## Transcript

[0:04] Speaker 1: Welcome to Aaron Manke's Cabinet of Curiosities, a production of
[0:07] Speaker 1: iHeartRadio and Grimm and Mild.
[0:12] Speaker 2: Our world is full of the unexplainable, and if history
[0:17] Speaker 2: is an open book, all of these amazing tales are
[0:20] Speaker 2: right there on display, just waiting for us to explore.
[0:25] Speaker 2: Welcome to the Cabinet of Curiosities. There's nothing quite like
[0:37] Speaker 2: a desert island hypothetical. What movies would you take with
[0:41] Speaker 2: you to a desert island? Or albums, or in particular
[0:45] Speaker 2: who There are a million variations of the same question
[0:48] Speaker 2: that all boil down to one thing. What's important in
[0:51] Speaker 2: your life? What can't you live without? What these questions
[0:55] Speaker 2: don't really consider, though, is that desert islands aren't a
[0:58] Speaker 2: place that you bring your reality too. There are places
[1:01] Speaker 2: that create their own reality. Today, let's turn our focus
[1:05] Speaker 2: to Sable Island in the North Atlantic. If you're Canadian,
[1:09] Speaker 2: you might have heard of it, but for those who haven't,
[1:11] Speaker 2: it's a narrow stretch of island about ninety five nautical
[1:14] Speaker 2: miles southeast of Nova Scotia. From a satellite POV, it
[1:18] Speaker 2: kind of looks like a thin snake or a single eyelash.
[1:22] Speaker 2: The name comes from the French word for sand, and
[1:24] Speaker 2: it's easy to see why. The parts of the island
[1:27] Speaker 2: that aren't beach are covered in dry grass with no
[1:30] Speaker 2: native trees. Throughout the age of sail, shipwrecks on the
[1:34] Speaker 2: island were frequent, thanks to thick fogs and the island's
[1:37] Speaker 2: deceptive sandbars. It's estimated that up to three hundred and
[1:40] Speaker 2: fifty ships wrecked themselves on the island. The most recent
[1:43] Speaker 2: confirmed wreck was in nineteen forty one, although it's possible
[1:47] Speaker 2: some ships struck the island as recently as the nineteen nineties. Again,
[1:52] Speaker 2: looking at the shape of the island from above, it's
[1:54] Speaker 2: not hard to imagine it's like a tripwire designed to
[1:57] Speaker 2: catch unwary or unlucky vessel. But those shipwrecked sailors didn't
[2:02] Speaker 2: stay there. Those that survive often wind up getting taken
[2:05] Speaker 2: to the mainland of North America. The ones who did
[2:08] Speaker 2: stay behind there, Beside the gray seals that inhabit the beaches,
[2:12] Speaker 2: were around five hundred wild horses. Now we don't know
[2:16] Speaker 2: exactly where they came from, but most likely these horses
[2:19] Speaker 2: were introduced to the island in the mid seventeen hundreds
[2:23] Speaker 2: without any natural predators. They became the most influential population
[2:27] Speaker 2: on the island. For over two hundred and fifty years,
[2:31] Speaker 2: they've maintained a small but relatively stable population pun intended.
[2:36] Speaker 2: Other domestic animals.
[2:37] Speaker 1: Have also been brought to Sable Island, but none survived
[2:41] Speaker 1: quite like these horses. Survival for an animal on a
[2:44] Speaker 1: desert island is not easy. Water sources are sparse, and
[2:48] Speaker 1: the horses on the east side of the island have
[2:50] Speaker 1: to dig in the sand to create little wells for themselves.
[2:54] Speaker 1: You would never mistake a Sable Island horse for a
[2:57] Speaker 1: mainland horse. Their coats are thicker, shaggy aar and have long,
[3:01] Speaker 1: unkempt manes. Complete isolation from their more domesticated relatives has
[3:05] Speaker 1: made them a scientific marvel of sorts. They've experienced what's
[3:09] Speaker 1: known as a genetic drift away from the horses we
[3:12] Speaker 1: see in Europe and North America. Basically, they've almost become
[3:16] Speaker 1: a small subspecies of their own. And what's even more
[3:19] Speaker 1: fascinating is that these horses are more well adapted to
[3:21] Speaker 1: the environment than any plants that humans have attempted to
[3:24] Speaker 1: introduce there. At one point in the nineteen seventies, a
[3:27] Speaker 1: single Scots Pine was planted on the island by the
[3:30] Speaker 1: park rangers who maintain this station there. They decorated it
[3:34] Speaker 1: for Christmas, and it even survived for a number of
[3:36] Speaker 1: years before finally dying and returning the island to its
[3:40] Speaker 1: original treeless state. The horses themselves pose an interesting question
[3:44] Speaker 1: for conservationists. They're clearly an invasive species, but they are
[3:48] Speaker 1: incredibly valuable to understanding how species adapt to hostile environments
[3:53] Speaker 1: and how a single population of animals can gradually reshape
[3:57] Speaker 1: the same environment. Removing them would perhaps be good for
[4:00] Speaker 1: the biodiversity of the island itself, But since the horses
[4:04] Speaker 1: have been on the island for so long that ship,
[4:07] Speaker 1: so to speak, has sailed. There's no buried treasure to
[4:10] Speaker 1: be found on Sable Island in spite of the prodigious
[4:13] Speaker 1: number of shipwrecks. But in a way, the march of
[4:16] Speaker 1: history has left its own strange fingerprint all the same.
