 What shocked Myles the most when he woke up on the beach?
I exclaimed, as my eye fell on the following item: SIGNALS FROM MARS FAIL TO REACH HARVARD Cambridge, Massachusetts, Wednesday. 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. While at my farm Cabot had rigged up a huge radio set and a matter-transmitting apparatus, with which he had (presumably) shot himself back to Poros on the night of the big October storm which had wrecked his installation. 7 It was my friend of the Harvard math faculty, the man who had analyzed the measurements of the streamline projectile in which Myles Cabot had shot to earth the account of the first part of his adventures on Venus. Some further adventures Myles had told me in person during his stay on my farm. Kellogg’s reply gave my sluggish mind the second jolt which it had received that day. As a result of our conference, a small committee of engineers returned with me to Edgartown that evening for the purpose of trying to repair the wrecked radio set which Myles Cabot had left on my farm. They utterly failed to comprehend the matter-transmitting apparatus, and so—after the fallen tower had been reerected and the rubbish cleared away—they had devoted their attention to the restoration of the conversational part of the set. And not with Mars after all these years of scientific speculations. But what meant more to me was that I was again in touch with my classmate Myles Standish Cabot, the radio man. The next day a party of prominent scientists, accompanied by a telegrapher and two stenographers, arrived at my farm. 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.
 Enemies arrived that he believed to be dead.
 Enemies arrived that he believed to be dead.  He was on Venus instead of Mars.  He realized Prince Yuri was alive.  He knew he'd been dreaming.
