The most considerable of those tumuli or sepulchral mounds, which are found in Virginia, is that on the bottoms of Grave creek, near its entrance into the Ohio, about twelve miles below Wheeling, and is the only large one in this section of the country. Its diameter at the base, is said to be one hundred yards, its perpendicular height about eighty feet, and the diameter at its summit, forty-five feet. Trees, of all sizes and of various kinds, are growing on its sides; and fallen [36] and decayed timber, is interspersed among them; a single white oak rises out of a concavity in the centre of its summit.[9]
Near to Cahokia there is a group (of about two hundred) of these mounds, of various dimensions.[10] The largest of these is said to have a base of eight hundred yards circumference, and an altitude of ninety feet. These and the one mentioned as being on Grave creek and many smaller ones in various parts of the country, were no doubt places of inhumation.[11]--Many have been opened, and found to contain human bones promiscuously thrown together. Mr. Jefferson supposed the one examined by him, (the diameter of whose base was only forty feet and height twelve) to contain the bones of perhaps a thousand human beings, of each sex and of every age. Others have been examined, in which were the skeletons of men of much greater stature, than that of any of the Indians in America, at the time of its discovery, or of those with whom we have since become acquainted.
It is a well known fact, that since the whites became settled in the country, the Indians were in the habit of collecting the bones of their dead and of depositing them in one general cemetery; but the earth and stone used by them, were taken from the adjacent land. This was not invariably the case, with those ancient heaps of earth found in the west. In regard to many of them, this singular circumstance is said to be a fact, that the earth, of which they are composed, is of an altogether different nature, from that around them; and must, in some instances, have been carried a considerable distance. The tellurine structures at Circleville are of this sort; and the material of which they were constructed, is said to be distinctly different, from the earth any where near to them.
