VII. PEKRY COUNTY — EARTH-WORKS, ETC. 13 



Jacktown, who use the stone for cellar walls. This consists of the coarse-grained 

 sandstone of the coal series, and constitutes an excellent material for rough walls. 



I did not observe any permanent supply of water in the neighborhood, or any 

 reservoirs within the enclosures, which might otherwise be regarded as defensive 

 work. The largest diameter is seven hundred and fifty feet; the shorter six hun- 

 dred. The interior space rises above the well and ditch several feet, in an oval or 

 rounded form. One-fourth of a mile to the north-east is another stone mound, like 

 those within the work, which is fifteen feet high, and composed of loose sandstone. 



About one mile and a half to the south-west, and on the south side of the 

 National Koad, on sec. 10, T. 19, R. 17, is a very large stone mound, originally 

 forty feet high ; with a base, one hundred and eighty feet in diameter. 



Fifteen feet of the apex was removed, many years since, by a believer in Robert 

 Kid's treasures, and a cavity sunk nearly to the bottom with much labor. It is 

 even now a commanding object, rising among the trees of a thrifty western forest. 

 The stones are thrown together promiscuously, but in the general form of a regular 

 cone. Some of them have been carried away for masonry. Stone mounds were 

 doubtless made for the same purposes as the earthen ones, the loose fragments of 

 rocks being convenient, and more easily carried into place than earth. Walls of 

 the same material are sometimes found, as well as some of earth and stone mixed. 



I have nowhere seen, nor ever heard of, the mark of a tool on any of these 

 stones.

STONE WORK, PERRY COUNTY, OHIO. 



This is found in Perry County, five miles north-west of Somerset, Sec. 21, T. 16, 

 R 17. 



The wall is, and must have been very slight, not, on an average, as large as the 

 stone fence of the New England farmer. The stones may have been heaped to- 

 gether with more regularity than they now present, but were not dressed. At the 

 points, a, a, a, the wall increases in volume, like a mound or tower ; but, in general, 

 it is not above one foot high and ten feet broad ; its greatest height does not exceed 

 four feet. The ground is not strictly inaccessible, but difficult of approach, and at 

 the steepest places the wall is built close to the edge of the bluff. 



At b, b, the rock, a coarse conglomerate, is bare, and a perpendicular fall, of 

 several feet, is exhibited, with large detached blocks, and here there is no wall. 

 At several other points, large detached blocks, not transported, but in place, form 

 part of the wall. The builders do not appear to have employed great mechanical 

 forces, for detached rocks, and such as two or three yoke of oxen could move,
