Be our conclusion on this question what it may, one important result of the explorations in this northern section of the United States is the conviction that there was during the mound-building age a powerful tribe or association of closely allied tribes occupying the valley of the Ohio, whose chief seats were in the Kanawha, Scioto, and Little Miami Valleys. We might suppose that one strong tribe had occupied successively these various points, yet the slight though persistent differences in methods and customs indicated by the works seem to favor the other view. Moreover, the data furnished by the burial mounds lead to the conclusion that all the works of these localities are relatively contemporaneous. Not that those of either section are all of the same age, perhaps by some two or three or possibly more centuries, but that those of one section, as a whole, are relatively of the same age as those of the other sections. Nevertheless a somewhat careful study of all the data bearing on this subject leads me to the conclusion that the Cherokees are the modern representatives of the Tallegwi, and that most of the typical works of Ohio and West Virginia owe their origin to this people. In each section there are some indications that the authors of these works followed the custom of erecting burial mounds down to the time the Europeans appeared on the continent. These evidences have not been given here, as it is not my intention to discuss them in this paper. In Ohio there are undoubted evidences of one, if not two, waves of population subsequent to the occupancy of that region by the builders of the chief works. But these were of comparatively short duration, and were evidently Indian hordes pressed westward and southward by the Iroquois tribes and the advance of the whites. THE APPALACHIAN DISTRICT. 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:
