The weather very fine, but hot; the wind westerly; thermometer at sunset 74 degrees (84 degrees in the water.) Oct. 23.--At the commencement of last night, westerly winds, the sky clear; at the setting of the moon (about 3 o'clock a.m.), the wind changed to the north-east; scuddy clouds passing rapidly from that quarter; at sunrise it clears a little, but the whole morning cloudy, and fine travelling weather. We travelled in a north-westerly direction, through a Casuarina thicket, but soon entered again into fine open Ironbark forest, with occasionally closer underwood; leaving a Bricklow scrub to our right, we came to a dry creek with a deep channel; which I called "Acacia Creek," from the abundance of several species of Acacia. Not a mile farther we came on a second creek, with running water, which, from the number of Dogwood shrubs (Jacksonia), in the full glory of their golden blossoms. I called "Dogwood Creek." The creek came from north and north-east and flowed to the south-west, to join the Condamine. The rock of Dogwood Creek is a fine grained porous Psammite (clayey sandstone), with veins and nodules of iron, like that of Hodgson's creek. A new gum-tree, with a rusty-coloured scaly bark, the texture of which, as well as the seed-vessel and the leaf, resembled bloodwood, but specifically different; the apple-tree (Angophora lanceolata); the flooded-gum; a Hakea with red blossoms; Zierea; Dodonaea; a crassulaceous plant with handsome pink flowers; a new myrtaceous tree of irregular stunted growth, about 30 feet high, with linear leaves, similar to those of the rosemary; a stiff grass, peculiar to sandstone regions; and a fine Brunonia, with its chaste blue blossoms, adorn the flats of the creek as well as the forest land. The country is at present well provided with water and grass, though the scattered tufts of Anthistiria, and the first appearance of the small grass-tree (Xanthorrhaea), render its constancy very doubtful. The winding narrow-leaved Kennedyas, Gnaphaliums in abundance; Aotus in low bushes. No game, except a kangaroo rat, pigeons, ducks, and mutton-birds. Mr. Phillips brought a crawfish from the creek: it had just thrown off its old shell. Fresh-water muscles plentiful, though not of the size of those of the Condamine. A small rat was caught this morning amongst our flour bags; it had no white tip at the tail, nor is the tail so bushy as that of the rabbit-rat: probably it was a young animal.
