By the next day we had nearly forgotten our past sufferings. The first sensation I experienced was surprise at not being thirsty, and I actually asked myself the reason. The running stream, which flowed in rippling wavelets at my feet, was the satisfactory reply.  
We breakfasted with a good appetite, and then drank our fill of the excellent water. I felt myself quite a new man, ready to go anywhere my uncle chose to lead. I began to think. Why should not a man as seriously convinced as my uncle, succeed, with so excellent a guide as worthy Hans, and so devoted a nephew as myself? These were the brilliant ideas which now invaded my brain. Had the proposition now been made to go back to the summit of Mount Sneffels, I should have declined the offer in a most indignant manner.
 
But fortunately there was no question of going up. We were about to descend farther into the interior of the earth.
 
"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 compass.
 
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 assume 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 massive 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 passed the eruptive masses 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 ourse............
