13 Secrets From the Ravenmaster at the Tower of London

Christine Colby

Christopher Skaife is a Yeoman Warder at the Tower of London, an ancient fortress that has been used as a jail, royal residence, and more. There are 37 Yeoman Warders, popularly known as Beefeaters, but Skaife has what might be the coolest title of them all: He is the Ravenmaster. His job is to maintain the health and safety of the flock of ravens (also called an “unkindness” or a “conspiracy”) that live within the Tower walls. According to a foreboding legend with many variations, if there aren’t at least six ravens living within the Tower, both the Tower and the monarchy will fall. (No pressure, Chris!)

Skaife has worked at the Tower for 11 years, and has many stories to tell. Recently, Mental Floss visited him to learn more about his life in service of the ravens.

1. MILITARY SERVICE IS REQUIRED.

All Yeoman Warders must have at least 22 years of military service to qualify for the position and have earned a good-conduct medal. Skaife served for 24 years—he was a machine-gun specialist and is an expert in survival and interrogation resistance. He is also a qualified falconer.

Skaife started out as a regular Yeoman Warder who had no particular experience with birds. The Ravenmaster at the time "saw something in him," Skaife says, and introduced him to the ravens, who apparently liked him—and the rest is history. He did, however, have to complete a five-year apprenticeship with the previous Ravenmaster.

2. HE LIVES ON-SITE.

As tradition going back 700 years, all Yeoman Warders and their families live within the Tower walls. Right now about 150 people, including a doctor and a chaplain, claim the Tower of London as their home address.

3. BUT HE’S HAD TO MOVE.

Skaife used to live next to the Bloody Tower, but had to move to a different apartment within the grounds because his first one was “too haunted.” He doesn’t really believe in ghosts, he says, but does put stock in “echoes of the past.” He once spoke to a little girl who was sitting near the raven cages, and when he turned around, she had disappeared. He also claims that things in his apartment inexplicably move around, particularly Christmas-related items.

4. THE RAVENS ENJOY SOME UNUSUAL SNACKS.

The birds are fed nuts, berries, fruit, mice, rats, chicken, and blood-soaked biscuits. (“And what they nick off the tourists,” Skaife says.) He has also seen a raven attack and kill a pigeon in three minutes.

5. THEY GET A LULLABY.

Each evening, Skaife whistles a special tone to call the ravens to bed—they’re tucked into spacious, airy cages to protect them from predators such as foxes.

6. THERE’S A DIVA.

One of the ravens doesn’t join the others in their nighttime lodgings. Merlina, the star raven, is a bit friendlier to humans but doesn’t get on with the rest of the birds. She has her own private box inside the Queen’s House, which she reaches by climbing a tiny ladder.

7. ONE OF THEM HAS EARNED THE NICKNAME “THE BLACK WIDOW.”

Ravens normally pair off for life, but one of the birds at the Tower, Munin, has managed to get her first two mates killed. With both, she lured them high atop the White Tower, higher than they were capable of flying down from, since their wings are kept trimmed. Husband #1 fell to his death. The second one had better luck coasting down on his wings, but went too far and fell into the Thames, where he drowned. Munin is now partnered with a much younger male.

8. THERE IS A SECRET PUB INSIDE THE TOWER.

Only the Yeoman Warders, their families, and invited guests can go inside a secret pub on the Tower grounds. Naturally, the Yeoman Warder’s Club offers Beefeater Bitter beer and Beefeater gin. It’s lavishly decorated in police and military memorabilia, such as patches from U.S. police departments. There is also an area by the bar where a section of the wall has been dug into and encased in glass, showing items found in an archaeological excavation of the moat, such as soldiers’ discarded clay pipes, a cannonball, and some mouse skeletons.

9. … AND A SECRET HAND.

The Byward Tower, which was built in the 13th century by King Henry III, is now used as the main entrance to the Tower for visitors. It has a secret glass brick set into the wall that most people don’t notice. When you peer inside, you’ll see it contains a human hand (presumably fake). It was put in there at some point as a bit of a joke to scare children, but ended up being walled in from the other side, so is now in there permanently.

10. HE HAS A SIDE PROJECT.

Skaife considers himself primarily a storyteller, and loves sharing tales of what he calls “Victorian melodrama.” In addition to his work at the Tower, he also runs Grave Matters, a Facebook page and a blog, as a collaboration with medical historian and writer Dr. Lindsey Fitzharris. Together they post about the history of executions, torture, and punishment.

