June 5.--We travelled, in a direct line, about nine miles west by north, down the river, although the distance along its banks was much greater; for it made a large bend at first to the northward, and afterwards, being turned by a fine conspicuous short range, to the westward. I named the Range after W. Kirchner, Esq., another of the supporters of my expedition. The river was here, in some places, fully half a mile broad, and formed channels covered with low shrubs, among which a myrtle was frequent. Between the ranges, the river became narrower: and, before it reached Kirchner's Range, a large creek joined it from the eastward; and another from the southward, after it had passed the range. The flats increased on both side of the river, and were openly timbered with box and narrow-leaved Ironbark. The rock near our yesterday's camp was talc-schist. Farther down sienite was observed, which contained so much hornblende as to change occasionally into hornblende rock, with scattered crystals of quartz. Granite and pegmatite were round some lagoons near the creek from the southward. The clustered fig tree of the Burdekin, became again more frequent; but Sarcocephalus was the characteristic tree of the river. The Acacia of Expedition Range and of the upper Lynd, grew to a comparatively large size in the open forest. We observed a cotton tree (Cochlospermum), covered with large yellow blossoms, though entirely leafless; and we could not help thinking how great an ornament this plant would be to the gardens of the colony. As the water-holes became larger, water-fowl became more plentiful; and Brown succeeded in shooting several wood-ducks and a Malacorhyncus membranaceus. The bean of the Mackenzie was very abundant in the sandy bed of the river; we roasted and ate some of its fruit; it was, however, too heavy, and produced indigestion: Mr. Phillips pounded them, and they made an excellent substitute for coffee, which I preferred to our tea, which, at that time, was not very remarkable for its strength. June 6.--We travelled about nine miles west by north to latitude 17 degrees 30 minutes 47 seconds. The first part of the stage was over an undulating country timbered with box and Ironbark; but the latter part was hilly and mountainous: the mountains were so rocky, where they entered the bed of the river, that we were obliged to leave its banks, and travel over a very difficult country. On the small flats, the apple-gum grew with a few scattered Moreton Bay ash trees; on the bergues of the river we found the white cedar (Melia azedarach), Clerodendron; an asclepiadaceous shrub with large triangular seed-vessels; and, on the hills, the blood-wood and stringy-bark. The rock, as far as I examined it, was of porphyry of great hardness, and composing hills of an almost conical form.
