the outermost of them. The whole coast, of which little is known, and the
islands off it are as a rule fringed with coral.
ISLANDS AND REEFS. -Pulo Gin or Great
Island, is the name given to three islands, which are together about
4 or 5 miles in extent, lying about 6 miles south-eastward of the south-
east extreme of Bentan, and separated from each other by narrow
channels. Several hills on the islands are from 200 to 300 feet high, and
one, named Gin peak, rising about the centre of the south-eastern island,
is 337 feet.
Pulo Terobi, the most southern of a cluster of islets, lying to the
eastward of Pulo Gin, is 112 feet high, and bears E. by S. 2^ miles from
the south-east extreme of that island.
Pulo Borean or Saddle Island, is the northern of these
islets, and bears from Pulo Terobi, N. by E. ^ E. 5 miles. Being 308 feet
high, and saddle-shaped, it is conspicuous and easily recognised.
Geldria bank is the outermost of a dangerous groups of shoals
lying 13 or 14 miles eastward of Pulo Gin, well out in the fairway of
vessels proceeding between Banka and Singapore straits, especially such
as pass inside Frederick reef. Its north extreme lies E. by N. ^ N.
distant 15 miles from Gin peak, whence it extends in a south-west
direction about 2i miles, having 2 to 4 fathoms water, 19 to 20 fathoms
close to the eastern side, and 8 to 12 fathoms, irregular depths, near the
south-west and west sides.
Raleigh. Sboal lies W. by S. § S. distant 3 miles from the south-
west extreme of the Geldria. It has 2 fathoms water over a coral bottom,
from which Pulo Borean bears W. byN. o miles. Several patches of
4 fathoms lie northward and southward of it.
A shoal patch, of coral and sand, nearly one mile in length and
half a mile in breadth, with 2 fathoms water, lies 3 miles south-westward
of Ealeigh shoal, with the centre of Pulo Borean bearing N.W. i N.
distant 4j miles.
The neighbourhood of these patches should be avoided by vessels of
heavy draught.
Boat rocks (KajU Ara), lying about^ 2^ miles north-west from
the north end of Geldria bank are three low rocks, visible about 4 miles.
A rocky patch, with 3 fathoms water, lies about midway between Geldria
bank and Boat rock.?.
Pulo Ruig or Ragged Island, appropriately named from the
irregular appearance of the trees on its summit, is the outer and eastern-
most island off the east coast of Bentan. It is 115 feet high, abopt th?
same size as Pulo Bcrean, and is steep- to at 3 cables off.
