e were in the angle of the far corner of the chamber, a fact that
accounted for our not having noticed the hollow sound of the place
during our former exhaustive examination. As the match burnt we
scrutinised the spot. There was a join in the solid rock floor, and,
great heavens! there, let in level with the rock, was a stone ring. We
said no word, we were too excited, and our hearts beat too wildly with
hope to allow us to speak. Good had a knife, at the back of which was
one of those hooks that are made to extract stones from horses' hoofs.
He opened it, and scratched round the ring with it. Finally he worked
it under, and levered away gently for fear of breaking the hook. The
ring began to move. Being of stone it had not rusted fast in all the
centuries it had lain there, as would have been the case had it been of
iron. Presently it was upright. Then he thrust his hands into it and
tugged with all his force, but nothing budged.

"Let me try," I said impatiently, for the situation of the stone, right
in the angle of the corner, was such that it was impossible for two to
pull at once. I took hold and strained away, but no results.

Then Sir Henry tried and failed.

Taking the hook again, Good scratched all round the crack where we felt
the air coming up.

"Now, Curtis," he said, "tackle on, and put your back into it; you are
as strong as two. Stop," and he took off a stout black silk
handkerchief, which, true to his habits of neatness, he still wore, and
ran it through the ring. "Quatermain, get Curtis round the middle and
pull for dear life when I give the word. _Now._"

Sir Henry put out all his enormous strength, and Good and I did the
same, with such power as nature had given us.

"Heave! heave! it's giving," gasped Sir Henry; and I heard the muscles
of his great back cracking. Suddenly there was a grating sound, then a
rush of air, and we were all on our backs on the floor with a heavy
flag-stone upon the top of us. Sir Henry's strength had done it, and
never did muscular power stand a man in better stead.

"Light a match, Quatermain," he said, so soon as we had picked
ourselves up and got our breath; "carefully, now."

I did so, and there before us, Heaven be praised! was the _first step
of a stone stair._

"Now what is to be done?" asked Good.

"Follow the stair, of course, and trust to Providence."

"Stop!" said Sir Henry; "Quatermain, get the bit of biltong and the
water that are left; we may want
