WHIRLING BLADES—the best aircraft propellers in the world today—are pulling our warplanes to their smashing victories on all fronts. An article by James L. H. Peck describes the development of propellers from the first simple wooden airscrews to the ingenious mechanisms of today, which are designed to get maximum efficiency from our superb engines and planes.

ARTHUR GRAHAME
IN A little waterfront tavern at Port Richmond, N. Y., few patrons even noticed the stoop-shouldered, 57-year-old porter, busy with mop and pail. Anyone taking the trouble to inquire would have learned that he operated his pleasant brick home in near-by Tompkinsville as a boarding house for service men, and that he was one of the most zealous air-raid wardens to be found in the vicinity.

These and many other features of battleship design, as exemplified by the 35,000-tonners of our modern North Carolina class, are illustrated below by S. W. Clatworthy, noted British technician, in drawings from the “London Sphere."

Can We Fly at 50,000 Feet ?
Dragging his planes to ever higher levels, man encounters deadly enemies in cold and low air pressure. . . . Can science conquer the stratosphere?
WHAT ARE THE ADVANTAGES OF FLIGHT IN THE STRATOSPHERE?
...AND WHAT ARE ITS PROBLEMS?
ENGINEERS ARE BUSILY SEEKING THE ANSWERS TO PROBLEMS THAT PUT A CEILING ON FLIGHT

WILLIAM S. FRIEDMAN
MODERN military air operation has established certain advantages for high-level flying. The first, of course, is virtual immunity from antiaircraft fire. Another is freedom from interception, because the higher the airplane flies, the greater the time lapse before intercepting aircraft can climb to the level of the high-flying ship.

Why We Can't Lose
Victory FOR THE UNITED NATIONS IS IN THE CARDS. THE TRUMPS WE HOLD ARE MARKED "MILITARY CAPITAL", "FLEXIBILITY", AND "COMMUNICATIONS"
[no value]

FLETCHER PRATT
WE CAN’T lose. For three main reasons we can’t lose: three reasons which can be summed up under the headings of Flexibility, Military Capital, and Communications. Of these, only the third has really begun to produce its effects—but those effects have already given us victories on the enemy’s doorstep in Sicily and the Solomons, and have made possible the battering from the air received by the German and Italian cities.

TO INCREASE the hydroelectric-power output of Niagara Falls—and, incidentally, to preserve their natural beauty—a stone weir has been built across the Canadian half of the Niagara River bed. War industries on both sides of the border profit from an international agreement, of which this project is part, to increase the amount of water used for power from 56,000 to 82,500 cubic feet per second.

IT REQUIRES no great imagination to reconstruct the scene at Hitler's headquarters on the night that the British Eighth Army blew the lid off at El Alamein. Rommel had just sent a wire to his boss, saying he had that mouthy little squirt, Montgomery, backed up against Alexandria and was about to blast him with those invincible German 88-millimeter tank guns and then sweep all North Africa bare of British resistance with a thousand tanks flying the black swastika.

AGGRESSIVE defense against bodily attack, and skillful offensive tactics against an unarmed opponent, are easy if you learn the basic principles taught American Ranger and Raider battalions. The whole secret lies in disabling the enemy by locating the main nerve centers in his body and bringing pressure against them to cause extreme pain or temporary paralysis.

IN INDIA, today, our soldiers may see little metal plates, bearing numbers arranged in squares, worn by the natives as amulets. These are “magic” squares, first constructed by ancient Hindu and Chinese mathematicians, and believed to be endued with magical powers because of certain remarkable but purely mathematical properties which they possessed.

JEAN ACKERMANN
WINGS, propellers, engines— practically every inch of our warplanes needs a filing job before it is ready for action. Tiny Swiss Pattern files are used to form dies and to clean out slots; a curved-tooth file roughs down a wing surface; a rasp trims the edge of a propeller—and 2,000 other files perform special jobs necessary to put a plane into the air.

The device consists of a flexible hose attached to a float which rises to the surface when the conduit is set free. In addition to providing an air line, the apparatus might be used as a means of indicating the location of a submarine trapped on the ocean floor, or even afford a means of communication with the crew from rescue vessels on the surface.

THE drawing and photographs on this page, which recently appeared in “Signal,” Herr Goebbels’ English-language propaganda magazine, are that master mind’s idea of an effective counterattack in the war of nerves. With characteristic heavy-handed German subtlety, they were intended to impress Allied readers with the impregnability of Europe’s west-coast defenses, and to suggest, of course, that invasion could result only in something approaching national suicide.

POTTERY making is one of the oldest American handicrafts.

A HIGH-SPEED, air-propeller-driven boat that literally rolls over the waves has been proposed by Pietro C. Lombardini, of England. In starting, the boat moves through the water on its hull, but once it attains 50 knots, a series of free-turning rollers, lowered into the water in place of the hull, reduces the boat’s resistance and enables it to increase its speed greatly.

MORE than 100 horsepower of electrical energy—1 amp. at 100,000 volts—flows into the giant industrial X-ray tube that spots defects in heavy steel castings. Possibly in the same plant there is an “electric eye,” or phototube, that gauges the color of incandescent metal in a Bessemer converter and signals when the blast must be shut off.

CERAMIC BATTERY CASES are replacing those formerly made of rubber for industrial, public-utility, emergency-transmitter, and telephone service. Four clays are blended to produce this vitrified ceramic, which is acidproof, is easy to keep clean, and can be heated to 212 deg. F. and plunged into ice water without contraction.

MICHELE DE SANTIS
CONVENIENCE and an attractive appearance are features of this outdoor rack for garden tools and hose. A rack of this type will save the home gardener many extra steps during the months when tools are most frequently needed. It is not usually desirable to put the rack to year-round use, however, nor to install it where theft of the tools is a possibility.

SCRAPS of wood from larger projects will do for building this sturdy tackle box. Use ⅞" stock for the ends, ⅜" plywood for the sides, top, and bottom, and ¼" stock for partitions. A lining of ⅛" composition board extending up ¼" from the bottom section on the sides and ends creates a watertight joint when the lid is closed.
