navigable. From Lat. 40 to 50 (when near the coaft) the fea 

 If often runs i till higher, meeting the tide from the (hoar, but I do 



not mean to raife too great apprehenfions on this account. 



At the diftance however of 100 leagues from the coaft the feas 

 are often ftill heavier ; fo that I would advife lying to, if the 

 wind is not favourable. 



From 50 degrees upwards the feas rife proportionably with 

 the winds, particularly if they blow from the S. or S. W. but 

 foon become calm when the weather clears. 



[Here follow fome obfervations, with regard to the effect of ' 

 the moon upon the weather, which I mail not tranflate, as the 

 influence of this planet in fuch refpect feems now to be much 

 exploded.] 



As approaches to the coaft ought always to put the navigator 

 OH his guard, he may depend upon the following figns for its not 

 being far diftant. 



When the coaft is about 80 or 90 leagues to the E. thole 

 fea- plants appear which I have before called Orange heads; but I 

 muft now add, that from the ftate of them, as they float, one 

 may fometimes infer, that the land is not fo far diftant. 



Its figure much refembies the fiftular ftalk of garlick e ; and 

 from the top of its head hang fome long leaves, by which the 

 plant is fixed to the rocks. Now if thefe leaves are tolerably 

 perfect, they afford a ftrong prefumption, that they have not 

 floated far from the coaft. On the contrary, thofe which have 

 been wafted to a confiderable diftance, have generally loft this 

 head, and the ftalk becomes more rough, when you may fup- 

 pofe that you are 50 leagues from the land. 



e The appearance of this plant on the coafc of California, is noticed in 

 Lord Anfon*s Voyage.
