Right of Way
Theodore Roosevelt’s friend Jacob A. Riis remembers an encounter with Slippers, the White House cat, during a state dinner in 1906:
The dinner was over, and the President, with the wife of a distinguished Ambassador on his arm, led the procession from the state dining-room along the wide corridor to the East Room at the other end of the building, the ambassadors and plenipotentiaries and ministers following, according to their rank in the official world, all chatting happily with their ladies, seeing no cloud on the diplomatic horizon; when all of a sudden the glittering procession came to a halt. There, on the rug, in the exact middle of the corridor, lay Slippers, stretched at full length, and blinking lazily at the fine show which no doubt he thought got up especially to do him honor. The President saw him in time to avoid treading on him, and stopped. His first impulse was to pick Slippers up, but a little shiver of his lady and a half-suppressed exclamation, as he bent over the cat, warned him that she did not like cats, or was afraid, and for a moment he was perplexed. Slippers, perceiving the attention bestowed on him, rolled luxuriously on the rug, purring his delight. No thought of moving out of the path was in his mind.
There was but one other thing to do, and the man who found a way to make peace between Russia and Japan, did it quickly. With an amused bow, as if in apology to the Ambassadress, he escorted her around Slippers, and kept on his way toward the East Room. Whereupon the representatives of Great Britain, and of France, of Germany, and Italy, of all the great empires and of the little kingdoms clear down to the last on the long list, followed suit, paying their respects to Slippers quite as effectually as if the war-ships of their nations had thundered out a salute at an expenditure of powder that would have kept a poor man comfortable for a year, and certainly have scared even a White House cat almost to death.

Storm Warning
How do you design a burglar alarm for people who can’t hear? Arnold Zukor came up with this solution in 1912 — when the burglar opens a door or window, a system of racks and gears opens a faucet and sprays the occupant through a nozzle mounted over the bed. “Alarm is thus given.”
If you leave your house during the day, you can disable the door alarm and direct the nozzle outside. Then if the window is opened, the flow of water will be visible from a distance, “indicating thereby the entrance of unauthorized persons into the building.”

Reasonable to ask young people to be adventurous, to go to the North Pole, say: but religion asks them to start off, without being sure if there is a North Pole.
Three pieces of earnest advice from the Revd. H.J. Bidder, aged 86, after sitting silent, with a crumpled face, all through dinner, and once loudly asking the man opposite who I was:
1. Never drink claret in an East wind.
2. Take your pleasures singly, one by one.
3. Never sit on a hard chair after drinking port.

A few adventures of Dashiell Hammett, who worked for the Pinkerton Detective Agency before turning to fiction:
- “I know a man who once stole a Ferris-wheel.”
- “I was once engaged to discharge a woman’s housekeeper.”
- “I was once falsely accused of perjury and had to perjure myself to escape arrest.”
- “A man whom I was shadowing went out into the country for a walk one Sunday afternoon and lost his bearings completely. I had to direct him back to the city.”
- “Three times I have been mistaken for a Prohibition agent, but never had any trouble clearing myself.”
- “I know an operative who while looking for pickpockets at the Havre de Grace race track had his wallet stolen. He later became an official in an Eastern detective agency.”
- “I know a detective who once attempted to disguise himself thoroughly. The first policeman he met took him into custody.”
- “In 1917, in Washington, D.C., I met a young woman who did not remark that my work must be very interesting.”
- “The chief of police of a Southern city once gave me a description of a man, complete even to a mole on his neck, but neglected to mention that he had only one arm.”
Interestingly, he notes that “the chief difference between the exceptionally knotty problem confronting the detective of fiction and that facing the real detective is that in the former there is usually a paucity of clues, and in the latter altogether too many.”
(“From the Memoirs of a Private Detective,” The Smart Set, March 1923.)
Lost in Translation
In January 1968, North Korea captured the American spy vessel Pueblo and held 82 crew members captive for 11 months. During the crisis, the North Korean government released the photo above, claiming that the Americans were apologetic and cooperating with their captors.
The Americans managed to send a different message — three of them are extending their middle fingers. They had told the Koreans this was a “Hawaiian good luck sign.”
Commander Lloyd M. Bucher found a way to accomplish the same thing verbally — he wrote the confession “We paean the DPRK [North Korea]. We paean their great leader Kim Il Sung.”

Mark Levi notes an interesting coincidence in Why Cats Land on Their Feet (2012): Dividing normal human body temperature (in Celsius) into 100 approximates e:
“The estimate will be on the low side if you run a fever, or on the high side if you have hypothermia,” Levi writes. “This observation makes the natural logarithm — the one with the base e — seem even more natural.”
Podcast Episode 92: The Forgotten Amendment
In 1982, college sophomore Gregory Watson got a C on a term paper arguing that a long-forgotten constitutional amendment could still be ratified. In this week’s episode of the Futility Closet podcast we’ll follow his 10-year mission to prove his professor wrong and get the amendment added to the Constitution.
We’ll also learn an underhanded way to win a poetry contest and puzzle over how someone can murder a corpse.
Last Wishes
British Army gunner Frank Bracey wrote this letter to his wife in May 1916 and left it to be opened in the event of his death:
Dearest Win
I am writing just a line Win in case of accidents. Just to let you know how I have always loved you Dear. You are the best little girl on God’s earth have I told you before. But I am writing this because I have a feeling that I shall not come back again. I have most of your letters in this box Dear and I wish you to have them and the cards. You may think I am a bit taped writing this dear but I cannot help it. If I do come back dearest you will never see this letter but I have a strong feeling that I shall never see England again. In case I do pop under the earth I want you to be happy and look out for a worthier chap than your Humble, you have been every thing to me Win. I know your love is mine forever dearest but if I do not come back I wish you the best of happiness and a good husband. I know you told me what you would do for yourself if I did not return but Win for the sake of our love I wish you to be brave, it would be hard for you little girl I know, but do nothing of the kind. My last wish is that you marry a good man and to be happy and to think of your Humble now and then. I felt I must write these few lines Win but whatever happens dear just keep a stout heart and think that your Frank did his bit for the women of this little isle. I expect you will think your Humble crazy but I was never saner than I am now.

Neighborly
Cimarron County, Oklahoma, is the only county in the United States that borders four states (Colorado, Kansas, New Mexico, and Texas).
It’s also the only U.S. county to border six counties in five different states (two in Texas and one each in Colorado, Kansas, New Mexico, and Oklahoma).
