{Concluded from the January Number, page 18.) 



Tj^ROM the point K northward to the stile leading to the road on 

 X; to the To wan Head the killas comes to the top, but just short of 

 the stile there is a section of another hill-wash-dune sliowing about 

 5 feet, but not exposing the base. Land shells are abundant towards 

 the top, especially at 1 ft. 3 in. and 2 feet from the surface, but the 

 lower portion contains very few. The Ilelix nemoralis zone lies just 

 below. This section yielded the flint flake found by Mr. Warren. 



Immediately on crossing the stile a deep narrow cove comes right 

 up to the path on the left-hand side, and on the top of a thin layer of 

 ' head' which caps the killas the base of the Ilelix nemoralis zone 

 can be seen. It consists of reddish ochreous earth, with fragments of 

 Mytilus, shells of Patella, and burnt (?) stones, jjassing up into sand 

 with land shells. The greater portion of the zone, however, forms 

 the floor of the path. Between the latter and the head of Hedge 

 Cove on the east side of the neck of land (where is the quarrj- section 

 noted by the writer in 1900) is a big hill- wash-dune divided bj- the 

 road. The section on the east side (T), which was clear in 1900, 

 is now nearly all talus. A small patch of Mytilus, 1 foot from the 

 top, appears at one point. 



The floor of the ledge by which this section is approached is formed 

 by the Ilelix nemoralis zone, which is perfectly visible in the cutting 

 leading down into the cove as well as in the edge of the ledge, and it 

 is separated from the killas by only about 6 inches of 'head.' It 

 consists at the base of reddish ochreous loam passing up into somewhat 

 firm yellow sand that contains many shells common to the later phase, 

 notably some very tine Helicella Barbara. In this it resembles the 

 section at E. The zone was also traceable round the seaward face of 

 the dune. 



Opposite the Lifeboat House in the sides of the cutting for the life- 

 boat slip, the zone is again shown, reddish ochreous in colour, but 

 containing no shells, while there are but few molluscan remains in the 

 2 to 3 feet of overlying, later-date sands. 



Just north of the Lifeboat House a deep gully cut right down to the 

 old platform (?) rues right athwart the neck of land, and is crossed by 

 a narrow bridge. The Ilelix nemoralis zone crops out on both sides of 

 this gully and is of reddish ochreous colour, about 1 foot thick. On 

 the west side of the bridge (M) it was full of shells (see table, p. 84), 

 but on the east side was barren. This is Mr. Warren's point ' D.' 



On the west side next the Lifeboat House the zone is overlain 

 by masses of broken slate, probably the result of building operations, 

 for on the east side about 2 feet of hill-wash-dune caps it. 



Immediately on crossing the bridge the zone is seen on the surface 

 just where a slope leads down into the gully ; here one type shell 

 occurred. Three yards on, the zone appears in the side of the path to 

 the beach (N), and is about 9 inches thick, but contains no shells.
