To the other side of the wind-chest was a console looking somewhat like the keyboard of a pipe-organ. But it had only thirty-two keys, with no sharps or flats, and a few of them were stuck down. The organist was a young woman with long cinnamon hair put up in a loose bun. Like every other woman in Bridewell she wore a dress that appeared to have been plucked by a blind man from a parish poor-box; but it was clean and she had obviously devoted many an hour to patching it and taking it in to respect the general shape of her body. As Daniel approached with his guests in train, she sat up straight, reached out, and pulled on an ivory knob. A sigh came from the works and the stuck keys all came unstuck at once.
“Your grace,” Daniel said, turning to Eliza, “I present Miss Hannah Spates. Miss Spates, this is the lady I told you about.”
Hannah Spates rose, and made a pass at a curtsey.
“I am pleased to make your acquaintance,” said Eliza, having instantly donned a sincere but distant affect commonly seen among high-born philanthropists obliged to visit hospitals, orphanages, poor-houses, &c. “Pray, what is this instrument? Are we to hear a performance?”
Hannah was wrong-footed by the words “instrument” and “performance” but soon enough decrypted the question without any aid from Daniel. “It is the card-punching machine, your grace,” she answered, “it cuts the bits out, as I’m to show you.”
“We shall balance the books first,” Daniel announced, and led his guests onwards to a back corner of the room, where a semblance of a banca had been established. There was a large desk, manned by a clerk. Standing behind him was a gentleman of about fifty, who now stepped forward to be introduced. “Mr. William Ham,” Daniel identified him, “my nephew, and the money-goldsmith who tends to our affairs in the City.”
Pleasantries were exchanged; Eliza allowed as how she had heard of Mr. Ham from friends of hers who were pleased to have done business with him, and William Ham made it known how honored he was by this. He seemed startled and pleased to have been recognized at all, as he was a quiet, well-dressed, but indifferent-looking sort, typical of the newish breed who had taken over the banca trade from the menagerie of chandelier-swinging adventurers, intoxicated poltroons, and pathological liars who’d launched it when Daniel had been a young man.
To business: Daniel handed the little box of gold cards to William Ham, who carried them over to a standing-desk by the window and weighed them on a scale. He called out numbers to the clerk, who repeated them aloud and pricked them down in a book. The cards were then placed in a strong-box that squatted on the floor-boards next to the banca. All, that is, save for one of them, which was handed to a third man: an aproned overseer, struck from the same mould as the ones down in the hemp-pounding shop, save that he was not brandishing a cane. With the care and pomp of a priest bearing the consecrated host across a chancel, he took this to the organ-like device, and set it down, for the nonce, on the music stand above the keyboard. Then he gripped a pair of heavy black wrought-iron handles that projected from the machine’s front panel, just above the keyboard, and gave them a mighty jerk. A slab of iron emerged from the machine like a tongue being thrust out. It was flat and smooth as if it had been extruded from a rolling-mill, and for the most part it was devoid of markings or features of any kind. But at the back of it was a shallow square depression perforated by a dense grid of holes, so that it looked like a grille or screen. The overseer plucked the gold card from the music-stand and laid it into the depression, where it fit perfectly and covered up all of the holes with a margin to spare around the edges. Then he put the heels of his hands against the two iron handles and rammed the slab, along with its golden burden, back into the bowels of the machine. As it boomed into place, the discriminating listener could hear a metallic snap, as though some latches had engaged to hold it all in place.
He stepped back. Miss Spates now took up her perch on the bench before the keyboard, and smoothed out her patched skirt. Her first act was to bend forward and peer into a prism mounted on the top of the console. Evidently she did not like what she saw, and so she reached up with both hands and began to turn a pair of iron cranks this way and that, making some adjustment to the position of the pallet. When she was satisfied, she folded her hands demurely in her lap, and looked at Daniel’s knees.
“Here is where I am suffered to play a small rôle,” Daniel remarked, reaching into his breast-pocket and drawing out a card of stiff paper that had been the object of several hours’ or days’ attention from a fine quill-pen. Its edge was decorated with strings of digits and its interior mostly filled with writing in a cramped hand: blocks of text in LATIN and English, runes in the Real Character, and brief outbursts of digits. This he handed, with a suggestion of a bow, to Hannah, who rotated it and set it in place on the music-stand.
“She can read!?” Johann said incredulously.
“Actually, she can—thanks to her doting father—
but this is unusual, and not strictly necessary,” Daniel answered. “All they need to be able to do, is to distinguish between a one and a zero—as you may see for yourself by inspecting the card.”
Johann, Eliza, and Caroline crowded in behind Miss Spates to peer over her shoulders at the specimen on the music-stand. It bore many styles of numbers and characters; but she had oriented it so that she could read a long string of digits printed along the edge. Every one of those digits was either a 1 or a 0. As the others had been talking, she had been sliding a finger along the keyboard, shoving down some keys but not others. Whenever a key was depressed, snicking and clunking noises would sound from some system of rods and levers back inside the mechanism, and the key would stay where she had put it. It was plain to see that the pattern she was making of those keys was the same as the pattern of ones and zeroes written on the edge of the card: wherever she saw a 1, she depressed the corresponding key, and wherever she saw a 0, she skipped over it.
