ALTAR OF KNIFE SOCIETY, PHOTOGRAPHED DURING CEREMONIAL.] The scenes on the third and fourth nights were coincident with those of the second, with a few variations. The man who sat between the ho´naaite and his vicar dipped the ashes with his plumes and sprinkled the altar, and, returning to his seat, the vicar laid the blanket and sprinkled the meal lines in the same manner as on the previous night; he also procured the child. When dancing before the altar two men wore bear-leg skins on their left arms, and two others wore them on their right arms. It was noticed that the skins were drawn over the arms upon which the amulets were worn. Their dancing and incantations were even more turbulent and more weird than on the two former nights. The songs the third night were addressed to the badger of the south and on the fourth to the wolf of the east. RAIN CEREMONIAL OF THE KNIFE SOCIETY. While the ho´naaite and his vicar sat during the morning making hä´chamoni they rehearsed in undertones the songs of their cult. The membership of this society consists at the present time of five men and two boys, and two novitiates, a man and a boy. The sun was far to the west when the members came straggling in and the ho´naaite proceeded to set up the slat altar (Pl. XXII_a_). Then each man took from the wall a soiled buckskin sack. The well-wrapped ya´ya was first taken out and then other fetiches. After the ho´naaite had unwrapped his ya´ya he prepared the sand painting in front of the altar (Pl. XXII_b_). The five ya´ya were stood on the line specially made for them and a miniature bow and arrow laid before each ya´ya. The ho´naaite then grouped fetiches of human and animal forms, then the medicine bowl containing water and a basket of sacred meal. He then drew a line of meal which extended from the slat altar to a distance of 3 feet beyond the group of fetiches, his vicar afterwards assisting him with the additional fetiches. Two stone cougars 2 feet in length each were stood up on either side of the group. A cougar 12 inches long, with lightning cut in relief on either side, and a concretion, were then deposited before the group. Bear-leg skins were piled high on either side of the altar. The cloud bowl and reed were added, the two flat baskets of hä´chamoni and plume offerings shown in the sketch were afterwards deposited upon the backs of the cougars. While this arrangement was in progress the minor members returned the powdered kaolin and black pigment to the ancient pottery vases, from which they had been taken to prepare the sand-painting.
