"SIR,--By the return of the WATERWITCH, I have the honour to furnish you, for the information of His Excellency the Governor, with a brief account of our proceedings up to the present date. "Upon the return of Mr. Scott from Adelaide to Port Lincoln, I left the latter place on the 24th October, following my former line of route along the coast to Streaky Bay, and rejoining my party there on the 3rd November. "The WATERWITCH had already arrived with the stores sent for the use of the expedition, and I have since detained her to co-operate with my party, in accordance with the kind permission of his Excellency the Governor. "From previous experience, I was aware, that after leaving Streaky Bay, we should have obstacles of no ordinary kind to contend with; and as I advanced, I found the difficulties of the undertaking even greater than I had anticipated; the heavy sandy nature of the country, its arid character, the scarcity of grass, and the very dense brushes through which we had frequently to clear a road with our axes, formed impediments of no trifling description, and such as, when combined with the very unfavourable season of the year, we could hardly have overcome without the assistance of the WATERWITCH. By putting on board the cutter the greater part of our dead weight, we relieved our jaded horses from loads they could no longer draw; and by obtaining from her occasional supplies of water at such points of the coast as we could procure none on shore, we were enabled to reach Fowler's Bay on the 22nd November. "From this point I could no longer avail myself of the valuable services of the cutter, the wild unprotected character of the coast extending around the Great Australian Bight, rendering it too dangerous for a vessel to attempt to approach so fearful a shore, and where there is no harbour or shelter of any kind to make for in case of need. "Under these circumstances, I left my party in camp behind Point Fowler, whilst I proceeded myself, accompanied by a native boy, to examine the country a-head, and I now only detained the WATERWITCH, in the hopes that by penetrating on horseback beyond the head of the Great Bight, I might be able to give his Excellency some idea of our future prospects. "For the last twenty-four days I have been engaged in attempting to round the head of the Bight; but so difficult is the country, that I have not as yet been able to accomplish it. In my first essay I was driven back by the want of water and obliged to abandon one of my horses. This animal I subsequently recovered.
