6th.  A plate of iron which had become an oxyde, but before it was disturbed by the spade resembled a plate of cast iron.  The mirrour answered the purpose very well for which it was intended.  This skeleton had also been burned like the former, and lay on charcoal and a considerable quantity of wood ashes.  A part of the mirrour is in my possession, as well as a piece of brick taken from the spot at the time.  The knife or sword handle was sent to Mr. Peal’s Museum, at Philadelphia.

To the southwest of this tumulus, about 40 rods from it, is another, more than 90 feet in height, which is shown on the plate representing these works.  It stands on a large hill, which appears to be artificial.  This must have been the common cemetery, as it contains an immense number of human skeletons of all sizes and ages.  The skeletons are laid horizontally, with their heads generally towards the center and the feet towards the outside of the tumulus.  A considerable part of this work still stands uninjured, except by time.  In it have been found, besides these skeletons, stone axes and knives, and several ornaments, with holes through them, by means of which, with a cord passing through these perforations, they could be worn by their owners.  On the south side of this tumulus, and not far from it, was a semicircular fosse, which, when I first saw it, was 6 feet deep.  On opening it was discovered at the bottom a great quantity of human bones, which I am inclined to believe were the remains of those who had been slain in some great and destructive battle:  first, because they belonged to persons who had attained their full size, whereas in the mound adjoining were found the skeletons of persons of all ages; and, secondly, they were here in the utmost confusion, as if buried in a hurry.  May we not conjecture that they belonged to the people who resided in the town, and who were victorious in the engagement?  Otherwise they would not have been thus honorably buried in the common cemetery.

Chillicothe mound.—­Its perpendicular height was about 15 feet, and the diameter of its base about 60 feet.  It was composed of sand and contained human bones belonging to skeletons which were buried in different parts of it.  It was not until this pile of earth was removed and the original surface exposed to view that a probable conjecture of its original design could be formed.  About 20 feet square of the surface had been leveled and covered with bark.  On the center of this lay a human skeleton, over which had been spread a mat manufactured either from weeds or bark.  On the breast lay what had been a piece of copper, in the form of a cross, which had now become verdigris.  On the breast also lay a stone ornament with two perforations, one near each end, through which passed a string, by means of which it was suspended around the wearer’s neck.  On this string, which was made of sinews, and very much injured by time, were
