When, however, I had almost quenched my ravenous thirst, I made a discovery.
“Why, it is ferruginous water.”
“Most excellent stomachic,” replied my uncle, “and highly mineralized. Here is a journey worth twenty to Spa.”
“It’s very good,” I replied.
“I should think so. Water found six miles under ground. There is a peculiarly inky flavor to it, which is by no means disagreeable. Hans may congratulate himself on having made a rare discovery. What do you say, nephew, according to the usual custom of travelers, to name the stream after him?”
“Good,” said I.
And the name of “Hansbach” was at once agreed upon.
Hans was not a bit more proud after hearing our determination than he was before. After having taken a very small modicum of the welcome refreshment, he had seated himself in a corner with his usual imperturbable gravity.
“Now,” said I, “it is not worth while letting this water run to waste.”
“What is the use,” replied my uncle, “the source from which this river rises is inexhaustible.”
“Never mind,” I continued, “let us fill our goatskin and gourds, and then try to stop the opening up.”
My advice, after some hesitation, was followed or attempted to be followed. Hans picked up all the broken pieces of granite he had knocked out, and using some tow he happened to have about him, tried to shut up the fissure he had made in the wall. All he did was to scald his hands. The pressure was too great, and all our attempts were utter failures.
“It is evident,” I remarked, “that the upper surface of these springs is situated at a very great height above—as we may fairly infer from the great pressure of the jet.”
“That is by no means doubtful,” replied my uncle, “if this column of water is about thirty-two thousand feet high, the atmospheric pressure must be something enormous. But a new idea has just struck me.”
“And what is that?”
“Why be at so much trouble to close this aperture?”
“Because—”
I hesitated and stammered, having no real reason.
“When our water bottles are empty, we are not at all sure that we shall be able to fill them,” observed my uncle.
“I think that is very probable.”
“Well, then, let this water run. It will, of course, naturally follow in our track, and will serve to guide and refresh us.”
“I think the idea is a good one,” I cried in reply, “and with this rivulet as a companion, there is no further reason why we should not succeed in our marvelous project.”
“Ah, my boy,” said the Professor, laughing, “after all, you are coming around.”
“More than that, I am now confident of ultimate success. Forward.”
“One moment, nephew mine. Let us begin by taking some hours of repose.”
I had utterly forgotten that it was night. The chronometer, however, informed me of the fact. Soon we were sufficiently restored and refreshed, and had all fallen into a profound sleep.

Under the Ocean
By the next day we had 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 going around by sinuous and winding ways, presented every now and then sharp turns, and in fact had all the appearance of a labyrinth. Its direction, however, was in general toward the southwest. My uncle made several pauses in order to consult his compass.
