The rest of the school year passes grimly for Scout, who endures a curriculum that moves too slowly and leaves her constantly frustrated in class. After school one day, she passes the Radley Place and sees some tinfoil sticking out of a knothole in one of the Radleys’ oak trees. Scout reaches into the knothole and discovers two pieces of chewing gum. She chews both pieces and tells Jem about it. He panics and makes her spit it out. On the last day of school, however, they find two old “Indian-head” pennies hidden in the same knothole where Scout found the gum and decide to keep them.
