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. The following brief description of it is taken from M. De Freycinet's account of Commodore Baudin's voyage. LAGRANGE BAY, to the east of Cape Bossut, is a bight, the bottom of which was not seen. CAPE BOSSUT is low and sandy, as well as the neighbouring land; and, with the exception of a small grove of trees a little to the north of Cape Duhamel, the country is sterile everywhere. The CASUARINA REEF is a bank of sand and rocks, parts of which are dry, on which the sea occasionally breaks. The channel between it and the shore is narrow and shoal, the depth being two and a half fathoms. The dry part of the reef extends from east to west for about two miles. Between CAPES DUHAMEL and MISSIESSY, the coast is sandy and sterile, with rocky projections: GEOFFROY and DESAULT BAYS are of the same character. With the exception of two intervals, one of which is to the west of Cape Missiessy, and the other to the east of the Bancs des Planaires, the French saw the coast between Capes Missiessy and Keraudren, but at a great distance. It appeared low and sterile. The BANCS DES PLANAIRES appeared to have a considerable longitudinal extent; it was not ascertained whether they joined the mainland: some parts seemed to be dry at low water. There is a bank with only fourteen feet water over it, situated nearly North-East from Cape Keraudren in 19 degrees 41 minutes latitude. North, a little westerly, from CAPE LARREY, between which and Cape Keraudren there is a bay with an island (POISSONNIER) in the entrance, is BEDOUT ISLAND. It is in latitude 19 degrees 29 minutes, longitude 116 degrees 32 minutes, East of Paris, or 118 degrees 52 minutes East of Greenwich. It is low and sandy. The BANC DES AMPHINOMES is very extensive, and appeared to be connected with the main; it is composed of coral, rocks, and sand.
