An accident happened to the vessel containing the mercury of the artificial horizon, by which the greater part was lost, leaving scarcely sufficient for use. It had been a matter of surprise to me that such a misfortune had not occurred sooner, the box containing the instruments, etc., being so shaken by the horse forcing his way through the scrubs, that I considered myself extremely fortunate not to have been deprived of the use of them long before. To carry barometers, and other delicately constructed mathematical instruments, safely through such a journey as the present is impossible. Our course made good was N. 68 E., distance thirteen miles and a half. The evening fine and clear.
August 6.—Proceeded on our course, which led us for nine or ten miles through what might be termed an open forest country, with respect to the timber growing on it, but it was overrun with mimosa and acacia bushes, many of which were coming into flower, relieving in some measure the sombre foliage of the cypress and box trees which were scattered among them: it was rather an elevated tract that we travelled through, with such gentle rises and descents as to be almost imperceptible from a level surface. I ascended a hill about three miles north of the road, but could see nothing remarkable in any direction, the whole appearing irregularly broken into low hills and valleys, thickly clothed with small trees and bushes. At the eighth mile we came upon a small waterhole, which our poor horses soon emptied; again at the tenth mile, just at the commencement of a very broken stony range, we also found a few gallons of water, which the horses also enjoyed, it being much too muddy for our use; and besides, we had hopes that after passing the range of hills in which we were about to enter, we should find water on the other side. The range continued in short broken hills for upwards of three miles and a half, and led through such a country as distressed both men and horses exceedingly: the surface was covered with small quartz stones, without herbage of any kind. The box and cypress trees disappeared, and their place was supplied by a numerous species of iron bark, between which the acacia, mimosa, and a new prickly acacia rendered it almost impossible to force a passage: after enduring this for upwards of three miles and a half, we began to descend, by keeping a more easterly course; but before we could come into a better country, either for grass or water, we were obliged to halt for the night, being too much fatigued to proceed farther.
Our search after water was not attended with success, but the ground being extremely boggy, we were in hopes of procuring a little by digging. Our spade, which had so unfortunately been left at Bathurst, would now have been of the most essential service, but the carpenter's adze proved a useful substitute. Choosing a place which seemed most likely to have received the drainings of the hills, and on which a little rain-water still remained, we dug a tolerably good well, and in a few hours were rewarded by obtaining near a quart of thick muddy water per man, which by boiling, skimming, and straining, was rendered palatable to persons who must otherwise have gone without their dinner or breakfast the next morning, it being impossible to eat either our bread or pork without something to quench our thirst.
The soil of the country passed over was of the same red, sandy description as on former days; the hills were covered with small pieces of broken white quartz, and occasionally a large granite rock showed itself from beneath the surface. The botanical productions of the hills seemed also to undergo a considerable change, indicating, as we would fain hope, that a better country is not far off. Several new plants were acquired today, some of which were very beautiful. Our course made good was N. 71. E., distance thirteen miles and a half.
August 7.—The horses suffered much from want of food and water; but it is absolutely necessary to proceed and get into a better country with all the expedition which we are capable of using, and which the nature of this country will allow. It is some consolation to us that the horses are but lightly loaded, by reason of our not being now encumbered with much provisions, and are consequently enabled to travel farther and better. At half past eight o'clock we again set forward, and for four miles and a quarter continued to pass through the same thick, barren country as yesterday, the ground being absolutely covered with acacia of various species, some extremely beautiful; after which the country became more open; the grass had been burnt, and the marks of the mogo or stone hatchet on the trees, made by the wandering natives of these deserts in search of food, gave us renewed hopes of soon coming to water. A rose-hill parrot was seen for the first time for many months, and we were farther fortunate in killing a fine kangaroo. The country seemed to improve as we advanced, and at the ninth mile, as we had been gradually ascending, we were gratified by an open prospect to the eastward, which showed low gentle hills and valleys thinly studded with trees. The broom-grass, now dead, gave them a white appearance, and, contrasted with the acacia in full flower, and the darker foliage of the trees, gave the whole the most pleasing and varied aspect. To the north-west round to the north, the country was nearly the same; but from north to north-east by east, it was more broken into low barren hills; the tops and sides covered with iron bark, and cypress growing among the interstices of the granite rocks. We had however seen no water, but there was something in the aspect of the whole country that flattered our hopes of finding it in some of the valleys that lay in our course; nor were we disappointed: after going rather more than four miles farther, through a very open country, thickly covered with broom-grass (killed by the frost), we ascended a rocky hill of moderate elevation, connected with others lying east and west: opposite to us was a low rocky range, the summits of which were clothed with iron bark and casuarina trees. We saw from this hill Mount Melville bearing N. 175., Mount Cunningham N. 189 1/2., Mount Maude N. 192., a round mount N. 218., named Mount Riley, a gap in a range N. 283., distance about thirty miles: descending into the valley we found plenty of water, to our great relief, as the horses were quite exhausted, and without this seasonable supply would have been altogether unable to proceed farther. The grass in the valley, although perished by the winter's frost, was very tolerable, and the worn out state of the horses made me determine to remain here to-morrow, to recruit them a little before we proceeded farther.
The country we have passed through this day afforded some of the most beautiful specimens of acacia which we had yet seen, at the same time that they were quite new in the species. The soil however was still of the same description, red and sandy, but for the last five or six miles more firm and compact; many of the plants were recognized as having been originally seen in the neighbourhood of the Macquarie River, and not since: this, with the more generally open appearance of the country, gave us hopes that in a few days we should be fortunate enough to fall in with that stream, which would free us from any farther apprehensions of suffering from want of water; for in that event it is my intention to keep in its immediate vicinity until our arrival at Bathurst. Our course made good was N. 71. E., distance thirteen miles and a quarter.
August 8.—Made the usual observations to ascertain our situation, the result of which placed us in lat. 32. 47. 58. S., long. 147. 23. E., and the variation of the needle 5. 20. E. The valley in which we encamped is enclosed by forest hills on all sides but the east, affording us plenty of water from what is, even at this dry season, a perceptible stream. The grass however was quite killed by the frost, and, although abundant, did not afford such nourishment to the horses as their condition required, insomuch that if we fall in with a part of the country that has been burnt in the course of to-morrow's route, I shall give them a day's rest.
Kangaroos of a very large size abound in every direction around us: our dogs killed one weighing seventy or eighty pounds, which proved a great and refreshing acquisition to us.
To the valley I gave the name of Emmeline's Valley, and the hill from which we corrected our survey with Mount Melville and Mount Cunningham, Macnamara's Hill. The day was clear and mild, and in the course of it some new and fine plants were procured.
August 9.—The morning fine and pleasant. At half past eight we left the valley, intending still to keep our course north of east, as the most likely point on which to make the Macquarie River, from which, judging by the botanical productions of that stream, we cannot be very far.
