Madden moved over to it eagerly, hoping this pin would give him some inkling as to where the disaster, if there had been one, occurred. He noted the latitude and longitude indicated by the marker, then turned excitedly to Greer.
"Look here!" he cried, "this pin marks our position at this moment. We are right here!" he touched the point on the map.
"How do you know it does?"
"I calculated the dock's position this morning."
"Well, what of that? She will probably lie here till she rots in this stagnant sea."
"That's the point: This is not a stagnant sea. There is a current of about six miles a day in the Sargasso, very slow, but it will change a ship's reckoning."
