dwellings. 
The house contains two kivas and nine or ten small cell-like rooms 
of irregular shape (fig. 83). The two kivas were built side by side 
in the lower front slope of the cave, and were probably only semi- 
subterranean, as the cave deposit is relatively shallow. Their rear 
or eastern sides were sunk into the earth, while the sides toward the 
mouth of the cave doubtless stood free. If they had been made en-

lay enough underground to bring the roofs to a level with the floor 
of the cave behind (fig. 4). 
Kiva I (fig. 5), the eastern and larger of the two, is a plain cir- 
cular room without niches; diameter, 14 feet. The front or south- 
western wall has fallen away; the débris seems to show that large flat 
slabs of stone had once been set vertically in it, and it was further
