Jet Noises Tried Out on Guinea Pigs (Feb, 1951)

Jet Noises Tried Out on Guinea Pigs

Jet engines make a lot of noise—enough to pain or perhaps harm your ears. To find out more about the effect of very loud noise on human ears, Air Force scientists at the Wright-Patterson Base are learning what it does to guinea pigs’ ears. The anesthetized animals (below) are placed in a soundproof room equipped with sound generators. Those are not earphones Dr. H. E. von Gierke is wearing, but muffs to protect his ears.

Farms of Future to Have Giant Stock (Aug, 1935)

Farms of Future to Have Giant Stock

WHAT will future ages do for food?

Some have suggested that the chemists will set up huge machines, to turn out proteins, starches, sugars, fats and vitamins, which will be taken in suitable “tabloid” doses daily by the population; that instead of farms, we will have only great chemical works, full of vats and tanks, while the outdoors is used for parking purposes exclusively.

Motor Ambulance Carries First Aid to Injured Dogs (Mar, 1922)

Motor Ambulance Carries First Aid to Injured Dogs

DOGS injured by autos on the roads near London, England, now are cared for by a motor ambulance. A veterinary gives first aid on the spot, and if there is hope of saving the life of the pet, it is placed on a thick bed of straw and carried to a kennel for further treatment.

The ambulance is ready for service day and night, and is summoned by telephone. All the farmers living near the roads in the district outside of London covered by this service notify headquarters as soon as they are aware that an accident has taken place, and the cyclecar immediately starts.

Fido Gets Motorcycle Side-Car (Aug, 1931)

Fido Gets Motorcycle Side-Car
BEFORE the bicycle went modern and acquired a motor, Fido could get his Sunday airing with the rest of the family under his own power. He can never hope, however, to keep up with the speedy motorcycle, so one English dog lover has installed a miniature sidecar for Fido’s private use. The tiny sidecar is equipped with its own private celluloid windshield which folds back as shown in the photograph below, protecting the dog from the elements.

Underwater Gallery for Aquarium (Aug, 1936)

Underwater Gallery for Aquarium

SHARKS are always intriguing to the curiosity—more so than lions; for you can less frequently get a good look at a shark. A professional shark hunter is now promoting plans for an open-water aquarium with, not tanks, but pens; and floating steel compartments from whose windows thrill seekers may watch the demons of the deep. The idea, as distinguished from its accomplishment, is very old; a medieval picture shows Alexander the Great in a (fabulous) submarine observatory.

Camera Trap Catches Unusual Poses of Smaller Forms of Wild Life (Jan, 1933)

Camera Trap Catches Unusual Poses of Smaller Forms of Wild Life

AN ORDINARY mouse trap and a few feet of 1/2″ x 1-1/4″ stock are all the parts required to make this automatic shutter release for your box camera. The device, which should be painted green, is unique in catching unusual poses of small forms of wild life.

At one end of the 51-in. base, construct a mount for the camera. The rear of the mount is 5-3/4″ and the front is 5-1/2″ to allow the lens to point down into the camera field. Screw the trap to the base of the device directly below the lens. A short length of wire connects the camera lever to the trap spring. Another length runs from the trigger through wire screw-eyes in the base to the opposite end where a nut or morsel of food is fastened as bait.

Mother Hen Eats Dye, Chicks Hatch Out Freakish Colors (Jan, 1933)

Mother Hen Eats Dye, Chicks Hatch Out Freakish Colors

THE chickens seen in the photo at the left may look just like any brood of infant barnyard fowl but that is because Modern Mechanix couldn’t print them in colors. In the flesh, however, they are a deep pink in hue with bills and toe nails a resplendent rose color.

The chicks were produced during experiments in which the mother was fed red dye. Further experiments are under way with other dyes and soon purple and green hens may be as common as white and brown ones now. The chickens otherwise are normal in every respect.

Combination Cat, Fish Globe Affords Unique Spectacle (Jan, 1933)

Combination Cat, Fish Globe Affords Unique Spectacle

HOW to exhibit prize winning kittens and butterfly goldfish to the best advantage was the problem of Mrs. J. T. Mopham, a cat and fish fancier of Los Angeles. She left the task up to a large glass company of her town who proceeded to turn out the specially built fish globe with an inside compartment for kittens.

The result, as illustrated in the photo at the left, was really startling. The outside compartment, filled with water, houses the goldfish with the kittens occupying the special bowl inside. Onlookers are bewildered when they apparently see the kittens and goldfish living in peace and harmony in the same bowl of water.

Animal Lending Library (Aug, 1953)

Animal Lending Library

KIDS today get all the breaks. Now they’ve even got a lending library in Sacramento, Calif., where Junior can borrow almost anything from a snake to a skunk (deodorized, natch) for a temporary playmate.

At this novel pet-dispenser, instead of taking home a book of stories about Reddy the Fox or Hoppy the Rabbit, boys and girls can borrow the real thing. Only stipulation is that the kids must be at least seven years old and must guarantee to give the pet first-class care and affection.

The library only stocks “light” reading matter, though. No elephants, for instance.


I’m sure the elk would be quite honored if there were any left.


Elk antlers have been gathered and formed into an unusual monument in Yellowstone National Park. The monument, which is twelve feet high, marks the place where thousands of elk once roamed, before the large herds were wiped out by hunters. Rangers in the park are responsible for this tribute to the departed elk.
