Tiyo made for himself a kind of coffin boat from the hewed-out trunk of a cottonwood tree. Into this he sealed himself and was committed to the care of the raging river. His rude boat dashed down the rapids, over the falls, into the secret bowels of the earth (for the Indians still believe the river disappears under the mountainous rocks), and finally came to a stop. Tiyo looked out of his peepholes and saw the Spider Woman, who invited him to leave his boat and enter her house. The Spider Woman is a personage of great power in Hopi mythology. She it is who weaves the clouds in the heavens, and makes the rain possible. Tiyo accepted the invitation, entered her house, and received from her a powder which gave him the power to become invisible at will. Following the instructions of the Spider Woman, he descended the hatch-like entrance to Shi-pá-pu, and soon came to the chamber of the Snake-Antelope people. Here the chief received him with great cordiality, and said:-- "I cause the rain clouds to come and go, And I make the ripening winds to blow; I direct the going and coming of all the mountain animals. Before you return to the earth you will desire of me many things, Freely ask of me and you shall abundantly receive." For a while he wandered about in the underworld, learning this and that, here and yonder, and at last returned to the Snake-Antelope and Snake kivas. Here he learned all the necessary ceremonies for making the rain clouds come and go, the ripening winds to blow, and to order the coming and going of the animals. With words of affection the chief bestowed upon him various things from both the kivas, such as material of which the snake kilt was to be made, with instructions as to its weaving and decoration, sands to make the altars, etc. Then he brought to Tiyo two maidens, both of whom knew the snake-bite charm liquid, and instructed him that one was to be his wife and the other the wife of his brother, to whom he must convey her in safety. Then, finally, he gave to him the "tiponi," the sacred standard, and told him, "This is your mother. She must ever be protected and revered. In all your prayers and worship let her be at the head of your altar or your words will not reach Those Above."
