EXCURSION TO THE NORTH-WEST. The weather was excessively hot, and as my men were but slowly recovering, I was anxious while those who were in health continued active, to give the others a few days of rest. I proposed, therefore, to cross the river, and to make an excursion into the interior, during the probable time of Mr. Hume's absence; since if, as I imagined, the Macquarie had taken a permanent northerly course, I should not have an opportunity of examining the distant western country. Mr. Hume's experience rendered it unnecessary for me to give him other than general directions. A PLAIN ON FIRE. On the last day of the year we left the camp, each accompanied by two men. I had the evening previously ordered the horses I intended taking with me across the channel, and at an early hour of the morning I followed them. Getting on a plain, immediately after I had disengaged myself from the reeds on the opposite side of the river, which was full of holes and exceedingly treacherous for the animals, I pushed on for a part of the wood Mr. Hume had endeavoured to gain from the boat, with the intention of keeping near the marsh. On entering it, I found myself in a thick brush of eucalypti, casuarinae and minor trees; the soil under them being mixed with sand. I kept a N.N.W. course through it, and at the distance of three miles from its commencement, ascended a tree, to ascertain if I was near the marshes; when I found that I was fast receding from them. I concluded, therefore, that my conjecture as to their direction was right, and altered my course to N.W., a direction in which I had observed a dense smoke arising, which I supposed had been made by some natives near water. At the termination of the brush I crossed a barren sandy plain, and from it saw the smoke ascending at a few miles' distance from me. Passing through a wood, at the extremity of the plain, I found myself at the outskirts of an open space of great extent, almost wholly enveloped in flames. The fire was running with incredible rapidity through the rhagodia shrubs with which it was covered. Passing quickly over it, I continued my journey to the N.W. over barren plains of red sandy loam of even surface, and bushes of cypresses skirted by acacia pendula. It was not until after sunset that we struck upon a creek, in which the water was excellent; and we halted on its banks for the night, calculating our distance at twenty-nine miles from the camp. The creek was of considerable size, leading northerly. Several huts were observed by us, and from the heaps of muscle-shells that were scattered about, there could be no doubt of its being much frequented by the natives. The grass being fairly burnt up, our animals found but little to eat, but they had a tolerable journey and did not attempt to wander in search of better food. I shot a snipe near the creek, much resembling the painted snipe of India; but I had not the means with me of preserving it. A TRIBE OF NATIVES.
