it disappears under tlie basalt, and continues for half a mile invisible.
It re-appears for about thirty yards on the seashore, about half way
betwixt Mr. Smith's house and the sluices. Here, where the covering
of basalt is awanting, it has been pierced by a well, and water found in
abundance.
42.—2. Love Grove Beds.—Tho extensive cutting for tlie debou
chure of the Town Drain, at the sluices near Worlee Hill, affords
a beautiful section of the trap and stratified rocks. The general
level of the island is so close on that of high water, that a canal two
miles in length required to be cut before a proper point of dis
charge could b& found for it, and here a cut thirty feet across, 1,000
in length, the continuation of the canal to seaward, and sixteen in
depth, required to be made, to enable it to secure sufficient scour
from the seru The cut traverses a little natural valley, betwixt a
hillock of basalt, part of the Love Grove ridge, and the southern end of
Worlee Hill, The stratified rock along the valley appears at the surface,
and is seen to descend at both sides under the trap, dipping to the W 0
and by S. at an angle of about 12°, in a tolerably even plain. The
upper beds are of a dirty yellowish colour for about from one to two feet
down: to this a mass of perfectly black strata, highly bituminous, suc
ceeds. It smells strongly of coal tar when fresh broken, and smokes,
loses weight, and changes colour, in the fire. It abounds in impressions
of reeds and grasses, and here also skeletons of frogs and tortoises
are to be found.f Just at the sluices the regularity of the beds has been
disturbed, and they dip for a little in all directions. Here they are
surmounted by a large mass of basalt, rising into a little hill: more
towards the sea they crop out again, the basalt disappearing,—and from
high water mark out to sea they are covered over with a mantle of
basalt broken into fragments, and from two to four feet in thickness :
and this state of matters continues till the rock disappears under the
occean. The lower beds of these strata are full of nodules and
septana, and seem to have been much disturbed in comparison to the
