  "Ah, yes, Rudwick," Mallory muttered, then hesitated. "Hardly your new-principle man, Rudwick…"

  Douglas and Chesterton were watching him with open curiosity.

  "We were both paleontologists," Mallory said, suddenly uncomfortable, "but the fellow fancied himself gentry of a sort. Put on fine airs and entertained outmoded theories. Rather muddy in his thinking, in my opinion."

  The two mechanics looked doubtful.

  "I'm not one to speak ill of the dead," Mallory assured them. "Rudwick had his friends, I've mine, and there's an end to it."

  "You do remember," Godwin persisted, "Professor Rudwick's great flying reptile?"

  "Quetzalcoatlus," Mallory said. "Indeed, that was a coup; one can't deny it."

  "They've studied its remains in Cambridge," Godwin said, "at the Institute of Engine Analytics."

  "I plan to do a bit of work there myself, on the Brontosaurus," Mallory said, unhappy with the direction the conversation seemed to be taking.

  "You see," Godwin continued, "the cleverest mathematicians in Britain were snug there, spinning their great brass, while you and I froze in the mud of Wyoming. Pecking holes in their cards to puzzle out how a creature of such a size could fly."

  "I know about the project," Mallory said. "Rudwick published on the topic. But 'pneumo-dynamics' isn't my field. Frankly, I'm not sure there's much to it, scientifically. It seems a bit… well… airy, if you follow me." He smiled.

  "Great practical applications, possibly," Godwin said. "Lord Babbage himself took a hand in the analysis."

  Mallory thought about it. "I'll concede there's likely something to pneumatics, then, if it's caught the eye of the great Babbage! To improve the art of ballooning, perhaps? Balloon-flight, that's a military field. There's always ample funding for the sciences of war."

  "No, sir; I mean in the practical design of machinery."

  "A flying machine, you mean?" Mallory paused. "You're not trying to tell me this vehicle of yours can fly, are you?"

  The mechanics laughed politely. "No," Godwin said, "and I can't say that all that airy Engine-spinning has come to much, directly. But we now understand certain matters having to do with the behavior of air in motion, the principles of atmospheric resistance. New principles, little-known as yet."

  "But we mechanics," said Mr. Chesterton proudly, " 'ave put 'em to practical use, sir, in the shaping of our Zephyr."

  " 'Line-streaming,' we call it," Tom said.

  "So you've 'line-streamed' this gurney of yours, eh? That's why it looks so much like, er…"

  "Like a fish," Tom said.

  "Exactly," said Godwin. "A fish! It's all to do with the action of fluids, you see. Water. Air. Chaos and turbulence! It's all in the calculations."

  "Remarkable," Mallory said. "So I take it that these principles of turbulence—"

  A sudden blistering racket erupted from a neighboring stall. The walls shook and a fine sifting of soot fell from the ceiling.

  "That'll be the Italians," Godwin shouted. "They've brought in a monster this year!"

  "Makes a mortal hogo of a stink!" Tom complained.

  Godwin cocked his head. "Hear them try-rods clacking on the down-stroke? Bad tolerances. Slovenly foreign work!" He doffed his cap and dusted soot against his knee.

  Mallory's head was ringing. "Let me buy you a drink!" he shouted.

  Godwin cupped his ear blankly. "What?"

  Mallory pantomimed; lifted a fist to his mouth, with his thumb cocked. Godwin grinned. He had a quick, bellowed word with Chesterton, over the blueprints. Then Godwin and Mallory ducked out into the sunshine.

  "Bad try-rods," the guard outside said smugly. Godwin nodded, and handed the man his leather apron. He took a plain black coat, instead, and traded his engineer's cap for a straw wide-awake.

  They left the racing-enclosure. "I can only spare a few minutes," Godwin apologized. " 'The Master's eye melts the metal,' as they say." He hooked a pair of smoked spectacles over his ears. "Some of these hobbyists know me, and might try to follow us… But never mind that. It's good to see you again, Ned. Welcome back to England."

  "I won't keep you long," Mallory said. "I wanted a private word or two. About the boy, and such."

  "Oh, Tom's a fine lad," said Godwin. "He's learning. He means well."

  "I hope he'll prosper."

  "We do our best," Godwin said. "I was sorry to hear from Tom about your father. Him taking so ill, and all."

