ing else (pi. 64, upper). It is oblong, and east and west are broad 

 recesses surprisingly alike in size and appearance. Both are 21 inches 

 deep and 8 feet 2 inches wide in front ; both are paved with bare 

 sandstone slabs. There is an oval, slab-lined fireplace at midfloor 

 and from the south side of it an under-floor ventilator duct extends 

 to and beneath the middle of the south wall. We did not locate the 

 opposite end. 



Against the north side of 2-D and built upon its floor is a masonry- 

 walled shaft, 10 by 13 inches inside, floored with part of a 2-inch- 

 thick Old Bonitian metate, and having a 12 x 19-inch opening in 

 front. In the kiva wall just outside this feature and 23 inches above 

 the floor, is a small T-shaped niche, 8 inches high, plastered inside 

 and dark from smoke. 



Although indefinite as to type the masonry of 2-D is composed of 

 both dressed friable sandstone and laminate sandstone and is prob- 

 ably later in Pueblo Bonito history than appearance suggests. Its 

 walls were sooted before the latest coat of plaster was applied. 

 Although its floor lies about 7 feet below West Court surface the 

 enclosing stonework had been razed to an average height of 4^ feet, 

 the roofing timbers salvaged, and the empty room finally used as a 

 communal dump. 



Kiva J is one of standard Chaco type, but 3 feet 4 inches under- 

 neath its floor is a D-shaped predecessor that proved much more 

 interesting (pi. 65, lower). This under-floor example was built from 

 the inside and repeatedly plastered. It had no bench, no south recess, 

 and no pilasters. Its central fireplace, 26 by 29 inches and 21 deep, 

 had rounded corners and a low, wide-spreading adobe rim. 



Thirteen inches south of this unusual fireplace is the unusual out- 

 let for an unusual ventilator duct. That outlet, 18 inches on the 

 west, 29 inches on the north, and 16 inches on the south, opens at its 

 southeast corner into a subfloor duct, 32 inches deep, that narrows 

 as it continues southeast, under the wall and 16 inches beyond, to an 

 air intake that rises through the Kiva J floor. As noted on the ac- 

 companying plan (fig. 20), that intake is not aligned with its channel 

 but lies a little to one side. There were no other features to this 

 queer, D-shaped sub-floor kiva. The rude wall that divides it was 

 a later introduction and without recognizable purpose. 



Construction of the Kiva J ventilating system and west vault 

 demolished the southwest quarter of the older room but did not 

 disturb the arc of a still older, second-type-masonry kiva, subfloor 

 in Rooms 165 and 273, Like Kiva H, Kiva J had been stripped of its