11. THE TOWER IS MUPPET-FAMOUS.

2013’s Muppets Most Wanted was the first major film to shoot inside the Tower walls. At the Yeoman Warder’s Club, you can still sit in the same booth the Muppets occupied while they were in the pub.

12. IF YOU VISIT, KEEP AN EYE ON YOUR MONEY.

Ravens are very clever and known for stealing things from tourists, especially coins. They will strut around with the coin in their beak and then bury it, while trying to hide the site from the other birds.

13. … AND ON YOUR EYES.

Skaife, who’s covered in scars from raven bites, says, “They don’t like humans at all unless they’re dying or dead. Although they do love eyes.” He once had a Twitter follower, who is an organ donor, offer his eyes to the ravens after his death. Skaife declined.

15 Secrets of Commercial Divers

Imagine some of the most physically demanding jobs available—supply line installation, construction, welding—and then imagine doing them underwater. That’s the life of a commercial diver, a rigorously trained professional who undertakes everything from bridge repairs to oil line maintenance. To get a better sense of this often difficult and dangerous work, Mental Floss spoke to several commercial divers for their thoughts on everything from the perils of decompression to swimming in sewage. Here’s what they had to say about a life in flippers.

1. DIVING DEEP CAN PRODUCE EUPHORIA (AND A WEIRD VOICE).

Commercial divers receive specialized training—either in the military or at diving instructional schools—to learn how to function hundreds of feet below the surface. The lower a diver goes, the more water pressure increases, and the greater the challenges. Jeremy, a commercial diver out of Louisiana who repairs and installs equipment for oil companies, says that working in such conditions can lead to physical exhaustion, pulled muscles, and a feeling of pressure on the lungs.

Plunging to a depth in excess of 100 feet can also result in nitrogen narcosis, which some refer to as "raptures of the deep" or the "Martini effect." It's caused when divers receive a higher concentration of nitrogen from their air supply due to the effects of the water pressure on the gas. (The air systems that commercial divers use allow them to breathe normally by providing air at a pressure equal to that of the water, but the lower they go, the denser the gas gets, and thus the higher the concentration.)

“It makes you feel drunk or euphoric,” Jeremy says of the narcosis. “The solution is to switch from a nitrogen-oxygen supply to helium and oxygen.” That cures the over-inhalation of nitrogen, but when a diver comes back to the surface or to a decompression chamber, their voice will be altered. “It’s an Alvin and the Chipmunks thing,” Jeremy explains. Some diving teams will use voice augmentation to de-scramble the high-pitched squeals when divers are communicating with the surface.

2. ABOUT HALF A DOZEN OF THEM DIE EACH YEAR.

Most commercial diving is centered around underwater construction—often repairing or replacing infrastructure that facilitates water, oil, or electrical supplies. Divers are frequently charged with digging trenches to bury electrical lines using high-pressure water blasts to excavate the ocean floor. If these trenches collapse, it can result in a catastrophic situation; the cave-in can trap and bury a diver, clogging their regulator or causing them to take off their helmet in a panic, which eliminates their air supply. Jeremy says a number of divers die every year in such cave-ins.

If divers can avoid that fate, they still have to worry about a number of other ways they can meet an untimely end. “We use cranes and those can fall or drop their load on you,” Jeremy says. Cutting into “live” pipelines can also cause explosions, as can using tools that displace hydrogen from the water. In an enclosed space like a ship or supply pipe, that collected hydrogen could catch a spark and explode. “That could blow your helmet off or into pieces,” he says. All in all, 25 commercial divers died on the job between 2011 and 2014, according to the Bureau of Labor Statistics; another 310 suffered nonfatal injuries or illnesses.

3. THE DEEPER THEY GO, THE MORE THEY EARN.

Diving jobs vary in pay according to risk, duration, and other variables, but generally, a diver’s base pay is usually supplemented with “depth pay.” The further down they go, the more they can make.

“It’s basically about a dollar a foot,” Jeremy says. “After 150 feet, the price can double to $2 a foot. Added on to regular pay, a 12-hour day can add up.” A diver working at 300 feet might net $1000 in a shift. Saturation divers, who can go 1000 feet down and are required to live off-shift in a chamber pressurized to the surrounding water in order to avoid decompression sickness, or the “bends,” can make even more.

