The story of Lukki Minnie

Malachy shares a piece of Fair Isle folklore introducing us to the Trow.

For centuries – perhaps even for millennia, no-one is entirely sure – Shetland has been home to a very special creature. It is rarely seen these days, but it nevertheless inhabits a special place in Shetland culture and history. It is the trow.

Similar in many ways to Scandinavian trolls or Irish leprechauns, the most significant difference between Shetland trows and their folkloric cousins is that trows really exist.

Most places in Shetland have their own trow stories, but while many of them involve trickery, mischievous behaviour, and even the occasional kidnapping, few are quite as sinister as the tale of Fair Isle’s most famous trow: Lukki Minnie.

The story of Lukki Minnie’s downfall is known to all Fair Islanders, and although everybody’s version differs slightly, the essence of all of them is the same. As I remember it, the story goes like this . . .

A young boy – possibly named Willie – was out playing one afternoon on the hill called Malcolm’s Head, in the south-west of the island. He was rolling a large bannock (similar to a scone) that his mother had baked, pushing it down the steep slope and racing after it towards home.

Suddenly, the bannock disappeared, and the boy stopped dead. He saw at once that it had fallen down a hole, but he wasn’t quite sure what kind of hole it was. It was bigger than a rabbit hole, but was well hidden amongst the grass and heather. In fact, it was just big enough for him to squeeze through, which is exactly what he did. But he very quickly regretted it.

Something had grabbed hold of his shoulders and was hauling him in. He tried to pull himself back out again but he couldn’t manage, and all at once he found himself lying on the floor of a small dark room, like a cave. The only light in the room came from a peat fire in the centre, but even in that flickering gloom he could see at once that the horrible creature in front of him was Lukki Minnie.

He wanted to run but there was nowhere to go. He wanted to shout but there was no-one to hear him. He was completely stuck.

Lucki Minnie grabbed hold of the boy and she stuffed him roughly inside a sack, which she then hung up close to the fire. He could feel the heat of the flames as he hung there, and he knew she was planning to eat him.

Later that night, when everything was quiet, Willie took his chance to escape. He drew his penknife out from his pocket and quickly cut through the sack. He climbed out and ran towards the hole in the ceiling, through which he’d first arrived. But before he could get away, he heard Lukki Minnie returning home. He had to think quickly.

Willie grabbed hold of the little dog which had been sleeping by the fire, and he shoved it inside the sack, along with some crockery from the sideboard. He tied it up and hung it on the hook again, and then hid behind the door to wait.

Lukki Minnie came in with her pockets filled with potatoes and carrots. She was ready for her dinner.

“A’m gyaan ta aet dee noo” she shouted. “Bit furst A’m gyaan ta mak dee gud and saft.”

She took out a big, heavy stick from beside the fire and started to beat the sack as hard as she could. The plates inside began to crack.

“Ah can hear dy banes brackin,” she shouted.

Behind the door the boy was giggling quietly to himself. Inside the bag, the dog was yelping.

“Ah can hear dee yowlin, boy” said the trow, with a big grin on her face.

Willie was so pleased with his trick that he couldn’t help himself. He laughed and laughed so loudly that Lukki Minnie finally heard him. She spun around, her eyes blazing with anger. She knew at once what had happened.

Willie recovered quickly and darted up and out of the hole, back on to the hill he knew so well. In the pale light of the evening he could still make out the shape of his house, less than half a mile away. But the trow was close behind.

“A’m gyaan ta git dee” she screamed, as he fled down the hill towards safety. He didn’t dare to turn around.

When he reached the burn that runs along the bottom of Malcolm’s Head, Willie jumped. He sailed through the air and landed on the opposite bank, panting heavily. A second later, Lukki Minnie jumped after him. But trows’ legs are short, and she didn’t make it.

Lukki Minnie landed in the burn and was swept downstream towards the sea at Hesti Geo. Willie stood and watched her disappear, until he was sure she was gone. Then he turned and ran back home to tell the tale.

Today, when the wind blows strong from the south-west, Hesti Geo fills with thick, dirty-white scum, that blows up and over the land at the bottom of the hill. “Lukki Minnie’s still in there, churning her butter,” people say. And perhaps she is.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
