SO MANY BOULDERS PROTRUDED through the moth-eaten tarp of dirt stretched over this land, that they had to stop and alight from the carriage, which had become more trouble than it was worth. They must either walk, or ride on arguably domesticated Dartmoor ponies. Newcomen walked. Daniel elected to ride. He was ready to change his mind if the pony turned out to be as ill-tempered as it looked. The ground underfoot was a wildly treacherous composite of boulders, and grass-tufts as soft as goose-down pillows. The pony’s attention was so consumed by deciding, from moment to moment, where it should place all four of its hooves, that it seemed to forget there was an old man on its back. The track ran north parallel to a small water-course below and to their left. It was only visible about a third of the time, but helpfully marked out by a breadcrumb-trail of steaming horse-patties left by those who had gone before them.

The stone walls that rambled over this land were so old that they were shot through with holes where stones had fallen out, and their tops, far from running straight and level, leaped and faltered. He would phant’sy he was in an abandoned country if it weren’t for the little pellets of sheep dung rolling away under Newcomen’s footsteps and crunching beneath the soles of his boots. On certain hilltops grew spruce forests, as fine and dense and soft-looking as the pelts of Arctic mammals. When the wind gusted through these, a sound issued from them that was like icy water hurrying over sharp stones. But most of the land was covered with heather, gone scab-colored for the winter. There the wind was silent, except for the raucous buller that it made as it banged around in the porches of Daniel’s ears like a drunk burglar.

Of a sparse line of Tors stretching north over the horizon, Crockern was the smallest, humblest, and most convenient to the main road—which was probably why it had been chosen. It looked not so much like a Tor as like the stump and the crumbs left behind after a proper Tor had been chopped down and hauled away. They broke out onto the top of the moor and saw it above them. The men and horses huddling in its lee enabled them to judge its size and distance: farther away and higher up-hill than they had hoped, as was the case with all hard-to-reach destinations. It felt as though they had toiled for hours, and got nowhere, but when Daniel turned around and looked back at the way they had come, its many long meanders, which he had hardly noticed at the time, were all compressed so that they looked like the fingers of two interlaced fists.

The Tors were out-croppings of layered rocks of the kind that Leibniz thought were built up in riverbeds. Wind had eaten out soft layers to make them flattened lozenges piled atop each other in teetering stacks that leaned together for support—like piles of time-rounded books made in a library by a scholar who was trying to find something. Remnants of fallen ones were scattered down-hill for some distance, half-sunk into the ground at crazy angles, like three-volume treatises hurled into the ground in disgust. The wind only became stronger as they went up; small brown birds flapped their wings as hard as they could and yet fell behind this invisible currency in the air, so that they moved slowly backwards past Daniel.

Daniel estimated that two hundred and fifty gentlemen had answered the Earl’s summons, and gathered in the lee of the Tor. But in this place, that many men seemed like ten thousand. Few of them had bothered to dismount. For whatever sort of folk their forebears might have been, these truly were modern gentlemen, and they were as out of their rightful place, here, as Daniel was. The only man who seemed at home was the blacksmith, Thomas Newcomen, who looked like a chip off the old Tor as he stood to the side, broad shoulders an umbrella against the wind, scabby hands in pockets. Daniel saw him now for what he was, a Dwarf out of some Saxon ring-saga.

Between Stones and Wind this Tor ought by right to be dominated by elements of Earth and Air, if he were disposed to think like an Alchemist; but to him it seemed more a watery place. The wind sucked heat from his body as swiftly as snow-melt. The air (compared to the miasmas of cities) had a clarity and cleanliness, and the landscape a washed, lapidary quality, that made him feel as if he were standing on the bottom of a clear New England river at the moment when the ice broke up in the spring. So Water it was; but the presence of Thomas Newcomen spoke of Fire as well, for a Dwarf was never far from his Forge.

“Do not mistake me, I would fain be of service to the Proprietors of the Engine for Raising Water by Fire,” Daniel had insisted, on the twelfth day of Christmas, after Newcomen had stoked the boiler, and the Engine he had wrought, sucking and hissing like a dragon, had begun to pump water up out of Lostwithiel’s mill-pond, and into a cistern on the roof of his house. “But I do not have money.”

