376 GEOLOGY OF THE ISLE OF PURBECK. 



Beds containing stone with small paludinse cemented toge- 

 ther by green calcareous earth; called "marble," and 

 "marble-rag," by the quarry men; 16 paces. 



About 25 paces more of the cliff are made up of brown and 

 grey clays, with bands of bluish grit, and thin beds of 

 stone. 



Contorted clays and limestones, which extend to the pro- 

 minence called Worbarrow knob ; between this point, and 

 Gad Cliff on the east, a thickness of 50 feet consists of 

 alternating layers of clays and limestones, which are also 

 much undulated. 



On the west side of Worbarrow Bay, low insu- 

 lated masses of Purbeck rocks appear on the 

 shore. In crossing this bay in a boat, a fine view 

 of the lofty chalk cliff is obtained ; and through the 

 valley in the centre of the cove, Lulworth Castle 

 forms a striking object in the distance. At a spot in 

 this bay called Arish-mel, vertical chalk and flint 

 strata, as at Handfast Point, are well displayed. 



Lulworth Cove. — The picturesque scenery of

 to tourists, and the little village of West Lulworth, 

 which is charmingly situated in a deep chalk 

 valley, was a frequent resort of water-parties from 

 Weymouth, during the summer, ere its attractions 

 were heightened by the discovery that the geology 

 of the country is in the highest degree interesting. 

 West Lulworth, of which a sketch is given in 

 PL XVIII. (p. 381), is about two miles west of
