The buffalo is a surprisingly stupid animal.

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.

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.

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.

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

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.
