The space thus left to be explored, from the Champagny Isles to Cape Leveque, corresponds to more than one hundred miles in a direct line; within which extent nothing but islands and detached portions of land have yet been observed.

One large inlet especially, on the south-east of Cape Leveque, appears to afford considerable promise of a river; and the rise of the tide within the Buccaneer's Archipelago, where there is another unexplored opening, is no less than thirty-seven feet.
The outline of the coast about Cape Leveque itself is low, waving, and rounded; and the hue for which the cliffs are remarkable in so many parts of the coast to the north, is also observable here, the colour of the rocks at Point Coulomb being of a deep red: but on the south of the high ground near that Point, the rugged stony cliffs are succeeded by a long tract, which to the French voyagers (for it was not examined by Captain King) appeared to consist of low and sandy land, fronted by extensive shoals.

It has hitherto been seen, however, only at a distance; so that a space of more than three hundred miles, from Point Gantheaume nearly to Cape Lambert, still remains to be accurately surveyed.
Depuch Island, east of Dampier's Archipelago, about latitude 20 degrees 30 minutes, is described by the French naturalists as consisting in a great measure of columnar rocks, which they supposed to be VOLCANIC; and they found reason to believe that the adjoining continent was of the same materials.* It is not improbable, however, that this term was applied to columns belonging to the trap formation, since no burning mountain has been any where observed on the coast of New Holland: nor do the drawings of Depuch Island, made on board Captain King's vessel, give reason to suppose that it is at present eruptive.

Captain King's specimens from Malus Island, in Dampier's Archipelago (sixty miles farther west) consist of greenstone and amygdaloid.
(*Footnote.

Peron volume 1 page 130.) The coast is again broken and rugged about Dampier's Archipelago, latitude 20 degrees 30 minutes; and on the south of Cape Preston, in latitude 21 degrees, is an opening of about fifteen miles in width, between rocky hills, which has not been explored.
