The wall of this enclosure is composed entirely of boulders and broken pieces of sandstone which had been collected along the margin of the summit of the hill. These sandstones are the result of disintegration of the sandstone strata which is near the surface on the hill top. Directly east from the village site, a little more than 1300 feet, is what is known as the Baum works, which was surveyed by Squier & Davis in 1846. They described this work as the best preserved, and possessing gateways that are wider than those of any other earth-works found in this valley. They also made a survey of the mound which is situated in this village site and they described it as a large, square, truncated mound, with a base of 120 feet and having a flat top, with an area 50 feet square. The mound at that time being 15 feet high. They also say that quantities of coarse broken pottery were found on and around the mound. Thus it will be seen that the early investigators found pottery surrounding the mound and later explorations by the Smithsonian Institution show that the broken pieces of pottery found on the surface surrounding the mound were very much like the pottery found in the mound and placed with the buried dead therein. The object of the investigations carried on by the Archæological and Historical Society is to show the connection between the occupants of the prehistoric village and those who built the mound. This has been done by carefully comparing the contents of this village site with the contents of the mound as reported by the Smithsonian Institution. So far, all of the pottery and implements of bone, stone, and shell that were buried in this mound, have been duplicated in great numbers from the refuse heaps, burials, and ash pits found in the village. The village entirely surrounds the mound, but on the east it is more extensive and occupies upward of five acres of ground.
