Separating this from the superstructure, as will be seen by reference 
to Fig. 4, was a thin sagging streak of burnt clay. Tere and there

upon its surface scant traces of black wood ashes were seen, while a 
small quantity of white bone ashes lay scattered upon its western 
border. This burnt streak overlaid a thin sand seam, below which it 
seems it could not penetrate. The post molds of the superstructure 
consisted of a double row, the outer line being uniformly directly over 
the lower series in a vertical line, and separated from the latter entirely 
around the cirele by a solid line of gravel. The two rows of the upper 
structure averaged 18 inches apart. Both might have penetrated orig- 
inally beyond the surface of the mound, since they were discovered 
between 14 and 2 feet beneath the surface, which had been considera- 
bly plowed. Horizontal timber molds, a little smaller in diameter, 
filled in places with charcoal, could be distinetly seen lying against the 
side of each line of posts at the points shown in the figure. These 
appear to have been cross-beams or stays used for bracing purposes. 
In the eastern trench a gap 3 feet and 2 inches wide was noticed by 
the absence of post molds in both upper and lower series. 
Within the area inclosed by these posts, all the skeletons were 
interred. These lay at different depths and in different positions, the 
favorite or predominant one, at jeast in the upper portion, being 
just inside and alongside of the inner circle of palings. The skeletons 
unearthed were all in a remarkably good state of preservation. None 
of them could have been intrusively buried, for the stratification above 
them was not disturbed. All excepting Nos. 15, 16, and 17, lay upon 
one or another of the thin seams of sand. All except No. 6 lay stretched 
out at full length. The latter lay partly upon the side with knees
