ore along the rocky walls. I
remember that I laid down the basket full of diamonds, wishing to be
rid of its weight, but on second thoughts took it up again. One might
as well die rich as poor, I reflected. As we went the sound became more
and more audible, till at last it seemed quite loud in the quiet. On,
yet on; now we could distinctly make out the unmistakable swirl of
rushing water. And yet how could there be running water in the bowels
of the earth? Now we were quite near it, and Good, who was leading,
swore that he could smell it.

"Go gently, Good," said Sir Henry, "we must be close." _Splash!_ and a
cry from Good.

He had fallen in.

"Good! Good! where are you?" we shouted, in terrified distress. To our
intense relief an answer came back in a choky voice.

"All right; I've got hold of a rock. Strike a light to show me where
you are."

Hastily I lit the last remaining match. Its faint gleam discovered to
us a dark mass of water running at our feet. How wide it was we could
not see, but there, some way out, was the dark form of our companion
hanging on to a projecting rock.

"Stand clear to catch me," sung out Good. "I must swim for it."

Then we heard a splash, and a great struggle. Another minute and he had
grabbed at and caught Sir Henry's outstretched hand, and we had pulled
him up high and dry into the tunnel.

"My word!" he said, between his gasps, "that was touch and go. If I
hadn't managed to catch that rock, and known how to swim, I should have
been done. It runs like a mill-race, and I could feel no bottom."

We dared not follow the banks of the subterranean river for fear lest
we should fall into it again in the darkness. So after Good had rested
a while, and we had drunk our fill of the water, which was sweet and
fresh, and washed our faces, that needed it sadly, as well as we could,
we started from the banks of this African Styx, and began to retrace
our steps along the tunnel, Good dripping unpleasantly in front of us.
At length we came to another gallery leading to our right.

"We may as well take it," said Sir Henry wearily; "all roads are alike
here; we can only go on till we drop."

Slowly, for a long, long while, we stumbled, utterly exhausted, along
this new tunnel, Sir Henry now leading the way. Again I thought of
abandoning that basket, but did not.

Suddenly he stopped, and we bumped up against him.

"Look!" he whispered, "is my brain going, or is that light?"

We stared
