A lime-white lighthouse tower on a low headland at night, its warm beam cutting out over dark water into low cloud.

You sleep in the house of a light that no longer needs anyone.

It still flashes twice every twenty seconds, and in the west bedroom it still crosses the ceiling. Rubha na Fàire, Wester Ross: manned for a hundred and thirty-one years, and let by the week since.

A ship does not recognise this light. It counts it.

Every light in the world is given a rhythm nobody else nearby is allowed to have. Ours is two flashes every twenty seconds. That sequence, not the colour or the brightness or the position, is how anyone at sea knows which light they are looking at.

Rubha na Fàire, character Fl(2) W 20s: 2 flashes every 20 seconds, drawn to true scale.05101520

One full period, to true scale in seconds. The lit blocks are the flashes; all the rest of it is eclipse.

Four lights you can see from this headland

Three of them run on the same twenty seconds as ours. Watch any one of them and you will see why counting is the only method there is.

Ours. Two flashes, then sixteen and a half seconds of nothing — the long eclipse is what you actually learn to feel.

And then: how far does it actually reach?

Not as far as the published figure, for almost anyone. Brightness is only half of it. The earth curves away underneath, and below a certain eye height that is what decides the answer.

A section over the curve of the earth. From an eye height of 2 metres the horizon is 2.9 nautical miles off, and a light 39 metres high goes under it at 15.9 miles. The lamp itself is bright enough for 24 miles.2 mfàire · horizon 2.9 M39 man lampa 24 Man saoghal 15.9 MVertical scale exaggerated about forty times.

The lamp is bright enough for 24 M. From a yacht cockpit the earth hides it at 15.9 M — 8.1 miles short of the published range. What you see first is the loom of it on the cloud, not the light.

2.08 × (√H + √h), H the height of the light and h the height of your eye, both in metres, giving nautical miles. It is the whole of the calculation and it has not changed since it was first printed.

The machine that makes the rhythm.

The lamp does not blink. It burns steadily and the glass goes round it, and everything else in the tower exists to keep that turning, keep it clean, and keep it alight. Nine points into it.

A large Victorian Fresnel lighthouse lens: concentric rings of ground glass prisms in a brass frame, lit warmly from within.
An lionsa. Two panels of glass, and that is the whole of why the character is two flashes. The lamp inside never stops.

There are no curtains in the west bedroom.

We will not be fitting any. Every twenty seconds a band of light crosses the ceiling from the window to the door, and it is the reason to come.

The principal keeper's house: two bedrooms, a sitting room facing the tower, a kitchen with the original solid-fuel range, and a store that still smells of paraffin a hundred years after the last drum left it. Walls six hundred millimetres thick. Sleeps four.

Most people take two nights to stop noticing the light and then miss it when they go home. That is the most consistent thing anyone says in the book by the door.

A whitewashed bedroom at night with an iron bedstead and a deep-set window, a band of warm light thrown across the ceiling by the lighthouse beam.
An seòmar-cadail. The beam passes over the roof, not through the room — what crosses the ceiling is the light going out to sea.

The station. Two houses, the tower, a walled garden that has never grown anything, and a jetty in the only landing on this side of the point.

Somebody was awake here every night for a hundred and thirty-one years.

Then on the fourth of October 1988, at ten past three in the afternoon, nobody had to be. The light did not change. That is the whole of what changed.

Iain MacAulay

The last principal keeper

Came to the station in 1971 and kept the watch until the fourth of October 1988. Lives eleven miles away and has never once asked to come back up the tower.

“It wasn’t the dark you noticed. It was that something had to be done every half hour, all night, for a hundred and thirty-one years, and then on a Tuesday afternoon it didn’t.”

Mòrag NicLeòid

Attendant

Services the light four times a year: lamp changer, charge controller, seals, and the outside of the panes. Twenty-one stations on her round, from Ardnamurchan to the Summer Isles.

“People think it’s romantic. It’s a bulb, a battery and a lot of salt. But if I get it wrong somebody finds out about it at two in the morning in a Force 8.”

Dòmhnall Grant

Boat

Brings guests, coal, gas and everything else in from the village when the track is out, which is about nine weeks a year. Forty minutes each way, and he will not go in a southwesterly over 6.

“If I say no, it’s no. I’ve had folk offer me two hundred pound to try it and the answer is still no.”

Taking the week.

Saturday to Saturday. We will write back with what the track is doing and whether you need Dòmhnall, and that reply is worth waiting for before you book anything else.

An seusan the season

The price is the week. What actually differs is how much dark you get.

A Saturday. If it is not a Saturday we will move it to the nearest one and tell you.

Give us a date to look at, even an approximate one.

We need a name for the book by the door.

That address will not take a reply. Check it and send again.

The last four miles are single track, unsurfaced and ungritted. It matters more than anything else on this form.
