NO. I ARCHITECTURE OF PUEBLO BONITO JUDD 29 



above the floor ; those of the second-story are usually larger than first- 

 story ventilators. Of our total, 122, or 67 percent, had been wholly or 

 partially closed with masonry, usually to leave a shallow inside recess. 



Since ventilators presumably were intended to provide cross ven- 

 tilation, the blocking of them, whether partial or complete, would 

 seem to indicate a desire for simple physical comfort. Winters are 

 cold in Chaco Canyon and reduced or closed ventilators would lessen 

 winter drafts. I place no faith in theories that the blocking was a 

 defensive measure. Nine ventilators in the west walls of two Old 

 Bonitian storerooms, 320 and 217B, were sealed with stonework when 

 the Late Bonitians erected their 2-story row of second-type rooms 

 adjoining. 



Storage shelves and clothes racks. — Single poles, 2 to 3 inches in 

 diameter, across the width of a room and 5 to 5^ feet above its 

 floor presumably served for hanging blankets and similar materials 

 as such poles still do in Pueblo homes. At least five second-type Late 

 Bonitian rooms (200, 203, 204, 209, 299) had been equipped with one 

 or two single poles of this sort. Of 16 two-pole racks noted, 4 occur 

 in Old Bonitian rooms (298B, 307-1, 315, 320) and obviously were 

 introduced after construction. 



Pepper (1920, p. 223) describes a 3-foot-high shelf at the west 

 end of Room 62 — three 4-inch-diameter logs, 2-inch poles above them, 

 and a reed mat lashed on top by means of cedar splints and yucca 

 thongs — and implies a second shelf at the east end. With little more 

 than standing room between, two such shelves would measurably in- 

 crease the storage capacity of a given room. Apparently such storage 

 shelves were more frequent in the upper rooms of Pueblo Bonito. 



Unpublished Mindeleff photographs show seven, possibly eight, 

 close-lying pole seatings in the remaining north third of the west wall 

 of Room 179C a couple inches below a half -blocked ventilator, but 

 no provision had been made for a similar shelf in Room 180C, ad- 

 joining, where two west ventilators remain open. Seven pole seat- 

 ings at lintel level of the southwest door in Room 185B and immedi- 

 ately below a ventilator were not matched by like seatings in the 

 north half. 



Seven-pole shelves may have been standard in upper storage rooms. 

 Mindeleff photographed such a series in the west half of the north 

 wall, Room 187C, at sill level of the third-story west door — a series 

 that we carefully preserved during 1923 repairs (pi. 9, left) but 

 which subsequently was lost when the Braced-up Cliff collapsed.
