MINDELEFF] THE MUMMY CAVE RUIN 115 
under a narrow room or passage, Shown on the plan, and seems to have 
been the floor of that room rather than a roof of a space below. 
Roofing or flooring beams project from the tower on three sides. 
They are all rounded and carefully selected or matched. Those of the 
lower story or first roof are 44 inches in diameter, those of the story 
above about 3 inches, while those of the roof, which oceur in pairs, 
are about 24 inches. They all, except those of the lower story, pro- 
ject about 2 feet from the wall. All the beams are from 18 inches to 2 
feet apart, and the roof is formed of canes or willow sticks less than 
half an inch in diameter laid very neatly in patterns. The work here 
is by far the best in any part of the canyon. The beams of the first 
floor are represented only by the ends which pass through the walls, 
the middle portion being gone. 
The cliff wall forming one side of the rooms in the tower was coated 
with a wash of yellowish clay to correspond with the other sides. It 
shows bare rock at the points where the floors abutted against it. The 
roof of the second story or middle room was 10 inches thick, and the 
marks are on the same level as those of the rooms over the west of the 
tower. There are also beam holes in the third story about 4 feet above 
its floor, but extending only from the cliff out to its opening. 
A singular feature occurs in the tower, which is difficult to explain. 
The upper part of the third-story room was coated in the interior with 
whitewash, which appears to have been carelessly applied. Small 
quantities struck the setback at the floor level and spattered over the 
wall below—that of the second-story room. In one case a considerable 
quantity of the whitewash struck the top of a beam in what would be 
the roof of the second story and scattered over the wall surface below 
it. It is therefore clear that at the time when the whitewash was 
applied, which was either at the time or subsequent to the habitation 
of the rooms, there was no floor to the third-story room nor roof to the 
second story. The stains of whitewash never go below the floor level 
of the second story. 
The house remains in the eastern cove are partly shown in plate 
XLIX, which is from a photograph. The point of view is from the 
ledge in front of the tower. The ruins rest on a ledge in the back of 
the cove formed of débris well compacted and apparently consisting 
partly of sheep dung. The rooms are small, sometimes three deep 
against the back of the cove, and many of them could only have been 
used for storage. The principal structure is the western kiva, with its 
chimney-like attachments. This is described at length on pages 177, 
179, 186, and 187. Adjoining it on the east is another kiva, part of 
whose wall is still two stories high, and clearly shown 1n the illustra- 
tion. Some 50 or 60 feet to the east or southeast there is another cir- 
cular structure, which apparently had no interior bench. The small 
semicircular structure shown on the plan and in the illustration, which 
rests against and is roofed by the rock, is a Navaho burial cist, and