  " 'Ould Mallory, he won't a-go till he's guv away his last bride,' " Mallory quoted, in his broadest Sussex drawl. "That's what Father always tells us. He wants to see all his girls married. He's a game sort, my poor old dad."

  "He must take great comfort in a son like yourself," Godwin said. "So, how does London suit you? Did you take the holiday train?"

  "I've not been in London. I've been in Lewes, with the family. Rode the morning train from there to Leatherhead; then I tramped it."

  "You walked to the Derby from Leatherhead? That's ten miles or more!"

  Mallory smiled. "You've seen me tramp twenty, cross-country in the badlands of Wyoming, hunting fossils. I'd a taste to see good English countryside again. I'm only just back from Toronto, with all our crates of plastered bones, while you've been here for months, getting your fill of this." He waved his arm.

  Godwin nodded. "What do you make of the place, then—now you're home again?"

  "London Basin anticline," Mallory said. "Tertiary and Eocene chalk-beds, bit of modern flinty clay."

  Godwin laughed. "We're all of us modern flinty clay… Here we go, then; these lads sell a decent brew."

  They walked down a gentle slope to a crowded dray laden with ale-kegs. The proprietors had no huckle-buff. Mallory bought a pair of pints.

  "It was good of you to accept our invitation," Godwin said. "I know that you're a busy man, sir, what with your famous geologic controversies and such."

  "No busier than yourself," Mallory said. "Solid engineering work. Directly practical and useful. I envy that, truly."

  "No, no," said Godwin. "That brother of yours, he thinks the world of you. So do we all! You're the coming man, Ned. Your star is rising."

  "We had excellent luck in Wyoming, certainly," Mallory said. "We made a great discovery. But without you and your steam-fortress, those red-skins would have made short work of us."

  "They weren't so bad, once they cozied up and had a taste of whiskey."

  "Your savage respects British steel," Mallory said. "Theories of old bones don't much impress him."

  "Well," Godwin said, "I'm a good Party man, and I'm with Lord Babbage. 'Theory and practice must be as bone and sinew.' "

  "That worthy sentiment calls for another pint," said Mallory. Godwin wanted to pay. "Pray allow me," Mallory said. "I'm still spending my bonus, from the expedition."

  Godwin, pint in hand, led Mallory out of ear-shot of the other drinkers. He gazed about carefully, then doffed his specs and looked Mallory in the eye. "Do you trust in your good fortune, Ned?"

  Mallory stroked his beard. "Say on."

  "The touts are quoting odds of ten-to-one against our Zephyr. "

  Mallory chuckled. "I'm no gambler, Mr. Godwin! Give me solid facts and evidence, and there I'll take my stand. But I'm no flash fool, to hope for unearned riches."

  "You took the risk of Wyoming. You risked your very life."

  "But that depended on my own abilities, and those of my colleagues."

  "Exactly!" Godwin said. "That's my own position, to the very letter! Listen a moment. Let me tell you about our Brotherhood of Vapor Mechanics."

  Godwin lowered his voice. "The head of our trades-union, Lord Scowcroft… He was simple Jim Scowcroft in the bad old days, one of your popular agitators, but he made his peace with the Rads. Now he's rich, and been to Parliament and such; a very clever man. When I went to Lord Scowcroft with my plans for the Zephyr, he spoke to me just as you did now: facts and evidence. 'Master first-degree Godwin,' he says, 'I can't fund you with the h
ard-earned dues of our Brothers unless you can show me, in black and white, how it shall profit us.'

  "So I told him: 'Your Lordship, the construction of steam-gurneys is one of the nicest luxury trades in the country. When we go to Epsom Downs, and this machine of ours leaves the competitors eating her dust, the gentry will stand in queues for the famous work of the Vapor Mechanics.' And that's how it will be, Ned."

  "If you win the race," Mallory said.

  Godwin nodded somberly. "I make no cast-iron promises. I'm an engineer; I know full well how iron can bend, and break, and rust, and burst. You surely know it too, Ned, for you saw me work repair on that blasted steam-fortress till I thought I should go mad… But I know my facts and figures. I know pressure differentials, and engine duty, and crank-shaft torque, and wheel diameters. With disaster barred, our little Zephyr will breeze past her rivals as if they were stock-still."

  "It sounds splendid. I'm glad for you." Mallory sipped his ale. "Now tell me what should happen if disaster strikes?"

