“What embarrassed you in Plymouth inns, may enrich you here, a few miles north,” said the Earl.

“It does not seem a propitious location,” Daniel said. “The poor folk who lived here could not even keep their roof off the floor.”

“No one lived here-this was what the Old Men call a jews-house. It means that there was a lode nearby,” said the Earl.

Newcomen added, “Over yonder by that little brook I saw the ruins of a trip-hammer, for crushing the shode.” Having got his pipe lit, he thrust his free hand into a pocket and pulled out a black stone about the size of a bun. He let it roll into Daniel’s hand. It was heavy, and felt colder than the air. “Feel its weight, Dr. Waterhouse. That is black tin. Such was brought here, where we are standing, and melted in a peat-fire. White tin ran out the bottom into a box hewn from granite, and when it cooled, what came out was a block of the pure metal.”

The Earl had his pipe blazing now too, which gave him a jovial, donnish affect, in spite of the fact that (1) he was all of twenty-three years old, and (2) he was wearing clothes that had gone out of fashion three hundred years ago, and furthermore was bedizened with diverse strange ancient artifacts, viz. some heraldic badges, a tin peat-saw, and a tiny bavin of scrub-oak twigs. “This is where I enter into it, or rather my predecessors do,” he remarked. “The block tin would be packed down the same sort of appalling road we just came up, to one of the four Stannary towns.” The Earl paused to grope among the clanking array of fetishes dangling from chains round his neck, and finally came up with a crusty old chisel-pointed hammer which he waved menacingly in the air-and unlike most Earls, he looked as if he might have actually used a hammer for some genuine purpose during his life. “The assayer would remove a corner from each block, and test its purity. An archaic word for ‘corner’ is ‘coign,’ whence we get, for example, ‘quoin’-”

Daniel nodded. “The wedge that gunners use, aboard ship, to elevate a cannon, is so called.”

“This came to be known as quoinage. And thence, our queer English word ‘coin,’ which bears no relation to any French or Latin words, or German. Our Continental friends say, loosely translated, ‘a piece of money,’ but we English-”

“Stop.”

“Is my discourse annoying to you, Dr. Waterhouse?”

“Only insofar as I like you, Will, and have liked you since I met you as a lad. You have always seemed of a level head. But I fear you are going the way of Alchemists and Autodidacts now. You were about to declare that English money is different, and that its difference inheres in the purity of the metal, and is signified in the very word ‘coin.’ But I assure you that Frenchmen and Germans know what money is. And to think otherwise is to let Toryism overcome sound judgment.”

“When you put it that way, it does sound a bit silly,” the Earl said, cheerfully enough. Then he mused, “Perhaps that is why I have felt it necessary to make this journey with a blacksmith on one hand, and a sixty-seven-year-old Doctor on the other-to lend some gravity to the proposal.”

By gestures so subtle and tasteful that they were almost subliminal, the Earl led them to understand that it was time they were underway. They returned to the coach, though the Earl lingered for a few moments on the running board to exchange civil words with a small posse of gentleman riders who had just come up out of the Gorge and recognized the arms painted on the carriage door.

For a quarter of an hour they trundled along in silence, the Earl gazing out an open window. The horizon was far away, smooth and gently varying except where it was shattered by peculiar hard shapes: protruding rocks, called Tors, shaped variously like schooners or Alchemists’ furnaces or fortress-ramparts or mandibles of dead beasts.

“You put a stop to my discourse and quite rightly, Dr. Waterhouse. I was being glib,” said the young Earl. “But there is nothing glib about this Dartmoor landscape, or would you disagree?”

“Plainly not.”

“Then let the landscape say eloquently what I could not.”

“What is it saying?”

By way of an answer, Will reached into a breast-pocket and pulled out a leaf of paper covered with writing. Angling this toward the window, he read from it. “The ancient tumuli, pagan barrows, Pendragon-battlegrounds, Druid-altars, Roman watch-towers, and the gouges in the earth wrought by the Old Men progressing west-to-east across the land, retracing the path of the Great Flood in their search for tin; all of it silently mocks London. It says that before there were Whigs and Tories, before Roundheads and Cavaliers, Catholics and Protestants-nay, before Normans, Angles, and Saxons, long before Julius C?sar came to this island, there existed this commerce, a deep subterranean flow, a chthonic pulse of metal through primeval veins that grew like roots in the earth before Adam. We are only fleas gorging our petty appetites on what courses through the narrowest and most superficial capillaries.” He looked up.

“Who wrote that?” Daniel asked.

“I did,” said Will Comstock.

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.
