The melodious whistle of a bird was frequently heard in the most rocky and wretched spots of the table land. It raised its voice, a slow full whistle, by five or six successive half-notes; which was very pleasing, and frequently the only relief while passing through this most perplexing country. The bullock was killed in the afternoon of the 20th, and on the 21st the meat was cut up and put out to dry; the afternoon was very favourable for this purpose; but, at night rain set in, and with the sultry weather rendered the meat very bad. The mornings were generally sultry and cloudy; during the afternoon the clouds cleared off with the sea-breeze: and towards sunset thunder-storms rose, and the nights were rainy, which prevented me from making observations to ascertain my latitude. The longitude of the descent, was, according to reckoning, 132 degrees 50 minutes. A little before sunset of the 21st four natives came to our camp; they made us presents of red ochre, which they seemed to value highly, of a spear and a spear's head made of baked sandstone (GRES LUSTRE). In return I gave them a few nails; and as I was under the necessity of parting with every thing heavy which was not of immediate use for our support, I also gave them my geological hammer. One of the natives was a tall, but slim man; the others were of smaller size, but all had a mild and pleasing expression of countenance. Large fish betrayed their presence in the deep water by splashing during the night: and Charley asserted that he had seen the tracks of a crocodile. Swarms of whistling ducks occupied the large ponds in the creek: but our shot was all used, and the small iron-pebbles which were used as a substitute, were not heavy enough to kill even a duck. Some balls, however, were still left, but these we kept for occasions of urgent necessity. Nov. 22.--As our meat was not sufficiently dry for packing we remained here the whole of this day; but, at night, the heaviest thunder-storm we perhaps had ever experienced, poured down and again wetted it; we succeeded, however, notwithstanding this interruption, in drying it without much taint; but its soft state enabled the maggots to nestle in it; and the rain to which it had been exposed, rendered it very insipid. Poor Redmond, the last of our bullocks, came frequently to the spot where his late companion had been killed; but finding that he was gone, he returned to his abundant feed, and when I loaded him to continue our journey down the river he was full and sleek. It was interesting to observe how the bullocks on all previous occasions, almost invariably took cognizance of the place where one of their number had been killed. They would visit it either during the night or the next day, walk round the spot, lift their tails, snuff the air with an occasional shake of their horns, and sometimes, set off in a gallop.
