Spring Fever

Inventors Neil and William Winton patented this “parakeet exercise perch” in 1957, in hopes of improving bird morale:

Parakeets are fast becoming common household pets and one of the first objectives of the new owner of a parakeet is to teach the parakeet to utter words that will amuse the owner thereof. …

An object of the present invention is to provide an exercising perch which will facilitate getting a parakeet in a cheerful state of mind so as he will talk or chatter more profusely.

The coil is designed so that “when a parakeet alights on any one of the coils, it will bounce up and down, sway with the weight of the bird, and oscillate back and forth.” The cage-mounted version shown here is only one option; the Wintons also envisioned a free-standing model and one that can be mounted on a wall (which is “entertaining to a parakeet possessing the ability to nose dive through a sleeve member”).

I don’t know how the parakeets responded. If they conquer the earth someday, perhaps they’ll give each of us a trampoline.


In 1853, a writer to Notes & Queries observed that the third line of Gray’s Elegy can be transposed 11 different ways while retaining its sense:

The ploughman homeward plods his weary way.
The weary ploughman plods his homeward way.
The weary ploughman homeward plods his way.
The ploughman, weary, plods his homeward way.
The ploughman weary homeward plods his way.
Weary the ploughman plods his homeward way.
Weary the ploughman homeward plods his way.
Homeward the ploughman plods his weary way.
Homeward the ploughman weary plods his way.
Homeward the weary ploughman plods his way.
The homeward ploughman weary plods his way.
The homeward ploughman plods his weary way.

“It is doubtful whether another line can be found, the words of which admit so many transpositions, and still retain the original meaning,” he wrote. Forty-two years later, the editors of Miscellaneous Notes and Queries proved him right, filling four pages with 252 transpositions:

Plods the ploughman, weary, his homeward way.
His weary way the homeward ploughman plods.
Homeward plods his way the ploughman, weary.
His homeward way the weary ploughman plods.
The weary ploughman homeward plods his way.
The homeward ploughman, weary, his way plods.
The weary ploughman plods his way homeward.
Plods the weary ploughman his way homeward.
Weary, the ploughman plods his homeward way.
His way homeward plods the weary ploughman.
Plods, weary, the ploughman his way homeward.
Weary his way plods homeward the ploughman.
The ploughman, weary, homeward plods his way.
His way plods homeward the ploughman, weary.
Homeward, weary, the ploughman his way plods.

They even offered a year’s subscription to any reader who could add to the list. I can’t tell whether anyone took them up on it — perhaps they were too tired.

Riddling Letters

In 1891 the Strand ran two features on oddities encountered by the British post office, which kept facsimiles of the most puzzling letters in three great scrapbooks. “Many a pictorial curiosity passes through the post; and the industrious letter-sorter is often bewildered as to where to despatch missives, the envelopes of which bear hieroglyphics which would positively out-Egypt Egypt.”

Some examples are merely helpless, such as the direction above or a letter intended for Pamber, near Basingstoke, Hants., which was addressed “Pambore near Beas and Stoke, Ence.” Elsewhere, “A seafaring man evidently expected at the Sailors’ Home is addressed, ‘Walstrets, Selorshom Tebiekald for’; which, being interpreted, means, ‘Sailors’ Home, Wells-street: To be called for.”

But others seem deliberately elusive — one letter bore only these lines:

This one:

… was intended for Swansea in South Wales.

“One envelope has an ingenious direction on it. It is intended for S.S. Kaisow, lying in the Red Sea. It shows a very deliberate-looking sow labeled K, with a belt round it in the form of the letter C painted red.”

But at least those letters had envelopes. One thrifty correspondent simply wrote his message on the back of a postage stamp and dropped it in the mail:

“Meet me to-night without fail. Fail not — I am hard up.” “Though he probably parted with his last penny,” note the editors, “considering the state of his exchequer, he ran a great risk of remaining still hard up, owing to non-delivery of his communication.”

Amazingly, many of these letters actually found their recipients, a testament to the diligence and imagination of the postal authorities. “But we are rather in doubt as to whether a communication from the United States addressed to ‘John Smith, Esq., or any intelligent Smith, London, England,’ or possibly a proposal from some unknown admirer for ‘Miss Annie W—, London, address not known,’ ever reached their rightful owners.”


An ignorant Yorkshireman having occasion to go to France, was surprised on his arrival to hear the men speaking French, the women speaking French, and the children jabbering away in the same tongue. In the height of the perplexity which this occasioned, he retired to his hotel, and awakened in the morning by the cock crowing, whereupon he burst into a wild exclamation of astonishment and delight, crying, ‘Thank goodness! there’s English at last!’

Here’s a philosophical question. Some pinball machines reward high scores with free replays. And in states with anti-gambling statutes, some prosecutors crack down on this feature, saying that it constitutes gambling.

Is this a coherent argument? If pinball is legal, then can more pinball be illegal?

“The prosecutors … believe that ‘more of the same’ can be too much of a good thing, and rather than multiply legal acts, actually cross the line of legality,” writes Peter Suber in The Paradox of Self-Amendment.

“A quantitative change becomes at some point a qualitative change, just as lowering the temperature of water by degrees gives us nothing but cold water for a while, and then suddenly gives us ice.”

Soul Mates

Lewis Carroll discerns a public danger in birthday toasts, from a letter to Gertrude Chataway, Oct. 13, 1875:

I am very much afraid, next time Sybil looks for you, she’ll find you sitting by the sad sea-wave, and crying ‘Boo! hoo! Here’s Mr. Dodgson has drunk my health, and I haven’t got any left!’ And how it will puzzle Dr. Maund, when he is sent for to see you! ‘My dear Madam, I’m very sorry to say your little girl has got no health at all! I never saw such a thing in my life!’ ‘Oh, I can easily explain it!’ your mother will say. ‘You see she would go and make friends with a strange gentleman, and yesterday he drank her health!’ ‘Well, Mrs. Chataway,’ he will say, ‘the only way to cure her is to wait till his next birthday, and then for her to drink his health.’

“And then we shall have changed healths. I wonder how you’ll like mine! Oh, Gertrude, I wish you wouldn’t talk such nonsense!”

A mother takes two strides to her daughter’s three. If they set out walking together, each starting with the right foot, when will they first step together with the left?
