DIGESTION EXPERIMENT 56 — (MIXED SILAGE.) 



Material used: Silage made of mature flint corn, horse 

 beans and sunflower heads, cut and put in the silo in the pro- 

 portion of one acre of corn, one-fourth acre of sunflower heads 

 and one-half acre of horse beans. This mixture was first 

 recommended by Professor Robertson of Canada, and so far as 

 the writer is aware, this is the first digestion experiment that 

 has ever been made with it. The material was perfectly pre- 

 served in the silo and readily eaten by the sheep. The results 

 of the experiment are given in the following tables:
