The Problem of the Ohio Mounds

No other ancient works of the United States have become so widely known or have excited so much interest as those of Ohio. This is due in part to their remarkable character but in a much greater degree to the "Ancient Monuments of the Mississippi Valley," by Messrs. Squier and Davis, in which these monuments are described and figured.

The constantly recurring question, "Who constructed these works?" has brought before the public a number of widely different theories, though the one which has been most generally accepted is that they originated with a people long since extinct or driven from the country, who had attained a culture status much in advance of that reached by the aborigines inhabiting the country at the time of its discovery by Europeans.
