May the object of our journey be successful, thought I then; and we may also hope that these beauties of nature may no longer "waste their sweetness in the desert air;" and that more of her graces may thus be brought within the reach of art. Noble reaches next extended in fine perspective before us; each for several miles, presenting open grassy margins along which we could travel on firm ground unimpeded by scrub. At length I perceived before me a junction of rivers, and could see along each of them nearly a mile. I had no alternative but to follow up that nearest to me, and found upon its bank many recent encampments of natives; at one of which the fires were still burning. The country was grassy, and so open, as almost to deserve the colonial name of "plain." This channel took me a long way northward, and to the N. N. E.; but finally turned west, and at last south. Its bed was full of sand; and at length we found it quite dry, so that, when I would have encamped, I could find no water. Yet it bore all the character of a large river; marks of high floods, Mimosae, sand, and river driftwood, like the other. It might, and probably did, finally come out of the main channel; but this seemed too remote a contingency for our wants then, and I crossed it, to look for the other. In riding eastward, I found a wide plain bounded by trees that looked like those along the river. No time could be spared for further reconnoissance: I took the party across, and made for the nearest part. My course was first N. E., then East, finally South, in following the various slopes; and it was only after travelling fifteen miles beyond the point where I met with this river, that I reached the bank of the other, at a spot distant only FOUR miles from where I had quitted it. This was only accomplished at forty minutes after 4 P. M., when we had travelled twenty-six miles. As our circuitous route was likely, if followed by Mr. Kennedy with the heavy drays, to cause delay and inconvenience, I resolved to halt next day, and write to him on the subject, explaining how he could most readily fall into my track by crossing the other channel, quitting first the other track, at a spot to be marked by Graham, who took the letter. Nevertheless, it had been imperative on me to follow it up as I had done; because, whether as a separate tributary or an ana-branch only, the right bank was likely to suit us best, provided only that water could have been found in its bed. Near the new river, the INDIGOFERA HIRSUTA of Linnaeus, with its spikes of reflexed hairy pods, was common; and also the MOSCHOSMA POLYSTACHYUM. Lat. 27 deg. 47' 57'' S.
