     The social organization of the Trobriand Islanders of Melane-
     sia is characterized by matrilineal descent, free and familiar rela-
     tions between father and son, and a marked antagonism between
     maternal uncle and nephew.³¹ On the other hand, the patrilineal
     Cherkess of the Caucasus place the hostility between father and
     son, while the maternal uncle assists his nephew and gives him a
     horse when he marries.³²
