[KIVAS OR SACRED CHAMBERS]

The kivas, or estufas as they formerly were called, are sacred chambers in which the civil and religious affairs of the tribe are transacted, and they also form a place of resort, or club, as it were, for the men. Their functions are many and varied, but as this subject has already been discussed at length[17] it need not be enlarged upon here. In Tusayan the kivas are rectangular and separated from the houses; in Zuñi and in some other pueblos they are also rectangular, but are incorporated in the house clusters—a feature doubtless brought about by the repressive policy of the Spanish monks. In some of the pueblos, as in Taos, they are circular, and in many of the older ruins the same form is found. In the large ruins of Chaco canyon the kivas occur in groups arranged along the inner side of the rooms; always, where the ground plan is such as to permit it, arranged on the border of an inner court. In Canyon de Chelly the kivas are always circular and are placed generally on the outer edge of the settlement, which is usually the front.

As the function of the kivas is principally a religious one, they are found only in permanent villages where religious ceremonies were performed. They are never found in subordinate settlements, or farming villages, or outlooks, unless such settlements came to be inhabited all the year—in other words, until they became permanent villages. The habits and requirements of the Pueblo people make it essential that a permanent village should have one or more kivas, and we have in the presence of these structures a criterion by which the character of a village or ruin may be determined. As the kivas in De Chelly are always circular, they can generally be easily distinguished.

The circular kiva is unquestionably a survival in architecture—a relic of the time when the Pueblo people dwelt in circular lodges or huts—and its use in conjunction with a rectangular system entailed many difficulties and some awkward expedients to overcome them. The main problem, how to use the two systems together, was solved by inclosing the circular chamber in a rectangular cell, and this expedient aided in the solution of the hardly less important problem of roofing. The roof of the kiva was the roof of the chamber that inclosed it.

It seems to have been a common requirement throughout the pueblo country that the kiva should be wholly or partly underground. So strong was this requirement in Tusayan that the occurrence of natural clefts and fissures in the rock of the mesa top has dictated the location of the kivas often at some distance from the houses. But in De Chelly there were some sites where the requirement could not be filled without extensive rock excavation wholly beyond the power of the builders.

Here then it seems that other requirements were strong enough to overcome the ceremonial necessity for partly subterranean structures, for examples of that kind are comparatively rare. In all of the ruins on the canyon bottom the requirement could be filled, and as many of the villages on defensive sites were constructed after the site itself had been partly filled up with loose débris, it could also be filled in those cases. There are also instances where the bottom of the kiva rests directly on the rock, while outside the walls the site was covered deep with artificial débris. But it would be difficult to determine what was the surface of the ground when the kiva was in use.

The size and character of the kivas in De Chelly, and their relations to the other rooms about them, are shown in the ground plans preceding. Some have walls still standing to a height of 6 feet above the ground, but this could not have been the total height. Dr H. C. Yarrow, U.S.A., in 1874 examined one of the five large circular kivas in Taos. He states[18] that it was 25 or 30 feet in diameter, arched above, and 20 feet high. Around the wall, 2 feet from the ground, there was a hard earthen bench, and in the center a fireplace about 2 by 3 feet.

Entrance to the kivas is invariably from the roof by a ladder. This appears to be a ceremonial requirement. Doorways at the ground level are not only unknown, but also impracticable; but in De Chelly there are some puzzling features which might easily be mistaken for such doorways. The principal kiva in the ruin, which occurs at the point marked [10] on the map, and described above ([page 123], [figure 24]), is on the edge of the ledge, and its outer wall is so close as to make a passage difficult, although not impossible. At the point where the curved wall comes nearest the cliff there is a narrow gap or opening, not more than 15 inches wide. In front of this there appears to be a little platform on the sloping rock, 2 feet long, 10 inches wide, and now about a foot high. At first sight this would be taken for a doorway so arranged that access to the kiva could be obtained only from below; but a closer examination shows that this was probably only what remains of a chimney-like structure, such as those described later.

In ruin [31] there is another example. The kiva here was about 20 feet in diameter, with rather thin walls smoothly plastered inside. On the inner side the walls are from 3 to 5 feet high; outside they are generally flush with the ground. The kiva is not a true circle, but is slightly elongated north and south. On the south side, nearest the edge of the ledge, there is an opening, shown in figure 70. The opening is 6 feet 3 inches
