a layer of heavy building paper is placed between the 

 silage and the doors when filling the silo. 



Advantages of Twin Silos. Two silos, if built to- 

 gether at one side of the barn, have an advantage also in 

 dispensing with the building of a chute, as shown in the 

 accompanying illustration. Both silos when placed as 

 shown here can be filled with a single setting of the 

 machiner 



Ground Plan of Silos. 



The chute acts as an exit for the foul air from the barn. 

 The door which connects the barn and chute is tight-fit- 

 ting and slides up and down so that it can run to within 

 a foot of the floor; or, if desired, can be closed entirely. 

 Using the chute as an exit for the barn air will help to 

 keep the silage from freezing because of the comparative 

 warmth of this air. Sufficient light is provided in the 

 silos and chute by putting a window horizontally over 

 part of the top of the chute. 



Where two silos are used one can certainly be emptied 

 every year so that silage in no case needs to be kept 

 longer than eighteen to twenty months. Two silos are 

 desirable also for best results in feeding silage during the 

 summer or early fall, as well as during the winter.
