to form one of the lower beds of the division, and may be traced each way to some distance. It is succeeded by the more compact dark-coloured rock of Wallow Crag, in which quartz, calcareous spar, chlorite, and epidote, are found in veins. Garnets are found imbedded in some of the rocks on Castlerigg Fell and Great Gable. An amygdaloid rock, containing nodules of calcareous spar, and sometimes of agate, opal or calcedony, is met with in several places; as near Honister Crag - between Bowder Stone and Rosthwaite - on Castlerigg Fell near Keswick - and in Wolf Crag on the road to Matterdale. A curious mixed rock of basaltic appearance is found near Berrier; it skirts the north side of Caldbeck Fells, forms the hill called Binsey, and may be seen on the north side of the Derwent near to Cockermouth.
The fine pale-blue roofing slate occurs in beds: (called by the workmen veins:) the most natural position of the lamina or cleavage of the slate appears to be vertical: but it is to be found in various degrees of inclination, both with respect to the horizon, and the planes of stratification. The direction of the slaty cleavage bears most commonly towards the north-east and south-west; while the dip or inclination is more variable; the former may be ascribed to some general operation of nature; the latter being influenced by local circumstances - such as the weight of a mountain pressing upon one side, while the other side is wanting a support.
