(M30) Among the Yaraikanna tribe of Cape York Peninsula, in Northern Queensland, a girl at puberty is said to live by herself for a month or six weeks; no man may see her, though any woman may. She stays in a hut or shelter specially made for her, on the floor of which she lies supine. She may not see the sun, and towards sunset she must keep her eyes shut until the sun has gone down, otherwise it is thought that her nose will be diseased. During her seclusion she may eat nothing that lives in salt water, or a snake would kill her. An old woman waits upon her and supplies her with roots, yams, and water.(100) Some tribes are wont to bury their girls at such seasons more or less deeply in the ground, perhaps in order to hide them from the light of the sun. Thus the Larrakeeyah tribe in the northern territory of South Australia used to cover a girl up with dirt for three days at her first monthly period.(101) In similar circumstances the Otati tribe, on the east coast of the Cape York Peninsula, make an excavation in the ground, where the girl squats. A bower is then built over the hole, and sand is thrown on the young woman till she is covered up to the hips. In this condition she remains for the first day, but comes out at night. So long as the period lasts, she stays in the bower during the day-time, but is not again covered with sand. Afterwards her body is painted red and white from the head to the hips, and she returns to the camp, where she squats first on the right side, then on the left side, and then on the lap of her future husband, who has been previously selected for her.(102) Among the natives of the Pennefather River, in the Cape York Peninsula, Queensland, when a girl menstruates for the first time, her mother takes her away from the camp to some secluded spot, where she digs a circular hole in the sandy soil under the shade of a tree. In this hole the girl squats with crossed legs and is covered with sand from the waist downwards. A digging-stick is planted firmly in the sand on each side of her, and the place is surrounded by a fence of bushes except in front, where her mother kindles a fire. Here the girl stays all day, sitting with her arms crossed and the palms of her hands resting on the sand. She may not move her arms except to take food from her mother or to scratch herself; and in scratching herself she may not touch herself with her own hands, but must use for the purpose a splinter of wood, which, when it is not in use, is stuck in her hair. She may speak to nobody but her mother; indeed nobody else would think of coming near her. At evening she lays hold of the two digging-sticks and by their help frees herself from the superincumbent weight of sand and returns to the camp. Next morning she is again buried in the sand under the shade of the tree and remains there again till evening. This she does daily for five days. On her return at evening on the fifth day her mother decorates her with a waist-band, a
