Britain packs an unusual amount of folklore into a small space. A fishing town in Fife, a moor in Yorkshire and a valley in Powys may be a few hours apart, yet each keeps its own creatures, its own names for them and its own rules about how to behave if you meet one. There is no single British fairy and no one official ghost dog.

These stories were local property. They belonged to a coastline, a hill, a bridge or a particular farm, and they still sit more comfortably in a village than in a book. Meet ten of the best-known creatures and the patterns start to show: what each one wants, what it punishes, and what it was probably invented to keep people away from.

Brownies: The Helper You Must Not Thank

A brownie is small, brown and hairy, and attaches himself to a household the way a cat does. In Scotland and the north of England he threshed the corn, cleaned the byre and tidied the hearth overnight, asking only for a bowl of cream or a bit of bread left out on the sill. He worked for no wages and wanted no fuss.

Then comes the rule that gives the story its sting. Offer a brownie clothes and you have insulted him: a linen shirt or a pair of breeches is a dismissal, and he leaves for good. Related spirits appear as the hob in Yorkshire and the Borders, the fenodyree on the Isle of Man and the bwca in Wales, though that last one is far less friendly.

The rules, in short

• Leave food, not money.
• Never offer clothing.
• Don't watch him work, and don't boast about him afterwards.

Boggarts and Bogles: When the House Spirit Turns

A boggart is what a brownie becomes when it has been offended, or simply when it has a bad temper and nowhere else to go. It is a Lancashire and Yorkshire creature, tied to a place — a field, a lane, a clough — and it hides tools, sours the milk and bangs about at night rather than helping.

A much-told story has a family moving house to escape theirs. They unpack, and the boggart is already there, or comes trundling up the road in the butter churn, announcing that they have merely changed address together. Bogle is the older Border word underneath it all, which is why we still have bogeymen; the Yorkshire barghest belongs nearby, though he prefers the shape of a dog.

Selkies: Seals Out of Their Skins

In Orkney, Shetland, the Hebrides and down the west coast, a seal could come ashore, step out of its skin and be a person. A man who found the hidden skin could keep the selkie wife with him, but only until she found it again — and in most tellings she does, usually years later, and returns to the sea without a backward look. Some versions have a child of theirs discover the skin while rummaging in the byre.

Male selkies come ashore too, and some tellings say they seek out women who have wept into the sea. What separates these stories from mermaid stories is that on land a selkie is entirely ordinary to look at. The other world is not under the water; it is the water, and the skin is the door.

Black Shuck and the Phantom Hounds

Black Shuck is East Anglia's great black dog: the size of a calf, shaggy, with one glowing eye or two, sometimes headless. To see him is usually an omen rather than an attack. In 1577 a printed pamphlet described such a dog bursting into St Mary's Church at Bungay during a thunderstorm, and the scorch marks on the door at nearby Blythburgh are still pointed out. That pamphlet was reprinted for centuries, and it did more than any other single text to fix Shuck in the English imagination.

Where else the dogs turn up

Phantom dogs are the most widespread creature in British folklore; almost every county has one. The Yorkshire barghest, the Welsh gwyllgi, the Moddey Dhoo of Peel Castle on the Isle of Man and the white, red-eared hounds of the Welsh Cŵn Annwn are all part of the same sprawling family. If a black dog guards a bridge, a churchyard or a stretch of road near you, you are in good company.

Kelpies, Water Horses and the Things in the Pond

The kelpie appears at the edge of a loch as a fine horse, saddled and patient. Anyone who mounts it finds their hands stuck fast to its hide and is carried into the water. In the Highlands the each-uisge does the same work with worse intentions, and the Welsh Ceffyl Dŵr is a water horse that may let you ride before vanishing in mid-air. Wales also has the Afanc, a lake beast that took a team of oxen and a fair bit of trickery to drag out of the water.

Lower down the scale are the hags of English ponds and rivers: Jenny Greenteeth and Peg Powler, with green teeth and a habit of pulling the careless under. Parents used them to keep children away from deep water and flooded banks, and in that job they were probably more effective than any fence.

Trows, Redcaps and the Northern Tricksters

The trows of Orkney and Shetland live in mounds, love music and dancing, and cannot bear daylight. Wander onto the wrong hill at dusk and you might be taken; a fiddler who plays too well for them may find himself invited back. Place names still carry them — a trowie knowe is a mound you leave alone.

The redcaps of the Borders and Northumberland are a different matter. They haunt old castles and pele towers, dye their caps in blood, and according to the stories cannot be outrun: once they start after you, you keep moving. The Hedley Kow of Northumberland is gentler. In the version most often told, a poor woman finds a fine cow that changes into a horse, then a sheep, then a dog, and finally a heap of straw. She carries the straw home for bedding anyway, and the Kow laughs and bounds away. The trick was real; so was the bedding.

How to Start Learning Them Properly

Folklore rewards slow reading. The creatures above will take you about a week to get straight, and years to know well.

• Anchor each story to a real place. A name on a map is a better memory hook than a description. Find your nearest boggart field, black dog lane or selkie shore and start there.
• Read the old county collections. Victorian and Edwardian folklorists wrote this material up county by county, and their volumes remain the starting point for most modern retellings. They are uneven, and they sometimes tidy the stories up, but they are the record.
• Watch the place names. Shuck, boggle, trow and hob all survive in field names, lanes and cloughs. An Ordnance Survey map is a folklore index if you read it that way.
• Collect versions and note the differences. Who dies, who gets the gold, whether the dog is an omen or a killer — the variations usually tell you who was telling the story and what they needed it for.
• Ask before you correct. If someone tells you their version, write it down as they gave it. Folklore is not a quiz with right answers.

Above all, don't demand belief — from yourself or from anyone else. These stories have always been told by people who half-believed them and enjoyed them anyway. That is the healthiest way to hold them: keep the milk out for the brownie, keep an eye out for the dog, and enjoy the fact that nobody has ever quite settled the argument.
