Whilst the agriculturists have been so earnest in the development of the productive powers of the colony, another class of its inhabitants were paying equal attention to its pastoral interests. The establishment of stock stations over its surface followed its occupation, and a mild climate and nutritive herbage equally contributed to the increase of cattle and sheep that had been introduced. In 1844 the number of sheep assessed was 355,700, in the following year that number had increased to 480,669, or an addition of 120,000. At the present moment there cannot be far short of a million of sheep in the province, with an increase of 200,000 annually, at a moderate computation. The number of other kinds of stock in the possession of the settlers, at the close of last year, was as follows:--of cattle, 70,000; 30,000 having been imported during the two previous years from New South Wales. The number of horses was estimated at 5000, and of other smaller stock, as pigs and goats, there were supposed to be more than 20,000.

It is impossible to contemplate such a prosperous state of things in a colony that has only just completed the eleventh year of its existence, without feeling satisfied that some unusually favourable circumstances had brought it about. Had South Australia been as distant from the older colonies on the continent as Swan River, the amount of stock she would have possessed in an equal length of time, could not have amounted to a tenth of what they now number. It is to the discovery of the Darling and the Murray that South Australia owes the superabundance of her flocks and herds, and in that superabundance the full and complete establishment of her pastoral interests. I stated in the course of my preliminary observations on the progress of Australian discovery, that when I was toiling down those rivers, with wide spread deserts on either side of me, I had little idea for what purposes my footsteps had been directed into the interior of the Australian Continent. If I ever entertained even a distant hope that the hilly country from which I turned back at the termination of the Murray, after having floated on its broad waters for eighty-eight days, might ever be occupied, I certainly never hoped that the discoveries I was then making would one day or other prove of advantage to many a friend, and that I was marking the way for thousands of herds and flocks, the surplus stock of New South Wales, to pass into the province of South Australia.

If then such consequences have resulted from enterprises, apparently of almost as hopeless a character as the one from which I have so recently returned, why, I would ask, should I despair, as to its one day or other being instrumental in benefiting my countrymen. There may yet be that in the womb of time which shall repay me for all I suffered in the performance of that dreary task--when I shall have it in my power to say, that I so far led the way across the continent as to make the remainder of easy attainment, and under the guidance and blessing of Providence have been mainly instrumental in establishing a line of communication between its northern and southern coasts. I see no reason why I should despair that such may one day be the case. The road to the point which may be termed my farthest north is clear before the explorer. That point gained, less probably than 200 miles--a week's journey with horses less jaded than mine unfortunately were, and with strength less reduced--would place him beyond the limits of that fearful desert, and crown his labours with success. I believe that I could, on my old route, make the north coast of Australia, to the westward of the Gulf of Carpentaria, before any party from Moreton Bay. If it is asked what practical good I should expect to result from such an undertaking, I would observe, that nothing would sooner tend to establish an intercourse with the inhabitants of the Malay archipelago, than the barter of cattle and sheep, that in truth there is no knowing what the ultimate results would be. The Malays who visit the northern coasts of Australia to collect the sea slug, have little inducement to keep up an intercourse with our settlements in Torres Straits, but there can be no doubt of their readiness to enter into commercial intercourse with us, which, if Torres Straits are to be navigated by steamers, would be doubly important.

When the stock from New South Wales was first brought down the Murray, the journey occupied from three to four months. Latterly it did not take half that time. In less than fifty days, from the Murray, on his way to the north, the stock-holder would find that he had passed the centre, and an equal number of days from that point would, it appears to me, take him to his journey's end. This, however, would depend on the nature of the country beyond where it is at present known, and the nature of the season during which it was undertaken, but experience alone, as in the instance of the journey down the Murray, would be the best guide and the best instructor.

In the early part of the year 1840, I had occasion to address a number of the colonists at the conclusion of a public entertainment and availed myself of the opportunity to state that whatever prospects of success the pastoral capabilities of the province appeared to hold out, I felt assured it was to the mountains, the colonists would have to look for their future wealth, for that no one who pretended to the eye of a geologist could cross them as I had done, without the conviction that they abounded in mineral veins. There is something, in truth, in the outline and form of the Mount Lofty chain that betrays its character. Rounded spurs, of very peculiar form, having deep valleys on either side, come down from the main range, the general outline of which bears a strong resemblance to that of the Ural chain.

In the year 1843, the first discovery of copper was made, but even this was scarcely sufficient to rouse the colonists to a full sense of its importance, and it was only by degrees, as other mines were successively discovered, that the spirit of speculation burst forth, and the energies of the settlers were turned for a time from their legitimate channels. A short time before this, their circumstances had been reduced to the lowest ebb. There was no sale for agricultural produce, no demand for labour, the goods in the shops of the tradesmen remained unsold, and the most painful sacrifices of property were daily made at the auction mart. The amount of distress indeed was very great and severe, but such a state of things was naturally to be expected from the change that had taken place in the monetary affairs of the province. It was a change however which few anticipated, and for which few therefore were prepared.

It is a painful task to advert to past scenes of difficulty and distress, such at least I feel it to be, more especially where there is no immediate object to be gained by a reference to them; let me therefore turn from any inquiry into the causes which plunged South Australia into difficulties that threatened to overwhelm her, to those which raised her from them.

Notwithstanding the spirit and firmness with which the colonists bore their reverses, there could not but be a gloom over the community where every thing seemed to be on the brink of ruin. Men's minds became depressed when they saw no relief in the present, and no hope in the future. But Time, with a rapid wing, brought about changes that appear permanently to have altered the circumstances of the colony, and to have placed it at once as one of the most flourishing of the British possessions. The first circumstance, I have understood, which partially cheered the drooping spirits of the settlers, was a slight rise in the price of wool, in the year I have mentioned. The discovery of the mines following soon upon this, the sun of prosperity burst at once upon the province, and gladdened every heart. From this period, mine after mine of copper and lead continued to be discovered. Every valley and hill-top was searched for hidden treasures, and the whole energies of the colonists seemed to be turned to this new source of wealth. I was absent in the interior when the Burra Burra mine was secured, but the excitement it created had not subsided when I reached Adelaide.

I do not know whether the presence of mineral veins is indicated in other countries as in South Australia by means of surface deposits. The opinion I formed that ores would be discovered in the Mount Lofty ranges did not rest upon the discovery of any such deposit myself, but on the peculiar form of the hills, which appeared to me to have settled into their present state from one of extreme fusion. The direction of the ranges being from north to south, these deposits lie also in the same direction. Those of iron are greater than those of copper, and it is impossible to describe the appearance of the huge clean masses of which they are composed. They look indeed like immense blocks, that had only just passed from the forge. The deposits at the Burra Burra amounted, I believe, to some thousand tons, and led to the impression that where so great a quantity of surface ore existed, but little would be found beneath. In working this gigantic mine, however, it has proved otherwise. I was informed by one of the shareholders just before I left the colony, that it took three hours and three-quarters to go through the shafts and galleries of the mine. Some of the latter are cut through solid blocks of ore, which glitter like gold where the hammer or chisel has struck the rock, as you pass with a candle along them.

It would be out of place in me, nor indeed would it interest my readers, were I to enter into a statistical account of the profits of the Burra Burra mine. A general notice will convey every necessary information on that head, and enable the public to judge as well of its value and importance as if I entered into minuter details. It will give the reader some idea of the scene of bustle and activity the Burra mine and road must present, and the very great amount of labour it requires.
