extended west; and it therefore appeared to me probable that the river would be found at its base. In the evening we heard, at a short distance from our camp, the songs of females or children; as if the overflowing of their animal spirits. I had seen their smoke in a part of the range I passed this day, to which I feared they had fled on our approach, hearing our guns, and in terror of strangers. I was, therefore, glad to find that they had no longer any dread of us, and had returned to THEIR home, the river bank. These people had no clothing,--the mercury stood at 19 deg. and 20 deg. F.; the means of subsistence open to them, had been scarcely enough to have kept white men alive, even with the aid of their guns. Yet, under such circumstances, and with such strange visitors so close to them, these human beings were so contented and happy, that the overflowings of their hearts were poured forth in song! Such is human nature in a wild state. Their happiness was not such as we could envy; on the contrary, I was so solicitous that we should not disturb it, that, much as I wished to learn the original name of this interior river, and something about its course, I forbade any of the party from taking any notice of these, its original inhabitants. Our last intercourse with the natives, had also taught me to bear ever in mind aesop's fable of the camel. Thermometer, at sunrise, 12 deg.; at noon, 52 deg.; at 4 P. M., 56 deg.; at 9, 32 deg.. 24TH MAY.--I proceeded, with two men bearing axes, to a hill about two miles S. W. of our camp, one of the extremities of the range already mentioned, (which I call River Head Range). We passed, at no great distance from our camp, those natives whose song we had heard last evening, but without taking any notice of them, except by slightly waving my hand. One tall female stooped amongst the long grass, and several others, male and female, endeavoured to hide themselves in a similar manner, as they beheld, probably for the first time, a white man on horseback, followed by others bearing a saw and axes. On the summit, grew the Malga tree; which is an acacia of such very hard wood, that I was obliged to be content to cut off the top branches only of a tree on the summit I had endeavoured to cut down, and to erect a sort of platform on the remainder, whence I took my angles. Up the river, there appeared some open plains, and a level horizon, in the direction of its apparent course. Thermometer, at sunrise, 11 deg.; at noon, 65 deg.; at 4 P. M., 67 deg.; and at 9, 30 deg..
