IT WAS A DULL, ROUTINE LITTLE they skipped several steps in the procedure. Naturally they did not get results at once, nor did they expect to required a fine adjustment. But they were disappointed that they found nothing for several hours as they hovered high over the rotation. Then but one city, if that is its form. Shall we follow the rest of the surface to find another, or concentrate on this? It'll be twelve hours before it's back in our ken if we let it go now." "Let's lock on this one and finish the scan. Then we can do the rest of the world to make sure we've missed nothing," said Stark. had refused to read Positive when turned on the inventor himself, bad blood developed between machine and man. Glaser knew that he had told the machine so heatedly. The machine replied, with such warmth that its relays chattered, that Glaser did not difference , the machine insisted. individual, though this could not be certain) and got very definite assumed an air of importance when it ran these tests. of the shoulders in a man. They called it the "You tell of us will get some sleep. If you find no other spot then we will go down on that one the next time it is in position under us, in about twelve hours." 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 Gregory Gilbert, the executive officer with us." "Howdy," said the priest. He may or may not have been understood, but the two of them smiled at him, so he went on. "Father Briton from Philadelphia," he said, "on detached service. And you, my good man, what is your handle, your monicker, your tag?" "Ha-Adamah," said the man. 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 that you use the English tongue?" "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 to be clothed, as it were, in dignity." "And very little else," said Father Briton, "though that light trick does serve a purpose. But I'm not sure they'd pass in Philadelphia." "Talk to them again," said Stark. "You're the linguist." "That isn't necessary here, Captain. Talk to them yourself." "Are there any other people here?" Stark asked the man. "The two of us. 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 going to prove him wrong? But it does give you a small feeling." "Can we have something to eat?" asked the Captain. "Pick from the trees," said Ha-Adamah, "and then it may be that you will want to sleep on the grass. Being not of human nature (which does not need sleep or rest), it may be that you require respite. But you are free to enjoy the garden and its fruits." "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. "Ask him first. You ask him." "Ha-Adamah, is it allowed to eat the apples?" Father Briton, you are the linguist, but in Hebrew does not Ha-Adamah and Hawwah mean—?" "Of course they do. You know that as well as I." And it was then that Ha-Adamah, the shining man, gave a wild cry: "No, incredible." "It is a little odd. Adam, old man, how long have you been here?" "Forever less six days is the answer that has been given to me. I never did understand the answer, however." "Yes, there is a question that will settle it. Adam, old man, how about "This is hardly the time for clowning," said Stark. "I'm not clowning, Captain. How about it, Adam? I'll give you choice of colors and first move." never played a preternatural mind. Let's just set up the board, Adam, It was a world with everything, and it seemed to have only two inhabitants. They went everywhere except into the big cave. "What is there, Adam?" asked Captain Stark. "The great serpent lives there. I would not disturb him. He has long been cranky because plans he had for us did not materialize. But we persevere, it will come by him." 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 left. And they talked of it as they took off. "A crowd would laugh if told of it," said Stark, "but not many would laugh if they had actually seen the place, or them. I am not a gullible Down in the great cave that Old Serpent, a two-legged one among whose names were "Snake-Oil Sam," spoke to his underlings: "It'll take them fourteen days to get back with the settlers. We'll have time to overhaul the blasters. We haven't had any well-equipped and slaughter and stow before there was another batch to take care of." "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. I was in show business long enough to know never to change a line too soon. I did change Adam and Eve to Ha-Adamah and Hawwah, and the apple to the pomegranate. People aren't becoming any smarter—but they are becoming better researched, and they insist on authenticity. He looked at the three dozen space ships stripped and stacked, and at the rather large pile of bone-meal in one corner. "I know it, Eve. The lion is a very important prop. Maybe one of the "I'm working on it." "And you had better have an armed escort when you return," said Father Briton. "Why in cosmos would we want an armed escort?" zoologically rigged, salted conspicuously with gold and shot through with anachronisms. And moreover he was afraid to play me at checkers." "What?" it was just that he chose not to make our acquaintance personally." "They looked at the priest thoughtfully. "All the time we were there the woman did not speak."
