At six in the morning I rose. The hatches had not been opened. The inner air was not renewed, but the reservoirs, filled ready for any emergency, were now resorted to, and discharged several cubic feet of oxygen into the exhausted atmosphere of the Nautilus.

I worked in my room till noon, without having seen Captain Nemo, even for an instant. On board no preparations for departure were visible.

I waited still some time, then went into the large saloon. The clock marked half-past two. In ten minutes it would be high-tide: and, if Captain Nemo had not made a rash promise, the Nautilus would be immediately detached. If not, many months would pass ere she could leave her bed of coral.

However, some warning vibrations began to be felt in the vessel. I heard the keel grating against the rough calcareous bottom of the coral reef.

At five-and-twenty minutes to three, Captain Nemo appeared in the saloon.

“We are going to start,” said he.

“Ah!” replied I.

“I have given the order to open the hatches.”

“And the Papuans?”

“The Papuans?” answered Captain Nemo, slightly shrugging his shoulders.

“Will they not come inside the Nautilus?”

“How?”

“Only by leaping over the hatches you have opened.”

“M. Aronnax,” quietly answered Captain Nemo, “they will not enter the hatches of the Nautilus in that way, even if they were open.”

I looked at the Captain.

“You do not understand?” said he.

“Hardly.”

“Well, come and you will see.”

I directed my steps towards the central staircase. There Ned Land and Conseil were slyly watching some of the ship’s crew, who were opening the hatches, while cries of rage and fearful vociferations resounded outside.

The port lids were pulled down outside. Twenty horrible faces appeared. But the first native who placed his hand on the stair-rail, struck from behind by some invisible force, I know not what, fled, uttering the most fearful cries and making the wildest contortions.

Ten of his companions followed him. They met with the same fate.

Conseil was in ecstasy. Ned Land, carried away by his violent instincts, rushed on to the staircase. But the moment he seized the rail with both hands, he, in his turn, was overthrown.

“I am struck by a thunderbolt,” cried he, with an oath.

This explained all. It was no rail; but a metallic cable charged with electricity from the deck communicating with the platform. Whoever touched it felt a powerful shock— and this shock would have been mortal if Captain Nemo had discharged into the conductor the whole force of the current. It might truly be said that between his assailants and himself he had stretched a network of electricity which none could pass with impunity.

Meanwhile, the exasperated Papuans had beaten a retreat paralysed with terror. As for us, half laughing, we consoled and rubbed the unfortunate Ned Land, who swore like one possessed.
