 berries are often seen on the trees at the same time ; and, 

 as the flowering frequently comes on before the crop is 

 gathered, the planter is often bothered a great deal, for, as a 

 rule, the trees must not be interfered with at all whilst they 

 are flowering.

 able situations and under proper cultivation some trees will 

 yield much more. The Liberian coffee trees are much more 

 prolific than the Arabian kind, and each tree yields from one 

 to eight pounds of clean coffee. About three bushels of Ten pounds of

 the pulp of Liberian coffee is much thicker, and the berries 

 of this kind will not give so much clean coffee to the bushel ; 

 but the trees, by bearing larger crops, compensate for the 

 greater loss in pulp. 



PULPING. The operation of removing the pulp from the Bernes^^ 

 berries sometimes wrongly called "cherries" is termed 

 pulping, and it may be done by the hand, by pounding 

 the fruit in a mortar, or by pressing the berries with a roll- 

 ing motion between two flat boards. These methods, how-

 be treated, and, on a large scale, a machine called a pulper Machinery.

 is that of a roller covered with a copper grater, and made 



; to revolre against a smooth surface, the chop. The grater 

 is approached so closely to the chop that the berries will be 

 crushed without the coffee bean and its parchment covering 

 being injured ; and, as the chop is moveable, it can be set Mocha 

 to the different sizes of the beans. Thus in pulping Mocha coffee.
