As was but natural, the construction of the overland telegraph line between Adelaide and Port Darwin led to numbers of short explorations on either side of the line, which considerably added to our knowledge of the interior, but of which no records have been kept.
The establishment of this telegraph line and its maintenance did much towards the settlement of Central Australia. It formed, as it were, a chain of outposts through the heart of the continent, and thereby greatly facilitated the success of many private expeditions undertaken in quest of country for pastoral purposes.
South Australia had served a rough apprenticeship in the cause of exploration, and the experience gained by her pioneers now stood her in good stead in the successful accomplishment of the national work she at this time undertook—the establishment of telegraphic communication with England. Queensland, the youngest colony of the group, was striving very hard to secure the landing of the cable on her shores. Walker, the leader of one of the Burke and Wills search parties, was out examining the country at the back of Rockingham Bay, and marking a telegraph line from there to the mouth of the Norman River, in the Gulf of Carpentaria. South Australia, however, thanks to her energy and superior geographical position, secured the honour; and already the completion of a railway across the country which witnessed the repeated efforts of Stuart is being hastened on.
In Western Australia, in 1864, Hunt made a long excursion to the eastward of York, and travelled for 400 miles over the country lying between the 31st and 32nd parallels. He found nothing to reward him for his trouble—scrub, salt lakes and samphire flats were the same wearisome. repetition.
During the construction of the overland telegraph line it was surmised that such a close examination of the country as would necessarily ensue, might lead to the finding of traces of Leichhardt, if he ever had reached so far on his journey; but none were found. Apparently it suggested an idea to a prisoner in one of the gaols of New South Wales, for he made a statement to the effect that he had been employed as a labourer on the construction of the overland telegraph line, and whilst so engaged had been in the habit of making long excursions into the unexplored territory on either side of the line. During one of these trips he came across some blacks, who informed him that they had an old white man living with their tribe. Hume—which was the name of the hero of this story—professed to have an intimate acquaintance with the habits and customs of the natives, and willingly accompanied them to their camp. Here he found a venerable old white man, who turned out to be Classen—Leichhardt's brother-in-law—and from him Hume learnt that the death of the leader and most of his party happened through a mutiny in the camp, Leichhardt being murdered, and the party then becoming disorganised and lost. This absurd story was repeated so earnestly that inquiries were instituted, and it was found that Hume had really been employed on the telegraph line, and that whilst there he had been absent for some time on one or two occasions.
Hume was interviewed by some gentlemen who were interested in the solution of Leichhardt's fate, and he now added a little additional matter: that on a subsequent visit he found that Classen, rendered restless by the near neighbourhood of the whites, had made an effort to reach them and died in the attempt. This, with a few variations as to the details of the death of Leichhardt, led to Hume being released from gaol for the purpose of leading a party to the spot where Classen had pointed out that he had concealed Leichhardt's journals. But for the tragedy that ended the affair this episode would scarcely be of sufficient importance to insert in the history of explorations. Money having been furnished for the purpose, Hume and two companions started on their search. They reached Thargomindah—then the nucleus of a small township in Western Queensland—and left a station called Nockatunga to make a short cut across some dry country. One man only turned up. He said that they had lost themselves, had separated looking for water, and with much difficulty he reached the station. Search being instituted the dead bodies of Hume and the other man were found, they having perished of thirst. This story was revived many years afterwards by another man, who had lived a good deal on the frontiers of Queensland. According to him, Leichhardt and some of his party died of hunger and thirst, Classen was revived again, and the discoverer stated that he had in his possession a diary and many relics of the explorer. Although expressing his willingness to produce the relics on receiving the promise of an adequate reward, he never did so, and having attained a temporary notoriety, returned to his former obscurity. This may be said to end the rumours of the discovery of Leichhardt's memorials, They served no good end in any way.
John Forrest, of Western Australia, made his first important journey in 1869. It will be remembered that a report had been current for many years amongst the natives of Western Australia, to the effect that a party of white men coming from the east had been murdered by the natives on the shore of an interior salt lake. A Mr. Monger, when out west in search of pastoral country, came across a native who stated that he had been to the place where the murder was committed, had seen the remains, and would lead the party there.
As usual with the Australian natives, his story was most circumstantial. He described the scene of the murder as being in the neighbourhood of a large lake, so large that it looked like the sea, and that the white men were attacked and killed whilst making a damper. These artistic details with which the blacks embellish their narratives, make it very hard to refuse credence to them.
Baron Von Mueller immediately wrote to the Western Australian Government, offering to lead a party there, and ascertain the truth of the report. The Government took the matter up, and made preparations to start an expedition. Von Mueller was, however, prevented by his other engagements from taking charge, and the command was given to Mr. John Forrest, a surveyor.
On the 26th of April, 1869, Forrest and his party reached Yarraging, then the farthest station to the eastward. On the first of May, when camped at a native well, visited by Austin in 1854, Forrest says that he could still distinctly see the tracks of that explorer's horses. Past this spot he fell in with natives, who told him that a large party of men and horses died at a place in a northerly direction, and that a gun belonging to the party was still in the possession of the blacks. On closer examination this story turned out to relate to nine of Mr. Austin's horses poisoned during his expedition. Forrest continued his journey to the eastward, and on the 18th came to a large dry salt lake, which he named Lake Barlee. An attempt to cross this lake resulted in getting the horses bogged, and a good deal of hard work had to be gone through before the packs and horses were once more safe on dry land Lake Barlee was afterwards found to be of great size, extending for more than forty miles to the eastward. The native guide Forrest had with him now became rather doubtful as to the exact position of the spot where he professed to have seen the remains, and Forrest, after some searching, came across a large party of the local inhabitants. But they proved anything but friendly, threw dowaks at the blackfellow, and advised the whites to go away before they were killed. As it was getting dark they adopted this advice, and retreated some five miles and camped, Mr. Monger having unfortunately lost his revolver in the scrub. Next morning they managed to get speech with two of the blacks, who restored the revolver, which they had found, and had been warming at the fire. These men stated that the bones were two days' journey to the north, but they were the bones of horses, not of men, and offered to take the whites there, promising to come to the camp the following day, a promise which was riot kept.
