The interrogative phrase why is a mouse when it spins? is nonsensical; it usually entails the equally nonsensical answer because the higher the fewer. (This is similar to what’s the difference between a duck?, entailing one of its legs is both the same.)
—Cf. also the nonsensical origin of Kilkenny cats and time flies? you cannot: they go too fast.
IN BRITISH ENGLISH
The phrase seems to have originated in British English as when is a mouse if it spins?. The earliest occurrence that I have found is, together with the answer the higher it gets the fewer, from The Cornish Telegraph, and Mining, Agricultural, and Commercial Gazette (Penzance, Cornwall, England) of Thursday 29th December 1892:
THE RIDDLE THAT TURNED MY BRAIN.
The following is taken from a Birmingham paper:—I always thought there was insanity in my family. Now, I know it, and can prove it. The hereditary poison might never have broken out if it hadn’t been for Smoogleslush—l blame. I was all right till that awful evening when he asked me the riddle that cracked my brain. I tried to solve it—until I solve it I am mad—l shall never solve it. My only hope is that the problem I am going to make public will turn other brains too. He took me unawares. He said abruptly, “You’re pretty good at riddles, Flarehead, aren’t you?” “We’ll [sic] I’ve guessed a few,” I said, modestly. “I’m afraid mine’s too simple, too obvious,” said Smoggleslush [sic], “but such as it is, here goes: ‘When is a mouse if it spins?’” “I beg your pardon. ‘When is a mouse if it spins?’ What do you mean?” “That’s the riddle.” “Oh, that’s the riddle. ‘What is a mouse if it spins?’” “No, no, simpler than that. I said, ‘When is a mouse if it spins?’” “You’ve got it wrong, Smoogleslush.” “Not at all. There is no sort of trouble about the question; the cleverness, the clearness comes in with the answer.” “What is the answer?” “It’s a splendid one, make you wonder why you could not see it before. You’ve got the question all right.” “I have.” I said firmly, “‘When is a mouse if it spins?’” “That’s right. Because—the higher it gets the fewer. Ha! ha! ha! ha! See it!” “Yes,” said I. “Plain as a pikestaff, isn’t it?” “Plainer.” Smoogleslush left me. I was left, as it were, face to face, with that awful riddle. If he could see it, why couldn’t I? I repeated it over and over again but every time my brain grew worse. Why couldn’t I see it? My blood curdled as the conviction grew upon me that something had gone wrong with my brain. I decided to go home and try it on my wife. I would pretend I saw the point, and see how it fetched her. She was sitting up for me. I said at once “Ha! ha! Capital riddle for you, my dear. ‘When is a mouse if it spins?’ Because—‘The higher it gets the fewer,’ Ha! ha ! ha!” She looked at me steadily, and I felt myself quailing beneath her gaze; she didn’t laugh a single laugh. “Charles,” she said, “didn’t you once tell me your uncle died in a madhouse!” “Yes,” I replied, “he did. Where are you going?” “Back to dear mother,” she said as she slipped out of the door, never more to enter it. I didn’t try to stop her. I resolved to sit up and understand that riddle or burst. Far into the night I kept on at it, repeating that gruesome question and that weird reply. At length I sallied out into the calm night. I had remembered the sweet refrain of a hymn my mother taught me when a child—“Ask a policeman.” I would; I saw one. I said “Ha! ha! When is a mouse, &c. Ha! ha! ha! Whey [sic] the deuce don’t you laugh?” He struck me on the head, and I fell into the gutter, murmuring, “When is a mouse if it gets higher, because the fewer it gets it spins.” Somebody dragged me to a doctor, and I said at once, “When is a spins if he gets fewer because the mouse it gets the higher?” I heard the doctor say he was quite willing to sign the certificate. I had been standing before a bald-headed J.P., and demanded, “Because is a gets if its mouse when a fewer it hires the spinners, ah! ah! ah!” He signed at once, and they brought me to Winson Green. I know I am mad, but there is no reason why they should ask me, “When is a mouse if it spins?”
The second-earliest occurrence of the phrase that I have found is, as when is a mouse if it spins?, from the Dorking Advertiser (Dorking, Surrey, England) of Thursday 2nd February 1893:
Entertainment.—The Y.M.C.A. provided a thorough change in the way of entertainment on Wednesday evening. The major part consisted of a series of recitals by that popular elocutionist, Mr. Granville Jaggs. […] The conundrum “When is a mouse if it spins?” by its irresistably [sic] comic delivery drew roars of laughter from all.
The phrase then occurs as why is a mouse when it spins?, together with the answer the higher the fewer, in the following from Ally Sloper’s Half Holiday (London, England) of Saturday 4th March 1893:
New riddle by Mr. McGooseley, after an unusually heavy week: Q. Why is a mouse when it spins? A. The higher the fewer—hic! The Mac—hic!—says he’s got many more quite as original.
