rarely available at any distance from the rocky rim. The result is that most of the court kivas are only partly depressed. This is particularly noticeable in a court kiva in Shumopavi, an illustration of which is given in Fig. 14. The mungkiva or principal kiva of Shupaulovi, illustrated in Pl. XXXIII, is scarcely a foot above the ground level on the side towards the houses, but its rough walls are exposed to a height of several feet down on the declivity of the knoll. The view of the stone corrals of Mashongnavi, shown in Pl. CIX, also illustrates a kiva of the type described. This chamber is constructed on a sharp slope of the declivity where a natural depression favored the builders. On the upper side the roof is even with the ground, but on its outer or southern side the masonry is exposed to nearly the whole depth of the chamber. At the north end of Shumopavi, just outside the houses, are two kivas, one of which is of the semi-subterranean type. The other shows scarcely any masonry above the ground outside of the box-like entrance way. Pl. LXXXVIII illustrates these two kivas as seen from the northeast, and shows their relation to the adjacent houses. The following (Fig. 21) illustrates the same group from the opposite point of view. _Access._--The last described semi-subterranean kiva and the similar one in the court of the village, show a short flight of stone steps on their eastern side. Entrance to the ceremonial chamber is prevented when necessary by the removal of the ladder from the outside, or in some instances by the withdrawal of the rungs, which are loosely inserted into holes in the side pieces. There is no means of preventing access to the exposed trap doors, which are nearly on a level with the ground. As a matter of convenience and to facilitate the entrance into the kiva of costumed and masked dancers, often encumbered with clumsy paraphernalia, steps are permanently built into the outside wall of the kiva in direct contradiction to the ancient principles of construction; that is, in having no permanent or fixed means of access from the ground to the first roof. These are the only cases in which stone steps spring directly from the ground, although they are a very important feature in Tusayan house architecture above the first story, as may be seen in any of the general views of the villages. The justification of such an arrangement in connection with the indefensible kiva roof lies obviously in the different conditions here found as compared with the dwellings. [Illustration: Fig. 21.
