the end piece, Fig. 61. In 

 Fig. 60, a represents the tin 

 which is tacked closely at 

 the bottom of the cylinder, 

 but flares out into a flange 

 at a. Above a, there .is an 

 open space, through which 

 the cylinder is charged with 

 grain. The flange assists in 

 putting in the proper quan- 

 tity quickly, the grain slid- 

 ing down, of course, so as to 

 rest on the tin at the un- 

 derside of the cylinder. In 

 Fig. 60, the cylinder is shown 

 in correct position for fill- 

 ing. The cylinders are fast- 

 ened to the shaft so as to 

 move with it, not on it. 

 The grain should be in the 

 form of small particles of 

 assorted sizes, from the di- 

 mensions of a pinhead to a 

 kernel of wheat. Cracked 

 corn with the meal sifted 

 out is excellent. 



The cylinder should be 

 made to perform only about 

 a hundredth of a revolution 

 at a time, the motion, at 

 first, after charging with 

 grain, being in the direction 

 to raise the tin upward, con- 

 sequently the millet, wheat 

 and cracked corn will come 

 in contact first with the fine
