pieces of a foot long, or more, like iron bars, and had a shining, ore-like appearance; and the strata were then further from the horizontal line than I observed them to be elsewhere.

A thick wood covered almost all that part of the island visible from the ship; but the trees in a vegetating state were not equal in size to the generality of those lying on the ground, nor to the dead trees standing upright. Those on the ground were so abundant, that in ascending the higher land, a considerable part of the walk was made upon them. They lay in all directions, and were nearly of the same size and in the same progress towards decay; from whence it would seem that they had not fallen from age, nor yet been thrown down in a gale of wind. Some general conflagration, and there were marks apparently of fire on many of them, is perhaps the sole cause which can be reasonably assigned; but whence came the woods on fire? That there were no inhabitants upon the island, and that the natives of the continent did not visit it, was demonstrated, if not by the want of all signs of such visit, yet by the tameness of the kanguroo, an animal which, on the continent, resembles the wild deer in timidity. Perhaps lightning might have been the cause, or possibly the friction of two dead trees in a strong wind; but it would be somewhat extraordinary that the same thing should have happened at Thistle's Island, Boston Island, and at this place, and apparently about the same time. Can this part of Terra Australis have been visited before, unknown to the world? The French navigator, La Pérouse, was ordered to explore it, but there seems little probability that he ever passed Torres' Strait.

Some judgment may be formed of the epoch when these conflagrations happened, from the magnitude of the growing trees; for they must have sprung up since that period. They were a species of eucalyptus, and being less than the fallen trees, had most probably not arrived at maturity; but the wood is hard and solid, and it may thence be supposed to grow slowly. With these considerations, I should be inclined to fix the period at not less than ten, nor more
