researches of a scientific nature, and that he possessed a private laboratory, although none of us had ever entered it. Occasionally he would speak of some new advance of science, throwing a flood of light by his clear expositions upon things of which we should otherwise have remained profoundly ignorant. His imagination flashed like lightning over the subject of his talk, revealing it at the most unexpected angles, and often he roused us to real enthusiasm for things the very names of which we almost forgot amidst the next day's occupations.
There was one subject on which he was particularly eloquent—radioactivity; that most strange property of matter whose discovery had been the crowning glory of science in the closing decade of the nineteenth century. None of us really knew anything about it except what Stonewall taught us. If some new incomprehensible announcement appeared in the newspapers we skipped it, being sure that Edmund would make it all clear at the club in the evening. He made us understand, in a dim way, that some vast, tremendous secret lay behind it all. I recall his saying, on one occasion, not long before the blow fell:
"Listen to this! Here's Professor Thomson declaring that a single grain of radium contains in its padlocked atoms energy enough to lift a million tons three hundred yards high. Professor Thomson is too modest in his estimates, and he hasn't the ghost of an idea how to get at that energy. Neither has Professor Rutherford, nor Lord Kelvin; but somebody will get at it, just the same."
He positively thrilled us when he spoke thus, for there was a look in his eyes which seemed to penetrate depths unfathomable to our intelligence. Yet we had not the faintest conception of what was really passing in his mind. If we had understood it, if we had caught a single clear glimpse of the workings of his intellect, we should have been appalled. And if we had known how close we stood to the verge of an abyss of mystery about to be lighted by such a gleam as had never before been emitted from the human spirit, I believe that we would have started from our chairs and fled in dismay.
But we understood nothing, except that Edmund was indulging in one of his eccentric dreams, and Jack, in his large, careless, good-natured way broke in with:
"Well, Edmund, suppose you could 'get at it,' as you say; what would you do with it?"
Stonewall's eyes gleamed for a moment, and then he replied, with a curious emphasis:
"I might do what Archimedes dreamed of."
None of us happened to remember what it was that Archimedes had dreamed, and the subject was dropped.
For a considerable time afterwards we saw nothing of Stonewall. He did not come to the club, and we were beginning to think of looking him up, when one evening, quite unexpectedly, he dropped in, wearing an unusually cheerful expression. We had greatly missed him, and we now greeted him with effusion. His animation impressed us all, and he had no sooner shaken hands than he said, with suppressed excitement in his voice:
"Well, I've 'got at it.'"
"Got at what?" drawled Jack.
"The inter-atomic energy. I've got it under control."
"The deuce you have!" said Jack.
"Yes, I've arrived where a certain professor dreamed of being when he averred that 'when man knows that every breath of air he draws has contained within itself force enough to drive the workshops of the world he will find out some day, somehow, some way of tapping that energy.' The thing is done, for I've tapped it!"
We stared at one another, not knowing what to say, except Jack, who, inspired by the spirit of mischief, drawled out:
"Ah, yes, I remember. Well then, Edmund, as I asked you before, what are you going to do with it?"
There was not really any thought among us of poking fun at Edmund; we respected and admired him far too much for that; nevertheless, catching the infection of banter from Jack, we united in demanding, in a manner which I can now see must have appeared most provoking:
"Why, yes, Edmund, tell us what you are going to do with it."
And then Jack added fuel by mockingly, though with perfectly good-natured intention, taking Edmund by the hand and swinging him in front of us with:
"Gentlemen, Archimedes junior."
Stonewall's eyes flashed and his cheek darkened, but for a moment he said nothing. Presently, with a return of his former affability, he said:
"I wish you would come over to the laboratory and let me show you what I am going to do."
Of course we instantly assented. Nothing could have pleased us better than this invitation, for we had long been dying to see the inside of Edmund's laboratory. We all got our hats and started out with him. We knew where he lived, occupying a whole house though he was a bachelor, but none of us had ever seen the inside of it, and our curiosity was on the qui vive. He led us through a handsome hallway and a rear apartment directly into the back yard, half of which we were surprised to find inclosed and roofed over, forming a huge shanty, like a workshop. Edmund opened the door of the shanty and ushered us in.
A remarkable object at once concentrated our attention. In the center of the place was the queerest-looking thing that you can well imagine. I can hardly describe it. It was round and elongated like a boiler, with bulging ends, and seemed to be made of polished steel. Its total length was about eighteen feet, and its width ten feet. Edmund approached it and opened a door in the end, which was wide and high enough for us to enter without stooping or crowding.
"Step in, gentlemen," he said, and unhesitatingly we obeyed him, all except Church, who for some unknown reason remained outside, and when we looked for him had disappeared.
Edmund turned on a bright light, and we found ourselves in an oblong chamber, beautifully fitted up with polished woodwork, and leather-cushioned seats running round the sides. Many metallic knobs and handles shone on the walls.
"Sit down," said Edmund, "and I will tell you what I have got here."
He stepped to the door and called again for Church but there was no answer. We concluded that, thinking the thing would be too deep to be interesting, he had gone back to the club. That was not what he had done, as you will learn later, but he never regretted what he did do. Getting no response from Church, Edmund finally sat down with us on one of the leather-covered benches, and began his explanation.
"As I was telling you at the club," he said, "I've solved the mystery of the atoms. I'm sure you'll excuse me from explaining my method" (there was a little raillery in his manner), "but at least you can understand the plain statement that I've got unlimited power at my command. These knobs and handles that you see are my keys for turning it on and off, and controlling it as I wish. Mark you, this power comes right out of the heart of what we call matter; the world is chock full of it. We have known that it was there at least ever since radioactivity was discovered, but it looked as though human intelligence would never be able to set it free from its prison. Nevertheless I have not only set it free, but I am able to control it as perfectly as if it were steam from a boiler, or an electric current from a dynamo."
Jack, who was as unscientific a person as ever lived, yawned, and Edmund noticed it. But he showed no irritation, merely smiling, and saying, with a wink at me and Henry:
"Even this seems to be rather too deep, so perhaps I had better show you, instead of telling you, what I mean. Excuse me a moment."
He stepped out of the door, and we remained seated. We heard a noise outside like the opening of a barn door, and immediately Edmund reappeared and closed the door of the chamber in which we were. We watched him with growing curiosity. With a singular smile he pressed a knob on the wall, and instantly we felt that the chamber was rising in the air. It rocked a little like a boat in wavy water. We were startled, of course, but not alarmed.
"Hello!" exclaimed Jack. "What kind of a balloon is this?"
"It's something more than a balloon," was Edmund's reply, and as he spoke he touched another knob, and we felt the car, as I must now call it, come to rest. Then Edmund opened a shutter at one side, and we all sprang up to look out. Below us we saw roofs and the tops of two trees standing at the side of the street.
"We're
