Washington DC.

June 14th 1870.

Dear Sir

Your very kind letter came duly to hand.1 I send you a roll of maps today through the Smithsonian Institution—2 These maps will serve to aid you in following explorers over our far west. I will send you from time to time succh books or maps as you wish to make more clear, the results of examinations in that region. I start soon for Idaho & Montana with $25,000, for another summers labors.3 Will go along the Union Pacific Railroad to Salt Lake, thence northward to the sources of the Columbia & Missouri rivers.

Hoping that you are well and will long live to work out the grand results of your studies. I remain | your sincere admirer & reader | F. V. Hayden
