At daylight we steered for a low rocky island, seven or eight miles to the W.N.W., where I took angles from the iron-stone rocks at its south end, and Mr. Bauer examined the vegetable productions. To the S.S.W., about five miles, was a woody point, on the east side of which no land was visible; and the depth of water in coming across from Low Islet having been as much as 10 fathoms, it left a suspicion that a river might fall into the south-west corner of the bay, and induced me to row over to the point. The soundings diminished from 5 to 3 fathoms; in which depth the boat being brought to a grapnel, I found the latitude to be 12° 20′ 27″, from observations to the north and south, and set Low Islet E. 7° S. by a pocket compass.

From thence to the point the water was shallow, and the open space proved to be a shoal bight, with very low land at the back. After I had taken bearings, to ascertain the position of the point and form this side of the bay; we returned northward, passing on the west side of the rocky island; and the ship having arrived at the appointed station, got on board at eight o'clock in the evening.

On laying down the plan of this extensive bay, I was somewhat surprised to see the great similarity of its form to one marked near the same situation in the Dutch chart. It bears no name; but as not a doubt remains of Tasman, or perhaps some earlier navigator, having explored it, I have given it the appellation of the land in which it is situate, and call it. So far as an extent of secure anchoring ground is concerned, it equals any harbour within my knowledge; there being more than a hundred square miles of space fit for the reception of ships, and the bottom seemed to be every where good. Of the inducements to visit Arnhem Bay, not much can be said. Wood is plentiful at all the shores, and the stream which ran down the hills at Mallison's Island would have supplied us conveniently with water, had it been wanted; but in three months afterwards it would probably be dried up. In the upper parts of the bay the shores are low, and over-run with mangroves in many places; but near the entrance they may be approached by a ship, and there
