Science has devoted considerable thought and experimentation in the hope of devising a reliable lie detector, and some interesting results have been announced in various directions.

The latest researches have been made known by Dr. Boris Orlov, a Russian psychologist, now living in Paris. Professor Orlov asserts that modern fashions, by exposing women’s necks, have incidentally exposed their minds. When a woman is not telling the truth, he insists, she will blush in the area just below the breast bone.

Dr. Orlov calls this telltale area the “zone of veracity,” and his book, “La Pseudologie Humaine Normale et Anormale,” offers a number of other interesting tips for the casual detection of untruthfulness. This “zone of veracity,” Dr. Orlov says, is a sort of window through which certain well-disguised feminine mental processes may be seen…

“When a woman lies,” Dr. Orlov continues, “there is inevitably a nervous tension inside her. During the mental stress of lying, this tension is communicated to the vasomotor nerves which control the arteries and capillaries in the skin.

“Blushing in any part of the body is produced by an increased flow of blood into the capillary vessels serving the parts where the blush extends. The area affected is not only reddened, but there is a perceptible increase of heat there.

“The interaction between mind and body is close. A nerve filament from the sympathetic system lies along the sheath of and parallel with each artery and capillary, controlling the expansion and contraction of the muscular coat of the vessel. This is the vasomotor nerve. The mental agitation produced by lying causes temporary vasomotor paralysis and an ensuing rush of blood into the capillary vessels of the skin, which we call blushing.

“A self-controlled deceiver can inhibit blushing in the face. But the feminine fibber’s throat, her upper thoracic area, will visibly palpitate and redden. A throbbing or fluttering will be seen in the area about the breast bone. The blushing will usually cover a space two to three inches in diameter. In many cases, this section of the throat or bosom will redden though not a trace of a blush will color the cheek.”

An experimental model of the 'Taste Organ,' which was developed by a French scientist. To enjoy the taste 'harmonies' the 'listener' holds a small tube in his mouth so that the various concentrated liquids can be injected either singly or in the correct combination.

Wooden houses may not be known in 2020. The street cars, railroad cars, and other familiar methods of travel doubtless will have passed the way of history a century from this hour. Out of all the agencies which men use today electricity alone seems likely to survive. Many scientific men believe that coal and gas will have passed out of common use within the century.

Some one has suggested that the air and the water will furnish us our methods of heat and power in 2020. No one can doubt but that the flying machines of a new and important type, not known today, will be in general use a century removed.

Airplanes probably will be driven by electricity with storage batteries providing the power. Gasoline is not likely to be utilized in 2020. The fuel problem will be solved in a far different way than it is solved now. The air will provide an immense motive power for various things. The sun, doubtless, will be called upon to furnish the greater portion of the heat utilized by manking. Out of the waters on the face of the earth something will be developed for the benefit of the human family.

The automobile will be succeeded by something entirely different. Horses and cows may not be known.

Students of the human race have told us that the primitive man, like the primitive animal, was great in stature. The bones that the scientists have unearthed have verified this. Maybe human beings a century hence will become either much smaller of much larger than they are today. Everything will have changed.

A century past has given us an unlimited amount of great inventions, the sewing machine, electric irons, electric washing machines, airplanes, automobiles, radium and electricity. The next 100 years will see this process of enlargement carried on until it reaches even greater heights.

It may not be a cheerful picture to paint, but most of us will not be here to see the year 2020 roll around. But we can rest assured time will bring changes and improvements. This is a progressive earth and progress has marked each succeeding year since the beginning.

Only the other day there came from Denver the startling news that the young women of this western city were wearing dog collars for engagement rings in lieu of the conventional band of gold, silver or diamond-set platinum. To further emphasize the departure from tradition, the girls wore this romantic token around their legs, as shown in the photograph of Miss Fay Rowe, of Denver, on this page. Thus the engagement ring-dog-collar became a garter as well as a symbol of betrothal, combining utility with romance...

The custom was started by a young woman in one of the college sororities and it spread rapidly. It was generally believed to be something entirely new in the way of betrothal tokens, but had the young woman been a careful student in her history class she would have known that the fad she started was an old one long before the Christian era was born. Jeweled anklets have been discovered in the cinerary urns of the ancient Greeks, with inscriptions which indicate they were tokens of engagement. Bracelets were also common in all ages as tokens of betrothal...

The principal objection to the dog-collar engagement token around the leg seems to be, "What's the use of wearing an engagement ring without anybody seeing it?" To which the answer is, "Nowadays a ring worn about the leg can easily be seen with the skirts of women growing shorter and shorter."

Now arises Mrs. Lydia McPherson of Los Angeles, California… Her friends claim that if Lady Godiva had possessed hair like Mrs. McPherson, she would have been more than adequately attired in her famous ride through the streets of Coventry. Mrs. McPherson surpasses Mother Eve, by wearing, as her picture shows, only nature’s covering, whereas the world’s first lady had to borrow from the fig tree. The tresses of Mrs. McPherson measure seven feet two inches from root to tip, and are of a find, bright red color.
