INTRODUCTION The marvellous
Sound of Mull, summer 2020.
The sea is not made of water. Creatures are its genes. Look down as you crouch over the shallows and you will find a periwinkle or a prawn, a claw-displaying crab or a cluster of anemones ready to meet you. No need for binoculars or special stalking skills: go to the rocks and the living will say hello.
In the 1850s, when Victorian Britain fell in love with the seaside, the rock pool became the heart of a kind of nature- worship which saw in its riches and calm a reassuring vision of creation. Life in what Philip Henry Gosse, the great apostle of the pools, called ‘these unruffled wells’ was a gathering of goodness and even happiness. It was as if the pools came from a time before the Fall, when life was innocent and unthreatened. Gosse, surely half-remembering the children’s rhyme, imagined ‘Adam and Eve, stepping lightly down to bathe in the rainbow-coloured spray.’ At just the moment Darwin was challenging the God-ordained vision of nature, and setting the whole of life adrift on chance-driven change, the rock pools looked to those Victorians like gardens of prelapsarian bliss, glimmering enclosures in which nature seemed to have enshrined perfection and permanence.
We have inherited some of that Victorian longing for calm. We still go to the seaside for consolation and simplicity. Demands and anxieties seem to drop away there; things still are as they were when we were ten. The rock pools still beckon, the blennies and gobies still shimmer beneath us. But there are ironies in choosing the shore as a theatre for reassurance. Even if its changes are dependable and rhythmic, it is thick with variability. A tidal coast is filled with that paradoxical quality: reliable unreliability, both closed and open-ended, both familiar and strange. Regularity toys with uncertainty there. Nothing is more predictable than the coming and going of the tide and yet nothing about it can be relied on: daily revelation and daily erasure, daily loss and daily reacquisition.
This book is about those multiple layers between the tides, the ways in which the simple overlies the less-than-simple there, the extraordinary mirroring of human and animal life on its shores, in pools that are silent and beautiful and as full of threat as any rats’ alley or Roman circus. The intertidal is rich but troubled; as no coincidence, it is one of the most revelatory habitats on earth. Of all the great discoveries made in the science of nature, from a grasp of taxonomy, to the sequence of creatures through time revealed in the rocks, the adaptations of organisms to circumstance, the idea of natural selection – finally crystallising in Darwin’s mind as he spent eight long years examining the inner structures of the barnacle – the working of ecological webs and the governing importance of trophic cascades – all these ways of understanding the pattern of life first emerged from studying what was happening to animals and plants between the tides.
It is where you can look beyond your own reflection and find the marvellous an inch beneath your nose. ‘The soul wants to be wet,’ Heraclitus said in Ephesus 2,500 years ago. That is the impulse this book follows.
* * *
It began for me in springtime, thirty years ago. I had not long known Sarah, who was soon to be my wife, when she took me to a place she had known since she was a girl. Her family had been coming there for years, far out on the west coast of Scotland, in Argyll where David Balfour in Kidnapped had found the sea ‘running deep into the mountains and winding about their roots’, an intercut geography ‘as serrated as a comb’. Even on the map, land and sea there is as interlaced as the fingers of two hands.
We stayed the night about ten miles away in a small guest house on the shores of Loch Sunart. A polite atmosphere: cloths on the tables, charming, smiling service at dinner by the man who owned the hotel, a retired biologist, who dipped the end of his tie in the parsnip soup as he set it down in front of us. No one in the dining room said a word. The butter came on silver scallops, the oatcakes were in their own airtight tin and we whispered our secrecies over the venison and the crumble.
Next morning up early through the Atlantic oakwoods radiating their springtime green. Late May is the moment of perfection when the West Highlands start to acquire that burnish and glow which coats them for a few weeks at the beginning of summer. Cuckoos in the alders. Blackcaps in every other tree. Pied wagtails down on the wet rocks. The hollow notes of other, more distant cuckoos sounding as if they were calling through cupped hands. Everywhere the shadowed hyacinth blue of the bluebells and their scent.
Up out of the woods and on to the top of the hills. The whole riven province of Morvern, a mountainous fin of Scotland 80,000 acres wide and almost entirely surrounded by sea lochs, was laid out below us. We skirted the shoulders of the mountains and dropped to the pastures of a salmon river, past the freshwater loch at its head where the water slid out over the sandy beach, braided like silk, looking like whisky, and then along a heron-haunted shore to the sea.
