Clarke pursed his lips and waited for something a little more specific.

“Galileo and Descartes were only harbingers. Something is happening now-the mercury is rising in the ground, like water climbing up the bore of a well.”

Enoch couldn’t get Oxford out of his mind-Hooke and Wren and Boyle, all exchanging thoughts so quickly that flames practically leaped between them. He decided to try another tack. “There’s a boy in Leipzig like this one. Father died recently, leaving him nothing except a vast library. The boy began reading those books. Only six years old.”

“It’s not unheard-of for six-year-olds to read.”

“German, Latin, and Greek?”

“With proper instruction-”

“That’s just it. The boy’s teachers prevailed on the mother to lock the child out of the library. I got wind of it. Talked to the mother, and secured a promise from her that little Gottfried would be allowed free run of the books. He taught himself Latin and Greek in the space of a year.”

Clarke shrugged. “Very well. Perhaps little Gottfried is the one.”

Enoch then should’ve known it was hopeless, but he tried again: “We are empiricists-we scorn the Scholastic way of memorizing old books and rejecting what is new-and that is good. But in pinning our hopes on the Philosophick Mercury we have decided in advance what it is that we seek to discover, and that is never right.”

This merely made Clarke nervous. Enoch tried yet another tack: “I have in my saddlebags a copy of Principia Philosophica, the last thing Descartes wrote before he died. Dedicated to young Elizabeth, the Winter Queen’s daughter…”

Clarke was straining to look receptive, like a dutiful university student still intoxicated from last night’s recreations at the tavern. Enoch remembered the stone on the string, and decided to aim for something more concrete. “Huygens has made a clock that is regulated by a pendulum.”

“Huygens?”

“A young Dutch savant. Not an alchemist.”

“Oh!”

“He has worked out a way to make a pendulum that will always go back and forth in the same amount of time. By connecting it to the internal workings of a clock, he has wrought a perfectly regular time-piece. Its ticks divide infinity, as calipers step out leagues on a map. With these two-clock and calipers-we can measure both extent and duration. And this, combined with the new method of analysis of Descartes, gives us a way to describe Creation and perhaps to predict the future.”

“Ah, I see!” Clarke said. “So this Huygens-he is some kind of astrologer?”

“No, no, no! He is neither astrologer nor alchemist. He is something new. More like him will follow. Wilkins, down in Oxford, is trying to bring them together. Their achievements may exceed those of alchemists.” If they did not, Enoch thought, he’d be chagrined. “I am suggesting to you that this little boy may turn out to be another one like Huygens.”

“You want me to steer him away from the Art?” Clarke exclaimed.

“Not if he shows interest. But beyond that do not steer him at all-let him pursue his own conclusions.” Enoch looked at the faces and diagrams on the wall, noting some rather good perspective work. “And see to it that mathematics is brought to his attention.”

“I do not think that he has the temperament to be a mere computer,” Clarke warned. “Sitting at his pages day after day, drudging out tables of logarithms, cube roots, cosines-”

“Thanks to Descartes, there are other uses for mathematics now,” Enoch said. “Tell your brother to show the boy Euclid and let him find his own way.”

THE CONVERSATION MIGHT NOT HAVEgone precisely this way. Enoch had the same way with his memories as a ship’s master with his rigging-a compulsion to tighten what was slack, mend what was frayed, caulk what leaked, and stow, or throw overboard, what was to no purpose. So the conversation with Clarke might have wandered into quite a few more blind alleys than he remembered. A great deal of time was probably spent on politeness. Certainly it took up most of that short autumn day. Because Enoch didn’t ride out of Grantham until late. He passed by the school one more time on his way down towards Cambridge. All the boys had gone home by that hour save one, who’d been made to stay behind and, as punishment, scrub and scrape his own name off the various windowsills and chair-backs where he’d inscribed it. These infractions had probably been noticed by Clarke’s brother, who had saved them up for the day when the child would need particular discipline.

The sun, already low at mid-afternoon, was streaming into the open windows. Enoch drew up along the northwest side of the school so that anyone who looked back at him would see only a long hooded shadow, and watched the boy work for a while. The sun was crimson in the boy’s face, which was ruddy to begin with from his exertions with the scrub-brush. Far from being reluctant, he seemed enthusiastic about the job of erasing all traces of himself from the school-as if the tumbledown place was unworthy to bear his mark. One windowsill after another came under him and was wiped clean of the name I. NEWTON.

How are these Colonies of the English increas’d and improv’d, even to such a Degree, that some have suggested, tho’ not for Want of Ignorance, a Danger of their revolting from the English Government, and setting up an Independency of Power for themselves. It is true, the Notion is absurd, and without Foundation, but serves to confirm what I have said above of the real Encrease of those Colonies, and of the flourishing Condition of the Commerce carried on there.

-DANIELDEFOE,A Plan of the English Commerce

SOMETIMES IT SEEMS AS IF everyone’simmigrating to America- sailing-ships on the North Atlantic as thick as watermen’s boats on the Thames, more or less wearing ruts in the sea-lanes-and so, in an idle way, Enoch supposes that his appearance on the threshold of the Massachusetts Bay Colony Institute of Technologickal Arts will come as no surprise at all to its founder. But Daniel Waterhouse nearly swallows his teeth when Enoch walks through the door, and it’s not just because the hem of Enoch’s cloak knocks over a great teetering stack of cards. For a moment Enoch’s afraid that some sort of apoplectic climax is in progress, and that Dr. Waterhouse’s final contribution to the Royal Society, after nearly a lifetime of service, will be a traumatically deranged cardiac muscle, pickled in spirits of wine in a crystal jug. The Doctor spends the first minute of their interview frozen halfway between sitting and standing, with his mouth open and his left hand on his breastbone. This might be the beginnings of a courteous bow, or a hasty maneuver to conceal, beneath his coat, a shirt so work-stained as to cast aspersions on his young wife’s diligence. Or perhaps it’s a philosophick enquiry, viz. checking his own pulse-if so, it’s good news, because Sir John Floyer just invented the practice, and if Daniel Waterhouse knows of it, it means he’s been keeping up with the latest work out of London.

Enoch takes advantage of the lull to make other observations and try to judge empirically whether Daniel’s as unsound as the faculty of Harvard College would have him believe. From the Doctors’ jibes on the ferry-ride, Enoch had expected nothing but cranks and gears. And indeed Waterhouse does have a mechanic’s shop in a corner of the-how will Enoch characterize this structure to the Royal Society? “Log cabin,” while technically correct, calls to mind wild men in skins. “Sturdy, serviceable, and in no way extravagant laboratory making ingenious use of indigenous building materials.” There. But anyway, most of it is given over not to the hard ware of gears, but to softer matters: cards. They are stacked in slender columns that would totter in the breeze from a moth’s wings if the columns had not been jammed together into banks, stairways, and terraces, the whole formation built on a layer of loose tiles on the dirt floor to (Enoch guesses) prevent the card-stacks from wicking up the copious ground-water. Edging farther into the room and peering round a bulwark of card-stacks, Enoch finds a writing-desk stocked with blank cards. Ragged gray quills project from inkpots, bent and broken ones crosshatch the floor, bits of down and fluff and cartilage and other bird-wreckage form a dandruffy layer on everything.
