Preserving Green Forage 15 



no fermentation in the silo, the forage does 

 not heat up and pass through the alcoholic 

 and acetic fermentation to lactic and putrid, 

 but sometimes takes on a mouldy condition, 

 which develops black rot and causes destruc- 

 tion in that way. This may be called fermen- 

 tation, but it is not a true fermentation. 



That I have succeeded, after years of study 

 and costly experimenting, in perfectly remov- 

 ing air from the silo, preventing heat and 

 fermentation, and Preserving Green Forage 

 Corn in perfection, will be demonstrated in the 

 following pages. 



OF SILOS. 



A really good silo must be tight and strong 

 and impervious to air and water. It should 

 have a good foundation, perfectly drained and 

 perfectly perpendicular, smooth, level-faced 

 walls. If these conditions are fulfilled, it is 

 not very material of what they are made ; but, 

 when made of masonry, all forms of lime must 

 be excluded, as acetic acid dissolves the lime. 

 Cement must be used instead of lime mortar. 



Good silos are somewhat expensive ; but 

 true economy points in the direction of dura- 

 bility, convenience and assured success. Their
