WALLACE AMES
OH, HOW I hate the sight of that man,’’snapped out Mrs. Bullard. And well might she feel that way, for he was the installment collector, and he had a way of showing up almost before the weekly pay envelope was opened. “A dollar down and a dollar a week” brought that fine set of books into the home.

H. C. NORTH
LOST at sea! Swallowed completely, without leaving sign or trace to suggest the story. Not one survivor, not a spar nor a boat. Not a word. Just the silence of the sea. And the fate of the ship and all aboard forever remains a mystery. There is something fearsome, something awful, in the thought of a lost ship, which fills the imagination with terror.

WITH magic pipe science has blown for us a bubble—a bubble that for promise and romance far surpasses any iridescent globule ever blown from childhood’s pipe. It is made of glass, but a most wonderful glass, in appearance no different from ordinary window glass but in reality vastly different, because it will transmit more of the sunlight.

Robert E. Martin
CAN you conceive of a universe, other than ours, far beyond the range of the most powerful telescopes on earth today; so far away that its light must travel 500,000,000b years to reach us? And can you visualize a mammoth earthly “eye” so keen as to pierce the borderlands of space, capture the glimmer of unknown stars, and thus read the record of heavenly events as they transpired half a billion years ago?

By instinct he reached to open a valve in his metal helmet that would let the surplus air escape.

Instead of the ordinary stabilizer that balances the craft in mid-air, the pilot has at his right hand a wheel that shifts the relative positions of the entire wings.

THIS is the season when the storage battery service stations are busy. A few months of cold weather have placed the average auto storage battery under a heavy load, and starting troubles have begun. Cold motors require plenty of power to crank them, and unless special precautions are taken the charge in the storage battery gets lower and lower until the car refuses to start.

THE main reason for the introduction of the new X-type sockets, in which the tube prongs are pushed into holes where they make contact with springs pressing against their sides instead of at the tips, is because the tip contact is often the source of scratching and rasping sounds in the loudspeaker.

E. E. SCOTT
FOR the man with a home workshop, the climax of his pleasant labors undoubtedly comes when he builds a home of his own. It is then that he trots out his hobby for a real joy ride and collects the dividends due on his pine or whitewood “stock.” It is then, too, that he finds these dividends amount to something more tangible than the joy of creating and may be cumulative to the extent of as much as ten percent of the cost of his house.

THIS colt is a cross between a rocking-horse and a roller coaster.

But it is a new thrill for the youngsters and is intended for use outside, on sidewalks and porches as it does not perform well on rugs, or, for that matter, on lawns.

HERMAN HJORTH
INLAYING is often regarded by the amateur craftsman as a difficult process. This is because he has never seen how inlaying is done and, therefore, does not realize how comparatively simple and easy the process really is. While inlaying is quite easy to do, it is a process that does not lend itself readily to machine production.

PORCH post boxes have long been a hobby of the writer’s. I have tried to make them; did make them, elaborate ones. But that little spark of artistic feeling always condemned the finished product. At last I found them—the boxes I wanted. They were, however, not the offspring of any of my inventive moments.

BAG punching is enjoyable and healthful, but usually only those who have access to a gymnasium indulge in this exercise. That is partly because the oldfashioned type of punching bag support takes up too much room in the average home and is too noisy.

ASPHALT is a fossil which forms lakes on the island of Trinidad, is found swimming about in the Dead Sea, and is even present in certain limestone formations. Its solubility depends largely upon its origin. Ether will dissolve a small quantity of a greenish oil from asphalt of better quality, and a much larger quantity from poorer grades.

WHEN a duplicate door key is needed or a broken or lost key must be replaced, the handy man usually can file a blank key to fit the lock, if he knows how to go about it. Indeed, it is easy to file keys for the common tumbler locks (Fig. 2), and even make duplicate keys for pin tumbler locks when necessary (Fig. 1).

Brass Center Plates Aid in Assembling Machine Parts

G. A. LUERS
WHEN all the lathes are busy, a rush turning or boring job often can be done on the milling machine, using the regular milling vise for holding the tools. A glazed wheel will not cut properly and is likely to burn the work. When a grinding wheel glazes there is something radically wrong about the way the job is being handled.

MILLING Machine SOMETIMES the set-up for milling machine operations is such that small end mills, drills, or boring tools do not project far enough over the table to reach the work. The extension shown was devised to overcome this difficulty. It has a shank to fit the spindle and a taper hole to take the tools. If the milling machine has holes in the end of the spindle for fastening arbors, a flange should be put on the extension for these screws.
