in half-inch lengths. Corn ensilage must usually be 

 trampled upon and evened as the layers are put in, in 

 order to distribute the parts evenly. 



Note. A flexible pipe called a distributor is attached to the end of 

 the blower pipe at the top of the silo. This carries the silage down into 



the silo and as the man 



in the silo shifts it about 

 the silage is distributed 

 evenly. As the silo is 

 filled, lengths of the dis- 

 tributor pipe are removed. 



Special care must 

 be taken to trample 

 well near the walls 

 as their surface of- 

 fers some resistance 

 to the settling mass. 

 In the more mod- 

 ern deep silos, less 

 trampling is neces- 

 sary, but the sur- 

 face must be kept 

 even. 



If delay occurs 

 during the rilling 

 of the silo, care must 

 be taken to leave 



an opening at the

level of the silage 



for proper ventilation, otherwise the carbon dioxide 

 which forms above the mass will suffocate one descend- 

 ing into it.
