24 MALACCA STRAIT.— SUMATRA COAST. [ciiaim.
RaJRh. river, lO miles south-eastward of Ujong Prauhilah, has an
entrance 2^ cables wide, with a depth of 4 feet on the bar at low water
and 22 feet inside.*
LANESA BAY.—The coast to the southward of Ujong Prauhilah,
as far as Eajah river, is safe to approach to a depth of ."i fathoms at a
distance of 1^ miles from the shore ; thence to Ujong Prolin or Byan,
the north-Avest point of Lanksa bay, vessels should not shoal less than
16 or 20 fathoms, as reefs, on which the sea breaks heavily, project from
Ujong Prolin a distance of 4 miles to the northward and eastward.
Prolin point is low, but can be distinguished when bearing southward of
S.W. by S. The eastern part of the reef should not be approached nearer
than depths of 19 fathoms.
Lanksa bay is formed between Ujong Prolin on the north-west side and
Ujong Lanksa on the south-east ; the distance between these points is
4^ miles, and the depth of the bay is also about 4| miles. The bay con-
tains numerous shoals, between which there are narrow boat channels
leading into the various rivers that discharge into it. Near Ujong Lanksa,
but separated by a channel 300 yards wide and 5 fathoms deep, lies Pulo
Laga Toju, a small island about a mile in extent, and having a reef which
extends three-quarters of a mile to the northward and eastward. This
island can only be distinguished from the mainland in coming from the
south-east.
The entrance to Lanksa river lies southward of Pulo Laga Toju ; there
is a narrow channel on the north-west side of that island, but the best
channel to the river is south of Pulo Laga Toju and has 9 feet least
water. These channels, however, are only practicable for vessels of small
draught, and, as there are no leading marks, boats should be kept ahead
fiouuding. In the entrance of the river lies Pulo Rawa, an island about
half a mile in extent, westward of which the river is only 300 or 400
yards wide. The town is about 12J miles from the entrance of the river
the inhabitants cultivate rice, pepper, and rattans.
A vessel intending to send her boats to Lanksa should anchor in 9
or 10 fathoms water, with Ujong Lanska bearing S.W. by W. distant
2^ miles.
Pulo Roquit.—Prom Ujong Lanksa the coast trends east south-eastward
15 miles to Ujong Tamian ; midway there is an island named Pulo
Rokit, which is safe to approach on the north-eastern side to depths
of 10 or 12 fathoms. Between Pulo Eokit and Ujong Lanksa the shore
is skirted by a bank, which extends from one to 2 miles off shore, with
from 12 to 18 feet on its eJge ; the S9undiugs decrease very gradually
