 inches long ; the next ones
were 120 inches, and the last furnaces erected were
144 inches long. Different degrees of bosh and of
width were experimented upon. We found 36 inches
about the best width.
For many months the charge remained siliceous
ore, barren pyrite and limestone. The first charge
was the substitution of Homestake stamp mill con-
centrates for a part of the barren pyrite, and after
several years the barren pyrite was replaced by cop-
per sulphide ores from Butte, Montana. The Home-
stake concentrates gave rise to large quantities of
flue dust, which in time became very annoying. All
attempts at briquetting the concentrates, even with
costly presses, failed. The problem was finally solved
by resmelting the flue dust in large reverberatory
furnaces, and adding the resulting low-grade iron
matte to the ore charge of the blast furnaces.
During our experimental work I made one experi-
ment in briquetting the concentrates that promised
success. I bought a tank of the so-called ' ' sugar
waste " of the sugar refineries. It is a coarse molas-
ses. I mixed up the concentrates with it and water,
as a mason mixes mortar. When it was allowed to
dry it gave good results, but the plant smelled like a
candy factory, and apparently all the flies in South
Dakota came down to investigate. The sugar waste
was not only cheap and did the work, but it also
added carbonaceous fuel to the furnace as well. 1
believe the idea is well worth following out.
Our practice, as at Mansfield, where the ores also
consist of earthy minerals low in iron, gave rise to
"sows" or bodies of metallic iron. At Mansfield
these sows were formerly sold in England at the
price of pig iron. The ores at Mansfield carry no
gold, and these iron sows do not take up the silver.
Had we been smelting only silver or copper ores, we
might have disregarded them, but owing to the gold
in our charge, and the affinity of metallic iron for it,
these sows were our richest product. In time they
came to replace the brick in the furnace hearths and
foundations. They were virtually blocks of solid
metallic iron, weighing from twenty to forty tons,
and carrying sometimes twenty ounces of gold per
ton. It was extremely difficult, as well as very ex-
pensive, to break them up, but we formerly accom-
plished this by boring holes with a ratchet drill and
repeatedly " shooting " them with dynamite, as many
as fifty shots being sometimes required to break open
the larger masses.
This was repeated until pieces of 100 or 200 pounds
weight were thus obtained. Sampling them was out
of the question, but I made arrangements to have
them smelted by the Omaha & Grant Co., which
treated them with a lead sulphide carrying no gold.
As our sows carry little or no silver, the bullion
obtained by this process was kept separate, and
sampled alone, to the satisfaction of all concerned.
One day I found an account of the method formerly
employed by the Detroit Copper Co. in treating large
masses of native copper, which was to place them
upon the hearth of a reverberatory furnace and
smelt them down with pyrites. I set about arrang-
ing one of our reverberatories with a removable top
and large traveling crane, intending to do the same
with my iron sows, when the foreman suggested the
passing of them beneath the roof of the furnaces at
such times as it became necessary to rebuild the
flues, which would save altering the roof. The first
time a flue came down we placed forty tons of "sow "
or metallic iron upon the hearth, charged the fur-
nace with raw pyrites and copper ores, and fired the
furnace. At the end of three days there was no sow
in the furnace, nor was the hearth' in the least in-
jured, and several hundred ounces of gold had been
recovered at mere nominal cost.
(to be continued.)
The telephone has new uses every day; and, with
each addition to its field, the simplicity makes people
wonder why it was not tried before and what the
limit of its use really is. One of the latest applica-
tions is a device which enables the conductor of a
trolley car to talk to the officers of the company, and
is applied on the St. Louis, St. Charles & Western
Railroad in Missouri. In each car is placed a tele-
phone box of the usual type, containing receiver and
transmitter, but without the regular bottom box for
the battery. In place of this the ground wire, which
is concealed, is connected with the ground wire of
the propelling motor; and the other wires, which are
also hidden, are led through the car into the vestibule,
where they are socketed to connect with the plugs
on the device for making contact with overhead wires
on the poles.
Mining Conditions in Rhodesia, S. A.
To the Editor: — Rhodesia, a country of many
promises and few fulfilments. Such, up to the pres-
ent, must be the verdict. It is also the land of "ex-
cuses." If one is rash enough to ask why the gold
output of the country does not come up to expecta-
tions, two reasons are always given : the rebellion
and the rinderpest. Both are now some years old,
and still the output is but little over 6500 ounces per
month, and is practically stationary, one mine pro-
ducing very nearly half of that. The want of native
labor is also one of the reasons given, but, in many
people's opinions, a very poor one. The native labor
in the country is without doubt poor and ignorant,
but since the shut-down of the Johannesburg mines
that labor, which was on the whole fairly well
trained, ought to have been available. The great
drawback to the country hasn't been so much the
"native" labor as it has the very poor " white "
labor that is and has been in the country. Every
white man who could talk the language, Kitchen Kaf-
fir, and who could "boss" boys immediately after he
had sunk a few regulation 30-foot holes, considered
himself a miner, and, unfortunately for most of the
companies, their highly-paid managers and manag-
ing directors knew no different, and so long as they
were not required to go out into the country and
look after the work they didn't bother how the
"miner " got on.
Their salaries went on just the same, and so long
as the "footage" was satisfactory and specimens
came in, to be sent on to London, everything was
allowed to go on just as it liked.
The country being nothing but a "fissure" coun-
try, in contradistinction to the Rand, which is a
"bedded" country, has to be worked with as much
care and attention as any other " fissure " country.
The average of the gold contents of the veins does
not, as first heralded to the world, run up into
ounces. One can more nearly count the average in
pennyweights on the fingers of one's two hands, and
when one gets down to those sort of figures one has
to have a careful and thoroughly capable manager
to make both ends meet.
The thoroughly capable mine manager in Rhodesia
is almost like the needle in the bundle of hay. Perhaps
one reason for his absence is that the Rand offers
better inducements, not only in salary, but also in
salubrity of climate and the pleasures of life. Rho-
desia has a bad name for fever, which to a certain
extent is unjust. In the pioneer days no doubt fever
had many victims, but since people have begun to
live more rationally its victims have greatly de-
creased in numbers, and, although it may never dis-
appear in toto, as civilization increases so fever will
decrease.
One of the great drawbacks to the mining future
of the country is that large blocks of claims are held
by " developing companies," who expect to pay their
shareholders dividends on "prospect" holes they
float off on the gullible English public. They don't
float off a mine. If they did, that would be all right ;
but most of them sink a few shafts, seldom over 100
feet deep, and do a few feet of drifting, and, of course,
always on the best part of the vein, and then go in
for " flotation. " Snares are taken in part payment
and then "boomed," and after a year's precarious
existence the "flotation company" has to be recon-
structed. And so the wheel goes round. Out of the
enormous number of claims pegged in Rhodesia there
certainly will be a few that will eventually turn out
good, and if such companies as (shall we say?) the
Exploration Co. of London or the De Beers of Kim-
berley would come in and turn some of these numer-
ous prospects into mines, then the future of gold min-
ing in Rhodesia would be assured. But until then
the probabilities are that failure and disappointment
will be the lot of most of the existing companies ; and
their failure will be principally due to themselves for
not having got the proper men to look after their
interests. Of the enormous sums of money that have
been spent in Rhodesia, had only one-half of it been
spent under capable and honest management, the
gold future of the country would not be as bad as it
is now, an unknown quantity. The country would
either have a future before it or else it would be
given up as a mining country and have to depend for
its future on agriculture and stock raising.
Of the success of the two latter industries in the
country there cannot be the slightest doubt, but with
the same proviso as in the mining industry — capable
and honest men, and not younger sons and ne'er-do-
wells, sent out to make their fortunes, generally with
the old Scotchman's advice to his son, Sandy, make
money — honestly if you can ; but make money. '

CALIFORNIA.
Secretary Benjamin of the California
State Miners' Association reports that
since the last annual convention there
have been six meetings of the executive
committee of the Association — the first, on
Jan. 26, 1900, called by President Ralston
for the purpose of obtaining a consensus
of opinion and to decide upon a course to
be pursued in regard to the mineral lands
bill; to discuss the question of the preser-
vation of forests and the conservation of
water, and to take action toward urging
the establishment of a department of mines
and mining in the national Government.
The second meeting, Feb. 20, 1900, was
called to consider a letter received from
Congressman De Vries, in reference to the
elimination of certain lands in the south-
ern part of California from the mineral
lands bill; to endorse the bill prepared by
the mineral lands committee in reference
to oil locations, and to discuss the matter
of scrip location in Shasta county. The
third meeting, on March 17, 1900, was
called, at the request of the committee on
dams, to consider the advisability of send-
ing a representative to Washington in the
interest of legislation regarding debris
dams. As there were but a few pres-
ent, the matter was laid over until
the fourth meeting, on March 23rd,
when the report of the committee on
debris dams was received and adopted,
and A. Caminetti was authorized to pro-
ceed to Washington in the interest of the
debris, mineral lands and petroleum bills.
At this meeting action was also taken on
Congressman De Vries' letter, and it was
resolvod that the Association refuse its
consent to any amendments to the mineral
lands bill that would eliminate any portion
of the State. The fifth meeting, on Au-
gust 13th, 1900, was called for the purpose
of taking action regarding the suit of Sut-
ter County vs. The Polar Star M. Co., to
receive the report of tho Association's
special attorney in tho Red Dog lawsuit,
also the report of A. Caminotti, who
had been sent to Washington in the inter-
est of the Association, and to set the time
for1 the annual convention. The sixth and
last meeting was held on November 13th,
and was called for tho transaction of gen-
eral business prior to tho convention.
During the year, Secy. Benjamin states,
many now members have joined the As-
sociation, and a great many inquiries have
been received for literature and informa-
tion regarding the Association and its
aims and objects. The remaining volumes
of "California Mines and Minerals," re-
ported at the last convention, have been
distributed among libraries and educa-
tional institutions in many parts of the
world and to the different exchanges, ex-
cepting such copies as were sold. The
edition is now exhausted, but the Associa-
tion owns all the plates and half-tones,
and it has been suggested that a second
edition, with the addition of later sta-
tistics, would find a large sale and prove
remunerative to the Association. The en-
tire cost of that publication was $5858.33,
all of which was raised by private sub-
scription and from the sale of advertising
space. All amounts pledged were col-
lected, except one $50 subscription.
During the year the receipts of the As-
sociation have been $11,215.41, as follows:
Cash on hand last statement, $4,211.33;

June 30, 1900, shows for the ten months a
product of $446,665— a net profit of
$160,000. Reports show development
work accomplished for the ten months as
follows: Drifts on the vein, 2401 feet;
raises, 1103 feet; crosscuts, 152 feet, shaft
sinking, 109 feet. Total, 3765 feet. The
greater part of this work has been done
on the 300, 700 and 800 foot levels. The
ore above the 200-foot level is exhausted.
Over the 300-foot level is in sight about
50,000 tons. Between the 300 and 600 foot
levels a large tonnage, probably 200,000
tons, has been opened up of low-grade ore.
On the 700-foot level two ore bodies have
been opened up which appear to have
their apexes near the 600-foot level. In
both of these the vein appears as in the
upper mine, and there is still more resem-
blance to the productive oi'es of past
years in recent developments on the 800-
foot level, where the vein is stronger and
more oxidized than it has been on any
level below the 300-foot. The company
has a bond on four claims controlling the
apex of the Elephant-Cincinnati-Argen-
tine vein — the strongest vein in the dis-
trict, so far as surface indications are con-
cerned.

it is a hard proposition to work and re-
quires considerable money to operate.
The lessees have to pay $10 per ton to
haul the ore.

M., W. & Power Co. recently made some
additions to its Goldfield plant. They now
operate three 1000 H. P. engines for the
generation of electric power. The plant
also includes a 35 and a 12-drill air com-
pressor. The 35-drill compressor op-
erates to full capacity to supply air for
drills in various mines in the district. The
12-drill compressor will be operated by an
electric motor. There are fifty to sixty
electric hoists operating within the dis-
trict, and, as a general thing, they give
good satisfaction. Their capacities range
from 5 H. P. to 30 H. P., the 15 H. P.
hoist being the size most in use. The deep-
est shaft over which an electric hoist is
now working is 500 feet. In many cases
these hoists are under lease to the mine
operators by the company that furnishes
the power. As an example: a 15 H. P.
electric hoist is leased to a mine lessee at
$55 per month, including power, the les-
see contracting to use it six months.

Creek Ore Sampling Co.'s sampling mill
is nearly completed. Its location is on the
Midland and Short Line tracks, south of
Bull Cliff, and it is called the largest sam-
pler in the district. In the main, its work
will be to sample and crush the ore that
goes to the chlorination mills at Colorado
City. It belongs to the same parties who
control the Colorado-Philadelphia reduc-
tion works.
Altman, Nov. 20.
(Special Correspondence). — The Ana-
conda M. Co. is snipping about 1000 tons

lessees. Recently the company installed a
hoist at a point in the tunnel 1100 feet
from entrance, where a 6haft has been
sunk.
Anaconda, Nov. 15.
(Special Correspondence). — The chlo-
rination mill of the Economic Extraction
Co., which was closed down two weeks

(Special Correspondence). — The Ophelia
tunnel, which has progressed to a point
over 4000 feet from the entrance, is being
pushed with three air drills, the work be-
ing under the management of J. M. Par»-
fet. The work is being done with a com-
pound, 6 H. P. compressor, having 16x16-
inch cylinders. A second compressor,
12x12, has been used to charge a small
tunnel locomotive, which operates by
compressed air, instead of steam. At the
tunnel entrance is also a high-speed engine
which operates a suction blower that
draws air from the breast of the tunnel
through a 10-inch hydraulic steel pipe,
the latter being painted inside and outside
with an asphaltum preparation. Ab has
been noted before, the Ophelia tunnel
starts under the town of Cripple Creek,
cuts through one section of Gold hill,
through the ground of the Anaconda M.
Co. and that of the Mary McKinney, pur-
suing a course toward Bull hill.

drifting has been done. On the 660 level
a 300-foot winze is being sunk, a gasoline
hoist having been installed at the collar of
the winze. At the surface is a gasoline
hoist of larger size; also, a belt-driven
compressor, run by a gasoline engine.

Anaconda, Nov. 1!'.
W. S. Stratton, questioned regarding
the present condition of the Independence
mine, which he sold in London, says: " It
is my opinion that the property has been
worked too hard. The management has
simply made a mistake in what it thought
the property could do. I am satisfied
that the Venture Corporation is absolutely
honest in the handling of the stock com-
pany." The opinion of Cripple Creek
mining men is that tho London company
has neglected to do the necessary develop-
ment work and has drawn too heavily
upon the ore reserves for the purpose of
paying large dividends. J. H. Hammond,
after an examination of the Independence
mine, has cabled to London advising a re-
duction of dividends and extensive de-
velopment. Ho is having assays made and
will make a full report. He is confident
that the mine has a great future.

Ambitious mechanics who desire to
obtain better positions and higher wages
might investigate the free scholarship
offer made in another column by the
American School of Correspondence, Bos-
ton, Mass. Situated in a large city which
is a recognized educational and industrial
center, this well-known correspondence
school has many natural advantages in
teaching the theory of the trades and en-
gineering professions. Without leaving
home or losing time from work, the stu-
dent pursues a thorough course of study
under the directions of able instructors,
who are always ready and willing to as-
sist him. Instruction papers, prepared
especially for teaching by mail, are fur-
nished free. These papers, written in
clear and concise language, as free as pos-
sible from technicalities, are considered
by their authors superior to the ordinary
text books on the subjects of which they
treat. In addition, special information
regarding any difficulties in their studies
is furnished students without extra charge.
It should be the ambition of every man to
advance in his trade or profession. A
mechanic with practical experience, sup-
plemented by theoretical education, can
command a better position than a man
without such an education. The results
of long experience in teaching by mail in-
dicate that this method fully meets the
requirements of men who have but little
time for study.

States. Each folio is designated by the name of the principal town
or of a prominent natural feature within the quadrangle. It con-
tains topographic, geologic, economic and structural maps of the
quadrangle, together with a general description. Copies of each
folio are sold at 25 cents each, except such as contain an unusual
amount of matter, which are priced accordingly. Prepayment is
required. Remittance should be made by money order, payable to
the Director of the United States Geological Survey, or by cur-
rency— the exact amount. Postage stamps, checks and drafts can
not be accepted. The folios which are ready for distribution and
those nearing completion are listed in a circular, which will be re-
vised from time to time as other folios are completed, and circulars
concerning the distribution of topographic maps and other pub-
lications of the Geological Survey may be had on application. Com-
munications should be addressed to The Director, United States
Geological Survey, Washington, D. C, from whom a list of sixty-five
of these folios ready for distribution and twelve more approaching
completion can be had. All this in answer to numerous questions.

about 3600 square miles, the area varying with the
latitude. The maps are engraved on copper and
printed from stone. The cultural features, roads,
railroads, cities, towns, etc., and lettering, are in
black; all water features are -printed in blue; the
hill features are shown by brown contour lines, the
contour interval, depending on the scale of the map.
An Act of Congress prescribes that the maps shall
be disposed of by sale. They are sold at the rate
of 5 cents a sheet.
There is also in preparation a geologic map.
Under the plan adopted for its preparation, the
entire area of the United States is divided into
small quadrangles, bounded by certain meridians
and parallels; these quadrangles, in number sev-
eral thousand, are separately surveyed and mapped.
The unit of survey is also the unit of publication;
the maps and description of each quadrangle are

The ups and downs of mining stocks tend to injure
legitimate mining as a business, as the losses occa-
sioned by stock fluctuations deter those who would
put money into mine development as an investment.
Booms and speculative eras are always followed by
depression in the mining business, which must rely on
merit alone. It is this that makes the present
period so prosperous, as in the absence of speculative
excitement the value of the industry itself is made
manifest to those who view it as a legitimate busi-
ness in which is to be found permanence and profit
for legitimate investment.
Beginning the 1st of next month, the estimated
cost of platting and other office work in connection
with the survey of mineral claims will be computed
as follows: For lode claim, $30; for placer claim, $35;
for millsite, $30; for millsite included in one survey
with a lode claim, $15; for each lode claim within and
included in the survey of a placer claim, $15; for sev-
eral lode locations included in one survey, the first
location named, $30; all other locations included,
each $20; for several placer locations included in one
survey, the first location named, $35; all other loca-
tions included, each $25; for affidavit of $500 ex-
penditure of improvements, after approval of survey,
$5. Should an amended order issue, an additional
deposit will be required.
In his annual summary of the mineral produc-
tion of the United States, Dr. David T. Day, Chief
of the Division of Mining and Mineral Resources of the
United States Geological Survey, gives eloquent
reason for the creation of a governmental depart-
ment of mines and mining, with a cabinet secretary,
in showing that the total value of the minerals pro-
duced during the last calendar year amounted to
$976,008,046, an increase in value of nearly 40%
as compared with the figures for the pre-
ceding year. For the first time since 1889
the value of the metallic production exceeded
that of the non-metallic products, the fig-
ures being $527,218,084, and $448,789,962, respect-
ively. This is a great showing, and war-
rants the demand for the creation of such a de-
partment. To such creation there is no active op-
position, the chief obstacle to the fruition of the idea
being public indifference.
In the tunneling of the Simplon, in Europe, now in
progress for two years, Engineer Brandt in charge
has made notable innovation in such boring. Ordi-
narily the hole has first been driven, ' then further
excavation made, followed by the finishing masonry.
In the Simplon two holes are driven, parallel within
the radius of the excavations, leaving a dividing line,
one hole being excavated about 56 feet in advance of
the other. These holes are built for a single track,
the idea being to break away the dividing wall should
increasing traffic make double track necessary. At
distances of 656 feet transverse connections, provided
with doors, are made between the tunnels through
the dividing well. For ventilation air blasts are
blown into one side of the tunnel, returning through
the other side of the divide, carrying out foul air and
gases. The heated air of the interior is cooled by
showers of cold water brought in from higher on the
mountain under high pressure. In this way air at
120° F. is cooled to 60° F. The same stream furnishes
1000 H. P. for driving the drills, which are rotary.
The tunnel will be 12.4 miles long, and is about half
finished, as elsewhere strikes and other accidents re-
tarding its progress.
Different Methods==and Results.
Different business firms and different localities show
difference in business methods ; more especially is this
the case among manufacturers. Some manufacturers
constantly act as though they feared some one would
find out what they are making, to whom they are
selling it, what they are getting for it. There is a
general air of " Sh — sh " about their establishments.
Others want to tell about what they are making, to
whom they are selling their makes, and how much
they are getting therefor ; what they made this year,
and how much they have on their order books. It is a
difference in methods. The reticent and the open
are alike supposably striving for success. Usually it
is best attained by a knowledge of human nature, and
human nature invariably and inevitably inclines
toward the frank, open-hearted man. So true is
this that even where frankness and candid exposition
of plans and results are not natural, their very sem-
blance aids in success. Many clever business men,
merchants, manufacturers and vendors achieve suc-
cess by the assumption that people are interested in
them ; that they are of sufficient importance, anyhow,
to justify public interest ; that if people are not inter-
ested in them it is the fault of the people, and they
propose to take the public into their confidence and
tell their business to them so that they may be inter-
ested. When such people have an order for a stamp
mill, or air compressor, or smelter, or wire ropeway,
or electrical plant, or a dozen concentrators, or any-
thing else in their line, they straightway tell it to the
public, and thus get thousands of dollars' worth of
advertising free. They get ahead, too, and build
bigger shops and get larger contracts, while the
men who whisper " Sh — sh," and gag with grief if
any one mentions them, keep struggling along in a
small shop in a back street. It is one of the proud-
est prerogatives of an American citizen to conduct
his business as best pleases his sovereign fancy, but to
those who are striving for success there would seem
to be an object-lesson in the fact that the successful
are those who believe that success will follow on the
heels of success; that not only "nothing succeeds
like success," but that nothing succeeds but success,
and that one great secret of commanding success is
to go on the principle that people are interested in
you, that you are of sufficient importance to justify
such interest, and that you propose to create, main-
tain and constantly gratify such interest.
If you get people interested in you, you can always
command a share of their trade. Of course, one may
fold his arms, disdain such common, vulgar notoriety,
and starve in dignified seclusion, but that isn't busi-
ness. It may be lofty and grand, but it isn't busi-
ness, and the man who is constantly dodging into a
dark corner, lest his existence be discovered, while
he may be a paragon of goodness and virtue, is not a
business success. This is a mining and scientific
axiom that does not admit of successful contradiction.
Some encouragement to the miner is vouchsafed in
the statement from Washington, D. O, that Thos.
H. Carter of Montana is to be Secretary of the Inte-
rior to succeed Secretary Bliss. The Interior De-
partment has charge of the mining industry, so far
as the mining industry is afforded any governmental
recognition at all, and Carter is a mining man. It is
not intimated that because of this that miners will or
should receive any favors, but with a miner in the
President's cabinet the miner might be accorded a
fairness born of some personal knowledge of the facts
so often to be passed upon by that department.
In Darkest Russia.
The United States Government appears at present
to be "booming" the mineral development of Sibe-
ria. During the past week three government re-
ports from Washington, D. C. , have been received in
this office, telling how wonderfully rich Siberia is.
Two of these state documents are written by Thos.
Smith, United States consul at Moscow, Russia,
whose imagination seems to have been fired by the
alleged discovery, "200 miles west of the Yenesei
river," of quartz outcroppings carrying gold, milling
$18 per ton. Part of our zealous government agent's
long reports sounds like a promoter's prospectus.
The following excerpt will make the miner smile :
"The quartz appears very lively in all the veins yet
uncovered and exhibits the marks of decomposed sul-
phurets. It is, therefore, highly probable that the
great majority of the free gold exists below the
water level in the form combined with iron sulphide.
It will, of course, after water level is reached, neces-
sitate treatment of chloridation or potassium cya-
nide. Water level in this particular locality must,
however, lie at considerable depth, so that the tenor
of these veins may be thoroughly established by the
use of small mills, of free milling capacity only, before
the refractory portions of the veins are encountered."
In further appeal to his fellow countrymen, Consul
Smith vouchsafes the information that the climate
"in some respects is perfectly enjoyable." True,
" the temperature drops as low as 30° to 40° F., be-
low zero," but then " the fall of snow is very light."
Of course, where " the fall of snow is light, " life to
the American miner in Siberia should be one joyous
round of pleasure, even though for five months in the
year the thermometers register ' ' a temperature of
from 30" to 40° F., below zero."
The Government is sending out considerable of this
kind of stuff. It gives a deserving printer employ-
ment, and furnishes a little fun to the miners who
read it, but does not tend to enhance popular respect
for the value of American consular reports.
In this issue appears in its entirety a paper on
" Stamp Milling of Free Gold Ores," read by Dana
Harmon of Nevada Co. , Cal. , before the Technical So-
ciety of the Pacific Coast, in San Francisco, Cal. It
is notable in three instances : it is written by a man
who has daily done for many years the things he talks
about ; it is the longest and most practical talk of the
kind that has appeared for years on this subject, and
it is from a thoroughly independent standpoint, re-
gardless of whose theories are attacked or whose
ideas are disturbed. In accordance with the policy
of this paper — an open forum where ideas are ad-
mitted and the truth alone survives — the article is
given place just as furnished by its author. It will
probably elicit discussion, as it is not at all orthodox
in its statements, and goes against some tradition and
precedent. If it occasion agitation or thought on the
matter, to the result of progress therein, it will have
served a useful purpose. If there be anything in it
susceptible of successful contradiction, our columns
are equally open thereto. This journal does not edi-
torially endorse the statements made in Mr. Har-
mon's paper, but prints it because of its progressive
and positive discussion of subjects that are constantly
interesting to miners and millmen everywhere.
Great Britain sees her foreign mining machinery
trade transferred to the United States, and is study-
ing the causes of successful American competition.
Such change in commercial conditions has a variety
of causes ; chief among them is the underlying fact
that British manufacturers are crystallized around a
set of standards that to the insular mind is orthodox,
while American manufacturers look to the past only
to select the best and disregard the obsolescent.
With the American there is no limit to progress, and
expense is made secondary to success.
The getting together of the American Smelting &
Refining Co. and the Guggenheims, as previously an-
nounced, is not a sale of the latter to the former, but
a consolidation of those two smelting interests. The
consolidated concern will be a big factor in the metal
markets, buying ores, smelting and refining, and
annually producing 75,000,000 ounces silver, 2,000,-
000 ounces gold, 300,000 tons lead and 100,000,000
pounds copper. The smelters on the Pacific coast
continue independent.

Stamp Hilling of Free Gold Ores.
|A paper road before the the Technical Society of thu
Pacific Coast, Sept. 7, 1900, by Dana Harmon. |
A well threshed field. From quo point of view,
talk is idle — your proverbial millman always catches
all the gold. From another, it may be called assault
and battery on good nature to say even a word more.
But one has only to travel to find all sorts of
methods, much guessing and not enough assaying.
Many and deep are the ruts. Somebody must be
wrong. Every decent body can learn. Discussion
does clarify.
Quite as important is it to catch the gold as to
find the ore. In these low-grade days a fellow should
be a milling man as well as a " mining man," whatever
that well-worn term may mean. Mining has gotten
down on all fours with any other business. To the
capitalist there is no essential difference between a
cotton mill and a quartz mill. The girl at the loom
does not run the loom. No more should the battery
boy decide how to amalgamate his ore. A superin-
tendent should not have to run to and fro hunting for
a "good millman" — he should be able to make one
out of raw material.
I have had to do with many different types of mor-
tars and on varied ores, the stamps running from
700 to 1100 lbs. Furthermore, it has been my good
fortune to use side by side from the same line shaft,
on identical ores, with the same screen, batteries of
three different types of mortar, doing this last for
build a Bat bottom ore bin in order to strengthen the
anchorage and bracing.
The objections that such line shaft is subjected to
dirt and awkward position need not be. Sot tin'
base of the mortar 6 feet above the ground, instead
of 3] or 4 feet, as is customary with contractors
This will give plenty of head room around the shaft
and pulleys. Tight wood boxes encasing the shaft
bearings will keep out dirt. Plank or cement this
mud sill floor. Whitewash every post and wall ; oil
cups on bearings.
In figuring on power the uncertain factor is fric-
tion, and if bearings are to be saddled with dirt and
gum, as in the dark they surely will be, power is
wasted. There is a good bit of the personal equation
in friction.
Mortar Blocks. — If wooden mortar blocks are
used, make them long — 10' feet — set on solid rock-
foundation, with a bedding of 1 inche of clean sand.
Ram with concrete on sides and ends. This concrete
should not be continuous all around the mortar
blocks. There should be open spaces leading to the
bottom of the pit, these spaces to be filled with sand,
dry, or tailings run in. There is no better preserva-
tive to wooden mortar blocks than constant wetting.
These sand pillars ensure thorough saturation of the
wood.
Excavate the pit so that you can also build up a
concrete pier for the battery posts to rest on. Have
anchor bolts in these piers so that you can draw-
bolt the battery posts solid to the concrete. Ordi-

over two years continuously. Certain definite con-
clusions have, therefore, been hammered into my
head, touching mortars and weight of stamps.
As for the other matters of mill practice I would
not have it understood that I have reached any one
given method of treatment applicable to all ores.
I have learned to discard notions that once were
holy as though from the Koran — these notions of an-
cient and honorable lineage, of good report, bearing
the greasy thumb marks of the craft. I have been
taught the secret work of the fraternity, for I have
! carried the dinner pail and have worn cotton in my
l ears, the pass tokens of the lodge. I call these no-
I tions, because none of them went to the root and
| logic of the business. Well, these have had decent
I burial. Let them rest.
There are, however, fundamentals to which I wish
to address myself to-night. I believe that these un-
derlying principles must be followed for all ores fall-
ing within the lines of my caption.
The local variance which must be had for ores of
different localities are mainly those of screen and
water, matters determinable by assaying the tail-
ings.
Machinery. — Without going into the details of mill
construction, it may be well to note some points bear-
ing upon the work to be performed. Millwrights are
seldom millmen.
There are all shapes of mortars and tables. Figs.
1, 2 and 3 sbow my own preferences.
There is such a wide difference in jar between the
850-pound and 1100-pound stamps that for the latter
most substantial construction is essential.
Back Knee Frame. — I prefer the back knee frame
because of its solid bracing to the ore bin, the tap-
pets are in plain sight, the pull of the belt is down-
ward on the cam shaft, it requires less lumber. I
narily the battery post is mortised into the line sill,
the latter being bolted to the mud sills ; but this
method leaves a wide space and allows the post to
spring.
The mortar blocks can be solid, i. e., two blocks
bolted and keyed together, or they can be built up of
2-inch plank nailed and bolted together. The mortar
bolts are usually ljx30 inches. I think they should
be longer, say 42 inches.
Concrete Mortar Blocks. — Within the past few
years concrete mortar blocks are coming into vogue.
The concrete is capped with a single block of granite
or iron, a sheet of lead between the mortar and this
capping. Another plan has been to omit the granite
or iron cap piece and instead make the base of the
mortar wider. Battery posts also set on concrete
piers.
I do not know how well these have withstood the
jar of heavy mills. Nor do I consider that their with-
standing the jar of a 900-pound stamp is any evidence
or proof of the effect an 1100-pound stamp will have
upon them.
It is reasonable to expect greater crushing capac-
ity from such rigid foundations. I should look for
crystallized bolts because of this very rigidity. But
I shall endeavor to show that we can crush as much
as we are able to amalgamate in mortars set on
wooden blocks.
It is urged against the wooden blocK that it will
rot out in eight to twelve years ; that it is well nigh
ruined if the mill stands idle a summer or two.
For myself, I should say it does not matter what
happens to a mortar block upon an idle mine.
It has occurred to me — and I throw it out as a
suggestion only — that a durable composite mortar
block could be constructed, the lower half of con-
crete up to the ground line, the upper half (6 feet) of
wood block on end, this block to be anchor-bolted to
I In' concrete.
This would secure solidity, would escape the ex-
cessive rigidity, and would permit renewal of the
wood work at reasonable expense.
GrniEs. — Use the individual iron guide — guides
without the wood bushing.
The stem will not be worn by rubbing directly
against the cast iron guide with ,'„ of an inch play on
either side. Oil sparingly, say once a fortnight, by
just touching the stem with waste moistened with a
good quality of machine oil.
There are iron guides with wood bushings ; but I
have never seen one worth buying. It would be well
to have the cap-piece of malleable iron and the bed-
piece should be 2 inches thick to avoid breakage.
With the old-fashioned oak guides there is too
much friction, too much wear from burning — in a few
months the shoe won't center on the die.
With the individual iron guide the stems will keep
cool. With the oak guide the stems are always
warm and often hot. Heat means friction.
Screens. — I prefer the tin costirg J cent per ton
crushed. Neither Russia iron, brass wire nor steel
can compete with this. Put strips of ij-inch wide of
ji cheap rubber sheet packing between the tin and
the wood frame and you will at least double the life
of the tin screen. Before using, burn off the tin over
a clear forge fire — just heat to redness, keeping the
screen moving to and fro over the fire— this anneals
and toughens the iron.
The three commercial sizes are : No. 0 = No. 8
needle ; 441 holes to square inch. No. 1 = No. 7
needle ; 324 holes to square inch. No. 2 = No. 4 nee-
dle ; 225 holes to square inch.
No. 3 is too coarse for quartz.
If manufacturers would punch a size between the
No. 0 and No. 1 and also a size a trifle coarser than
No. 2, the range of tin screens would cover nearly all
cases of quartz milling. The screen should have a
selvage finish at both ends.
Liners. — Mortar liners removable at every clean
up. The main back liner instead of being in one
piece should be cut so as to give a lower piece of
same width as the front liner.
Skylights. — Nearly every large mill is dark in
the middle ; none need or should be. Builders de-
pend too much upon side wall windows. One sky-
light in the roof is better than four side wall win-
dows. Fig. 4 shows a cheap skylight set flush with
the shakes which I have used successfully even in
heavy snow countries on half pitch roofs. The glass
was ordinary 21-ounce plain. It won't leak and the
snow slides over it. Whitewash walls and ceiling.
Have a well lighted mill day and night.
Warmth of Building. — The plate and concen-
trator rooms should be built so as to be warm in win-
ter season. Never have a draughty mill, icicles and
plate amalgamation won't gee. A few dollars spent
in tarred paper on the walls will be a wise invest-
ment in cold countries. A generous stove with a
couple of hot air drums, 10 feet long by 30 inches in
diameter, will prove economical of wood and keep a
20-stamp mill building comfortable and fit for amal-
gamation.
The items of light and warmth are not luxuries ;
they are the necessaries of the business.
Tables. — Tables should be heavy and solid. These
flimsy tables made of thin boards and light scantling
got out of whack. Figs. 2 and 3 show a table fast-
ened to the the floor which to my notion has ad-
vantages over the rolling table. Ordinarily, 12 feet
long by 5 feet wide will suffice ; 10 feet of this is
nailed to the floor ; the 30-inch apron is removable to
allow setting in shoes and dies.
The frame of three 4x6 inches by 10 feet dressed
on upper edge and notched down \ inch every 2
feet. The boards \k inches thick, 2 feet wide,
5 feet long, dressed on upper side, edges and
ends. After dressing true, cross plane the board
so that there shall be a fall of TV inch from ends to
center. Each board is butted snug to the one next
above it, and nailed or screwed to the 4x6-inch, the
ends of the boards being flush with the outer edge of
the outside 4x6-inch. The side rail is a plank lixlO
inches nailed against the side of the 4x6-inch and
forming a tight joint against the ends of the boards.
To prevent leaking, bruise the edges of the boards
with a blunt chisel, the blade 2 or 3 inches wide and
\ inch thick. As soon as the table is wet these
bruises swell.
At foot of table a double drain box with sheet iron
flap. While mill is running the pulp flows into box (a),
thence to concentrators through a 2-inch pipe, the end
of the pipe projecting \ inch above the bottom of the
box (a) — thus forming sufficient quicksilver trap.
When brushing up, the flap is lowered and the wash-
ings go over into box (b), whence they overflow
through notches into box (a).
These double drain boxes will, under careful mill-
ing, recover $25 to $50 per month in amalgam which
would otherwise be swamped in the concentrates or
lost in tbe canyon. Under slipshod milling this box
catchment might easily pay the mill payroll. This
for twenty stamps.

4 inches to the foot, there will be no clogging with
sand and sulphurets, and the amalgam catchment
will be heavy. Foundries will ordinarily cast a mor-
tar with 14 inches to foot grade on the lip. This will
surely clog and prevent the amalgam from catching
on the lip plate.
Let the pulp drop from the mortar lip (usually 14
to 3-inch drop) upon a sheet iron strip 6 inches wide,
whence it flows upon the copper plate. A drop of
over 4 inch will scour the silver. Under the splash-
board B is 4-inch strip of sheet iron over the plate to
prevent scour.
Launders. — If of wood, let them be V shape, set
to grade of 14 inches to foot.
Rock Breakers. — Every mill should have two
rock breakers, coarse and fine. Set the jaws of the
coarse breaker 4 inches apart, so that a sledge can
slide through, thereby avoiding the breaking of the
pitman or side rods. Dump all the ore, coarse and
fine, as it comes from the mine, directly into this
large breaker. The mixing of fine with coarse pro-
longs the life of the jaws. The crushed ore to pass
over a grizzly — the fines going to the feeders, the
coarse to be crushed in a second breaker. Manga-
nese jaws are the most durable. Same material for
mortar liners.
Grizzly. — Grizzlies often give much trouble by
clogging — the rock begins to build against the thim-
low costs per ton to their mining and milling record.
I believe in getting through all possible, consistent
with full recovery of the gold. I can not bow down
and worship a given type of mortar merely because it
is a rapid crusher. High duty should mean low
tailings.
The narrow, straight-back mortar, with low dis-
charge, is not a new idea. The foundries are full of
old patterns of this type. All our cement gravel
mills are so built. For myself I can not escape the
conviction that it is not enough to crush rock; one
must also catch gold. I am constrained by my own
experiments to believe that many are enjoying high-
grade tailings because they sacrifice amalgamation
to crushing.
Taking up now seriatim these four captions :
The Mortar has the Two Functions of Crushing
and Amalgamation. — Gold amalgam is a slippery
eel — it rolls and floats unless fairly treated. Give it
a show and it will settle in the mortar. It is not so
hard to catch fine gold inside the mortar if the mor-
tar is built for that purpose. So that I should say
the limit of crushing in a given mortar must be meas-
ured by the percentage of inside amalgamation, ex-
cept, however, on ores carrying values of $1 to $1.50
per ton of fine light gold. The aim should be to in-
crease the inside catchment — keep it above 60%.
The tendency of stamping is to combine the gold
with the mercury. It is natural that this amalgam
suicide to jump this crushing to 54 tons and the tail-
ings to 75 cents per ton. I would call it suicide, re-
gardless of whether there were 10,000 or 10,000,000
tons in the mine.
Use Stamp Mills on Quartz. — I suppose that
somebody will invent a better machine than the Cali-
fornia quartz mill for smashing rock and catching
gold. It has its faults, and yet its much condemned
sliming tendency is too often the fault of the millman.
Somehow I like it, because it is a simple, relentless,
conscientious brute, with fewer faults than cling to
many of its operators.
If you want to stir mud buy a coffee mill and stir
it. But if you have rock to crush, build a heavy Cali-
fornia stamp mill with the shoe 94 inches and the die
91 inches diameter — the whole stamp weighing 1100
pounds — 104 inches from center to center of stems.
The ends of the mortar, after the liners are in, should
be flush with the screen opening.
I have heard more than one man assert that his
ore did not require a heavy stamp ; but I have always
found that the man had never had the luck to try the
two weights on the same ore. If his ore on one mine
happened to be harder than at another he would en-
deavor to effect a cure by giving more drop to his
light stamp. If the rock still resisted and the stamp
bounced, he would settle back on the excuse that he
had very hard ore, for which misfortune he was not
responsible.

bles. The most satisfactory that I have ever used is
made of 12 or 16-pound T rail, downside up, bars 6
to 8 feet long, U inches apart, at an angle of 42° to
45°, the lower end of the rails rolled over, thus : (See
Fig. 5.) If not over 8 feet long, it will be unnecessary
to use a middle bar with its thimbles. The steep
grade will give a fine product — there will be only
occasional clogging.
So much for the working tools. Try for a mill site
with plenty of fall — not less than 55 feet from track
level to concentrator floor ; better 75 feet. Heavy
duty is exacted. Machinery is sure to break, there-
fore the working parts must be accessible.
Milling. — I hold fast to four central ideas: First
— On free gold ores the mortar has the two functions
of crushing and of amalgamating. Second — On ores
running less than $12 per ton the method used must
be such as to extract practically all the recoverable
gold. We will not now discuss $40 ore. If such is
your luck, you may do quite as you please — either
you will get rich and quit or the ore will quit.
Third — If the ore is hard enough to require a rock
breaker, build a heavy stamp mill, otherwise you
may use one of the various rotary mills. Fourth —
Do not skimp on rock breakers. It is the cheapest
initial crushing; one to the mill not enough.
There is a good deal said nowadays about high duty
of the mill, i. e. , large crushing. Directors relish
five and one-half tons to the stamp and superintend-
ents do not object to this high duty, because it insures
should stay inside; and it will unless the millman sets to
to expel it in his scramble after a high-crushing duty.
Extract Practically All the Recoverable
Gold. — Whoever has used quicksilver has lost gold.
Whoever has crushed ore has had uncrushed particles
of sand carry (stowed away inside the particles) some
atoms of gold. Therefore, tailings must assay some-
thing. It is a commercial question. You may be
able to afford some loss in order to get through a
larger tonnage. To illustrate :
Preparing a tailings sample for assay by screening
through a 40-mesh screen, we find that 2% of the
sand rests on the screen, and the fire assay shows
values of 5 cents or 10 cents per ton in the fine sands
and $1.50 per ton in the coarse.
The results may be tabulated :
98 tons @ 5c.
2 tons @ $1 50
100 tons
U 90
3 00
:$7 90
or @ 10c.
i. e., 8 cents to 13 cents per ton.
$9 80
3 00
: $12 80
I am quoting actual results, not giving theories.
The crushing was at the rate of 3 tons per stamp
through No. 2 tin screen.
This 2% coarse sand could have been saved by using
No. 1 tin, but it would have been at reduced crushing
tonnage and would have shaved close to the sliming
danger.
I call this extracting practically all the recover-
able gold. And I should say it would be business

