The Last of the Explorers (Jun, 1934)

The Last of the Explorers

THE adventurers of this century are the archaeologists. Theirs is the thrill of finding the new, the strange, and the startling. Trekking through jungles, skimming alligator infested streams, plowing through sands, delving in old caves, the modern archaeologist can find more thrills than the big game hunter of Africa or the airman of the ocean’s watery wastes.

The Great Wall of China to be Motor Highway

The plans of the Nationalist Government of the Republic of China for converting the great wall into a major motor highway are revealed to the world for the first time in this exclusive story.

SCIENTISTS, turned showmen, are displaying an amazing $44,000,000 spectacle at this year’s version of the Century of Progress in Chicago. Actually the World’s Fair is depicting 101 years of progress. In that brief period of twelve months man has moved forward rapidly.

The marvels of his achievements are recorded in more than 100 new attractions in the second act of this great show. Except for a few outstanding buildings, the visitor will scarcely be able to recognize last year’s fair. A new panorama of color, new buildings, a resplendent lighting system, original, thrilling, and amusing attractions, and a dramatic review of the world’s latest accomplishments—all are combined in this mammoth exhibition on the shores of Lake Michigan.

The New Century of Progress (Jun, 1934)

The New Century of Progress

HOW would you like to make a trip around the world in a day, stopping for an hour or two in England and Prance, seeing the sights of Italy, Spain, Ireland and Switzerland, paying a visit to Germany and China and catching a glimpse of such out-of-the-way places as Tunis and Morocco ?

This is part of the lure of the Century of Progress for 1934 which has been transformed into an international exposition by adding to the wonders of industry and science shown last year more than a dozen foreign villages, each a faithful miniature of the nation it represents.

These foreign communities, depicting the architecture, industries, customs and dress of most of the principal countries of the world, will give visitors an insight into other nations which could be obtained otherwise only by expensive travel or by weeks of intensive reading and research.



by Ebe Alongi, M. D.

In sex — as in every other aspect of human endeavor — there are giants as well as pygmies.

IN most books on health written in the past, men were almost always advised to have only moderate sexual contact with women, if they wished to have physical and mental vigor. This advice was especially to be applied at certain times of life and in certain circumstances.

Dr. Alongi is assistant at the University Clinic for Nervous and Mental Illnesses of Naples University and, for a number of years has been Official Consultant on psychiatric and neurological problems of the Court of Justice and the District Court of Naples.

Even if one were to grant the correctness of this counsel, we run into difficulty. The moment we ask: “How many times in a month can a man safely sacrifice to the goddess of love?” we find that no one answer can be given for all men.

Exposition for Inventors Attracts 3,000 Designs (Jul, 1931)

Exposition for Inventors Attracts 3,000 Designs

A FIELD day for inventors was the International Fatent Exposition at Chicago a few weeks ago. Hopeful designers of more than 3,000 devices showed off models of their inventions. Meanwhile, prospective buyers of patents strolled through the rows of exhibits. On this page are shown some of the novelties of the show. Evidently the scheme to bring inventors and buyers together was successful, for another inventor’s exposition is planned for September.

Will You Lose Your Job Because of A New Machine? (Mar, 1931)

Will You Lose Your Job Because of A New Machine?


AN ENGLISH watchmaker’s apprentice named John Kay, in 1738, invented a flying shuttle for weaving cotton. This was the first modern labor-saving device and with its aid, one man could do the work of two.

To the amazement of the young inventor, a roar of protest rose from the English weavers when it was introduced. Thirty years later, Kay aided in the development of a second labor-saving device, the spinning jenny. When this was installed in the English cotton factories, riots broke out.

An American manufacturer named Lloyd Raymond Smith, president of the A. 0. Smith Corporation put into operation at Milwaukee, Wis., in 1920, an automatic plant for making automobile frames. His monstrous machinery turns out steel automobile frames at the rate of 10,000 per day—one every eight seconds of the day and night. ‘ Two hundred men do the work of 2,000. Only fifty of them actually touch the frames. Without doubt, the Smith plant is the most complete instance of the use of labor-saving methods to be found in the world.

In such cases, when the idea was a winner, we gave the award to the writer of the letter with the earliest postmark.

The Age of Man-Made Rubber (Jun, 1936)

The Age of Man-Made Rubber

CHEMISTS’ dream of making a better rubber than nature can produce has come true. Barely six years after the first commercial production of synthetic rubber in the United States, the industry now functions on a million-dollar scale and hopes to reach the billion-dollar class before the end of the next decade.

There are two synthetic rubbers being produced in the United States. One called thiokol is manufactured by the Thiokol Corporation, and the other, duprene, is a product of E. I. du Pont de Nemours & Co., Inc. Thiokol is the discovery of Dr. J. C. Patrick and has been on the market since 1930.
