326 BANKA STRAIT. [chap. vi.
get hold of the bank extending from the Sumatra coast, and then proceed
along its edge in 8 to 6 fathoms, carefully attending to the lead. Some-
times Monopin hill will be seen, but no other land, and in such case it will
be prudent to proceed as before, keeping along the edge of the bank. .,,
With Monopin hill bearing S.E. ^ E., a vessel will be about 7 miles, and
with it bearing S.E. by E., about Similes northward of Frederick Henry
rocks, and can pass westward' of them as before directed. When Monopin
till bears about East, she will be 2 miles southward of the rocks, and may
steer S.E., for about 11 or 12 miles, tUl Monopin hill is in line with
the lighthouse on Tanjong Kalian N.E. by N. From this position it
'will be only necessary to reverse the order of the directions given at
page 323.
Working through Banka Strait from the Northward.—The
passage westward of Frederick Henry rocks is much to be
preferred when the land is obscured and reliable bearings cannot be
obtained. By reversing the' directions given at page 234 for working
through from the southward no difficulty will be experienced.
Vessels should keep towards the Sumatra coast until past Fourth point,
which they should not approach nearer than 3 miles, and remembering
that the shore bank for a distance of 6 miles westward of the point,
is almost steep-to. When Tanjong Tadah bears N.E. J N., they
may cross over to the Banka side, taking care not to bring that
point to the eastward of the above bearing. From Tanjong Tadah to
-Nangka islands they may stand inshore guided by the lead -^ but having
arrived abreast of the latter, take care not to bring West reef rock
to the westward of North, until the peak of Great Nangka island
bears N.E., and not approach the spiti off the south end of the island
under 7 fathoms. From 2| miles south of Nangka islands the shore
may be approached by the lead to any convenient depth of water, but
when Brani peak bears E.N.E. the vessel will be nearing Timbaga rocks,
and must not then come under 10 fathoms. Lalarie point bearing S.E. ^ S.
clears all the dangers near Timbaga rocks, and the point should not be
brought to the southward of that bearing, until Casuarina point bears
East. Thence to Lalarie point the shore may be again approached by the
lead J but when nearing the point the soundings decrease more suddenly,
and a vessel should not go into a less depth than 10 fathoms, and should
round the point at the distance of about 1^ miles. Thence she can pro-
ceed to the southward through either Stanton or Lucipara channels,
according to the directions given at pages 320 and 322.
