Read it through once

Darkness came on; but three lights up and down in the Pequod’s main-rigging dimly guided our way; till drawing nearer we saw Ahab dropping one of several more lanterns over the bulwarks. Vacantly eyeing the heaving whale for a moment, he issued the usual orders for securing it for the night, and then handing his lantern to a seaman, went his way into the cabin, and did not come forward again until morning.
