"And now occurs the most wonderful of all. When everything is in readiness for the spirit to enter the body again, a strong flow of super-radium is sent through the top globe from an instrument attached. Passing through the small chamber and down the narrow passage, it reaches the body, and immediately changes to a return flow. This current is but momentary; the patient is seen to move, and the body is once more quickened by the life spark. The flow of super-radium has conveyed the spirit of the patient from the small chamber above and released it in the body as it returned, in exactly the same manner as it does with light-waves or sound-waves." "Marvelous!" I gasped, though my mind could only slowly comprehend this almost miraculous achievement. With such vast scientific resources nothing seemed impossible to Martians. Almos had stopped abruptly. A change came over him. His face paled and his lips set in a hard, determined expression. Instantly I felt my every faculty strain to the utmost, in response to the new character of this remarkable being. Speaking slowly and deliberately, his keen eyes holding mine fascinated by a strange fire that seemed kindled within them, he said: "A few words more and we have reached that point at which death may await the inhabitant of Earth who would proceed farther. A death that no scientific knowledge can avert. I have tried to school your mind, to the end that you may fully understand the nature of a desperate undertaking, never before attempted by any human being, which, if you wish to attempt, you must risk alone. "Impelled by a motive that I cannot now explain, I have spanned the millions of miles of universe lying between us by a bridge of theories, which, should they prove realities, would enable you to see and live in another world. Should they prove untenable, however, no power on Earth or Mars can save you; in five hours all would be over. You must consider the possible consequences ere it be too late." "Never!" I cried. "My dear Almos, I am too vitally interested; I have proceeded too far now to hesitate at any step toward such a goal. Explain your theories to me, and I will test them, even if it costs me my life, for Mars holds that which is dearer to me than life on Earth ever can be." "Well, my brave fellow," said Almos, his voice softening, "you must follow me closely in all I tell you, and remember every word I say, for to-morrow I can be of no assistance to you. Alone you must undertake the journey." I was glad Almos had not questioned me regarding the import of what I had said in the enthusiasm of the moment, for I could not help feeling now that I had acted unjustly in not confiding in him, at once, the facts regarding the mental image of the beautiful young girl whom I fully believed existed on Mars, and whose destiny, I was certain, was inextricably bound with mine. I now decided to do so on the first opportunity.
