We left the saloon. There was no one in the library. At the center staircase, by the berths of the ship's crew, there was no one. I thought that Captain Nemo must be in the pilot's cage. It was best to wait. We all returned to the saloon. For twenty minutes we remained thus, trying to hear the slightest noise which might be made on board the Nautilus, when Captain Nemo entered. He seemed not to see us; his face, generally so impassive, showed signs of uneasiness. He watched the compass silently, then the manometer; and going to the planisphere, placed his finger on the spot representing the southern seas. I would not interrupt him, but, some minutes later, when he turned toward me, I said, using one of his own expressions in the Torres Straits:
"An incident? captain?"
"No, sir; an accident this time."
"Serious?"
"Perhaps."
"Is the danger immediate?"
"No."
"The Nautilus has stranded?"
"Yes."
"And this has happened—how?"
"From a caprice of nature, not from the ignorance of man. Not a mistake has been made in the working. But we cannot prevent equilibrium from producing its effects. We may brave human laws, but we cannot resist natural ones."
Captain Nemo had chosen a strange moment for uttering this philosophical reflection. On the whole, his answer helped me little.
"May I ask, sir, the cause of this accident?"
"An enormous block of ice, a whole mountain, has turned over," he replied. "When icebergs are undermined at their base by warmer water or reiterated shocks, their center of gravity rises, and the whole thing turns over. This is what has happened; one of these blocks, as it fell, struck the Nautilus, then, gliding under its hull, raised it with irresistible force, bringing it into beds which are not so thick, where it is lying on its side."
"But can we not get the Nautilus off by emptying its reservoirs, that it may regain its equilibrium?"
