 the various sizes of beans and waste material that is 

 required to be removed from the best samples. The 

 apparatus is shown in Fig. 56. It consists of a cylinder

 the cylinder is furnished with a worm which gently moves 

 the cacao beans along the cylinder, thus ensuring even and 

 perfect grading. The machine can be built with any 

 number of divisions, so as to grade as may be desired. 

 The produce is inserted at A, and delivered under five 

 separate classifications. At B, grit, dirt, &c., or Passe ; 

 at C, thin flat beans ; at D, small-sized beans ; at E, 

 medium-sized beans ; and at F, large-sized beans ; all 

 of which have their different markets, the ultimate desti- 

 nation of the very lowest qualities being often somewhat 

 of a mystery to the grower. 



Coco-nut matting is never used in Trinidad for drying 

 cacao.
