Such restrictive prohibitions are directed in Melanesia against the relations of boys with their mothers and sisters. Thus, for instance, on Lepers Island, one of the New Hebrides, the boy leaves his maternal home at a fixed age and moves to the ‘clubhouse’, where he there regularly sleeps and takes his meals. He may still visit his home to ask for food; but if his sister is at home he must go away before he has eaten; if no sister is about he may sit down to eat near the door. If brother and sister meet by chance in the open, she must run away or turn aside and conceal herself. If the boy recognizes certain footprints in the sand as his sister’s he is not to follow them, nor is she to follow his. He will not even mention her name and will guard against using any current word if it forms part of her name. This avoidance, which begins with the ceremony of puberty, is strictly observed for life. The reserve between mother and son increases with age and generally is more obligatory on the mother’s side. If she brings him something to eat she does not give it to him herself but puts it down before him, nor does she address him in the familiar manner of mother and son, but uses the formal address. Similar customs obtain in New Caledonia. If brother and sister meet, she flees into the bush and he passes by without turning his head toward her[18]. On the Gazella Peninsula in New Britain a sister, beginning with her marriage, may no longer speak with her brother, nor does she utter his name but designates him by means of a circumlocution[19]. In New Mecklenburg some cousins are subject to such restrictions, which also apply to brothers and sisters. They may neither approach each other, shake hands, nor give each other presents, though they may talk to each other at a distance of several paces. The penalty for incest with a sister is death through hanging[20]. These rules of avoidance are especially severe in the Fiji Islands where they concern not only consanguineous sisters but group sisters as well. To hear that these savages hold sacred orgies in which persons of just these forbidden degrees of kinship seek sexual union would seem still more peculiar to us, if we did not prefer to make use of this contradiction to explain the prohibition instead of being astonished at it[21].
