A sudden jolt threw me down. The Nautilus had just struck a reef, and it remained motionless, listing slightly to port.

When I stood up, I saw Captain Nemo and his chief officer on the platform. They were examining the ship’s circumstances, exchanging a few words in their incomprehensible dialect.

Here is what those circumstances entailed. Two miles to starboard lay Gueboroa Island, its coastline curving north to west like an immense arm. To the south and east, heads of coral were already on display, left uncovered by the ebbing waters. We had run aground at full tide and in one of those seas whose tides are moderate, an inconvenient state of affairs for floating the Nautilus off. However, the ship hadn’t suffered in any way, so solidly joined was its hull. But although it could neither sink nor split open, it was in serious danger of being permanently attached to these reefs, and that would have been the finish of Captain Nemo’s submersible.

I was mulling this over when the captain approached, cool and calm, forever in control of himself, looking neither alarmed nor annoyed.

“An accident?” I said to him.

“No, an incident,” he answered me.

“But an incident,” I replied, “that may oblige you to become a resident again of these shores you avoid!”

Captain Nemo gave me an odd look and gestured no. Which told me pretty clearly that nothing would ever force him to set foot on a land mass again. Then he said:

“No, Professor Aronnax, the Nautilus isn’t consigned to perdition. It will still carry you through the midst of the ocean’s wonders. Our voyage is just beginning, and I’ve no desire to deprive myself so soon of the pleasure of your company.”

“Even so, Captain Nemo,” I went on, ignoring his ironic turn of phrase, “the Nautilus has run aground at a moment when the sea is full. Now then, the tides aren’t strong in the Pacific, and if you can’t unballast the Nautilus, which seems impossible to me, I don’t see how it will float off.”
