Above that would come the food supply which is obtained from other sources. There is one which is not universal but still widely extended, and that is the pastoral life. There are many tribes (as, for instance, in southern Africa and in India and throughout the steppes of Tartary and elsewhere) who live on their herds and drive their herds from one pasture to another in order to obtain the best forage. This nomadic and pastoral life extended very widely over the old world in ancient times, but existed nowhere in the new world, for the simple reason that they had no domesticated animals. Our own remote ancestors—both the Aryans and the Semites—all the early ancestors of the white race so far as known, were pastoral or nomadic; and the Aryans of central Europe remained so until after the fall of Rome, when, for the first time, they became practically sedentary. This nomadic and pastoral life is a very great advance over the mere hunting and fishing stage. It requires considerable care and attention to domesticate the wild animals in any sufficient quantity to form a reliable source of food. Moreover, the attention which it was necessary to give to the rearing and training and the looking after domestic animals was to a certain extent, humanizing. When a man found that it was necessary to be careful about his animals, he would also be careful about his neighbors. We would say that the same sense which enabled him, or directed him, to look after the welfare of the herd would justify and, in fact, impel him to look after that of man also; so that the nomadic and pastoral life, although not stable nor favorable to the development of cities, nor the great extension of commerce, was nevertheless a decided advance over the ruder hunting and fishing stage. So far as we know, neither Aryan nor Semite ever depended upon a hunting and fishing stage. They doubtless did, but not in the time of any history that we know. The Bedouins, etc., wandering tribes to-day, and, among the Semitic, the Tuaregs of the Sahara, are a purely nomadic or pastoral race; yet are very much above the negroes of the south, who depend upon hunting and fishing.
