Steel is the Foundation of Industry-save it AMERICAN INDUSTRY-partic ularly that part of American in dustry indispensable to the war-must have steel in large quantities. It is the basic material-the foundation upon which rests nine out of ten of our great manufacturing institutions. If the supply of all other metals had to be cut off forever-if we could hand down only one metal as a birthright to future generations-there could be but a single answer-steel. And yet government figures show that right now approximately 23% of all steel rusts away annually-a needless and un forgivable waste. Steel Need Not Rust! Leading manufacturers-concerns in practically every line of metal-working activity-have proved that steel does not need to rust-that rust can easily be prevented by use of the Parker Process. If you buy your equipment new today from the leaders in their respective fields, the lock in your front door, the typewriters in your office, the ex posed metal parts in your automobile, and the steel range in your kitchen will soon convince you with their mute testimony that rust is no longer necessary-that the Parker Process does prevent rust. A Book On Rust Proofing for Industrial Executives Manufacturers and industrial executives who are concerned with the rust-proofing problem will find much of interest in the recently published Parker Process book. This book explains in detail how the Parker Process does its work-who the large manufacturers are that use the Parker Process and how easily the Parker Process can be ap plied to your own production without in any way interfering with your present manufactur ing plans.
