with a maximum breadth of 21 feet, reaching nearly to the east margin 
of the mound. When cleared off, these rocks were found to lie 
entirely to the west of the center, there being but few in the eastern 
half, and those superficial. At the top the rocks were in the form of a 
rough wall of irregular height, inclosing a space 94 feet southeast 
by 7 feet northeast. The northeast wall was straight for 8 feet 9 
inches; the northwest wall for 4 feet 10 inches; the southeast wall for 
4 feet 9 inches; the two corners of these three walls were somewhat 
rounded. The southwest wall, 10 feet long, had a tolerably regu- 
lar outward curve. The above dimensions are all inside measure- 
ments; the corresponding outside measurements were: Northeast 
wall, 11 feet 6 inches; northwest wall, 6 feet 6 inches; southeast wall, 
7 feet 6 inches; southwest wall, 14 feet. 
The general appearance of this vault, on the outside, before the 
supporting earth was removed, 
is well shown in plate 5, a. 
In clearing out the vault, 
fragments of human _ bones 
were found scattered through 
the earth from top to bottom. 
There were parts of 12 skulls, 
and fragments of 5 pots, the 
latter entire when placed here 
but now much broken by pres- 
sure, besides numerous pot- 
sherds.. Two of the pots, one 
upright (fig. 6), one inverted, 
were near one skull. Beside 
one of the pots were part of a 
human ulna and three leg 
bones of a panther. The vault 
was 2 feet 9 inches deep from the top of the highest stone to the 
bottom of the lowest stone. In the southwest wall was a space 24 
inches wide, filled with earth, in which no stones appeared except 
three slabs along the outside, set up against the earth. This was 
the doorway or entrance to the vault, the stones in the wall at each 
side of it being regularly laid up (pl. 5, 0, ¢). 
Along the bottom, the inside of the vault was nearly rectangular, 
the walls being about as straight as they could be made with un- 
dressed stones. The length on the bottom from northwest to south- 
east was 8 feet 7 inches; the breadth 3 feet 11 inches. The northeast 
wall was composed mainly of seven slabs, inclined slightly from the 
perpendicular to rest against the supporting earth outside; the 
largest slab was 36 by 19 inches; the longest, 41 by 16 inches. The
