rom the grate a lump of coal about the
size of a billiard ball, he laid it upon the table.

"This," he said, "is nearly pure carbon, and as you are well aware it is
practically what a diamond is. Now, I will illustrate to you how you may
make a diamond from this piece of coal, which will be as good as any
diamond ever found in the mines. We will manufacture it instead of
letting nature do it.

"We will first place it in this glass bowl, and pour over it sufficient
liquid air to cover it completely. We will let it remain until it is
thoroughly cold, say, at least 200 degrees below zero; there--now all we
have to do is to heat it and then subject it to a powerful--Great Gee

twelve. But I say, old fellow, just hold it under the blowpipe and get
it hot--just as hot as you can; I will be back soon--ta-ta." His last
words came to me faintly through the window--he had already floated out.

I took the queer-colored piece of coal, and began heating it under the

first taking the powder, and I think I went to sleep. How long I slept I
do not know, but I was startled at finding myself floating about the
room with much the same feeling as one has when floating in water, only
it was without effort. My motion seemed to be governed entirely by my
will,--if I glanced at anything in the room I would float towards it.
Imagine my astonishment at seeing my body lying in the bed apparently
sound asleep; you will admit the sensation was novel, to say the least.

After floating around the room two or three times enjoying the peculiar
sensation, I began to wonder what they had been doing at the hospital
during my absence. Immediately I found myself in the hospital ward. Dr.
Ford and two nurses were standing by
