A barge from the ark had been towed into the open water between it and the shore, and anchored. The sounds coming from it spoke of complex mechanical internals. After a few minutes it began to rumble and hum, and a fountain of glittering flynk chain, an upside-down U, grew out of its top and began to extend skyward as its velocity built and its sound sharpened into a steady keening note. Within a few minutes the aitrain had elevated to a height of perhaps a hundred meters and begun to give off a soft light, filling the cove and the beach with enough illumination for people to move about easily and read documents. Kathree could now read the name of the ark, blazoned on its fuselage near the nose: Darwin . It must have been sent out from a big TerReForm base—most likely Haida, which served the northern Pacific coast.
