Among the Thompson Indians of British Columbia, when a girl attained puberty, she was at once separated from all the people. A conical hut of fir branches and bark was erected at some little distance from the other houses, and in it the girl had to squat on her heels during the day. Often a deep circular hole was dug in the hut and the girl squatted in the hole, with her head projecting above the surface of the ground. She might quit the hut for various purposes in the early morning, but had always to be back at sunrise. On the first appearance of the symptoms her face was painted red all over, and the paint was renewed every morning during her term of seclusion. A heavy blanket swathed her body from top to toe, and during the first four days she wore a conical cap made of small fir branches, which reached below the breast but left an opening for the face. In her hair was fastened an implement made of deer-bone with which she scratched herself. For the first four days she might neither wash nor eat, but a little water was given her in a birch-bark cup painted red, and she sucked up the liquid through a tube made out of the leg of a crane, a swan, or a goose, for her lips might not touch the surface of the water. After the four days she was allowed, during the rest of the period of isolation, to eat, to wash, to lie down, to comb her hair, and to drink of streams and springs. But in drinking at these sources she had still to use her tube, otherwise the spring would dry up. While her seclusion lasted she performed by night various ceremonies, which were supposed to exert a beneficial influence on her future life. For example, she ran as fast as she could, praying at the same time to the Earth or Nature that she might be fleet of foot and tireless of limb. She dug trenches, in order that in after life she might be able to dig well and to work hard. These and other ceremonies she repeated for four nights or mornings in succession, four times each morning, and each time she supplicated the Dawn of the Day. Among the Lower Thompson Indians she carried a staff for one night; and when the day was breaking she leaned the staff against the stump of a tree and prayed to the Dawn that she might be blessed with a good husband, who was symbolized by the staff. She also wandered some nights to lonely parts of the mountains, where she would dance, imploring the spirits to pity and protect her during her future life; then, the dance and prayer over, she would lie down on the spot and fall asleep. Again, she carried four stones in her bosom to a spring, where she spat upon the stones and threw them one after the other into the water, praying that all disease might leave her, as these stones did. Also she ran four times in the early morning with two small stones in her bosom; and as she ran the stones slipped down between her bare body and her clothes and fell to the ground. At the same time she prayed to the Dawn that when she should
