Then he saw what was not normal for that or any hour in a terrapin camp. A confusion of bobbing lights among the cars; the shop area in the midst was almost deserted, but against the reddening fires of the forges tiny black figures scurried to and fro like distracted ants. He could almost hear the cries of alarm and exasperation over the discovery that not a functioning engine was left in the whole troop. Torcred turned and caught Relez smiling in his beard. "You did that!" Relez nodded. "Unfortunately, we didn't get the anti-ionization field into operation in time to prevent the buzzards' gas attack. But there won't be any more fighting tonight, unless they do it with knives. It's a bit of luck that none of these people seem to have any notion of portable firearms. No more mechanized warfare, though, as long as that unit is working." He gestured at a thing of massive coils and bus bars and fragile glowing tubes, from which, Torcred perceived now, the humming came. Ladna's blue eyes were wide. "That little device--has stopped all the machines?" "It broadcasts a wave form that affects the molecules of air, of all gases, inhibiting their ionization. So no spark can jump, and motors are stopped when their electric ignition fails. The only machines that can move now, inside its range, are the moles, with their battery-driven electric motors for underground travel--which is lucky for them, or they'd be trapped under the earth. "Everything else--terrapins, trailers, aeros, buzzards, and all the rest--are paralyzed. Our field's range blankets five hundred thousand square miles. Beyond that area, others are responsible for administering the same treatment; it already began a month ago on the coast--" "What are you?" Torcred burst out. "What do you want?" "We three--Dunu, Rhenu, and I--are the Continental Demilitarization Commission for this area. As to what we are trying to do, that will take some explaining--" "I meant," Torcred scowled, dissatisfied, "what is your race?" Relez regarded him strangely. "The same as yours. The race of man." IX They came of peoples which had no history, only legend and tradition. And they learned-- That there was such a thing as history, recorded in books; Relez showed them such a book, which they could not read, because neither of them could understand more than the code markings on mechanical parts. That the storied ancients, whose powers were marvelous and whose end was terrible, had really existed and had left their record in writing.
