ACCOUNT OF THE 
fragments, larger than the huts of Shetland, strew tde 
shore. Among the cliffs of this shore may be seen some 
beautiful specimens of carious sandstonej produced by the 
action of the weather^ the cells of great depth, and th0 
septa of the most delicate thinnesSc 
In descending from the Snuke ridge to the platform at 
the foot of Combe Hill^ the sandstone then becomes more 
compact ; and the small scales of mica^ heretofore promiscu- 
ously arranged, are now disposed with thin, Astt surfaces 
parallel to the stratification, and more or less in layers, giv- 
ing the rock often a decided schistose characterj when the 
mica is abundant,— an appearance which may also be dis- 
covered by weathering, even where the mica is scanty. As 
we continue to descend towards the north, the sandstone 
becomes still more compact, and often passes into^ or alter- 
nates with, quartz rock, from which, however, th^ mica 
Is rarely absent, though in some of the harder varieties 
it becomes again irregularly dispersed through it. At the 
north point of the island, opposite the Friar Rocks, we 
arrive at the lowest point in the regular stratification 
of the sandstone, proceeding from the Snuke ridge. In 
a small bay (marked y in the map), the sandstone is 
much undulated, and even contorted ; the seams of stra- 
tification become wedge ^ shaped^ curved^ and leave the 
structure of the rock in an undefinable and un strati- 
fied mass* To the east and west of this point the strata 
again become remarkably straight, and their slaty struc- 
ture well marked, differing in direction, however, on 
the opposite sides of the unstratified mass; that on the 
east side bearing 77° W. of N., while, on the west side, 
the direction of the strata is 105° W. of N. The Arched 
Friar, a singularly picturesque rock, arched in two op- 
posite directions, and supported on four columns, I gob-^
