Concerning the system of polyandry as carried out by the Todas, Dr. Rivers writes as follows. "The Todas have long been noted as a polyandrous people, and the institution of polyandry is still in full working order among them. When the girl becomes the wife of a boy, it is usually understood that she becomes also the wife of his brothers. In nearly every case at the present time, and in recent generations, the husbands of a woman are own brothers. In a few cases, though not brothers, they are of the same clan. Very rarely do they belong to different clans. One of the most interesting features of Toda polyandry is the method by which it is arranged who shall be regarded as the father of a child. For all social and legal purposes, the father of a child is the man who performs a certain ceremony about the seventh month of pregnancy, in which an imitation bow and arrow are given to the woman. When the husbands are own brothers, the eldest brother usually gives the bow and arrow, and is the father of the child, though, so long as the brothers live together, the other brothers are also regarded as fathers. It is in the cases in which the husbands are not own brothers that the ceremony becomes of real social importance. In these cases, it is arranged that one of the husbands shall give the bow and arrow, and this man is the father, not only of the child born shortly afterwards, but also of all succeeding children, till another husband performs the essential ceremony. Fatherhood is determined so essentially by this ceremony that a man who has been dead for several years is regarded as the father of any children born by his widow, if no other man has given the bow and arrow. There is no doubt that, in former times, the polyandry of the Todas was associated with female infanticide, and it is probable that the latter custom still exists to some extent, though strenuously denied. There is reason to believe that women are now more plentiful than formerly, though they are still in a distinct minority. Any increase, however, in the number of women does not appear to have led to any great diminution of polyandrous marriages, but polyandry is often combined with polygyny. Two or more brothers may have two or more wives in common. In such marriages, however, it seems to be a growing custom that one brother should give the bow and arrow to one wife, and another brother to another wife."
