 This is to be accomplished by removing the 

 air from the silo w r hile filling and after it is

 teria of fermentation and decay are conveyed 

 from place to place. To prove his theories, 

 he built a new silo in the spring, and con-

 racy that we give an illustration of the appear- 

 ance of things when the silo was under way, 

 in order to emphasize the care that was taken 

 to get accurate results. The picture, made 

 from a photograph, shows the framework and 

 the walls of the silo just beginning to rise. 

 The silo is 32 x 12, 20, with the cement walls
