The whole of the territory east of the overland line was now rapidly becoming settled, and the explorations made by Mr. Macphee east of Daly Waters may be said to have concluded the list of expeditions between the overland line and the Queensland border. In 1883 the South Australian Government determined to complete the exploration of Arnheim's Land, and Mr. David Lindsay was dispatched on the mission. He left Palmerston on the 4th June, and proceeded, by way of the Katherine, to the country north of the Roper River. From there they proceeded to Blue Mud Bay, and, on the way, had a narrow escape from being massacred by the natives, who speared four horses, and made an attempt to surprise the camp. Lindsay got entangled in the broken tableland that caused such trouble to Leichhardt, and, with one misfortune and another, lost a great number of his horses-in fact, at one time, he anticipated having to abandon them all, and make his way into the telegraph station on foot. On the whole, the country passed over was favourable for settlement; in fact, the flats on some portions of his course were first-class sugar country. Another journey was undertaken about this time by Messrs. O'Donnell and Carr Boyd into Western Australia, starting from the same place as Lindsay, namely, the Katherine telegraph station. The expedition succeeded in finding a large amount of pastoral country, but no new geographical discoveries of any importance were made. Meantime, the discovery of gold in the Kimberley district of Western Australia led to that province being searched by small prospecting parties, and every creek and watercourse becoming known. This has left but little of the coastal lands still unexplored in Australia, and there is scant chance of anything noticeable being found in the interior beyond what we can fairly conjecture. The utmost an explorer can now hope to find there is some permanent lagoon or spring, affording a stand-by for the pastoralist. No such streams as the Murray or Darling will ever again gladden the eyes of the traveller in the interior, The greater part of the territory still left to explore is situated in one colony--that of Western Australia, and, although the interior has been successively crossed by so many different men, there yet remains a large area which may be called unknown. Of what the end will be it is hard to say. Shall we find it bear out the gloomy predictions of Warburton and Giles? or the more hopeful one of Forest? One thing we do know--that, year after year, use is being found for the most repellent country. When we look back at the verdict pronounced against the interior of Australia by the early explorers, and how it has been falsified by time there is ground for hoping that even the most despised portions of our continent will yet be found available for something.
