“If high aims and high positions,” said I, “have their drawbacks of hard work and anxiety, they have their compensations. Influence, the power of doing good, of assisting those weaker and poorer than ourselves; and there is even a certain gratification in display …”
My banter under the circumstances was in very vile taste. I spoke on the spur of the contrast of his appearance and speech. I was sorry even while I was speaking.
He turned a haggard but very composed face upon me. Said he: “I forgot myself. Of course you would not understand.”
He measured me for a moment. “No doubt it is very absurd. You will not believe me even when I tell you, so that it is fairly safe to tell you. And it will be a comfort to tell someone. I really have a big business in hand, a very big business. But there are troubles just now. The fact is … I make diamonds.”
“I suppose,” said I, “you are out of work just at present?”
“I am sick of being disbelieved,” he said impatiently, and suddenly unbuttoning his wretched coat he pulled out a little canvas bag that was hanging by a cord round his neck. From this he produced a brown pebble. “I wonder if you know enough to know what that is?” He handed it to me.
Now, a year or so ago, I had occupied my leisure in taking a London science degree, so that I have a smattering of physics and mineralogy. The thing was not unlike an uncut diamond of the darker sort, though far too large, being almost as big as the top of my thumb. I took it, and saw it had the form of a regular octahedron, with the curved faces peculiar to the most precious of minerals. I took out my penknife and tried to scratch it—vainly. Leaning forward towards the gas-lamp, I tried the thing on my watch-glass, and scored a white line across that with the greatest ease.
I looked at my interlocutor with rising curiosity. “It certainly is rather like a diamond. But, if so, it is a Behemoth of diamonds. Where did you get it?”
“I tell you I made it,” he said. “Give it back to me.”
He replaced it hastily and buttoned his jacket. “I will sell it you for one hundred pounds,” he suddenly whispered eagerly. With that my suspicions returned. The thing might, after all, be merely a lump of that almost equally hard substance, corundum, with an accidental resemblance in shape to the diamond. Or if it was a diamond, how came he by it, and why should he offer it at a hundred pounds?
We looked into one another’s eyes. He seemed eager, but honestly eager. At that moment I believed it was a diamond he was trying to sell. Yet I am a poor man, a hundred pounds would leave a visible gap in my fortunes and no sane man would buy a diamond by gaslight from a ragged tramp on his personal warranty only. Still, a diamond that size conjured up a vision of many thousands of pounds. Then, thought I, such a stone could scarcely exist without being mentioned in every book on gems, and again I called to mind the stories of contraband and light-fingered Kaffirs at the Cape. I put the question of purchase on one side.
“How did you get it?” said I.
“I made it.”
I had heard something of Moissan, but I knew his artificial diamonds were very small. I shook my head.
“You seem to know something of this kind of thing. I will tell you a little about myself. Perhaps then you may think better of the purchase.” He turned round with his back to the river, and put his hands in his pockets. He sighed. “I know you will not believe me.”
“Diamonds,” he began—and as he spoke his voice lost its faint flavour of the tramp and assumed something of the easy tone of an educated man—“are to be made by throwing carbon out of combination in a suitable flux and under a suitable pressure; the carbon crystallises out, not as black-lead or charcoal-powder, but as small diamonds. So much has been known to chemists for years, but no one yet had hit upon exactly the right flux in which to melt up the carbon, or exactly the right pressure for the best results. Consequently the diamonds made by chemists are small and dark, and worthless as jewels. Now I, you know, have given up my life to this problem—given my life to it.
“I began to work at the conditions of diamond making when I was seventeen, and now I am thirty-two. It seemed to me that it might take all the thought and energies of a man for ten years, or twenty years, but, even if it did, the game was still worth the candle. Suppose one to have at last just hit the right trick before the secret got out and diamonds became as common as coal, one might realize millions. Millions!”
He paused and looked for my sympathy. His eyes shone hungrily. “To think,” said he, “that I am on the verge of it all, and here!
“I had,” he proceeded, “about a thousand pounds when I was twenty-one, and this, I thought, eked out by a little teaching, would keep my researches going. A year or two was spent in study, at Berlin chiefly, and then I continued on my own account. The trouble was the secrecy. You see, if once I had let out what I was doing, other men might have been spurred on by my belief in the practicability of the idea; and I do not pretend to be such a genius as to have been sure of coming in first, in the case of a race for the discovery. And you see it was important that if I really meant to make a pile, people should not