[4:20] Speaker 1: Who would have thought that feral horses could thrive on
[4:22] Speaker 1: a thin sandbar thirteen square miles in area. But that's
[4:26] Speaker 1: the thing about desert islands. They always bring out the
[4:29] Speaker 1: unexpected in all of us. When there's nothing but you,
[4:33] Speaker 1: the sand and the ocean. You either need to escape
[4:37] Speaker 1: or adapt. You've probably heard people say that laughter is contagious,
[4:54] Speaker 1: but that isn't always just a turn of phrase. On
[4:57] Speaker 1: a January morning in nineteen sixty to a teacher was
[5:01] Speaker 1: writing on the chalkboard at a girl's boarding school in
[5:04] Speaker 1: the African republic of Tanganika. She heard laughter behind her
[5:08] Speaker 1: and turned around to see three of her students giggling uncontrollably.
[5:12] Speaker 1: This wasn't unusual for a classroom full of teenage girls,
[5:16] Speaker 1: but when the teacher asked them to stop, they didn't. No,
[5:20] Speaker 1: they couldn't. Beneath their smiles, there was a spark of
[5:24] Speaker 1: fear in their eyes, as if their laughter truly was uncontrollable.
[5:29] Speaker 1: The teacher sent the girls to the principal's office and
[5:31] Speaker 1: got on with the lesson. But at the end of
[5:33] Speaker 1: the school day, when she passed by the nurse's office,
[5:36] Speaker 1: she saw those three students and two more girls, all
[5:39] Speaker 1: doubled over in their chairs, all still laughing, with tears
[5:43] Speaker 1: streaming down their faces. It was hard to tell whether
[5:46] Speaker 1: they were amused or agonized. Their laughter hadn't stopped the
[5:50] Speaker 1: following morning, In fact, it was spreading several more girls
[5:54] Speaker 1: in the same dormitory had to skip class that morning
[5:57] Speaker 1: because their laughter was so intense that they could barely
[6:00] Speaker 1: sit still. Each girl's laughing fit could last for anywhere
[6:03] Speaker 1: from a few hours to multiple days, and after they
[6:06] Speaker 1: had finally stopped giggling, some of them would start up
[6:09] Speaker 1: again just a few minutes later. Within a week, almost
[6:13] Speaker 1: one hundred students at the school were afflicted. There was
[6:15] Speaker 1: no end in sight, and the staff had no idea
[6:18] Speaker 1: what to do. The students had been examined by doctors
[6:21] Speaker 1: and nothing appeared to be physically wrong with them. It
[6:24] Speaker 1: had to be psychological, perhaps induced by stress. If this
[6:28] Speaker 1: was a subconscious ploy to get out of doing homework,
[6:31] Speaker 1: it was working. With more than half of the school's
[6:34] Speaker 1: students doubled over in laughter at any given moment, it
[6:37] Speaker 1: was impossible to conduct class, and when the madness still
[6:40] Speaker 1: hadn't died down by March, almost three months after it began,
[6:44] Speaker 1: the administration was left with only one option. They decided
[6:47] Speaker 1: to close the school and send everyone home until they
[6:51] Speaker 1: got their giggles under control, and that was a mistake.
[6:55] Speaker 1: The students went back to their home villages and they
[6:58] Speaker 1: spread the laughter up add throughout the entire region. Over
[7:02] Speaker 1: the next two months, around one thousand young people over
[7:05] Speaker 1: one hundred mile radius were afflicted by laughter. Fourteen schools
[7:10] Speaker 1: had to be shut down, and the school where it
[7:12] Speaker 1: all started was slapped with a lawsuit for sending everyone
[7:15] Speaker 1: home to transmit the contagion. The laughter came and went
[7:19] Speaker 1: in waves for the next year and a half until
[7:21] Speaker 1: it gradually died out in the summer of nineteen sixty three.
[7:25] Speaker 1: Order was restored and schools were reopened, but experts were
[7:29] Speaker 1: never able to explain exactly why this outburst happened. Some
[7:33] Speaker 1: researchers speculate that it was a case of mass hysteria.
[7:37] Speaker 1: Just a month before the laughter started, Tanganika had gained
[7:40] Speaker 1: independence from Britain, which began a period of massive social upheaval.
[7:45] Speaker 1: On a subconscious level, maybe the girl's laughter could have
[7:48] Speaker 1: been a way of releasing stress and coping with the
[7:51] Speaker 1: chaos and confusion. But at the end of the day
[7:54] Speaker 1: it backfired. After eighteen months of NonStop chuckling, everyone could
[7:59] Speaker 1: agree the joke just wasn't funny anymore. I hope you
