During the night of the 18th of September a few heat-drops of rain fell. I sent Robinson away to the plain camp, feeling sure he would find the rover there. A hot wind blew all day, the sand was flying about in all directions. Robinson got the horse at last at the plain, and I took special care to find a pair of hobbles for him for this night at all events. The flies were an intolerable nuisance, not that they were extraordinarily numerous, but so insufferably pertinacious. I think the tropic fly of Australia the most abominable insect of its kind. From the summit of the hill I ascended on Sunday, I found the line of mountains still ran on to the west, the furthest hills appeared fifty miles away. As they extend so far, and are the principal features in sight, I shall follow them, in hopes of meeting some creek, or river, that may carry me on to the west. It is a remarkable fact that such high hills as I have been following should send out no creek whose course extends farther than ten or twelve miles. I could trace the creek I am now on by its timber for only a few miles, its course appearing south of west. The country in its immediate neighbourhood is open, and timbered with fine casuarina trees; the grass is dry and long, and the triodia approaches to within a quarter of a mile of it. The line of hills I previously mentioned as running along to the south of us, we had now run out. I named them Gardiner's Range, after a friend of Mr. Carmichael's. There is, however, one small isolated hill, the furthest outpost of that line, some three miles away to the south-west; the creek may probably take a bend down towards it. I called it Mount Solitary. This creek is rather well timbered, the gum-trees look fresh and young, and there is some green herbage in places, though the surface water has all disappeared.

There was so little water at the camp tank, we had to send the horses up the creek three miles to water, and on their return I was not sorry to be moving again, for our stay at these two last camps had been compulsory, and the anxiety, trouble, and annoyance we had, left no very agreeable reminiscences of the locality in our minds.

We travelled along the creek all day, cutting off the bends, but without seeing any signs of water: towards evening we set to work to try if we could get any by digging. In about four feet, water began to drain in, but, the sand being so loose, we had to remove an enormous quantity to enable a horse to drink. Some of the horses would not go into it, and had to be watered with a canvas bucket. The supply seemed good, but it only drained in from the sides. Every time a horse drank we had to clear out the sand for the next; it therefore took until late before all were satisfied. The country was still open, and timbered with fine black oak, or what is so called in Australia. It is a species of casuarina, of the same family but distinct from the beautiful desert oak. Triodia reigned supreme within half a mile. At this camp the old grass had been burnt, and fresh young green shoots appeared in its place; this was very good for the horses. A few drops of rain fell; distant rumblings of thunder and flashes of lightning now cooled the air. While we were at breakfast the next morning, a thunderstorm came up to us from the west, then suddenly turned away, only just sprinkling us, though we could see the rain falling heavily a few yards to the south. We packed up and went off, hoping to find a better watered region at the hills westwards. There was an extraordinary mount a little to the west of north from us; it looked something like a church; it was over twenty miles away: I called it Mount Peculiar. Leaving the creek on our left, to run itself out into some lonely flat or dismal swamp, known only to the wretched inhabitants of this desolate region—over which there seems to brood an unutterable stillness and a dread repose—we struck into sandhill country, rather open, covered with the triodia or spinifex, and timbered with the casuarina or black oak trees. We had scarcely gone two miles when our old thunderstorm came upon us—it had evidently missed us at first, and had now come to look for us—and it rained heavily. The country was so sandy and porous that no water remained on the surface. We travelled on and the storm travelled with us—the ground sucking up every drop that fell. Continuing our course, which was north 67° west, we travelled twenty-five miles. At this distance we came in sight of the mountains I was steering for, but they were too distant to reach before night, so, turning a little northward to the foot of a low, bare, white granite hill, I hoped to find a creek, or at least some ledges in the rocks, where we might get some water. Not a drop was to be found. Though we had been travelling in the rain all day and accomplished thirty miles, we were obliged to camp without water at last. There was good feed for the horses, and, as it was still raining, they could not be very greatly in want of water. We fixed up our tent and retired for the night, the wind blowing furiously, as might reasonably be expected, for it was the eve of the vernal equinox, and this I supposed was our share of the equinoctial gales. We were compelled in the morning to remove the camp, as we had not a drop of water, and unless it descended in sheets the country could not hold it, being all pure red sand. The hill near us had no rocky ledges to catch water, so we made off for the higher mountains for which we were steering yesterday. Their nearest or most eastern point was not more than four miles away, and we went first to it. I walked on ahead of the horses with the shovel, to a small gully I saw with the glasses, having some few eucalypts growing in it. I walked up it, to and over rocky ledges, down which at times, no doubt, small leaping torrents roar. Very little of yesterday's rain had fallen here; but most fortunately I found one small rock reservoir, with just sufficient water for all the horses. There was none either above or below in any other basin, and there were many better-looking places, but all were dry. The water in this one must have stood for some time, yesterday's rain not having affected it in the least. The place at which I found the water was the most difficult for horses to reach; it was almost impracticable. After finding this opportune though awkwardly situated supply, I climbed to the summit of the mount. On the top was a native fig-tree in full bearing; the fruit was ripe and delicious. It is the size of an ordinary marble, yellow when unripe, and gradually becoming red, then black: it is full of small seeds. I was disturbed from my repast by seeing the horses, several hundred feet below me, going away in the wrong direction. And I had to descend before I had time to look around; but the casual glance I obtained gave me the most gloomy and desolate view imaginable; one, almost enough to daunt the explorer from penetrating any farther into such a dreadful region. To the eastward, I found I had now long outrun the old main chain of mountains, which had turned up to the north, or rather north-north-westward; between me and it a mass of jumbled and broken mounts appeared; each separate one, however, was almost surrounded by scrubs, which ran up to the foot of the hill I was upon. Northward the view was similar. To the west the picture was the same, except that a more defined range loomed above the intervening scrubs—the hills furthest away in that direction being probably fifty miles distant. The whole horizon looked dark and gloomy—I could see no creeks of any kind, the most extensive water channels were mere gullies, and not existing at all at a mile from the hills they issued from.

