On January 18 the Nautilus lay in longitude 105 degrees and latitude 15 degrees south. The weather was threatening, the sea rough and billowy. The wind was blowing a strong gust from the east. The barometer, which had been falling for some days, forecast an approaching struggle of the elements.

I had climbed onto the platform just as the chief officer was taking his readings of hour angles. Out of habit I waited for him to pronounce his daily phrase. But that day it was replaced by a different phrase, just as incomprehensible. Almost at once I saw Captain Nemo appear, lift his spyglass, and inspect the horizon.

For some minutes the captain stood motionless, rooted to the spot contained within the field of his lens. Then he lowered his spyglass and exchanged about ten words with his chief officer. The latter seemed to be in the grip of an excitement he tried in vain to control. More in command of himself, Captain Nemo remained cool. Furthermore, he seemed to be raising certain objections that his chief officer kept answering with flat assurances. At least that's what I gathered from their differences in tone and gesture.

As for me, I stared industriously in the direction under observation but without spotting a thing. Sky and water merged into a perfectly clean horizon line.

Meanwhile Captain Nemo strolled from one end of the platform to the other, not glancing at me, perhaps not even seeing me. His step was firm but less regular than usual. Sometimes he would stop, cross his arms over his chest, and observe the sea. What could he be looking for over that immense expanse? By then the Nautilus lay hundreds of miles from the nearest coast!

The chief officer kept lifting his spyglass and stubbornly examining the horizon, walking up and down, stamping his foot, in his nervous agitation a sharp contrast to his superior.

But this mystery would inevitably be cleared up, and soon, because Captain Nemo gave orders to increase speed; at once the engine stepped up its drive power, setting the propeller in swifter rotation.

Just then the chief officer drew the captain's attention anew. The latter interrupted his strolling and aimed his spyglass at the point indicated. He observed it a good while. As for me, deeply puzzled, I went below to the lounge and brought back an excellent long-range telescope I habitually used. Leaning my elbows on the beacon housing, which jutted from the stern of the platform, I got set to scour that whole stretch of sky and sea.

But no sooner had I peered into the eyepiece than the instrument was snatched from my hands.

I spun around. Captain Nemo was standing before me, but I almost didn't recognize him. His facial features were transfigured. Gleaming with dark fire, his eyes had shrunk beneath his frowning brow. His teeth were half bared. His rigid body, clenched fists, and head drawn between his shoulders, all attested to a fierce hate breathing from every pore. He didn't move. My spyglass fell from his hand and rolled at his feet.

Had I accidentally caused these symptoms of anger? Did this incomprehensible individual think I had detected some secret forbidden to guests on the Nautilus?

No! I wasn't the subject of his hate because he wasn't even looking at me; his eyes stayed stubbornly focused on that inscrutable point of the horizon.

Finally Captain Nemo regained his self-control. His facial appearance, so profoundly changed, now resumed its usual calm. He addressed a few words to his chief officer in their strange language, then he turned to me:

"Professor Aronnax," he told me in a tone of some urgency, "I ask that you now honor one of the binding agreements between us."

"Which one, captain?"

"You and your companions must be placed in confinement until I see fit to set you free."

"You're in command," I answered, gaping at him. "But may I address a question to you?"

"You may not, sir."

After that, I stopped objecting and started obeying, since resistance was useless.

I went below to the cabin occupied by Ned Land and Conseil, and I informed them of the captain's decision.
