Les plantes tropicales de grande culture. The author se- 

 lected for thorough discussion coffee, cacao, kola nuts,

Willis, J. C - 



Agriculture in the Tropics. This is a small handbook deal-

Woodrow, G. M. 



Gardening in the Tropics. In this volume the garden crops, 

 fruits, ornamentals, and incidentally other economic crops 

 are treated from the viewpoint of the tropical farmer. The 

 first edition considered only the conditions in India, but the 

 revised edition is broadened in its point of view. (Paisley: 

 A. Gardner, 1910.) 



PERIODICALS RELATING TO TROPICAL AGRICULTURE 



As will appear from the following list of periodicals, which 

 deal for the most part exclusively with tropical agriculture, the 

 number of such publications is quite large. It should be remem- 

 bered that this list contains by no means all of such periodicals, but 

 only those which may be of particular interest to students of the 

 general subject. In addition to the periodicals listed below, one 

 must remember that there are large numbers of journals in which 

 tropical products are discussed along with other farm products. 

 Such journals would include periodicals on paints, oils, perfumes, 

 drugs, tans, dyes, fibers, etc.
