An Improved Squirrel House
Most children enjoy having pets such as rabbits and squirrels. A house that will accommodate several squirrels, and will permit them to climb a tree without danger of escape, has been found to be a great improvement upon the small wooden houses generally used. The main house should be about ft. square, with a roof slanting down from the front, and supported on posts 3 ft. high. The front side should face the south; it should be as open as possible, and covered with 1-in. poultry mesh.

How Science Has Aided National Game
Much of Improvement in Baseball Is Attributed to Evolution and Steady Progress of Mechanics and Invention WHEN Babe Ruth hits three home runs in one game or the home team cracks out a barrage of base hits to score seven or eight times in one inning, it does not necessarily mean that long-distance hitting in modern baseball comes from superiority of today's players over those of years past.

Flood-Lights Revealing Beauties of Night
More than Twenty Millions of Dollars Spent in Year to Illuminate Outside of Nation's Buildings FROM the time primitive man stumbled about in the darkness with a torch to the modern electric age, human ingenuity, in banishing night by artificial illumination, has developed until today it has reached a brilliant climax in the art of floodlighting. Assembled in bat-teries a n d focused on towers, monuments and lofty skyscrapers, great masses of electric lights serve as an aid to advertising and to emphasize architectural beauty. Last year, it is estimated that nearly $20,000,000 were spent in the United States alone for flood-lighting equipment.

Reading Thoughts by Radio and Inventor Forecasts Private Radio Systems
Can thoughts be read by radio? "Madam Radora" seems to prove that they can. Madam is not a human being, but a life-size automaton shown at the Permanent Radio Fair in New York. Her "thoughts" and movements are controlled entirely by wireless; no wires of any kind are attached to the table whereon she rests, and a liberal reward is promised the person who can prove that this is not true.

Water Veil Guards Walls of Skyscraper
CONNECTED to powerful pumps, a network of 291 sprinklers on the outside of the new Union Central Life Insurance company's building in Cincinnati, Ohio, has been installed to bathe the structure's upper stories in a protecting curtain of water in case of a severe fire in the neighborhood. The sprinklers are similar to those used in interiors, but operate only when the pumps are started.

You'll wonder how Topkis can be sold for a dollar
EVEN if you had never heard of Topkis you'd be likely to choose it among any group of athletic union suits. You'd see, at the first glance, that Topkis has superior quality. And if you didn't know that the price of Topkis is One Dollar, you'd willingly pay twice that much—because even then you'd recognize Topkis as unusual value.

A Seesaw Merry-Go-Round
By HARRY D. TIEMANN A LOT of fun can be had with the teeter-totter merry-go-round shown in the illustration, and any boy can make it who is at all handy with carpentry tools. If built substantially it will amuse the youngsters, big and little, for years. It will go up and down like a seesaw and spin around like a top until the passengers are dizzy.

Power's Toll of Life and Limb Cut Down
Safety Is Sought for Mankind through Science, First in Industry, Today on the Streets, and Tomorrow in the Home By LEWIS A. DeBOIS President, The National Safety Council WE are today riding the crest of what is one of the most remarkable waves of moral progress that has ever swept a country. The world has become mechanical. "Harnessing Niagara" was an achievement. Conveying its force to great distances was an accomplishment. But to make Niagara free itself into little cubes in the millionaire's kitchen, brown the buckwheat cakes on the foreman's breakfast table, and drive the sewing machine in the third floor back, transcends any of Aladdin's mythical efforts.

SUN'S RAYS ARE HARNESSED IN SOLAR FURNACE
ARCHIMEDES, famous mathematician, is said to have set fire to the fleet of the Roman emperor, Marcellus, by the use of a series of concave mirrors concentrating the sun's rays upon the fleet. John Ericsson, the designer of the Monitor, of civil war fame, constructed several engines having boilers provided with mechanical devices for effecting the necessary concentration of solar rays which, when collected from 100 square feet of surface, effected the evaporation of 489 cubic inches of water per hour, more than equivalent to one horsepower. This is, however, but a small proportion of the potential energy actually developed by solar heat hourly received upon an area of this size.

Perils Faced in Around-World Flight
Army Fliers to Cross Twenty-Two Countries in Journey that Will Cover Thirty-Nine Thousand Miles UNDER the imaginative pen of Jules Verne, Phineas Fogg went entirely around the world in eighty days, using boats, trains, elephants and even a sail-equipped sled. On the home stretch he burned' the furnishings of his ship for fuel. But these difficulties pale into insignificance when compared with the hazards of the feat proposed by the United States army—a round-the-world flight by a fleet of airplanes, American designed and built throughout. "The United States," said Maj. Gen. Mason E. Patrick, chief of the air service, "has the distinction of holding every air record of value, including speed, altitude, endurance and distance, and now has conceived a project rivaling in importance the circumnavigation of the globe by Magellan.

Rubber "Actors" Lend Realism to Movies
Comic, Educational and Scientific Pictures Are Worked Out on Miniature Stage with Animated Figures BY means of a series of ingenious inventions and most painstaking study of anatomy and sculpture, a Los Angeles producer has created a type of animated miniature figures which opens up most interesting fields in the realm of educational and scientific motion pictures. As in the case of the use of all miniature figures, the process of making motion pictures of this inventor's figures is a laborious one, each exposure on the film necessitating a re-posing of the "actors." In producing 500 feet as much as four months is required to set up the various scenes and make the hundreds of poses. The work is not unlike that of the maker of animated cartoons who has to make a new sketch for each exposure in the film.

Smoker's Teeth Bleached White New Safe Way
No need for dull, yellow, tobacco-stained teeth now. For a new safe treatment—Bleachodent Combination—bleaches away stains, and makes teeth flashing white—often in just three minutes! Treatment consists of a marvelous liquid, which curdles and softens the stains—and a new kind of paste which gently removes the softened stains and presents the formation of new stains. Safe and harmless, as its mild ingredients are especially combined to act only on surface stains —not on the enamel itself.

PHONE CALLS ARE ANSWERED BY MACHINE
For the convenience of telephone users, an instrument has been devised to take messages and answer calls received when the owner is absent. It consists of a small cabinet containing records similar to those used in dictating or talking machines. If the person is not at home when the phone rings, the instrument repeats a message which has been dictated to it, stating that Mr. So-and-So is out and will the caller speak his message, or any other greeting the owner wishes to give.
