STEEL CANOPY GUARDS STONE AGE BUILDING Government engineers have just erected the odd steel umbrella pictured above to shelter from the elements a twelfth-century pueblo watch-tower in Arizona. Archeologists consider the mud-walled structure the most important of its kind. The Stone Age builders bored two holes in the walls, so aligned that beams of the [...]
You have probably seen amusing little animal novelties made by twisting pipe cleaners together, hi most cases they are comical enough, but stiff and grotesque— almost childish. It is therefore a revelation to see, from the illustrations accompanying this article, what lifelike results can be obtained by one who is skillful at this pastime.—The Editor.

Powerful Ray Speeds Radio Program Across Half-Mile of City Buildings RADIO fans witnessed a twentieth-century marvel, the other night, when they listened to a radio program transmitted over a ray of light. High in the tower of the Chrysler Building, in New York City, an orchestra played before a microphone. No land wire linked it to the broadcasting studio half a mile away. Instead, the blue beam of a 50.000-candlepower searchlight sped the music across intervening rooftops.

WITH its deep, mellow notes, the electric organ is fast gaining the musical limelight. As a rule, these instruments are large and costly. Yet, for the price of a new hat, you can build a duplicate of a small organ that was featured in a recent coast-to-coast radio broadcast.
By Robert E. Martin SPELLBOUND at a microscope, Prof. Charles B. Lipman, University of California biologist, recently gazed at what he believed to be the first living creatures from another world ever observed. Tiny germsâ€”some round, some rod-shapedâ€”swarmed beneath the lens. Despite their minute size, they were as fascinating to a scientist as any hypothetical man from Mars. If Prof. Lipman has correctly explained the germs' origin, they came to earth carried by a flaming meteorite from the voids beyond our planet! Here, after centuries of speculation, seems the first credible indication that life exists outside the earth. To test the possibility that living things might exist in other worlds, Prof. Lipman acquired a number of stone meteorites that had fallen on the earth. He proposed to grind these to powder and drop the powder in suitable culture media to see whether germs would grow. If so, evidence would be strong that the germs had survived the cold of the journey through space, the heat of the flaming meteor when it struck the earth's atmosphere, and the years the meteoric stone had rested on the ground or in a museum case. Of course it would be necessary to take extraordinary precautions to make sure the meteorite was uncontami-nated by bacteria from the earth.
Steel Shield for Policemen is Bullet-Proof Bullets crashed and ricocheted recently in an exciting test of a new shield for policemen at Chicago, Ill.

Recent Operations of a Sensational Nature Are Described for You in This Article, Fifth in Our Series Dealing with Modern Surgery By Frederic Damrau, M. D. LIFE-SAVING by surgery, the most dramatic phase of modern medicine, now includes the removal of whole organs from the human body. This is one of the most recent daring advances in the technique of the operating room. Miracles of this kind, performed again and again, have proved you can live without a stomach, with one of your lungs entirely removed, with a kidney gone, and even with part of your brain taken away by the surgeon's knife! At the famous Mayo Clinic at Rochester, Minn., two years ago, a man nearly seventy years old, had his entire stomach removed. Afterwards, he could eat anything he could before and he could digest it better.

THIS remarkable article tells you how the ingenuity and skill of motion picture directors solve the hard emblem of putting on the screen the forms and noises of animals that have been extinct thousands of centuries by Andrew R. Boone FROM the slime of tropical mud flats, the ghost voices of prehistoric monsters have reached the screen. Hisses and grunts of the pterodactyl and brontosaurus; roars from a tyrranosaurus, largest of the dinosaur family; groans and roars of an imaginary giant ape are reproduced by mechanical contrivances. Kong, the ape, crashed through the heavy growth of an unknown forest, uttering fierce growls and beating his breast in rage. As the scene unfolded in silence before a small group of us in a tiny projection room, the studio sound experts discussed ways and means of re-creating his awful voice and the solid thumps of clenched hands against the massive chest.
Fairly ironic ad for a tobacco company… it’s fun to be fooled …it’s more fun to know Here’s a trick used in cigarette advertising.

By Arpad KIRNER French Engineer and Scientific Explorer A SLENDER white thread, a rope of asbestos, rose straight above my head to the edge of the cliff. Below me were boiling lava and billowing fumes. Dangling at the end of the rope. I was being lowered 800 feet into the mouth of an active volcano! A steel helmet protected my head from flying rocks. My suit, my shoes, my gloves, were all made of asbestos. Strapped to my back, were oxygen tanks that enabled me to breathe amid the fumes. I was realizing a scientific adventure which I had planned for years. My friends thought I was crazy when I announced my intention to explore the crater of an active volcano, to descend the depths of its enormous pit, to photograph the infernal vent-hole while it fumed and grumbled, to go where explosions rapidly follow one another and where phenomena, still mysterious, constantly occur.
