THE POLK SYSTEM 39 



FACTS NOT FANCIES 



wood silo is a good thing; so 

 is a board walk while it lasts. 

 ^|The practical silo is the high silo; 

 better ensilage, more capacity, 

 cheaper per ton capacity. 

 <IThe Polk System concrete silo 

 can be built as easily high as low. 

 We are bulding sixty feet high, and 

 predict even higher silo building. 

 tJThe Polk System monolithic silo 

 lasts so much longer that it is 

 cheaper than a wood silo would be 

 as a gift.
