 These structures are 16 by 45 feet, the upper four feet of the one 

 on the right being given to a concrete water tank. This shows one

 would otherwise be a great cost given to you absolutely free of 

 cost when you pay for your silo. WE HONESTLY CONSIDER THIS 



THE BEST OFFER WE ARE MAKING TO THE AMERICAN FARMER TO-
