On the 24th, at three o'clock in the morning, we discovered the coast of Van Diemen's Land, bearing N. 1/2 W. At four o'clock the S.W. cape bore N.N.W. 1/2 W., and the Mewstone N.E. by E. three leagues distant. There are several islands and high rocks lying scattered along this part of the coast, the southernmost of which is the Mewstone. It is a round elevated rock, five or six leagues distant from the S.W. cape, in the direction of S. 55° E.
At noon, our latitude was 43° 47' S. longitude 147° E., and the situation of the lands round us as follows: An elevated round-topped hill bore N. 17° W.; the S.W. cape N. 74° W.; the Mewstone W. 1/2 N.; Swilly Isle, or Rock, S. 49° E.; and the S.E. of S. cape N. 40° E. distant near three leagues. The land between the S.W. and S. capes is broken and hilly, the coast winding, with points shooting out from it; but we were too far off to be able to judge whether the bays formed by these points were sheltered from the sea-winds. The bay which appeared to be the largest and deepest, lies to the westward of the peaked hill above mentioned. The variation of the compass here was 5° 15' E.
At six o'clock in the afternoon we sounded, and found sixty fathoms water, over a bottom of broken coral and shells. The S. cape then bore N. 75° W. two or three leagues distant; Tasman's Head N.E.; and Swilly Rock S. by W 1/2 W. About a league to the eastward of Swilly is another elevated rock, that is not taken notice of by Captain Furneaux. I called it the Eddystone, from its very great resemblance to that light-house. Nature seems to have left these two rocks here for the same purpose that the Eddystone light-house was built by man, viz. to give navigators notice of the dangers around them; for they are the conspicuous summits of a ledge of rocks under water, on which the sea, in many places, breaks very high. Their surface is white with the dung of sea-fowls; so that they may be seen at some distance even in the night. On the N.E. side of Storm Bay, which lies between the S. cape and Tasman's Head, there are some coves or creeks, that seemed to be sheltered from the sea-winds; and I am of opinion, that, were this coast examined, there would be found some good harbours.
