* * * * * "Gentlemen," said the President of the Intersolar Council. "There is very little to say. There can be no denying the fact that we have exhausted our efforts at finding a satisfactory solution. "The contents of this book of reports represents the greatest concentration of expert reasoning perhaps ever applied to a single problem. "But alas, the problem remains--unsolved." He paused to glance at his wristwatch. "The aliens return in an hour. As you very well know there is one action that remains for us. It is one we have held to this hour. It is one that has always been present and one that we have been constantly urged to use. "Force, gentlemen. It is not insignificant. It lies at our command. It represents the technology of the Intersolar alliance. I will entertain a motion to use it." There were no nay votes. * * * * * The alien arrived on schedule. The ship grew from a tiny bright speck in the sky to full size. It settled to a graceful landing as before on the strip and silently moved into the revetment. Again it spoke in the voice of the frog, but the tone was, if anything, less human this time. "Earthmen, we have come for your solution." At that instant a hundred gun crews stiffened and waited for a signal behind their carefully camouflaged blast plates and inside dummy buildings.... Harrison was running. The Administration building was empty. His footsteps echoed through the long, silent halls. He headed for an emergency exit that led directly to the blast tunnel. All doors were locked. The only way was over the wall. He paused and tossed the awkward, heavy object over the ten-foot wall. Then, backing toward the building, he ran and jumped for a hold onto the wall's edge. He failed by several inches to reach it. "Earthmen, we have come for your solution." He ran at the wall once more. This time he caught a fair hold with one hand. Digging at the rough concrete with his feet he was able to secure the hold and begin pulling his body upward. Quickly he was over the wall and onto the apron, a hundred yards from the shining metal ship. "Wait!" he shouted. "Wait, for God's sake!" Picking up the object he had tossed over the wall, he raised it above his head and ran toward the alien ship. "Wait! Here is the solution," he gasped. Somehow the command to fire was not given. There was a long moment of complete silence on the field. Nothing moved. Then the voice of the frog boomed from the alien ship. "The solution appears to be correct." * * * * * The alien left three days later. Regular communications would begin within the week. Future meetings would work out technical difficulties. Preliminary trade agreements, adequately safeguarded, were drafted and transmitted to the ship. The Races of Man and the Races of Wan were in harmony. * * * * *
