Captain Nemo came to the surface to take observations on our location. I looked at the sea, near the Japanese coast, one last time before returning into the submarine.

And now, sir, I must attend to the Nautilus and my crew, so I must leave you, said the captain. We are currently twenty-six fathoms below the surface of the ocean. Here are maps of the oceans of the the world. And now, I must go.

For the next hour, I could think of nothing but what captain had told me that morning. I began examining one of the sea maps, showing the various sea rivers of the earth. The sea has large rivers, just as the continents do. These waters are known for their direction, temperature, and color. There are five main sea revers of the earth: one in the North Atlantic, a second in the South Atlantic, a third in the North Pacific, a fourth in the South Pacific, and a fifth in the Southern Indian Ocean.
