From the seamen there came a hoarse cheer.

“It’s a battleship! She’s signaling!” shouted Jack in a voice that shook. “It’s Morse!”

He took a long breath or two. Then he choked out the message that was flung on the sky.

“Courage! We are coming!”

And then pandemonium broke loose. Under the glaring sky, seamen danced and shouted and the other members of the party shook hands. Only Jarrold stood silent and aloof, looking at his niece and De Garros. It was as if he knew that his hold over her was broken forever, and that the approaching warships, speeding to the rescue, meant for him shackles and iron bars.

The scene shifts to Colon harbor. Into port are steaming the Birmingham, scout cruiser, and the Wasp, torpedo destroyer, the craft that rescued the castaways of Castle Island. Already by wireless the story of the lost liner and the wonderful resourcefulness of Jack Ready and Sam Smalley has gone out to the world. Big crowds are waiting to meet the rescuing warships. Among them are the military attachés to whom Colonel Minturn, thanks to Jack, will be able to hand the Panama documents so nearly lost forever.

At the stern of the Wasp, under the ensign, are standing Jarrold’s niece and De Garros. He is telling her that Colonel Minturn has promised to intercede for her uncle, and that in all probability he will be deported with a warning never to tread American soil again, in place of being imprisoned. Nations do not care to advertise their troubles with international spies, if it can be avoided.

Jack and Sam, on board the Birmingham, stand happily by the wireless operator of the cruiser. He is taking a message. Presently he turns to them.

“Some news that will interest you, fellows,” he says. “All the boats from the Tropic Queen have been picked up, without the loss of a single passenger.”

“Good work!” exclaim the two listeners heartily.
