If we have not already a live agent in your county this is the opportunity for you to make money in the 



CONCRETE INDUSTRY 



Concrete Culverts are "the thing" for Economy and 



Durability. 



In every county from 50 to 200 culverts are re- 

 quired every year. This makes a good business and 

 the taxpayers are more than pleased wherever the 

 Miracle Culvert Forms have been used. 



Culverts are usually built in the following sizes: 

 12, 18, 24, 36 and 48 inches in diameter. 



The price of the Miracle Culvert Forms are reas- 

 onable. They fray for themselves in a single season.
