nished with ascending ranges of steps on the outside. The resemblance is striking, and the most reasonable explanation seems to be that in both regions mounds of this class were intended for the same uses. Figure 4 shows the works at Cedar Bank, Ohio, inclosing a mound. The mound within the inclosure is 245 feet long by 150. broad. Figure 5 shows a group of mounds in Washington County, Mississippi, some of which are connected by means of causeways. Another class of these antiquities consists of inclosures formed by heavy embankments of earth and stone. Fig. 5.-Works in Washington County, Mississippi. There is nothing to explain these constructions so clearly as to leave no room for conjecture and speculation. It has been suggested that some of them may have been intended for defense, others for religious purposes. A portion of them, it may be, encircled villages or towns. In some cases the ditches or fosses were on the inside, in others on the outside. But no one can fully explain why they were made. We know only that they were prepared intelligently, with great labor, for human uses. "Lines of embankment varying from 5 to 30 feet in height, and inclosing from 1 to 50 acres, are very common, while inclosures containing from 100 to 200 acres are not infrequent, and occasional works are found inclosing as many as 400 acres."
