The whole history of life is a record of cycles.

Fertile soil, level plains, easy passage across the mountains, coal, iron, and other metals imbedded in the rocks, and a stimulating climate, all shower their blessings upon man.

Nevertheless most of the evergreen forests of the north must always remain the home of wild animals and trappers, a backward region in which it is easy for a great fur company to maintain a practical monopoly.

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.

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

Except on their southern borders the great northern forests are not good as a permanent home for man.

Curiously enough man's body and his mind appear to differ in their climatic adaptations.
