It will be noticed that the slat altar in Pl. XXV differs from that in Pl. XXIII. Both belong to the Knife Society and may be seen hanging side by side on the wall in the ceremonial chamber of the Quer´ränna, (Pl. XXVIII) which is also the official chamber of the Knife Society. The second was made in case of failure of the first. The vicar of this society is also ho´naaite and only surviving member of the Ant Society, and he, being anxious that the writer should see the sand painting of the Ant Society, prepared the painting for this occasion instead of the ho´naaite (Fig. 17). He also drew her a sketch of the painting of Ant Society for ceremonial held for the sick, which is here introduced (Fig. 18). This last may be described as follows: _a_ represents meal painting emblematic of the clouds, _b_ and _c_ bear-leg skins laid either side of it. The remainder of painting is in sand. _d_: Ant chief clad in buckskin fringed down the arms and legs; he carries lightning in his left hand; his words pass straight from his mouth, as indicated by a line, to the invalid _e_, who sits at the opening of the ceremonial to the right of the painting. The ant chief speaks that the malady may leave the invalid. A song of this character is sung by the members of the society. The invalid then passes to the front of the altar and stands upon a sacred Tusayan blanket (position indicated by _f_), when the ho´naaite and other members of the society proceed with their incantations over him, imploring the prey animals to draw the ants to the surface of the body. When the ants have appeared and been brushed from the body then a song is addressed to the eagle _g_ to come and feed upon the ants. When the ants have been eaten by the eagle the invalid will be restored to health. The two circular spots _h_ represent ant houses. These, with the paintings of the ant chief and eagle, are gathered into the blanket upon which the invalid stood and carried some distance north of the village and deposited. After the blanket has been taken from the chamber the meal painting is erased by the ho´naaite brushing the meal from each of the cardinal points to the center with his hand; he then rubs the invalid’s body with the meal, after which the members hasten to rub their bodies with it, that they may be purified not only of any physical malady but of all evil thoughts.
