Part 4 (1/2)
July 8.--Our horses having strayed this morning I sent the native boy to look for them, but as he did not return in a reasonable time, I got anxious and went after him myself, leaving the saddles and provisions at our sleeping place. In about four miles I met the boy returning with the runaways, which had rambled for several miles, though they had abundance of good feed around the camp; fortunately we found every thing safe when we got back, but if any natives had accidentally pa.s.sed that way we should probably have lost everything, and been left in very awkward predicament.
This is a risk I have frequently been obliged to incur, and is one of the inconveniences resulting from so small a number as two travelling alone; it it is not always practicable from want of gra.s.s to tether the horses, and frequently when they are tethered the ropes break, and occasion the necessity of both individuals leaving the encampment to search for them at the same time.
Moving on to the N. W. by N. we pa.s.sed over heavy sandy ridges, with barren red plains between, and in one of the latter we found a puddle of rain water, this upon tasting. I found to be rather saline from the nature of the soil upon which it lay, the horses, however, drank it readily, and we put some in a small keg for ourselves. The only vegetation to be seen consisted of a few small stunted trees and shrubs, and even these as we approached the vicinity of the lake disappeared altogether, and gave place to Salsolaceous plants, the country being open and barren in the extreme.
I found Lake Torrens completely girded by a steep sandy ridge, exactly like the sandy ridges bounding the sea sh.o.r.e, no rocks or stones were visible any where, but many saline coasts peeped out in the outer ridge, and upon descending westerly to its basin, I found the dry bed of the lake coated completely over with a crust of salt, forming one unbroken sheet of pure white, and glittering brilliantly in the sun. On stepping upon this I found that it yielded to the foot, and that below the surface the bed of the lake consisted of a soft mud, and the further we advanced to the westward the more boggy it got, so that at last it became quite impossible to proceed, and I was obliged to return to the outer margin of the lake without ascertaining whether there was water on the surface of its bed further west or not.
The extraordinary deception caused by mirage and refraction, arising from the state of the atmosphere in these regions, makes it almost impossible to believe the evidence of one's own eyesight; but as far as I could judge under these circ.u.mstances, it appeared to me that there was water in the bed of the lake at a distance of four or five miles from where I was, and at this point Lake Torrens was about fifteen or twenty miles across, having high land bounding it to the west, seemingly a continuation of the table land at the head of Spencer's gulf on its western side.
Foiled in the hope of reaching the water, I stood gazing on the dismal prospect before me with feelings of chagrin and gloom. I can hardly say I felt disappointed, for my expectations in this quarter had never been sanguine; but I could not view unmoved, a scene which from its character and extent, I well knew must exercise a great influence over my future plans and hopes: the vast area of the lake was before me interminable as far as the eye could see to the northward, and the country upon its sh.o.r.e, was desolate and forbidding.
It was evident, that I could never hope to take my party across the lake, and it was equally evident, that I should not be able to travel around its sh.o.r.es, from the total absence of all fresh water, gra.s.s, or wood, whilst the very saline nature of the soil in the surrounding country, made even the rain water salt, after lying for an hour or two upon the ground. My only chance of success now lay in the non-termination of Flinders range, and in the prospect it held out to me, that by continuing our course along it we might be able to procure gra.s.s and water in its recesses, until we were either taken beyond Lake Torrens, or led to some practicable opening to the north.
With a heavy heart I turned towards the mountains, and steering N. E. for ten miles, halted at dark, where there was nothing for our horses to eat or drink, and we were consequently obliged to tie them up for the night.
We had still a few oats left and gave each horse three pints. A short time before encamping, I had observed that Lake Torrens was trending more to the eastward, and that when we halted, it was not at any very great distance from us.
July 9.--One of our horses having got loose last night, pulled the cork out of the keg in which was our small stock of the dirty brackish water we had found yesterday, and rolling the keg over, destroyed its contents; we were thus deprived of our breakfasts, and consequently had but little delay in starting. I intended to push on steadily for the hills, but after travelling six miles came to a puddle in the plains, with tolerable gra.s.s around, and at this I halted for the day, to rest the horses. Our lat.i.tude was 31 degrees 25 minutes S. by an alt.i.tude of Arcturus, Mount Eyre then bearing S. 7 degrees E.
July 10.--Our horses being much recruited I altered our course to-day to N. 5 degrees E. being the bearing of the most distant range to the northward, (subsequently named Mount Deception). We pa.s.sed for the first ten miles through an open barren country, but found a puddle at which we watered our horses, and refilled the keg; we then entered heavy ridges of dense red sand lying nearly north and south, and having small barren plains between.