4. SOMETIMES THEIR SUITS ARE HEATED.

Going deeper into the water means enduring more frigid conditions. To offset plummeting temperatures, divers need a way to keep their suits warm. “Below 80 feet, it gets cold,” Jeremy says. “We either pump water into a wet suit or wear a hot-water suit.” The former allows water to come in and make contact with the diver's body, typically from a heated source at the surface; the latter has water channels throughout the suit that branch out and keep divers from getting too cold. Because hot water suits can maintain a more consistent temperature than delivering warm water from above, they are most often used at 200 feet and lower depths.

5. THEY CAN WIELD FIRE UNDERWATER.

Most tools meant for underwater use are hydraulic (involving the use of water or other liquids), since they’re largely unaffected by water pressure. Fuel-powered or pneumatic tools (those that involve the use of gas) don’t really work, but divers can still make use of jackhammers, chainsaws, and other devices you’d find in an above-ground construction job. Others, however, need to be adapted.

“In my opinion, the most interesting adaptation is the BROCO torch,” says Brian, a diver based in New England. The BROCO torch uses direct current to ignite a magnesium rod and oxygen mixture that burns at approximately 10,000 degrees and can cut through metal like butter, even underwater. (A/C, or alternating current, is what we use in our homes—but because the direction of the current reverses many times a second, Brian explains, it can freeze the diver in place while electrocuting them, making it too dangerous for underwater use.)

6. THEY MIGHT FIND DEAD BODIES.

According to Jeremy, many recovery dives for people suspected of drowning fall under the purview of local law enforcement. Still, commercial divers can encounter someone who’s wound up in a watery grave. “I’ve done helicopter recovery jobs,” he says, referring to crashed aircraft that can harbor passengers. Once, while working on an oil rig, he stumbled upon a dead scuba diver. “It was more of a skeleton in a scuba suit,” he says. If a diver does find a corpse, they're unlikely to ever know the history of how the body got there; such discoveries are required to be passed on to the Coast Guard for investigation.

7. THEY CAN WIND UP FEEDING FISH.

“We encounter marine life all the time,” says Mike, a commercial diver who now works primarily in and around the Great Lakes. “When working the ocean, if we are cleaning off marine growth, sometimes you will get some fish that come up and eat what you are cleaning off.” Mike says that commercial divers frequently spot sharks, barracudas, and other potentially dangerous sea dwellers, but the animals generally don't care much about humans. They’re even less likely to approach if the workers are using torches.

8. THEY SOMETIMES SWIM IN UTTER FILTH …

A common component of commercial diving, HAZMAT (hazardous material) diving involves working in contaminated water. That could mean anything from a lake affected by nearby lawn chemicals to checking equipment at a nuclear reactor. If it could kill or poison you, a diver has probably swum in it.

This kind of work requires a special approach. Brian says that those who venture into higher-risk HAZMAT diving usually wear a positive pressure diving helmet; since the pressure inside the helmet is greater than the pressure in the water outside, the helmet helps keep hazardous material from entering. HAZMAT divers also wear a rubber dry suit that fully seals the diver's entire body, unlike normal wet suits, which allow water to make contact with the wearer. Support staff will also decontaminate the HAZMAT diver after the job, scrubbing their suit free of harmful materials before the diver undresses.

9. … INCLUDING SEWAGE.

Those stories you may have heard about people diving into sewage treatment plants to repair equipment? Those would be commercial divers, who occasionally brave the psychological challenge of being submerged in poop. Because it's usually impossible to see in a sea of feces, divers will study reference photos of empty tanks before going in. They'll suit up in sealed dry suits and typically will weigh themselves down in order to sink through the dense liquid; once they're in position, they work by feel. “Both the sewage jobs I dove on, it was repairing a masticator blade,” Mike says. “Picture a giant blender that makes solids less solid. I don't do it anymore because of the health risks.” A rip or tear in a diver's suit can introduce a litany of dangerous bacteria into their body: In addition to your standard Salmonella and Cryptosporidium parasites, such vile muck can also harbor hepatitis, Norwalk virus, E. coli, and assorted fungi [PDF].

10. DAWN SOAP IS A LIFESAVER.

Dawn dishwashing liquid is a must-have on diving expeditions. It can get diving suits and skin free of oil, and can even help divers cope with parasitic pests. When Jeremy was working on a mile-long pipeline near New Orleans, the shallow water resulted in workers getting infested with parasites carried by nutria, a semiaquatic rodent. “The hookworms will dig into your skin, die, and leave a big red mark,” he says. Splashing Dawn soap gets rid of the itch immediately. (If irritation persists, divers might need to seek anti-inflammatory treatment from a dermatologist.)

