iety and fear in their faces. The throbbing had something to do with the lights. He too looked up.
At first it seemed to him a thing that affected the lights simply, an isolated phenomenon having no bearing on the things below. Each huge globe of blinding whiteness was as it were clutched, compressed in a systole that was followed by a transitory diastole, and again a systole like a tightening grip, darkness, light, darkness, in rapid alternation.
Graham became aware that this strange behaviour of the lights had to do with the people below. The appearance of the houses and ways, the appearance of the packed masses changed, became a confusion of vivid lights and leaping shadows. He saw a multitude of shadows had sprung into aggressive existence, seemed rushing up, broadening, widening, growing with steady swiftness—to leap suddenly back and return reinforced. The song and the tramping had ceased. The unanimous march, he discovered, was arrested, there were eddies, a flow sideways, shouts of "The lights!" Voices were crying together one thing. "The lights! The lights!" He looked down. In this dancing death of the lights the area of the street had suddenly become a monstrous struggle. The huge white globes became purple-white, purple with a reddish glow, flickered, flickered faster and faster, fluttered between light and extinction, ceased to flicker and became mere fading specks of glowing red in a vast obscurity. In ten seconds the extinction was accomplished, and there was only this roaring darkness, a black monstrosity that had suddenly swallowed up those glittering myriads of men.
