"Forward with you, Mr. Chadwick," cried Jack, "and see if you can't get better results there. The men seem to have lost their nerve."

Frank sprang forward. Jack's words were true. It appeared that the crew in the forward turret were so anxious to sink the first submarine that they had not taken time to find the range.

"Cease firing!" shouted Frank as he sprang into the turret.

The order was obeyed, but there came a grumble from the men at what they deemed such a strange command under the circumstances.

"I thought you fellows were gunners," said Frank angrily. "Smith, get the range."

Smith did so, and announced it a moment later.

"Now," said Frank, "get your aim, men."

No longer was there confusion in the forward turret. The guns were trained carefully.

"Ready," cried Frank. "Fire!"

"Crash!"
