pieces of pottery, a number of shells and a few human 

 bones. The other three mounds, one of which is not 

 over ten or twelve feet in diameter and situated the fur- 

 thest to the north, were not examined internally. 



The position of all the mounds, within the enclosure, 

 which are indicated by the white circles on the cut, is such 

 as to suggest that they were used as observatories, and it 

 may yet be questioned if the human aud other remains 

 found in them were placed there by the occupants of the 

 fort, or are to be considered under the head of intrusive 

 burials by a later race. Perhaps a further study of the 

 bones may settle the point. That two races have buried 

 their dead within the enclosure is made probable by the 

 finding of an entirely different class of burials at the ex- 

 treme western point of the fortification, indicated on the 

 engraving by the three quadrangular figures at II. At this 

 point Dr. Harper, the year previous, had discovered three 

 stone graves, in which he found portions of the skeletons 

 of two a lults and one child. These graves, the stones of 

 one being still in place, were found to be made by placing 

 thin slabs of stone on end, forming the sides and ends, the 

 tops being covered by other slabs, making a rough stone 

 coffin in which the bodies had been placed. There was no 

 indication of any mound having been erected, and they 

 were placed slightly on the slope of the bank.' This kind 

 of burial is so distinct from that of the burials in the 

 mound, that it is possible that the acts may be referred to 

 two distinct races who have occupied the territory succes- 

 sively, though they may prove to be of the same time and 

 simply indicate a special mode adopted for a distinctive 

 purpose. 



The short time given to the examination of this inter- 

 esting work left many important points unsettled, and since 

 his return the relics discovered have not been looked at.
