Martian civilization had developed in a quite different direction from that of Earth. It had developed no important knowledge of the physical sciences, no technology. But it had developed social sciences to the point where there had not been a single crime, let alone a war, on Mars for fifty thousand years. And it had developed fully the parapsychological sciences of the mind, which Earth was just beginning to discover. Mars could teach Earth much. How to avoid crime and war to begin with. Beyond those simple things lay telepathy, telekinesis, empathy.... And Earth would, Mars hoped, teach them something even more valuable to Mars: how, by science and technology--which it was too late for Mars to develop now, even if they had the type of minds which would enable them to develop these things--to restore and rehabilitate a dying planet, so that an otherwise dying race might live and multiply again. Each planet would gain greatly, and neither would lose. And tonight was the night when Earth would make its first sighting shot. Its next shot, a rocket containing Earthmen, or at least an Earthman, would be at the next opposition, two Earth years, or roughly four Martian years, hence. The Martians knew this, because their teams of telepaths were able to catch at least some of the thoughts of Earthmen, enough to know their plans. Unfortunately, at that distance, the connection was one-way. Mars could not ask Earth to hurry its program. Or tell Earth scientists the facts about Mars' composition and atmosphere which would have made this preliminary shot unnecessary. Tonight Ry, the leader (as nearly as the Martian word can be translated), and Khee, his administrative assistant and closest friend, sat and meditated together until the time was near. Then they drank a toast to the future--in a beverage based on menthol, which had the same effect on Martians as alcohol on Earthmen--and climbed to the roof of the building in which they had been sitting. They watched toward the north, where the rocket should land. The stars shone brilliantly and unwinkingly through the atmosphere. In Observatory No. 1 on Earth's moon, Rog Everett, his eye at the eyepiece of the spotter scope, said triumphantly, "Thar she blew, Willie. And now, as soon as the films are developed, we'll know the score on that old planet Mars." He straightened up--there'd be no more to see now--and he and Willie Sanger shook hands solemnly. It was an historical occasion. "Hope it didn't kill anybody. Any Martians, that is. Rog, did it hit dead center in Syrtis Major?" "Near as matters. I'd say it was maybe a thousand miles off, to the south. And that's damn close on a fifty-million-mile shot. Willie, do you really think there are any Martians?" Willie thought a second and then said, "No." He was right. --FREDRIC BROWN [Illustration]
