The rolling thunder closed in upon them with a final rush that brought it so near that their very bodies seemed to vibrate in harmony with that mighty note of shuddering bass. Then with startling abruptness the green net came. Out from the walls and down from the roof spurted scores of quivering ribbons of blinding green flame. Swiftly the radiant tendrils rushed in upon the shrinking three from every side, while the infra-bass thundered in mighty crescendo. Blake instinctively swept Helen close within the shelter of his arms in an effort to protect her with his own body against the searing menace of those onrushing green flames. The next moment the fiery ribbons were upon them, lashing about their bodies, crossing and crisscrossing in the air above and around them in a great tangled web of interlacing lines of flame that filled the entire platform. * * * * * With a shock of relief Blake found that there was no heat in those strange flames, but his relief was short-lived as the next second brought him realization of the real menace of the radiant ribbons. There was a solidity and strength in those glowing streamers that held them as helplessly captive as though they were gripped in ribbons of steel. Dazed and helpless, the three struggled for a moment in the meshes of the weird net of flame like fish caught in the strands of some giant cosmic seine. The trembling thunder of infra-bass abruptly changed to a thin whining note so high in pitch that it seemed the nearly soundless ghost of a metallic scream. With the change in sound Blake became aware of a new and astounding change in his surroundings. The walls and roof of the station seemed closing in upon him as though he were growing in size at an incredible rate. The next moment he shot through the roof, hurtling on and upward with the velocity of a rocket. The sensation was one that his reeling brain could not even grasp. His body seemed to be inside every stone, iron bar, and lump of earth, yet at the same time every exterior object seemed _within_ his body. It was an eery chaos of a dozen different dimensions blending to form a Space in which there was no known dimension. As they flashed on out to the surface Blake had one hazy glimpse of Manhattan's glowing lights spread all about them. Then the speed of their progress leaped into a new and terrible acceleration that blotted out every tangible sensation from Blake's brain. Time and Space alike seemed to vanish as their hurtling flight sent them rocketing on for distances inconceivably vast through a bleak and appalling Nothingness, where neither sight nor sound existed. Then abruptly the speed of their flight seemed to be lessening. Sensation returned to Blake. He again heard the thin high-pitched metallic wail, now swiftly deepening to the familiar growl of rolling bass. He again noted the presence of the glowing green ribbons of the net that still encircled them.
