§ 89. These drain waters present as great a variety as I 
would probably have obtained had I taken a great number from 
other localities. I hope and think that they represent such drain 
waters as we have in this section of Colorado. An examination 
of them shows that they contain relatively considerably more sodic 
carbonate than the ground waters, but less potassic salts. 
§ 90. The drain on Mrs. Calloway’s ranch is 500 feet long, 
four feet deep at its upper end, nine feet at the lower and has been 
open for some years. The rainfall during March, April and May 
of the year 1900 amounted to 13.38 inches, and the sample being 
taken July 23rd, was taken subsequently to the irrigation, if any 
were applied, which was probably the case, though I have no 
specific information on this point. Such were the conditions pre-
