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.

How an Invisible Lifeline Rescues Men from the Sea
A Story of Heroism Made Possible by Wireless
WHEN the Italian freighter Ignazio Florio was pitched and tossed a few weeksagoin the mountainous waves and cavernous depths of the worst storm an angry Atlantic has concocted in many years, it was an invisible lifeline that held out hope to her badly battered crew.
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.

Our Descendants Will Have Cramped Brains, Pinched Cheeks, Long Noses, Squinty Eyes, Says Noted Evolutionist
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?
What I Have Learned of Venomous Serpents at the Strangest of Reptile Farms—A Cure for Deadly Bites
TAKE this fellow, for instance—if he nipped you he’d leave enough poison in the wound to kill two or three men. You would die in fearful agony before nightfall. Your limbs would be swollen to twice their normal size, and your face distorted out of all semblance to your former self.”

ONE day recently a young man came to me discouraged. “I simply haven’t any memory,” he complained. “I never seem to be able to remember a thing I read.” “Perhaps you haven’t given your memory a chance,” I suggested. “Suppose we test it.” I tried him with numbers.
A Veteran Tells How the Wrecking Crews Clear the Track—A Week's Work in a Few Hours
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.

Every Scrap of Wreckage—Even Bent Nails—Can Be Put to Use
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.
It's Just as Good as Anthracite for Your Furnace when You Know How to Handle It
A Daily Schedule for the Operation of Your Furnace
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.

MANUFACTURED gas that is said to give twice the heat and light value of any gas now used, was announced recently by Col. E. E. Garrison, president of a New York gas company. It is made by vaporizing the heaviest oils obtainable, including sludge and tar, in a column of superheated steam.
THE spark plugs in your automobile have but one function —they provide a small gap between two metal surfaces or wires so that the high voltage current generated in the spark coil may jump the gap and, in so doing, heat the gasoline and air mixture so that it will ignite.
DISPROPORTIONATE to its size is the power of this unique plane saw used in the forests of France to topple towering giants. One of its most interesting features is its portability, which makes it possible literally to carry the sawmill directly into the forest.
YOU use a spoon to fill this new powder puff. Once filled, the slot through which the powder has been poured is closed so that the puff will not leak. When the puff is patted, the powder comes out of small perforations in the wool. The chief advantage claimed for this beauty aid, besides being a powder container, is that it has a back of rubber and the wool powdering surface may be washed very easily.
FROM the South Sea Islands every year hundreds of tons of copra—dried meat of cocoanuts—are unloaded at the San Francisco docks. A giant “vacuum cleaner,” recently installed, now does the work of unloading, taking the place of a crew of 25 laborers.

IN THE beautiful land of yesterday, when the writer and his compatriots were barefooted boys, perhaps none of us was rich enough to own a chest of tools; at any rate, none of us did. The writer can well remember when his older brother gave him a gouge or halfround chisel.
PLAYING and racing with death down a 1000-foot slope of frozen snow and ice may not appeal to some as a pastime, but the palling monotony of life in a Colorado mining camp, up on the Continental Divide, where the snow is 50 feet deep and the mercury is below zero for months, makes life seem very drab.
You have said good-bye to Yesterday, with its failures and disappointments. A new Tomorrow lies ahead of you. What are you going to do with it? To the man who gives little thought to his business progress, one day is much like another—filled with routine work—rewarded by routine pay.
Burnishing Broach Gives High Polish to Brass Bushings
H. L. WHEELER
JUDGING by the cars he recognised, as he stopped his flivver in the yard cf the Robinson Mill, Old Bill thought he must have been summoned to attend a convention of all the mechanical men in town. He was a bit peeved, too, as there was much work to be done at the shop.
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.
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.
Ornamental Cutlery Handles Made from Odds and Ends

Riding an Ice Chair Is Novel Sport for Skating Parties
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.
AFTER refinishing a breakfast room suite, I hunted unsuccessfully through the stores to find a folding screen that would harmonize with the furniture and at length built a screen of my own design.

