It now remains for me to submit my final "Report," or, in other words, to point out how the geographical knowledge thus acquired may be available for the economical extension of that colonisation which the expansive energies of this great nation seem to require. New South Wales may be benefited, it is true, by the establishment of any additional market on the eastern coast, for her produce; and by a road to the Gulf of Carpentaria; but a timely knowledge of the structure of the interior was necessary to enable the Government to determine on the sites most eligible for centres of colonisation required along the coast. It is now ascertained that a great range separates the coast settlements from the open pastoral country of the interior, as far as the parallel of 25 deg. south. That there it breaks off at the lofty plateau of Buckland's Table Land, which overlooks a much lower country in the north;--a country but lightly wooded, watered by good rivers, and which affords an easy access to extensive pastoral regions in the interior, without the intervention of any such formidable barrier between that interior open country and the coast, as the great range nearer the actual colony. Precisely on that part of the coast, to which the united channels of the water lead, a harbour has been surveyed and approved of by competent naval officers. These geographical facts, therefore, render it easy to define one situation more favourable than any other that might be found along that coast, for the nucleus of a colony, and which would divide almost equally the whole coast line between Sydney and Cape York. I allude to Port Bowen, near Broad Sound; and the river Nogoa, which has been (I believe) called lower down, the Mackenzie. A port on that part of the coast, at the entrance within the reefs, would be advantageous to steam navigation. The occupation of the fine country on the rivers Victoria, Salvator and Claude, must depend on some such sea-port for supplies; and on the occupation of that back-country must again, in a great measure, depend the establishment of a direct line of communication between Sydney and the Gulf of Carpentaria.
