It also became necessary to conduct an extensive written correspond- 

 ence, wliicli extended through a period of about one year. Considera- 

 ble interest was manifested in the general subject, and much valuable 

 information was obtained concerning local forest conditions. The facts 

 collected with respect to the numerous irrigation systems of the region 

 were not so full and explicit as was desirable, but served a useful pur- 

 pose in the preparation of my report. 



Between the months of April and December, 188G, I visited many of 

 the principal points in Colorado and the several Territories included in 

 this examination. By personal investigation and inquiry in the various 

 localities, I was enabled to obtain much useful information relating to 

 the subject, and to verify statemeuts derived from other sources. 



For most timely and valuable assistance rendered me in this con- 

 nection grateful acknowledgment is due to ex-Governor Benjamin H. 

 Eaton, George G. Merrick, esq., Hon. \Viliiam X. Byers, Capt. Edward 

 L. Berthoud, C. E., Prof. A. E. Beardsley and Blair Burwell, C. E., of 

 Colorado; Samuel Ellison, esq., General H. M. Atkinson, H. Hartman, C
