According to Messrs. Baker, who made the boring, the depth is 912i 



As there are sometimes considerable gaps between the speci- 

 mens, it is difficult to classify the beds. The Weald Clay seems 

 to go down to 553 feet, and the Hastings Beds may begin at 

 583. On the other hand, it is possible that the Weald Clay may 

 reach deeper down (? to 833 feet), though this would give an 

 excessive thickness to the formation. Under these circum- 

 stances it is clearly out of the question to attempt a division of 

 the Hastings Beds.

42| feet above Ordnance Datum. 



Shaft 320 feet ; the rest bored. 



Galleries from 314 to 320 feet down, in various directions, of 

 a total length of 4492 feet (1894), the chief one N.N.W. to the 

 old well. Another, southward, has just touched the junction of 

 the Tertiary beds with the Chalk at about 1000 feet from the 

 well (as the crow flies), showing that there is a slight southerly 

 dip. Probably some further length of gallery will be driven.
