Attention turned to the city itself, as the water broached the tent wall on the east side of Burroughs, and ran in over the coping by Southwest Gate, where they had cut the tent. Soon thereafter it was flooding Princess Park and Canal Park and the Niederdorf, dividing the city in two and then slowly rising up the side boulevards, covering the roofs in the lower part of town.

In the midst of this spectacle one of the big jets appeared in the sky over the plateau, looking much too slow to fly, as big planes low to the ground always do. It had taken off southward, so for the spectators on the ground it grew larger and larger without ever seeming to gain speed, until the low rumble of its eight engines reached them, and it plowed overhead with the slow impossible awkwardness of a bumblebee. As it lumbered off to the west the next one appeared over the spaceport, and headed past the water-floored city and over them, off to the west. And so it went for all five planes, each one looking as unaerodynamic as the last, until the last one had trolled past them and disappeared over the western horizon.

Now they began to walk in earnest. The fastest walkers took off, making no attempt to stay back with the slower ones; it was important to begin to train people away from Libya Station as soon as possible, and this was understood by all. Trains were on their way to Libya from all over, but Libya Station was small and had only a few sidings, so the choreography of the evacuation was going to be complex.

It was now five in the afternoon, the sun low over the rise of Syrtis, the temperature plummeting past zero, on its way far down. As the faster walkers, mostly natives and the latest immigrants, pressed on ahead, the crowd became a long column. The people in rovers reported that it was several kilometers long now, and getting longer all the time. These rovers drove up and down the line, picking people up and sometimes letting others out. All available walkers and helmets were being used. Coyote had appeared on the scene, driving up from the direction of the dike, and seeing his boulder car, Nadia instantly suspected he was behind the broaching of the dike; but after greeting her cheerily over the wrist, and asking how things were going, he drove back toward the city. “Get South Fossa to send a dirigible over the city,” he suggested, “in case anyone was left behind, and is up on the mesa tops. There must be some people in there who slept through the day, and when they wake up they are in for one very big surprise.”

He laughed wildly, but it was a good point, and Art made the call.
