 fire. 



With a single stave silo, like our first large 

 one, the hoops should be watched very closely 

 for a few days after the silo is filled. If the 

 strain becomes quite intense, the nuts should 

 be slightly loosened. If, during the summer, 

 when the silo is empty and the staves thor- 

 oughly dry, the hoops are tightened so that 

 the staves are drawn closely together when 

 the silo is filled, and the w r ood absorbs mois-

 eased somewhat to allow for the expansion. 



Freezing of silage is sometimes a source of 

 trouble. The single silo can be enclosed by a 

 wide jacket of rough boards nailed to four 

 uprights, leaving the section of the silo where 

 the doors are easy of access. The space be- 

 tween the silo and outside jacket is filled with 

 straw in the fall. This may be taken out and 

 used for bedding in the spring, thus allowing 

 the staves to be thoroughly dried out during
