Sandstone cropped out in several places, and red quartz pebbles were very abundant in some parts of the river; the sands of its bed are so triturated that no one would ever surmise the existence of granitic rocks, at sixteen or twenty miles higher up. The whole country was flat; no hill was visible, but, towards the end of our day's journey, we crossed a few slight undulations.
During the night of the 14th, southerly winds were followed by a gale from the eastward, with scud and drizzling rain. The morning of the 15th was cloudy with a little rain; wind southerly. Early in the night, a strong east-wind with drizzling long rain set in, but cleared up at midnight. The morning of the 16th was cloudy, with a southerly wind. Our lat. was 21 degrees 39 minutes 58 seconds.
March 17.--Mr. Gilbert and Brown went forward in search of water, supposing that they would find it at a convenient distance, but were unsuccessful, and, as they had taken neither guns nor provisions, they were obliged to return. Keeping, however, a little more to the left, on their return, they came to two fine water-holes at the foot of some ironstone ridges, where they passed the night, and reached the camp the following day, having had nothing to eat for twenty-four hours. The camp was then moved to these water-holes, about nine miles off, in a due west course. Fine water-holes were passed at a short half-mile from our camp; and, after crossing the northern anabranch of the river, we again found water.
The detection of isolated water-holes in a wooded country, where there is nothing visible to indicate its presence, is quite a matter of chance. We have often unconsciously passed well-filled water-holes, at less than a hundred yards distant, whilst we were suffering severely from thirst. Our horses and bullocks never showed that instinctive faculty of detecting water, so often mentioned by other travellers; and I remember instances, in which the bullocks have remained the whole night, not fifty yards from water-holes, without finding them; and, indeed, whenever we came to small water-holes, we had to drive the cattle down to them, or they would have strayed off to find water elsewhere. On several occasions I followed their tracks, and observed they were influenced entirely by their sight when in search of it; at times attracted by a distant patch of deeper verdure, at others following down a hollow or a watercourse, but I do not recollect a single instance where they found water for themselves. The horses, however, were naturally more restless and impatient, and, when we approached a creek or a watercourse after a long journey, would descend into the bed and follow it for long distances to find water; giving great trouble to those who had to bring them back to the line of march. Whenever they saw me halt at the place where I intended to encamp, they not only quickened their pace, but often galloped towards me, well knowing that I had found water, and that they were to be relieved of their loads. In looking for water, my search was first made in the neighbourhood of hills, ridges, and ranges, which from their extent and elevation were most likely to lead me to it, either in beds of creeks, or rivers, or in water-holes, parallel to them. In an open country, there are many indications which a practised eye will readily seize: a cluster of trees of a greener foliage, hollows with luxuriant grass, eagles circling in the air, crows, cockatoos, pigeons (especially before sunset), and the call of Grallina Australis and flocks of little finches, would always attract our attention. The margins of scrubs were generally provided with chains of holes. But a flat country, openly timbered, without any break of the surface or of the forest, was by no means encouraging; and I have frequently travelled more than twenty-five miles in a straight line without obtaining my object, In coming on creeks, it required some experience in the country, to know whether to travel up or down the bed: some being well provided with water immediately at the foot of the range, and others being entirely dry at their upper part, but forming large puddled holes, lower down, in a flat country. From daily experience, we acquired a sort of instinctive feeling as to the course we should adopt, and were seldom wrong in our decisions.
The ridges, near the water-holes on which we were encamped, are composed of an igneous rock containing much iron, with which the water was impregnated to such a degree, that our tea turned quite black and inky. The natives were very numerous in these parts, and their tracks were everywhere visible. They had even followed the tracks of Mr. Gilbert's and Brown's horses of the preceding day.
The night was bright; the day cloudy, and the wind easterly. I went with Charley, in the afternoon of the 17th, to examine the extent of the scrubby country, of which Mr. Gilbert had given us so poor an account. The channel of the river became narrow and deep, with steep banks, as it enters the scrub, and there the flooded gums entirely disappeared. The scrub is about eight miles long, and from two to three miles broad, and is tolerably open. The Bricklow is here a real tree, but of stunted growth, with regularly fissured bark, like that of the Ironbark (Eucalyptus resinifera). It has long broad falcate phyllodia, whilst another species of the same size has an irregular scaly bark, with small phyllodia, but of a greyer colour than those of the common Bricklow. Both species grow promiscuously together. Where the river left the scrub, it entered into a wild water-worn box flat, and cut up into several irregular channels, lined by a dense thicket of narrow-leaved Melaleucas of stunted growth and irregular shapes. The Box-tree itself is here a different species, the bark has deeper fissures, and the young wood is very yellow. I shall distinguish it by the name of "Water-box," as it grows exclusively near creeks, or on the neighbouring flats. I first observed it at the Mackenzie; its bark strips freely, but the stem is too short and irregular to be of any use.
In passing a low hill, at the foot of which the box-flat commenced, we came on a very distinct path of the natives, which led us to a deep water-hole, covered with luxuriant grass; containing but a small quantity of water. Farther on we came to a second hole better supplied, and to a third; and at last Charley cried out, "Look there, Sir! what big water!" and a long broad sheet of water stretched in sweeps through a dense Bauhinia and Bricklow scrub, which covered its steep banks. It is a singular character of this remarkable country, that extremes so often meet; the most miserable scrub, with the open plain and fine forest land; and the most paralysing dryness, with the finest supply of water.
Swarms of ducks covered the margin of the lake; pelicans, beyond the reach of shot, floated on its bosom; land-turties plunged into its waters; and shags started from dead trees lying half immersed, as we trod the well-beaten path of the natives along its banks. The inhabitants of this part of the country, doubtless, visit this spot frequently, judging from the numerous heaps of muscle-shells. This fine piece of water, probably in the main channel of the Suttor, is three miles long, and is surrounded with one mass of scrub, which opens a little at its north-western extremity.
March 10.--I continued my ride, ten or twelve miles down the river; the scrub continued, but the immediate neighbourhood became a little more open; several trees were observed, that had been recently cut by the natives in search of honey or opossums. Emus were very numerous; sometimes a solitary bird, and at others two, three, four, and up to thirteen together, were seen trotting off in long file, and now and then stopping to stare at us. We caught a bandicoot with two young ones, which gave us an excellent luncheon. When we left the lake, Charley thought he could distinguish a plain to the northward; and, riding in that direction, I was agreeably surprised to find that the scrub did not extend more than a mile and a-half from the river; and that, beyond it, plains and open forest extended far to the northward; and fine ridges with most excellent feed, to the southward. The traveller who is merely following the course of a river, is unable to form a correct idea of the country farther off, unless hills are near, from which he may obtain extensive views. At the water-worn banks of the Mackenzie, I little expected that we were in the vicinity of a country like that of Peak Range; and I am consequently inclined to believe that much more available land exists along the banks of the Suttor, where its valley is covered with scrub, than we know anything about.
March 19.--The camp was removed to the lake of the Suttor, about twelve miles and a-half N. 80 degrees W. We chased a flock of emus, but without success; four of my companions went duck-shooting, but got very few; the others angled, but nothing would bite.
