"Still," Buck's words came slowly, "this is a choice between two evils, rather than between an evil and a good--" "Then let us see how powerful this evil is!" Jil-Lee headed for the corridor leading to the pillar. * * * * * It was late afternoon when they made their way through the swirling mists of the valley under the archway giving on the former site of the outlaw Tatar camp. Travis sighted the long barrel of the weapon at a small bush backed by a boulder, and he pressed the firing button. There was no way of knowing whether the weapon was loaded except to try it. The result of his action was quick--quick and terrifying. There was no sound, no sign of any projectile ... ray-gas ... or whatever might have issued in answer to his finger movement. But the bush--the bush was no more! A black smear made a ragged outline of the extinguished branches and leaves on the rock which had stood behind. The earth might still enclose roots under a thin coating of ash, but the bush was gone! "The breath of Naye'nezyani--powerful beyond belief!" Buck broke their horrified silence first. "In truth evil is here!" Jil-Lee raised his gun--if gun it could be called--aimed at the rock with the bush silhouette plain to see and fired. This time they were able to witness disintegration in progress, the crumble of the stone as if its substance was no more than sand lapped by river water. A pile of blackened rubble remained--nothing more. "To use this on a living thing?" Buck protested, horror basing the doubt in his voice. "We do not use it against living things," Travis promised, "but against the ship of the Reds--to cut that to pieces. This will open the shell of the turtle and let us at its meat." Jil-Lee nodded. "Those are true words. But now I agree with your fears of this place, Travis. This is a devil thing and must not be allowed to fall into the hands of those who--" "Will use it more freely than we plan to?" Buck wanted to know. "We reserve to ourselves that right because we hold our motives higher? To think that way is also a crooked trail. We will use this means because we must, but afterward...." Afterward that warehouse must be closed, the tapes giving the entrance clue destroyed. One part of Travis fought that decision, right though he knew it to be. The towers were the menace he had believed. And what was more discouraging than the risk they now ran, was the belief that the treasure was a poison which could not be destroyed but which might spread from Topaz to Terra.