Watering our horses proved a difficult and tedious task; as many of them would not approach the rocky basin, the water had to be carried up to them in canvas buckets. By the time they were all watered, and we had descended from the rocky gully, the day had passed with most miraculous celerity. The horses did not finish the water, there being nearly sufficient to give them another drink. The grass was good here, as a little flat, on which grew some yellow immortelles, had recently been burnt. I allowed the horses to remain and drink up the balance of the water, while I went away to inspect some other gorges or gullies in the hills to the west of us, and see whether any more water could be found. The day was cool and fine.

I climbed to the summit of a hill about 800 feet from its base. The view was similar to yesterday's, except that I could now see these hills ran on west for twelve or fifteen miles, where the country was entirely covered with scrubs. Little gullies, with an odd, and stunted, gum-tree here and there, were seen. Few of these gullies were more than six feet wide, and the trumpery little streams that descend, in even their most flooded state, would be of but little service to anybody. I had wandered up and down hills, in and out of gullies, all the morning, but had met no single drop of water, and was returning disappointed to the camp when, on trying one more small scrubby, dreadfully-rocky little gully which I had missed, or rather passed by, in going out, I was fortunate enough to discover a few small rocky holes full of the purest fluid. This treasure was small indeed, but my gratitude was great; for what pleased me most was the rather strange fact that the water was trickling from one basin to another, but with the weakest possible flow. Above and below where I found this water the gully and the rocks were as dry as the desert around. Had the supply not been kept up by the trickling, half my horses would have emptied all the holes at a draught.

The approach to this water was worse, rougher, rockier, and more impracticable than at the camp; I was, however, most delighted to have found it, otherwise I should have had to retreat to the last creek. I determined, however, not to touch it now, but to keep it as a reserve fund, should I be unable to find more out west. Returning to camp, we gave the horses all the water remaining, and left the spot perfectly dry.

We now had the line of hills on our right, and travelled nearly west-north-west. Close to the foot of the hills the country is open, but covered with large stones, between the interstices of which grow huge bunches of the hideous spinifex, which both we and the horses dread like a pestilence. We have encountered this scourge for over 200 miles. All around the coronets of most of the horses, in consequence of their being so continually punctured with the spines of this terrible grass, it has caused a swelling, or tough enlargement of the flesh and skin, giving them the appearance of having ring-bones. Many of them have the flesh quite raw and bleeding; they are also very tender-footed from traversing so much stony ground, as we have lately had to pass over. Bordering upon the open stony triodia ground above-mentioned is a bed of scrubs, composed chiefly of mulga, though there are various other trees, shrubs, and plants amongst it. It is so dense and thick that in it we cannot see a third of the horses at once; they, of course, continually endeavour to make into it to avoid the stones and triodia; for, generally speaking, the pungent triodia and the mulga acacia appear to be antagonistic members of the vegetable kingdom. The ground in the scrubs is generally soft, and on that account also the horses seek it. Out of kindness, I have occasionally allowed them to travel in the scrubs, when our direct course should have been on the open, until some dire mishap forces us out again; for, the scrubs being so dense, the horses are compelled to crash through them, tearing the coverings of their loads, and frequently forcing sticks in between their backs or sides and their saddles, sometimes staking themselves severely. Then we hear a frantic crashing through the scrubs, and the sounds of the pounding of horse-hoofs are the first notice we receive that some calamity has occurred. So soon as we ourselves can force our way through, and collect the horses the best way we can, yelling and howling to one another to say how many each may have got, we discover one or two missing. Then they have to be tracked; portions of loads are picked up here and there, and, in the course of an hour or more, the horse or horses are found, repacked, and on we push again, mostly for the open, though rough and stony spinifex ground, where at least we can see what is going on. These scrubs are really dreadful, and one's skin and clothes get torn and ripped in all directions. One of these mishaps occurred to-day.

