The coast also between the North-west Cape and Depuch Island, containing two hundred and twenty miles, has also been sufficiently explored; but between the latter island and Port George the Fourth, a distance of five hundred and ten miles, it yet remains almost unknown. The land that is laid down is nothing more than an archipelago of islands fronting the mainland, the situation of which is quite uncertain. Our examinations of these islands were carried on as far as Cape Villaret, but between that and Depuch Island the coast has only been seen by the French, who merely occasionally saw small detached portions of it. At present however this is conjecture; but the space is of considerable extent and, if there is an opening into the interior of New Holland, it is in the vicinity of this part. Off the Buccaneer's Archipelago the tides are strong and rise to the height of thirty-six feet. Whatever may exist behind these islands, which we were prevented by our poverty in anchors and other circumstances from exploring, there are certainly some openings of importance; and it is not at all improbable that there may be a communication at this part with the interior for a considerable distance from the coast. The examination of the western coast was performed during an almost continued gale of wind, so that we had no opportunity of making any very careful observation upon its shores. There can however be very little more worth knowing of them, as I apprehend the difficulty of landing is too great ever to expect to gain much information; for it is only in Shark's Bay that a vessel can anchor with safety.
