"Lathrop," ordered Frank, "you and Billy take Mr. Barr back to shore. Harry and I will stay here.
"We have a lot to do. Leave the Golden Eagle ashore to be packed and forwarded later. Hurry back in the launch."
"What are you going to do?" demanded Barr.
"I think that your interest in our movements ceased with the signing of this paper," rejoined Frank.
At that moment the Brigand gave a violent shudder as if she was indeed about to go down. With a shrill scream of terror old Barr ran out on deck and hastily clambered down on to the reef. From there he waded with Billy and Lathrop to the Golden Eagle II, and was taken ashore.
"Now then to work," said Frank as the aeroplane winged her way shoreward with their enemy.
"What are you going to do?" demanded Harry in an astonished tone. There didn't seem to be much to do to his mind but wait till they were taken off the stranded yacht by the launch.
"You'll see," replied Frank. "In the first place, Harry, the Brigand was never in any danger of sinking. She is as sound as a dollar."
"Are you crazy?" cried Harry, "why there's a lot of water in her engine-room. She must have sprung a leak as big as a house."
Frank laughed.
