There once was an old medicine man who, guided by a dream, led his tribe from Greenland across Baffin's Bay to North America. The tribe was increasing rapidly and there was great scarcity of food, and he dreamt about a further country with an abundance of seals, whales, walruses and other food--a land of plenty. The whole tribe believed him and they started over the ice. Halfway over, certain old men began to doubt, as is always the case: is the vision right or wrong? So half the tribe turned back, only to perish, while he went on with the other half and reached the North American shore.
