At eight o'clock the next morning, a faint kind of dawn of day awoke us. The thousand and one prisms of the lava collected the light as it passed and brought it to us like a shower of sparks.
We were able with ease to see objects around us.
"Well, Harry, my boy," cried the delighted Professor, rubbing his hands together, "what say you now? Did you ever pass a more tranquil night in our house in the Konigstrasse? No deafening sounds of cartwheels, no cries of hawkers, no bad language from boatmen or watermen!"
"Well, Uncle, we are quite at the bottom of this well--but to me there is something terrible in this calm."
"Why," said the Professor hotly, "one would say you were already beginning to be afraid. How will you get on presently? Do you know, that as yet, we have not penetrated one inch into the bowels of the earth."
"What can you mean, sir?"
"Quite sure. Consult the barometer." was my bewildered and astonished reply.
"I mean to say that we have only just reached the soil of the island itself. This long vertical tube, which ends at the bottom of the crater of Sneffels, ceases here just about on a level with the sea."
"Are you sure, sir?"
"Quite sure. Consult the barometer."
It was quite true that the mercury, after rising gradually in the instrument, as long as our descent was taking place, had stopped precisely at twenty-nine degrees.
"You perceive," said the Professor, "we have as yet only to endure the pressure of air. I am curious to replace the barometer by the manometer."
The barometer, in fact, was about to become useless--as soon as the weight of the air was greater than what was calculated as above the level of the ocean.
"But," said I, "is it not very much to be feared that this ever-increasing pressure may not in the end turn out very painful and inconvenient?"
"No," said he. "We shall descend very slowly, and our lungs will be gradually accustomed to breathe compressed air. It is well known that aeronauts have gone so high as to be nearly without air at all--why, then, should we not accustom ourselves to breathe when we have, say, a little too much of it? For myself, I am certain I shall prefer it. Let us not lose a moment. Where is the packet which preceded us in our descent?"
I smilingly pointed it out to my uncle. Hans had not seen it, and believed it caught somewhere above us: "Huppe" as he phrased it.
"Now," said my uncle, "let us breakfast, and break fast like people who have a long day's work before them."
Biscuit and dried meat, washed down by some mouthfuls of water flavored with Schiedam, was the material of our luxurious meal.
As soon as it was finished, my uncle took from his pocket a notebook, destined to be filled by memoranda of our travels. He had already placed his instruments in order, and this is what he wrote:
Monday, June 29th
Chronometer, 8h. 17 m. morning.
Barometer, 29.6 inches.
This last observation referred to the obscure gallery, and was indicated to us by the compass.
"Now, Harry," cried the Professor, in an enthusiastic tone of voice, "we are truly about to take our first step into the Interior of the Earth; never before visited by man since the first creation of the world. You may consider, therefore, that at this precise moment our travels really commence."
