Once you've finished the chapter, go back and look at
at the portion that describes Jem and Scout's snowman, which
is covered with white snow on the outside, but has a core of
dark mud. Symbolically connect the snowman to either Mr.
Avery (go beyond the "Morphodite's" physical similarity to
Mr. Avery) or Boo Radley. How could the snowman be seen
as a symbol for one of these men?
