The difficulties that present themselves to Navigators in 

 passing round Cape Horn, as well from adverse winds as the 

 severe gales and heavy sea to which they are exposed, are so -great, 

 that the Strait of Magalhaens has naturally been looked to as 

 a route by which they may be avoided. Hitherto no chart has 

 existed in which much confidence could be placed ; but by the 

 present survey, the navigation through it, independent of wind 

 and weather, has been rendered much easier; since a correct 

 delineation of its shores, and plans of the anchorages, have 

 been made ; and in the preceding pages, sufficient descriptions 

 of them have been given to assure the navigator of his place, 

 and furnish him with advice as to his proceedings. The local 

 difficulties therefore have been removed ; but there remain much 

 more serious ones, which I should not recommend a large, or 

 even any but a very active and fast-sailing square-rigged 

 vessel to encounter, unless detention be not an object of im- 

 portance. 



For a square-rigged vessel bound through the Strait, the 

 following directions will be useful : —
