When boys reach puberty, the parents give a feast to the village. In the case of a girl, a feast is likewise given, and she occupies, for the duration of the menstrual period, a hut set apart for all the women in the village to occupy during their uncleanness. When it is over, she washes her clothes, and takes a bath, washing her head. This is just what every woman of the village always does. There is no mutilation, and the girl just changes her child's dress for that of a woman. The married women of the village assist at confinements. Twins bring good luck. Monsters are said to be sometimes born, bearing the form of little tigers, cows, monkeys, etc. On these occasions, the mother is said generally to die, but, when she does not die, she is said to eat the monster. Monstrosities must anyway be killed. Childless couples are dieted to make them fruitful, the principal diet for a man being plenty of black monkey, and for a woman a compound of various herbs and spices. A man may not marry the daughter of his brother or sister; he ought to marry his uncle's daughter, and he may have two or three wives, who may or may not be sisters. Among the plateau Muduvars, both polygamy and polyandry are permitted, the former being common, and the latter occasional. In the case of the latter, brothers are prohibited from having a common wife, as also are cousins on the father's side. In the case of polygamy, the first married is the head wife, and the others take orders from her, but she has no other privileges. If the wives are amicably disposed, they live together, but, when inclined to disagree, they are given separate houses for the sake of peace and harmony. With quarrelsome women, one wife may be in one village, and the others in another. A man may be polygamous in one village, and be one of a polyandrous lot of men a few miles off. On the Cardamom Hills, and on the western slopes, where the majority of the tribe live, they are monogamous, and express abhorrence of both the polygamous and polyandrous condition, though they admit, with an affectation of amused disgust, that both are practiced by their brethren on the high lands.
