WELL-SINKINGS ON LANSDOWN, BATH 



BY THE 



REV. H. H. WINWOOD, M.A., F.G.S. 



[Plate IX.] 

 {Read December 10th, 1912) 



Three wells have been recently sunk on Lansdown, Bath. 



The first was sunk in 1908, and a record of the strata 

 passed through was published in the Geological Magazine for 

 1909 (p. 119). 



During 1912 two other wells have been sunk, but the 

 sinking of one of them is not yet complete. 



It is very desirable that records of the strata passed 

 through in sections open only for a short time should be pub- 

 lished, and attention called to any particular features. 



Lansdown, I may remind you, is an elevated plateau cap- 

 ped with Great Oolite, and 780 feet above Ordnance-datum at 

 its highest point. To the south-east, on the opposite side of 

 the Avon Valley, " Brown's Folly," the highest point, is only 

 600 feet above Ordnance- datum. This hill, also, is capped 

 with Great Oolite. 



Notwithstanding the comparatively short distance be- 

 tween these two elevations, some three miles as the crow flies, 

 the upper beds composing the two hills are entirely different. 



Before discussing this matter, however, the details of the 

 strata in the three wells must be given.
