ancestors of the giraffe doubtless had neck and forelegs of ordinary length, like an antelope. It was a grazing or browsing animal. Its habitat is a land subject to severe droughts, so that occasionally all herbage except the tall, deeplyrooted trees is dried up. In such cases, if these short-necked grazing and browsing animals could not reach the leaves of tall shrubs and trees, they must perish. But if some happened to have little longer necks or forelegs, or both, it can readily be seen that they could survive the longest, because they could reach the highest. These fortunate survivors would be the only ones left to perpetuate their species. By the law of heredity their offspring would tend to the possession of long necks and forelegs. Besides, these long necks and legs give the animal the ability to detect an enemy. So after many generations, during which this selective process was going on, long necks and forelegs became the fashion in giraffe society.

This is what is meant by the terms, "Struggle for Life," "Survival of the Fittest," and "Natural Selection." Now it can be easily seen

that there is a steady tendency in nature to produce fitness or harmony between the organism and its world. Either the environment will modify the organism, or else the organism will modify the environment. To change the language, the aim of nature seems to be reconciliation, or at-one-ment, between the living creature and the great universe in which it lives, moves, and has its being. To be out of harmony with environment is the biological sin the wages of which is death.

Does this law operate in the human sphere? Doubtless. In primitive ages when man was barely man this biological law prevailed, and his body, according to the evolutionary theory, is the product of the forces that operate according to this law. When man ascended, by the evolution of his brain, into the world of mind, he was enabled to respond to new things in his environment. The moment he laid hold of the first tool or weapon, man entered upon a new world and a new era in his progress. The evolution of his body was arrested, the evolution of thought began.

using point of his bodily development there was little further need for adaptation to environment by changes in the mechanism of the body. Adaptation and change were now transferred from the body to the tool, and henceforth survival depended on the possession of the fittest tool or weapon-upon handiwork rather than upon the hand. Survival amidst unfriendly circumstances then depended not on adaptation of body, but upon the human mind; and the struggle for life under the law of selection was lifted into the realm of intellect.

The history of civilization is the story of that selection. Everywhere the races having the most mind have prevailed over the races of dull intellect. We are in the very midst of that process to-day. Aryans displaced the aborigines of India and of America because of superior mind. Greeks successfully resisted Persia not because of superior equipment or greater numbers, but because of higher intelligence. Rome crushed Carthage for the same reason. The American navy sunk the fleets of Spain in the recent war because the Yankees had keener in
