Among the Bantu tribes a man has the refusal of all the younger sisters of his wife as they attain puberty. Practically no woman lives unmarried all her life, for if no suitor seeks her, she singles out a man and offers herself to him at a reduced price, an offer usually accepted, as the women are excellent agricultural laborers. The Nilotic Kavirondo incline to exogamy, endeavoring always to marry outside their clan. Girls are betrothed at six or seven, and the husband-elect continually makes small presents to his father-in-law-elect till the bride reaches womanhood. It is regarded as shameful if the girl be not found a virgin on her wedding day. She is sent back to her parents, who have to return the marriage price, and pay a fine. The wife's adultery was formerly punished with death, and the capital penalty was also inflicted on young men and girls guilty of adultery. Among the Bantu Kavirondo the usual minimum price for a wife is forty hoes, twenty goats and one cow, paid in installments. The Nilotic Kavirondo pay twenty sheep and two to six cows; the husband-elect can claim his bride after half payment; if a woman dies without bearing children, the amount of her purchase is returnable by her father, unless the widower consents to replace her by another sister. The women are prolific and the birth of twins is common and considered a lucky event, which is celebrated by feasting and dances. Among the Bantu Kavirondo the mother of twins must remain in her hut for seven days; among the Nilotic Kavirondo the parents and the infants must stay in the hut for a whole month. If a Bantu mother has lost two children in succession, the next child born is taken out at dawn and placed on the road, where it is left till a neighbor, usually a woman friend who has gone that way on purpose, picks it up and takes it to its mother who gives a goat in return; a somewhat similar custom prevails among the Niotic tribes. Names are not male and female, and a daughter often bears her fathers name.
