"It was also a prescription of the ancient ritual code for females during this primary condition to eat as little as possible, and to remain lying down, especially in course of each monthly flow, not only as a natural consequence of the prolonged fast and resulting weakness; but chiefly as an exhibition of a becoming penitential spirit which was believed to be rewarded by long life and continual good health in after years. [Seclusion of Carrier women at their monthly periods; reasons for the seclusion of menstruous women among the Indians.] "These mortifications or seclusion did not last less than three or four years. Useless to say that during all that time marriage could not be thought of, since the girl could not so much as be seen by men. When married, the same sequestration was practised relatively to husband and fellow-villagers--without the particular head-dress and rings spoken of--on the occasion of every recurring menstruation. Sometimes it was protracted as long as ten days at a time, especially during the first years of cohabitation. Even when she returned to her mate, she was not permitted to sleep with him on the first nor frequently on the second night, but would choose a distant corner of the lodge to spread her blanket, as if afraid to defile him with her dread uncleanness."[237] Elsewhere the same writer tells us that most of the devices to which these Indians used to resort for the sake of ensuring success in the chase "were based on their regard for continence and their excessive repugnance for, and dread of, menstruating women."[238] But the strict observances imposed on Tinneh or Déné women at such times were designed at the same time to protect the women themselves from the evil consequences of their dangerous condition. Thus it was thought that women in their courses could not partake of the head, heart, or hind part of an animal that had been caught in a snare without exposing themselves to a premature death through a kind of rabies. They might not cut or carve salmon, because to do so would seriously endanger their health, and especially would enfeeble their arms for life. And they had to abstain from cutting up the grebes which are caught by the Carriers in great numbers every spring, because otherwise the blood with which these fowls abound would occasion haemorrhage or an unnaturally prolonged flux in the transgressor.[239] Similarly Indian women of the Thompson tribe abstained from venison and the flesh of other large game during menstruation, lest the animals should be displeased and the menstrual flow increased.[240] For a similar reason, probably, Shuswap girls during their seclusion at puberty are forbidden to eat anything that bleeds.[241] The same principle may perhaps partly explain the rule, of which we have had some examples, that women at such times should refrain from fish and flesh, and restrict themselves to a vegetable diet.
