“Why, it’s all right—we’re in pursuit of the enemy,” replied Frank. “Just because our private interests happen to be served also, doesn’t do any harm.”

“I think you’re right,” agreed Mr. Kennedy. “I will explain matters if you get into any trouble. But, boys, I really think we are gaining on them!”

Ned and Frank stood up, and looked searchingly ahead. They were nearer to the boat containing Bernardo and his cronies. They could see them more plainly. There appeared to be some dispute going on about the tin box, which was wound around with many turns of rope.

“I wish they’d have such a difference of opinion that they’d fight among themselves,” remarked Ned. “Then some of them might come over on our side, and we’d have the evidence we need.”

“No such luck,” sighed Frank. “We might as well wish they’d go near enough the battleship, so we could signal to have them fired on.

“Not sunk, though,” he added quickly, “for that would lose the box for us altogether. I’d just like to have one of our quick-firers disable them. But we’re going away from the Georgetown, instead of toward it.”

This was only too evident.

Of course Ned and Frank might have fired on the escaping men in the boat ahead of them, as they were within rifle shot, but neither of the boys dreamed of shooting at the rascals. It was too cold-blooded.

The boat of the fruit dealer was making good time. It was smaller and lighter than the larger craft containing Bernardo and the others, and was not so heavily laden.

“Ned, I believe we’re going to catch them!” Frank cried, a little later. “I can see them ever so much more plainly.”
