War clouds brewing in the Pacific point to the day when America may become involved in battle with Japan. Nobody is eager for such a war, but if it ever comes the result will be decided by war machines built by American and Japanese mechanics—two fundamentally different types of genius. Read this keen analysis from the pen of a noted naval expert. by LIEUT. JOHN EDWIN HOGG U. S. Naval Reserve AS THESE lines are written international diplomats are gathered together at Geneva. They are assembled at the world's first general disarmament conference, ostensibly to work out a plan for preventing armed conflicts between nations. The God of War looks down from a neighboring planet upon a world bristling with every possible device for killing the greatest number of people with the least effort. And in Shanghai war rages between Japanese and Chinese troops.

IF YOU purchase, borrow, or receive as a present a motion picture camera, you will find the mere process of photographing everything in sight thrilling enough for the first half-dozen reels. Then you will look about for new fields to conquer. Perhaps you will undertake the making of your own dramas or comedies—movies with a plot or at least a basic theme.
THE odd plane described here is just another manifestation of the wing-flapping idea which has cropped up periodically ever since man first considered the conquest of the air. There is a certain brand of inventor obsessed with the idea that the only satisfactory way to achieve flight is by a literal application of bird-flight principles. To this class of inventor all present day aircraft appear completely unsatisfactory particularly in their use of airscrews rather than wing beats as a means of propulsion.
Initials Engraved on Fingernail MONOGRAMED fingernails is the latest fashion in fingernail adornment. The initial is put on by an engraving sten-cil filled with warm wax.
