Mounds of stone.—­Two such mounds have been described already in the county of Perry.  Others have been found in various parts of the country.  There is one at least in the vicinity of Licking River, not many miles from Newark.  There is another on a branch of Hargus’s Creek, a few miles to the northeast of Circleville.  There were several not very far from the town of Chillicothe.  If these mounds were sometimes used as cemeteries of distinguished persons, they were also used as monuments with a view of perpetuating the recollection of some great transaction or event.  In the former not more generally than one or two skeletons are found; in the latter none.  These mounds are like those of earth, in form of a cone, composed of small stones on which no marks of tools were visible.  In them some of the most interesting articles are found, such as urns, ornaments of copper, heads of spears, &c., of the same metal, as well as medals of copper and pickaxes of horneblende; * * * works of this class, compared with those of earth, are few, and they are none of them as large as the mounds at Grave Creek, in the town of Circleville, which belong to the first class.  I saw one of these stone tumuli which had been piled on the surface of the earth on the spot where three skeletons had been buried in stone coffins, beneath the surface.  It was situated on the western edge of the hill on which the “walled town” stood, on Paint Creek.  The graves appear to have been dug to about the depth of ours in the present times.  After the bottom and sides were lined with thin flat stones, the corpses were placed in these graves in an eastern and western direction, and large flat stones were laid over the graves; then the earth which had been dug out of the graves was thrown over them.  A huge pile of stones was placed over the whole.  It is quite probable, however, that this was a work of our present race of Indians.  Such graves are more common in Kentucky than Ohio.  No article, except the skeletons, was found in these graves; and the skeletons resembled very much the present race of Indians.

The mounds of Sterling County, Illinois, are described by W.C.  Holbrook[20] as follows: 

I recently made an examination of a few of the many Indian mounds found on Rock River, about two miles above Sterling, Ill.  The first one opened was an oval mound about 20 feet long, 12 feet wide, and 7 feet high.  In the interior of this I found a dolmen or quadrilateral wall about 10 feet long, 4 feet high, and 4 1/2 feet wide.  It had been built of lime-rock from a quarry near by, and was covered with large flat stones.  No mortar or cement had been used.  The whole structure rested on the surface of the natural soil, the interior of which had been scooped out to enlarge the chamber.  Inside of the dolmen I found the partly decayed
