"If you only kept your ignorance as well as your knowledge to yourself, Wharton, you'd have a greater reputation for wisdom. Look out!"

A shell that failed to explode in the air struck near. Carstairs threw himself upon Wharton, and, at the imminent risk of his own life, dragged him down just in time, as the shell burst and threw fragments over their heads.

"Thanks, Carstairs," said Wharton. "Your first name is Percy, but you don't act like a Percy."

"Expect the same from you, old fellow, when the time comes."

"I'll do my best."

John was absorbed now in the tremendous panorama of war, carried on with all the mighty machines of death that man had invented. A heavy German force appeared on their left also. It was yet distant, but it was nearer than the great mass in the center. Untrained as he was he knew nevertheless that the Germans, with their greatly superior numbers, were seeking to envelop the French. But the defensive guns on the right in the wood were maintaining a swift and terrible fire. They were pouring showers of shrapnel not only on the Uhlans, but upon the gray masses of infantry crossed the wide intervening fields.

The Strangers were now drawn up by one of the earthworks, but it would be a long time before they went into action. That heaving gray sea of Germans could not come within range of the rifles for an hour yet. Meantime the artillery would carry on the battle over a space of miles. While he waited he could look on and see it all.

More and more guns were coming into action. Batteries were sent off to the left to meet the second German flanking force there, and soon the heaviest of the French cannon in the center were able to reach the advancing enemy directly in their front.

The scene became tremendous and full of awe. There was little smoke, but along two vast semi-circles, one convex, and the other concave, flashes ran like continuous lightning, while the whole earth grumbled and roared. The air seemed surcharged with death, and John suddenly found it hot in his lungs as he breathed.

Through the roar of the guns he heard all the time the malicious shrieking of the shrapnel. It was falling among the defenders, killing and wounding hundreds, and John knew that the storm beat also on the great gray circle that was ever coming nearer. Now and then a crash, louder than all the rest, came from the forty-two centimeter, and whenever the shell struck true it tore everything about it to pieces, no matter how strong.
