by DR. SERGIUS P. GRACE

Assistant to Vice President, Bell Telephone Laboratories As told to J.

The amazing inventions which make such feats possible are described in this article.

IN A recent lecture on the new marvels being developed in the Bell Laboratories I placed my finger against the ear of one of the members of the audience, and he “heard” music and speech, though not a sound was audible on the stage.

Handy Lighter Built in Cane
ONE of the novel and striking features of the recent British industries exhibition was a walking stick equipped with a gasoline lighter for the convenience of smokers. The lighter is built into the handle of the cane, as photo below shows, and is brought into action by pressure on a small button. Such a device proves a great boon, for it saves considerable fussing around for a lighter or a match. The device is filled with gas from a small opening beneath the cover.

Calling All Inventors

Got a new gadget? Rochester’s industries want to see it. They may even make it and market it for you.

By Alfred Eris

THERE’S a man in Rochester, N. Y., whose job it is to help you make a million dollars! His name is Harold S. Rand and he’s the Deputy Commissioner of Commerce for that city.

What’s the catch? Naturally, there’s a reason for it—but it’s certainly not a hidden reason. It’s simply part of a scheme to keep Rochester’s industries going at capacity.

PEOPLE DON’T DIE -THEY COMMIT SUICIDE

BY BERNARR MACFADDEN

NATURAL deaths are rare. It looks as though John D. Rockefeller, Sr., will have a chance to die as nature intended. The last twenty-five or thirty years he has adhered rigidly to what we might call the laws of life. He has prolonged his life to the end that nature intended for all of us.

We have heard of the saying, “Digging your grave with your teeth,” which, in a way, refers to overeating.

The THREE DECK CITY is COMING

by UTHAI VINCENT WILCOX

THE three-deck street is coming. Our sons and daughters living in the great cities of tomorrow will have become accustomed to three levels. If they go to the heart of the city on rail they will be on one level. If they take their motors they will speed along on a street level designed exclusively for wheeled vehicles, and if they seek to walk about the heart of the metropolis then they will confine themselves to the foot level.

121 Rotary Wheels Carved in Gold

ONE hundred and twenty-one cog wheels of solid gold, all turning as one, is one of the latest novelties in the mechanical line. These golden cogs were made for the Rotary clubs of California at an expense of several thousand dollars, the gold alone being worth $1500, without the workmanship, which involved an enormous amount of en-graving. The wheels are each engraved with the name of some city in the United States and Canada.

I Walked Through FIRE

By Wilmon Menard

That red-glowing pit on the South Sea island fascinated the author. He never thought he’d be lured into the flames.

“YOU’RE going to be sorry!” shouted one spectator as I kicked off my shoes and stood before the fiery pit.

A moment ago I had been just a sightseer standing among the spectators gathered in a sacred grove on the South Sea island of Raiatea to witness a strange fire-walking ceremony. Now I was feverishly getting ready to walk barefooted through the fire myself.

The Truth About… Our Weather and the A-Bomb

Many people, including weathermen, are inclined to believe that the atomic blasts are the cause of the vicious tornadoes, hurricanes, wind and rain storms that have swept across our country. MI Editors asked Eric Sloane, noted meteorologist, for his opinion. Here’s what he has to say.

THERE’S little doubt about our changing climate. The fierce winters of yesterday are disappearing, tornadoes and hurricanes are becoming more vicious and weather trends aren’t trends” any more. They can’t be depended upon. Just about anything can happen—and does.

Paste-Pump Toothbrush

A MISSING tube of toothpaste helped Dr. L. E. Walker, a Mullen, Neb., dentist, invent a toothbrush that always had the paste handy—packed right in the handle.

Dr. Walker’s office was full of professional equipment for taking care of other people’s aching teeth. At home, though, it was another story. When he had to clean his own grinders, he found his toothbrush all right—but where was that wandering tube of paste?

Ads Stenciled on Walk with Water

AN INGENIOUS device which paints signs on the sidewalks, but which in no way permanently defaces the street, is used by a Barcelona wine merchant to advertise his products. The ad painter consists of a large rolling drum filled with water and enveloped in a stencil. As the drum rolls along the water emerges around the stencil and paints an outline of the letters on the walk. As the water evaporates in a short time, no damage is done. No signs, however, can be painted on a rainy day.
