Feliz opened a shed. Several hoppers stood inside, vaguely resembling wheelless two-seater motorcycles, propelled by antigravity and capable of leaping across several thousand years. (They and their present riders had been transported hither in heavy-duty shuttles.) Hers was loaded with recording gear. He had failed to convince her it was overburdened and knew she’d never forgive him if he finked on her. His invitation to Everard—the ranking officer in hand, though here-now simply on vacation—to join them today had been made in a vague hope that the latter would see that load and order her to let her assistant carry part of it.

She sprang to the saddle. “Come on!” she said. “The morning’s getting old.”

He mounted his vehicle and touched controls. Both glided outside and aloft. At eagle height, they leveled off and bore south, where the River Ocean poured into the Middle of the World.

Banks of upflung mist always edged that horizon, argent smoking off into azure. As one drew near afoot, they loomed topplingly overhead. Further on, the universe swirled gray, shaken by the roar, bitter on human lips, while water flowed off rock and gouged through mud. So thick was the cold salt fog that it was unsafe to breathe for more than a few minutes.

From well above, the sight was yet more awesome. There one could see the end of a geological epoch. For a million and a half years the Mediterranean basin had lain a desert. Now the Gates of Hercules stood open and the Atlantic was coming through.

The wind of his passage around him, Nomura peered west across unrestful, many-hued and intricately foam-streaked immensity. He could see the currents run, sucked toward the new-made gap between Europe and Africa. There they clashed together and recoiled, a white and green chaos whose violence toned from earth to heaven and back, crumbled cliffs, overwhelmed valleys, blanketed the shore in spume for miles inland. From them came a stream, snow-colored in its fury, with flashes of livid emerald, to stand in an eight-mile wall between the continents and bellow. Spray roiled aloft, dimming the torrent after torrent, wherein the sea crashed onward.
