How does Jurgis end up in jail again?

One evening, after knocking off from work early, Jurgis goes downtown where he has dinner and gets involved in gambling. He loses his money and then makes his way back home. On the way, he meets a prostitute who begins to take him into her house when a man with a lantern comes out and demands to know why there is such noise on the street. When the light reaches his face, Jurgis sees that it is Connor, the man who raped his wife. Jurgis becomes furious and begins to beat Connor again, smashing his head against a stone. A policeman comes over and beats Jurgis. The next day, in jail, Jurgis gets a five hundred dollar bail.

Because he has some money now, he calls Harper to help get him out of jail. When Jurgis tells Harper what he has done, Harper tells him that he cannot help him. Connor was a close friend of Scully’s and by beating him, Jurgis’s “pull had run up against a bigger pull, and he was down and out!” Harper negotiates the bail down to three hundred, which Jurgis pays, and he tells Jurgis that the only way to keep his freedom is to skip town. Jurgis boards a streetcar and makes his way to the other side of Chicago with only a few dollars left to his name.
