“What do you think of that water falling, Christopher?” I asked.

He waited a long time, and his slow answer chilled me:

“I don’t know, sir.”

“You’ll go slow when we come nearer?”

“Yes, sir.”

Beelo gave me a hand-pressure intended to silence my foolish tongue.

With a growing intensity in the odor, in the furnace roar, and in the rumbling of the waterfall, came stealing something new and surpassingly uncanny. It was a very dim glow, with no visible source, and without the power to make anything seen but itself. Apparently it was but the darkness in a more oppressive phase. In vain did I strain my eyes to see Christopher, Beelo, the raft, the water,—anything that light could make visible; but the glow was as impenetrable as the darkness.

Beelo was going to pieces under the weight of this encompassing awe. I knew that his weakness was born of his yielding to an extraneous reliance—Christopher and me. He put his lips to my ear and whispered:

“I’m afraid.”

“Steady, lad. You are our guide; you are responsible for us.”
