The greatest difficulty against which we had at present to contend was the wind; and I dreaded the exertion it would call for, to make head against it; for the men were so much reduced that I felt convinced they were inadequate to any violent or prolonged effort. It still blew fresh at 8 p.m., but at that time it began to moderate. It may be imagined that I listened to its subdued gusts with extreme anxiety. It did not wholly abate until after 2 a.m., when it gradually declined, and about 3 a light breeze sprung up from the N. E.
We had again placed sticks to ascertain with more precision the rise of tide, and found it to be the same as in the river. In the stillness of the night too we thought we heard the roaring of the sea, but I was myself uncertain upon the point, as the wind might have caused the sound.
From the top of the hill from which we had obtained our first view of the lake, I observed the waves breaking upon the distant headland, and enveloping the cliff in spray; so that, independent of the clearness of the horizon beyond it, I was further led to conclude that there existed a great expanse of water to the S.W.; and, as that had been the direction taken by the river, I thought it probable that by steering at once to the S.W. down the lake, I should hit the outlet. I, consequently, resolved to gain the southern extremity of the lake, as that at which it was natural to expect a communication with the ocean would be found.
GEOLOGICAL FORMATION.
At 4 we had a moderate breeze, and it promised to strengthen; we lost no time therefore in embarking, and with a flowing sheet stretched over to the W.S.W., and ran along the promontory formed by the right bank of the Murray. We passed close under its extreme point at nine. The hills had gradually declined, and we found the point to be a flat, elevated about thirty feet above the lake. It was separated from the promontory by a small channel that was choked up with reeds, so that it is more than probable that the point is insulated at certain periods; whilst in its stratification it resembled the first cliffs I have described that were passed below the Darling. It is a remarkable fact in the geology of the Murray, that such should be the case; and that the formation at each extremity of the great bank or bed of fossils should be the same. Thus far, the waters of the lake had continued sweet; but on filling a can when we were abreast of this point, it was found that they were quite unpalatable, to say the least of them. The transition from fresh to salt water was almost immediate, and it was fortunate we made the discovery in sufficient time to prevent our losing ground. But, as it was, we filled our casks, and stood on, without for a moment altering our course.
PASSAGE ACROSS THE LAKE—ITS SHALLOWNESS.
It is difficult to give a just description of our passage across the lake. The boisterous weather we had had seemed to have blown over. A cool and refreshing breeze was carrying us on at between four and five knots an hour, and the heavens above us were without a cloud. It almost appeared as if nature had resisted us in order to try our perseverance, and that she had yielded in pity to our efforts. The men, relieved for a time from the oar, stretched themselves at their length in the boat, and commented on the scenery around them, or ventured their opinions as to that which was before them. Up to this moment their conduct had been most exemplary; not a murmur had escaped from them, and they filled the water-casks with the utmost cheerfulness, even whilst tasting the disagreeable beverage they would most probably have to subsist on for the next three or four days.
As soon as we had well opened the point, we had a full view of the splendid bay that, commencing at the western most of the central points, swept in a beautiful curve under the ranges. No land was visible to the W.N.W. or to the S.S.W.: in both these quarters the lake was as open as the ocean. It appeared, therefore, that the land intermediate was an island. To the north the country was extremely low, and as we increased our distance from it we lost sight of it altogether. At noon we were nearly abreast of the eastern headland, or in the centre of the strait to which I have alluded. At this time there was an open sea from W.N.W. to N. by E. A meridian altitude gave our latitude 35 degrees 25 minutes. The land to our left was bold and precipitous; that to the right was low and wooded; and there was evidently a considerable space between the shores of the lake and the base of the ranges. The country to the eastward was hidden from us by the line of cliffs, beyond which from E.S.E. to W.S.W. there was an open sea. We had kept the lead going from the first, and I was surprised at the extreme shallowness of the lake in every part, as we never had six feet upon the line. Its bottom was one of black mud, and weeds of enormous length were floating on its surface, detached by the late gales, and which, from the shallowness of the lake, got constantly entangled with our rudder.
We tried to land on the eastern point, but found the water too shallow, and were obliged to try the western shore. In passing close under the head, we observed several natives upon it, who kindled a large fire as soon as they saw they were noticed, which was answered from every point; for, in less than ten minutes afterwards, we counted no fewer than fourteen different fires, the greater number of which were on the side of the ranges.
