Balbo Plans Daring Non-Stop World Flight THE first actual world flight of 25,000 miles in two days without a landing is said to be under consideration by Gen. Italo Balbo. Four seaplanes, designed for flying eight miles above the earth, would accomplish the feat by refueling in four dirigibles, spaced at 6,250-mile intervals. One dirigible […]
AN ENEMY so tiny that it cannot be detected by the most powerful microscope is giving medical science one of the greatest battles of its historic career. And thus far science can not claim the victory. The enemy is the mysterious transmission agency responsible for the spread of the strange malady of sleeping sickness or "encephalitis" because it attacks the "encephalon," or brain. The epidemic in St. Louis, Mo., and its suburbs is the largest outbreak the country has ever known.
HIGH pitched whistles to designate boundaries of an airport make it possible for a pilot to make a blind landing, recent experiments have shown. The newly designed whistles, called sonic marker beacons, send out fan shaped beams of sound by means of which the aviator can determine definitely the length of the airfield.
COLLAPSIBLE armored shields to protect the bodies of police in gun battles have been invented to aid Uncle Sam in his war on crime. The shields were designed following the slaying of four officers in front of the Union station in Kansas City, Missouri. The collapsible armor permits free movement of the body. The shield is made in three sections, the two end sections hinging to the center body piece. At the top is an opening fitted with bullet-proof glass through which the officer can see ahead.
Tall Periscope Aids Golfers A NOVEL “skyscraper” periscope shows golfers the blind fairway at the third hole at the Aberoovey golf course in Wales. The unusual periscope is 30 feet tall.

AN ENGINE run only by a single rubber band—does it have possibilities of perpetual motion? Many who saw it on exhibit at the Hall of Science in Chicago's Century of Progress Exposition believe it has. The engine, shown on the left, obtains its energy from heat directed on the rubber band. Many persons visioned the probability of substituting solar heat for the electrical heaters used in the exhibit. However, perpetual motion is an impossibility as the machine would run only during life of band.

by RALPH SPENCER Customs Bureau Men, perplexed by the flood of narcotics, precious stones and undesirable aliens pouring across our borders, have now traced the contraband goods to their sources—"sky smugglers." How Uncle Sam's new aerial border patrolmen hunt down these outlaws with ingenious aerial strategy is told in this story of gripping aeronautical adventure. FIVE thousand feet above the arid Texas-Mexican border an airplane speeds on a secret, illicit mission. Traveling well over 150 miles per hour the craft maintains its speed until about three miles west of Poteet, Texas.
NOVICES can pilot airplanes without any training on a new amusement park device. The untrained pilot can dive, climb, and hank at will. He is limited, however, to a small circular course by the arms of the machine which holds several planes. The airplanes are standard ships and are controlled by regulation "joy sticks." Each plane is run by its own three horsepower motor.

With present microscopes only germs that have reached maturity could be seen. With the new powerful 21 phase microscope it will be possible to study and photograph germs in […]
From a battered flivver E. L. Cord has built an empire of automobiles, airplanes, ships and railroads. Here is the story of the amazing career of this young mechanic who became a financial genius. A youth of 20 proudly drove a battered flivver out of a dealer's yard in Los Angeles. The engine wheezed and died. The youth spun the crank futilely. Then he pushed the car to an incline, and it rolled downward just as he got a precarious footing on the running board. He tumbled into the seat and grabbed the wheel. The motor awoke and the car chugged on. Three weeks later the youth appeared in the yard—behind the wheel of a glisteningly maroon "speedster."

FOR economic and technical reasons a mixture of alcohol and gasoline for automobile fuel is being recommended by farm relief advocates. Use of the fuel by motorists would consume 680,000,000 bushels of corn a year, greatly reducing the crop surplus, it is said. The gasoline would be diluted with 10 per cent of alcohol. It is claimed the fuel results in greater power at considerably less cost.
