951 Hi 



Mr. Belsham, C.E., formerly of the Diamond Rock Boring Co., who 

 had charge of the work, states that water rose to about 30 feet from the 

 surface, and its level was maintained during the whole of the work. He 

 considers that the water escaped through a fissure at that level.

 constructed hy Mr. Tilley, London. Boring by the North of England 

 Rock Boring Company, 1876. Site and original works suggested hy
