And the autopsy, beyond determining that the Martians probably obtained chemicals and oxygen by chewing up the soil, which contained many oxides, was bewildering. Spartan made pictures and microscope slides which could be studied if or when we got back on the earth. All we know was that on Mars, life was a sort of mobile vegetable which wasn't really a vegetable; and it was decidedly poisonous. We didn't know how these creatures reproduced, but Gail expressed the opinion that some of the "arms," all of which seemed to have different uses, might be sex organs and that Martians gave birth to their young by a kind of "budding," which exists among lower forms of life on earth. "Probably every Martian is both male and female," she said, "like some worms." Like the electric eel, they had organs which produced a strong electric current. But their radar equipment--the metallic hump and the black spot on top of it--baffled us all. Nature had done the job compactly and bewilderingly, with cells. "Those teeth look vicious," said Gail. "I wonder if their owners are," said Joel. "They spied on us during the entire trip from earth. They clouded our scope so we couldn't use radar. They chased Drake. That's an indication that they might be vicious." Axel shook his head. "They were just cautious," he said. "We'd have been just as cautious if Martians had come to the earth. And they didn't really seem to be chasing Bill. He was frightened and ran. They saw no reason to fear him, so they followed, possibly trying to establish communication." "Yes," I said. "They tried to imitate our language. Did a pretty good job, too." There had been nothing vicious or hostile in that. "But one thing we can be sure of," said Axel, "is that the next time they see us, they will attack us. We have lost our chance to be friends of the Martians. I'm sure the two who saw Bill had seen sent to spy on us and they must have notified others, by radio, that they had made contact. Now they are missing. Only one conclusion could be drawn. We killed them. And this is an act they'll demand revenge for." "Bah!" said Spartan. "There's nothing to worry about. We've shown them we are the ones to fear. We have strength. These lower forms of life understand strength--they'll leave us alone." "Lower forms of life?" said Axel. "And what makes a creature a higher form? I'd say we're the lower forms on Mars, because we have difficulty living here. We're not successful in this environment. We'd become extinct in a short time if we were transplanted here permanently." Dr. Spartan's face grew dark inside his helmet. His words were spoken in a manner implying threat. "You're forgetting, Ludson," he said, "that I'm the commander here. I'm not to be contradicted or spoken to in the way you've just done. I'll do all the thinking for this group." He rinsed off his gloves with the water from the canal and went into the ship. _Chapter 14_
