THE POLK SYSTEM 



modern farmer has found it his greatest single agency in the con- 

 struction of a farm on the business basis. He has circumvented 

 deteoriation- he has no up keep his profits go into the bank: 

 because, simply because he has used concrete in the building. 

 Concrete is vauable on the farm because it can be put to an almost 

 endless number of uses. From the basement to the water-tank, 

 from the barn to the fence-post, from the silo to the cistern, in 

 the corn-crib and the trough, on the floor and the sidewalk, we 

 find concrete. No one WHO KNOWS builds with anything but 

 concrete, it means sanitary conditions, puts the kibosh on the 

 rats and mice, turns water at the roof and in the basement, laughs 



at fire and makes the insurance 

 man drive on to the next place 

 in hopes of finding an easy vic- 

 tim. Build with concrete and 

 don't mind the weather even if 

 the wind ''do blow." What do 

 you care? Build with concrete 

 and build right and nothing 

 but a double-geared, back ac- 

 tion, hammerless, six-cylinder, 

 earthquake could ever ruffle 

 your peace of mind. 



BUILD RIGHT! We 

 know how to do that today. A 

 few years ago some mistakes 

 were made by workers in con- 

 crete, because they were care- 

 less about proportions and mix- 

 tures. These mistakes have 

 been given wide publicity as

proof that concrete is not a 

 construction, and consequently 

 some of the unwise fear the concrete is tricky. Today the fail- 

 ures by inexperienced and expert are not one in a hundred.
