THE WONDERS OF TERRESTRIAL DEPTHS At eight in the morning a ray of daylight came to wake us up.

The thousand shining surfaces of lava on the walls received it on its passage, and scattered it like a shower of sparks.
There was light enough to distinguish surrounding objects.
"Well, Axel, what do you say to it ?" cried my uncle, rubbing his hands.

We have not gone a single inch yet into the bowels of the earth." "What do you mean ?" "I mean that we have only reached the level of the island, long vertical tube, which terminates at the mouth of the crater, has its lower end only at the level of the sea." "Are you sure of that ?" "Quite sure.

"You see," said the Professor, "we have now only the pressure of our atmosphere, and I shall be glad when the aneroid takes the place of the barometer." And in truth this instrument would become useless as soon as the weight of the atmosphere should exceed the pressure ascertained at the level of the sea.
"But," I said, "is there not reason to fear that this ever-increasing pressure will become at last very painful to bear ?" "No; we shall descend at a slow rate, and our lungs will become inured to a denser atmosphere.

Aeronauts find the want of air as they rise to high elevations, but we shall perhaps have too much: of the two, this is what I should prefer.
