The largest of the mounds was first examined, but nothing was found in it. There were no signs of burials near the slopes, and at the base, contrary to expectation, there was not found any indication of a fire having been made, and there was no charcoal. In another conical mound, although no bones were seen, there was in the centre a hollow space which contained several pieces of charred wood. A comparatively low platform mound was then opened. Two skeletons were found buried near the surface, but from their position and state of preservation, they were considered to be late interments; nothing else was found within. Finally a large mound, situated upon the extreme edge of the bluff, was thoroughly excavated, and in this there was found, as in the previously opened conical earthwork, a small hollow space in the centre. In consequence of these negative results, it was not possible to form any conclusions as to the object of Indians in raising these exceptional works. I thought it not improbable that it might have been their intention to use them, either for raised dwelling places, or for defensive inclosures which had not been completed. Their position is almost impregnable; the mounds are not placed separately but are closely joined together, so that they form a kind of embankment. The outer slopes are so close to the edge of the cliff, that they are practically a prolongation of the steep slopes, and thus present a singular parallel with portions of those embankments of Fort Ancient which overlook the valley of the Little Miami. The similarity in the methods of placing the mounds, is made additionally obvious from the fact, that there are numerous springs issuing from the upper parts of the bluff, which flow down as rivulets into the river below. There are altogether fifteen mounds on the top of the promontory; the largest of them is about twenty feet high. Upon our return to St. Paul’s, we heard that a band of Sioux had come into the neighbourhood, and were encamped amongst the woods on the opposite side of the river. As I wished to see these Indians, I crossed over to the settlement of Mendota, and after a walk of a few miles, saw their tents pitched close to the borders of a small lake. I was greeted with a loud noise of barking from their dogs, who were as numerous outside the camp of the Sioux as they usually are around the dwellings of the Kurds in Asia Minor. After overcoming some preliminary hostile difficulties with these yelping curs, I received a silent and not pressing welcome from the Indians, who were mostly squaws and children, the men having gone away temporarily upon some expedition.
