and under the surface of the plateau, though none were discovered in the circle or nearer than 200 yards of it. They were sometimes mingled promiscuously with charcoal and ashes, but were usually in whole skeletons lying horizontally, though some were in a sitting posture; they were within from 1 to 3 feet of the surface, without any apparent system, except that they were always covered with a layer of hard earth. A trench cut through the long mound of this group, No. 1, revealed near the center an oblong pile of sandstones, beneath which was found a rude stone coffin, formed by first placing flat sandstone slabs on the natural surface of the ground, then other slabs at the sides and ends, and a covering of similar stones, thus forming a cist or coffin about 6 feet long and 18 inches wide. Within this, extended at full length, with the head west, was the skeleton of an adult, but too much decayed for preservation. With it were some stone chips, rude stone scrapers, a _Unio_ shell, and some fragments of pottery similar to those dug up in the circular enclosure. The mounds on the sand butte marked _C_, Plate I, which is something over 100 feet high, were opened and found to be in every respect similar to those already mentioned, showing them to be the work of the same people who built the others. The three mounds in the square enclosures marked _D_, (Plate I), were also opened, with the following results: The largest, oval in form, 30 feet long, about 20 feet broad and 4 feet high, was found to consist of a top layer of loose sand 1 foot thick, the remainder of hard yellowish clay. In the latter were found several flat sandstone fragments, and beneath them, on the original surface of the ground, a much decayed skeleton, with which were a few stone chips, _Unio_ shells, and fragments of pottery. The second in size, 18 feet in diameter and 3 feet high, although covered with a layer of sand, was mainly a loose cairn of sandstones, covering traces of human bones, charcoal, and ashes. The third was found to be similar to the second, but in this case the pile of stones was heaped over a mass of charred human bones, mingled with which were charcoal, ashes, and fragments of pottery. Fragments of pottery were found in abundance in the circle, in the mounds, in the washouts, and in fact at almost every point in the area covered by the group. Judging by the fragments, for not a single entire vessel was obtained, the prevailing forms were the ordinary earthen pot with ears, and a flask or gourd-shaped vase with a rather broad and short neck, often furnished with a lid. The paste with which this pottery was made had evidently been mixed with pounded shells. The only ornamentation observed consisted in the varied forms given the handles or ears and indentations and scratched lines.
