The little stone vaults in the shape of bee-hives noticed and figured in the articles in Science and the American Naturalist, before referred to, discovered by the Bureau assistants in Caldwell County, N. C., and Sullivan County, Tenn., are so unusual as to justify the belief that they are the work of a particular tribe, or at least pertain to an ethnic type. Yet under one of the large mounds at Charleston, on the bottom of a pit dug in the original soil, a number of vaults of precisely the same form were found, placed, like those of the Sullivan County mound, in a circle. But, though covering human remains moldered back to dust, they were of hardened clay instead of stone. Nevertheless, the similarity in form, size, use, and conditions under which they were found is remarkable, and, as they have been found only at the points mentioned, the probability is suggested that the builders in the two sections were related. There is another link equally strong. In a number of the larger mounds on the sites of the "over-hill towns," in Blount and Loudon Counties, Tenn., saucer-shaped beds of burnt clay, one above another, alternating with layers of coals and ashes, were found. Similar beds were also found in the mounds at Charleston. These are also unusual, and, so far as I am aware, have been found only in these two localities. Possibly they are outgrowths of the clay altars of the Ohio mounds, and, if so, reveal to us the probable use of these strange structures. They were places where captives were tortured and burned, the most common sacrifices the Indians were accustomed to make. Be this supposition worthy of consideration or not, it is a fact worthy of notice in this connection that in one of the large mounds in this Kanawha group one of the so-called "clay altars" was found at the bottom of precisely the same pattern as those found by Squier and Davis in the mounds of Ohio. In these mounds were also found wooden vaults, constructed In exactly the same manner as that in the lower part of the Grave Creek mound; also others of the pattern of those found in the Ohio mounds, in which bark wrappings were used to enshroud the dead. Hammered copper bracelets, hematite celts and hemispheres, and mica plates, so characteristic of the Ohio tumuli, were also discovered here; and, as in East Tennessee and Ohio, we find at the bottom of mounds in this locality the post-holes or little pits which have recently excited considerable attention. We see another connecting link in the circular and rectangular inclosures, not combined as in Ohio, but analogous, and, considering the restricted area of the narrow valley, bearing as strong resemblance as might be expected if the builders of the two localities were one people.
