REPORT — 1895. 



dicular, and about 88 feet in height. Since the 6-inch Ordnance map 

 of 1876 was published there has been no great loss of land, but several 

 heavy falls of cliff, amounting to some thousands of tons, as at the Corn- 

 hill Coastguard Station, two miles east of Dover, on February 23, 1891, 

 and the still larger one at the Abbot's Cliff Coastguard Station (Lydden 

 Spout) early in the present year. 



Tlie recession of the coast line westwards from Dover to Folkestone is 

 no doubt caused by the uncertain foundation of underlying Gault clay, 

 which retains the water passing through the porous chalk, the sea carrying 

 away the debris : this is particularly the case where groynes or piers at 

 right angles to the shore have intercepted the shingle coming from the 

 west, that to the eastwai'd of such obstructions gradually passing away in 

 that direction, and not being replaced by fresh accretions from the west. 

 The shore, being undefended by the shingle beach, is exposed to wave- 

 action. 



The Folkestone pier intercepts the shingle that at one time defended 

 East Wear Bay, the Folkestone Cliffs, and the West Cliffs, Dover. The 

 Admiralty Pier, Dover, has in like manner robbed the foreshores of the 

 Esplanade, Dover, and the East Cliff, Dover, of their shingle, making 

 costly revetements and sea-walls necessary.
