We had approached to within twelve miles of the ranges, but had not gained their southern extremity. From the camp, Mount Barker bore nearly north. The ranges appeared to run north and south to our position, and then to bend away to the S.S.W., gradually declining to that point, which I doubted not terminated in Cape Jervis. The natives kept aloof during the night, nor did the dogs by a single growl intimate that any had ventured to approach us. The sound of the surf came gratefully to our ears, for it told us we were near the goal for which we had so anxiously pushed, and we all of us promised ourselves a view of the boundless ocean on the morrow. CHANNEL TO THE SEA--ITS SHALLOWNESS. As the morning dawned, we saw that the natives had thrown an out-post of sixteen men across the channel, who were watching our motions; but none showed themselves on the hills behind us, or on any part of the south shore. We embarked as soon as we had breakfasted, A fresh breeze was blowing from the N.E. which took us rapidly down the channel, and our prospects appeared to be as cheering as the day, for just as we were about to push from the shore, a seal rose close to the boat, which we all regarded as a favourable omen. We were, however, shortly stopped by shoals; it was in vain that we beat across the channel from one side to the other; it was a continued shoal, and the deepest water appeared to be under the left bank. The tide, however, had fallen, and exposed broad flats, over which it was hopeless, under existing circumstances, to haul the boat. We again landed on the south side of the channel, patiently to await the high water. M'Leay, myself, and Fraser, ascended the hills, and went to the opposite side to ascertain the course of the channel, for immediately above us it turned south round the hills. We there found that we were on a narrow tongue of land. The channel was immediately below us, and continued to the E.S.E. as far as we could trace it. The hills we were upon, were the sandy hills that always bound a coast that is low, and were covered with banksias, casuarina and the grass-tree. To the south of the channel there was a flat, backed by a range of sand-hummocks, that were covered with low shrubs; and beyond them the sea was distinctly visible. We could not have been more than two and a half miles from the beach where we stood. Notwithstanding the sandy nature of the soil, the fossil formation again showed itself, not only on these hills, but also on the rocks that were in the channel.
