"Here! Stop that! Come back!"

The German paused, hesitated an instant, glanced at Nat rushing toward him, and leaped. But he was a second too late. The young pilot grabbed him around the legs, and held on like grim death.

"What are you doing?" Nat cried. "Don't you know you'll be swept right into the propeller and be cut to pieces!"

"Let me go! Let me go!" insisted the youth in a low, intense whisper, as though he was afraid of being heard.

"Not unless you promise not to jump."

"I vill not make promises! I haf no use for to live! I vant to end it all! Let me go!"

He tried to escape from Nat's hold, but the young pilot had no gentle grip, and his arms were strong.

"Let me go! Let me go!"

The German was pleading now.

"Not much!" panted Nat. "You can't commit suicide from this boat."
