sir!" he said. "Attacking an alien race without weighing the outcome would have been an act of criminal folly, charged with great danger to ourselves." Commander Gurney shook his head in angry disagreement. "Just how would you define murder, Langford?" he demanded. "If a highly intelligent buzzsaw came at you would you bare your throat?" Langford ignored the question. "Violence breeds violence, sir," he said, with patient insistence. "Suppose the shoe were on the other foot. Suppose the inhabitants of another planet attacked you without giving you a chance to prove your friendliness?" Langford's eyes held a dogged conviction. "Remember, sir—to issue a warning is an act of forbearance. No reasonable man could mistake a warning for an aggressive act. If their weapons are superior to ours, or they are superior to us in other, truly terrifying ways, they proved their friendliness by warning us. Would you have had me attack their ship without studying that warning?" Gurney's eyes had returned to the statue. He seemed fascinated by the glitter of its folded wings. He had a sudden vision of the metal insect spreading its wings and taking off with a low, horrible droning. Suddenly there was a dull throbbing in the Patrol commander's temples.

"There were two metal insects in that capsule, sir. I'm going to show you exactly what happened to the one I experimented with." Langford's forefinger whipped out as he spoke, striking the little statue sharply on its folded wing membranes. For an instant nothing happened; then, with appalling
