A FORCE-FEED GRIT-HOPPER. 



Invented by James E. Rice and R. C. Lawry. 



Recent experiments at the college have proved that both lime and 

 grinding material are required by fowls for best results in health and 

 production. It is essential, therefore, that fowls have access to cracked 

 oyster shells at all times. It also appears to be desirable that some other 

 form of grit be provided, and perhaps charcoal. For this purpose a 

 grit-hopper large enough to make frequent filling unnecessary, so con- 

 structed that it will be kept clean, cannot clog or waste, is necessary. 

 The grit-hopper here shown accomplishes the above results. (Figs. 91 

 and 92.) Its distinguishing feature is the rounded back which compel.= 

 a forced-feed. (Fig. 92.) The cost should not exceed $1.