The phrase occurs as why is a mouse, if it spins in this advertisement, published in The Era (London, England) of Saturday 16th December 1893:
Why is a mouse, if it spins (Because——).
Character Comedian and Dancer,
concludes To-night, usual success, Grand, Manchester.
Monday next, NEW EMPIRE, LEICESTER.
The following is from Notes on News, published in The Yorkshire Evening Post (Leeds, Yorkshire, England) of Saturday 28th April 1894:
It would be interesting to know the exact state of mind left in the mind of a man ignorant of the game of golf, after reading the description of the final ties for the Amateur Championship at Hoylake. For the phraseology of the “Royal and ancient game” is more bewildering than that of the Prize Ring, or the football field. Why should it be that “playing to the first hole Mr. Laidlay topped his drive”? It conveys no more meaning to the average man than the statement that “Mr. Ball missed his put to halve,” which very much reminds one, in its apparent meaninglessness, of the old conundrum “Why is a mouse when it spins?” to which the answer is “The higher the fewer.” Golf is a greater puzzle than that.
And the following is from The Post Bag, published in the South Wales Daily Post (Swansea, Glamorgan, Wales) of Tuesday 31st July 1894:
A well-known inn, not far from Goat-street, is just now agitated over the abstruse question: Why is a mouse when it spins? And over the still more abstruse answer: Because the higher the further! This reminds us of the recent conundrum: Why is a fly when it’s a wall? And the mystic response: Because—may God save Ireland!
IN AMERICAN ENGLISH
The earliest American-English occurrence of the phrase that I have found is from the column Society Events, published in The Salt Lake Tribune (Salt Lake City, Utah) of Sunday 23rd July 1893:
Mr. Will Smedley has invented a new puzzle, which he has had patented, and an Eastern firm declares it is great.
It is called “Columbus Discovering America,” and a most intricate affair to work out.
Will is a clever boy at these sort [sic] of things and fully expects to reap a few hundred thousand on his latest invention.
As well remembered he is the originator of the now famous “House That Vanderbilt,” 1 “Hand That Westerfelt” 2 and “Why Is a Mouse When It Spins?”
1 The U.S. businessman and philanthropist Cornelius Vanderbilt (1794-1877) amassed a fortune from shipping and railroads.
2 I have not discovered whether Westerfelt may refer to a specific person.
The phrase why is a mouse when it spins? then occurs, together with the answer the higher the fewer, in the column The Bohemian, published in The Buffalo Enquirer (Buffalo, New York) of Thursday 20th September 1894:
Next time you meet John N. Scatcherd ask him “why is a mouse when it spins?” and he will say “the higher the fewer.” To those who do not understand the circumstances this may not be funny, but it is, just the same, and Mr. Scatcherd will either laugh heartily or grow real angry.
The following story appeared in The Salt Lake Herald (Salt Lake City, Utah) of Wednesday 8th April 1896:
“WHY IS A MOUSE WHEN—?”
Perfidous [sic] Conundrum Sprang Upon a Peaceful Town by an Enemy of Mankind.
Deputy Collector Thomas J. Dunn, of the marine division in the custom house, is a Harlem Democrat.
“He jollies himself along,” says District Leader McAvoy, “towards the millennium, and he jollies everybody on the way—that is a Harlem Democrat, a jollier.”
He lunched at Delmonico’s downtown yesterday with Deputy Haggerty, of the naval office.
“Now, we’ll have a little fun,” said Mr. Dunn to Mr. Haggerty. “I’ve got a new conundrum. Here it is: ‘Why is a mouse when it spins?’ You see, it is a fool thing and I don’t want you to go crazy—you must be my confederate. We’ll work it up together. The answer is: ‘Because the higher the fewer!’ Just laugh and pretend you see it when I spring it. Sh! here comes Gourley.”
Special Deputy Naval Officer Harrison W. Gourley, silk-hatted and solemn, entered. Gourley has spent thirty years solving customs enigmas. He has a way of interpreting the most puzzling grammatical problems ever incorporated in a tariff bill by a house ways and means committee.
“Come over, Gourley,” said Dunn, “I’ve got a new conundrum for you. ‘Why is a mouse when it spins?’”
“Why, because—why—he—let’s see—why is a mouse—why, darn it! it don’t make sense.”
“Of course it does,” said Haggerty.
“Well, I give it up,” said the special deputy naval officer in disgust.
“Because the higher the fewer,” said Dunn, without a semblance of a smile.
“Because the—what?—oh, hang it all!” and seizing his hat Mr. Gourley fled lunchless.
Then Superintendent Edward Powers of the cotton exchange came in for lunch.
Thus the maddening conundrum spread to the cotton exchange, where within an hour it had half the brokers stark mad. Somebody told it to Assistant Superintendent Beall of the produce exchange, and it got into the wheat pit. Business was suspended, and the brokers hunted chairs, and with pencil and paper wrote and wondered.
