THRESHING WITH SPECIALLY EQUIPPED SEPARATOR 1 93 



round-hole wheat sieve, H, works very well in "Whip- 

 poor-will" stock-peas. 



If trouble be experienced because the peas strike the 

 floor of the shoe and bound over into the fan, it can be 

 prevented by covering the front part of the chaffer to a dis- 

 tance of twelve or fourteen inches with sheet-iron. If 

 there be much sand or dirt to be screened out, applying 

 the same remedy will cause the peas to be dropped farther 

 rearward and allow the dirt more chance to get through 

 the screen. Returning peas to the cylinder with the tailings 

 is apt to crack them, and, therefore, the cleaned peas will 

 contain fewer split ones if the tailings be kept separate. 

 This may be done by opening the bottom of the tailings- 

 elevator and allowing them to run on the ground or on a 

 canvas. Afterwards they may be run through the ma- 

 chine while "cleaning up." 



Threshing Beans. All that has been said above, in 

 regard to threshing peas, applies equally well to threshing 

 the ordinary white navy beans, and also the larger varie- 

 ties, except, that for the latter, if common sieves be used, 

 the three-quarter-inch lip, F, should be used in place of 

 the three-eighths-inch lip sieve, G, in the shoe. 



Threshing Soy Beans. Soy (or soja) beans are diffi- 

 cult to knock out of the pods, and are so hard that they 

 are not easily cracked. Therefore, they can best be 

 threshed with a separator adjusted and speeded as for 

 wheat. Soy beans sometimes grow quite rank, often yield- 

 ing from 25 to 40 bushels of seed and 12 or 13 tons of fod-
