Gleaming fangs--great scaled forms--reaching talons--it was all a wild phantasmagoria of grotesque forms spinning around him as he struck with all the power of his earthly muscles and felt crocodilian forms staggering and going down beneath his frenzied blows. He heard the roar of an automatic close beside him in the melee as Milton remembered at last through the red haze of his fury the weapon he carried, but before either Randall or Lanier could reach their own weapons a new wave of crocodilian forms had poured onto them that by sheer pressing weight held them helpless, to be disarmed. * * * * * Hissing orders sounded, the arms and legs of the three were tightly grasped by great taloned paws, and the masses of Martians about them melted back from the dais. Held each by two great creatures, Milton and Randall and Lanier faced again the triple-bodied Martian Master, who in all that wild moment of struggle appeared not to have changed his position. The big monster's black eyes stared unmovedly down at them. "You Earth-beings seem of lower intelligence even than we thought," his hissing voice informed them. "And those weapons--crude, very crude." Milton, his face set, spoke back: "It may be that you will find human weapons of some power if your hordes reach earth," he said. "But what compared with the power of ours?" the other asked coldly. "And since our scientists even now devise new weapons to annihilate the earth's races, I think they would be glad of three of those races to experiment with now. The one use we can make of you, certainly." The creature turned its bulging head a little towards the guards who held the three men, and uttered a brief hissing order. Instantly the six Martians, grasping the three tightly, marched them across the great hall and through a different door than that by which they had entered. They were taken down a narrow corridor that turned sharply twice as they went on. Randall saw that it was lit by squares inset in the walls that glowed with crimson light. It came to him as they marched on that night must be upon the Martian city without, since the sun had been sinking when they had crossed it in the centipede-machine. * * * * * Through what seemed an ante-room they were taken, and then into a long hall instantly recognizable as a laboratory. There were many glowing squares illuminating it, and narrow windows high in the wall gave them a glimpse of the city outside, a pattern of crimson lights. Long metal tables and racks filled the big room's farther end, while along the walls were ranged shining mechanisms of unfamiliar and grotesque appearance. Fully a score of the crocodilian Martians were busy in the room, some intent on their work at the racks and tables, others operating some of the strange machines.
