Sea Lions Helped to Detect U-Boats

1919

Design of Hydrophone Was Changed to Resemble Head of Acute Water Animal.

In the late months of the war some wild stories were published to the effect that the British naval authorities were training sea lions to catch German submarines. Of course this was ridiculous, but the story was based upon a fact, and that fact has only just been revealed.

It was at the recent meeting of the British Association for the Advancement of Science, when Sir Charles Parsons, the president, delivered an address on "Science in War and Peace." In it he described the development of the binaural hydroplane, with which submarines are located by the sound they make. Early in the game it was discovered that the first forms of these instruments were useless when the vessel bearing them was in motion or when the sea was rough, because the noises made by the vessel's motion and by the waves drowned the noise of the submarine. This is where the sea lions came in.

Hear at Six Knots an Hour.

Sir Richard Paget, the eminent biologist, made experiments to learn how far these interesting animals could hear under water and at what speed their directional hearing ceased. These proved that the directional hearing of the lions was good up to six knots an hour.

Dr. Arthur Keith informed the naval experimenters that whales' ears are too small to receive sound waves in the usual way, but that the animals heard under water by the transmission of sound waves thru the bones of the head.

Design Was Changed.

Now, the whale's organ of hearing resembles the hydrophone. So the design of this was changed, and those used in the last year of the war were hollow bodies in the form of fish or porpoises, made of celluloid, varnished canvas or thin metal, filled with water and towed by the ship. The hydrophone was fixed in the head, and the towing cable carried the insulated wire leads to the telephone receivers of the observer on board the vessel.

These were towed some distance behind the ship, thus losing most of the noises made by the swift motion of this, and it was found that they registered directional sounds when traveling thru the water at speeds of fourteen knots and at considerable distances.

Largest of Animals

1901

Mr. Beddard in his book on whales reminds readers that although imagination is apt to picture the giant reptiles of the Jurassic and Cretaceous periods as having exceeded in size all modern animals yet in fact there is no evidence that the earth has ever contained either on the land or in the sea creatures exceeding the whale in bulk. The mammoth was larger than the elephant, but the ichthyosaurus could not match the whale for size, although with its terrible jaws it would doubtless have been the whale's master.

Report Real Sea-Serpent

1905

Rudyard Kipling has seen his second sea serpent, according to a story which comes with some seriousness from Cape Town. People who read Kipling's first sea-serpent story thought it was merely a brilliant piece of fiction. This second sea serpent story is not told by Kipling, but by the skipper of the steamship Armadale Castle. The sea serpent was seen — in fact, it was struck by the ship and probably killed — while the Armadale Castle was on her last voyage to Cape Town, in latitude 3 degrees south. Mr. Kipling was aboard the ship.

Commander Robinson is not sure whether the creature struck was a real sea serpent, a queer whale or a greatly overgrown shark. Whatever it was, the thing was hit by the bow or the ship where, in all properly regulated fishes, the pectoral fin exists. The head was doubled across the port bow and the tail trailed away along the starboard side. The violent struggles of the creature to free itself from its painful and embarrassing position led to its striking the soft brown paint of the "boot-topping" on the ship's side with the powerful fluke of its tail.

This was observed by the boatswain and some of the men who were watching the affair through the side ports immediately over the tail of the fish. The marks enabled the commander afterward to make fairly accurate measurements. From mark to stem it was forty-five feet. In girth it was apparently about the volume of one of the ship's lifeboats at the broadest part, say eight feet in diameter, very gracefully tapering away toward the tail. The body appeared to be of a greenish-brown color with large dark spots all over the back and sides, the lower parts being of a dull white.

It was first observed by one of the seamen, who heard a knocking against the ship's side. When the news was passed along the decks all the passengers, young and old. performed a mad stampede into the forecastle to look at the unhappy prisoner. The engines were stopped as soon as possible and reversed, but fully a quarter of an hour elapsed between the first discovery and the final clearance, by which time the creature was either dead or completely exhausted, for it sank slowly, tail first.

Whale Fought Ocean Liner

1905

The Pacific Mail Company's liner Acapulco, which arrived early yesterday morning from Panama and way ports, had an exciting experience with a whale off San Blas. The leviathan, floating high out of the water, was enjoying a morning nap and giving its tough hide a sunbath, when the Acapulco came along.

The lookout sighted the whale and called the attention of the man at the wheel to the slumbering mountain of flesh that floated directly in the liner's path. The quartermaster, who was steering, gave the spokes of the wheel a twist and the Acapulco's head sheered off a little. A collision was avoided, but the Acapulco's side grazed the starboard shoulder of the big fish and jarred the whale from slumberland.

The whale was fully awake before the liner had entirely passed. He awoke in a bad temper and made a furious rush at the Acapulco's stern. The whale found the disturber of his dreams a pretty solid sort of fish, but, undaunted by his failure to ram his head through the steel plates, gathered himself for another charge.

He struck the steamer under the stern, and as he bounced off, slashed at the retreating hull with his tail. Then one more rush. This time the whale found his match, for the rapidly revolving propeller landed a bewildering succession of uppercuts on his lower jaw. With a splash of defiance, the leviathan dived and disappeared and the people of the Acapulco saw him no more.

