456 GEOLOGY OF THE DENVER BASIN. 



62. The Home Artesian well, on Tenth avenue between Rogers and 

 Gilpin streets, was sunk in May, 1885. It is 685 feet deep, and is cased 

 with 8-inch drive-pipe to bed rock and with 5i-inch casing- to within 15 

 feet of the water-bearing sandstone. The original flow was 45,000 gallons 

 per day; the pressure, sufficient to throw water 30 feet. This well originally 

 supplied three blocks and was paid for by ninety shareholders, the total cost 

 being $2,500. In 1890 data concerning it could not be obtained, but it 

 had probably been abandoned. 



63. The well at the Gas Works, near the corner of Wewatta and 

 Nineteenth streets, was completed in June, 1884. It is 500 feet deep, and 

 is cased for 25 feet with 10-inch, for 300 feet with 6§-inch, and for 449 

 feet with 5|-inch pipe. Two flows have been utilized, the first at 320 and 

 the second at 495 feet, originally yielding, together, about 300,000 gallons 

 per day. This had decreased to 150,000 in February, 1886, and in 

 December, 1890, the water was pumped. A decrease of about 50,000 

 gallons was noticed when the Steam Heating Company's well and the well 

 at the Union Depot were being pumped. 



65. The Steam Heating Company's well, at the corner of Nineteenth 

 and New Haven streets, was sunk in the latter part of 1883 to a depth of 

 325 feet. It is cased with an 8-inch drive-pipe to bed rock and with 6-inch 

 pipe to a depth of 248 feet. A seed-bag packing was used at 245 feet in a 

 very hard rock. The original discharge was estimated at 200,000 gallons 

 per day. This had decreased about three-fourths in February, 1886, and in 

 December, 1890, the well for some time had been abandoned. The well 

 was much affected by the sinking of the Union Depot and Gas House 

 wells. The water has a temperature of 52° F. The using of this water 

 in conjunction with that of ordinary wells for boiler purposes illustrates 

 the wasteful uses to which the artesian supply of the city of Denver was 

 often put. 



Intimately related to this well are wells 63, 67, and 73, respectively 

 the wells of the Gas Works, Mr. Tiernan, and the Flectric Light Com- 

 pany. The flows and pressures of each of these wells have been notably 

 stronger in summer than in winter, due, it is believed, to the diminished 

 requirements of the Steam Heating Company in summer.
