警枕

Twenty-sixth of August, 2037, a Wednesday, Fresno. The trays had been on the ground seven days: 104, 106, 103 degrees, the sky blue without a thread of cloud. On the trays the fruit changed day by day: green going brown for two days, more brown than green by the fourth, wrinkled and going purple-black by the seventh. Every morning Rose sat at the head of the row, not looking at the field but at the sky to the south-west. Every evening Nora read her the forecast. The 22nd: a mass of cloud off Mexico moving north, fifteen per cent. The 24th: it had grown, and had a name, a tropical storm; its tail might brush southern California; the valley, fifteen. The 26th: it had edged north; the valley, twenty per cent, the night of the thirty-first into the morning of the first. Nobody spoke. Martin polished his shears for a long time.

"Bring the books." Not this year's: the years it rained. Thirteen of seventy-one Septembers, stacked on the table; she turned each to its last page. "In nine of the thirteen, the rain came between the tenth and eighteenth day after the trays went down. Those are the days the fruit is half dry and fears rain most. Wet fruit can take a rain and dry again; dry fruit dries off in the wind; half-dry fruit splits, the sugar comes out, the insects come, the mould grows. The thirty-first is day eleven." Twenty per cent. "At ten per cent I have them bring the trays in. At twenty, we roll." Nora: day eleven is early; the inner fruit isn't dry, rolled up it will sweat and spoil. "I know. Sweating spoils a tenth. Rain spoils half." Look at the forecast once more on the thirtieth; if it's still twenty or more, roll on the thirty-first at first light.

The thirtieth: thirty per cent. At five on the thirty-first, before light: "Roll." Martin, Nora, me, the young neighbours, and Carol, who had never seen trays rolled, let alone rolled against rain. Lift one end of the tray with the fruit on it and roll it toward the other end into a tube like a fat paper cigarette, fold both ends, leave it on the slope; rain on the paper runs down to the foot of the slope. Too loose and it won't shed rain; too tight and it can't breathe. From her chair: "Looser." Then: "That'll do." Four thousand trays from dawn to dark; at noon 102 degrees and nobody stopped. By sunset the old half was rows of paper rolls lying on the slopes like felled timber; in the south-west the white cloud had thickened and climbed, grey underneath.

That night I sat by Rose's window facing south-west; she sat beside me with the 2037 book on her knees. Martin lay in the next room fully dressed, boots on; Nora paced upstairs. Midnight: wind, the tree first, then the window frame; a wet wind. "It's turned." At one I went out to the porch. On the step sat an old man in a wide old robe and a soft black cap, a long white beard, beside him a round log a foot long and thick as a bowl, worn shiny at both ends, writing on a sheaf of papers under the porch light, pausing after each line to look at the south-western sky. Without turning: "Is she asleep?" No. "Good. Tonight someone has to stay awake." Sima Guang. — M.

Memo to file. Fresno, 26 August – 1 September 2037. A premium paid.

1. Rose's base rates. Of thirteen rain Septembers in seventy-one years, nine rains fell between day ten and day eighteen after the trays went down, when the fruit is half dry: it splits, sugar comes out, insects and mould follow. 31 August was day eleven.

2. Her rule. Ten per cent: bring the trays in. Twenty: roll. Nora's objection: rolled on day eleven, the inner fruit will sweat. "Sweating spoils a tenth. Rain spoils half." One more day of forecasts; still thirty; roll at first light.

3. The rolling. Four thousand trays, dawn to dark, 102 degrees at noon. Each tray rolled into a paper tube, ends folded, left on the slope; rain on paper runs down the slope. Too loose sheds nothing; too tight can't breathe. Carol came to watch and stayed to help.

4. The waking pillow. Sima Guang wrote his history for nineteen years, mostly at night. "Asleep lightly, the head stays still and the log stays still. Asleep deeply, the head tips, the log rolls, and I wake and write on." The probes in Shanxian, Ahmat's son on the three o'clock round, Rose's window: "Those probes are their waking pillow. It doesn't forbid sleep. People must sleep. It lets them wake when the sky turns."

5. The jar. At seven, a child fell into a full water jar; the other children ran for the grown-ups; he smashed the jar with a stone and the child lived. A valuable jar, months of a family's money. "Those who ran for help weren't wrong. But by the time the grown-ups came, the child would have gone under. Some things can't wait, and when they can't, you must be willing to break something." Rolling on day eleven, and the tenth it costs, is the jar.

6. The line. "Someone who sleeps too deeply doesn't know when the sky changes. A pillow of round wood doesn't forbid sleep; it lets you wake from it." Chang Yushan's three nights in ten had no waking pillow. He also wrote the night down: which year, which day, who was where and why they were awake; in a thousand years someone reading that line will know an old woman didn't sleep. "When my book was finished I was sixty-six, my eyes dim, half my teeth gone; I told the emperor all my strength was in this book." At her lit window: "Her seventy-one books are the same."

