In the course of the evening we travelled six and a half miles further in a south-south-east direction, over barren, sandy, scrubby plains, which extended on all sides as far as the eye could see, and even the interior range appeared to be perfectly bare. Towards nightfall we were all quite worn out from the difficulty we had experienced in walking through the prickly scrub, yet I could see no place that afforded sufficient wood to enable us to make a fire and, as most of us had no covering with us, and the nights were intensely cold, we had every prospect of passing a most wretched one; but at length I spied two clumps of Banksia trees, the nearest of which we just reached as it became quite dark. The other clump was about a quarter of a mile to the eastward of us, at which I soon distinguished native fires; as the men were however much exhausted I thought it better not to mention this circumstance to them, and Kaiber and myself, who always slept at a little fire alone, kept a good look out during the night. This evening we found the Bohn or Boh-rne, a native esculent root, and it is the most northern point at which I have met with it.* (*Footnote. A small red root somewhat resembling in flavour a mild onion.) April 12. Before dawn this morning our native neighbours, who doubtless were not pleased at our sleeping so near them, began to cooee to each other, which is their usual signal for collecting their forces; and, as our safety depended upon none of the party being incapacitated by a wound or other cause from proceeding with the utmost rapidity, I at once roused the men and we resumed our way. CONTINUE OUR ROUTE. In the course of the day we made a march of twenty-five miles in a south-south-east direction, the whole of this distance being across elevated undulating sandy plains, covered with a thick prickly scrub, about two and a half feet high; these plains were however occasionally studded with a few Banksia trees, but anything more dark, cheerless, and barren than their general appearance can scarcely be conceived. About half an hour before sunset we came to the bed of a dry watercourse, the direction of which was from south-east to north, so that it was probably a tributary of the Arrowsmith. We were fortunate enough to find a small pool of water in it, yet the large flights of birds of every description that came here for the purpose of drinking showed the rarity of water in these parts. We made several attempts to get a shot at them but they were so wild, and we were so worn out and weak, that all our exertions were unsuccessful. In the course of the evening one of the men made up my last pound of flour into a damper for me, and I supped on a spoonful of arrowroot. SERIOUS ROBBBRY BY A RAT. April 13.
