To the Senate of the United States:
I transmit herewith a communication from the Department of the Interior and the papers which accompanied it, being the first part of the results of investigations by Henry R. Schoolcraft, esq., under the provisions of an act of Congress approved March 3, 1847, requiring the Secretary of War "to collect and digest such statistics and materials as may illustrate the history, the present condition, and future prospects of the Indian tribes of the United States."
