"Torpedo heading your way! Look out for her!" he shouted with hands to mouth. "Pull out, men; pull out for your lives!"

The fishermen looked at the Battleship Boy, standing poised on the plunging bow of the motor boat, wondering if he had gone crazy.

"Pull out, I tell you! There she comes!"

The motor boat was driving; ahead full speed.

"They'll be hit, sure as fate," groaned the boy. "They can't see her because they are so low in the water."

A yell from the fishermen told him that they had made sudden discovery of their peril. Dan, with his wig-wag flag, motioned to them to separate at a certain point. For a wonder they understood and laid to their oars in great haste.

All at once from the water right at the side of one of the fishing boats the torpedo emerged. It missed the boat by a matter of inches only, but the tail of the projectile hooked the keel. Like a flash the fishing boat turned over and the men were scrambling in the water.

"Drive in there, full speed!" commanded Dan.

"We'll get fouled in the fish nets."

"Never mind the nets. Those men may drown. Drive in there, I say!"