“Consider that stop-cock by which Mr. Newcomen brings the machine to life,” the Earl had said, pointing to a hand-forged valve-wheel mounted on a pipe. “Does that stop-cock make steam?”

“Of course not. Steam is generated in the boiler.”

“The trade of this country is a boiler that raises all the steam—which is to say, all the capital—we require. What is wanted is a valve,” the Earl had said, “a means of conducting some of that capital into an engine where it may do something useful.”

THE JUMBLE OF SHRUGGED-OFF slabs afforded natural benches, podia, lecterns, and balconies that served the tin-men as well as the same furnishings in a proper meeting-house. The Court of Stannary was convened there, as it had been for half a millennium, by reading certain decrees of King Edward I. Immediately the most senior of the gentleman of this Tin Parliament stepped forward and proposed that they adjourn, without delay, to a certain nearby Inn, the Saracen’s Head, where (Daniel inferred) refreshments were to be had. This was proposed without the least suspicion that it would be refused. ’Twas like the moment at a wedding when the Priest polls the congregation for objections to the union. But the Earl of Lostwithiel astonished them all by refusing.

He had been seated on a mossy bench of stone. Now he clambered up onto it and delivered the following remarks.

“His Majesty King Edward I decreed that this Court meet in this place, and it has been phant’sied ever since that he did simply thrust the royal finger at a Map, indicating a place equidistant from the four Stannary Towns that surround the Moor, and never suspecting that by so doing he was choosing one of the most remote and horrible places in Britain. And so it is customary to adjourn to the comforts of Tavistock, on the supposition that the King of yore would never have intended for his gentlemen to hold their deliberations in a place like this. But I give King Edward I more credit. I daresay that he had a suspicion of Courts and Parliaments and that he wanted his Tin-men to spend their days in producing metal and not in carrying on tedious disputes, and perhaps forming Cabals. So he chose this place by design, to shorten our deliberations. I say that we ought to remain here, and profit from the King’s wisdom. For the tin and copper trades have fallen on hard times, the mines are flooded, and we have no real business to transact, other than what we gin up. I mean to gin some up now, and to go about it directly.

“My grandfather was John Comstock, the Earl of Epsom, and the scion of that branch of our ancient line, known vulgarly as the Silver Comstocks. As you know he came to ruin, and my father, Charles, fared little better, and even had to leave over the Earldom and immigrate to America when James I was overthrown. I make no bones about my ancestors.

“But even those of you who suppose that we are Jacobites (which we are not) and call us inveterate Tories (which we are) and who say that Queen Anne made me an Earl, only to pack the House of Lords with Tories when she needed to break Marlborough’s power (which may be true)—I say, even those among you who think nothing of me and my line, except what is deprecating and false, must know of the Royal Society. And if you think well of that Society and its works—as every sapient gentleman must—you may not take it amiss, if I remind you of the old connexions between that Society and my grandfather. John Comstock, though wedded to many of the old ways, was also a forward-thinking Natural Philosopher, who introduced the manufacture of gunpowder to England, and whose great distinction it was to serve as the first President of the Royal Society. During the Plague Year he succoured them as well, by offering them refuge on his estate at Epsom, where discoveries too many to list were made by John Wilkins, by the late Robert Hooke, and by him who stands at my right hand: Dr. Daniel Waterhouse, Fellow of Trinity College, Cambridge, Fellow of the Royal Society, and Chancellor of the Massachusetts Bay Colony Institute of Technologickal Arts. Dr. Waterhouse has very recently re-crossed the Atlantic and is even now on his way to London to confer with Sir Isaac Newton…”

The mention of Daniel’s name caused a sparse ripple of curiosity to propagate through the company of cold, irritable Gentlemen. The mention of Isaac’s created a sensation. Daniel suspected this had less to do with Isaac’s invention of the calculus than with the fact that he was running the Mint. The suspicion was confirmed by the next words of William Comstock, Earl of Lostwithiel: “It has been years since silver coins were to be seen in the market-places of this land. As many as are minted are taken to the furnaces of the money-goldsmiths and made over into bullion and sent into the East. Golden guineas are the currency of England now; but that is too great a denomination for common folk to use in their dealings. Smaller coins are wanted. Will they be minted of copper? Or of tin?”

