The general course of the river during the day was very little to the south of east, its banks still maintaining the same rocky and precipitous character, marks of inundation being frequently observed at the height of thirty feet above the present stream, which now was only running gently in a channel not more than thirty yards wide, but when in flood occupying the whole of the valley, which averages a quarter of a mile in width. The larger pools are lined with flags and reeds, and contain numbers of small fish resembling trout, similar to those found in the Lyons and Gascoyne Rivers. A very handsome tree, resembling an ash, grew on the margin, bearing a beautiful white flower, four to five inches across, having on the inside a delicate tinge of yellow, and yielding a sweet scent like violets. Several natives were met in the course of the day, but would not come near us; in one instance, however, we came upon one so suddenly that he had only time to jump into a pool to escape being surrounded by the party. After calling for some time most lustily for his friends, he gradually crept away amongst the canes and disappeared. Only one tributary of any size was observed to join the river in the course of the day's march, and that came in from the southward. At 5.20 p.m. halted on the banks of a deep pool, surrounded by fine cajeput-trees and flooded-gum, grass being plentiful for our horses. Camp 8. ENCOUNTER DIFFICULT COUNTRY. 1st June. There was a decided improvement in the appearance of the valley as we continued to ascend the river, the deep pools were more continuous, and grass more abundant; the high lands on either bank still, however, retained their rugged outlines, and were clothed with little else but triodia. Travelling along the bed of the river was nevertheless difficult and dangerous for the horses, on account of the immense quantity of rounded boulders of water-worn rocks that occupied a large portion of the channel, and frequently jammed the horses into narrow passes, where they could not be extricated without meeting with very severe falls, which very soon crippled more than one of them; their shoes also began to be wrenched off by being caught in the deep clefts of the rocks, very soon expending all the extra sets brought with us. Just before coming to our night's halt a large stream-bed, forty yards wide, was observed to come in from the southward. Camp 9. Latitude 21 degrees 28 minutes 18 seconds; longitude 116 degrees 31 minutes by account. 2nd June (Sunday). Having abundance of feed and water, we gladly availed ourselves of it to make it a day of rest; it also afforded me an opportunity to ascertain the rate of the chronometer, which, as I had reason to expect, had gone very irregularly since landing. 3rd June.
