212 E> T. Mardman — Raised Beach at Tr amove. 



The Cockle-bed was at a height of from two to three feet above 

 high- water mark. Had I not seen other sections having a direct bear- 

 ing on the above, and of some if not entire similarity to it, I should 

 have been inclined to reject bed e as of artificial origin : but, as 

 the sequel will show, there is a strong presumption that it is really 

 in situ. In a drain along a new road, being the continuation of the 

 wall to the westward, a somewhat similar section is seen :

 The shells are absent here, possibly because the former submer- 

 gence did not extend so far. The peaty layer undoubtedly corre- 

 sponds with the boggy bed of the last section. 



Five hundred yards north of the sluice-gate, and close to the 

 division of the Townlands, Ballinatin, and Drumcannon, Mr. Willson 

 has noted " Layers of Cockle-shells 2\ feet above high- water mark." 

 This has also disappeared. 



The foregoing are the only traces to be found on the west of the 

 estuary; but on crossing the Eeclamation Djdte to the other side, the 

 old beach becomes very apparent, and a little to the north, about 

 sixty yards from high-water mark, an excellent section is seen 

 (See Plate XI. Fig. 4, p. 214) :

 The height of the shell-bed is here about nine or ten feet above 

 high- water mark, and it is found extending inland in a section ex- 

 posed in a ditch, continuing into the next field. 



A little south of this, and close to high- water mark, the same section 

 is seen ; but here bed c. becomes very black, from the presence of 

 organic matter, in some places very peaty, and thickens to one foot. 

 Bed h. is sometimes a foot thick, and the height of the shell-bed is 

 seven feet above high- water mark. 



Continuing southwards in Lissellan, the peaty layer is underlaid 

 by a few thin layers of well-stratified gravel, full of shells, which 

 die out after a little distance. Further on along the shore the level 

 of the peaty bed sinks gradually, and at last is covered by a distinct 

 layer of rudely-stratified gravel, in which a few shells are found, 

 being evidently a shore deposit. This, which is about a foot thick, 

 and is covered with mould well clothed with grass, continues for 

 nearly half a mile, the height diminishing to about two feet, until it
