 such as Dadaps (Erythrina) and Albizzia, which 

 can be easily controlled. It is still, as we have 

 said, an open question whether the provision of 

 any shade at all is advisable in Uganda, but until 

 this has been decided it is perhaps the safer course 

 to provide it. In opening a new field for Cocoa

 months before the Cocoa. 



Wind-belts. Amongst Para and Coffee wind- 

 breaks will be found of the greatest use. The 

 extent and frequency of these must depend upon 

 the force of the prevailing winds. In Para fields 

 they will only be a temporary institution whilst the 

 trees are young. In such a case the Ceara Rubber
