 in the East has attained during the past few years must be my 

 excuse for offering to my fellow planters an English translation of

to translate a German scientific work literally without rendering 

 the translation heavy and un-English, though I have endeavoured

 " Tropenpflanzer " for allowing the publication of an English 

 version. Mr. F. Crosbie Roles, of Ceylon, has kindly helped me 

 to see this pamphlet through the press.
