THE author of this work was entrusted with the classification of the 

 Smithsonian Archaeological and Ethnological Collections before they were 

 transferred to Philadelphia, to form a part of the United States Government 

 Representation at the International Exhibition of 1870. 



While thus engaged, he found time to prepare the following account, which, 

 though far from being exhaustive, will at least serve to show what ample 

 means the National Museum presents for the study of North American archae 

 ology. 



JOSEPH HENRY, 



Secretary S. I. 



SMITHSONIAN INSTITUTION, 



Washington, August, 1876.
