LETTER OF TRANSMITTAL. 



Department of the Interior, 

 United States Geological Survey, 

 Washington, D. C, Novemler 11, 1903. 

 Sir: I transmit herewith the manuscript for a "Catalogue and Index 

 of the Publications of the Hayden, King, Powell, and Wheeler Sur- 

 veys," prepared by Mr. L. F. Schmeckebier, of the editorial division 

 of the Geological »Survey, and recommend that it be published in the 

 Bulletin series of the Survey. 



The publications of these early Government organizations consti- 

 tute a storehouse of geographic, geologic, ethnologic, and archjeologic 

 information concerning the western portion of the United States; and 

 though their usefulness may have diminished as a result of more 

 detailed surveys and more precise work, I believe that this complete 

 catalogue and consolidated index will be welcomed by many students, 

 investigators, and librarians. 



Very respectfully, P. C. Warman, 



Editor. 

 Hon. Charles D. Walcott, 



Director United States Geologiad Survey.
