88 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I47 



Room 107 was abutted by Late Bonitian storeroom 101 and the 

 latter was connected with its contemporary, 93, by an open door and 

 at least one ventilator. Southward from 93 the remaining houses in 

 the encompassing Late Bonitian row had largely succumbed to the 

 elements prior to 1877 (Jackson, 1878, p. 441). The outside wall of 

 each room was 2 or 3 inches thicker than its opposite and these inner 

 walls were built as close as possible to the sloping exterior of the 

 older building leaving a V-shaped space to be filled with sand and 

 constructional waste. Protected by such waste, the exterior of Old 

 Bonitian Room 102 retained a superb example of the studwork, or 

 "mosaic," that I believe once covered the outside of Old Bonito, or 

 most of it (pi. 11, right). 



The Hyde Expedition concluded its examination of this Late 

 Bonitian west-side row of 2-story houses with excavation of Rooms 

 114, 115, and 116. Like those previously cleared, these three were 

 built of relatively large friable sandstone blocks, rubbed smooth 

 and chinked between with laminate chips — the very acme of second- 

 type masonry (pi. 10, 2). This use of thin laminate sandstone as a 

 chinking medium, so dififerent from the mosaic-work of the Old 

 Bonitians, really introduced tabular sandstone as a local building 

 material. Thereafter, as the Late Bonitians pursued their successive 

 expansion plans they utilized increasingly thicker blocks of the lami- 

 nate variety and came ultimately to use it altogether. 



Each room in the outer 2-story row was provided with 3 doors, 

 each wider at the sill and each with 7-9 clean, pine lintel poles that 

 might extend several feet beyond the jambs, perhaps to the side 

 walls. In each instance the outside door was closed with masonry 

 matching that of the wall itself ; in each instance second-story doors 

 occupied the same relative position as those of the first story. Appar- 

 ently, there was no ground-floor fireplace in any of these 2-story 

 houses; no interior plaster; no smoke-blackened walls; no evidence 

 of occupancy. Together they formed a single row hiding the convex 

 exterior of crescentic Old Bonito. 



Late Bonitian Room 114 had a ceiling height of 10 feet 4 inches; 

 at ceiling level its east wall stood 16 inches from the outside of Old 

 Bonitian Room 317, next on the east. This old exterior, thickly plas- 

 tered, doorless, and slanted inward like others of its kind, rose from 

 a 17-inch-high foundation based on clean sand 5 feet 10 inches below 

 floor level in Room 114. Thus the Late Bonitians began their en- 

 veloping row of 2-story houses almost at first-story ceiling level of 

 the old village. If my calculations are correct, the floor of Old 

 Bonitian Room 317 is about 4^ feet lower than that of Room 114.
