"Not that," Hugh told him, "Harry simply turned the petcocks, let our gasoline run into the sand." "Good Lord! Was he crazy?" "That's exactly what he was," Hugh declared. "Batty as a bedbug. Touch of space madness. I felt sorry for him. He cowered like a mad animal, beaten by the sense of loneliness and space. He was afraid of shadows. He got so he didn't act like a man. I was glad for him when he died." "But even a crazy man would want to get back to Earth!" protested Scott. "It wasn't Harry," Hugh explained. "It was the Martians, I am sure. Whatever or wherever they are, they probably have intelligences greater than ours. It would be no feat for them, perhaps, to gain control of the brain of a demented man. They might not be able to dominate us, but a man whose thought processes were all tangled up by space madness would be an easy mark for them. They could make him do and think whatever they wanted him to think or do. It wasn't Harry who opened those petcocks, Scott. It was the Martians." He leaned against the pitted side of the ship and stared up at the massive building. "I was plenty sore at him when I caught him at it," he said. "I gave him one hell of a beating. I've always been sorry for that." "What finally happened to him?" asked Scott. "He ran out of the airlock without his suit," Hugh explained. "It took me half an hour to run him down and bring him back. He took pneumonia. You have to be careful here. Exposure to the Martian atmosphere plays hell with a man's lung tissues. You can breathe it all right ... might even be able to live in it for a few hours, but it's deadly just the same." "Well, it's all over now," declared Scott. "We'll get my ship squared around and we'll blast off for Earth. We made it here and we can make it back. And you'll be the first man who ever set his foot on Mars." Hugh grinned. "That will be something, won't it, Scott? But somehow I'm not satisfied. I haven't accomplished a thing. I haven't even found the Martians. I know they're here. An intelligance that's at least capable of thinking along parallel lines with us although its thought processes may not be parallel with ours." "We'll talk it over later," said Scott. "After we get a cup of coffee into you. I bet you haven't had one in
