CANVAS is now being considered by architects as an attractive and economical building material for the small homes of the future. Canvas can now be treated with preservative paints to make it waterproof and fireproof. A summer home which can be built anywhere for less than $1000 uses canvas almost exclusively as a surfacing material.
IT IS gratifying to the Editor of this Department to note the rapidly increasing interest in inventions on the part of the readers of Modern Mechanix and Inventions.

Deep in the earth, men bore through mountains and under river beds to build our tunnels. Deadly peril constantly stalks them. Here is the thrilling story of their work— one of America's most hazardous occupations. by Alfred Albelli GROPING along like so many human moles, the Montague street tunnel crew pushed its way beneath the East river, separating Brooklyn and New York City. One moment the big cutting shield was boring steadily forward—the next, disaster struck with the fury of a tornado. The shield had cut through to the riverbed above!
by MAXWELL REID GRANT Poison death lurks in common table fruits and vegetables. Here is the story of how science battles to safeguard our foodstuffs. ARMED with beakers and test tubes, scientists are waging a grim struggle against one of America's most deadly enemies—the fatal poisons that lurk in common household foods.

by CLARENCE EBEY TRAPPED in a field of treacherous pack-ice twenty miles off the Alaskan coast, the freighter Anyox, two gaping holes in her ice-crushed bow, was slowly settling to her doom. Twenty-eight hours earlier the ship's imperative distress call had crackled through the arctic ether as desperate men had leaped to lash tarpaulins over the battered bow. The initial rush of the hungry waters had been checked; but not before the hold had partially filled and one of the engine fires had been extinguished. Doggedly the men fought the inevitable, but it was a losing battle. Slowly, inexorably, the clutching waters inched their way upward along the freighter's hull, pulling her ever lower into the trough of the sea. It was the end. The Anyox was doomed.
New burners for gas stoves have openings in side of mountings. Boil-overs run past fuel openings and will not clog flame. A bridge table beverage shelf keeps glasses and smoking trays from cluttering up the table. The metal shelf holds two glasses and a cigaret tray and is attached to the table leg.

by WILLIAM JENNINGS COOLING slowly in a brick igloo in Corning, N. Y., is a lake of 34 tons of molten glass, representing the greatest scientific project ever attempted by man. It took six years to reach this stage of the great task and it will be more than four more years before its success is known. From far and wide scientists came to see the formation of this huge lake of glassâ€” the pouring of the 200-inch telescope mirror that is expected to reach out into the unknown depths of the universe. The work has hardly begun with the pouring of the mirror. Countless problems still face the scientists who have undertaken the task.
Triumphing over nature's grim and forbidding barriers, engineers are building a super highway linking Alaska and the Argentine. Here is the story of the greatest road project in history. by PETRIE MONDELL HACKING their way through tangled jungles, braving the quicksands of treacherous streams, hauling equipment by sheer man power up towering cliffs and over once impassable mountain ranges, dauntless engineers are bending every effort to bring the mightiest highway in all history to completion. The finished project will link two continentsâ€”a Pan-American roadway extending from northern Alaska to the southern Argentine.
FIRST cousin to the autogiro, a new circular-wing airplane recently tested in Chicago is so simple in operation that one who has never been off the ground can learn to fly it in thirty minutes, according to the inventor. Instead of the conventional wing structure, the new plane has a huge saucer-like disc trussed above the fuselage. At the rear of the wing are two ailerons which enable the plane to land at low speeds.
Pulsating Wing to Drive Propless Plane LACKING both propeller and tail assembly and driven only by a 10 H.P. motor, an Austrian plane is expected to take the air this summer.

Built to withstand fires, bombs and the raids of super criminals, the nation's newest treasure house is the last word in safety. Here are the reasons why. by JAMES NEVIN MILLER UNCLE SAM'S new gold vault is the greatest and strongest fortress in the world. No fire can harm it. No bomb can damage its mighty walls. The most brilliant cracksmen cannot penetrate its baffling defenses. Built of steel and concrete whose strength is unbelievable, this giant treasure house is equipped with mysterious passageways, secret doors and an automatic alarm system whose scale is the largest ever conceived by the mind of man.
COOLING big cities by means of underground air ducts has long been the dream of inventors and sweltering citizens alike. A plan is now being seriously considered by a Chicago scientist, Dr. Gustav Eglov, of the American Chemical Society. Dr. Eglov believes that huge refrigeration plants built at intervals of a mile and a half along city streets would rid the canyons between sky scrapers of humid hot air.

ANOTHER use has been found for that mysterious power known as electricity, and this time it will find favor with all mothers. The photo-electric cell, popularly known as the "eye which never sleeps," has been mounted on baby's crib. It watches throughout the night, ringing an alarm the instant anyone tries to reach into the crib.
ALMOST human is "SHE," work of Courtenay Pollock, well known sculptor of London. With the aid of a small electric motor, "SHE" is smiling, coy, demure, or scornful as her master wills. Rolling her eyes about in an enchanting manner, she even displays a lovely set of dimples. This "living" model is on display in one of the leading department stores of London. A cordon of police are required to keep the crowd moving and traffic clear in the streets.
Air Liners Have Berth Facilities GIANT air cruisers, equipped with comfortable sleeping quarters, will soon take flight, to mark another forward step in aviation. Each plane will have six compartments which may be converted into upper and lower berths. These berths are longer than those in standard railroad sleeping cars and are furnished with reading [...]
AVIATION'S rapid strides are revolutionizing all other modes of transportation. Railroads are meeting the demand for greater speed with streamlined trains. Automobiles are following the most modern trends in streamlining. On the seas, however, even a streamlined ship will not be able to meet the competition of regular airplane schedules touching airports anchored in the ocean. Resistance from wind is great, but the sea itself slows down an ocean liner much more.
Radio Buyers Dictate New Designs DETERMINED to eliminate all guesswork, radio manufacturers recently conducted an intensive survey to determine exactly which cabinet designs and mechanical features most appealed to prospective radio buyers.
