32 VREDENBURG : RECENT ARTGSIAN EXPERIMENTS IN INDIA. 



every instance developed a pressure sufficient to raise the water very 

 nearly, or quite to surface, but evidently of not much volume." 



"The last bed of sand found, however, extended from about 1,160 

 to 1,220 feet, about 13 feet of which — from 1,189 to l|202 — was a live 

 quicksand, and contained water of sufficient pressure and volume to 

 produce a flow over the top of the pipe at 6 feet below the surface, 

 26 feet above the river, amounting to about 10 gallons a minute 

 — 14,400 a day — which proved on analysis to be perfectly pure water. 

 The quantity was not sufficient to be of practical value, and the bor- 

 ing was continued in search of a more abundant supply, and in 

 order to sink the well deeper it was necessary to drive the pipe 

 down, and that cut off and effectually stopped the flow already 

 obtained." 



The boring had been undertaken in view of providing a water- 

 supply to the town of Lucknow. On account of the considerable 

 interest arising from its partial success, it was intended to make an- 

 other trial beginning with a much larger diameter (a 24-inch pipe) by 

 means of which it was hoped that a depth of 2,000 feet would be 

 reached. But it was calculated that even if the experiment were 

 entirely successful, and a copious supply discovered, it would be 

 necessary to bore a number of such wells, perhaps as many as ten, 

 so as to supply the town with sufficient water, and on account of the 

 great expense incurred in boring to such considerable depths, the 

 scheme would have been far more expensive than that of furnishing 

 the town with water from the Gumti river, even with all the addi- 

 tional expense of the plant required for raising the supply, filtering 

 it, etc. Hence the experiment was abandoned. 



The record of the Lucknow boring has been published by 

 Mr. Oldham in the publications of the Geological Survey, 1 and is 

 appended below.
