Off about a mile lay the town, only a few lights showing. Ned wondered how many Americans were there, and if they were in any danger. He wondered, too, just how and where his own and his brother’s fortunes were invested, and what the chances were for recovering them. It was very still and quiet, save for the occasional footfall of some of the other sentries, or the little talk that went on as the guards were changed.

Ned was beginning to get sleepy again, in spite of the fact that he walked to and fro. His gun was feeling heavy. He wondered, after all, if there was any need of all this precaution.

Suddenly he thought he heard, in the water just below him, a slight commotion. At once his heart began to beat violently. Suppose it should prove to be a submarine after all. Or an automatic torpedo, which would presently burst and send them to the bottom. How had it gotten so near without his having heard or seen it? And there was, all about the Georgetown, a torpedo net, let down over the side to prevent the deadly missiles from hitting the ship’s plates!

Ned leaned over. Yes, something was moving in the water. He brought his rifle to bear, and was about to fire and give the alarm, when a searchlight was suddenly turned full on the very spot where there was a ripple in the calm surface of the sea.

Then there came a swish, and a flurry, and in the gleam of the powerful light Ned saw that it was a school of fish which had probably gathered near the battleship to feed on the scraps the cooks tossed overboard.

“Ha! That’s a good one on me!” Ned mused. “I’m glad I didn’t give any alarm.”

The sentry in charge of the searchlight said he had also heard the commotion in the water, and that was why he switched on the light. Of course the officer in charge of the sentries saw the light and had to be told why it was turned on. But there the incident ended.

“Shore leave will be granted!” was the unexpected order that was issued next day, the night having passed without accident.

“Hurrah!” cried Frank.

“Great!” echoed Ned. “Now we’ll have a chance to see what this country looks like, and we may find out something about the missing fortunes.”
