and about 4 cables distant. The depths decrease suddenly from 7 to 3
fathoms towards Pulo Bokok, but more regularly towards the shoals on the
opposite side of the bay^
Sikwang point and Tanjong Pengair are, respectively,
the north-west and north-east extremes of a peninsula which projects from
about the nilddle of the north coast of Battam, separating Battam and
Bulaiig bays. The land in the vicinity consists of moderately elevated
hills, and the coast line is fringed with coral extending one or 2 cables off,
near the edge of which are irregular depths, of from 6 to 11 fathoms.
BULANG BAY, situated about 2 miles eastward of Battam bay,
is 2f miles wide between Tanjong Pengair and Tanjong Pekapu, and 2^
miles deep, narrowing towards its headj into which fall the rivers Tring
and Belie-an. The shores of the bay are fronted by reefs which extend
barely a quarter of a mile from the entrance points, but more than double
that distance within them ; and from a point a mile south-eastward of
Tanjong Pengair, a coral spit, with 15 feet over it, projects in an E. f N".
direction nearly one mile.
A small detached reef, part of which dries 3. feet, lies at the entrance of
Bulang bay, with its outer edge E. ^ N". one mile from Tanjong Pengair.
Eastward of this reef the depths are 3f and 4 fathoms for about one mile,
and then 5 and 6 fathoms towards Tanjong Pekapu. Outside the line of the
heads the depths are 8 to 11 fathoms, increasing suddenly to 23 fathoms ;
and between the reef and Tanjong Pengair the depths are 4 to 8 fathoms.
Ancborage.—The best anchorage in this bay for vessels of moderate
draught is in about 6 fathoms, with Pulo Nongsa bearing N.E. ^ E., and
the hill over Tanjong Pekapu, East. Small vessels may, with proper
attention to the lead and a good look-out, go farther in.
Eastward of Tanjong Pekapu, the coast is fronted by a coral flat ex-
tending nearly a third of a mile from the shore.
Pulo Nongsa, a small island one-third of a mile in extent with a
high tree upon it, lies about a mile to the northward of Tanjong Pekapu, and
nearly three-quarters of a mile off Tanjong Batu Bla, the nearest point of
Pulo Battam. This island is surrounded by a reef, extending about a
quarter of a mile off, between which and the shore reef is a narrow channel
having depths of 5 to 13 fathoms.
Pul^Nongsa is rather a conspicuous object when near this part of the
strait, and if kept open of Tanjong Bulang will lead a vessel clear of
Little Pan reef.
Rosa rock, nearly one mile E. by N. from Pulo Nongsa, and 2 cables
northward of the shore reef extending from Tanjong Bulang, dries at low
water, with 10 to 12 fathoms close to its north side.
