ARTESIAN WELLS. 457 



73. The Electric Light Company's well, at the foot of Twenty-second 

 street, was sunk in July, 1883, to a depth of 330 feet. It has a 6-inch drive- 

 pipe to bed rock and a 4i-inch casing to a depth of 285 feet. The original 

 pressure of 30 pounds had decreased to 10 in February, 1886, and in 

 December, 1890, the water was pumped. The early decrease was caused 

 directly by the sinking of the wells at the Gas and Steam Heating Works 

 in the winter of 1883. The discharge has generally been greater in the 

 summer than in the winter. This well supplied the boilers at the works. 

 Unusual care was taken in making tight joints in casing, and in putting this 

 in place, and the well has been one of the most reliable in the city. 



81. The Savage well, on the corner of Thirty-fifth and Holladay 

 streets, was completed in March, 1884. It is 400 feet deep, cased to a 

 depth of 50 feet with 4-inch and to 339 feet with 2-inch pipe. A cement 

 packing was used. Flows were cut at 160, 220, and 370 feet. The first 

 rose just to the top of the casing, the second had a head of 33 feet, the 

 three together one of 50 feet. In February, 1886, this had decreased to 

 8 feet; the flow stopped in 1888, and in December, 1890, the water, 25 

 feet below the surface, was pumped. The 370-foot flow was that utilized. 

 A sharp decrease of 12 feet took place when the Adair, or Nichols, well 

 (No. 84 or 85) was sunk. 



87. The well at the Union Pacific Hospital, near the Grant Smelter, 

 was sunk in the latter part of 1884 to a depth of 400 feet. A flow of 

 5,000 gallons per day was secured at this depth, but this not being suf- 

 ficient the well was further sunk to a total depth of 675 feet, where a 

 heavy flow was cut that showed a pressure of 40 pounds. Three hundred 

 and ninet} T -five feet of 5|-inch and 640 feet of 4i-inch casing were used 

 without packing. This was considered one of the best wells in the city. 

 In 1886 the flows were estimated at about 90,000 gallons per day, and the 

 well was still in use in December, 1890. 



88. The well at the Grant Smelting Works has always been one of the 

 most satisfactory of the city wells. It was sunk in 1883 to a depth of 620 

 feet, and cased with 7§-inch pipe for 387 feet and with 5|-inch pipe for 556 

 feet. Three flows, at 240, 325, and 575 feet, were formerly utilized. The 

 5|-inch pipe brought to the surface the water from the main flow, which
