Chapter 30: The Frost

The frost came back in April, a late frost, hard, the temperature dropping to minus six on a clear night when the sky was black and the stars were sharp and the dale lay open to the cold the way a wound lay open to the air, and Tom woke at five and knew it before he looked, knew it from the silence, the particular silence that frost produced, the silence that was not the absence of sound but the suppression of it, the cold pressing the noise out of the dale the way a hand pressed the air out of a bellows, everything muted, everything held, the river quieter, the sheep quieter, the birds waiting for the warmth that would not come until mid-morning, the whole dale paused, suspended, the frost holding everything in place the way the hearting held the stones.

He went to the window and the glass was covered on the inside with a film of condensation that had frozen into patterns, ferns of ice, the water on the glass having crystallised in shapes that looked like plants, like fronds, like the fossils of the ancient ferns that you sometimes found in the shale beds between the limestone, and Tom looked at the ice on the glass and thought about the water that was inside the wall on the hillside above High Scar Farm, the water that had seeped into the joints between the stones and into the spaces between the hearting and that was now freezing, expanding, exerting a pressure on the stones that the stones could not resist.

This was how walls failed. Not suddenly, not catastrophically, not the way buildings failed in earthquakes or storms, the sudden collapse, the dramatic failure, but slowly, incrementally, the frost working on the wall over years and decades, each freeze-thaw cycle pushing the stones a fraction of a millimetre further apart, the gaps widening, the hearting loosening, the face stones moving outward, the wall's structure degrading so slowly that no one noticed until the lean was visible, until the face was bulging, until the morning came when the wall was on the ground and the farmer looked at the gap and said it went in the night, as though the failure had been sudden, as though the wall had been sound on Tuesday and down on Wednesday, when in fact the wall had been failing for years, for decades, the frost doing its patient work, the ice doing what ice did, which was to occupy more space than the water it had been, to expand, to push, to pry.

Tom understood frost. He understood it the way a doctor understood disease, not as an enemy but as a force, a process, a thing that followed laws and that could be anticipated and that could be defended against but that could not be stopped, because frost was not a choice, was not a decision, was a consequence of the temperature falling below a certain point and the water changing its state and the changed water behaving differently from the unchanged water, the solid occupying more space than the liquid, the expansion inevitable, the physics absolute, and the wall had to accommodate this physics or fail.

The accommodation was the hearting. Tight hearting, well-packed hearting, hearting that filled every void and left no space for water to collect, this was the wall's defence against the frost, because water could not freeze in a space that was already occupied by stone, could not expand into a void that was already filled, and the tighter the hearting the less water the wall could hold and the less damage the frost could do. This was why Jim had been so insistent about the hearting, why the first lesson and the last lesson and every lesson in between had been about the hearting, because the hearting was the wall's immune system, the invisible defence against the invisible enemy, the thing that stood between the wall and the force that would destroy it.

Tom did not go to the wall. The frost made the ground too hard to work, the stones too cold to handle, the hands too stiff to grip, and the morning was a morning for staying home, for drinking tea in the kitchen, for sitting at the table and looking at the dale through the window, the dale white and still and frozen, the fields glazed with frost, the walls dark against the white, the coping stones furred with ice crystals that caught the early sun and glittered like the scales of a fish.

Helen had left for her rounds. She left every morning regardless of the weather, the frost no impediment to the sick, the cold no barrier to the dying, and her car had crept down the icy road with its headlights on and its wipers clearing the frost from the windscreen, and Tom had watched her go and had felt the thing he always felt when she left, which was not anxiety exactly but a consciousness of her absence, an awareness of the space she left behind, the gap in the house, the Helen-shaped void that the morning filled with silence and tea and the sounds of a man alone.

He thought about frost and about walls and about the relationship between the force that destroyed and the force that built. Frost destroyed walls. But frost also built landscapes. The dale itself was partly the product of frost, the freeze-thaw cycles of the ice ages having shattered the rock and loosened the soil and carved the cliffs and shaped the valleys, the frost working on the landscape over millennia the way it worked on the wall over decades, breaking things down, breaking things apart, and the breaking was not purely destructive, was also creative, because the broken rock became the scree and the scree became the soil and the soil became the fields and the fields were bounded by the walls that were built from the stone that the frost had broken, the cycle running from destruction to creation and back again, the frost both the enemy and the origin, the force that took the wall down and the force that had made the stone the wall was built from.