The minute and exacting toil of Miss Spates was accompanied by loud, sweaty, vigorous labor from the bellows-pumping wenches, who had put on a crescendo, trying to stomp the mercury up to the red ribbon. “By your leave, sir,” one of them gasped, “sometimes we sing a song, as sailors do when they heave on a hawser.”
“Pray carry on!” Daniel returned, to the dismay of the overseer who had just opened his mouth to ban it.
Oh have you met Miss Sally Brown
The country’s fairest daughter,
She works the handle up and down,
To pump the farmer’s water
Pumpin’ Sal, pumpin’ Sal,
No one does it like that little gal,
Jump to the pump and work that rod,
And make your fellow a lucky sod!
Sally moved to London Town
And soon became misguided,
She pumped the men who came around,
And sent them home delighted.
Pumpin’ Sal, pumpin’ Sal, [etc.]
Sally lives in Bridewell now
Pumping is her chore ’gain.
She wears her legs out for to power
A Virtuoso’s Organ.
Pumpin’ Sal, pumpin’ Sal, [etc.]
At the final beat, the quicksilver in the tube finally shot up to kiss the ribbon. Hannah Spates hauled back on an ivory knob that she had been gripping in sweaty expectation. The machine hissed, not from one place but from many, like fragments of a burst cannon raining into the sea.
Mounted to the top of the wind-box was a row of what had at first appeared to be organ-pipes. Each was several inches in diameter and a yard long. They were arranged in a segment of an arc whose center was a dense complex of rods and levers atop the console, and whose radius was a couple of yards. The pipes were joined to the console by brass levers that fanned out from the center like rays of the sun. Some of these, but not others, suddenly went into motion.
It now became obvious that pistons were concealed within those cylinders, and some of them were being pressed up by air from the wind-chest. As they moved they elevated th
e ends of the brass levers. Each lever pivoted around an oiled fulcrum that was far from the piston, and close to the central mechanism, giving it a large mechanical advantage at the latter end. The rapid upward thrust of each piston caused the opposite end of its lever to press downward slowly, but with great force; and each of those lever-ends bore down upon a slim vertical rod. The rods were thirty-two in number, arranged in a regular picket-line; each of them resisted movement for a few heart-beats and then gave way, as if some barrier had been breached. This sudden yielding enabled the piston at the opposite end to fly up until it tripped a lever affixed to a vertical pushrod on the outside of its pipe. The pushrod transmitted force down to some air-gate at the base of the pipe, which sprang open, allowing the piston to fall down to its starting-place. It was all over in a few moments. Miss Spates pulled the knob that caused all the keys to pop up to the zero position.
The coda to the performance was a faint skirling noise that emanated from the works for a few seconds. Then a little golden spume jetted from a cavity on the front of the console, and was caught by a porcelain bowl beneath. Daniel snatched this and showed it to the visitors. It contained several tiny disks of gold, like færy-coins, some of which were still spinning and buzzing round on their rims. “These bits,” Daniel said, “are all of a common weight, which means that to weigh them is to count them; the count is then tallied.”
“Tallied in what way?” Johann asked.
“The clerk examines the card,” Daniel said, indicating the snarled document Miss Spates had been reading from, “and checks the sum of each number, to know how many bits ought to have been punched out; if this agrees not with the number of bits in the bowl, the card is in error, and is sent back to be re-melted. A rare occurrence, for Miss Spates does not make Mis-takes!”
Indeed Miss Spates had already reached up to grip a brass lever, and hauled back on it once; this had ratcheted the iron pallet a short distance deeper into the machine, as she verified by a glance into the prism. The bellows-wenches were singing again, and Miss Spates had found a new number on the card, and was registering it upon the keys. In a few moments came another climax of singing, hissing, and clunking; another convulsion of many levers and another rill of golden bits. After several more repetitions, Hannah Spates rose and got out of the way; the bellows-wenches climbed down and headed off in the direction of a beer-bucket; and the overseer stepped in to haul the iron pallet backwards out of the machine. He retrieved the golden card, which had been Swiss-cheesed by scores of neat round holes. Each of these was situated at an intersection of the Grid of Monsieur Descartes; but not all of the intersections had been punched. The result was a curious admixture of order and randomness, perhaps akin to what one would observe in a neatly printed message that was, however, written in some inscrutable cypher.
“My understanding of Clerkenwell Court has been much advanced,” was Eliza’s verdict, “and yet there remains much that is mysterious. I see, for example, why you have recruited organ-makers. But not the man who makes lightning.”
