made of slabs, terminating 14 inches from each end; in the southwest 
corner was a space 1 by 3 feet where no stones had been placed. 
No reason was apparent for the existence of this pavement. There 
was considerable charcoal mixed with the earth which filled the 
vault, but no trace of bones or of worked objects appeared. 
The walls, partially demolished by former investigators, were 
held in place by rocks and earth piled against the outside surface. 
The interior of the portion of the walls remaining in place on the north 
side and at the west end is shown in figure 2. It will be observed 
from this figure that two parallel walls were first built, the other two 
walls being so constructed subsequently that the ends of each interior 
wall abutted squarely against the faces of the others.

THE BrrxteE Mounp (4) 
Two miles east of Gasconade, on a high point on Mr. Robert Birkle’s 
land, stood a mound having a base measure of 40 feet east and west, 
50 feet north and south, and an elevation of 5 feet. Originally the 
base was circular, the alteration in form being due to long cultivation. 
The central portion was cleared out by a trench, or pit, 20 by 24 
feet. A slab of chert, weighing about fifty pounds, from a stratified 
rock, lay on the bottom at the center, evidently having been placed 
there intentionally, and a few sandstone and limestone blocks lay 
scattered about in the earth.
