but in either case its construction followed demolition of a second- 

 type kiva whose floor lies 8 feet 11 inches below that of third-type 

 Kiva U. To judge from the arc we exposed, the wall of this earlier 

 chamber, 21 inches thick, was razed 4 or 5 feet above its encircling 

 bench. This latter, likewise partially razed, had been 30 inches high 

 but my notes do not record its width. We guessed floor diameter at 

 about 23 feet. 



Thus the initial building activities of the Late Bonitians included 

 not only Rooms 115, 116, and those adjoining on the south but also 

 the original of Room 25 and north therefrom. Room 25 appears to 

 have been the approximate turning point beyond which Late Boni- 

 tian architects did not venture in their first constructional program. 

 The partially razed second-type kiva 9 feet under Kiva U was part 

 of that initial program and salvable materials from it and from the 

 under-floor walls in Rooms 25, 106, and 336 might account for the 

 mixed masonry of the wall separating Kivas U and W. 



Because the lower 9 feet 2 inches of that wall was not plastered 

 externally it could, conceivably, have been built to conceal the par- 

 tially razed remains of the older, underlying kiva, but its plastered 

 upper half, above the 9-foot-2-inch level, seemingly was intended to 

 screen two or more second-story rooms. In the portion we examined, 

 two former doors, both subsequently blocked, appear 16 inches above 

 the line of plastering or 10^ feet above the basal work surface. 



The first of these two doors, 24 inches wide by 46 inches high, had 

 been carefully sealed and thereafter was abutted by the front wall of 

 Room 336 when this latter and those next on the south formed the 

 west boundary of the Court. The second-story rooms once entered 

 through those doors had in their turn been demolished to provide 

 space for Kiva U, 13 feet 10 inches in diameter, but the wall itself 

 was left standing. 



There is much hereabout not clarified by our researches. Good 

 second-type masonry underlies the east side of Rooms 331 and 332, 

 abutting the thickly plastered, chip-studded exterior of Old Bonitian 

 Room 330, but cramped quarters discouraged deep digging. The wall 

 separating these two small rooms was a partition only, built upon 

 their floors, but that at the west, part of the Kiva U enclosure, re- 

 tains a strong flavor of early Late Bonitian architecture. If not part 

 of the original building program, these several walls were erected 

 with stones salvaged from razed second-type rooms. A blocked and 

 plastered door, 22 inches wide, at the south side of Room 332 and 

 5 feet above its floor does not, in my opinion, represent a second story
