rt distance away.

"What is it?" asked Stubbs in a hoarse whisper.

"Looks to me like a place where ammunition might be stored," said Hal,
quietly. "I shall have a look."

"Let it alone, Hal," said Stubbs, anxiously. "Don't go fooling around
there. You're likely to blow us all up."

"I guess not," returned Hal, "but I wouldn't mind blowing all the
ammunition up that the place may contain."

"By Jove!" said Chester. "A good idea! I'm with you."

"Well, I'm not," declared Stubbs. "I know where our aeroplane is and
that's where I'm going right this minute. I don't know how to fly the
thing, and if you fellows go fooling around that ammunition depot I'll
probably have to hunt another pilot; but Anthony Stubbs is not going to
be blown up with his eyes open when he can help it."

"Better wait here, Stubbs," said Chester.

"Not me," returned the little man, decisively. "You'll find me at the
plane when you get there; or if you get there, I should say."

"But there is nothing sure that the building contains ammunition," said
Hal. "I just guessed at it, Stubbs. Come and have a look."

"Oh, it contains ammunition, all right."

"How do you know?" demanded Chester.

"Well, if it didn't you fellows wouldn't have spied it. You call it good
luck. I call it hard luck. I tell you that every time I go any place with
you I risk my neck. Sure the building contains ammunition! It was put
there for the sole purpose of having you blow it up. That's the way it
looks to me. But I can see all the fireworks I want to from a distance.
Good-bye."

"All right, Stubbs, if you are such a coward," said Chester,
somewhat nettled.

"I'd rather be a live coward than a dead fool," was Stubbs' reply.

He walked off.

"Come on, Chester," said Hal. "We'll have a look at this place."

He led the way close to the building. Going slowly and cautiously they
advanced to within a short distance of the building without being
observed, although they could see an occasional dark shape as it moved
about in front of the building.

"Guards there," said Hal, briefly.

"Sure," said Chester. "I believe you have guessed right. I am sure the
place is filled with ammunition. Now if we could just dispose of the
guards and place a time fuse--"

"It would be a hard blow to the Germans," Hal agreed. "We'll try it."

Still cautiously they approached. A guard arose from in front of the
building. He stretched his arms. Apparently he had been asleep. Then he
