AT DIZZY HEIGHTS...... he spreads a coat of red-lead DAILY he dangles in W mid-air. The steel skeleton of a building that is to be, or a network of bridge cables, is his only foothold. Where he works, breezes be come whistling gales striving to tear him from his precarious perch. Below him move many tiny dots, skeltering about like so many ants, all unaware of one of their kind who works at dizzy heights just to spread a thin redfilm of lead paint. "Why," you ask, "must he do it?" Be cause upon the thoroughness with which he spreads this red film-upon its ability to pro tect the surface it covers-rests, in no small measure, the safety of the structure and the lives of thousands. Protecting the strongest steel The best protector for metal surfaces used by man today is pure red-lead paint, made from lead. Such a red-lead is Dutch Boy red-lead, preferred by the United States Navy, emi nent engineers, contractors, and builders.

When such a film is prop erly maintained, it gives lasting protection.
