This district, as already defined, includes East Tennessee, western North Carolina, southwestern Virginia, and the southeastern part of Kentucky. It is probable that northeastern Georgia and the northwestern part of South Carolina should be included, but the investigations in most of the sections named have not been sufficiently thorough to enable us to fix with any degree of certainty the boundaries of the district.
Although there is uncertainty in reference to the area occupied by the people who left behind them the antiquities found in this region, there can be no doubt that here we find a class of burial mounds differing in several important respects from any we have so far noticed.
Some of the most important mounds of this class found in this district were discovered in Caldwell County, North Carolina, and opened in 1882 by Mr. J. P. Rogan, one of the Bureau assistants, aided by Dr. J. M. Spainhour, a resident of the county.
As Mr. Rogan's descriptions are somewhat full, I give them substantially as found in his report:
The T. F. Nelson mound.—This mound, so insignificant in appearance as scarcely to attract any notice, was located on the farm of Rev. T. F. Nelson, in Caldwell County, North Carolina, on the bottom land of the Yadkin, about 100 yards from the river-bank. It was almost a true circle in outline, 38 feet in diameter, but not exceeding at any point 18 inches in height. The thorough excavation made revealed the fact that the builders of the mound had first dug a circular pit, with perpendicular margin, to the depth of 3 feet, and 38 feet in diameter, then deposited their dead in the manner hereafter shown, and afterwards covered them over, raising a slight mound above the pit.
A plan of the pit, drawn at the time (after the removal of the dirt), showing the stone graves and skeletons, is given in [Fig. 25].
The walled graves or vaults and altar-shaped mass were built of water worn bowlders and clay or earth merely sufficient to hold them in place.
No. 1, a stone grave or vault standing exactly in the center of the pit. In this case a small circular hole, a little over 3 feet in diameter and extending down 3 feet below the bottom of the large pit, had been dug, the body or skeleton placed perpendicularly upon its feet, and the wall built up around it from the bottom of the hole, converging, after a height of 4 feet was reached, so as to be covered at the top by a single soapstone rock of moderate size. On the top of the head of the skeleton and immediately under the capstone of the vault were found several plates of silver mica, which had evidently been cut with some rude implement. Although the bones were much decayed, yet they were retained in position by the dirt which filled the vault, an indication that the flesh had been removed before burial and the vault filled with dirt as it was built up.
Nos. 2, 3, 4, 5, 6, 7, 8, 9, and 10, although walled around in a similar manner, were in a sitting posture on the bottom of the pit. In the grave of No. 2 was found a polished celt, in that of No. 3 a single discoidal stone, in that of No. 6 two polished celts, and immediately over No. 9 a pitted stone.
