They were rushing then toward the looming cone of the Martian Master. As they flashed past it Randall saw Lanier's face working, knew the desire that tore at him even as at himself to burst inside and ascertain whether or not Milton still lived in the laboratories from which they had fled. But they were past it, faces white and grim, were rushing on through the Martian city at reckless speed toward the other mighty cone. * * * * * It seemed that all in the great city were heading toward the same goal, streams of crocodilian Martians and masses of shining centipede-machines filling the streets as they moved toward it. As they came closer to the mighty structure, hearts pounding, they saw that around it surged a mighty mass of Martians and machines. The hordes waiting to be released through the matter-transmitter inside upon the unsuspecting earth! "Try to get the machine inside!" Lanier whispered tensely. "If we can smash that transmitter yet...." Randall nodded grimly. "Keep ready at the ray-tubes," he told the other. As unobtrusively as possible he sent their long mechanism worming forward through the vast throng of machines and Martians, toward the great cone's door. Crouching low, the hands of their watches closing fast toward the twelfth figure, they edged forward in the long machine. At last they were moving through the mighty door, into the cone's interior. They moved slowly on through the mass of machines and crocodile forms inside, then halted. For at the great crowd's center was a clear circle hundreds of feet across, and as Randall gazed across it his heart seemed to leap once and then stop. At the center of that clear circle rose the two cubical metal chambers of the matter-transmitter and receiver. The transmitting chamber, they saw, was flooded with humming force, with white light pouring from its inner walls. It was already in operation, and the masses of Martians in the great cone were only waiting for the moment to sound when the receiver on earth would be operating also. Then they would pour into the chamber to be flashed in masses across the gulf to earth! The eyes of all in the cone seemed turned toward an erect dial-mechanism beside the chambers which was clocklike in appearance, and that would mark the moment when the first Martian could enter the transmitting-chamber and flash out. * * * * * A little distance from the two metal chambers stood a low dais on which there sat the hideous triple-bodied form of the Martian Master. Around him were the massed members of his council, waiting like him for the start of their age-planned invasion of earth. And beside the dais was a figure between two crocodilian guards at sight of whom Randall forgot all else. "Milton! My God, Lanier, it's Milton!" "Milton! They've brought him here to torture or kill him if they find he's lied about the moment they could flash to earth!"
