Safe!
How can an umpire be sure a runner has reached first base? In 1875 inventor John O’Neill suggested fitting it with a bell to “indicate clearly and positively, without chance of error, the exact moment when the base is touched by the runner.”
The trouble is that the “enunciating base” will also sound when the first baseman steps on it. Ten years later William Williams suggested an electric bell, which could be heard more clearly by a single umpire behind home plate, but it faced the same objection. Both were forgotten.
Perspective
Artist Markus Raetz erected this sign on the Rue du Rhône (at Place de la Fusterie) in downtown Geneva. What it says depends on where you stand.
Here’s a similar idea exhibited in a gallery:
Vinkensport
Each year, thousands of people take up seats along the streets of Flanders. Before each of them is a wooden box, and in each box is a single male finch. At a timekeeper’s signal, the observers begin to count the birds’ calls, making tally marks on long wooden sticks. After one hour, the bird that has sung the most calls is recognized as the winner.
This is vinkensport, a tradition in Flemish culture for more than 400 years. It was started by merchants in 1596, and as of 2007 an estimated 13,000 vinkeniers were still breeding 10,000 birds each year.
The sport’s popularity is growing, but like any sport it’s subject to cheating: When one finch produced 1,278 susk-e-wiets in an hour, its owner was accused of doping it with testosterone. Another competitor attracted suspicion when his box emitted exactly 725 calls in each of two matches; when a judge ordered the box opened, he discovered a mini-CD player inside.
Departing the Club
At London’s prestigious Atheneum a venerable retainer reported to the club manager that member Prestwick was asleep in his favorite wing chair with a copy of The Times folded across his face. ‘What’s so unusual about that?’ asked the manager. ‘Member Prestwick has always slept in that chair with The Times folded across his face.’
‘I know, sir,’ replied the retainer, ‘but it’s yesterday’s Times.’

Return to Sender
This just caught my eye: Competitive boomerang throwers participate in a number of events: distance, accuracy, trick catches, and so on. One of the most popular of these is maximum time aloft, in which the goal is to keep the boomerang in the air as long as possible with a single throw.
Unbelievably, the record here is 17 minutes and 6 seconds, set by John Gorski of Avon, Ohio, in 1993. At the time a respectable flight might last 30 to 40 seconds, but Gorski’s boomerang hit a thermal that carried it upward an estimated 200 meters, where it hovered for several minutes over the Olentangy River. It drifted south for 225 meters, then headed north again, descending to find Gorski, who managed to catch it 40 meters from where he’d thrown it.
“I couldn’t believe I’d got it back,” Gorski said later. “I thought, ‘I’m never going to see this boomerang again,’ but then it stopped drifting and just hung there.”
Tournament director Chet Snouffer called it “an unbelievable, once-in-a-lifetime experience — he caught the perfect wave and surfed it right into the record books.”

“I was tossing around the names of various wars in which both the opponents appear: Spanish-American, Franco-Prussian, Sino-English, Russo-Japanese, Arab-Israeli, Judeo-Roman, Anglo-Norman, and Greco-Roman. Is it a quirk of historians or merely a coincidence that the opponent named first was always the loser? It would appear that a country about to embark on war would do well to see that the war is named before the fighting starts, with the enemy named first!” — David L. Silverman
Lost Treasure
Robert Louis Stevenson’s original map of Treasure Island was lost during publication. He sent it to his editor and was “aghast” to learn that it was never received. “I had written it up to the map,” he wrote — most of the novel’s plot had been inspired by the picturesque map he had dreamed up at the start. Now he had to redraw it working backward, inferring the island’s layout from the descriptions in the text.
It is one thing to draw a map at random, set a scale in one corner of it at a venture, and write up a story to the measurements. It is quite another to have to examine a whole book, make an inventory of all the allusions contained in it, and with a pair of compasses, painfully design a map to suit the data. I did it; and the map was drawn again in my father’s office, with embellishments of blowing whales and sailing ships, and my father himself brought into service a knack he had of various writing, and elaborately FORGED the signature of Captain Flint, and the sailing directions of Billy Bones. But somehow it was never Treasure Island to me.
“It is, perhaps, not often that a map figures so largely in a tale, yet it is always important,” Stevenson wrote. “Even with imaginary places, [the author] will do well in the beginning to provide a map; as he studies it, relations will appear that he had not thought upon; he will discover obvious, though unsuspected, short-cuts and footprints for his messengers; and even when a map is not all the plot, as it was in Treasure Island, it will be found to be a mine of suggestion.”

Northwest Passage
When Portland, Oregon, carpeted its airport in 1987, it chose a bold design in blues and greens rather than the unmemorable beige underfoot in most American terminals. Designer John Schleuning composed a pattern that reflected the airport’s intersecting North-South runways as seen from the control tower, and the result became a surprise hit, with its own Twitter account and 20,000 pictures on its Instagram hashtag.
Twenty-six years later, the unthinkable happened: The carpet reached the end of its life, and the airport set about replacing 14 acres of it, fashioning one 11×16-foot section into a memorial collage and giving away much of the rest as keepsakes.
The city went into mourning. “We understand that people have an emotional connection to the carpet,” Port of Portland spokeswoman Annie Linstrom told Portland Monthly, uttering this sentence for the first time in human history. The chief operating officer added, “Normally we do these ribbon cuttings when we’re introducing a new thing, but it’s actually the reverse of that in removing the old carpet. We’re going to miss the carpet and we appreciate the community and the love of this carpet.” The Monthly even published an elegy, “Ode on a Carpet,” by “T.S.A. Eliot.”
You can still keep the old carpet underfoot, though, for a price: Portland Trail Blazers point guard Damian Lillard has added the design to two models of his Adidas D Lillard sneakers, below, and you can buy some socks to go with them.