  Godwin smiled. "Then I lose, and am left penniless. Lord Scowcroft was liberal, by his own lights, but there are always extra costs in such a project. I've put everything in my machine: my expedition bonus from the Royal Society, even a small bequest I had of a maiden aunt, God rest her."

  Mallory was shocked. "Everything?"

  Godwin chuckled dryly. "Well, they can't take what I know, can they? I shall still have my skills; mayhap I'd undertake another Royal Society expedition. They pay well enough. But I'm risking all I have in England. It's fame or famine, Ned, and naught between."

  Mallory stroked his beard. "You startle me, Mr. Godwin. You always seemed such a practical man."

  "Dr. Mallory, my audience today is the very cream of Britain. The Prime Minister is here today. The Prince Consort is in attendance. Lady Ada Byron is here, and betting lavishly, if rumor's true. When will I have another such chance?"

  "I do follow your logic," Mallory said, "though I can't say I approve. But then, your station in life allows such a risk. You're not a married man, are you?"

  Godwin sipped his ale. "Neither are you, Ned."

  "No, but I have eight younger brothers and sisters, my old dad mortal ill, my mother eaten-up with the rheumatics. I can't gamble my family's livelihood."

  "The odds are ten-to-one, Ned. Fool's odds! They should be five-to-three in Zephyr's favor."

  Mallory said nothing. Godwin sighed. "It's a pity. I dearly wanted to see some good friend win that bet. A big win, a flash win! And I myself can't do it, you see? I wanted to, but I've spent my last pound on Zephyr. "

  "Perhaps a modest wager," Mallory ventured. "For friendship's sake."

  "Bet ten pounds for me," Godwin said suddenly. "Ten pounds, as a loan. If you lose, I'll pay you back somehow, in days to come. If you win, we'll split a hundred pounds tonight, half-and-half. What do you say? Will you do that for me?"

  "Ten pounds! A heavy sum…"

  "I'm good for it."

  "I trust that you are… " Mallory now saw no easy way to refuse. The man had given Tom a place in life, and Mallory felt the debt. "Very well, Mr. Godwin. To please you."

  "You shan't regret it," Godwin said. He brushed ruefully at the frayed sleeves of his frock-coat. "Fifty pounds. I can use it. A triumphant inventor, on the rise in life and such, shouldn't have to dress like a parson."

  "I shouldn't think you'd waste good money on vanities."

  "It's not vanity to dress as befits one's station." Godwin looked him over, sharp-eyed. "That's your old Wyoming tramping-coat, isn't it?"

  "A practical garment," Mallory said.

  "Not for London. Not for giving fancy lectures to fine London ladies with a modish taste in natural-history."

  "I'm not ashamed of what I am," Mallory said stoutly.

  "Simple Ned Mallory," Godwin nodded, "come to Epsom in an engineer's cap, so the lads won't feel anxious at meeting a famous savant. I know why you did that, Ned, and I admire it. But mark my word, you'll be Lord Mallory some day, as surely as we stand here drinking. You'll have a fine silk coat, and a ribbon on your pocket, and stars and medals from all the learned schools. For you're the man dug up the great Land Leviathan, and made wondrous sense from a tangle of rocky bones. That's what you are now, Ned, and you might as well face up to it."

  "It's not so simple as you think," Mallory protested. "You don't know the politics of the Royal Society. I'm a Catastrophist. The Uniformitarians hold sway, when it comes to the granting of tenures and honors. Men like Lyell, and that damned fool Rudwick."

  "Charles Darwin's a Lordship. Gideon Mantell's a Lordship, and his Iguanodon's a shrimp, ranked next to your Brontosaur."

  "Don't you speak ill of Gideon Mantell! He's the finest man of science Sussex ever had, and he was very kind to me."

  Godwin looked down into his empty mug. "I beg your pardon," he said. "I spoke a bit too frankly, I can see that. We're far from wild Wyoming, where we sat about a campfire as simple brother Englishmen, scratching wherever it itched."

  He put his smoked spectacles on. "But I remember those theory-talks you'd give us, explaining what those bones were all about. 'Form follows function.' 'The fittest survive.' New forms lead the way. They may look queer at first, but Nature tests them fair and square against the old, and if they're sound in principle, then the world is theirs." Godwin looked up. "If you can't see that your theory is bone to my sinew, then you're not the man I take you for."

