The boy, however, was too excited—too absorbed in the contemplation of the singular scene below him, and, at the same time, so occupied in handling his plane that he did not feel any tingling sensation of fear.

The battle-ground was covered with a thin veil of purplish smoke, and where the delicate shadows lay thickest on the earth he could occasionally distinguish the flashing lights of the guns or of exploding shells. But it all seemed very distant—very remote. The clouds of smoke from the bursting projectiles and innumerable batteries were but tiny spots amid the surrounding haze. Don realized that a vigorous bombardment from both sides was going on and that a devastating hail of missiles was creating havoc and destruction in the opposing trenches and far to their rear. Then he had a swift glimpse of that irregular brownish stretch of land running between the hostile forces—“No Man’s Land,” the most sinister, the most barren, the most mutilated strip of earth that has ever existed since the world began.

The patrol leader was now mounting higher, and the reason became almost instantly apparent. The air straight ahead had become filled with round puffs of viciously-spurting black smoke. The “Archies” were according the early morning visitors their usual warm reception.

A second more, and not so many yards away there suddenly appeared the largest and wickedest-looking puff of all, and, above the roar of the motor, the startled Don Hale could hear the explosion of the shrapnel shell launched by the German gunners.

The next instant he felt a terrifying thrill. His airplane was falling through space.

Almost stifled by the air rushing past, with a horrifying vision of impending catastrophe, the boy, nevertheless, managed to keep his wits about him. But escape seemed impossible. A perfect hail of “Archies” popped up in the air to the rear, to the side and to the front of the falling machine, the control of which he was desperately trying to regain.

Though his agony of suspense seemed long drawn out it was but a moment when the terrifying descent was over and the machine again flying parallel to the earth.

It was almost miraculous that it had not been riddled with the fragments of the bursting shrapnel shells. The din of their almost continuous explosions was ringing in the aviator’s ears, and in the violently-disturbed air the Nieuport was rocking and plunging like a boat in a heavy sea.

“Never fly in a straight line” was the advice which had been given to Don before setting out on the expedition, and after the first few moments of suspense had passed Don Hale managed to sufficiently calm his jumping nerves and follow this instruction. He turned the nose of his machine upward, and, in a zigzagging flight, shot like a rocket into the blue depths above.

A little later he found an infinite relief in seeing the black thunderbolts exploding hundreds of yards below.
