Preserving Green Forage 85 



silo can be filled with green vegetable matter 

 without eliminating heat. Any succulent vege- 

 table matter piled together in the presence of 

 air commences to heat. If allowed to go on, 

 destructive fermentation sets in, and at length 

 the whole mass becomes putrid and rotten. 



ELIMINATING THE AIR. 



The various means heretofore used have only 

 measurably arrested this fermentation, and the 

 measure of success has been in just proportion 

 to the exclusion of the air. Not until the in- 

 vention of Mr. Colcord, a retired druggist of 

 Dover, Mass., have we had means of governing 

 this fermentation at will, or in time to prevent 

 more or less destructive fermentation. The 

 means used by him was the result of scientific 

 study, through his knowledge of chemistry and 

 chemical action.
