What are some of Jem's superstitions?

Each of the children believes, to some extent, the childish rumors about Boo Radley. Jem, Scout, and Dill spend much of the summer acting these rumors out, much to the chagrin of Atticus. Jem believes that touching Radley property equals death. Jem passionately stated, "Don't you know you're not supposed to even touch the trees over there? You'll get killed if you do!" Dill thinks Boo Radley died, and Jem says they stuffed his body up the chimney. All of this superstition feeds into Scout's already vivid imagination.
