 escape of the pulp, but the utmost care must be

 broken coffee among it : should there be any, an 

 improper space must exist somewhere, probably 

 between the lower chop and the cylinder, or at the 

 ends of the chops next the framework of the 

 machine. 



Since 1865, coffee-pulping machinery has been 

 much improved, and planters can now pulp their 

 coffee without having to reckon on a serious per- 

 centage being cut or pricked by the pulper. Greater 

 care is taken to feed regularly than was customary 

 before, and simple arrangements for this purpose 

 have been very successful. The improvements have 

 mostly been in the direction of construction and in 

 turning the cylinder and disc pulpers to better 

 account, no pulper on a new principle having come 

 into general use. Cylinders and discs for pulpers 

 are now almost invariably made of solid iron (instead 

 of wood, as formerly), turned fair and then covered 

 with punched brass or copper. This insures per- 

 fectly circular and plane cylinder and disc sur- 

 faces, obviating the inconvenience which used to 

 sirise from the warping of the woodwork in the old 

 machines. Frames entirely of iron have also been
