The population is divided into two clans--the Bule and the Tabi. The former is supposed to have originated from the tridacna shell, the latter from the taro. Every individual knows exactly to which clan he belongs, although there are no external signs. There is a strict rule forbidding marriage within the clan, and an offence against this law was formerly punished by death; to this day, even in Christian districts, marriage within the clan is extremely rare. No one can change his clan. Children do not belong to the clan of the father, but to that of the mother, and property cannot be alienated from the clan. The father has no rights over his children, and the head of the family is not the father, but the eldest brother of the mother, who educates the boys and helps them along in the Suque. Land belongs to the clan, which is like a large family, and indeed seems a stronger organization than the family itself; but the clans live together in the villages, and as such they form a whole with regard to the outside world. Quarrels between two clans are not so rare as those inside a clan, and the vendetta does not act inside the clan, whereas a murder outside the clan must be avenged. Uncles and aunts within the clan are called father and mother, and the cousins are called sister and brother.
However, this exogamic system could not prevent inbreeding, as there was always the possibility that uncles and nieces might marry, so that a "horizontal" system was superimposed across this "vertical" one, forbidding all marriages between different generations. Thus, all marriages between near relations being impossible, the chances to marry at all are considerably diminished, so that nowadays, with the decreased population, a man very often cannot find a wife, even though surrounded by any number of girls. I do not mean to imply by this that the whole clan-system was organized simply to prevent inbreeding.
As I have said before, young men, as a rule, either cannot marry, being too poor to buy a wife, or, at best, can only afford to pay for an old widow, a low-priced article. The young, pretty girls are generally bought by old men, who often buy them when children, paying half the price down, and waiting till the girl is of marriageable age. As soon as she is old enough, she has to work for her future husband, and is under the care of one of his wives. Later on, the husband pays the rest of the money, builds a house for the girl, and the marriage takes place without any ceremony beyond a dinner to the nearest relatives of the couple. In most islands the girl cannot object to a match otherwise than by running away from a disagreeable husband. Generally, when she has run away several times, and repeated beatings have not changed her mind, her parents pay back the money and the husband gives up his wife. What is valued highest in a woman is her capacity for work; but the young men have a marked taste for beauty, and there are girls that are courted by all the young fellows of the village, and who, although married to an old man, accept the addresses of a young one. The husband does not seem to mind much, provided the woman continues to work well for him.
