Raising Water by Fire. There were two from chaps whose names he did not recognize at all, but who had orderly minds—or so he guessed from their handwriting. These two were the only letters he actually bothered to open and read, simply because they were the only ones whose contents were not wholly predictable. As it turned out, both were from men who had come up with inventions for determining longitude, and sought Daniel’s help in bringing their ideas before the Royal Society. Daniel threw them away.
There were no letters from his wife, or from little Godfrey, which was in no way surprising, given the season of the year and the rough weather. Groping to the very bottom of the basket, he scraped his hand on something jagged, and jerked back. He was not too old to die of tetanus. His fingers emerged sooty, rather than bloody. Pulling all the mail out of the basket and then tilting it towards the window he observed several twisted and blackened shreds of wood and of metal in the bottom. The largest bit was a miniature cask, no more than gallon-sized, such as might be used to transport distilled spirits. One end of it was intact—badly damaged to be sure, but still recognizable as having once been a keg. The staves were bound together by an iron band at the end, and spread out, like lines of longitude from the pole, until they reached the equator. But none of them continued very far into the opposite hemisphere. Some were snapped off clean, some bent outwards, some smashed into splintery brooms. That end of the keg, and its metal band, were gone entirely, though they might be accounted for by some of the loose fragments in the bottom of the basket. Other things were in there, too: gears, springs, levers of wrought brass.
Part of Daniel wanted to overturn this basket on a well-illuminated table and piece the device back together. But instead he buried it again under his unread mail. He had spent a fortnight immobilized by melancholy, and tormented by unreasonable fears. Today his humours had gone back into balance. The Daniel Waterhouse who had cowered in that bed for two weeks was a different chap from the one who was standing by the door, dressed and periwigged. But they could easily change places if he dwelled too long on the dark relics in that basket. They had grown cold, waiting for his attention; let them grow colder still.
THE ROYAL SOCIETY’S HEADQUARTERS comprised two separate houses and a tiny courtyard separating them. During the fund-raising effort, some had gone so far as to style it a “compound.” One of the houses was the northern terminus of Crane Court. Above its ground floor it had two addtional full storeys, plus a garret in the roof space. This garret, which was where Daniel had been lodged, had two small dormer windows facing the Crane Court side, which would have afforded a clear view all the way down to Fleet Street, and even to the Thames, had they not been partially blocked by a low parapet-wall that had been added to the front of the house to make it seem a few feet higher than it really was. So from his bed, Daniel’s view had been of a sort of lead-lined ditch formed where the steeply sloping roof plunged down to die in the base of the parapet: a bathing-place for birds when it rained, and a raceway for rodents in all weathers. For a few hours in the afternoon the sun would traverse the rectangle of sky that showed above the parapet, if the weather happened to be clear. If Daniel stood up and approached the window he could see over the lip of the parapet, where moss, soot, and birdshit vied for hegemony, down into Crane Court, and scan the jumble of rooftops all around. A view of the dome of St. Paul’s was denied him unless he opened the window, thrust his head out, and craned it to the left. Then it was startlingly close. Yet it seemed inapproachable because of the wide crevasse of Fleet Ditch, which broke the city in twain half-way between. If he turned one hundred eighty degrees and looked west, he was confronted by a church that was much closer, and infinitely older: the Rolls Chapel, which appeared to be sinking or collapsing into a spacious church-yard just across Fetter Lane. This medieval pile, which had been used
