t the king's order, Jumor hastened from the laboratory. He returned in a few minutes with an apparatus similar to the one which Saranoff had planned to use on Dr. Bird, but larger, and with more dials on the crystal box. At a command from the king, Dr. Bird donned the helmet.
The king manipulated switches and dials. Around Dr. Bird's head glowed a halo of crimson light. Twice an expression of momentary pain passed over his countenance. After half an hour, Astok cut on the power and nodded to Carnes.
"Don't try to hold anything back, Carnesy," said Dr. Bird sharply. "You couldn't if you tried, and the process is very painful, I can assure you."
With the helmet on his head the detective sat for ten minutes while the Selom king went through his brain. A dozen times he shrieked in agony but his moments of suffering were short. The king removed the helmet.
"Your minds agree well," he thought. "Now I will examine the mind of my friend."
The helmet was strapped on Saranoff. Instantly an expression of the utmost anguish crossed his face. Shriek after shriek of agony came from his writhing lips. Relentlessly the king applied more power. The cries of the Russian grew heartrending. Suddenly he grew rigid and slumped forward in his chair. Astok impassively manipulated his instrument. After half an hour, he opened the switch and removed the helmet. Under the ministrations of Jumor the Russian revived. The king sat in secret thought for an hour.
"I have examined the brains of all of you," he announced at length, "and I find hopeless contradictions. Each of you believes thoroughly in his own social order. Both tell me of hopeless misery on the part of a large portion of his people. Both tell of horrible wars and suffering beyond my comprehension. The thoughts of all of you teem with modes of bringing death to your fellow beings. Your entire science his been perverted to the ends of destruction. Nothing of the sort can be realized by the Selom where truth, justice and mercy prevail. Each of you holds that his form of government is better than the other, and will cause less suffering and misery than the others'. None of you hold out hope of happiness for your fellow beings. I do not know which system is less obnoxious. My decision is made. The Selom will not interfere in the affairs of the upper-earth. You may fight out your battles without aid and without interference.
"I will operate on both Ivan Saranoff and Dr. Bird. I will remove from their minds all knowledge of our science and instruments and leave them in the same condition that they were when they entered my realms. Each of you will then be returned to upper-earth, Ivan Saranoff to Russia, Dr. Bird and Mr. Carnes to the United States. The pilots, whom I hold prisoners, will have their mentalities restored and be returned to their homes. The planes we have captured, I will send off into time so that they can never be used for the misery of upper-earth men again. Jumor, you will carry out these orders."
