ODDITIES OF LIFE
SCISSORS GRINDING UP TO DATE
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.
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.”
COWS EAT SAWDUST AND THRIVE ON STRANGE DIET
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.
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.
Want Trotting Speed? Try a Moose Team!
Albert Vallancourt, French – Canadian woodsman, has the fastest pair of trotters in his neighborhood— a team of moose which he raised from babyhood at his farm near Sudbury, Ont. Vallancourt insists his team can beat any harness racing records made by horses anywhere. He acquired one of his strange pets when he rescued it from a bear when it was a baby. The other was given to him.
Milking Cows From a Swivel Chair
You can just sit back and let the cows do most of the work in this modern unit.
THE dream of farming by push-button came a whole lot closer to reality this year when the Hervey Research Development Corp. of Geneva, Ill., put on the market its amazingly efficient pre-packaged dairy plant which enables one person to wash, milk and feed 30 cows an hour without even stirring from a comfortable foam-rubber-cushioned swivel chair.
Sitting at ease in the center of the milking room, the operator pulls a cord to open the barn door, twists a crank to measure out feed for each cow, then tugs at another cord to let Bossy go back to pasture. Automatic milkers pipe the Grade A to a stainless steel cooling tank.
Copied live or more times lifeline. ordinary insects are earful, fantastic creatures.
BY ALICE GRAY
Senior Technician, Department of Insects and Spiders, American Museum of Natural History AMONG the most startling exhibits in a museum of natural history are enlarged models of small or microscopic creatures which, though always with us, commonly pass unnoticed or unseen. A housefly as big as a house-cat is a terrifying object, with a weird blank face like the mask of a Martian monster, and an uncouth coat of spines. A flea, made large enough to serve six at dinner, stands revealed as most admirably streamlined, and thus enabled to slip unimpeded between hairs.
Chopper Checkup At the Zoo
DESPITE the wonderful pain-killing techniques developed recently in the field of dentistry, most people are still frightened to death by the very thought of having their teeth checked. One dentist, however, who is usually more wary of his patients than they are of him is Dr. C. P. Gandal of New York’s Bronx Zoo.
Well that’s a useful article…
ELEPHANT DISPLACES LION AS KING OF BEASTS
LIONS have been enjoying the title of “King of Beasts” which really belongs to the elephant, according to Harry C. Ostrander, naturalist. The elephant does not
Possess the regal bearing of the lion, but he can think faster and has a remarkable memory, as witness the truism of the showmen, “an elephant never forgets an injury.”
George P. Meade – SUGAR MAGNATE COLLECTS SNAKES

As a sugar technologist, Meade is manager of the Colonial Sugars Company’s refinery at Gramercy, a director of the Cuban-American Sugar Company and co-author of the Spencer-Meade “Cane Sugar Handbook,” standard reference on sugar technology. As a snake expert, he is former vice-president of the American Society of Ichthyologists and Herpetologists. As an aquatics enthusiast, he is former vice-president of the Southern AAU and a member of the AAU Committee on swimming.
NEW for the ZOO
Lemur, rarely seen in this country, was adopted by Harf Hoogstraal on recent expedition into Madagascar. Monkey-like creature has 14-inch tail, drinks beer and champagne, will aid medical research.
$2500 Pig is no common variety of pork-on-the-hoof; he’ll be going Hollywood, soon. Porky is four years old and was born with only two legs, but he has learned to use them well. Piggie’s sponsor is a California carnival man, Charles Simpson.
