After washing there was no place to pour the water except out of the window onto the heads of the people in the streets, which is the proper place to throw everything that is not wanted.
Although mountains may guide migrations, the plains are the regions where people dwell in greatest numbers.
Although farming of any sort was almost as impossible in the plains as in the dry regions of winter rains farther west, the abundance of buffaloes made life much easier in many respects.
Year by year we are learning that in this restless, strenuous American life of ours vacations are essential.
Man could not stay there forever. He was bound to spread to new regions, partly because of his innate migratory tendency and partly because of Nature's stern urgency.
No part of the world can be truly understood without a knowledge of its garment of vegetation, for this determines not only the nature of the animal inhabitants but also the occupations of the majority of human beings.
We are learning, too, that the love of beauty is one of Nature's greatest healers.
Except on their southern borders the great northern forests are not good as a permanent home for man.
In fact, the history of North America has been perhaps more profoundly influenced by man's inheritance from his past homes than by the physical features of his present home.
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.
The evidence points to central Asia as man's original home, for the general movement of human migrations has been outward from that region and not inward.
History in its broadest aspect is a record of man's migrations from one environment to another.
Again and again, to be sure, on the way to America, and under many other circumstances, man has passed through the most adverse climates and has survived, but he has flourished and waxed strong only in certain zones.
Curiously enough man's body and his mind appear to differ in their climatic adaptations.
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.
