From Mr.
McMinn I obtained the course and distance of the pillar from our camp, and travelling on the course given, we crossed the Finke three times, as it wound about so snake-like across the country.

On the 22nd we encamped upon it, having the pillar in full view.
(ILLUSTRATION: THE Moloch horridus.) The appearance of this feature I should imagine to be unique.

For a detailed account of it my reader must consult Stuart's report.
Approaching the pillar from the south, the traveller must pass over a series of red sandhills, covered with some scrubs, and clothed near the ground with that abominable vegetable production, the so-called spinifex or porcupine grass--botanically, the Triodia, or Festuca irritans.

The timber on the sandhills near the pillar is nearly all mulga, a very hard acacia, though a few tall and well-grown casuarinas--of a kind that is new to me, namely the C.
Decaisneana--are occasionally met.

(These trees have almost a palm-like appearance, and look like huge mops; but they grow in the driest regions.) On our route Mr.Carmichael brought to me a most peculiar little lizard, a true native of the soil; its colour was a yellowish-green; it was armed, or ornamented, at points and joints, with spines, in a row along its back, sides, and legs; these were curved, and almost sharp; on the back of its neck was a thick knotty lump, with a spine at each side, by which I lifted it; its tail was armed with spines to the point, and was of proportional length to its body.
