Why Early America Was Obsessed With Wooden Nutmegs

Original image

Although today we’re primarily familiar with nutmeg as a powder that comes in little plastic bottles, it’s actually the pit of the fruit of a tree native to the Banda Islands of Indonesia. Throughout the 18th century, the Dutch controlled the Banda Islands, keeping nutmeg scarce and prices high in international markets. In America, where nutmeg was a popular flavor in 18th and early 19th century cooking, the spice was extraordinarily expensive—so expensive, unscrupulous vendors allegedly tried to replicate nutmegs in wood.

At the time, America’s rural communities were connected by a network of itinerant peddlers, or “hucksters,” who sold household goods. The peddlers were often associated with dishonest dealings (part of the definition of a “huckster” today), and the original “wooden nutmeg” was a euphemism for a general mistrust of such people. Thomas Hamilton, a British traveler who toured America and documented his findings in Men and Manners of America in 1833, said of peddlers in New England: “They warrant broken watches to be the best time-keepers in the world; sell pinchbeck trinkets for gold; and have always a large assortment of wooden nutmegs and stagnant barometers.” In The Clockmaker: Or, The Sayings and Doings of Samuel Slick, of Slickville, published in 1839, the main character is called “a Yankee pedlar, a cheatin vagabond, a wooden nutmeg” by an incensed rival.

But were wooden nutmegs real, or a myth used to villainize merchants? In appearance, weight, and texture, nutmegs are very similar to wood. Curious about the practicalities of carving one, I commissioned an artist to make me a wooden nutmeg to see if the time and craftsmanship involved were worth the monetary gain and risk of getting caught. He produced a convincing nutmeg in 30 minutes, which would have been especially realistic if it had been lightly colored with a natural stain. The artist estimated it would have taken him an hour if he eliminated the use of a bandsaw and belt sander for the earliest steps in shaping the nutmeg, and relied only on hand tools available in the 19th century. Although it's difficult to estimate early-19th-century work weeks and salaries with precision, a laborer in the early 19th century might have made about $.08 an hour (based on an average daily salary of about $1 and a 12-hour workday) [PDF]. I’ve estimated that a nutmeg would sell for about the same amount as that hourly wage, based on references I’ve found to British prices at the same time and American prices later in the century. That means the labor may have been worth it.

However, as a consumer it would have been easy to foil a fake nutmeg vendor: A purchaser could take a small nutmeg grater with them and grate a little of the nutmeg before buying. Either the grated nutmeg would release its signature spicy smell, or the wood would be largely odorless—a clear sign of a fake. But perhaps if the fake nutmegs were mixed in with real ones (as one early reference to the story suggests), the scheme could work—especially if the seller wouldn’t be passing that way again.

In the decade before the Civil War, the wooden nutmeg also became symbolic of the heightening tensions between the urban, liberal North and the rural, conservative South. In the Southern version of the story, Northerners are painted as devious fraudsters. For example, an algebra textbook published by a North Carolinian in 1857 offers this problem: “A Yankee mixes a certain number of wooden nutmegs, which cost him 1/4 cent apiece, with a quantity of real nutmegs, worth 4 cents apiece, and sells the whole assortment for $44 and gains $3.75 by the fraud. How many wooden nutmegs were there?” The same year, The National Magazine quoted a Northerner who said, “I would rather come from that part of the country where the people make wooden nutmegs than to come from that part of the country where the people are fools enough to buy them.”

Although all the wooden nutmeg stories refer to the peddlers as simply “Yankees,” it was in this era that Connecticut unofficially took on the moniker of the Nutmeg State. According to an 1859 source, the nickname was adopted because of the stories that wooden nutmegs “are manufactured there.” It Happened in Connecticut author Diana McCain posits the nickname was adopted much like Yankee Doodle—transformed from an insult into a proud rallying cry.

Soon after the Civil War, stories of wooden nutmegs passed into history and legend. In 1801, the British invaded and temporarily gained control of the Banda Islands. One of their first actions was to remove nutmeg trees and transplant them to other British colonies, including Grenada in the Caribbean—where much of the world’s nutmeg comes from today. Nutmeg prices dropped dramatically by the middle of the 19th century, and dominated the flavors of American food in the 1840s to 1860s. According to the Oxford Encyclopedia of Food and Drink in America, 17 mechanical nutmeg graters were patented between 1854 and 1868, an example of nutmeg’s immense popularity and availability.

Now that nutmegs were cheap and plentiful, the era of the wooden nutmeg was over—if it had ever existed at all. An edition of the magazine The Ladies Repository published in 1865 tells one more version of the origin of the story: A fool from South Carolina bought real nutmegs, and upon trying to crack them with a nutcracker, found there was no meat inside. He then accused the seller of selling him fake nuts made from wood. In this case, the magazine framed the narrative as a Northerner versus a Southerner, but the story feels like one that predates Civil War politics, retold and reframed many times. Perhaps all the cautionary tales, insults, and rivalries were spawned not by actual wooden nutmeg trickery, but simply by an oft-repeated joke.

Today, saffron, vanilla, and cardamom are the most expensive spices on the planet—not nutmeg. Because such spices are often hard to grow and labor-intensive to harvest, it’s not uncommon for them to be replaced by cheaper alternatives, like safflower for saffron and artificially produced vanillin for vanilla. Some spices might also be adulterated with cheaper ingredients—oregano can be bulked up with sumac leaves—while others are dyed to improve their appearance. Both methods increase profit margins. But in the 21st century, it’s rare to find the outright brazen fraud of the wooden nutmeg.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!
