eight to 136 cows for six months, feeding them an average of 40 

 pounds a day, and the dimensions of circular silos as well as the 

 area of land required to furnish the different amounts of feed 

 given, computed at 15 tons per acre. The amount of silage given 

 in the table refers to the number of tons in the silo after all 

 shrinkage has occurred; as the condition of the corn as placed 

 in the silo differs considerably, these, figures may vary in different 

 years or with different crops of corn, and should not be inter- 

 preted to strictly; the manner of filling the silo will also deter- 

 mme how much corn the silo will hold; if the silo is filled with 

 well-matured corn, and after this has settled for a couple of days, 

 filled up again, it will hold at least 10 per cent, more silage than 

 when It IS filled rapidly and not refilled after settling. To the 

 person about to fill a silo for the first time, it is suggested that
