Many boys love this kind of realistic personal adventure. This one is unusually good -- a boy and his dog on a daring solo expedition by canoe and dog team in the wilds of Northern Canada, matching wits and skill against nature's hardships and furies. Since the expedition is ethnological in purpose, much tribal Indian lore is introduced. The adventure is exciting and there is a real feeling of the sweep and challenge of virgin country. Stories of this kind have a limited audience but an enthusiastic one.
