The space to the south of this, which appeared to be a strait, insulating the land to the north as far as Cape Leveque, is nine miles wide.

The south shore trends to the westward to Cape Villaret, on which there is a remarkable hillock, in latitude 18 degrees 19 minutes 5 seconds, and longitude 122 degrees 3 minutes 45 seconds.
The space between the Cape and Point Gantheaume was called ROEBUCK BAY.
It is here that Captain Dampier landed, in the year 1688.
Three miles to the south of the hillock on Cape Villaret, are two lumps, which at a distance appeared like rocks.

Cape Latouche-Treville has a small hummock near its extremity, in latitude 18 degrees 29 minutes, and longitude 121 degrees 50 minutes 50 seconds; to the eastward of it, there is a shallow bay open to the northward.
The depth of water in the offing of Roebuck Bay, is between eight and twelve fathoms; the bottom is sandy, and there are in some parts sandbanks, on which the depth decreased three fathoms at one heave, but the least water was eight fathoms.

The flood-tide sets to the eastward, towards the opening, and at an anchorage near Cape Latouche-Treville, the ebb ran to the North-East: but the tides were at the neaps, and did not rise more than sixteen feet.

Captain Dampier, at the springs, found it flow thirty feet, which tends unquestionably to prove the opening behind Roebuck Bay to be considerable, even if it does not communicate with that behind the Buccaneer's Archipelago.
The interval between Cape Latouche-Treville and Depuch Island, was not seen by us.
