The ramifications formed by lateral rooms are often extensive, and the chambers communicate with others so dark that we can hardly regard them as once inhabited. In these dimly lighted rooms the walls were blackened with smoke, as if from former fires, and in many of the largest the position of fireplaces could plainly be discovered. As a type of one of the more complicated I have chosen that figured to illustrate the arrangement of these cavate dwellings (figure 245). Many are smaller, others have more lateral chambers, but one type is characteristic of all. A main room (_A_, figure 245), or that first entered from outside, is roughly rectangular in shape, 12 feet long by 6 feet wide, and about 6 feet high. The floor, however, was covered with very dry débris which had blown in from the exterior or, in some instances, fallen from the roof. That part of the floor which was exposed shows that it was roughly plastered, sometimes paved or formed of solid rock. On three sides of this room there is a step 2 feet high, to platforms, three in number, one in the rear and one on each side. These platforms are 5, 6, and 6 feet 6 inches wide, respectively, and of the same length as the corresponding sides of the central room. It would appear that these platforms are characteristic architectural features of these habitations, and we find them reproduced in some of the rooms of the cliff houses of the Red-rocks, while Nordenskiöld has described a kindred feature in the kivas of the Mesa Verde ruins. A somewhat similar elevation of the floor in modern Tusayan kivas forms what may be called the spectator's part, in front of the ladder as one descends, and the same feature is common to many older Hopi dwellings.[15] Beginning with the lateral platforms (_B_, figure 245) we first note, as we step upon it at _c_, about midway of its length, a small circular depression in the floor of the central room extending slightly beneath the platform, as indicated by the dotted line. It is possible that this niche was a receptacle for important household objects, although it may have been a fireplace. In a corner of the right platform a round cist, partially hewn out of the rock, was found, but its walls (_a_, figure 245) were badly broken down by some former explorer. The floor of this recess lies below that of the platform, while the cist itself (_D_) reminds one of the closed or walled structures, so commonly found in the Verde, attached to the side of the cliff. On the lateral wall of this chamber, at about the height of the head, a row of small holes had been drilled into the solid wall. These holes (_d_, _d_, _d_) are almost too small for the insertion of roof beams, and were probably made for pegs on which to rest a beam for hanging blankets and other textile fabrics when not in use. The roof of the cave was the natural rock, and showed over its whole surface marks of a pecking implement.
