Several sticks, cut in zigzag shapes with curved appendages and short crossbars at one end, stand between the uprights of the reredos. From their forms, these objects may readily be identified as lightning symbols so common in all Tusayan altars. One of these, which has a complicated tip or head, is placed close to the outstretched arm of Cotokinungwu, with whom it is naturally associated. The straight rod leaning on the same arm is possibly a cornstalk symbol. The rounded stick, tapering at one end, which stands under the extended left hand of the image on the left, is probably a symbol of maize. A somewhat larger pointed object, painted at its base with zones of yellow, green, red and white, and surmounted by a feather, is called “the mound” and suggests the kaetukwi or Corn Mound of the Lalakontu, being similarly situated to an image on the left of this altar. The surface of the latter object, however, instead of being painted, is encrusted[5] with clay covered with different kinds of seeds. The crook at the extreme left of the altar has attached to it an object which resembles the paddle carried by a participant in the Heheakatcina, or public ceremonial of the Niman at Walpi. Four pahos, or prayer-sticks, are placed at intervals in hillocks of sand before the images on the altar. The Katcina tiponi,[6] or badge of the chief, stands on the floor before the altar. Just in advance of the left-hand idol—the image with a coronet—there is a small oblong basket in which are laid a number of sticks with feathers, seeds, and pinches of meal. This is called the “Mother,” and recalls similar objects which have been observed on the Lalakontu altar, whose contents have been described elsewhere.[7] I need not dwell on the other accessories of the Powamu altar at Oraibi save to note that they are common to other altars, and in no respect characteristic. I refer to the basket tray of sacred meal, the rattles, a medicine bowl, aspergill, and six ears of corn used in special rites. The strange object at the extreme right, surrounded by a tablet, symbolic of a rain cloud, bears the picture of the head of Ho’katcina. It is supported on a pedestal, and appears to be peculiar to Oraibi.[8] COMPARISON WITH THE NIMAN ALTAR AT CIPAULOVI Cipaulovi, the smallest of all the Hopi pueblos, is situated on the Middle Mesa, and its Katcina altar is the poorest in paraphernalia, as shown by a comparison with the altar at Oraibi, the most complicated in Tusayan.
