Venusian instructions as elementary as a blueprint in an Erector set. But simple as the job was, they were obviously impressed by the mechanism they had assembled. It stood impassive until they obeyed the final instruction. "Press Button K ..."

They found button K, and pressed it.

The robot bowed.

"Thank you, gentlemen," it said, in sweet, unmetallic accents. "Now if you will please escort me to the meeting place ..."

It wasn't until three days after the landing that Jerry Bridges saw the Delegate again. Along with a dozen assorted government officials, Army officers, and scientists, he was quartered in a quonset hut in Fort Dix, New Jersey. Then, after seventy-two frustrating hours, he was escorted by Marine guard into New York City. No one told him his destination, and it wasn't until he saw the bright strips of light across the face of the United Nations building that he knew where the meeting was to be held.

But his greatest surprise was yet to come. The vast auditorium which housed the general assembly was filled to its capacity, but there were new faces behind the plaques which designated the member nations. He couldn't believe his eyes at first, but as the meeting got under way, he knew that it was true. The highest echelons of the world's governments were represented, even—Jerry gulped at the realization—Nikita Khrushchev himself. It was a summit meeting such as he had never dreamed possible, a summit meeting without benefit of long foreign minister's debate. And the cause of it all, a placid, highly-polished metal robot, was seated blithely at a desk which bore the designation:

VENUS.

The robot delegate stood up.

"Gentlemen," it said into the microphone, and the great men at the council tables strained to hear the translator's version through their headphones, "Gentlemen, I thank you for your prompt attention. I come as a Delegate from a great neighbor planet, in the interests of peace and progress for all the solar system. I come in the belief that peace is the responsibility of individuals, of nations, and now of worlds, and that each is dependent upon the other. I speak to you now through the electronic instrumentation which has been created for me, and I come to offer your planet not merely a threat, a promise, or an easy solution—but a challenge."

The council room stirred.

"Your earth satellites have been viewed with interest by the astronomers of our world, and we foresee the day when contact between our planets will be commonplace. As for ourselves, we have hitherto had little desire to explore beyond our realm, being far too occupied with internal matters. But our isolation cannot last in the face of your progress, so we believe that we must take part in your affairs.

"Here, then, is our challenge. Continue your struggle of ideas, compete with each other for the minds of men, fight your bloodless battles, if you know no other means to attain progress. But do all this without unleashing the terrible forces of power now at your command. Once unleashed, these forces may or may not destroy all that you have gained. But we, the scientists of Venus, promise you this—that on the very day your conflict deteriorates into heedless violence, we will not stand by and let the ugly contagion spread. On that day, we of Venus will act swiftly, mercilessly, and relentlessly—to destroy your world completely."

Again, the meeting room exploded in a babble of languages.

"The vessel which brought me here came as a messenger of peace. But envision it, men of Earth, as a messenger of war. Unstoppable, inexorable, it may return, bearing a different Delegate from Venus—a Delegate of Death, who speaks not in words, but in the explosion of atoms. Think of thousands of such Delegates, fired from a vantage point far beyond the reach of your retaliation. This is the promise and the challenge that will hang in your night sky from this moment forward. Look at the planet Venus, men of Earth, and see a Goddess
