So far as we can discern, the relations of primitive savages to the animal life about them is on the whole more friendly than is that of cultivated men. It is true that the savage looks to the creatures of the wilderness for the greater part of his needs. He slays them, not at all in sport, but for the profit they may afford. Moreover, in most cases, his imagination endows these wild creatures with a spirit like his own. He often adopts them, in his religious worship, placing his tribe under the protection of one or another, as some of our own people do themselves under the protection of particular saints. The effect of domestication when man comes to have his own separate estate in animal life is to separate men from the creatures of the wilderness. "Wild" and "tame" come to be terms having a meaning which the savage does not recognize, and this meaning has with the advance of culture become intensified, until to most men the only creatures entitled to protection are those which have been made subject to man. At first the process of domestication concerned only useful animals or plants, those which would take a part in our industries. Rapidly, however, these creatures have been adopted with the view to the aesthetic satisfaction which they might afford. Quite half of the number of species which have come under human control have been tamed mainly if not altogether because of the charms which they possess. If we reckon flowering plants in the category, by far the greater number of our captives have been brought to us because of their beauty. The work of domestication has in the main been effected by our own Aryan race. Out of the total number of animals and plants which have been made captives, probably more than two-thirds have been brought into subjection by the European Aryans or by the folk whom they have profoundly affected with their civilizing motives. The disposition to win goods from the wilderness is in effect a fair test of those qualities in a people which give them dominance: we may indeed roughly measure the qualities of diverse folk by a variety of conquests of this kind, which they have made. The reason for this relation is plain. Success, whether it be of the individual or of the race, depends in large measure upon forethoughtfulness, on a disposition to study as to where profit may be had, and intelligently to seek accessions of strength by experiments in domestication. Each of these winnings from the wilderness represented by our domesticated animals or plants has been painfully and laboriously gained. The men who did the tasks were not creatures of the day, but foresightful beyond the average of mortals.