Thence it spread to the stock exchange, where, long after the markets closed, solemn-faced men paced the floor, repeating it to themselves.
It is said that when Russell Sage went up to the free lunch in the directors’ room of the Western Union, he ordered “A mouse when it spins, with a little of the higher the fewer.”
Meanwhile Special Deputy Gourley and Chief Clerk Andrew locked themselves in the naval office and struggled with the problem.
It was after 5 o’clock when Mr. Gourley was seen to rush out of his office and strike a bee line for Collector Kilbreth’s office. Breathless, he descended upon the collector.
“Mr. Collector, do you see any sense in this? ‘Why is a’”——
“Mouse when it spins?” gasped the collector, looking up from a pile of papers.
“See here, Gourley, I have troubles of my own. Why is a mou—because—because it—becausue [sic] the fewer—the higher be”——
And again Gourley fled. At the door of the rotunda he met Law Officer Phelps.
“Say, Gourley,” cried Colonel Phelps, “you’re good at conundrums. Why is a——”
But Mr. Gourley had disappeared.—New York World.
DISMISSIVE USE OF WHY IS A MOUSE WHEN IT SPINS?
Very early, why is a mouse when it spins? came to be used dismissively. The following paragraph is from the column Table Talk, published in The Buffalo Commercial (Buffalo, New York) of Saturday 14th November 1896:
“I have myself,” says Mr. G. Bernard Shaw 3 in the Roycroft edition deluxe of that author’s works, “tried the experiment of not eating meat or drinking tea, coffee or spirits for more than a dozen years past, without, as far as I can discover, placing myself at more than my natural disadvantage relatively to those colleagues of mine who patronise the slaughter house and the distillery—but then I go to church.” Well? Why is a mouse when it spins?
3 George Bernard Shaw (1856-1950) was an Irish playwright, critic, polemicist and political activist.
Likewise, the U.S. novelist John Dos Passos (1896-1970) used the phrase to dismiss both Alfred Tennyson 4 and John Ruskin 5 in a letter to his friend, Walter Rumsey Marvin, written from Paris in June 1919—as published in The Fourteenth Chronicle: Letters and Diaries of John Dos Passos (Boston: Gambit Incorporated, 1973), edited by Townsend Ludington:
I’m in a horrid mood today—and I feel like lecturing so you are getting the brunt of it—But Rummy my love, I hope you read something else in Freshman English than Shakespeare 6 Ruskin Carlyle 7 and Tennyson—Carlyle I’ll admit as a good old brute of a minor prophet, and of course Shakespeare is enough to counteract all ills—but why in Gods [sic] name Tennyson and Ruskin?—Why is a mouse when it spins?
4 Alfred Tennyson (1809-1892) was an English poet.
5 John Ruskin (1819-1900) was an English art and social critic.
6 William Shakespeare (1564-1616) was an English poet and playwright.
7 Thomas Carlyle (1795-1881) was a Scottish historian and political philosopher.
Since an early date, some people, taking leave of their common sense, have made up theories purporting to rationalise why is a mouse when it spins? because the higher the fewer. The following is from the column Stories of the Town, published in the St. Louis Post-Dispatch (St. Louis, Missouri) of Tuesday 6th December 1898:
HE KNEW—A company at the City Hall were amusing themselves at the expense of a man who never had heard the gag: “Why is a mouse when it spins.”
The men who knew the joke laughed immoderately each time the senseless question and its senseless answer, “The higher the fewer,” were repeated. The unhappy victim scratched his head and pondered, but couldn’t produce even so much as a smile.
The fun palled on the company and the victim escaped. About two hours later he sought out one of the jokers and with solemn manner thus addressed him:
“I have it. You put that riddle wrong. It shouldn’t be, ‘Why is a mouse when it spins?’ It should be, ‘What is a mouse when it spins?’ Then the answer. ‘The higher the fewer’ is correct, because the faster the mouse spins the higher it goes. Fewer in this case has the meaning of less. That is, the higher it spins the less, or the fewer, you see of it.”
He smiled triumphantly as he finished, and nobody had the heart to enlighten him.
Much more recently, on Monday 18th February 1991, in its column Notes & Queries, The Guardian (London and Manchester, England) published this explanation of why is a mouse when it spins?, given by one Patrick Nethercot, writing from Durham, in northern England:
This peculiar saying relates to a certain type of governor on steam engines, whereby revolutions of the engine are reduced if a spinning weight (mouse) is lifted up a shaft by its centrifugal force, releasing steam pressure and ensuring fewer revs: the higher, the fewer.
Such systems were common on static engines like those found originally in cotton mills in the heyday of the steam revolution.
One thought on “‘why is a mouse when it spins? because the higher the fewer’”
Thank you. I know less now than I did before, but I am happier for it. I found the riddle and solution in a science fiction book some 40+ years ago, about the same time I found;
Man is polygamous.
The meaning seems clear, but I haven’t located the source. If you haven’t already, you might look into it. 😀
