relieved them from tlieir embarrassment by undertaking to sink 

 the vrell on the principle of ''no cure uo pay." These gentlemen 

 were so confident of success, that they not only undertook to sink 

 the well ' to the required depth (400 feet) for the estimated 

 price, but also guaranteed a supply of 75 gallons of water per 

 minute. This determined the Council to undertake the work. 

 Supposing it successful, the great volume of water which they 

 requhed for their cascade, basins and fountains, and which formed 

 by much the greatest part of what they would have had to pay 

 the Water company for, would be supplied, and even although 

 this water should turn out to be unfitted for gardening purposes, 

 and it should be found necessary to procure what was re- 

 quired for them from a Water company, a large saving would 

 still be effected by getting the main supply from the Artesian 

 well. 



The work has now been completed, the well bored, and the 

 decision of the Council, as well as the confidence of the engineers, 

 has been justified by the result. Kfit only has the ^vell been 

 sunk at the estimated cost, and water been found at the expected 

 ^lepth, but it has been found of tlie purest and softest quality, 

 ^nd in such abundance, that, instead of supplying merely from 

 100,000 to 110,000 gallons in the 24 hours (the quantity stipu- 

 lated for), it can readily supply a million gallons in that time, 

 if larger pumps and more powerful engines were employed. 

 The total depth sunk and bored is 401 feet — a well] having been 



sunk to the depth of 226 feet, and a bore thereafter carried 

 down 175 feet farther. 



The accompanying woodcut shows the nature and depth of 

 the geological formations through which the well passed. For 

 the sake of contrast, a similar cut of the Ai'tesian well which 

 supplies the Trafajgar-square fountains, the Palaces and Public 

 Offices, is placed alongside of it- The latter sketch, so far as the 

 strata and their depths are concerned, very well represents the 

 usual relations of these as found in numerous other Artesian wells 

 which have been sunk in the Loudon basin. It will be seen 

 that the strata at the spot bored by the Society differ somewhat 

 from the others — the London clay, especially, being found of 

 much greater depth than is usually the case. It would appear 

 as if, in ancient days, the spot where Kensington Gore now 

 stands, had been one of the deep parts of the basin in which the 



London clay was being deposited. The two wells, however (that
