Phonograph Records Teach Parrots to Talk in One Week
PETER JENSEN, a veteran bird trainer at the Luna Park zoo, Los Angeles, has simplified the task of teaching parrots to talk. He holds “classes” twice a day, his classes usually consisting of four or five birds seated on a perch that has a phonograph with a loud speaker at one end. His records are specially made and reproduce the usual phrases such as “pretty poll,” “hello polly,” etc.
When he turns the machine on the “pupils” soon become interested. After an hour of this instruction each day for six days, even the dumbest bird begins his imitations. They are then graduated to the whistling class and later to grand opera.
GRENADE FIRED FROM A RIFLE
By WILLIAM T. WALSH
PEKIN was fortified; the Boxers held the gates. Outside the walls of the city the allied legions clamored for admission, knowing that, within, the members of the foreign legations, fortified, in their turn, against the Chinese, were awaiting with breathless anxiety the arrival of the friendly armies.
But the gates could not be rushed.
Suddenly, three or four soldiers, in the Japanese uniform, dashed forward, up to the gates.
A shower of bullets greeted them. They fell. But their work was done. The hand grenades which they had hurled against the gates had exploded, battering them down.
Pekin had fallen.
Underground Nests for War Airplanes
THE next war, all agree, will be a war in the air; and the advantage will be with the force striking the first blow. Obviously, the attack will be made on the fixed air bases of the other army, since that will inflict most damage from a military point of view. An airplane on the ground is quite helpless; and its hangars and shops are vulnerable. During the late war, battleships were kept at their bases to protect them while not engaged in battle with similar foes; but the ship always floats, while the airplane must spend most of its time grounded.
Liquid Rocket, Germany’s ME 163B fighter, was only a rumor when MI commissioned their staff artists to do drawing below that appeared in May, 1945, issue. Photo of real plane was recently released.

This Gun Replies to “Hands Up!” With Bullets
IN THESE days of flying bullets and indiscriminate hold ups, the well dressed Chicagoan should wear a breast machine gun and armor vest such as is shown in the photo to the left. Samuel Schwarz recently invented these two pieces of equipment for every day wear. Instead of merely throwing up the hands when threatened by a hold up man the wearer can spray a stream of lead bullets in his face.
The strings that control the machine gun are held between the first and second finger of each hand. As the operator raises his hands and faces toward the gunman he can pull the string that controls the aim of the piece. When he has proper aim the other hand will pull the trigger. (more…)
Why Don’t We Have Moving Sidewalks for City Shopping
Conveyor-belt transportation would beautify our streets, reduce noise and help shoppers.

IMAGINE New York’s famous Fifth Avenue devoid of all wheeled traffic.
No taxis, busses or private automobiles, alternately jamming up at street corners and darting ahead at the change of lights. No grinding gears, roaring motors or noxious exhaust fumes. No swarms of nervous pedestrians scurrying back and forth at dangerous intersections. Imagine, instead, a leafy-mall extending down the avenue’s center, green with trees and bushes, brightened with flowers and flanked by a continuous stream of comfortable public cars, flowing smoothly along on silent, rubber belts. In them, milady sits and window-shops at a leisurely pace, hopping on and off at any point she desires. Imagine, too, a pair of subsidiary moving sidewalks with safe, convenient entrances and exits, upon which the pedestrian may ride along at a normal walking pace or gain easy access to the faster-moving cars.
