THE EARTH'S BOUNTY 



When the more elaborate building, like the 

 Wisconsin, or brick-lined silo, is selected, it is 

 imperative to provide ample ventilation for 

 the spaces between the studs, as well as for 

 the roof and the inside of the silo. Between 

 each pair of studs, where needed, a l^-inch 

 auger hole, to admit air, is bored through the 

 siding and sheeting, and covered with a piece 

 of wire netting, to keep out mice and rats. At 

 the top of the silo on the inside, the lining is 

 only covered to within two inches of the plate, 

 and this space is covered with wire netting, 

 to prevent silage from being thrown out when 

 filling. This arrangement permits dry air 

 from outside to enter at the bottom between 

 each pair of studs, and to pass up and into the 

 silo, thus keeping the lining and studding dry, 

 and at the same time drying the under side of 

 the roof and the inside of the lining as fast as 

 exposed. In those cases where the sill is made 

 of 2 X 4's, cut in 2-foot lengths, there will be 

 space enough left between the curved edge of 

 the siding and sheeting and the sill for air to
