Among the Hareskin Tinneh a girl at puberty was secluded for five days in a hut made specially for the purpose; she might only drink out of a tube made from a swan's bone, and for a month she might not break a hare's bones, nor taste blood, nor eat the heart or fat of animals, nor birds' eggs.[121] Among the Tinneh Indians of the middle Yukon valley, in Alaska, the period of the girl's seclusion lasts exactly a lunar month; for the day of the moon on which the symptoms first occur is noted, and she is sequestered until the same day of the next moon. If the season is winter, a corner of the house is curtained off for her use by a blanket or a sheet of canvas; if it is summer, a small tent is erected for her near the common one. Here she lives and sleeps. She wears a long robe and a large hood, which she must pull down over her eyes whenever she leaves the hut, and she must keep it down till she returns. She may not speak to a man nor see his face, much less touch his clothes or anything that belongs to him; for if she did so, though no harm would come to her, he would grow unmanly. She has her own dishes for eating out of and may use no other; at Kaltag she must suck the water through a swan's bone without applying her lips to the cup. She may eat no fresh meat or fish except the flesh of the porcupine. She may not undress, but sleeps with all her clothes on, even her mittens. In her socks she wears, next to the skin, the horny soles cut from the feet of a porcupine, in order that for the rest of her life her shoes may never wear out. Round her waist she wears a cord to which are tied the heads of femurs of a porcupine; because of all animals known to the Tinneh the porcupine suffers least in parturition, it simply drops its young and continues to walk or skip about as if nothing had happened. Hence it is easy to see that a girl who wears these portions of a porcupine about her waist, will be delivered just as easily as the animal. To make quite sure of this, if anybody happens to kill a porcupine big with young while the girl is undergoing her period of separation, the foetus is given to her, and she lets it slide down between her shirt and her body so as to fall on the ground like an infant.[122] Here the imitation of childbirth is a piece of homoeopathic or imitative magic designed to facilitate the effect which it simulates.[123] [Seclusion of girls at puberty among the Thompson Indians of British Columbia.]
