Oct. 19.--During the night, north-easterly breeze; at the break of day, a perfect calm; after sunset easterly winds again. Thermometer at sunrise 51 degrees (60 degrees in the water); a cloudless sky. Mr. Hodgson and Charley, whom I had sent to seek John and Caleb, returned to the camp with a kangaroo. I sent them immediately off again, with Mr. Roper, to find the two unfortunate people, whose absence gave me the greatest anxiety. Mr. Roper and Mr. Gilbert had brought one pigeon and one duck, as a day's sport; which, with the kangaroo, gave us a good and desirable supper of animal food. During the evening and the night, a short bellowing noise was heard, made probably by kangaroos, of which Mr. Gilbert stated he had seen specimens standing nine feet high. Brown brought a carpet snake, and a brown snake with yellow belly. The flies become very numerous, but the mosquitoes are very rare. On a botanical excursion I found a new Loranthus, with flat linear leaves, on Casuarina, a new species of Scaevola, Buttneria, and three species of Solanum. Mr. Hodgson brought a shrubby Goodenia; another species with linear leaves, and with very small yellow blossoms, growing on moist places in the forest; two shrubby Compositae; three different species of Dodonaea, entering into fruit; and a Stenochilus, R. Br. with red blossoms, the most common little shrub of the forest. Mr. Gilbert brought me a piece of coal from the crossing place of the creek of the 10th October. It belongs probably to the same layer which is found at Flagstone Creek, on Mr. Leslie's station, on Darling Downs. We find coal at the eastern side of the Coast Range, from Illawarra up to Wide Bay, with sandstone; and it seems that it likewise extends to the westward of the Coast Range, being found, to my knowledge, at Liverpool Plains, at Darling Downs, and at Charley's Creek, of the 10th Oct. It is here, as well as at the east side, connected with sandstone. Flint pebbles, of a red colour, were very abundant at Charley's Creek, and in the scrub, which I called the Flourspill, as it had made such a heavy inroad into our flour-bags. The flat on which we encamp, is composed of a mild clay, which rapidly absorbs the rain and changes into mud; a layer of stiff clay is about one foot below the surface. The grasses are at present in full ear, and often four feet high; but the tufts are distant, very different from the dense sward at the other side of the Range. As we left the Myal country of the Condamine, we left also its herbage, abounding in composite, leguminous, and chenopodiaceous plants, with a great variety of grasses.
