2. The next institution originating in scarcity of women is polyandry, a form of sexual relations which, by the adherents of the horde-theory, is regarded as the earliest type of the family, properly so called: a family resting upon marriage, that is, upon a courtship "of men and women, protected by public opinion."[243] It is of special interest, because in its progressive phases it is held to be the medium of transition from the maternal to the parental and agnatic systems of kinship; and, therefore, through the aid of contract in the form of wife-purchase, to modern conceptions of the marriage relation. Polyandry is represented as a universal phase of social evolution, constituting the first general modification of promiscuity.[244] Of this there are two principal forms with intermediate stages. In Nair[245] polyandry, the lowest type, we find a condition of sexual relations closely bordering upon the grossest communism. The "wife lives not with her husbands, but with her mother or brothers;" and, under certain "restrictions as to tribe and caste," she is free to choose her husbands or lovers, these not being necessarily related to each other. Here kinship and inheritance are, of course, in the female line. "No Nair knows his father, and every man looks upon his sister's children as his heirs."[246] In a transitional stage the wife has a home of her own, cohabiting with her husbands according to fixed rules. The highest type of polyandry is found in Tibet; and in this case there is a close approach to the essential elements of the modern family. The wife lives in the home of her husbands, who are near relatives, usually brothers. It is the prerogative of the eldest brother to choose the wife. All the children are assumed to belong to him, and, as a matter of fact, the first-born is usually known to be his. Paternity therefore is not entirely uncertain, while the father's blood is always known.[247] The same type of polyandry, somewhat more advanced, appears among the Dravidian Todas of India. Here monogamy and polyandry exist side by side. One man, for example, may have a wife exclusively his own, while his brothers may choose one in common. Usually when one brother has taken a woman to wife, and paid the dower to her parents, the other brothers or very near relatives, all living together, may gain the rights of husbands, "if both he and she consent," by simply providing their respective shares of the dower, which almost invariably consists of from one to four buffaloes.[248] According to Marshall, "no females, whether married or single, possess property; but, under all circumstances of life, are supported by their male relations, being fed from the common stock." When "a father dies, his personal property is divided equally among all his sons. If the deceased, being an elder brother, should have no sons, his next brother inherits all the property. All children of both sexes belong to the father's
