IN a recent tryout of the novel type of plane shown at the left, which its inventors, Wendel Wobido and Stephen Nagel, of Berlin, call the "Comet'' plane, and which was designed to navigate air, land and sea, navigated land and sea all right, but when it came to going up into the air the darned thing balked and refused to depart from safe old Terra Firma, or rather, in this case, since they tried to take off from the water, good old aqua firma.
Developments in the mechanization of the army is the installation of radios in tanks for the transmission and receipt of orders. Control of tanks in action, since they were first introduced by the British during the World war, has been at once an important and difficult task, hitherto performed by officers who walked beside the tank and signalled with flags—a duty both dangerous and unsatisfactory.

Airplane and Automobile in One THERE is no telling what aviation may come to. In the future we may see such contraptions as shown above flying about.
WHAT is most certainly one of the strangest airplanes ever built is shown on this page and on this month's cover of Modern Mechanics and Inventions. The plane, which its designer, Paul Maiwurm of San Diego, California, has ailed the Fly worm, will have no propellers to pull it through the air
These three boys teamed up in an attempt to keep the bicycle moving all summer. The credit here should go to the bike instead of the boys. Shipwreck Kelly, world's champion flagpole sitter, has sat on about every pole except the North and South, and he may tackle these sometime.
A COMPLETE executive office and comfortable living quarters have been combined into a single motor bus body by Fred D. Martin, an executive of a linen supply firm in the Southwest. He uses the vehicle to visit the branches of the company in which he is interested, thus being able to conduct routine business while en route.
THRILLS are commonplace for William H. McAvoy, test pilot for the National Advisory Committee for Aeronautics at Langley Field, Va. But "Daredevil Bill" probably will not forget in a hurry the events of the other day when he was called upon to test the sensational single-motored bombing plane just developed by Glenn L. Martin.
Gas Sounds Cable Damage Alarm THE Pacific Telegraph and Telephone company has recently put into use a method to locate cable troubles which uses gas as the detecting agency.

by Daniel L. Hazard Famous Earthquake Expert WILL the learned men of science, with all their vaunted weapons, ever be able to do anything about the earthquake, the world's most mysterious and devastating convulsion of nature? Of course, one might as well try to stop a quake as to control the arrival of hurricanes, typhoons and tornadoes. But there is hope for the world in the fact that the newest scientific methods follow the sensible plan of studying the natural phenomenon with greatest care before attempting to solve its problems. These methods are now being followed by the seismology division of the U. S. Coast & Geodetic Survey.
The FREAK of the MONTH~No. 1 The oddest contraption which has been brought to our attention this month is the Outboard Ski-Plane now being constructed by C. T. Elle, of Chicago. The idea is that when the boat gets up speed the front of the skis will be raised, causing the boat to come to [...]

by ALFRED ALBELLI All the resources of modern science and invention are employed by the clever card sharp who sets out to fleece a wealthy victim. You yourself, if you play cards, are fair game for a crooked player unless you are forewarned of his methods. In this article Mr. Albelli exposes the clever methods which enable the crooked gambler to cheat without his victim being aware of what is going on. ONE night last August four men sat down to a congenial game of stud poker in a Saratoga hotel suite, where one pays fifty dollars for a night's lodging with benefit of bath.

By Sam Brown Here are some amusing parlor tricks, which require no elaborate equipment, for entertaining your friends. ABOUT the best trick ever performed with a rubber band is the one concerning the back of the school teacher's neck and a juicy wad of paper. But there are others . . . For something absurdly simpleâ€”or is it? â€”try this one: Take a stout rubber band and snap it over your fingers and thumb at the first joint. The idea is: Can you, using this one hand only, work the rubber band down to your wrist? Try it! Dollars to doughnuts you'll get the most desperate, useless feeling when you get the rubber band about half-way down and find that despite all your finger waggling it will go no further than the middle of your palm.
By WalterE. Burton Here's a simplified Toepler-Holtz static machine for generating high-voltage electric sparks. By experimenting with it you can learn something about the nature of electrical currents. IF YOU are interested in learning the nature of that mysterious and invisible force known as electricity, there is no better means of studying it than by experimenting with this inexpensive and easily made static machine. This is not a machine, mind you, which makes that awful noise in your radio receiver, but a device which generates high voltage electric sparks which are quite harmless, but with which you can have barrels of fun. It is of the Toepler-Holtz type which is used in most school physics labs to demonstrate the strange things that electricity can be made to do.
Giant Typewriter Weighs 14 Tons A MAMMOTH typewriterâ€”an exact duplicate of the smaller machineâ€”standing eighteen feet high and weighing fourteen tons was recently placed on display in Atlantic City’s auditorium convention hall.

by RUBE GOLDBERG Famous Cartoonist as told to Alfred Albelli Four hundred inventions a year, all of them of exceedingly "nutty" brand, qualify Rube Goldberg, the famous cartoonist, as one of the country's most prolific and best paid inventors. The fact that his inventions never get beyond the pen and ink stage doesn't prevent him from "cleaning up" from them. "How did you get that way? How do you do it? How do you get away with it? How do you get them to fall for your stuff? How are you, anyway?" There you have the barrage of questions which are popped at me every day of my life, including days when the game is called on account of rain. It's a good thing a humorous cartoonist has got a sense of humor. Or I might borrow from that jolly English expression and say, "It's fortunate my humor is not bad."
Edited by THEODORE ALLEN Experimenting with electricity is a most fascinating and instructive pastime.

Future Sources of Power, Described by WILLIAM J. HARRIS When coal mines are exhausted, where is industry to obtain the power to keep its wheels turning? What sources of power are now lying dormant, waiting for some engineering genius to harness them? This important subject, of ever-present interest to scientist and layman, is fascinatingly discussed in this authoritative article. DR. Georges Claude, brilliant French inventor, recently expended a million dollars and, after two unsuccessful attempts, succeeded in launching a mile long steel lube, some six feet in diameter, in the waters of the sea off Matanzas, Cuba. And most of the world is still wondering what he is trying to do.

By Jay Earle Miller Fantastic as it may sound, it is a scientific possibility that in some distant age man will disappear from the earth, his food supply ravaged by insect hordes who remain to dominate the world. Mr. Miller's article is a fascinating discussion of a subject which has been made increasingly important by the many existing crop-destroying pests. A WORLD ruled by giant insects, with the last remnants of the human race as slaves is one of the favorite devices of one school of fiction writers. Fantastic? Not at all. Thoughtful scientists recognize that as one of the possible endings for our civilization. In fact, all past history indicates that when, and if, the present civilization comes to an end, it will die because of an unsolved food problem, and that insects will be a contributing factor, and hence may be the survivors.

by JAMES NEVIN MILLER The gangster is commonly thought of as a product of modern civilization, but in reality he has existed since the world began among all forms of life. In this article you will read of how the predatory animals are preying upon their fellow creatures and encroaching upon the domain claimed by man. How the forces of the United States government work to stamp out the criminals of the animal world constitutes a story as gripping as any detective yarn. "BRING him in, dead or alive!" This square-jawed sentence sounds like parting words of advice to a posse of deputy sheriffs. But in this case it does not apply to man trailers but to animal hunters. It is the slogan of the super-sleuths of Uncle Sam, now engaged in a relentless battle against a vast animal underworld with headquarters in the great Western stock country.