Chief Officer Bailey interviewed the quartermaster, who had avoided the whale by such a narrow margin, and concluded a heart to heart sailor talk by advising the steersman in future to "let sleeping whales lie." — San Francisco Call.

Eating Parrots, Albatross, Weeds, Acorns

1896

Food Can Be Almost Anything

Few of us, or, indeed, of any people, would think of eating parrots, especially if anything else could be gotten, yet the Romans esteemed them for the table, the Boston Traveller writes.

Cranes are sometimes used for food.

The American ostrich, of South America, is eaten, both flesh and eggs. The eggs of the African ostrich are used, and the flesh, when the bird is young.

The albatross, largest and strongest of birds, produces eggs that are edible.

There is a weed in this country, much cursed by all who have to do with the soil and its products, called a vulgar phrase "pussly." No one in this country would think of eating it, yet this foe of farmers and gardeners is used as a salad in Europe and Egypt.

Acorns in this country are put to no use, unless it be for swine; but in Saxon times "mast" was valued not only for herds, but for man. In times of dearth acorns were boiled and eaten by the poor in England and in France, as one species is still in Southern Europe.

Whales are no longer eaten by civilized men, but in the thirteenth century their tongues were held in great esteem in parts of Europe. Whales are now, with seals and walruses, the chief food of many inhabitants of the Arctic regions. Of the narwhal the Greenlanders eat flesh, fat and skin.

Isinglass is a strange food; it is a gelatin prepared from the air bladders of different kinds of fish from large rivers that flow into the North and Caspian Seas.

Beauty – Calling a Woman "Pretty" is Merely Conventional

1877

Pretty women are spoken of as if they, of all others, were the elect; as if woman's sole claim to admiration rested on her possession of fine eyes or luxuriant hair. "Is she pretty?" is the first question asked concerning a new acquaintance, as though that embraced the whole subject.

If a man likes a woman he generally considers her "pretty," for the term is merely conventional. A pretty woman, in the private lexicon of masculinity, signifies a woman interesting from whatever cause. Who has not known women to be called pretty that could hardly boast of a single handsome feature? Who has not been acquainted with those enjoying a wide reputation for prettiness that had almost any other than a physical charm? She who has a distinctly graceful manner, or an elegant air, or fine tact, or a talent for conversation, or quick sympathies, or cordial ways, or a heart of listening well, albeit plain in face and of ordinary figure, is frequently styled pretty, and the adjective is repeated until it is fastened upon and constantly associated with her.

Merely pretty women do not rule society — never did and never will. When beauty is allied to pleasant manners, or accomplishments, tact, quick wit, then, indeed, it is all-powerful; otherwise a really plain woman who had conspicuous graces of mind and manner will prove more than a match for her beautiful, insipid sisters.



Jonah and the Whale

A naturalist walks boldly to the front and announces that the preservation of Jonah in the whale's belly was not a miracle. The throat of the whale is large, and is provided with a bag or intestine, so considerable in size that the whales frequently take into it two of their young ones when weak, and especially during a tempest. As this receptacle is furnished with two vents that serve for inspiration, it is claimed that Jonah could have lived there comfortably and, with reasonable amount of furniture, many years, provided he could obtain food and drink.



Emotions of a Mother's Heart

A mother may never find words in which to express the emotions which surge through her heart on finding her babe, just dressed in its Sunday best, stirring the contents of a bottle of ink into the coal ashes with the hair-brush but she will try to, and try with all her might.

A Remarkable Clock – Magnetism Runs It

1878

A Remarkable Clock.

A magnetic clock, invented by Daniel Drawbaugh, of Milltown, Cumberland county, Pa., is sufficiently remarkable to be worth description.

The magnetism of the earth, an inexhaustible source of power, is made to oscillate the pendulum; and the simplicity of all the works gives an assurance of the least possible friction. At a certain point the movement of the pendulum itself shuts off magnetic connection with the earth, and at another point restores the connection, thus securing the conditions necessary to produce its oscillations. The works are so ingenious and simple that it is no wild assertion to make that, were it not for the unavoidable wearing out caused by even the smallest amount of friction, the clock would run as long as the solid earth endures.

This clock is hung against a board partition, with all the works exposed, subject to the jarrings of machinery and obstructions from dust settling upon it, yet since March 1, 1877, it has been running continuously and uniformly, with only slight reported variations, as tested by transit observations at noon.


Whaling News

The American whaling fleet of 1877 was very successful. There were no special disasters, and no changes in the business worthy of note, excepting the continued additions to the fleet. Twelve vessels were built during the year. The present fleet consists of 187 vessels, against 172 on January 1, 1877, 169 in 1876 and 163 in 1875. The North and South Atlantic ocean employ over 100 vessels, while the more fruitful grounds of the Pacific ocean, Japan and New Zealand are almost deserted. The North Pacific fleet lost three vessels, and sixteen vessels came out with an average of 1,065 barrels of oil and 8,550 pounds of whalebone.
