We heard a click as the safety catch on the man's rifle lock was thrown off and the weapon made ready to discharge. The Major was watching the nervous hand that rested none too steadily on the trigger stop. He stepped to one side, but the muzzle of the gun followed him.

"Huh-huh-huh-halt! I tuh-tuh-tell you."

This time the whisper vibrated with nervous tension and there was no mistaking the state of mind of the sentry.

"Take it easy," replied the Major with attempted calm. "I'm waiting for you to challenge me. Don't get excited. This is the commanding officer."

"What's the countersign?" came from the voice in a hard strain.

"Troy," the Major said, and the word seemed to bring worlds of reassurance to the rifleman, who sighed with relief, but forgot to move his rifle until the Major said:

"Will you please take that gun off me and put the safety back in?"

The nervous sentry moved the gun six inches to the right and we correspondents, standing in back of the Major, looked into something that seemed as big as the La Salle street tunnel. I jumped out of range behind the Major. Eyre plunged knee-deep into water out of range, and Woods with the rubber boots started to go over the top.

The click of the replaced safety lock sounded unusually like the snap of a trigger, but no report followed and three hearts resumed their beating.

"There is no occasion to get excited," the Major said to the young soldier in a fatherly tone. "I'm glad to see you are wide-awake and on the job. Don't feel any fears for your job and just remember that with that gun and bayonet in your hands you are better than any man who turns that trench corner or crosses out there. You've got the advantage of him, and besides that you are a better man than he is."
