Eldred nodded. He had no words to spare just then.
Grimfern's forefinger pressed the polished button, there was a snap and almost immediately a roar and a rush of air that set the aerophane rocking violently. All about them the clouds were spinning, below the foggy envelope was twisted and torn as smoke is blown away from a huge stack by a high wind.
"Look," Hackness yelled. "Look at that!"
The brilliant light of day shone through down into London as from a gigantic skylight.
He pointed downwards. The force of the explosion had literally torn a hole in the dense foggy curtain. The brilliant light of day shone through down into London as from a gigantic skylight.
This is what the amazed inhabitants of central London saw as they rushed out of their houses after what they imagined to be a shock of earthquake. The effect was weird, wonderful, one never to be forgotten. From a radius of half a mile from St. Paul's, London was flooded with brilliant light. People rubbed their eyes, unable to face the sudden and blinding glare. They gasped and thrilled with exultation as a column of fresh sweet air rushed to fill the vacuum. As yet they knew nothing of the cause. That brilliant shaft of light showed strange things. Every pavement was black as ink, the fronts of the houses looked as if they had been daubed over with pitch. The roads were dark with fatty soot. On Ludgate Hill were dozens of vehicles from which the horses had been detached. There were numerous motor cars apparently lacking owners. A pickpocket sat in the gutter with a pile of costly trinkets about him, gems that glittered in the mud. These things had been collected before the fog grew beyond endurance. Now they were about as useful to the thief as an elephant might have been.
At the end of five minutes the curtain fell again. The flying, panic-stricken pickpocket huddled down once more with a frightened curse.
But London was no longer alarmed. A passing glimpse of the aerophane had been seen, and better informed folks knew what was taking place. Presently another explosion followed, tearing the curtain away over Hampstead; for the next two hours the explosions continued at short intervals. There were tremendous outbursts of cheering whenever the relief came.
Presently a little light seemed to be coming. Ever and again it was possible for a man to see his hands before his face. Above the fog banks a wrack of cloud had gathered, the aerophane was coated with a glittering mist. An hour before it had been perfectly fair overhead. Then it began to rain in earnest. The constant explosions had summoned up and brought down the rain as the heavy discharge of artillery used to do in the days of the Boer War.