He thought about this and the thinking was the kind of thinking that the frost allowed, the slow thinking, the deep thinking, the thinking that happened when the hands were idle and the mind had no work to do but the work of contemplation, the mental walling, the building of ideas, and he thought that the dale was full of such cycles, full of forces that were both destructive and creative, the river that eroded the banks and deposited the silt, the wind that stripped the soil and scattered the seeds, the rain that dissolved the limestone and created the caves and the potholes and the sinkholes and the underground rivers that ran beneath the dale in channels carved by the same water that fell on the walls and seeped into the joints and froze and expanded and pushed the stones apart.

And he thought about Arthur, about the disease that was both destroying Arthur and revealing him, the cancer stripping away the flesh, the weight, the strength, the ability to walk and eat and stand, and in the stripping revealing the man beneath, the essential Arthur, the core, the hearting, the part of the man that remained when everything else was taken away, the part that sat in the chair by the range with the through-stone on the armrest and watched the wall from the window and spoke the names of the fields to Helen and turned the stone in his thin hands, the part that was irreducible, that could not be further diminished, the foundation course of the man's being.

The frost was the disease. The disease was the frost. Both were forces that acted on structures, that exploited weaknesses, that found the gaps and the voids and the spaces where the defences were thin, and both were patient, relentless, indifferent, the frost not caring whether the wall stood or fell, the disease not caring whether the man lived or died, the force simply doing what the force did, following the laws that governed it, the physics of expansion, the biology of replication, the process running to its conclusion regardless of the value of the thing it was destroying.

But the hearting resisted. The well-packed hearting resisted the frost, held the wall together, maintained the structure against the force that would undo it, and Arthur's hearting, the invisible core of the man, the part that was the farm and the dale and the walls and the names of the fields and the marks of the sheep, this hearting resisted too, held the man together, maintained the structure of his identity against the force that was stripping his body, and the resistance was not dramatic, was not heroic, was simply the persistence of the well-built thing, the thing that stood because it was soundly made, the thing that endured because its interior was solid.

At ten the frost began to ease. The sun climbed above the eastern ridge and the light fell across the dale and the ice on the windows began to melt, the fern patterns dissolving, the frozen water returning to liquid, the liquid running down the glass in small streams that caught the light and broke it into colours, and the dale began to move again, the sounds returning, the sheep calling, the river finding its voice, the birds starting their morning, the pause ending, the frost releasing its grip.

Tom put on his boots and his jacket and went outside and stood in the yard and breathed the cold air, the air that was warming but was still cold, still carrying the memory of the frost, the way a stone carried the memory of the wall it had been in, the experience embedded in the material, invisible but present, and he looked up the dale toward High Scar Farm, toward the hillside where the wall stood, and he thought about the frost that had worked on the wall in the night, the ice that had formed in the joints and expanded and pushed, and he thought about the hearting that he had packed, the tight hearting, the careful work, the voids filled, the gaps closed, and he trusted the hearting, trusted the work of his hands, trusted the wall to resist the frost, to stand against the expansion, to hold.

He would not know until he got there. He would not know until he climbed the hill and put his hand on the coping and walked the length of the wall and looked for the signs, the telltale lean, the stone pushed proud, the crack in the face that said the frost had found a way in, and he would not get there today, the ground still too hard, the morning too cold, and so he stood in the yard and looked up the dale and trusted and waited, and the waiting was the hardest part of the craft, the not-doing that was harder than the doing, the faith in the work that you could not see, the faith in the hearting, the invisible substance, the thing that held.

He went back inside and made tea and sat at the table and the morning passed and the frost retreated and the dale thawed and the water ran from the melting ice and the ground softened and the air warmed and the day became a day when work was possible but Tom did not work, sat instead in the kitchen and thought about frost and walls and the forces that acted on the things men built, the forces that were patient and relentless and that could not be stopped but could be resisted, could be held off, could be survived if the building was sound, if the hearting was tight, if the invisible interior was as carefully constructed as the visible exterior, and he sat and drank tea and the dale moved around him and the wall stood on the hillside and the frost had done its work and the hearting had done its work and the two forces, the destroying and the holding, had met in the joints of the wall in the darkness of the night and had contended and the hearting had held, the hearting had held, and the wall stood.
