Lead is used by man in almost councless ways. But its most general use is in lead paints. Red-lead and white-lead are knowr and used the world over. Red..lead helps man win the greatest war of all time THIS war is between man and Nature. What man builds, the forces of ature try to destroy. ature is everlastingly striv- ing to return all materials to their original and most stable form. So it has been since the beginning of time. Man uses in his structures, among other materials, the strongest metal he has-steel. Opposed to it is one of Nature's strongest elements-moisture-Iaden air. The air at- tacks this metal which man has won from ature and tries, by what is known as rust- ing, to draw it back to its original state. If the metal is left to face the attack alone, it soon weakens. It crumbles-is destroyed. But few steel structures are permitted to rust rapidly away. Man thwarts Nature by protecting his steel with an armor of lead paint. With pure red-lead such as Dutch Boy red-lead he makes a paint covering through which air and moisture do not pene- trate. The life of steel is prolonged indefinite- ly with this armor of Daint derived from the metal lead. Dutch Boy red-lead has stood all tests for durability. It makes a hard, tenacious film that gives full and economical protection to the metal surfaces it covers. It comes in the natural red-lead color and can be shaded to browns, greens, and black. We shall be pleased to send you "The H andy Book of Painting," which has a spe- cial section devoted to the protection of metal surfaces.
