78 VREDENBURG ! RECENT ARTESTAN EXPERIMENTS IN INDiA, 



"The bed of stream is about 20 feet below bore-hole surface, and 

 is running about 200 feet from nearest point of bore, the width 

 would be about 30 to 40 feet in part. About 380 to 400 feet from 

 surface, I noticed a greater volume of water running over the bore 

 equal to nearly 2,ooo gallons or thereabout, and I do not think that 

 the flow of water got diminished. The lining tubes have been with- 

 drawn from hole." 



The Records of the Geological Survey contain accounts of a

where a sheet of water was struck at a depth of 14 feet, and gave 

 a permanent flow at the surface. 1 Judging from the description, 

 however, the site is in the low ground on the banks of a river, and 

 as the water was tapped at such a small depth, it was no doubt in 

 close connection with the ground-water at no great distance, the 

 case being analogous to that of the Mahi river in Gujarat, or of the 

 Ganges bridge at Benares. 



Along the east coast of the Peninsula there are several areas 

 of upper Gondwanas whose strata dip at low angles towards the 

 sea-coast, and which appear therefore suited to the existence of 

 artesian conditions. Several experiments have been made to test 

 these localities, but with small success so far. Such is the boring

Garden, near Madras. district near Madras. The work was originally 

 undertaken by the Reverend S. Dominic, Superior of the Monastery 

 at Place's Garden, and, on account of the great interest attached 

 to the experiment, Government aid was granted on various occasions 

 to enable the work to be pursued. On being consulted by the 

 Government of Madras in 1891, when the boring was nearly 300 

 feet deep, Mr. Foote stated that he had reason to believe that a
