252 ABORIGINAL SITES ON TENNESSEE RIVER. 
on Tennessee river, as we have stated elsewhere, 42 feet in height, quadrilateral 
with a flat top, is not rectangular, one end being longer than the other. Neither 
sides nor corners are directed in a significant manner. The mound, the sides 
of which are so steep that they are ascended with difficulty, apparently 
has had at the eastern side a causeway, now almost worn away. The basal 
diameters of the mound are 310 feet NE. by E. to SW. by W., and 230 feet 
SE. by S. to NW. by N. The diameters of the summit-plateau in the same 
directions, respectively, are 145 feet and 94 feet. The ends, however, of the 
plateau were 86 feet and 50 feet. 
Ето. 31.—Vessel of earthenware. Gilchrist Island, Ala. (Height 5.3 inches.) 
On the chance that burials had been made in the summit-plateau of this 
great mound, thirty-four trial-holes, none less than 4 feet in depth, were put 
down without so much as encountering a bone, an arrowhead, or a fragment of 
pottery. 
In the field adjacent to the mound were several rises just above the level 
of the surface, on which was some scattered midden debris including half of a 
banner-stone of banded slate, of the type of the double-bladed axe.
