The abundance of white cockatoos and crows, which is constantly about the banks of the river, is astonishing; the other smaller birds appear to be also common to the east coast. Since we have been on the river, no recent traces of the natives have been seen; here, as higher up the river, they rather seem to shun it, and frequent the higher grounds in preference: perhaps their food is more easily procured on those grounds than on the river, particularly as they appear unacquainted with the method of taking the fish by hook and line.
As the horses were by no means in a condition to be forced, I determined to remain here to-morrow to refresh them, and set forward again on Saturday morning.
June 27.—After breakfast, I sent two men down the river to examine our route for to-morrow: one of them crossed over to the north side, to endeavour to reach some open spaces of plains which we saw from our tent. In the course of the afternoon they both returned; one, who had gone a little way inland on this side, could make no progress for extensive swamps, covered with water of the depth of from two to four feet, and abounding with black swans and wild fowl. The other man was also unable to reach the plains on the other side for water supplied from a creek of the river, and forming an extensive and deep morass.
With these unfavourable reports before us, we determined to keep close to this bank of the river during tomorrow's journey; and if we should he prevented by its overflowing from proceeding, to return, and endeavour to round the morasses to the southward. Latitude by observation 33. 22. S., long. 145. 24. 15. E.; and the variation of the compass 7. 30. E.
June 28.—Upon farther consideration, it appeared more advisable that the horses should proceed round the south edge of the morasses rather than be obliged to return; after keeping by the river for three or four miles, which to all appearance was as far as we should be enabled to proceed in that direction. However, that there might remain no doubt as to which was the preferable route, I adhered to my determination to go down the banks of the river myself as far as I could, and return by the route which the horses were to take. Our principal object being to keep as close to the stream as possible, with reference to the ability of the horses to travel over the ground.
The horses set forward at nine o'clock$ and I proceeded down the stream five or six miles, when I was obliged to return to the place from which I set out, being unable to cross a small drain that led from the swamps to the river. I could in no place deviate above fifty yards from the river without being bogged, the water lying in some places eighteen inches deep, and in holes, much deeper. I attempted several times to proceed southerly, intending to cross the track which I presumed Mr. Evans would be obliged to take, but I was unable to accomplish it. The route taken by Mr. Evans and the horses led along the edge of extensive morasses covered with water; we proceeded nine or ten miles, when the morasses almost assumed the appearance of lakes; very extensive portions of them being free from timber, and being apparently deep water. South of the edge of the morass along which we travelled, the country was a barren scrub, and in places very soft; the horses falling repeatedly during the day.
At the place where we stopped for the evening, I calculated that we were about five miles south of the river; on the edge of a very large lagoon, or lake. The country was so extremely low, that before I returned up the river to rejoin the horses, wishing to see what the openings on the other side were, I ascended a large gum tree, which enabled me to see that the flats opposite were similar to those on the south side. Our progress, upon the whole although we had travelled upwards of ten miles, did not exceed in a direct line five miles. The lagoons abound with water fowl, although we were not so fortunate as to obtain any; we were however amply compensated by our dogs killing a fine large emu. Various old marks of natives having visited these lakes, but none recent.
June 29.—Our course in the first instance was directed in such a manner as to compass the lagoons, which after travelling about three miles and a half to the south-west, we accomplished, and again came upon the stream; the country thence backward bore the marks of being at some periods near three feet under water, and was covered with small box-trees: the country from our rejoining the river, to the place at which we stopped for the evening, consisted of barren plains, extending on both sides of the stream to a considerable distance backward. The points of the bends of the river were universally wet swamps with large lagoons; the back land, though equally subject to flood, was now dry; but the travelling was very heavy, the ground being a rotten, red, sandy loam, on which nothing grew but the usual production of marshes. I never saw a stream with so many sinuosities; in many places a quarter of a mile would cut off at least three miles by the river. The stream was in places much contracted, sand banks stretching nearly across; its medium depth was about eight feet.
There was not the smallest eminence whence a view might be obtained, the country appearing a dead level; and although on these plains we could see for some distance all round, yet there was not a rising ground in any direction. The plains on the north side of the stream were named Holdsworthy; and those on the south, Harrington. We were lucky enough to procure two fine emus.
June 30.—The first two or three miles were somewhat harder travelling than the greater part of yesterday. Immense plains extended to the westward, as far as the eye could reach. These plains were entirely barren, being evidently in times of rain altogether under water, when they doubtless form one vast lake: they extended in places from three to six miles from the margin of the stream, which on its immediate borders was a wet bog, full of small water holes, and the surface covered with marsh plants, with a few straggling dwarf box-trees. It was only on the very edge of the bank, and in the bottoms of the bights, that any eucalypti grew; the plains were covered with nothing but gnaphalium: the soil various, in some places red tenacious clay, in others a dark hazel-coloured loam, so rotten and full of holes that it was with difficulty the horses could travel over them. Although those plains were bounded only by the horizon, not a semblance of a hill appeared in the distance; we seemed indeed to have taken a long farewell of every thing like an elevation, whence the surrounding country could be observed. To the southward, bounding those plains in that direction, barren scrubs and dwarf box-trees, with numberless holes of stagnant water, too clearly proclaimed the nature of the country in that quarter. We could see through the openings of the trees on the river that plains of similar extent occupied the other side, which has all along appeared to us to be (if any thing) the lower ground. We travelled in the centre of the plains, our medium distance from the river being from one to two miles; and although we did not go above thirteen miles, some of the horses were excessively distressed from the nature of the ground.
