IV. THE THIRD-TYPE ADDITION OF 

 THE LATE BONITIANS 



The Pueblo III coresidents of Pueblo Bonito began their second 

 and more ambitious constructional program at the blocked west door 

 of Room 115. Here, midway in the row of 2-story houses they had 

 previously built to enclose crescentic Old Bonito, the Late Bonitians 

 introduced a new variety of stonework, splicing it into the second- 

 type masonry of Room 115 and extending it southward in a wide- 

 sweeping curve to Room 337, at the extreme southwest corner of 

 the pueblo (fig, 5). 



That new variety consists of larger building stones separated by 

 bands of inch-thick tablets of thin-bedded, laminate sandstone. No- 

 where about the village are the differences between second- and 

 third-type masonry more clearly portrayed than here at the blocked 

 west door of Room 115 (pi. Z7 , upper). The builders tore out the 

 south jamb of that blocked door and tied in their new stonework at 

 sill level, 3 feet 9 inches above the second-type foundation. Ten feet 

 to the south the newer stonework overhangs the older by 5 inches. 



In its southward extension the substituted wall conceals a blocked 

 west door in Room 116 and curves outside the next 3 rooms, likewise 

 of second-type masonry but unnumbered and unexcavated. Blocked 

 west doors in two of these are to be seen in Room 117, their decayed 

 lintels 21 inches above its adobe floor. Triangular Room 117, unnum- 

 bered on Hyde's plan of Pueblo Bonito {in Pepper, 1920, fig. 155), 

 is readily identified by unpublished Hyde prints No. 550 and 552. 



Late Bonitian architects really got under way with Room 117 but 

 first they changed their minds a couple times. Their initial plan 

 was to add an external block of six contiguous rooms joined to the 

 older second-type masonry (fig. 5). They laid the foundations, 

 prepared for an east-wall tie-in, and actually started building. Then 

 they abandoned this first plan in favor of one whose outer west wall 

 abutted the southwest corner of Room 116, extending thence south- 

 ward on a foundation 29 inches wide by 34 inches high and now 

 underlying Rooms 117, 118, and 119. 



Then this second plan was discarded. The builders abandoned 

 their 29-inch foundation and built a new one 3 feet outside, this 

 time dovetailing its masonry into the blocked door of second-type 

 Room 115, and bringing it down past 116 to form the present west
