SILOS AND SILAGE. 193 



dressed face. The purpose of this is to enable 

 the silage to settle evenly. No blocks or rods 

 should interfere with the settling process. 



There should be as few corners as possible, 

 for it is in corners, at the door casings and on 

 the surface that the most silage spoils. Con- 

 sequently a round silo offers advantages over a 

 square or rectangular one. Corners may be 

 boarded off and the angles reduced. Door 

 boards should fit smooth and flush with the 

 side of the silo. 



Gas. tar maybe profitably painted over all 

 woodwork, for as a preservative it is of the 

 highest character. No wet or green wood 

 should be used, and only the dry timber be 

 tarred. This material can be applied to best 

 advantage when hot. 



Most desirable forms. — The two most de- 

 sirable forms of silos are round and square. 

 The round contains the least amount of waste 

 space, and owing to its form -of construction 

 presents more strength to resist side pressure 

 than any other shape, as it is equally distributed 

 against the walls at every point. 



The square or rectangular silos may be often 

 built to advantage in the barn, in a corner or 

 in a bay. If to be built to stand by itself the 

 square form is preferable to the rectangular. 

 The walls are stronger. For equal capacity 

 there is less waste wall space in the square.
