In his attempt to divert the migration stream he was no enemy of America, (indeed he had chosen the name "Vermont" for his own farm on the Nepean) but he was perhaps the first Australian really to support Macquarie's drive for Australian expansion and Australian independence from London administration. He did this at a time when some influential Englishmen were urging the abandonment of the whole Botany Bay venture, which, after thirty years, was still not self-supporting and which seemed doomed to suffer from recurrent crises. Apparently Macquarie had dreamed of a great transcontinental river, which was to flow 2,000 miles westwards from the Dividing Range, through fertile and well-watered fields, until it reached the sea somewhere on the north-west coast. The Lachlan had been found to peter out into swamps, but Oxley believed that the Macquarie River would have a happier issue, and at the time of the first Edition of this book (1819) that theory was still tenable. It was not long, of course, before these hopes were to perish in the Macquarie Marshes, to be succeeded by prospects of a mythical Inland Sea, though it was decades before the enthusiasts realised that they would have to be satisfied with Lake Eyre. This first edition accepts as fact the phantom of that transcontinental stream and expatiates on the blessings which it would bring, patterning its concept of the Heart of the Australian Continent upon what was known of the Great Plains of America, then just being opened up. Any child with an Atlas in hand can now decry the mistake of having given to this concept more credence than did Oxley or Macquarie: does not hindsight make history so simple? Abandonment of simple optimism on this physical fact must have been quick and uncomfortable: but abandonment of some other precepts must have been slow and more painful. At the time of this first edition, the influence of the Enlightenment was completing its penetration into politics and economics. Man had only to be given freedom, and he would enter into a political Paradise: the forces of the free market had only to be left untrammelled, and they would create of themselves an economic Eden! These are the enthusiasms of the first edition, where Bligh represents the forces of repression and darkness, while Macquarie and Macarthur are both to be numbered among the angels. By the time of the third edition (1824, nearly contemporary with the author's return to Australia) the winds of change had blown through the Australian scene. Bigge had presented his Report, which destroyed so much of Macquarie's work, and the Exclusives, in the author's view, were leagued with enemies of Australian identity.
