460 VABELLA AND DURIAN STRAITS. [chap. xi.
S. by E. course, or with Deepwater point bearing about S. -^ E., will lead
clear of the mud-bank that fronts Pulo Burii, and mid-way between it and
Middleburgh shoal.
In working, a vessel may stand to the eastward to a moderate distance
at discretion, but to the westward she must not approach the shore of Pulo
Btirii nearer than 1^ miles, in 5^ to 6 fathoms. When the south end of
Pulo Bdrd bears northward of West, the soundings will decrease regularly
on the edge of the mud-bank which extends southward as far as Deep-
water point, and the mud-bank may be borrowed on at discretion. Standing
eastward towards Middleb.nrgh shoal, tack when the west end of North
Passage island touches the east end of South Passage island. The north
end of Red island in line with the north extreme of Pulo Bolombo, will
lead northward of Middleburgh shoal, and the north end of Red island in
line with the south Twin, will lead southward.
When southward of Middleburgh shoal, a direct course may be steered
for the east end of False Durian ; the Passage islands may be approached
to any convenient distance, but Princes island should be given a berth of
one mile. The depths throughout are irregular, decreasing towards the
western shore where there is a good anchorage. The bank of hard sand
and stones, having 4J fathoms least water, lying north-westward of False
Durian, will be avoided by keeping the north extreme of South Brother
open of False Durian.
Standing towards the south end of Great Durian, come no nearer the
Tombs than one mile, tacking before the whole ot North Passage island is
shut in with Little Durian. The best anchorage in this part of the strait
will be found about three-quarters of a mile from the eastern shore of
False Durian, in 12'to 14 fathoms. With a working wind and a favourable
tide, keep near False Durian, where the tides are much stronger than in
taking care to bring Rocky islet to the westward of S. by W.
mid-channel ;
before the peak of False Durian bears West, to avoid Richardson shoal.
To pass Westward of the Brothers, between them and
False Dnrian, steer through in mid-channel ;
but when working and standing
to the westward, keep South Passage island open of False Durian until the
north
avoid
extreme of South Brother bears northward of E. by N. | N., to
the patches southward of False Durian. The Brothers may be
approached to a prudent distance.
To pass Eastward of the Brothers, being eastward of the
Tombs steer from one to 2 miles northward and eastward of the North
Brother, where the water will shoal to 12 or 13 fathoms; then steer about
S.S.E., attending to the set of the tide, to pass the Middle and South Brother
at the same distance, hot bon-bwihg nearer them than 10 or 12 fathoms.
With a working wind, and standing towards Eastern bank, avoid bringing
