were then on a high box-tree ridge, in view of a thick scrub; we hobbled our horses, and covered ourselves with our blankets; but the storm was so violent, that we were thoroughly drenched.  As no water-holes were near us, we caught the water that ran from our blankets; and, as we were unable to rekindle our fire, which had been extinguished by the rain, we stretched our blankets over some sticks to form a tent, and notwithstanding our wet and hungry condition, our heads sank wearily on the saddles—­our usual bush pillow—­and we slept soundly till morning dawned.  We now succeeded in making a fire, so that we had a pot of tea and a pigeon between us.  After this scanty breakfast, we continued our course to the north-east.  Brown 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.