7. The rain. Two a.m., the wind louder, branches beating the barn roof. Half past two, Martin at the door, looked, lay down again in his boots. Three o'clock: a single tick on the eaves. Another. Drops on the glass. She wrote a time: 3:02. Twenty-odd drops on the tin roof, a pause, a few more; at 3:12, nothing, the wind still rising but nothing falling. "It's gone over. The tail swept past." The field? "The ground isn't even wet." She closed her eyes; I thought she slept; "Go to bed. I'll sit a while."

8. Morning. On the rolls, a few dried drop marks the size of a fingernail, three to five per roll; the slope dry. The neighbours hadn't rolled; their fruit dry too, a few damp spots gone at sunrise. "Wasted your effort, eh?" I said nothing. In the book: "1 September | roll | 30% | rain, 3:02 to 3:12, ground not wet. Rolled for nothing." One of her forty-odd times in sixty-odd.

9. The cost. Martin: rolled early, a fair share has sweated soft and needs more sun, some will drop a grade; about a tenth less at sale. Rose: "A tenth. Nine-tenths kept." Nora: Grandma, it didn't rain. "Not raining is what the sky gave. Rolling is what we gave. Next year, the same." On Wall Street I would have called the tenth the premium and the day's work the cost of carry. She called it rolling for nothing, and wrote it down in the same hand as the times it rained.

10. Where the rule came from. After the drops stopped: "1981 had a wind like this. The forecast said ten per cent, and in those days I didn't bring them in at ten. It rained three days. Harry crouched at the end of the row and cried. From the next year, at ten per cent, I had them brought in." On the porch earlier in the week: Harry came from the next town and married her in 1965; he never believed her about the sky, but he believed her about the trays. Since he died she has watched the sky alone for twenty-eight years. "Your mother sewed thirteen years; I've kept seventy-one. Both night work."

11. Voices on the premium. Carol, next morning: "If I were still at the plant I'd dock you for that sweated tenth." Rose: "Dock it. That tenth I bought." Nora, reading my note: what do you call this on Wall Street? A premium. "Grandma calls it rolling for nothing." Her name is better than mine. The neighbour's son stood behind his father a long time looking at our rolls and said nothing. Sima Guang, leaving: "Tomorrow morning you may think you stayed up for nothing. Don't." Asked if he ever broke anything else: "A great roll of my own writing, several years' work. It was wrong; I took it all apart and wrote it again." And he kept a separate book explaining why he believed one source over another, so anyone who doubted him could check.

12. The handover, in detail. "Every day one line, four parts: the date; what you say; what the forecast says; the sky. What you say, write the night before; the sky, the next night." Nora: what I say? I can't say anything. "Then write: can't say. Write for a year and you'll be able to say a little." Rose to me: next September are you coming? Yes. "Then next year, you and Nora, two of you awake." That night her light went out at nine.

13. The pickup. Unrolled on 4 September, three more days of sun; the sweated fruit hardened a little but darkened. 8 September, into the bins, to the co-operative, where a man of about thirty now sits at Carol's table with a moisture meter, a scale and the tweezers she left. "Two point four." Martin: rolled early, the sweated tenth. That line in the book is Nora's: 8 September, picked up, 2.4; and after it three characters: rolled for nothing.

14. Next. "Next year's book, you keep." Nora froze. "Start today. Copy the first of September after mine. Seventy-one years; my writing won't go straight any more."

"Someone who sleeps too deeply doesn't know when the sky changes. A pillow of round wood doesn't forbid sleep; it lets you wake from it."
Sima Guang, the Song historian who spent nineteen years compiling the Comprehensive Mirror for Aid in Government, was said to sleep on a round log so that when he fell into deep sleep it would roll and wake him, and he would get up and write. As a child of seven he was remembered for a different kind of alertness: when a playmate fell into a large water jar and the other children ran for help, he broke the jar with a stone and saved the boy.
A raisin grower facing a thirty per cent chance of rain on half-dried fruit makes a decision of the same shape. Rolling the paper trays early protects the crop from rain but costs about a tenth of its value, because some fruit sweats inside the rolls. In this chapter the storm's tail brought ten minutes of scattered drops and nothing more. The early rolling was, in hindsight, unnecessary.
Risk managers know the feeling: most hedges expire unused, and the premium looks wasted. The discipline lies in recording those days as honestly as the days the protection paid off, and in making the same decision next time.
"Not raining is what the sky gave. Rolling is what we gave."
