15TH FEBRUARY.--Mr. Kinghorne obligingly accompanied me this day, and guided us across arms of the marshy ground. I was very glad to have his assistance, for I saw no line of trees as on other rivers, nor other objects by which I could pursue its course or keep near its waters; trees of the aquatic sort and reeds grew together. At one time nothing was visible to the eastward but a vast sea of reeds extending to the horizon. Where the long reeds remained unburnt, they presented a most formidable impediment, especially to men on foot and sheep, and twenty of these got astray as the party passed through. We encamped on a bank of rather firm ground, in lat. 30 deg. 53' 55" S. The grass was very rich on some parts of open plains near the marshes, and the best was the PANICUM LOEVINODE of Dr. Lindley, mentioned in my former journals[*] as having been found pulled, and laid up in heaps for some purpose we could not then discover. Mr. Kinghorne now informed me that it was called by the natives "coolly," and that the gins gather it in great quantities, and pound the seeds between stones with water, forming a kind of paste or bread; thus was clearly explained the object of those heaps of this grass which we had formerly seen on the banks of the Darling. There they had formed the native's harvest field. There also I observed a brome grass, probably not distinct from the BROODS AUSTRALIS of Brown; it called to mind the squarrose brome grass of Europe. Thermometer at sunrise, 59 deg.; at noon, 87 deg.; at 4, 89 deg.; at 9, 73 deg.;--with wet bulb, 66 deg.. [* Vol. i. p. 237.] 16TH FEBRUARY.--Mr. Kinghorne set out with a man of our party to examine Duck Creek, a native boy having told him that water was to be found in it lower down. I sent back early this morning, our native, with the store- keeper, some of the men, and the shepherd, to look for the lost sheep in the reeds, and Yuranigh fortunately found them out, still not very far from the spot where they had been separated from the rest of the flock. Our greatest difficulty in these marshes was the watering of the cattle. We had still the Macquarie at hand--deep, muddy, and stagnant--not above thirty feet wide, the banks so very soft that men could scarcely approach the water without sinking to the knees. We could water the horses with buckets, but not the bullocks. The great labour of filling one of the half-boats, and giving the cattle water by that means, was inevitable, and this operation took up three hours of the morning; a wheel required repair, the box having been broken yesterday. I for these reasons found it advisable to halt this day, which I did very reluctantly. At sunset, Mr. Kinghorne returned, having found no water in the "Marra," (Duck Creek).
