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 
Deep 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 be traced the courses of 
Halley’s Mount and Alarm Bidge, 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 
Bidge. 
The features we shall next notice are the effects produced by a 
slight upheaval, which some subterranean force, volcanic or elec- 
trical, or both, has caused. This force, though doubtless consider- 
able 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 he 
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 
at the Barn Bock 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 tlie 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.
