The mud plaster that has been applied directly to the stone work of the interior of this kiva is very much blackened by smoke. From about half of the wall space the plaster has fallen or scaled off, and the exposed stonework is much blackened as though the kiva had long been used with the wall in this uncovered condition. The fireplace is simply a shallow pit about 18 inches square that is placed directly under the opening of the combined hatchway and smoke hole. It is usually situated from 2 to 3 feet from the edge of the second level of the kiva floor. The paving stones are usually finished quite neatly and smoothly where their edges enframe the firepit. [Illustration: Fig. 25. Ground plan of a Shupaulovi kiva.] [Illustration: Fig. 26. Ceiling plan of a Shupaulovi kiva.] Figs. 25 and 26 illustrate the ground and ceiling plans of the second kiva of the same village. In all essential principles of arrangement it is identical with the preceding example, but minor modifications will be noticed in several of the features. The bench at the katchina, or “altar” end of the kiva, has not the height that was seen in the mungkiva, but is on the same level as the benches of the sides. Here the sipapuh is at much greater distance than usual from the katchina recess. It is also quite exceptional in that the plug is let into an orifice in one of the paving stones, as shown on the plan, instead of into a cottonwood plank. Some of the paving stones forming the floor of this kiva are quite regular in shape and of unusual dimensions, one of them being nearly 5 feet long and 2 feet wide. The gray polish of long continued use imparts to these stones an appearance of great hardness. The ceiling plan of this kiva (Fig. 26) shows a single specimen of Spanish beam at the extreme north end of the roof. It also shows a forked “viga” or ceiling beam, which is quite unusual.
