shelter. Also the coast between False Cape Horn and Weddell Cape, 
which is to the westward of this harbour, being the parts of this coast 
that have not been sufficiently examined by Captain King. 
He will be accompanied by a passed midshipman on this duty : the 
launch is to be fitted with her deck, sails, &c, with a crew of ten 
men, and provisions, among which are included preserved meats, 
&c, for twenty days, and a small whale-boat (the Fox), or another, if 
deemed more suitable, a tent, and every other convenience that he 
may deem requisite to make the service efficient and comfortable to 
the party. He will proceed on this duty as soon after my departure 
as his preparations and the weather will permit ; and great hopes are 
entertained that he will be enabled to complete these arduous and 
important duties before my return. This service is considered a 
hazardous one, and he will use every endeavour to avoid risking 
himself, men, and boats, as in the event of any loss of the latter, 
much detention would result to the after operations of the Expedition. 
It is hoped that Lieutenant Aid en will be enabled, prior to this 
duty being undertaken, to finish the chart of the Rio Negro. 
Acting Master North will assist Lieutenant Carr in the care and 
attention to the chronometers, their rate, observations, &c. 
It is expected that all passed midshipmen, and midshipmen, will 
exert themselves in carrying out the various and important duties 
confided to them at this anchorage.
