life traces on that little moon, but it would be a lively place. So on the body? Naturally they did not get results at once, nor did they expect to it but one city, if that is its form. Shall we follow the rest of the designed simply to locate a source of superior thought. But this might be so varied or so unfamiliar that often both the machine and the difference , the machine insisted. on ninety per cent of the acknowledged superior minds of the Earth. In space it had been a it had read Positive on a two-inch-long worm, only one of them out of billions. For the countless identical worms no trace of anything at all was shown by the test. Finally it signaled the result, the most exasperating result it ever produces: the single orange light. It was the equivalent of the shrug of the shoulders in a man. They called it the "You tell me light." So among the intelligences there was at least one that might be "No. The rest of the world may be dangerous. There must be a reason that thought is in one spot only. If we find no others then we will go down boldly and visit this." So they all, except Steiner, went off to their bunks then: Stark, the Captain Dawn did not come to the moon-town. The Little Probe hovered stationary in the light and the moon-town came up under the dawn. Then the Probe "There's no town," said Steiner. "Not a building. Yet we're on the "Not a building, not two sticks or stones placed together. That looks like an Earth-type sheep there. And that looks like an Earth-lion, I'm almost afraid to say. And those two ... why, they could well be Earth-people. But with a difference. Where is that bright light coming from?" go to meet them at once. Timidity has never been an efficacious tool with us." Well, they were people. And one could only wish that all people were like them. There was a man and a woman, and they were clothed either in very bright garments or in no garments at all, but only in a very bright light. He may or may not have been understood, but the two of them smiled at him, so he went on. but the woman smiled, proving that she was human. "The woman is named Hawwah," said the man. "The sheep is named sheep, the lion is named lion, the horse is named horse and the hoolock is named hoolock." "I understand. It is possible that this could go on and on. How is it "I have only one tongue but it is given to us to be understood by all by the eagle, by the squirrel, by the ass, by the English." "We happen to be bloody Yankees, but we use a borrowed tongue. You wouldn't have a drink on you for a tubful of thirsty travellers, would you?" "The fountain." "Ah—I see." But the crew all drank of the fountain to be sociable. It was water, but water that excelled, cool and with all its original bubbles like the first water ever made. "What do you make of them?" asked Stark. "Human," said Steiner. "It may even be that they are a little more than human. I don't understand that light that surrounds them. And they seem to be clothed, as it were, in dignity." "And very little else," said Father Briton, "though that light trick "Are there any other people here?" Stark asked the man. "The two of us. Man and woman." "But are there any others?" "How would there be any others? What other kind of people could there be than man and woman?" "But is there more than one man or woman?" "How could there be more than one of anything?" The captain was a little puzzled by this, but he went on doggedly: "Ha-Adamah, what do you think that we are? Are we not people?" "You are not anything till I name you. But I will name you and then you can be. You are named Captain. He is named Priest. He is named Engineer. He is named Flunky." "Thanks a lot," said Steiner. "But are we not people?" persisted Captain Stark. "No. We are the people. There are no people but two. How could there be other people?" "And the damnest thing about it," muttered Langweilig, "is, how are you will want to sleep on the grass. Being not of human nature (which does "We will," said Captain Stark. They wandered about the place, but they were uneasy. There were the animals. The lion and lioness were enough to make one cautious, though they offered no harm. The two bears had a puzzling look, as though they wanted either to frolic with you or to mangle you. "If there are only two people here," said Casper Craig, "then it may be that the rest of the world is not dangerous at all. It looked fertile wherever we scanned it, though not so fertile as this central bit. And "Flecked with gold, and possibly with something else," said Stark. "A very promising site." "And everything grows here," added Steiner. "Those are Earth-fruits and whether this is reality. Go ahead and eat one." "I won't be the first to eat one. You eat." "Ask him first. You ask him." "Ha-Adamah, is it allowed to eat the apples?" "Certainly. Eat. It is the finest fruit in the garden." "Well, the analogy breaks down there," said Stark. "I was almost not the idea that it was the apple that was forbidden go back only to a medieval painting?" "It does. The name of the fruit is not mentioned in Genesis. In Hebrew exegesis, however, the pomegranate is usually indicated." "I thought so. Question the man further, Father. This is too that on at least one other unfortunate world it has actually been lost." "Do you consider yourself a knowledgeable man?" "Yes, since I am the only man, and knowledge is natural to man. But I am further blessed. I have a preternatural intellect." Then Stark cut in once more: "There must be some one question you could colors and first move." "No. It would be no contest. I have a preternatural intellect." "No. It would be no contest. I would not like to humble you." They were there for three days. They were delighted with the place. It was a world with everything, and it seemed to have only two inhabitants. They went everywhere except into the big cave. They learned no more of the real nature of the sphere in their time there. Yet all but one of them were convinced of the reality when they Iron, Earth-Type Fauna. Terms. Special Rates for Large Settlement as listed below. Ask for Brochure—Eden Acres Unlimited."

"I think you'd better write me some new lines," said Adam. "I feel like a goof saying those same ones to each bunch." "You are a goof, and therefore perfect for the part.
