water almost half a mile in diameter. A lane of red plastic buoys marked a channel towards an opening on the far side. The cutter had a draught of little more than a foot, and as they moved along through the flat water, the sun slanting down behind them opening up the submerged depths, they could see the clear outlines of five- and six-storey buildings looming like giant ghosts, here and there a moss-covered roof breaking the surface as the swell rolled past it.
Sixty feet below the cutter a straight grey promenade stretched away between the buildings, the remains of some former thoroughfare, the rusting humped shells of cars still standing by the curb. Many of the lagoons in the centre of the city were surrounded by an intact ring of buildings, and consequently little silt had entered them. Free of vegetation, apart from a few drifting clumps of Sargasso weed, the streets and shops had been preserved almost intact, like a reflection in a lake that has somehow lost its original.
The bulk of the city had long since vanished, and only the steel-supported buildings of the central commercial and financial areas had survived the encroaching flood waters. The brick houses and single-storey factories of the suburbs had disappeared completely below the drifting tides of silt. Where these broke surface giant forests reared up into the burning dull-green sky, smothering the former wheatfields of temperate Europe and North America. Impenetrable Matto Grossos sometimes three hundred feet high, they were a nightmare world of competing organic forms returning rapidly to their Paleozoic past, and the only avenues of transit for the United Nations military units were through the lagoon systems that had superimposed themselves on the former cities. But even these were now being clogged with silt and then submerged.
Kerans could remember the unending succession of green twilights that had settled behind them as he and Riggs moved slowly northward across Europe, leaving one city after another, the miasmic vegetation swamping the narrow canals and crowding from rooftop to rooftop.
Now they were to abandon yet another city. Despite the massive construction of the main commercial buildings, it consisted of little more than three principal lagoons, surrounded by a nexus of small lakes fifty yards in diameter and a network of narrow creeks and inlets which wound off, roughly following the original street-plan of the city, into the outlying jungle. Here and there they vanished altogether or expanded into the steaming sheets of open water that were the residues of the former oceans. In turn these gave way to the archipelagoes that coalesced to form the solid jungles of the southern massif.
The military base set up by Riggs and his platoon, which harboured the biological testing station, was in the most southerly of the three lagoons, sheltered by a number of the tallest buildings of the city, thirty-storey blocks in what had once been the down-town financial sector.
As they crossed the lagoon the yellow-striped drum of the floating base was on its sun-ward side, almost obscured in the reflected light, the rotating blades of the helicopter on its roof throwing brilliant lances across the smaller white-painted hull of the biological testing water at them. Two hundred yards down shore was the smaller white-pointed hull of the biological testing station, moored against a broad hump-backed building which had formerly been a concert hall.
Kerans gazed up at the rectangular cliffs, enough of the windows intact to remind him of the illustrations of sun-dazzled promenades at Nice, Rio and Miami he had read about as a child in the encyclopaedias at Camp Byrd. Curiously, though, despite the potent magic of the lagoon worlds and the drowned cities, he had never felt any interest in their contents, and never bothered to identify which of the cities he was stationed in.
