It also became necessary to conduct an extensive written correspond- 
ence, which 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, 1886, 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 suoject, and to verify statements 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. William N. Byers, Capt. Edward 
L. Berthoud, C. E., Prof. A. Ei. Beardsley and Blair Burwel!, C. E., of 
Colorado; Samuel Ellison, esq., General H. M. Atkinson, H, Hartman, C. —