Three miles to go. At last, we rounded a corner, past an eighteenth-century steading now used to shear and dag the sheep, and as the track turned, the bay appeared below, wide and tall, a world in itself, a half-circle of dark cliffs and wood-thickened slopes, the rim of those cliffs about 700 feet above the sea, waterfalls dropping over them at intervals and through the woods to the rocky shore. A track hairpinned steeply down under the old lime trees.
The bay, looking south-east towards Lismore and the hills above Oban.
It felt, as all good places feel, hidden from the world, enormous and strangely private. The bay looked out to the south, to the hills in Mull. To the south-east, seven miles away, the single white finger of the lighthouse on Lismore. Behind it, the hills above Oban.
This was the geometry: away from the wind, a cliff-backed semicircle of a bay, about a mile across and reaching half a mile in from the waters of the Sound, with strongly marked headlands at each side, the one to the west made of basalt, that to the east of limestone.
The head of the bay is lined with a dark beach, black basalt sand, the ground-down lavas from a volcano in Mull, lightened only with a scatter of broken cockles, an occasional bit of seaglass, the bottom of a bottle, some old limpets and mussels. Across it a small burn emerges from the flag irises of a bog and makes its way in zigzags that change with every tide and storm.
Even now, on each arrival, I go down to the beach. On the ebb, mounds of seaweed, most of it serrated wrack, lie about on the muddy-sandy surface. They look like piles of day-old salad. The sea extends away down the Sound in a perfect mirror. The abandoned shells lie on the drying sand. One half of a razor clam is out in the air, its gloss gone. There are some worm casts and a barnacle-encrusted rock, a bruised and battered lump of the ancient rocks brought here by the glaciers from further east.
I wade out into the shallows where, a foot deep and an hour before low water, the last of the tide is running between my calves. Little counter-whorls of current flicker in the surface just downstream of me. This is the world of flux and if I stand still in those shallows for a minute I am surrounded by the flitter and skitter of life. All kinds of resilient and defended creatures appear. Hermit crabs are suddenly busy on the sea floor in their winkles and whelks like porters with trolleys at a station. Everywhere I look, they are about their business. Some of those shells are encrusted with patches of the limy, self-hardening seaweed, the pink coralline. One has a sprig of wrack growing from its shell, an eighth of an inch tall. They scurry across the seabed, hurrying between the crumble-crusty, frilly-topped tubes of the sand-masons. There is a small greenish fish tooling around my feet, a common goby, less than half an inch long, its boxy body sprinkled with red spots, but with a bright green nose. I bring my hand down into the water beside and underneath it, a Gulliver presence in its Lilliputian world, and unlike any other fish I have ever known, it does not react but continues poking and looking, dark- and bubble-eyed, investigative at this intrusion, but not alarmed at the idea of an intrusion itself.
Low tide and the serrated wrack on the beach at the head of the bay.
A flicker-spotted fish glides past, sweeping its fins back and forth as it goes, spreading them in half-made, embryonic fan-wings, and then landing in the mud at my feet, the fish itself slowly reappearing from the dispersing cloud and puff of sand its arrival cast up. I photograph it – half in the shadow of my phone, half in light.
A little juvenile dab, three inches from nose to tail, slides along the sea floor beside me, a ripple in every pore, moulding its body to the contours of the sand as if wedded to them, as close as possible to that miniature landscape, a creature as liquid as the sea itself, a film of life, but which, as it pauses, turns invisible, mottled like its surroundings, its greyness speckled with white, banking on a principle opposite to the hermit crab beside it: one almost stupidly visible but dressed in borrowed armour; the other soft, subtle and discreet, the diplomat of this half-world, unseen to the heron that stands now a hundred yards away from me, waiting intently and anxiously, ever-ready to bid.
In the ebbing tide, little fleets of grey, white and black shrimps suddenly appear – they are Crangon crangon, called brown shrimps but they are far from brown – hundreds of them, making their steady soldierly progress over the sea floor, spotted and marbled with the same mixture of white and brown dots as the sand, following the water as it goes, bounce-swimming, antennae alert, settling for a moment on their toe-tips beside me, tails spread behind them in painted fans, all of them heading out to sea away from the warming shallows. Nothing is coming the other way; only with the next tide will the inhabitants of the beach return.
I push a little further out towards the headland on the edge of the bay. The kelp fronds here come up above the water as if they were the fins of dead fish. Their outer tips are broken and beaten by storms. Beneath their dark canopy is a graveyard of ex-lives, of smashed and abandoned shells, a recycling centre for the whole intertidal. Primitive colonies of tiny animals – sea mats – make hieroglyphs and diagrams in lobed and scratched patterns on the sheeny leather of the fronds. In the air the sea mats are glamorous but inert. Push them underwater and within a moment they flicker into magical, frondy, animal life.
