THRESHING WITH SPECIALLY EQUIPPED SEPARATOR. 169 



Threshing Indian-Corn or Maize. The threshing of 

 Indian-corn is very hard on a separator and the use of a 

 good machine for this purpose is therefore not recom- 

 mended. Some threshermen use a separator which has 

 been discarded for use in regular grain threshing and this 

 arrangement is not objectionable. As the corn is shelled by 

 the machine it must be drier than is necessary for a husker- 

 shredder, or the shelled corn will heat and spoil. Usually 

 the cylinder is run at its normal speed and two rows of con- 

 cave-teeth are used. Often concave-teeth are forged so as 

 to be sharpened on the front edge or else shortened to 

 lessen the amount of power required to drive the cylinder. 

 The fish-backs may be removed from the straw-rack and 

 the risers lowered so that the rack is flat, similar to the 

 special "Texas" rack used for Kafir-corn. 



Threshing Peanuts. Although a great part of the pea- 

 nut crop has always been removed from the vines by hand, 

 machines are being used more and more each year for this 

 work. The "Case" separator, when fitted with special parts, 

 works very satisfactorily, and the separation is more com- 

 plete with it, than with the machines built especially for 

 hulling peanuts.
