De Witt's Isles, (so named, probably, by Tasman) twelve in number, are of various sizes. The two largest are from three to four miles in circuit. Their sides are steep, but their height is inferior to that of the main. The largest is the lowest. The smaller isles are little more than large lumps of rock, of which that named by Captain Cook the mew stone is the southernmost. Their aspect, like that of the main, bespeaks extreme sterility; but, superior to the greater part of it, they produce a continued covering of brush; and upon the sloping sides of some of their gullies are a few stinted, half dead gum trees. They could not account for the vestiges of fires that appeared upon the two inner large islands; the innermost in particular, which lay at some distance from the nearest point of the main, was burnt in patches upon different parts of it. It must have been effected either by lightning, or by the hand of man; but it was so much unlike the usual effects of the former, that, with all its difficulties, they chose to attribute it to the latter cause. A great smoke that arose at the back of one of the bights showed the main to be inhabited; but they could not suppose the people of this place to be furnished with canoes, when those of Adventure Bay, in their neighbourhood, were unprovided with them. Nothing, therefore, was left to their choice, but to allow that they might transport themselves over, either upon logs of wood, or by swimming across: and, as the most probable reward of such an exertion would be the capture of birds, whilst breeding, or the seizure of their eggs, the utility of spreading fires in facilitating such operations is obvious. The south cape may be easily distinguished from any other projection in its vicinity. Besides being the southernmost, it is a promontory making like a foreland, and sloping very gradually as it runs towards the sea, where it ends in a perpendicular cliff. About sunset the fresh NW wind died away suddenly; and a strong squall from the westward, with thunder, lightning, and heavy rain, soon carried them round the south cape, and, by dark, brought them off what was formerly called Storm Bay, where they hauled to the wind with the sloop's head up the bay, intending, in the morning, to proceed by this Storm Bay passage into the Derwent river. The night was squally, and by day light the next morning (the 14th), it was found that the vessel had drifted across the mouth of Storm Bay, or more properly Storm Bay Passage. Tasman's Head, its eastern point, bore NE distant three miles. Being too far to leeward to fetch up the passage, and the gale continuing, they bore away round Tasman's Head, and hauled up along shore for Adventure Bay.
