A bit of the hair of the man he has killed is placed by his [ceremonial] "father" in a buckskin bag along with an owl feather to insure its blindness and a hawk feather to kill it, and by the ceremony this medicine is made subservient to his will. He embraces it, calling it "child," and uses it thereafter to bring rain. The whole ceremony is one for drawing the teeth of a dangerous power and freeing the perpetrator from curse, to the end that the power may be rendered beneficent.1
