Made an early start, and as the valley of the river was not quite so rugged as that we had passed over during the last two or three days, by noon we had accomplished about eight miles, the course of the river still being very little from the southward of east; we had not, therefore, made much progress towards the Lyons River (our more immediate destination), and to quit the valley was out of the question, as there is no feed or water out of it within a reasonable distance. Both the valley and surrounding country are destitute of trees, and bold hills of metamorphic sandstone frequently jut out into the valley, and terminate in perpendicular cliffs 200 or 300 feet high. Towards the evening the river had been coming from the northward of east. Camp 10. Latitude 21 degrees 27 minutes 48 seconds. 4th June. During the forenoon the river became much hemmed in by steep rocky hills, the bed being a succession of rapids, over a bare, rocky channel; but after the noon halt the stream came more from the south-east, with wide grassy flats on either side, in many parts very boggy, and producing Melaleuca leucodendron, with tall, straight stems, and a variety of eucalyptus, resembling Eucalyptus piperita. White sandstone and shales began to make their appearance on the banks, and the water in the river had a saline taste. Several of the horses began to show signs of being much distressed, by falling and sticking fast in the mud, from which they had not strength to extricate themselves, even after being relieved of their loads. Ducks were plentiful, and tolerably tame. Camp 11. Latitude 21 degrees 33 minutes 55 seconds; longitude 117 degrees 2 minutes by account. SANDSTONE CLIFFS. 5th June.
