It is not advisable to build a silo more than 16 feet in diameter, and it 

 is better to have two small silos than one too large. 



The height above the foundation should be at least twice the inside 

 diameter. The tons of silage required indicate the height, and they depend 

 on the period for which food has to be provided. The average weight of a 

 cubic foot of matured silage may be taken as 40 It>. One ton accordingly will 

 take up 50 cubic feet, and 300 tons, 5,000 cubic feet. During six months, 

 or 180 days, ten cows, each consuming 40 lt>. daily, would require 36 tons of 

 silage, which is contained in 1,800 cubic feet.

The foregoing figures refer to matured silage which has settled thoroughly. 

 To obtain 30 feet of this, the silo must be about 34 or 35 feet high to allow 

 for the settling. This process takes place more completely and the silage 

 keeps better in silos 30 feet high than in shallower ones. The loss of food 

 material that takes place in the manufacture of silage is from 5 to 10 per 

 cent. If 90 tons be needed, it is therefore necessary to place about 100 tons 

 of corn in the silo.
