The Walnut Harvest.

October's true insignia is worn on the hands. For two or three weeks, across the whole walnut belt of Europe, a certain brown-black stain appears on the fingers of otherwise unremarkable citizens, dark at the fingertips, seamed into the knuckle creases, immune to soap, pumice, and prayer; and the stained recognize each other in shops and offices with a small nod, because the stain cannot be faked and cannot be hidden, and everyone who has it knows what everyone else who has it did last weekend. They were at the walnuts. The juglone in the green husks writes it on the skin like a fortnight-long passport stamp, and civilization has never devised a more honest credential.

The harvest itself is the year's best theater of licensed regression. A walnut tree is not picked; it is shaken, thrashed with long poles, climbed by whichever cousin still climbs, and the nuts come down in a hard sweet rain that scatters the assembly underneath, everyone shrieking and hunched, the dog beside itself, the grandmother supervising from a safe distance with the air of a woman who has attended sixty of these and buried none of the casualties. Adults who have not thrown anything overhand in a decade hurl sticks into the canopy. Children are licensed to climb, hit things, and shout, all at once, an amnesty repeated nowhere else in the calendar. Then the gathering, on knees in the wet grass, hands going black husk by husk, buckets filling with that particular knock of nut on nut; and the accounting at the end, by the bucket, argued upward like all harvest statistics since Mesopotamia.

But the dispatch is less about the one loud afternoon than about what follows it, which is the quietest month in the household's year. The nuts cannot be eaten yet; fresh from the husk they are damp, their kernels bitter-skinned, their futures unformed. They must dry, and so they are spread, one layer deep, on newspapers, in the spare room, on the veranda floor, under beds in the serious households, whole rooms annexed and paved in walnuts; and there they lie for weeks, being turned occasionally by a passing hand, filling the house with a faint tannic sweetness, doing the one thing our century cannot abide: maturing at their own speed, in the dark, unmonitored. A room floored with drying walnuts is a factory in which the machinery is time itself. Production is invisible, inspection is a stroll, and the foreman's whole job is to leave the workforce alone.

The eating, when it finally begins, installs its own institution: the winter cracking session, the bowl and the hammer, or the nutcracker in the fancy houses, or the older art, two nuts squeezed against each other in one strong hand until the weaker surrenders. Cracking walnuts cannot be hurried and cannot quite occupy the whole mind, which is the design specification, whether anyone wrote it down or not, of every great fireside occupation: hands employed, attention half-claimed, the remainder free to drift into the talk. Whole winters of family conversation have run on walnut power, the shells accumulating like the minutes of the meeting, the perfect halves set aside for the cakes with the reverence owed to anything that comes out whole.

And presiding over the entire economy, the tree. A walnut is the slowest promise in the garden: planted for grandchildren by people who knew the arithmetic and made it anyway, bearing seriously only after a decade or two, then bearing for a century. Every full-grown walnut at a gate is therefore somebody's completed act of faith, shade and harvest delivered to descendants the planter priced in but never met. The one in my grandmother's yard, the one that supervised the long afternoons this gazette has written about before, was planted, family arithmetic insists, by her own grandfather; it has outlived him, her, the political systems of its youth, and every deadline any of them ever worried over, and it is still paying October dividends to people whose names the planter could not have guessed.

The stains on my hands this week will fade by the middle of November; the nuts on the floor of the small room will be ready when they are ready and not before; the tree by the gate has already begun, in its unhurried accounting, next year's crop. Somewhere in all this there is a lesson about time so obvious that the gazette declines to spell it out, on the grounds that it comes off on the fingers of anyone who handles the material directly, and does not wash off, either.
