It is the design of the French engineer, M. Freyssinet, intended for the 1937 Paris Exhibition.

A most remarkable battle between a shark and an octopus has been photographed by a daring cameraman for the film, "Samarang"—(Out of the Deep). With his camera and equipment inside a diving bell, open at the bottom, the internal air pressure being sufficient to keep the water out at shallow depths, he placed a piece of meat in the water to attract the shark, the octopus already being in the vicinity. The battle which ensued between shark and octopus lasted twenty minutes, but it was quite one-sided.

Amazing secret battles of spies and cipher experts, involving the use of codes and cryptograms on which hung the lives of millions of men in the trenches, played a vital part in determining the course of the World War. Kept secret for years in confidential archives, some of the startling exploits of American cryptographers are brought to light here.
"The enemy has our secret code!"
The dread tidings were whispered through the corridors of Washington; War Department, State Department, even the White House. They brought a cold chill of fear. Could it be that at the climax of the greatest fighting effort in our history, the Germans were reading our leaders' most confidential messages, knew their inmost thoughts and plans? We must stop that, at once.

1. A Fortune in Earrings
MANY millions of sets of cheap earrings are sold in the chain stores every year. Mechanically these things belong to the middle ages. They are held in place actually by two small set screws that not only irritate but also become loose and permit the earrings to drop off. If you do not believe me ask your wife or your girl friend.

Millions of horsepower of high-frequency electric energy, running "wild" in the air, may be the cause of mysterious disasters to aircraft, such as the loss of the Akron, the dirigible R-101, Knute Rockne's airplane, and scores of others. How these amazing currents affect not only airplanes but your body, your home, and any objects that fail in tune with them, is explained in this unusual article on the unseen menace from the sky.
by BURTON MANFRED
THE radio experts of the United States Navy have recently completed a series of astounding experiments, experiments that prove far beyond the shadow of human error that there is a new menace in the sky. Hour after hour, day after day countless thousands of horsepower of high-frequency electric energy is being pumped into the air by great radio stations and other high-frequency machinery which has become a part of our civilization.
Only an infinitesimal speck of this prodigious output of energy is consumed by the radio receivers of the world. What happens to the rest? Does it become a wild and roving source of death and destruction or does it rush into the frigid voids of space never to return to the earth?
SEASICKNESS, that real terror of the sea, which often makes ocean travel an ordeal, is reduced 30 per cent by the development of a new type steamship bunk, inventors claim.
