LIGHT.—On the west end of Terkolei stands a white lighthouse,
from which is exhibited at an elevation of 31 feet a fixed white light
visible in clear weather from a distance of 6 to 8 miles.
PULO LOBAN, lying about half a mile off the south-west part of
Beutan, is a group of four or five small islands of about 2 miles in extent,
separated by channels so narrow that they appear as one island. The two
peaks on the large island attain a height of 342 and 268 feet, and with
Pulo Loban Kechil the western islet, make from the northward as three
peaks.
A reef which is steep-to, surrounds the group, and extends in places ta
the distance of one-third of a mile. A small detached patch lies 2 cables
south of the south-west point of Pulo Loban, and a patch of 2 fathoms-
lies half a mile westward of the north point of Loban.
Isabella Shoal situated three-quarters of a mile southward of
Loban, is 7 cables long, east and west, 2 cables broad, and has from one
to 2 fathoms water. A spit with 3^ to 4 fathoms water stretches from its
eastern extreme nearly one mile in an E.S.E. direction. The depths at a
short distance from the south side of the bank are from 6 to 10 fathoms,,
but its western edge is steep, there being 1 1 fathoms close-to.
Buoys.—Black buoys in about 3 fathoms, and about 8 cables apart,
mark the east and west extremes of Isabella shoal. The western buoy
lies with Pulo Loban east peak bearing N. by W., distant If miles ; and
Terkolei lighthouse East.
Clearing markS.^Terkolei lighthouse bearing E. \ N. leads to
the southward, and Sau lighthouse in line with or open of the west end of
Loban Kechil, leads well clear to the westward of the shoal.
Dessa Islet and Keefs.—Dessa, situated on the sout&ern side of
a shoal three-quarters of a mile in extent, is a small islet, conspicuous from
having only one tree upon it, bearing N. f W. distant 2 miles from the
west end of Loban Kechil, and S. by W. \ W. about half a mile from
Tanjong Batu, the nearest point of Bentan. Two patches of reef, together
nearly a mile long, lie with their western extreme about 2 cables southward
of Dessa, and between these and the 2-fathom patch off Loban there are
depths of 4^ to 9 fathoms. A rocky patch lies 3 cables off the north-west
eide of Dessa, and the same distance off-shore. These dangers are steep-to.
Loban Kechil bearing S.S.E., or Bentan West point N. { W., leads west-
ward of thege reefs.
Pulo Dua, about three-quarters of a mile long, fronts the bay between
Batu and West points, and with the exception of a round lump which rises
in its centre is lower than the adjacent land ;
there is a remarkable white
reck near its west side. _ The island is bordered by » reef to the distance of
about 1^ cables ; two patches lie at that ^istance^ south and south-cast of