11. THEY WORRY ABOUT BEING SUCKED INTO A VACUUM OF DEATH.

Divers are frequently in violation of the laws of nature. Humans, after all, were never meant to thrive (or survive) underwater, particularly at more pressurized depths. Many divers fear encountering Delta P, or differential pressure—a vacuum that’s far higher in pressure than their current environment, and is created by intersecting water bodies as a result of opening a channel like a pipe. “Delta P is vacuum-like suction much like you would imagine from when the cabin of an airplane ruptures, but at a much greater magnitude,” Brian says. “It can be very difficult to detect until you are already too close, and can trap the diver at depth or even kill them instantly.” The unfortunate crab in the video above is an example of how differential pressure can ruin your day.

12. THEY SOMETIMES GO DIVING INSIDE WATER TOWERS.

Those water towers you see in populated areas that stand on stilts hundreds of feet up in the air? Townships need to periodically check them for sediment levels to maintain water quality. That’s when they call in a commercial diver, who needs to add "not afraid of heights" to their skill set. “You have to climb all the way up, get into your wet suit, measure the sediment with a ruler, and clear it out with a [suctioning device called an] airlift." Jeremy says. And that's not the only lofty prospect for a diver: Jeremy notes that some oil rigs stretch 100 feet in the air. Divers without seniority may be expected to carry out repairs or work at or near the top, instead of actually diving.

13. THEY CARRY KNIVES.

No, it’s not to duel with sharks. “While diving, I carry a razor-sharp knife for emergency purposes only,” Brian says. In an urgent situation, it could be used for "cutting anything from old fishing line to my own dive umbilical—the air hose and lifeline.” The latter rarely happens, unless the diver gets it snagged or it becomes compressed. In the event of a hose failure, divers have a "bailout bottle," a supplemental tank they can switch to in case of emergency.

14. THEY CAN BE UNDERWATER BUT NOT ACTUALLY IN THE WATER.

Not every dive requires divers to swim while working. For jobs that require meticulous attention to detail for repair or where welding is required, diving teams can set up positive pressure habitats that isolate the problem area and allow the diver to work out of water. “You use air pressure to push water out of the habitat, which is in two pieces,” Jeremy says. Inside, a diver would trade their helmet for a welding mask. Because it can take a day or more to set up the habitat for a job that might take only one or two hours, habitat work is used only in cases where there aren't any other options.

15. THEY STILL GO SWIMMING FOR FUN.

Like anything done recreationally, diving can begin to seem routine if it's performed on a daily basis. While some divers get their fill of water by working 12-hour days for weeks at a stretch, some still enjoy going under in their free time. “While my career has definitely diminished the novelty of being in such an alien environment, I still love to dive recreationally,” Brian says. “Commercial diving is exhausting work, typically in dark, low-visibility water with a particular task in mind, while recreational diving is often more about exploration and sight-seeing. I would argue that the difference is not unlike a professional runner going on a beautiful hike in their free time.”

11 Secrets of Romance Writers

Some readers may snicker at book covers featuring aerobicized men and titles like The Firefighter’s Woman or The Bull Rider’s Christmas Baby. But if it weren’t for the steamy, escapist fantasy of romance novels, a healthy portion of the publishing industry would cease to exist: According to the Romance Writers of America (RWA), romantic fiction brings in $1.08 billion annually and accounts for 13 percent of all fiction sales in the marketplace.

What keeps readers coming back for more? We asked some of the genre’s top authors for insight into the “secret baby" trope, why pen names are necessary, and the one rule of romance that can never, ever be violated.

1. THEY WEAR PERIOD CLOTHING.

Novelist Shelley Adina (A Lady of Resources, A Lady of Integrity) writes historical, Amish, and steampunk-themed fiction, just a few of the many sub-categories that appeal to niche audiences. To better understand her characters, Adina dresses in period outfits to gather what she calls “tactile details.”

“I like to feel how a heroine would feel in the clothes,” she says. “I’ve been laced into a proper corset and you realize what kind of dance steps you can do, or why a lady’s back never touches a chair—a tight corset won't allow it."

2. THE REASON THEY USE PEN NAMES ISN'T WHAT YOU THINK.

The authors of romance novels don't use pen names out of embarrassment. Adina (a.k.a. Adina Senft) says that pseudonyms—many authors have more than one—help readers compartmentalize writers who generate multiple series. “People who read Amish fiction may not read steampunk,” she says. Another, bigger reason: Bookstore software can use “kill orders” on authors who don’t sell a certain number of titles. If they fall below parity, retailers will automatically stop ordering more copies from that author. “If that happens,” she says, “you have to reinvent yourself with a new name.”

