Valley Bay. In this second direction the flow appears still to form
the side of the crater for about a quarter of a mile down from the
top of the Peak, indeed, until it reaches Cuckold’s Point, where it
separates into two streams, one running south-easterly down to
Beep Valley, the other south-westerly, overlying and destroying
the edge of the crater, and then winding down to Green Hill and
White Hill. In a similar manner may he traced the courses of
Hailey’s Mount and Alarm Eidge, Casons and Merryman’s Hill,
with several others, as one travels westward towards High Peak,
from whence also a lava stream takes its course north-westerly towards
Horse Pasture, with an adjacent arm to the westward. A little
distance eastward of West Lodge is seen another, forming a narrow
low hill between Horse Pasture and High Hill. The next is plainly
traced as High Hill itself, and then westward, in succession,
come Bottleys, Man and Horse, Churchyard, and Devil’s Hole
Eidge.
The features we shall next notice are the effects produced by a
slight upheaval, which some subterranean force, volcanic or electrical,
or both, has caused. This force, though doubtless considerable
in itself, has in its results been moderate. It has acted
vertically throughout an imaginary line drawn from the crater-
iform hollow of Turk’s Cap Bay on the north-east, to the similarly
formed hollow at Manatee Bay on the south-west, across the
northern part of the Island, and slightly tilted more seawards
that portion which lies on its outer side. Inasmuch as it would be
impossible to walk, because of its intersecting nearly at right
angles the deep and rugged water-cut ravines with ridges and
plateaux separating them, let us glance, along this line commencing
a t the Barn Eock on the eastern corner of the Island. Here,
between it and Flagstaff Hill, we see a strange upheaval of the
unstratified cinereous sub-base of the Island* protruding high out of
the sea, and causing the lava strata which overlie it to dip eastward
and westward at angles of 35° and 20°. As might be expected,
small dikes abound at this spot, traversing in a vertical direction both
* From the Barn to the King and Queen or Prosperous Bay Telegraph, this formation,
which consists of cinereous rocks of a yellowish reddish hue, intersected in all directions by
numerous small dikes, may be seen underlying the lava strata similar to the formation on the
face of Ladder Hill, &c.
