Glanton and his boys ride out of the Yuma camp without getting into any major fights (a huge accomplishment at this point in the book). It looks like they've formed a plan with the Yumas to seize control of the ferry that's a little farther upriver.
Back at the camp, a woman scolds the travelling showman for putting his mentally challenged brother on display. The women take the brother down to the river to bathe him and they burn his cage to show that he'll be free from now on. They also give him a nice new suit of clothes.
Later that night, the brother wanders into the river and starts to drown. But the judge (who's just walking by) runs in and saves him.
