Leichhardt's journey from Moreton Bay to Port Essington furnished the first knowledge we had of the capabilities of North Queensland. It was the turning of its first leaf of history, for his journey was for the greater part through the territory now comprised within its boundaries. The record of his trials, hardships, and endurance, will stand unequalled among all histories of explorations in any part of Australia. Mr. John Roper, who was badly speared in the night attack by blacks and lost the use of one eye afterwards, died a few years ago at Merriwa, New South Wales, and was the last survivor of Leichhardt's first trip to Port Essington. On a subsequent exploring trip, in which he intended to cross Australia from east to west, Leichhardt and his party disappeared, and no definite information has ever been forthcoming as to the fate that overtook them. On this occasion he started from the Darling Downs, and his companions were Hentig, Classan, Donald Stuart, Kelly, and two natives, Womai and Billy. His last letter is dated April 4th, 1848, from Macpherson's station--Coogoon, beyond Mount Abundance, situated about six miles west of the present town of Roma. Traces have been discovered of their journey through a part of the Flinders River country. Two horses found by Duncan Macintyre on the Dugald, a branch of the Cloncurry, about 1860, were identified as having belonged to Leichhardt's expedition, and some traces were discovered by A. C. Gregory in latitude 24 deg. south, consisting of a marked tree at one of his old camps. These form the only records we possess of the ill-fated travellers. Drought may have split his party up in the desert interior, and, disorganised and scattered, they would fall an easy prey to thirst and delirium, for so soon does extreme thirst in a hot and dry climate demoralise the strongest men, that hope is lost even in a few hours, and delirium sets in. People thus distracted, lie down under the nearest bush to die, after having wandered to every point of the compass in search of water until their strength fails. On the other hand, the party may have been destroyed by flood, by hunger, or by the attacks of hostile natives, a mutiny may have broken out and the party, split up into fragments, may have wandered by devious paths and perished in detail. Many expeditions were sent out in search of the lost explorers, and although not able to find any definite traces of his route, or to account for his disappearance, they were instrumental in opening up vast tracts of hitherto unknown territory, and adding largely to the knowledge of the geography of the interior. The following beautiful verses were written by Lynd, a friend of Leichhardt's, and have been set to music:-- "Ye who prepare with pilgrim feet Your long and doubtful path to wend. If whitening on the waste ye meet The relics of my martyred friend.
