I followed Captain Nemo. The hatch closed, the ballast tanks filled with water, and the submersible sank some ten meters down.
Just as I was about to repair to my stateroom, the captain stopped me.
“Professor,” he said to me, “would you like to go with me to the wheelhouse?”
“I was afraid to ask,” I replied.
“Come along, then. This way, you’ll learn the full story about this combination underwater and underground navigating.”
Captain Nemo led me to the central companionway. In midstair he opened a door, went along the upper gangways, and arrived at the wheelhouse, which, as you know, stands at one end of the platform.
It was a cabin measuring six feet square and closely resembling those occupied by the helmsmen of steamboats on the Mississippi or Hudson rivers. In the center stood an upright wheel geared to rudder cables running to the Nautilus’s stern. Set in the cabin’s walls were four deadlights, windows of biconvex glass that enabled the man at the helm to see in every direction.
The cabin was dark; but my eyes soon grew accustomed to its darkness and I saw the pilot, a muscular man whose hands rested on the pegs of the wheel. Outside, the sea was brightly lit by the beacon shining behind the cabin at the other end of the platform.
“Now,” Captain Nemo said, “let’s look for our passageway.”
Electric wires linked the pilothouse with the engine room, and from this cabin the captain could simultaneously signal heading and speed to his Nautilus. He pressed a metal button and at once the propeller slowed down significantly.
