2D AUGUST.--We had approached this fine river over a park-like plain, but lower down we found the banks lined with scrub. I pursued a N.W. course in passing through it, and emerged on plains and open forests alternating with scrubs. The scrubs were remarkable, as always involving dry hollows where water had lodged. The clay was then hard; but, in all these hollows, the deep impressions of naked feet of men, women, and children, remained since the bottom had consisted of mud. These numerous receptacles for water, when it is sent, attest the wisdom with which even the clods of the valley have been disposed for the benefit of the animal world. The day's journey was long, and chiefly through that sort of scrub. I was disappointed in my hope of falling in with the river, by travelling N.W. Yuranigh descried from a tree, the continuation, far to the westward, of the low range that had been already seen from a former camp. Its direction had then appeared to be nearly N. and S. The turn the river had taken westward was, therefore, favourable to my hopes, that it would continue in that direction. Its general course was found to be nearly northward. On the other hand, the high ranges in the E. seemed to terminate abruptly towards the N., so that a very low country appeared to be to the northward of our position then, stretching from 40 deg. N. of W. to 40 deg. E. of N., a full quarter circle which the course of the river almost bisected. After travelling twelve miles without seeing any thing of the river, I reluctantly turned N.E., and then E., and in the last-mentioned direction, I hit the river where it contained a fine reach of water. In the dry part of the bed, grew various curious plants in flower, all quite new to me; a species closely allied to the ACACIA DELIBERATA (Cunn.), and a very fine silky leaved TRICHODESMA.[*] A new VELLEYA was also found near this camp.[**] In the scrubs back from the river, the STENOCHILUS CURVIPES was loaded with its long tubular flowers. A small species of Acacia was perhaps a variety of A. LEUCADENDRON Cunn.; and we found also a curious scrubby species of JACKSONIA.[***] Latitude, 22 deg. 30' 10" S.
