"Just the three of us?" demanded Earl.

"Why, yes," replied Dubois. "You will remember that there has been no firing from that spot all day. It is probably empty."

"Do you think we can reach it?" exclaimed Leon eagerly.

"Why not? It is very close and yet we'll not be fired upon by the Boches. If we remain here it is but a question of time before we are entirely wiped out. What do you say?"

"I say to go," replied Leon at once.

"And I too," echoed Earl.

"Come then," urged Dubois and without waiting another moment he crawled up out of the crater and started across the space intervening between them and the German trench. One on each side, Leon and Earl accompanied him.

These two boys were typical twins in every respect. Strangers could hardly ever tell them apart and even their intimate friends became confused at times. They looked alike, their voices were alike, and they even seemed to think alike. The only distinguishing mark was a small mole under Earl's right eye.

"Don't let any German clip that mole off, Earl," warned Dubois. "If that should happen I don't know how we could ever tell which was which."

"It's impossible to see anything to-night anyway," said Leon. "I have never seen such blackness."
