52 PLANTS, SEEDS, AND CURRENTS 



Madeira and the Canary Islands, and after approaching the vicinity 

 of the Cape Verde Group it would get into the full stream of the 

 North Equatorial Current, and thus be borne to the West Indian 

 region. Whilst, as already indicated, the conclusions for the first 

 portion of this circuit are mainly based on the American charts, 

 those for the remainder are also founded on the Prince of Monaco's 

 results. With these introductory remarks I will first deal with the 

 traverse of the North Atlantic by drift from the American to the 

 European side of the ocean, and afterwards with the return passage 

 from European and African waters to the West Indian region. 



The Passage of Bottle-drift from the West Indies and the East Coasts 

 of North America to the Shores of Europe 



TABLE I 



The traverse from the West Indies to the shores of Europe 



(Compiled from the American, German, and English sources above named. The 

 columns A, B, C, D, indicate not only the starting-places of the bottles, but also 

 the track pursued by them in the passage from the New to the Old World. The 

 circuit of the North Atlantic is also illustrated by those bottles, which, on approach- 

 ing the shores of Europe, were deflected south, and after passing through the Canary 

 Islands, were returned to the West Indian region in the North Equatorial Current.)
