Cash and Carry

During the London Gin Craze of the early 18th century, when the British government started running sting operations on petty gin sellers, someone invented a device called the “Puss-and-Mew” so that the buyer couldn’t identify the seller in court:

The old Observation, that the English, though no great Inventors themselves, are the best Improvers of other Peoples Inventions, is verified by a fresh Example, in the Parish of St. Giles’s in the Fields, and in other Parts of the Town; where several Shopkeepers, Dealers in Spirituous Liquors, observing the Wonders perform’d by the Figures of the Druggist and the Blackmoor pouring out Wine, have turn’d them to their own great Profit. The Way is this, the Buyer comes into the Entry and cries Puss, and is immediately answer’d by a Voice from within, Mew. A Drawer is then thrust out, into which the Buyer puts his Money, which when drawn back, is soon after thrust out again, with the Quantity of Gin requir’d; the Matter of this new Improvement in Mechanicks, remaining all the while unseen; whereby all Informations are defeated, and the Penalty of the Gin Act evaded.

This is sometimes called the first vending machine.

Hidden Mothers

In the 19th century, photographic subjects had to hold still during an exposure of 30 seconds or more. That’s hard enough for an adult, but it’s practically impossible for an infant. So mothers would sometimes hide in the scene, impersonating a chair or a pair of curtains, in order to hold the baby still while the photographer did his work:

Podcast Episode 169: John Harrison and the Problem of Longitude

john harrison

Ships need a reliable way to know their exact location at sea — and for centuries, the lack of a dependable method caused shipwrecks and economic havoc for every seafaring nation. In this week’s episode of the Futility Closet podcast we’ll meet John Harrison, the self-taught English clockmaker who dedicated his life to crafting a reliable solution to this crucial problem.

We’ll also admire a dentist and puzzle over a magic bus stop.

A Soaring Heart

From an advice column in Home Companion, March 4, 1899:

‘Sweet Briar’ (Swansea) writes in great trouble because her lover will persist in his intention to go up in a balloon. She urges him not to imperil his life in this foolhardy manner, but he only laughs at her fears.

I am sorry, ‘Sweet Briar’, that your lover occasions you anxiety in this manner, and I can only hope that he will ultimately see the wisdom of yielding to your wishes. What a pity it is that we have not a law like that which exists in Vienna! There no married man is allowed to go up in a balloon without the formal consent of his wife and children.

One solution: Go up with him, and marry him there.

Prototype

In 2001, computer animator Wayne Lytle created “Pipe Dream,” a 3D music visualization in which falling balls trigger musical notes on vibraphones, tubular bells, bongos, and other instruments:

Entertainingly, in 2006 an email hoax claimed that the scene was not animated but real:

Amazingly, 97% of the machines components came from John Deere Industries and Irrigation Equipment of Bancroft Iowa, yes farm equipment!

It took the team a combined 13,029 hours of set-up, alignment, Calibration, and tuning before filming this video but as you can see it was WELL worth the effort.

The hoax was entertaining because it was preposterous — who could build such a thing in real life?

You can guess where this is going — in 2011 Intel created a real version in which 2300 paintballs trigger 120 unique notes on replicas of Lytle’s animated instruments:

That’s just 10 years after Lytle made the original animation.

In March 1913, Thomas James Cobden-Sanderson threw the most beautiful typeface in the world off of London’s Hammersmith Bridge to keep it out of the hands of his estranged printing partner. In this week’s episode of the Futility Closet podcast we’ll explore what would lead a man to destroy the culmination of his life’s work — and what led one modern admirer to try to revive it.

We’ll also scrutinize a housekeeper and puzzle over a slumped child.

For the Record

Western Kentucky University geoscientist John All was traversing Nepal’s Mount Himlung in May 2014 when the ice collapsed beneath him and he fell into a crevasse, dislocating his shoulder and breaking some ribs. He landed on a ledge, but now he faced a 70-foot climb back to the surface alone without the use of his right arm or upper leg.

