The following account of the proceedings of the morning, taken from the South Australian Register, of the 20th June, may perhaps be read with interest; at least it will shew the disinterested spirit and enterprising character of the colonists of South Australia, even at this early stage of its history, and especially how much the members of our little party were indebted to the kindness and good feeling of the Governor and colonists, who were anxious to cheer and stimulate us under the difficulties and trails we had to encounter, by their earnest wishes and prayers for our safety and success. EXPLORATORY EXPEDITION TO THE CENTRE OF NEW HOLLAND The arrangements for the expedition into the interior, undertaken by Mr. Eyre, having been completed, His Excellency the Governor and Mrs. Gawler issued cards to a number of the principal colonists and personal friends of Mr. Eyre, to meet him at Government House on the morning of his departure. On Thursday last accordingly (the anniversary of Waterloo, in which His Excellency and the gallant 52nd bore so conspicuous a part) a very large party of ladies and gentlemen assembled. After an elegant DEJEUNER A LA FOURCHETTE, His Excellency the Governor rose and spoke as nearly as we could collect, as follows:-- "We are assembled to promote one of the most important undertakings that remain to be accomplished on the face of the globe--the discovery of the interior of Australia. As Captain Sturt in substance remarked in a recent lecture, of the five great divisions of the earth, Europe is well known; Asia and America have been generally searched out; the portion that remains to be known of Africa is generally unfavourable for Europeans, and probably unfit for colonization; but Australia, our great island continent, with a most favourable climate, still remains unpenetrated, mysterious, and unknown. Without doing injustice to the enterprising attempts of Oxley, Sturt, and Mitchell, I must remark that they were commenced from a very unfavourable point--from the eastern and almost south-eastern extremity of the island--and consequently the great interior still remains untouched by them, the south-eastern corner alone having been investigated. As Captain Sturt some years since declared, this Province is the point from which expeditions to the deep interior should set out. This principle, I know, has been acknowledged by scientific men in Europe; and it is most gratifying to see the spirit with which our Colonists on the present occasion have answered to the claim which their position imposes upon them. Mr. Eyre goes forth this day, to endeavour to plant the British flag--the flag which in the whole world has "braved for a thousand years the battle and the breeze"--on the tropic of Capricorn (as nearly as possible in 135 degrees or 136 degrees of longitude) in the very centre of our island continent. On this day twenty-five years since, commencing almost at this very hour, the British
