on its subterrene course occurred to her. As she did not speak, but merely drew closer to me, and held fast my hand, I had no idea of her real distress till we were actually at the mouth of the black and very frightful-looking passage, and the pilot had lighted the electric lamp. As the boat shot under the arch she could not repress a cry of terror. Naturally putting my arm round her at this sign of alarm, I felt that she was trembling violently, and a single look, despite her veil, convinced me that she was crying, though in silence and doing her utmost to conceal her tears.
"Are you so frightened, child?" I asked. "I have been through many subterranean passages, though none so long and dark as this. But you see our lamp lights up not only the boat but the whole vault around and before us, and there can be no danger whatever."
"I am frightened, though," she said, "I cannot help it. I never saw anything of the kind before; and the darkness behind and before us, and the black water on either side, do make me shiver."
"Stop!" I called to the boatman.
"Now, Eveena," I said, "I do not care to persist in this journey if it really distresses you. I wished to see so wonderful a work of engineering; but, after all, I have been in a much uglier and more wonderful place, and I can see nothing here stranger than when I was rowed for three-quarters of a mile on the river in the Mammoth Cave. In any case I shall see little but a continuation of what I see already; so if you cannot bear it, we will go back."
By this time Esmo, who had been in the bows, had joined us, wishing to know why I had stopped the boat.
