[Note: This shows how far the custom extends throughout the continent, of considering the rock-crystal as sacred; whether it be that it has been transmitted from tribe to tribe, or that the native was everywhere inclined to pick up a shining stone, and to consider it endowed with peculiar virtues. From the absence of brilliant ores, or precious stones, in the bags and dillis of the natives, I concluded, that neither precious stones nor brilliant metallic substances existed in the country where they lived. Those with whom we came in contact, generally admired our gold and silver chains and watches very much, but had nothing to show in return except broken shells from the sea-coast] Among the new and interesting scrubs and trees which we met with at almost every step, I shall only mention a small Grevillea, from one to two feet in height, with pubescent pinnatifid leaves, and a simple or compound thyrsus of scarlet flowers; Cochlospermum gossypium, the native cotton tree of Port Essington, whose bright showy yellow blossoms and large capsules full of silky cotton, attracted our attention; its leaves are deciduous, and the trees were entirely leafless; a fine species of Calytrix on the rocks, and two of Loranthus on the drooping tea tree, the drooping foliage of which one of them imitated, whilst the other belonged to the group I mentioned as found at the Suttor, with its flowers inserted on a leafy bract. Exocarpus latifolius is so different from E. cupressiformis, in its foliage and aspect, that I did not suspect their near relation, until I found blossom and fruit: the ripe kernel as well as its yellow succulent leaf-stalk have a very agreeable taste; a leguminous shrub, about five or six feet high, with purple blossoms gathered into terminal oblong heads; this would be an ornament to our gardens. Along the river we discovered a large tree, about forty or fifty feet in height, with rather singularly disposed horizontal branches and rich dark green foliage; its leaves were oblong acute, and frequently a foot long; its flowers formed dense heads, which grew into a fleshy body marked with the arcoles of every flower. It is either Sarcocephalus or Zuccarinia, or nearly allied to them. The tree has never been seen on easterly waters, but it was the invariable companion of all the larger freshwater rivers round the gulf. A fine species of Gomphrena was found in the sandy bed of the river. A species of Terminalia, a fine shady tree, with spreading branches and broad elliptical leaves, grew along the sandy creeks; and another smaller one with Samara fruit preferred the rocky slopes. Both of these, and a third species growing on the west side of the gulph, which I shall have to mention hereafter, supplied us with fine eatable gum, and a fourth species, with smooth leaves, had an eatable fruit of a purple colour.
