The Cooper is known in times of flood to reach a width of between forty and fifty miles, the whole valley being inundated. Floods may surround a traveller while not a drop of local rain may fall, and had the members of this expedition perished in any other way, some remains of iron pack-saddle frames, horns, bones, skulls, firearms, and other articles must have been found by the native inhabitants who occupied the region, and would long ago have been pointed out by the aborigines to the next comers who invaded their territories. The length of time that animals' bones might remain intact in the open air in Australia is exemplified by the fact that in 1870, John Forrest found the skull of a horse in one of Eyre's camps on the cliffs of the south coast thirty years after it was left there by Eyre. Forrest carried the skull to Adelaide. I argue, therefore, that if Leichhardt's animals and equipment had not been buried by a flood, some remains must have been since found, for it is impossible, if such things were above ground that they could escape the lynx-like glances of Australian aboriginals, whose wonderful visual powers are unsurpassed among mankind. Everybody and everything must have been swallowed in a cataclysm and buried deep and sure in the mud and slime of a flood.

The New South Wales Government made praiseworthy efforts to rescue the missing traveller. About a year after Leichhardt visited Port Essington, the Government abandoned the settlement, and the prevailing opinion in the colony of New South Wales at that time was, that Leichhardt had not been able to reach Eyre's Creek, but had been forced up north, from his intended route, the inland-sea theory still prevailing, and that he had probably returned to the old settlement for relief. Therefore, when he had been absent two years, the Government despatched a schooner to the abandoned place. The master of the vessel saw several of the half-civilised natives, who well remembered Leichhardt's arrival there, but he had not returned. The natives promised the master to take the greatest care of him should he again appear, but it is needless to say he was seen no more. The Government were very solicitous about him, and when he had been absent four years, Mr. Hovendon Heley was sent away with an outfit of pack-horses and six or seven men, to endeavour to trace him. This expedition seems to have wandered about for several months, and discovered, as Mr. Heley states, two marked trees branded exactly alike, namely L over XVA, and each spot where these existed is minutely described. There was at each, a water-hole, upon the bank of which the camp was situated; at each camp a marked tree was found branded alike; at each, the frame of a tent was left standing; at each, some logs had been laid down to place the stores and keep them from damp. The two places as described appear so identical that it seems impossible to think otherwise than that Heley and his party arrived twice at the same place without knowing it. The tree or trees were found on a watercourse, or courses, near the head of the Warrego River, in Queensland. The above was all the information gained by this expedition. A subsequent search expedition was sent out in 1858, under Augustus Gregory; this I shall place in its chronological order. Kennedy, a companion of Sir Thomas Mitchell into Tropical Australia in 1845, next enters the field. He went to trace Mitchell's Victoria River or Barcoo, but finding it turned southwards and broke into many channels, he abandoned it, and on his return journey discovered the Warrego River, which may be termed the Murrumbidgee of Queensland. On a second expedition, in 1848, Kennedy started from Moreton Bay to penetrate and explore the country of the long peninsula, which runs up northward between the Gulf of Carpentaria and the Pacific Ocean, and ends at Cape York, the northernmost point of Australia in Torres Straits. From this disastrous expedition he never returned. He was starved, ill, fatigued, hunted by remorseless aborigines for days, and finally speared to death by the natives of Cape York, when almost within sight of his goal, where a vessel was waiting to succour him and all his party. Only a black boy named Jacky Jacky was with him. After Kennedy's death Jacky buried all his papers in a hollow tree, and for a couple of days he eluded his pursuers, until, reaching the spot where his master had told him the vessel would be, he ran yelling down to the beach, followed by a crowd of murderous savages. By the luckiest chance a boat happened to be at the beach, and the officers and crew rescued the boy. The following day a party led by Jacky returned to where poor Kennedy lay, and they buried him. They obtained his books and maps from the tree where Jacky had hidden them. The narrative of this expedition is heart-rending. Of the whole number of the whites, namely seven, two only were rescued by the vessel at a place where Kennedy had formed a depot on the coast, and left four men.

