Tuesday 22.
children were perceived on the north-east beach; and on walking that way we saw two bark huts, and an elderly man was sitting under a tree, near them. He smiled on finding himself discovered, and went behind a bush, when a confused noise was heard of women and children making off into the wood; the man also retreated up the hill, and our friendly signs were ineffectual to stop him. In one of the huts was a net bag, containing some pieces of gum, bone, and a broken spike nail; and against a neighbouring bush were standing three spears, one of which had a number of barbs, and had been wrought with some ingenuity. This I took away; but the rest of the arms, with the utensils and furniture of the huts, consisting of the aforesaid net bag and a shell to drink out of, were left as we found them, with the addition of a hatchet and pocket handkerchief.
Cotton's, Pobassoo's, and Astell's Islands, to which our examinations were limited, are moderately high, woody land; they slope, down nearly to the water on their west sides, but on the east, and more especially the south-east, they present steep cliffs; and the same conformation seemed to prevail in the other islands. The stone of the upper parts is grit or sand-stone, of a close texture; but the lower part of the cliffs is argillaceous and stratified, splitting in layers of different thicknesses, from that of a shilling to two or three feet; and the strata dip to the westward, about 15°. On breaking some pieces out of the cliffs, I found them curiously marked with the representation of flowers and trees, owing, as I am told, to manganese or iron ore inserting itself partially into the fissures. The layers are of a reddish colour, resembling flat tiles, and might, I conceive, be used as such, almost without any preparation; there are enough of them to cover a whole town, and the sand stone at the top of the cliffs is equally well calculated for building the walls of the houses.
The upper surfaces of these islands are barren; but in the vallies, down which ran streams of water at this time, there is a tolerable soil. One of these vallies, at the south end of Cotton's
