Twain's caravan stops at a fountain for a rest period on its way to Damascus. What observation does Twain make at this fountain, and how does it make him feel?

The group is once again surrounded by pitiful beggars, or as Twain calls them, "vermin." These people are so ill and hungry that they basically look like bags of walking bones. While the men eat, the beggars stare and make chewing motions with their mouths. This sight completely distresses Twain to the point where he must leave.
