Yew Tree. Here it makes a considerable slip to the eastward,
after which it ranges past the Tarns upon the hills above Borwick
ground; and stretching through Skelwith, it crosses the head of
Windermere near Low Wood Inn. Then passing above Dovenest and
Skelgill, it traverses the vales of Troutbeck, Kentmere, and Long
Sleddale; crossing the two intervening mountains in the direction
of the roads which lead over them; so that no relation can be
discovered between the direction of the vallies and that of the
stratification. It dips to the south-east, while the cleavage of
the slate with which it is associated frequently inclines in an
opposite direction. After being broken and interrupted by the
granite of Wasdale Crag, a fragment appears at Shap Wells.
Towards the south-east succeeds a series of rocks of the same
dark-blue colour, and principally of a slaty structure, but
accompanied in places with a rock which breaks in all directions.
This last has supplied a great portion of the rounded stones
found in the beds of the rivers Kent and Lune; furnishing
materials for paving the streets, and repairing the roads in the
vicinity.
A rock of fine-grained sienite is observed near the foot of
Coniston Lake; and micaceous rock near the Birks, in Crosthwaite,
Westmorland, presents good specimens of a natural process by
which angular blocks can be reduced into rounded ones. The strata
seams are more distinct in this than in the preceding division;
but, like that, it is not marked by any natural partings in the
plane of cleavage. A quarry one mile from Brathay, on the road
towards Hawkshead, yields excellent flags for flooring; and they
are manufactured into tombstones with good effect, by Mr.
Webster, of Kendal, and Mr. Bromley, of Keswick. This quarry
affords a good ex-
