Silent except for a faint chug-chug at the start, a steam-driven motorcycle is in operation in Miami, Fla. It runs smoothly at one mile or fifty per hour, makes fifty miles per gallon of gasoline, kerosene or distillate and has no gears.
Electric range with control which keeps food at "simmer" heat. The stove has two lighted ovens and lighted platform lights. Right, steel wool holder made of rubber.
Table which can't tip over and, at left, enameled metal window shelf for potted plants which can be attached by tightening one wing nut.
Combination of a high-speed tank and a fast plane is the new war machine being developed by Walter J. Christie. In military service, the tank would be attached to the fuselage of the plane to be transported to any point desired. Upon landing, the tank would be detached, free to advance on enemy positions.
Looking as though it might be as much at home in the air as on the ground, a motor truck propelled by air sucked through a wind tunnel is testing principles that may revolutionize the building of dirigibles. Air is drawn into its concave, funnel-shaped front by a small propeller and is forced out at the rear with tremendous velocity, sending the car rocketing across the earth.
ALTHOUGH it covered only a few hundred feet, the recent flight of the "Gloria," America's first air mail rocket, at Greenwood lake in New Jersey, may in time be considered as significant as that first historic flight of the Wright brothers at Kitty Hawk, which covered an even shorter distance.
because Ingram's does these three things When you start using Ingram's, you stop getting hot shaves. For three special ingredients in this rich-lather cream do these three things to make all shaves quick, clean and stingless—
1st, they wilt whiskers softer at the skin-line, where your razor works. 2nd, smooth your skin so the blade can't skip and scuff. 3rd, cool your face while you shave, keep it cool when you've finished.
THE STRANGE effects of extreme heat and cold on common substances is arousing interest in what may become a field of sensational discovery.
For years man has sought to extend his command of temperature and pressure, but until quite recently he was restricted to the ordinary temperatures found in nature. Today there are about ten special low-temperature laboratories scattered about the world. After twenty years, the low-temperature laboratory at Leyden, Holland, has succeeded in coming within five-thousandths of a degree of absolute zero, which is —273 degrees Centigrade. This establishes a record for cold that is likely to stand for some time.

TRAVEL, with its many broadening influences, should be a major course, required in every man's education.
Travel is expensive only if you choose to make it expensive. It can be as cheap as staying at home. Our roads are good, our automobiles are relatively cheap, the cost of fuel is low, and food and lodging, if you look for them in the right places, are not high.
I nursed a pet theory for a long time before I was able to try it out. I believed it was possible to spend thirty days seeing America from coast to coast, and from Canada to Mexico, at a total cost of $100 per person in actual travel expenses. And by seeing America I don't mean racing from dawn to dark along the highways until you're so tired driving you can't sleep and so sleepy you can't drive.
WHAT has the power age done for America? Experts now give the United States credit for performing half the useful work of the world. This means that Americans, with the help of science and invention, accomplish as much work as 1,875,-000,000 people in other parts of the world, or that one-sixteenth of the world's population now performs as much work as the other fifteen-sixteenths. This is not a chance guess, but is based on a recent world survey by Prof. T. T. Read, of Columbia University.
Streamline Tricycle Serves Ice Cream in the Streets Ice cream is dispensed in the streets of London from tricycles equipped with streamline bodies which extend over the tops and sides of the vehicles. The top of the body forms a “counter” to hold the dispensing equipment.
Electric Horse with Five Gaits Used for Indoor Exercise Some of the benefits of horseback riding as a form of exercise can be obtained indoors with the aid of an electro-mechanical horse which not only provides fun for the children but sport for grown-ups as well. At a touch on the reins, the horse can [...]

FROM bronze to iron, from iron to steel, and now a new era—that of steel and its alloys—such is the story of human progress.
Before the Napoleonic wars, this was a world of hard labor. Then came steam to lighten toil, and to lift loads off men's backs.
Iron supplanted bronze. Steel displaced iron because it was stronger. Certain kinds of alloys today surpass ordinary steel in physical properties— strength, toughness, hardness, resistance to oxidation, the action of chemicals, stability at high temperatures, electrical characteristics and luster.
Pocket Vapor Bulb Operates Like Flashlight As handy as a fountain pen, an electric vaporizer that works like a flashlight has been designed as a “pocket relief” for colds. In the head of the tiny metal case is a special bulb with two openings. A few drops of a nasal inhalant are inserted from the [...]
Riders on Rear End of Truck Kept Off with Barbed Wire The owner of a large truck fleet who had experienced several accidents resulting from boys riding on the rear ends of the trucks, used the method shown to discourage this practice. Boards were wrapped with barbed wire and fastened to the tailboards of the [...]
Off to Prison Convicts Ride in Rumble Seat “Jail” Cage Oklahoma has a jail on wheels to take its convicts to prison. Instead of a rumble seat, the prison transfer car has a barred steel cage mounted behind the coupe body. Alex Watson, in charge of the transfer of prisoners, can watch his wards in [...]
Light and compact enough to be drawn behind a motor car like a trailer, a movable type of house can be expanded to form three rooms at its destination. On the road it is supported on two wheels with drop axle and is sixteen feet long and six and one-half feet wide.
