Although the boys discussed the matter thoroughly they could not decide where the call could have been sent from and finally again composed themselves for sleep, after extinguishing all but the riding or anchor light gleaming at the head of their signal staff.

Morning was just breaking when they were again aroused. This time a tap at a window brought Rowdy to attention and made Jack spring to his feet in alarm. In a boat sat Doright, the negro.

"What do you want?" demanded Jack. "Can we do anything for you?"

"No sir, Boss, youall caint do nothin' for me," answered the negro, rolling his eyes upward. "Mebbe youall kin do something for them pardners of yourn! They done gone away."

"Gone away!" gasped Frank, now joining Jack. "Gone away!"

"Yaas, sir, Boss, dey done goned away on a ship named the 'Walkfast.' I done holp Mister Pete put 'em on board."

"Where is this ship now?" demanded Frank crisply.

"She done lef' a hour or two ago," answered the negro. "If youall wants to know where she gwine, go ax de man at de custom house."

"That's a sensible thing to do," declared Jack. "Take this fellow aboard, while I go up to the custom house and find where the ship Walkfast was bound for and if this chap is not lying, we'll take a little cruise for an appetizer. Don't let him get away."

In a few minutes Jack came running back breathless. He made haste to get aboard, signaling for the boys to hoist the anchor.