With Captain Roe, a companion of King's, with whom he was speared and nearly killed by the natives of Goulburn Island, in 1820, and who afterwards became Surveyor-General of the colony of Western Australia, the list of Australia's early explorers may be said to close, although I should remark that Augustus Gregory was a West Australian explorer as early as the year 1846. Captain Roe conducted the most extensive inland exploration of Western Australia at that day, in 1848. No works of fiction can excel, or indeed equal, in romantic and heart-stirring interest the volumes, worthy to be written in letters of gold, which record the deeds and the sufferings of these noble toilers in the dim and distant field of discovery afforded by the Australasian continent and its vast islands. It would be well if those works were read by the present generation as eagerly as the imaginary tales of adventure which, while they appeal to no real sentiment, and convey no solid information, cannot compete for a moment with those sublime records of what has been dared, done, and suffered, at the call of duty, and for the sake of human interests by men who have really lived and died. I do not say that all works of fiction are entirely without interest to the human imagination, or that writers of some of these works are not clever, for in one sense they certainly are, and that is, in only writing of horrors that never occurred, without going through the preliminary agony of a practical realisation of the dangers they so graphically describe, and from which, perhaps, they might be the very first to flee, though their heroes are made to appear nothing less than demigods. Strange as it may appear, it seems because the tales of Australian travel and self-devotion are true, that they attract but little notice, for were the narratives of the explorers not true we might become the most renowned novelists the world has ever known. Again, Australian geography, as explained in the works of Australian exploration, might be called an unlearned study. Let me ask how many boys out of a hundred in Australia, or England either, have ever read Sturt or Mitchell, Eyre, Leichhardt, Grey, or Stuart. It is possible a few may have read Cook's voyages, because they appear more national, but who has read Flinders, King, or Stokes? Is it because these narratives are Australian and true that they are not worthy of attention?

Having well-nigh exhausted the list of the early explorers in Australia, it is necessary now to turn to a more modern school. I must admit that in the works of this second section, with a few exceptions, such stirring narratives as those of the older travellers cannot be found. Nevertheless, considerable interest must still attach to them, as they in reality carry on the burning torch which will not be consumed until by its light the whole of Australia stands revealed.

The modern explorers are of a different class, and perhaps of one not so high as their predecessors. By this remark I do not mean anything invidious, and if any of the moderns are correctly to be classed with the ancients, the Brothers Gregory must be spoken of next, as being the fittest to head a secondary list. Augustus Gregory was in the West Australian field of discovery in 1846. He was a great mechanical, as well as a geographical, discoverer, for to him we are indebted for our modern horses' pack-saddles in lieu of the dreadful old English sumpter horse furniture that went by that name; he also invented a new kind of compass known as Gregory's Patent, unequalled for steering on horseback, and through dense scrubs where an ordinary compass would be almost useless, while steering on camels in dense scrubs, on a given bearing, without a Gregory would be next to impossible; it would be far easier indeed, if not absolutely necessary, to walk and lead them, which has to be done in almost all camel countries.

In 1854 Austin made a lengthened journey to the east and northwards, from the old settled places of Western Australia, and in 1856 Augustus Gregory conducted the North Australian Expedition, fitted out under the auspices of the Royal Geographical Society of London. Landing at Stokes's Treachery Bay, Gregory and his brother Frank explored Stokes's Victoria River to its sources, and found another watercourse, whose waters, running inland, somewhat revived the old theory of the inland sea. Upon tracing this river, which he named Sturt's Creek, after the father of Australian exploration, it was found to exhaust itself in a circular basin, which was named Termination Lake. Retracing the creek to where the depot was situated, the party travelled across a stretch of unknown country for some two hundred miles, and striking Leichhardt's Port Essington track on Leichhardt's Roper River, his route was followed too closely for hundreds of miles until civilisation was reached. My friend Baron von Mueller accompanied this expedition as botanist, naturalist, surgeon and physician.

Soon after his return from his northern expedition, Gregory was despatched in 1858 by the Government of New South Wales to search again for the lost explorer Leichhardt, who had then been missing ten years. This expedition resulted in little or nothing, as far as its main object was concerned, one or two trees, marked L, on the Barcoo and lower end of the Thompson, was all it discovered; but, geographically, it settled the question of the course of the Barcoo, or Mitchell's Victoria, which Gregory followed past Kennedy's farthest point, and traced until he found it identical with Sturt's Cooper's Creek. He described it as being of enormous width in times of flood, and two of Sturt's horses, abandoned since 1845, were seen but left uncaptured. Sturt's Strezletki Creek in South Australian territory was then followed. This peculiar watercourse branches out from the Cooper and runs in a south-south-west direction. It brought Gregory safely to the northern settlements of South Australia. The fruitless search for it, however, was one of the main causes of the death of Burke and Wills in 1861. This was Gregory's final attempt; he accepted the position of Surveyor-General of Queensland, and his labours as an explorer terminated. His journals are characterised by a brevity that is not the soul of wit, he appearing to grudge to others the information he had obtained at the expense of great endurance, hardihood, knowledge, and judgment. Gregory was probably the closest observer of all the explorers, except Mitchell, and an advanced geologist.

