 The buffalo is a surprisingly stupid animal. |
| The Negro, however, has been tested on an extensive scale. |
| 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. |
| Although mountains may guide migrations, the plains are the regions where people dwell in greatest numbers. |
| The coast of British Columbia was one of the three chief centers of aboriginal America. |
| Year by year we are learning that in this restless, strenuous American life of ours vacations are essential. |
| 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. |
| 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. |
| The Indians could not undertake any widespread cultivation of the plains not only because they lacked iron tools but also because they had no draft animals. |
| 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. |
| Geologists are rapidly becoming convinced that the mammals spread from their central Asian point of origin largely because of great variations in climate. |
| America is the last great goal of these migrations. |
| Curiously enough man's body and his mind appear to differ in their climatic adaptations. |
| 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. |
