The thunder roared and the cloud broke darkly over us, but its liquid contents seemed to evaporate in the middle air. At half-past seven a strong hot wind set in from the north-east and continued during the night. Thermometer 90 degrees. I was suddenly awoke from feverish sleep by a violent shaking of my tent, and I distinctly heard the flapping of very large wings, as if some bird, perhaps an owl, had perched upon it. January 5. The sun's rays were scorching before his red orb had cleared the horizon, but ere he appeared the party was in motion. No dew had fallen, yet even the distressed bullocks and horses seemed to participate in the hope which led us forward. With one accord men and quadrupeds hastened from the inhospitable valley, common sufferers from the want of an element so essential to the living world. Continuing on the same bearing of 24 degrees east of north we reached the highest part of some clear ground, at about two miles from where we had encamped, and from this spot I obtained an extensive view over the country before us. The ground sloped for several miles towards a line of trees beyond which a steep ridge extended parallel to that line, and upwards to the mountains, evidently enclosing a channel of drainage, so that I ventured at once, on seeing this, to assure the men that I saw where we should meet with water. The way to it was all downhill, open and smooth; while the Nundewar range, now to the southward, presented, on this northern side, a beautiful variety of summits. WATER FOUND NEXT DAY. DISCOVER A SMALL RIVER. I galloped impatiently towards the line of wood, and found there a meandering channel full of water, with steep banks of soft earth, apparently a small river, and I hastened back with the welcome intelligence to the men. The extreme heat and the fatigue of travelling could not have been borne much longer. One man (Woods) had been left behind at his own request, being unable even to ride, from violent pains in his stomach; another was also so ill that he could not walk; the bullocks still drew, but with their tongues protruding most piteously. I sent a man on horseback back with a kettleful of water to Woods. The cattle being unyoked rushed to the stream, and in half an hour we were all comfortably encamped, with good grass beside us for the cattle. The bottom of this small river-channel was in no part gravelly, but consisted of soft earth, in which however the cattle did not sink very deep. Fragments of flint, basalt, and quartz, apparently not worn by attrition, abound in the adjacent soil. The general direction of the watercourse appeared to be about 36 degrees north of west. DUCKS. At a pond above our camp the carpenter shot two ducks of a kind not previously seen by us, having a purple speck on the head, behind the ear.
