1 That the Polk System mono- 

 lithic silo lasts forever. 



2 That "they are not built of 

 pieces and they can not go to 

 pieces/' 



3 That there are no bands or 

 any wires to adjust and re-ad- 

 just. 



4 That they are rat proof. 



5 That they are "insurance 

 agent proof." 



6 That the wind has never yet 

 blown strong enough to blow one 

 down. 



7 That high silos are the prac- 

 ticable silos and easy, high con- 

 struction is the Polk System's "long 

 suit." 



"They are not built of piece*, and they 

 cannot go to piece*. ' '
