arrangement much resembled a huge honeycomb. Before consider- 
ing this cist area, however, we will complete the description of the 
other parts of the cave. 
Reference to the plan will show a space along the east and south- 
east walls where no cists were found. Here the face of the trench 
disclosed a surface layer, 6 to 8 inches deep, consisting of sand, 
sheep droppings, and broken stone from the ceiling. Under this 
was an accumulation of rubbish composed of grass, corn husks, and 
bark mixed with sand; it was 3 feet 6 inches deep, and through it, 
at a depth of 3 feet, could be traced an old floor level of closely 
packed rubbish. This same floor level appeared again on the west- 
ern side of the cist area, but here it was mudded over and covered 
a rubbishy stratum of grass, husks, and bark mixed with charcoal 
and ashes. The débris above this floor contained more grass than 
did that below it. 
Beyond the large rocks there is another flat area; this was not com- 
pletely excavated; test holes, however, showed loose rubbish but no 
cists. The foundations of the cliff-house structure at the extreme 
western end of the cave were fully exposed and found to rest on un- 
disturbed hardpan. This was disappointing, as we had hoped to 
recover some stratigraphical evidence at this point. At the western 
front, about the two rocks with the grinding grooves (fig. 28, 7), there 
is a small, level space which was covered, below the surface sand, with 
a thick layer of ashes and charcoal. This section, it may be noted, 
is the only one that receives the sun for any length of time during» 
each day. 
Pottery vessels, presumably deposited by the cliff-dwelling people, 
were found at two places; one, a small black olla, was taken from 
the surface sand near the east wall; the other, a handsome little 
black-and-white jar with a single horizontally placed handle, lay 
close to the back wall and only 8 inches below the surface (fig. 28). 
It was covered by a large sherd and proved to contain an interesting 
and valuable cache of small objects; these are described on pages 
147-151. 
To return to the cists: These were almost all grouped together on 
the gently sloping eastern end of the rear bench and differed very 
little one from another. They were all roughly circular in shape, 
averaged 2 feet 6 inches in diameter, and were about 2 feet 6 inches 
deep. They were made of large unworked sandstone slabs, set on 
edge or on end and generally leaning a little outward (pl. 27, 6). 
The slabs usually met, sometimes overlapped. The cist bottoms were 
often filled with packed adobe, and many of them were lined with 
soft grass or bark. Grass was also frequently used to calk open 
spaces or poor joints between the slabs. In general the tops of the 
cists were found just below the surface layer of sand, and must,
