March 27.--We travelled to lat. 20 degrees 47 minutes 34 seconds. The country along the river is undulating and hilly, and openly timbered. The rock is of sandstone, and the ground is covered with quartz pebbles. In lat. about 20 degrees 49 minutes, the Suttor is joined by a river as large as itself, coming from the S.W. by W., and which changes the course of the Suttor to the N.E. Just before the junction, the large bed of the Suttor contracts into one deep channel, filled in its whole extent by a fine sheet of water, on which Charley shot a pelican. I mention this singular contraction, because a similar peculiarity was observed to occur at almost every junction of considerable channels, as that of the Suttor and Burdekin, and of the Lynd and the Mitchell. I named the river, which here joins the Suttor, after Mr. Cape, the obliging commander of the Shamrock steamer. The bed of the united rivers is very broad, with several channels separated by high sandy bergues. The country back from the river is formed by flats alternating with undulations, and is lightly timbered with silver-leaved Ironbark, rusty gum, Moreton Bay ash, and water box. The trees are generally stunted, and unfit for building; but the drooping tea trees and the flooded-gum will supply sufficient timber for such a purpose. At our camp, at the bed of the river, granite crops out, and the sands sparkle with leaflets of gold-coloured mica. The morning was clear and hot; the afternoon cloudy; a thunder-storm to the north-east. We have observed nothing of the sea-breeze of the Mackenzie and of Peak Range, along the Suttor; but a light breeze generally sets in about nine o'clock P.M. Charley met with a flock of twenty emus, and hunted down one of them.
