Geology of Australia, at the close of which that gentleman acquainted the public with the proposal I had made to the Governor, and the sanction and support which His Excellency was disposed to give it.  The following extract is from Captain Sturt’s address, and shews the disinterested and generous zeal which that talented and successful traveller was ever ready to exert on behalf of those who were inclined to follow the career of enterprise and ambition in which he had with such distinction led the way.

“Before I conclude, however, having drawn your attention to the science of geology, I would for a moment dwell on that of geography, and the benefit the pursuit and study of it has been to mankind.  To geography we owe all our knowledge of the features of the earth’s surface, our intercourse with distant nations, and our enjoyments of numberless comforts and luxuries.  The sister sciences of geography and hydrography have enabled us to pursue our way to any quarter of the habitable and uninhabitable world.  With the history of geography, moreover, our proudest feelings are associated.  Where are there names dearer to us than those of the noble and devoted Columbus, of Sebastian Cabot, of Cook, of Humboldt, and of Belzoni and La Perouse?  Where shall we find the generous and heroic devotion of the explorers of Africa surpassed?  Of Denham, of Clapperton, of Oudeny, and of the many who have sacrificed their valuable lives to the pestilence of that climate or to the ferocity of its inhabitants?—­And where shall we look for the patient and persevering endurance of Parry, of Franklin, and of Back, in the northern regions of eternal snow?  If, ladies and gentlemen, fame were to wreathe a crown to the memory of such men, there would not be a leaf in it without a name.  The region of discovery was long open to the ambitious, but the energy and perseverance of man has now left but little to be done in that once extensive and honourable field.  The shores of every continent have been explored—­the centre of every country has been penetrated save that of Australia—­thousands of pounds have been expended in expeditions to the Poles—­but this country, round which a girdle of civilization is forming, is neglected, and its recesses, whether desert or fertile, are unsought and unexplored.  What is known of the interior is due rather to private enterprise than to public energy.  Here then there is still a field for the ambitious to tread.  Over the centre of this mighty continent there hangs a veil which the most enterprising might be proud to raise.  The path to it, I would venture to say, is full of difficulty and danger; and to him who first treads it much will be due.  I, who have been as far as any, have seen danger and difficulty thicken around me as I advanced, and I cannot but anticipate the same obstacles to the explorer, from whatever point of these extreme shores he may endeavour to force his way.  Nevertheless, gentlemen, I shall envy that man who shall first plant the flag of our native
