more rapid and more frequenl changes in their composition and texture 

 than those below, and it is quite probable that in many of the wells passing 

 below this formation the flow encountered at Littleton was either absenl or 

 too small for practical purposes. 



The total capacity of the country wells, estimated from Bomewhat 

 imperfect data, was, in 1886, 1,150,000 gallons per day. This has Bince 

 been greatly increased by additional wells. 



The life of the country wells will doubtless be long, a population 

 far greater than the pre. em being required to produce an appreciable effect 

 upon the flows. 



The character of the water i- practically the same as that of the 



water from the same horizons in Denver and it- suburbs.
