no account for use or ornament. We were rapidly approaching the foot of the hills, where the river made another and abrupt turn. At this point the produce of the whole upper valley is generally embarked, and supplies from all other quarters are here received and distributed. In consequence, a town large and important for this planet, where no one who can help it prefers the crowded street to the freedom and expanse of the country, had grown up, with about a hundred and fifty houses, and perhaps a thousand inhabitants. It was so much matter of course that voyagers should disembark to cross the hills or to pursue their journey along the upper part of the river by road, that half-a-dozen different partnerships made it their business to assist in the transfer of passengers and light wares. Ahead of us was a somewhat steep hill-slope, in the lower part of which a wall absolutely perpendicular had been cut by those who pierced the tunnel, the mouth of which was now clearly visible immediately before us. It was about twelve feet in height, and perhaps twenty feet in width. The stream, which, like nearly all Martial rivers, is wide and shallow, had during the last fifty miles of our course grown narrower, with a depth at the same time constantly lessening, so that some care was required on the part of the pilot to avoid running aground. A stream of twenty inches in depth, affording room for two boats to pass abreast, is considered navigable for vessels only carrying passengers; thirty inches are required to afford a course which for heavy freight is preferable to the road. Eveena had taken it for granted that we should disembark here, and it was not till we had come within a hundred yards of the landing-place—where the bank was perpendicular and levelled to a height above the water, which enabled passengers to step directly from the deck of the boat—without slackening our speed, that the possibility of our intending to accompany the boat 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."
