How do Jem and Scout and find out that Boo Rdaley puts the presents in the knot-hole?

ok i cant exactly help u continue what ur writing...its a good article so far considering ur prob not in highschool yet, and if u are, then u should really work on your writting skills. um to kill a mockingbird wow that brings back memories of 8th grade. ok so what you should do is i know somewhere in the book (i cant remember the chapter) but it says the jem and scout looked down the street and Boo's older brother (cant remember his name) is filling up the knot hole in the tree. so i think scout asks jem why he is doing that if they only do that to dying/unhealthy trees. i think thats when they figure out or infer that its boo. also, it may not occur exactly in this context
