The Acacia of Expedition Range was plentiful in the large flat and at the wells of the natives, and formed a fine tree: its seeds, however, were shed, and had been roasted by the late bush fire. Mr. Phillips (who was always desirous of discovering substitutes for coffee, and to whom we owed the use of the river-bean of the Mackenzie) collected these seeds, and pounded and boiled them, and gave me the fluid to taste, which I found so peculiarly bitter that I cautioned him against drinking it; his natural desire, however, for warm beverage, which had been increased by a whole day’s travelling, induced him to swallow about a pint of it, which made him very sick, and produced violent vomiting and purging during the whole afternoon and night. The little I had tasted acted on me as a lenient purgative, but Mr. Calvert, who had taken rather more than I did, felt very sick. The gum of this Acacia was slightly acid, and very harmless.
Oct. 30.—We travelled about four miles to the N.W. and N.N.W. along the summit of rocky ranges, when a large valley bounded by high ranges to the north and north-west, burst upon us. We descended into it by a steep and rocky basaltic slope, and followed a creek which held a very tortuous course to the south-west; we had travelled along it about seven miles, when Charley was attracted by a green belt of trees, and by the late burnings of the natives, and discovered a running rivulet, coming from the N.N.W. It was fringed with Pandanus, Acacia (Inga monilifornis) and with an arborescent Vitex, with ternate leaves. The flats were well grassed, and lightly timbered with box and white-gum. On the flat summit of the sandstone ranges, we observed the Melaleuca gum, the rusty gum, the mountain Acacia, and Persoonia falcata, (R. Br.) The basaltic rock was apparently confined to the upper part of the valley, where it had broken through the sandstone, which composed all the ranges round our camp, the latitude of which I observed to be 14 degrees 23 minutes 55 seconds. At our last camp, I observed a Platycercus, of the size of the Moreton Bay Rosella, with blackfront, yellow shoulders, and sea-green body; the female had not the showy colours of the male, and the young ones were more speckled on the back. I believe it to be the Platycercus Brownii, Gould. A black and white Ptilotis, the only stuffed specimen of which was taken by a kite almost out of Mr. Gilbert’s hand, was very frequent at the wells of the natives.
