only in Centurian humanoids, not Earth-norm human beings. Doc had this solemn human by the throat when I caught up with him. "Tonight," Doc was saying in his old voice that was as crackled and important as parchment, "tonight Man will reach the Moon. The golden Moon and the silver ship, symbols of greed. Tonight is the night when this is to happen." Which are arthritic fingers that were clamped on his collar. "No argument. Sure, up we go. But leave me go or, so help me, I'll fetch you one in the you? teeth!" had now. That and the thing he left. absurd, easy lie. "Old events seem recent to him." The human nodded, Adam's apple jerking in the angry neon twilight. "'Memory Jump,' you mean. All my great-grandfathers have it. But Great-great-grandmother Lupos, funny thing, is like a schoolgirl. or the Book of Thoth or the or the Necronomican Martians approaching the corner were sensing at Doc and me. They itself on human beings?" and especially I hated Martian tourists because I especially hated Martians. They were back into time and created them.

They weren't the human race can tell itself how to achieve a state of pure logic, men without food, without sex, without conflict—just as Doc has achieved the inhabited universe, but reason finally prevailed. He had reached a state of pure thought." girl said. "You can't let it fall into the hands of the Martians." Andre did not deny that he wanted it to fall into his hands. I knew I could not let Doc's—Dad's—time travel thing fall into "The North American government "We can always make it over to the mission," I lied. The clerk turned his upper lip as if he were going to spit. "Awright, since we ain't full up. In ad vance." to pieces and stomped on the pieces. Maybe you can't stop the progress of science, but I knew it might be millenniums before Doc's genes and creative environment were recreated and time travel was rediscovered. Maybe we would be ready for it then. I knew we weren't now. the look on my face. "I'll give you a room it because I didn't want the human race to become a thing of pure reason without purpose, kick the habit—perhaps with Miss Casey's help—but I wasn't really confident.

Seven Cryptical Books of Hsan "I'll be seen with you if you really want to eat." It was certainly unfair and probably immoral. But I had no choice tourist . "But they don't exist," I said wearily. I was a caffeine addict. Earth-norm humans sometimes have the addiction to a slight extent, but same, but the need ran as deep. Earth human. I was a man , of course, not an alien like a Martian. Earthmen ran the whole Solar Federation, but I was just as good as an Earthman. With my suntan and short mane, I could pass, couldn't I? That of course .

Whatever it was was getting closer. This was the first time me as I was pulling on my boot...." I was kneeling on the floor of a Victorian living room. I'm quite familiar with Earth history and I recognized the period immediately. Then I realized what I had been trying to get from Doc all these months—time travel. A thin, sickly man was sprawled in the other chair in a rumpled dressing gown. My eyes held to his face, his pinpoint pupils and snowbird. "My clients have occasioned singular methods of entry into these rooms," the thin man remarked, "but never before have they used instantaneous materialization." The heavier man was half choking, half laughing. "I say—I say, I would like to see you explain this, my dear fellow." this unemployed, former professional man who has gone through a serious illness and is suffering a more serious addiction to tell me the place and time from which he comes." The surprise stung. "How did you know?" I asked. He gestured with a pale hand. "To maintain a logical approach, I must reject the supernatural. Your arrival, unless hallucinatory—and despite my voluntary use of one drug and my involuntary experiences recently with another, I must accept the evidence of my senses or retire from my profession—your arrival was then super-normal. I might say super-scientific, of a science not of my or the good doctor's time, clearly. Time travel is a familiar folk legend and I have been reading an article by the entertaining Mr. Wells. Perhaps he will expand it into one of his novels of scientific romance." looked vaguely like an ice-skate. "Interesting. Perhaps if our visitor would tell us something of his age with special reference to the theory and practice of temporal transference, Doctor, we would be better equipped to judge whether we exist." There was no theory or practice of time travel. I told them all I had ever heard theorized from Hindu yoga through Extra-sensory Perception to Relativity and the positron and negatron. "Interesting." He breathed out suffocating black clouds of smoke. "Presume that the people of your time by their 'Extra-sensory Perception' have altered the past to make it as they suppose it to be. The great historical figures are made the larger than life-size that we I had to help Doc. I had to have some coffee. "What do you want?" "Listen, Kevin. Listen carefully to what I am saying. Doc found a method of time travel. It was almost a purely mathematical, topographical way divorced from modern physical sciences. He kept it secret and he wanted to make money with it. He was an idealist—he had his crusades. How can you make money with time travel?" I didn't know whether she was asking me, but I didn't know. All I knew was that I had to help Doc and get some coffee. did not exist ." I looked up finally and saw a Martian in or about the doorway. "Call me Andre," the Martian said. "A common name but foreign. It should serve as a point of reference." I had always wondered how a thing like a Martian could talk. Sometimes I wondered if they really could. "I'll begin as Miss Casey did—by telling you things. Hundreds of people disappeared from North America a few months ago." "They always do," I told him. "They ceased to exist—as human beings—shortly after they received a book from Doc," the Martian said. "Use one of those sneaky Martian weapons again," I warned him, "and I'll kill the girl." Martians were supposed to be against the The Martian weapon staggered me again. I tried to say something. I
