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 may be 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 
inabay. 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.