In these scrubs are met nests of the building rat (Mus conditor). They form their nests with twigs and sticks to the height of four feet, the circumference being fifteen to twenty. The sticks are all lengths up to three feet, and up to an inch in diameter. Inside are chambers and galleries, while in the ground underneath are tunnels, which are carried to some distance from their citadel. They occur in many parts of Australia, and are occasionally met with on plains where few trees can be found. As a general rule, they frequent the country inhabited by the black oak (casuarina). They can live without water, but, at times, build so near a watercourse as to have their structures swept away by floods. Their flesh is very good eating.

In ten miles we had passed several little gullies, and reached the foot of other hills, where a few Australian pines were scattered here and there. These hills have a glistening, sheening, laminated appearance, caused by the vast quantities of mica which abounds in them. Their sides are furrowed and corrugated, and their upper portions almost bare rock. Time was lost here in unsuccessful searches for water, and we departed to another range, four or five miles farther on, and apparently higher; therefore perhaps more likely to supply us with water. Mr. Carmichael and I ascended the range, and found it to be 900 feet from its base; but in all its gullies water there was none. The view from the summit was just such as I have described before—an ocean of scrubs, with isolated hills or ranges appearing like islands in most directions. Our horses had been already twenty-four hours without water. I wanted to reach the far range to the west, but it was useless to push all the pack-horses farther into such an ocean of scrubs, as our rate of progress in them was so terribly slow. I decided to return to the small supply I had left as a reserve, and go myself to the far range, which was yet some thirty miles away. The country southward seemed to have been more recently visited by the natives than upon our line of march, which perhaps was not to be wondered at, as what could they get to live on out of such a region as we had got into? Probably forty or fifty miles to the south, over the tops of some low ridges, we saw the ascending smoke of spinifex fires, still attended to by the natives; and in the neighbourhood, no doubt, they had some watering places. On our retreat we travelled round the northern face of the hills, upon whose south side we had arrived, in hopes of finding some place having water, where I might form a depot for a few days. By night we could find none, and had to encamp without, either for ourselves or our horses.

The following day seemed foredoomed to be unlucky; it really appeared as though everything must go wrong by a natural law. In the first place, while making a hobble peg, while Carmichael and Robinson were away after the horses, the little piece of wood slipped out of my hand, and the sharp blade of the knife went through the top and nail of my third finger and stuck in the end of my thumb. The cut bled profusely, and it took me till the horses came to sew my mutilated digits up. It was late when we left this waterless spot. As there was a hill with a prepossessing gorge, I left Carmichael and Robinson to bring the horses on, and rode off to see if I could find water there. Though I rode and walked in gullies and gorges, no water was to be found. I then made down to where the horses should have passed along, and found some of them standing with their packs on, in a small bit of open ground, surrounded by dense scrubs, which by chance I came to, and nobody near. I called and waited, and at last Mr. Carmichael came and told me that when he and Robinson debouched with the horses on this little open space, they found that two of the animals were missing, and that Robinson had gone to pick up their tracks. The horse carrying my papers and instruments was one of the truants. Robinson soon returned, not having found the track. Neither of them could tell when they saw the horses last. I sent Mr. Carmichael to another hill two or three miles away, that we had passed, but not inspected yesterday, to search for water, while Robinson and I looked for the missing horses. And lest any more should retreat during our absence, we tied them up in two mobs. Robinson tied his lot up near a small rock. We then separately made sweeps round, returning to the horses on the opposite side, without success. We then went again in company, and again on opposite sides singly, but neither tracks nor horses could be found. Five hours had now elapsed since I first heard of their absence. I determined to make one more circuit beyond any we had already taken, so as to include the spot we had camped at; this occupied a couple of hours. When I returned I was surprised to hear that Robinson had found the horses in a small but extra dense bunch of scrub not twenty yards from the spot where he had tied his horses up. While I was away he had gone on top of the little stony eminence close by, and from its summit had obtained a bird's-eye view of the ground below, and thus perceived the two animals, which had never been absent at all. It seemed strange to me that I could not find their tracks, but the reason was there were no tracks to find. I took it for granted when Carmichael told me of their absence that they were absent, but he and Robinson were both mistaken.
