386 GEOLOGY OF THE ISLE OF PURBECK. 



if the visitor's leisure will permit : these are Mupe 

 Cove, which is situated in Worbarrow Bay (see 

 lign. 31, p. 370) ; Stare Cove,* near Lulworth ; 

 and Man-of-War Cove, half a mile further to 

 the west, so called from a long rock at the 

 entrance, named the Man-of-War. In each of 

 these bays the same geological phenomena are 

 observable. They may all be approached from the 

 land, but are seen and studied to most advantage 

 from the water. 



Durdle, or Barn-door Cove, is remarkable for a 

 natural perforation or archway, formed by the 

 waves in a projecting crag of the nearly vertical 

 Portland oolite, which bounds the eastern cape of 

 the Bay. This arch, commonly called the Barn- 

 door, is large enough to admit the passage of a 

 boat with the sails up; and in very fine weather it 

 is customary for the pleasure parties from Wey- 

 mouth to sail through it. The western cape of the 

 bay is composed of vertical strata of chalk and 

 flint, and is called Bats Comer (see lign. 31, p. 370). 

 This bay, therefore, differs from those above de- 

 scribed, in presenting but one section of the strata, 

 which commencing with the chalk on the west, and 



* Slure Core,— so called from several caverns through which the sea dashes 

 with a loud roar. In this cove the contortions of the Purbeck heds are very 

 grotesque and remarkable. PI. xliv. of Mr. Webster, is a line view of this