  Mallory removed his cap. "It's I who should beg your pardon, sir. Forgive my foolish temper. I hope you'll always speak to me frankly, Mr. Godwin, ribbons on my chest or no. May I never be so unscientific as to close my eyes to honest truth." He offered his hand.

  Godwin shook it.

  A fanfare rang from across the course, the crowd responding with a rustle and a roar. All around them, people began to move, migrating toward the stands like a vast herd of ruminants.

  "I'm off to make that wager we discussed," Mallory said.

  "I must get back to my lads. Join us after the run? To split the winnings?"

  "Certainly," Mallory said.

  "Let me take that empty pint," Godwin offered. Mallory gave it to him, and walked away.

  Having taken leave of his friend. Mallory instantly regretted his promise. Ten pounds was a stiff sum indeed; he himself had survived on little more per annum, during his student days.

  And yet, he considered, strolling in the general direction of the book-makers' canopied stalls, Godwin was a most exacting technician and a scrupulously honest man. He had no reason whatever to doubt Godwin's estimates of the race's outcome, and a man who wagered handsomely on Zephyr might leave Epsom that evening with a sum equivalent to several years' income. If one were to bet thirty pounds, or forty…

  Mallory had very nearly fifty pounds on deposit in a City bank, the better part of his expedition bonus. He wore an additional twelve in the stained canvas money-belt firmly cinched beneath his waistcoat.

  He thought of his poor father gone feeble with hatter's madness, poisoned by mercury, twitching and muttering in his chair by the hearth in Surrey. A portion of Mallory's money was already allocated for the coal that fed that hearth.

  Still, one might come away with four hundred pounds… But no, he would be sensible, and wager only the ten, fulfilling his agreement with Godwin. Ten pounds would be a sharp loss, but one he could bear. He worked the fingers of his right hand between the buttons of his waistcoat, feeling for the buttoned flap of the canvas belt.

  He chose to place his bet with the thoroughly modern firm of Dwyer and Company, rather than the venerable and perhaps marginally more reputable Tattersall's. He had frequently passed Dwyer's brightly lit establishment in St. Martin's Lane, hearing the deep brassy whirring of the three Engines they employed. He did not care to lay such a wager with any of the dozens of individual book-makers elevated above the throng on their high stools, though they were nearly as reliable as the larger firms. The crowd kept them so; Mallory himself had witness
ed the near lynching of a defaulting betting-man at Chester. He still recalled the grisly shout of "Welsher!" pitched like a cry of "Fire!" going up inside the railed enclosure, and the rush against a man in a black cap, who was buried down and savagely booted. Beneath the surface of the good-natured racing-throng lay an ancient ferocity. He'd discussed the incident with Lord Darwin, who'd likened the action to the mobbing of crows…

  His thoughts turned to Darwin as he queued for the steam-racing wicket. Mallory had been an early and passionate supporter of the man, whom he regarded as one of the great minds of the age; but he'd come to suspect that the reclusive Lord, though clearly appreciating Mallory's support, considered him rather brash. When it came to matters of professional advancement, Darwin was of little use. Thomas Henry Huxley was the man for that, a great social theorist as well as an accomplished scientist and orator…

  In the queue to Mallory's immediate right lounged a swell in subdued City finery, that day's number of Sporting Life tucked beneath an immaculate elbow. As Mallory watched, the man stepped to the wicket and placed a wager of one hundred pounds on a horse called Alexandra's Pride.

  "Ten pounds on the Zephyr, to win," Mallory told the betting-clerk at the steam-wicket, presenting a five-pound note and five singles. As the clerk methodically punched out the wager, Mallory studied the odds arrayed in kino-bits above and behind the glossy faux-marble of the papier-mache counter. The French were heavily favored, he saw, with the Vulcan of the Compagnie Generate de Traction, the driver one M. Raynal. He noted that the Italian entry was in little better position than Godwin's Zephyr. Word of the try-rods?

  The clerk passed Mallory a flimsy blue copy of the card he'd punched. "Very good, sir, thank you." He was already looking past Mallory to the next customer.

  Mallory spoke up. "Will you accept a check drawn on a City bank?"

  "Certainly, sir," the clerk replied, raising one eyebrow as if noticing Mallory's cap and coat for the first time, "provided they are imprinted with your citizen-number."

  "In that case," Mallory said, to his own amazement, "I shall wager an additional forty pounds on the Zephyr."

  "To win, sir?"
