Dr. Leichhardt does not expect to be able to accomplish this overland journey to Swan River, in less than two years and a half. According to a letter written by him on the eve of his departure (Dec. 6, 1846); his party consisted of six whites, and two blacks; he had purchased thirteen mules, twelve horses, and two hundred and seventy goats; and bad received forty oxen, three mules, and two horses, as presents. He then purposed to travel over his old route, as far as Peak Range, and then to shape his course westwards; but thought it not impossible, as his course depends on water, that be should be obliged to reach the Gulf of Carpentaria, and then to follow up some river to its source.--Ed.] The End
