nearer than 6 miles. Ayer Lantju lighthouse bearing S. ^ E. will clear the
rocks, extending westward of Langgir island ; and bearing S.S.E. will clear
the reef surrounding Hoog island.
Between Ayer Lantju and Pulo Ayam the lighthouse should be kept eastward
of North ; after passing Pulo Ayam the lighthouse maybe brough
as far to the westward as N. f W., until Gresik island bears West, south-
ward of which the lighthouse must be again kept bearing eastward of
North, to clear Lima island and reefs. Ross island N.N.W. J W., or
Gunong Bolo bearing S.E. by E., leads clear of Njela bank.
To avoid Tiga shoal do not bring White rock southward of E.S.E. after
the north point of Pulo Selio bears northward of E. by N. ^ N. White rock
should be passed about a mile off, and afterwards not brought westward of
North, to avoid the edge of the bank lying south-eastward from it. Gunong
Bolo bearing N. by E. leads westward of Three-feet shoal ; and bearing
N.N.W. leads westward of Cooper shoals, Anvang bank, and Naga reef.
To avoid Carnbee rocks, Blantu hill must not be brought northward of
N. by E.
Standing to the Westward, when abreast of Hewitt shoal, do
not shut in the summit of Ayer island with the east point of Klemar
island ; abreast Klemar island, Gresik island must not be brought east-
ward of S.S.E. to avoid the rock off it. Gresik island should not be
approached within one mile, and when Klambau island bears W. ^ S., a
vessel will be southward of the dangers extending from Ayer island ; after
which she may stand to the westward until the summit of Ayer island,
bears N.N.E.
Hancock island bearing South leads eastward of Bliss shoal, but Han-
cock and Shoal-water islands must en no account be approached nearer
than 2^ miles, the lead giving very little warning in this locality. When
southward of the dangers surrounding Shoal-water island, that island
kept bearing westward of North will lead eastward of all the dangers
southward of it ; the lead, also, will give warning, as the 10-fathoms edge,
of the bank is 4 or 5 miles to the eastward of them.
