152 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I47 



previously demolished several third-type kivas to obtain building 

 material. 



Additional sections of fourth-type masonry 3-9 inches high survive 

 at Stations 3, 4, 6, and 7, at various places identified by the letter 

 "x" on our chart of the Complex (fig. 11) including the masonry 

 box outside Room 186, an 18-inch- wide east- west wall remnant a 

 foot and a half under the floors of Rooms 256 and 257, a subfloor 

 foundation similarly oriented in Room 185, and a north-south wall 

 section paralleling the west side of 244 at a distance of 30 inches. 



The exposure bared at Station 6 is especially puzzling in that a 

 facing of banded fourth-type masonry continuing north from 

 Station 4 is here screened by an over-wall of friable sandstone and 

 mud that looks somewhat finished externally but is, nevertheless, 

 foundation-like throughout. At its north end this close-fitting over- 

 wall is buried under 3 feet 9 inches of blown sand in which we noted 

 successive gravel lenses and a scattering of clay pellets. 



Station 7 is unique in that here 8 inches of fourth-type masonry 

 remain upon a 26-inch-high foundation that consists of dressed 

 friable sandstone chinked after the fashion of second-type stone- 

 work, its base 5 feet 4 inches below the present surface. On the east 

 side of this composite, its bottom at a depth of 6| feet, is a 3-foot pile 

 of constructional waste — the most likely indication of deliberate wall- 

 razing we noted throughout the whole Complex. 



This single example of second- type masonry — there may well be 

 others we did not come upon — and three known kivas constructed in 

 what I recorded as third-type provide further evidence that the 

 Late Bonitians did not hesitate to tear down still useful structures 

 when building materials were required for others in prospect. That 

 salvaged materials at hand sometimes prompted a workman to do a bit 

 of wall-building on his own seems only natural — a brief respite from 

 the tedium of shaping foundations from mud and broken rock. 



Figure 11 shows only that portion of the Northeast Foundation 

 Complex we actually uncovered. We have no knowledge of what still 

 lies buried. A cross section (D-46) between "A," on a main east- 

 west foundation outside Room 185, and a like symbol near Station 2 

 at the east end of our trenching operations does not, in my opinion, 

 contribute enough information to justify its reproduction herein. It 

 remains on file at the U. S. National Museum together with all other 

 diagrams and field notes of the Pueblo Bonito Expeditions. I might 

 add, however, that 12 deep silt layers shown on that cross section lie 

 at practically the same level, no more than 8 inches apart vertically.
