TRAPPING ENEMY SPIES
by THOMAS M. JOHNSON Author of "Our Secret War" and "Without Censor" "A SPY simply must communicate with his master," the foremost American hunter of spies told me. Then he added, fervently; "Thank God!" For the very act of sending his precious stolen information to the country he serves, places the war time spy in deadly danger. The "spy wireless" by which he sends it, is his strength only if it be safely hidden; once discovered, it is his weakness, betraying him to death at dawn before a firing squad. Through that fatal weakness, American spy hunters recently have detected an astounding number of spies for foreign countries, here among us, stealing our defense secrets.

RAISING the German Fleet
By JOSEPH W. GRIGG, Jr. TOILING in the icy depths of Scapa Flow, the broad landlocked harbor in the Orkney Isles, north of Scotland, British engineers and divers today are enacting what probably will be hailed some day as the greatest salvaging epic in the history of the sea. Though the world at large hears but little of their feats, they are dragging to the surface one by one of the giants of Germany's once proud High Seas Fleet, now battered rusted hulks, which have lain for 17 years fathoms-deep beneath the swirling waters of Scapa. The iron from some of those very ships is being used today by the modern Germany of Adolf Hitler in the great European armaments race.

"Hit-And-Run" Victim Devises Camera Trap For Motorist
AN AUTO-FLASH device designed to snap photos of autos that run past red lights, into safety zones, and past stop streets, has been invented by William Running, a Detroit, Mich., electrician. A personal experience as a "hit-and-run" victim caused him to design the device. For safety zones, the machine consists of a lighted sign set in the pavement which depresses when an auto passes over it. This actuates a camera set up on the curb so that it snaps a photo of the rear license plates of the offending auto.
