It would have been nothing more than a passing freak of Creation, like a comet, except that Eliza grabbed Jack’s hand and pulled him along, so that they became part of that neighborhood for half an hour, as it rolled and nudged its way among the buildings of Amsterdam like a blob of mercury feeling its way through a wooden maze. Jack saw that they were anticipating news, not from some external source, but from within- information, or rumors of it, surged from one end of this crowd to the other like waves in a shaken rug, with just as much noise, movement, and eruption of debris as that would imply. Like smallpox, it was passed from one person to the next with great rapidity, usually as a brief furious exchange of words and numbers. Each of these conversations was terminated by a gesture that looked as if it might have been a handshake, many generations in the past, but over time had degenerated into a brisk slapping-together of the hands. When it was done properly it made a sharp popping noise and left the palm glowing red. So the propagation of news, rumors, fads, trends, amp;c. through this mob could be followed by listening for waves of hand-slaps. If the wave broke over you and continued onwards, and your palm was not red, and your ears were not ringing, it meant that you had missed out on something important. And Jack was more than content to do so. But Eliza could not abide it. Before long, she had begun to ride on those waves of noise, and to gravitate towards places where they were most intense. Even worse, she seemed to understand what was going on. She knew some Spanish, which was the language spoken by many of these persons, especially the numerous Jews among them.

Eliza found lodgings a short distance south and west of the Damplatz. There was an alley just narrow enough for Jack to touch both sides of it at one time, and someone had tried the experiment of throwing a few beams across this gap, between the second, third, and fourth stories of the adjoining buildings, and then using these as the framework of a sort of house. The buildings to either side were being slurped down into the underlying bog at differing rates, and so the house above the alley was skewed, cracked, and leaky. But Eliza rented the fourth story after an apocalyptic haggling session with the landlady (Jack, who had been off stabling Turk, only witnessed the final half-hour of this). The landlady was a hound-faced Calvinist who had immediately recognized Eliza as one who was predestined for Hell, and so Jack’s arrival and subsequent loitering scarcely made any impression. Still, she imposed a strict rule against visitors-shaking a finger at Jack so that her silver rings clanked together like links in a chain. Jack considered dropping his trousers as proof of chastity. But this trip to Amsterdam was Eliza’s plan, not Jack’s, and so he did not consider it meet to do any such thing. They had a place, or rather Eliza did, and Jack could come and go via rooftops and drainpipes.

They lived in Amsterdam for a time.

Jack expected that Eliza would begin to do something, but she seemed content to while away time in a coffee-house alongside the Damplatz, occasionally writing letters to the Doctor and occasionally receiving them. The moving neighborhood of anxious people brushed against this particular coffee-house, The Maiden, twice a day-for its movements were regular. They gathered on the Dam until the stroke of noon, when they flocked down the street to a large courtyard called the Exchange, where they remained until two o’clock. Then they spilled out and took their trading back up to the Dam, dividing up into various cliques and cabals that frequented different coffee-houses. Eliza’s apartment actually straddled an important migration-route, so that between it and her coffee-house she was never out of earshot.

Jack reckoned that Eliza was content to live off what they had, like a Gentleman’s daughter, and that was fine with Jack, who enjoyed spending more than getting. He in the meantime went back to his usual habit, which was to spend many days roaming about any new place he came into, to learn how it worked. Unable to read, unfit to converse with, he learned by watching-and here there was plenty of excellent watching. At first he made the mistake of leaving his crutch behind in Eliza’s garret, and going out as an able-bodied man. This was how he learned that despite all of those Hollandganger coming in from the East, Amsterdam was still ravenous for labor. He hadn’t been out on the street for an hour before he’d been arrested for idleness and put to work dredging canals-and seeing all the muck that came off the bottom, he began to think that the Doctor’s story of how small creatures got buried in river-bottoms made more sense than he’d thought at first.

When the foreman finally released him and the others from the dredge at day’s end, he could hardly climb up onto the wharf for all the men crowded around jingling purses of heavy-sounding coins: agents trying to recruit sailors to man those ships on the Ij. Jack got away from them fast, because where there was such a demand for sailors, there’d be press-ganging: one blunder into a dark alley, or one free drink in a tavern, and he’d wake up with a headache on a ship in the North Sea, bound for the Cape of Good Hope, and points far beyond.

The next time he went out, he bound his left foot up against his butt-cheek, and took his crutch. In this guise he was able to wander up and down the banks of the Ij and do all the looking he wanted. Even here, though, he had to move along smartly, lest he be taken for a vagrant, and thrown into a workhouse to be reformed.

He knew a few things from talking to Vagabonds and from examining the Doctor’s expansive maps: that the Ij broadened into an inland sea called Ijsselmeer, which was protected from the ocean by the island called Texel. That there was a good deep-water anchorage at Texel, but between that island and Ijsselmeer lay broad sand-banks that, like the ones at the mouth of the Thames, had mired many ships. Hence his astonishment at the size of the merchant fleet in the Ij: he knew that the great ships could not even reach this point.

They had driven lines of piles into the bottom of the Ij to seal off the prongs of the U and prevent French or English warships from coming right up to the Damplatz. These piles supported a boardwalk that swung across the harbor in a flattened arc, with drawbridges here and there to let small boats-ferry kaags, Flemish pleyts, beetle-like water-ships, keg-shaped smakschips-into the inner harbor; the canals; and the Damrak, which was the short inlet that was all that remained of the original river Amstel. Larger ships were moored to the outside of this barrier. At the eastern end of the Inner Harbor, they’d made a new island called Oostenburg and put a shipyard there: over it flew a flag with small letters O and C impaled on the horns of a large V, which meant the Dutch East India Company. This was a wonder all by itself, with its ropewalks-skinny buildings a third of a mile long-windmills grinding lead and boring gun-barrels, a steam-house, perpetually obnubilated, for bending wood, dozens of smoking and clanging smithys including two mighty ones where anchors were made, and a small tidy one for making nails, a tar factory on its own wee island so that when it burnt down it wouldn’t take the rest of the yard with it. A whole warehouse district of its own. Lofts big enough to make sails larger than any Jack had ever seen. And, of course, skeletons of several big ships on the slanted ways, braced with diagonal sticks to keep ’em from toppling over, and all aswarm with workers like ants on a whale’s bones.

Somewhere there must’ve been master wood-carvers and gilders, too, because the stems and sterns of the V.O.C. ships riding in the Ij were decorated like Parisian whorehouses, with carved statues covered in gold-leaf: for example, a maiden reclining on a couch with one shapely arm draped over a globe, and Mercury swooping down from on high to crown her with the laurel. And yet just outside the picket of windmills and watch-towers that outlined the city, the landscape of pastures and ditches resumed. Mere yards from India ships offloading spices and calico into small boats that slipped through the drawbridges to the Damrak, cattle grazed.