There were a few stunted bushes upon the ridges and occasionally some small straggling pines. Lake Torrens still trended easterly, being occasionally seen from, and sometimes approaching near to our track.
Emerging from the sandy ridges we again entered upon vast level plains covered with rhaG.o.dia. In the midst of these we came to the bed of a large dry watercourse, having good gra.s.s about it, but containing no water. I halted here for the day as our horses were not very thirsty.
Upon examining the bed of the watercourse, I found traces of a rather recent and high flood; much drift being still left upon the bushes where it had been swept by the torrent; I could, however, find no water anywhere.
A great many emus were seen during our ride, and I wounded one with my rifle, but did not get it. We found to-day a description of flower, which I had not seen before, white, and sweetly scented like the hawthorn, growing upon a low p.r.i.c.kly bush near the watercourse.
July 11.--To-day I left our course and rambled up the watercourse to examine its character and search for water, which however I could not find in its channel anywhere. Traces of natives were numerous and recent all the way as we went, till at last we came to where they had encamped the previous night, and where they had left a fire still fresh and burning.
Proceeding onwards we came upon a single native, a female, young, but miserably thin and squalid, fit emblem of the sterility of the country.
We could gain no information from her, she was so much alarmed, but not long after parting with her we came to a puddle of water in the plains, and encamped for the night. Our stage had been a tortuous, but not a long one, and we halted early in the day, the lat.i.tude was 30 degrees 58 minutes S. by an alt.i.tude of the sun at noon.
After taking some refreshment, I walked to a rise about three miles off at N. 40 degrees E. from which I took several bearings, and among them I set Mount Deception at N. 25 degrees W., I then examined several of the gorges between the front hills, where the banks were broken away, and to my great dismay found in all of them salt mixed with the sand, the clay, and even the rocks; whilst in the bed of the watercourse, the salt water tea-tree was making its appearance, a shrub I had never before seen under Flinders range, and one which never grows where the soil is not of a very saline nature, and generally only where the water is too brackish for use.
The beds of the watercourses were in some places quite white and glazed with encrustations of salt, where the rains had lodged, and the water had evaporated. Some of the cliffs which I examined presented sections of 40 and 50 feet perpendicular height, in which layers of salt were embedded from the very top to the bottom.
In such a country, what accommodation could I expect, or what hopes could I entertain for the future, when the very water shed from the clouds would not be drinkable after remaining a few hours on the ground?
Whichever way I turned myself, to the West, to the East, or the North, nothing but difficulties met my view.
In one direction was an impracticable lake, skirted by heavy and scrubby sand ridges; in another, a desert of bare and barren plains; and in a third, a range of inhospitable rocks. The very stones lying upon the hills looked like the scorched and withered scoria of a volcanic region; and even the natives, judging from the specimen I had seen to-day, partook of the general misery and wretchedness of the place.
My heart sank within me when I reflected upon the gradual but too obvious change that had taken place in the character of the country for the worse, and when I considered that for some days past we had been entirely dependent for our supply of water upon the little puddles that had been left on the plains by the rain, and which two or three more days would completely dry up. Under circ.u.mstances so unpropitious, I had many misgivings, and the contemplation of our future prospect became a subject of painful anxiety.
July 12.--We moved away early, steering for Mount Deception. Near its base, and emanating from it, we crossed the dry bed of a very large watercourse, more resembling that of a river in character, its channel being wide, deep, and well-defined, and lined with the salt-water tea-tree; whilst its course was marked by very large, green looking gum-trees, the bed consisted of an earthy, micaceous slate of a reddish colour, and in very minute particles, almost in some places as fine as sand, but we could find no water in it anywhere.
The range in which this watercourse has its source, is of the same slaty rock, and very rugged; it could not be less than 3,000 feet in elevation, and its summit was only attainable by winding along the steep and stony ridges that led round the deep gorges and ravines by which it was surrounded.
From the top the view was extensive and unsatisfactory. Lake Torrens appearing as large and mysterious as ever, and bearing in its most northerly extreme visible W. 22 degrees N. To the north was a low level cheerless waste, and to the east Flinders range trending more easterly, and then sweeping back to N. 28 degrees W. but its appearance seemed to be changing and its character altering; the ranges struck me as being more separated by ridges, with barren flats and valleys between, among which winding to the N. W. were many large and deep watercourses, but which when traced up, often for many miles, I found to emanate from gorges of the hills, and to have neither water nor springs in them.
