WHAT if you were locked accidentally behind the thick walls of a steel bank vault? Can you imagine the horror of shouting vainly for help; the agony of the long night hours of waiting, with hope ebbing and the torture of slow, suffocating death creeping upon you?
AT THE bottom of the sea the plants are animals. Strange though this may seem, science proves it to be literally true. Vegetation is to be found only near the surface of the ocean. The flower-like life of its vast depths, rivaling in beauty the choicest products of the greenhouses and cultivated gardens of the land, is animal life.

THE subject of evolution is like this round ball that we live on and call the earth—it is so vast that no man can see more than a little of it at once. To any single human eye the earth seems nothing but a broad, flat plain more or less wrinkled with mountains and scratched here and there with lakes or rivers.
THE most important rule for the radio fan to learn in building his own set is that in the reception of broadcast wave lengths inductance is more important than capacity. Since inductance is obtained from coils of wire, and capacity from condensers, it follows that he Will have to use as much of his coil and as little of his condenser as possible.

A vacuum cleaner stirs up less dust; it does the work in vastly less time; it is operated easily and it leaves no pile of sweepings to be gathered up.

TO MOST of us the plumbing systems in our homes are like our teeth—we do not realize that we have them until something goes wrong. Then, when something does go wrong, we are quite helpless. Even the handy man who does a little carpenter work and painting about his home and perhaps tinkers with his automobile rarely will attempt to repair his plumbing, simply because he thinks that plumbing work is difficult and mysterious, requiring a very special kind of skill and unusual and complicated tools.
AS I was walking down the steps of my home one morning early last December I saw a neighbor standing at the curb. He was gazing with pained expression at his automobile, a smart car of a well known make, bought only a few months before. As he heard me approach he looked up and pointed silently toward the front of the car.
BY THE relatively simple modification illustrated in Fig. 1, an auto steering wheel of the usual fixed type can be converted into a hinged or tilting wheel. This applies, however, only to a car on which the spark and gas quadrants are not mounted on the wheel.
MAKING toys for the kiddies’ Christmas is the most enjoyable work that comes into the home workshop. Every man who is in the least handy with tools likes to build playthings. It is fun to put them together; they always seem to turn out successfully; and they are immensely appreciated by the children.
NOTHING could be more in keeping with the Christmas spirit this year than the presentation to the household of a good, reliable radio set. The joy that such a gift will bring to every one in the family is certain to be lasting. The radio set offers a solution to the question, “How can we make evenings at home enjoyable enough to compete with the club and the movies?” For ease of construction, simplicity of operation, and general all-around efficiency the double-rotor type of tuning unit has few rivals.
MANY short cuts are possible in laying or lining out work in the machine shop. Presumably the regular layer-out and the shop foreman know most of them, but the machine hand or floor hand, no matter how much experience he has had in his particular specialty, often runs into all sorts of difficulties when he is called upon to lay out work.

As THE milling machine has no arrangement by which the table can be thrown out of the horizontal, it is often useful to have a special tilting table for tapered work, such as taps, reamers, and the like. The table should be as wide as the index centers with which it is to be used.
THE frame of the old car again is suspended from the springs. The wheels are again on the axles. The transmission system is installed again on its bearings, and the engine, separated into its component parts, is lying on the bench. Before reassembling the motor, look carefully at each part.

THE advantage of having a fireproof and, if possible, secret container in the home for deeds, notes, valuable papers, jewelry, and silver plate, can hardly be overestimated. Any one who has been through a fire or suffered a burglary knows the dollars-and-cents value of a good strongbox.

A sure-fire Christmas remembrance for the “go-getters”
The man-to-man gift should be something of a friendly, masculine sort— and something that doesn’t presume too much upon personal tastes. Men don’t like to be sentenced to wear neckties, scarf-pins, or other adornments of another’s choosing.
Yardstick Set in Bench Serves for Rough Measurements
IT IS Christmas and the room is dark. A square of light is seen through the door; this reveals a miniature stage. Slowly the curtain rises. A tropical shore is seen in the white light of the Southern sun. The sky assumes the fiery hues of a tropical sunset.
CHRISTMAS trees in Europe, where so many of our Yuletide customs originated, are usually gathered and sold with the roots attached. They are then set up in a large pot or tub, according to size. This has advantages, from a picturesque standpoint, over the American practice of mounting Christmas trees on a stand of two crossed sticks.
IF YOU are interested in skiing, which is becoming more popular every winter, you can make quite easily a pair of skis that will look well and give excellent sport. The raw material consists of a spruce board 6 ft. 6 in. long, 8 in. wide, and ¾ in. thick.
No HOME work bench or tool cabinet is complete without a number of files of different sizes and shapes. For an all-around set of files for the home, I should suggest the following: 10-in, flat wood file 10-in, hall-round wood file 10-in, hand file, second cut 10-in, hand file, smooth 6-in, hand file, smooth 8-in. pillar file, second cut 10-in. hall-round, second cut 6-in. half-round, second cut 6-in. round, second cut 6-in. handsaw file, double cut, second cut This set with handles would cost, I estimate, about $7.
