which were gifts to the song priest from the invalid, were gathered together by the song priest and carried by an attendant to the medicine lodge. An attendant erased the rainbow by sweeping his hand from the feet to the head, drawing the sands with him, which were gathered into a blanket and carried to the north and deposited at the base of a piñon tree. The song priest placed the wands in a basket, and thus, preceded by the invalid, carried them in both hands to the medicine lodge singing a low chant. The sweat house was not carelessly torn down, but was taken down after a prescribed form. Four men commenced at the sides toward the cardinal points, and with both hands scraped the sand from the boughs. When this was all removed the boughs were carefully gathered and conveyed to a piñon tree some 50 feet distant and fastened horizontally in its branches about 2 feet above the ground. The heated stones from the interior of the sweat house were laid on the boughs; the upright logs which formed the frame work of the house were carried to a piñon tree, a few feet from the tree in which the boughs and heated stones were placed, and arranged crosswise in the tree, and on these logs corn meal was sprinkled and on the meal a medicine tube (cigarette) was deposited. The tube was about 2 inches long and one third of an inch in diameter, and it contained a ball composed of down from several varieties of small birds, sacred tobacco, and corn pollen. It was an offering to Hasjelti. Meal was sprinkled on the tube. The ground on which the house had stood was smoothed over, the ashes from the fire carefully swept away, and thus all traces of the ceremony were removed. The invalid upon entering the lodge took his seat on the west side facing east. The song priest continued his chant. He took from the meal bag some sacred meal and placed it to the soles of the feet of the invalid and on his palms, knees, breast, back, shoulders, and head. At the conclusion of this ceremony all indulged in a rest for an hour or more. The bark cups which contained the colored sands for decorating were placed in the medicine lodge north of the door.