SHOOTING arrow parachutes is a sport to thrill young bowmen who are looking for something novel in the way of archery. Remove the cover from an old umbrella, being careful not to rip the cloth. Cut the cover around on a line halfway from the outside to the center so as to reduce its size and weight.
OLD picture frames, glove or work boxes and similar pieces may be decorated easily with imitation carving. Rice is boiled in water to make a thick paste and mixed with starch to a doughlike mass, which is rolled into sheets, cut into squares, and allowed to dry.
IN ANY home workshop, kitchen, or laboratory where flasks, jars, and porcelain-ware are filled with hot liquids, the danger of breakage may be lessened greatly by the use of a stand made by fastening corks with glue and nails to a wooden baseboard.
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.
WHILE rattling doors, which cause annoyance in many houses, can be fixed by the method of moving the strike plate in the door jamb toward the door stop just the right amount, it often happens that the amount of play in a door is so slight that one wishes for a still simpler remedy.
Tricks that Are a Help in Repairing Roller Bearings
J. V. R.
ASSEMBLING roller bearings of the spiral type usually can be accomplished quickly if advantage is taken of several little kinks that simplify the work. Before slipping a housing over a bearing, the rollers open up and will not enter the bore.
IN THE experimental department of a large plant in Philadelphia, the hydraulic engineer required a ¼-in. hole drilled in a piece of copper, as in the lower view. This was accomplished by first making a templet and bending the copper, as shown in the upper view.
Two Cheap Tap Wrenches Used in Making Trammel Points
Gang Tool-Holder for Facing Shoulders on a Lathe
TWO tap wrenches bought for 25 cents each were used in making the machinist’s trammels illustrated. The wrenches are clamped to the beam, which is flattened on top, by means of knurled screws. One point has an auxiliary screw for fine adjustments.
FROM the standpoint of the machinist or toolmaker who has to make a sine bar, the design illustrated below has the advantage that there is no danger of grinding and lapping the center distance under size, which would entail scrapping the work.
PORTABLE lamp cords, air hose, and other flexible lines, such as those carrying coolants to machine cutters, often are fastened temporarily in place with bits of wire or pieces of cord, although the practice admittedly is not workmanlike.
FOR the garage man or other mechanic who has a great many brake band renewal jobs, the press illustrated is well worth making. No patterns or castings are required. All the parts are especially heavy so that the press will stand hard usage and will serve for other purposes.
Clamping Fixture for Filing Small Pieces at an Angle
FILING an angle on a large number of small pieces often may be made easier by the construction of an auxiliary clamp or fixture of the type illustrated. This is a piece of flat steel bent to suit the work and held in the bench vise. The bend should be such that the two sides of the fixture will be approximately parallel when the vise jaws are closed upon them.
Elliptical Shaper Tool Insures a Smooth, Shearing Cut
CQUARE-NOSED tools tend to dig in ^ when finishing tool steel, or alloy steel in the shaper or planer, which makes it difficult to produce a smooth surface. The tool shown, if used for this purpose, will insure a good finish.
GEAR blanks or similar work/ may be handled very rapidly and accurately for facing or reaming in the chuck illustrated, which is gripped in the usual four-jawed chuck. The spring hole is drilled, the end split, and the clamping screw is put in before the the hole for the blank stock is bored.
ON OCCASIONS when it has been necessary to bore a tapered hole with a milling machine, I have used the method shown in the upper view of the accompanying illustration. The guide bar was set on an angle corresponding with the desired taper and fastened to the milling-machine table in the most convenient manner.

DRAWING screw threads, which is a time-consuming detail in the work of every mechanical draftsman, can be expedited by the use of a templet made as shown of celluloid, wood, or hard rubber. A piece of material 1/16 by 4 by 5 in. makes a templet of a handy size, but the dimensions can be larger or smaller, to suit the individual requirements.
FOR facing small pieces in a lathe, the expanding chuck or collet illustrated below is especially useful. A length of round stock is turned at one end to suit the work to be held, the reduced section being slightly shorter than the thickness of the pieces.
