Resuming our journey at 8.10 a.m., steered north-east down the valley of the creek, which I named Elsey Creek, after the surgeon of the expedition. Its course was generally to the north-east, but spreading into lagoons and swampy flats, became very tortuous and irregular. It then changed to a very winding reach of water fifty to sixty yards wide, with low banks covered with reeds and tall melaleuca-trees, beyond which was a belt of pandanus growing on the drier ground. Many small springs rose in the limestone rock and ran into the creek, on the banks of which large quantities of mussel-shells showed the frequent camps of the blacks. The banks of the creek and springs were so soft and boggy that our horses could not approach the water, and we followed its banks in search of a spot where they could drink in safety, till 4.0, without success, and having camped, had to water the horses with our leather buckets. Latitude by a2 Centauri and a Coronae Borealis 15 degrees 5 minutes 35 seconds. ROPER RIVER. 15th July. Leaving our camp at 7.10 a.m., steered north-east till 9.0, over level country, which appeared to be very swampy in the rainy season; altered the course to 10 degrees magnetic, and crossed a small dry watercourse which proved to be a continuation of Elsey Creek. At 11.0 turned 60 degrees magnetic, and shortly came on the bank of a fine river with banks thirty to forty feet high, and fine reaches of water fifty to eighty yards wide; at 11.45 camped at the junction of Elsey Creek and the river, which appears to be the Roper of Dr. Leichhardt. The fan-palm was frequently seen on the banks of Elsey Creek, where it obtained a height of fifty to eighty feet, and had a thicker stem and produced a more palatable vegetable than the species growing on the banks of the Victoria River. KILL AN EMU. 16th July.