My own luck has been different. I have had an
850-pound and a 1100-pound stamp on the same line
shaft and identical ore. The former crushed \\ to 14
tons per stamp and the latter 3 to 4 tons per stamp.
The little fellows could not get away with the job, no
matter what drop I gave them.
I may be all wrong. I am still open to conviction.
But my present frame of mind is that my church is
founded upon more solid rock than is the light stamp
theorist's. I am through with theorizing.
Now, then, how fast shall we run this heavy mill ?
What drop ?
We are mixing in with factors that belong to plate
amalgamation, of which I shall speak later.
I want a heavy stamp because I don't want to
waste time breaking rock. I want a shoe and die of
large area so as to embrace many pieces of rock at
every blow. If you reduce the crushing area from
9| inches to 8 inches you are compelled to make up
the deficit by speed or long drop.
Bring a sledge whack upon a bowlder. If you don't
break it you hit harder the next lick. You don't hit
oftener unless you get mad and so make a fool of
yourself. Probably you will strike slower — you get
there by muscle, not by agility.
So it must be with a stamp mill. Stamp crushing
is not a question of spalling rock — it is to crush and
amalgamate ore that has been, as it were, already
spalled by the rock breaker.
It happens that I am now running a mill upon un-

usually tough, hard ore — first-class road metal some
of it. And this is what I find : With a speed of 92 to
114. and a drop of (J inches to 7 inches, an 1100-pound
stump will crush about eighty tons in twenty-eight
days, and save all the gold. Increase the speed to
10O to Hi-, and the drop to 8 inches to 9 inches this
same stamp will crush about 110 tons in twenty-eight
days, and by no means save all the gold.
So, then, my rule is to get weight and area of
stamp, so as not to waste time, and to drop as the
tailings assays dictate.
High speed means more wear and tear, hot boxes,
greater percentage of breakdowns. If you can
reach the limit of profitable amalgamation by a
slower speed why not do it 1
Railroad men run trains 14 to 18 miles an hour, not
because they are regardful of your neck, but because
they save wear and tear of rolling stock.
I have never run a stamp heavier than 1120
Founds, and from what I have learned and been told
am not aching for any greater weight.
I have found it easy to crush more than I can amal-
gamate. It is for this reason that I am unable to
give assent to the theory of installing a system of
rolls and crushers so as to deliver a cracked corn
product to the stamps. For some mysterious reason
there is benefit to amalgamation by churning rock in
a mortar. I am no sufferer if it does take a little
Here, then, are two men standing each a 12-hour
shift, equals 336 hours in the fortnight ; 92 hours of
the 336 they were running rock breakers. Evidently
these men have time to eat and to attend to other
duties.
The rock-breaker end of the mill is too much
neglected. One is not enough to any mill. On the
other hand, I see no gain in going to the other ex-
treme of too minute rock-breaker crushing.
Let us now cut deeper into the matter :
Catch the gold close to the die.
Don't use chock-blocks or inside coppers.
Don't slime by too fine crushing.
Don't crowd tables with too much pulp.
Don't sluice the pulp over the plates.
Don't add water outside the mortars.
Don't be afraid of steep grade to tables.
No distributing boxes.
Don't turn all the pulp on one-half the plate area
when brushing up.
Don't scrape plates with chisel or rubber. Rub up
with a cotton cloth and tepid water. Lip plate,
however, is scraped off monthly with a chisel.
Peed quicksilver so carefully that never a globule
of free quick appears on the plates.
Feed low ; i. e., regulate the feeder so that the
shoe is kept just cushioning on the die.
Run the batteries with the splash and not with the

more time in the making of the butter. If the mine
needs more stamps buy them.
Before a 5-stamp battery 5 feet width of plate
seems to be the practical limit. Six feet is too wide,
and 5 will give better results than 4.
I have tried a launder before ten stamps, the pulp
I being thence passed to three tables each 4 feet wide.
I This was a failure. By no adjustment of gates and
|l water could even distribution and flow be obtained.
H One table was all sand and another all slimes. The
I wave, the crescent bow, was not there.
Don't skimp on rook breakers. One breaker to
• | the mill is the rule, and ordinarily this means that
much of the ore going into the feeders will not pass a
2J inch ring. It would not cost much to cut this
product to 1-inch ring size, and a very noticeable in-
crease in crushing will result. "With a 1-inch ring
product there will be fewer broken stems and conse-
quent delays.
I have a 12xl6-inch jaw crusher, into which is fed
all the ore as dumped from the cars ; thence the
coarse rock from the grizzly is fed into a No. 1 Gates
or 8x12 Blake. We have twenty stamps, one mill-
man and one rock-breaker man on each shift. These
two rock-breaker men you must have, as they assist
the millman, look after the sulphurets, etc.

wave motion.; i. e., lift the shoe above the water at
every blow.
Use automatic sampler on tailings.
Avoid the use of acids and cyanide on plates ;" com-
mon lye will cut grease.
Keep the quicksilver clean by retorting and then
washing well with dry lime — follow this treatment
with thorough washing in clean water.
Use well silvered plates. When they turn green,
replate them, and don't waste time and gold over
nostrums.
Catch the Gold Close to the Die.— This requires
a roomy, rather than a narrow mortar. You can't
churn butter in a teacup, and you must churn if you
want to amalgamate. I am now using two styles,
both 1100-pound batteries. There is no difference in
crushing, but the Fig. 1 mortar invariably makesthe
larger inside catchment. The other mortar is straight
It is a pretty safe rule to grab $20 when you see
it, provided you can do it conscientiously. If you
don't, something else will. I have found that when-
ever I neglect my inside catchment the tailings run
up. Set the discharge too low and the mortar will
throw out on the plates. It is the province of the
plates to catch the fine gold, not the coarse. Coarse
gold will roll down hill, and the table is a downhill
proposition. Coarse gold makes good sized bits_ of
amalgam, and the natural habitat of these is inside
the mortar.
I should say that on quartz the discharge must not
be less than 5 \ inches at the start, i. e., ,5} inches
depth of water measured from the top of the die to
the bottom of the screen opening. Starting with
this you will soon have 53 inches discharge. We will
say now that the wear of the die is 2 inches in twenty-
eight days. This would mean 71 inches discharge at
close of the run, and would diminish the crushing.
To cure this make one screen frame with 3-inch
strip on bottom and 2 inches on top edge ; make an-
other screen with a 1-inch strip on bottom.
As the run progresses you can change and turn
screens so as to preserve a practically uniform dis-
charge.
The drop is regulated by the tappet.
There is no harm in using a b'* to7J-inch discharge.
But there is no gain to amalgamation, and you dimin-
ish the crushing capacity of the mill. In other words,
work so as to obey the injunction, "Get through all
possible consistent with full recovery of the gold."
Some interesting experiments were made at the
Utica and Gwin mines on mortar shapes for 900-
pound stamps. The back of the mortar was straight-
ened to 77°. At the discharge line the distance from
shoe to back is 1\ inches and to screen 5J inches. It
was found that this mortar would crush 5 to 5J tons
to the stamp on Utica and Gwin ores, whereas the
wide mortar crushed 4 to 4J tons — this with No. 2 tin.
I attempted to apply these lines to an 1100-pound
mill, but did not increase the crushing, and can only
attribute the failure to the fact that the heavier and
larger shoe makes a more vicious splash. You can
not bring the screen closer than 7* inches to the
shoe. On identical ore the Fig. 1 mortar will out-
crush this straight back Utica mortar, and it is a
better amalgamator. Outcrush it because of the
greater weight and shoe area.
No Chock Block or Inside Coppers. — A copper
plate in the mortar will attract amalgam. But cop-
per is no greater magnet than is amalgam itself. Start
a bed of amalgam in some secure cranny around the
dies and you will have as eager an ally. Grooves in
the liners are all humbug — they only shorten the life
of the liner.
Nobody ever used a chock block but has seen it
build with amalgam, and has also seen it scoured red,
in whole or in spots — scoured, we are told, accident-
ally. Let us dissect this " accident."
Every battery is liable to be filled up with sand.
Feeders fail, faucets choke, millmen yawn or are
busy elsewhere — no matter the reason, true it cer-
tainly is that every battery fills up sometimes. It is
this fill of sand that scours the chock block. Amal-
gam once scoured off, is rebellious metal — it is round
and hard, it gets out on the plates where it rolls and
tumbles', scorning to stick, content only when it lands
in the concentrates or in the canyon. If in the can-
yon, it is lost for all time. If Selby happens to get a
bit of it into his sample he rejects the sample as ab-
normal— Selby may be appropriating, he certainly is
not buying abnormals. The millman blames the acci-
dent he himself has concocted — he has sandbagged
himself. For the chock block lies within the zone of
scour. Study this diagram Fig. 6.
Particles of gold and amalgam are flying about
within the area abed.
These particles can be attracted upward to the
chock block or downward below the line 3, 4, as you
please. If you use a chock block they will fly to it.
If you don't, they will sink around rocks — every par-
ticle lodged will attract another; soon it will be a
mass. But note the difference; the chock block
lying within the zone of scour 1, 2, 3, 4, your caught
amalgam is in danger of loss. The zone 3, 4, 5, 6 be-
ing below the line of scour, your caught amalgam is
safe till clean-up day. Millmen may sleep, faucets
clog, feeders buck — your amalgam is safe.
Repeatedly do I find the entire front of my mortar
below the line 3, 4 one mass of amalgam — cakes
1 inch to ! inch thick — this on $5 to $7 ore.
Take the year through and you will catch more
gold inside without chock blocks than with them.
Another important advantage is that in case of
overfeed of quick this excess will be safely absorbed
by the mass of amalgam around the dies. Excess of
quick on a chock block is fatal — it sloughs off the
amalgam.
When one considers the varied duties of the mill-
man and the sudden variations of gold ores there is
full warrant for abandoning the chock block.
Don't Slime by Too Pine Crushing.— Especially
vicious is this practice on slate ores. The correction
can only be located by assaying the tailings through
different meshes.
If you slime, you are also wasting power by dead,
i. e., useless stamping.
Don' t crowd plates with too much pulp.
Don't sluice the pulp over the plates.
Don't be afraid of steep tables.
No distributing boxes.
Don't add water outside the mortar.
These five may be treated together.
It is not easy to set down in words just what the
conditions of the pulp should be. It is a question to
be determined by the eye. When you run up against
a millman who says he can run his mill by ear, fire
him. Sand does not make much noise as it flows over
Perhaps if you will let the mind dwell upon these
negatives, some idea of my meaning may be realized.
Plate amalgamation and ground sluicing are two
different arts. Gold is caught on plates because gray-

ity settles the metal to the silvered surface. There-
fore, don't be in such hurry to get rid of the sand,
and try not to throw obstacles in the way of the laws
of gravity. Gold and mercury have their full share
of specific gravity, but upset the conditions and you
easily offset this factor.
The pulp must not be too thick on the plates — you
don't want a double deck of sand. Furthermore,
there should be an even flow of water over the entire
plate area. It is for this reason that the center of
my plate is T\-inch below the edges — to draw the
water away from the edges. Batteries tend to a
greater discharge in the corners than in the center.
It is a common sight to find a rush of water 4 inches
to 6 inches wide along both edges of the table — one-
fifth to one-fourth of the plate area is overflooded.
Many mills have tables 24 feet long with no break
in grade. Drop a cork chip at the head of such table,
and at the same instant another chip at the middle.
You will find that the second cork will travel its 12
feet in less time than the first one, because the veloc-
ity of flow must be accelerated on such a table. If
the flow is correct for the first 12 feet, it must be
wrong for the second 12 feet.
It goes without saying that tables should be of the
same width from top to bottom.
The sand should move over the plates slowly and
evenly ; the water will go in waves or pulses, while
the sand below it will be kicked along by these suc-
cessive waves, not moving any faster over the last 2
feet than it does over the first 2 feet of the table.
Between the waves the sand almost, but not quite,
comes to a standstill. Note this point especially :
The sand is kicked along ; it must never be swept
along by a heavy flow of water.
Have a wave and use it. It is these successive
kicks that tumbles the sand about ; before the last
plate is reached the gold is kicked into its proper
place, viz : to some sticking point. The i-inch drop
every 2 feet assists the process in two ways : (a) the
drop bowls the particles over ; (b) it prevents accel-
eration of flow.
With this thin, carefully regulated flow and a sticky,
pasty plate, good amalgamation will be had.
One reason for the excessive use of water, so com-
mon, is that the table has too little grade.
The millwright turns over a table lj-inch to lj-inch
grade to the foot. It should be 2J-inch to 2|-inch.
Don't be afraid of steep grades, for it means less
water and clean table ; no danger of scour.
Distributing boxes are an abomination. The holes
get plugged up ; they incite the millman to careless
use of quicksilver when rubbing up ; they are traps
to gather quicksilver, and let it out in lumps on the
plates ; they don't distribute pulp as evenly as the
plain splash board (Fig. 2).
Globules of free quicksilver on the plates should
never be tolerated. If there is a distributing box
the millman can lay the blame to the box. Take
away the box and rob him of his excuse.
Don't add water outside the mortar. I think one
needs just the same amount of water inside the mor-
tar as out, and I know of no better guide as to how
much water to use in the mortar than to use just
enough as will move the pulp properly over the
plates. No reliance can be placed upon stated form-
ula of so many gallons per ton of ore.
I regard this point of quantity of water as vital,
and so far as my observation has gone nine millmen
in ten use too much. Not one of these nine will agree
with me in this — which only shows how obstinate men
can be.
Don't turn all the pulp on half the plate area when
brushing up.
We have all seen the 4-foot plate with partition
strip in center. The battery is not hung up when
brushing the plates, but all the pulp is turned to one
side of the strip, while the men are working on the
opposite side.
It seems to me there can be no logical defense for
this custom. If 4 feet width is needed at any mo-
ment, it is for all the moments. To confine all the
flow to 2 feet width must inevitably scour. The only
excuse urged is that it does not pay to hang up. I
hardly think it pays any better to scour — the richer
the ore the greater the loss. Build another battery
if the mine will stand it. The average mine will sur-
vive the shock of a little hanging up.
The champions of the never-hang-up theory seldom,
if ever, sample tailings when brushing up. They
don't know their own losses. It is a well-known fact
that upon ore of only $8 value the plates just before
brushing up will be plentifully sprinkled with coarse
bits of amalgam barely hanging on against the flow.
I suggest, by way of proof, that three tailings sam-
ples be taken from the 4-foot plate width within the
ten minutes preceding the rubbing up, and then three
samples from the 2-foot plate width during the ten
minutes of rubbing up. Do this for thirty days,
making careful assays of all the samples. Note the
per cent of assays abnormally high due to particles of
amalgam.
I hold that it is not sufficient to reply that what is
lost in amalgam is recovered in the concentrates.
Every concentrator passes more or less of amal-
gam and mercury over into the tail race.
Don't scrape main plates with chisels.
No globules of free quicksilver on plates.
It is essential to keep a well silvered surface, sticky
and pasty. The apron plate may require replating
every three or four months. The lower plates should
wear several years. The cost of replating varies
with the ore. I have found it amounts to 1 to 1£
cents per ton crushed, using a plating of three ounces
silver per square foot of plate.
I take off every morning the excess of amalgam,
but never skin it closely. Rub up with a piece of
cotton domestic several folds thick, sprinkling the
plate with quick from a small shaking bottle. I have
seen used a beer bottle with quill through the cork ;
but this wholesale fashion of sousing quicksilver on a
plate is malpractice. Use a small vaseline jar with
rocker 4 feet long by 16 inches wide ; a clean-up
board 5 feet long by 12 inches wide, with 3-inch side
rails, covered with a silvered plate; a buck and a
wedgewood mortar; a small iron screen J-inch mesh.
Into the trough throw all the mortar dirt; sprinkle
freely with quicksilver; turn in boiling hot water; then
hoe the mass about thoroughly with hoe and strong
four-tined rake so as to break up all lumps. The dirt
is then rocked out and the resultant amalgam, iron
scraps and fine sands dumped upon the clean-up
board and the sand washed out with a hose stream.
The iron is taken out by magnet. Grind the amal-

a piece of cotton tied taut over the mouth; clear, tepid
water in a kettle to dip the rag in frequently. Rub
the plate briskly and thoroughly, being careful every
day to remove all blisters of amalgam. These blisters
eat out the silver, and therefore should not be per-
mitted to form. In cold weather they are especially
troublesome. If they stick too tight for the rag,
they may be gently scraped off with a piece of No. 24
stove pipe iron shaped like a flat scoop 2 inches wide.
Do not use a steel chisel. Finish with a final light
sprinkling from the jar and thorough rubbing with
the cotton rag, then brush over with a whisk broom.
The lip plates are never softened with quicksilver,
but are every morning brushed off, or rather scrubbed
off with the broom to clean out the sulphurets. The
lips will stand a good stiff brushing daily.
At 4 o'clock p. M. and at midnight my plates are
again rubbed up, but no amalgam is taken off at
these times. It therefore takes only a few moments
for these two rubbings. I find that my running time
on a 20-stamp mill is twenty-three hours daily be-
cause of this careful plate treatment.
There are never any globules of free quicksilver on
the plates, top or bottom. If the ore is lean, we feed
less in the battery and the rubbing up is so carefully I
done that it never leaves drops of quicksilver on the j
plates.
The quicksilver fed is weighed at every shift in
troy ounces and a daily record kept. I never weigh
out an allowance to my millmen. They know what is
expected and careless work reveals itself immediately
on a plate. At clean-up there should be little or no
free quicksilver in the mortars around the dies.
Battery water at 55° Fahr. will give good results.
It is essential not to have sudden changes. I never I
saw a reliable mechanical heater. Perhaps, where
oil is cheap, the incubator racket would work. '
I rely upon keeping the plate room warm because
I am afraid of the sloughing off of amalgam, which
inevitably follows a sudden rise of 20° to 30° of the
water. I am still studying on the problem to keep
the water uniformly at 65°.
Automatic Sampling. — The custom of sampling
tailings with a dipper by hand every half hour, more
or less, has but little to commend it.
It is to the owner's interest to know exactly what
the tailings assay. It is to the millman's interest to
keep the tailings low.
The hand sampler will soon learn how to sample
judiciously from his point of view.
Nobody can coach an automatic sampler driven by
machinery.
It is absurd to take off the sample by hand from
the tail of the vanner.
There are several kinds of excellent automatic
samplers in use which I will not take the time to de-
scribe. However the sample be taken, it should be
evaporated to dryness for the assayer. Do not pour
off the clear water ; you may use a siphon.
Clean-dp Apparatus. — To clean up I use: A
wooden trough 5x2x2 feet; a man with the hoe; a '49
gam a few minutes in the buck- mortar ; rewash on
the board, giving a final bath of quicksilver in a]
wedgewood mortar to skim off the dross. To make
sure there are no lumps or bits of iron, copper or
brass, strain through the J-inch screen and regrind
the lumps.
I venture the assertion that by this process two
men will in two hours clean up a 20-stamp mill and
leave not over $50 in the sands.
These sands are, of course, put back in the bat-
teries at the following run.
I would clean up a 100 or a 500-stamp mill by the
same process, except that the mixing would be done
by what the macadamizing men call a " rattler " or:
revolving trommel. Rattler and rocker to be driven
by power.
Clean-up barrels and pans flour quicksilver and
thereby entail unnecessary losses of gold.
The clean-up room should have a cement floor. All
wash water should pass into settling boxes or tanks.
Concentrators. — Concentration is too broad a
question to be discussed here ; so much depends upon
the characteristics of the metals and the gangues.
In too many mills the crew is inadequate, so that
both batteries and vanners suffer alternately, as the
solitary millman trots up and down stairs vainly at-
tempting to straddle too much job. I never saw a
dozen belt vanners in any mill all working right for
over five minutes at a time. This may sound like an
exaggeration or a confession of bad luck ; in point of
fact, it is merely naked truth.
For the average gold mill the concentrator ques-
tion may be summed up in the rough about thus :
Buy one that is not over-sensitive ; there is- a wide
difference in this respect between the various belt

500
vanners ; don't pay much heed to the advertised com-
petitive tests.
It is because of their extreme sensitiveness to vari-
ance of load or water that I am disposed to think that
the reign of the belt vanner is about over.
What is wanted is a machine with some common
sense — one that won't kick and go awry at every lit-
tle variance of pulp.
The belt vanner is about as helpless as an infant ;
it seems to require some experienced old hen camped
alongside it all the time. That's the way the makers
conduct their misleading competitive tests. The
mined by assaying tailings.
Catch the gold close to the die.
Renounce chock blocks.
Don't slime by too fine crushing.
Beware of too much water.
Don't crowd the plate with too much pulp.
Have the plate sticky and pasty with amalgam,
and never dripping with quicksilver.
Use a broad, steep plate and hang up when rubbing
up ; note the use of the word rub, not wipe. Put
elbow grease, and none other, on the plates.
Don't be parsimonious about replating.

trouble is there is not much time for the nursery
business about a stamp mill.
The Wilfley concentrator requires a heavy load to
do effective work — twenty to forty tons. Conse-
quently, there would seem to be no room for it in a
5-stamp mill. Possibly a smaller table would scale
down to, say, a 10-ton load. Manifestly, any concen-
trator with so wide a range as twenty to forty tons
will not be going wrong every five minutes.
It is worthy investigation, and it is idle to object
that it has no belt.
Costs. — To close with some details of cost per ton
in 20-stamp mill — based upon a year's average —
16,000 tons :
Freight, $1.10 per cwt. from San Francisco.
Wages: Amalgamators, $3.50; rock-breaker
men, $3.
Water power: Rock breakers 0102
Water power : Batteries 0884
Labor, all, including repairs 2862
Shoes, dies, mortar liners 0721
Oil : Light and lubricating 0131
Replating 0100
Sundries 0024
Firewood (4600 feet altitude) 0081
Rockbreaker jaws, tappets, bosses, extras. .0130
Quicksilver loss, .145 troy ounce per ton. . . .0052
Total per ton crushed 5087
Quicksilver loss includes the mechanical losses from
retorting, cleaning up, etc. Nothing phenomenal,
you note. It is, however, authentic. The tailings
ran from 5 cents to 20 cents. The ore at the
monthly clean-ups ran from $4.75 to $10.25 per ton.
Recapitulation. — To recapitulate; my argument
runs in about this wise:
Use a stamp mill because the sons of Adam have
not as yet invented a better machine for the purpose
in hand.
Use a heavy stamp because it won't waste time
and can be run slow enough to save wear and yet
fast enough to churn and therefore amalgamate.
Have large shoe and die areas, so as to embrace
plenty of rock at every blow.
Crush and also amalgamate, the limit of your
crushing to be taught by the tailings assays.
Extract all the practically recoverable gold. If
more stamps are needed, build them.
The speed and drop suitable can only be deter-
Sample automatically.
Battery water temperature not below 50° Fahr. ;
better keep it at 65°.
Have a good mine; do these things and the great
god of battle, with whom every man must reckon,
will be with you.
Joshua Hendy Machine Works, San Francisco.
Few of our readers to whom the advertisements of
the Joshua Hendy Machine works are familiar real-
ize the prominence of this well known institution,
ranking as it does among the largest of manufactur-
ers of mining machinery in the West.
Years ago it became apparent to the Hendys that
the larger foundries and machine shops would be
compelled to leave the old district south of Market
street, San Francisco, where all the pioneer foundries
were located, and in their judgment they properly
established a nucleus for their growing business by
locating on the block bounded by Kearny, Bay, Fran-
cisco and Dupont streets, San Francisco, and oppo-
site the sea wall.
The Hendys, having been identified with the mining
industry over forty years, and having by their own
efforts created a demand for their machinery, it
naturally follows that their plant has reached the
large proportions shown in the illustration on the
front page in order to facilitate the execution of
increasing orders in their various lines. The recent
purchase of adjacent property will enable them to
erect additional buildings and materially aid them
in keeping up with the times in furnishing modern
mining machinery. Their San Francisco city office is
38-44 Fremont street.
Weber Gasoline Engine Works.
On the front page of this issue appears an illustra-
tion of the main office and works of the Weber Gas &
Gasoline Engine Company of Kansas City, Mo., a
company closely identified with the development of
the gasoline engine as applied to mining equipments,
hoists and pumping outfits, turning out gasoline en-
gines for all purposes from 1 H. P. to 100 H. P. ca-
pacity, the new plant illustrated covering a ground
space of 300,000 square feet. The new factory site
covers two entire city blocks, on which is built a sin-
gle-story factory of stone and steel throughout, mak-
ing it entirely fireproof. It is divided into five main
departments devoted to gasoline engines and hoists,
electric lighting engines, marine engines and auto-
mobile engines. Each department is equipped with
electric cranes, by which heavy castings are handled
conveniently. The power for operating these cranes
is supplied by an electric plant driven by gasoline en-
gines. Gasoline engines are used throughout the fac-
tory, separate plants being installed for the several
departments, the company being thus enabled to pre-
sent a practical demonstration of one of the most im-
portant advantages to be derived from the use of
this class of motors. Gasoline engines are placed
at convenient points and supply the power for oper-
ating machinery and tools in the different depart-
ments. The records of the company show that this
is an economical arrangement.
" The Light of Genius."
To the Editor :— C. M. Fassett has an article in
the issue of Oct. 20th on "The Selection of a Work-
ing Process," which is so good and sensible through-
out that one is surprised to find in it a piece of ad-
vice fraught with gravest danger to the inexperi-
enced, for whose benefit the article was evidently
written. I refer to the following: "Send part of
your ore to the smelters, and to any crazy scientist
who, you may hear, is working on a new process.
Take time to let them all have a trial at it, and re-
member that as no two ores are alike yours may be
just the ore that is adapted to some embryotic
method that will treat it succesfully. When they
have solved the problem the world sees the dazzling
light of genius in their eyes."
It is hardly necessary to point out that " crazy
scientist " is a contradiction of terms ; every mining
man knows the class to whom the epithet is applied.
One could hardly throw a club in the streets of San
Francisco without hitting the inventor of, or the in-
vestor in, a machine or scheme that was to " revolu-
tionize the mining industry ; " yet the mining indus-
try has never been revolutionized. Its wonderful
progress has been the result of evolution, never of
revolution. Mining men are constantly looking for
improved methods, and finding them, too, but not in
the workshops of the "crazy scientists." To advise
the inexperienced mining man, in search of a process
for treating his ore, to consult a " crazy scientist,"
or, in other terms, impracticable theorist, is to ad-
vise him to commit hari-kari.
The experienced mining man knows him by sight,
or, at least, by sound ; but the inexperienced is too
likely to mistake the glare of insanity for the ' ' light
of genius, " and present himself, a living sacrifice or
a burnt offering, on the altar of " embryotic meth-
ods." With a less stretch of imagination than these
theorists are generally endowed, one might almost
play hop-skip-and-jump from Montana to Mexico, on
the tops of smoke (less) stacks erected by " the light
of genius," and abandoned by the light of experience.
There is no reasonable excuse in these days for a
mine owner to make a vital mistake in selecting a
method to treat his ore. If he has ore of the required
formula, q X q = p (quantity X quality = profit), he
can learn how to treat it successfully by consulting
oue or more of the great mining machinery manufac-
turers whose names are familiar in mining circles
all over the world. And if some of these gentlemen
can not advise him, even to the point of a guarantee,
how to treat his ore properly, the sooner he quits
that particular mine the better.
When his reduction works are completed after
plans approved by experience; when the time of Irish
dividends has passed; when his proposition is on vel-
vet, and he has money for foreign missions, it will be
soon enough to monkey with " the light of genius."
F. N. F.
Without assuming to speak for Mr. Fassett, who
is at present in Corea, it is probable that the words
" crazy scientist " in his article are not taken as a
belief that the scientist is "crazy," nor are they to
be assumed as suggesting that it would be good busi-
ness to send part of the ore to any one who is
"crazy," be he scientist or otherwise. Probably
Mr. Fassett intended ironical allusion to the belief
still prevalent in some quarters that men who are
experimenting with ores and metallurgical processes
are "crazy" in their aims and intents, while in real-
ity they are, ofttimes, avant couriers of new metal-
lurgical discoveries. The context of the article would
seem to indicate that such was his intent, and that in
that way he meant to convey brief censure on the too
oft used notion that because a man in an assay office or
a laboratory does not produce immediately profitable
results, he must be " crazy" in his experiments and
embryo processes. Probably men not knowing any
better who first saw the pioneers in the cyanide pro-
cess in their crude experimental work, considered
them " crazy scientists," but it is from the work of
such " crazy scientists " as these that much of the
present mining and scientific progress is due.
Regarding the last sentence that our correspond-
561
Mining and Scientific Press
December 1, 1900.
ent quotes from Mr. Fassett's article, it would ap-
pear to us that that sentence is merely another way of
saying in a semi-sarcastic manner that success is the
criterion of merit ; that results determine what place
a man shall occupy in the esteem of his fellows ; and
that the obscure light in which the " crazy scientist "
of to-day may be working, in the event of his success
may develop into a halo of light, irridating and sur-
rounding him as a genius, when success is made mani-
fest. The diver, as he poses to plunge, may be a
pauper, but, as he emerges from the depths with a
pearl, may be possessed of the wealth of a prince.
And so with the scientist, the inventor, or the theo-
rist, who, if his science, invention or theory is based
upon fact, may emerge from the shadow of universal
disbelief to the splendor of noon-day success, and be
hailed as a " genius," because successful, yet not the
less a genius before.
It is believed that from this point of view Mr. Fas-
sett's remarks are not wholly open to the interpre-
tation of our correspondent, though from his stand-
point and construction of the meaning of the article
to which he refers his position is eminently correct.
The latter is certainly right in the statement that
there are a great many men who never get beyond
the "crazy" stage in mining and metallurgical pro-
cesses, but that is because their conceptions or
theories were never susceptible of successful demon-
stration.
There is a wholesome conclusion to be derived from
our correspondent's suggestions, namely : that it
were better for mine owners and operators to let
others do the experimenting ; to disregard anything
that has not been proved to be good ; and to profit by
wise observation rather than costly experience.
Pyritic Smelting in the Black Hills.*
NUMBER III.
The slag and matte at Deadwood run together
from the end of the furnace into a forehearth, either
3x5 or 4x4 feet in size, and 2 feet deep, where the
matte settles in the bottom, while the slag overflows
into large slag trucks. This forehearth is upon
wheels high enough to run a matte pot under its tap
hole. As fast as the matte accumulates, it is tapped
from the bottom of the hearth into a pot. The fore-
hearth is lost, usually by the accumulation of metallic
iron or "sow," that raises the bottom above the tap
hole. These forehearth sows are identical in com-
position with those formed in the interior of the
furnace, and are treated in the same manner as
the furnace sows. Owing to their small size, they offer
no difficulty in the way of handling or breaking up.
They usually weigh from 800 to 1000 pounds.
It was my theory that this metallic iron helped to
clean the slags, and I did not really care to over-
come its formation ; but others have tried to do so.
It was my theory that if the gold were not recovered
in the sows, it would be lost in the slags ; and here is,
in my opinion, the solution of the question of clean
slags in the use of iron pyrites free from copper.
The Deadwood iron matte was never a pure mono-
sulphide, but a subsulphide carrying metallic iron,
some of which could be separated as " metallics "
by grinding and sifting. Traces of copper existed,
while the matte always carried silver and arsenic.
The traces of copper, silver and arsenic would, of
couse, take it out of the experiments of Dr. Pearce,
to which reference is above made ; but to my mind it
was the metallic iron which cleaned the slags.
In a discussion of this question before the Colorado
Scientific Society, it was remarked that if Dr. Car-
penter would add more pyrite, he would avoid sows.
It is a question whether, with our slags, this would
be the case. At Kongsberg, where pyrite is added
to the smelting as we added it at Deadwood, Samuel-
son found that an increase in pyrite meant an in-
crease in the metallic iron so reduced. This was our
experience at Deadwood. The formation of sows
could be lessened, however, by cutting down the
amount of coke used, and thus lessening the reducing
action of the furnace. As this invariably meant an
increase in the amount of gold lost in the slags, I
aimed always to make some " sow."
Before it was possible to obtain copper it was Mr.
Znutzen's idea that it paid to add waste metallic
iron to the charge, purposely, to make sure of the
presence of metallic iron in the furnace.
I believe that a process for smelting the Siberian
black sands, so that the gold might be recovered in
metallic iron, was once proposed. From our experi-
ence at Deadwood, I have not the least doubt that it
would have been successful. Even after we obtained
the copper ores from Butte, the amount of " sow "
was in no way diminished. At Mansfield it has been
found impossible to prevent the formation of these
sows, although there they serve no possible purpose
unless it be to collect the small traces of nickel and
*F. R. Carpenter, August Meeting, 1900, Transactions A. I. M. E.
cobalt in the ores. As the pyrrhotite was not known
to be nickeliferous, I often intended to have our
" sows " tested for nickel, but never did so.
The percentage of matte made at Deadwood is
very low, seldom exceeding h% of the weight of the
charge, and formerly sometimes fell to 2% or 3% ;
and here I wish to note a peculiar experience. Be-
fore the use of copper we could not always control
the percentage of matte to be made. Sometimes
almost the whole of the iron would go into the slags,
and no matte would be made. At such times one
would expect that the slags would carry the whole
of the gold, but such was not the case. They were
not noticeably more foul than at other times. I note
one run of eighteen hours without matte, while it was
common for hours to pass with little or no matte ap-
pearing. " Sow " was doubtless formed, but, if so,
it remained in the furnace, and with it the gold.
In the Altai mountains, where pyritic smelting is
practiced (I use the term " pyritic smelting " always
in the sense in which Percy first used it), the matte
frequently falls to 2% or Z%. "We found the matte,
however, much richer than usual, and I have made
iron matte at such times exceeding twenty-five
ounces of gold per ton. I am strongly of the opinion
that, if the reduction of iron can be controlled in this
form of smelting gold ores, copper may be disre-
garded, especially when it is handled at a great loss,
as at Deadwood.
Many persons have supposed that these high-
silica slags are made only at a high formation tem-
perature. Prof. Hofman, in a most valuable paper,
has recently investigated the temperatures at which
certain silicates are formed. In one series he gives
the result of the addition of silica the ordinary slag of
the lead smelter. He adds silica by regular steps,
and plats the result in a curve. The formation point
from 0.5 to 1.25 silicate degrees shows hardly any
variation. The slags are formed at about 1180° C.
The formation temperature then falls off rather rap-
idly until the bisilicate (2) is reached, and then less
rapidly to a point half way between the 2J and the
trisilicate (3). After the trisilicate, which is formed
at a much lower temperature than the monosilicate,
the curve rises very rapidly. At the basic end, how-
ever, the slags, he says, are very fluid, and melt
down very rapidly, while toward the acid end they
melt down rather slowly and are far from fluid, not-
withstanding their low formation temperature.

Oil and Gas Yielding Formations of
California.
NUMBER II.
The official State bulletin shortly to appear will
contain much of value to California oil men. In it
W. H. Watts says :
The oldest rocks exposed in the Sunset oil district
consist of sandstone, calcareo-siliceous rocks and im-
pure limestone, dark-colored shales, massive light-
colored shales — showing a hackly fracture — strata of
sandstone with rounded concretions, calcareous sand-
stone, and fine calcareous conglomerate. The expos-
ures of formation are scarce, and the few that exist
show great geological disturbance. Within short
distances the strata frequently dip in opposite direc-
tions and at different angles of inclination ; the pre-
vailing dip, however, appears to be northeasterly.
This formation yields springs of sulphuretted brines,
and in one place a small quantity of greenish oil
accompanies the brine, but no calareous tufa
nor any solid bituminous deposit is formed. No
fossils were found in these strata The most
characteristic features of this formation are the
dark-colored argillaceous shales, and the sandstone
containing rounded concretions. The stratigraphi-
cal position and the physical character of this
formation warrant the assumption that it belongs to
the same geological horizon as do the Eocene shales
and sandstones underlying the light-colored siliceous
shales in the oil district 9 miles north of Coalinga, in
Fresno county. Overlying the formations, which we
may tentatively class as Eocene, in the Sunset dis-
trict is a formation composed mainly of light-colored
siliceous shales and constituting the first tier of foot-
hills. These shales are for the most part of a brown-
ish color when first mined, but they become almost
white under the action of the atmosphere ; indeed,
the outcroppings of this rock are white or light-
colored for several feet beneath the surface. In
places the bleaching of these shales can be traced
directly to the action of sulphuretted vapor.
The light-colored siliceous shale is by far the most
characteristic rock of the bituminous formations.
Much of it is of low specific gravity and porous,
sticking readily to the tongue, and is easily scratched.
Some of it, however, especially in the lower portion
of the formation, is indurated, apparently by the
infiltration of siliceous water. Occasionally pieces of
this shale are found which show siliceous induration
only in the outer portions of the lamina? of which it is
composed ; a cross-fracture reveals soft, light-colored
shale within.
The chemical composition of these shales is as in-
teresting as their physical appearance, the charac-
teristic feature being the large amount of silica they
contain. Two specimens from the Sunset oil district
were examined which showed as follows :
Insoluble in SH|^„8^le Total amount
0/ OX 0/
so so so
( a ) .... 99 12 98,
( b ) . . . . 92 24 89
The light-colored shales are much less disturbed
than the formation on which they rest. The prevail-
ing direction of the dip of the light-colored shales in
the Sunset oil district is N 30° E., and the angle of
inclination is in some places as low as 20°, while in
others it is as high as 80°. Although the southern
limit of the light-colored shale in the district is toler-
ably well defined, it is not unlikely that in some
places, where this shale has escaped erosion, it may
extend a long way up the northeastern slope of the
coast ranges. In one instance a well was dug at an
altitude of nearly 3000 feet, in which light-colored
shales, similar in appearance to those found in the
lower foothills, were penetrated.
Investigations in various parts of the Coast Range
warrant the classification of these shales as Lower
Neocene (Miocene). There is reason to believe that
they rest non-conformably on the underlying rocks.
Numerous seepages of heavy petroleum exude from
these shales, forming beds of asphaltum, which, in
some places, before these deposits were mined by
Messrs. Jewett & Blodgett, extended over an area
of several acres. This asphaltum, much of which re-
mains, is principally black, pitch-like bitumen, vary-
ing from solid to viscous ; some of it is of a yellowish
brown color ; it is of different degrees of purity and
exists not only in beds and mounds, but was found by
excavation to extend beneath the superficial drift.
In some of these beds the bones of animals, stone
a'ortars and other Indian relics were found beneath
i or 5 feet of asphaltum.
In several places springs of brine and sulphuretted
water issue from the light-colored shales.
Near Coalinga, in Fresno county, the writer found
evidence of this formation resting non-conformably
on the light-colored shales, and in some places it con-
tained fragments of shale, apparently similar to the
light-colored siliceous shales previously mentioned.
At the Sunset oil wells and in the Coalinga district oil
sands are found in the lower beds of this formation.
The record of a well drilled in S. 28, T. 11 N., R.
25 W., S. B. M., is as follows. This well was com-
menced with a llj-inch casing :
Feet.
Sulphur and apparently tufa deposited by mineral
water to 45
Very hard gray and blue limestone to 80
(At a depth of 58 feet there was a little oil and
mineral water.)
Gray sandstone, with soft streaks and more mineral
water, to 160
(At this depth the casing was reduced to 8| ins.)
Soft blue sandstone, with hard shells and more
water, to 402
(At this depth the casing was reduced to 6f ins.)
Blue sandstone to 420
(At this depth the water was shut off.)
Coarse sandstone, with oil and watwr and much
gas, to 440
Light-blue sand to 445
Sand, with water, to 820
This well was cased from the depth of 420 feet to
that of 820 feet with 5-inch casing. Supt. Youle
states that this well was tested, and that about 100
barrels of brine and 6 barrels of oil were pumped
from it daily for three months. It also furnished
enough gas for a cook stove.

Packing Mining Machinery for Export.
On the front page is an illustration of six cases con-
taining mining machinery and parts at the shops of
the Gates Iron Works, Chicago, packed for ship-
ment to Johannesburg, South Africa. The illustra-
tion, specially made for this paper, is of interest; the
strength, security and marking will be noticed.
P. W. Gates, in American Trade, says the picture
shows fairly well the system and way of marking.
" Every package of every consignment is numbered,
and the gross and net weights, as well as the outside
dimensions of the package, are given plainly on sur-
face of box, and we usually try to put on such a sur-
face as will be below the general or outside dimen-
sions of the box, so that there shall be as little chance
as possible of this marking being erased. We would
call attention to the tin marking tag which is nailed
to each box in a recess cut out below the general sur-
face of the package. On all foreign shipments we
use this form of marking ; the letters on this tin tag
are stamped into the tin, and consequently will re-
main there as long as the body of the tag lasts. In
figures in the upper left-hand corner are the day
and the number of the month corresponding with the
date of the order, and this is done for the purpose of
identifying the consignment, so that the agent or
purchaser, even though he may have several con-
signments in his warehouse, and among these several
consignments several boxes marked No. 6, or any
other number, will know, by consulting this date
mark in the upper left-hand corner of the tag, to
which consignment this numbered package belongs."

(Special Correspondence). — The building
over the Gold Coin shaft is constructed of
brick, with roof supported by a steel
structure ; is of such design and finish as
to make an attractive appearance. The
interior is well arranged and includes
shaft house, compressor and engine room,
boiler room and blacksmith shop. The
gallows-frame, constructed of heavy Ore-
gon pine timbers, rises about 60 feet above
the collar of the shaft, the roof over the
sheaves forming a cupola to the main
building ; hoist cylinder 24i nches diame-
ter, 48-inch stroke, 12-foot reels for 3000
feet of steel cable. It is operated from a
platform, on which are hand and foot
levers. The disc strap and post brakes
are operated by compressed air, as is also
the reversing gear of the engine. The
shaft is three - compartment — two for
double-deck cages and one for pipe space
and ladderway. The depth of the shaft
is over 1000 feet
The air compressor is a cross-compound;
high pressure steam cylinders 20 inches
diameter, low pressures 34 inches. The
same figures apply to the dimensions of
the air cylinders. Both high and low
pressure cylinders have 36-inch stroke.
The steam cylinders have a position be-
hind the air cylinders. The flywheel is
grooved for rope transmission from an
electric motor in case the latter should be-
come the motive power, in which case the
steam cylinders could be disconnected.
This compressor i9 rated 400 H. P., with
capacity to operate twenty-four drills, and
it is calculated that a duplicate of it will
soon be put in to be operated by electric-
ity, hence the air cylinders to be left out
of the construction.

Victor, Nov. 24.
(Special Correspondence). — Recent im-
provements and developments at the
Granite mine, on Battle mountain, put
that property in first-class condition. A
new steam hoist of slide valve type, with
cylinders 18x36 inches and conical reel for
round cable, good for 1500 feet depth, will
be ready for operating by Dec. 1st. Its
power will be furnished by two boilers of
225 H. P. The shaft is now 1000 feet' deep,
having recently been sunk from the 800
to the 1000 level. Crosscuts have been
run from the shaft to the vein on the
ninth and tenth levels and upraises are be-
ing made to connect the two lower levels
with the upper workings at the eighth.
During the progress of this development
ore shipments have been merely incidental;
but, after Dec. 1st, a large tonnage will be
shipped regularly. The new shaft house
is ample and the shaft itself is well tim-
bered, and the character of the under-
ground timbering is the pride of those in
charge. Compressed air for drill power is
conveyed from the La Bella power plant
at Goldfield, a distance of 2500 feet,
through a 4-inch pipe line. This is one of
the Smith-Moffat groups. C. H. Cannam
is Supt. Wascott.

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co. 's Scien-
tific Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Combination Gun Cartridge.— No.
662,137. Nov. 20, 1900. H. A. Tellerson,
Oakland, Cal., assignor to Winfred Castor
of San Francisco. This invention relates
to an improved construction for gun
cartridges. It consists of a two-part base
with means for removably securing the
parts together. A paper or eqivalent
shell has one end crimped and clamped
between the two, and a pin secures the
two parts of the base in the interlocked
position. One of the parts of the base has
a hole with an inclined wall which is
engaged by said pin to allow for variations
in the thickness of the shell, and to insure
the alignment of the parts.
Design for a Calendar. — No. 30,366.
Nov. 20, 1900. M. C Hall, Bakersfield,
Cal. The leading or material feature of
this design consists of the representation
of a watch with a stem and ring. Arranged
within the inner periphery of the watch
are a series of small representations of
dials having figures indicative of the hours
and names of cities in different longitudes
around the world, hands on the dials
point to the hours, indicating the time in
those cities with relation to each other.
Interior to these small dials and con-
centric with the outer rim is a pictorial
representation of a globe, showing a part
of the world. The main dial is supported
upon a rectangular base which is subdi-
vided for the number of days contained in
a month. The ends of this base are con-
nected with supporting posts, one of which
has upon the top the figure of Time, with
scythe and hour-glass, and upon the other
the figure of the Goddess of Liberty. The
bases of the posts are represented as
spanning the Golden Gate, and upon each
side are views of the elevations of land be-
tween which the waters of the strait flow.