“That’s when I pulled my research camera out and started talking to myself about all my options,” he told National Geographic. “I take photos of everything I do because, if I’m working in Africa and I need to recall a detail, that’s going to be the best way to do it. I was also thinking about my mom and my friends and family and realized that just talking wouldn’t convey what was happening to me nearly as well. So I started recording things.”

“It probably took me four or five hours to climb out,” he said. “I kept moving sideways, slightly up, sideways, slightly up, until I found an area where there was enough hard snow that I could get an ax in and pull myself up and over. I knew that if I fell at any time in that entire four or five hours, I, of course, was going to fall all the way to the bottom of the crevasse. Any mistake, or any sort of rest or anything, I was going to die.”

After reaching the top he rolled as much as walked back to his tent, called for help, and waited 16 hours for a helicopter to arrive. He wrote later, “I had dug myself out of my own grave.”

The Susquehanna Ice Bridge

susquehanna ice bridge

In the 1850s, railroad passengers traveling from Baltimore to Philadelphia would debark at the Susquehanna River, cross the river on a ferryboat, and board a train waiting on the other side. In the severe winter of 1852, so much floating ice had piled up at this point that the ferry couldn’t be used, so railroad engineer Isaac R. Trimble came up with a novel solution: He built a railway across the ice for the baggage and freight cars, and a sledge road beside it along which horses could draw his passengers. The cars had to descend 10 to 15 feet from the bank to the surface of the ice, and at the other side they were tied to a locomotive and pulled up. The “ice bridge” opened on Jan. 15 and was accounted a great success. The Franklin Journal reported, “Forty freight cars per day, laden with valuable merchandise, have been worked over this novel tract by the means above referred to, and were propelled across the ice portion by two-horse sleds running upon the sledge road, and drawing the cars by a lateral towing line, of the size of a man’s finger.”

“At the present writing, this novel and effectual means of maintaining the communication at Havre de Grace is still in successful operation, and will so continue until the ice in the river is about to break up. Then, by means of the sledges, the rails (the only valuable part of the track), can be rapidly moved off by horse power, not probably requiring more than a few hours’ time, so that the communication may be maintained successfully until the last moment. If properly timed, as it doubtless will be, the railroad may be removed, the ice may run out, and the ferry be resumed, it may be, in less than forty-eight hours.”

In fact, wrote historian Charles P. Dare, the ice bridge operated until Feb. 24, “when it was taken up, and, in a few days, the river was free of ice. During this time, 1378 cars loaded with mails, baggage and freight were transported upon this natural bridge, the tonnage amounting to about 10,000 tons. The whole was accomplished without accident of any kind; and the materials were all removed prior to the breaking up of the river without the loss of a cross-tie or bar of iron.”

In 2010 Jeremy Wood walked around the campus of the University of Warwick with a GPS device to “draw” a map at 1:1 scale. Altogether he covered 238 miles in 17 days.

“He stayed in the Maths Houses on Gibbet Hill so the line through Tocil Wood to the Mead Gallery is exceptionally dark since it was walked so many times,” the university reports. “As he worked his way across the fields towards Kenilworth he began to ‘draw’ images associated with the University, from its crest, to a mortar board, to a globe in homage to the many ‘international’ centres that he encountered in his journeys. Reported to security several times for walking in ‘a suspicious manner’ around Claycroft and Lakeside residences, he soon disappeared from view, walking the countryside that surrounds the University but which is far removed from central campus.”

“I responded to the structure of each location and avoided walking along roads and paths when possible,” Wood writes. “Security was called on me twice on separate occasions and I lost count of how many times I happened to trigger an automatic sliding door.” More at his website and at GPS Drawing.

By 1804, English engineer George Cayley was building model gliders that were remarkably similar to modern airplanes, with fixed wings, a body, and a tail. In the 1840s he built a glider large enough to carry a 10-year-old boy, and in 1853 he launched his coachman, John Appleby, across a valley on the first heavier-than-air flight by an adult.

When the glider landed, Appleby said, “Please, Sir George, I wish to give notice. I was hired to drive, and not to fly!”
