leading to no result; and, suspending further operations in the shaft, we returned to the more familiar parts of the mine.

All the rest of that day the engineer seemed preoccupied by some absorbing thought. He was unusually taciturn, and there was a scared, bewildered look in his eyes, as that of a man who has seen a ghost. At night, as we two were sitting alone in the lodging we shared together near the mouth of the mine, I said to my friend,—

"Tell me frankly what you saw in that chasm: I am sure it was something strange and terrible. Whatever it be, it has left your mind in a state of doubt. In such a case two heads are better than one. Confide in me."

The engineer long endeavoured to evade my inquiries; but as, while he spoke, he helped himself unconsciously out of the brandy-flask to a degree to which he was wholly unaccustomed, for he was a very temperate man, his reserve gradually melted away. He who would keep himself to himself should imitate the dumb animals, and drink water. At last he said, "I will tell you all. When the cage stopped, I found myself on a ridge of rock; and below me, the chasm, taking a slanting direction, shot down to a considerable depth, the darkness of which my lamp could not have penetrated. But through it, to my infinite surprise, streamed upward a steady brilliant light. Could it be any volcanic fire? In that case, surely I should have felt the heat. Still, if on this there was doubt, it was of the utmost importance to our common safety to clear it up. I examined the sides of the descent, and found that I could venture to trust myself to the irregular projection of ledges, at least for some way. I left the cage and clambered down. As I drew nearer and nearer to the light, the chasm became wider, and at last I saw, to my unspeakable amaze, a broad level road at the bottom of the abyss, illumined as far as the eye could reach by what seemed artificial gas-lamps placed at regular intervals, as in the thoroughfare of a great city; and I heard confusedly at a distance a hum as of human voices. I know, of course, that no rival miners are at work in this district. Whose could be those voices? What human hands could have levelled that road and marshalled those lamps?

"The superstitious belief, common to miners, that gnomes or fiends dwell within the bowels of the earth, began to seize me. I shuddered at the thought of descending further and braving the inhabitants of this nether valley. Nor indeed could I have done so without ropes, as from the spot I had reached to the bottom of the chasm the sides of the rock sank down abrupt, smooth, and sheer. I retraced my steps with some difficulty. Now I have told you all."

"You will descend again?"

"I ought, yet I feel as if I durst not."

"A trusty companion halves the journey and doubles the courage. I will go with you. We will provide ourselves with ropes of suitable length and strength—and—pardon me—you must not drink more to-night, our hands and feet must be steady and firm tomorrow."

Chapter II.

With the morning my friend's nerves were rebraced, and he was not less excited by curiosity than myself. Perhaps more; for he evidently believed in his own story, and I felt considerable doubt of it; not that he would have wilfully told an untruth, but that I thought he must have been under one of those hallucinations which seize on our fancy or our nerves in solitary, unaccustomed places, and in which we give shape to the formless and sound to the dumb.

We selected six veteran miners to watch our descent; and as the cage held only one at a time, the engineer descended first; and when he had gained the ledge at which he had before halted, the cage rearose for me. I soon gained his side. We had provided ourselves with a strong coil of rope.

The light struck on my sight as it had done the day before on my friend's. The hollow through which it came sloped diagonally: it seemed to me a diffused atmospheric light, not like that from fire, but soft and silvery, as from a northern star. Quitting the cage, we descended, one after the other, easily enough, owing to the juts in the side, till we reached the place at which my friend had previously halted, and which was a projection just spacious enough to allow us to stand abreast. From this spot the chasm widened rapidly like the lower end of a vast funnel, and I saw distinctly the valley, the road, the lamps which my companion had described. He had exaggerated nothing. I heard the sounds he had heard—a mingled indescribable hum as of voices and a dull tramp as of feet. Straining my eye farther down, I clearly beheld at a distance the outline of some large building. It could not be mere natural rock, it was too symmetrical, with huge heavy Egyptian-like columns, and the whole lighted as from within. I had about me a small pocket-telescope, and by the aid of this, I could distinguish, near the building I mention, two forms which seemed human, though I could not be sure. At least they were living, for they moved, and both vanished within the building. We now proceeded to attach the end of the rope we had brought with us to the ledge on which we stood, by the aid of clamps and grappling hooks, with which, as well as with necessary tools, we were provided.

We were almost silent in our work. We toiled like men afraid to speak to each other. One end of the rope being thus apparently made firm to the ledge, the other, to which we fastened a fragment of the rock, rested on the ground below, a distance of some fifty feet. I was a younger man and a more active man than my companion, and having served on board ship in my boyhood, this mode of transit was more familiar to me than to him. In a whisper I claimed the precedence, so that when I gained the ground I might serve to hold the rope more steady for his descent. I got safely to the ground beneath, and the engineer now began to lower himself. But he had scarcely accomplished ten feet of the descent, when the fastenings, which we had fancied so secure, gave way, or rather the rock itself proved treacherous and crumbled beneath the strain; and the unhappy man was precipitated to the bottom, falling just at my feet, and bringing down with his fall splinters of the rock, one of which, fortunately but a small one, struck and for the time stunned me. When I recovered my senses I saw my companion an inanimate mass beside me, life utterly extinct. While I was bending over his corpse in grief and horror, I heard close at hand a strange sound between a snort and a hiss; and turning instinctively to the quarter from which it came, I saw emerging from a dark fissure in the rock a vast and terrible head, with open jaws and dull, ghastly, hungry eyes—the head of a monstrous reptile resembling that of the crocodile or alligator, but infinitely larger than the largest creature of that kind I had ever beheld in my travels. I started to my feet and fled down the valley at my utmost speed. I stopped at last, ashamed of my panic and my flight, and returned to the spot on which I had left the body of my friend. It was gone; doubtless the monster had already drawn it into its den and devoured it. The rope and the grappling-hooks still lay where they had fallen, but they afforded me no chance of return; it was impossible to re-attach them to the rock above, and the sides of the rock were too sheer and smooth for human steps to clamber. I was alone in this strange world, amidst the bowels of the earth.

Chapter III.

Slowly and cautiously I went my solitary way down the lamplit road and towards the large building I have described. The road itself seemed like a great Alpine pass, skirting rocky mountains of which the one through whose chasm I had descended formed a link. Deep below to the left lay a vast valley, which presented to my astonished eye the unmistakeable evidences