As in other forms of electric transmission, mine haulage is progressive. The
first electric mine locomotive was put in use in 1888, and in the twelve years
there is a notable advance in such application. Where min: conditions are such
as to admit of mechanical haulage, the electric locomotive presents many feat-
ures of economical efficiency that commend it to public consideration. The first
cost is necessarily high; but, figuring on the matter as an investment proposi-
tion where a degree of permanence obtains, the consequent saving in operation
and maintenance brings into view its economical features. Among other claims
in that regard are brought forward the statements that the use of an electric
haulage plant is economical because of freedom from complicated mechanism in
the locomotive; small friction loss; power consumed only when doing work, and
then in proportion to the work done; absence of heat, smoke, gas and steam;
inexpensive line construction; size of locomotive needing no extraordinary en-
largement of vertical entry section; locomotive wheel base, admitting of opera-
tion on curves of radii as short as 15 feet; light weight of locomotive for given
tractive duty and capability of operating on heavy grades; adaptability of the elec-
tric power to pumping, hoisting, lighting and other mine duties besides haulage.
On this page appear illustrations of various types of locomctives"_built by the
General Electric Co. Fig. 1 is of their standard mine locomotive, equipped with
cab and special draw-bars for surface work. This locomotive, as portrayed
herewith, is used by the Minnesota Iron & Steel Co., Minneapolis, Minn.; its
weight is 13 tons; draw-bar pull, 4500 pounds; speed, 8 miles per hour. Fig. 2
shows an electric locomotive used by the Bunker Hill & Sullivan M. & C. Co.,
Kellogg, Idaho. Supt. Barbridge says this locomotive hauled a train of
twenty cars, each weighing, when loaded, about 3500 pounds. Its draw-
bar pull is 1000 pounds; speed, 6 miles per hour. Fig. 3 is of an industrial
locomotive for inter-factory transportation, used by Balfour & Guthrie of
San Francisco. Its weight is 4000 pounds; draw-bar pull, 500 pounds;
speed, 8 miles per hour.
In the issue of Nov. 25, 1899, was given a description of the electric
traction at the Hidden Treasure
mine, Placer Co., Cal., with illus-
trations specially engraved for this
paper. Begarding the operation
of this locomotive, Harold T. Power,
president of the company, says
that, when operating by animal
traction, inotover^l80 tons of gravel
could on an average be hauled in
two shifts of ten hours each; with
the electric=locomotive an average
of 350 tons of material was handled
; during the same period of time.
I With animal traction it required
30 minutes to take in the men; the electric
locomotive made the trip in 8 minutes. The
locomotive runs steadily 20 hours a day, 6
days in the week. The issue referred to has
detailed figures comparing
electric with animal trac-
tion at the last named mine,
which are of value to any
one interested therein.

The latest addition to the much discussed subject
of the origin of the Yosemite valley, Cal., is by H.
W. Turner, a fine monograph just issued by the Cali-
fornia Academy of Sciences. Mr. Turner's position
and experience entitles his views to considerable
credence, and in very extended discussion of the sub-
ject he inclines to the belief that the Yosemite val-
ley " was formed by river erosion, facilitated by
strong jointing."
The importance of Cripple Creek, Colo. , as a gold-
producing district is graphically illustrated by
this year's gold output therefrom, which, it is now
estimated, will aggregate $23,000,000. In the last
nine years Cripple Creek has produced nearly $90,-
000,000 in gold, with a profit to the producers of
about one-half that amount, and estimates for next
year include a gold output for the ensuing twelve
months of $30,000,000.
The hysterical headlines in the dailies concerning
the alleged formation of a " great gold trust" that
is going to absorb and control all the principal gold-
producing properties in the world are not to be given
serious attention. Such a project is impossible from
the very nature of things, and none know this better
than the very men named as the projectors. Even
assuming that the airy scheme were an accomplished
fact, it could apply only to the present. Prospectors
and miners are daily developing new properties sus-
ceptible of great gold output, and the possibilities of
such further development are so great as to border
on the illimitable.
Copper stocks are attracting unusual attention.
Last week the $75,000,000 capitalization of the
Amalgamated Copper Co. was for the first time
quoted on the New York Stock Exchange. The
Anaconda Mining Co.'s stock was already on its list.
The Amalgamated Co. gives little information to
the Stock Exchange or any other public or private
organization as to its affairs, and though it regularly
pays 8% dividends, the general public does not
encourage such secrecy by purchase. The result of
the noted reticence is that while an 8% or even a 6%
dividend-paying stock ordinarily now sells for consid-
erably above par, the stock of the Amalgamated
Copper Co. sold last month, after its being placed on
the New York Stock Exchange, as low as 94#. In
general, however, at the present cost of production
and selling price, copper is considered in the East as
"a good buy." The Old Dominion, of Arizona, is
producing 10,000,000 pounds per annum at a cost of
seven cents per pound, which is indicative, in a
general way, of the present profits in copper mining.
Studying Mining Engineering.
There is a manifest connection between the big
salaries paid a few prominent mining engineers and
the enormous increase in the number of young men
" taking a mining course " at so many mining schools
and in so many colleges and universities. The prizes
look so big that the attraction is great, and, evi_
dently, a great majority of the young men now study-
ing in " mining colleges " look forward to the time
when they, too, will enter upon a successful career as
mining engineers at a fine salary.
It is to be sincerely' hoped that each deserving stu-
dent will win such a prize, but there is a difference
between getting one's degree in a college and getting
a good paying position, or, having such a position, in
successfully and satisfactorily holding it to the
mutual satisfaction of all concerned. Without decry-
ing the praiseworthy effort, the laudable ambition or
the hearty endeavor that impels a bright and capable
young fellow to try and fit himself for so responsible
a position, it is to be borne in mind that knowledge
is not judgment, that learning is distinguishable from
experience, that good intent is not proved capacity,
and that the graduate from a mining college is only
at the threshold of his- career. He finds the field
fairly filled by able men of experience, and, however
gifted or endowed with educated energy, he must
first learn something not possible to be learned in
college — how to use his head and his hands in practi-
cal work ; how to get on with others ; how to act
therein where so much depends upon such action; and
that there is considerable work of the hardest and
commonest kind that can only be learned by doing it.
Thousands go out of our colleges every year with
their heads full and their hands empty; crammed
with knowledge, but destitute of the " know how ; "
the proud possessors of degrees, but without cogni-
zance of the practical requirements of their chosen
profession, and then begins the dreary process of un-
learning— of unloading the useless lumber — and re-
taining the few clear, bright ideas that, coupled with
the knowledge acquired only by experience, will win
them place. Happy those who have the fortunate
faculty of forgetting ; for it is only in discarding con-
siderable of what they carry out of college that they
can ever hope to succeed.
This is not said to daunt the ardor nor deter the
effort of any young man who is seeking, through col-
lege, to fit himself for the position of mining engineer.
Under certain limitations and with certain provisos
he is on the right track ; but he should realize that,
while the college can and will do much for him, the
number of those who are likely to attain prominence
or profit is necessarily circumscribed, , and that once
in the field he can only get what he earns, and by his
work alone can he demonstrate his value amid diffi-
culties that do not exist in less arduous professions.
The field of mining engineering offers just about the
same professional rewards that any other lucrative
and desirable profession proffers. The young engi-
neer can not step from the college campus to a high
position ; he must show what he can do, and, as in all
other walks of life, the world will pay a man what-
ever value he sets upon himself just so soon as he
demonstrates that he is worth that. He must, how-
ever, despise not the day of small things, nor expect
to be immediately placed in charge of great enter-
prises. It is for him to win plumes and then wear
them. Happy he if he can learn the truth of this
without the set-backs, disappointments and heart-
breaks that so often prematurely age and weaken
the spirit of the young man who fails to realize that
the day he leaves college he is only beginning, and
that the best he may expect to carry away from his
alma mater is the trained brain. In this lies the great
advantage of college education, for it is a great
advantage to know what to do. The equally import-
ant advantage of knowing how to do it can, how-
ever, only be learned by subsequent work.
There is good in study and in college training: it
economizes time and cultivates mentality; its influ-
ence is for good and its development favors the cre-
ative powers. The study of mining engineering or
any other form of mining is to be commended when
under competent instructors, but the student should
remember that one must learn as long as life lasts,
and that when the college doors close behind him
the best and most valuable part of his education lies
before him.
Proposed Federal Appropriation.
Minining and scientific progress was practically
considered in the first session of the present Con-
gress by the introduction of a bill in the interests of
mining and metallurgy to appropriate yearly to each
State and Territory money for the maintenance of
schools of mines. Notice was made of the measure
at the time of its introduction. It will be remem-
bered that it provided about as follows : That there
shall be annually appropriated out of money from
the sales of public lands to each State and Territory
for the establishment and maintenance of schools or
departments of mines and mining in connection with
the colleges for the benefit of agriculture and the
mechanic arts, now established or which may be
hereafter established in accordance with the pro-
visions of an Act of Congress approved July 2, 1862,
the sum of $10,000 for the year ending June 30, 1901,
and an annual increase of the amount of such appro-
priation thereafter for five years by an additional
sum of $1000 over the preceding year, the annual
amount to be paid thereafter to each State and Ter-
ritory to be $15,000. Such appropriations are to be
expended only for geological instruction, mining en-
gineering, metallurgy, research in road-building ma-
terial and its proper application, and the branches of
learning pertaining thereto, including the various
branches of physical, natural and economic science
and the facilities for such instruction, research and
experiment, the idea being " to promote a liberal
and practical education and secure the most intelli-
gent use, conservation and development of the
mineral resources of the country." In any State or
Territory where a school of mines has been estab-
lished by the Legislature thereof, separate from the
colleges or universities hereinbefore named, the ap-
propriation is to be paid to such institution.
The bill further provides : "That a detailed re-
port of the operations conducted by the respective
schools or departments of mines, during each year
ending the thirtieth day of June, shall be transmitted
on or before the first day of the following November
to the Governor of the State or Territory in which
said college or school is established, and a printed
copy of said report shall be sent to each school or de-
partment of mines herein provided for, and to the
Secretary of the Interior. Said report shall contain
a statement of all experiments and work of a practi-
cal and scientific nature conducted during the pre-
ceding year, which may be considered of special
value to the mining and metallurgical industries, to-
gether with the condition and progress of such school
or department, including general information as to
the number of its professors and students, its courses
and methods of instruction, its library and general
equipment. Bulletins or supplementary reports shall
be published by said schools or departments from
time to time on subjects of importance to the mining
community or to the interests of any parti ular
branch of mining industry or mining districts."
The bill is in direct line with existing requirements;
the small amount embraced in the appropriation
should be regarded as an investment that would
make direct return of an exceedingly profitable
nature.
It will take some effort, however, to direct public
opinion to the manifest value of the proposition, and
from our standpoint the success of the bill does not
seem of present promise. The measure will be op-
posed by those who see in it a menace to their indi-
vidual interests, and such opposition will be more
active than the. sleepy indifference of the public to
anything of that nature.
There is a growing demand for mica consequent
upon its use for electrical insulation, and among
manufacturers of electrical machinery mica in such
small sheets as were formerly unsalable now finds
purchasers. Even scrap mica is now being utilized
for lubricants. Last year the United States pro-
duced 108,570 pounds sheet mica, valued at $70,587,
and 1505 tons scrap mica, worth $30,878. This was
considerable of a decrease as compared with former
years, caused by increased imports, which last year
amounted to 256,228 pounds, valued at $1,616,397.
During the year 1899 the total importation of mica
manufactured was 1,709,839 pounds. The importa-
tion of mica is on the increase, and domestic produc-
tion is on the decrease.

"Concentrates" knows of no place in this country
where tin ore is mined or smelted.
Last year there was a total production of zinc oxide
directly from the oro in the United States of 39,661)

WATER in freezing tends to purify itself, the tendency-

The fluorspar mined near Prescott, Ariz., runs about
35 cents per ton silver, but is used as a flux by the San

At the beginning of the Boer war there were about
13,000 white men employed in mining in the Rand, S. A.,

Under certain conditions and in conformity with cer-

"Ore in sioht " is indeterminate. Where three
sides of the ore body are visible, it is possible to give
measurements of quantity and estimates of values.
There have been poets among miners. The great
German poet Goethe was a miner, and for many years
had charge of all the miners in the duchy of Weimar.
One indication of the cessation of hostilities in South
Africa is the fact that cipher telegrams may again be
sent, they being no longer interdicted, and a code book is
once more of some value.
A GOOD anti-friction metal is made of Banca tin 89%,
antimony 7.4%, Lake copper 3.6%. The Government
bought 20,000 pounds of that alloy last week, delivered
at Washington, D. C., at 27J cents per pound.
Financiers figure that at present there are about
12,500 tons of gold in the world, of which about 7200 tons
is monetary gold stock, nearly six times as much gold
being in circulation as there was 100 years ago.
The " electric explosion " noted in the San Francisco
daily papers as occurring in a building corner Sansome
and California streets, was an explosion of gas. Elec-
tricity does some queer things, but never "explodes."
A MAN can not hold a quartz location "by building a
reservoir and spending $100 worth of work on the reser-
voir, but doing no other kind of work on the quartz
claim, "even though the reservoir be situated on the
claim.
Eight persons can locate, jointly, 160 acres placer
claim; for each twenty acres the equivalent of $500 in
work or improvement must be done before the locators
can secure patent. One discovery on the whole tract is
sufficient.
Cryolite is extremely fusible, melting in a candle
flame; it is used in the manufacture of aluminum and
sodium. It is found in small quantities in Colorado. Its
chief source of supply is from Greenland, where it is
found in large deposits.
Squared timbers 12 to 18 inches are frequently used
for mine timbering, and in the Coeur d'Alenes are thor-
oughly coated with lime when put in, which, adding to
the light of the station, aids in preserving the timber,
and as a slight fire preventive.
IF an inventor' forgets or abandons his invention after
a reduction to practice in private, and before a public
use, his competitor may claim the patent. If he forgets
or abandons it after a public use, his competitor can take
no patent, but the forfeiture will inure to the benefit of
the public.
The watt is the unit by which electrical energy is
measured. It is calculated as being equal to the current
of one ampere flowing at a pressure of one volt, i. e., a
current of ten amperes with a pressure of 100 volts rep-
resents 1000 watts. A horse power is understood to be
the equivalent of 746 watts.
IN figuring on electrical transmission and thus utiliz-
ing water power, where the question comes up of relative
cost, it is to be remembered that in the case of building
a dam and construction and maintenance of a reservoir,
is involved a fixed investment, and one that is not ordi-
narily susceptible of being turned into money.
It is now common in chlorination work to neutralize
the free chlorine in the leach liquors by ferrous sulphate
instead of by use of S02, about seventy-five pounds of
the sulphate being added to thirty tons of the solution.
The ferrous sulphate is obtained as a by-product from
the generation of the hydrogen sulphide there used as a
precipitant for the gold.
There is nothing electric about "galvanized" wire.
The process of manufacture is purely mechanical
throughout. The wire, after annealing, is cleaned in di-
lute hydrochloric acid, then run through a trough con-
taining a slightly stronger bath of the same acid, into
molten zinc, then rewound, the superfluous zinc being
wiped off as the wire leaves the bath, by means of as-
bestos or sand.
Molybdenite, concentrated, is worth about $200 per
ton. Molybdenum is quoted at $1.45 per pound in New
York City. It is not used on the Pacific coast. The
Illinois Steel Co., Chicago, or the Bethlehem Steel Co.,
Bethlehem, Pa., could furnish information as to probable
purchase of either the molybdenum sulphide or the
metal itself. It is commercially used as a deoxidizer in
steel manufacture.
For shingling 4-penny cut nails are considered superior
to 3-penny wire nails. The latter are the same size all
through, and they rust out near the head by continual
exposure, while the former has twice the amount of
material near the head than at the point, and will last
much longer. Iron nails are considered preferable to
those made of steel.
A change in the output of a mine is not unusual. In
the Comstock, Nevada, the ore was almost exclusively
silver bearing at first, but depth yielded bullion that was
54% silver and 46% gold; the Anaconda was originally a
silver mine, but with depth changed to copper; in many
cases in Colorado silver-lead ore has changed with depth
in gold ore assaying in some cases twelve ounces to the
ton.
It is against the business policy of this paper to take
machinery or supplies of any kind in payment for ad-
vertisements therein. It would be manifestly unfair to
our advertising patrons to do so, because the only use
the paper would have for such material would be to sell
it, and that would immediately put tho paper in the po-
sition of being a competitor of the men who advertise
herein; hence such proffers are invariably declined.
Any company can change its principal place of busi-
ness by holding a special stockholders' meeting to amend
its by-laws for that purpose. The principal office must
be in the State in which the company is incorporated,
but they can have as many other offices as the board of
directors deem advisable. The company can do business
in any county in this State by filing a certified copy of
their articles of incorporation with the county recorder
where they desire to operate.
AN assay from a specimen piece of ore, however ac-
curate, is no index of the value of the ore body from
which it came. The assayer can only give the value of
the sample furnished him. To afford any fair idea of
the value of the mine the sample must be of the average
of the ore and not a picked specimen; and a " mill run "
of ten tons can, with a little further effort, be simply an
aggregate of selected ore much richer than the average
ore from the mine would furnish.
Within the last decade sulphuric acid has been com-
mercially produced by passing a mixture of air and sul-
phur dioxide over finely divided platinum heated to 400°
C. Sulphur trioxide is thus formed as a vapor, which is
dissolved in water, thereby forming sulphuric acid.
Special precautions are taken to keep the heat below
800° O, at which temperature the sulphur trioxide is de-
composed into sulphur dioxide and oxygen. On account
of its simplicity and cheapness, this method seems likely
to replace the older and more cumbersome process.
Readers of this paper doubtless notice that through
the years appear fine engravings of mining scenes from
every part of the earth where mining is carried on. For
the photographs from which these engravings are made
we are largely indebted to the thoughtful kindness of so
many of our friends who, traveling about, send pictures
of note from where they are sojourning for a season. We
would be pleased to receive photographs of mining
scenes for such reproduction from our readers every-
where, and would gladly give due credit for such graphic
remembrance.
Work on the Sutro, Nevada, tunnel began October
19, 1869. Connection was made with the Savage shaft
July 8, 1878. The distance from the mouth of the tun-
nel to the Comstock vein is 20,016 feet. The tunnel was
bored by "day's work," $5 per day being the lowest
wages paid workmen. The " system or plan by which
the owners were remunerated for the expense " never
fully materialized. The plan was to secure sufficient in
royalty for the use of the tunnel by Comstock mine
owners to produce profit. But by the time the tunnel
reached the Comstock the bonanza days were about over.
The two names muscovite and sericite practically sig'
nify the same mineral, though sericite is employed for
the fine-grained or fibrous and tufted modifications re-
sulting from the replacement of other minerals. Sericite
is probably the most universal and abundant of all min-
erals forming in altered rocks near fissures. Only a few
classes of ore deposits— namely, those in limestone and
those in recent volcanic rocks, involving propylitic alter-
ation— are comparatively free from it. A vast propor-
tion of so-called "talc," "clay" and "kaolin" is really
sericite. Sericite forms from quartz in many rocks,
though this action is less intense than in the case of the
silicates.
As to the question, " What is steel ? " " All metal
produced from iron or its ores, which is cast and malle-
able, of whatever description or form, without regard to
the percentage of carbon contained therein, whether
produced by cementation or converted, cast or made
from iron or its ores, by the crucible, Bessemer, Clapp-
Griffiths, pneumatic, Thomas Gilchrist, basic, Siemens-
Martin or open-hearth process, or by the equivalent of
either, or by a combination of two or more of the pro-
cesses, or their equivalents, or by any fusion or other
process which produces from iron or its ores a metal
either granular or fibrous in structure, which is cast and
malleable, excepting what is known as malleable iron
castings, shall he classed and denominated as steel."
Steel is an artificial compound of pure iron and carbon.
The iron gives the strength and the amount of carbon
regulates the hardness, toughness and ductility of the
compound, so that the compound is kept low if a soft
and ductile metal is desired for use in boilerplates, hoops,
sheets or wire. It is carried somewhat higher for rails
and decidedly higher for tool steel, cutlery and drills.
IN any given conditions minerals tend to assume the
forms most stable under those conditions. Since the con-
ditions prevailing during vein formation are very differ-
ent from those prevailing afterwards, it may be inferred
that the products of the first process might easily be
changed. Such is, indeed, the case, as one finds many
altered rocks which have evidently undergone more
than one change. Especially near the surface, under the
influence of oxidizing waters, the minerals formed in
the rocks along veins are apt to suffer great changes.
Examples are frequent, showing that the minerals which
filled the open spaces along a vein have been completely
dissolved and partly or wholly replaced by others. This
is particularly true of fillings of calcite or baryte. In-
stances are known in which large masses of these min-
erals have been completely dissolved and replaced by
quartz, as in the case of those of the De Lamar mine,
Owyhee county, Idaho.
A plant to work the Hoepfner wet process for the
extraction of copper at Papenburg, Germany, has a daily
capacity of a metric ton of refined copper. The ore is
first crushed in ball mills and leached with cupric chlo-
ride solutions. The solution dissolves copper, lead, nickel
and silver, the cupric salt being reduced to the cuprous
state. After purification and being freed from silver,
the solution is allowed to flow to a compartment with
carbon anodes and copper cathodes. Chlorine is liber-
ated at the anodes, regenerating the cupric solution,
which is returned to a fresh charge of ore. It is claimed
that 91% of the contained copper was obtained after four
hours' treatment of Rio Tinto ore containing 3.37% cop-
per, and only 3% of the iron content dissolved. By lon-
ger contact 98.5% of the copper was extracted, with only
4% of the iron taken up. It is claimed, moreover, that 1
H. P. in twenty-four hours will produce fifty-four kilo-
grams of copper, as against fifteen kilograms by the sul-
phate process.
The total bullion product of the Con. Cal. & Va. mine,
on the Comstock, Nevada, up to Oct. 1, 1896, according
to the official statement of President Fish, was as fol-
lows: Gold $61,780,474.86, silver $69,856,832.96, total
$131,637,307.82. Dividends: California $31,320,000, Con-
solidated Virginia $42,930,000, Con. Cal. & Va. $3,898,000,
total $78,148,000. The Savage-Norcross-Chollar joint
shaft, known as the Combination, is the deepest vertical
shaft on the lode, having a depth of 3375 feet from the
collar of the shaft to the bottom of the sump. This
shaft has five compartments, requiring an excavation 40
feet in length by 10 feet in breadth to admit of timber-
ing. The lowest workings in the Sierra Nevada, Union
and Mexican joint winze reached a depth of 3200 feet
below the surface. The Yellow Jacket new shaft had a
depth of nearly 3000 feet, the Forman 2800. The Crown
Point and Belcher lowest workings were at a depth of
nearly 3000 feet below the surface. The Best & Belcher
and Gould & Curry joint shaft, known as the OsHston,
had a depth of 2800 feet.
If two or more own a mining claim in common, each
co-owner, however great or small his share may be, has
a right to go to work anywhere on the claim that he
wishes to, so long as he does not interfere with any of his
co-owners who may have gone to work before him. No
agreement or understanding with his co-owners is neces-
sary. If one (or more) of the co-owners in a claim com-
mences operations on the claim, without any agreement
with the other co-owners, he can take out ore and mar-
ket it and can not be prevented except by process of law.
If the proceeds of the ore exceeds all his expenses of
mining and marketing it, he must divide the net profits
with his co-owners, pro rata to their respective interests
in the claims. If, on the other hand, he fails to realize
enough to pay expenses, he can not hold his co-owners
for any part of the loss. In case he refuses to give an
account of his operations to his co-owners, they can sue
for an accounting, and, if they so desire, can couple with
the suit an action for the ejectment of the co-owner who
is working the mine, and petition for a receiver.
In Souter vs. Maguire (78 Cal., 543), it was held that
where the locator of a mining claim marked the corners
of the end lines, placed a stake or blazed a tree at each
corner of the claim, and in places brushed out the lines,
so that a person could get through, and placed a notice
in the center of the claim defining the boundaries, that
it was sufficient to justify a finding that he had marked
off the boundaries as required by the Act of Congress.
In the absence of State legislation, or local regulation,
what constitutes a sufficient marking is a question to be
determined by the jury according to the circumstances
in each particular case. The Land Department of the
United States (L. O. Regs., par. 15) recommends, and in
many localities the custom prevails of driving stakes,
building rock mounds, or blazing and marking trees, or
brushing out along the end and side lines of the claim,
and, in addition thereto, posting a notice in a conspicu-
ous place on the claim, and sometimes marking the end
lines of the ledge. The law does not require this charac-
ter of marking; but inasmuch as it has been held by the
highest courts to be a sufficient marking, it has been
adopted by miners. Whether the boundaries of a claim
are distinctly marked on the ground is in all cases a
question of fact, and not of law. All that the law re-
quires is that the location must be distinctly marked
on the ground, so that its boundaries can be readily
traced. This requirement is an imperative and indispen-
sable condition precedent of a valid location.

Relative Values of Fuels Used on
the Pacific Coast.
From Determinations Made by Irving C. Allen, M. S.t
University or California.
The question of the relative values of fuels for pro-
ducing heat and for convenience and desirability for
use, in proportion to cost, is one of importance.
In addition to the article published in our issues of
Sept. 15 and 22, on the use of " California Crude
Petroleum as a Fuel," by Ernest H. Denicke, Col-
lege of Mining, University of California, we have the
results of some elaborate and exhaustive tests
of coals and other fuels handled at San Fran-
cisco, which have been made by Irving C. Allen, M. S.,
College of Chemistry, University of California. This
article is taken from a thesis, written by Mr. Allen,
in which he gives at length his method of making
these determinations, both mechanical and chemical,
with descriptions of the apparatus used.
These tests, which include the leading coals
handled at San Francisco, showing their exact com-
parative values for heat producing, and their
chemical analysis, are the results of many months
of careful, painstaking labor made by Mr. Allen
as Assistant State Analyst, under the direction
of Prof. W. B. Rising, Dean of the College
of Chemistry. (Mr. Allen is now Government Chemist
at Manila.)
We wish to call especial attention to his description
and manner of using the Berthelot combustion bomb
and accessories, an elaborate apparatus manufac-
tured in Paris for determining fuel values, which de-
scription we copy in full from his thesis. The value
of the calorie is stated to be " the quantity of heat
required to raise the temperature of one gram of
water through 1° Centrigrade."
The bomb used in these determinations was made
by M. L. Golaz, Paris, and consists essentially of a
cylinder of the best tool steel, 10 cm. external diam-
eter at the base and reduced 8 cm. from the base to
an external diameter of 7 cm. This cylindrical shell
is 1 cm. in thickness and is nickel plated outside and
porcelain lined within, and is of 586 c. c. capacity.
On to this screws a cap with a hexagonal top, made
to tighten with a large wrench, and is made tight with
a lead washer and an iron shoulder. Through the
center of the cap passes a conical-seated screw-
cock of fine nickel, made to admit oxygen. The body
of the bomb is 16 cm. high, with the screwcock pro-
jecting 11 cm. above. Electrical communication is
made with the interior of the bomb by well-insulated
platinum wires passing through the cap. One of
these wires is bent into a ring at its lower end and
supports the small platinum dish containing the sam-
ple. One encjj of a small iron wire, used to ignite the
coal, is wound tightly around each of these wires and
completes the circuit within the bomb.
The calorimeter itself consists of a brass cylinder
or cap 14.5 cm. in diameter and 23 cm. high, and con-
tains 2300 grams of water, into which is immersed
the bomb. This is protected from external thermal
influences by an air jacket 1.5 cm. thick, a water
jacket 7 cm. thick; and over the whole is a felt wrap-
ping 1 cm. thick. The water in the inner cup is
thoroughly stirred by a coiled agitator, worked by a
string in the hands of the observer.
All observations were made at a distance of about
8 feet from the calorimeter, with the aid of a good
telescope, in the following manner: About one gram
of the sample is accurately weighed into the plati-
num cup and the cup placed in the ring of the bind-
ing post. A length of fine iron wire (No. 35) 7 cm.
long, is made to loop under the surface of the sample
in the cup, and each end is wound three times tightly
about one of the binding posts, passing through the
cup of the bomb. If the iron wire be much longer
than 7 cm., beads of burning iron will drop during
the combustion into the cup and fuse holes through
the bottom. If the wire be not firmly wrapped about
the binding posts, the current passing through the
wire may not be sufficient to cause fusion, and the
sample may not be ignited, and this necessitates
opening the bomb and rewrapping the wire — a trou-
blesome operation after the apparatus is set up. To
make the fusion of the wire, an ordinary lighting cir-
cuit enters the laboratory, and from this is shunted
through the bomb a small current of 4.6 amperes and
of about one volt, of just about sufficient strength to
cause fusion of the wire. In this shunt current there
is a spring key, and by snapping this key a spark is
struck, when all connections are properly made. If
there be no spark, there is a faulty connection in the
circuit, and it may be looked for either outside or in-
side the bomb and corrected. This spark is not of
sufficient duration to cause fusion of the iron wire,
and shows before any readings are made that the
apparatus is properly adjusted.
All ragged edges of the lead washer are carefully
cut away, for splinters of lead may cause leaks when
the bomb is charged, and the screw threads are
slightly vaselined, exposing no vaseline inside the
bomb, and the cap screwed on. The bomb is gripped
in a clamp fixed to the table and the cap tightened.

Connection is made with the oxygen cylinders by
means of a strong copper tube and oxygen run in
until the manometer indicates a pressure of 25
atmospheres. (These cylinders are of heavy iron, of
6 liters capacity, and are charged with a pressure of
1100 pounds. When the pressure of any one cylinder
falls below 25 atmospheres, the connections may be
changed to a cylinder of high pressure and the bomb
charged up to 25 atmospheres, thus utilizing the oxy-
gen in the cylinders until the pressure falls as low as
two or three atmospheres.)
The screwcock on the top of the bomb is closed
and the bomb removed and placed in the inner cup of
the calorimeter, into which 2200 grams of water have
been accurately weighed. The thermometer — which
reads to thousandths of a degree Centrigrade — and
stirrer are adjusted and the stirrer run for five min-
utes before any readings are made. After five min-
utes a reading is taken at the end of each minute un-
til a series of five concordant readings are obtained,
and the initial temperature, i. e., the temperature of
the calorimeter bath before the ignition is made,
is ascertained. The shunt circuit is completed
for five seconds and the sample is ignited by the fusion
of the iron wire. After the lapse of about ten seconds
the temperature will rise rapidly for about four min-
utes and while during this time no readings of the
thermometer are possible, the time must be recorded,
and when the temperature begins to fall regularly a
series of readings must be made — one each minute
for from ten to fifteen minutes. The average rate of
cooling or radiation after ignition is ascertained.
Assuming that this radiation represents the cooling
from the instant of ignition — which is not absolutely
true, as the radiation from the calorimeter bath im-
mediately after ignition is necessarily less than when
the temperature of the bath has risen 3° or 4°; the
temperature is calculated at the instant of ignition.
This temperature, corrected for radiation, is the
temperature to which the calorimeter would rise if
subjected to no external thermal influences. As there
were 2200 grams of water in the calorimeter bath,
and the water equivalent "E " of the calorimeter is
ascertained to be 521 calories, the increase of tem-
perature over the initial temperature multiplied by
2721 indicates the calories liberated by the combus-
tion of fuel and iron wire.* Deducting the calories
liberated by the weight of iron wire used, the calories
liberated by the sample of coal is ascertained.
The bomb and calorimeter are illustrated on the front
page. The plate represents the bomb and calori-
meter disconnected ; BC = bomb cylinder ; BK —
bomb cap ; D = combustion dish; B = base for cylin-
der; P = binding posts ; S = stirrer; A = agitator;

* According to Berthelot, 1 gm. of pure iron wire, burning to Fe2

A New Throttle Valve.
The Pendry balanced throttle valve, shown in sec-
tion in the accompanying cut, is considered by the
makers well adapted for use on hoisting engines,
marine engines, steam shovels and on all quick act-
ing engines, as by means of it the full boiler pressure
can be instantly admitted to the cylinders and as in-
stantly shut off. In addition to its quick opening
feature, it is also a perfectly balanced valve, and so
can be easily operated, no matter how great the
steam pressure being used.
Its operation is as follows: The stem A forms two
seats with the main valve B — one at its upper and
one at its lower end. The first slight movement of
the handle will raise the stem A off its upper seat.
The steam passes in through this opening, down
through the body of the valve B in the space around
the stem and into the balancing chamber E through
the openings marked F on the small sectional view of
the valve body to the right. In this way the full
boiler pressure is admitted into the chamber E, bal-
ancing the valve; and, as the same pressure is below
as above it, it is very easily operated. While this
valve is primarily a quick opening one, it can be
opened as slowly and as gradually as a screw stem
valve, and will stay open at any point one may desire
to set it. This feature makes it adapted for use on
all types of steam engines. The question of leakage
can also be prevented in this valve, as it has but one
seat, and this can be ground the same as that of a
globe valve. A circular giving full description may
be had by addressing the manufacturers — The De-
troit Lubricator Co., Detroit, Mich.

Pyritic Smelting in the Black Hills.*
NIMHER IV.— CONCLI i
In the replacing of lime with magnesia, the forma-
tion temperature rises rapidly until one-eighth of
the lime has been replaced with magnesia ; then it
falls until one-fourth has been replaced; then rises
until one-half has been replaced, and suddenly falls
until five-eighths have been replaced, and then rises
rapidly until the whole of the lime is replaced, where
it reaches a formation temperature too high for
metallurgical work.
The curve, after the addition of magnesia, while it
falls at two points rather low, at no time reaches the
line of the basal or normal lime-iron silicate.
That the same or a similar curve would be ob-
tained if a different percentage of silicate were used
— as, for instance, our Deadwood slags — is probable ;
but the use of magnesian limestone for our slags was
preferred to the pure limestone. Nothing like a sci-
entific attempt was ever made to determine the for-
mation point of our slags, hence I can not say that
they were less fusible than they would have been
with all lime and no magnesia. They did seem more
liquid, and certainly less magnesian limestone was re-
quired for the same work. This was due, of course,
to the lower combining weight of magnesia. One
part by weight of silica to form a bi-silicate slag re-
quires 0.93 parts of lime, but only 0.66 parts of mag-
nesia.
Again, the Hofman curves show that the formation
temperature falls when lime is replaced by alumina.
It falls below the line of his basal silicate until as
much as three-fourths of the lime has been replaced
by alumina. The slags, however, were very viscid.
Now, if magnesia raises the formation point above
the normal, and alumina lowers it, the net results
might be, in our slags, not only to cancel each other's
effec_ts,_but to give a more fluid slag, owing to the
multiplication of bases, which in a general way is
known to have that effect.
In pyritic smelting the slags must possess distinct
characteristics — even if accomplished at the sacrifice
of other points. First— They must be of low specific
gravity, owing to the low specific gravity of the
matte, that a perfect separation may be had by
gravity. The high silica, lime, alumina and magne-
sia, and low iron, tend to bring this about. Second —
In order to have time for the matte to settle out
they must not chill it too quickly. It is desirable,
therefore, to form a slag which will remain fluid as
long as possible. The low formation points of the
high silica slags tend, I think, to aid this.
Before the appearance of Prof. Hofman's paper
the peculiarities of slags were known only in a gen-
eral way; and, speaking for myself, I knew more
from the work of Percy and Smith than from any
other sources. Percy did not, however, do more
than to make mixtures and melt them in crucibles
and note the results. In determining what silicates
I could make at Deadwood I simply followed the
Percy-Smith methods ; but by the aid of Prof. Hof-
man's paper it is now possible for the first time to
predict what effects certain elements will have. In
new work that I am doing for a matte smelting plant
at Buena Vista, Colo., and another for Cripple Creek
ores, I have found this paper of great value.

In our slag calculations we saved time by the con-
tinual use of Balling's well-known tables. The prob-
lem in our sort of smelting is Very simple. We deter-
mined by means of the second table how much silica
was fluxed by the iron, lime, etc., contained in the
ores, subtracted it from the total amount to be
fluxed, and then, by means of the first table, sought
how much limestone must be added to take care of
the remaining silica. Of course, a chemist can do all
this without the aid of tables, and, moreover, since

If any one doing this kind of smelting will keep his
slags between 4RO, 3SiO,, and RO, SiOs, his troubles
will be few, provided he has proper bases— i. e., lime
and iron, etc. If there is a trade secret about matte
smelting for gold and silver, it is this only. The Bal-
ling tables will enable the most ignorant to observe
these limits. The "typical" slags of lies, Eilers,
Schneider, Raht, Hahn, Page and Livingston may be
left as guides for the lead smelters, who have need of
them by reason of a widely different problem. To
the matte smelter they are not only useless, but con-
fusing, and, I believe, often the cause of failure.
With the iron matte low in copper, it is immaterial
whether a little more or less iron goes into the slag.
The resulting matte will carry the gold and silver in
any case. The smelter in this line is not concerned
with problems relating to the scorification of copper
and lead.
Refining and Disposition of the Matte. — With
iron matte, or matte very low in copper, there exists
usually no problem, for it can be sold to the lead
smelters. With high percentages of copper in the
matte, however, there is a difficulty. It carries usu-
ally too much gold for the ordinary copper refineries,
and too much copper for the lead refineries.
At one time, about 1892-93, we had a difficulty in
disposing of our matte. We erected a lead furnace,
bought lead ores, and crushed and added the matte
raw to the lead charge. I found that the matte gave
up nearly the whole of its gold to the lead. It still
contained much silver. This matte was very differ-
ent from the " first matte," and for want of a better
name we called it after the Germans, ' ' herd rohstein "
(hearth matte), and added it to the matte smelting
charge, but, owing to its containing lead, this treat-
ment had not much success, as the lead was lost.
The resulting bullion in the lead process — very high
in gold — was sold to the lead smelters. Fearing that
they might decline to buy this, also, we erected one
very large cupel, and two smaller ones, all of the
English type, intending to cupel the bullion and add
the resulting litharge to the lead process. The whole
process was borrowed from pyritic smelting as it is
practiced in Kongsberg and in Russian Siberia, save
that I used an ordinary American lead smelting fur-
nace, and English cupels. The process, except as to
the loss of lead in the matte furnace, was promising,
and, in the favorite language of the patent right man,
"continuous." The "first matte " went into the lead
furnace, the second or hearth matte back into the
matte furnace. The lead bullion went to the cupels,
and the litharge back to the lead furnace. I do not
know how this experiment would have ended, for our
difficulties with the lead smelters were adjusted and
our relations with them ever afterwards remained of
the most pleasant character.
The idea of refining, however, continued with me,
and in connection with Arthur Howe Carpenter I
made many experiments, sometimes original, but
more often after the lines laid down by the old metal-
lurgists, who seemed to have covered, in theory at
least, about everything. The most satisfactory pro-
cess, and the one I should have followed had I re-
mained at the works, was that laid down by Jars (I
think in 1784) and quoted by Percy in the first edi-
tion of his "Metallurgy." Afterwards it was pat-
ented by the Vivians and others, and forms the first
step, at least, of the Argo process. It will be
remembered that our process was mainly for gold,
and that copper matte so high in gold was not de-
sired by electrolytic copper refiners. Any process
that would take out the gold and other " impurities "
would fit it for their process. The first step is the
well known copper-bottom process described for us
by Dr. Pearce in his presidential address. I pro-
posed not to try to separate the silver from the
matte, but to proceed at once to the copper-bottom
process, which I thought might be performed either
by the French " selecteur " method or as is now done
at Argo.
The resulting product — high-grade copper matte —
having given up nearly all of its gold and much of its
silver, could be blown up to blister copper and sold
directly to the refiners. The copper bottoms I gran-
ulated, oxidized and cast back into matte and effected
a second "selecting," similar in all respects to the
first.
This selecting process is not wholly successful un-
less the copper matte is impure, a certain percentage
of lead being necessary. This lead is, of course, con-
centrated in the first bottom or " selecting," so that
this carries a very large percentage of lead. In the
second selecting this is so increased that the result-
ing bottom may be at once cupelled — often requiring
little or no additional lead. In fact, the first bottom
can be directly cupelled, with the addition of lead, if
so desired, the coppery litharge being, as shown by
Samuelson, even more fusible than the purer litharge
of the ordinary methods. In practice six parts of
lead to one of copper give very satisfactory results.
The coppery litharge forms a product which can be
treated by the lead smelter, who has but to add to it
his ore charge — the lead going to the bullion and the
copper to the matte.
It is unnecessary actually to repeat the selecting
process in all its details upon the first bottoms as
above described. Equally good results, with much
less trouble, can be had by simply returning the first
bottoms, or "plates," to a reverberatory furnace,
with additional sulphide material, and running them
over and over until they are sufficiently reduced in
size for final treatment by cupellation with metallic
lead. The resulting coppery litharge is easily re-
duced to metallic lead and matte by treatment in a
small reverberatory or "softening'" furnace, with
galena or iron pyrite. The lead may be used over
and the matte is returned to the ore smelting.
Factors of Safety.
To the Editor: — In the enclosed clipping the state-
ment is incorrect, and might get some engineer or
boiler owner into serious trouble if followed :
In the case of a boiler 72 inches diameter, double-
riveted lap seam, [J-inch rivets spaced 3 inches between
center, thickness of plato ft inch, of 60,000 pounds ten-
sile strength, the safety valve should be set to relieve
the boiler at 130 pounds.
First, the United States factor for safety on steam
boilers is 4^ for punched holes and 3/v for drilled
holes. Philadelphia city law, also the English, French
and Russian laws, require a safety of 5, whereas in
the example given the safety factor under 130 pounds
steam pressure would be 2ft75, or just a little more
than twice the steam pressure carried.
Second, the size of rivets given ([},"), \" holes, is
entirely too small for Ty boiler plate. They should
be \%" rivets driven in V" rivet holes pitched about
2?", centers, to get a fair joint.
The average shearing resistance of good iron
rivets in a lap joint (single shear) is 38,000 pounds
per square inch of section.
Taking the example as given, it would work out
as follows : Boiler 72" diameter, Ty plate, 60,000
pounds T. S., \y rivets, |" rivet holes, 3" pitch.
TVX3"X60,000 T. S. =101,250= solid plate. 3"— .75
=2.25X60,000 -- 75,537 net section. (Rivet hole=3")
.75 X .75 X .7854 = 4417°" X 38,000 = 16,784 pounds
shearing resistance of one rivet. Two rivets = 16,784
X2=33,568 pounds. The rivets are the weakest ;
therefore the strength of the rivets divided by the
strength of the solid plate= 33,568-^ 101, 280=33,^%
as the efficiency, or percentage of the joint to the
strength of the solid plate. (It should be 70%.)
Then, . 5625 X 60,000 T. S.^36"(radius)=937 J pounds
as the bursting pressure of the solid plate. Then,
937T6ffX33T'TT=310 pounds as the bursting pressure of
the seam. Then, 310H-4r% as the safety factor re-
quired by United States law for punched holes =73rsff
pounds as the safe working pressure ; if the rivet
holes were drilled, then 310-5-3^r=88y5 pounds as the
safe working pressure.
If the joint had been properly proportioned, then
the safe pressure for drilled holes, according to the
United States law, would be 937.5X70%= 686 as the
bursting pressure of the seam ; then, 686H-3fs=193
pounds as the safe working pressure.

