Research men have created startlingly new products. Engineers have designed fac tories capable of producing vast amounts of goods. Investors are wdling to risk money needed for expansion. When these ingredients are properly put together they can result in prosperity. Yet prosperity needs a catalyst--another in gredient that will bring about a successful combination of research, production and invested money. This catalyst is work. Work is the power by which goods are produced. It is the man energy to run factories and to make more goods for more people and at less cost. If this catalyst of work energy is ap plied, Americans will have more jobs and more money t han ever before in the history of our nation ... a nation where all may choose tlie work they like and spend their earnings for the things they want. It is a privilege to work in America . . . and work we must. Without work, pros perity is just a passing dream. Men of Du Pont have ably demonstrated their spirit to work for the creation ol a bet ter America. Their energy is dedicated to-- BETTER THINGS FOR BETTER LIVING . . .THROUGH CHEMISTRY (flU PONI) REG.
