I’m not sure it would be possible to design a worse set of earphones…
EAR TUBES FOR PHONE MAKE WORDS DISTINCT
Persons hard of hearing, who have difficulty in carrying on a telephone conversation, are said to be aided by the new set illustrated above. When answering a call, the user places a receiver of conventional design (at right of photo) upon the base of an instrument resembling a physicians’s stethoscope.

Update: Stannous points out in the comments that the kids on page 4 appear to be members of the Hitler Youth.


Toys for Men Only
WORK is mere play for the research engineers. At least, that’s how any small boy would look at it if he saw these grown men tinkering with toy trains and planes, boats and automobiles, electric motors and compression engines.
But if you could examine all the playthings of all these engineers, you would enjoy a glimpse into the world of the future, for the toys of today are working models of the mechanical marvels of tomorrow—reflections of engineering visions.
Toys have had a profound effect on human progress. The gyroscope, for example, was merely a toy until its properties were applied. Then it grew up to fly airplanes and steer ocean liners. Boys sent electric trains dashing around toy tracks long before railroads used electric locomotives, and operated toy machines with miniature electric motors while the wheels of industry still were being turned by steam.

How does one rob a radio wave of it’s “vital properties”?
Scientist Finds Stratosphere Hot
A STRATOSPHERE of 1,000 degrees Centigrade 150 miles from the earth is reported by Prof. E. V. Appleton, British radio authority, who bases his theory on the reactions of radio waves sent 150 miles straight up. The waves were undoubtedly affected by an intense heat which robbed them of their vital properties, he reported.
