and even in that distance there is much more shoal than deep water.

The rocks lying at the entrance of the basin are covered at the top of the flood, but at other times are much frequented by shags. After observing the latitude and taking bearings there, I went down to Green Island; and the tide being then out, perceived the shoals in Sea Reach to be so numerous and extensive, that it was surprising how the sloop could have reached thus far without striking upon some of them. In the channel to the east of Green Island I found from 7 to 25 fathoms, and both the sides of it steep to; a rock lies in the middle of the passage, but at twenty yards from it there was 3 fathoms all round. Green Island is covered with long, coarse grass and bushes, with a few small trees intermixed. The large, noisy gulls frequent it for the purpose of breeding, as do the swans, several of whose deserted nests were found with the broken egg-shells in them. These were corroborating proofs, that the natives of this part of Van Diemen's Land have not the means of transporting themselves across the water; for Green Island is scarcely two cables length from the shore.

In returning to the sloop, I took off Mr. Bass and his party, together with a kanguroo weighing between eighty and ninety pounds, which he had shot out of a considerable flock. Our fresh provisions were still further increased by an addition of six swans, caught this evening with the boat.

Nov. 5 was employed in the survey of the Western Arm, and searching, but in vain, for the means of conveniently replenishing our water casks. Next morning we steered across the basin, and sought to anchor under an island which, from its situation at the entrance of the eastern arm, was called Middle Island; but there not being a sufficient depth of water behind it, the course was continued up the eastern arm, in 10 or more fathoms water, for two or three miles; when we anchored upon a five-fathom bank, near a small cove on the northern shore. On landing, a little stream was
