t was shortly after he had returned to Washington, that the aliens gave the waiting world the reasons for their appearance on Earth. They were, they said, members of a very ancient highly evolved culture called Aztlan. And the Aztlans, long past the need for conquest and expansion, had turned their mighty science to the help of other, less fortunate, races in the galaxy. The aliens were, in a sense, missionaries—one of hundreds of teams travelling the star lanes to bring the benefits of Aztlan culture to less favored worlds. They were, they unblushingly admitted, altruists—interested only in helping others.

It was pure corn, Matson reflected cynically, but the world lapped it up and howled for more. After decades of cold war, lukewarm war, and sporadic outbreaks of violence, that were inevitably building to atomic destruction, men were willing to try anything that would ease the continual burden of strain and worry. To Mankind, the Aztlans' words were as refreshing as a cool breeze of hope in a desert of despair.

And the world got what it wanted.

Quite suddenly the aliens left the Northwest, and accompanied by protective squads of FBI and Secret Service began to cross the nation. Taking widely separated paths they visited cities, towns, and farms, exhibiting the greatest curiosity about the workings of human civilization. And, in turn, they were examined by hordes of hopeful humans. Everywhere they went, they spread their message of good will and hope backed by the incredibly convincing power of their telepathic minds. Behind them, they left peace and hopeful calm; before them, anticipation mounted. It rose to a crescendo in New York where the paths of the star men met.

The Aztlans invaded the United Nations. They spoke to the General Assembly and the Security Council, were interviewed by the secretariat and reporters from a hundred foreign lands. They told their story with such conviction that even the Communist bloc failed to raise an objection, which was as amazing to the majority of the delegates as the fact of the star men themselves. Altruism, it seemed, had no conflict with dialectic materialism. The aliens offered a watered-down variety of their technology to the peoples of Earth with no strings attached, and the governments of Earth accepted with open hands, much as a small boy accepts a cookie from his mother. It was impossible for men to resist the lure of something for nothing, particularly when it was offered by such people as the Aztlans. After all, Matson reflected bitterly, nobody shoots Santa Claus!

From every nation in the world came invitations to the aliens to visit their lands. The star men cheerfully accepted. They moved across Europe, Asia, and Africa—visited South America, Central America, the Middle East and Oceania. No country escaped them. They absorbed languages, learned customs, and spread good will. Everywhere they went relaxation followed in their footsteps, and throughout the world arose a realization of the essential brotherhood of man.

It took nearly three years of continual travelling before the aliens again assembled at UN headquarters to begin the second part of their promised plan—to give their science to Earth. And men waited with calm expectation for the dawn of Golden Age.

Matson's lips twisted. Fools! Blind, stupid fools! Selling their birthright for a mess of pottage! He shifted the rifle across his knees and began filling the magazine with cartridges. He felt an empty loneliness as he closed the action over the filled magazine and turned the safety to "on". There was no comforting knowledge of support and sympathy to sustain him in what he was about to do. There was no real hope that there ever would be. His was a voice crying in the wilderness, a voice that was ignored—as it had been when he visited the President of the United States....

atson entered the White House, presented his appointment card, and was ushered past ice-eyed Secret Service men into the presidential office. It was as close as he had ever been to the Chief Executive, and he stared with polite curiosity across the width of desk which separated them.

"I wanted to see you about the Aztlan business," the President began without preamble. "You were there when their ship landed, and you are also one of the few men in the country who has seen them alone. In addition, your office will probably be handling the bulk of our requests in regard to the offer they made yesterday in the UN. You're in a favorable spot." The President smiled and shrugged. "I wanted to talk with you sooner, but business and routine play the devil with one's desires in this office.

"Now tell me," he continued, "your impression of these people."

"They're an enigma," Matson said flatly. "To tell the truth, I can't figure them out." He ran his fingers through his hair with a worried gesture. "I'm supposed to be a pretty fair physicist, and I've had quite a bit of training in the social sciences, but both the mechanisms and the psychology of these Aztlans are beyond my comprehension. All I can say for sure is that they're as far beyond us as we are beyond the cavemen. In fact, we have so little in common that I can't think of a single reason why they would want to stay here, and the fact that they do only adds to my confusion."

"But you must have learned something," the President said.

"Oh we've managed to collect data," Matson replied. "But there's a lot of difference between data and knowledge."

"I can appreciate that, but I'd still like to know what you think. Your opinion could have some weight."

Matson doubted it. His opinions were contrary to those of the majority. Still, the Chief asked for it—and he might possibly have an open mind. It was a chance worth taking.

"Well, Sir, I suppose you've heard of the so-called "wild talents" some of our own people occasionally possess?"

The President nodded.

"It is my belief," Matson continued, "that the Aztlans possess these to a far greater degree than we do, and that their science is based upon them. They have something which they call psychomathematics, which by definition is the mathematics of the mind, and this seems to be the basis of their physical science. I saw their machines, and I must confess that their purpose baffled me until I realized that they must be mechanisms for amplifying their own natural equipment. We know little or nothing about psi phenomena, so it is no wonder I couldn't figure them out. As a matter of fact we've always treated psi as something that shouldn't be mentioned in polite scientific conversation."

The President grinned. "I always thought you boys had your blind spots."

"We do—but when we're confronted with a fact, we try to find out something about it—that is if the fact hits us hard enough, often enough."

"Well, you've been hit hard and often," the President chuckled, "What did you find out?"

"Facts," Matson said grimly, "just facts. Things that could be determined by observation and measurement. We know that the aliens are telepathic. We also know that they have a form of ESP—or perhaps a recognition of danger would be a better term—and we know its range is somewhat over a third of a mile. We know that they're telekinetic. The lack of visible controls in their ship would tell us that, even if we hadn't seen them move small objects at a distance. We know that they have eidetic memories, and that they can reason on an extremely high level. Other than that we know nothing. We don't even know their physical structure. We've tried X-ray but they're radio-opaque. We've tried using some human sensitives from the Rhine Institute, but they're unable to get anywhere. They
