"Could it be possible——" he exclaimed, and stopped short.

Jack looked at him in a questioning way.

"Could what be possible, sir?" he asked.

"Why, that Judson and the others are on board that black craft?"

"Ginger! That never occurred to me!" cried Jack; "and yet, if they were following us to find out where you are located that would be just the sort of way in which they would behave."

"So I was thinking," said Captain Simms thoughtfully. "However, we can soon find out."

He opened a locker and took out his binoculars. Then he focused them on the black craft.

"Well?" questioned Jack, as the captain laid them down again.

"There's a man at the wheel, but he isn't the least like your descriptions of your men," said the captain.

"What does he look like?" questioned Billy.
