We are now approaching a period when the exploration of the continent was an object of absorbing interest to all the settlements fast growing into importance on the southern and eastern coasts. Three explorers, who may be classed as the greatest, the most successful, and the one whose star that rose so bright at this time was doomed to set in misfortune, were in the field at the same time. Charles Sturt, fated once more to meet and be defeated (if such a gallant struggle can be called defeat) by the inexorable desert and the stern denial of its climate. Thomas Mitchell, again the favoured of fortune, to wend his way by well-watered streams and grassy downs and plains. And Ludwig Leichhardt, to accomplish his one great journey through the country permeated by the rivers of the eastern and northern coast. But before starting in company with these deathless names, we must, for a while, return to Lake Torrens. Eyre, it will be remembered, reached, after much labour, a hill to the north east at the termination of the range, which he named Mount Hopeless. From the view he obtained from the summit, he concluded that Lake Torrens completely enclosed the northern portion of the province of South Australia; and in fact that the province had once been an island, as the low-lying plains probably joined the flat country west of the Darling. In 1843, the then Surveyor-General of the colony, Captain Frome, started to the north to ascertain as much of this mysterious lake as he could. He reached Mount Serle, and found the dry bed of the great lake to the eastward, as described by Eyre, but discovered an error of thirty miles in its position, Eyre having placed it too far to the eastward. Further north than this, Frome did not proceed; on his way back lie made two excursions to the eastward, but found nothing but sterile and unpromising country. He confirmed then, the existence of a lake to the eastward of the southern point of Lake Torrens, but his explorations did not go far to determine the identity of the two, nor their uninterrupted continuity. Prior to this, a series of explorations, followed by settlement, had taken place east and west of Eyre's track, between Adelaide and the head of Spencer's Gulf. One promising expedition was nipped in the bud by the accidental death of the leader, a rising young explorer, who had already won his spurs in opening up fresh country in the province. This was Mr. J. Horrocks, who formed a plan for travelling up the western side of Lake Torrens, and then, if possible, making westward and trying to reach the Swan River. This expedition is especially noteworthy as being the first one in which a camel was made use of, and to Horrocks, is due the credit of first introducing these animals as baggage carriers. When at the head of the Gulf, and about to grapple with the unknown land to the west, his gun accidentally went off, and he received the charge in his face. He
