- John Martindale: I was tryin' to dig this well when they came.
- Hopalong Cassidy: [grabbing a handful of soil and smelling it] You have any trouble diggin' this stuff?

- Hopalong Cassidy: This is why Trimble wants your ranch and all the other land in the valley.
- California Carlson: You mean that smelly stuff?
- Jimmy Rogers: What's it good for?
- Hopalong Cassidy: [laughs] There's a young fellah in the East can tell yuh. He's on his way to bein' the richest man in the world on account of it. His name is Rockefeller... John D!
- Hopalong Cassidy: Hold onto this land. Never sell Texas short. You know, what's under the ground might some day be more important to America than what's above it.
- Hopalong Cassidy: [being held under gunpoint by a vengeful Nolan] Well, why don't you get it over with?
- Sam Nolan: I'm waitin' for you to beg me not to kill yuh.
- Hopalong Cassidy: Don't make it would do much good now.
