NO. I ARCHITECTURE OF PUEBLO BONITO JUDD 87 



a second and more deliberate Late Bonitian program is only part of 

 the story of architecture at Pueblo Bonito, 



As previously stated, Room 100 occupies a peripheral angle of 

 Old Bonito. It is the only room in the enveloping Late Bonitian 

 2-story row that lacks an external door. Its west wall, despite larger- 

 than-normal component parts, is of second-type masonry and a con- 

 temporary both of that in Room 104, adjoining, and of the northeast 

 wall in Room 92 (pi. 21, upper). Longitudinal ceiling poles in Room 

 100 were covered with split cedar and cedarbark in addition to the 

 willows of the text. "Individual willow strips . . . were used in all 

 the rooms of this outer series" (Pepper, 1920, p. 318). 



These three materials — peeled willows, split cedar, and cedarbark — 

 are seen again in Pepper's figure 137, which illustrates not the ceiling 

 in Room 112 as reported but that of the Hyde Expedition's "old dark 

 room," unnumbered but next east of Room 100. The transverse pole 

 seen in the foreground of figure 137 was a Late Bonitian stringer 

 built into the wall between the "dark room" and that adjoining, a 

 storeroom. Both were roofed by the same lot of ceiling poles, but 

 these were covered in the dark room by layered willows ; in the store- 

 room, by cedar splints and cedarbark. Mindeleff's 1887 photograph 

 (pi. 26, upper) shows those ceiling poles extended through the north 

 wall and about 2 feet of outside masonry above them but all had been 

 stripped away prior to the Society's reconnaissance of 1920 (pi. 3). 



Together with 101, Room 100 filled the broad external angle 

 formed by Old Bonitian Room 107 as it abutted an unnumbered 

 room next on the east (fig. 4). When they built 100, 101, and the 

 partition at the east end of 107, the Late Bonitian architects under- 

 took a little necessary repair work in addition. The floor of 107B, 

 perhaps disrupted by the intruding partition, is described by Pepper 

 (ibid., p. 326) as comprising about twice the usual number of alternat- 

 ing layers of cedarbark and adobe above the original cottonwood 

 beams "of various sizes, shapes, and conditions." 



Since brush of some sort, almost standard in Old Bonitian ceil- 

 ings, is not mentioned in the description, I assume it had been re- 

 placed with the layer of split cedar seen in unpublished Hyde nega- 

 tive No. 371. That same negative also shows, under the cedar splints, 

 a series of small ceiling poles overlying four straight-grained pine 

 logs that alternate with trios of pine poles. Straight-grained pine 

 timbers, peeled willows or split cedar, and cedarbark were favored 

 by Late Bonitian architects and the floor of Old Bonitian 107B was 

 clearly a Late Bonitian repair job.
