"The very same engineers who dealt with the Leaning Tower of Pisa ... which was where?" "Italy!" "Right. They were brought over to assess the situation.

"'It wants to go,' they said.

"'Well, what can you say about that?' the mayor of New York asked.

"To which they replied: 'There's nothing to say about that.'

"Of course they tried to save it. Although 'save' might not be the right word, as it did seem to want to go. Maybe 'detain' is the right word. Chains were moored to the banks of the islands, but the links soon snapped. Concrete pilings were poured around the perimeter of the Sixth Borough, but they, too, failed. Harnesses failed, magnets failed, even prayer failed.

"Young friends, whose string-and-tin-can phone extended from island to island, had to pay out more and more string, as if letting kites go higher and higher.

"'It's getting almost impossible to hear you,' said the young girl from her bedroom in Manhattan as she squinted through a pair of her father's binoculars, trying to find her friend's window.

"'I'll holler if I have to,' said her friend from his bedroom in the Sixth Borough, aiming last birthday's telescope at her apartment.

"The string between them grew incredibly long, so long it had to be extended with many other strings tied together: his yo-yo string, the pull from her talking doll, the twine that had fastened his father's diary, the waxy string that had kept her grandmother's pearls around her neck and off the floor, the thread that had separated his great-uncle's childhood quilt from a pile of rags. Contained within everything they shared with one another were the yo-yo, the doll, the diary, the necklace, and the quilt. They had more and more to tell each other, and less and less string.

"The boy asked the girl to say 'I love you' into her can, giving her no further explanation.

"And she didn't ask for any, or say 'That's silly,' or 'We're too young for love,' or even suggest that she was saying 'I love you' because he asked her to. Instead she said, 'I love you.' The words traveled the yo-yo, the doll, the diary, the necklace, the quilt, the clothesline, the birthday present, the harp, the tea bag, the tennis racket, the hem of the skirt he one day should have pulled from her body." "Grody!" "The boy covered his can with a lid, removed it from the string, and put her love for him on a shelf in his closet. Of course, he never could open the can, because then he would lose its contents. It was enough just to know it was there.

"Some, like that boy's family, wouldn't leave the Sixth Borough. Some said, 'Why should we? It's the rest of the world that's moving. Our borough is fixed. Let them leave Manhattan.' How can you prove someone like that wrong? And who would want to?" "I wouldn't." "Neither would I. For most Sixth Boroughers, though, there was no question of refusing to accept the obvious, just as there was no underlying stubbornness, or principle, or bravery. They just didn't want to go. They liked their lives and didn't want to change. So they floated away, one millimeter at a time.

"All of which brings us to Central Park. Central Park didn't used to be where it is now." "You just mean in the story, right?"

"It used to rest squarely in the center of the Sixth Borough. It was the joy of the borough, its heart. But once it was clear that the Sixth Borough was receding for good, that it couldn't be saved or detained, it was decided, by New York City referendum, to salvage the park." "Referendum?" "Vote." "And?" "And it was unanimous. Even the most stubborn Sixth Boroughers acknowledged what must be done.

"Enormous hooks were driven through the easternmost grounds, and the park was pulled by the people of New York, like a rug across a floor, from the Sixth Borough into Manhattan.

"Children were allowed to lie down on the park as it was being moved. This was considered a concession, although no one knew why a concession was necessary, or why it was to children that this concession must be made. The biggest fireworks show in history lit the skies of New York City that night, and the Philharmonic played its heart out.

"The children of New York lay on their backs, body to body, filling every inch of the park, as if it had been designed for them and that moment. The fireworks sprinkled down, dissolving in the air just before they reached the ground, and the children were pulled, one millimeter and one second at a time, into Manhattan and adulthood. By the time the park found its current resting place, every single one of the children had fallen asleep, and the park was a mosaic of their dreams. Some hollered out, some smiled unconsciously, some were perfectly still."

"Dad?" "Yes?" "I know there wasn't really a sixth borough. I mean, objectively." "Are you an optimist or a pessimist?" "I can't remember. Which?" "Do you know what those words mean?" "Not really." "An optimist is positive and hopeful. A pessimist is negative and cynical." "I'm an optimist." "Well, that's good, because there's no irrefutable evidence. There's nothing that could convince someone who doesn't want to be convinced. But there is an abundance of clues that would give the wanting believer something to hold on to." "Like what?" "Like the peculiar fossil record of Central Park. Like the incongruous pH of the reservoir. Like the placement of certain tanks at the zoo, which correspond to the holes left by the gigantic hooks that pulled the park from borough to borough." "Jose."

"There is a tree—just twenty-four paces due east of the entrance to the merry-go-round—into whose trunk are carved two names. There is no record of them in the phone books or censuses. They are absent from all hospital and tax and voting documentation. There is no evidence whatsoever of their existence, other than the proclamation on the tree. Here's a fact you might find fascinating: no less than five percent of the names carved into the trees of Central Park are of unknown origin." "That is fascinating."

"As all of the Sixth Borough's documents floated away with the Sixth Borough, we will never be able to prove that those names belonged to residents of the Sixth Borough, and were carved when Central Park still resided there, instead of in Manhattan. Some people believe they are made-up names and, to take the doubt a step further, that the gestures of love were made-up gestures. Others believe other things." "What do you believe?"

"Well, it's hard for anyone, even the most pessimistic of pessimists, to spend more than a few minutes in Central Park without feeling that he or she is experiencing some tense in addition to the present, right?" "I guess." "Maybe we're just missing things we've lost, or hoping for what we want to come. Or maybe it's the residue of the dreams from that night the park was moved. Maybe we miss what those children had lost, and hope for what they hoped for."

"And what about the Sixth Borough?" "What do you mean?" "What happened to it?" "Well, there's a gigantic hole in the middle of it where Central Park used to be. As the island moves across the planet, it acts like a frame, displaying what lies beneath it." "Where is it now?" "Antarctica." "Really?"

"The sidewalks are covered in ice, the stained glass of the public library is straining under the weight of the snow. There are frozen fountains in frozen neighborhood parks, where frozen children are frozen at the peaks of their swings—the frozen ropes holding them in flight. Livery horses—" "What's that?" "The horses that pull the carriages in the park." "They're inhumane." "They're frozen mid-trot. Flea-market vendors are frozen mid-haggle. Middle-aged women are frozen in the middle of their lives. The gavels of frozen judges are frozen between guilt and innocence. On the ground are the crystals of the frozen first breaths of babies, and those of the last gasps of the dying. On a frozen shelf, in a closet frozen shut, is a can with a voice in it."
