that if extended they would meet over the center of the room at 
about 6 feet above the floor, forming a flattish conical roof. Over the 
poles there had been a layer of reeds and grass, parts of which, com- 
pletely oxidized, were found adhering to what was left of the rafters. 
The middle of the roof was probably slightly above the old ground 
ievel, as indicated in figure 18. A hatchway must have been used for 
entrance. At first sight this room had all the appearance of a kiva, 
but excavation showed that there was no ventilating apparatus, no 
fire pit, sipapu, or any of those features which seem essential to cliff- 
dwelling kivas.

Fig. 18.—Round room in Ruin 5. 
The logs and the three posts shown in figure 15 form part of a 
piece of terracing work, belonging probably to the earher occupancy. 
The culture deposit behind the posts and nearly up to the three 
back rooms was the deepest in the cave, but was too moist except 
at the top to contain anything but objects of bone, stone, and pot- 
tery. The lower levels held, as elsewhere in the cave, the crude 
black ware and the unfamiliar style of black-and-white ware; it was 
also noticed that there were many more chips of stone and whole 
and broken flaked implements in these lower levels than in the upper 
rubbish. The percentage of bone implements was also greater; in 
particular there were found two bone implements with perforated 
butts (see pl. 64, ec, 2) ; another was taken from the floor of the round 
room.
