which was excellent; but, as they seemed to have trusted to our generosity, I left every thing in its place, and departed. Brown thought that one of them looked like a half-caste, and, as they had called us, as far as we understood, "whitefellows," I felt confirmed in my supposition, either that a white man was with them, or had lived among them very recently. I returned to the creek, in order to find another water-hole with water; but did not succeed, and had to encamp without it. During the night we heard the noise of a frog, "brrr, brrr;" probably a new species, for we had never heard that croak before. It seemed, however, to frighten Brown, who, like all blackfellows, is very timid after night-fall. Yesterday we met with a new leguminous shrub. It belongs to the section Cassia, and has a long pinnate leaf, the leaflets an inch long, and half an inch broad. Its pods were about a foot long, half an inch broad; and every seed was surrounded by a fleshy spongy tissue, which, when dry, gave to the pod a slightly articulate appearance. The seeds, when young, had an agreeable taste, and the tissue, when dry, was pleasantly acidulous, and was eaten by some of my companions without any ill effect, whilst others, with myself, were severely purged. To day I found the same plant in form of a tree, about thirty feet high, with a short stem, and long spreading shady branches.
