have you eaten yet

The mountain was made of bird shit and it was more than a hundred and fifty feet high.

Seabirds had been roosting on the Chincha Islands, three dry rocks off the coast of Peru, for something like the length of recorded history — cormorants and boobies and pelicans, millions of them, generation over generation, and every one of them leaving behind what birds leave behind. Anywhere else the rain would have taken it. But the Humboldt Current runs cold up that coast and wrings the weather dry before it reaches land, so on the Chinchas it never rained, and the droppings never washed away. They dried. They stacked. The nitrogen that would have leached out in a single wet season anywhere on Earth stayed locked in the pile, century after century, until the pile was a hill and the hill was a cliff you could see from a ship.

Alexander von Humboldt carried a sample back to Europe around 1804, and the chemists there found it was the most concentrated fertilizer anyone had ever measured. This mattered more than it sounds. The fields of Europe and the American East were tired — two hundred years of the same crops had pulled the life out of the soil, and the yields were falling, and nobody had a fix. And here was an island that was nothing but fertility, dried and stacked and waiting, a bank of every good harvest the Pacific had deposited for a thousand years. The world did the obvious thing. It went to dig up the bank.

Between 1840 and 1870 Peru shipped roughly twelve million tons of it. The government took about sixty percent off the top and lived on the rest — paid its debts with dung, floated its budget on dung, became for thirty years a country whose treasury was an island of dried droppings that other countries could not stop buying. The guano paid for railroads and palaces and the abolition of the country’s remaining slavery. It was the strangest fortune in the world and for a while it looked bottomless.

It was not bottomless, and someone had to dig it.

After Peru freed its slaves the plantations and the islands still wanted bodies, so the ships went to Guangdong. Between 1849 and 1874 something like a hundred thousand men were carried from southern China to Peru under contracts most of them could not read, having been told by the agents who signed them that they were bound for the gold fields of California. They were not bound for California. Thirty thousand or so ended up on the guano islands. The work was to break the packed dung with picks and shovel it down chutes to the boats, and the dung as it broke gave off ammonia, and the ammonia burned the lungs and the eyes, and there was no shade on a bare rock at that latitude and no way off it. Men who tried to swim to the mainland went into the Humboldt Current, the same cold current that had kept the island dry, and the current took them. The ones who stayed killed themselves at among the highest rates anyone recorded, because the fastest way off a bare rock in the ocean was to jump. This is not a story with the cruelty in the margins. The cruelty was the whole labor supply. The fertility of the tired fields of the north was purchased, directly, with the lungs of men who had been lied to about where the ship was going.

Then the mountain ran out. You can only dig up a thousand years of deposit once. Exports fell from five hundred and seventy-five thousand tons in 1869 to under three hundred and fifty thousand by 1873; the islands went down to the bare rock they had always been under the pile. A global depression hit the same year and the demand went with it, and Chile started selling saltpeter that did the same job cheaper, and Peru — which had forgotten how to be a country that was not rich — found itself thirty-five million pounds in debt, the largest in the hemisphere. And then the countries went to war over what nitrate was left, and Peru lost, and the guano era ended the way it had run: as a fight over the right to dig something out of the ground until it was gone.

Everything the mountain built came apart. The money, the palaces, the credit, the war — footnotes now, the kind of thing you have to be told. The islands are still there, low and stripped, with a fraction of the birds and a fraction of the pile, worked at a trickle. Nobody outside a specialist remembers that the modern world spent thirty years running on the concentrated droppings of Pacific seabirds. The substance the whole thing was about is the part that vanished most completely.

What lasted was the men.

Of the hundred thousand, maybe fifty thousand survived their contracts, and the ones who survived drifted off the haciendas and the islands toward Lima, toward a street called Calle Capón in what became the Barrio Chino. They were single men, most of them, Cantonese, a long way from anyone, and they did what the far-from-home do: they cooked the food of the place they’d left using the ingredients of the place they were. They put the high-heat Cantonese wok against Peruvian beef and Peruvian onion and the yellow ají chili, and got something charred and glazed and sauced that was neither one country’s food nor the other’s. They opened little rooms where you could eat it. The rooms multiplied. The food got a name, and the name was the Cantonese for have you eaten yet — chī fàn, the thing you say to someone you care about when they come through the door, softened in a new mouth to chifa.

There are more than six thousand chifas in Lima now. Lomo saltado — the beef, the onion, the ají, the char, thrown together over a fire hot enough to make a whole country’s mouth water — is about as close to a national dish as Peru has. The greeting is on signs in every neighborhood. A country eats, most nights, the improvisation of men who were shipped there in a lie to dig up an island of shit until it killed them.

I don’t want to call that redemption, because it isn’t. The food does not pay for the lungs. Nothing pays for the lungs; the men who burned are just burned, and a good dinner does not reach back thirty years to un-lie the contract or un-drown the swimmer. The guano got dug up and sold and spent and warred over and forgotten, exactly as intended, and the men who dug it were meant to be spent the same way and forgotten the same way, and mostly the record obliged.

But the thing that was supposed to consume them didn’t get the last word, and the thing that lasted wasn’t the fortune. It was the smallest thing they carried. Not the money, which was never theirs. Not the guano, which is gone. A question you ask at a doorway. Have you eaten yet. It turned out to be the most durable cargo that ever came off those islands, and it’s the only one anyone still says out loud.
