How is Amos willing to help Samuel George, the cobbler in Keene, who buys his leather?

What chapter are you referring to? In Keene, Amos went to find the cobbler to whom his leather was consigned. The cobbler was quite impressed with Amos's work and said how he wished such a good tanner lived closer to Keene. The closetclosests tanner was not very good. Amos saw this wish as a sign that he should move to Jaffrey, the small community he had passed a few miles back.

When the cobbler went to pay Amos, he complained that this was the last of his money. Amos gave back more than half the money in exchange for the cobbler's church clothes, which he had long outgrown. In November, Amos wore the fancy clothes, when he bought Violet and Celyndia's freedom. He and married Violet the next day.
