Providing the Sinews of War Mother Earth has been kind to our country. With lavish hand she has bestowed upon us mineral wealth. Our industrial strength springs from this gift of hers and our military strength is dependent on it. Our ships, our railroads, our great steel mills and iron foundries, our mammoth buildings-all are born in our mines. It is to our original sources of iron, copper, zinc, lead, coal and other minerals that we owe our eminent position among the nations. The Hercules Powder Company creates the forces that tear these minerals from the imprisoning rock and earth. By far the major portion of our output of explosives has for years been used by the miners of the country. And the miners of the country are providing a great part of the sinews of war which will ultimately bring us victory. RERCULES POWDER CO.
