RECONNAISSANCE OF PART OF WESTERN ARIZONA. 
where it was used for irrigation; but during the last few years this 
seepage has disappeared. 
Harrisburg. — Near Harrisburg, at the point where the wash drain- 
ing the McMullen Valley passes through the constriction between 
the mountains, a centrifugal pump has been established, and water 
is obtained in sufficient quantities to irrigate a small ranch. This 
supply is local and limited in amount. 
Other wells. — At a number of places in McMullen Valley, in the 
Cactus Plain, and in the plains of the southern extremity of the region, 
wells were reported; but nowhere was ground water encountered in 
sufficient quantities or near enough to the surface to warrant any 
attempt at development for irrigation.

DEEP-WELL TEMPERATURES. 
Temperature readings taken at two of the deep wells are given in 
the following table. The results obtained at Yucca are probably 
more satisfactory than those at Nelson, as conditions were more 
favorable for satisfactory observation. At Nelson the thermometer 
was not in the water at the upper horizon tested, while at Yucca it 
was under water at both horizons. The increase of temperature 
downward in the Yucca well was 1° F. for 55 + feet. That in the 
Nelson well was 1° F. for 68+ feet.
