Introduction 



THE average American farmer is not one-half as rich as he 

 ought to be. There are too many leaks in the business. The 

 one greatest loss to-day is in the handling of the corn crop by the 

 stockman and dairyman. The progressive man who is feeding 

 silage is getting 100 per cent, of the nutriment out of his corn, 

 while the other fellow is getting only about 60 to 65 per cent, 

 and is losing the remaining 40 per cent. 



We are sending this catalogue to you because this is so. We 

 want to give you straight facts in a straightforward manner. We 

 want to show you that you absolutely cannot afford to be without 

 a good silo. The unprecedented rise in land values means that a 

 corresponding return must be got or failure and bankruptcy will 

 follow. The scientific management of the big progressive stock- 

 man means that his competitors will have to stop every leak or 

 else get out of the business. The economy of the silo means that 

 you must own one. 



We wish to show you that the best silo you can buy is the only 

 one you can really afford to buy, that you are losing money 

 when you build a silo that won't last you forever. We want you 

 to read the following pages of facts, undisputable and to judge 

 the proposition fairly. Then if you build anything but an im- 

 perishable monolithic concrete silo we shall be surprised at you. 

 But you won't surprise us you can't afford to. 



We have never had a single failure or a single complaint. Our 

 efficiency is 100 per cent. Every silo that has ever been erected 

 by the Polk system has given absolute satisfaction. Yes, there 

 is a reason. Our machine and our methods don't allow any 

 builder to go wrong. 



We hope that you will closely examine the following pages so 

 that we may convince you that our assertions are true.
