 What planet are the mysterious signals coming from?
So far as it has been possible to test the direction of the source of these waves, it appears that the direction has a twenty-four hour cycle, thus indicating that the origin of these waves is some point outside the earth. The university authorities will express no opinion as to whether or not these messages come from Mars. Myles, alone of all the radio engineers of my acquaintance, was competent to surmount these difficulties, and thus enable the Cambridge savants to receive with clearness the message from another planet. 6 Twelve months ago he would have been available, for he was then quietly visiting at my farm, after five earth-years spent on the planet Venus, where, by the aid of radio, he had led the Cupians to victory over their oppressors, a human-brained race of gigantic black ants. During the weeks that followed there was recorded Myles’s own account of the amazing adventures on the planet Venus (or Poros, as its own inhabitants call it,) which befell him upon his return there after his brief visit to the earth. 9 During his stay on my farm, Cabot had built the matter-transmitting apparatus, with which he had shot himself off into space on that October night on which he had received the message from the skies: “S O S, Lilla.” As he stood thus expectant, Myles realized that his present position and condition, the surrounding scenery, and the advance of the ant-men were exactly, item for item, like the opening events of his first arrival on the planet Poros. He was home once more, back again upon the planet which held all that was dear to him in two worlds. How eager he was to reach her side, and save her from that peril, whatever it was, which had caused her to flash that “S O S” a hundred million miles across the solar system from Poros to the earth. He wondered what could have happened in Cupia since his departure, only a few sangths ago. These and a hundred other similar questions flooded in upon the earth-man, as the Formian airship carried him, a captive, through the skies. What uninhabited portion of Cupia could this be, over which they were now passing? Apparently a few survivors of the accursed race of Formians were consolidating their position and attempting to build up a new empire in some out-of-the-way portion of the continent.