“Copper,” shouted a few voices, but they were immediately drowned out by hundreds shouting, “Tin!”

“Never mind, never mind, ’tis no concern of ours, for our mines will not produce!” proclaimed the Earl. “Else, we would have never so much to talk about. To the Saracen’s Head we should adjourn, so as not to starve or freeze during our deliberations. But as all of our mines are flooded with water, the copper, or the tin, for the next English coinage shall perforce be imported from abroad. ’Twill be of no concern and no profit to us. The doings of this ancient Parliament shall remain a mere antiquarian curiosity; and so why not convene for a few ticks of the clock on a freezing moor, and have done with it?

“Unless—gentlemen—we can pump the water out of our mines. I know how you will object, saying, ‘Nay, we have tried man-engines, horse-engines, mill-wheels and windmills, none of them profit us!’ Even though I am not a miner, gentlemen, I understand these facts. One who understands them better is this fellow standing at my left hand, Mr. Thomas Newcomen, of Dartmouth, who being an humble man styles himself blacksmith and ironmonger. Those of you who have bought mining-tools from him know him thus. But I have seen him work on mechanical prodigies that are, to a mining-pick, as the Concertos of Herr Handel are to the squeaking of a rusty wheel, and I recognize him by the title of Engineer.

“Now, those of you who have seen the apparatus of Mr. Savery may hold a low opinion of engines for raising water by fire; but that of Mr. Newcomen, though it comes under the same patent as Mr. Savery’s, works on altogether different principles—as is evidenced by the fact that it works. Dr. Waterhouse is plucking at my sleeve, I can keep him quiet no longer.”

This came as a surprise to Daniel, but he did in fact find something to say. “During the Plague Year I tutored this man’s father, the young Charles Comstock, in Natural Philosophy, and we spent many hours studying the compression and rarefaction of gases in the engines conceived by Mr. Boyle, and perfected by Mr. Hooke; the lesson was not lost on young Charles; two score years later he passed it on to young Will at their farm in Connecticut, and it was my very great pleasure to visit them there, from time to time, and to witness those lessons being taught so perfectly that no Fellow of the Royal Society could have added what was wanting, nor subtracted what was false. Will took up those lessons well. Fate returned him to England. Providence supplied him with a lovely Devonshire wife. The Queen gave him an Earldom. But it was Fortune, I believe, that brought him together with the Engineer, Mr. Newcomen. For in the Engine that Newcomen has fabricated at Lostwithiel, the seed that was planted at Epsom during the Plague, England’s darkest hour, has flourished into a tree, whose branches are now bending ’neath the burgeoning weight of green Fruit; and if you would care to eat of it, why, all you need do is water that Tree a little, and presently the apples shall fall into your hands.”

From this, most of the gentlemen understood that they were about to be dunned for Contributions, or, as they were styled in those days, Investments. Between that, and hypothermia, and saddle-sores, the response was more tepid than it might have been. But Will Comstock had their attention. “Now one may see why I did not adjourn this Court to the Saracen’s Head. Our purpose is to set prices, and transact other business relating to tin-quoinage. And as the Old Men were exempt in several ways from Common Law, and common taxation, this Court has long met to supersede and overrule the ones that held sway over the rest of England. Without capital, Mr. Newcomen’s engine will remain nothing more than a curiosity that fills my cistern. The mines shall remain inundated. Neither copper nor tin shall come out of them, and this Court shall lose standing, and have no business to transact. On the other hand, if there is some interest among you Gentlemen of Devon—to speak plainly, if a few of you would care to purchase shares in the joint stock company known as the Proprietors of the Engine for Raising Water by Fire—why, then, the bleak situation I have just described is overturned, you shall have purchased a Revolution, and this Court will be a busy one indeed, with little choice but to adjourn to that merry Inn down the road—where, by the way, the first two rounds of drinks will be paid for by your humble and obedient servant.”
