Toward the south margin lay burned bones here and there, too 
fragmentary to identify, except a short piece of a human femur 
converted into charcoal. 
In the middle of the structure was a vault, a considerable portion 
of which was in a chaotic state as the result of the efforts of the 
earlier diggers. Possibly stone graves were made in portions of this 
mound as inno. 11. However this may be, there was good evidence 
that a minor or secondary vault had been constructed on top of the 
earth filling the principal one. So far as could be determined this 
upper vault was 5 feet 3 inches long inside and 9 feet long outside; 
it was built on the same lines as the lower or older one. Close to 
its northwest wall, inside, were several fragments of deer bones, 
including the leg and the skull. At the bottom, a foot east of the 
center, was an adult skull, quite thick, but so crushed that its posi- 
tion could not be determined, though it seemed to face northwest, 
with the vertex toward the northeast. Close to it were beads made 
of small marine shells, and teeth of a young child. Two feet south- 
west of the skull were fragments of the lower portion of a pot which 
had been placed there upright. 
When the main walls were laid bare in their entire circuit, there 
was exposed a structure approximately quadrilateral, with rounded 
corners. The diameters were 17 feet 8 inches from northeast to 
southwest, and 13 feet 6 inches from southeast to northwest. Along 
the outside, between the points where the boundary lines would 
intersect if projected, the measures were: From south to east corner, 
18 feet; from east to north corner, 13 feet; from north to west corner, 
15 feet 6 inches; from west to south corner, 11 feet 8 inches. The 
outer boundaries of stones fell within these intersections as follows: 
East corner, 3 feet; north corner, 16 inches; west corner, 16 inches; 
south corner, 15 inches. The height from the original surface of the 
ground to the highest undisturbed stone in the upper vault was 5 
feet 6 inches; to the average level of the top of the slabs of the 
upper vault, 5 feet; to the top of the original vault, 3 feet 8 inches. 
From a point near the north corner to the east corner, thence for 7 
feet 6 inches toward the south corner, there was apparently a break in 
the outer part of the wall, a single row of rocks at the top resting on 
earth. When this earth was thrown out, the rocks fell. It was soon 
found, however, that this earth filled the same office as the outer 
stones at other points, its purpose being merely to support or brace 
the main wall, and that the outer row of stones along its top had 
been placed there as the finishing layer. 
Near the surface of the earth filling the lower vault was a charred 
log, apparently white walnut, extending from the east corner, past 
o) 
the center, almost to the opposite wall; this had been burned here,
