§ 61. Information and aid to a greater or less extent has been 
received from too many to mention. To the various Water Com¬ 
missioners, especially to J. L. Armstrong and R. Q. Tenney, of Dis¬ 
trict No. 3, and J. T. Hurley and R. J. Patterson, of Nos. 1 and 64, 
our thanks are especially due. 
By the kindness of G. H. West and D. A. Camfield, of Greeley, 
a team w T as furnished us for the measurement of the Platte, in 1895, 
and we are indebted to Receiver Trumbull, of the Union Pacific & 
Gulf Railway, for transportation where necessary during the meas¬ 
urements. 
The diagrams have been drawn by Mr. J. D. Stannard, who 
has also aided the laborious work of reduction of the observations; 
Mr. Trimble has also aided extensively in the same work, and in the 
field work, as noted in the detailed observations, and also in preparing 
and checking the tables. 
Through oversight, credit was not given, on page 32, in a part 
of the edition, to Mr. P. J. Preston, for Measurement No. 5, made 
under direction of the State Engineer.
