" Those owninjT established plantations, or who are thinking of taking up 

 cocoa-planting as an industry, will certainly need to add Mr. Johnson's work 

 to their book-shelves, and when they do so they will find the information given 

 to be compact, easy to understand and follow, sound in practice, and reliable 

 in detail. We are glad to see such a book from so experienced an authority."

 valuable handbook of one of our chief colonial industries." — N^orthei-n Whig.
