Why is Jurgis proud?

Jurgis is confident that he can find employment on his own, and he goes to Brown’s, where he is immediately picked out of the line because of his size. One of the bosses asks him if he can “shovel guts,” and Jurgis, though he does not understand the English of the boss, accepts a job. The boss tells him he must show up at seven the next morning. Jurgis is ecstatic that he has found work so quickly.
