3 io Coffee Planting. 



when weeding, &c. Then, the ground can be pro- 

 tected from being burned up by the sun, by plant- 

 ing the trees sufficiently close to form a good cover, 

 and from exhaustion otherwise by systematic weed- 

 ing ; while, obviously, exhaustion by cropping can 

 only be remedied by substantial mamtring. 



It will perhaps be objected that my chapter on 

 that subject does not lay sufficient stress on the 

 value of those manufactured fertilizers which the 

 advance of science has of late years brought within 

 our reach ; and, as a practical planter, knowing the 

 dislike of practical planters generally to all that 

 seems to savour of mere theorizing, I may not 

 improbably have erred in this direction, as much 

 as a practical chemist, in treating of the same 

 subject, might have been inclined to do in the 

 opposite one. Chemical manures, however, must 

 by no means be lost sight of: indeed, where 

 judiciously made use of, in composts and in 

 conjunction with the produce of the cattle-shed, 

 the refuse of the bungalow, lines, &c., and even 

 with merely green vegetation, they will be found 

 invaluable. Of late years chemistry, like every 

 other branch of science, has made immense strides, 

 and fertilizers carefully compounded in accordance 

 with the chemical analysis of the product to be 

 grown, are specially manufactured to an enormous 

 extent for every species of cultivation.
