Whilst Mr. Hume led the party down the river, I rode up its northward bank, to examine it more closely. I found it to be a serpentine sheet of about three miles in length, gradually decreasing in depth until it separated into two small creeks. In following one of them up, I observed that they re-united at the distance of about two miles, and that the lagoon was filled from the eastward, and not by the river as I had at first supposed. The waters at the head of the lagoon were putrid, nor was there a fish in, or a wild fowl upon it. The only bird we saw was a beautiful eagle, of the osprey kind, with plumage like a sea gull, which had a nest in the tree over the tents.
In turning to overtake the party I rode through a great deal of acacia scrub, and on arriving at the place at which
I expected to have overtaken them, I found they had pushed on.
The Castlereagh, as I rode down it, diminished in size considerably, and became quite choked up with rushes and brambles. Rough-gum again made its appearance, with swamp-oak and a miserable acacia scrub outside. The country on both sides of the river seemed to be an interminable flat, and the soil of an inferior description.
I came up with with Mr. Hume about 1 o'clock and we again pushed forward at 3, and halted for the night without water, the want of which the cattle did not feel. The river held a general westerly course, and the country in its neighbourhood became extremely depressed and low. On the following day we moved forward a distance of not more than nine miles, through a country on which, at first, the acacia pendula alone was growing on a light alluvial soil. The river had many back drains, by means of which, in wet seasons, it inundates the adjacent plains. It was evident, however, that they had not been flooded for many years; and, notwithstanding that the country was low, the line of inundation did not appear to be very extensive, nor were there any reeds growing beyond the immediate banks of the river. Swamp-oak and rough-gum again prevailed near the stream at our halting place, and the improvement that had taken place, both in the country and in the Castlereagh, had induced us to make so short a journey; for not only was there abundance of the grass for the animals, but large ponds of water in the river. Some natives
had only just preceded us down it: we came upon their fires that were still smoking; and upon them were the remains of some fish they had taken, near which they had left a cumbrous spear. The circumstances cheered us with hopes that an improvement would take place in the country, and that some new feature would soon open upon us. In the course of the following day, however, every favorable change, both in the river and in the country, disappeared. The latter continued extremely depressed, and in general open, or lightly covered with acacia pendula; the former dwindled into a mere ditch, choked up with brambles and reeds, and having only here and there a stagnant pool of water. We travelled on a N.W. 1/2 W. course for about ten miles, and again stopped for the night without water. In the course of the afternoon, we traversed several flats, on which the rough-gum alone was growing. These flats were evidently subject to flood; and contained an alluvial soil.
They became more frequent as we travelled down the river, and the work was so heavy for the animals, that I was obliged to keep wide of them, in doing which we struck upon a creek of large size, coming from the N.E. and, having crossed, we traversed its right bank to its junction with the Castlereagh, and stopped close to it at a pond of water, though the feed for the animals was bad. The country to the left of the river, though somewhat high, was the same, in essential points, as that to the right.
The Castlereagh seemed to have increased in size below the creek, but still it had no resemblance to a river. We had not proceeded very far down its banks, on the 18th, when we crossed a broad footpath leading to it from the interior. I turned my horse to the left, and struck upon a long sheet of water, from which I startled a number of pelicans. It was evident that the natives had recently been in the neighbourhood, but we thought it probable they might have been a hunting party, who had returned again to the plains. The whole track we passed over during the day was miserably poor and bare of vegetation, nor did the appearance of the country to the N.E. indicate any improvement. We lost the traces of the natives immediately after crossing their path or beat, and again found the bed of the river dry, after we had passed the sheet of water to which it led. The soil was so rotten and yielding, that the team knocked up early; indeed, it was a matter of surprise to me that they should not have failed before. The river made somewhat to the westward with little promise of improvement. The wretched appearance of the country as we penetrated into it, damped our spirits; we pressed on, however, with difficulty, over ground that was totally destitute of vegetation. Instead of lofty timber and a living stream, we wandered along the banks of an insignificant watercourse, and under trees of stunted size and scanty foliage. We stopped on the 20th at the angle of a creek, in which there was some dry grass, in consequence of the animals being almost in a starving state, but even here they had but little to eat.
A violent thunder-storm passed over us in the afternoon, but it made no change in the temperature of the air. The weather, although it had been hot and sultry, had fallen far short of the intense heat we experienced in crossing the marshes of the Macquarie, when it was such as to melt the sugar in the canisters, and to destroy all our dogs; and our nights were now become agreeably cool.
We still, however, continued to travel over a dead level, nor was a height or break visible from the loftiest trees we ascended. A little before we stopped at the creek, we surprised a party of natives; old men, women, and children. They were preparing dinners of fish in much larger quantities than they could have devoured—probably for a part of the tribe that were absent; but the moment they saw us they fled, and left every thing at our mercy. On examining the fish, we found them totally different from any in the Macquarie, and took two of the most perfect to preserve. In the afternoon one of the men came to inform me that the tribe was coming down upon us.
