... but don't get your hopes up about Buster contributing that much to this short. He was invited to participate by the short's actual star, Roscoe "Fatty" Arbuckle. That's not me calling Mr. Arbuckle names, but is actually his name in the credits of his films.
Fatty is an employee in a general store of the period, and he loves the proprietor's daughter, Amanda. The owner doesn't want Fatty anywhere near his daughter and sends her to a boarding school where men are not allowed and Amanda is only allowed mail from her parents. Fatty decides to dress up like Amanda's female cousin so that he can see her, but a fellow rival for Amanda, Slim (Al St. John), has a similar idea. So the store portion comprises the first half and the boarding school portion the second half.
This short is pure 1910's comedy with food fights, lots of flour throwing, and pants -kicking. Buster is just a guest star in all of this, with his main contribution being posing as a grocery store customer who comes in to get some molasses but winds up with it in his hat and stuck to his head and with it stuck to the bottom of his shoes so that he cannot walk.
Buster's role in the creative process of Arbuckle's shorts increased over the couple of years that they worked together such that, by the time of their last collaboration in "The Garage" in 1920, you can definitely see that Keaton's brand of gadget filled comedy and complex gags have won the day.
