The Cavalcade of America sponsored by DuPont,

Maker of Better Things for Better Living,

through chemistry, presents Charles Coburn

in Diamonds at War. Good evening ladies and gentlemen, this is the Cavalcade of America, sponsored by the DuPont Company.

Before we begin our play, here's a news item from the war front which chemistry serves.

Bombers landing on small airfields at the front

often jam on their brake so hard that the tread of their tires buckles

and folds back on itself. That's one reason why the first quantity

shipment of DuPont High Strength nylon yarn will go to tire and rubber

companies this month. Shipments will reach three quarters of a million pounds of yarn before the end of the year.

Nylon can take it.

Tonight we bring you a new radio play, Diamonds at War,

written by Peter Lyon, especially for Cavalcade, and starring Charles Coburn as Mr Eustace Leffingwell, the most

self-assured diamond merchant you'll ever meet.

Maybe you didn't know how vital rough, uncut industrial diamonds are to the war effort.

You may rest assured that our enemies are fully aware of their importance.

So was Mr. Leffingwell in Robert Terrell's best-selling mystery from which our play has been adapted.

Tonight starring Charles Coburn as Mr. Leffingwell, we offer a Nazi spy melodrama which will tell you

a few things you may never have known about diamonds at war. There's the transatlantic clipper settling gently down a LaGuardia airport in New York City.

And here, out of a big plane, come three passengers who last set foot on the ground in Lisbon, Portugal.

Each of them is thinking about Mr Eustace Leffingwell,

but for different reasons.
