A FOUR BLADED SCISSORS that may be adjusted to cut ribbons in widths ranging from a quarter inch to two inches is supplying the need of dressmakers for such an article. It is shown in action in upper right. SHARP FORK TINES soon become dull. As a result a sharpener has been invented to maintain kitchen forks in perfect shape. As shown in upper left, the sharpener contains a cone of file edge ribs.
ARMED only with a forked stick, a hunter walked warily through the squat bushes of the San Fernando valley in Southern California the other day. Suddenly he froze in his tracks, warned by a series of rattles that hidden danger lay waiting. He advanced slowly, saw a Pacific rattle snake lying coiled and ready to strike. With the skill acquired from many such hunts, he pressed the stick down over the snake's neck, stuffed the reptile into a box, and hastened back to his Hollywood studio. There John Schleisser, famed naturalist-taxidermistâ€”for it was he who captured the deadly reptileâ€”chloroformed the rattler. A few minutes later he could be seen taking exact measurements by making a plaster cast of the body. Then he skinned the rattler, made a mannikin of papier mache duplicating the late deceased, and a few days later fitted the skin, perfectly tanned, back over the artificial body.

"It's easy to take a snapshot," as 500,000,000 pictures a year will testify. But behind the click of the lens there lies a story of high speed chemistry fascinating in its scope. The early amateur photographer carried a bulky apparatus in a portable, tent-shaped darkroom into which he plunged for a freshly-sensitized glass plate every time he wished to take a picture. Today's amateur, exposing some 500,000,000 snapshots yearly, has at his command a vast array of lightning-speed emulsions in convenient sizes and shapes, which are ready for instant use.

Pulsating through the skies in much the same manner as employed by the jellyfish in propelling itself through water, a weird parachute artillery spotter is expected by its inventor, John A. Domenjoz of New York City, to supersede the ordinary kite-balloon in observation work during war. Greater maneuverability with resultant greater safety for the pilot, economy, and the elimination of ground crews are among the advantages claimed for this type of craft.

Black gold, precious underground liquid, is food for the modern war machine. Deprived of it, a nation's military campaign is threatened with failure. Will oil become an instrument to enforce peace or to cause war? WITHIN the last few decades, oil has changed from an almost unknown and unnecessary commodity to one of the world's most vitally needed materials. Oil, unlike nitroglycerin, has always been an innocent, viscous fluid used for lubrication and fuel. But harmless petroleum, like Dr. Jekyll, has undergone a startling transformation. Oil may yet be the means whereby the flaming torch of war is carried across the world.
