 successively, all the time losing grain of a coarser size, the 

 coarsest particles of the whole falling through the open 



space next to the 

 flange, a, by the time 

 the cylinder has made 

 a complete revolu- 

 tion. The operation 

 of revolving a cylin- 

 der and its succes- 

 sive positions are 

 plainly shown in 

 Figs. 92,93,94 and 95.

This shaft of half-inch iron pipe must have a hole drilled 

 through it to receive a common wire nail, as shown in 

 the left of Fig 60 ; the nail being clamped against the 

 wood by means of small staples. 



At one end of the shaft or axle, attach a crank, which 

 must be moved only the very slightest distance at a time, 

 so as to spill the desired quantity at a dose into each pen 

 of birds located under each cylinder, and supplied with 

 straw, chaff, or litter, upon which the feed drops. 

 Eight or ten hours or so must elapse before you make 

 the axle accomplish a complete revolution. In a frac- 

 tion of a second you can sift down a dose for a half 

 dozen flocks or for a score of flocks, according to the 

 length of the building and the axle. It takes no longer 

 to feed several hundred birds than to feed twenty. A 

 mere jar with the thick of the hand against the handle 

 of the crank does the business. This jar should be given 

 two or three times an hour.
