Notice of Captain Clavering. •S 



registering log was used as a check upon the estimated reckon- 

 ing, and proved the value and efficacy of the attention paid to 

 the latter, by its being a rare circumstance to find a difference 

 between them amounting to a mile in twenty-four hours. 



Upon the returti of the Pheasant to Great Britain, the Board- 

 of Longitude determined that Captain Sabine's Observations on 

 the Pendulum should be continued to the most northerly lati- 

 tude to which it was possible to reach. For this purpose the 

 Griper, which was one of the vessels that had been engaged in 

 Captain Parry's first expedition in 1819-20, was selected, and 

 Captain Clavering appointed to the command. 



It will be seen that he availed himself of every opportunity 

 that presented itself for prosecuting discoveries, and enlarging 

 the boundaries of geographical science. A considerable part of 

 the east coast of Greenland explored by him, was seen in the 

 preceding year by Captain Scoresby ; but, from his distance 

 from die land, that able navigator had not the same means of 

 laying it down correctly to the north of Cape Parry which he 

 had to the south of that headland, when he was close in with 

 the land. In the chart the discoveries of both navigators are 

 laid down, and form an actual survey of the coast from Lat. 69° 

 to Lat. 76° :, for, although Captain Clavering did not reach far- 

 ther north than Shannon Island, yet the positions of the bluff head 

 lands to the north of Roseneath Inlet, and the islands named, 

 from their appearance, Haystack and Ailsa, were determined by 

 astronomical bearings from ,tvvo hills, one on the outermost, and 

 the other on the innermost, of the Pendulum Islands ; and the 

 distance between the two stations was ascertained by a trigono- 

 metrical operation. 



Although the principal object of the voyage was to convey 

 Captain Sabine to the different stations. Captain Clavering did 

 not consider it necessary to give any of the results of his obser- 

 vations in his account, as they were already published, and well 

 known to the scientific world.
