SAILING DIRECTIONS.

from the main, and is nearly two miles across : the depth a. 
in mid-channel being eighteen fathoms : the latitude of Re- Sect. III, 
taliation Point, which is on the northern side of the strait, N. Coast, 
is in 11039 '. 
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 sepa- 
rated 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° 37' 24", and longitude 133° 19' 40". 
The bay affords a convenient place for wooding and water- 
ing; 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° 26', lon- 
gitude 133° 26'. 
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° 30', the only 
projection in this space, is remarkable for being higher than
