Suddenly he leaned farther forward and slapped his hand smartly on the pilot's shoulder. The latter nodded and turned the nose of the sky machine downward. This was Irving's cue. He leaned back and pulled the release lever as far as it would go.

CHAPTER XXII

BEHIND THE GERMAN LINES

The "escape" was successful in every respect. The boy rocked to and fro all the way down, like a cork on a billowy sea. Down, down he went, the scene continuing, in the glare of innumerable lights of the battle, almost as bright as day. Irving could see clearly where he was going, although it was just beyond the zone of blazing activities. Between the chosen landing place and the fighting terrain was a small belt of timber, but the surroundings were lighted so brilliantly that the general character and lay of the land could be determined even from a height of several thousand feet.

Reinforcements were being rushed forward from points farther in the rear. Irving could see a wave of men advancing toward the lighted area. It looked as if attempts were being made to retake the hill, or what was left of it. Undoubtedly the enemy had lost heavily as a result of the volcanic explosions and the need of reserves was pressing at the front.

Irving landed right in the midst of a company of advancing men. The lieutenant called a halt and remained long enough to make inquiry as to the meaning of the parachute descent. The boy replied in fairly good German that he was a spy in the service of the emperor, and asked to be directed to regimental, divisional or army headquarters. The officer assigned a sergeant to accompany the "arrival from the sky" and, after a tramp of more than an hour over a highway on which they had to dodge camions and autos and motorcycles and troops almost as watchfully as one must dodge heavy traffic in a warehouse district in a large city, they arrived at a small town where they found a brigadier general's headquarters in what had formerly been the chief municipal building of the place.

Lieutenant Ellis was taken in charge here by an intelligence attache, who, observing the Canadian uniform worn by the boy, questioned him as to his identity and mission. Irving was greatly pleased, as the conversation progressed, to find that he understood almost everything his inquisitor said and could answer intelligibly all the questions put to him. The conversation, freely translated into English, was as follows:

"Who are you?"

"My name is Hessenburg. I am a second lieutenant in the Canadian army. But I am a Prussian sympathizer and the bearer of a message from agents of Emperor William working secretly for him on the other side of the Atlantic ocean."

"To whom is the message addressed?"
