The man at the wheel did as the Battleship Boy had ordered him to.

"Now, slow down. Drift in."

A moment more and the life lines shot out, a half dozen wet and angry fishermen being hauled aboard the motor boat. The men were fighting angry.

Shaking the water from their clothes, they started for Dan with angry imprecations. Not only had they been upset, but they discovered that the truant torpedo was driving through their nets. Yells of rage from the fishermen in other boats told Dan that they, too, had discovered what was occurring.

On went the torpedo, ripping net after net. It seemed bent upon destruction, for, after passing through all the nets in its course, it turned almost squarely about and dived through the rest of the nets. Every net, with its burden of fish, was utterly destroyed.

Dan grabbed up a boat hook as he saw the rescued men meant business.

"Stand back!" he commanded. "I'll smash the first one of you who comes forward. Ahoy there, fishing boats. Come up here and take these men off, and no nonsense about it, either."

The men hesitated.

"Throw him overboard!" cried a more turbulent spirit.

"Try it, if you want to, men, but I warn you this is a government boat. If you commit an assault on board, or on one of its crew, you will be in for a long term in a federal prison. Think you want to take that chance?"
