It was rather remarkable that the Moreton Bay ash, which is so abundant along the Burdekin, was altogether wanting at the Clarke.
Several lagoons were observed at the foot of the ridges; and near them we saw two flocks of the harlequin pigeon (Peristera histrionica).
Talc-schiste cropped out in one of the deep creeks.

Whilst travelling on the Burdekin, with the exception of some ducks and a few kangaroos, we had seen but very little game; but yesterday, when riding to the Clarke, two flocks of kangaroos passed me: a proof that the country is not so destitute of game as I had thought.

The waters are inhabited by four varieties of fish; one was probably a Gristes, about eight inches long, and from one and a half to two inches broad, of a lanceolate shape, with bright yellow spots all over the body; a second smaller than Gristes, with dark stripes; a third about a foot long, and three inches broad, belonging to the Percidae; and a fourth, a small fish, which seemed to be allied to the Cyprinidae.

Larger fish exist, probably, in the deep rocky basins of water which we occasionally passed; but we never succeeded in catching any; nor did we hear any of the splashing, which was so incessant during the night at the Mackenzie.

The shell and bones of the turtle indicated its presence in the shady ponds fringed by drooping tea trees.
