LETTER TO THE SECRETARY. 17 



party during the past year lias thrown an immense amount of executive 

 labor on me, which has exhausted my strength, and consumed my 

 time to such an extent that I have not been able to give the necessary 

 attention and study to my portion of the report. The editing of so 

 many publications is sufficient labor for one person, and yet this is the 

 smallest duty that has devolved on the geologist-in-charge. The various 

 executive duties, as correspondence, foreign exchange, settlement of 

 accounts, and the supervision of the parties in the field and office, seem 

 to increase from year to year, so that only mere fragments of my time 

 can be devoted to scientific study. 



The present annual report is submitted with the belief that it contains 

 much that is new and interesting to geologists and the intelligent world 

 generally. 



Very respectfully, your obedient servant, 



F. V. HAYDEN, 

 United States Geologist. 

 Hon. Z. Chandler, 



Secretary of the Interior.
