262 SOILING CROPS AND THE SILO. 



such feeding may injure the animals and even 

 seriously. The difference in the effects produced on 

 digestion by feeding the same kind of food in the 

 green and dried forms respectively, is well brought 

 out in the feeding of grass when in the most com- 

 plete state of succulence and in feeding the same 

 as hay. 



Economy in Storage Space. The silo is eco- 

 nomical of space in storing food. In other words 

 it requires a much less area to store food in 

 the green form than to store it when dried. This 

 means therefore that a given amount of green food 

 can usually be stored in a silo at a less cost for the 

 storage accommodation than would be entailed in 

 providing storage room for the same in the dried 

 form. 



This advantage is however to some extent offset 

 by other considerations. First, it is necessary to 

 make some provision by way of storage for other 

 food. When the expense of providing storage for 

 both green and dry food cannot be borne by the 

 farmer, he can better do without the storage for the 

 green food. Second, the silo in some of its forms 

 wears out more quickly than structures made to 

 receive dry food. The saving in storage space 

 effected by the silo is most apparent when large 

 quantities of food are to be handled. 



Economy in Labor When Feeding. The silo is 

 economical in labor when feeding the food. It can 

 usually be located so that the food is nearer to the 

 place of feeding than it would be possible to store 

 equal quantities of dry food in the cured form. It 

 is easily handled because of its lack of bulkiness and
