Blindly Phobar reverted to a primitive defense in this moment of infinite danger and kicked with all his strength at the squat monster before him. The thing tried to whirl aside, but Phobar's shoe squashed thickly through, and in a disorder of quivering pieces the metal creature fell, and subsided. Knowing at last that the invaders were vulnerable and how they could be killed, Phobar went leaping and stamping on those nearest him. Under foot, they disintegrated into little pulpy lumps of inert metal. In a trice he broke beyond the circle and darted to the control-panel. One quick glance showed him that the roof was now scarcely a half dozen yards above. With fingers that fumbled in haste at tiny levers and dials, he spun several of them--the repulsion-ray full--the attraction-ray full. And when they were set, he picked up the bar he had dropped and smashed the controls so that they were helplessly jammed. He could almost feel the planet catapult through the heavens. The laboratory roof was only a foot over his head. He whirled around, squashed a dozen tiny creeping things, leaped to a disk that was now not more than a few inches broad. Stooping low, balancing himself precariously, he somehow managed to close the tiny switch. A haze of orange light enveloped him, there came a great vertigo and dizziness and pain, he felt himself falling through bottomless spaces.... * * * * * So exhausted that he could scarcely move, Phobar blinked his eyes open to brilliant daylight in the chill of a November Indian summer noon. The sun shone radiant in the heavens; off in the distance he heard a pandemonium of bells and whistles. Wearily he noticed that there were no flame-paths in the sky. Staggering weakly, he made his way to the observatory, mounted the steps with tired limbs, and wobbled to the eyepiece of his telescope which he had left focused on the dark star two hours before. Almost trembling, he peered through it. The dark star was gone. Somewhere far out in the abysses of the universe, a runaway world plunged headlong at ever-mounting speed to uncharted regions under its double acceleration of attraction and repulsion. A sigh of contentment came from his lips as he sank into a heavy and profound sleep. Later he would learn of the readjustments in the solar system, and of the colder climate that came to Earth, and of the vast changes permanently made by the invading planet, and of a blazing new star discovered in Orion that might signify the birth of a sun or the death of a metallic dark world. But these were events to be, and he demanded his immediate reward of a day's dreamless slumber. Transcriber's Note: This etext was produced from _Astounding Stories_ September 1932.
