A New Way of Keeping the Wolf from the Door (Oct, 1932)

A New Way of Keeping the Wolf from the Door

IN THE drought-stricken section of North Dakota, Ed M. Canfield, of Williston, and his wife, Dorotha, keep the wolf away from the door by dragging him in and making him pay the family’s winter expenses. Canfield is one of the West’s best coyote hunters. But, unlike other hunters, he uses an airplane to track down the coyote, or, to be more correct, his wife flies the plane while Dad Canfield handles the shotgun.



That’s exactly what Julium Kovack does with his amazing new formula.

AFTER ten years of painstaking research Florida jewelry-maker Julium Kovack appears to have stumbled upon a method for preserving fish and game by means of three simple chemical injections that petrify the specimen.

they hunt bats

Bats are very interesting animals – and these two scientists are experts at prying out their secrets.

By Clay Perry

THERE are all kinds of hunters, all kinds of hunting grounds—hunters with microscopes, elephant guns, cameras, hunters whose field is the jungle, the stratosphere, the ocean depths—but here’s the story of two hunters in earth’s underworld—American scientists, young, champions both. Their hunting is done in caves. They take their game alive, for the most part, by hand and net. Laboratory specimens they sometimes shoot. The rest of their game—and the numbers mount into the thousands—they shoot only with cameras, and let them go.

Surgeons Save Life of Huge Python (Apr, 1923)

Surgeons Save Life of Huge Python

BY PERFORMING two operations within two weeks—probably the first attempt to apply surgery on such a scale to the treatment of reptiles— surgeons recently saved the life of a valuable python transported from India to Long Beach, Calif.

The python is 29-1/2 feet long, weighs 280 pounds, and is nearly 100 years old.

Did Prehistoric Man Kill Sloths in Old Nevada Cave? (Oct, 1931)

Unless sloths used to be a whole lot quicker (video), I don’t think this would have been much of a fight.

Did Prehistoric Man Kill Sloths in Old Nevada Cave?

Mute evidence of what may have been a war of extermination by prehistoric men against giant animals has been revealed by the Carnegie Institution of Washington, D. C. Bones found by explorers in Gypsum Cave, Nev., a deep, dry cavern 300 feet long with a crystal-encrusted roof, showed that this cave must once have been the home of a great herd of giant ground-sloths.

How to Tame Wild Humming Birds (Oct, 1952)

How to Tame Wild Humming Birds

RALPH J. AYER, a farmer living on a rural route out of Eastonville, Colorado, has a hobby that requires a great deal of patience—that of taming wild humming birds. The humming bird is very suspicious of mankind as a rule, but Mr. Ayer decided to try to trick them into becoming better acquainted with him.




THOSE who are inclined to regard the scissors grinder as a dull sort of fellow, who is content to push a cart with a tinkling bell through the streets, may well

contemplate the picture reproduced herewith, of another sort of scissors grinder. He uses his bicycle, riding it until he has work to do, and then supports the rear wheel in the usual way, and uses the machine as a source of power and as his work-bench, too. A simple attachment runs the emery wheel mounted on the handle bar, and the up-to-date grinder may sit at ease and pedal as he does his work.


I found the 1922 preliminary report on the process along with the 1926 study done on the composition, digestibility and feeding value of the hydrolyzed sawdust.

From the 1926 article: “The method of treatment consists in cooking the sawdust under 120 pounds pressure with dilute sulphuric acid, which converts
a portion of the cellulose and allied substances into sugar. The liquor resulting from the digestion together with the washings from the undigested sawdust residue is neutralized with lime and evaporated to a thick syrup, which is mixed with the dried residue. The product is then ready for feeding. It is a dark brown somewhat powdery meal with a slightly sweet woody odor and a woody flavor.”

Before anyone tries to draw comparisons with “Fresh Horizons” bread from the 70’s, that high fiber bread contained wood pulp and NOT sawdust. And it was banned in Canada.


Making cows eat sawdust, and like it. is the feat of the Forest Products Laboratory, Madison, Wisconsin. A process has developed that converts the fiber of the woody pulp into food for cattle by treatment with heat and chemicals. Its immediate application is seen in utilizing the sawdust that was formerly a useless by-product of lumber camps. Tests indicate that cows and other livestock thrive on the sawdust diet.

Stuffing the Evidence (Sep, 1947)

Stuffing the Evidence

Thore’s no need for a tall talc when you’ve got proof nailed on the wall.

FISHERMEN and hunters have in all ages enjoyed a justifiable pride in their accomplishments. Around this human weakness has grown the art of taxidermy. Among sportsmen, one of the best known of these craftsmen is Fred C. N. Parke, of Bangor, Maine.

Originally, he worked exclusively with game, but in recent years his volume has swung from animals to fish owing to the decrease of animal shooting and the upsurge in the popularity of fishing.

How Pregnancy Tests Work (Mar, 1964)

This is a whole hell of a lot less convenient than “pee on a stick, see if it changes color”. Living in Portland, my first thought was: “But what will the vegan girls do?”. Also, while he is a gynecologist, I’m not really sure I’d trust medical advice from someone who is President of the Metropolitan New York Society of Clinical Hypnosis.

How Pregnancy Tests Work

How doctors decide if a woman is — or is not — pregnant.

by Dr. Leo Wollman, M.D.

The first thing a woman thinks of when her menstrual period is late is: Am I pregnant? Usually there is no way for her to know for certain at this time until her doctor has her take a pregnancy test.

What is a pregnancy test?

Most of them are based on the presence during pregnancy of an increased amount of a substance which stimulates the sex glands— called gonadotropin—in the woman’s blood or urine. The sample is injected in a small animal (usually a rabbit, a mouse, or a frog), and if the animal shows certain changes in its reproductive organs, it means that the woman is pregnant.
