Scientific Explanation of the Mexican Jumping Bean
THE Mexican jumping bean, that playful little legume which many suppose to be nature’s attempt to furnish a concentrated meat and vegetable ration, needs no longer puzzle the uninitiated, for science has laid bare the secrets of its life.
Safe Coop for Shipping Chicks
FORTY-EIGHT brooder chicks up to four weeks old can be shipped 1500 miles with ample food and water provisions in the new inexpensive portable coop shown below. Ridges on the top and sides prevent baggage men from shutting off ventilation when piling the coops.
Undoubtedly someone will accuse me of wanting to nuke dogs now.
These Dogs Are Really “Hot”
Radioactive beagles are pointing the way to better safety devices for workers in atomic energy plants.
A PACK of 300 sad-eyed, floppy eared beagles are serving as canine guinea pigs in an unusual University of Utah project designed to investigate the hazards of industrial radioactivity. Financed by the Atomic Energy Commission and directed by Dr. John Bowers, the studies will show what happens to bone and tissue when radioactive substances are injected into the dogs.
WHEN LIZARDS RULED THE WORLD
These huge reptiles roamed the earth 100,000,000 years ago.
THE LIZARDS that ruled the world some 100,000,000 years ago were quite a sporty bunch, as you can see from the photos on these pages. These huge reptiles are one of the highlights of Warner Brothers’ film called The Animal World.
Oil-Soaked Bricks Lure Lobsters
A NOVEL bait for lobsters has been developed by New England fishermen who, knowing that lobsters hanker for anything having an odor of oil, conceived the idea of soaking some common house bricks in kerosene for 24 hours and then placing the oil-soaked bricks in the bait cabin of the trap. Since the bricks are porous, they absorb quite a lot of kerosene and the oily smell clings thereto for several days.
More lobsters are caught in traps so baited than in those in which mixed bait is used. Due to the fact that the bricks retain their oily odor for several days, the work of baiting the traps is lessened and the expense is not heavy, for a gallon of oil will serve to “oil” a large number of bricks.
Trapper a la car
These professional trappers of predatory animals cover their trap-lines via automobiles.
TO MANY, the name “trapper” conjures up a picture of a romantic figure, clad in a heavy mackinaw and fur cap, living in an isolated cabin near Hudson Bay, tramping over miles of trap-line on snowshoes, and making only rare trips to civilization by means of his dog sledge. This is Jack London’s or James Oliver Cur-wood’s trapper.
Why Men Are Superior to Fish
THE reason why men have better brains than fish and why land animals have evolved so much more rapidly than sea animals is to be found, says the Russian biologist, Dr. M. A. Menzbier, in the ability of men and other land animals to turn their heads from one side to the other.
Most fish never turn their heads sidewise but must turn the whole body if they wish to see something not already visible to one of their eyes. The development by the first air-breathing lung-fish hundreds of millions of years ago of the method of breathing air through the mouth into lungs released these creatures from this rigid, stiff-necked condition and made it possible for their descendants, including mankind, to have flexible necks, mobile heads and both eyes pointing to the front. All of these changes aided greatly to exercise the brain and improve it.
ROCKING-HORSE TRAINS BRITISH RIDERS
Mounted on rocking-horses, recruits of the British cavalry are now receiving preliminary training in horsemanship. At the Army Equestrian School, at Weedon, England, the wooden horses were recently installed to give rookies the feel of the saddle and practice in mounting and dismounting before they tackle the spirited animals stabled at the school. In advanced horsemanship, the wooden horses are also employed in teaching acrobatics and trick riding. They are said to be especially useful in helping riders acquire the right balance when a horse takes a hurdle. Dismounting from one of the rocking-horses, by means of the spectacular neck-roll, is being demonstrated in the photograph by the chief instructor.
It’s been a long time since writers who mentioned a penguin had to explain what one was.
Penguins Move Enmasse on South Sea Isle to Guard Eggs
COVERING every available piece of land on a small island in the South seas, hundreds of thousands of penguins, strange aquatic birds shown above, tend their eggs during the period of incubation. The birds have a general elliptical shape with a neck of moderate length. Their heads are small with a comparatively long bill. They have no quills in their wings, which are useless for flight. However, their flippers move freely from the shoulder joint, making good paddles for swimming.
Double-Headed, Four-Eyed Calf Eats with Both Mouths
MOST double-headed calves are stuffed; but on the farm of Edd Ellis, at Arkansas City, Kans., is one so much alive that it eats with both its mouths! In fact, the animal seems to find that two, heads are fully as useful as one. The body of the calf is normal, but there are two complete heads, with two noses, two mouths, and four eyes.
