On the morning of the 14th Mr. Browne and I mounted our horses, and left the camp at 9 a.m., followed by the men I had selected, and crossing the grassy plain in a N.W. direction, soon found ourselves amidst sand hills and scrub.
As I have stated I had determined to preserve a course of 45 degrees to the west of north, or in other words a north-west course, but the reader will readily believe that in such a country I had no distant object on which to rely. We were therefore obliged to take fresh bearings with great precision from almost every sand-hill, for on the correctness of these bearings, together with our latitude, we had to depend for our true position. We were indeed like a ship at sea, without the advantage of a steady compass.
Throughout the whole day of our departure from the camp we traversed a better country than that between it and Lake Torrens, insomuch that there was more grass. Sand ridges and flats succeeded each other, but the former were not so broken and precipitous or the latter so barren, as on our line to the westward, and about four miles from the camp we passed a pool of water to our right. At five miles we observed a new melaleuca, similar to the one I had remarked when to the north with Joseph, growing on the skirts of the flats, but the shrubs for the most part consisted of hakea and mimosae with geum and many other minor plants. For a time the ridges were smooth on their sides, and a quantity of young green grass was springing up on them. At nine miles we crossed some stony plains, and halted after a ride of 26 miles without water.
On the 15th a strong and bitterly cold wind blew from the westward as we passed through a country differing in no material respect from that of the day before. Spinifex generally covered the sand ridges, which looked like ocean swells rising before us, and many were of considerable height. At six miles we came to a small pool of water, where we breakfasted. On leaving this we dug a hole and let the remainder of the water into it, in the hope of its longer continuance, and halted after a long journey in a valley in which there was a kind of watercourse with plenty of water, our latitude being 28 degrees 21 minutes 39 seconds. Before we left this place we cut a deep square hole, into which as before we drained the water, that by diminishing its surface we might prevent the too speedy evaporation of it, in case of our being forced back from the want of water in the interior, since that element was becoming more scarce every day. We saw but little change in the character of the country generally as we rode through it, but observed that it was more open to the right, in which direction we passed several extensive plains. There were heaps of small pebbles also of ironstone and quartz on some of the flats we crossed. We halted at the foot of a sand hill, where there was a good deal of grass, after a vain search for water, of which we did not see a drop during the day. The night of the 17th, like the preceding one, was bitterly cold, with the wind at S.W. During the early part of this day we passed over high ridges of sand, thickly covered with spinifex, and a new polygonum, but subsequently crossed some flats of much greater extent than usual, and of much better soil, but the country again fell off in quality and appearance, although on the whole the tract we had crossed on our present journey was certainly better than that we traversed in going to Lake Torrens. We halted rather earlier than usual, at a creek containing a long pond of water between two and three feet deep. The ground near it was barren, if I except the polygonum that was growing near it. The horses however found a sufficiency to eat, and we were prevented the necessity of digging at this point, in consequence of the depth of the water. We observed some fossil limestone cropping out of the ground in several places as we rode along, and the flats were on many parts covered with small rounded nodules of lime, similar to those I have noticed as being strewed over the fossil cliffs of the Murray. It appeared to me as I rode over some of the flats that the drainage was to the south, but it was exceedingly difficult in so level and monotonous a region to form a satisfactory opinion. We saw several emus in the course of the day, and a solitary crow, but scarcely any other of the feathered tribe. There was an universal sameness in the vegetation, if I except the angophora, growing on the sand hills and superseding the acacia.
On the 18th the morning was very cold, with the wind at cast, and a cloudy sky. We started at eight; and after crossing three very high sand ridges, descended into a plain of about three miles in breadth, extending on either hand to the north and south for many miles. At the further extremity of this plain we observed a line of box-trees, lying, or rather stretching, right across our course; but as they were thicker to the S.W. than at the point towards which we were riding, I sent Flood to examine the plain in that direction. In the mean time Mr. Browne and I rode quietly on; and on arriving at the trees, found that they were growing in the broad bed of a creek, and were overhanging a beautiful sheet of water, such as we had not seen for many a day. It was altogether too important a feature to pass without further examination; I therefore crossed, and halted on its west bank, and as soon as Flood returned, (who had not seen any water,) but had ascertained that just below the trees, the creek spreads over the plain, I sent him with Mr. Browne to trace it up northward, the fall of the country apparently being from that point. In the meantime we unloaded the horses, and put them out on better grass than they had had for some time. On the opposite side of the creek, and somewhat above us, there were two huts, and the claws of crayfish were scattered about near them. There were also a few wild fowl and Haemantopus sitting on the water, either unconscious of or indifferent to our presence. This fine sheet of water was more than 60 yards broad by about 120 long, but, as far as we could judge, it was shallow.
Mr. Browne returned to me in about three hours, having traced the creek upwards until he lost its channel, as Flood had done on a large plain, that extended northwards to the horizon. He observed the country was very open in that direction, and had passed another pond of water, deeper but not so large as that at which we had stopped, and surprised an old native in his hut with two of his wives, from whom he learnt that there were both hills and fish to the north.
Whilst Mr. Browne was away, I debated within myself whether or not to turn from the course on which I had been running to trace this creek up. The surface water was so very scarce, that I doubted the possibility of our getting on; but was reluctant to deviate from the line on which I had determined to penetrate, and I think that, generally, one seldom gains anything in so doing. From Mr. Browne's account of the creek, its character appeared to be doubtful, so that I no longer hesitated on my onward course; but we remained stationary for the remainder of the day.
The evening of this day was beautifully fine, and during it many flights of parrots and pigeons came to the water. Of the latter we shot several, but they were very wild and wary. There was on the opposite side of the creek a long grassy flat, with box-trees growing on it, together with a new Bauhinia, which we saw here for the first time. On this grassy flat there were a number of the water-hens we had noticed on the little fresh-water creek near Lake Torrens. These birds were running about like fowls all over the grass, but although they had been so tame as to occupy the gardens and to run about the streets of Adelaide, they were now wild enough.
Mr. Browne remarked that the females he had seen were, contrary to general custom as regards that sex, deficient in the two front teeth of the upper jaw, but that the teeth of the man were entire, and that he was not otherwise disfigured. I was anxious to have seen these natives, and, as their hut was not very far from us, we walked to it in the cool of the afternoon, but they had left, and apparently gone to the N.E.; we found some mussel shells amongst the embers of some old fire near it. Our latitude at this point was 28 degrees 3 minutes S., at a distance of 86 miles from the Park.
We left on the morning of the 20th at an early hour, and after crossing that portion of the plain lying to the westward, ascended a small conical sand hill, that rose above the otherwise level summit of the ridge. From this little sand hill we had our anticipations confirmed as to the low nature of the country to the north as a medium point, but observing another and a much higher point to the westward, we went to, and found that the view extended to a much greater distance from it. The country was very depressed, both to the north and northwest. The plains had almost the character of lagoons, since it was evident they were sometimes inundated, from the water mark on the sand hills, by which they were partly separated from one another. Below us, on our course, there was a large plain of about eight miles in breadth; but immediately at the foot of the hill, which was very abrupt (being the terminating point of a sandy ridge of which it was the northern extremity), there was a polygonum flat. We there saw a beautiful parrot, but could not procure it. The plain we next rode across was evidently subject to floods in many parts; the soil was a mixture of sand and clay. There was a good deal of grass here and there upon it, and box-trees stunted in their growth were scattered very sparingly round about; but the country was otherwise denuded of timber. There were large bare patches on the plains, that had been full of water not long before, but too shallow to have lasted long, and were now dry. We found several small pools, however, and halted at one, after a journey of 17 miles, near some gum-trees.
