ALL outdoors is the studio of Remington Schuyler, the noted American Indian painter; but nowhere, we think you will agree, has he portrayed the tingling thrill of winter more masterfully than in the painting on the cover of this issue. If this picture makes you want to build a winged toboggan and try it on the nearest hill, your enthusiasm will be doubled when you read the graphic description of this fascinating new winter sport by its originator.

Separating the Good from the Bad in Battery Chargers

Prof. Sampson K. Barrett
WITH the many powerful radio sets now in use, the majority of which operate most satisfactorily on storage batteries, the selection of a good battery charger is an important problem to many. It is most essential that the batteries be in first class condition if the receiving set is to give reception of the first order.

THOMAS L. MASSON
ARE you curious? Why? When? Where? In the rear of my country home in New Jersey is a miniature house, built twenty-one years ago. A small, square house with a peaked roof, about fifteen by fifteen. It remains unchanged from the time of its birth, except for a new roof.

Flaps Its Wings like a Bird
Amazing Autogiro Can Land Almost Vertically

Arthur A. Stuart
AT FARNBOROUGH, England, a few weeks ago, a group of aeronautical engineers and aviation enthusiasts assembled to witness an event that may revolutionize completely the future development of the art of aviation. An odd, awkward looking flying machine, topped with a windmill arrangement that flapped like the wings of a bird, rose swiftly from the ground, accomplished a trial flight of almost 50 miles, and then returned to its starting place, dropping almost vertically and coming to a full stop within 20 feet of the place where it first touched the ground.

John R. McMahon
EDISON in his seventy-ninth year is running short of time—has to sleep so much now that his working day is limited to a pitiful 16 or 18 hours. He needs every moment of that short day for his important activities. That’s why he has practically quit giving interviews and why he felt that he was doing a considerable favor recently when he talked to me awhile for POPULAR SCIENCE MONTHLY.

WILL the faces of our descendants —of our grandchildren’s grandchildren—look anything like the rather queer illustration on this page? Will men of the future have small, cramped brains; sparse hair; long, thin, and prominent noses; tiny, “precious” mouths; narrow, squinty eyes; and no jaws or cheek bones to speak of?

THE total eclipse of the sun last January presented to thousands of us the opportunity of witnessing a spectacle whose awe-inspiring splendor we shall never forget. Darkness creeping over the snow; weird, flickering shadows that appeared from nowhere; the dazzling sun gradually obscured until at a breathless moment the greenish gold corona leaped from the rim—these are the memories of a lifetime.

EARLY one morning several months ago I was riding a sleeper on a flying trip from an Ohio city to New York when I was rudely jolted awake by a sudden grinding of brakes and lurching of cars as the limited came to a full stop. It so happened that the train had been speeding me to an important engagement in the metropolis that morning; and so, as I peered wide eyed into the darkness, it was with a feeling of dismay, a few moments later, that I heard the word passed down the line that there was a wreck ahead.

IF YOU live in a growing city, no doubt you often have watched workmen demolish an old house or business block to make room for new and larger buildings. In the crash of tumbling debris there is a strange fascination. In a few hours the work of months, sometimes years, can be reduced to broken brick or stone, shattered timbers, lumps of plaster, and crooked nails, fit only for the dump heap.

George Lee Dowd
WHEN, last fall, a strike shut down the anthracite coal mines, people who had been accustomed to burn this fuel were thrown into a state of panic. Many probably believed that they were likely to be frozen to death before the end of winter, because the impression prevailed that bituminous or soft coal, the most available substitute for anthracite, is an unsatisfactory fuel for domestic purposes.

NOT infrequently, projectiles figuring prominently in criminal cases will reveal upon their surfaces abnormalities that may have been caused by defects within the barrels through which they have passed. Such a point was at issue in the recent murder trial of Gerald Chapman, and there existed considerable difference of opinion as to the actual causative agent that had produced certain markings on bullets in evidence.

WOULD you believe it possible to fry an egg in a frying-pan held over a cake of ice? To demonstrate that it can be done, Bernays Johnson, well known New York radio engineer and inventor, recently devised the apparatus pictured at the left. The probable explanation is this: Beneath the table top is concealed a coil of wire through which high frequency current is passed. When the frying-pan is placed in the magnetic field of this coil, an electric current is induced in the iron of the pan, heating it sufficiently to cook an egg.

WHILE many men are interested in model railways, their particular fields of activity are not all along exactly the same lines. One man will spend most of his time on the production of locomotives. Another may be interested in the rolling stock of his model railway and a third, perhaps, may tackle the problems connected with control, signaling, and operation.

Sharpening Your Skates
Five Ways to Give the Runners a Keen Edge
[no value]
[no value]
Lawrence B. Robbins
ALL the real fun of skating is lost if your skates are dull. Worn runners mean side slipping, uncertain footing, and consequent loss of speed in racing or during ice games. It behooves the true skating enthusiast, therefore, to keep his skates well sharpened.

Could You Whittle a Broom with Your Pocket-Knife?
Splicing a Broken Torque Tube

Herbert I. Childs
FOR one who has a keen pocket-knife and knows how to use it, it is no trick at all to whittle a whisk-broom. It is a good project for the whittler to try occasionally, when he has an odd half-hour to spare, as a test of his ability to make clean, thin, slicing cuts, and it makes a neat demonstration by which the home worker can display his virtuosity with a penknife.

Riding an Ice Chair Is Novel Sport for Skating Parties
[no value]

[no value]
G. EVERETT VAN HORN
WHEN the ice is thick enough for skating, you can have a lot of sport by equipping a common folding camp stool with runners to form a skater’s chair. The runners, which are strap iron or even wood, are bolted to the legs of the chair. The occupant of the chair sits with his or her skates directly in front and must grip the chair firmly so as to present a stiff back to the one who is pushing from behind. When not in use on the pond, the chair can be used near the edge by those who wish to rest or remove their skates.

IN THE junk pile there is often some discarded machine that can be converted into a forge. In this case an old cream separator was used. A fan was made and mounted in place of the bowl, with a bicycle hub for ball bearings. The axle was connected with the high speed shaft and, as there is a friction clutch in the machine, the handle can be worked as a lever without turning it all the way around.

Cut the cover around on a line halfway from the outside to the center so as to reduce its size and weight.

EVERY home mechanic, no matter if he specializes in wood or metalworking, often has occasion to make a working drawing, sketch, or layout. For such work it is helpful to have a well equipped drafting-table. A good model is that illustrated, which is remarkably rigid, considering how light the construction is.

ALTHOUGH a violinist usually goes to a violin-maker to have a new bridge fitted to his instrument, the work can be done by almost any one. Place a piece of No. 000 sandpaper, as shown, with the abrasive side up, and move the bridge from side to side until the legs are sanded down sufficiently.

KEEPING the floors of a home shipshape is a perpetual problem, especially if the wood is of a poor and splintery quality, or if the floors have been abused or neglected. When the floors are in really bad shape, they must be relaid. Fortunately that is not a difficult job.
