June 27.--In crossing the southern extremity of these large plains, we came suddenly upon a small party of natives engaged in digging yams of which the plains were full; they were so intent upon their occupation that we were close to them before they were aware of our presence; when they saw us they appeared to be surprised and alarmed, and endeavoured to steal off as rapidly as they could without fairly taking to their heels, for they were evidently either unwilling or afraid to run; finding that we did not molest them they halted, and informed us by signs that we should soon come to water, in the direction we were going. This I knew to be true, and about three o'clock we were in front of a water-course, I had on a former journey named the "Rocky river," from the ragged character of its bed where we struck it. We had been travelling for some distance upon a high level open country, and now came to a sudden gorge of several hundred feet below us, through which the Rocky river wound its course. It was a most singular and wild looking place, and was not inaptly named by the men, the "Devil's Glen;" looking down from the table land we were upon, the valley beneath appeared occupied by a hundred little hills of steep ascent and rounded summits, whilst through their pretty glens, flowed the winding stream, shaded by many a tree and shrub--the whole forming a most interesting and picturesque scene. The bed of the watercourse was over an earthy slate, and the water had a sweetish taste. Like most of the Australian rivers, it consisted only of ponds connected by a running stream, and even that ceased to flow a little beyond where we struck it, being lost in the deep sandy channel which it then assumed, and which exhibited in many places traces of very high floods. Below our camp the banks were 50 to 60 feet high, and the width from 60 to 100 yards, its course lay through plains to the south-west, over which patches of scrub were scattered at intervals, and the land in its vicinity was of an inferior description, with much prickly grass growing upon it. Upwards, the Rocky river, after emerging from the gorges in which we found it, descended through very extensive plains from the north-north-east; there was plenty of water in its bed, and abundance of grass over the plains, so that in its upper parts it offers fine and extensive runs for either cattle or sheep, and will, I have no doubt, ere many years be past, be fully occupied for pastoral purposes. From our present encampment a very high and pointed hill was visible far to the N.N. W. this from the lofty way in which it towered above the surrounding hills, I named Mount Remarkable. Our latitude at noon was 33 degrees 25 minutes 26 seconds S.
