We did not see anything more of the blacks during the rest of the day, but the repeated indications of hostility we perceived as we approached the Darling, made me apprehensive as to the reception we should meet from its numerous population; and I was sorry to observe that the men anticipated danger in passing that promising junction. Having left the sea breezes behind us, the weather had become oppressive; and as the current was stronger, and rapids more numerous, our labour was proportionably increased. We perspired to an astonishing degree, and gave up our oars after our turn at them, with shirts and clothes as wet as if we had been in the water. Indeed Mulholland and Hopkinson, who worked hard, poured a considerable quantity of perspiration from their shoes after their task. The evil of this was that we were always chilled after rowing, and, of course, suffered more than we should otherwise have done. RE-PASS THE LINDESAY. On the 25th we passed the last of the cliffs composing the great fossil bed through which the Murray flows, and entered that low country already described as being immediately above it. On a more attentive examination of the distant interior, my opinion as to its flooded origin was confirmed, more especially in reference to the country to the S.E. On the 30th we passed the mouth of the Lindesay, and from the summit of the sand hills to the north of the Murray overlooked the flat country, through which I conclude it must run, from the line of fires we observed amid the trees, and most probably upon its banks. We did not fall in with the natives in such numbers as when we passed down to the coast: still they were in sufficient bodies to be troublesome. It would, however, appear that the tribes do not generally frequent the river. They must have a better country back from it, and most probably linger amongst the lagoons and creeks where food is more abundant. The fact is evident from the want of huts upon the banks of the Murray, and the narrowness of the paths along its margin. RE-PASSED THE RUFUS.