3. THEY’LL DIGITALLY REVISE THEIR WORK AFTER PUBLISHING IT.

The analog publishing model has traditionally been one of permanence: Once a book is in print and in readers' hands, there's no going back. But romance novel readers are a very particular clientele with certain expectations about how they’d like their protagonists to behave—and the self-published digital distribution model that's popular within the genre allows for a little customization. Author Heather C. Leigh (the Famous series) found that out when her first books featured a heroine who was a little too acerbic. “My first three books sold well, but there were critiques that my female lead was too sarcastic,” she says. “I understood and took it out. I don’t mind making work better based on feedback.”

4. COVER MODELS OFTEN LOSE THEIR HEADS.

Despite seeing hundreds of new titles published every month, the romance genre still manages to find new ways to visualize their shirtless male protagonists. In many cases, though, the beefcake winds up getting decapitated. “A lot of times, the man will be turned away or cut off at the forehead,” says author Eliza Night (The Conquered Bride series). “Readers want to imagine his looks in their own mind.” Grooming is also a necessity. “I had a cover with chest hair once. My readers did not like it.”

5. THEY HAVE BONUS SCENES.

Self-published authors (who make up about two-thirds of the total romance e-book revenue on Amazon) spend much of their time marketing their work. To help maintain interest from their existing readership, some send out email newsletters with updates on new titles and include exclusive passages that can enhance the experience of a previous book. “My first book was about an actor who had to do a love scene with a woman he hated,” Leigh says. “It was never going to be in the book because that was from his girlfriend’s point of view, but I got a chance to write it as a bonus.”

6. THEY WANT READERS TO BECOME WRITERS.

While resources for aspiring writers of all genres are plentiful, the romance field makes an exceptional attempt to recruit new talent. Industry interest group RWA doubles as a conduit between established writers and novices, hosting conferences and panels on the best ways to break in. “We don’t live in a competitive hierarchy,” Adina says. “There are so many readers with so many diverse tastes. It’s a big community where we support one another.”

7. THEY GET HELP FROM THE AMISH.

While the Amish sub-genre has received media attention for its peculiarity, Adina doesn't believe it's so unusual: She says readers are attracted to a pastoral environment “without having to leave their wired-up house.” For accuracy’s sake, the author has enlisted an Amish reader to vet her titles for details. The popularity of the books “mystifies them,” she says. “They don’t understand the interest. They just hope the books might be able to point people to God.”  

8. THE “SECRET BABY” TROPE IS A READER FAVORITE.

Readers like resourceful women and skilled, wealthy love interests—and they especially like it when the former keeps their baby a secret from the latter. “The trope is that the hero and heroine have an affair, she gets pregnant, never tells him, and he comes back around five, 10, or 20 years later and finds out,” Adina says. “Reunion stories are popular. It’s the appeal of a responsible man.”

9. THEY’RE HISTORY GEEKS.

Knight cringes at the idea romance authors do little more than transcribe their own lurid fantasies. A self-described “history geek,” she travels frequently for research into Scottish history. “Most of us who write history nerd out on it,” she says. While once writing about a zeppelin-riding heroine, Adina jumped into one that offered rides over Silicon Valley to see how it would feel. She also got her motorcycle license for the same reason. “We’re serious about it,” Adina says. “We’re not sitting around in housecoats with barking Pomeranians.”

10. THEY’D APPRECIATE NOT BEING ASKED ABOUT THEIR SEX LIFE.

Many romance authors have at least one story to tell about people in their private life finding out they write for the genre and subsequently losing any sense of boundaries. “Strangers have asked me, ‘Do you test out scenes before you write them?’” Leigh says. “It’s like they lose a filter. It’s not real life. J.K. Rowling isn’t a wizard.”

11. THERE’S ONE RULE THAT CAN NEVER BE BROKEN.

While writing instructors invariably have all kinds of techniques for nourishing a story, the romance genre spells it out in an unequivocal manner. According to the RWA, nothing can be considered a “romance novel” without a central love story (naturally) and what authors have come to refer to as the Happily Ever After ending, or HEA. “Romance is a courtship story,” Adina says. “Readers expect the bond will be created at the end of the book. If not, it’s Nicholas Sparks or Romeo and Juliet. It would be like having a mystery where the detective doesn’t solve the case.”