In 1858 a new aspirant for geographical honours appeared on the field in the person of John McDouall Stuart, of South Australia, who, as before mentioned, had formerly been a member of Captain Sturt's Central Australian expedition in 1843-5 as draftsman and surveyor. Stuart's object was to cross the continent, almost in its greatest width, from south to north; and this he eventually accomplished. After three attempts he finally reached the north coast in 1862, his rival Burke having been the first to do so. Stuart might have been first, but he seems to have under-valued his rival, and wasted time in returning and refitting when he might have performed the feat in two if not one journey; for he discovered a well-watered country the whole way, and his route is now mainly the South Australian Transcontinental Telegraph Line, though it must be remembered that Stuart had something like fifteen hundred miles of unknown country in front of him to explore, while Burke and Wills had scarcely six. Stuart also conducted some minor explorations before he undertook his greater one. He and McKinlay were South Australia's heroes, and are still venerated there accordingly. He died in England not long after the completion of his last expedition.

We now come to probably the most melancholy episode in the long history of Australian exploration, relating to the fate of Burke and Wills. The people and Government of the colony of Victoria determined to despatch an expedition to explore Central Australia, from Sturt's Eyre's Creek to the shores of the Gulf of Carpentaria at the mouth of the Albert River of Stokes's, a distance in a straight line of not more than six hundred miles; and as everything that Victoria undertakes must always be on the grandest scale, so was this. One colonist gave £1000; £4000 more was subscribed, and then the Government took the matter in hand to fit out the Victorian Exploring Expedition. Camels were specially imported from India, and everything was done to ensure success; when I say everything, I mean all but the principal thing—the leader was the wrong man. He knew nothing of bush life or bushmanship, navigation, or any art of travel. Robert O'Hara Burke was brave, no doubt, but so hopelessly ignorant of what he was undertaking, that it would have been the greatest wonder if he had returned alive to civilisation. He was accompanied by a young man named Wills as surveyor and observer; he alone kept a diary, and from his own statements therein he was frequently more than a hundred miles out of his reckoning. That, however, did not cause his or Burke's death; what really did so was bad management. The money this expedition cost, variously estimated at from £40,000 to £60,000, was almost thrown away, for the map of the route of the expedition was incorrect and unreliable, and Wills's journal of no geographical value, except that it showed they had no difficulty with regard to water. The expedition was, however, successful in so far that Burke crossed Australia from south to north before Stuart, and was the first traveller who had done so. Burke and Wills both died upon Cooper's Creek after their return from Carpentaria upon the field of their renown. Charles Gray, one of the party, died, or was killed, a day or two before returning thither, and John King, the sole survivor, was rescued by Alfred Howitt. Burke's and Stuart's lines of travel, though both pushing from south to north, were separated by a distance of over 400 miles in longitude. These travellers, or heroes I suppose I ought to call them, were neither explorers nor bushmen, but they were brave and undaunted, and they died in the cause they had undertaken.

When it became certain in Melbourne that some mishap must have occurred to these adventurers, Victoria, South Australia, and Queensland each sent out relief parties. South Australia sent John McKinlay, who found Gray's grave, and afterwards made a long exploration to Carpentaria, where, not finding any vessel as he expected, he had an arduous struggle to reach a Queensland cattle station near Port Dennison on the eastern coast. Queensland sent Landsborough by sea to Carpentaria, where he was landed and left to live or die as he might, though of course he had a proper equipment of horses, men, and gear. He followed up the Flinders River of Stokes, had a fine country to traverse; got on to the head of the Warrego, and finally on to the Darling River in New South Wales. He came across no traces whatever of Burke. Victoria sent a relief expedition under Walker, with several Queensland black troopers. Walker, crossing the lower Barcoo, found a tree of Leichhardt's marked L, being the most westerly known. Walker arrived at Carpentaria without seeing any traces of the missing Burke and Wills; but at the mouth of the Albert River met the master of the vessel that had conveyed Landsborough; the master had seen or heard nothing of Burke. Another expedition fitted out by Victoria, and called the Victorian Contingent Relief Expedition, was placed under the command of Alfred Howitt in 1861. At this time a friend of mine, named Conn, and I were out exploring for pastoral runs, and were in retreat upon the Darling, when we met Howitt going out. When farther north I repeatedly urged my companion to visit the Cooper, from which we were then only eighty or ninety miles away, in vain. I urged how we might succour some, if not all, of the wanderers. Had we done so we should have found and rescued King, and we might have been in time to save Burke and Wills also; but Conn would not agree to go. It is true we were nearly starved as it was, and might have been entirely starved had we gone there, but by good fortune we met and shot a stray bullock that had wandered from the Darling, and this happy chance saved our lives. I may here remark that poor Conn and two other exploring comrades of those days, named Curlewis and McCulloch, were all subsequently, not only killed but partly eaten by the wild natives of Australia—Conn in a place near Cooktown on the Queensland coast, and Curlewis and McCulloch on the Paroo River in New South Wales in 1862. When we were together we had many very narrow escapes from death, and I have had several similar experiences since those days. Howitt on his arrival at Cooper's Creek was informed by the natives that a white man was alive with them, and thus John King, the sole survivor, was rescued.
