Camp 24. Course 90 degrees, heavy dew, beautiful morning. The water although running strong here is of a milky appearance. Started at 8.10 a.m. over granite ridge and crossed swamp and water-creek to north. At two and a quarter miles boulders of lava on the eastern side; at two and three-quarter miles crossed large creek with plenty of water, which I have called Frank's Creek after F. Marchant, Esquire, of Arkaba north of Adelaide. It comes from southward. At four and a half miles crossed small running rivulet from south; at five miles crossed a larger one from same direction; at six and three-quarter miles crossed a running creek in a swamp from south also; at seven and three-quarter miles crossed a splendid creek with oaks, etc., quantity of swampy ground on either side flowing same as last, which I have called the George after George Marchant, Esquire, of Wilpena north of Adelaide. At ten and a quarter miles crossed rivulet running to south; at ten and three-quarter miles examined boggy swamp with plenty of water, drainage to south. At eleven miles on top of small rocky range. Most extensive view ahead of level-looking country. At twelve and a half miles boggy swamp, went round the south end of it, its drainage is northward; at fifteen miles crossed a good-sized creek with sandy bed, some oaks, the water merely trickling through the sand but sufficient for all our wants; good timber. Camped here. Two of the horses nearly knocked up. Creek flows east on passing this. Sunday, June 29.
