The lake which has thus terminated our journey, is from fifty to sixty miles in length, and from thirty to forty in width. With such an expanse of water, I am correct in stating its medium depth at four feet. There is a large bight in it to the S.E. and a beautiful and extensive bay to the N.W. At about seven miles from the mouth of the river, its waters are brackish, and at twenty-one miles they are quite salt, whilst seals frequent the lower parts. Considering this lake to be of sufficient importance, and in anticipation that its shores will, during her reign, if not at an earlier period, be peopled by some portion of her subjects, I have called it, in well-meant loyalty, "The Lake Alexandrina." It is remarkable that the Murray has few tributaries below the Darling. It receives one, however, of considerable importance from the S.E., to which I have given the name of the "Lindesay," as a mark of respect to my commanding-officer, and in remembrance of the many acts of kindness I have received at his hands. Having dwelt particularly on the nature of the country through which the expedition has passed in the pages of my journal, it may be unnecessary for me to enter into any description of it in this place, further than to observe, that the limestone continued down to the very coast, and that although the country in the neighbourhood of the Lake Alexandrina must, from local circumstances, be rich in point of soil, the timber upon it is of stunted size, and that it appears to have suffered from drought, though not to the same extent with the eastern coast. It is evident, however, that its vicinity to high lands does not altogether exempt it from such periodical visitations; still I have no doubt that my observations upon it will convince His Excellency the Governor, that it is well worthy of a closer, and more attentive examination, than I had it in my power to make. In a geographical point of view, I am happy to believe that the result of this expedition has been conclusive; and that, combined with the late one, it has thrown much light upon the nature of the interior of the vast Island; that the decline of waters, as far as the parallel of 139 degrees E., is to the south, and that the Darling is to the N.E. as the Murray is to the S.E. angle of the coast, the main channel by which the waters of the central ranges are thrown or discharged into one great reservoir. Our journey homewards was only remarkable for its labour: in conclusion, therefore, it remains for me to add that we reached the depot on the 23rd of March. Our sugar failed us on the 18th of February, and our salt provisions, in consequence of the accident which happened to the skiff, on the 8th of March; so that from the above period we were living on a reduced ration of flour; and as we took few fish, and were generally unsuccessful with our guns, the men had seldom more than their bread to eat.
