was razed and replaced by the Late Bonitians. How much farther it 

 extended I do not know, but there is a hint of it in the subfloor walls 

 and storage bins of Room 62 and Pepper's figure 107 (p. 260) 

 shows an arc of plastered first-type masonry underlying the south 

 side of Room 76 with an intrusive Late Bonitian slab-lined fireplace 

 above. 



Similarly, crossed walls under the floor of Room 66 were "evi- 

 dently part of the old building" (ibid., p. 248). I cannot follow 

 Pepper's notes on adjoining Room 65, but his figure 103 shows what 

 appears to be Old Bonitian stonework under the northeast corner — 

 stonework I have hesitated to chart on our figure 3. 



Again, in Room 64 "a series of walls was found under the floor" 

 (ibid., p. 237), and one of them, seen in unpublished negative No. 225 

 deep below the much-plastered and much-smoked Late Bonitian 

 masonry on either side, is a cross wall that is more likely Old Bonitian 

 than otherwise. Also, what I judge to be portions of other old house 

 walls appear, in Pepper's unpublished negative No. 253, below the 

 east half of Kiva 75 and under both ends of its west-side vault. 



Three sections of indubitable Old Bonitian stonework, their asso- 

 ciated floor at depth of 8 feet 2 inches, were exposed by our trenches 

 at the west end of Room 314. Opposite, in the northeast corner, are 

 more old walls sooted and plastered, some of which surely extend 

 subfloor into Room 74, at the southwest corner of Late Bonitian 

 Kiva 75. Finally, 7 feet 2 inches beneath the floor of Room 290 we 

 came upon a well-marked pavement with associated Old Bonitian 

 stonework that was 11 inches thick, unplastered on the exterior but 

 both plastered and sooted inside. 



These several observations, together with Rooms 315 and 316, 

 lend substance to my belief that the right wing of Old Bonito ex- 

 tended at least this far to the east before it was razed to provide 

 space for the Late Bonitian walls now standing. 



Rooms 315 and 316 are portions of Old Bonitian structures that 

 were reduced in floor area and otherwise altered when Late Bonitian 

 architects built in a substitute northeast side, 8;^ feet high, partially 

 to serve as foundation for a third-type wall enclosing Rooms 290, 

 291, 74, and 314 and overhanging the north arc of Kiva L. In both 

 315 and 316 that built-in substitute consists largely of dressed blocks 

 of friable sandstone and abuts plastered Old Bonitian stonework at 

 either end. Both rooms had been roofed at a height of 7 feet, but 

 the Room 315 ceiling rested upon two 8-inch longitudinal beams while 

 that in 316 was supported by four similar beams placed transversely.
