For a single moment the whole scene seemed as motionless as a set tableau. Then with a wild shout I whirled the great ax high above my head, swung it for an instant in a flashing circle, and then brought it down with the last mad remnant of my force upon the half-severed cable below, a powerful blow that clove through its twisted strands as a knife might cut through cords. There was a flash of light as the cable parted, and then the brilliance of the great cylinder's upper surface had snapped out, and the mighty ray that sprang from it had vanished! The next instant there was utter silence, a thick, terrific silence in which we, and all the nebula-creatures that had crowded up onto the pit's floor, gazed up toward the mighty nebula's fires, far above us. Seconds, minutes, that awful silence reigned, and then I saw the weapons of the nebula-creatures before us dropping from their grasp, saw them rushing wildly about as though in mad, frenzied terror, heard a great cry from Jor Dahat, beside me. "The nebula!" he cried hoarsely, pointing up toward the glowing fires above. "The nebula--_collapsing_!" I looked up, dazedly, saw the vast fires moving now, slowly, majestically, gigantically, moving down toward us, toward the nebula world, the whole vast turning nebula collapsing into the great space at its center with the removal of the ray that had whirled it on, its mighty, crowding fires rushing down upon us. Then I had sunk to the floor, felt the arms of my two friends about me, dimly felt myself dragged across the floor through the crazily rushing hordes of nebula-creatures into our cruiser, felt it lifting up out of the great pit with the plant-man at the controls, as the fires above rushed down upon us. Then there was a thunderous roaring of titanic fires about us, a vast, interminable rushing of colossal currents of flaming gas all around us as we plunged upward through the collapsing nebula. More and more dimly to my ears came that mighty roar of flame as consciousness began to leave me, but at last, through my darkening senses, I felt that it had ceased, that we were humming through space once more. With a last effort I staggered to the window with my two companions, gazed down dazedly toward the terrific ocean of boiling flame that stretched gigantically beneath us, saw that still its fires were drawing together, collapsing, contracting, condensing. Then suddenly up from the collapsing nebula there leapt a single mighty tongue of fire, as from some titanic conflagration, a vast rush of flame that towered up toward the stars, and then dwindled and sank and died. It was the end forever of the world within the nebula. 6
