"The torch! The torch!" cried the Professor.

Not without difficulty Hans succeeded in lighting the torch; and the flame, preserving its upward tendency, threw enough light to show us what kind of a place we were in.

"Just as I thought," said the Professor "We are in a tunnel not four-and-twenty feet in diameter. The water had reached the bottom of the gulf. It is now rising to its level, and carrying us with it."

"Where to?"

"I cannot tell; but we must be ready for anything. We are mounting at a speed which seems to me of fourteen feet in a second, or ten miles an hour. At this rate we shall get on."

"Yes, if nothing stops us; if this well has an aperture. But suppose it to be stopped. If the air is condensed by the pressure of this column of water we shall be crushed."

"Axel," replied the Professor with perfect coolness, "our situation is almost desperate; but there are some chances of deliverance, and it is these that I am considering. If at every instant we may perish, so at every instant we may be saved. Let us then be prepared to seize upon the smallest advantage."

"But what shall we do now?"

"Recruit our strength by eating."
