In taking leave of this explorer, another short extract from his journal will best show the character of the man of whom Australians should be so justly proud. "Circumstances may yet arise to give a value to my recent labours, and my name may be remembered by after generations in Australia, as the first who tried to penetrate to its centre. If I failed in that great object, I have one consolation in the retrospect of my past services. My path amongst savage tribes has been a bloodless one, not but that I have often been placed in situations of risk and danger, when I might have been justified in shedding blood, but I trust I have ever made allowances for human timidity, and respected the customs of the rudest people." The next prominent figure in the history of this time is Leichhardt, whose unknown fate has been the cause of so much sentiment clinging about his name. Dr. Ludwig Leichhardt arrived in the colony in 1842, and travelled to Moreton Bay overland, where he occupied himself for two years in short excursions in the neighbourhood, pursuing his favourite study of physical science. Leichhardt was born in Beskow, near Berlin, and studied in Berlin. Through a neglect, he was excluded from the one-year military service, and thereby induced to escape from the three-yearly service. The consequence was, that he was pursued as a deserter and sentenced IN CONTUMACIAM. Afterwards, Alexander Von Humboldt succeeded, by representing his services to science on his first expedition in Australia, in obtaining a pardon from the King. By a Cabinet order Leichhardt received permission to return to Prussia unpunished. This order, whether of any value to Leichhardt or not, came too late. When it arrived in Australia he had already started on his last expedition. When the expedition was projected from Fort Bourke, on the Darling, to the Gulf of Carpentaria or Port Essington, he was desirous of securing the position of naturalist thereon; the delay in the starting of it disappointed him, and he made up his mind to attempt one on his own account, a project in which he received little encouragement. He persevered, however, and eking out his own resources, by means of private contributions he managed to get a party together, and on the 1st of October, 1844, he left Jimbour, on the Darling Downs, with six whites and two blacks, 17 horses, 16 head of cattle, and four kangaroo dogs; his other supplies being proportionately meagre. As Leichhardt's journal of this trip has been so widely read, and as it does not possess the same striking interest as that of Sturt's, from the more accessible nature of the country travelled through, and the absence of the constantly threatening dangers overhanging both Sturt and Eyre, a shorter account of the progress of the expedition will be found most acceptable.
