Cook {U.S.A. Dep. Agr., Div. Bot., U.S. Nat. Herb. vol. vii. No. 2; 

 1901). — The current opinions and popular inferences as to its origin and 

 distribution are given. The improbability of Spanish introduction is 

 ably discussed, together with early Spanish accounts of the Cocoa Palm 

 in ancient America, and methods of its introduction to the Atlantic 

 coasts. The American names of the Cocoa-nut are given, with botanical 

 evidence and prehistoric introduction of other plants, thus tending to 

 prove the Cocoa Palm an American species. 



The dissemination of the Cocoa Palm with the origin of its varieties 

 and failure of maritime distribution in Australia point to the ineffective- 

 ness of ocean currents, thus rendering human assistance in some form 

 necessary. 



The original habitat of the Cocoa Palm, with the direction of the 

 trans-Pacific distribution, is followed by a summary of De Candolle's 

 arguments from which conclusions are drawn. — E. F. H.
