LOOKING like whirling surfboards, strange new rotors will furnish the power on a boat now nearing completion at Chicago. Laurence J. Lesh, pioneer aeronautical engineer, is designer of the craft. Unlike the Flettner rotor ship, which attracted wide attention a few years ago, his boat will depend entirely upon the wind for propulsion. No engines will be required to keep the rotors turning, as was the case with the high "chimneys" of the German craft. Once the pointed, vertical wings of the Lesh boat begin spinning, they keep on until the wind dies down or the brakes are applied. The lightest of breezes, tests have shown, will start them whirling and move the ship.
CALIFORNIA FISHERMEN WEAR DIVING HELMET Fishing in a diving suit is the latest sport innovation at Catalina Island, Calif.

His trailing air hose is attached to [...]
Successful Flights with Long-Sought Craft Crown Many Similar Attempts by Early Aviation Engineers By H.J. FitzGerald OVER the Oakland, Calif., Airport, a few days ago, a silent plane slanted across the sky trailing a thin ribbon of white vapor. Spectators heard the pilot shout a greeting from the air. They saw him flash past, skimming the ground at a hundred miles an hour. They watched him bank into a turn, slide to a landing, and, with the propeller spinning backward, roll to a stop in less than a hundred feet. They had seen, for the first time in history, a man fly on wings powered by steam! Two brothers, George and William Besler, the former a geologist thirty-one years old, and the latter a mechanical engineer, two years younger, have achieved the dream of Maxim, Langley, and other pioneers of flight. Through their work, the steam-driven airplane, long talked about, long planned, has become a reality.
It’s hard to imagine a hospital without a P.A. system.

This is part of a whole series of Camel ads all with the theme: “It’s fun to be fooled – It’s more fun to know”. Which I find pretty funny considering that Camel spent the next 80 years or so lying through their teeth.
By Robert E. Martin ITS engine throttled down, a black touring car swung noiselessly into the driveway of an unoccupied house on Long Island, thirty miles from New York City. Two men hastily entered the building carrying bundles and cans. It was three o'clock in the morning. The owner was hundreds of miles away on his vacation. Twenty minutes later, neighbors tumbled from their beds at the sound of a terrific explosion. Through its shattered windows, they saw the vacant house lighted up by a plume of yellow flame flaring half across the basement from a broken gas pipe. Two dark figures were picking themselves up from the front yard outside one of the windows. They scrambled into the touring car, backed swiftly into the street, and raced away.

How Blasts of Grain Dust or of Gasoline Vapor Are Caused in Your Laboratoryâ€”Tests With Which to Prove a Burning Candle Is a Gas Plant By RAYMOND B. WAILES HARMLESS, miniature explosions make experimenting with combustibles a thrilling, yet safe, amusement for the amateur chemist. With inexpensive homemade apparatus, he can duplicate the explosions in a gasoline motor and amuse his friends by burning air. When we say a substance burns, we imply that it combines with oxygen to produce heat and sometimes light. Hydrogen and carbon, as well as many other substances containing these two elements, display this property. A candle, for instance, is made of paraffin, a combination of carbon and hydrogen. When the wick is lighted, the paraffin melts and produces hydro-carbon gases, which decompose to form other inflammable gases and carbon.
BIG CROSSBOW HURLS MAN FIFTY FEET Somersaulting fifty feet through the air from a giant crossbow, a California daredevil recently introduced a new circus thrill.

REVIEWS WORLD'S GREATEST CENTURY By Edwin Teale AFTER a forty-year journey through space, a reddish ray of starlight has just struck a photo-electric cell and flashed on the lights of a $25,000,000 extravaganza of science, the Century of Progress Exposition at Chicago. Islands to accommodate the show, were built in the waters of Lake Michigan. Grass and trees and towering buildings cover them and hundreds of thousands of glowing, gas-filled tubes illuminate the great exposition. Covering 338 acres, the thousands of exhibits compress into the scope of an exposition the drama and wonder of history's most amazing century of scientific advance. Under your eyes, crude rubber changes into auto tires; casein, extracted from milk, becomes a fountain pen; piles of parts turn into automobiles that speed away under their own power.
