In several places along the equator of New Earth, ground had been cleared and flattened, and reinforced concrete pads laid. These had the same size and shape as Cradle’s undersurface, and were equipped with their own hatches and orifices matching those on Cradle. Cradle could be neatly set down into one of these sockets whenever the Eye happened to be directly overhead. There it might reside for hours or days, taking on or discharging supplies, and otherwise communing with the surroundings. But it never stayed for long, since it had to follow the movements of the Eye, which always had urgent business elsewhere on the ring.
