School continues; the year goes by. Scout doubts that the new educational system is really doing her any good - she finds school boring and wishes the teacher would allow her to read and write, rather than ask the children to do silly activities geared toward "Group Dynamics" and "Good Citizenship." One afternoon, as she runs past the Radley house, she notices something in the knot-hole of one of the oak trees in the front yard. She investigates further and finds two pieces of chewing gum. Scout is careful, but eventually decides to chew them. Upon learning she is chewing found gum, Jem makes her spit it out. Later, toward the end of the school year, Jem and Scout find two polished Indian-head pennies, good luck tokens, inside the same knothole. The children don't know if the knothole is someone's hiding place or if the pennies are a gift, but decide to take them and keep them safely at the bottom of Jem's trunk.
