LETTER OF TRANSMITTAL. 



Washington, D. C, January 2, 1878. 

 Sir: I have the honor herewith to traDsmit the "Catalogue of Min- 

 erals found m Colorado." It has been made as complete as possible, up 

 to date. 



A plan differing from that previously followed has been adopted. 

 So tar as practicable, analyses of Colorado minerals have been given. 

 They will aid examination and show the interest taken by specialists in 

 the minerals from this State. All available material has been utilized 

 in the preparation of the catalogue. A systematic enumeration of the 

 Colorado mineral species and references to the publications thereon have 

 been added. 



I desire here to thank those gentlemen to whom I am indebted for 

 verbal and written information. 



Hoping that the subjoined pages may meet your requirements, 

 I am, very respectfully, your obedient servant, 



FREDERIC M. ENDLICH. 

 Dr. F. V. Hayden, 



Geologist in-cliarge United States 



Geological and Geographical Survey of the Territories.
