trees, (rhizophori,) a plant universally found in warm southern latitudes, close to the margins of salt-water creeks and sheltered portions of the sea-shore. The roots of the mangrove send up numerous perpendicular shoots, to which shell-fish are often found adhering after the ebb of the tide—a circumstance which has given rise to the seemingly marvellous story of oysters growing upon trees. Its ashes afford potass in great abundance, and in New South Wales they are used extensively in the manu facture of soap. The waters of the creek are extremely well stocked with fish, especially mullet, bream, and snappers, among which a few sharks manage to get a livelihood; and the exam ples of these members of the squalus tribe are imitated to excellent advantage by a considerable number of indus trious bipeds, the demand for fresh fish being generally very great in Adelaide. The finny multitudes afford, also, a maintenance to numerous birds of the duck, teal, and cormorant species, which usually poise themselves indo lently among the mangrove branches, from which they can easily descry their prey. The receding tide usually leaves behind it large quantities of muscles, cockles, and other molluscae. The largest and most remarkable of these is the pinna marina, or silk muscle, of which I found a few specimens. The cuttle-fish, (loligo vulgaris,') whose internal shell is very useful as a dentifrice, is found here in abundance; and I observed also the species of antennarius, or toad-fish, whose poisonous qualities on one occasion proved fatal to a whole family in Van Dieman’s Land. Its ugly and loathsome aspect will not easily be forgotten by those who have once seen it. From e 3
