extensive openings, which may be the mouths of other rivers, but were left unexamined.
“The succeeding portion of coast, extending to the meridian of 117° E. is contained in the next sheet. It is mostly taken from the survey made by Captain Baudin in the French expedition to these parts, and this was only seen by them at a distance. The coast between Forestier’s Islands and Cape Latouche Treville, an extent of about 250 miles, is laid down in this manner.
“The coast between Forestier’s Islands and Cape Cuvier is better defined on the last sheet of the north-west coast. Dampier’s Archipelago in 117° E. longitude, as well as Exmouth Gulf, at the north-west extremity of the continent, are given on an extended scale in separate charts. The former of these was named by M. Baudin, Rosemary Island, being generally supposed to be that on which Dampier landed. The eastern coast of Exmouth Gulf still remains to be examined.
“The whole western coast of the continent is contained in one sheet, and is the last of Captain King’s charts of Australia. Although on a very limited scale, the nature of the coast generally is not such as to require it much larger, if we except Shark’s Bay, the adjacent harbours, and Swan River, of which places we should have been glad of particular plans. A misplaced reliance on the surveys of the French, induced Captain King to leave these places, and it is no less remarkable than true, that although we have of late established a colony at the entrance of Swan River, we do not possess a plan of it which can be depended on as accurate; and although we know something of the localities of Cockburn Sound, our chart of it is far from being complete. The deficiency has been in some degree made up by a plan of the entrance to this Sound, published at the Admiralty, from a survey by Lieutenant Roe, the surveyor-general of the colony, to whom we have before alluded. It is intended principally to show the entrances to the Sound, between Carnac Island (formerly Isle Berthoullet) and Buache Island. So far it is sufficient for navigation, but requires many soundings, as well as the approaches to Swan River, to complete it. We sincerely hope, that for the benefit of navigators, as well as for the new settlement, that this will be shortly followed by a chart of the southern half of the Sound, and a good plan of Swan River.
“A survey of the entrances of Macquarie Harbour in Van Diemen’s Land, by Captain King, remains yet to be noticed, as well as an elaborate and very useful plan of Port Jackson, by Lieutenant Roe. The former of these two presents an intricate channel into a spacious harbour, the channel being rendered narrow and dilHcult to navigate, by extensive flats of sand projecting from each shore. That of Port Jackson, by Lieutenant Roe, contains all the various branches of this noble harbour, and extends up to Paramatta.
“The above surveys are accompanied by some elaborate and very useful
