DETAILED ACCOUNT OF SOME RECENT EXPERIMENTS. 41 



hours' continuous pumping it was 84 feet below the top of the well, 

 which gives a fall of 49 feet, and within an hour it rose 51 feet 6 

 inches, actually 2\ feet higher than it originally was when pumping 



was first started The fall after pumping after the first few 



days appears to have been much less. Pumping was discon- 

 tinued on the 2nd April, and on the 6th May it was found that the 

 water was 32 feet from the top of the steining, and i6£ feet higher 

 than the water in the well on the opposite side of the road." 

 (Report of the Executive Engineer, dated iSth July 1887.) 



At the time of these experiments, the bottom of the 45" tube was 

 inserted into the Vindhyan rock to a distance of about four feet. 

 The circumstance of the rise of water was brought to the notice of 

 Mr. Medlicott, who was of opinion, however, that the water did. not 

 proceed from the Vindhyans : he considered that the pipes were not 

 water-tight, and that the water probably issued from some of the 

 arenaceous strata in the alluvium, perhaps one of those marked 30 

 or 32 in the list given below. The matter was also referred, at a 

 subsequent date, to Mr. Foote, who concurred in Mr. Medlicott's 

 opinion. Yet, as matters then stood, it was not possible to obtain 

 absolute certainty, which is unfortunate, because this is the only 

 boring in India that has penetrated to any depth through the 

 Vindhyans, and it would be very interesting to obtain some accurate 

 information as to the water-bearing capacity of these rocks, whose 

 stratigraphical structure is in many localities eminently suited to 

 artesian conditions. 



The water was so highly charged with salts of magnesia that it 

 was quite unfit for drinking purposes, that in the neighbouring wells 

 being on the contrary quite sweet. As it was found deficient both 

 in quality and in quantity, the experiment was discontinued and the 

 pipes were withdrawn. 



The following is the list of strata passed through in the Agra 

 boring.