In the shade of these weeds, the most unlikely drawing-room colours erupt on a damp Scottish coastline. The coralline makes a vermilion mat where the limpets dig their nests. Venetian-striped top shells crawl between the dried-blood red of the beadlet anemones. Bright yellow and green sponges line the polychrome pools.
All this aquarium life becomes visible if you pull the overhanging weeds away but put your head in under the enormous, jungly, slimed canopy of the kelp and you find yourself in a different country: threatening, shadowed, dark and even haunted where pink fleshy starfish wear ghost-blue lines down each of their arms; where the purple-black dahlia heads of their tentacled mouths are all that can be seen of giant anemones half-buried in the bowls of sand. And where in these shadows, the king and dominator of this world, the green crab, blotched and mottled, with a whole night sky of spots and patches on his carapace, emerges as the terror-giant of a miniature, barnacled world.

There is a line from a Gaelic love song, written in Mull just across the water: ‘Cha tàinig tràigh, gun muir-làn na dèidh’ (‘A low tide never came that wasn’t followed by a high tide’). Every ebb implies a flood, in a language where the word for ebb – tràigh – is the same as the word for beach. You will not find a beach without the promise of a rising tide. You may not love me now but love will come one day. An ebb tide is only a full tide in waiting. Trust your life to the turnings of the sea.
There is another side to it. The coming and going of the waters, their impermanence and unreliability, the sense in which the tide is a twice-daily catastrophe, has also played its part. In Applecross, on the west coast of the mainland of Scotland opposite Raasay, there is a bay called Ob’mhadaidh Ruaidh – the Bay of the Red Fox – from the story of a vixen that had been hunting on the shore who got her tongue deep into a large mussel, which closed on it, and held it while the tide rose and drowned her. Alexander Forbes, the early ethnographer who collected that story, also claimed that he had found a rat ‘drowned with its paw under a large limpet and its body twisted up in a crevice whence it had been unable to free itself’, while Alexander Stewart, Victorian columnist in the Inverness Courier, found a ‘dead kittiwake, but perfectly plump and fresh, lying on the top of a mass of drift tangle … One of its feet was firmly held in the vice-like grasp of a large mussel, the mussel in its turn being anchored by its byssus to a tangle root (Laminaria digitata) of immense size.’
The rising tide is unforgiving. This fluxing and flexing is a landscape, a halfscape, that reverberates with the mutability of things. It plays in our shared memory, part of ‘the challenge the ocean always poses’, as the American cultural critic Steve Mentz has said, ‘to know an ungraspable thing’.
Some of the most famous lines ever written, Ariel’s song near the beginning of The Tempest, embrace that shoreline ambiguity of perfection and destruction, the beautiful and the strange, the ‘menace and caress’ of the sea. These early moments in the play are themselves full of uncertainty: Ferdinand, the young prince of Naples, thinks his father the king is drowned, but we know he is not; these kings and princes are now homeless vagabonds on a storm-blasted shore; Ariel himself, the soul of poetry, is disguised not as a creature of the wind but as a little sea god and, as that watery spirit, sings the most untruthful and enigmatic of songs:
Full fadom fiue thy Father lies,
Of his bones are Corrall made:
Those are pearles that were his eies,
Nothing of him that doth fade,
But doth suffer a Sea-change
Into something rich, & strange:
Sea-Nimphs hourly ring his knell.
Burthen: Ding dong.
Harke now I heare them, ding-dong bell.
* * *
It is a hymn to the shore, afloat on ‘sea-sorrow’; the king’s body has become something like the floor of the sea. The colours of the shallow-deep waft over him. He is faded-rich. Encrusting jewels enshrine his head and his limbs transmute into submarine treasure. Everything that seems like threat and disaster is conjured here into masque-like glimmer. His corpse is a wonder of the wavering seas. And yet this is a song of death, an obsequy in which the elegance enshrines fatal loss, a drowning, a breaking of human connections, where the body is subject to the violence of the waves, and where sea nymphs ring the funeral bell. It is a place both of salt death and of scarcely imagined perfection. ‘What care these roarers for the name of King?’ the boatswain on their ship had cried as the winds had shrieked about them and now indeed the king has become treasure lying thirty feet down.

