June 21.—­We did not get away until late, but the dew had been so heavy during the night that even then the shrubs and bushes wet us completely through, and made our journey cold and miserable.  After travelling a short distance we lost all symptoms of grass, and the country was again sandy and barren, and covered with shrubs and heathy plants.  In this region we passed two native women and a boy, within gun-shot of us; but as they were so intent upon their occupation of digging roots, and did not notice us, I was unwilling to alarm them, and we passed silently by.  At six miles we came to a fine deep hole of excellent water about thirty yards in circumference.  It was situated in a narrow, short, but steep and rocky gorge, and is, I think, permanent.  Four miles beyond this we crossed a chain of salt ponds, trending seawards, towards an apparent gap in the coast-line; and six miles further another.  Upon the latter we halted for the night, as there was good grass for the horses, and brackish water was procurable a little way up the stream, where it divided into branches.  The constant travelling in the wet for the last few days began now to affect our limbs considerably, and upon halting at nights we found our feet always much swollen, and our legs generally stiff and cramped.

June 22.—­A very heavy dew fell in the night, and we were again condemned to wade for three hours up to our middle among the wet brush; after which the day became fine, and we got our clothes dried.  Travelling for two and a half miles, we crossed another small brackish chain of ponds, and then ascending rather higher ground, obtained a view of a large lake under the sand-hills, into which the channel we encamped upon last night emptied itself.  The lake appeared as if it were deep, and its dark blue colour led me to imagine there might be a junction with the sea towards the south-west, where the low appearance of the coast ridge indicated a gap or opening of some kind.  At four miles from our last night’s encampment we were stopped by a large salt-water river, fully a hundred yards wide, and increasing to three or four times that size as it trended to its junction with the large lake, and which was visible from the hills above the river.  This river was deep where we first struck upon it, but appeared to be much more so towards the lake, where the water was of a dark blue colour, as was that also of the lake itself.  This confirmed me in my opinion that there must be a junction with the sea; but unfortunately I was obliged to trace its course upwards, for the purpose of crossing, and the circumstances under which I was travelling precluded me from delaying, or going so far back out of my way to examine its mouth.  I dared not leave Wylie in charge of the camp for the time necessary for me to have gone alone; and to take the horses such a distance, and through a rough or heavy country, on the uncertainty of procuring for them either grass or water, would have been a risk which, in their condition, I did not think myself justified in incurring.
