"Thirty-seven long paces due north from the Witch's Head.' 'Eighty-nine long paces due east from The Three Sisters,'" he went on.
"Now we're getting down to something definite!" exclaimed Captain Hamilton.
"That's all," announced Drew. "What do you suppose it means?"
"It can mean only one thing, it seems to me," said Tyke excitedly. "It's pointing to the spot where the doubloons are buried."
"Yes," agreed the captain, "I should take it to mean that if you mark off thirty-seven long paces north from the Witch's Head and eighty-nine long paces east from The Three Sisters, the spot where those paths cross would be the place to dig."
"Do you see anything on the map that would give a hint as to the latitude and longitude?" asked Grimshaw anxiously.
"No," answered Drew. "Wait a minute though," he added hastily. "Here's something that looks like figures down in the lower left hand corner. Fifty-seven .... No! Sixty-seven-three is one, and thirteen-ten is the other."
"That can only stand for longitude and latitude!" cried Tyke. "Quick, Allen, git down that Hydrographic Office chart. That'll cover it."