Witte Gas and Gasoline Hoist.
The latest improved Witte gas and gasoline hoist,
illustrated on the front page, is designed to use any
grade of gas or liquid fuel capable of generating heat,
but fuel which leaves no sediment. The hoister bed
has bolted to it the engine and all the working parts,
levers included, only one foundation being necessary.
A loose drum is bushed with phosphor bronze ; bear-
ings have large spring grease cups to properly lubri-
cate them. The gears, being on the outside of the
hoister bed, can be changed to any ratio capable of
speed required for different classes of work. The
hoist is so constructed that different size drums may
be furnished for the different classes of work. The
hand levers are so arranged that the tripping device
may operate with the palm of the hand or fingers by
changing a pin. There are six key seats for the ad-
justment of the power thrust screw, and the speeder
attachment, being on the inner side of the flywheel,
permits easy starting. The engine is dowel-pinned
onto the hoister bed to prevent movement. The two
flywheels of the engine are close up to their main
bearings, to prevent springing of the crank shaft.
Full instructions and drawings accompany each ma-
chine, to enable any one to set it up. The Witte
Iron Works, Kansas City, Mo., furnish a guarantee
for five years, covering any defective workmanship
or material. . They are represented in San Francisco '

Use of Hot Blast in Smelting.
To the Editor: — As to the use of the hot blast in
smelting, one of the first and most important items
to consider when heating the air blast is that it in
no way interferes with the regular working of the
blower, as the blast passes through the blower cold
as in the ordinary way, so that all calculations as to
the amount of blast required and used can be based
on the regular volume handled by the blower, the
same as when using cold blast, and it is customary to
calculate the amount of blast furnished by the tables
sent out by the manufacturers of the different blow-
ers. In this way the amount of free oxygen sent
into the blast furnace, whether heated or cold, can
be calculated provided there would be no obstruction
to the free passage of the air through the heating
apparatus. It is therefore necessary that the area
of the heating box shall be sufficiently larger than
the inlet where the cold blast enters that no back
pressure is created, and the outlet of this heating
box shall be made with nearly double the capacity of
the inlet on account of the increased volume of blast
occasioned by the heating process.
The first heat required is for heating the air blast
up to the temperature when the oxygen will combine
with either the carbon of the coke or the sulphur
contained in pyrites; then the necessary heat for
melting ores and fluxes so that they will combine to
form the proper silicates for fluid and clean slag is
produced by the oxidizing of the fuel added to the
charge by the free oxygen contained in the blast. If
a cold blast is used, all the free oxygen going in with
it is required to oxidize the extra fuel required to
heat the blast, thus leaving none for the sulphur. If
more cold blast is used, so as to get still more free
oxygen, it drives the heat still farther away from
the tuyer openings into the furnace and reduces the
smelting area of the furnace in that proportion,
driving the heat higher up in the furnace, burning
the fuel and smelting the ore so near the top of the
furnace that any metals volatilized have no chance
to get caught by filtering up through the cool layers
of ore charges on the top, and keeps the fuel burning
so high above the tuyers that it leaves very little for
the blast to encounter as it enters unless a very
large quantity has been used.
When the cold blast enters the furnace from the
tuyer openings, and encounters the hot material
without fuel mixed with it to generate the heat, a
crusted furnace soon becomes a consequence starting
at the tuyer nozzle and reducing the capacity of the
furnace until it closes it. This is the result when
either too much cold blast is used or too little fuel is
used with the cold blast. By the use of the hot blast
this trouble is greatly decreased, and the hotter the
blast is the better it is, up to a point where all the
remaining heat necessary for smelting can be pro-
duced by the combination of the oxygen in the blast
with easily oxidized elements in the ore, such as sul-
phur, arsenic, etc., etc. When these elements are
not in sufficient quantity to produce by oxidation the
balance of the heat without making too high a concen-
tration, i. e., not having enough sulphur to make
matte for the regular clean working of the furnace,
then sufficient fuel should be used in order to save
the necessary sulphur for making a proper grade of
matte, so that with a hot blast, a cool
top, and careful feeding, a more uniform
grade of matte is made than has ever
been possible to make by the use of the
cold blast. At the same time there is
less loss of precious metals by volatiliza-
tion.
The advantages of a hot blast over a
cold blast are in the improved chemical
conditions, economy of fuel, and- the
greater capacity of the furnace. Where
the blast is heated without any expense,
every degree of heat so obtained is a
saving of that percentage of coke
needed for fuel in the working of the
furnace. As a matter of fact, the
saving goes beyond that point because
of the fact that the cold blast chills the
charge at the point of contact in the
furnace from each one of the tuyers,
thus reducing the activity of the coke
furnished and imposing an increased
demand on its utility.
This chilling action reduces the capac-
of the furnace in proportion to the area oc-
cupied by the chilled portions, and as near the
nozzle of each tuyer will be found a large surface
of the charge chilled below the fusing point by
the action of the cold blast, which by the use of
the hot blast would be kept active, this propor-
tion cuts a material figure, so that the use of the
hot blast in that direction alone is a decided ad-
vantage. As a matter of fact, it has been found in
the practical working of furnaces on a large scale
that it is advantageous to heat the blast by separate
ovens running at a heavy expense for fuel where the
expense for fuel in operating the ovens for heating
the air was more than double the saving of the fuel
in the furnace charge. It was found that the in-
creased capacity of the furnace and the improved
chemical conditions which result in bringing about a
more thorough fusion of the ore more than compen-
sate for the extra cost of the fuel to heat the air.
This fact having been demonstrated on a large scale
by successful smelting companies, one can see how
much advantage it will be in the cost of operating
any furnace where the air can be heated automatic-
ally without any cost; and, realizing the field for the
improvement in that direction, several inventions
have been brought out to accomplish that end. Most
of those I have seen utilized the heat escaping
from the fumes of the furnace by means of coils of
pipe at some distance above the feed floor of the
furnace. Where a furnace is properly fed and prop-
erly operated so as to prevent volatilization of the
precious metals, there should be very little heat
above the feed floor, so that to utilize the invention
it is necessary to keep a strong blast running
through the entire charge of the furnace, igniting
the free atoms of sulphur and the coke on the top of
the charge, thus causing a heavy loss by volatiliza-
tion where the ore contains any tellurides, lead or
other volatile substances, and thus destroying a
great portion of the fuel heat before the charge
reaches the oxidizing portion of the furnace. In
other cases, attempts have been made to use the
waste heat escaping from the slag, but in doing so
they have been taken in such a way that the fumes
from the slag were driven back into the furnace
again; thus furnishing an impure blast with a great
portion of the free oxygen already removed. The
object of my researches has been to secure a hot
blast which would furnish the air heated to a suf-
ficient degree of heat to prevent chilling, at the same
time increasing the capacity of the furnace and mini-
mizing the use of fuel, and to accomplish this without
any additional cost for operation. This I have been
able to do by what is known as the Bretherton hot
blast apparatus, and in constructing this apparatus
I have kept in mind the principal features required
for its successful operation, doing away with the
back pressure on the blower so that the volume of
air would not be minimized, taking the heat from the
escaping heat of the hot slag by building an oven
around the fore-hearth, the oven having flues passing
through it for the escaping fumes of the slag, similar
to the flues of a boiler, and have augmented the heat
acquired in that manner somewhat by using a set of
air jackets above the water jackets around the fur-
nace, the air having a continuous passage from blow-
er to tuyers. In this way I have been able to keep the
top of the furnace cool so as to prevent volatilization.

Oil and Gas Yielding Formations of
California.
NUMBER III.
The following is a continuation of the advance
sheets of the official report on the oil formations of
California, written by W. H. Watts, and shortly to
be issued by the State :
The asphaltum deposits at Asphalto are found un-
der two conditions : (1) as superficial deposits of im-
pure asphaltum, and (2) as veins of asphaltum in the
Middle Miocene formations. The superficial deposits
of asphaltum have been formed by exudations of
heavy oil. They originally covered a good many acres
and were from 1 foot to 12 feet thick. This asphal-
tum varies greatly in quality. Some of it is brown-
ish in color and resembles ironite. It is frequently
dry and powdery and more or less mixed with earth.
The best asphaltum in these superficial beds lies near
the surface. In some places it forms a stratum
varying in thickness from a few inches to 2 feet or
more. This stratum consists principally of a dull
black, compact asphaltum, but some of it possesses a
pitch-like luster, and here and there it is rendered
viscous by fluid petroleum. Beneath the upper stra-
tum the asphaltum is frequently impure and rotten
and interbedded with drift. Attempts to mine and
refine this asphaltum have proved unprofitable.
The principal asphaltum mines are li miles south-
east of McKittrick. In these mines the asphaltum
occurs as irregular veins and intrusive masses in the
Middle Miocene rocks. These veins are from a few
inches to 5 feet or more in thickness. In one of the
workings that the writer examined in 1894 the foot
wall is light-colored clay and the hanging wall soft
sandstone.
In a cut made by miners who were prospecting for
petroleum in the N.E. i of S. 34, T. 30 S., R. 22 E.,
M.D.M., several strata of impure asphaltum 1 inch
to 1 foot in thickness were cut through. The asphal-
tum was found to be interbedded with thin strata of
light-colored clay, sand and pebbles. One of the up-
permost strata, which is composed of dark-colored
sand, is fossiliferous and contains fresh water shells.
In the Coalinga district oil mining has been carried
on in two fields, in the Oil City field, which lies to the
north of the north fork of Los Gatos creek, and in
the Alcalde field, which lies between Alcalde creek
and the north fork of Los Gatos creek. The most
important of these fields is the Oil City field, about 9
miles north of the Coalinga railroad depot, on the
Southern Pacific Railroad. The lowermost forma-
tion consists of hard sandstone containing numerous
concretions. This sandstone is overlaid by dark-
colored shales and sandstone containing Eocene fos-
sils. Some of the strata of sandstone interbedded
with dark-colored shales yield an oil of low specific
gravity, and have proved very productive. The
shales and concretionary sandstone on which they
rest are of Eocene (Tejon) age. Resting nonconform-
ably on the Eocene rocks is a light-colored siliceous
shale, hereinbefore mentioned as belonging to the
Lower Neocene series. Seepages of heavy, tar-like
oil issue from this shale, and in some places form
beds of asphaltum. In some of the wells in this vicin-
ity an oil of 18° B., apparently from oil sand in this
formation, has been obtained. The light-colored
shale is very much contorted and the exposed rocks
for the most part stand at a greater angle than do
the underlying or overlying rocks. Resting noncon-
formably on the light-colored shales is a series of
sandstone and shales — sandstone predominating —
which contains numerous fossils and represents the
Middle Neocene formation. In most places it dips to
the east of south at an angle of less than 25°. In this
formation immediately overlying the siliceous shales
are strata of oil sand, beds of gypsum, which at one
time were mined, and diatomaceous rocks impreg-
nated with petroleum, the last named resembling the
diatomaceous rocks seen at McKittrick, in Kern
county. The upper portion of the Middle Neocene
formations in this locality is characterized by a soft
bluish sandstone and fine conglomerate containing
fossils of the Middle Neocene age. The soft bluish
sandstone dips east of north at an angle of 10° to 15°.

An Explosion of Scientific Interest.
A singular though not unprecedented accident took
place at the Mammoth mine, in Utah, recently, illus-
trating applied thermo-dynamics in an interesting
but fatal manner, causing the death of one and the
severe injury of another of the engineers of the mine,
says Prof. R: H. Thurston in Science. The cylinder
of an air compressor exploded while in operation in
regular work, and with such violence as gave evi-
dence of more than the action of the normal air pres-
sure in its production. The back cylinder head and
the cylinder itself were shattered. The violence of
the explosion was terrific. The two men were
thrown across the room and badly mangled and one
instantly killed. Fragments of metal and flesh were
found outside the building and a long distance away.
The air pressure, at delivery from the compressor,
was but eighty pounds per square inch. The cause
of the explosion is presumed io have been the com-
pression of the vapors of petroleum given off by oil
used for lubrication in too large quantity and of too
light a quality. Mingled with air in the right pro-
portion for combustion, the mixture of air and vapor
was heated by thermo-dynamic action of compression,
approximately adiabatic up to the temperature of
ignition, and the explosion followed. This action is
precisely that relied upon in the Diesel gas engine,
recently attracting so much attention, for the igni-
tion of its charge independently of gas torch or elec-
tric spark. The phenomenon has long been known
to the engineering profession, although instances of
this kind of accident are rare. The use of effective
methods of cooling the compressor cylinder and the
employment of lubricating oils of high flashing point
constitute the preventives.
Steel Head Gear at Cripple Creek, Colo.
The second steel gallows-frame to be put up in
Cripple Creek district has just been completed at
the Elkton mine. It was furnished through the Hen-
ing 14,617 carats, the second 14,666 carats, and the
third 14,860 carats, the average being 14,713 carats.
According to these measurements 1,000,000 carats
of diamonds of average size would make :
Cu. inches. Cu. feet. Cu. meters.
First 5,131 2.97 0.0841
Second 5,114 2.96 0.0838 »
Third 5,045 2.96 0.0827
Average 5,097 , 2.96 0.0835
Conversely, taking the average, a cubic foot of dia-
monds would weigh 336,700 carats, and a cubic meter
11,976,000 carats. Assuming them to run about the
De Beers average, a cubic foot would be worth about
$2,215,500 and a cubic meter, $78,802,000.
During the eleven years ending June 30, 1899, the
mines of the De Beers Co. produced, in round figures,
25,098,000 loads of "blue ground" — the diamond-
yielding ground — averaging 16 cubic feet each. This
is equivalent to 18,851,000 metric tons. The diamonds
saved from the blue ground were 24,476,000 carats,
including all sizes, and the amount realized for the
stones was $161,152,303. This is an average return

drie & Bolthoff Manufacturing & Supply Co. of Den-
ver. The frame stands 55 feet from the collar of the
shaft to the sheaves. The upright pieces are of
lighter weight than is usually seen ; but the back
braces, extending from the sheaves toward the hoist-
ing engine, are unusually heavy, as in them greater
strength it required. These and the side braces, as
well as the uprights, are anchored in solid piers of
rock and concrete. The two sheaves are each 6 feet
diameter, grooved for flat cable rope. The hoisting
engine, a first-motion duplex, which has already been
described, is ready for business. Two double-decked
cages will be operated in the three-compartment,
800-foot shaft, the cage guides being 4x6 inches in
size. In this shaft was performed the difficult work
of cutting out a third compartment from the 400-foot
level to the surface after the shaft had been made
three compartment from the 400 to the 800-foot
level. Supt. Camps expresses satisfaction at being
through with the job. The next improvement at this
shaft will be to put in electric bell and station sig-
nals.
The waste is taken out on the lower floor, while all
cars of ore are delivered at the top floor, 25 feet
above the collar of the shaft, and taken thence to the
ore bins. The latter are eight in number, each 12x30
feet in size. The ore building, 30x100 feet, is sup-
ported by a heavy retaining wall, and it is believed it
will not settle. The ore bins and chutes are all steel-
lined. In dumping the ore at the top floor it falls
upon heavy grizzlies, below each of which is a coarse
screen, by means of which the ore is partially graded.
The Elkton, Tornado, Raven and Thompson, all the
property of the Elkton Con. M. Co., will from now on
hoist about 1200 to 1400 tons per month.

of $6.58 per carat. The average recovery was 1.3
carats per metric ton, and; the average yield was
$8.55 per ton of blue ground.
The blue ground extracted' during the eleven years
would make a cube with sides 740 feet or 226 meters
long, while the diamonds recovered would be repre-
sented by a cube with sides 50 inches, or 1.27 meters,
long. The ratio in size of the diamond cube to the
blue ground from which it was taken would be about
1:178 in the length of one side of the cubes, or
1:6,000,000 in total bulk.
Uses of Vanadium.
Some Diamond Figures.
Not every one has the facilities for measuring and
weighing a cubic foot — or even a cubic inch — of dia-
monds. The figures given below, which were fur-
nished by an official of the De Beers Consolidated
Co., will have much curious interest. The first meas-
urement taken was of diamonds sufficient to fill a
space of 75 cubic inches, the time being July of the
present year. The diamonds were what a coal oper-
ator would call " run-of-mine " — that is, they were of
all sizes, mixed together just as received from the
works where they were separated from the blue
ground matrix, but had been cleared by boiling in
acid. Three measurements were made, the first giv-
Vanadium is used in the manufacture of aniline
black, which is formed when vanadic acid or a vana-
date is heated with aniline chloride, with reduction to
V2 04. The latter oxide may again be made active
by oxidation with potassium chlorate, so that the re-
action may be often repeated without any fresh addi-
tion of vanadium. This method is useful for staining
wood black, as well as in producing an indelible black
writing ink. When applied to pottery and fired at a,
high red heat, the oxides give a fine gold color with a|
greenish tinge.
Alloys of vanadium and other metals have been ob-;
tained in considerable variety by first using alumi-
num. A cast bar of 1% vanadium had a tensile
strength of 11 tons, an elongation of 7%; aluminum!
bronze, with 8 parts aluminum and 1 part vanadium,
gave 45 tons tensile strength and 12i-% elongation. !
Ordinary malleable iron of about 24A tons tenacity;
and 19% elongation was changed by the addition of
.5% vanadium to 39 tons and 12% elongation in the;
forged bar and 33.7 tons and 32% elongation an-;
nealed. This has called attention to the remarkable;
malleability and ductility of the alloy. A mild steel
of 30 tons tenacity and 17% elongation, with 1%;
vanadium, gave 61 tons tenacity and 14% elongation,1
and, when annealed, 45 tons and 20%; and, although1
very soft when annealed, these alloys become very;
hard by tempering.
At present there are no steel manufacturers using
the oxide in quantity, as the demand for vanadic acid;
as a mordant in dyeing takes the entire supply from
the slags of the Creusot Steel Works in France —
165,000 pounds per annum. A large supply should
admit of the use of vanadium in the manufacture of
steel for armor plate, forgings for ordnance and
naval machinery, projectiles, tools, rolls,, calendars,
etc., and various bronzes.

(Special Correspondence). — The Arno
G. M. Co., of which John Sharpe is presi-
dent and manager, Sol Camp vice-presi-
dent, E. W. Sebben secretary and treas-
urer, was organized to operate on a group
of about ten acres of mineral ground un-
derlying the town of Anaconda, Cripple
Creek district. In the title by which the
lots of this town were transferred to lot
owners the mineral rights were not re-
served. Within the last few months Mr.
Sebben, promoter of the Arno Co., quietly
purchased the mineral rights from the
numerous lot owners, securing surface
title as well to eight lots in one locality,
with the result that the portion of the
mineral ground lying between the Ana-
conda and Mary McKinney groups is
grouped in one compact ownership, a
twenty-year lease from the town having
been secured for the mineral rights under
the streets and alleys. A steam hoist has
been installed on the surface holding of
the company and an 85-foot shaft sunk,
from the bottom of which a crosscut is
being run toward the Anaconda, by which
it is expected to open one or two well-
known leads. The project is attracting
much favorable attention. Wa'scott.
Cripple Creek, Nov. 26.
(Special Correspondence). — The Work is
a large group of mines mostly on Raven
and partly on Gold hill. The Work Co.
is conducting operations on the major
portion of the Poorman claim, the rest of
the group being in the hands of lessees.
Besides the lease of the Woods Invest-
ment Co. on the Morning Glory shaft and
contiguous ground, there are six other
leases, including the May Queen, Poor-
man, Pelland, Whitford, Regan and Carl-
son, the total tonnage from all amounting
to considerable, the grade of ore being un-
usually high. The Woods Co. spent
nearly $100,000 for equipment and im-
provements on their lease, the shaft
through which they work being 700 feet
deep, with crosscuts to the Jack Pot vein
at the 550 and 700-foot levels. Other les-
sees have also spent money freely for im-
provements. All the leases referred to
expire Sept. 15, 1902, thus giving the les-
sees nearly two years yet to operate. At
the expiration of that time the company
expects to assume charge of operations.
The group carries several distinct veins,
there being four veins on the Pelland lease
and five on the Whitford. The ore gen-
erally has run from one ounce to twenty-
five ounces, the maximum value of ship-
ments made, however, being 158 ounces
gold and 94 ounces silver per ton. From
one of the Gold hill shafts a connection is
being made with the Ophelia tunnel,
which at that point cuts Work ground
435 feet below the surface. Wascott.
Anaconda, Nov. 28.

braces, which extend from the top toward
the hoisting engine, are double, made of
10xl4-inch pieces, the upright pieces being
14x14 inches. This construction has been
in charge of J. W. Wade, who has di-
rected most of the timbering in the Port-
land mine within the past two or three
years.
At this same shaft No. 2 a new first mo-
tion hoist has been installed, as well as a
battery of water tube boilers of 1000 H. P.
capacity. The installation of a forty-drill
compressor for No. 2 is also planned.

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co.'s Scien-
tific Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Reproducing Type or the Like.—
No. 662,573. Nov. 27, 1900. W. H. B.
Miller, Oakland, Cal. This invention re-
lates to a means for reproducing metal
type, both face and body, from any cor-
responding type and at a single operation
without the use of a pattern or need for
finishing processes. It consists of a mold-
box having a movable side between which
and the fixed side of the box the type may
be fitted, spacing blocks adjustable in the
channel thus formed to fit upon each side
of the type, a bottom formed of enameled
surface blotting paper, in which an im-
pression of the type face may be made by
a blow or pressure, a cap fitting the top
of said mold having an opening, a melting
pot and guides therefor and a gate mov-
able under the opening and means for
opening said gate in unison with its ad-
justment to the molding-box.
Process of Producing Photo-
graphic Mounts.— No. 662,579. Nov.
27, 1900. P. J. Stuparich, San Francisco,
Cal. The object of this invention is to
produce variously shaded card mounts for
photographs by proper blending of suit-
able inks upon the printing plate, and so
mounting the plate and the cards which
are to be printed as to properly apply the
shade at a single impression. It consists
in removing the center from the printing
plate and applying a shaded ink to the
remaining portion of the plate to form a
deepening tint from one side or angle to
the other and bounding an uncolored
center, finally impressing the plate upon a
card placed to receive the impression.
Hook And Eye.— No. 662,667. Nov.
27, 1900. Nevada McMahon, San Fran-
cisco, Cal. This invention relates to hooks
and eyes for clothing. It consists of a
hook formed by bending wires substan-
tially as shown to form a bight which
comprises the hook, divergent portions of
said wire upon each side and above the
level of the hook and divergent and
rectangular fastenings formed at front and
rear upon opposite sides of the structure.
An eye is formed by a curved bight
adapted to enter between the guards and
engage the hook, the wire diverging from
the base of the eye to form exterior
angles, and thence converging, extending
parallel and finally turned outward to
form rectangular fastening loops.

The Link=Belt Stair Lift.
The latest contribution to elevating ma-
chinery for passengers is the Link-Belt stair
lift, the invention of the president of the
Link-Belt Engineering Co., James Mapes
Dodge of Nicetown, Philadelphia.
The stair lift, of which are here presented
several illustrations, departs radically from
other machines designed for this purpose
and possesses many unique advantages.
Its general appearance is that of the familiar
one-flight staircase. A great number of steel
links are so assembled as to make a belt flex-
ible in one direction and rigid in the other,
which is fitted at intervals with shafts carry-
ing self-oiling rollers. By means of a sta-
tionary frog, which switches the rollers al-
ternately into the upper and lower channels
of the steel sides, treads and risers are formed
at the base, presenting a smooth, flat surface
on which the passenger steps as naturally as
upon a regular step and maintains his posi-
.LWORM GEAR CONCEALED IN BALUSTRADE

tion, the steps sliding upward without jar to the floor
above, when they disappear around the sprocket
after delivering the passenger independent of any
effort of his own.
The treads and risers after passing around the
head roller again becon.e a flat belt, thus reducing
the space required for their
return and making the ver-
tical depth of the stair lift but
a trifle more than of an ordi-
nary stairway.
This construction makes a
strong and noiseless apparatus
of light weight, so that build-
ings of reasonable strength
can carry the machine with-
out the necessity of building
special foundations.
The Link-Belt stair lift oc-
cupies but little space on
either floor. Its width from
rail to rail is 3 feet. The belt
constituting the steps is 21
inches wide, experience hav-
ing shown that greater width
does not give increased actual
carrying capacity. The width
of the steps and slant of the
risers prevent overcrowding
and insure comfort to passen-
gers when every step is occu-
pied. Traveling at the rate of
90 feet a minute, with a pas-
senger on each step, 3000 per
hour can be elevated without
crowding and without the de-
lays due to waiting for an ele-
vator. This is six or seven
times the capacity of large
passenger elevators of the best
type. Under maximum load,
5 H. P. electrical current is
required to operate the ma-
chine, and as no attendant is
necessary to load or unload
passengers, its cost of opera-
tion is limited practically to the
price of the current.
The treads being level, and
the forward movement of the machine of
remarkable smoothness, no traveling hand
rail is used or required, the footing being
firm. This gives to the passenger the
free use of both hands, an advantage
greatly appreciated [where they are ac-
companied by children and carrying par-
cels. The machines can be finished to har-
monize with even the most esthetic sur-
roundings. They can be stopped or started
from either floor instantly, and in case of
panic or fire may be used as an exit. The
five figures portrayed herewith are self-
explanatory of the device described, that
will be noted with interest in connection
with its manifest need and convenience.

It has been the pleasure and the privilege of this
paper for forty years to get commendatory letters
from men whose good opinion was worth having, and
who, in renewing their subscriptions, have said kind
words regarding the value of the paper to them.
Year by year many of those who so wrote have
crossed the great divide; but yet, as the years go by,
come in increasing numbers the same kindly com-
mendations from an ever widening circle of new
readers who like the paper and say so. The paper
is cordially appreciative of such universal good-will,
and is glad to carry into the next century conscious-
ness of continued friendship and interest on the part
of so many that seems to increase in numbers and
extent as the years go by.

Probably no modern invention has been proved
capable of more extended and developed use than
the telephone. Every month evolves some new
economic phase of its applicability. The latest is
the reported project of the Northern Pacific Eailway
Company to substitute through telephone service for
its telegraph line, with intent to use the telephone
to the entire discarding of telegraph and mail serv-
ice. . The plan does not seem wholly feasible, and the
matter must be looked upon as an experiment. In
large establishments the telephone is now used as a
great saver of time, affording instant communica-
tion with different heads of departments and the
various employes. The long-distance telephone
service has seriously ^:ut the^ business of several
Eastern railroads, it being quicker, cheaper and a
saving of time for business men to talk from Chi-
cago to New York or Cincinnati to St. Louis instead
of making railway trips to and fro.
The review of West Australian mining law, the
subject of a specially written paper on page 581, is
interesting in connection with the long continued and
unsuccessful effort to secure needed changes in U. S.
mining law. The colonies do not seem to be above
profiting by experience. Since the last (or latest)
election of Stewart of Nevada to the U. S. Sen-
ate, this journal has postponed hope of manifestly
necessary changes in the Federal mining law —
changes made mandatory by conditions that do not
wait upon musty precedent or "senatorial courtesy."
The suggestion in the article in this issue regarding
the erection of public reduction plants has been a
favorite idea among some mining men for several
years, but can not meet with unqualified approval.
Anything of so paternal a tendency is not to be
strenuously advocated. Those things can best be
settled by the laws of private economic advantage,
and, while the idea may work well in Australia, it
would be a probable failure here, as the whole thing
would soon become the prey of professional politicians.
Of Public Value.
Under the auspices of the California State Mining
Bureau has been published Bulletin No. 19, the re-
sult of extensive research on the part of W. L.
Watts, E. M., concerning the oil and gas yielding
formations of California. The importance of the oil
interest and the magnitude of operations therein de-
manded such work, and the bulletin forms a com-
pendium of up-to-date scientific information on the
oil fields of California. It is of further value to any
and all anywhere interested in the geological cir-
cumstances attendant thereon, or in the economic
values of such production.
In the last four issues of this paper have appeared
copious extracts from this latest bulletin; and now
that the monograph itself has appeared, it is com-
mended to those who want complete information on
the subject of which it treats. The work has been
carefully and accurately compiled, and, like other
publications of the California Mining Bureau, will
doubtless be in universal demand.
In addition to the special articles contributed to
this paper on the subject of relative oil values, and bye-
products which have appeared during the last three
years, there is considerable matter in the latest bul-
letin that deserves notice because of the applicability
in all parts of the country of the specific information
furnished.
The bulletin shows that the ultimate analyses of
samples of oil from California and the Eastern States
compare as follows:

An examination of the. foregoing table shows that
in the California oils the content of carbon as com-
pared to that of hydrogen is greater than it is in oils
from Eastern States. Dr. Salathe says: "The re-
fining of the crude California oils is not an easy task,
and they require refining methods different from
those practiced with Eastern or Russian oils. The
complicated nature of this class of asphaltic crude
oils necessitates complete elimination of all unstable
hydrocarbons by inexpensive practical processes.
Another great difference exists between the specific
gravities of Eastern oil distillates and those of Cali-
fornia oils. Viscosity of distillate or reduced stock
being equal, the gravities are from 5° to 6° B. lower
in California oil fractions than in those of Eastern
oils. Flash and fire tests are from 10° to 30° F.
lower in California oil distillates than in Eastern dis-
tillates of the same gravity."
Following is a diagram of products available from
California crude oil by refining, showing where re-
distillation is required:

The bulletin continues: "The extraction of py-
ridine bases with dilute sulphuric acid should be done
before the redistillation of the distillates, as the
treatment of those distillates with concentrated sul-
phuric acid will otherwise form certain sulpho-
conjugated products, which, during the washing
process with water and alkali, decompose and re-
enter into solution with the refined products."
"The petroleum of the Eastern States is com-
posed principally of hydrocarbons of the paraffine
series. As previously mentioned, by far the greater
portion of the California oil is used for fuel, and that
in a crude state. It is the general opinion of those
who use oil as fuel that, weight for weight, there is
not much difference between the fuel value of oils of
different specific gravities, provided the oils are
clean, or a suitable allowance is made for water and
other foreign substances which they contain. A por-
tion of the oil is used for fluxing asphaltum and for
the manufacture of illuminating gas, and a portion is
refined. The portion refined yields crude naphtha,
illuminating oil, gas distillate, lubricating oil and as-
phaltum. The naphtha distilled from California oils
is of special value for use in gasoline engines. Those
who have made comparative tests of California and
Eastern gasoline in gasoline engines claim a su-
periority for the California product.
' ' As might be expected from the foregoing state-
ments concerning the relative composition of petro-
leum from the Eastern States and the asphaltic oil
of California, illuminating oil manufactured in this
State contains more carbon and less hydrogen than
does illuminating oil manufactured from Eastern pe-
troleums. The result is that, when burned under
similar conditions, California oil gives a more smoky
flame than does oil manufactured from Eastern pe-
troleum. This is due to the fact that it requires
more oxygen to effect the complete combustion of
carbon than it does to consume hydrogen."
" There is no doubt that, as time goes on, more use
will be made of the constituents of our asphaltic oils
in chemical manufacture."

With mining stocks "cheap" is a relative term.
There are good "cheap" stocks: cheap because the

what they do now some of those stocks will be "cheaper "
than they are now.
The Commissioner of the General Land Office states
that mining locations cannot be legally acquired within

According to figures from the San Francisco custom
house, the U. S. Government has received from Califor-
nia to June 30, 1900, from internal revenue $111,000,000,
from custom duties $264,000,000. California has yielded
a gold total of about $1,400,000,000. The Government
has spent about $13,000,000 on California— about three-
fourths of \% of what it has received.
As expected, the "Concentrate" in the issue of
Nov. 17 about longest ore shoots has elicited several
statements as to extraordinary lengths of ore shoots.
The longest heard from is that of the Smuggler-Union,
San Miguel county, Colo., which is claimed to be "over
a mile long, with one stope of 800 feet, where the ore
holds its width and grade unbroken."
To reclaim the gold from the gold-toning powder,
which contains borax and soda, dissolve the powder in

solution, wash the powder and dry it. The powder is
now to be redissolved with nitro-muriatic acid, evap-
orated and again redissolved, when chloride of gold, free
from acid, will result.
Aliens can not legally locate or hold mining claims.
An alien who has never declared his intention to become
a citizen is not a qualified locator of mining ground, and
he can not hold a mining claim, either by actual posses-
sion or by location, against one who connects himself
with the Government title by compliance with the min-
ing laws. But, upon declaring his intention to become a
citizen, an alien may have advantage of work previously
done, and of a record previously made by him in locating
a mining claim on the public mineral lands.
The tensile strength of any material is the resistance
it offers to being pulled apart. When one speaks of the
plates in a boiler having a tensile strength of 50,000
pounds por squaro inch, it is meant that if a bar of the
same metal, 1 inch squaro, is subjectod to a stress of
50,000 pounds, it will break. This is called the breaking
stress and also the ultimate tensile strength. The re-
sistance of a plate is proportional to the area of its cross-
section. When it is required to find tho breaking stress
of any piece of material, wo find tho area at the mini-
mum cross section, and multiply it by tho strength per
square inch. The tonsilo strength of wrought iron may
be taken as 50,000 pounds por squaro inch of section; that
of steel, 70,000 pounds per square inch of section. Thoso
figures may not always be found correct; an actual test
only can determine just what the tensile strength Is.
The term safe tonsilo strength refers to the load per
squaro inch that can bo borne in safety by a piece of
material. In boilers, it is usually taken at from one-sixth
to ono-fifth tho ultimate tonsilo strength of tho ma-
terial.
The Commissioner of tho General Land Office says:
"Contosts may be initiated against any entry filing or
other claim to the public lands. Thoro must be nome-
thing to protest before proceedings can be instituted.
The mere fact that land is in railroad limits does not con-
stitute a claim, because mineral lands are excepted from
the grant to the railroad. This position is illustrated by
the fact that no notice to the railroad company is re-
quired of a mineral application or entry for land which
has not been listed or selected. The fact that lands may
be selected under the Act of June 4, 1897, is no reason to
allow protest for land which at the time of filing is abso-
lutely free from any claim. The public land laws con-
template that parties possessing a claim to the public
lands will proceed to patent therefor. This is, of course,
not necessary to invest mineral claimants with a vested
right to their claims, but a mere protest is not a filing or
a claim of record; it does not segregate the land and
should not be received or noted on the records. Parties
desiring to protect their claims, without proceeding to
patent therefor, must advise themselves as to any ad-
verse claims and then proceed under the rules." These
rules were published in full in the first volume of the
issues of 1898.
The simplest method of calculating the pressure that
wrought iron and steel pipes will stand is as follows :
T X t
P = — o rcXf. Where P = safe working pressure.
T = tensile strength of plates, taking iron at 48,000 lbs.
to the square inch and steel at 75,000 lbs. t — thickness
of plates in inches or decimals of an inch. R = radius of
pipe in inches, f = proportional strength of plates, as
follows; When double-riveted = 0.7 and single-riveted
= .5. c = a coefficient or factor of safety, usually taken
at 3. p = pressure in pounds per square inch due to
head of water. Example : What is the safe working
pressure for a 36-inch pipe, double-riveted along the lon-
gitudinal seams, and made from wrought iron plates,
rolled across the grain, and J of an inch thick ? Answer :
T t
48000 X -125 c f
P = jg ■- 3 X 0.7 = 77.7 pounds to the square
inch, or 179 feet pressure head. By means of tho same
formula the thickness of plate is easily found that
will safely stand any given pressure. For instance :

In recovery of the silver in the U. S. Mint, the silver
solutions, together with the wash waters from the gold
treatment, are transferred to a precipitation tank —
capacity 2000 gallons, never filled to its full capacity,
since abundant room must be left for stirring and rous-
ing the contents. Salt water is run into the silver solu-
tion until a test shows that enough has been added to
convert all silver present into chloride. An excess is
avoided, since silver chloride is slightly soluble in salt
water. The contents of the tub are drawn off through a
filter, a wooden tank 6.] feet long, 3 wide and 1J in depth,
lead lined and provided with a perforated false bottom,
the bottom and sides carefully covered with cotton
cloths as a filtering medium. The curd-like silver chlo-
ride is run into this filter through a large wooden stop-
cock. The liquid which drains off is returned to the
filter until it runs clear, after which it is passed through
several traps to the sewer. Fresh water is passed
through the chloride until all soluble matters are re-
moved, when it is allowed to drain. The filter tank is
mounted on low wheels for convenience of removing
the chloride to the reducing vat. This is again a lead-
lined rectangular tank. The silver chloride is trans-
ferred to this tank by a copper scoop shovel. Hot water
is run on, and granulated zinc added in sufficient quan-
tity to reduce the chloride to metallic silver. The addi-
tion of sulphuric acid hastens the action and serves to
dissolve the slight surplus of zinc which it is necessary to
use to insure complete conversion into metallic silver.
The reduced silver is now taken out with a copper scoop
having a shovel handle and put into a filter colander, in
which the silver is washed with hot water until entirely
sweet. It is now ready for compression into solid cakes by
hydraulic pressure. These cakes are dried in a current
of hot air, when they are ready for melting. This is
usually done without fluxes, and the resulting bars have
a fineness of 0.998 to 0.999.

Review of West Australian Mining
Laws: A Comparison.
Written for the Mining and Scientific Press by George Hope.
The American mining laws, created over a quarter
of a century ago by legislators not practically ac-
quainted with the subject on which they framed their
enactments, have worked out constantly in practice,
not so much to the benefit of the industry they were
intended to serve, as to the individual profit of those
interested in stirring up litigation on all possible
points. There is scarcely a clause on the statute
book through which a coach and four can not be
driveu by the skilled legal practitioner, and while the
mining industry, of all others, has been a record of
constant progression, the laws that govern it have
virtually stood still, till a demand, universal and im-
perative, has arisen for amelioration and revision.
That a radical change need not be necessarily hostile
to vested interests has been proved in the successful
efforts to bring the laws and regulations up in line
with the requirements of the industry that have en-
gaged the attention of the Australasian parliaments
almost every session of late years.
In the case of West Australia, in what was practi-
cally a sterile desert a decade ago. one-third the size
of the United Slates, a gold-mining population is now
peaceably working under laws that embrace every
phase of widely differing interests with a maximum
of security and a minimum of litigation. True, in the
case of a new country, the lessons learned the world
over in practice could be and were applied without
friction, and many valuable suggestions may be gained
from a brief review of the salient features which have
tended towards a successful control of the industry
there and may serve to guide judgment in the revis-
ion of the law so urgently needed at home.
The fundamental principles of the Australian stat-
utes as applied to mining differ essentially from those
of the United States. Where lands were alienated
from the Crown in times past, no reservation of min-
erals was made, and a special Act dealing with
''mining on private property" was passed. The
provisions of this Act are in no wise so liberal as our
own laws in similar case. Most of the metalliferous
country, however, lies in the barren interior, and the
fee simple to this remains vested in the Crown, areas
being leased in tracts not exceeding twenty-four
acres for a term up to twenty-one years at an annual
rental of $5 per acre, and the fulfillment of certain
labor conditions defined by law are a part of the
rental due and payable. Xo patents are ever issued.
Another essential point of difference lies in the fact
that there are no extralateral rights to cause con-
flict, a lessee being only entitled to the minerals
within his corner pegs. Thus, if a ledge dips at a
shallow angle out of a leased area, it belongs to the
holder of the adjoining ground on the underlay side
so soon as it passes beyond the limit of the side line of
the original claim. A lease may not exceed in length
along the line of the ledge more than twice its
breadth, but there is nothing to prevent a person
taking up two, or even three, leases, side by side.
covering the underlay of a ledge to an indefinite depth.
The object of the limitation of the lease area is two-
fold. It prevents the locking up of large tracts of
valuable ground without adequate development, and
it conserves the rights of labor in a democratic com-
munity equally with those of capital, for the employ-
ment of one man to every six acres is compulsory on
each and every lease. Easements and exemptions
are allowed, if applied for in open court, when ob-
jections from any interested party may be lodged,
for certain specified reasons, such as inflow of water,
collapse of workings or shaft, absence of machinery,
or other cause, deemed sufficient by the Warden of
the Goldfield. In the case of two or more parallel
ledges, the underlay claim is often more valuable than
the original location, though there is no reason why
the first locator should not have secured them both.
Thus:
Should any leaseholder suspect that any neighbor ■
has worked out the ledge on his lease and is trespass- '
ing into his own ground, he applies to the Warden for
permission of entry of a surveyor. This is readily
granted and the division lines of the two claims un-
derground are correctly ascertained. Cases have
occurred where a ledge, after going down a hundred
i" so. has turned and eomeup to the surface
again on an adjoining holding. Here, this might
cause endless trouble : in Australia it creates none.
The same is true of a Y-shaped vein with two out-
crops. It is immaterial which is the prior location
or which the mother vein and which the feeder.
The same argument holds with ledges that cross
each other or lie partly in one claim, partly in
another.
Two main divisions are recognized in the Austra-
lian laws, one portion being devoted to alluvial, or
placer, mining, the other to reef, or ledge, mining.
In West Australia water is absent : the country is
flat and the gold lies close to the ledge from which it
was derived. Dry washing, or, as it is called there.
'• dry blowing." is the means of recovery availed of.
An alluvial may work ground up to within 50 feet of
the ledge or leased ground. He may enter upon any
"ease and call up the owner or manager to define the
strike of his ledge, and may work up to 50 feet of
such line on either side. In Queensland no leasing is
permitted until two years after discovery of
auriferous ground, so that the alluvial may first ex-
haust the surface deposits. In West Australia
ground known to contain alluvial gold can not be
leaspd until abandoned by the alluvial diggers. The
surface deposits being shallow and the process of allu-
vial recovery rapid, no great injury is worked to the
deep mining industry as a whole.
For quartz mining the process is as follows :
Armed with his miners right, the prospector maps
the outcrops till sufficient color warrants a location.
He then has the right to mark out a prospecting
area 160 yards square to hold the ground while he
investigates its merits. This " pegging out" will
hold the ground for thirty days, at the end of which
time he must register his claim (cost $2.50) at the
nearest registrar's office. This affords a clean title
till payable gold is struck, when notice must be given
to the Warden and a lease applied for. A lease, of
course, may be applied for on any ground without
first holding it as a prospecting area, which is de-
signed for the poor man only. When a lease is desired,
the area wanted is defined by corner pegs, trenches
and cleared lines as nearly correct as possible : no-
tices of intention are posted and application made for
the lease within ten days of marking. The fees must
be paid on application. $5 per acre per year rental
being deposited for the first year in advance, to-
gether with the fee for survey, from $20 to £50. At
the end of thirty days the application is heard in
open court, when all objections are considered. If no
valid objections are sustained, the lease is recom-
mended by the Warden and issued later by the Min-
ister of Mines. Immediately upon its recommenda-
tion the labor conditions come into force. For the
first six months one man for every twelve acres: after
that, one man for every six acres, must be con-
stantly employed for eight hours five days in the
week, four hours on Saturday. A lapse of three days
in the labor conditions renders a lease liable to for-
feiture on the application of any person applying for
the same and proving the default. The case is tried
by the Warden in open court and his decision is
handed to the Minister for decision. The fulfillment
of the labor conditions is part of the consideration
paid to the Government for the lease.
When several leases are held by one ownership the
Warden may. on application, allow the due comple-
ment of labor for the total lease to be concentrated
on one particular lease. The object in all cases is to
have the ground developed and prevent its being
locked up in large areas by speculators. Under I
laws scores of propositions were floated on the Lon-
don market during the late mining boom at Cool- i
gardie and Kalgoorlie. To the bona fide company no
hardship was worked. Working capital was sub-
scribed and active mining prosecuted. To the wild-
cat concern it proved a wholesome deterrent. After
excuses :'or icllezess were exhausted ir. the Warder. $
court on pleas for exemption, the properties were
mostly abandoned, if worthless, or leased on tribute.
The writer recalls a dozen properties held by London
companies that, through bad management or other
cause, were abandoned or shut down, and which are
now producing ore running from $15 to $40 per ton
in the hands of practical men or working tribu-
tors. Xbn-payment of rent will forfeit a lease, also,
and the conditions appear stringent at first sigh: . it
is under these conditions that Kalgoorlie. with its
gigantic plants and invested capital, is working its
mines to-day. The principle, though novel and social- ,
is::.' is sound in practice and has tended to purify
gold mining, as an industry, of some of its worst and
most unwholesome abuses.
For purposes of efficient jurisdiction, the auriferous :
country in Australia is divided into separate gold
fields, each under the charge of a Warden and a
Registrar. A Warden's court is established, in
which mining disputes are tried, pleas for exemption
from labor conditions heard and the like business
transacted. Xo one has a locus standi in this court
without a miner's right, which every miner is required
to secure and renew annually at a charge of $2.50 —
formerly $5. Anybody can appear to conduct a . a s e
not necessarily a qualified legal practitioner. The
Warden is endowed with the power of a Supreme
Court judge in many cases : but, being chosen for bis
tact, judgment and experience, he is enabled to check
litigation and obviate expensive appeals. Had justice
suffered under this "mild Casarian despotism."
an outcrv for a change, would have undoubtedly i
arisen. The contrary has been the case : rich and
poor, capital and labor, being satisfied with the ma-
chinery provided for maintaining their rights.
Throughout Australia the fostering care of the
central Government is everywhere apparent. Thev
build the roads, provide water supply, overcome the
prohibitive veto of costly transportation for fuel,
timber and supplies generally by building railways to
promising centers — and this, not with a view to profit
earning, but solely as an encouragement to the min-
ing industry, carrying low-grade ore for 1 cent per
ton per mile in some cases, recognizing always the
economic truth that when $10 rock, scattered over a
large area and hitherto irreducible at a profit, can
be successfully treated for $S. then capital is forth-
coming, population attracted and the latent element
of a national wealth availed of to the utmost.
This policy of encouragement has been lately ex-
tended in a new direction with the happiest results,
affording an object lesson in State socialism we may
well afford to study here in the development of the
-New West. Two years ago the West Australian
Government voted a quarter of a million dollars to be
expended in the erection of public reduction plants in
districts where indications showed capacity to sup-
port a population of diggers and small claim holders.
Locations in plenty were held by individual miners
who could neither sell nor raise funds to hold on and
develop. In such centers mills were erected after
careful inspection of auriferous possibilities by ex-
perts, the charges for treatment being fixed to cover
cost of handling, of management and of providing for
interest and sinking fund on the money borrowed by
the Government under the grant. Last year nine
batteries were successfully operating at an average
charge of $2.75 per ton to the miner in a country
where water and fuel are costly luxuries. They paid
all the costs enumerated above and indirectly added
thousands to the national treasury. The effect, in spite
of many adverse predictions, was magical. Town-
ships sprung up around the batteries and hundreds
of useful citizens found profitable employment in op-
erating ledges hitherto valueless. Another vote in
expansion of the policy was granted by Parliament
quite recently.
An example of the beneficial effects accruing from
the erection of public reduction works may be seen
in Shasta county. CaL. where the smelter of the
Mountain Copper Co.. Ltd.. at Keswick, absorbs
large quantities of low-grade quartz mined by small
claim holders in the vicinity, who would otherwise be
looking for work — supporting, in fact, a very consid-
erable population of independent miners, and. by the
exigencies of its own requirements for flux, doing it
at a very cheap rate to its customers. There is room
in the low-grade ore belts of California for half a
dozen smelters erected in suitable localities.
not for profit, but on the co-operative plan, with
money advanced by the Government and operated on
a scale of charges that will repay the loan in. say.
thirty years, principal, interest and all intermediate
expenses. It has not been found in Australia that
the Government ownership of "public batteries
(custom mills) interferes in any way with capital seek-
ing legitimate avenues of investment.
The foregoing is merely a sketeti — a brief outline —
of the general principles governing the industry in
West Australia. The regulations which follow and
form part of the mining Act in force cover every de-
tail and are readily comprehensible to the digger of
ordinary intelligence, so that he is enabled to fill out
his own forms and transact his business without the
aid of a lawyer or middleman. Active development
is aimed at. so that the auriferous resources of the
country may become national assets of practical,
revenue-producing utility to all concerned.
To Users of Auger Bits.
To the Epitob: — It frequently occurs that the
operator bores a hole xs or i too small for the bolt,
or other purposes intended, and. naturally, the next
move is to secure a bit the proper size and to rebore
or ream out the hole: but nine times out of ten the bit-
will work its way through like a screw and not ac-
complish the desired effect. If the operator will re-
verse his stroke. L e.. turn backward instead of
forward from the start, the same bit, if of the Russell
Jennings pattern, will cut a clean, smooth hole.
Redding. Gal Wm. Stephens.
Regarding the governing of turbines in a gener-
ating station at Davos, in Switzerland, there are four
200 H. P. turbines worked under a fall of 330 feet : if
automatic governors were slipped under such a high
fall, a sudden change of load would cause the gate of
the turbine to shut very rapidly, and the sudden
change of velocity of the water in the pipes would
produce a shock, or excess of pressure, which is all
the more dangerous the longer the pipes. In this
.use :he pipes are 7200 feet long. To prevent the
water hammer, there is a large air vessel about 4
feet in diameter and 40 feet high, connected with the
main pipes, and also a special contrivance connected
with the automatic governor, to open automatically
the waste water valve and furnish an exit for the
water as soon as the governor acted on the gates of
the turbines. If the load is taken off suddenly, the
normal speed of the dynamo does not change more
than 4.V which appears satisfactory.

