of the Tropical World.

Separate complete sections are included in this work, devoted 

 to Ceara, Castilloa and Funtumia rubber cultivation and their 

 tapping and preparation for market. The Foreword is by 

 Professor Wyndham Dunstan, C.M.G., F.R.S., &c., Director of 

 the Imperial Institute and President of the International 

 Association for Tropical Agriculture (Association Scientifique 

 Internationale d'Agronomie Coloniale et Tropicale) and in- 

 cludes an eloquent but eminently practical appeal based on 

 plain, common-place facts, for the establishment of Agricultural 

 Colleges in the Tropics, where research work can be carried 

 on and men trained as " plant-doctors," estate-owners, and 

 managers, &c., in order to assure larger returns from the 

 areas planted than we have hitherto been receiving. 



The book has been warmly welcomed on all sides, and 

 been favourably commented on in the Press both on this side 

 as well as throughout the Tropics.
