Feature No. SO. — The post-mold pattern outlining the fourth struc- 

 ture was 13 inches above the hardpan. This pattern, shown in figure 

 39, indicated a building 37.4 feet long by 26 feet wide. The height 

 of the floor of this structure above that of the tertiary structure, 

 Feature No. 39, varied from 2 inches to 12 inches. Along the borders 

 of the structure the difference was least. It was greatest in the cen- 

 ter, and on the south end it ranged from 11 inches to 13 inches. 

 Plate 54, a, shows the post-mold patterns of the third and fourth 

 structures. The top of the rim of the fire pit, Feature No. 35, is on 

 the level of the fifth floor. The earth has been cut down to the 

 fourth-floor level all around it. Note the 6-inch rule set on end. 

 On the fourth floor the surface in the center of the area was basin- 

 shaped on three sides — the north, east, and west. This caused the 

 great height of the precedent floor above this — the fourth floor — at 

 the center, and brought the post molds of these three structures to 

 almost the same level on the north, east, and west sides. Plate 54, a, 

 brings this relationship out very clearly. 



Feature No. SI. — Near stake 8.5 there was a baked-clay fire pit 15 

 inches in diameter and 6 inches deep, filled with midden at top and 

 gray ash at bottom. This feature occurred in the center of the sixth 

 structure, Feature No. 29, and was on the floor level of that structure. 



Feature No. SS. — At the northern end of the seventh structure 

 horizontal post molds were found just inside the pattern of vertical 

 molds 15 inches above the hardpan. These molds were well-defined 

 hollows partially filled with decayed wood. Their maximum length 

 was 8 feet and their maximum diameter 6 inches. The molds are 

 shown in plate 55, a. It is believed that these molds were made by 

 roof logs which fell to the town-house floor when the structure was 

 destroyed to make room for the erection of a new house above this 

 floor level. 



Feature No. SJ,. — This feature indicates the relation of two clay 

 platforms found on the northern end of the primary and secondary 

 floors. These platforms were easily defined, since they were made 

 of clay and covered with midden. They were placed one just inside 

 the primary structure wall and the other just inside the secondary 

 structure wall. 



Feature No. SS. — At stake 7.6 a clay fire pit was found 22 inches 

 in diameter and 8 inches deep, filled with gray ash. This pit was 

 on the floor of the fourth structure. 



Feature No. S6. — Lying in the square 3.7-4.6, and precedent to the 

 seventh structure in the mound, was a post-mold pattern in the orig- 

 inal hardpan. This pattern shows an approximately rectangular 

 structure 14.8 feet long and 13.8 feet wide. 



Feature No. 37. — About stake 5.5 on the hardpan surface a group 

 of some nine large stones were found standing on edge and irregu-
