I remember the occasion with extreme vividness. The water was boiling, and everything was prepared, and the sound of his “zuzzoo” had brought me out upon the verandah. His active little figure was black against the autumnal sunset, and to the right the chimneys of his house just rose above a gloriously tinted group of trees. Remoter rose the Wealden Hills, faint and blue, while to the left the hazy marsh spread out spacious and serene. And then —
The chimneys jerked heavenward, smashing into a string of bricks as they rose, and the roof and a miscellany of furniture followed. Then overtaking them came a huge white flame. The trees about the building swayed and whirled and tore themselves to pieces, that sprang towards the flare. My ears were smitten with a clap of thunder that left me deaf on one side for life, and all about me windows smashed, unheeded.
I took three steps from the verandah towards Cavor’s house, and even as I did so came the wind.
Instantly my coat tails were over my head, and I was progressing in great leaps and bounds, and quite against my will, towards him. In the same moment the discoverer was seized, whirled about, and flew through the screaming air. I saw one of my chimney pots hit the ground within six yards of me, leap a score of feet, and so hurry in great strides towards the focus of the disturbance. Cavor, kicking and flapping, came down again, rolled over and over on the ground for a space, struggled up and was lifted and borne forward at an enormous velocity, vanishing at last among the labouring, lashing trees that writhed about his house.
A mass of smoke and ashes, and a square of bluish shining substance rushed up towards the zenith. A large fragment of fencing came sailing past me, dropped edgeways, hit the ground and fell flat, and then the worst was over. The aerial commotion fell swiftly until it was a mere strong gale, and I became once more aware that I had breath and feet. By leaning back against the wind I managed to stop, and could collect such wits as still remained to me.
In that instant the whole face of the world had changed. The tranquil sunset had vanished, the sky was dark with scurrying clouds, everything was flattened and swaying with the gale. I glanced back to see if my bungalow was still in a general way standing, then staggered forwards towards the trees amongst which Cavor had vanished, and through whose tall and leaf-denuded branches shone the flames of his burning house.
I entered the copse, dashing from one tree to another and clinging to them, and for a space I sought him in vain. Then amidst a heap of smashed branches and fencing that had banked itself against a portion of his garden wall I perceived something stir. I made a run for this, but before I reached it a brown object separated itself, rose on two muddy legs, and protruded two drooping, bleeding hands. Some tattered ends of garment fluttered out from its middle portion and streamed before the wind.
For a moment I did not recognise this earthy lump, and then I saw that it was Cavor, caked in the mud in which he had rolled. He leant forward against the wind, rubbing the dirt from his eyes and mouth.
He extended a muddy lump of hand, and staggered a pace towards me. His face worked with emotion, little lumps of mud kept falling from it. He looked as damaged and pitiful as any living creature I have ever seen, and his remark therefore amazed me exceedingly.
“Gratulate me,” he gasped; “gratulate me!”
“Congratulate you!” said I. “Good heavens! What for?”
“I’ve done it.”
“You have. What on earth caused that explosion?”
A gust of wind blew his words away. I understood him to say that it wasn’t an explosion at all. The wind hurled me into collision with him, and we stood clinging to one another.
“Try and get back — to my bungalow,” I bawled in his ear. He did not hear me, and shouted something about “three martyrs — science,” and also something about “not much good.” At the time he laboured under the impression that his three attendants had perished in the whirlwind. Happily this was incorrect. Directly he had left for my bungalow they had gone off to the publichouse in Lympne to discuss the question of the furnaces over some trivial refreshment.
I repeated my suggestion of getting back to my bungalow, and this time he understood. We clung arm-in-arm and started, and managed at last to reach the shelter of as much roof as was left to me. For a space we sat in armchairs and panted. All the windows were broken, and the lighter articles of furniture were in great disorder, but no irrevocable damage was done. Happily the kitchen door had stood the pressure upon it, so that all my crockery and cooking materials had survived. The oil stove was still burning, and I put on the water to boil again for tea. And that prepared, I could turn on Cavor for his explanation.
“Quite correct,” he insisted; “quite correct. I’ve done it, and it’s all right.”
“But,” I protested. “All right! Why, there can’t be a rick standing, or a fence or a thatched roof undamaged for twenty miles round….”
“It’s all right — really. I didn’t, of course, foresee this little upset. My mind was preoccupied with another problem, and I’m apt to disregard these practical side issues. But it’s all right — ”
“My dear sir,” I cried, “don’t you see you’ve done thousands of pounds’ worth of damage?”
“There, I throw myself on your discretion. I’m not a practical man, of course, but don’t you think they will regard it as a cyclone?”
“But the explosion — ”
“It was not an explosion. It’s perfectly simple. Only, as I say, I’m apt to overlook these little things. Its that zuzzoo business on a larger scale. Inadvertently I made this substance of mine, this Cavorite, in a thin, wide sheet….”
He paused. “You are quite clear that the stuff is opaque to gravitation, that it cuts off things from gravitating towards each other?”
“Yes,” said I. “Yes.”
“Well, so soon as it reached a temperature of 60 degrees Fahrenheit, and the process of its manufacture was complete, the air above it, the portions of roof and ceiling and floor above it ceased to have weight. I suppose you know — everybody knows nowadays — that, as a usual thing, the air has weight, that it presses on everything at the surface of the earth, presses in all directions, with a pressure of fourteen and a half pounds to the square inch?”
“I know that,” said I. “Go on.”
“I know that too,” he remarked. “Only this shows you how useless knowledge is unless you apply it. You see, over our Cavorite this ceased to be the case, the air there ceased to exert any pressure, and the air round it and not over the Cavorite was exerting a pressure of fourteen pounds and a half to the square in upon this suddenly weightless air. Ah! you begin to see! The air all about the Cavorite crushed in upon the air above it with irresistible force. The air above the Cavorite was forced upward violently, the air that rushed in to replace it immediately lost weight, ceased to exert any pressure, followed suit, blew the ceiling through and the roof off….
“You perceive,” he said, “it formed a sort of atmospheric fountain, a kind of chimney in the atmosphere. And if the Cavorite itself hadn’t been loose and so got sucked up the chimney, does it occur to you what would have happened?”
I