Sometimes, on a summer evening, when the tide is at full flood, and when, in the wonderful phrase Shakespeare used for this moment, it ‘makes a still-stand’, the whole of the bay outside the house goes quiet. Across the mile between its arms, a calm extends from headland to headland over what is, I reckon, about 300 acres of sea. If a fish moves anywhere in it, you can see that movement with your naked eye, the slightest stirring of its surface, a sleek molehill raised by the fish’s tail and lit by the last of the sun. I have seen a sea trout on an evening like this, the best part of a mile away, reaching up out of the water, and thrashing back down on to it, in pure silence. Seconds later the sound of its arc and fall came over towards me. And magically, once, a basking shark cruised to and fro across the bay, twenty minutes to the east, twenty minutes back, lazy and easy, leaving behind it in that wide still sheet of water the triple wake made by nose, fin and tail, each dragging its own pink-lit pencil line across the calm.
I realised soon enough that I loved that stillness and that a rock pool would have it. I searched the bay but could not find one: only beaches and a wide rim of ragged stone in which there are no true hollows to hold the water. Then, I thought, perhaps I could create something like a stillness-cupping pool, a parenthesis cut out of the world of flux, an extension in time of what in the open sea is only a moment of calm. A pool, or even two or three: to make them at the beginning quite naked, exactly as the words say – a rock pool, a dish of rock on the shoreline, as if it were part of the earth before life had come to clothe it. And then, slowly, to allow the sea to bring life to that dish, to make it a living thing. It would be gardening the sea, providing not flower beds but life beds.
Slack water high tide.
The foreshore in this bay is ‘Presumed Crown Land’. Long debate filled much of the nineteenth and twentieth centuries over the ownership of ‘that part of the land which is neither always wet, nor always dry due to the ebb and flow of the incoming and outgoing tide’. About half of the foreshore in Scotland was claimed by the neighbouring landowners, largely on the basis that their tenants, when gathering seaweed for fertiliser or to burn for its chemical residues, had paid the landowners rent for it. Scandalously, if rent was paid, ownership was implied. The relatively small amount of weed collected here meant that no rent was ever paid and so this bay went unclaimed. As Crown property, it is now administered by the Crown Estate Commissioners for Scotland.
Statutory public rights on the shore are thought to include (even if they are not yet enshrined in Scottish law):
swimming, sunbathing, playing games, going for a walk, having picnics, lighting fires and cooking food, gathering shellfish (except mussels and oysters, to which the Crown retains the rights), fishing (except salmon, ditto) and shooting wildfowl (as long as they are over the foreshore when shot), embarking, disembarking, loading and unloading a boat, drying nets, gathering bait and making sandcastles.
* * *
I wasn’t sure if my pools would come under the heading of ‘making sandcastles’ and so I applied to the Crown Estate Scotland for permission. They paused to think but in the end, for a small fee, and with the agreement of Marine Scotland, the government’s sea agency, I was allowed to make some pools on the edge of the bay at Rubha an t-Sasunnaich. A little woundingly, when I eventually sent some photographs of the work I had done, Tony Bennett, the Crown Estate Marine Officer for Argyll, said, ‘I see no issue with them as they do not appear to be any different to anything built by local children during the holidays.’ All the same, the pools at Rubha an t-Sasunnaich are now marked on the general asset map of the Crown Estate Scotland website, with the CES reference number AR1-34-2.
He was right though. Making the pools, even if they each took days of work, was partly a way of playing with nature; partly to make good a lack, to create a still-stand of my own, a small piece of a sea world by which I and Sarah and the children could wait and watch; and partly so that I could learn what this nature was. The pools would be discreet. I would be careful to keep them almost hidden, or at least scarcely noticeable. By definition, they would be invisible under the sea for much of the time. They would be an invitation to life, an act, as I learned to call it, of bio-receptivity, even bio-reciprocity, an enrichment of the habitat, not a subtraction from it.
The bay and its pools. The Scottish Crown owns the speckled land up to high-tide mark.
The shore, as Seamus Heaney once wrote, is where ‘things overflow the brim of the usual’, and that brim is at the heart of this book. It is an Old English word that has slowly migrated shorewards. Far back in its Germanic roots, the brim meant the turbulence of a breaking sea, a place where the world roars, and beyond that in the sea-less steppes of the Proto-Indo-Europeans in Central Asia, to brim was to hum like a bee, to make the noise of life. For the Anglo-Saxons it became the surf at the sea margin. From there it moved on again to be the lip or edge of anything, but one in which an overflow was always possible. A brim for us now is an edge at which the limit is gently but slowly reached, a place for the overtopping of a tide or flood, where, as Emily Dickinson once dreamed, our ‘Shoes / Would overflow with Pearl’.
There is something about a pool which – not to make too gross a pun on it – encourages the reflective, leads the mind not merely to transcribe the experience of the actual, to give it a topography, but allows the questions of why it means what it does, what its reality consists of, to what extent everything that confronts you is more than the local.
