Near the landing-place, at the foot of Mount Flinders, were a few isolated gum-trees, and small clusters of the casuarina, which were the only trees on the northern island. Some drift timber was on the south-east and north-west sides. On the latter was a tree of considerable size, doubtless brought from the shore of the Gulf by the North-West monsoon. Its whole surface was covered with a long brown kind of grass, interwoven with creepers. There were great quantities of a cinnamon-coloured bittern seen, as well as quails, doves, and large plovers, but not any of the bustards mentioned by Flinders. We saw no traces of land animals of any kind; neither did we of the natives. A flock of screaming white cockatoos had taken up their abode on the south island, where also some bulbs of the Angustifolia were found. A few small fish, besides sharks, were caught alongside the ship. I was surprised to find the tides an hour later than at Van Diemen's Inlet; their velocity, likewise, was increased to two knots; the flood-stream came from the north-east at the anchorage. FOWLER ISLAND. July 7. At daylight, we left for Sweers Island; but owing to light winds, chiefly easterly, did not reach Investigator Road, between Sweers and Bentinck Islands, before the afternoon of the 8th. The soundings on the way were generally 9 fathoms, fine sandy mud. A small islet, lying off the South-East side of Bentinck Island, and forming the immediate eastern side of the Road, I named after the first lieutenant of the Investigator, now Captain Fowler. Under Mount Inspection, a hill 105 feet high, and the most remarkable feature hereabouts, on the South-East extreme of Sweers Island, a party of twelve natives was observed as we passed. They gazed silently at us, making no demonstration of joy, fear, anger, or surprise. It is possible they may have been stupefied by the appearance of that wonderful creation of man's ingenuity--a ship; in their eyes it must have seemed a being endowed with life walking the waters, for purposes to them incomprehensible, on a mission to the discovery of which they could not even apply the limited faculties they possessed. Fortunately or unfortunately for them--according as we determine on the value of civilization to the aboriginal races of the South--they did not possess the fatal, or salutary, curiosity that prompts most men to attempt fathoming the depth of whatever is mysterious. Restrained by their fears, or by their ignorant, or philosophical indifference, they did not again show themselves: and though when we landed we once or twice thought we heard sounds of life in our vicinity, the natives of the island never again came under our observation. It is remarkable that the same circumstance happened to Flinders. He also perceived human beings at a distance; but when he endeavoured to communicate with them, they retired, as he mentions, to some of the caverns that exist on the island, and were seen no more.
