“Start up the engine again and keep it going full speed!” was the first order the new skipper gave the pilot.

Presently the boat began to pick up, as the propeller churned the water. It felt good to Amos, standing there and listening to the terrific pounding on the lower side of the hatch. He took off his hat and waved it about his head as he gave a loud, boyish hurrah that came from the depths of his heart.

No doubt that organ was pounding against his ribs with the furious energy of a trip-hammer; but apparently the danger point had been safely passed, and they had a free course open before them.

The three men who jumped overboard had meanwhile managed to reach shallow water. They were standing, up to their waists in the sea, at what they considered a safe distance from the powerboat, staring at the now moving craft as though unable to believe their eyes.

The smoke had ceased coming up from the hold as soon as the hatch was clapped on, and, with the starting of the engine, the boat showed signs of leaving the unfortunate trio in the lurch—at least they must have considered themselves in a bad box at the time, though later developments proved that they were exceedingly fortunate.

Loud rang out their shouts as they made all sorts of wild gestures, imploring their companions not to desert them. Perhaps the simple fellows, not aware of the dramatic acts that were taking place aboard the boat, imagined the skipper meant to discipline them for deserting when there was need of their services.

Amos waved his hand hilariously toward the three. He was feeling in a merry mood. The bright scheme which Jack originated had turned out so successful!

One look gave Jack his course, and he impressed it upon the pilot.

“We want to head straight as an arrow for the Dardanelles,” he said sternly. “You will be all right as long as you behave, but the first sign of treachery and it means your end. Our lives are at stake now and we will shoot you down like a dog if you turn on us. We want to run across some warship of the Allies, to whom this boat and its cargo can be surrendered. And if you behave we will guarantee that you are let go free. Get that?”

The man had listened intently, watching every gesture made by Jack. At the conclusion of the short harangue he nodded his head and even allowed a grim smile to flit athwart his dark face. Being a daring chap himself he could admire an exhibition of American pluck such as the two boys were displaying. Anyone who managed to get the better of a sly old sea-dog like Captain Zenos must be pretty wide-awake, according to his opinion.
