I rode about five miles beyond the river to the north-west, and met, first with a very broad lagoon full of water, nearly on a level with the plains, and apparently permanent; secondly, I found beyond this, a river or chain of ponds somewhat like the Narran. This I ascertained was called the Cawan by the natives, and that it meandered very much. The country was rather fine. These waters were bordered by well-grown trees, and the plains were covered with good grass. Lat. of our camp, on the Balonne, 28 deg. 25' 38" S. Thermometer at sunrise, 44 deg.; at noon, 75 deg.; at 4 P.M., 79 deg.; at 9, 60;--with wet bulb, 54 deg.. Height of the bed of the Balonne above the level of the sea, 494 feet; an average of three observations. 2D APRIL.--All the drays and the party crossed the river this morning in good order, and without any accident or much delay, by the little bridge we had made in its bed. While they were crossing, the place seemed to me so favorable for a ford that it might still be possible to find some of the marked trees said to be at "Congo." I again questioned the natives on this point, and one youth undertook to point out some marks made by white men. Mr. Kennedy ran with him on foot up the left bank of the river, and was shown two trees marked, the one with "J. Towns," the other with "Bagot, 1845." Being thus convinced that this ford was really at or near the place called "Congo," where Commissioner Mitchell had crossed, and found the Culgoa, at a distance of only seven miles north-west, I determined to go forward, in the same direction, to that river, taking my track of yesterday, which enabled me to avoid the broad lagoon.
