"Rather risky," said I.
"Yes. It burst, and smashed all my windows and a lot of my apparatus; but I got a kind of
diamond powder nevertheless. Following out the problem of getting a big pressure upon the
molten mixture from which the things were to crystallise, I hit upon some researches of
Daubree's at the Paris Laboratorie des Poudres et Salpetres. He exploded dynamite in a
tightly screwed steel cylinder, too strong to burst, and I found he could crush rocks into a
muck not unlike the South African bed in which diamonds are found. It was a tremendous
strain on my resources, but I got a steel cylinder made for my purpose after his pattern. I put
in all my stuff and my explosives, built up a fire in my furnace, put the whole concern in,
and--went out for a walk."
I could not help laughing at his matter-of-fact manner. "Did you not think it would blow up
the house? Were there other people in the place?"
"It was in the interest of science," he said, ultimately. "There was a costermonger family on
the floor below, a begging-letter writer in the room behind mine, and two flower-women
were upstairs. Perhaps it was a bit thoughtless. But possibly some of them were out.
"When I came back the thing was just where I left it, among the white-hot coals. The
explosive hadn't burst the case. And then I had a problem to face. You know time is an
important element in crystallisation. If you hurry the process the crystals are small--it is
only by prolonged standing that they grow to any size. I resolved to let this apparatus cool
for two years, letting the temperature go down slowly during the time. And I was now quite
out of money; and with a big fire and the rent of my room, as well as my hunger to satisfy, I
had scarcely a penny in the world.
"I can hardly tell you all the shifts I was put to while I was making the diamonds. I have
sold newspapers, held horses, opened cab-doors. For many weeks I addressed envelopes. I
had a place as assistant to a man who owned a barrow, and used to call down one side of
the road while he called down the other.
"Once for a week I had absolutely nothing to do, and I begged. What a week that was! One
day the fire was going out and I had eaten nothing all day, and a little chap taking his girl
out, gave me sixpence--to show off. Thank heaven for vanity! How the fish-shops smelt!
But I went and spent it all on coals, and had the furnace bright red again, and then--Well,
hunger makes a fool of a man.
"At last, three weeks ago, I let the fire out. I took my cylinder and unscrewed it while it was
still so hot that it punished my hands, and I scraped out the crumbling lava-like mass with a
chisel, and hammered it into a powder upon an iron plate. And I found three big diamonds
and five small ones. As I sat on the floor hammering, my door opened, and my neighbour,
the begging-letter writer came in. He was drunk--as he usually is. "'Nerchist,' said he.
'You're drunk,' said I. ''Structive scoundrel,' said he. 'Go to your father,' said I, meaning the
Father of Lies. 'Never you mind,' said he, and gave me a cunning wink, and hiccuped, and
leaning up against the door, with his other eye against the door-post, began to babble of
how he had been prying in my room, and how he had gone to the police that morning, and
how they had taken down everything he had to say--''siffiwas a ge'm,' said he. Then I
suddenly realised I was in a hole. Either I should have to tell these police my little secret,