A California Gold Dredger.
Written for tbo Minino and SciENTiric Pkkhh by
R. H. POHTI.KTIIWAITK.
As dredging for (fold is now coming into such prom-
inence in this oountry, a brief desorlptlon of the lat-
est dredger on the l-'i-a t lii-t- river, designed by the
writer and built by the Kisdon Iron Works for the
Marigold Dredging Co., maybe of interest.
This dredger- Is of the standard Kisdon type of gold
dredger, similar in principle to those already built,
and described in the Minimi AND SOUNTTMC P
but embodying many improvements and additions
which have proved fully adapted to their various
uses. The dredger will dig from a depth of 30 feet
below the surface of the water and elevate the tail-
ings to 30 feet above the water level, which will en-
able it to handle a bank at least IB feet above water
level.
The ladder consists of a heavy lattice girder with
J-ineh side plates, 3 feet deep in the center and taper-

ing off to 2j feet at each end. The lower end carries
a pentagonal cast steel tumbler and has a unique
feature (protection for which is applied for) consist-
ing of a strong stop or fender made of heavy plate
and angle iron. The purpose of this is to get rid of
the accident common to all continuous bucket ma-
chines, of the bucket belt occasionally leading off the
lower tumbler, which, besides wasting time, is liable
The Marigold Dredger, Oroville, Cal,
to cause serious damage. With this new stop, the
bucket belt, when first starting to climb the flange,
strikes the stop which is sufficiently strong to release
the friction clutch. When this occurs all that is
necessary to run the belt on again is to reverse the
j motor a few turns, which can be done in less than
three minutes.
The ladder is provided with steel chafing rollers
running against steel I beams built into the hull,
which gives a smoother motion than the old style
chafing beams, and reduces the wear and tear to a
minimum. The belt travels upon cast steel rollers
running in enclosed grease cup bearings, which sys-
tem of lubrication is used for all parts subject to wa-
ter and grit, and has proved very successful.
The bucket belt consists of thirty-two heavy, sub-
stantial buckets, each of a full 5 cubic feet capacity.
These buckets have cast steel links bushed with man-
ganese steel, and are heavily reinforced from the link
! some inches up the side. The lips, which are easily
I renewable, are made of a special grade of nickel steel
which has undergone a special treatment to make it
withstand the heavy blows, at the same time being
hard so as to stand abrasion. The lips are 7 inches
wide and 1 inch thick. The buckets are connected
together with cast steel links and forged manganese
pins. Tin- top i bier over which the bell travels is
square, with renewable east steel wearing strips, the
design being very heavy and solid.
The main gantry, wiiieh carries the tumbler and
countershafts, is of steel throughout and has pi
absolutely rigid, This is o f tl I Improve
ments on the dredger, and the extra first cost will be
far more than counterbalanced by its InCI

the excessive heal and dryness causes the joints to
shrink, which necessitates constant tightening up of
bolts, and even then hearings are apt to gel, mi of
line and oaut e I rouble,
The main bucket belt is driven through a train of
gears and one belt by induction motor of 50 II. P.,
taking a three-phase current at 1000 volts. The
average borse power consumed, however, does not,
exceed 25 II. I'., dumping twelve and one-half buck-
els per minute, which gives a capacity of approxi-
mately l">0 cubic yards per hour. The material
dumps into a steel delivery plate which conveys it
into the revolving screen. Under the delivery plate
are placed three sets of bar grizzlies which catch any
drip there may be from the buckets.
The revolving screen is I' feet in
diameter by 25 Feet long, perforated
with i-incfa diameter holes. The
screen carries on its lower end a
heavy cast steel ring; under this
ring is a cast iron self-contained
bedplate carrying friction rollers
driven by steel bevel wheels, all
bearings being brass bushed and
having the end thrust taken up by
fiber washers. The brasses are
made interchangeable and rever-
sible, to allow of the utmost amount
of wear being taken out of them.
The screen delivers the coarse
material directly onto the stacker
buckets, which are of the Kisdon
standard typo, carried by steel I
beams of sufficient length to elevate
the material 30 feet above water
level; both top and bottom tumblers
are cast steel and five-sided. This
elevator belt, instead of being
driven from the top end by moans
of a rope transmission from the main shaft, is driven
from the lower end by the same induction motor which
drives the screen. Motion is conveyed from this motor
to both the screen and elevator by means of a chain of
gears carried by shafts running in babbitted bear-
ings fitted onto a self-contained cast iron bedplate,
which also carries the motor, thus insuring true
alignment and pitch distance, which cannot be per-
manently secured where the sev-
eral bearings are bolted onto tim-
ber.
The water supply is furnished by
two centrifugal pumps, direct
coupled, one on each side of an in-
duction motor, one pump delivering
2000 gallons per minute into the
screen through a perforated pipe,
and the other supplying water into
the distributing box and various
save-all grizzlies. The pump takes
about 30 H. P. to drive it, and
owing to its construction does away
with all troubles from belts. The
gold and fine material passes
through the perforations of the
screen into the distributing box and
over 300 square feet of standard
Risdon tables which practically
save all the gold. The sand and
small gravel is then delivered be-
hind the dredger by a sluiceway
fitted with riffles. Under one sluice
a sump is arranged from which a
direct connected centrifugal sand
pump takes the sand and some of the water and
deposits it over the top of the tailings. This pump is
lined with renewable liners and takes about 10 H. P.
to drive it, and is only used very occasionally if a
sand fill requires to be cut through.
The winches on this dredger show great advantages
over those formerly used and are entirely new in de-
sign. The main winch is directly geared with steel
gears to a 10 H. P. induction motor. The operating
handles work in quadrants of locomotive type and are
all brought to one platform, one handle for each of
the four side-line drums. The design is such that the
movement of one handle enables a drum to be in-
stantly set in motion, allowed to run loose, or held by
the brake ; each drum is entirely independent and can
be operated in any way regardless of the condition
of the others, whether driven, loose or held. This
prevents any delay in changing the position of the
dredger, and, together with the independent ladder
winch, will increase the actual capacity of the dredge
probably 30% over the old style. The head line is
operated by a slow-running drum, giving a steady
but very powerful advance to the dredge. The lad-
der winch is entirely independent and consists of a
15 H. P. induction crane mofor, fitted with brake
and controller by which the ladder can be rapidly
owered, the rope speed being 100 feet per

ment. The crew r sisls of two men per shift and

$50,000 in complete running order-.
Platinum.
Tho platinum of commerce has been obtained en-
tirely from alluvial deposits, although it has been
reported in limited quantifies in situ, About 80% of
the present supply is derived from the alluvial depos-
its of the Ural mountains, but there are few, if any,
of the gold-bearing gravel beds of the world that
have failed to yield platinum, and it is more than
likely that large quantities of platinum ore have been
thrown away with flic black sand washings from gold
placer deposits. The distribution of platinum may be
regarded as coexistent with gold placer deposits, as
is evidenced by the list of localities, excepting Rus-
sia, that have yielded it in varying quantities. In.
California in nearly if not all of the gold-bearing
gravel and sands ; in Oregon, Georgia, Alaskaon the
Yukon river, Canada, British Columbia, Mexico,
Colombia and Brazil, South America and Australia.
The genesis of the native platinum is not well under-
stood. In two cases the metal has been reported as
found in quartz veins, but these reports havo never
been verified and are open to grave doubt. The un-
doubted occurrences of platinum in situ are in Rus-
sia, Brazil, New South Wales, Canada and Colombia.
Platinum is usually found in the form of rounded or
flattened grains of " sand," occasionally in irregular
lumps of the size of peas; large nuggets are very
rare — the largest as yet found weighing twenty-one
pounds. The ore has a metallic luster and is dis-
tinguished by its steel-gray color, shining light gray
streak when rubbed on a hard white surface, high
specific gravity (IK to 19), malleability, infusibility in
the hottest blast furnaces and not affected by borax
or salt of phosphorus before the blowpipe, except in
the finely divided state, when reaction for iron and
copper may be obtained. It is soluble only in hot
nitro-hydrochloric acid. The method generally
adopted for extracting the ore is to pass the sand
and water with gravel through puddling machines
or revolving conical screens; the platinum and fine
sand pass through into sluiceboxes beneath, while
coarser materials are discharged at one side. The
contents of the sluiceboxes are washed in the usual
manner, and when gold is present in paying quanti-
ties it is removed by amalgamation with mercury,
the platinum remaining behind. Experience shows
that it is seldom profitable to work mines yielding
less than three grams of platinum ore to the ton of
gravel. The average yield of the richest Russian
mines is about six grams per ton. Platinum has an
affinity for iron, and is never without it. It alloys
with copper, but is never found with it.
Large Storage Battery.
The Baltimore & Ohio Railroad has contracted for
a huge storage battery to be used in hauling its
trains through the Baltimore belt tunnel by electric-
ity. This battery will consist of 320 tanks made of
hard wood, lined with lead, each holding thirty-nine
plates, nineteen negative and positive. Each tank
will weigh, with plates and electrolyte, about 1800
pounds, and the complete battery will have a capac-
ity of 1200 H. P. for a short period of time. The
horse power of the electric locomotive ranges from
1000 to 1500, and this entire load has to be supplied
by the power house at present. As the load is only
required when the locomotive is in action, it is a spas-
modic demand, the average use throughout the day
being less than 500 H. P. When the battery is put
into service, it will act as a reservoir of power, ac-
cumulating electricity while the locomotive is not in
use, and relieving the power station of the load above
the average by discharging into the line this accu-
mulated current.

Jobbers and flanufacturers.
Eastern exchanges give considerable attention to
a peculiar controversy between some San Francisco
jobbing houses and the Selby Smelting & Lead Com-
pany as regards the handling of loaded shells, shot,
lead pipe, sheet lead and other goods manufactured
by the Selby Smelting & Lead Company at their
cartridge factory and shot tower, which is one of the
oldest institutions in California, and, because of its
position as smelters and refiners of precious metals
and low-grade ores, has a national reputation. In
addition to smelting and refining the various ores and
bullion, they are large dealers in tin, copper, zinc,
antimony, etc. It has always been assumed that the
Selby Smelting & Lead Company not only has the
ability, but also the disposition, to be liberal ; that
they were specially anxious to protect all dealers
against encroachments, thus endeavoring not only to
promote local enterprises, but to make it to the in-
terest of dealers to get their supplies in San Fran-
cisco.
The chief cause of the trouble appears to be that
the jobbers complain that the Selby Smelting & Lead
Company insists upon selling to certain San Fran-
cisco retailers and plumbers. The jobbers claim
that, as manufacturers, the Selby Company should
distribute their goods only through the jobbers. The
latter have a combination — the Pacific Coast Hard-
ware & Metal Association — whose first object is to
promote good feeling and cordial relations among the
different jobbing houses on "the Pacific coast, and
having in view definitely co-operation in endeavoring
to secure better freight rates, and exercising such
influence with the railroad and transportation com-
panies as to protect them against the jobbing houses
of the East. The association is now contesting with
St. Louis and other jobbers before the Interstate
Commerce Commission for better freight rates on
less than carload lots from the East to the Pacific
coast. Locally, however, some members of the As-
sociation have endeavored to exercise control over
manufacturers declining to buy goods from any
manufacturer who sells to retailers.
One of the difficulties is to know where to draw
the line between jobbers and retailers. The general
definition of what constitutes a jobber or wholesaler
is a concern which sells more goods at wholesale than
it does at retail. Some, in endeavoring to define the
position more exactly, state that only a concern
which sells at least 75% of its goods in whole pack-
ages should be considered a jobber. Many retail
establishments do a large business, and will sell in
any quantities they find best. Some of these houses
have such great ability that they can handle
goods to great advantage, and thus it seems in-
consistent for certain jobbing houses to discriminate
against such retailers. Reference to the customs in
vogue among Eastern firms shows that they have
had there the same difficulties to contend with, and
that it is a positive rule with many manufacturers to
establish schedules of prices on quantities, always
favoring the larger dealer with a better percentage
than the smaller dealer — schedules of prices being so
arranged that the jobber, when buying in quantities,
has such margin reserved to him by the manufac-
turer that he can sell the retailer at a reasonable
profit. Where the business is managed with proper
consideration for all interests, the jobbing houses are
able to control the larger portion of the business ;
but there are some retailers who, having ability, are
able to buy in quantities which seem to entitle them
to more favorable terms than the ordinary retail
concern, these houses having large capital deeming
themselves entitled to consideration. The relations
between the manufacturer and the dealer should
always be amicable, co-operating on a basis whereby
all the various interests may be harmonized, and in
special localities work together in protecting their
own industries.
Viewed from an impartial standpoint, it does not
seem just that the jobber should claim to himself the
right to dictate to the manufacturers how they should
dispose of their products. On this line it has been
the practice of some of the jobbers to base their mar-
gin of sales on the average yearly cost of doing busi-
ness, and in some instances they have insisted upon
charging the small retailer a price which would yield
them from 17% to 25%, because they say it costs them
from 15% to 171% to do business. The large Eastern
jobbers figure differently, and seem disposed to sell
on a very close margin of from 2J% to 5%, calculating
to turn over their money not less than six times
every year; and at the rate of 11% it is manifest
that they have at the end of the year their 15%.
These parties are jobbers ; they aim to do business
on a large scale, and to make their profit from the
volume of business and frequent transactions, assert-
ing that this is the better way. It is not wise to try to
make the full measure of profit from each individual
transaction.
The position of San Francisco, and the coast cities,
is different now from what it was before the comple-
tion of the many railroads; the extremes of the
country are coming closer together. Merchants and
dealers on this coast should be satisfied with less
margins on individual transactions, but aim to in-
crease their profits by frequent transactions and
larger volume of business. This can be done by
adopting more liberal policy all round, and not
attempting to oppress small dealers, or to incon-
venience manufacturers. It seems to be the policy
of the Selby Smelting & Lead Co. to adopt the same
general plans as prevail in the East, by establishing
such schedules as will protect the large dealer in a
margin of profit, and also the small dealer against
ruinous competition. It is not good business policy
to ignore certain interests which it should be mutual
pleasure, as it certainly would be ultimate profit, to
conciliate.
The Selby Smelting & Lead Company use their
shot tower as one of the channels for disposing of the
lead produced at their refinery; they have also other
channels open, and supply demand for their pig lead
and manufactured materials from places tributary to
San Francisco. They are able to compete with the
East on this coast because the cost of lead in their
ores and base bullion is purchased at prices cor-
responding with the Eastern cities; they have the
advantage of freight from the East, and are enabled
to distribute from this point in competition with
Eastern manufacturers. They do not belong to the
Trust. They have not sought to invade Eastern
territory, and have reciprocal understandings with
the various manufacturers in the East of their
products, so that as a rule the Selby Company has
not attempted to interfere with the trade of the
Eastern manufacturers, and although at times they
have a surplus of pig lead which could be manufac-
tured and distributed to advantage, they have in
good faith preferred to ship the pig lead to New
York, and sold there rather than cause any dis-
turbance.
It were better for mutual good that the contend-
ing parties get together and harmonize disputes to
the end that all local interests be protected.
Shipping Molten Iron.
The construction of a new bridge across the Monon-
gahela, Pa., directs attention to a striking feature
of modern metallurgy. The usual way to make steel
is to melt cold pig iron, to which other materials are
added, and then purify the mixture by burning out
certain undesirable elements. Pig iron, however, is
itself the product of a previous heating process, in
which the ore is melted up with carbonate of lime to
remove the oxygen. It occurred to some ingenious
metallurgist that if the product of the blast furnace
could be converted into steel before it had cooled
sensibly a great economy in fuel could be secured.
The bridge mentioned has been built for the Car-
negie Co./. and will be used to convey molten iron
from the Carrie furnaces to the Homestead Steel
Works, a mile away. At the present time Home-
stead obtains molten metal from Duquesne, 4* miles
away. The new route has been laid out so as to save
time, distance and heat. There has been for some
time one hot metal bridge across the Monongahela,
controlled by the Carnegie Co., and, besides the new
one about to be opened, a third is in process of erec-
tion for the Jones & McLaughlin interest.
One gets a vivid idea of this remarkable procedure
when he reads about the precautions taken in the con-
struction of the new bridge to prevent harm in case
any melted metal leaks or slops over while in transit
from the iron furnace to the steel works. The spaces
between the ties are to be filled with sand, so that
no iron may fall to the decks of passing steamers.
The ties will be of wood, but are to be protected by a
covering of sand. On either side of the track there
will be raised a screen of heavy metal plates, faced
with firebrick and reaching to the height of 4 feet.
An extension of thinner plates will bring the screen
up 6 feet farther. The cars are ladle-shaped and the
molten metal runs directly into them when the fur-
naces are tapped. A locomotive then draws the
train to the steel works at a moderate pace.
Broken Hill Sulphides.
A circular from Wm. Lidderdale, chairman of the
Broken Hill Smelting Corporation, Australia, says :
" The directors have much pleasure in reporting to
the shareholders that their process for treating
mixed sulphide ores of lead, ziuc, silver, etc., is now
in complete operation at the Stanlow Works, Elles-
mere Port. The process makes a full and satisfac-
tory separation of the zinc from the lead, silver, gold,
etc., and the recovery of metals, especially in silver
and lead, promises to exceed the original estimates.
On the ore already smelted the recovery of lead and
silver is higher than was realized at the works at
Llansamlet. The recover}' of zinc has already reached
upwards of 60%, and is improving. The directors
have every reason to believe that the 70% originally
promised will shortly be attained. In starting new
works of every description some initial mechanical
difficulties are invariably experienced before all the
various parts of the plant work satisfactorily. This
has been the case at Ellesmere Port, but the difficul-
ties have been purely mechanical and not such as to
affect the soundness of the process. Owing to this,
and the very great rise in the value of coal and all
other smelting materials, the working costs have
hitherto been in excess of the estimate made at the
beginning of 1898, but »s important savings are being
effected in sundry directions, your directors believe
that eventually the working costs will exceed but lit-
tle, if at all, the original estimates. The directors
have no hesitation in assuring the shareholders that
the important and difficult problem of treating mixed
sulphide ores, which has created so much interest in
metallurgical circles for years past, has been com-
pletely and satisfactorily solved by the process which
is owned by the Smelting Corporation. During the
last few weeks an inquiry has been received from a
well-known and experienced smelter in the United
States as to the directors' willingness to sell or lease
the patent for that country, where large deposits of
rich sulphide ores have been long awaiting a satis-
factory process for their successful treatment."
New Metallurgical Process.
m
In the issue of Aug. 11, 1900, appeared an ex-
tended account of a new metallurgical process that
attracted universal attention. In answer to numer-
ous inquiries, it may be stated that the experiments
there spoken of as carried out by Dr. Goldschmidt
with aluminum as a reducing agent are now con-
sidered to have passed from the experimental stage.
According to a paper read by Mr. Lange at the Paris
meeting of the Iron & Steel Institute, the success of
Dr. Goldschmidt's method is due to the fact that he
found that the reducing mixture need not be heated
from the outside; it is only necessary that the re-
action be started, and this is done with the aid of a
mixture of powdered aluminum and some peroxide,
barium peroxide by preference. This mixture is now
prepared by the Societe d'Electro Chimie, Paris,
under the name of "alumino-thermie." For en-
gineers there has been prepared a substance called
"thermit," a preparation of iron oxide, Fe2, O., and
aluminum, its chief use being for repairs of large
pieces which can not be heated in the ordinary way —
such, for instance, as welding the ends of rails to-
gether, or replacing a tooth on a broken wheel. As- j
suming that a new tooth is the object sought, it is
moulded in situ in fireclay, clay and coke, with or
without the addition of sand. Then the required
amount of " thermit " is melted in a special crucible,
supplied by the company, one pound of the mixture
giving one-half pound of iron. * * * *
To start the operation, a pound or two of " ther-
mit " is placed in the crucible and some of the primer
(aluminum and peroxide), about 1% of the mass, is
strewn on this. Ignition is set up by throwing a
lighted match on top of the primer or by dipping a red-
hot iron wire into the mixture. The reaction starts
suddenly. More " thermit " is strewn — not thrown —
into the white-hot mass, until the desired weight has
become molten. The temperature is estimated at
3000° C. The liquid corundum is poured off, and then
the iron is poured into the mould. The piece is
slowly cooled and the tooth hammered and filed down
to the required dimensions. It would seem, however,
that the process has achieved the greatest success
in welding proper, for some test bars welded with
thermit and shown at the meeting gave a strength
of 36.8 kilogrammes, against 35.8 kilogrammes per
square millimeter before treatment, and an elonga-
tion of 11.5% as against 15%. The tensile strength
was thus impaired, but the fracture occurred some
distance from the weld. To the boilermaker it will,
however, perhaps be most interesting to note that
tubes which have been welded endways with this
process have withstood a pressure of 400 atmos-
pheres, finally splitting lengthways when hammered
or bent, but not breaking at the joints. Flanged
tubes of this type would not have stood more than
half the pressure, and the achievement is all the more
noteworthy when it is considered that only the edges
of the tubes are in contact.
Success Dependent Upon Success.
There is no other profession in the world so de-
pendent for success on the smiles of Dame Fortune
as that of mining. A lawyer counts but on himself
to achieve position ; a doctor earns honor by his own
ability ; but with the mine manager, fortune must be
with him in his mine, and, even when so, success is
only assured when followed by his own exertions,
splendid organization, mining knowledge and man-
agement. No profession calls for men of hardier
constitutions, pluckier hearts or of more intelligence,
and to be successful in its ranks is to reach a goal
which may well be envied by the rest of our fellow
men. The life of a mine manager is a continual gam-
ble. He is often expected to achieve results where
there is no mine, and pay dividends where the most
expert management can only meet expenses. The
profession might well be called a lottery, which has,
however, a big drag in favor of the bank, and, even
when a prize is drawn in the shape of a good mine, it
is only won after the years of study have been turned
to such account as to make it a success, and that
bigger than anticipated. No profession numbers in
its ranks such a quantity of good fellows ; the fortu-
nate of one day are the unfortunate of the next ; this
tends to make men like each other for their qualities
alone, and leaves a silken thread of good fellowship
running through them which is the envy of all other
professions and the pride of their own. The help-
ing hand should be extended by the fortunate one of
to-day to those of yesterday, or, let us hope, of to-
morrow.— Machinery Register.

Oil and Gas Yielding Formations of California.
NUMBER IV.— CONCLUDED.
During the early development of the Oil City field,
much inconvenience was experienced through lack of
water. In 1899, J. A. McClurg sunk two 275-foot
wells in the valley land about 6 miles southwest of Oil
City. The formation is : Drift to 200 feet, water-
gravel to 212 feet, tough clay to 275 feet. The water
rose about 5 feet in the casing. These wells yield an
immense supply. Two 4-inch steam pumps are being
used to pump the water into the receiving tank. A
duplex Dow pump, having a capacity of more than
15,000 gallons in twelve hours, forces the water
through 6 miles of 3-inch pipe to an elevation of 275
feet above the top of the wells. The oil field con-
sumes about 15,000 barrels of water every twenty-
four hours. This is potable water and rather hard.
The output of water from the Oil City field during
1899 was 439,372 barrels. The oil is conveyed by pipe
line from Oil City to Ora station on the S. P. R. E. ,
a distance of Si miles.
The Alcalde field is about 3 miles southwest of
Coalinga and extends from the old coal mines, which
are about 4 miles a little west of north from Coalinga,
to Alcalde creek. The petroleum claims on .which
prospect wells have been drilled are situated in the
first two tiers of foothills which run in a southeasterly
direction from the old coal mines. These foothills are
for the most part formed of sandstone containing fos-
sils of the Middle Neocene age. It is conceded that
these Neocene rocks lie non-conformably on the
Eocene, although the dip of the two formations is
about the same. No white shale is seen between the
Eocene and Middle Neocene formations in this local-
ity except a slight outcrop near the San Joaquin
coal mine. In 1893 the writer obtained a small
collection of fossils from the San Joaquin and Cali-
fornia coal mines, which demonstrates that the
formations of these mines are of the Eocene age.
The outcropping rocks belonging to the Middle
Neocene formations are principally sandstones with a
little shale and conglomerate, the prevailing dip be-
ing about N. 70° E. Several brine and sulphur springs
issue from this formation, and at one point there is a
spring of tar-like oil. In 1893 the writer visited the
San Joaquin coal mine (one of the old coal mines in
this locality) and saw a small quantity of oil of medium
gravity baled from one of the workings. There are
no productive wells in the Alcalde district, but in
August, 1900, ten prospect wells had been, or were
being, drilled.
Atomic Weights of the Elements.
The special committee appointed by the German
Chemical Society for the establishment of the atomic

mously recommended the following. The weights
adopted differ somewhat from those recommended by
Dr. F. W. Clarke in this country :

Yttrium Y. 89.0 89.02
Zinc Zn. 65.4 65.41
Zirconium Zr. 90.6 90.40
If hydrogen is taken as unity these weights have
values different from the above, as, for instance, oxy-
gen then becomes 15.88, carbon 11.92, iron 55.60, etc.
For refined calculutions it is best to adopt the
weights as recalculated by Dr. Clarke, but for all
ordinary purposes the weights as given by the com-
mittee of the German Chemical Society can be used.
Where large contracts are based on percentages of
certain ingredients — as, for instance, chrome ore on
the amount of acid, iron ore on the amount of metal-
lic iron and the freedom from phosphorus, etc. — it is
best to use the Clarke weights.
Direct-Acting Hoists.
In Colorado, California, Montana, Michigan and
elsewhere the direct-acting or first-motion hoist is
coming into use in many places where a high hoisting
speed is required because of the depth of the shaft,
or the magnitude of the output, the drum being
mounted on the engine shaft, the latter being extra

heavy to withstand the strain. The hoisting drum or
drums are either keyed to the engine or connected
thereto by clutches. An illustration of a single-drum
hoist, as furnished by the Bullock Mfg. Co., 1170
W. Lake St. , Chicago, appears herewith. This hoist
may be arranged with the drum keyed to shaft and
reversible engines, or with the drum loose on shaft
and a band-friction clutch for driving. In this case
the engine runs in one direction all the time, con-
trolled by the governor and throttle. For hoisting,
the clutch is tightened, connecting the drum with the
driver; for lowering, the clutch is loose and the rope
runs out, controlled by the brake. The hoists, as a
rule, are supplied with steam and hand brake; steam
reverse and steam clutch all operated from a raised
platform.

Thomas Couch of Montana and Cali-

from examining mining property in Trinity
and Humboldt counties, Cal. He says the
properties themselves are all right, but
they are almost inaccessible, and that
while he is tolerably familiar with bad
roads he never saw such poor apologies
for roads anywhere as on his recent trip,
and that while the lower Trinity region is
rich iu mineral wealth its inaccessibility is
a serious drawback to its development.
H. C. Hoover left San Francisco this
week on his return to China, where he has
charge of some mining operations. He
says that it is not because of any supersti-
tion that Chinese are averse to English or
American or German mine operators: he
says they fully understand and appreciate
the value of their mines, but want to keep
the product for themselves; and that, as
a matter of fact, the Chinese were mining
in King Solomon's time and before that
as far back as in the reign of Emperor Yu,
about 2500 B. C, when commissioners
were appointed to examine the mining re-
sources of the country in gold, silver and
cinnabar. Doubtless in those days. 4400
years ago, those mining commissioners '
were classed as mining experts, and prob-
ably gave testimony as to extralateral
rights, side lines, end lines, etc. Mr.
Hoover says throughout the northern
Chinese provinces are found everywhere
little mounds which when being uncovered
are found to be debris of ancient mines,
which went down on the oxidized ore till
sulphurets or water were encountered,
when the operations stopped. He thinks
the Chinese a probable field for the Ameri-
can mining engineer, but not an imme-
diately available proposition.
X. W. Beecher of Sydney, Australia,
wholesale hardware merchant and im-
porter of iron and steel supplies and j
tools, says that since the establishment of
the steamship line direct from San Fran-
cisco to Sydney American products are !
fast finding a market in Australia, and in
some instances they have crowded out
English-made goods entirely. " We have
begun to irrigate arid land by means of
artesian wells, the casing for which is
nearly all being purchased in the United
States. We are also buying gold mining
machinery and general hardware here."

Train Lighting From Car Axle.
Electricity has added much to the comfort, convenience and safety of modern
railway travel. Among such latest contributions is a system of lighting by
which each' car in a train has its own independent lighting apparatus. A
dynamo is placed beneath each car and the rotation of the car axle supplies
light. The dynamo is so adjusted that at a speed of fifteen miles an hour it
feeds the lamps direct, the superfluous current being stored in a battery for use
when the car is stationary. The dynamo maintains a
pressure of from thirty-two to forty volts, and is auto-
matically switched into circuit when the speed of the
train is fifteen miles an hour, the pressure being so con-
trolled that at all speeds the current supplied to the
lamps is uniform. When the car is at rest, and the switch
box has switched the dynamo out of circuit, the lights are
supplied at thirty volts by the storage batteries. After
starting, as the car gains speed the dynamo voltage is
built up until it has reached a potential above that of
the storage battery and the lamps. The latter are pre-
vented from receiving more than thirty volts by means
of resistance in their circuit. The lamps are of sixteen
candle power ; the filament is a short, stumpy one, not
affected by vibration and consequently long lived.
In transmitting the power from the car axle to
the dynamo a flexible frictional gearing is used. In the
use of a dynamo in connection with a storage battery the
polarity of the dynamo must always correspond with the
polarity of the battery. To keep the polarity of the
dynamo uniform with the batteries a mechanical device
is used, actuated by the armature shaft, which operates
to throw a switch when a change in the direction of the
movement of the car takes place.
The control of the dynamo at all speeds, so that at
a high speed the current will remain normal, is accom-
plished by the use of a small motor that operates when
the dynamo is generating, and, with suitable mechanism,
throws resistance in and out of the field coils of the dy-
namo as the speed increases or diminishes. When the dynamo is charging the
storage battery the electromotive force of the battery raises, so that without
some method of control the electromotive force would be too high on the lamps.
This system maintains a constant electromotive force on the lamps by means of
a resistance thrown in the lamp circuit in proportion to the amount of current
generated in the machine. The accompanying engraving illustrates and ex-
plains the operation. The system is supplied by the Consolidated Lighting &
Equipment Co., 120 Liberty St., New York City.

Contemporaneous comment on the remarkable
closeness in the bids on a recent big contract sees in
such evidence of collusion and an understanding be-
tween the bidders. It does not seem so to us. Know-
ing that the bids were put in under every condition
of genuine competition the incident from our stand-
point affords illustration of the exactitude now
reached in great manufacturing establishments, and
the precise knowledge that enables such concerns to
figure so closely on every detail of a large contract,
so that when the aggregate of each bid is published
the proffers vary very little. In a recent bid for
installation of a municipal electric light plant three
electrical concerns, each desirous of getting the
work, and in genuine competition, bid as follows :
$36,031, $35,874.05, $36,865. Under such circum-
stances the closeness of the bids indicates entire ab-
sence of guesswork and exact and detailed knowledge
on the part of the bidders of the cost of every item
in the proposed work.
It is not fair, as an Eastern exchange of some
standing does this week, to so strongly condemn the
mining stock exchanges, or to single out for particu-
lar denunciation the bear therein. The effort of the
bear to depress prices for the purpose of making
money on the decline, is no less reprehensible than
the effort of the bull to inflate them that he may
make money on the rise. But if the manipulations
of both the bulls and the bears were eliminated from
any mining stock exchange it would be lifeless. It is
within the limits of argument to admit that the death
of a mining stock exchange would not wholly dis-
courage legitimate mining, but yet, mining stock in-
vestments constitute a certain form of mining, for
the buyer of such stocks becomes an owner in the
property. It was because of such buying and selling
that the biggest and boldest mining development in
this country up to that time ever became a possi-
bility. We refer to the Comstock, Nevada, in its
bonanza days. Anything that will encourage legiti-
mate mining should be encouraged; anything which
tends to discourage it should be discouraged by min-
ing men; but till it is made clear to us that the buying
and selling of stock in other business combinations is
all right, while such buying and selling of mining
stock is all wrong, we fail to find the fine distinction
that commends trading in industrials, but condemns
trading in stocks of equal value and greater possi-
bilities of profit just because they happen to be
mining stocks.
Treatment of Silver-Lead Ores.
In the issue of the 17th ult. was given some discus-
sion of the concentration of silver-lead ores in answer
to a question from a Colorado miner, who wrote say-
ing : "The ore is galena, carrying gray copper,
which in turn seems to carry the silver. The gangue
matter is heavy spar, or barytes. Analysis shows
the ore to run : Silver, 19 ounces ; lead, 13.7% ; sil-
ica, 43.9 ; BaS04, 23.9. In order to effect separation
from the barytes we have found it necessary to grind
to 40 mesh. By doing this and concentrating at the
rate of 4.25 to 1 we save 99% of the lead, but our
tailings assay 17.50 ounces silver. The gray copper
and the barytes seem to pass off together. Our
neighbors, who have quartz instead of barytes, have
the same difficulty in attempting to save the silver."
Like so many other metallurgical matters dis-
cussed herein, the problem proffered and the answer
thereto have been the subject of several letters, and
the way the matter is so discussed is illustrative of
how those things appear from different points of
view. Three of the letters take the subject up in an
off-hand way and airily dispose of it as a small ques-
tion easily answered. Those letters are apparently
from men who believe what they say, but who have
not given the subject much consideration.
Noticeably different is the style of comment from
men who have made such things the study of their
lives. One Colorado miner of prominence, who has
grown gray in the practical consideration of such
questions, writes from the standpoint of intelligent
experience as follows :
" It is very rare indeed that one gets an ore that
can be perfectly treated on the ground by one class
of treatment. More particularly is this true in con-
centration. It seems as though the only all around
process is that by smelting. No matter how perfect
a sulphide an ore may appear to be, I have rarely
seen an ore that had not been subject to slight oxida-
tion, and, unfortunately, it seems to be the rule that
silver will oxidize a little quicker than any other
metal. We know that if zinc and lead are placed
together, subject to oxidizing influences, the zinc will
oxidize before the galena does. The silver in the ore
goes into so many forms that are partially or en-
tirely soluble in water, even in the ores, that seem as
though they were ideal for concentration. Of course,
we all know that a carbonate and an oxide are very
difficult to concentrate and save the values, and, of
course, a chloride is practically impossible. I have
found some difficulty in making tests on many gold
ores. Up to 60% the saving is very close indeed,
and beyond that you have to fight it for each per
cent. Very often in such cases I have found that the
ores carry tellurides of silver and gold, and this un-
doubtedly accounts for the loss.
" As an instance, I express to you a shovel used in
one of the mills here in every day work for shoveling
concentrates. You will find, first, that the iron has
been replaced by the lead, and then the lead and iron
are both being gradually replaced by silver. This is
true not alone of this one shovel, but is true of all
those that we ever used, and our ore is in many re-
spects a very excellent concentrating ore.
"The general rule when a man makes heavy losses
is to explain everything by saying, ' Oh, that goes off
in the slimes; can't be saved.' It is a very serious
question with me whether that is true or not, and in
some instances I absolutely know that it is not true.
"The silver, through this partial oxidation caused
by air and water, or by some acid in the ore, abso-
lutely goes into solution in the water.
"The first question, when a double treatment is
spoken of, that is usually asked is : ' Well, why not
concentrate first and then cyanide or chlorinate the
material that carries the values ? ' I think that in
certain instances this might be advisable, but if even
part of that stated above is true it is not always
advisable. In fact, the more I test ores the more I
find that each one must be handled separately. Of
course, the ore that your Colorado correspondent
describes is theoretically a smelting ore, but I can
readily understand that under certain conditions,
such as distance from market and other things that
might influence one, the ore would be worthless un-
less it could be treated upon the ground, and I
believe that in such cases a double treatment is nec-
essary. Whether it be by cyaniding or any other
similar agent, selective in its action upon the pre-
cious metals before concentration, or by some other
method of chlorination or pan amalgamation after
concentration, is a matter that can only be deter-
mined by actual experiment with each ore. Almost
invariably in concentration the greatest loss occurs
not in the coarse tailings, but in the dirty water that
is constantly flowing and apparently should have no
values in it. This is where the great loss is occa-
sioned. It is to take out this loss that, where pos-
sible, I would recommend some treatment before con-
centration. I have never yet seen the record kept
of a concentrator in which the losses of silver or gold
were not greater than the loss of the base mineral in
which it was supposed to be. But this is arguing in
a circle, as we go back to the first proposition.
"When we run across such propositions as this in
mining — and they occur very frequently, sometimes
in such a degree as to render worthless any particu-
lar kind of treatment, and at other times it being
only a case of percentages, but not interfering with
the commercial application of a process — it is then
that we realize how very crude are our efforts and
how much the future has in store in the study of this
and similar problems.
" In writing you this I am not at all satisfied. I
could give instances that have occurred in my expe-
rience, and I could prove the problem both ways to
any one's satisfaction, both negatively and positively.
I think if a man will study long enough on the sub-
ject of reduction of ores that in a short time his
friends will find him talking to himself on the street.
After all, these problems have to be, fortunately,
decided commercially, and not scientifically ; so, if we
make a commercial improvement we can congratu-
late ourselves, whereas if we are obliged to make a
scientific success, in many cases we would have to
confess to utter failure."
The last two paragraphs are particularly illustra-
tive of the fact so often noted by the most experi-
enced in this business, that the most one can learn is
to find how little, after all, he really knows of a sub-
ject to which he may have given years of patient,
practical work — work that, too, may have been com-
mercially successful, but from a scientific or even
technical standpoint productive of satisfactory re-
sults only in a rudimentary way.
Ore Rates in Colorado.
Next month the Transmississippi freight bureau
meets at Milwaukee, and, under the head of " unfin-
ished business," takes up a matter of moment to the
miners of Colorado. At the Denver meeting of the
bureau last September was discussed the question
of restoring the standard rate on low-grade ore,
which was reduced three years ago. The matter was
left for final settlement at the January meeting in
Milwaukee. Colorado railroad men have all along
rightly ruled in favor of the miner, purely as a busi-
ness proposition for themselves, for, unlike the Cali-
fornia rule of "all the traffic will bear," the Colorado
railroads realize that the way to build up profitable
and permanent business is to put the ore rate at
a point that will give profit with promise of
increase in amount, rather than restrict ore ship-
ments by exorbitant rates. Colorado railroads have
had much to do with the mineral development of
Colorado. In continuance of such fostering policy
they should stand as a unit at the Milwaukee meeting
next month against the proposed increase. If they
do, they will win. The increase would injure Colo-
rado's mining industry by tending to close mines and
restricting small mine operators in their shipments.
Local business between mining camps and smelters
should not be ignored, nor overshadowed by consid-
eration of " through traffic. " The Colorado miners
are not asking any favors in this thing. They recog-
nize the friendly attitude of the railroads and suggest
as a business proposition that the railroads will best
serve their own interests by according their local
patrons all possible facilities. This is a matter that
affects the business of thousands in and out of Colo-
rado who furnish machinery and supplies, and who
are thus almost equally interested in seeing that the
proposed restoration of the old rates shall not be.
For the forty-first time the Mining and Scientific
Press cordially wishes its readers everywhere ' ' A
Merry Christmas."

