COCOA AND CHOCOLATE 



J. S. Fry and Sons, Limited, for information and 

 photographs. In one or two cases I do not know whom 

 to thank for the photographs, which have been culled 

 from many sources. I have much pleasure in thanking 

 the following : Mr. R. Whymper for a large number of 

 Trinidad photos ; the Director of the Imperial In- 

 stitute and Mr. John Murray for permission to use 

 three illustrations from the Imperial Institute series 

 of handbooks to the Commercial Resources of the 

 Tropics ; M. Ed. Leplae, Director-General of Agri- 

 culture, Belgium, for several photos, the blocks of 

 which were kindly supplied by Mr. H. Hamel Smith, 

 of Tropical Life ; Messrs. Macmillan and Co. for five 

 reproductions from C. J. J. van Hall's book on Cocoa ; 

 and West Africa for four illustrations of the Gold 

 Coast. 



The photographs reproduced on pages 2, 23, 39, 

 47, 49 and 71 are by Jacobson of Trinidad, on pages 

 85 and 86 by Underwood & Underwood of London, 

 and on page 41 by Mrs. Stanhope Lovell of Trinidad. 



The industry with which this book deals is changing 

 slowly from an art to a science. It is in a transition 

 period (it is one of the humours of any live industry 

 that it is always in a transition period). There are 

 many indications of scientific progress in cacao cul- 

 tivation ; and now that, in addition to the experimental 

 and research departments attached to the principal 

 firms, a Research Association has been formed for the 

 cocoa and chocolate industry, the increased amount of 

 diffused scientific knowledge of cocoa and chocolate 

 manufacture should give rise to interesting develop- 

 ments.
