The forenoon was cloudless and hot; cirrhous clouds formed in the afternoon; with a breeze from the E.S.E. Our lat. was 21 degrees 25 minutes. Mr. Gilbert and Charley, when on a reconnoitring ride, met another party of natives; among them two gins were so horror-struck at the unwonted sight, that they immediately fled into the scrub; the men commenced talking to them, but occasionally interrupted their speeches by spitting and uttering a noise like pooh! pooh! apparently expressive of their disgust. March 23.--The party moved on about ten miles to the north-east, and encamped at the junction of a large creek which comes from the S.S.E. Its character is similar to that of the Suttor; and I should not be surprised if it should prove to be the northern anabranch of that creek, and which we crossed on the 17th of March, the day before we arrived at the lake. The country opens into lightly-timbered ridges, which are composed of a hard rock, the sharp pieces of which covered the ground, and made our animals foot-sore. It seems to me to be a clayey sandstone (Psammite) penetrated by silica. A coarse-grained sandstone and quartzite cropped out in that part of the river situated between the two camps. The melon-holes of the box-flats were frequently over-grown with the polygonaceous plant, mentioned at a former occasion; and the small scrub plains were covered with a grey chenopodiaceous plant from three to four feet high. The stiff-leaved Cymbidium was still very common, and two or three plants of it were frequently observed on the same tree; its stem is eatable, but glutinous and insipid.
