2io COFFEE: ITS CULTIVATION AND PROFIT. 



which should be obtained there on the most advantageous 

 terms. There is no better manure for Coffee than one-third Bengal 

 saltpetre and two-thirds patent superphosphate. As, however, sul- 

 phate of ammonia is at the present moment remarkably cheap,, 

 it might answer to have a mixture made of superphosphate, 

 sulphate of potash, and sulphate of ammonia in equal proportions. 

 This would make a very concentrated manure, and would 

 give satisfactory results. The prices of these ingredients are 

 as follows :

" All manures for Coffee contain, or should contain, the 

 above suggested ingredients ; and the proportion we recom- 

 mend is based upon the constituents of the plant, and which 

 would probably give the best result upon the land." 



Artificially-prepared manures, it may be gene- 

 rally said, are more stimulating in their action 

 than likely to do permanent good. They require 

 for their economical application considerable study 

 of the character of the soil and knowledge of the 

 history of previous manurings that may have 

 been carried out, " For pulling a crop through,, 

 or putting wood on trees deficient in leaf, such 

 manures as sulphate of ammonia in small quanti- 

 ties may sometimes be used with success," remarks 

 Mr. W. D. Bosanquet ; and Mr. Henry Tolputt, 

 the observant manager and courteous director r 

 holds that " ammonia, phosphoric acid, and potash
