NOTE ON NON-MARINE MOLLUSCA OBTAINED FROM HOLOCENE 

 AND PLEISTOCENE DEPOSITS AT BUCKLAND, DOVER. 



By the Eev. E. Ashington Bullen, B.A., F.Gr.S., etc. 



Head lOth June, 1898. 



The object of this note is to draw attention to two very interesting 

 sections of Pleistocene and Holocene deposits, containing the remains 

 of Mollusca, that overlie the Head or Ruhhle Drift at Barton Court 

 Estate, Buckland, Dover, on the northern side of the valley of the 

 Eiver Dour. The deposits are at a height of about fifty feet above the 



Fig. I. 



1 . Surface soil with few angular flints, 2 feet. 



2. Dissolved out flints unworn, 9 in. to 1ft. 6 in. 



abundant. * Roman potterv. 



3. Chalk Rubble, 1 ft. to 2 ft. 6 in. 



Helix aspersa extremely- 



present river-bed, and probably 100 to 120 feet above O.D. Since 

 contours of the hills contiguous to Government fortifications are not 

 published, it is difficult to arrive at the exact level in reference to 

 mean high-water mark. 



The deposits are about a mile in a straight line from the nearest 

 cliff, and about two miles from the mouth of Dover Harbour. 



The estate is being rapidly developed for building purposes, and 

 a new road, called Heathfield Avenue, has been made on the hill 

 which terminates at Dover Castle. This road is partly made of the 

 material on the spot, and in cutting a perpendicular face on its 

 northern side the rubble drift deposit and overlying strata have 

 been cut. 



In the waste land between sections I and II living specimens of
