thought himself lost, got disheartened, grumbled and became exceedingly annoying to me; but I could not help feeling for him, as he complained of severe pain in his legs. We now entered extensive Ironbark flats, which probably belong to the valley of the Mackenzie. Giving our position every consideration, I determined upon returning to the mountains at which we had turned, and took a north-west course. The country was again most wretched, and at night we almost dropped from our saddles with fatigue. Another pigeon was divided between us, but our tea was gone. Oppressed by hunger, I swallowed the bones and the feet of the pigeon, to allay the cravings of my stomach. A sleeping lizard with a blunt tail and knobby scales, fell into our hands, and was of course roasted and greedily eaten. Brown now complained of increased pain in his feet, and lost all courage. "We are lost, we are lost," was all he could say. All my words and assurances, all my telling him that we might be starved for a day or two, but that we should most certainly find our party again, could not do more than appease his anxiety for a few moments. The next morning, the 21st, we proceeded, but kept a little more to the westward, and crossed a fine openly timbered country; but all the creeks went either to the east or to the north. At last, after a ride of about four miles, Brown recognized the place where we had breakfasted on the 19th, when all his gloom and anxiety disappeared at once. I then returned on my south-east course, and arrived at the camp about one o'clock in the afternoon; my long absence having caused the greatest anxiety amongst my companions. I shall have to mention several other instances of the wonderful quickness and accuracy with which Brown as well as Charley were able to recognize localities which they had previously seen. The impressions on their retina seem to be naturally more intense than on that of the European; and their recollections are remarkably exact, even to the most minute details. Trees peculiarly formed or grouped, broken branches, slight clevations of the ground--in fact, a hundred things, which we should remark only when paying great attention to a place--seem to form a kind of Daguerreotype impression on their minds, every part of which is readily recollected. I rejoined my party at the creek which comes from Mount Stewart. The natives had approached Mr. Gilbert when out shooting, with a singular, but apparently friendly, noise: "Ach! Ach! Ach!" They had heard the cooce of my blackfellow Charley, and thought Mr. Gilbert wanted them; but, as he was alone, he thought it prudent to retire to the camp.
