52 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 77 



A series of steps leads up the cliff from the northeast corner of 

 room 75 to the retaining wall opposite the northwest corner of room. 

 78 and was undoubtedly used before houses were built in this quar- 

 ter. Above rooms 83-85 the cliff appears too precipitous for dwell- 

 ing sites. 



Lack of time precluded even partial restoration of the demolished 

 buildings we have numbered 131-135, But we renewed the old step 

 series from the northeast corner of room 75 down to the platform 

 back of room 82, thus facilitating access to court 83 and its near-by- 

 storerooms. 



Retaining wall. Rooms 78-81 and 124r-127 stand on a level ledge- 

 at the upper east end of the cave. Erected upon a 2-inch groove,, 

 pecked on the outer edge of this terrace just where the cave floor 

 drops abruptly down to rooms 82-85, is what we have called " the- 

 retaining wall." It is the counterpart of that which inclosed court, 

 10 and continued southward to form the walk leading to room 3. 



The east retaining wall widened the natural terrace and thus; 

 formed in front of the dwellings a walk that varies somewhat in 

 width as it extends from room 81 northward to room 124. Opposite 

 the south corner of room 81 this terrace walk is 2 feet 6 inches. 

 (0,76 m,) wide; at the south corner of room 80 it is 4 feet 3 inches 

 (1.3 m.) wide; at the south corner of room 78, 4 feet (1.2 m,) ; at 

 the west corner of room 78, 3 feet 9 inches (1.14 m.). Three slab 

 steps, totaling 15 inches (0.38 m.) in height, connect the upper ter- 

 race level fronting rooms 79-81 with the lower level northwest of 

 room 78. 



We repaired and recapped the retaining wall throughout its 

 greater length; rebuilt a missing segment above rooms 132 and 134 

 after widening and deepening its seating groove ; omitted restoration 

 of the extreme ends. (Pis. 19 and 20.) As noted under the descrip- 

 tion of individual rooms, certain minor repairs were also made on 

 the houses hereabout. 



Gallery xoall. — In the high, upper portion of the cave, on the very 

 edge of the cliff and about 25 feet (7.62 m.) above room 59, is a 

 long straight wall approximately 4 feet (1.2 m.) high. Viewed from 

 below, this wall appears to stand alone, but there is a bare possibility 

 that other walls lie buried in the loose shale which has accumulated 

 on the slope behind the wall. About 2 feet (0.60 m.) above the front 

 base of the masonry 11 poles protrude to suggest a probable floor 

 level behind the wall. 



x4.ccess to the gallery was formerly gained by means of the long 

 pine pole still standing at the north end of court 10. Only one who 

 has shinned up this splintery pine and felt it tip threateningly out- 

 ward from the sheer cliff can fully appreciate our lack of knowledge- 

 concerning the upper gallery and the structures, if any, it shelters.
