EVERYBODY in America wants an automobile." It is less dangerous to make that generalization about the universal desire for, a car than about almost any other semi-luxury. With over ten million automobiles in use, there are still more people that want cars of their own.

THE problem of getting enough coal for this winter is vital in nearly every house in the land today. Whatever efforts are made to increase coal production this fall, it seems inevitable that we shall have to get along on short fuel rations. Coal economy becomes, therefore, a matter not only of money saving, but of actual physical comfort.

IS EINSTEIN’S theory of relativity about to be consigned to the scrapheap? Breaking upon an astonished public some three years ago, turning our conception of the universe topsy turvy, seeming to be completely accepted by scientists, it now appears possible that the theory of relativity may have to be considerably modified as a result of remarkable experiments with light rays carried out in California, on the top of Mount Wilson.

THE greatest question in the motion picture world today is whether or not the pictures of players in the movies should be given voices and made to speak their parts like actors on the stage. While many artists, motion picture experts and writers assert that the power of the silent drama will be damaged if its silence is destroyed, scientists in three countries have lately made such remarkable progress in photographing and reproducing voices on movie films that it seems certain the coming of speaking photo plays—whether we want them or not—cannot be long delayed.

THERE is apparently a grave fuel emergency approaching. I believe that it will sharply awaken the average American to the costly inefficiency of his domestic heating plant. "The homes in which our families live 24 hours a day certainly deserve more attention from heating engineers than the office buildings in which we spend only eight hours a day.

PHOTOGRAPHS deftly reproduced in basrelief out of ivory, alabaster, or wood, a few hours after a sitting, are the outcome of an extremely ingenious method of photo-sculpture invented by Howard M. Edmunds, of England. By this device the tedious hours of posing for a sculptured relief or a bust are eliminated.

WE AMERICANS spend every year tens of millions of dollars for perfumes, scented cosmetics, and toilet soaps having an odor we like. But we spend many times that much to get away from odors we do not like. The actual property loss in the United States due to public aversion to certain odors is more than $2,200,000,000!

BALDNESS is definitely on the increase in the United States, and is more characteristic of the American than of the European, according to recent observations by the medical profession. In the large cities of the United States is to be found a greater percentage of prematurely bald heads than in any other region on earth.

WHEN your engine goes dead, how long does it take you to locate the seat of the trouble and get under way again? I am willing to wager you have often spent anywhere from 10 to 20 minutes in unsystematic fidgets over the situation—and perhaps have even resorted to the expense of calling a trouble car from the garage.

EVERY one who makes or buys a radio receiving set soon becomes curious to read the code messages that he can tune in at any time of the day or night. These messages, he quickly learns from other more experienced radio fans, are often most interesting—news despatches, witty interchanges between amateurs, messages between ships and shore stations, army and navy despatches, and all kinds of wireless traffic.

PROPER lighting contributes much to the comfort, charm, and individuality of a living room at night. Poorly placed lighting fixtures of crude design, throwing either too much or too little illumination, will counteract the effect of furnishings that are in the best of taste.

THIS ready-reference chart tells all about I-beams almost at a glance. It serves more quickly than a table for solving many problems of frequent occurrence in construction work and gives close results for regular standard beams. For “special” beams, however, caution should be exercised in applying it.

Joe V. Romig
FOR very accurate reaming work, floating reamer holders are used because they allow the reamer to adjust itself to any slight misalinement between the bore and the true axis of the lathe spindle. Reamers held rigidly will invariably trail a mark through the bore and also they are apt to cut large and untrue.

EVERY home worker who has ever attempted to do artistic handiwork and is interested in the decorative crafts, finds continual difficulty in obtaining good designs for use as ornaments. This is equally true in regard to stencil ornaments for woodwork, designs for tooled leather book covers, patterns for textiles, or ornamental units and borders for handmade jewelry, hammered brass and copper work, wood carving and embroidery.

J. M. Rolston
IN CHANGING from short to long wave reception I make the necessary circuit adjustments in my radio set quickly and easily by using a Ford panel switch. This permits me to use a variocoupler type of tuner for broadcasting, and various sizes of honeycomb coils for the long wave stations.

Made $456 in a Month Digging Wild Horseradish

C. O. Soots
MAKING a neat little extra income by digging wild horseradish may hardly qualify under the terms of the contest, “How I Made Money with Tools,” especially since the tools I used were only a spade, grubbing hoe, and hatchet.

AUTUMN is the time when the big fish bite and when your chances are good for catching a prize-winner. When you have made the big catch, mount it, and it will be one of your treasured possessions. It is not difficult to skin the small-mouth bass (Fig. 1).

WHEN window and porch screens are taken down in the fall, they should be marked in some way so that they can be readily replaced the following season. There are a number of good methods for accomplishing this. One way is to punch marks on the top or the bottom edge of each screen with a screwdriver or chisel, following a uniform system throughout.
