The direction and inclination of the strata are more distinguished by stripes and alternations in the colour and texture, than by any natural partings or strata seams; and the slates are split of various thickness, according to their fineness of grain, and the discretion and skill of the workman, without any previous indication of the place where they may be so divided. They do not separate into thin flakes, like those of the former division; but some of them, when long used, are subject to a peculiar species of decay, which operates most powerfully on parts least exposed to the weather.
Most of the rocks of this division effervesce in some degree with acids, but more especially those possessing the slaty structure. They are not very productive of metallic ores, although they afford a considerable variety. Lead ore has been got in Patterdale; copper at Dalehead in Newlands, which is near the northern boundary of the division - it consists of grey and purple copper, with specimens of malachite. A mine at Coniston, near the southern boundary, produces the yellow sulphuret; and a vein of the same was a few years ago opened at Wythburn. Small veins of iron ore are frequently met with, but scarcely thought worth notice. The famous plumbago or black-lead mine of Borrowdale is also situated in this division: but no organic remains have been discovered in either this or the preceding.
