The rude type of the implements, the absence of fine pottery, and the peculiarities of the human remains, indicate a race of occupants more ancient than the "mound-builders."
Moreover, the mound-builders in the eastern half of this vast plain, being sedentary, were excellent potters.
The Cincinnati Society of Natural History (incorporated 1870) has a large library and a museum containing a valuable palaeontological collection, and bones and implements from the prehistoric cemetery of the mound-builders, at Madisonville, Ohio.
Near by are some 18th century buildings, some interesting earthworks of the "mound-builders," and a cemetery in which are buried many soldiers who fought in the War of Independence.
The pottery accompanying the remains is often elaborately ornamented, and the mound builders were evidently possessed of a higher development of taste and skill than is evinced by any of the modern aboriginal races, by whom the mounds and their contents are regarded as utterly mysterious.
