A small path along the river margin; marks on trees, where hollow portions of bark had been taken off; some ancient, some recent, huts of withered boughs and dry grass; freshwater muscle shells, beside the ashes of small fires; and, in some places, a small heap of pulled grass (PANICUM LOEVINODE), or of the coral plant; such were the slight but constant indications of the existence of man on the Narran. Such was the only home of our fellow-beings in these parts, and from it they retired on our approach. Ducks, which were rather numerous, and emus (coming to drink), probably constituted their chief food, as nets to ensnare both these kinds of birds, were found about their huts. Youranigh brought me one of their chisels, a small bit of iron fastened to a stick with gum, and tied with a piece of striped shirting. I directed him to place it carefully where he had found it. Thermometer at sunrise, 47 deg.; at noon, 90 deg.; at 4 P. M., 95 deg.; at 9, 69 deg.;--with wet bulb, 60 deg.. The mean height above the sea of the camps of 23d, 24th, and 26th March, was 461 feet. 27TH MARCH.--Pursuing, as well as we could, the course of the Narran, which came more from the northward, we again encamped on its banks after a journey of seven miles, without recognising any indication of the vicinity of the larger stream, which, according to our latitude, we ought by this to have reached. The current here had evidently been more decided, and dry trunks and other FLUVIATILE DEBRIS lay more in masses against whatever had lain in the water's way. Excellent grass clothed the plains over which we had passed during the two last days, and grew abundantly also about the banks of the river; but, in general, a belt of the POLYGONUM JUNCEUM, about 400 or 500 yards wide, grew between the immediate margin and the grassy plains. This shrub was found an infallible guide to the vicinity of the river, when, as sometimes happened, other lines of trees, resembling those on its banks, had led me to a distance from it. The day was cool and rather cloudy, a great novelty to us; for every day had been clear and unclouded, since long before we crossed the Barwan. Abundance of the stones of the quandang fruit (FUSANUS ACUMINATUS) lay at an old fire of the natives, and showed that we were not far from the northern limit of the great clay basin, as the quandang bush grows only upon the lowest slopes of hilly land. Lat. 28 deg. 55' 13" S. Thermometer at sunrise, 70 deg.; at noon, 90 deg.; at 4 P. M., 89; at 9, 70 deg.;--with wet bulb, 61 deg..
