The breadth was uniform, and the vast body of water was a most cheering sight. The banks were 120 yards apart, the course in general very straight, contributing much to the perspective of the scenery upon it. At one turn, denuded rocks appeared in its bed, consisting of ironstone in a whitish cement or matrix, which might have been decomposed felspar. I at length arrived at a natural bridge of the same sort of rock, affording easy and permanent access to the opposite bank, and at once selected the spot for a depot camp, which we established on a fine position commanding long vistas both up and down the river. It was, in fact, a tete-de-pont overlooking the rocky passage which connected the grass on both sides. This was No. VIII., and in latitude 28 deg. 1' 37''. Thermometer, at sunrise, 68 deg.; at noon, 104 deg.; at 4 P. M., 101 deg.; at 9, 74 deg.;--with wet bulb, 64 deg.. 13TH APRIL.--Here I could leave the jaded cattle to refresh, while, with a small party on horse-back, I could ascertain the farther course of the river, and explore the country to the north-west where centred all my hopes of discovery. I set on foot various preparations, such as the stuffing of saddles, shoeing of horses, drying of mutton, and, first of all in importance, though last likely to be accomplished, the making a pair of new wheels for a cart to carry water. Thermometer, at sunrise, 47 deg.; at noon, 100 deg.; at 4 P. M., 101 deg.; at 9, 67 deg.;--with wet bulb, 62 deg.. 15TH APRIL.--This day I sent Mr. Kennedy to examine the country in the direction of 3311/2 deg., my intended route, and he returned about 10 P. M., having seen what he considered indications of the river on his right when about twelve miles from the camp, and plains to the left. Upon the whole, I resolved, from what he said of the scrubs he had met with, to travel north-west, that direction being perpendicular to the general course of this river, and therefore the most likely to lead the soonest to higher ground. Thermometer, at sunrise, 68 deg.; at noon, 104 deg.; at 4 P. M., 103 deg.; at 9, 72 deg.;--with wet bulb, 67 deg..
