Henry W. Henshaw analyzes the Mound Builders stone carvings as representations of animals not found in the Mississippi Valley of the United States.  Identification of these subjects as accurate would serve as proof of contact between the Mound Builders and other civilizations located in remote areas such as Mexico, Central and South America.

This work was originally presented in the "The Second Annual Report of the Bureau of Ethnology to the Secretary of the Smithsonian Institution, 1880-'81.".
