from that island eastward.
LekapO reef is the north-west patch of a group of isolated reefs covering

Sau reef, half 'a cable in extent with 4 fathoms water, lies 1^ miles
north-eastward of Lekapo reef, between and southward of which are
Bubara and Kotak reefs, with 2^ and 3 fathoms over them. Udyung
patches of 4f fathoms, at 3 and 3^ cables north-eastward of Sau reef,
lie in, or on the south side of Outer channel, and must be avoided by
heavy draught vessels. Here, Outer channel is but one mile wide. .
South-eastward of Sau reef shoal patches will be found for a distance of
1 J miles ; Makiam patch of 7 fathoms lies at that distance, and the ground
to the westward and between it and Middleburg island, is all foul and must
be avoided.
Buoys.—White beacon buoys mark the north edges of Lekapo and
Sau reefs, forming the south side of Outer channel.
Dapur island is a narrow islet about 260 yards in length, lying
between the northern and western approaches to Batavia road, at about 3^
miles north-eastward of Middleburg island. It is covered with bushes
amongst which stands a tall tree, and encircled by a coral reef which in
places extends nearly one cable. Tanda reef is a small coral patch with 2

The continuation of Outer channel, eastward of Sau reefs, is northward
of Dapur island and of this buoy, the channel westward of Dapur island
being named the Middle channel.
Middle grounds.—Buoys.—Outer channel, between Kombuis
islands and the Agenieten islands is divided into two branches ; the
southern one running along the north side of Kombuis island and Lekapo
and Sau reef, and the northern one running close southward of the Agenieten
islands. Between these channels isolated patches extend 4 miles in an east
and west directiop, 2 miles north and south, and may be termed the middle
grounds.
Delima reef, at the western extreme of this group, is half a cable
in extent, with a depth of 2^ fathoms, and 18 to 20 fathoms close to. A
