"We are now not more than two hundred and fifteen feet above the sea, with a declining country to the north-west, and the general dip of the continent to the south-west. What is the natural inference where there is not a single river emptying itself upon the coast, but that there is an internal basin? Such a country can only be penetrated by cool calculation and determined perseverance. I have sat down before it as a besieger before a fortress, to make my approaches with the same systematic regularity. I must cut hay and send forage and water in advance, as far as I can. I have the means of taking sixteen days' water and feed for two horses and three men; and if I can throw my supplies one hundred miles in advance, I shall be able to go two hundred miles more beyond that point, at the rate of thirty miles a-day, one of us walking whilst two rode. Surely at such a distance some new feature will open to reward our efforts! My own opinion is, that an inland sea will bring us up ere long--then how shall we get the boat upon it? 'Why,' you will say, 'necessity is the mother of invention.' You will find some means or other, no doubt; and so we will. However, under any circumstances, depend upon it I will either lift up or tear down the curtain which hides the interior from us, so look out for the next accounts from me as of the most interesting kind, as solving this great problem, or shutting the door to discovery from this side the continent for ever. "P.S. Poole has just returned from the ranges. I have not time to write over again. He says that there are high ranges to N. and N.W. and water,--a sea extending along the horizon from S.W. by W., to ten E. of N. in which there are a number of islands and lofty ranges as far as the eye can reach. What is all this? Are we to be prosperous? I hope so; and I am sure you do. To-morrow we start for the ranges, and then for the waters,--the strange waters on which boat never swam, and over which flag never floated. But both shall are long. We have the heart of the interior laid open to us, and shall be off with a flowing sheet in a few days. Poole says that the sea was a deep blue, and that in the midst of it there was a conical island of great height. When will you hear from me again?" From this communication, Captain Sturt appears to be sanguine of having realized the long hoped for sea, and at last of having found a key to the centre of the continent. Most sincerely do I hope that this may be the case, and that the next accounts may more than confirm such satisfactory intelligence. My own impressions were always decidedly opposed to the idea of an inland sea, nor have I changed them in the least, now that circumstances amounting almost to proof, seem to favour that opinion.
