When Cole first found the log for the totem pole, what thoughts about escape kept creeping into his mind?

When Cole finds a huge washed-up pole, he decides to make a totem pole carving out of it. However, the log brings the possibility of making a canoe for escape, and Cole skips his morning soak in the freezing pond as he contemplates this possibility with anger in his heart for the first time since Edwin and Garvey departed.

On his next visit, Edwin sees that Cole had started to make a canoe but had instead crafted part of a totem pole, and Edwin is impressed that Cole has chosen the right course.
