TJ'pper Bagshot. ft. in.

Bracklesham. 



3. Yellow sand, with irony concretions ; a few casts of a Turritella-\\\Q 



univalve , 2 6 



4. Yellowish, reddish, and light-green sand, with laminae of nearly 



white clay 3 



The Bracklesham green sand and dark clays crop out along the 

 line to the north of the station (see Q. J. G. S. xlii. p. 407, fig. 1). 



The well at Wellington College (41) passed through 22 feet of 

 Upper Bagshot sand before reaching the pehble-bed at the base 

 (Mem. Geol. Surv. iv. p. 425 ; Q. J. G. S. xli. p. 494). There are 

 several good sections in Upper Bagshot near the College, from one of 

 which, at the butts in Edgebarrow hill, we obtained a cast of a bivalve. 

 There is a small Upper Bagshot section at the point marked 42 

 (Crowthorne), and several good ones in Lodge Hill round the Broad- 

 moor Lunatic Asylum, from one of which Mr. Whitaker informs us 

 casts of shells have been obtained. 



There is also a good section at Sandhurst, on the South-Eastern 

 Railway (43), and from it we have several casts of univalves and 

 bivalves. 



Attention has been called to a small and very detached Upper 

 Bagshot outher close to Highclere Station by Mr. Irving, and a sand- 

 pit on the 500-feet contour-line a little to the south-west of the 

 Station furnishes a good section in it. The sand is yellow, irregu- 

 larly bedded, with little or no clay, and with many irony concretions. 

 Mr. Herries has found several casts of shells in the sand, unfortu- 

 nately not sufficiently well preserved to be specifically identified,, 

 but very like the usual Upper Bagshot casts.
