Mr. W. "Whitaker on some Surrey Wells. 149 



Thickness Depth 

 [Upper] Chalk. The surface smooth. The top foot 

 bored in all directions with oval holes of all sizes 

 up to J inch diameter, some reaching a depth of 

 over 12 feet ; all filled with grey sand. Many 

 flints, in layers 1^ to 2^ feet apart (with few 

 breaks), and some between the layers : a thick 

 continuous layer, with black clay underneath, at 

 the depth of 389 feet 180 470 



This differs from the older section in starting at a rather 

 higher level, so that the depth to the Chalk is greater. The 

 Reading Beds are somewhat thicker, whilst the Thanet Sand is 

 less than half the thickness.

Communicated by Mr. H. H. French, who got information 

 from the well^sinker's foreman, and from specimens. 



Water rose 10 feet above the ground, but was said not to be 

 good. When the flints above the Chalk were broken through the 

 water broke in and drove out the workmen. [According to a 

 short notice in ' The Engineer,' vol. iv. p. 27, water was found 

 at the depth of 810 feet. The supply seemed very poor in 1887.]
