Describe an incident from this chapter demonstrating that the children are learning the ways of the jungle.

The children soon learn that they can sneak onto trolley cars to avoid paying the fare. They feel this is fair since “Whose fault was it that at the hours when workingmen were going to their work and back, the cars were so crowded that the conductors could not collect all the fares?” They soon learn to whom they should sell papers and what parts of town to stay away from, and they begin to bring home money.
