D. Mackintosh — Drifts of the Borders of the Lake-district. 255 



shaped mouth of Eskdale there are 

 many fine cliffs, and slopes strewn 

 with large cubical blocks of granite, 

 which would furnish a future ice- 

 laden sea with great cargoes of 

 boulders for transportation in a 

 southerly direction. 



Drifts hetween Blackcombe and the 

 Sea. — From the mouth of Eskdale, 

 a stream of mixed drift, with large 

 granite boulders, runs southwards 

 over the country between the moun- 

 tains and the sea. Much pebbly 

 gravel and sand covers the longi- 

 tudinal depression between Black- 

 combe and the higher ground border- 

 ing the sea. It rises here and there 

 into knolls separated by swamp and 

 peat basins, and in some places is 

 covered by, or alternates with, 

 Boulder-clay. Nine out of ten of 

 the large boulders on many parts 

 of the west slope of Blackcombe (on 

 the surface or imbedded in drift) 

 are Eskdale granite or granilite, and 

 Wastdale granilite. A beach of drift, 

 with a foundation of pinel in some 

 places, runs along the base, and rises 

 up to 500 or 600 feet on the side of 

 Blackcombe. North of "Whitbeck 

 this beach consists of well-rounded 

 gravel and sand, which, in one flat- 

 topped knoll, must be 120 feet thick. 

 There are other abrupt sand and 

 gravel eskers farther north. Many 

 boulders of Eskdale granite choke 

 up the mouth of Holebeck guUey, 

 where they have been mixed with the 

 granilite in situ discovered by Mr. 

 Marshall, of Leeds. 



Mr. Eccleston, of Carlisle, some 

 _ time ago discovered a stream, or 

 rather a series of groups, of granite 

 blocks, running from the fells on the 

 east side of Eskdale along the ridges 

 and slopes as far as the southern ex- 

 tremity of Blackcombe, and reaching 

 a height of at least 1000 feet above 

 the sea.^ 



^ I afterwards saw two of these ice-floe loads, the principal one being on a plateau, 



Boulder-scar.
