could pass muster on almost any other subject and was well posted on current events.

Jack’s father had been taken suddenly ill and after a protracted sickness died. Jack took charge of the store. One day a ship put into the harbor and several sailors landed, went to the store and procured provisions. In Jack’s absence, they departed without making payment.

Jack returned a little while later, and when he learned what had occurred, he put off in a small boat after the ship, which he reached before she could get under way.

Now Jack, though young in years, was a stalwart lad. He stood above six feet, and was built proportionately. The sailors laughed at him when he demanded payment and a struggle followed. By exerting his powerful strength and some resourcefulness, Jack succeeded in overcoming the crew.

It was then that he learned there were two prisoners aboard the ship. These he released. They proved to be Frank Chadwick and a British secret diplomatic agent.

Frank, who had been in Germany when the great European war broke out, had become separated from his father after getting over the border into Italy. In Naples one night he had gone to the aid of a sailor on the water front and saved him from injury at the hands of three others.

The sailor whom Frank had rescued showed a queer sense of gratitude by having him shanghaied aboard a small schooner. Here, under the stern rule of an American skipper, he had become one of the crew. The crew mutinied, killed the captain, and, binding Frank securely, threw him below with the other prisoner, the diplomatic agent.

Jack’s unexpected appearance upon the scene was indeed a welcome sight to both. Upon learning the nature of the work upon which the secret agent was bound, the two lads had volunteered to help him out. This offer was accepted, and thus both found themselves principal figures in a diplomatic coup that broke up the Triple Alliance and took the support of Italy away from Germany and Austria.

It was while with the secret agent that they had met Lord Hastings, and it was through the good offices of the latter that they finally found themselves attached to the British fleet as midshipmen. Lord Hastings had taken an instant liking to the lads and had them attached to his ship. Later they had been commissioned lieutenants.

Jack and Frank had seen considerable fighting. It was through their strategy that the British had won their first sea victory, off the coast of Heligoland, when four of Germany’s most powerful sea fighters had been sent to the bottom. They had saved the British fleet from possible annihilation by being fortunate to discover a spy.

The two lads, since the war began, had seen service in many waters. They had been on patrol duty off the west coast of Africa; they had served under the French flag when, under the tricolor, they had delivered a severe blow to the Austrian fleet in the Adriatic; they had trailed the German cruiser Emden, nicknamed the “terror of the sea,” through the Indian ocean, and had been present when she was finally sunk by the Australian cruiser Sydney; they had taken part in sinking the German fleet in the South Atlantic, off the Falkland islands; they had been aboard a British submarine that sank three Turkish cruisers in the Persian Gulf; they had seen the capture of the German fortress of Tsing-Tau, in China, by allied British and Japanese troops, and finally they had been instrumental, while in London, of exposing a plot that would have been a severe blow to Great Britain, and of capturing a second German spy and a British traitor, who stood high in the regard of Winston Spencer Churchill, first lord of the Admiralty.

Three times the ships to which they were attached had been sunk, and they had had many narrow escapes. Once Lord Hastings had gone down with their vessel, and the lads had believed
