Mr. Ridley's book is a practical work intended for the use 

 of planters in all parts of the world. In it the reader will 

 learn about the soils suited for the various spices, the diseases 

 from which the plants suffer, the most efficacious insecticides 

 and fungicides, the different kinds of manure to be used, and 

 indeed everything connected with this branch of agriculture. 



NATURE. "A book of this kind must appeal mainly to 

 planters in the tropics, and Mr. Ridley's extensive experience of the 

 needs of this class of readers has enabled him to produce a volume 

 which is a valuable addition to the rather scanty literature of 

 tropical agriculture." 



ECONOMIST. "Mr. Ridley's book, besides giving a great 

 deal of interesting historical information, contains much valuable 

 technical and statistical matter, which renders it of great use both 

 to the planter of spices and to the student of commerce."
