DESCRIPTION OF THE PLATES. 29 



cliff is seen on the left of the Cove, and from that to the 

 entrance, where the oolite appears, the intermediate 

 strata occur. The upright rocks in the sea near the 

 foreground, are masses of the Purbeck beds on this side 

 of the bay, while similar blocks appear on the opposite 

 bar. The argillaceous strata on the side of the hill are 

 curiously contorted from lateral pressure. 



PI. XVIII. — West Lulworth and Cove. 



The village of West Lulworth is situated in a deep 

 valley, formed by an interruption of the chalk range 

 that extends from Handfast Point, through Corfe Castle, 

 to the coast. The Cove, which has been produced by 

 the erosive action of the sea on the chalk cliffs, is about 

 1,300 feet in diameter, and vessels of a hundred tons 

 burthen, may at all times remain here in perfect security. 



The hill immediately above the village, is the ter- 

 mination of the long ridge called the Swine's bach, 

 which is half cut into by the Cove, and presents a lofty 

 precipitous chalk cliff. Saint Adhelm's head is in the 

 remote distance ; the nearer headland, seen above the 

 Cove, is Gad Cliff. 



PI. XIX.— Durdle Cove. 



In Durdle Cove, the series of deposits from the upper 

 flinty chalk to the Portland oolite, is exposed in a nearly 

 semicircular bay, walled in by vertical sections of these 

 strata. The chalk appears on the right, forming the 

 high cliff termed Bafs Comer ; and in passing from 

 thence round the bay, the Chalk marl, Firestone, Gait, 

 Greensand, Wealden, and Purbeck strata, may be sue-
