Oct. 17.--We travelled about eighteen miles N. N. W. over an undulating country, in which Cypress-pine thickets alternated with scrubby stringy-bark forest, and some tea-tree flats. After seven miles, we crossed a large dry creek, which went to the eastward; and, eight miles further, we entered upon a fine box-flat, with hills to the north and north-west. We followed a very promising Pandanus creek, in which the presence of Typha (flag, or bulrush) and a new species of Sesbania indicated the recent presence of water. Mr. Roper having ascended one of the hills, and seen a green valley with a rich vegetation about three miles to the northward, we in consequence left the creek, which turned to the eastward; and, after passing several miles of most wretched scrub, came into an open country, with scattered groves of trees. As the sun was setting, I resolved upon encamping in an open plain, although without water, except what we carried in our large stew-pot. Charley, who had been sent forward, had not yet joined us; I, therefore, ordered two guns to be fired, to let him know where we were; he immediately answered us from a short distance, where he lighted up a cheerful fire. After some time, during which misfortune and carelessness had played us the trick of upsetting our waterpot, Charley arrived with the welcome news that he had found some water-holes in a small creek; we therefore, at moonrise, again saddled our tired animals, and repaired thither. The day had been exceedingly hot; but the passing shadows of cumuli which formed in the afternoon, occasionally afforded us a delightful relief. The sea breeze was strong, particularly towards evening; but the dense scrub and forest kept it from us during the day.
