THRESHING WITH SPECIALLY EQUIPPED SEPARATOR 197 



as for oats. Rice is considerably heavier,* however, and 

 will stand the extra amount of wind required to blow out 

 its heavy chaff. When common sieves are used the chaffer 

 should be the two-inch lip, D. The three-quarter-inch lip- 

 sieve, F, placed in the second notch and third hole gives 

 excellent results as a shoe-sieve. For a screen, the one- 

 fourteenth by one-half-inch oblong-hole, L, is best, ordi- 

 narily. When the rice is so small that this screen lets too 

 much through, the one-sixteenth by three-eighths-inch ob- 

 long-hole, K, may be used.
