adjustable one. For this purpose, the three-thirty-seconds- 

 inch round-hole sieve, N, or the twelve by twelve mesh 

 woven-wire-sieve, R, is the correct size. Either should be 

 placed in the seventh notch and eighth hole. The adjust- 

 able shoe-sieve should be placed in the second notch and 

 third hole. When common sieves are used, the three-quar- 

 ter-inch lip, F, makes a suitable chaffer, and the three- 

 eighths-inch lip sieve, G, is the best as an upper sieve in 

 the shoe. The latter should be placed in the first notch 

 and first hole and the lower shoe-sieve should be of the 

 same size and placed in the same position as given for 

 adjustable-sieves. It is possible to use three sieves in the 

 shoe, but it is doubtful whether cleaner seed can be pro- 

 duced with three than with two. These directions for 

 sieves apply to all the common varieties of clover, such as 

 the red, alsike, white, etc. For extra large seed, such as 

 that of the German or crimson variety, a coarser sieve (say 

 the three-thirty-seconds-inch round hole, N), may be sub- 

 stituted for Y. For the Japan variety, the one-eighth 

 round hole, O, may be used. 



In localities where clover seed is threshed in consider- 

 able quantities, the "Case" clover recleaner may be used 

 and it will thoroughly clean very weedy seed. This re- 

 cleaner is attached to the left hand side of the separator 

 just back of the grain elevator. It is driven by means 

 of a special double pulley on the separator fan-shaft with 

 a straight belt.
