A NEW fire brick, one-third the weight of a standard brick of the same size, and light enough to float on water, is expected to revolutionize the brick industry. Robert F. Martin of Philadelphia is the inventor. Smaller foundations will be possible in brick buildings, since the dead weight of the walls is cut in three. Handling costs will be much less.
Chops Wood With Steel Hands DELICATE but powerful are the steel hands made by Andrew A. Gawley and his blind father.

A MACHINE gun hardly heavier than an air rifle, yet capable of firing 700 shots a minute with almost no recoil and no possibility of overheating, was recently 'announced by its inventor, Clyde Farrell of San Francisco. Special bullets receive only an initial impetus from the firing pin, and generate their own energy in flight, just as do rockets. All remaining energy is released when contact is made with the target.

PHOTOGRAPHS of a man flying through the air by his own power, the dream of scientists for centuries, completely fooled outstanding U. S. newspapers recently. Captions on the photographs, coming from Germany, explained that Pilot Erich Kocher took off with a pair of rotor wings strapped to his chest. Kocher supposedly blew into a box which converted the carbon dioxide of his breath into fuel to operate the rotors. The turning rotors developed a vacuum ahead pulling the man through the air.

MAN'S greatest problem is the weather. It destroys crops; it kills thousands of persons annually; it causes disastrous Hoods, tornadoes and cloudbursts; in the form of a drought it brings starvation, disease and suffering. In three weeks of August, 1896, a "heat wave" caused 2,036 deaths from sunstroke in the United States alone. Two years earlier a hot spell destroyed $50,000,000 worth of crops in the single state of Iowa.
Light Beams Guide Blind Thru Building Without Escort BEAMS of light now guide the sightless through building corridors and up and down stairways. The subject is equipped with a portable photronic cell unit which sounds a buzzer as long as the operator travels along the light beam. The buzzing ceases when the course is changed. […]
A RADICALLY new type of landing gear is now being used on a German low-wing monoplane, permitting the ship to land with equal ease and safety on land or water. Two large rubber balls, resembling nothing more than huge basketballs, spin freely inside cup-shaped boots. On land the balls turn just as wheels do on the ordinary land airplane. On water, however, the balls act as pontoons, skidding over the waves.
DOWN among the coral reefs off the Florida coast lies the world's strangest college laboratory—the under sea classroom of the marine zoology department of the University of Miami.

Big Bee-hive Gets Water From Air AN ODD “drinking water fountain” in Europe acts as a giant artificial spring, condensing the moisture of the air. The thick brick walls keep the inside of the stone structure at a lower temperature than the outside, so that moisture condenses on the thousands of stone slates.
by WILLIAM JENNINGS SAFE from bomb attacksâ€”free from disease and changing temperaturesâ€”living in cities a mile beneath the surface of the earthâ€”such is the dream of science for the man of the future, a not impractical dream which may doom the towers of Manhattan and every other large city to destruction. Despite its towering skyline, the trend of building construction in New York City has been ever downward. Today the island of Manhattan and its surroundings are honeycombed with a vast network of underground facilities. There are more than 130 tunnels and underground areas in the metropolitan district; more than 2800 miles in the subterranean sewage system, and about GOO miles of subway trackage carrying 5,000,000 passengers every day.

Faced with problems that would have staggered a superman. President Roosevelt has come through his first year in better physical shape than when he took office. This story reveals the secret of his amazing vitality and what he does to maintain it. by JAMES NEVIN MILLER EVERY day of his official life President Roosevelt is faced with momentous decisions affecting our national life; yet his greatest problem is not the settling of affairs of state but the safeguarding of his personal health.

by NIKOLA TESLA As told to ALFRED ALBELLI Tesla's World of Tomorrow "We are on the threshold of a gigantic revolution, based on the commercialization of the wireless transmission of power. "Motion pictures will be flashed across limitless spaces . . . "The same energy (wireless transmission of power) will drive airplanes and dirigibles from one central base. "... In rocket-propelled machines . . . it will be practicable to attain speeds of nearly a mile a second (3600 m.p.h.) through the rarefied medium above the stratosphere. ". . . We will be enabled to illuminate the whole sky at night . . . Eventually we will flash power in virtually unlimited amounts to planets." â€”Nikola Tesla.
