Charley told me last night, on his return from a walk, that he had found sandstone.

To-day we travelled over porphyries like those of the last stage: but, about four miles from the last camp, steep sandstone rocks with excavations appeared on our left, at some distance from the river, from which they were separated by porphyry; but, farther on, they approached the river on both sides, and formed steep slopes, which compelled us to travel along the bed of the river itself.

Two large creeks joined the river from the southward, one of which was running, and also made the river run until the stream lost itself in the sandy bed.

At the end of the stage, however, the stream re-appeared, and we were fairly on the fourth flowing river of the expedition: for the Condamine, although not constantly, was raised by rains, and showed the origin of its supply, by the muddy nature of its waters; the Dawson commenced running where we left it; and the Burdekin, with several of its tributaries, was running as far as we followed it.

The waters of the Dawson, the Burdekin, and the Lynd, were very clear, and received their constant supply from springs.
We passed a camp of natives, who vere very much alarmed at the report of a gun, which Mr.Gilbert happened to fire when very near them; this he did in his anxiety to procure a pair of Geophaps plumifera, for his collection.
