432 SAIL FOR PORT DALRYMPLK. 



south end of the Promontory, and there is no good 

 anchorage between. 



From a small flattened sufjar-loaf, forminfj the 

 summit of Cape Wellington, I got an angle to the 

 Crocodile Rock,* and with others from the south- 

 west end of the Promontory, and from the ship on 

 passing, I determined the position of this danger 

 most satisfactorily. 



As we had not, as I expected, met the Vansittart, 

 I was anxious to learn something of her, and cross- 

 ing over to the south side of the Strait, for the pur- 

 pose, entered Port Dalrymple, where I found that 

 Mr. Forsyth and his party had preceded our arrival 

 by a day or two. The Vansittart's employment had 

 been the examination of the north-east extreme of 

 Tasmania, some portions of which were found to be 

 nine miles out in latitude ; the greater part was 

 fronted with kelp and rocky patches. The work, 

 also, included a portion of Banks' Strait, and the 

 southern part of the western side of Flinders Island, 

 among the islets fronting which were discovered 

 several good anchorages : the best in westerly winds 



* This rock, in lat. 39° 21' 30" S., and long. 4° 41' 45" W. 

 of Sydney, lies in a line midway between the western extre- 

 mities of Curtis and Rodondo Islands, nearly nine miles from 

 each. It is a smooth round-topped granite boulder, just protrud- 

 ing above the surface ; and in fine weather the sea runs over it 

 without breaking. The depth being 43 fathoms close to it, if 

 the waters of the Strait were drawn off the shape of it would be 

 that of a column nearly 260 feet high.
