138 SINGAPORE STRAIT. EASTERN PART. [chap. ii.
North. Rock, very small and barren, lies N. f E. nearly a mile from
North island.
Shoals.—^A shoal of 2f fathoms, the existence of which is doubtful, is
reported to lie with the large Eamunia island bearing JST.N.E. IJ miles.
A patch of 4| fathoms lies one-third of a mile in a south-easterly direction
from this position.
Clearing mark.—There is a depth of 9 to 14 fathoms close to these
dangers. Tanjong Stapah in line with South point bearing West, will
lead clear to the southward of all the dangers near Eamunia islands.
A Rock awash lies with South island bearing N.E., one-third of a
mile, .ind the large Ramunia island N. by W. about the same distance.
A three-fathom patch lies E.S.E. nearly half a mile from the rock
awash.
Stork Reef, lying N.E. by E. i E. half a mile from the threefathom
patch,' is about 3 cables in e^xtent, and from its south-west point
Barbukit hill is in line with the north hump of the large Ramunia island,
distant a little more than half a mile.
CongaltOU Skar, a rocky patch with 9 feet water, and 8 to
12 fathoms close to, is the easternmost of the dangers lying near Ramunia
slands. From it the middle of Large Lsland is in line with Peak rock, the
atter distant one mile.
Large island, W. :^ N., leads southward, and Tanjong Pungi, N.N.W. ^ "W,
leads eastward of the Skar.
Caution.—When the tide is running to the westward, vessels passine
through North channel must be very careful that they are not set too near
this danger, of which the lead will not give timely warning.
A rock awash lies a short distance E.N.E., and a 4-fathom patch
about a quarter of a mile N.N.E. from Peak rock. Another 4-fathom
patch, with 12 fathoms near it, lies a short distance to the northward of
Whale rock.
Whale Rock, lying nearly nearly three-quarters of a mile N.E.
from Peak rock, is a small ledge which is particularly dangerous, as it is
only at about three-quarters ebb that a small rock becomes visible and
indicates the existence of the danger. It is steep-to, and the depths in its
vicinity are irregular, varying from 1 5 to 9 fathoms.
Jones Reef, having 6 feet water, and 8 or 9 fathoms close to, lies
N. by W. I W. a little over half a mile from Congalton Skar.
.A Reef, about half a mile in extent, and with rocks above water, lies
between North island and North i"ock. Its eastern extreme lies North from
Peak rock nearly one mile ; and its western extreme rather less than half a
mile S. by W. from North rock. There are several patches between it
and North island.
