70 .The Cultivation and Preparation of Coffee 



draining plate somewhere near the " patio," or 

 drying ground. 



Before going any further I may mention 

 that in places where there is a scarcity of water 

 the use of the Okrassa Patent Coffee Washer 

 will be very convenient, because this is the 

 washer considered to utilise the minimum of 

 water to wash the coffee, also the well-known 

 Vertical Washer is largely employed. This 

 machine, however, works by charges, being 

 capable of washing twenty-five cubic feet of 

 fermented coffee in about ten minutes. 

 The Vertical Washer has an advantage over 

 the others, since it separates the " natas " 

 or light coffee, from the sound beans. 

 " Natas " is the term given in Central America 

 to coffee, which in appearance when in parch- 

 ment is just about the same size as the sound 

 coffee, the beans, however, not having reached 

 their full development.
