He waited until the heavy breathing that shook his body might be controlled, then corrected himself. "No--this is another--a new one--see the towers! And listen--it's a radio station!" The slender frameworks that towered high in air glowed like flame--a warning to the ships whose lights showed now and then far overhead. And, clear and distinct, there came to the listening men the steady, crackling hiss of an uninterrupted signal. Against the lighted building moving figures showed momentarily, and McGuire pulled his friend into the safe concealment of a tangle of growth, while the group of yelling things sped past. "Come on," he told Sykes; "we can't get away--not a chance! Let's have a look at this place, and perhaps--well, I have an idea!" He slipped silently, cautiously on, where a forest of jungle ferns gave promise of safe passage. * * * * * Some warning had been sounded; the occupants of the building were scattered to aid in the man-hunt. Only one was left in the room where two Earth-men peeped in at the door. The figure was seated upon an insulated platform, and his long hands manipulated keys and levers on a table before him. McGuire and Sykes stared amazedly at this broadcasting station whose air was filled with a pandemonium of crashing sound from some distant room, but McGuire was concerned mainly with the motion of a lean, blood-red hand that swung an object like a pointer in free-running sweeps above a dial on the table. And he detected a variation in the din from beyond as the pointer moved swiftly. Here was the control board for those messages he had heard; this was the instrument that varied the sending mechanism to produce the wailing wireless cries that made words in some far-distant ears. McGuire, as he slipped into the room and crept within leaping distance of the grotesque thing so like yet unlike a man, was as silent as the nameless, writhing horror that had seized them in the dark. He sprang, and the two came crashing to the floor. Lean arms came quickly about him to clutch and tear at his face, but the flyer had an arm free, and one blow ended the battle. The man of Venus relaxed to a huddle of purple and yellow cloth from which a ghastly face protruded. McGuire leaped to his feet and sprang to the place where the other had been. "Hold them off as long as you can!" he shouted to Sykes, and his hand closed upon the pointer. Did this station send where he was hoping? Was this the station that had communicated with the ship that had hovered above their flying field in that far-off land? He did not know, but it was a powerful station, and there was a chance-- * * * * * He moved the pointer frantically here and there, swung it to one side and another; then found at last a point on the outside of the strange design beneath his hand where the pointer could rest while the crashing crackle of sound was stilled.
