held its shape after they had disappeared. Finally, the construction 

 of the mound was intermittent. 



Excavation of a Low Mound in Pike County. 



A mile north of Wakefield, in Pike County, on the Barnes farm, 

 are the enclosures figured by Squier and Davis as the "works in Seal 

 Township." Near the south-east corner of the square enclosure is a 

 mound, now about three feet high and sixty feet in diameter, sur- 

 rounded by a ditch and embankment. A circle 25 feet across was 

 laid off on the highest part of this and the earth removed to the sub- 

 soil. 



About eight feet northwest of the center, and 16 inches above the 

 original surface were two or three fragments of human skull ; and 

 between three and four feet south of them portions of human femora; 

 these probably were the remains of a body that had been laid 

 extended with head to the north. No other human remains were 

 found in the structure. 



Eleven feet south of the center were several small pieces of mica, 

 some of them fragments of trimmed and perforated pieces, others 

 rough flakes split off from a larger piece; on them lay nine flint 

 blocks or cores, evidently raw material for implements; these were 

 partially covered with a large sheet of mica ; one of the blocks was 

 chipped into a rude hatchet-form. A foot east of these were two 

 gorgets; one was of close-grained slate, well made, with a single per- 

 foration; the other of micaceous sandstone with two perforations. 

 Three feet east of these was a deposit containing a finely wrought 

 flint knife, a rough and a broken arrow-head, a flint block like those 

 first found, and a sheet of mica. These were all at the same level 

 as the human bones found on the opposite side of the mound ; but 

 there was no evidence of a burial at the place they occurred. The 

 flint blocks were irregular fragments of larger nodules, with a chalky 

 exterior, a coating of silicate of lime, and the concretionary structure 

 well marked in some. No flint of this character has ever been found • 

 m place in Ohio; a similar stone occurs abundantly near the Wyan- 

 dotte Cave in southern Indiana, but is not known to exist at a nearer 

 point.
