THE ARTESIAN WELLS OF COLORADO, 
tending to between 500 and 600 feet. The water is run 
into a reservoir, and is devoted to the raising of carp. 
With the time at my disposal, it was not possible to ar¬ 
range it so as to make a satisfactory measurement. When 
the six-incli inner pipe is reduced to three inches, it throws 
the stream nineteen feet into the air, and when reduced 
to one inch it is projected over forty feet. The accompany¬ 
ing view represents this well reduced to one inch. The two 
flows, from 932 and from 500 feet, together amount to prob¬ 
ably 600 gallons per minute. The town well cost $1,865, the 
latter $2,700, a large part of the expense being for the 
casing. 
The flow of a three-inch well of A. T. Clark, a few 
miles west of La Jara, which was 166 feet deep and was 
sunk in one-half day by six men, was ninety-five gallons 
per minute. The water rose seven inches above the cas¬ 
ing. 
In Township 42 north, Range 8 east, is the three- 
inch well belonging to Celso Espinosa, 265 feet deep, 
which throws a solid stream the full size of the casing 33f 
inches high. This seems to have decreased some, as Mr. 
Dawson informs me that he had measured it when it 
threw a stream forty-one inches high. The flow was be¬ 
tween two and three hundred gallons per minute. Several 
others in the same neighborhood, which is near where the 
Carnero sinks, are reported as having flows corresponding 
to this. 
Most of the wells have been sunk for domestic use 
only, and irrigation has not been specially considered in 
connection with them. Where the flows are large they 
are used to some extent, and sometimes small reservoirs 
have been built for storage. The three-inch well of Espi¬ 
nosa, already mentioned, is said to irrigate some 100 acres 
of hay land. J. M. Chritton writes that he was irrigating 
sixteen acres in 1889 from one well. L. W. Smith, a few
