January 2, 1910. 



TO WHOM IT MAY COHCERJJ: 



In the spring of 1909, the Polk, Genung, Polk Co. of 

 Port Branch, Indiana, built for me a reinforced concrete silo, 

 1 ft. by 40 ft. 



The structure seems to be perfect in every respect, and 

 the men who built it, so far as I can Judge from my dealings with 

 them, are courteous, competent, reliable business men. They know 

 their business and promptly do as they agree. 



They are not built of piece*, and they 

 cannot go to piece*.
