Why are the objects left in the tree in Chapter 4 of To Kill a Mockingbird?
At first, Jem and Scout aren't really sure why the objects have been left in the tree, or who could have left them. After Scout finds the gum, it is Jem who discovers the new items: a pair of "scrubbed and polished" Indian Head pennies. They realize the objects probably don't belong to grown-ups, since "Grown folks don't have hidin' places." They decide that they must belong to a child who had placed them there before taking the bus to school. But until they discover to whom the items belong, it's "finders keepers." At this point, the children apparently do not believe that the gifts could possibly come from Boo, and the children soon become busy with a new form of entertainment: Their own imaginative play-acting version of the Radley family, known as the Radley Game.
