Hand in hand, ship and breeze blew on; but the breeze came faster than the ship, and soon the Pequod began to rock.
By and by, through the glass the stranger’s boats and manned mast-heads proved her a whale-ship. But as she was so far to windward, and shooting by, apparently making a passage to some other ground, the Pequod could not hope to reach her. So the signal was set to see what response would be made.
Here be it said, that like the vessels of military marines, the ships of the American Whale Fleet have each a private signal; all which signals being collected in a book with the names of the respective vessels attached, every captain is provided with it. Thereby, the whale commanders are enabled to recognise each other upon the ocean, even at considerable distances and with no small facility.