To drill a hole in glass with an ordinary drill it is
only necessary to keep the spot moistened with a mixture
composed of twenty-five parts oxalic acid and twelve parts

IN a cur 10$ feet long, <M feet wide and 15 inches high
there are 59 cubic feet space. A gangway 8 feet wide at

The Overland Monthly and the Journal of Electricity,
both of San Francisco, in their November issues give
excellent illustrated descriptions of the electric installa-

Bessemerizing copper matte for refining was first
used in this country at the smelter of the Parrott Co.,
Butte, Mont., and now almost entirely supersedes the re-

The Guanajuato Con. M. &M. Co. 's properties were de-

The office of the company is in New York City.
The primary function of a lubricant is to reduce fric-
tion and wear to a minimum. Friction is expensive, and
the cost of a lubricant is of secondary importance to its
friction-reducing power. The best is the cheapest.
Concrete has been used for lining mine shafts in
Belgium and elsewhere in Europe. The cement used was
made from blast furnace slag and sandstone. It con-
sisted of 55% sandstone, 12.5% cement and 32.5% broken
slag.
The degree of heat at which scale forms and adheres
to steel — that is, does not fall away from the piece when
allowed to cool in air — is about 1550° F. It is then a
light cherry red; it is yellow at 1825° and at 2200° is
white.
ABOUT the best thing to use in tempering drills is a
little borax. Wet the tool and sprinkle it on or, if hot,
dip the tool into pulverized borax ; then heat until the
borax flows, and this will be at so low a. heat that but a
dark red can he seen ; then chill.
A SUMP 12 feet in diameter, 25 feet deep, full of water
to the top, and water flowing into it at the rate of twenty
gallons per minute, would be unwatered in 1J hours by
a pump with a 7-inch end and 14-inch stroke, making
seventy-five double strokes per minute, the efficiency of
the pump being 72%.
The only known method of producing auric chloride
perfectly free from acid salt is to decompose aurous chlo-
ride with water. When gold is heated in chlorine at
atmospheric pressure, trichloride of gold is formed and
volatilized at all temperatures above 180° C, up to and
probably beyond 1110° C.
A blast FURNACE which captures and controls the
smoke from its charcoal pits, conveying it into stills,
would find that an important factor in economy. Each
cord of wood contains 28, 000 cubic feet of smoke, suscep-
tible of producing 120 pounds acetate of lime, two gallons
alcohol and one-quarter pound tar.
Liquid hydrogen is a limpid fluid, clear as water,
but of ,l, as much specific gravity, so that cork sinks in
it as lead in water. It is intensely cold, having four
times the frigorific potency of liquid air. Atmospheric
air freezes and sinks in it. Liquid hydrogen makes so
perfect a vacuum that the electric spark will not pass
through.
All exhibitors at Paris that have received awards,
whether grand prizes, gold, silver or bronze medals, will
receive with the diploma a bronze copy of the medal.
Exhibitors who obtained an honorable mention will
receive the diploma only. Gold or silver medals will be
struck for those entitled to them by the Paris mint at
cost price.
The metric system was legalized in the United States
in 1866, but its use is not obligatory. A bill is now be-
fore Congress prescribing that from January 1, 1902, the
metric system of weights and measures shall be the
standard in the United States. Public inertia defers the
adoption of the system, though its general use is inevi-
table, it being the most accurate, the simplest and the
best.
It would be a mistake for Colorado or any other State
"to use convict labor in developing mineral lands be-
longing to the State, " as it would tend to degrade the
miner. For centuries the miner was so degraded, and
now that in later years he stands erect and assumes the
godliko attitude of freedom and a man, it would ill be-
come an American commonwealth to delegate the work
of developing its mining resources to convict labor.
At the Cariboo mill, Camp McKinney, B. C, theplutes
are dressed four times every twenty-four hours with a
very dilute solution of potassium cyanide and sal ammo-
niac. The outside plates are scraped every second day,
and a full clean-up is made twice a month. Of the total
amalgam 68% is saved inside the battery, l.'l% on the lip
plates, and 19% on the apron plates. The amalgam con-
tains 30% bullion, and the bullion has a fineness of .670
gold.
There are honest men manufacturing gas engines,
just the same as other machinery, and they can be relied
upon to tell a prospective buyer whether or not a gas
engine is suitable for his particular neod. The gas ongine
manufacturer who understands his business will be able
to give some valuable pointers to a possible customer if
the latter describes his individual requirements; and if a
gas engine is not suitable the gas engine manufacturer
would find it better business to tell him so at the start
than to make a failure of an installation because of un-
toward conditions.
Although anhydrous tungstic acid is soluble in
water, especially when hot, yet it is scarcely at all solu-
ble in water which contains any portion of acid. It
appears to be insoluble in all acids except in hydrochloric
and hydrofluoric acids, in which it is very sparingly sol-
uble. Consequently, a dilute solution of hydrofluoric
acid will not dissolve tungstic acid readily, if at all. A
solution of tungstic acid in hydrofluoric acid would prob-
ably be yellow. Tungstic acid is more soluble in a hot
solution of any alkali than in a cold one, but heat is not
absolutely necessary to cause the solution.
One economical method of distributing electricity
through a town would bo to place dynamos and gas
engines at substations and utilize the gas from the street
mains for driving purposes. Such a scheme has much
to recommend it, but it is doubtful whether any gas com-
pany would appreciate it sufficiently to bring down the
price of gas to a point at which the experiment could be
tried. There was a time when gas companies, by adopt-
ing some such policy, could have controlled the future of
electricity supply ; they missed their opportunity and
have had to face a competition, which, with the appar-
ently limitless possibilities before electricity, is bound to
become more severe from year to year.
The Johnson pneumatic cyanide process consists in
expressing the water out of the slimes obtained from the
mills by means of a filter press, displacing the moisture
and soluble cyanocides in the filter cakes formed in the
press by cyanide or potassium solution. The press is
opened and the cakes of slimes dropped into a vortex
mixing vat containing cyanide of potassium solution,
which is arranged so that air can be drawn into the vor-
tex, facilitating the working of the cyanide. After the
proper amount of cake and cyanide solution have been
placed into the mixing vat. the agitator having been pre-
viously set in motion, the gold is brought into solution.
The slimes are passed through a valve into a second re-
ceiver and forced into the leaching press. The gold
leaves this press in solution and is run over boxes con-
taining fine zinc, precipitating the gold in a metallic
form. The cyanide containing gold that may be left in
the filter cakes is displaced by pure water.
A pew miles from Pittsburg, Pa., a well has been
dug 5532 feet deep. Near Wheeling, W. Va., a well is
4920 feet deep. At Sperenherg, near Berlin, Germany, a
hole in gypsum beds is 4559 feet deep. At Schladebach,
near Leipsic, salt is taken from a well 6265 feet deep.
The Red Jacket shaft of the Calumet & Hecla mine, in
the Lake Superior copper district, is a mile deep, and
men work in the shaft. Near by, the Tamarack mine
has a shaft nearly as deep as the Red Jacket. At
Paruschowitz, in Eastern Silesia, there is a well 6700 feet
deep. They are still boring; it is the intention to go
down 8800 feet. This last is now the deepest artificial
hole in the world. At Lieth, near Altona, Germany,
there is a hole 4388 feet deep; at Eu, near Strassfurt, is
one 4241 feet; at Lubtheen, Mecklenburg, one 3949 feet;
at Sennewitz, near Halle, 3644 feet has been reached; at
Inowrazlaw, Posen, drills are working at 3624 feet; at
Friedrichsane, near Aschersleben, a well is 3543 feet
deep. At St. Louis, Mo., is a well 3843 feet deep. Many
buildings in several parts of the world are heated with
naturally warm well water; the hospital at Grenelle and
large factories in Wurtemberg are examples.
Gold scrap containing platinum is kept apart for sep-
arate treatment in minting, as the ordinary methods of
refining gold would not be suitable for it. In dealing
with a large batch of metal, the sifted filings are digested
with nitric acid of specific gravity 1.199 as long as any sil-
ver dissolved, a trifling amount of platinum also dissolv-
ing as silver platino-nitrite. The metal remaining is
weighed and washed with aqua regia, until the silver
chloride forming on the surface of the metal prevents
further action. The solution of gold is then poured off
and the silver chloride removed by treatment with dilute
ammonia, when the metal is again in a condition for
further treatment with aqua regia. After six alternate
treatments with aqua regia and ammonia, the residual
metal consists oi pure platinum. The acid solution con-
taining the gold is evaporated with oxcobs of hydro-
chloric acid to drive off nitric acid, until gold chloride
crystallizes out. This is then dissolved, and a small
amount of platinum removed by adding ammonium
chloride, the gold finally precipitated by ferroussulphate.
In onosuch operation the filings contained 28. 05% of gold,
10.56% of silver, 45.46% of platinum and 15.93% of cop-
per. If tho metals are really alloyed, it is necessary to
fuse with three parts of lead, or, better, of zinc. After
granulating the melt, it is easy to remove the zinc by
treatment with sulphuric acid, the gold, silver and
platinum remaining in a finely divided form suitable for
separation by the method already described.
Records of mining locations must contain the name
or names of locators, the date of location, and such a
description of the claim or claims located, by reference
to some natural object or permanent monument, as will
identify the claim. No lode claim can be legally located
until after the discovery of a vein or lode within the
limits of the claim. The object of this provision is to
prevent the appropriation of presumed mineral ground
for speculative purposes to the exclusion of bona fide
prospectors, before sufficient work has been done to de-
termine whether a vein or lode really exists. The claim-
ant should, therefore, prior to locating his claim, unless
the vein can be traced upon the surface, sink a shaft, or
run a tunnel or drift, to a sufficient depth therein to dis-
cover and develop a mineral-bearing vein, lode or crevice;
should determine, if possible, the general course of such
vein in either direction from the point of discovery, by
which direction he will be governed in marking the
boundaries of his claim on the Burface. His location no-
tice should give the course and distance as nearly as
practicable from the discovery shaft on the claim to some
permanent, well-known points or objects, such, for in-
stance, as stone monuments, blazed trees, confluence of
streams, point of intersection of well-known gulches,
ravines, or roads, prominent buttes, hills, etc., which
may be in the immediate vicinity, and which will serve
to perpetuate and fix the locus of the claim and render
it susceptible of identification from the description
thereof given in the record of locations in the district,
and should be duly recorded. In addition to the forego-
ing data, the claimant should state the names of adjoin-
ing claims, or, if none adjoin, the relative positions of the
nearest claims; should drive a post or erect a monument
of stones at each corner of his surface ground, and at
the point of discovery or discovery shaft should fix a
post, stake or board, upon which should be designated
the name of the lode, the name or names of the locators,
the number of feet claimed, and in which direction from
the point of discovery ; it being essential that the loca-
tion notice filed for record, in addition to the foregoing
description, should state whether the entire claim of
1500 feet is taken on one side of the point of discovery,
or whether it is partly upon one partly upon the other
side thereof, and in the latter case, how many feet are
claimed upon each side of such discovery point. The lo-
cation notice must be filed for record in all respects as
required by the State or Territorial laws and local rules
and regulations, if there be any.
The substance of the grant made by the Government
to the locator of a lode claim is the mineral deposit be-
neath the surface. Prior to the extraction of the ores,
the extent of the deposit to be conveyed can be measured
or defined only by surface survey lines, through which
imaginary planes are drawn. Such survey lines do not
invade the right of exclusive possession and enjoyment
of the surface granted by statute to the senior propri-
etor. Such lines occupy the actual surface space o;
length or breadth. They are, however, the only prac-
ticable means of marking the section of the lode claimed
by the junior locator. They mark the exterior bound-
aries, within which the rights of the junior locator are
confined. The extent of his rights within these exterior
boundaries is readily ascertained by excluding from the
whole that which has already been granted or reserved
to others. By this process no right of the senior locator
is invaded. By no other process can the junior locator
obtain what the law offers him. Therefore, the lines of
a junior lode location may be laid upon or across the sur-
face of a valid senior location for the purpose of defining
for, or securing to, such junior location underground or
extralateral rights not in conflict with any rights of the
senior location. The term is not applied to the surface
boundaries of portions of a claim which may be patented
to different parties. The end lines are voluntary end
lines, fixed by the locator of the claim. They are not the
lines fixed by an adverse claimant to mark a different
and conflicting claim. It will therefore be seen that,
while, at the surface, one has the right to but a small
portion of the vein, as the end lines of the conflicting
claims diverge, he upon gaining depth is constantly in-
creasing the length of vein upon which he has the right
to work until when the points are reached at which the
planes of the conflicting end lines intersect, he gets the
full 1500 feet along the course of the vein. In such a
case as this, if the law confined the claimant to the in-
terior of vertical extensions of the side lines, there would
be little object in taking up the end lines of contiguous
claims, as there would be not enough to warrant the ex-
pense of opening the property, unless the vein should be
very rich, while an outside locator on the dip of the vein
could take advantage of his knowledge of the situation
and secure rights to a vein passing through his prop-
erty, indeed, but which he had never discovered at all,
and this would conflict with the intent of the law which
was to reward the discoverer; and as discoveries are al-
most invariably made upon the apex, it does this by giv-
ing to the owner of the apex the ownership of the vein
to any depth.

Consolidations in Gilpin County, Colo.
The accompanying illustrations on this and the
frontpage pertain to present mining and milling op-
erations at Black Hawk, Gilpin county, Colo., encom-
passing the ground whereon John Gregory in 1859
made the initial discovery of a gold-bearing lode in
this State. It is historic ground, for it not only marks
gineer, and the ready co-operation of Boston and
other Eastern capitalists. With the idea of central-
izing operations, the extensive developments under-
ground during the last two years have been so planned
as to bring the ore from the various bodies to a com-
mon center on each level and ship it out through a
main channel. The Cook shaft, 900 feet depth, which
is now the center of operations, sinks at a point near
the intersection of the main north and south lode with
the two main east and west parallel lodes ; so that

the first opening of a fissure vein, but the operation
of the first stamp mill and, farther down Clear creek,
the first smelter in Colorado. Black Hawk and
Gregory hill are, in Colorado history, what Sutter's
creek is in that of California. When the gold seeker
and adventurer started from the Eastern and Middle
States in 1859 and 1860 with
wagons adorned with " Pike's
Peak or Bust," their real destina-
tion was not Pike's Peak, but
Gilpin county, whose creek sands
carried free gold and whose moun-
tain fissures held paystreaks. The
vast ledges of gold-bearing ore
which actually did exist in the hills
contiguous to Pike's Peak were
reserved by destiny till 1892, when
the name of Cripple Creek was
cautiously announced to a waiting
world.
The discovery of the Gregory
lode, the news of which rapidly
spread, attracted much interest,
Horace Greeley, editor of the
New York Tribune, verifying the
news by a personal visit to the pro-
perty in June, 1859. As exploita-
tion and development progressed
on Gregory and Bobtail hills, other
fissures were opened, principal
among which were the Fisk, Bob-
tail, Mammoth and Cook, and
these, with the Gregory, have
formed the basis of operations
ever since, though until recent
years under several distinct own-
erships and separate manage-
ments. Development on these lodes
to the extent of nearly 25 miles of
underground workings from the
date of the discovery to the pres-
ent time, the steady production
throughout that period, and the
extent of ore bodies exposed by
more recent and deeper workings,
give some conception of the life of
a group of mines on such well
marked fissures.
Formerly the Gregory-Bobtail,
Fisk and Cook each operated with
a separate plant of hoisting, pump-
ing and compressor equipment, but
whose workings became connected
at various points. Within the last
four years various consolidations
and purchases have been effected
whereby the three main groups, with other con-
tiguous ground, all aggregating sixty-seven pat-
ented claims, have been brought into one consoli-
dation, under the proprietorship of the Boston & Den-
ver Consolidated Mines & Milling Co. This has been
accomplished under the financial management of Mel-
vin P. Dalton, with Clarence K. Colvin as mining en-
very little dead work has been necessary to reach the
ore bodies in any part of the group from this shaft.
The latter is three-compartment, well timbered, with
two cages operated by a gear and friction hoist, pre-
viously described in these columns. Within the shaft
house are the boilers and two4-drill compressors. At
horizontal plane. The most aggressive work now is
on the Mammoth vein on the sixth and seventh. In
the stope above the sixth, on this vein, I saw five
Sullivan air drills at work breaking down ore ; one
drill was drifting on the sixth. Similar work was in
progress on the west end of the seventh level on the
Mammoth and the east end of Fisk. For a distance
of 150 feet this vein is stoped out between the sixth
and seventh, showing the material between walls was
12 to 20 feet wide. On the west end of the Maverick
vein were ten men with hand drills stoping above the
seventh. On the eighth level the work of drifting
west on the Mammoth and east on the Bobtail was in
progress. The plan of work in this mine is to drift
on the vein on each level, stull overhead and put in
chutes every 20 feet ; then stope up to next level,
letting the broken ore pile up on the stulls as the
work proceeds, about one-third of it being drawn
through the chutes and hoisted to make room for the
work. About 4 feet of solid ground is left at the bot-
tom of each drift. When the stoping is completed to
the level above, the broken ore is then drawn out
through the chutes for shipment as fast as required.
In one stope there are now at least 5000 tons of ore
on the stulls and as much more in other stopes. The
almost total absence of waste material between the
vein walls makes this method feasible, and it reduces
the necessity for timber. The Mammoth vein will
average 12 feet wide on the sixth and seventh levels.
It swells to 30 feet in places and narrows to 6 feet in
others. The Bobtail vein averages 4 feet wide, the
Maverick 5i, the Cook 5 the Fisk 4 and the Gregory
5 feet.
The ores in general are a copper and iron sulphide,
with streaks of quartz that carry free gold. There
are no oxidized ores at present working depths. At
the crushing floor of the mill the smelting grades are
sorted out ; this amounts to about twelve tons per
day, the milling ore amounting to 300 tons per 24
hours. The smelting ore will carry about 31% silica,
the mill concentrates 10%.
The mill, equipped with Blake crushers, eighty
rapid-drop, 1000-pound stamps, amalgamating plates,
and twenty-four Woodbury concentrators, was
erected by the Hendrie & Bolthoff Mfg. & Supply
Co., and was illustrated and fully described in the
issue of this paper of July 14, 1900. It has been in
operation several months, and every feature appears
to do very satisfactory work, the concentrate prod-
uct amounting to seventy tons per day.
The ore car line, 4250 feet long, which extends from
the crushing floor of the mill to the 360-foot station
of the Cook shaft, first runs 600 feet above ground,

the 360-foot level is the loading station, where cars of
ore are landed from any level in the mine and trans-
ferred to the tramcar track and hauled out through
the mill tunnel to the crushing floor of the mill, 4250
feet distant. On the group there are about 15 miles
of drifting on the veins; on either the sixth or seventh
levels may be seen 11,000 feet of work in ore on a
thence through 1280 feet of tunnel under Bates hill,
thence 400 feet on surface in crossing Gregory gulch,
thence through about 2000 feet of the old Bobtail tun-
nel to loading station at the shaft. The track is 24-
inch gauge, with 30- pound rails, laid on 4x6-inch cross-
bars ; it is ballasted and smooth. The four-ton,
center-dump cars, capacity four tons each, are hauled

back and forth by a Jeffrey electric locomotive, sup-
plied with power by a 67 H. P. generator in the mill,
which is transmitted over the line by an 00 wire, sus-
pended at points 25 feet apart. Three cars make up
a train, whose work runs as high as ninety- three cars,
197 tons ore, in nine hours.
Another feature of the big group is the Gregory
incline, which starts near the mill, runs at an angle
of 24° for 700 feet, thence 1343 feet farther, to the
base, at a 38° angle. At the incline's Moo-foot station
is a duplex, compound pump of 800 gallons per minute
capacity. The first 005 feet of this incline is a cross-
cut, thence on it sinks on the Gregory vein. From the
base of this incline a crosscut tunnel runs 800 feet
southward to the Fisk, thence tapping the Bobtail
lode 400 feet farther at 11-100 feet below the surface
and 000 feet east of the Cook shaft. The plan is to
sink the Cook shaft to and below the level of the
Gregory crosscut and connect the two, so as to han-
dle the ore from the Gregory and other mines on the
north side of the group, through the main shaft. At
present about sixty-five tons per day are hoisted
through the incline. In these operations there is no
shoveling of ore, it being handled by gravity, electric
haulage and automatic feeders; the concentrate prod-
uct is carried by belt conveyors from the tables to the
car on the side track. The entire property is a good
example of the economy to be effected by the consoli-
dation of mines, centralizing operations and increas-
ing the tonnage. Wascott.

"Booming" With a "Shooter."
A peculiar feature used in northern California to
assist the placer and hydraulic miner is what is
known as a "shooter." It consists of an automatic
reservoir of various sizes and shapes, that collects all
the water not run through the giants or monitors
for, say, fifteen minutes, when a valve automatically
opens of sufficient size to allow all the water thus col-
lected to escape in five minutes, thus obtaining the
use of over 20,000 inches of water for five minutes
that 2000 inches has furnished by cacheing it for
fifteen minutes; that force of water will carry boul-
ders weighing over 500 pounds through one mile of
flume in five minutes. Several hydraulic mines in
the northern counties are equipped with one of these
shooters. On the Boss & McClary placer mine,
Trinity Center, Trinity Co., the shooter box is 20x40
feet square and 6 feet, with an automatic opening of
18 inches by 4 feet. There is a bedrock flume 6 feet
wide by 3 feet deep, nearly half a mile long, lined
with 9-inch blocks.
It was in northern California that the style of hy-
draulic mining known as " booming" was first intro-
duced, and has since been most largely in use. It is
practiced only along the gulches. These affording
but little water, it became necessary that the lim-
ited supply be reservoired and properly distributed
in order to make it effective in gravel washing. The
object is attained by retaining the water in dams and
then releasing it suddenly, with a rush or boom.
Near the bottom of the dam built for this purpose is
left an aperture so large that when opened the water
escapes rapidly. Placed on the top of the structure
is a small race, through which the water flows when
the dam is full, and is discharged into a large wooden
box suspended from the end of the sweep, turning on
a pivot, and the upper end of which extends to and
over the top of the dam. Attached to this end of the
sweep is a strip of heavy canvas which, dropping in
a fold over the aperture below, keeps it tightly
closed when the dam is full. When this stage has
been reached the water flowing through the race
into the wooden box mentioned soon fills it, causing
this end of the sweep to sink and the other to rise,
carrying with it the strip of canvas and uncovering
the large aperture below, allowing the water to rush
out. Meantime, the wooden box, having emptied
itself through numerous small holes made for the
purpose, this end of the sweep, relieved by its
weight, rises, and the other end drops. The canvas
falls over the outletting aperture, closing it as be-
fore. Then the dam fills again to the brim, and the
operation as above is repeated. This plan for hand-
ling water is wholly automatic. It takes care of
itself and goes on day and night, without any atten-
tion on the part of the miner, doing its work as long
as the water lasts.
C. A. Sargent, referring to the necessities for
larger improvement in the modern gas engine, takes
up only the shortcomings of the gas engine of the
four-cycle type in which the piston acts during the
first, or forward, stroke, as a pump drawing in the
charge of air or combustible mixture; compressing it
on the second, or back stroke,- completing the first
revolution of the crank shaft; performing work dur-
ing inflammation, the forward stroke of the second
revolution and exhausting the burnt products during
the back stroke of the second revolution. He sug-
gests that if, instead of taking a cylinder full of com-
bustible mixture as the unit of a fresh charge the
engine is designed so that two-fifths or thereabouts
of a cylinder full of combustible mixture is sufficient
for the average load, there will be much greater
range in which the engine may be worked without an
appreciable loss in efficiency. As the compression
changes only one-half as fast as the cut-off, with a
change of load there will be a reserve of power, even
if the release is considerably above atmospheric pres-
sure, so long as compression does not go sufficiently
high to cause premature ignition. The quicker the
expansion of gases the more heat will be turned into
work and the less transmitted to the cylinder walls.
Therefore if the time of ignition is advanced so that
the maximum of pressure takes effect at the begin-
ning of the stroke, the piston speed may be mate-
rially increased and the jacket losses minimized.
Orthodox" and "Wild Cat'
Propositions.
Oil
In chapter 4 of Bulletin No. 19, ''Oil and Gas
Yielding Formations of California," issued by the
California State Mining Bureau, geological conditions
attendant thereon are discussed and the commercial
aspect of the problem given considerable prominence.
In instancing the fact that the financial risks of pros-
pecting for oil vary greatly, the chapter notes that
oil prospecting propositions may be divided into two
orders :
First. — The " orthodox " proposition. In this case
the prospectors have in view a definite oil yielding
stratum, which has proved remunerative in adjacent
territory, and from which stratum they expect to
obtain their oil. Moreover, they have satisfactory
geological evidence in sight that the oil stratum
they have in view forms an oil line through the terri-
tory they are about to prospect. |
Second. — The ".wild cat" proposition. In this in-
stance the prospectors have no definite oil stratum
in view which has proved remunerative in adjacent
territory, or they have not satisfactory geological
evidence in sight that an oil yielding stratum, which
is known to be productive in adjacent territory,
forms an oil line through the land they are about to
prospect.
In prospect wells of the first order the least risk
is taken where the outcrop of an oil sand, which has
proved remunerative in a certain oil field, can be
actually traced through the territory to be pros-
pected, and the geological structure of the locality is
known.
More risk, however, is undertaken where there is
no outcrop of the oil sand, although the strike and
dip of a remunerative body of oil sand in an adjacent
oil field are known, and the rocks overlying the oil
sand can be traced to the territory about to be pros-
pected. When an oil line has been developed on one
side of a fold, and an outcrop of oil sand has been dis-
covered on the other side of the fold, propositions to
prospect this side must be classed among the more
risky "orthodox" propositions.
Most oil mining enterprises which have for their
object the development of new territory, especially
when operations are conducted at a distance from
any known oil field, are "wild cat" propositions.
Some idea of the conditions regulating the amount of
risk involved in such enterprises may be gathered
from the following statements :
The least risky " wild cat " proposition is the case
in which the strike and dip of a remunerative stratum
of oil sand in adjacent territory have been ascer-
tained, and, although there is no conclusive geologi-
cal evidence in sight; it is found after carefully plat-
ting a map of the territory that, if the stratum of oil
sand were extended in the direction of its strike,
without any material alteration in the angle of its
dip, it would form an oil line across the territory to
be prospected. It is a more risky " wild cat " prop-
osition to prospect the side of a fold opposite to that
on which an oil line has been developed, in cases where
surface indications warrant the assumption that the
same sequence of formation exists on both sides of the
fold, and yet no outcrop of oil sand has been discov-
ered on the side about to be prospected.
It is a still more risky "wildcat " proposition
when a stratum of oil sand has been discovered, con-
cerning which nothing is known except that the sand
gives evidence of containing oil, and a well is sunk for
the first time to determine whether or not the oil
sand contains oil in remunerative quantities.
It is a much more risky "wild cat" proposition
where no outcrop of oil sand has been discovered, but
where a well has been sunk in a certain formation
because it shows some irregular seepages of petroleum
or because the formation appears to be similar to that
containing a remunerative body of oil sand in other
places.
It is well for oil prospectors to study the risk they
are about to take before expending money, and care
should be taken to control sufficient territory that
they may have sufficient room to develop their oil
field, in case their venture proves successful. No one
should undertake the more risky forms of prospecting
unless he can well afford to lose the money to be put
into the enterprise.
In California petroleum is found in shales, lime-
stones, sandstones and conglomerates, and in a few
instances crystalline rocks are found impregnated
with it ; but in nearly all of the productive wells the
oil is found saturating sandy strata. In this State
the folding of the rocks has brought these oil-soaked
strata near the surface, and the oil lines, or the lines
along which remunerative wells can be obtained, are
parallel to the axes of folds, or to the lines of faulting.
The oil lines extend in breadth only a certain distance
down the limbs of the folds or down the block of tilted
strata, which has been isolated by faulting. The lat-
eral extent of the oil line is limited at its upper mar-
gin by the outcrop of the oil sand, or by a line of
geological disturbance such as a fault, or by the oil
sand being brought too close to the surface at the
axis of the fold on which the oil line is situated. On
its lower margin it is limited by the dip of the forma-
tion, which carries the oil-yielding stratum to too
great a depth for it to be profitably reached by the
drill ; or, where the oil sand is struck below a certain
depth, it may be found that the water has displaced
the oil.
As geologists and oil men know, the dip and strike
of the oil sand are of the greatest importance in lo-
cating the site of an oil well, and in the case of pros-
pect wells the dip and the strike have to be ascer-
tained from the exposed rocks.
Many people are not familiar with geological terms,
therefore it is in order to describe what is meant by
the dip and strike of a stratum of rock, and to give
simple methods for determining the conditions repre-
sented by these terms.
The dip of a stratum of rock is the angle which its
surface, when inclined, makes with the horizon. The
strike is the horizontal direction in which the stratum
of rock extends, and is always at right angles to the
dip. Therefore, if the direction of the dip is known,
the strike can be readily determined.
The direction of the dip of an inclined stratum cor-
responds to a line drawn along the inclined surface in
the direction of its greatest inclination, and is always
at right angles to the strike. (See article by the
writer in Mining and Scientific Press, Feb. 4, 1899.)

Silvering Copper Plates.
There are several methods adopted in the silver
plating of copper plates. In one of these methods
the plates are silvered by painting the back of the
plate with some substance which does not readily
transmit electricity, such as paraffine, or a similar
substance, and then immersing the plate in a solution
of cyanide of silver. Such a solution may be formed
by dissolving silver cyanide in cyanide of potassium,
or it may be made up by taking a solution containing
1 part of cyanide of potassium to 10 parts of water,
adding 1 gram of silver chloride to every 150 c. c. of
the cyanide solution. The plates are immersed in
such a solution and are connected with the negative
(or zinc) pole of a galvanic battery, the positive
(copper or platinum) pole of the battery being con-
nected to a silver plate also immersed in the solution.
The current gradually decomposes the silver cyanide,
and this metal is deposited on the object connected
with the negative pole, while the cyanogen liberated
at the silver plate attacks the silver so that the so-
lution is always maintained at the same strength.
The quantity of silver dissolved from the silver plate
is exactly equal to that deposited upon the copper
plate.
A very thin silver plating can be put on copper
plates by rubbing them with a mixture of 10 parts of
silver chloride, 1 part of corrosive sublimate (mer-
curic chloride) and 10 parts of bitartrate of potash.
The silver and the mercury are both reduced to the
metallic state by the copper, and an amalgam of the
silver is formed which merely coats the surface.
The surface to be covered should, in any case, be
carefully cleaned by immersing in, or washing with,
dilute nitric acid and then washing in water. This
last named method is not much, if any, better than
the ordinary process of preparing copper plates with
mercury and sal-ammoniac.
Verdigris can be prevented by neutralizing any
acids contained in the ore with lime, or similar com-
pounds; and should spots of verdigris appear on the
plates, they should be scrubbed off with sal-ammoniac
or a little cyanide, and the spots rubbed with mer-
cury, preferably containing a small amount of amal-
gam. It is best never to use cyanide of potassium
on silver plates, as it simply dissolves some of the
silver and carries it away with the wash water.
Permanganate of potassium does not neutralize the
effect of cyanide of potassium.
The Twentieth Century's Dawn.
The first people to live in the twentieth century
will be the Friendly Islanders, for the date line, as it
may be called, lies in the Pacific ocean just to the
east of their group. At that time, although it will
be already Tuesday to them, all the rest of the world
will be enjoying some phase of Monday, the last day
of the nineteenth century (December 31, 1900). At
Melbourne, Australia, people will be going to bed,
for it will be nearly ten o'clock ; at Manila, Philippine
Islands, it will be two hours earlier in the evening ;
at Calcutta, India, the English residents will be sit-
ting at their Monday afternoon dinner, for it will be
six o'clock ; and in London the clock in the tower of
the House of Commons will be striking the hour of

Important Land Office Decision.
On the 18th inst. Land Commissioner Hermann de-
cided the case of the Kern River, Cal. , Oil Company
vs. C. W. Clark, from the Visalia, Cal., land district,
which was commonly known as the " scrippers' case,"
against Clark, defeating the claims of the scrippers.
The report is an elaborate one and will settle many
questions in addition to that which brought it before
the land office. Despite its fullness and the many de-
cisions cited in it, it is understood that S. C. Ward,
on behalf of the scrippers, will appeal to the Secre-
tary of the Interior.
Clark claimed title to a forest reservation by virtue
of two separate selections. The oil company pro-
tested that these lands were mineral, and claimed
them under mineral locations made prior to the date
of these selections. About the time these selections
were made it was represented to the land office that
the lands in this and a large number of adjoining
townships were solely valuable for their petroleum
deposits, for which they had been located under the
mining laws and for which they were being developed.
The survey of the lands over forty years ago made no
reference to minerals, and returned the lands as
agricultural, and the opinion says the lands remained
unclaimed under the agricultural laws until after
their location as mineral.
The Commissioner holds that those claiming title
to selections under the Act of June 4, 1897, have not
done all they are required to do until they have filed
proof required, made proof of the publication of no-
tice and the same has been approved by the General
Land Office.
Under this ruling the opinion says the land in these
sections is yet open to exploration under the mining
laws, and that if at this date the lands are shown to
be mineral, it defeats the selections. The opinion
says: "It does not seem that any question could
arise as to who had the best right to this land and to
whom the mineral product belongs. Even if no well
should be sunk at the date of selections and the min-
ing claimants had rested solely upon the surface dis-
coveries, but were duly proceeding with reasonable
diligence to develop the claims, the agricultural
claimants would not have been entitled to the land as
' vacant land, open to settlement.'
"If the lands are not distinctly agricultural in
character, but, in addition, contain on the surface
mineral indications justifying a discreet person to
prospect and develop the same, then the affidavit
which avers that ' the application, therefore, is not
made for the purpose of fraudulently obtaining title
to mineral land, but with the object of securing said
land for agricultural purposes, so far as the deponent
knows,' is not only evasive but misleading, and evi-
dences a motive for acquiring the lands really for
mineral and not for agricultural purposes.
"The good faith of the mineral claimants is ap-
parent and conclusive. They seek to obtain, in a
proper manner, title to lands under laws solely pro-
vided therefor. I do not find the same conditions ex-
isting in the case of the agricultural claimant, who
seeks to acquire mineral lands under agricultural
laws, the lands being admittedly mineral and not
agricultural."
From this the Commissioner deduces the following:
" At the date of these selections the lands included
therein were covered by mining claims and therefore
not vacant; that they were known to be mineral and,
therefore, were not open to settlement; that the fact
that the conditions were not on record in the Land
Office did not affect the mineral locators' rights; and
the failure of the agricultural claimant to state the
facts was a fraud on the Government and the mineral
claimants, as the selectors are charged with notice
of mineral locations. If any further evidence is
needed in support of the above conclusions it is to be
found in the special agent's report, made with refer-
ence to these particular selections, nor can there be
any question of the authority of this office to con-
sider such report in connection with the record in
this case."
In previous issues were given the details of the
consolidation of the American Smelting & Refining
Co. and the Guggenheim smelters. Official announce-
ment is made of the absorption. Stockholders of
the former company will be asked to assent to the
proposition that the capital be increased from $55,-
000,000 to $100,000,000; of this amount $15,000,000 to
be added to the working capacity of the company.
The Guggenheims receive the difference between the
$55,000,000 and $100,000,000, less the $15,000,000,
which it is proposed to utilize for extra working
capacity. None of the new stock will be offered for
sale. The stockholders of the smelting company will
hold a special meeting after Jan. 1 to ratify the
action of the directors.
Some Questions Answered.
What causes zinc shavings to hecome very brittle and
crumble to dust within a few hours after being put in the
extractor, and what remedy would you suggest '? I sup-
pose that it is sulphur in solution and I have used lead
acetate, which seems to prevent the zinc getting brittle
quite so soon.
Isabella, Cal.
It is not possible to answer this query concerning
the cause of the brittleness of the zinc without an ex-
act knowledge of the composition of the solution; but
it is probably due to cyanide of mercury in his solu-
tion. This precipitates on the zinc as zinc amalgam
and rapidly causes the zinc to become brittle. The
fact that the lead retards the brittleness seems to in-
dicate that the latter absorbs mercury and protects
the zinc to some extent. He might retort some of
the brittle zinc and see whether or no he gets mer-
cury.
* (1) If I make a mining location while in the employment
of another person or company, can my employer, by law,
claim half of said located ground, no agreement to that
effect having been made ?
In the absence of any agreement, grubstake or
otherwise, he can not.
(2) In parting my bead, why is the gold always black
before annealing?
Regarding the black color of gold upon parting
and before annealing, it is generally believed that
such gold is coated with some salts of gold that is re-
duced to metallic condition by annealing, for before
being annealed it will not amalgamate with quicksil-
ver nearly so readily.
(3) Give a method for determining the fineness of gold
bullion or dust.
Gazelle, Cal.
There is no method other than assaying to deter-
mine the actual fineness of gold.
Some time ago you published the legal code or system
of mine bell signals in use in Montana and California. Is
there not a similarly ordained set of signals legalized in
the State of Colorado, and, if so, will you state what
it is ?
Breckenridge, Colo.
A State legislative Act authorizes the Colorado
Commissioner of Mines to establish a uniform code of
signals in all mines using hoisting machinery as fol-
lows :
Signals.— 1 Bell— Hoist. (See Rule 2.)
1 Bell — Stop, if in motion.
2 Bells— Lower. (See Rule 2.)
3 Bells — Men on, run slow. (See Rule 2.)
7 Bells — Accident. Hoist or lower by verbal or-
ders only.
3-2-1 Bells— Ready to shoot. (See Rule 3.)
Engineer's Signal. — Engineers shall after signal
3-2-1 raise the bucket or cage 2 feet and lower again,
and shall remain at his post until final signal is given
and command executed.
Rules Governing Signals. — Rule 1. — In giving
ordinary signals make strokes on bell at regular in-
tervals. In signals similar to "Ready to shoot"
(3-2-1 bells) each bar (-) must take the same time as
one stroke of the bell.
Rule 2. — When men are to be hoisted or lowered,
give the signal for "Men on; run slow," (3 bells).
Men must then get on bucket or cage, then give sig-
nal to hoist or lower (1 or 2 bells).
Rule 3. — After signal "Ready to shoot" (3-2-1
bells), engineer must give signal that he is ready to
hoist by raising and lowering bucket 2 feet. Miners
must then give the signal "Men on" (3 bells), then
" spit fuse " get on bucket or cage and give signal
to hoist.
Rule 4. — All timbers, tools, etc., longer than the
depth of bucket, or placed within a cage, must be
securely lashed before being hoisted or lowered.
Rule 5. — Signals to meet local demands and not in
conflict with above may be added by individual oper-
ators, but the same must be posted in clear and legi-
ble form in connection with above code.
Please give in "Concentrates " a formula for the
preparation of cadmium boro-tungstate.
Spokane, Wash.
After two weeks' effort, it is not found possible to
answer this question.
Suppose a man has a group of adjoining and intersect-
ing claims, and by driving a tunnel he can develop all of
them; can he do all the required assessment work by
running such tunnel ?
Telluride, Colo.
Certainly; if he can prove the above statement and
does $100 worth of work for each claim in the manner
specified — that is, suppose the Telluride inquirer has
six such claims; by doing $600 worth of work in the
tunnel he does the required annual assessment work
for the whole six; if he have eight claims, $800, and
so on. But, in Colorado, he must, to make matters
sure, do more. He must " erect a substantial post,
board or monument at the mouth of the tunnel, upon
which should be posted a notice giving the names of
the parties or company claiming the tunnel right;
the actual or proposed course or direction of the
tunnel; the height and width thereof and the course
and distance from the face or point of commencement
to some permanent well-known object in the vicinity."
Then our Telluride inquirer should make a copy of all
this and file it with the clerk and recorder of San
Miguel county.
State in "Concentrates " how to locate a mill site and
a water right on the same site. The mine is not con-
tiguous thereto, but near by.
Morenci, Arizona.
Section 2337 U. S. Revised Statutes gives the re-
quired method of securing a mill site. A water right
upon the public domain can not be acquired under the
mill site laws.
Please answer in "Concentrates": A located a min-
ing claim in 1893; B made a location in 1894 and over-
lapped A's ground; A and B filed their notices for record;
C made a location on the ground originally held by A
after A forfeited his original rights for not doing the
annual assessment work. Which one is entitled to the
ground originally held by A ?
Eureka, Utah.
C has a right to that portion of A's original loca-
tion not in conflict with B's location.
Through A's patented placer claim runs a creek. A
has not located the water and does not use it. Can B lo-
cate the water on A's ground and pipe it over A's ground
to B's ground and use it for mining purposes ?
Newsome, Idaho.
No; not without A's consent.
What is meant by the " mother lode " in California ?
Give a description of it.
Deadwood, South Dakota.
The ordinarily accepted meaning of the term
"mother lode" as used in California conveys the
idea of a continuous fissure extending in a north-
westerly direction from Mariposa county, and filled
with metalliferous deposits. Another idea of it is
that it is not a single, unbroken, continuous fissure,
but a series of fissures of various lengths and widths,
within, and invariably conforming in strike with the
sedimentary rocks known as the black or Mariposa
slates. To give even a list of the articles written on
this subject would take up a page of this paper.
Probably the best among the more recent mono-
graphs on the subject is " The Mother Lode of Cali-
fornia," written for this paper by Ross E. Browne, a
two-page article in the issue of Jan. 29, 1898. The
finest thing of the kind is the Geologic Atlas of the
Mother Lode, just issued by the U. S. Geological
Survey. It is beyond praise for correctness and
completeness, would be cheap at $25 and can be had
by sending 50 cents (exactly that amount) to the Di-
rector of the U. S. Geological Survey, Washington,
D. C, with request for its receipt.
I know of a deposit of kaolin near here. What is it
worth and where could I sell it ?
Ashcroft, B. C.
If in considerable quantity, and favorably located,
a kaolin deposit might be made commercially valu-
able. It is found in several places from San Diego,
Cal., to the Alaskan line. When graded, washed and
ready for market, the best quality is worth about $14
per ton. It is largely used in the manufacture of
pottery and china. One of the principal markets for
it is at Trenton, N. J. Considerable is imported,
cheap, as ballast, and there seems little to say in
encouragement of our British Columbia corre-
spondent. _

Science vs. Technology.
A great deal of harm is done to technical progress
by scientific cant. According to scientific cant,
nothing that is technical is scientific. Science is only
concerned with phenomena, and not with their useful
application. If you experiment with 37 grammes of
steel in a porcelain crucible, or in a tiny electrical
furnace, with a standardized platinum pyrometer
and a spectroscope, you are doing scientific work ;
but if you work with a ton in a converter, this is
merely technical— though you will be patronizingly
told that your work may throw some light on scienti-
fic questions. No scientific man will deny in words
that the probable ultimate use to man is the cri-
terion of value of a scientific discovery ; but at the
same time the tacit assumption is that anything
technical is unscientific. The common type of scien-
tific man thinks his knowledge of necessity includes
all technical knowledge ; but he cannot for a moment
believe the technologist's knowledge may include his.
The result of this sort of scientific priggishness is
that technology is discouraged, and made out to be
less important than it is, while unimportant work is
exaggerated as to its value. Pure science, as it is
called, is considered something much higher than ap-
plied science. This is the wrong way round. The
terms are misapplied to begin with. One kind of
knowledge is not purer than another. What is called
pure science is really merely the raw material, and
the raw material has to be worked up by the en-
gineer for the use of man. Which is higher, the
raw material or the finished product ? In the case
of ordinary raw material, such as iron, it is pro-
duced intelligently, with the view of being worked
up ; that is to say, it is produced for a given pur-
pose. The scientific man does not work intelligently
in this sense. He produces raw material without
knowing or caring whether it can be worked up,
just as the insect produces silk. If anything, he
prefers what cannot be worked up. The sperm whale
sometimes produces ambergris, and al§o produces
other matter, but we do not admire the sperm whale
because he unintelligently produces what is some-
times valuable when worked up. This view of pure
science is so unconventional that few readers will
agree with it ; but it may be largely true all the
same. One idea is that it is beneath the dignity of
a scientific man to apply anything to technology." If
he finds out a new phenomenon he should read a
paper on it, but it is below his dignity to take out a
patent. One form of hypocrisy in connection with
this is the pretence that the scientific man works
entirely for love of science. He has no wish to
advertise himself or bring his name forward. If one
scientific man says, in the interests of pure science,
that he has done something which another man
claims, there is generally a very acrimonious dis-
pute— all in the interest of pure science, and not at
all in those of advertisement. The worst of it is
that the purely scientific man does not confine him-
self to his pure science, but considers that his knowl-
edge covers all applied science ex officio, and the
public unfortunately shares his view. — The En-
gineer.
A mine, the product of which is timber, is note-
worthy. A mine of this sort is to be seen in Tongkin,
China, where, in a formation of sand, at a depth of
from 14 to 20 feet, a deposit of the stems of trees,
which thousands of years ago must have existed as
an extensive forest, but eventually became buried by
an earthquake or other similar phenomenon, has
been opened and is now being mined through gang-
ways. The timber in no way forms any kind of coal,
but is in good condition, a fact to be attributed to
the large proportion of resin which it contains, and
to the sandy nature of the ground in which it lies.
The Chinese work the mine methodically, and use the
timber for sculptural purposes, coffins, troughs, etc.
The stems have a diameter of 3 feet, are 45 feet long,
and appear to be a kind of fir.
County Clerk Walker has received a letter from
J. R. Heaston, Indianapolis, Ind. , who says that in
1860 he located sixty mining claims in this county,
and wants to know whether his title is still good.
He says he has great faith in our mines. His faith
must be sublime to suppose his title good to lodes
located forty years ago and abandoned all that time.
We fear Mr. Heaston has been equally negligent in
his study of the Bible, or he would have been aware
that faith without works is dead. — Georgetown,

