As the coasts of Labrador and Hudson Bay are ice-bound for a great part of the year, it is not likely that traffic by sea began there at any very early time; and consequently no particularly favourable conditions existed there for an early development of seamanship. Nor is this the case to any great extent on the east coast of North America farther south, which, with the exception of the Gulf of St. Lawrence, has little protection from the sea, and offers few facilities for coastal traffic.[53] Nor has it produced any other maritime people or any similar fishing-culture. Again, if the Eskimo culture had arisen there, it would be impossible to understand how they learned to use dogs as draught-animals. It is otherwise on the northern west coast of North America, which is indented by fjords and has many outlying islands, with protected channels between them and the land. Here seamanship might be naturally developed and form the necessary basis for a higher sealing-culture like that of the Eskimo. In addition there is abundance of marine animals which afforded excellent conditions for hunting. Here too we have many different peoples with maritime habits: on the one side the Eskimo northwards along the coast of Alaska; on the other side the Aleutians on the islands extending out to sea, besides Indian tribes along the coast of southern Alaska and British Columbia. Until, therefore, research has produced sufficient evidence for a different view, it must seem most natural that in these favourable regions with a rich supply of marine animals of all kinds we must look for the cradle of the culture that was to render the Eskimo capable of distributing themselves over the whole Arctic world of America. To this must be added that in these regions, by intercourse with people on the Asiatic side of Bering Strait, the seafaring Eskimo may have learnt the use of the dog as a draught-animal, which is an Asiatic, and not an American invention, and which is also of great importance to the whole life and distribution of the Eskimo in the ice-bound regions. We cannot here pursue further the inquiry into the still open question of the origin of the Eskimo and the development of their culture.[54]
