INTRODUCTION 



THE tropics include an immense area of land in every 

 continent but Europe. Their agriculture, however, was until 

 lately only of serious importance to the world at large in 

 Southern Asia, Brazil, Mexico, Central America and the West 

 Indies, West Africa, North Australia, and a few groups of 

 islands in the Pacific. The following rough figures, giving in 

 round numbers the value or bulk of the chief exports from 

 some of the principal exporting countries, will give some idea 

 of the enormous trade that now goes on, and which is increasing 

 year by year.
