our camps." In this district a botanical novelty, in the form of a bread-fruit tree, was found, and used to some advantage. As the Lynd did not lead in the most suitable direction, it was left, and a straight line taken to the Gulf. This was the occasion of the discovery of another river, which was called the Mitchell, in honour of the distinguished explorer; but it, too, was given up for a shorter course. In this quarter a deplorable accident occurred. The camp was attacked during night by the blacks, when Gilbert, the naturalist to the expedition, was killed. From this point the journey was continued round the head of the Gulf. Numerous rivers were crossed, some of which had been long before discovered by exploring navigators, and others were now for the first time brought to light. Among the latter were the Gilbert and the Roper, both receiving names in honour of members of the expedition. The Roper River had many tributaries, one of which was called Flying-Fox Creek, from the myriads of these creatures which had chosen it for their haunt. Leichhardt says:--"I went with Charley and Brown to the spot where we had seen the greatest number of flying-foxes, and whilst I was examining the neighbouring tree, my companions shot 67, of which 55 were brought to our camp, which served for dinner, supper, and luncheon." By the 24th of November the expedition had crossed the watershed between the streams flowing into the Gulf and those heading for the Indian Ocean. After much toilsome travel, the South Alligator River was reached, about 60 miles from its mouth and 140 from Port Essington. In this locality the waterfowl are described as being seen, not in crowds, but in "clouds." "Here," says Leichhardt, "we should have been tolerably comfortable but for a large green-eyed fly, which was extremely troublesome to us, and which scarcely allowed our poor horses to feed." In order to avoid some bad, rocky ground, the party turned to the south and struck the East Alligator River. The last stage of the journey was travelled under the direction of a native guide, and the goal of the expedition reached in safety. After a month's rest in this settlement, Leichhardt found a schooner bound for Port Jackson, and embraced this opportunity of returning to Sydney by sea. His unexpected appearance there seemed like an apparition from the other world. For a long time he had been given up for lost, and a search expedition had already come back unsuccessful. The citizens of Sydney at once instituted a public subscription for Leichhardt and his associates, who had thus travelled over 3,000 miles in fifteen months. The amount reached the figure of £1,500, which was supplemented by a Government grant of £1,000. The Royal Geographical Societies, also, hastened to show their appreciation of the explorer's labours by presenting him with their gold medals. These rewards had been as honestly earned as they were handsomely made. The route he had laid open was, indeed, useless
