MiNDELEPT] OPENINGS IN OUTER WALLS. 317 



Tlie large fallen block near the southwesteru corner of the room, which 

 undoubtedly slipped down from above, shows a finished surface at the 

 ground level inside, but above it no trace of an opening can be seen, 

 l)ossib]y because the ends of the walls above are much eroded. 



The uijper opening in the eastern wall of the eastern room was appar- 

 ently capped with a single lintel composed of five sticks 4 to 6 inches 

 in diameter laid level on the top of a course of masonry. The bottom 

 of the opening is filled either with washed-down material or with the 

 remains of a block such as that previously described. This opening is 

 the most irregular one in the building, the top being nearly 4 inches nar- 

 rower than the bottom, but the northern side of the opening is vertical, 

 the southern side only being inclined inward. The opening was 4 feet 

 11 inches high audi foot 8i inches wide at the bottom. The opening 

 immediately below that described, which was the ground floor entrance 

 from the east, is so much broken out that no evidence remains of its 

 size and character. There appears to have been only one row of lintel 

 poles. 



The eastern opening in the southern wall of the northern room is well 

 preserved, the lintels having been torn out by relic hunters without 

 much destruction of the surrounding masonry. It was neatly finished, 

 and its bottom was probably a little above the first roof level. The 

 edges of the openings were made straight with flat sticks, either used 

 as implements or incorporated into the structure, and forming almost 

 perfectly straight edges. Marks of the same method of construction 

 or finish are apparent in all the other ojienings, but the remains are 

 not so well preserved as in this instance. Possibly the immediate lin- 

 tels of openings were formed of thin flat sticks, as the lintel ijoles are 

 often some inches above the top of the opening. In this opening the 

 supporting lintel was formed of a number of poles 2 to 4 inches in 

 diameter, irregularly placed, sometimes two or three in vertical series 

 with very little filling between them. This construction has been char- 

 acterized as a Norman arch. The opening was originally 1 foot 11 

 inches at the top and 4 feet 6 inches high. The bottom is 1^ inches 

 wider than the top. 



The ui)per oi^ening in the western end of the southern wall is much 

 like that just described. A small fragment of masonry above the lin- 

 tel remains, and this is within a quarter of an inch of the top of the 

 opening. Above the opening there was a series of rough lintel poles, 

 3 to 5 inches in diameter, arranged in three tiers with 4 to inches of 

 filling between them. Prints of these sticks are left in the wall and 

 show that some of them were quite crooked. Probably they were of 

 mesquite, obtained from the immediate vicinity. The edges of the 

 openings were finished with flat sticks, like those described, and its 

 bottom was 6 inches to a foot above the floor. The height of the open- 

 ing was 4 feet 3 inches and its width at the top 2 feet, at the bottom 2 

 feet 1:^ inches.
