larger quantity of silage to be put in, but it expels 
at once a very large volume of air, which, if 
allowed to remain, prolongs the changes. It should 
be tramped well around the sides because the 
lateral pressure of the silage tends to develop fric- 
tion against the walls, which prevents its settling. 
In building a silo, it should be as deep as it is 
practicable to make it. The advantages of a deep 
silo are that the largest quantity of feed per cubic
