On Monday, August 8th, 1838, the large bark Ocean Ranger, of which I was second mate, was in latitude 38° 40′ N., and longitude 11° W. The hour was four o’clock in the afternoon. I had come on deck to relieve the chief officer, who had had charge of the ship since twelve. It was a very heavy day—a sullen sky of gray vapor seeming to overhang our mastheads within pistol-shot of the trucks. From time to time there had stolen from the far reaches of the ocean a note as of the groaning of a tempest, but there had been no lightning; the wind hung a steady breeze out of the east, and the ship, with slanting masts and rounded breasts of canvas, showing with a glare of snow against the dark ground of the sky, pushed quietly through the water that floated in a light swell to the yellow line of her sheathing.
