[re]-opened, and is now being worked. A little cobalt ore has
formerly been got in Newlands, and this mineral is, at the
present time, undergoing extensive operations. Small portions of
manganese have been met with in various places. A salt spring,
near the Grange, in Borrowdale, has anciently been in some repute
for its medicinal qualities; another has been more recently
discovered in working a lead mine near Derwent Lake. They both
issue from veins in this rock, but their source remains unknown.
The SECOND division, or middle division, comprehends the
mountains of Eskdale, Wasdale, Ennerdale, Borrowdale, Langdale,
Grasmere, Patterdale, Martindale, Mardale, and some adjacent
places; including the two highest mountains of the district,
Scawfell and Helvellyn, as well as the Old Man at Coniston. All
our fine towering crags belong to it; and most of the cascades
among the lakes fall over it. There are indeed some lofty
precipices in the former division; but, owing to the shivery and
crumbling nature of the rock, they present none of the bold
colossal features which are exhibited in this.
Most of these rocks are of a bluish-grey colour, combining the
igneous formation with aqueous deposit, some are porphyritic,
others of a slaty structure. A reddish aggregated, or, according
to Professor Sedgwick, brecciated rock with a base of coarse
slate, is seen on entering the upon Barrow common, a
mile-and-a-half from Keswick, on the road to Borrowdale; it
appears to form one of the lower beds of the division, and may be
traced each way to some distance. It is succeeded by the compact
dark-coloured rock of Wallow Crag, in which quartz, calcareous
spar, chlorite, and epidote, are found in veins.
