Opportunity Eventually concrete will displace all other 

 * material used in silo, water tank, and 

 grain storage construction. Agricultural schools and 

 experiment stations, bankers and insurance companies are 

 backing concrete silo building. They are backing the 

 POLK SYSTEM because it renders a distinct service in 

 silo construction. Farmers have become prejudiced in 

 favor of concrete silos because of their ultimate cheapness 

 and of the lasting service they render. In the field of silo 

 construction lies the greatest opportunity of the American 

 contractor today. 



The contractor who is equipped with a POLK SYSTEM 

 machine and POLK SYSTEM methods can fully guarantee 

 any building he erects. He has the assurance of a big, 

 successful experience behind him. He knows that his 

 work will please far beyond expectation. 



Facilities The new P P LK SYSTEM factory with its 



modern equipment enables us easily and eco- 

 nomically to manufacture machines with every single 

 excellence that years of experience have proved desirable. 

 Not a single expense has been spared that will help to 

 lower the cost of producing POLK SYSTEM machines and 

 equipment and still maintain the high POLK SYSTEM 

 standard of quality. We are putting on the market today 

 the most thoroughly designed 'and the most durable 

 machine that can be made for the erection of monolithic 

 concrete silos. 



Polk System Silos Are Not Built of Pieces
