GEOLOGY. 



Boring at Woodhali Spa. — A new well is being- sunk by 

 Mr. R. Adolphus Came for the purpose of tapping the noted 

 Woodhali Spa mineral water. The well has already reached a 

 depth of over 250 feet, and is still in hard blue clay. Judging 

 from the fossils recently turned out — Gjyphea dilatata, Ammonites 

 cordatiis, Belemnites O-wenii, Thracia depressa, etc. — the work is 

 now proceeding in the Upper Oxford Clay, and it is estimated 

 that the mineral spring will be reached at something like 550 feet. 

 Mr. Came is exercising' great care in preserving the various rock 

 specimens and fossils as they are found, with their relative 

 depths, and this may lead to a better understanding of the 

 underground strata in this part of Lincolnshire. — Henry 

 Preston, Grantham.