Suggestions on Inland Gold Dredging.
Written for the Mining and Scientific Press by A. C. Eteson.
To those who are interested in gold dredging a few
suggestions on the practical working of a dredger
may be of value. The following observations are
based on my own personal experience.
The dredger of which I am writing is of a con-
tinuous-bucket type, operated from the shore with
five steel lines — one head line, two bow side lines and
two stern side lines.
Each of these lines is wound on a separate drum in
the winch, which is operated by one man, so the
position of the dredger can be changed in a few sec-
onds.
No spuds being used, the dredger works on the
head line and so gains all the advantage of its resili-
ency. The gravel, after leaving the buckets, passes
through a revolving screen. The gold, sand and fine
gravel are washed out and pass over special tables,
where the gold is caught, the fine gravel and sand
passing over the stern. The coarser gravel, after
leaving the screen, is elevated and dumped behind
the dredger.
The dredger under consideration is an inland prop-
osition, operating some 4000 feet from the river.
An excavation 80x90x10 feet was first dug, into
which the hull of the dredger was placed. This ex-
the face, so as always to keep a full boat's length be-
tween the face and tailings. In ordinary digging
there are only two exceptions to this rule, viz : work-
ing a corner or opening out the face, to which I shall
refer later. One should not endeavor, under ordi-
nary circumstances, to work down to bedrock under
five or six cuts, or open out the face till bedrock is
reached. By the time bedrock is reached, there is
more tailing room, and now, if necessary, is the time
to open out.
The following is the method of working a corner:
(See Fig. 1.) When the dredger is within about half a

Ft&.l

U
'.vui'vwt))'"' '■■y-uyjwt
boat's breadth of the port side of the face, move the
stern over as far as possible to port, so that the tail-
ings dump on or close to the port bank. Now, as you
work with your ladder to port, pull the stern gradu-
ally over to starboard, until, when the ladder is on
the extreme end of the face, the tailings will have
filled up the gap behind. Now pull ahead and start
on a fresh cut, and, as your ladder works to star-
board, the stern gradually works to port, until when
the ladder is about half the breadth of a boat from the
you do not open out on the cut you are making, but
some few yards behind it.
Continue this operation on either end of your face
and you will find that, with care, you will always
have clear water from end to end of your face.
A veteran prospector's advice to locators of min-
ing claims is to follow the vein by sinking incline
shafts on the outcroppings in at least four places
along its course, after running open cuts at intervals
to determine whether the vein is continuous and holds
out in breadth and value a few feet below the surface.
After the vein has been prospected by the foregoing
mentioned methods in at least four different points,
assays of the rock will show whether the vein grows
richer in one direction or carries uniform values.
There is no other way by which the ground can be
shown up so thoroughly, and the ore taken out will
often go a long way toward paying expenses. Even
if the ore is not rich enough to pay for shipment, it is
always evidence of the value of the rock in the vein
and is a tangible, self-evident thing to show a pros-
pective investor. Again, shafts, vertical or incline,
that follow the vein, will show up any changes in the
ore and give a large amount in sight. Thus, four
shafts 50 feet wide down in a ledge 4 feet wide would
expose 1680 square feet on the vein. A tunnel driven
200 feet through rock to cut the vein would expose
but the section, the height and width of the tunnel,
say, 100 square. To expose a large area drifting
must be done, and such drifts can be run with better

cavation was then filled with water (Pig. 3) and the
machinery placed on board.
The boat was then ready for operation. The first
important point when the boat commences opera-
tions is the opening out of the face, or bank, to be
worked.
If commencing in rich ground, there is a tendency
to open out the face too rapidly, with the result that
you get in difficulty with your tailings. First, place
the dredger on one side of your face, as far back as
possible (Fig. 4), so as to allow the tailings to be
dumped on the bank behind. The tailings should be
so dumped that, on the completion of the cut, they
present one even line, and not a series of peaks
port side, the tailings will be dumped on the port
side of your tailings pile. Now pull the stern over
-~ — -£r~~
tttr.Z
i
Fig. 5. — Tailings as They Should be Stacked.
(Fig. 5), for by this means you economize tailings
space.
Too much care can not be taken in keeping the
sand and fine gravel from the sluices back. This can
be done with brush, sacks or lumber:
Continue working in the same position till you have
no more tailing room ; then move over a few feet to-
ward the open water, and repeat the operation till
you have worked across the face. Great care should
be taken always to keep the boat at right angles to
till the boat is at right angles to the face and you will
find that your tailings will be dumping on the star-
board side of the new line of tailings.
Work squarely across the face.
The starboard corner is worked in
a similar manner to the port.
To open out a face : (Fig 2.) This
is done in much the same way as
working a corner, the only difference
being that you have to work at a
greater angle to your face to enable
you to dig out the side. Suppose that
you are opening out to port : To get
your buckets in a position to do so,
you will have to pull your stern well
to starboard. Now you will find the
farther you pull your stern to star-
board the farther the tailings will
dump from the tailings pile ; this
might. fill up your floating space and
would get in your way when you
squared up and worked across your
face. To prevent this the following
method should be employed :
When you have pulled the stern
around sufficiently to enable you to
open out, if the tailings are dumping
over the tailings pile, let the boat
back as far as possible, so that the tailings dump on
the tailings pile. Then pull the bow into the bank
and open out according to your judgment and the
amount of tailing space. Then gradually pull ahead
and at the same time pull the stern in to port. Make
the tailings dump or the tailings pile when you are
once more square again. You will not have a square
corner to your face, but a.rounded one ; the greatest
width of your face will not be across the face you are
working but a little behind, so that in opening out
discrimination at the foot of a shaft that has followed
the ore. If indications of water are found in sinking,
and the prospecting of the vein, as described, demon-
strates that its value warrants the outlay in labor,
and the ground is situated so that the water can be
drained to a depth of 200 or 300 feet by tunneling,
then the latter is advisable, as it is obvious that drain-
ing a mine through a tunnel is far more economical
than performing that work with surface pumping
plants.
Very Quick Work.
On the line of the Chicago & Erie railroad, it had
been found advisable to replace bridge No. 30, an old
iron structure of 150 feet span, with a new steel
structure 151i feet long. The necessary changes in
the masonry made it necessary to trestle the track
and take down the old bridge. This was done and
the new bridge was erected at the side of the trestle.
When all was ready the trestle was taken down and
the new bridge was moved over into place. The fol-
lowing is a time record of the various stages of the
work :
Got use of track at 11:55.
Rails off bridge at 12:00.
Trestle down and all clear at 12:10.
Started to move the bridge in at 12:12.
Bridge moved over at 12:35.
Bridge lowered down upon the seats and a. 42-foot
approach girder raised to the surface of the new
bridge at 1:10.
Rails laid on bridge and spiked up ready for traffic
at 1:15.
The weight of the new bridge is 191,000 pounds.
No trains were delayed in making the change.
At the recent congress of German anthropologists
at Halle, Prof. Klaatsch of Heidelberg read a paper
contending that, as the result of several years' in-
vestigation, the alleged descent of man from apes
was no longer maintainable. His conclusion was
based on the construction of the bicephalous muscle
of the upper thigh. The professor incidentally con-
tended that it was a mistake to regard man as the
most perfectly developed mammal in all respects.
His limbs and teeth do not show any high degree of
development, and he is only superior to other ani-
mals by his extraordinary brain development.

Gleaner, on Taku arm, near Skaguay, ar-
rived in Victoria, B. C, on the 17th inst.;
it is estimated that it will return $12,000,
or 912 to the pound.
This year's yield of Nome and Klondiko
is expected to aggregate $2">, 7iio,iiiiii, di-
vided as follows: Klondike, $21,300,000!

smelter.
"Thoso who bellevo that the sea washes
up the gold on tho beach at Nome are la-
boring under a wrong impression. Tho
sea concentrates the gold which is carried
down to the tundra and beach by the
mountain streams. As for the bedrock,
wbioh has deluded so many persons, that
is a false bottom, the true bedrock being
in some places 30 feet below the false bot-
tom," M. J. David says, who has been
working in the Nome district.
Teller City, the new town on Port Clar-
onco bay, though only about six months
old, seems destined to rival Nome within

that 1200 people are wintering there.

The plans for the construction of re-
straining barriers along the Sierra foot-
hills, for which the State and Federal
Governments have made large appropria-
tions, may now be carried out under the
terms of a decision this week by Attorney-
General Ford. Under the California De-
bris Commission Act of 1897 an appro-
priation of $250,000 was made, and Congress
599
Mining and Scientific Press
December 22, 1900.
set aside a like sum for the purpose, mak-
ing a total of $500,000 in all. The plans of
the Federal engineers engaged called for
an expenditure of $800,000, and the State
Board of Examiners, being restricted in
its jurisdiction to plans involving an out-
lay of no more than $500,000, feared to
lend its approval to the plans. The attor-
ney-general calls attention to the fact
that a subsequent Act of Congress pro-
vides that the Federal engineers may pro-
ceed with the work to the extent of
$500,000, leaving the remainder in abey-
ance, awaiting further action of Congress
or the State Legislature, and declares
that the plans and specifications for this
expenditure of $500,000, afterwards sub-
mitted, may properly receive the appro-
val of the State Board.

LAKE COUNTY.
After the expenditure of nearly $200,-
000 on the Adams, Maid and Wolftone
lease, for hoisting, pumping and milling
equipment and putting the underground
workings in good condition, this group,
which is under a 10-years lease to the A.
M. & W. Leasing Co., is now ready to be-
gin operations on a considerable scale,
both in production and development. The
group comprises three distinct properties,
with a deep shaft on each, and after Feb.
1st next the Mab mine, which adjoins on
the north, will become a part of tine main
group, all under the management of S. D.
Nicholson. The underground workings
are all connected and the Wolftone shaft
will be the center of operations. The
hoist, boilers and gallows frame here have
been previously described. A dynamo has
been put in to supply light to the mines
and the top premises. The water is
handled by two Knowles duplex, triple-
expansion pumps — one at the 700 and the
other at the 1000-foot station. At present
1000 gallons are being handled. At each
pump station the water is bulkheaded and
connected with the pumps by a 12-inch
suction pipe. At this shaft the sulphide
ledge was struck at depth of 700 feet.
The present depth is 1100 feet and sinking
continues, with the idea of entering a
contact at greater depth. A sinking
pump follows the work down, handling
the increasing flow of water.
Within the last few months the A. M.
& W. management has equipped a con-
centrating mill on the premises, which at
present is handling eighty tons of ore
per day. This ore, while it comes from
the Wolftone proper, comes through
the old Adams shaft. Three mills crush
the ore to a uniform mesh, the material
being separated by hydraulic sizers, the
coarser and heavier passing direct to six
Wilfleys, the slimes passing to six cone-
shaped settlers provided with overflow
gates ; the settlings run through to other
concentrators there being one table under
each settler. The overflow from the
settlers passes to a series of settling boxes,
where a final slime product is obtained.
A vibrating conveyor delivers the con-
centrates from the tables to the shipping
bins. By this method of separation two
products are obtained, viz.: a lead-iron
with small per cent of zinc and a purely
zinc product, which runs about 45% of that
metal. A Bartlet table is being added to
make further concentration tests.

OURAY COUNTY.
At the Virginius mine and Revenue
tunnel of the Caroline M. Co. the shaft,
which starts near the breast of the 7500-
foot tunnel, has reached a depth of 650
feet, and the intention is to sink to 1000
feet depth, which it is expected will take
it into the quartzite. This shaft starts
on the hanging wall side of the Virginius
vein, cuts through the latter at 550 feet
depth, and the work is now in foot wall.
Stations have been cut 200 feet apart and
it is the intention later to crosscut from
each station to the vein. Present depth
of this shaft gives a vertical depth on the

Notices of Recent Patents.
Among the patents recently obtained
through Dowey, Strong & Co. 's Scien-
tific Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Revolving Cylinder Engines.— No.
663,087. Dec. 4, 1900. James D. McFar-
land, Jr., San Francisco, Cal., one-half
assigned to John Bruckman, same place.
This invention relates to an engine in
which cylinders are mounted radially with
relation to an axis about which they are
revoluble, and the piston rods on said
cylinders are connected with a second
shaft which is eccentrically placed with
relation to the first named shaft, whereby
a reciprocation of the pistons in the
cylinders is produced by their revolution
around the two centers. It consists of a
series of radially disposed cylinders having
closed ends, a wheel, a central shaft with
relation to which it is turnable, and with
the rim of which wheel the cylinders are
connected. A second shaft is eccentrically
located with relation to the first shaft and
has inlet and outlet passages for the pro-
pelling medium. Hollow piston rods ex-
tend through stuffing-boxes in the inner
heads of the cylinders and have independ-
ent passage therethrough communicating
respectively with the cylinder chambers
upon opposite sides of the piston. Rings
inclose the supply shaft and with these
rings the hollow piston rods connect. A
sleeve is interposed between the rings and
the shaft and has slots which coincide
periodically with the passages in the
shaft and thus lead to the hollow pis-
ton rods whereby the propelling medium
is alternately admitted and exhausted
from opposite sides of the piston.
Bed Bottoms.— No. 663,171. Dec. 4,
1900. John Hoey, San Francisco, Cal.
The object of this invention is to overcome
the difficulties hitherto experienced in
the bed bottoms constructed of an elastic
woven netting stretched upon a frame-
work, and this is done by dividing the
strain between the end rails and the side
rails. This is effected by using a series of
cables extending from one side rail to the
other and having endwise elasticity, with
means by which the tension of these cables
can be increased by drawing the central
portions of two contiguous cables towards
each other transversely of their length.
The bed bottom consists of a rigid rec-
tangular frame, a fabric connected with
the end bars of the frame, and uncon-
nected with the side bars thereof, means
for reducing the strain of the fabric upon
the end rails and dividing said strain be-
tween the end rails and side rails, consist-
ing of elastic cables extending transversely
across from one side rail to the other be-
neath and in contact with the central por-
tion of the fabric whereby the tension of
said cables acts upon the frame at right
angles to the tension of the fabric. Means
are provided for connecting the transverse
cables in pairs so that the cables of each
pair may be drawn toward each other and
their tension increased, with means for
connecting one pair of cables with the
other.
Pipe Wrenches.— No. 663,567. Dec.
11, 1900. P. Frichette, Sheridan, Cal.
This invention is an improvement in pipe
wrenches, and consists of a single integral
December 22, 1900.
Mining and Scientific Press.
602
bar folded about midway upon itself to
form converging jaws, and split from a
point near the outer end of tbe folded por-
tion to form two straight and parallel
Bides separated from each other. These ,
sides are provided with adjusting holes
and a lover having a corrugated and
beveled end, is fulcrumed in eithor of the
holes so as to compress the pipe between
itself and the two separated sides and the
folded portion which forms the final point
of contact. Thus clamped, a sufficient
purchase may be brought upon the lever
to oasily turn the pipe in oithor direction.
BuEQLAB Alarm Door Lock.— No.
«l)3,586. Dec. 11, 1900. Jennie Simoni,
San Francisco, Cal., one-half assigned to
W. K. & I. C. Hays of same place. The
object of this invention is to provide an
independent movable device which can bo
placed in contact with a closed door with-
in tho room and mechanism carried by the
device which will be operated by any pres-
sure applied tending to open the door. It
consists of a spring-actuated alarm with a
locking device, a base plate upon which
this is carried with fixed points adapted
to rest upon the floor, a slidable rod hav
ing a point adapted to rest against the
surface of tho door and an angular ring I
having its opposite sides pivoted to the :
base plate, said ring carrying a detent j
upon one edgo which engages and normally
retains the alarm out of action. An in-
cline upon the opposite side is in line with
the slidable shank of the movable point,
so that any movement of these parts dis-
engages the detent and sounds the alarm.
Transmitting and Reversing i
Gear.— No. 663,603. Dec. 11, 1900. J. E.
Doak, San Francisco, Cal., one-half as-
signed to Wm. Leviston, same place. The
object of this invention ie to provide a
simple transmitting and reversing gear
for engines. It consists of a driving shaft,
a driver fixed thereto, a sleeve having its
major axis in the direction of the length
of the shaft, and loosely mounted thereon,
a second driver on the sleeve, a trans-
mitter adapted to occupy the space be-
tween the two drivers and mounted in tho
plane of the axis of one of them; a moans
for disongaging or engaging the trans-
mitter with the two drivers, a clutch
member fixed to tbe driving shaft, a
second clutch membor rigid with the op-
posite end portion of the sleeve and a
unitary mechanism whereby tho clutch is
engaged or disengaged simultaneously
with the disengagement or engagement of
the transmitter with tho drivers.

Probably the most noticeable result of the elec-
trical exhibit at the Paris exhibition will be the
standardization of the systems of generating electric-
ity, on the lines suggested editorially in this and
other technical journals, and the more universal use of
the three-phase alternating current at from 2000 to
6000 volts.
The building of the Los Angeles & Salt Lake
Railroad will be a big factor in the mineral develop-
ment of the section traversed by the new line. It
is a region of great mineral wealth, but its inac-
cessibility has always worked against its develop-
ment. Already Los Angeles complains of a scarcity
of mining men and prospectors, many of the latter
having started to locate claims along the supposed
route.
There were about thirty great inventions and dis-
coveries during the century now closing that deserve
especial mention as being in the front rank of scien-
tific progress ; railroads, steamships, the telegraph,
the telephone, lucifer matches, gas illumination,
electric lighting, photography, anaesthetics, anti-
septic surgery, conservation of force, germ theory
of disease, organic evolution, the antiquity of man,
the glacial epoch, the Roentgen rays, the spectro-
scope, the Bessemer process, the periodic law in
chemistry, cell theory and embryology, the modern
printing press, vortex theory of matter, the nebular
theory, the uses of dust, the molecular theory of
gases, the cyanide process, the cotton gin, the sew-
ing machine, petroleum, electric power, modern min-
ing methods.
During the year the U. S. Government has had a
new plan in operation for the first time, whereby a
saving of about $65,000 was made in the manner of
refining at the several IT. S. mints. It is necessary
to mix a certain percentage of silver with gold in
refining it, usually about two parts of silver to one of
gold, as with the excess of silver the acid acts freely,
dissolving all the silver. Prom the beginning till
1900, the U. S. mints used their own silver over and
over again in this process, gaining nothing either in
profit nor in quality of the work. This year the
Government mints were authorized by law to do re-
fining for individual customers as well as for its own
coinage, provided that the charges do not exceed the
actual cost of the work. The Treasury Department
lowered the scale of charges for refining silver, for
the first time since 1880, so as to attract silver held
by private parties, and thus get what it needed for
its gold refining with compensation therefor.
The End and Beginning.
This is the last issue of this paper in the nineteenth
century. Next Saturday's issue — No. 2111 — will be
the first one of the twentieth century. The essence
and spirit of the century closing has been the rise of
science ; this great adjustment of industrial condi-
tions will tend to still further widen individual oppor-
tunity in the coming century. It is the end and
beginning — the end of a century of great progress,
the beginning of an era of greater development. The
century has been a great one for the United States,
expanding from 5,000,000 feeble residents on a strip
of Atlantic coast to 77,000,000, dominating a conti-
nent, foremost in all victories of peace or war,
potent in discovery and master of the world's forces.
In the beginning of this century the past seemed
narrow, the future grew broader, the horizon
widened ; now, on the threshold of the twentieth cen-
tury, the achievements of the past hundred years,
great though they have been, seem but the indica-
tions of what awaits humanity.
The inventive mind, the scientific research, the
enterprise of the daring, the chance for individual
advancement, the perfection of modern machinery,
the precision and economical result of modern min-
ing methods, are among the forces and attributes
that have made this century able to make its suc-
cessor heir to so rich a legacy of organized indus-
try, advanced knowledge and perfection of method
and mechanism.
At the base of all this lies mining and scientific
progress ; the scientific miner is the man who, beyond
all others, has made the nineteenth century the great-
est of all those periods of time since time first began
to be so measured. In this country, especially, min-
ing— the basic industry of the nation — has created
commonwealths, populated vast regions, developed
their resources and contributed its quota to making
the United States the commanding power of the
planet. Upon the basis of scientific mining is reared
the nation's industrial and commercial prosperity.
Bullion is the blood of business, and the product of
the pick and drill circulating in the nation's financial
veins has vivified every fiber of material life. The
miner is the great creator of eternal wealth. Unlike
other forms of evanescent riches, the miner's product
takes on the attributes of immortality and lives for-
ever through the centuries, shedding a luster on the
passing years and sustaining innumerable succession
of enterprises in Time's course. The miner and pros-
pector are the avant couriers and sustainers of civil-
ization ; they carry the gospel of development across
mountain and desert, and beyond the frozen northern
seas they hold aloft, full high advanced, the flag of
progress, and with unequaled sublimity of self-reliance
they lead wherever hope sweeps on with flashing fin-
ger pointing to the golden goal.
Let circumstance oppose them,
They bend it to their will ;
And though the flood o'erflows them,
They dive and stem it still.
Let lower spirits linger
For hint or heck or nod,
They only see the finger
Of an onward urging God.
All hail and honor to the prospector, the miner,
the scientific searcher, the metallurgist, the man in
any and every capacity who makes and maintains
the pre-eminence of the mining and scientific devel-
opment of the century, and for him may the star of
victory ever glitter in the strife !

Notable Electrical Transmission.
California has several notable electric transmission
plants whose magnitude has attracted universal at-
tention. In the State of Washington, in the north-
western corner of the Union, is an electric transmis-
sion system deserving of notice. A brief account of
the successful transmission of electrical energy
thereby, a distance of 153 miles on Nov. 13, 1900, is
given in this week's issue. Several previous refer-
ences have been made to the "work as it pro-
gressed.
The plant is at Snoqualmie Palls, Wash., where the
Snoqualmie river has a vertical drop of 270 feet, giv-
ing an available energy of 35,000 H. P. All the
electrical machinery, together with the water
wheels, is installed in a large chamber directly under
the tail race tunnel that extends to the river below
the falls. Impulse wheels on horizontal shafts and
aluminum wires for transmission are among other
notable features, beside a submerged concrete dam
built across the river, which raises the low water
elevation of the river 6 feet at the intake.
There are four electrical generators, each of 1500
K. W. capacity, each weighing about 100,000 pounds.
They are of the revolving armature type, delivering
a three-phase current at 1000 volts, 7200 alterna-
tions, the normal fuel load current being 1000
amperes per phase. The armatures are 96 inches
diameter, speed 300 revolutions per minute, the
peripheral velocity being thus almost 1J miles per
minute. Without load the generators require a field
current of ninety-five amperes at ninety volts ; with
full non-inductive load, 100 amperes to maintain the
same electro-motive force. It is calculated that in
these armatures about 4,500,000 foot-pounds of en-
ergy is stored at 300 revolutions per minute, the
stored energy in a single revolving armature equal-
ing the electrical output of that armature at full
load in four seconds.
In the transformer house at the head of the shaft
the current is received at an initial voltage of 1000,
and, passing into the step-up transformers, is raised
to 30,000, the nominal -voltage of transmission.
Cables of twisted aluminum wire carry the 1000-volt
current from the switchboard to the transformer
house; the conductors running first to the step-up
transformers, and thence to a second switchboard
controlling the transmission lines. A high-tension
plug-board in the transformer house permits any
desired combination of transformers and circuits.
Similar plug-boards are arranged at Renton, Seattle
and Tacoma, and it was by the use of those plug-
boards that the combination was made last Novem-
ber, as described elsewhere in this week's issue,
that made possible the circuit from the power house
at the falls to Seattle, back to the falls, thence to
Tacoma, and again back to the falls — an entire dis-
tance of 153 miles.
The circuits are all of stranded aluminum cables,
this being, so far as known, the first instance of the
use of this metal in such long-distance transmission,
though aluminum cables are in use in two California
long-distance electrical transmission systems. The
electrical conductivity of aluminum is about 60% that
of copper, so that an aluminum cable so employed to
have capacity equal to copper needs to have a cross-
section 661% greater, though with such increased
size the weight is but one-half that of copper. In
California some difficulty is found in splicing, and the
greater surface exposed to storm entails disad-
vantages not entirely overcome.
The Snoqualmie Palls Power Co., operating the
system here briefly described, has stations at several
points on its line and at the termini, and is develop-
ing 10,000 H. P., supplying light and power, with
ability, if desired, to produce and furnish all require-
ments in that direction far beyond its present
capacity.
A generation ago deep mining west of the Rocky
mountains culminated on the eastern slopes of the
Sierras in shafts from 2700 to 3300 feet deep on the
Comstock, Nevada. In the Calumet copper mines
of Michigan are now the deepest mine shafts, where,
within an area of one square mile, the Tamarack
M. Co. has three shafts, 4450, 4650 and 4750 feet in
depth, respectively, and the Calumet & Hecla one of
4900 feet vertical depth. The former company pro-
poses this year to sink one of its shafts — No. 5 — to a
depth of one mile from the surface.

IN mine surveying the difficulty sometimes found in
sighting the fine string hanging from the station roof,
carrying a plumb-bob, can be obviated in the case of

The permanganate process of gold recovery has been
repeatedly described herein, and while experimental
tests have reported satisfactory results, so far as known
the process has not in an extended or commercial way
yet given evidence of commanding value.
If an ounce of iron and a ton of iron were dropped
from the same vertical height at the same time, the
ounce piece would reach the ground first, because of the
resistancy of the air. In a vacuum all bodies, regardless
of weight, fall with the same velocity through any dis-
tance.
The atmosphere extends at the equator 26,000 miles
beyond the earth, and at the poles 17,000 miles. The old
estimates of the height of the atmosphere based on de-
crease of temperature of 1° C. for each 100 meters eleva-
tion are abandoned. The actual decrease is 0.6° per 100
meters.
Under a contract for milling ores which provides that
"said ores, rock and earth shall he worked in tho usual
and ordinary manner of working like ores, and returns
therefrom shall not be less than 70% of the pulp assay,"
the return is for an average of 70% and not on each ton
of ore furnished.
In the C. Grollet chlorine and bromine process for the
extraction of gold, chlorine is introduced at the begin-
ning of the operation and bromine at the end, the opera-
tion lasting usually eight to twelve hours. The process
is claimed to give satisfactory results at an experimental
plant at Harfleur, France.
The energy transformed by one gallon of liquid air,
when evaporated and expanded into 800 gallons of air of
ordinary temperature and atmospheric pressure amounts
to approximately J H. P. for one hour. A moderate
estimate of the cost of liquid air, when produced in quan-
tities, is 20 cents per gallon.
At sea level, to raise water which flows freely to the
suction pipe of a pump to a height of 8 feet requires at
least 7 inches of vacuum ; this corresponds to an atmos-
pheric pressure of 11.228 pounds; at- that pressure water
boils at 198° F. The pump would not, probably, lift
water at a temperature exceeding 150° F.
A "bedded vein" is understood to mean an ore
body or vein matter lying about as a seam or bed of
coal lies between sandstone strata, horizontal or in-
clined, as are the strata between which it exists. A fis-
sure vein may cut clear across the stratification planes of
the rocks ; a bedded vein does not, but conforms to then-
dip or lay.
A $20 gold piece weighs 516 grains— 1.075 ounces.
Of this, 90% is pure gold and 10% copper, there being
.9675 of an ounce of pure gold and .1075 of an ounce of
copper. One ounce of pure gold is worth $20.671834625;
the actual amount of pure gold in a $20 gold piece is
$19.9981999368, so that if there be no loss by wear or
abrasion there is practically $20 worth of pure gold in a
$20 gold piece.
THE total exports of sulphur from all Sicily during
1899 amounted to 490,325 tons, of which '134,288 tons
came to the United States; the average price was $18.72
per ton, against $18.85 during the year before. As to
the quantities exported to the United States during the
last seventeen years, the highest figure touched was in
189], when it reached 821.95 per ton; the lowest, in 1895,
averaged $10.86 per ton. The largest quantity shipped
during any one year was in 1898 — 142,553 tons; smallest
quantity, 1887, 68,347 tons.
With a triplex pump forcing water to the surface, the
delivery pipe discharging at an elevation of 300 feet
above the pump, the pressure gauge connected with the
bottom end of the delivery pipe indicating a pressure of
144 pounds per square inch, the velocity of the flow
through tho 6-inch delivery pipe is 688* feet per minute,
and tho quantity pumped per minuto is 135.2 cubic
feet.
Mineral lodes are ordinarily more recent than the
rocks they traverse, and older than the rocks or lodes
by which they are intersected. Nor are mineral veins
all of the same age; they are of different ages and differ-
ent places, the same as the mountain ranges and the
dykes of igneous rocks are of different ages. Each vein
system owes its existence to local events and conditions,
both at the surface and at depth.
Much of the most desirable and valuable matter pub-
lished herein each week is furnished by the readers of
this paper, referring to work that they are doing or in
which they are interested. Probably no other journal
published contains so much original material from the
men who do what they write about. Such matter is
always gladly received, and any expense attached to
securing available material will be cheerfully audited.
The tractive power of a mine locomotive is found as
follows: The diameter of the cylinder squared, multi-
plied by the length of stroke in inches, multiplied by the
mean effective pressure in pounds, divided by the diame-
ter of the driving wheel in inches, equals the total tract-
ive power. The mean effective pressure in the cylinder
is assumed at 85% of the boiler pressure The tractive
power of a locomotive multiplied by the speed in miles
per hour, divided by 375, gives the horse power developed.
If charges of gas pass through the engine unignited
when the engine is working under a fair load it is ordi-
narily an indication of need of repair of the igniter. With
an electric igniter employing a battery as a source of
current, it is frequently the battery that is at fault.
Open circuit batteries when nearly exhausted regain
some strength when rested over night, and will furnish
ample current for a short time, but rapidly weaken in
use. If the battery has run for some time it should be
renewed, and the effect upon the ignition noted.
At Anaconda, Montana, the slimes average 50% sil-
ver, 0.5% gold, 15% copper, and 34.5% valueless impuri-
ties. They are washed and put into a lead-lined tank,
with three parts 66° sulphuric acid and one part water.
Steam and air are introduced through a perforated lead
pipe by means of an injector. This treatment oxidizes
and dissolves the copper, together with some of the im-
purities. The slimes are then washed on a filter, dried,
mixed with one-fifth their weight of soda ash, and
melted in a small reverberatory furnace, finally being
cast into bars of bullion 980 fine. This bullion is shipped
to the parting works for separation of the gold and
silver.
A, having located a tunnel site, subsequent mining
locations on the line thereof are prohibited so long as
work is being prosecuted with reasonable diligence in the
tunnel; if B locates a mining claim subsequent to A's tun-
nel location, the latter is senior in point of time, and A
may drive his tunnel through B's claim without his con-
sent. If, however, A and B are simply locators of min-
ing claims which may be near or join each other, A has
no right to pass through B's claim, although B may be
junior in point of time to A. The location of a mining
claim does not carry with it the right to pass through
other claims subsequently located. The consent of the
junior locator is essential.
The style spoken of is the hydraulic chief knuckle
joint and nozzle with two elbows placed in reverse posi-
tion, when in right line, connected by a ring in which
are anti-friction rollers. The ring is bolted to the flange
on the elbow, but gives the upper elbow free horizontal
movement, while vertical movement is obtained through
a knuckle joint placed in outlet on the top elbow. This
joint is a concave surface fitted to a convex one, the
former having an opening for the pipe to pass through.
The interior is unobstructed by bolts or fastenings, and
the man at the pipe operates it by a lever. Vanes or
riffles are inserted in the discharge pipe, to prevent a
rotary movement of water caused by the elbows, and to
force it to issue in a straight, concentrated and solid
form.
If the co-owner or owners in a mining claim neglect or
refuse to put up or do their share of the annual work
necessary to hold the claim, he or they interested who
want to hold it should first do the required assessment
work, then give the delinquent legal notice by personal
notice in writing or by publication. If in the former way
after ninety days the delinquent fails to pay his share
his interest becomes the property of him or them who
have done the required work ; if by the latter way, the
delinquent has ninety days after the last date of publica-
tion. "Advertising out " a delinquent co-owner is never
a pleasant job, and everything done should be in strict
accord with all legal requirements, including filing of cer-
tificate of annual expenditure with the county recorder.
In case of subsequent demonstration of value there is
often likelihood of contested title, and in such case the
holder of the claim should be fortified by legal proof of
his rights. •

Director Roberts, of the United States mint,
says that 1901 will show the greatest gold production
the world has ever known. "We estimate from data
in our possession, " he says, " that the world's pro-
duction next year will reach a total of $365,000,000.
The year 1901 will show that the United States is
again at the head of all countries as a producer of
gold. Our total next year will probably rise to $94,-
000,000, eclipsing Australia and South Africa for the
first time in several years."
The close of the century has about perfected the
steam engine, which is still the great motor; it has
bought the gas engine, the air compressor, the elec-
tric motor and the water wheel to a degree of per-
fection that seems to make difficult further progress
in efficiency. All these are of foremost use in mining
and metallurgy. The close of the century has de-
veloped steel production and the smelting of ore from
carefully guarded and costly secret processes to a
cheap simplicity that makes practical their universal

New Methods for the Extraction
Copper and Zinc.
of
Written for the Mining and Scientific Pkess by Dr. J. Ohly.
The month of October of the present year has been
remarkable on account of the discovery of new and
advantageous processes employed for the purpose of
extracting copper and zinc from their respective
ores. These processes have been covered by patents,
granted by the United States Government, and are
worthy of intimate study, since they disclose a new
principle of chemical nature, which was not known
unto the present. The first of these patents com-
prises the employment of "nitre cake," a material
resulting in the manufacture of nitric acid from
sodium nitrate (Chile saltpetre) and sulphuric acid.
The main point of this manufacture consists in the
expulsion of all the nitric acid contained in the salt-
petre at a low temperature, so as to prevent any
loss occasioned by the decomposition of the acid
fumes produced. When this point has been reached,
the remaining product, known as nitre cake, consists
on the average of 75.8% of sodium sulphate, 16.68%
of sulphuric acid, 6% water, and 1.52% of insoluble
residue. An aqueous solution of this nitre cake has
the capacity of dissolving copper and zinc from the
respective ores, with the proviso, however, that the
latter, if consisting of sulphides, must be subjected
to roasting beforehand, while oxides and carbonates
can be leached successfully according to this process
without resorting to any other preliminary prepara-
tion of the ore than crushing and grinding. It has
been found also that a 5% Baume solution answers
best for the extraction of the ore, since the solvent
shows under these conditions a selective propensity
for the copper and zinc present, and touches but to
a limited extent the iron or aluminum compounds
eventually contained in the material to be treated.
The solutions resulting in this manner are freed of
their metallic contents either by the electrolytic or
chemical method, when, in both cases, the copper is
precipitated first in the metallic state, and the zinc
remains in solution to be recovered afterwards.
The chemical reaction underlying tins process con-
sists evidently in the formation of a readily soluble
double salt of copper, zinc and sodium sulphates, and
is induced by the presence of free sulphuric acid. As
the solving action of sodium sulphate, in the form of
nitre cake when in aqueous solution, was not known
unto the present, this point constitutes the intrinsic
value of the patent.
The inventor of the process, C. 6. Collins of New
York, added, however, two further modifications to
the original method, and for each of the three, the
United States Government has granted separate
patent rights on October 9 of the present year. In
the second process, No. 659,339, salt cake is em-
ployed instead of nitre cake — the former a product
resulting during the first step of soda manufacture
from salt and sulphuric acid according to the process
of Leblanc. The by-products in the latter consist of
hydrochloric acid — besides others not considered
here — which serves, when added to black oxide of
manganese, for the production of chlorine, by means
of which bleaching powder or chloride of lime is
manufactured subsequently. These two by-products
— hydrochloric acid and bleaching lime — have con-
tributed greatly to keep alive the old Leblanc
process, whose invention dates back into the turbu-
lent times of the French revolution, and represents
one of the saddest incidents connected with the cre-
ation of an ingenious and inventive mind.
In 1775 the French Academy of Sciences offered a
high price for the discovery of a process answering
the artificial preparation of soda. Nicolas Leblanc
was the man to accomplish the project, and, having
submitted his process to the Duke of Orleans, he suc-
ceeded in obtaining the necessary capital from that
personage in order to carry out his proposition on a
commercial scale. The merits of his invention hav-
ing been acknowledged, a patent was granted to him
by the French Government, which comprised practi-
cally all the steps of the process as it is applied at
the present day. Soon after other manufacturing
operations of this character were commenced, and
the brightest prospects opened for the inventor and
his associates, when the duke was thrown into prison
by the revolutionists under the accusation of assist-
ing in the manufacture of a product "hurtful to the
public health," found guilty forthwith and beheaded
in the year 1793. This ruthless procedure of the
" Committee of Public Welfare " was followed by an-
other harsh and malicious step, compelling Leblanc
to renounce the stipulations of his patent " for the
benefit of the country." In spite of his protestations
only the paltry sum of 600 francs was awarded to
him as indemnification of his losses, and he was left
to console himself as best he could for the following
years, when in 1801 the soda works were returned to
him by decree of Government. But, being without
capital at this period, he found it impossible to start
the works or even to compete with others, which had
had been established in the meantime and were profit-
ing by his invention. Ultimately a committee ap-
pointed to investigate his claims awarded him a small
remuneration, the insignificance of which drove the
inventor to despair, so that he, crushed by the in-
gratitude of his countrymen, made an attempt on his
life, and died a miserable death. Though he left his
family in the most destitute circumstances, the small
sum granted by the committee was never paid to his
wife or children surviving him.
This dreadful experience of the inventor of a pro-
cess that has brought untold millions into the coffers
of the soda manufacturers of the civilized world is
proof for the saying that "the way of the inventor
is hard," or for the more vulgar variation, " the in-
ventor don't get anything," reminding one of the sad
lines of Robert Burns in " Despondency," which read :
O life ! thou art a galling load,
Along a rough, a weary road,
For wretches such as I —
In the course of years quite a number of processes
aiming at the manufacture of soda, among them the
cryolite, ammonia, and several electrolytic methods,
have entered into competition with the old invention,
so that it has been limited in cases to the manufacture
of salt cake, bleach, and hydrochloric acid exclu-
sively. The compound resulting on roasting common
salt or sodium chloride with sulphuric acid is naturally
an inexpensive product, which can be manufactured
or bought in quantities to suit, and consists approxi-
mately of 95% sodium sulphate, 2% sodium chloride,
2% of sulphuric acid, and 1% magnesium sulphate,
the latter being a usual admixture, in the form of
chloride, to common salt, and imparting to it hygro-
scopic properties.
It will be readily seen, that the roasting of salt
with sulphuric acid for the production of salt cake
may be carried on to advantage in localities where
the two ingredients required can be bought at the
lowest figures. Conditions in this respect are un-
doubtedly favorable in any of the Western States,
and it seems, therefore, that this manufacture might
be profitably employed in combination with the leach-
ing of copper-zinc ores and the subsequent production
of the two metals. Since the price of copper has
been in the ascendancy for the past six months, and
has reached the respectable figure of 17 cents per
pound at present, whlie that of zinc may be put down
as 5 cents for the same amount, there is every reason
extant to declare the erection of such works a very
lucrative undertaking. This favorable condition is
even maintained at present for copper alone, when
the recovery of this metal from low-grade ores is
carried on by means of sulphuric acid, which must be
considered as an expensive article in comparison to
the extremely low-priced solvent resulting in the
manufacture of salt cake and the by-products con-
sisting of hydrochloric acid and bleaching powder.
As these articles bring good figures in the market, it
would seem that the point under consideration repre-
sents an inducement of extraordinary merits.
There remains, however, one phase in the manu-
facture of salt cake, which deserves special consider-
ation, and that is the utilization of the hydrochloric
acid, resulting as one of the by-products. It might,
of course, be conducted into water, which absorbs
the acid fumes with avidity, and thus form the com-
mercial article, known as muriatic or hydrochloric
acid. The latter may serve subsequently for the
manufacture of bleaching powder, but a more profit-
able and direct utilization of the same would consist
in employing it also for the extraction of copper and
zinc from the ores by introducing the gas into the
water of the tanks containing the crushed material,
when it will gradually dissolve in the former and
attack the copper and zinc present so as to form a
solution of the two chlorides of these metals. The
final result would, therefore, differ from that accom-
plished on applying salt or nitre cake merely by the
nature of the copper and zinc salts produced, which
would be chlorides when using hydrochloric acid, and
sulphates in the other case. The subsequent separa-
tion of copper and zinc from these solutions would
offer no special difficulties.
Experiments made in this regard by the author
show clearly, that the point taken is a correct one,
and that the extraction of copper-zinc ores, effected
by the simultaneous employment of salt cake and
hydrochloric acid gives very encouraging returns.
Ores of the character desired not being readily ob-
tainable, equal weights of wasted ehalcopyrite, cop-
per glance and unroasted copper carbonate were
mixed with the same amounts of roasted zincblende,
and the resulting mixture ground to pass through a
fifty mesh sieve. One gramme of each sample, thus
obtained, was then brought in solution, and the cop-
per and zinc contents determined by the usual titra-
tion processes. After that, ten grammes each of the
three mixtures were covered with a measured
amount of water, when the fumes of hydrochloric
acid, produced by heating a weighed amount of salt
and sulphuric acid in a glass retort, were conducted
into the water to saturation, and left in contact with
the ore for twenty-four hours. Three other samples
of the same weight and kind were then covered
with a 5% Baume solution of the salt cake pro-
duced, and the mixture allowed to stand for the
same amount of time. The six solutions thus ob-
tained were then drawn off, and their relative cop-
per and zinc percentage determined as before, when
the analytical results showed that the extraction
percentages for the mixture of unroasted carbonate
and roasted zincblende, when treated with salt cake
solution amounted to 97.8 in copper and 88.9 in zinc,
for the mixture of roasted copper glance and blende
to 99.4 and 87.6 respectively, and for that of roasted
ehalcopyrite and zincblende to 92.4 and 85.5. The
extraction of copper, effected by hydrochloric acid,
on the other hand, approached closely the figures
obtained by the treatment with salt cake solution,
while the percentages of zinc were considerably low-
ered, and amounted to 87.3 in the first case, 75.5 in
the second, and 72.4 in the third case.
The separation of the metallic copper and zinc
from equal volumes of the six solutions, pre-
pared and tested in the same manner as before, was
accomplished by the electrolytical method only, and
the results obtained were compared with those re-
sulting through analysis. They were found to ap-
proach these figures closely.
The third patent, granted to Mr. Collins under the
same date, and numbered 659,340, comprises the em-
ployment of both salt cake and niter cake, presum-
ably in equal parts by weight, for the preparation of
the solvent. In this case, as in the others, the obser-
vations made as to the strength of the solution for
the first and second patents hold good, and it is ad-
vised to use a strength of 5% Baume in case the ore
carries large quantities of iron, aluminum or other
soluble substances.
On closer observation of these patents the thought
might occur to the reader that they can be readily
circumvented by using sodium sulphate or glauber
salt, sulphuric acid, and water, in the proportions of
75.8, 16.68 and 6, respectively, in the first case, and
sodium sulphate, salt, sulphuric acid, and magnesium
sulphate in the relative proportions of 95, 2, 2, and 1
in the second case, though the price of the solvent
obtained in this manner would be raised thereby to
some extent. By mixing these ingredients in the
proportions of 85.5 for glauber salt, 9.34 for sul-
phuric acid, 1 for salt, 0.5 for magnesium sulphate,
and 3 for water, the third solvent would result, and
the owner of the patents would not have the right to
interfere with the application of these three solvents,
prepared in the manner indicated. Though it would
be unjust to encourage or induce such practices, the
writer cannot refrain from pointing out the risk in-
curred by inventors through the obligation, imposed
upon them by the Government, to explain every de-
tail of their processes in the patent applications,
after which the information given is usually spread
broadcast by journals and daily papers of the
country.
A lixiviating works for the extraction of copper
ores, erected on the principles explained above,
would preferably be located on a hillside of gentle
declivity, the upper terrace being of sufficient size
to allow of the erection of a furnace for the manufac-
ture of salt cake, and, in immediate proximity to it,
of the placing of two tanks, employed for the alter-
nate dissolving of the copper and zinc from the ore
by means of salt cake solution and hydrochloric acid.
This furnace should be constructed preferably on the
English or Tyneside pattern, and might be cither
two or three bedded, according to the production
intended. The tanks serving for the preparation of
the copper-zinc solutions should be connected by
automatic siphons with the third and fourth tanks of
the second terrace, which would take up the solu-
tions as soon as they have cleared sufficiently. From
these reservoirs the liquid may be conducted into
copper cylinders, kept in rotation by appropriate
machinery and filled with iron scraps — a contrivance
which will enhance the speedy precipitation of the
copper. Preferably, however, the recovery of both
metals present should be effected in the electrolytic
way, since the chemical methods serving for the sepa-
ration of the zinc only allow of the separation of that
metal in the form of oxide, and are rather tedious
and expensive.
Other points observed during the treatment of the
ore samples, as described above, were the following :
It was noticed, that the hydrochloric acid did not
display the selective capacity for copper and zinc to
the same degree as salt or nitre cake solution, and
that, therefore, the liquids obtained by means of that
solvent, contained a greater amount of iron than
those resulting in the other way. The presence of
the latter does, however, not prevent the successful
precipitation of the copper, but seems to interfere
to some extent with the recovery of the zinc in the
quantities desired. It may, therefore, be neces-
sary, in case the iron contents predominate largely,
to remove them, after the electrolytic precipitation
of the copper has been accomplished, so as to obtain
a solution containing practically no other ingredients
than zinc salts. It was found that this end could be
readily obtained, and in an inexpensive manner, by
precipitating the iron with lime, and subsequently •
electrolyzing the remaining clear solution.
Furthermore, it was observed that the introduc-
tion of gaseous hydrochloric acid into the water
added, caused a gradual heating of the liquid, so
that some lead, present in the samples, entered into
the solution as chloride, whioh separated out on cool-
ing in the form of a white precipitate.
Though the chemical principle, upon which the pro-
cesses mentioned are based, was not realized unto the
present — that is, the action of nitre cake or salt cake
in aqueous solution upon pulverized copper and zinc
ore — yet the selective capacity of sodium sulphate at
higher temperatures has been taken advantage of in
smelting operations years ago. In England espec-

ially the applicability of sodium sulphate for the sep-
aration of zinc from silver and lead in ores carrying
these three metals has been realized, and a very effi-
cient process established accordingly. Large works
of this character are at present in operation there,
and the results obtained argue very favorably for the
extended utilization of this inexpensive and rather
neglected or overlooked material for smelting pur-
poses. This remark is especially true for that in-
dustry as carried on in the United States.
In the process under consideration the zinc contents
of the ore pass into the slag, while the silver and
lead settle in the bottom of the crucible or furnaces
employed in the form of bullion. The zinc contents
of the slag are recovered by roasting, when the
metal volatilizes as zinc oxide, and is condensed in
properly constructed flumes, while the separation of
silver from the lead, which represents the final step
of the operation, is then effected in the usual manner.

