frosts as any other material. Of course this is a mat- 

 ter which varies greatly with the latitude, so that 

 while in some localities frost does not have to be con- 

 sidered, there are other places where it is almost im- 

 possible to exclude frost entirely. In these latter locali- 

 ties it has been found that a double concrete wall with 

 an air space intervening will reduce the destruction 

 of silage by frost to a minimum. In fact, it is safe to 

 say that there is no latitude where corn can be raised 

 where a silo of this kind, if properly constructed, and 

 with openings protected, will not keep the silage in 

 practically perfect condition.
