The weather about this time was extremely oppressive and close. Thunder clouds darkened the sky, but no rain fell. The thermometer was seldom below 104 at noon, and its range was very trifling. The wind shifted several times during the twenty-four hours; but these changes had no effect on the thermometer. It was evident, however, as the sun set on the evening of the 26th, that the clouds from which thunder had for the last four or five days disturbed the silence of nature around us, would not long support their own weight. A little before midnight, it commenced raining, and both wind and rain continued to increase in violence until about seven in the morning of the 27th; when the weather moderated. Two or three blacks had accompanied us from the last tribe, and had lain down near the fire. As the storm increased, however, they got up, and swimming across the river, left us to ourselves. This was a very unusual thing, nor can I satisfy myself as to their object, unless it was to get into shelter, for these people though they wander naked over the country, and are daily in the water, feel the cold and rain very acutely. Observing the clouds collecting for so many days, I indulged hopes that we were near high lands, perhaps mountains; but from the loftiest spots we could see nothing but a level and dark horizon. Anxious to gain as correct a knowledge of the country as possible we had, in the course of the day, ascended a sandy ridge that was about a mile from the river. The view from the summit of this ridge promised to be more extensive than any we had of late been enabled to obtain; and as far as actual observation went, we were not disappointed, although in every other particular, the landscape was one of the most unpromising description. To the S. and S.E., the country might be said to stretch away in one unbroken plain, for it was so generally covered with wood that every inequality was hidden from our observation. To the S.W. the river line was marked out by a succession of red cliffs, similar to those we had already passed. To the north, the interior was evidently depressed; it was overgrown with a low scrub, and seemed to be barren in the extreme. The elevations upon which we stood were similar to the sand-hills near the coast, and had not a blade of grass upon them. Yet, notwithstanding the sterility of the soil, the large white amarillis which grew in such profusion on the alluvial plains of the Macquarie, was also abundant here. But it had lost its dazzling whiteness, and had assumed a sickly yellow colour and its very appearance indicated that it was not in a congenial soil. LINDESAY RIVER.
