The foregoing narrative will have given the reader some idea of the state in which the last expedition reached the bottom of that extensive and magnificent basin which receives the waters of the Murray. The men were, indeed, so exhausted, in strength, and their provisions so much reduced by the time they gained the coast, that I doubted much, whether either would hold out to such place as we might hope for relief. Yet, reduced as the whole of us were from previous exertion, beset as our homeward path was by difficulty and danger, and involved as our eventual safety was in obscurity and doubt, I could not but deplore the necessity that obliged me to re-cross the Lake Alexandrina (as I had named it in honour of the heir apparent to the British crown), and to relinquish the examination of its western shores. We were borne over its ruffled and agitated surface with such rapidity, that I had scarcely time to view it as we passed; but, cursory as my glance was, I could not but think I was leaving behind me the fullest reward of our toil, in a country that would ultimately render our discoveries valuable, and benefit the colony for whose interests we were engaged. Hurried, I would repeat, as my view of it was, my eye never fell on a country of more promising aspect, or of more favourable position, than that which occupies the space between the lake and the ranges of St. Vincent's Gulf, and, continuing northerly from Mount Barker, stretches away, without any visible boundary. It appeared to me that, unless nature had deviated from her usual laws, this tract of country could not but be fertile, situated as it was to receive the mountain deposits on the one hand, and those of the lake upon the other. FURTHER EXAMINATION OF THE COAST. In my report to the Colonial Government, however, I did not feel myself justified in stating, to their full extent, opinions that were founded on probability and conjecture alone. But, although I was guarded in this particular, I strongly recommended a further examination of the coast, from the most eastern point of Encounter Bay, to the head St. Vincent's Gulf, to ascertain if any other than the known channel existed among the sand-hills of the former, or if, as I had every reason to hope from the great extent of water to the N.W., there was a practicable communication with the lake from the other; and I ventured to predict, that a closer survey of the interjacent country, would be attended with the most beneficial results; nor have I a doubt that the promontory of Cape Jervis would ere this have been settled, had Captain Barker lived to complete his official reports.
