"Let us be moving," I cried, awakening the echoes of the old world.

We resumed our march on Thursday at eight o'clock in the morning. The great granite tunnel, as it went round by sinuous and winding ways, presented every now and then sharp turns, and in fact all the appearance of a labyrinth. Its direction, however, was in general towards the southwest. My uncle made several pauses in order to consult his compa.s.s.

The gallery now began to trend downwards in a horizontal direction, with about two inches of fall in every furlong. The murmuring stream flowed quietly at our feet. I could not but compare it to some familiar spirit, guiding us through the earth, and I dabbled my fingers in its tepid water, which sang like a naiad as we progressed. My good humor began to a.s.sume a mythological character.

As for my uncle he began to complain of the horizontal character of the road. His route, he found, began to be indefinitely prolonged, instead of "sliding down the celestial ray," according to his expression.

But we had no choice; and as long as our road led towards the centre--however little progress we made, there was no reason to complain.

Moreover, from time to time the slopes were much greater, the naiad sang more loudly, and we began to dip downwards in earnest.

As yet, however, I felt no painful sensation. I had not got over the excitement of the discovery of water.

That day and the next we did a considerable amount of horizontal, and relatively very little vertical, traveling.

On Friday evening, the tenth of July, according to our estimation, we ought to have been thirty leagues to the southeast of Reykjavik, and about two leagues and a half deep. We now received a rather startling surprise.

Under our feet there opened a horrible well. My uncle was so delighted that he actually clapped his hands--as he saw how steep and sharp was the descent.

"Ah, ah!" he cried, in rapturous delight; "this will take us a long way.

Look at the projections of the rock. Hah!" he exclaimed, "it's a fearful staircase!"

Hans, however, who in all our troubles had never given up the ropes, took care so to dispose of them as to prevent any accidents. Our descent then began. I dare not call it a perilous descent, for I was already too familiar with that sort of work to look upon it as anything but a very ordinary affair.

This well was a kind of narrow opening in the ma.s.sive granite of the kind known as a fissure. The contraction of the terrestrial scaffolding, when it suddenly cooled, had been evidently the cause. If it had ever served in former times as a kind of funnel through which pa.s.sed the eruptive ma.s.ses vomited by Sneffels, I was at a loss to explain how it had left no mark. We were, in fact, descending a spiral, something like those winding staircases in use in modern houses.

We were compelled every quarter of an hour or thereabouts to sit down in order to rest our legs. Our calves ached. We then seated ourselves on some projecting rock with our legs hanging over, and gossiped while we ate a mouthful--drinking still from the pleasantly warm running stream which had not deserted us.

It is scarcely necessary to say that in this curiously shaped fissure the Hansbach had become a cascade to the detriment of its size. It was still, however, sufficient, and more, for our wants. Besides we knew that, as soon as the declivity ceased to be so abrupt, the stream must resume its peaceful course. At this moment it reminded me of my uncle, his impatience and rage, while when it flowed more peacefully, I pictured to myself the placidity of the Icelandic guide.

During the whole of two days, the sixth and seventh of July, we followed the extraordinary spiral staircase of the fissure, penetrating two leagues farther into the crust of the earth, which put us five leagues below the level of the sea. On the eighth, however, at twelve o'clock in the day, the fissure suddenly a.s.sumed a much more gentle slope still trending in a southeast direction.

The road now became comparatively easy, and at the same time dreadfully monotonous. It would have been difficult for matters to have turned out otherwise. Our peculiar journey had no chance of being diversified by landscape and scenery. At all events, such was my idea.

At length, on Wednesday the fifteenth, we were actually seven leagues (twenty-one miles) below the surface of the earth, and fifty leagues distant from the mountain of Sneffels. Though, if the truth be told, we were very tired, our health had resisted all suffering, and was in a most satisfactory state. Our traveler's box of medicaments had not even been opened.

My uncle was careful to note every hour the indications of the compa.s.s, of the manometer, and of the thermometer, all which he afterwards published in his elaborate philosophical and scientific account of our remarkable voyage. He was therefore able to give an exact relation of the situation. When, therefore, he informed me that we were fifty leagues in a horizontal direction distant from our starting point, I could not suppress a loud exclamation.

"What is the matter now?" cried my uncle.

"Nothing very important, only an idea has entered my head," was my reply.

"Well, out with it, My boy."

"It is my opinion that if your calculations are correct we are no longer under Iceland."

"Do you think so?"

"We can very easily find out," I replied, pulling out a map and compa.s.ses.

"You see," I said, after careful measurement, "that I am not mistaken.

We are far beyond Cape Portland; and those fifty leagues to the southeast will take us into the open sea."

"Under the open sea," cried my uncle, rubbing his hands with a delighted air.

"Yes," I cried, "no doubt old Ocean flows over our heads!"

"Well, my dear boy, what can be more natural! Do you not know that in the neighborhood of Newcastle there are coal mines which have been worked far out under the sea?"

Now my worthy uncle, the Professor, no doubt regarded this discovery as a very simple fact, but to me the idea was by no means a pleasant one.

And yet when one came to think the matter over seriously, what mattered it whether the plains and mountains of Iceland were suspended over our devoted heads, or the mighty billows of the Atlantic Ocean? The whole question rested on the solidity of the granite roof above us. However, I soon got used to the ideal for the pa.s.sage now level, now running down, and still always to the southeast, kept going deeper and deeper into the profound abysses of Mother Earth.

Three days later, on the eighteenth day of July, on a Sat.u.r.day, we reached a kind of vast grotto. My uncle here paid Hans his usual rix-dollars, and it was decided that the next day should be a day of rest.

CHAPTER 22

SUNDAY BELOW GROUND

I Awoke on Sunday morning without any sense of hurry and bustle attendant on an immediate departure. Though the day to be devoted to repose and reflection was spent under such strange circ.u.mstances, and in so wonderful a place, the idea was a pleasant one. Besides, we all began to get used to this kind of existence. I had almost ceased to think of the sun, of the moon, of the stars, of the trees, houses, and towns; in fact, about any terrestrial necessities. In our peculiar position we were far above such reflections.

The grotto was a vast and magnificent hall. Along its granitic soil the stream flowed placidly and pleasantly. So great a distance was it now from its fiery source that its water was scarcely lukewarm, and could be drunk without delay or difficulty.

After a frugal breakfast, the Professor made up his mind to devote some hours to putting his notes and calculations in order.

"In the first place," he said, "I have a good many to verify and prove, in order that we may know our exact position. I wish to be able on our return to the upper regions to make a map of our journey, a kind of vertical section of the globe, which will be, as it were, the profile of the expedition."

"That would indeed be a curious work, Uncle; but can you make your observations with anything like certainty and precision?"

"I can. I have never on any occasion failed to note with great care the angles and slopes. I am certain as to having made no mistake. Take the compa.s.s and examine how she points."

I looked at the instrument with care.

"East one quarter southeast."

"Very good," resumed the Professor, noting the observation, and going through some rapid calculations. "I make out that we have journeyed two hundred and fifty miles from the point of our departure."

"Then the mighty waves of the Atlantic are rolling over our heads?"

"Certainly."

"And at this very moment it is possible that fierce tempests are raging above, and that men and ships are battling against the angry blasts just over our heads?"

"It is quite within the range of possibility," rejoined my uncle, smiling.

"And that whales are playing in shoals, thrashing the bottom of the sea, the roof of our adamantine prison?"
