Mound No. 3, " Mound City " 
Mound No. 3 is egg-shaped in form, and measures 140 feet 
in length, by fifty and sixty feet respectively at its greater and 
smaller ends ; it is eleven feet in height. Two sand strata 
were observed in this mound. Although the altar" was 
not fully exposed, yet enough was uncovered to ascertain its 
character and extent. Forty-five feet of its length was 
exposed, and, in one place, its entire width, which was eight 
feet across the top, by fifteen at the base. The length of the 
altar could not have been much less than sixty feet. The 
relics were found in the inner basin. The altar was burnt 
to the depth of twenty-two inches. Upon careful examination 
it was found that three altars had been built, one upon another, 
as if one had been used for a time, until, from defect, or some 
other cause, it was abandoned, when another was formed over 
it. In the outer basin of the altar were found the traces of a 
number of pieces of timber, four or five feet in length, and 
six or eight inches in diameter. These had been partially 
burnt, and the carbonised surface had preserved their casts in 
the earth, although the wood itself had entirely perished. The 
pieces of wood had been covered up whilst still burning, for 
the earth around them was slightly baked. The relics found 
mixed with the ashes in the central basin consisted of fragmen- 
tary pottery, some leaf-shaped flint implements, an arrow-head 
of obsidian, a number of arrow-heads of hyaline quartz, two 
copper chisels, several tubes formed of thin strips of copper, 
two carved stone smoking-pipes, and the other objects exhibited 
in Cases C 34 to C 36. Only a single fragment of partially cal- 
cined bone was found on the altar. It was the patella of the 
human skeleton. 
Mound No. 4, ''Mound City." 
This mound is oblong in shape, and measures at the base 
ninety feet in its longest and sixty feet in its shortest diameter. 
It is six feet in height, and has two sand-strata. The altar in 
this mound was remarkable from its depth, which was twenty- 
two inches, the hollow of the basin sinking a foot or more 
below the original surface of the soil. Nothing was contained 
in the basin, except a layer, about five inches in thickness, of a 
substance resembling lime mortar. Mingled with this were 
fragments of a few calcined shells.
