64 The Cultivation and Preparation of Coffee

 and he should then turn each adjusting hand 

 wheel to the left, giving same a quarter- to 

 half -turn to each wheel, in order that the depth 

 of each channel would be as nearly equal as 

 possible, and vice versa if the pulped coffee is 

 delivered with any signs of scratching. The 

 adjustment of the breast and its channels 

 should be very carefully effected, as by exercis-
