earth three feet thick covered here a human skeleton, which was 

 lying in an east and west direction, and near this skeleton were a 

 number of arm and leg bones. The next mound was one of those 

 already explored. 



The third niuund in order eastward was fcnir feet high and thirty 

 feet in diameter. Five feet below the surface we found, in a small 

 ditch tw<j feet acrcjss, a great number of human bones — of arms, 

 legs, skulls, shoulders, etc. — all mingled together. In one of the 

 best preserved skulls, in the back part, we found the bone of a 

 fino-er in a quantity of earth. This clearly proves that the whole 

 corpse was not liuried here, but only the bony remains of human 

 beings. 



The fourth mound is two feet high and fifteen feet in diameter. 

 Nothing was found, except a few bones, about two feet below the 

 surface. 



The fifth mound was three feet high and fifteen in diameter. Here 

 we found a skeleton at the depth of three feet, lying horizontally, east 

 and west. 



The next mound — the sixth — had already been opened. 



The seventh was four feet high and thirty feet across. At four feet 

 from the surface were found two skeletons, one Ijnng east and west, 

 the other north and south. The bodies must have been here disposed 

 on the natural ground, and the earth afterward piled over them. The 

 bones were much decayed, and were accompanied by no relics. 



September 14th I opened a mound on Copper Creek, Sec. 24, Twp. 

 16, R. 4, which belonged to a group which have been so reduced by 

 long tillage of the soil, that they have disappeareil entirely, except 

 two which were situated in woodland. These two were aliout two 

 feet high and fifteen feet wide, conical in form. We made in the first 

 one an opening a few feet square, and at a dei)th (jf two and one-half 

 feet we discovered pieces of rotten black walnut wood, four feet long, 

 lying crosswise over the grave. In this grave, or excavation, and be- 

 neath the wood, was a light black earth composed of rotten grass or 

 foliage, and beneath this layer a few human bones, and close beside 

 them, a plain mound-builder's pipe and one arrow-head. 



The other mound was constructed like the one just described, and 

 we found, with a few decayed bones, two flint implements. At the 

 base of the two mounds were graves three feet deep, extending east 

 and west. The earth which was over these graves, and forming the 

 whole mound, was a black soil from the surrounding surface, and we
