in the darkness, with only the sound of her breathing and the thin protests of the moss under her feet. Sometimes his collar jerked as she changed course to avoid some obstacle. "I have no weight, but I still have mass and therefore inertia," he found himself thinking, and knew he should be afraid instead of indulging in such random observations. He discovered he could turn his head, although the rest of his body remained locked in weightless rigidity, and gradually he became aware of something following them. From the glimpses he caught in the slanting red moonbeams it resembled a lemur. He watched it glide from tree to tree like a flying squirrel, catch the rough bark and scramble upward, glide again. A whistle, overhead, a sound entirely distinct from that of the wind-whipped branches, brought the girl to a sudden stop. She jerked Eldon to a halt in mid-air beside her and pulled him into the deeper shadow beneath a gnarled tree just as a great torpedo-shaped thing passed above the treetops, glistening like freshly spilled blood in the moonglow. Some sort of wingless aircraft. They waited, the girl fearful and alert. The red moon dropped below the horizon and a few stars—they were of a normal color—did little to relieve the blackness. The flying craft returned, invisible this time but still making a devilish whistle that grated on Eldon's nerves like fingernails scraped down a blackboard as it zigzagged slowly back and forth. Then gradually the noise died away in the distance. The girl sighed with relief, made a chirruping sound, and the lemur-thing came skittering down the tree beneath which they were hiding. She spoke to it, and it gave a sailing leap that ended on Eldon's chest. Its handlike paws grasped the fabric of his shirt. He sank a few inches toward the ground, but immediately floated upward again with nightmarish buoyancy. The girl reached to her belt again, and then she was floating in the air beside him. She grasped his collar and they were slanting upward among the branches. The lemur-thing rose confidently, perched on his chest. They moved slowly up to treetop level, where the girl paused for a searching look around. Then she rose above the trees, put on speed, and the hot wind whistled around Eldon's face as she towed him along. It was a dream-scene where time had no meaning. It might have been minutes or hours. The throbbing of his headache diminished, leaving him drowsy.
