her by a rocky strait three
miles wide, which in most parts is deep enough for a ship of any size to
pass through; the latitude of the centre of this strait is 11 degrees 32
minutes. Macquarie Strait separates the southernmost from the main, and
is nearly two miles across: the depth in mid-channel being eighteen
fathoms: the latitude of Retaliation Point, which is on the northern side
of the strait, is in 11 degrees 39 minutes.

SOUTH WEST BAY affords good anchorage in five and six fathoms at a mile
from the shore, and vessels may anchor at a quarter of a mile off the
beach in three fathoms muddy bottom.

At the north end of the bay are the Bottle Rocks separated from the point
by a channel two and a quarter fathoms deep. The Bottle Rock was one of
our fixed points, and is placed in latitude 11 degrees 37 minutes 24
seconds, and longitude 133 degrees 19 minutes 40 seconds. The bay affords
a convenient place for wooding and watering; the latter may be had during
the early months of the dry season (as late as August) from a drain at
the base of the Pipe Clay Cliffs at the north end of the bay. There are
also some holes on Sims Island that contain water for a much later
period. The holes have been made by the Malays for the purpose of
collecting it.

MULLET BAY is on the west side of the north island, affording good
anchorage in the easterly monsoon in six and seven fathoms mud, at a mile
from the shore. The flood-tide here sets to the eastward, and it is high
water at full and change in the strait at six o'clock; the rise of the
tide is not more than five or six feet. The north-east point of North
Goulburn Island is in latitude 11 degrees 26 minutes, longitude 133
degrees 26 minutes.

From Macquarie Strait the land trends to the westward, and north-westward
to De Courcy Head, and forms but few sinuosities. POINT BROGDEN, in
latitude 11 degrees 30 minutes, the only projection in this space, is
remarkable for being higher than usual, and for having a range of cliffs
to the southward of the point; with a solitary tree near its extremity,
hence the land is rocky towards De Courcy Head, which is a cliffy
projection in latitude 11 degrees 17 minutes 30 seconds; thence the shore
continues rocky to Cape Cockburn, a low rocky point, with a conspicuous
tree at its extremity. The point is wooded to within a short distance of
the sea, as is generally the case with the shores of this coast. CAPE
COCKBURN is in latitude 11 degrees
