"True," was his commander's response, and a slight smile lighted, up
his own features.

He arose and extended his hand. Both lads shook it heartily.

"I hope," said General Pershing, "that you may both come through
safely. But if you don't -- well, good-bye. I don't need to tell you
that if one can get through with the list that, from the nation's
standpoint, what happens to the other is insignificant."

"I have a request to make, sir," said Hal, as they turned to go.

"Consider it granted," replied his commander.

"It is this," said Hal. "I believe that it would be well for us to
take a third man along. It may be that he will never reach the German
lines, but he should prove of help for the other two."

"Have you the man in mind?" asked General Pershing.

"Yes, sir. A man named McKenzie, a private in our troop. He's a
Canadian, and has seen years of active service. Also, as I happen to
know, he speaks German fluently."

"I shall give you a paper authorizing his indefinite leave of absence,"
said General Pershing.

He scribbled a few words on a piece of paper, and passed it to the
lad. The boys drew themselves to attention, saluted, and left.
