After crossing the line of ponds and a slight elevation beyond them we came upon a channel of considerable breadth, which contained several other very large ponds separated by quicksands, which afforded but a precarious passage for the pack-animals. Both banks were steep, the average width exceeding fifty yards. Beyond this river channel the wood consisted chiefly of casuarinae. We next penetrated through two scrubs of dwarf eucalypti; and some trees of the callitris were also seen. At six miles the woods assumed a grander character; masses of casuarinae enclosed open spaces covered with rich grass; and, being in some directions extensive, afforded park-like vistas, which had a pleasing effect from the rich combination of verdure and shade in a season of excessive heat. In one of these grassy alleys a large kangaroo was seen, the first since we left the upper part of the Gwydir. The absence of this animal from the plains and low grounds was remarkable, and we had reason to conclude that he seldom frequents those parts. At eight miles our course was intercepted by a deep and rapid river, the largest that we had yet seen. I had approached within a few yards of the brink; and I was not aware of its being near until I saw the opposite water-worn shore, and the living waters hurrying along to the westward. They were white and turbid, and the banks, consisting of clay, were nearly perpendicular at this point, and about twenty feet higher than the surface of the stream. On further examination I found that the course was very tortuous and the water deep. My horse was however got across by a man wading up to the neck. The softness of the clay near the stream at some parts, and the steep water-worn face of the banks at others, rendered the passage difficult. SEND BACK FOR THE PARTY ON THE GWYDIR. We were all delighted however to meet such an obstruction, and I chose a favourable spot for our camp within a bend of the river; and I made arrangements for bringing forward the party left with Mr. White on the Gwydir, also for the construction of a boat by preparing a saw-pit and looking for wood favourable for that purpose. There was abundance of rich grass along the banks of this river; and here our horses at length enjoyed some days of rest. January 24. Early this morning I sent back a party of the men, with the freshest of the bullocks to Mr. White, to whom I also enclosed a letter for Mr. Finch which I requested might be concealed in a tree with certain marks. I hoped however that by that time Mr. Finch might have overtaken Mr. White's party. Four men remained with me, namely two carpenters, a sawyer's man, and my own servant. The morning was cloudy, and a refreshing shower fell at nine A.M. ABUNDANCE OF THREE KINDS OF FISH.
