He gave that gutter as wide a berth as he could, but proceeded up against the direction of its flow to the edge of the goldsmiths' district, whence Threadneedle and Poultry and Lombard and Cornhill sprayed confusingly. He continued up Cornhill to the highest point in the City of London, where Cornhill came together with Leadenhall (which carried on eastwards, but downhill from here) and Fish Street (downhill straight to London Bridge) and Bishopsgate (downhill towards the city wall, and Bedlam, and the plague-pit they'd dug next to it). In the middle of this intersection a stand-pipe sprouted, with one nozzle for each of those streets, and Thames-water rushed from each nozzle to flush the gutters. It was connected to a buried pipe that ran underneath Fish Street to the northern terminus of London Bridge. During Elizabeth's time some clever Dutchmen had built water-wheels there. Even when the men who tended them were dead or run away to the country, these spun powerfully whenever the tide went out and high water accumulated on the upstream side of the bridge. They were connected to pumps that pressurized the Fish Street pipe and (if you lived on this hill) carried away the accumulated waste, or (if you lived elsewhere) brought a twice-daily onslaught of litter, turds, and dead animals.
