On the evening of my first communication with Mars, Zarlah was testing this instrument on Almos' mind, when, to her great astonishment, she came into thought communication with Earth. As this was the first trial of the instrument, Almos himself was unaware of the success that had crowned Zarlah's invention, though he had taken much interest in it, and had on several occasions given his advice during its construction. Although this instrument was only capable of transmitting and receiving thought-waves over a few miles, it was evident that through the medium of Almos' mind, which was in communication with mine, the thought-waves were conveyed to Earth by the super-radium current. Zarlah had thus learned of my proposed visit to Mars, but had not known when the attempt was to be made, until, seeing Almos in evident distress at the recital of the lumaharp, she had feared that the attempt had proved disastrous. When, however, I evinced my astonishment at seeing her, she knew instantly that before her stood the personality of the man from distant Earth, who had been projected to her in mental pictures, and who was called Harold Lonsdale. When I spoke to her of my love, she realized that her image had also been projected to my mind, and, as she listened to my impassioned words, she recognized in them the thoughts of love that had accompanied the projection of my image. Indeed, my every thought of Zarlah, during wave contact, had been projected to her through the medium of this remarkable instrument. With a keen desire to see and examine the mechanism, by which thoughts could be transferred over millions of miles, I said: "But where is this wonderful instrument of which you speak, Zarlah?" We had reached the lake, and now stood on the bank overlooking its glistening surface. A tremor ran through her slight form as she drew closer to me, and said imploringly: "You must not ask to see it! Oh, Harold! Do you not realize the grief this instrument has brought into our lives? Have you partaken of the sweetness so deeply, that you fail to perceive the bitterness that lies beneath? You can be but a beloved memory to me--the memory of a lover millions of miles away--but we are separated by that which is far greater than distance!" Her voice died away in a sob, and, as I drew her gently toward me, she wept bitterly. Thus had I of Earth brought tears into a world that had not known sorrow for hundreds of years.
