To Kill A Mockingbird - Jem

Today Scout found some stuff in a tree knot-hole at the Radley house. We had no idea were it came from, but someone was definitely placing these things here. Scout had found some gum in it a couple days ago. We came up with the idea that we would keep the stuff we found in the knot-hole until school started again, them we would ask the kids if it was theirs. I thought that this was very weird. Who would put all this stuff in a tree knot-hole near the Radley house?
