A lot of fellows were doffing their hats-not to Daniel, of course, but to his traveling-companion. Wren was clearly getting ready to part ways with him. “I have in my possession drawings of many of Hooke’s buildings.”

“That is just the sort of thing I need.”

“I shall send them to you. As well as the names of some men, now retired, who built them, and who may have recollections of peculiarities in their construction.”

“That is really splendid of you.”

“It is the least I can do on behalf of the estate of the fellow who taught me how to design arches. Lastly, I shall nominate you as Overseer of Demonstrations to the Royal Society.”

“I beg your pardon?”

“It will become clear to you with a little reflection. I bid you good day, Dr. Waterhouse.”

“You are a perfect gentle knight, Sir Christopher.”

HE HAD PHANT’SIED that London would be less congested in its eastern reaches, beyond Bishopsgate, but if anything that part of the city was worse yet. For on that front it lay open to the inroads of, on the left hand, Industry, and on the right, Shipping. Neither Daniel nor his carter cared to spend the balance of the day disputing the right-of-way against heavy wagons laden with bricks, coal, and lime, and being drawn down the street by cavalry-charges of draught

–horses. They might cross the Bridge, but Southwark would be the same scene with narrower, fewer, and worse roads. So Daniel decreed a change in plans, and had the carter drive him and his parcels down Fish Street Hill to the approaches of London Bridge, and then east along Thames Street as if going to the Tower. To their right, diverse narrow ancient lanes ran down to the wharves, about a bow-shot away, each street giving him a moment’s glimpse of a different controversy, mob action, or commercial transaction; but the river Thames was not present in any of these tableaux, because all he could see at the open street-ends was masts and rigging.

They passed the Billingsgate market, which was arrayed around the three sides of a large rectangular dock, or cut-out in the riverbank, where small vessels could come in from the Pool. The dock reached most of the way to Thames Street, which broadened into a plaza there, so as to shake hands with the market. Black rocks skittered out, or lodged and shattered, under the iron rims of the cart’s wheels. The horses faltered. They were pushing through a crowd of children in grimy clothes who were buzzing around gleaning those black rocks out of crevices between paving-stones.

“Crimps!” said the carter, “Crimps and Meters come to meet the Hags.” He was referring, not to the boys scavenging coal, but to classes of people doing business on the northern shore of Billingsgate Dock. Crimps were coal-merchants, and to judge from snatches of accent drifting on the breeze, they were Yorkshiremen. Meters were the City of London officials who weighed the chalders of sea-coal on immense blackened steel-yards, and Hags were the stout tubby boats that ferried it in from the big hulks out in the Pool. All of which was new to Daniel, who thought of Billingsgate as a fish-market; but he was reassured to see that the fishwives had not been driven out of the place, indeed still controlled most of the dock, and drove back encroaching Crimps with well-aimed barrages of fish-guts and vivid, faithful descriptions of their persons and their families.

Past Billingsgate the going was easier, but only slightly, as the Customs House was shortly ahead of them on the right. This was so crowded with men doing transactions that it was said by some to rival Change Alley. Their discourse commingled into a surfing roar, and even from here Daniel could hear the occasional crash and foam of some mighty wave of Intercourse.

“This will do,” he said, and the carter took the next right turn and drove down a lane, lined with small and dingy, but very active, business concerns, to the Thames wharf. Several wee docks had been chopped out of this stretch of the riverbank and it did not take them long to find one where watermen were gathered, smoking pipes and exchanging learned commentary. Simply by standing still and dispensing coins to the right people at the right times, Daniel was able to cause his parcels to be loaded on a boat; passage to be booked across and down the river; and the carter to be sent home.

Seen from Thames Street the river had seemed less Conduit than Barrier-a palisade of honed wood thrown up to prevent an invasion, or an escape. But with a few strokes of the waterman’s oar they penetrated the screen along the wharves and surged out into the main channel. This was as crowded as any water in the world, but miraculously open and accommodating compared to the streets of London. Daniel felt as though burdens had been lifted, though nothing could be further from the truth. London very quickly became a smouldering membrane, a reeking tarpaulin flung over the hill and not smoothed out. The only features of consequence were the Fire Monument, the Bridge, the Tower, and St. Paul’s. The Bridge, as always, seemed like a Bad Idea, a city on stilts, and a very old, slumping, inflammable Tudor city at that. Not far from its northern end was the Fire Monument, of which Daniel was now getting his first clear view. It was an immense solitary column put up by Hooke but universally attributed to Wren. During Daniel’s recent movements about London he had been startled, from time to time, to spy the lantern at its top peering down at him from over the top of a building-just as he had often felt, when he was a younger man, that the living Hooke was watching him through a microscope.

The tide was flowing, and it wafted them downstream at a fair clip. They were abreast of the Tower before he knew it. With some effort of will, Daniel swerved his gaze from Traitor’s Gate, and wrenched his thoughts from recollection of old events, and paid heed to present concerns. Though he could not see through the Tower’s walls and bastions, he could see smoke rising from the general vicinity of the Mint buildings; and beneath the general clamor radiating from the city he phant’sied he could detect the slow heavy pulse of the trip-hammers beating out guineas. On the battlements were soldiers, wearing black trim on their red coats: therefore, the Queen’s Own Black Torrent Guards, who had been garrisoned at the Tower, yanked away from it, re-garrisoned there, yanked back again so many times that Daniel had given up trying to keep track. The whereabouts of the Black Torrent Guard were an infallible weather-cock that told which way the wind was blowing, where Marlborough-who had founded the regiment-was concerned. If the United Kingdom was at war, the Black Torrent Guards were at the front. If at peace, and Marlborough in favor with the Sovereign, they would be at Whitehall. If Marlborough lay under suspicion of being another Cromwell-in-the-making, then his favored Regiment would be exiled to the Tower, and numbed with the toils of minding Mint and Arsenal.

As they drifted down the river, the buildings gradually became meaner, and the ships more magnificent. Not that the buildings were so very mean at first. Carriageways had always coursed along both banks, but now one could not see them because warehouses, mostly of burnt brick, had been cast up between them and the river, their walls plunging sheer into the water so that boats could bump against them to be loaded or unloaded with the help of cranes that projected out above the water like the feelers of microscopic animalcules. The only relief in these warehouse-walls was at small flat wharves specializing in this or that type of cargo, and connected to the world by rays of pounded dirt. On the left or Wapping bank, those streets led into a city that had, dumbfoundingly, been summoned into being during Daniel’s absence. On the right or Southwark bank, the buildings soon dwindled to a mere screen along the water-front, with open country beyond. But Daniel was only allowed to see into it when the boat swam into transitory alignment with a south-going road. Such roads were lined with new buildings for a quarter-mile or so inland, making them look like sword-cuts hacked into the city. And the country beyond was not your English farmsteads (though there were pastures and dairies) but your quasi-industrial landscape of tenter-grounds and tanner yards, the inherently land-hungry manufactures of large flat goods.
