288 FEEDING FARM ANIMALS 



Hollow Clay Blocks. The latest development 

 consists of the use of hollow clay building blocks. 

 These are easily erected by an expert mason, and 

 are successful if properly reinforced by wire be- 

 tween the various courses of tile. Being built of hol- 

 low tile, there is less freezing of the silage on the 

 inside than where the walls are made of brick or 

 solid concrete. The freezing, however, is generally 

 of little importance. 



Not every farmer needs a silo, but every farmer 

 who keeps a herd of six or more cows, dairy or beef, 

 or 50 sheep, will find the silo a profitable addition to 

 his farm equipment. More feed can be obtained 

 from an acre of corn saved in the silo than in any 

 other way. It is possible to make more and cheaper 

 milk, beef and mutton by feeding silage than with- 

 out it.
