The Difference Engine

Sybil allowed them to get her to her feet. Houston hesitated, seeing it, and there was a light gallant scatter of applause for her. She felt pale, unworthy; she smiled wanly, and shook her head, and wished she were invisible. She leaned her head on the padded shoulder of the man who had taken her pulse. "Sir, if I could go, please," she whispered.

Her rescuer nodded alertly, a little fellow with clever blue eyes. His long greying hair was parted in the middle. "I shall see the lady home," he piped at the others. He shrugged into an opera cape, perched a tall beaver hat on his head, and lent her his arm. They walked together up the aisle, Sybil leaning on him heavily, unwilling to meet anyone's eyes. The crowd was roused, now. For the first time, perhaps, they were listening to Houston as a man, rather than as some sort of queer American exhibit.

Her little gentleman held dingy velvet aside for her as they emerged into the Garrick's chilly foyer, with its flaking gilt cupids and damp-marked faux-marble walls. " 'Tis very kind of you, sir, to help me so," Sybil offered, noting that her escort looked as though he might have money. "Are you a medical man?"

"I was a student once," he said, with a shrug. His cheeks were flushed, twin hot points of red.

"It gives a man a certain air of distinction," Sybil said, not for any particular purpose, but just to fill the silence. "Schooling of that sort, I mean."

"Hardly, madame. I wasted all my time versifying. I must say that you seem fit enough now. Very sorry to hear about that unfortunate brother of yours."

"Thank you, sir." Sybil looked at him sidelong. "I'm afraid it was very forward of me, but General Houston's eloquence earned me away."

He shot her an opaque glance, the look of a man who suspects that a woman is gulling him. "In all honesty," he said, "I do not entirely share your enthusiasm." He coughed explosively into a wadded handkerchief and wiped his mouth. "This London air will be the death of me."

"Nonetheless, I do thank you, sir, though I regret we've not been introduced… "

"Keats," he said, "Mr. Keats." He drew a ticking silver chronometer from his waistcoat, a many-dialed thing the size of a small potato, and consulted it. "I'm not familiar with the district," he said distantly. "I'd thought to hail you a cabriolet, but at this hour…"

"Oh, no, Mr. Keats, thank you, but I shall go by the underground."

His bright eyes widened. No respectable woman rode the underground unescorted.

"But you haven't told me your profession, Mr. Keats," she said, hoping to distract him.

"Kinotropy," Keats said. "The techniques employed here tonight are of some special interest! While the screen's resolution is quite modest, and the refresh-rate positively slow, remarkable effects have been secured, one presumes through algorithmic compression—but I fear that is all a bit technical." He put away his chronometer. "Are you entirely certain you wouldn't rather I attempted to hail a cab? Do you know London well, Miss Jones? I might escort you to the local omnibus stand—'tis a railless carriage, you see… "

"No, sir, thank you. You've been exceptionally kind."

"You're quite welcome," he said, his relief evident as he opened and held one of the half-glass doors to the street. Just then a ski

"I say there! Young man!" Mr. Keats had produced a coin, and Sybil understood that he wished the boy to hail a cab for her, but now the wet eyes gleamed at them with alarm, the pale face hollowed by gaslight. Suddenly he bolted, something dark tumbling from beneath his coat, where it rolled into the gutter. The boy halted and looked warily back at them.

He'd dropped a hat, a top-hat.

He came trotting back, eyes still on them, snatched it up, stuffed it under his coat, and off again, into the shadows, though this time not nearly so rapidly.

" 'Pon my word," Mr. Keats said in disgust, "that fellow's a thief! That water-proof is stuffed with the hats of the audience!"

Sybil could think of nothing to say.

"I imagine the rascal took cruel advantage of that commotion you caused," Keats told her, his tone lightly etched with suspicion. "Pity! One never knows who to trust these days."

"Sir, I do believe I hear the Engine getting up steam for the kinotrope… "

And that was enough for him.

The installation of exhaust-fans, said the Daily Telegraph, had wrought a perceptible improvement in the atmosphere of the Metropolitan, though Lord Babbage himself held that a truly modern underground railway would operate on pneumatic principles exclusively, involving no combustion whatever, rather in the way mail was conveyed throughout Paris.

Seated in a second-class carnage, breathing as shallowly as possible, Sybil knew it all for humbug, or in any case the improvement part, for who knew what marvels the Rads mightn't bring forth? But hadn't the Rad papers also published the testimony of medicals, in the pay of the railroad, that sulphurous fumes were therapeutic for asthma? And it wasn't only the fumes from the Engines, but vile sewer-seepings as well, and gassy leakings from collapsible India-rubber bags, that lit the carriage-jets in their wire-netted glass shades.

It was a queer business, the underground, when you thought about it, racketing along at such speeds, through the darkness under London, where the navvies had come upon lead water-pipes of the Romans, and coins, mosaics, and archways, elephant's teeth a thousand years old…

And the digging went on, this and every night, for she'd heard their great machine huffing, as she'd stood by Mick on the Whitechapel pavement; they worked unceasingly, the excavators, boring newer, deeper lines now, down below the tangle of sewers and gas-pipes and bricked-over rivers. The new lines were shored with steel, and soon Lord Babbage's smokeless trains would slide through them silent as eels, though she found the thought of it somehow unclean.

The lamps flared all at once, the flow of gas disturbed by a particularly sharp jolt, the faces of the other passengers seeming to leap out at her: the sallow gent with something of the successful publican about him, the round-cheeked old Quaker cleric, the drunken dandy with his coat open, his canary waistcoat all dotted down the front with claret…

There were no other women in the carriage.

Farewell to you, sirs, she imagined herself crying, farewell to your London, for she was a 'prentice adventuress now, sworn and true, bound for Paris, though the first leg of the voyage consisted necessarily of the tuppe

But the clergyman had noticed her, his contempt quite open, there for anyone to see.

It was really quite horribly cold, making her way from the station to her room in Flower-and-Dean Street; she regretted her vanity, for having chosen her fine new shawl rather than her mantelet. Her teeth were chattering. Sharp frost shone in pools of gas-light on the street's new macadam.

The cobbles of London were vanishing month by month, paved over with black stuff that poured stinking hot from the maws of great wagons, for navvies to spread and smooth with rakes, before the advance of the steam-roller.

A daring fellow whisked past her, taking full advantage of the gritty new surface. Nearly recumbent within the creaking frame of a four-wheeled velocipede, his shoes were strapped to whirling cranks and his breath puffed explosively into the cold. He was bare-headed and goggled, in a thick striped jersey, a long knit scarf flapping out behind him as he sped away. Sybil supposed him an inventor.
