THE EXERCISER. 



157 



In a large establishment, where an attendant must 

 be on hand pretty much all the time, anyhow, this oper- 

 ation by a crank will be chosen, but the fancier or 

 amateur, or ordinary keeper of one or a few flocks, will 

 do well to attach clockwork to the dropper, and to the 

 chaff box described further on, so that the feeding may 

 be carried on regularly, while he is at his office or store 

 or even out of town. The easiest way to make a crank 

 and attach it to the axle of the dropper, is to use a half- 

 inch iron pipe six inches long and another piece four 

 inches long for a handle, and two elbows, one of which 

 is to be screwed to one end of the axle, see Figs. 120 and 



63. Or, if a black- 

 smith can be obtain- 

 ed more readily than 

 a plumber, one end 

 of the hollow axle 

 may be plugged with 

 iron and a wrought 

 iron crank, Figure 

 67, may be attached 

 with a nut and 

 washer. Or a ready 

 made crank with a 

 wooden handle, Fig. 

 69, can generally be 

 procured at a hard- 

 ware store. Or, if 

 you are near an ag- 

 ricultural implement 

 factory or a railroad 

 shop and can get a handwheel, such as is represented in 

 Fig. 68, it will be better than any sort of crank.
