Crocodile-men! It was only so that he could think of them in that moment. For they were terribly like great crocodile shapes that had learned in some way to carry themselves erect upon their hinder limbs. The bodies were not covered with skin, but with green bony plates. The limbs, thick and taloned at their paw-ends, seemed greater in size and stronger, the upper two great arms and the lower two the legs upon which each walked, while there was but the suggestion of a tail. But the flat head set on the neckless body was most crocodilian of all, with great fanged, hinged jaws projecting forward, and with dark unwinking eyes set back in bony sockets. Each of the creatures wore on his torso a gleaming garment like a coat of metal scales, with metal belts in which some had shining tubes. They were standing in groups here and there about the mechanisms, the nearest group at a strange big switch-panel not a half-dozen feet from the three men. Milton and Lanier and Randall returned in a tense silence the unwinking stare of the monstrous beings around them. "The Martians!" Lanier's horror-filled exclamation was echoed in the next instant by Randall's. "The Martians! God, Milton! They're not like anything we know--they're reptilian!" * * * * * Milton's hand clutched his shoulder. "Steady, Randall," he muttered. "They're terrible enough, God knows--but remember we must seem just as grotesque to them." The sound of their voices seemed to break the great hall's spell of silence, and they saw the crocodilian Martians before them turning and speaking swiftly to each other in low hissing speech-sounds that were quite unintelligible to the three. Then from the small group nearest them one came forward, until he stood just outside the chamber in which they were. Randall felt dimly the momentousness of the moment, in which beings of earth and Mars were confronting each other for the first time in the solar system's history. The creature before them opened his great jaws and uttered slowly a succession of sounds that for the moment puzzled them, so different were they from the hissing speech of the others, though with the same sibilance of tone. Again the thing repeated the sounds, and this time Milton uttered an exclamation. "He's speaking to us!" he cried. "Trying to speak the English that I taught them in our communication! I caught a word--listen...." As the creature repeated the sounds, Randall and Lanier started to hear also vaguely expressed in that hissing voice familiar words: "You--are Milton and--others from--earth?" Milton spoke very clearly and slowly to the creature: "We are those from earth," he said. "And you are the Martians with whom we have communicated?" "We are those Martians," said the other's hissing voice slowly. "These"--he waved a taloned paw toward those behind him--"have charge of the matter-transmitter and receiver. I am of our ruler's council."
