1916 Acousticon

Deaf? “I Now Hear Clearly” You. Too. Can Hear!

Inasmuch as 200,000 users of the “ACOUSTICON”have had the same results from it as Mr. Garrett Brown, whose photo appears above, we feel perfectly safe in urging every deaf person, without a penny of expense, solely and entirely at our risk, to accept a thorough trial of the 1916 Acousticon.

The Truth About Petting

By Lawrence Gould, Consulting Psychologist

Is Petting Right or Wrong? How Much, if Any, Seems Wholesome?

This Clarifies a Problem Perplexing Both Youngsters and Parents

MRS. HUNTER had appeared so radiantly happy the last few times I had met her that it was a shock to see her looking as she did that morning. I had known her slightly for several years as assistant to the manager of the building where I had my office, and had heard her story from the manager and some of the other tenants. Her husband had died ten years before, leaving her with an eight-year-old daughter and only a few hundred dollars of insurance. She had gone back to the work which she had done before her marriage, and by dint of industry, intelligence and self-denial had managed to make a comfortable home for Mary. The girl was in every way a credit to her, gay and carefree, but devoted to her mother, and both faithful and successful in her studies.

Treadmill Propels Child’s Wagon
Walking on rollers that are geared to the rear wheels of a novel treadmill wagon, a child can propel the odd vehicle along the ground. Invented by Harry Kister, of Philadelphia, Pa., the cart is fitted with removable floor boards that cover the rollers, so that it may be used as a conventional express wagon for transporting small articles. When the wagon is turned upside down, the rollers are exposed, permitting the device to be used as a stationary exercising machine, which is strong enough for regular use by adults as well as by children.

Giant Explosions REPRODUCED IN MINIATURE by Home Chemists

How Blasts of Grain Dust or of Gasoline Vapor Are Caused in Your Laboratory—Tests With Which to Prove a Burning Candle Is a Gas Plant

By RAYMOND B. WAILES

HARMLESS, miniature explosions make experimenting with combustibles a thrilling, yet safe, amusement for the amateur chemist. With inexpensive homemade apparatus, he can duplicate the explosions in a gasoline motor and amuse his friends by burning air. When we say a substance burns, we imply that it combines with oxygen to produce heat and sometimes light. Hydrogen and carbon, as well as many other substances containing these two elements, display this property. A candle, for instance, is made of paraffin, a combination of carbon and hydrogen. When the wick is lighted, the paraffin melts and produces hydro-carbon gases, which decompose to form other inflammable gases and carbon.

Vacuum Tubes and Alloys Bring Back the Harpsichord
Scarcely more than a museum piece since the piano sent it into eclipse, the harpsichord is coming back. Vacuum-tube
amplifiers, twentieth-century mechanics and hard metals have overcome the hand-icaps of the instrument that almost disappeared after dominating the musical world for several hundred years. Piano strings are vibrated by a hammer blow, and the strength of the sound is varied by the strength of the finger blow.

Weird Schemes To Make It RAIN …but they never work

By Robert E. Martin

CHILLING the winds with giant refrigerating coils! Bombarding storm clouds with long-range siege guns! Churning the air with airplane propellers! These are but a few of the hundreds of strange and curious schemes that have been devised to wheedle rain from an unwilling sky. Each year brings its crop of weird plans to combat drought and produce rain when and where it is needed. Some are based on scientific fact, many have never passed the “paper” stage, and others are the fantastic ideas of professional “weather makers,” who even today are able to find credulous customers to pay them for their services.

BIG CROSSBOW HURLS MAN FIFTY FEET
Somersaulting fifty feet through the air from a giant crossbow, a California daredevil recently introduced a new circus thrill. Billed as a human arrow, he takes his place in a small metal cradle and braces himself for the shock of starting. At a given signal, an assistant trips a trigger and the acrobat is hurled into the air and lands in a net fifty feet away. The cradle is driven by a coil-spring mechanism said to exert a driving force of more than 20,000 pounds.
