For the next thirty miles the coast is very much indented, and has some deep bays on either side of Point Barclay, as also one to the eastward of Point Turner, at the bottom of which an opening, a mile in width, is probably a river.  Here also the feature of the coast is altered, being low and level to the eastward as far as Point Dale, without a hill or rising ground in the interior to relieve its monotonous appearance.  At this place, however, a range of rocky hills, WELLINGTON RANGE, commences, of about twenty miles in extent:  five miles behind it is the Tor (latitude 11 degrees 54 minutes, and longitude 133 degrees 10 minutes 20 seconds) a solitary pyramidal rock; and seven miles and a quarter West by South, from the latter is a peak-topped hill.

The two latter are apparently unconnected with the range, on which there are four remarkable ridges, of which the two westernmost are the most remarkable.

GOULBURN ISLANDS consist of two islands, each being about twenty miles in circumference; they are separated from each other 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.
