Sept. 4.--We travelled about eleven miles west by north. The first three miles and a half led us through scrub; we forded a salt-water creek about thirty yards broad, and then, for the next four miles, proceeded through a scrubby country, and came to a second salt-water creek as broad as the first, but containing only pools of water. The scrub now opened, and the last four miles lay through a fine box-flat, bounded by long hollows surrounded with drooping tea-trees and the white water-gum, the bright foliage of which formed a most agreeable contrast with the dull green of the scrubs and the box-trees. After crossing a small sandy creek, along which grew a few Sarcocephalus, we came to a large creek lined with drooping tea-trees and Sarcocephalus, and encamped on a fine pool of water, within its deep bed. I named this creek after W.C. Wentworth, Esq. M.C. who had kindly contributed to the outfit of my expedition. At early dawn, a flight of wild geese filed in long line over our camp, the flapping of their wings was heavy, but short, and the note they emitted resembled that of the common goose, but was some-what shriller. In the box-flat we started a flock of emus, and Spring caught a fine male bird. It would have been highly amusing for a looker on to observe how remarkably eager we were to pluck the feathers from its rump, and cut the skin, to see how thick the fat was, and whether it was a rich yellow, or only flesh-coloured. We had, indeed, a most extraordinary desire for anything fat; and we soon found where to look for it. In the emu it accumulates all over the skin, but particularly on the rump, and between the shoulders, and round the sternal plate. To obtain the oil, we skinned those parts, and suspended them before a slow fire, and caught the oil in our frying pan; this was of a light yellowish colour, tasteless, and almost free from scent. Several times, when suffering from excessive fatigue, I rubbed it into the skin all over the body, and its slightly exciting properties proved very beneficial. It has always been considered by the white inhabitants of the bush, a good anti-rheumatic. The sea breeze from the northward still continued during the day; the nights were clear and dewy, but ceased to be so cold. I found a piece of granite and a fragment of fortification agate in the sandy bed of the creek.
