Where lead is a shield for steel STREAKS of red stand out against the sky. Tiny figures suspended in mid-air cover the cables of the bridge with red-lead. Lead is the shield that protects the steel cables, girders, and beams from rust and prevents the bridge from becoming a death-trap. This is only one of the many ways in which lead constantly serves you and guards your safety. As red lead in paint you see it on metal surfaces everywhere. Red-lead is the standard protection for iron and steel. Nearly twenty million pounds of red-lead are applied to metal every year in this country. Yet this is not enough. Rust still destroys millions of tons of steel. Between 1860 and 1920 the world's output of iron and steel was about 1,860, 000,000 tons. Of this total it was estimated that 660,000,000 tons rusted in use. Wherever iron and steel are, there red-lead is needed to save the surface. Mixed with pure lin seed oil, pure red-lead makes a paint that clings tightly to the sur face and is impervious to air and moisture. New Oak Ave. Ches , Nati John Dutch Boy red-lead is the name of the pure red-lead made and sold by National Lead Company. On every keg is the picture of the Dutch Boy Painter.
