8. Aspect of the Country. — In tra-
versing the country between Morte-
hoe and Lee Bay, I was again struck
with the exact similarity of the form
of ground and nature of scenery to
that so frequent in the Carboniferous
Slate country of county Cork. The
general surface of the high ground is
uniform and monotonous, but it is
cut into such numerous little dells,
opening out into deeper ravines, and
these into steep-sided, flat-bottomed
valleys, that it becomes picturesque
and beautiful. The tops of the hills,
too, left standing between the ravines
and valleys, are varied by frequent
little brows and ridges of slate, form-
ing small, parallel, escarped terraces,
and rocky crags, and furze -covered
knolls, while the colour and nature
of the soil, and all the minuter fea-
tures of the scenery are identical in
both countries.
I was hastily summoned from II-
fracombe, on private business, before
I could examine the calcareous bands
and other rocks of Combe-Martin and
its neighbourhood. If, however, the
Lynton rocks below, and the Ilfra-
combe and Mortehoe rocks above be
determined, the intermediate Combe-
Martin beds follow as a matter of
course.
9. Probable Existence of a Great
East and West Fault with Downthrow
to tlie Northivard. — Having now laid
before the Society the means I have
had of examining the rocks and form-
ing an opinion upon them, I have to
state my deliberate judgment that
the rocks of Lynton, Ilfracombe, and
Mortehoe are part of the same group
of rocks as those called the Carboni-
ferous Slate in Ireland, and that the
rocks which strike from Pickwell
Down, through Swinham Down, Gar-
monds Down, Span Head (of the Ord-
nance map), and Dulverton Common,
to Haddon Down, are the upper part
