Yesterday, being the King's birthday, Mr. Cunningham planted under Mount Brogden acorns, peach and apricot-stones, and quince-seeds, with the hope rather than the expectation that they would grow and serve to commemorate the day and situation, should these desolate plains be ever again visited by civilized man, of which, however, I think there is very little probability.

Our observation placed the situation of the tent in lat. 34. 13. 33. S., long. 146. E.; the variation of the compass 8. 08. E.

June 6.—A mild pleasant morning: set forward on our journey to the westward and north-west, in hopes of finding a better country: at two o'clock halted about two miles from Peel's range, after going about eight miles through a very thick cypress scrub; the country equally bad as on any of the foregoing days. We saw no signs of water during our route: the whole country seems burnt up with long continued drought; no traces of natives, or any game seen.

After two hours' search a small hole of water was found at the foot of the range, sufficient for the horses, and in a hole in the rocks a little clearer was procured for ourselves.

June 7.—Set forward to the north-west, the horses being a little fresher than for some days past. Halted at four o'clock, having gone ten miles through a country which, for barrenness and desolation, can I think have no equal; it was a continued scrub, and where there was timber it chiefly consisted of small cypress: we saw no water as usual, but stopped on some burnt grass near the base of a low range of stony hills west of Peel's range, from which we are distant eight or ten miles. These ranges abound with native dogs; their howlings are incessant, day as well as night: as we saw no game, their principal prey must be rats, which have almost undermined this loose sandy country.

As we had brought a small keg of water with us, we did not on this occasion suffer absolute want: we hope that the instinct of the horses would lead them to water in the course of the night—but we were too sanguine.

Our spirits were not a little depressed by the desolation and want that seemed to reign around us: the scene was never varied, except from bad to worse. However, the scarcity of water and grass for the horses are our greatest real privations, for the temperature is mild and equable beyond what could be expected at this season, and it is this circumstance alone that enables us to proceed: the horses are too much reduced to endure rainy weather, even if the loose soil of the country would permit us to travel over it.

June 8.—During the night there was light rain. At daylight sent out in search of water, but all our efforts proved unsuccessful. Peel's range being the nearest high land, I determined to search the base of it, in hopes of finding water, since it was impossible that either men or horses could long endure this almost constant privation of the first necessary of life. I accordingly set off towards the range, but was prevented from making it by impenetrable scrubs: we then returned to the range a little to the west of the tent, whence we could see a considerable distance to the west and north-west; it is impossible to imagine a prospect more desolate. The whole country in these directions, as far as the eye could reach, was one continued thicket of eucalyptus scrub: it was physically impossible to proceed that way, and our situation was too critical to admit of delay; it was therefore resolved to return back to our last station on the 6th under Peel's range, if for no other purpose than that of giving the horses water. I felt that by attempting to proceed westerly I should endanger the safety of every man composing the expedition, without any practical good arising from such perseverance: it was therefore deemed more prudent to keep along the base of Peel's range to its termination, having some chance of finding water in its rocky ravines, whilst there was none at all in attempting to keep the level country. It was too late to pursue this resolution this evening.

June 9.—During the night heavy rain. At eight o'clock set off on our return to our halting-place of the 6th, the horses having been now forty-eight hours without water. We had scarcely proceeded a mile when it began to rain hard, and continued to do so without intermission until we stopped at the place where water had been previously found: it was by this time two o'clock, the horses failed, and the people were in little better condition, not having tasted any thing since the evening before. All our clothes were wet through, a circumstance which added greatly to the unpleasantness of our situation.

The true nature of the soil was fully developed by this day's rain. Being in dry weather a loose light sand without any apparent consistency, it was now discovered to have a small portion of loam mixed with it, which, without having the tenacity of clay, is sufficient to render it slimy and boggy: I am quite satisfied that two days' rain will at any time render this country impassable. The mortification and distress of mind I felt at being obliged to take a retrograde direction was heightened by seeing the horses struggling under loads far beyond their present powers, their labour rendered still more trying by the miserable country they were obliged to pass through.