NUMBER II.— CONCLUDED.
The following is a simple method for determining
the dip of exposed strata with sufficient accuracy for
practical purposes :
In Fig. 1 let P Q D C represent the surface of an
inclined stratum. It is required to determine the
direction in which it dips, and the angle at which it is
inclined.
If a plumb-bob is suspended from a partly open
rule, as shown in Fig. 1, and the open ends of the rule
be turned in the direction of the dip until the plumb-
line forms one side of a triangle with the two limbs of
the rule, then the lower limbs G H will lie in the
direction of the dip ; for the plumb-line will only com-
plete the triangle with the limbs of the rule when its
lower limb is placed on I K, the line of greatest in-
clination of stratum P Q D C. This can be seen bv
Fig. 1.
Diagram illustrating method of determining dip
of exposed strata.
turning the rule so that limb G H falls on line L M
or N O, neither of which is the line of greatest in-
clination of the stratum. It will then be seen that,
while the limb G H is in either of .these positions, or
any other position except the one which coincides
with the line I K, the plumb-line and the limbs of the
rule will not form a triangle.
If E F, the upper limb of the rule, be placed in a
horizontal position and the lower limb G H on I K,
the line of greatest inclination, the side of the triangle
formed by the plumb-line will be opposite the angle of
the dip. The value of this angle may be found from
the two sides of the triangle formed by a portion of
the upper limb of the rule and the plumb line.
The angle of the dip may also be ascertained with
approximate accuracy by carefully laying the rule,
opened as explained in the preceding paragraph, on
a piece of paper, drawing the angle and measuring it
with a protractor.
Some rules are furnished with a clinometer scale,
by which the angle formed by the open limbs of the
rule is indicated.
It will be apparent to mathematicians that, if the
upper side of the triangle be considered as radius,
the plumb-line will represent the tangent of the angle
of the dip; and if the hypothenuse, i. e., the lower
side of the triangle, be considered as radius, the
plumb-line will represent the sine of the angle of the
dip.
As previously mentioned, the strike is always at
right angles to the dip. Thus, in the case of stratum
P Q D C, if the direction of the dip, as shown by line
I K, is found to be S. 20° E., the strike will be repre-
sented by line P Q, at right angles to line I K, and
the stratum will extend in a horizontal direction with
a strike of S. 70° W., or N. 70° E.
Care should be taken that the surface of the
stratum, the dip of which is to be ascertained, really
is a bedding plane. It must be borne in mind that the
bedding planes are seldom true planes, as they are
subject to many inequalities.
Therefore, if possible, the dip should be estimated
at several places on the same stratum, and the aver-
age of the results taken as the dip. In estimating

the dip of a stratum of rock by this method, it is well
to clear off a space on the surface of the stratum and
to lay thereon a board, thus getting a better surface
on which to work.
When a remunerative oil-yielding stratum has been
discovered, its strike and dip should be determined
by drilling three wells according to the following
method :
In Fig. 2 let A, B and C be three wells in which the
oil sand has been struck at 100', 500' and 250', re-
spectively, below any datum plane, such as a hori-
zontal plane touching the top of well A. Draw A B,
and let it represent a horizontal distance of 600'. If
a point be found between wells A and B at which
the oil sand can be struck at a depth of 250' below
the datum plane, a line drawn from well C to that
point must necessarily be drawn along the strike of
the formation; and if a line be drawn at right angles
towards the strike of the formation and towards the
deepest well, that line will necessarily be drawn in
the direction of the dip of the formation. Moreover,
the figures contain the elements from which the angle
of the dip may be calculated.
The question is : At what point along the line A B
will a well strike the oil sand at 250' below the datum
plane ? The distance A B is 600'; the difference in
the depth of wells A and B is 400'; therefore, the
grade o£ the surface of the oil sand A and B is 400' in
600', or 2' in 3'. Hence, wells situated along line A B
and sunk to strike the stratum of oil sand, would, if
measured from the datum plane, increase in depth as
well B was approached, and the depths would be in
proportion to the distance from A measured along
AB.
It is required to find a point along the line A B at
which the oil sand may be struck 250' below this line,
or 150' deeper than at A. Since the increase in depth
of wells which may be sunk from the datum plane to
the oil sand along the line A B is at the rate of 2' in
depth to every 3' of horizontal advance toward B, the
distance from well A to the required point will be to
the increase of depth of well at the required point as
3 to 2, or li times 150', which is 225'. Lay off A D =
225'. As point D is 225' distant from well A, along
line A B, a well sunk at point D will strike the oil
sand at a depth of 250' below the datum plane. Hence
a line drawn from C to D will give the direction of the
strike of the oil sand stratum.
Or the proposition may be stated thus : The grade
of the stratum of oil sand between wells A and B is
400' (the difference between the depth of the wells at
A and B) divided by 600' (the horizontal distance be-
tween the two wells), which gives two- thirds of a foot
in depth to 1 foot along A B. Dividing 150' (the dif-
ference of depth of wells A and C) by two-thirds of a
foot, we obtain the distance 225', which is the distance
A D. Therefore, if a well were sunk at D, the oil
sand would be struck at a depth of 250'. Draw the
line C D. Now, it is evident that a well sunk at any
point along' C D would strike the oil sand at a depth
of 250'. Hence, as stated before, the line C D is the
direction of the strike of the oil sand stratum. More-
over, any line drawn at right angles to line C D, and
in the direction of the deepest well, will be drawn in
the direction of the dip of the formation.
It is now required to find the angle at which the oil
sand dips, and this can be found as follows: From B
draw B E at right angles to C D (the line of strike).
This line E B is the direction of the dip of the forma-
tion. By measurement, we find that line E B is 330'.
If a well were sunk at point E, it would strike the oil
sand at a depth of 250' below the datum plane.
Therefore, the grade along the surface of the oil sand
in the direction of E B is 250' in 330'; and this grade
represents an angle of about 37°. If the meridian be
represented by the arrow in Fig. 2, then the oil sand
penetrated by the wells A, B and C dips S. 80° E., at
an angle of about 37°, and, consequently, the strike is
N. 10° E.
When a remunerative stratum of oil sand has been
struck and the angle at which it dips has been ascer-
tained, as shown in the foregoing paragraphs, the dis-
tance from any of the wells, as B, to the point at
which the oil sand ought to crop out at the surface of
the ground, if it were on a level with the datum line,
can be determined. This is done by the following
method :
Let Fig. 3 represent a vertical cross-section drawn
through the ground plan of Fig. 2, along line B E,
and extended along the line of dip toward the out-
crop. Let B b represent 500', the depth of well B,
and let E e represent the depth of a well which, if
sunk at E, would strike the oil sand at a depth of
250', as explained in the preceding paragraph. It is
required to find the point at which the stratum of oil
sand, struck in well B, ought to crop out at the sur-
face of the ground, provided the surface were on a
level with the datum line and not covered with allu-
vium. Through points b and e, or the top of the oil
sand stratum, draw b e, and extend it until it cuts
the datum line; the point where it cuts this line is at
L. If the distance between B and L be measured, it
will be found to be about 660', which is the distance
Diagram illustrating method of determining dip
of oil sand stratum.
between well B and the outcrop. If the surface of
the ground sloped upward from the datum line, as in-
dicated by the outline H Y, it is evident that the oil
sand would crop out at a point above the datum line.
This point can be found by extending line b L till it
strikes the surface. It is obvious that if the surface
of the ground sloped downward from any point, such
as H on the datum line, the outcrop would be below
the datum line.
The angle at which the oil sand dips, and the dis-
tance from well B to the outcrop, may be found by
measurement and the simple methods already given,
with sufficient accuracy for practical purposes. But,
if a closer estimate is desired, it can be obtained by
the following trigonometrical formulas :
From the right-angled triangle a e b (see Fig. 3),
of which a e = 330' and a b = 250', we have :
Cot. of angle of dip (a e b) = 330' -=- 250' =
37° 8' 48".
From the right-angled triangle B L b, of which
B b = 500', and the angle a e b = angle B L b =
37° 8' 48", we have :
B L = 500' X cot. 37° 8' 48" = 660'.
That is to say, the distance from well B to the out-
crop at L, measured on the datum plane, equals the
depth of the well multiplied by the cotangent of the
angle of the dip.
If in the first instance an outcrop of oil sand had
been discovered at point F, and well B had been sunk
to strike it, then it becomes important to determine
whether or not the previously discovered outcrop of
the oil sand is identical with the outcrop of the oil
sand as determined by calculation. It has been found
that the angle of the dip would cause the oil sand
struck in well B to come to the surface at point L or
Y. Therefore, it is reasonable to suppose that the
discovered outcrop which comes to the surface at F
represents a stratum of oil sand underlying that pen-
etrated by wells A, B and C. (See Fig. 2.)
If an outcrop of oil sand had been discovered at F
and well B sunk, and oil sand had been discovered at
500', it would naturally be supposed that the oil sand
stratum discovered at point F had been reached. If
struck a little sooner than expected, it might be ac-
counted for on the ground that there is some irregu-
larity in the dip ; but when three wells are sunk and
the dip, calculated by the method of triangulation
already explained, shows that the stratum of oil sand
struck in wells A, B and C ought to appear at L or
Y, it is presumptive evidence that the outcrop of oil
sand discovered at F is a stratum underlying that
penetrated by the wells. When no outcrop of oil
sand has been discovered, it is important to find out
where the outcrop ought to be in order that some
idea may be had on the ground as to the width of that
portion of the oil line which lies between the well and
the outcrop.
In all these calculations everything must be reck-
oned with reference to a common datum, which is
preferably the horizontal plane passing through the
highest or lowest part of the oil field in which the
calculations are made. Oil fields should be developed
by this method of triangulation, or some modification
of it. In the development of an oil field in California
it is expected that many cases will occur where the
calculations will not tally with the results, for the
reason that there are irregularities in the formation;

but, taken as a whole, progress by triangulation is
the only safe method of procedure.
It will be evident to mathematicians that the cal-
culations herein set forth may be made by various
formulas.
From the foregoing paper it will appear that, al-
though the element of risk is inseparable from petro-
leum mining, it is greatly diminished by competent
and careful preliminary work, consisting of:
First.— A study of the structural features of the
locality wherein operations are to be conducted.
Second.— By following a systematic method of tri-
angulation for determining the strike and dip of the
oil sand, and the site of new oil wells.
When a remunerative oil line has been discovered,
it should be developed gradually ; in districts where
there has been much geological disturbance it is better
to limit the distance between wells to about 300'.
If oil lines are discovered on both sides of an anti-
clinal fold, it is well to develop them simultaneously,
by which means a correct idea as to the structure of
the fold may be obtained.
By prospecting and developing territory on the
lines mentioned in this paper, a few wells may be so
located as to demonstrate in most instances the value
of the territory; whereas wells drilled without due
regard to the geological conditions of the locality
demonstrate nothing more than the value of the rocks
they actually penetrate, and several wells may be
drilled which prove only the same fact instead of the
group of facts on which the value of an oil field de-
pends.
From the foregoing discussion it is apparent that
the depth of oil wells depends on the angle at which
the oil sand dips, and the distance the wells are from
the outcrop of the oil sand, or from the axis of the
fold or the fault line on which the wells are situated.
As a general statement, it may be said that the most
productive wells are about 1000' in depth, some being
much deeper.
The "life" and yield of such wells are naturally
varied. Some wells are " spouters " and "' start off "
by flowing several hundred barrels of oil a day, but in
most instances the flow subsides and the well becomes
an ordinary "pumping well." In some instances
wells have "started off" with a yield of 100 barrels
or more a day by pumping, but in the course of from
two to six years the yield has diminished to ten bar-
rels or less a day. In other instances the first yield
was less than 100 barrels a day, but the rate of pro-
duction was better sustained during the "life" of
the well. In some oil fields the wells are considerably
less than 1000' in depth, but, as a rule, their yield is
not so great as that of the deeper wells.
The cost of drilling wells varies according to the
accessibility of the locality where the well is situ-
ated, and the character of the formation pene-
trated.
The following statement as to the cost of drilling
1000', exclusive of the cost of casing, is a consensus
of opinion obtained by correspondence with several
well known oil producers :
Cost of
Locality. Drilling 1000'.
Los Angeles and the Kern River district. $1,000 to $3,500
The Puente Hills 3,500 to 7,000
Newhall and territory on the north side
of the valley of the Santa Clara river. . 5,000 to 7,500
The foothills of the Coast Ranges on the
west side of the San Joaquin valley 2,000 to 7,000
A review of the oil fields in the Coast Ranges leads
to the conclusion that the most favorable locality in
which to drill "prospect wells" is one wherein a
definite stratum of oil sand has been discovered in a
formation belonging to a geological horizon known to
include productive oil measures in other places ;
preferably there should be seepages of liquid petro-
leum at or near the locality in which prospect wells
are to be drilled, and the angle at which the oil sand
dips should not be more than 50° nor less than 10°.
The Burlap Process.
On page 610 an old resident gives a brief account
of the gold bearing gravel bars of the Snake river,
which winds between Oregon and Idaho. In further
mention of the manner in which the gold is saved, the
burlap process is worthy of note, as practiced by
many an old miner along the banks of that river.
The method is as follows : A short sluice carrying
a considerable stream of water is first prepared ;
attached to this there is an inclined table about
16 feet in width and from 10 to 20 feet in length.
Where the table is 20 feet in length it is usually
divided in its incline, that is, the first 10 feet adjoin-
ing the sluicebox is sharper in its incline than the
last 10 feet, which is almost level with the horizon.
There are flanges or a rim on each side of this table,
4 to 6 inches high, and through its center it is divided
by a partition board, leaving each half 8 feet wide.
On the first 8 feet of each length there is placed a
quicksilvered copper plate, and over this is laid a
sheet of burlap, usually of Manila bagging, firmly
stretched and secured, so as to give an even surface
to meet the current that is to pass over it. To the
sluice there are screens attached for catching the
coarse gravel and sand, and the gravel being shoveled
into the sluice the fine sand, magnetic iron and fine
gold particles soon reach the burlap sheet that is
spread over the table. The current carries forward
the sand and all lighter matter, and the short hair-
like surface of the burlap retains the gold and black-
sand. Some of the gold particles penetrate the bag-
ging aud are caught on the quicksilvered plates.
After exposure to the current for about twelve
hours or less, the water is turned entirely onto one
side, the burlap sheet on the other side removed and
carefully washed in a large vat filled with water,
where it is entirely freed of the particles of gold
and black sand which adhered to it on the table. It
is then replaced on the table, the current turned on
again and the burlap on the other side treated in
the same way. When the washings of these burlap
sheets have accumulated to a considerable quantity
in the vat, mercury is poured upon them and by
means of an agitator the mercury is forced over and
over and through the mass of auriferous black sand
until it has taken up every particle of gold. The
black sand or magnetic iron is then washed out and
the amalgam renewed, the free quicksilver separated
by forcing through felt or buckskin, and the remainder
separated from the gold by fire.
Ralston Divide, Placer County, Cal.
Written forihe Mining and Scientific Press by
A. Boriiead.x.
The Mining and Scientific Press devoted consid-
erable space in the issue of July 30, 1898, to the Ral-
ston Divide Gold Mining Co.'s pi-operty, in Placer
county, Cal. The following will give further informa-
tion regarding the work done during the two years
since:
The property embraces ninety claims, about 15
miles in length of the Ralston Divide, between Long
Cauyon and the Middle Fork of American river.
This divide is comparatively virgin ground, only suffi-
cient work having been done to prove the presence
of gold in many places; some of the old works date as
far back as the early days of California in 1850. Be-
sides the mining ground, the company acquired
several miles of ditches, the longest or Lambert
ditch being 25 miles in length, and starting from
a big dam on the American river at French
Meadows. Other ditches, like the Long Canyon
ditch, are 10 to 12 miles in length. There is a wagon
road between the Divide and Summit Station, the
highest point where the overland Pacific Railroad
crosses the Sierra Nevada mountains, at an elevation
of over 7000 feet.
The property belongs to the Ralston Divide G. M.
Co., a California corporation, representing a French
company — the Compagnie des Mines d'or du Long
Canyon— composed entirely of French capital, with
headquarters at Paris, 5 rue Scribe. The California
office is at 214 Pine street, San Francisco. The
directors are F. Chappellet, president; A. Bordeaux,
vice-president and manager ; H. W. Pulcifer, C. Ril-
lict, H. Fabrigue ; George W. Dixon, secretary.
Following is a full list of early hydraulic works on
the Ralston divide : Pat Goggins, extensive hydrau-
lic pit ; Vaughn, small pits and shaft ; Willard, small
pits and 500 feet of tunnels in bedrock and gravel ;
MacPherson, 500 feet of tunnels in blue gravel ; Mac-
Allister, small pits ; Ramsey & Poland, two hydrau-
lic pits, extensive; Blacksmith Flat, large pit;
Quartz Point and Quartz Flat, two extensive pits in
white gravel ; Marshall, Hillside and Red Cut, three
pits in blue gravel ; Ralston Pennsylvania mine, large
pits in upper blue and white gravels ; Diana, two pits
and two tunnels in white gravel.
The Long Canyon's bed has been hydraulicked be-
low Willard and below Blacksmith Flat.
From May, 1898, the following has been done :
At the Pat Goggins claim, 3500 feet of tunnels in
full gravel, and breastings ; output of $5000 during
the prospecting operations of 1899. Granite mine,
700 feet of tunnel in full gravel. Ramsey claim, 100
feet of tunnel in gravel. Blacksmith Flat claim, 100
feet of tunnel in gravel. Lynchburg claim, 3150 feet
of tunnels, partly in bedrock, partly in gravel. Red
Cut, 1000 feet of tunnels in blue gravel. Total, about
8500 feet of tunnels. Most of this development work
has been done in order to locate a deep gutter or
river channel inside the Divide ; but so far the chan-
nels have proved to be very wide and flat, except for
a few stretches of shallow and richer gravel. In or-
der to work profitably such wide channels, with no
special concentration of gold, it will be necessary to
operate on a large scale, rather than to try exten-
sive underground works by drifting. Piping under-
ground has been tried successfully in some places — in
El Dorado and Nevada counties. This is the case
when the gold is scattered over the full width and
height of the channel, with occasional pay leads, but
lacking in a concentration of gold in deep gutters, as
in many of the mines of Forest Hill Divide, in Placer
county.
Two of the mines are, and a third one may be,
equipped for producing this coming winter — Pat Gog-
gins, Lynchburg and Blacksmith Flat.
At the Pat Goggins an elevator will raise up the
gravel 40 feet high, as the ground is flat. The ditches,
reservoirs and pipe lines were completed last sum-
mer. The elevator, furnished by the Risdon Iron
Works of San Francisco, is able to pass 100 cars an
hour with a pressure of 300 feet and 600 inches of
water. As the gravel inside was proving good last
spring, work will be done by drifting at the same
time as by hydraulicking outside.
Lynchburg is equipped with derricks and giants
under a pressure of 350 feet of water. Ditches,
reservoirs, pipe lines are ready.
Blacksmith Flat cannot dispose for the present of
more than SO feet of pressure, but there is another
ditch to be completed next year, at which work was
started already last summer, that will give about 250
feet of pressure and large capacity of water. Sub-
sequently the other mines will be opened up and
developed according to the first results obtained. A

large undertaking like this cannot succeed without
large expenses, as everything is to be done in a new
and remote country. The locating of the Forest
Hill channels has entailed an immense amount of ex-
penses in prospecting tunnels by hundreds, and the
Ralston divide is scarcely less extensive than the
Forest Hill divide.
Channels. — The development works by tunnels,
and the different surveys have proved the existence
of and located two different kinds of gravel, which,
as it seems, belong to two different channels. So far
there are no indications of any deep and narrow
channels; on the contrary, all the gravel tunnels

met with only wide stretches of flat river beds,
between far distant and slow-grade rims. At the
same time, the depressions along the exterior contact
line of gravel and bedrock are of considerable length
with a corresponding depth pointing conclusively to
the sole existence of some broad outlets. As there
do not appear to exist any deep and narrow outlets
in any place all around the Divide, it is fairly probable
that there are no deep or narrow channels.
As both the white and the blue gravel belong to
some wide and flat channels, it would seem as if they
were two stratas in the same channel, and this opin-
ion was expressed in a report of W. Lindgren on. the
old Yuba and American river channels. The white
gravel is always at a slightly superior level above the
blue gravel, and might possibly be its upper lead,
now resting upon the cement, but now resting upon
the bedrock, thus proving to be an independent chan-
nel. In the Forest Hill Divide the same white and
blue gravels exist, with the same difference of level,
and yet, according to Ross Browne's map, their chan-
nels are different altogether ; the deepest one is the
youngest. According to W. Lindgren, on the con-
610

trary, the deepest one would be the oldest ; this is
adverse to the facts, as, for instance, the modern
rivers, being the youngest ones, have cut the deepest
bed across the bedrock.
I am disposed to believe that on the Ralston divide
the white and blue channels are different, but they
may have run parallel, and even between the same
rims in spme places, and this still better explains the
sole existence of very wide depressions of bedrock
along the,' contact line.
In the Forest Hill divide there is a similar phe-
nomenon, the parallel existence of a white and of a
blue channel, at a slightly different level. The white
Pond channel is different from the blue Mayflower
channel, and is considered to be the oldest one ; yet
they run close by each other, even with an intersec-
tion right below Forest Hill.
If there are no deep and narrow channels in the
Ralston divide, there may be some pay leads. Even
in the widest rivers there are generally some deeper
gutters, and such gutters in California are the regu-
lar channels of the miners, being the richest pay
leads. To locate them is a much more difficult task
than to locate the old river itself, and this was only
done in the Forest Hill divide many years later, after
the discovery of the auriferous gravels, and after
the hydraulicking of the inlets, outlets and break-
outs of the channels. Subsequently only to the dis-
covery of a gutter in these inlets and outlets was
it possible to discover a pay lead in a channel by tun-
neling across the bedrock, and by drifting. Drifting
always follows hydraulicking. The Mayflower rich
channel was detected after its very existence was
demonstrated at Bath and Dardanelles.
This last period has not yet been reached in the
Ralston divide, but the second period, the discovery
of a pay lead in a wide river bed, seems to have been
attained in the wide outk-i of the Pat Goggins blue
channel by drifting, f .tnilar work is now undertaken
at the Blacksmith claim. Elsewhere drifting under
ground will be possible only after the development
on a large scale of the big hydraulic mine at Lynch-
burg. There is a prosperous future for the Ralston
divide mines. When the hydraulic mines are ex-
hausted, then will start the drift mines.
It is exceedingly probable that the white and blue
channels of this divide are the upstream course of
the white and blue channels of the Forest Hill and
Georgetown divides, their connections being Ken-
tucky Flat and Michigan Bluff.
Before closing, I can not refrain from saying a few
words on the old theory of an ocean beach to explain
the California channels. An upheaval of the Sierras
has not been proven as non-existing, and an ocean
beach only seems able to explain certain difficul-
ties, like the close vicinity of the very wide channels
at North Bloomfield, Dutch Flat and Iowa Hill, some
running to the Yuba, some running to the American
river. The local miners and the geologists disagree
as to the course of these channels. We are still
far from knowing everything about the California
channels.
Eledric Power Transmission 153 Miles.
The Snoqnalmie Falls Power Company, of Seattle,
Wash., whose present 1200 H. P. hydraulic station
has been given previous mention herein, conducted
tests on the 13th ult., to show that electric trans-
mission of power could be made commercially practi-
cable at a distance as great as 153 miles. The exper-
iments occupied several hours, during which the
various services of the company were cut off; and
the three-phase transmission lines were connected up
in one continuous circuit commencing at the power
house, running to Seattle, back to the hills, then to
Tacoma and back again to the falls. The regular
transmission is 32 miles to Seattle and 44 miles to
Tacoma. In each case there are two circuits, one on
one side and the other on the other of the pole line,
arranged with a triangular spacing of 30 inches be-
tween wires.
The single continuous three-phase circuit 153 miles
long was composed of 58 miles No. 264 (diameter in
mils) aluminum wire, 4 miles No. 1 B. & S. G. medium
hard copper, and 51 miles No. 234 (diameter in mils)
aluminum wire, 36f miles No. 2 B. & S. G. aluminum
cable, 1J miles No. 3 B. & S. G. medium hard-drawn
copper and IS miles No. 0 medium hard-drawn copper.
The apparatus used consisted of a Westinghouse
1500-kilowatt three-phase generator, used for pro-
ducing the current, and a similar machine used as a
synchronous motor at the end of the circuit.
With the 153-mile circuit open at the incoming end,
the tests were made for charging it at different volt-
ages, the alterations (7200) being kept constant. It
was found that as the voltage increased the charging
current rapidly increased; that is, at 22,500 line
voltage it required 62 kilowatts to charge the line;
at 30,000 volts it required 112 kilowatts, and at 35,-
000 volts it required 180 kilowatts. With the step-
down transformers at the falls cut in and their sec-
ondaries open, it was found that the current re-
quired to charge the line increased ; that is, at 22,-
500 volts it required 76 kilowatts, and at 30,000 volts
it required 123 kilowatts. The voltage at the in-
coming end of the circuit, with charging current
only on the line, was 24,600 volts when the im-
pressed voltage was 22,500 volts, and 32,100 volts
when the voltage at the outgoing end was 30,000 volts.
Tests were also made to determine the different
amounts of charging current required at different
frequency, the voltage being kept constant at 30,000,
and it was found that at 6000 alterations 100 kilowatts
were required to charge the line, at 6600 alterations
105 kilowatts and at 7800 alterations 115 kilowatts.
The line was then tested for loss of power in trans-
mitting a non-inductive load consisting of the water
rheostat, at the falls at the end of the 153-mile cir-
cuit, and it was found that the line voltage out was
30,000, incoming 22,500, drop, 25%. The amperes per
phase at 1000 volts out was 624, incoming 554, loss,
11.2%. The total kilowatt outgoing was 1100, incom-
ing, that is, delivered into the water rheostat tanks,
723, loss, 34.2%. A test was also made for charging
current with the sub-station transformers at Seattle
and Tacoma and the lowering transformers at the
falls in circuit, but with secondaries all open, and it
was found that with the 30,000 volts out, there was
31,500 volts in. and it required 193 kilowatts to
charge the line.
A test was then made of operating a second gen-
erator as a synchronous motor at the end of fthe 153-
mile circuit, and the machines were synchronized
without any trouble whatever, but soon began pump-
ing so that it was found advisable to separate the
machines. The experiment was then tried of opera-
ting the water rheostat and the synchronous motor
in multiple at the end of the 153-mile circuit, and the
performance of the motor was very much improved.
The water was then shut off from the water wheel
and the driven motor immediately reverted to a gen-
erator driven by its own inertia; the current in the
lines were reversed and the first generator became
in turn a motor and ran at the other end of the 153-
mile circuit until the inertia was expended.
Gold in Snake River Gravel Bars.
Written for the Mining and Scientific Press by
Wm. h. Washburn.
The gravel bars of Snake river, in Idaho, Oregon
and Washington, have attracted attention for forty
years. Extending for hundreds of miles along this
river, from its headwaters to its junction with the
Columbia, these bars contain gold to the value of
from a fraction of a cent to several dollars per cubic
yard. The latter values are found in a very few
spots and of limited extent, and when discovered are
soon worked out by itinerant prospectors. Twenty
years ago these best spots were a favorite resort of
miners and prospectors in search of a grubstake, but
they have nearly all been long since exhausted, so
to what is to be found between these points.
The gravel ranges in size from fine sand to boul-
ders seldom larger than a man's head. The current
has a velocity of from 3 to 5 miles per hour. The
gold is very unevenly distributed throughout these
bars, being generally found in strata of medium
sized gravel, from a few inches to a few feet thick,
usually overlaid by from 2 to 10 feet of barren sand
or gravel. Below these strata the gravel may also
be worthless. Depth does not seem to cause any in-
crease in values; where the bedrock has been reached
at a few points on the rim it holds but little gold.
■ As a typical instance of values, on one claim I
found about 18 inches of gravel at water level, from
which I rocked from 75 cents to $2.50 per yard. It
was overlaid by about 8 feet of sand practically bar-
ren; the gravel below being afterward proven to
carry but little value. Another claim shows strata
of from 2 to 4 feet thick and about 150 feet wide by
about 300 feet long, carrying about 50 cents per
yard, also overlaid by about 6 feet of barren sand,
the underlay being barren for at least 6 feet to water
level. These figures are given to give a fair idea of
the pay streaks in general. There are open bars in
places with no overlay, and where the pay streak is
of sufficient depth they are generally preferred by
those engaged in dredging. There are many pay
streaks found some distance . from the river, but
usually under the conditions as to overlay above de-
scribed. In some places there are strata of
cemented gravel from 1 to 3 feet thick, but generally
it is absent.
It may be useful to note the conditions under which
these pay streaks are laid down, as indicated by the
open bars along the river. We find the gold is de-
posited along the short or inner side of the curves in
the course of the river. Any stratum of good gravel
in the opposite bank has evidently been laid down
at some previous time under the same conditions.
The accompanying sketch will show the occurrence
of gold more clearly. The colors are coarsest at the
head of the deposit, gradually becoming finer and
fewer, and spreading out below, until the gravel is
too poor to pay. As long as the river retains its
course the pay streak will continue to form as the
bar is extended from year to year, thus forming the
larger deposits. One old resident worked a certain
spot over for eleven consecutive years, a fresh de-
posit of gold being made by the annual June rise of
the river. The average size of the gravel, as well as
other signs, seem to indicate that the gold is only de-
posited where the current has a certain medium
velocity. The valley is from 3 to 10 miles wide, and
quite flat generally, the course of the river having
from time to time swerved from side to side across
its whole width. At the few points where the bends

that the man with a pan and rocker has slim picking
these days.
The source of the gold cannot, of course, be accu-
rately determined. The generally accepted theory
is that it is the finer particles from the placer de-
posits of tributary streams, its extreme fineness and
usually flattened shape permitting it to be trans-
ported hundreds of miles along with the sand and
gravel. In fact it travels much faster than the
in the river are made more permanent by rocky
banks, the pay streaks seem to be deeper and of
greater extent than elsewhere. I have prospected
bars on the Columbia river near Wenatchee and
Brewster, and found the gold to occur under sim-
ilar conditions, although it is a trifle coarser.
The gold above the mouth of the Boise river is
very fine, averaging about 1200 colors to 1 cent, and
is worth from $17 to $19 per ounce. Below the

larger sizes of the latter. Some claim that the vast
lava beds of southern Idaho (which are said to con-
tain a small amount of gold) have contributed the
greater portion of the values. In support of this
theory it may be said that, so far as the writer has
observed, fine gold is to be found in the streams
draining any extensive lava formation in a mining
country. Probably it has been derived from both
sources.
Our investigations having been made from a point
about 20 miles below Huntington, Or., to 50 miles
above Ontario, these remarks will be mostly confined
mouth of the Boise the gold .is not quite so fine, aver-
aging about 900 colors to 1 cent. The value is lower,
being from $14 to $16 per ounce. It is always asso-
ciated with black sand (principally magnetite) and a
heavy reddish gray sand made up of minute rubies
and other various colored crystals. When carefully
separated the black sand contains only a trace of
gold. Below Huntington, as far as I prospected, the
most of the gold is evidently of local origin, being
quite coarse, and nuggets of considerable size are
found, although the pure gold from above is still in
evidence in favorable spots.

lead and usually about 43% zinc ; and
these are produced mainly by the Mover
and others. The Iron-Silver, Ibex and
Monarch furnish the most of the dry
sulphides and the siliceous ores come
mainly from the Ibex and Penn. The
iron-silver ores in the main are supplied
by the Home group, Moyer and the
leasers on Tryer hill, while the Small
Hopes, A. M. & W. and Mab ship most
of the lead sulphides. The carbonates
come in the main from the various prop-
erties on Carbonate hill. The Modoc,

MINERAL COUNTY.
The Big Kanahwa Leasing Co., opera-
tors of the United mines, snipped about
1000 tons of ore from the latter in Novem-
ber. The main shaft is 1175 feet deep,
and it is the purpose to sink 300 feet
deeper to the level of the Wooster tunnel,
by which the mine is to be drained. The
ores are lead sulphides, carrying gold and
lead values. They seem well adapted to
concentration, and plans are being made
for a concentrating mill, to be located near
the mouth of the Wooster tunnel, the ore
to be sent out through the latter. The
vein on this property ranges from 8 to 12
feet wide. This is the same vein which
passes through the Commodore, Bachelor,
Amethyst and Park Regent. To a depth of
400 to 500 feet the ores were siliceous and
high in silver, with no lead; and at greater
depth the silver values disappear, the ores
being a lead sulphide, with good gold
values.

been made, but the ores are specially
suited to concentration and the intentions
are to erect a mill for this work. The
Last Chance ore body is the same as that
so well opened on the Hill Top, in the
same locality. The vein on the latter is
phenomenal, in one place the workings
showing the ore to have been taken out
to a width of 15 to 40 feet between walls
and 500 feet vertically, without timbers or
other support. About 1,000,000 tons of
ore have been mined from the Hill Top.

Books Received.
Practical Coal Mining, 8vo., pp. 462, Geo.
L. Kerr, London ; Chas. Griffin & Co.,
Ltd., Philadelphia, J. B. Lippincott Co.,
of value to British colliery engineers, with
some general formulas of universal appli-
cability, but of little practical avail as a
whole to American workers. The book
has over 500 illustrations.
Water Power, 8vo., pp. 563, Jos. P.
Frizell, London, Chapman & Hall ; New
York, Jno. Wiley & Sons. This is one
of the most valuable books on the sub-
ject received during the year. The con-
tents are of an unusually high order of
merit, and admirably arranged. There
are twenty-five chapters, any one of
which are worth the price asked for the
book. The discussion of dams, develop-
ment of natural water power and hydrau-
lic motors are particularly good. The
author of this book had something to
say, said it, and quit when it was said.
Minerals and Mining of New Zealand,
1900 ; printed by the Government at
Wellington, 4to., pp. 250, with accom-
panying maps, somewhat after the fashion
of the biennial reports that used to be
issued by the California State Mining
Bureau, and of the same high order of
usefulness. There is much valuable in-
formation, carefully prepared statistics,
and elaborate tabulated details. Some
of the items sound singular to an Amer-
ican reader, as, for instance, five pages
of small type, "List of mine managers,
battery superintendents, and engine
drivers who have obtained certificates."
The book is an epitome of New Zealand's
mining industry, and shows growth and
increase therein.

Notices of Recent Patents.
Among the patents recently obtained
through Dewey, Strong & Co. 's SCIEN-
TIFIC Press U. S. and Foreign Patent
Agency, the following are worthy of spe-
cial mention:
Design for Horseshoe Pad.— No.
33,691. Dec. 11, 1900. J. Ewing, San
Francisco, Cal. This invention relates to
a novel construction of elastic pad which
is adapted to be attached to horseshoes to
form a resilient bearing for the weight of
the horse. It consists of a crescent-shaped
block having a thin, flat plate with curved
edges and the rear formed with a solid
block of greater thickness with divergent
annular ends to fill the space between the
heels of the shoe.
Bed Bottom Attachments.— No.
663,170. Dec. 4, 1900. John Hoey, San
Francisco, Cal. This invention relates to
an attachment for bed bottoms of that
class known as " wire " bed bottoms. It
consists in the combination with the side
rails and transverse bars of a bed bottom,
of a cap or housing for said bars including
a double series of parallel horizontal
flanges. One series of these flanges forms
a housing for the end bar, and the other
series forms a housing for the side rail,
said latter housing having its flanges ex-
tended beyond those of the other series.
Vertical transverse end flanges connect
the horizontal flanges, and the cap or
housing has a centrally located bridge or
extension for raising the end bars above
the side rails, and having an exterior
covering plate.
Face Steamer.— No. 663,574. Dec. 11,
1900. W. C. Keithly, San Francisco, Cal.
The object of this invention is to provide
a device by which the vapors of various
liquids may be brought into contact with
the face, or to be inhaled by the person
undergoing treatment. It consists of a
generator having an upwardly extending
wall at one side curved transversely, a
perforated chamber lying against this
wall, terminating short of the upper limits
thereof, the lower portion of this chamber
being in direct communication with a gen-
erating chamber, and a means for heating
the latter so that the vapor will pass
through the perforated wall. A flexible
hood or attachment is adapted to form a
closure for the upper part of the ap-
paratus and to enclose the head of the
patient so as to confine the vapors.
Draper-Slat Protector. — No. 664,-
054. Dec. 18, 1900. C. J. & T. T. Luckehe,
Gridley, Cal. This invention relates to a
means for protecting the transverse bars
or slats which are employed in connection
with endless traveling canvas or other
belts. It consists of a metal piece or cap
fitting upon and partially enclosing the
slat and having transverse and convex
corrugations or runners between which
the rivet is headed which secure the cap
and the slat together. This prevents the
wear which would ordinarily cut off the
rivets or their heads, so that they would
pull through and allow the parts to be-
come detached, the corrugations forming
a channel of sufficient depth for that pur-
pose.
Gold Separator.— No. 663,993. Dec.
18, 1900. W. W. M. Hickey, San Fran-
cisco, Cal. This invention relates to an
apparatus for separating gold from sand
and other material with which it may be
associated. It comprises an inclined
screen, an amalgamated plate below the
screen having riffles, a water tank, a chute
connected with the amalgamated plate
and inclining reversely thereto. In
connection with this is an amalgamated
drum or cylinder below the discharge end
of the chute which receives material
therefrom, and the material which is dis-
charged from the cylinder is received
upon a belt submerged within a water-
containing tank and traveling so as to
convey the material away continuously.
The belt passes around drums at opposite
ends of the tank and the cylinder is
driven by connections from one of these
drums. The screen, amalgamated plate
and chute are caused to reciprocate by
suitably connected mechanism, and by
means of a pumping mechanism the water
is raised continuously and discharged into
the upper part of the apparatus, the
pump being actuated in unison with
the movement of the other parts.
Comb Cleaner.— No. 664,030. Dec. 18,
1900. J. H. Wheeler, San Francisco, Cal.,
one-half interest assigned to Wm. Wilson
of same place. This device is intended to
clean combs, such as are used for the hair,
and to remove any dirt or obstruction
which ordinarily accumulates between the
teeth of the comb. It consists of a frame
or holder having parallel sides, wire coils
upon said sides and a wire or strand
wound around the sides and through the
interstices of the coils, so that the wire is
equidistantly fixed to form rows, the
wires of one row spacing intermediate
with the wires of the other. These rows
thus lying in parallel planes, it is only
necessary to press the comb upon them,
and they will pass between the teeth of
the comb and clean out any deposit which
may have been formed therein.
Bicycle.— No. 664,052. Dec. 18, 1900.
O. J. Lawry, Redding, Cal. This inven-
tion is designed to provide a relief for the
riders of bicycles by making the axles or
journals of the wheels and their bearings
movable in suitable guides, in the frame,
supporting said axles against the pressure
by springs of sufficient stiffness. The
forks of the frame have slotted inner
sides and the wheels are adapted to re-
volve between the forks, and are provided
with a guide interior to each member ex-
tending some distance above and below
their point of connection with the wheel
axle. Each of said guides has its upper
and lower ends slotted, one at right angles
to the other, and the slots are provided
with rollers adapted to travel in contact
with the inner walls of the forks so that
the movement will be easy and the axles
will not bind ; at the same time the wheels
will be kept in an essentially vertical posi-
tion between the forks. Above these
slides are sufficiently stiff and elastic
springs upon which the weight of the ma-
chine and the rider is carried. These
springs constantly yield to all obstructions
and irregularities of surface and thus form
a very easy riding machine.
Lock.— No. 664,245. Dec. 18, 1900.
J. A. Eastman, Fruitvale, Cal., assignor
to C. R. Eastman of same place. This in-
vention is designed to provide an im-
proved lock for doors, sashes and other
meeting parts. It comprises a locking
bolt or latch having its rear end con-
nected with a swinging link so that the

outer end or head of the latch may be
projected through the continuous slots In
the lock and the keeper, and mechanism
is provided by which the bolt is after-
wards depressed eo that its enlarged head
will be engaged with the keeper by a posi-
tive movement. A reverse movement of
the parts will lift the bolt and carry it
backward into the lock case which Is fixed
to one of the doors. The device thus
forms a very efficient means for securing
the parts together.

Regarding the buying of silver, Brad-
street's reports that the buying for East-
ern account in London has slackened
again, but the offerings are moderate, and
no accumulation of supplies of bars can be.
seen. Further buying orders for India
are expected to make their appearance
ere long, as trade conditions in that coun-
try are in a favorable state and the de-
mand for money for circulation is large.
The matter depends, however, to a large
extent on the ability of the Indian Govern-
ment to draw gold from Australia once
more.

WHAT THEY SAY:
Capt. C. S. Collins, 58 Broad St., N. Y., says:
" Its the bsst GOLD saver in the world."
GapS. H. R. Gillingham, Cid., N. C, says:
'Saves the minutest flout Gold, and after two
years' use am convinced it is the only machine
that will save float Gold."
Sam Keast, Supt. Buster mine, A. T., says.
" Will do perfect work and save all the Gold, fine
or coarse, with proper usage. We save Gold read-
ily that floats on water."
Earle C. Bacon, Engineer, N. Y., says: "Sam-
ples (concentrates) received and are finest work I
have ever seen in that line "
Dr. Thos. H Hicks, Expert in Gold and Silver
Treatment, Ft. Wayne, Ind., says: "That little
machine is a daisy. The fact that you readily
save values that Goat on water is to me the most
convincing argument against the wet system."
