The possibility of my secret becoming known through an accident (someone breaking into my room or overhearing me talk with Almos) now occurred to me, and, in the fear of my being separated from Zarlah forever, I determined upon another visit to Mars that evening.
I had planned to tell Almos at once of my thoughtless confession of love to Zarlah, but in an effort to justify my great desire to see her again, I now saw several important reasons for postponing this. I had given my promise to Zarlah to be with her the following evening, and it seemed only honorable for me first to fulfil my promise to her. Moreover, under the circumstances, it might be embarrassing for Almos to meet her upon such short notice. When a man takes a step of this kind, he usually has spent some time in consideration beforehand, how much more necessary, then, is time for consideration when this step has been taken for him. I therefore decided to keep my promise to Zarlah and to endeavor to visit Mars again during the next wave contact.
I did not regret having left the note for Almos, however, as I had no means of telling whether the mechanism of the virator had done what was expected of it, or not. Almos' life depended upon the accurate working of this mechanism after I had gone, and I was anxious to learn of his safety. He would also want to learn of my safe arrival before preparing himself for another undertaking of the kind; to see each other was therefore necessary. Almos would undoubtedly have warned me of this, had not the cessation of wave contact prevented him from giving me instructions.
It was late in the afternoon when a feeling of intense hunger reminded me that I had not tasted food for twenty-four hours. I contented myself, however, with a light meal at a neighboring cafe, knowing the danger of eating heavily at this time. To my great surprise, I found that this small amount of food was evidently all my system required. Not only was my hunger appeased, but, while returning to my rooms, I was conscious of a strength and vigor which were entirely new to me, and which I now remembered I had first experienced upon awakening. Could it be that the super-radium current, possessing the wonderful regenerating rays that had brought perpetual life to the people of Mars, was gradually working this change in my body over a distance of millions of miles? Impossible as this seemed there was no other way of accounting for the remarkable change which had taken place in my body.
The intense excitement I experienced at the thought of possessing perpetual life, health, and youth was but momentary, and I reached my laboratory with a full realization of the enormous responsibilities which my discovery was placing upon me. I could no longer keep it secret; each day that I withheld the knowledge of these rays from my fellow beings, hundreds, nay thousands, of lives would be laid to my account. The knowledge had not been given to me that I should guard it selfishly. The hope that, even though I could never call Zarlah my own, I might often spend a few happy hours with her in her Martian paradise was now shattered forever. I must stifle my love or commit a crime against every living soul on Earth; and as I paced my room in agony, with my hands pressed to my temples to ease their throbbing, a great cry of anguish from the multitude in Death's grasp rang through my brain. My heart was torn asunder by two great conflicting emotions, Love and Duty, and in this torture of mind and body I moved restlessly back and forth in my room, until the fading light warned me of the near approach of wave contact with Mars.
There was but one course open to me; I would tell Almos of my experience with the rays, and if he should decide that they were the same as the regenerating rays, possessing all their properties, and that continual life was now within reach of the people on Earth, I would make my discovery public on the morrow. This would be my solemn duty, no matter what sacrifice it involved, and I could not help feeling that this second visit to Mars might be the last.
A hasty examination of my instrument assured me that all was in order, and, turning on the current, I now watched the surface of wires for the glow that would signalize the commencement of wave contact. Should this glow appear without an image of any kind it would have but one meaning—that the mechanism of the virator had failed to do its work the night previous, and that disaster had befallen Almos.
My heart beat fast, therefore, when in a short time a faint glow appeared on the upper portion of my instrument and rapidly spread until it covered the entire surface. As it grew brighter I was obliged to turn away, before I could recognize any image, and, as I stood shielding my eyes from the strong glare, I felt my heart sink within me. But, before I could approach the instrument again, I heard my name called in the clear, ringing tones of Almos' beloved voice.
I reached the instrument with a bound, and there, standing with his hands extended toward me and a smile of greeting on his handsome face, I saw my brave Martian brother.
"My dear Almos, how glad I am to see you are safe!" I cried, tears of joy springing to my eyes at finding that the fears of a moment ago were unfounded.
