Preserving Green Forage 73 



rows of %-inch holes in the pipes and the 

 openings between the top plank, giving ample 

 opportunity for the escape of gas. In this way, 

 while filling a silo of this size, in four days, I 

 had 6 inches of juice in the bottom before I 

 could get the cover on or give it any pressure; 

 while other silos, having no governors, had no 

 juice upon their bottoms, even when weighted 

 with from 100 to 200 pounds to each square 

 foot of top surface. By this system, it does 

 not require one-half the weight or pressure to 

 secure the ordinary results gained in the man- 

 agement of silos ; and I am led to believe there 

 is no other way known as yet to prevent heat 

 or fermentation, or one likely to be devised as 

 perfect and economical as this.