“We bought a stock of parts from a Dutch organ-maker who was returning to his home country, and so this machine was fabricated using the tricks of that trade,” Daniel allowed. “A toy-maker, a horologist, or electrical enthusiast might have reached the same destination, via a different route.”
“But this is not, as I gather, the machine that does the thinking?”
“The Logic Mill will be a different machine entirely,” Daniel said.
“Will be? And so it does not exist yet?”
“The punching of the cards will take a great deal of time, even if we build many more machines like this one, and put all of Bridewell to work,” Daniel said. “Moreover, the Logic Mill cannot be designed, built, or tested, until we have some samples of cards to give it. And so in our work to date we have borne down very hard on the card-punching problem. As you have seen, that problem is solved. Additional machines like this one are now being made; but most of our efforts may now be devoted to the Logic Mill.” Daniel cleared his throat delicately. “A significant infusion of Capital would be most welcome.”
“I should say so!” Johann exclaimed. “Why are you making the cards out of gold?”
“It is ductile, hence easily made into cards of perfectly uniform thickness. Yet it is durable, for it is the only metal that does not rust or tarnish. But that is not why we need capital. Strange to relate, we already have enough gold locked away in our vault to transcribe all of the paper cards that I brought with me.”
“Please say more on that—?” Eliza requested.
“Oh, when I came here from Boston I brought several boxes of these paper cards—enough to inform the logical kernel of a machine.”
“Why did you?”
“Because, madame, the Massachusetts Bay Colony Institute of Technologickal Arts has been generously supported by men of some importance, and I thought they might like to see tangible evidence that I had actually been doing something. No, I did not anticipate any of this.” He extended a hand toward the machine, and followed up with a judicious hooding of the eyelids, and a nod at Caroline.
“There are more cards still in Boston, then?”
“I left almost all of them behind in Massachusetts. But God willing they are at this very moment being loaded into the hold of a ship, Minerva, which I believe is known to you. She sailed from London in late April, and ought to have reached Boston Harbor last week.”
“When Minerva, God willing, returns to London, then you shall have need of more gold for making into cards,” Johann observed.
“By a happy coincidence,” Daniel said with a dry smile, “more gold is expected to reach us, by sea, at the same time. And so when I speak of our need for capital, I am not referring to gold for card-making.”
“As a sort of technologickal adventurer, Doctor, you are suffered, nay encouraged, to imbibe of a sort of optimism that in other disciplines—such as finance—would be reckoned incompetence,” Eliza said. “I am being asked to act as a financier, and can afford myself no such luxury. I say that you are gambling too much on the likelihood that two ships—one freighted with cards, the other with gold—shall arrive in London safely and at the same time.”
“The point is well taken,” Daniel said, “and so let me simplify matters by letting you know that the cards and the gold are on the same ship.”
“Minerva carries both?”
“And I think you know what a fine ship she is. I would sooner trust gold to the bilge of Minerva than the vaults of many a banca. It is safe to predict that, round the beginning of August, she will drop anchor in the Pool, and we shall have all of the requisites to punch a large number of these cards. What is wanted, in the meantime, is financing to sustain the operations of Clerkenwell Court, so that we may build the Logic Mill.”
“May I presume that you have already tried and failed to get additional support from your benefactor?”
“Roger Comstock is the one who proposed that I consult you, madame.”
“I never thought one such as he could run out of money.”
“Properly speaking, it is a question of liquidity. Much now hangs in the political balance, as you know. The perils that have forced Princess Caroline to seek refuge far from the gardens of Hanover, have not failed to press in, almost as hotly, on the Marquis of Ravenscar. He has extended his resources to the utmost, readying and arming himself for the coming struggle against Bolingbroke.”
“And not without effect, if yesterday’s news from Parliament be true,” Johann put in.
“Yesterday was a victory for Comstock—but it was little more than a skirmish. Ahead lie battles.”
“It is a wonder he has time or money for Logic Mills at all,” Johann remarked.
“In truth, he does not, and has quite forgotten about us for now,” Daniel said.
“So you require a sort of bridge loan,” Eliza said.
“Indeed, madame.”
“A bridge-builder cannot practice his trade, unles
s he knows the length of the span to be made—”
“The length is from now until a Hanover is crowned King or Queen of Great Britain.”
“That could be never.”
“And yet, as a wise woman once remarked, we are all gambling on it.”
“It could be years, then.”
“Queen Anne is as likely to live to the end of 1714 as I am to go to Naples and sell myself in the town square as a gigolo,” Daniel averred.
“What is the amount you seek?”
“A stipend, delivered at regular intervals. Mr. Ham has drawn up some figures.”
“That sounds boring,” Eliza said, “and so I propose a parting of the ways. Johann, who has a head for numbers, can look at Mr. Ham’s. Hildegard may wish to stay with him.”
“And you, madame?”
“I have a head for relationships,” Eliza said, “and so I shall join you in my carriage as you are delivered back to Clerkenwell Court, and I shall discourse to you of the relationship—or to be blunt, what precisely is to be my security for the proposed loan.”
