Ralph Modjeski
ATTEMPTING to select the six greatest engineering achievements of modern times is like trying to name the six greatest men of history. Any list one might make is bound to be merely a reflection of personal opinion, which is quite likely to be influenced by prejudice or individual standards of judgment.

IN A laboratory in Washington, D.

His voice came to me over the radiophone, but for a few seconds I saw him in life size and full detail on the white wall in front of me.

SOME time in the spring of 1925 there will be opened at Ohio Wesleyan University, Delaware, Ohio, an astronomical observatory that will house the third largest telescope in the world. In itself that is a remarkable fact, for Ohio Wesleyan is a relatively small college, having less than 2000 students.

MAN devotes a lot of attention to the air these days. Now that radio concerts are drifting through the air for 24 hours a day and modern Magellans are using the air to circumnavigate the globe in flying machines, the air has achieved an importance never accorded to it in the days when it was employed almost exclusively for breathing purposes.

THERE was a break in the radium market not long ago. The price suddenly plunged from $3,300,000 an ounce to $2,500,000, due to the discovery in Katanga in the Belgian Kongo of extraordinary deposits of a radium-bearing ore, from 25 to 30 times richer than the earth ever before yielded.

TIRED of paying apartment rent and determined to own a home of their own, Jim and Marion Hunter sought the advice of an old friend, an expert on home buying. The story of their search for a ready-built house, of how they found their hearts’ desire, only to discover that the price was beyond their means, and how they finally decided to buy an inexpensive Dutch Colonial house to live in until Jim’s expected increase in salary should materialize— all this was told in the two preceding chapters.

SOMETIMES we must hunch into that old armchair and concentrate on some problem with the aid of books, paper, pencils, ink, drawing tools—inspired by peppermints or a dried-up plug. Such a chair should have a wide arm, with a ditty-box hinged underneath, as illustrated.

HOME workers who are really good craftsmen often are puzzled when it comes to making a design for ornamenting some piece of wood or metal work. They do not like to copy a stock design and yet good original ideas are hard to develop. Individual and interesting stencils, inlays, marquetry, and stained or painted decorations and ornamental ironwork rarely are seen in amateur craft work.

THIS spider-web coil mounting was constructed for an experimental receiving set in which it was desired to change coils with the least possible trouble. Two mounts are used, one stationary and the other movable, and the coils can be snapped in and out instantly, all contacts being made automatically.

Most Edgeworth is sold by word of mouth —one happy smoker will pass the good word along to some less fortunate brother, and a new Edgeworth “fan” is born. Sometimes, however, the human voice plays no part in the spread of Edgeworth popularity.
