Crossing just below it, we proceeded on a course of 331 degrees over extensive plains, covered with samphire, excepting where the beds of dry salt lagoons occurred.

The ground was spongy and soft, and the cart wheels consequently sank deep into it.

The plain was surrounded on all sides by sand hills, and that towards which we were advancing appeared to run athwart our course instead of nearly parallel to it as heretofore.

On gaining the summit, we found that other ridges extended from it in parallel lines, the ridge on which we stood forming the head of the respective valleys.

A line of acacia, a species we had never found near water, was growing down the centre of each, and the fall of the country seemed again to be to the N.N.W.
Pushing down one of the valleys, the descent of which was very gradual, and keeping on such clear ground as there was, the ridges rose higher and higher on either side of us as we advanced, all grass and other vegetation disappeared, and at length both valley and sand ridge became thickly coated with spinifex.
At noon I halted, in the hope of obtaining a meridian altitude, but was disappointed, as also at night, the sky continuing obscured.
