 from specimens] . 



Water (in chalk) rose to 105 feet from surface. Fell on 

 reaching U. G. S. (to 117 feet). Practically no supply of water 

 until over 400 feet deep, when the water-level rose several feet. 

 A further sudden rise in the water-level has twice taken place 

 since, and each time accompanied by a practical increase m the 

 yield, so that we now (March, 1886) can get over 1000 gallons 

 an hour without lowering the head of water more than 25 feet 

 (526 feet deep).
