The men were obliged to put handkerchiefs over their faces, and stockings upon their hands; but they bit through every thing. It was to no purpose that I myself shifted from place to place; they still followed, or were equally numerous everywhere. To add to our discomfort, the animals were driven almost to madness, and galloped to and fro in so furious a manner that I was apprehensive some of them would have been lost. I never experienced such a day of torment; and only when the sun set, did these little creatures cease from their attacks. SUDDENLY RELIEVED. It will be supposed that we did not stay to subject ourselves to another trial; indeed it was with some degree of horror that the men saw the first light of morning streak the horizon. They got up immediately, and we moved down the creek, on a northerly course, without breakfasting as usual. We found that dense brushes of casuarina lined the creek on both sides, beyond which, to our left, there was open rising ground, on which eucalypti, cypresses, and the acacia longifolia, prevailed; whilst to the east, plains seemed to predominate. Although we had left the immediate spot at which the kangaroo flies (cabarus) seemed to be collected, I did not expect that we should have got rid of them so completely as we did. None of them were seen during the day; a proof that they were entirely local. They were about half the size of a common house fly, had flat brown bodies, and their bite, although sharp and piercing, left no irritation after it. About noon we stopped at the creek side to take some refreshment. The country bore an improved appearance around us, and the cattle found abundance of pasture. It was evident that the creek had been numerously frequented by the natives, although no recent traces of them could be found. It had a bed of coarse red granite, of the fragments of which the natives had constructed a weir for the purpose of taking fish. The appearance of this rock in so isolated a situation, is worthy of the consideration of geologists. DESOLATION OF THE COUNTRY.
