GREEN OR CHLORITE SAND. • 75 



Hurstperpoint, it forms several banks of low elevation, but the sections 

 which they present are inconsiderable and uninteresting. 



On the south side of the turnpike gate at Stone-pound, the sand is of 

 a reddish brown colour, mottled with yellow ; on the north it lies beneath 

 an alluvial deposit of, 



1. Loam and ochraceous clay, about three or four feet. 



2. Blue clay, containing a large proportion of sand, five feet. 



3. Yellowish grey sand, from eight to ten feet. 



4. Eeddish brown sand; 

 these strata dip to the south. 



The httle town of Ditchhng, situated near the foot of the Downs, 

 stands upon a low mound or hillock of this deposit. Here the sand is of 

 various shades of red and yellow, interspersed with white ; and is inclined 

 to the south, dipping beneath the blue chalk marl, which bassets out from 

 under the chalk hills in the vicinity of the town. 



South of Beech wood Green* the sand rises to the surface, and forms a 

 bank about eight feet high ; in this spot it perfectly resembles the chlorite 

 sand of Wiltshire. Near Cooksbridge, in sinking the well attached to 

 the residence of Mr. Warren Lee, chlorite sand was also found at the depth 

 of forty-five feet, beneath the blue chalk marl. Other locaHties of this 

 bed occur in the vicinity of Lewes, of which the following are the most 

 remarkable, and will serve to convey some idea of its course through this 

 part of the county.
