inches; the third, which was probably only a small storage chamber, 
about 3 feet. At a (fig. 23), just behind room 9, may be seen the 
remains of an old wattle wall deeply sunk in the rubbish; over it 
is a layer of rat dung, and above this again is built a wall which 
extends back to room 6. This upper wall and the walls of room 6 
itself are of masonry much superior to that of the rest of the house. 
The stones are large, well matched, rubbed smooth, and carefully 
coursed, suggesting strongly the masonry of the surface ruins of the 
pass which we investigated later. ‘The wattle wall was built after 
the completion of the tower, room 9, as its edge is modeled up 
against it; the upper wall and room 6, therefore, were constructed 
at a still later date. It is regretted that the unstable condition of 
the high tower forbade more clearing at this interesting spot. The

door of room 6 is much larger than the average. Its height is 2 
feet 7 inches; breadth, 1 foot 5 inches; it has a lintel of wooden 
rods with a slab overlintel set slightly above it (pl. 19, a). 
Room 12 (pl. 19, 6) is in perfect preservation; its back wall and 
roof are provided by the cave. The door differs slightly from the 
normal in that its wooden lintel, made of three cedar slats, sets 
directly against the stone slab lintel instead of half an inch to an inch 
below it. Built into the walls are several stones bearing incised de- 
signs (pl. 19, 6, lower left-hand corner). That the decorations were 
cut on the stones before they were introduced into the masonry is 
shown by the fact that the adobe mortar runs over the designs in sev- 
eral instances. One block pictured in plate 20 is even more conclu- 
sive; it was broken in two and the halves were built into different
