170. In the east, where the picture is not inclosed by the rainbow, we see the forms of two birds standing with wings outstretched, facing one another, their beaks close together. These represent certain birds of blue plumage called by the Navajo çòli (_Sialia arctica_). This bluebird is of the color of the south and of the upper regions. He is the herald of the morning. His call of “çòli çòli” is the first that is heard when the gray dawn approaches. Therefore is he sacred, and his feathers form a component part of nearly all the plume sticks used in the worship of this people. Two bluebirds, it is said, stand guard at the door of the house wherein these gods dwell; hence they are represented in the east of the picture. 171. Here is an appropriate occasion to speak of a part of Navajo symbolism in color to which reference has already several times been made. In the majority of cases the east is represented by white, the south by blue, the west by yellow, the north by black; the upper world by blue and the lower by a mixture of white and black in spots. The colors of the south and west seem to be permanent: the south is always blue and the west is always yellow, as far as I can learn; but the colors of the east and north are interchangeable. The cases are rare where white is assigned to the north and black to the east; but such cases occur, and perhaps in each instance merit special study. Again, black represents the male and blue the female. 172. The THIRD PICTURE commemorates the visit of Dsilyi‘ Neyáni to Çaçò‘-behogan, or “Lodge of Dew” (paragraph 56). To indicate the great height of the Bitsès-ninéz the figures are twice the length of any in the other pictures, except the rainbows, and each is clothed in four garments, one above the other, for no one garment, they say, can be made long enough to cover such giant forms. Their heads all point to the east, instead of pointing in different directions, as in the other pictures. The Navajo relate, as already told (paragraph 56), that this is in obedience to a divine mandate; but probably there is a more practical reason, which is this: if they had the cruciform arrangement there would not be room on, the floor of the lodge for the figures and at the same time for the shaman, assistants, and spectators. Economy of space is essential; but, although drawn nearly parallel to one another, the proper order of the cardinal points is not lost sight of. The form immediately north of the center of the picture is done first, in white, and represents the east. That immediately next to it on the south comes second in order, is painted in blue, and represents the south. The one next below that is in yellow, and depicts the goddess who stood in the west of the House of Dew-Drops. The figure in the extreme north is drawn last of all, in black, and belongs to the north. As I have stated before, these bodies are first made naked and afterwards clothed. The
