Testimonials 



In compiling this booklet our object has been, not the produc- 

 tion of a literary selection, but a thorough, concise and honest 

 exposition of the monolithic silo and our system of building it. 

 Our aim has been plain straight forward facts, which we take 

 pleasure in endorsing. We know, of course, just what the Polk 

 System is, and what it will do, and we back all our statements 

 concerning it, with all the facts and figures that the reputation 

 and reliability of our company guarantee. Of course we may be 

 prejudiced so we wish to conclude our booklet with the opinions of 

 just a few of our well pleased customers, whose reliability we gladly 

 vouch for. Lack of space precludes the possibility of a long list, 

 so we have chosen a few representative endorsements that sub- 

 stantiate our position.
