The coast of British Columbia was one of the three chief centers of aboriginal America.

History in its broadest aspect is a record of man's migrations from one environment to another.

America forms the longest and straightest bone in the earth's skeleton.

Thus the races, though alike in their physical response to climate, may possibly be different in their mental response because they have approached America by different paths.

In America the most widespread type of forest is the evergreen coniferous woodland of the north.

With every throb of the climatic pulse which we have felt in Central Asia,, the centre of civilisation has moved this way and that. Each throb has sent pain and decay to the lands whose day was done, life and vigour to those whose day was yet to be.

For the source of any characteristic so widespread and uniform as this adaptation to environment we must go back to the very beginning of the human race.
