CHAP. VII.] STOLZE CHANNEL. 353
Tierutiup bay affords no safe anchorage in the north-west monsoon, and
even during the north-east monsoon there are occasional heavy gales from
the north-west. It is advisable to moor, as variable currents in the
anchorage are liable to cause a foul anchor.
Directions.—To enter this bay, having passed the west point of
Mendauao at a distance of 2 miles, steer North or N. by E. till Rotterdam
island bears S.S.E., then steer E.N.E. till Kalmao island bears S.E. byE.^B.;
thence direct for that island until the west extreme of Kalmanbaug bears
S.W. by S., and anchor in about 7 fathoms.
When near the north-west point of Batu Binding island, in the S.E.
monsoon period, the wind will sometimes shift to the eastward ; in which
case, if bound to this bay it is better to anchor and wait for the sea breeze
from the southward or south-westward, as the current runs to the north-
west with an easterly wind.
TANJONG BIENGtA is a high bluff point, forming the northwestern
extreme of Billiton ; from this point the coast trends north-
eastward.
ArgO SllOail, about one mile in extent, with one foot water over the
middle of it, lies 4 miles northward from Karang Bakka ; from its centre,
Tanjong Bienga bears N.E. | E. ; and Tanjong Kubu, on which ai'e some
high trees, S.S.E. ^ E.
Several patches lie near Argo shoal.
ELEVEN ISLANDS are a cluster of small islands lying off the
norlh-western extreme of Billiton. The names of some of them are
Lutong (Sailors Hat), Bambu, Sampit, and Burong; the latter is the
largest of the group, and lies 3 miles north-eastward of Tanjong Bienga,
at one mile off shore.
Laugwas (North-"West) Island is the westernmost of the
Eleven islands, and lies 2J miles off shore.
Eor the description of the coast eastward of the Eleven islands, see
pages 374-5.
LIGHT. — From a lighthouse 215 feet high, painted white, on
Langwas island, is exhibited at an elevation of 200 feet above high water,
an intermittent white light. The light is fixed for sixty seconds, eclipsed
twenty-Jive seconds,flash for ten seconds, eclipsed twenty-Jive seconds ; the
whole occupying two minutes. It is visible seaward between the bearings
of North and W. ^ S. (except where obscured by islands) from a distance
of 20 miles.
Alwina shoal (originally reported by the ship Alwina in 1858), ia
a patch of 3 fathoms or less, with 15 to 16 fathoms close-to, and lies with
Langwas lighthouse bearing S.S.W., distant 1^ miles.
