Sometimes sickness came upon a member of Tokulki’s camp, and then Tokulki’s mother’s younger brother, who was doctor of the band, and at the same time Medicine Maker of the town, would be called in. Before prescribing, such a doctor often consulted the kila, or “knower,” who seems to have combined the functions of prophet and diagnostician, but Tokulki’s uncle never did this because he united the two functions in himself. Having determined the nature of the disease, he would go in quest of various herbs, or sometimes send members of the household after them. These he put into a great pot, poured water over them, and placed the pot over the fire. After the contents were sufficiently heated, he gave it potency by breathing into it through a hollow cane, while repeating a magical formula. This was done four times, the doctor meantime facing east. Sometimes, however, he prescribed sweat bathing in a lodge made of blankets thrown over poles, and containing heated rocks on which water was poured, and sometimes he declared the trouble was caused by witchcraft which he proceeded to cure by sucking the witching object out of the affected part by means of a bison horn.
