"It looks as though all the Germans had gone back to Berlin," remarked Frank in an undertone.

"Does it?" said the corporal grimly. "Give me your hat."

He took the hat that Frank extended and lifted it above the parapet on the point of a bayonet.

A week passed by with only two casualties on the American side, for the sector was indeed a quiet one. But certain signs of a projected movement on the part of the enemy had made the American officers uneasy, and one day Corporal Wilson called Frank apart.

"Sheldon," he said, "Captain Baker has ordered me to take a squad of men on the first dark or foggy night for patrol duty in No Man's Land. I want you, Raymond, Bradford and Waldon to go with me."

"Good," said Frank, promptly. "We'll be ready."

He sought out his comrades and eagerly imparted the information. They received it with delight.
