 axle should not be over 50 or 

 60 ft. long, for if too long it 

 will "give" or twist too much. 

 To aid readers who prefer 

 something simpler than the feed 

 cylinder previously described for 

 dropping grain, illustrations of 

 a feed pouch are given. Figure 

 89 shows wire cloth of different 

 sizes of mesh, Fig. 58, nailed to 

 end pieces of wood forming a 

 sort of pouch, the whole being 

 nailed to a square stick which 

 serves as an axle, this axle being, 

 of course, rounded at the bear- 

 ing places, which are not shown 

 in the cut. The narrow board 

 in the foreground is at the side 

 where the grain is put into the 

 poach, the attendant going the 

 rounds with a pail of grain in 

 one hand and a scoop in the 

 other, this board answering the 

 same purpose as the flange of 

 tin, a, in the cylinder, Fig. 60, 

 and the board, like the flange, 

 is set flaring, to facilitate charg- 

 ing with grain. Such a pouch 

 can be used indoors over a tilt 

 box, or out of doors over a pen 

 in the out-of-doors exerciser, and the shaft may be 3x3
