in. or 4x4 in., or any size demanded by its length and 

 by the number of pouches fastened to it. 

 The pouch may be two or three feet long, 

 and the width of the end pieces must, of 

 course, suit the size of the shaft. 



A still simpler style, and easier to con- 

 struct, shown in Fig. 110, goes well with 

 the rough pole. The projecting bottom 

 piece gives a sufficient surface to nail 

 through. A flange board similar to that 

 in Fig. 89 may be easily added, if desired. 

 If the distant out-of-doors feed pens, such 

 as are shown at B, in Fig. 83, are fitted 

 with such a pole and pouches, no spool 

 need be used, but a wire and weight can 

 be employed, the same exactly as in Fig. 

 84, the big end of the pole serving for a 

 spool. 



If rounded bearings are to be made for 

 w a square shaft of a row of tilt boxes, or 

 % for a square shaft of a row of feed pouches 

 I or feed cylinders, then it will not be found 

 a good plan to cut away the square cor- 

 ners of your wooden shaft, because it 

 gg weakens it. Build onto it, instead, by 

 o simply nailing on rounded bearing pieces 

 fe like that shown in Fig. 90. Figure 91 

 gives a transverse section of a shaft or 

 axle, c, with four such pieces attached, a, 

 on which the axle turns. The rounded 

 bearing pieces may turn in a notch either 

 square or rounded, cut in a horizontal 

 stick and overlaid with tin, as previously 

 mentioned. 



A square wooden shaft for out-of-door 

 feed boxes may be attached to the spool on
