Carrick-a-rede is the next remarkable headland to Kenbaan. 

 Between these promontories the chalk twice rises above the level 

 of the sea, and as often sinks beneath it ; the strata exhibiting 

 evident marks of dislocation, and either of elevation or subsi- 

 dence. 



^ Carrick-a-rede is an insulated crag of rudely prismatic basalt ; 

 the dangerous rope bridge thrown across to connect it with the 

 mainland by those engaged in the salmon fishery, has rendered 

 it celebrated. 



Beyond Carrick-a-rede the limestone again rises, is traversed by 

 some whin dykes and near Sheep island forms a cliff about 100 

 feet in height. Here a large detached basaltic rock rises close to it 

 on the beach, appearing to have been brought by subsidence to 

 the same level, and to a parallel position. The same remark may 

 he extended to. Sheep island, itself a basaltic mass. 



Above these cliffs are seen the lofty basaltic hills of Knocksoghey 

 and Croaghmore, where are the columnar strata mentioned in page 

 183 ; the wood coal described in page 188 also occurs in this 

 neighbourhood, close to the village of Ballintoy, of v/hich the 

 spirg i^ seen forming a conspicuous land mark. 



The chalk suffers a partial interruption, attended as usual with 

 dislocation of the strata, near Ballintoy, but again rises to consi- 

 derable height on the sloping ground which skirts White Park bay. 

 In a valley near Ballintoy, the inferior limit of the chalk is ex- 

 posed, and a substratum of a bluish slate clay, containing gry- 

 phites and ammonites, (apparently the same which alternates with 

 the lias near Glenarm) is laid open. The chalk is abruptly broken 

 off on the east of White Park bay, in a little cove called Port 

 Braddin. Here the basalt abuts directly against the chalk, and 

 that arrangement of strata, so well known as constituting the mag-
