 when it is built, and these project enough above 

 this to jusb extend through the sills to permit 

 capping with washers and nuts. 



Roof. — A roof is required only on silos out of 

 doors. This may be built to suit, but it should 

 at least protect the silage from rain and snow. 

 It should, if of permanent character, contain a 

 dormer window or door in roof through which 

 the elevator may carry the cut fodder and de- 

 posit it within the silo. 



Capacity of silo. — The capacity of the silo 

 depends on the needs of the farmer. A cubic

foot of silage under average conditions will 

 weigh 40 lbs. — perhaps a little less. A day's 

 feed for one cow would not probably as a rule 

 exceed this amount. If silage is fed one cow 

 200 days she will consume, say 8,000 lbs., or 

 four tons. On this basis 10 cows will require 

 40 tons, though it would be well to make the 

 capacity 50 tons.
