PULPING AND PREPARING. 175 



obtained. The " Double " Pulper of the same 

 firm is more complicated, and being, consequently, 

 liable to breakdowns, can only be recommended 

 where an engineer is at hand in case of a mishap ; 

 but their " Combined Coffee Crusher and Pulper" 

 is of excellent design. The cylinder is stoutly 

 cased with copper, and the machine is provided 

 with water hopper and sieve. By addition of the 

 crushing roll, the pulper is rendered more expe- 

 ditious in operation, and will deliver without 

 damage to the beans from 100 to 120 bushels of 

 cleanly-pulped Coffee per hour. This pulper is 

 adapted for mill work only, and is unsuited for 

 manual labour, being driven by leather belt from 

 shafting connected with water or other power. 



But though with good machinery, such as the 

 above, even a new hand can generally save a 

 crop in marketable guise, yet pulping is not always 

 the simple work it may seem. " Successful pulp- 

 ing," we are told, " depends greatly on the dryness

may all be plump and ripe,_ when jpulpers will 

 easily work through 90 to 100 bushels per hour, 

 having plenty of water to run into the machines 

 with the Coffee ; the next season may be a dry 

 one, and the trees bearing heavily, very few of the 

 berries become fully ripe. Now the difficulty of 

 pulping commences, the pulp adhering to the 

 parchment owing to the absence of saccharine 

 matter. Should the pulper be 'set close/ it will
