That part of the coast lying between the south-west corner of the continent and Fowler's Bay, in the Great Australian Bight, had been traversed prior to this time. In 1791 Captain George Vancouver, in the British ship Cape Chatham, sailed along it from Cape Leeuwin to King George's Sound, which he discovered and named. He anchored in the harbour, and remained there for a fortnight. He would have liked to pursue the discovery of this unknown country, and did sail further east, as far as the neighbourhood of Termination Island, in longitude 122 degrees 8 minutes. But, meeting with adverse winds, he abandoned the research, and resumed his voyage to north-west America across the Pacific. In 1792, Bruny Dentrecasteaux, with the French ships Recherche and Esperance, searching for tidings of the lost Laperouse, followed the line of the shore more closely than Vancouver had done, and penetrated much further eastward. His instructions, prepared by Fleurieu, had directed him to explore the whole of the southern coast of Australia; but he was short of water, and finding nothing but sand and rock, with no harbour, and no promise of a supply of what he so badly needed, he did not continue further than longitude 131 degrees 38 1/2 minutes east, about two and a half degrees east of the present border line of Western and South Australia. These navigators, with the Dutchman Pieter Nuyts, in the early part of the seventeenth century, and the Frenchman St. Alouarn, who anchored near the Leeuwin in 1772, were the only Europeans known to have been upon any part of these southern coasts before the advent of Flinders; and the extent of the voyage of Nuyts is by no means clear. Flinders, as we have seen, laid it down as a guiding principle that he would make so complete a survey of the shores visited by him as to leave little for anybody to do after him. He therefore commenced his work immediately he touched land, constructing his own charts as the ship slowly traversed the curves of the coast. The result was that many corrections and additions to the charts of Vancouver and Dentrecasteaux were made before the entirely new discoveries were commenced. In announcing this fact, Flinders, always generous in his references to good work done by his predecessors, warmly praised the charts prepared by Beautemps-Beaupre, "geographical engineer" of the Recherche. "Perhaps no chart of a coast so little known as this is, will bear a comparison with its original better than this of M. Beaupre," he said. His own charts were of course fuller and more precise, but he made no claim to superiority on this account, modestly observing that he would have been open to reproach if, after following the coast with an outline of M. Beaupre's chart before him, he had not effected improvements where circumstances did not permit so close an examination to be made in 1792.
