288 BATAVIA BAT AND ROAD. [chap. v.
On approaching Struisvogel rocks, as directed for Inner channel, the
white buoy marking the northern rock must be left to the southward ; here
the channel between it and Hoorn islands is 5 miles wide^ with a depth
of about 30 fathoms, mud, which becomes mixed with sand towards
the islands and rocks. If approaching Outer channel from northward of
Babi island, Payung island must be kept well open southward of Hoorn
islands, to avoid Karbou rock and the foul ground westward of those
islands. From a position one mile north of Struisvogel buoy, the course
is parallel to Inner channel, or E. by S. ^ S., (taking care to avoid Laut
rock of 3J fathoms, which is steep-to, by keeping Little Kombuis open
northward of Great Kombuis), passing about 1^ miles northward of Great
Kombuis, where the depth is about 15 fathoms, and southward of Tandul
reef black buoy. From close southward of Tandul buoy, the red buoy on
Menjambang may be steered for, passing about 2 cables southward of it,
this course avoids the patches of 4^ fathoms lying in the fairway; or,
taking the south side of the channel, pass half a mile northward of Lekapo
and Sau reef white buoys, keeping (when abreast the latter) Great Kombuis
light, or the north side of that island, bearing about W. f S. astern. This
bearing will lead northward of the white buoy lying north-eastward of
Dapur island.
Vessels of deep draught wishing to avoid the 4^ fathom patches in this
fairway, should take the branch of the outer channel, one mile in width in
its narrowest part, which leads close southward of Agenieten islands reef,
(always visible by the discolouration of the water,) and northward of the
Middle grounds, the latter marked on their north side by Delima reef, and
Panjang di Laut buoys. When eastward of the buoys shape course to
pass northward of Dapur island shoals as before. From one mile north-
eastward of Dapur island steer about S.E., passing westward of Enkhuizen
island if bound to Batavia road, and eastward of it if going to the
harbour, giving the island a berth of half a mile ; thence to the road, the
course lies between Rynlaud and Pipa reef buoys; and to the harbour,
eastward of Leiden island. Vessels may pass southward of Dapur island,
and between Haarlem and Rotterdam islands, the dangers in which are
marked by buoys, for which the mariner is referred to the chart. This is
known as the Middle channel.
At nigllt.'—It does not appear advisible to attempt the navigation of
the Inner channel at night, without local knowledge. The following
directions are for Outer channel, and must be used with caution :
Great Kombuis island light must be approached bearing S.E. by E.,
which leads northward of Struisvogel rocks, and when the water shoals
to 15 fathoms, course should be altered to E. by S., passing within one
mile of the island ; when the light bears W. | S., bring it astern, which
