of these structures were burned ; and the nearly complete absence of 

 horizontal molds at all levels, except this one, seems to indicate that 

 the earlier buildings were removed from the site each time before a 

 new building was erected. Had the buildings been allowed to col- 

 lapse and fall in disarray, the wall and roof logs would surely have 

 left horizontal molds at each level of a structure floor, as seems to 

 have occurred in this instance. 



Feature No. W. — This feature shows the definite relationship which 

 existed between the seventh and eighth structure in the center of this 

 mound. As the mound was topped by removal of horizontal slices, 

 the post-mold patterns of two structures were apparent. These 

 proved to be the seventh and eighth structures built on this site. The 

 floor of the eighth structure was 4 feet 4 inches above the hardpan 

 and was so near the surface of the sides of the mound that it had 

 been much damaged by the plow. The seventh structure floor was 

 3 feet 3 inches above the hardpan and was well preserved. The floor 

 of Structure No. 8 was about 13 inches above that of Structure No. 7, 

 and since this was about the depth below the floor of the post molds 

 of Structure No. 8, their bottom was at about the same level as the 

 top of the molds of Structure No. 7. This relationship is shown in 

 plate 50, a. The tops of these molds represent the floor level in each 

 case. Plate 51 shows the method of topping the mound and shows 

 the seventh and eighth structures blocked out. The post molds of 

 the eighth structure are visible along the higher of the two blocks. 

 The post molds forming this structure indicate that the posts were 

 from 7 to 10 inches in diameter, which is much larger than those 

 previously reported from the other sites in the Norris Basin. 



Feature No. 21. — Near stake 6.6 and from 5 feet to 5 feet 3 inches 

 above the hardpan was an ash layer above the seventh floor and it 

 was covered by a line of dark mold between this ash and the material 

 above. 



Feature No. 22. — About stake 8.8 post molds in the clay hardpan 

 outlined a structure of four equal sides, each side being 12 feet 8 

 inches. The corners were not square. The pattern of this structure 

 is shown in plate 49, b. 



Feature No. 23. — This feature was the pattern of post molds out- 

 lining two sides of the eighth structure. This pattern was 4.4 feet 

 above the hardpan and seemed to indicate a structure 21 feet by 24 

 feet. Only the south and east walls of the structure were indicated. 

 The north and west sides of this post-mold pattern, which were not 

 found, may have been plowed away, because on those sides they 

 would have been very near the surface. Besides Feature No. 17, 

 previously described, there was a burned area on the same level 

 which was thought to mark a portion of the floor of this structure.
