When the ceremony at Niqotlizi was over he proceeded to a locality in Arizona called by the whites The Haystacks, from the peculiar appearance of the rock formations there. At The Haystacks another great ceremony, probably the second in importance of the Navajo rites, was to take place. Here he again encamped with the Indians and remained until the work of the shamans was done.

The ceremonial observances witnessed on this occasion are, collectively, called by the Navajo Klèdji-qaçàl, or chant of the night. They are called by the whites the Yàybichy dance, from the name of the principal masked character, Yèbitcai or Gebitcai, the granduncle of the gods. Like the hoshkawn dance, it has several days of secret rites with elaborate symbolic sand pictures and one night of public dances, less varied and interesting than those of the hoshkawn. Dr. Matthews was permitted to witness the whole performance and to take as many notes and sketches as were necessary.

From The Haystacks Dr. Matthews went to the Indian agency at Fort Defiance, Arizona, where he secured the services of one of the oldest and most learned (in their own peculiar lore) of the Navajo priests, and from him he obtained full explanations of all these rites and of the symbolism of the pictures and masked characters, with a complete recital of the long and elaborate myths on which the ceremonies depend, and the texts and translations of the very numerous songs which form the ritual of the ceremonies.

WORK OF DR. H. C. YARROW.

Dr. H. C. Yarrow, acting assistant surgeon U. S. Army, with the assistance of military details and supplies, in addition to the instruction and facilities provided by this Bureau, started, August 8, 1884, on an expedition into the Territory of Utah, with reference mainly to the exploration of burial mounds and the study of mortuary customs.

Near Choke Cherry Spring a burial cave was discovered, containing the skeletons of three persons, which were secured. Other skeletons, with contents of graves, were obtained near Willow creek; also, an interesting specimen of tree burial.

At Deep creek an explanation of the curious form of water burial was gained from a chief of the Gosiats, to the effect that the bodies of the turbulent and disorderly men of the tribe were thus disposed of to prevent the spirits of these objectionable persons from joining the rest of the tribe after death. Their bodies were sunk in springs and marshy places and kept down by sticks and stones, so that their spirits could never get out.

In the neighborhood of Fillmore a mound was excavated which afforded an admirable example of the beforementioned conversion of a dwelling into a sepulcher. The probability is that the deceased died in his house, which was made of adobe bricks, and that it was at once abandoned and the body left therein, the roof being first removed. The corpse was placed on the floor and covered with a paste of moist clay, on which were placed the mortuary gifts of weapons, utensils, and food. Cottonwood branches were then piled above and set on fire, thus baking the clay crust and charring the several objects. The whole structure had been covered, so that on first examination the hard surface of burnt clay, 18 inches below the loose earth, appeared to be the floor of a former dwelling.

In the whole of the expedition, which continued into the last days of September, much difficulty was experienced from the suspicion and consequent hostility of the Indians of the localities visited.
