coffee among which they may be planted ; pro- 

 bably in hot climates, and for the first few years, 

 until Jack-trees have had time to grow up, they 

 might prove useful. 



Trees for shade should not be sufficiently near 

 each other to prevent a free circulation of air, or 

 entirely to exclude the sun's rays, a certain amount 

 of both being necessary to produce vigorous coffee. 

 They may, however, in hot situations, be grown 

 tolerably close together in the first place, it being 

 easy to thin them out to the required extent 

 afterwards, as they increase in size. In order to 

 make the trees throw out wide leafy heads, and 

 thus form a sort of natural canopy or awning over 

 a large space, they should be trained to single 

 stems till ten or twelve feet high, all lateral 

 branches being kept off. This system will also 

 tend to produce large straight timber (which is a 

 consideration to be kept in view).
