MONSTER SHEARS CLIPPING STEEL SLABS WITH AN EASE AND SMOOTHNESS WHICH 



SUGGESTS PARING CHEESE 



_ The capital employed in the steel industry of the United States is greater than the 

 national Avealth of Switzerland. The Republic of Portugal — land, improvements, industrials, 

 everything — is not worth as much by a billion dollars as x\merica's steel products were in 

 the single year 1914, a year in which a ton of pig iron sold for less than one-third present 

 quotations. 



of finished steel products lead back to the 

 mold. Whether it be a huge girder, a 

 steel rail, a giant shaft, a locomotive drive 

 wheel, a hundred-ton gun, a 14-inch shell, 

 a physician's scalpel, or a pocket-knife, 

 the mold is mother of them all. 



And the nemesis of all these products 

 is rust, for iron and steel alike, when ex- 

 posed to the elements of the air, undergo 

 oxidation, as if yearning to return to that 

 form in which they were taken from the 



earth. Government experts have esti- 

 mated that 23 per cent of all iron and 

 steel is destroyed each year through rust. 

 a truly appalling waste to contemplate. 

 Numerous methods are employed to 

 check this tendency to rust. Surfaces 

 are covered with resins, oils, paints, and 

 metallic compounds. One of the most 

 successful of these protective methods, 

 widely used in the automobile industry, 

 is known as the Parker process, perfected
