UNLESS a tramp poodle dog is lucky as a hitch-hiker he needs boots for a cross-country hike. C. C. Maupin, of Philadelphia, left New York on a hike to Los Angeles. At West Newton, Pennsylvania, he was adopted by the poodle shown at the left and they continued the hike together. About 500 miles on the way, somewhere in Indiana, the poodle had worn off its claws, making further walking impossible.
By WALTER E. BURTON Distorted photographs giving the bizarre effect one obtains on looking into a curved mirror provide a novel form of fun-making. The methods of producing such photos described below can be used by any amateur photographer. DID you ever see a funnygraph? Or perhaps you would prefer to call it a "phoneygraph." Anyway, a funnygraph is an ideal means of proving, photographically, how your friends do not look. It is simply a photographic enlargement that has been purposely distorted by any of a dozen or more methods so that the normal features are no longer normal.

Mind ticklers in "Edison's brain derby" cover wide field of specific, catchy and general problems, answered most satisfactorily by Wilbur B. Huston, 16-year-old Seattle boy. Purdue scientist said they were easy enough for any high school boy or girl who had studied elementary physics. FORTY-NINE boys, hand picked from among pupils in high schools through-cut the country, spent five hours in answering a questionnaire drawn up by Thomas Alva Edison, the famous inventor—a set of questions which would prove sticklers for many of their elders. The examination represents a searching test, not only of the practical education of the applicants for the scholarship offered by Edison, but also of their ideals, character, resourcefulness and practical understanding of usual conditions and general information. The winner of the brain derby, Wilbur B. Huston, is the 16-year-old son of Bishop S. Arthur Huston, of Seattle. The boy chose to go to the Massachusetts Institute of Technology for the four-year scholarship he won. His progress will be closely watched by Mr. Edison who is on the lookout for genius to help carry on his work.
They should have had another label on the picture, pointing at her head with the text “Woman”.

By 1st LIEUT. W. C. FARNUM Air Corps, U. S. Army Aviation history records only one instance of a balloon looping the loop. Lieut, Farnum tells here the story of his aerial somersaults. WATCHING an airplane loop the loop always reminds me of a morning 12 years ago when I was a flying cadet at Fort Omaha in the balloon service, waiting for my commission and instructing student officers in balloon observation. This particular morning I was to ascend 3,000 feet and instruct a student in observation. I checked the balloon and gave the order.
WILL science ever be able to take photographs of the spectra of the sun and other stars with cameras far outside the range of the earth's atmosphere? Speculation on this possibility has been renewed by the recent experiments of Prof. Robert H. Goddard, of Worcester, Mass., in launching rockets of his own design powered with a secret liquid propellant which he invented. Contrary to popular belief, Prof. Goddard has no intention of occupying one of his rockets on a fantastic journey to the moon. As pointed out by Dr. C. G. Abbott, secretary of the Smithsonian Institute, a close friend of Professor Goddard, the professor's experiments are directed toward a scientific exploration of the upper heavens at distances now far beyond the reach of man.
Almost all of the 40,000 inventions patented each year by Uncle Sam are workable devicesâ€”but as to being practical, that's something else again. The inventions pictured on these pages, all of them taken from patent office records, are somewhat funnier but no less impractical than a large number of devices which their inventors see fit to protect with a patent. Read 'em and weep!

STEADY nerves and a keen eye are required to accomplish this trick shown at left. This young woman is poking a four-foot stick at a toy balloon while driving her car 50 m.p.h. past the pole on which the balloon is mounted. The stick is pointed at one end with a sharp piece of metal so that when a "strike" is made score can be kept by counting the number of balloons broken.

By R. D. ADAMS The mechanic who made Houdini's Trick Magic Apparatus Harry Houdini, Prince of Magicians, carried with him to the grave the secrets of his extraordinary feats of illusion. Only one man, the artisan who made his magic apparatus, knows the working secrets of Houdini's most mystifying stunts. That man, Mr. R. D. Adams, continues here his fascinating expose of the master magician's methods. HOUDINI was a master at the art of obtaining free publicity. No performer ever put on as many free shows for the purpose of breaking into print, and for that matter, few if any, were ever as liberal as he in the matter of entertaining lodges and other groups without charge. Many times he risked death in his publicity seeking stunts.

ONLY one out of a thousand residents of Chicago realizes that his city has an extensive subway system. No people ride in this subway, however, except the operators of the trains, for it is purely a freight subway. The photo above gives some idea of how the loop district is undermined by a network of tunnels; practically every department store and large business establishment has underground connections with the freight subway.
