The relation of the sexes is sufficiently explained by the mode of production. When these savages are on the march the woman carries the little that they possess, erects the tent, and searches for fruit; the man on the other hand by his natural qualities is fitted for hunting and for the defense of the hunting ground. Hunting being the principal resource, and in this period bodily strength being of the highest importance, it is natural that the man should rule. The so-called “higher hunters”, among whom we must reckon the North American Indians of the northwest coast and some peoples of northern Asia, have reached a higher stage of social evolution. The difference between these and the preceding class is only quantitative, and results from the circumstance that they have been able to settle themselves in countries that are rich in game and fish. This permits them to be more sedentary, to live in larger groups, and to attain a higher development. As with the lower hunters there is among them a division of labor between men and women: The man hunts, fishes, and constructs the tools that he has need of; the woman gathers roots and herbs, prepares the food, and gives herself up to the duties of the household. Some of these peoples are capable of producing more than they need, a fact which occasions commerce of some importance, and produces at times a great inequality of fortune. At this stage of development the woman is of great use, which brings it about that the father does not give his daughter but sells her. Since the man, then, has bought his wife she has become his property, and he can do with her as he wishes; her infidelity is punished with death. If the husband has received gifts of value from his father-in-law, he is a little limited in his power, since, if he wishes to repudiate his wife, he is obliged to return the gifts. However repudiation is rare, since the woman is very useful to the man and he has ordinarily paid very dear for her. This is also why polygyny, though permitted almost everywhere, is rare. Only the very rich can permit themselves the luxury of more than one wife. The position of the wife is rather better when, instead of following her husband, he comes to live at her father’s house. This happens sometimes when the man cannot pay the whole purchase price, sometimes when the father-in-law is much richer than he. In this latter case the son-in-law prefers to profit by the wealth and power of his wife’s father, who, for his part, asks nothing better than to keep his daughter at home, since, in this manner, instead of losing a worker from the household he gains one by the coming of the husband.
