an tell you I have no
desire to get blood poisoning."

"No danger of that if you have it looked after soon enough."

"I suppose they think we're lost back at headquarters," said Leon.

"I wonder if they do," mused Earl. "We've been away quite a while,
haven't we?"

"It seems like months to me."

"The moon has set."

"Has it? I can't see anything from here. How about helping me back
into my seat?"

With a great deal of effort and not without some pain and a few groans
on the part of the battered young soldier he finally was able, with his
brother's help, to resume his proper place. The night wind blowing
full in his face was most refreshing and served to clear his head and
revive his tired brain.

"Are we still behind the German lines?" he inquired.

"Leon wants to know if we are still behind the German lines," Earl
shouted to Jacques.

"We are," said Jacques, "and if you'll look down below you'll see
something interesting. Up ahead there."

Both brothers peered eagerly down through the darkness and in the
direction Jacques had indicated. At first they saw nothing, not even a
light of any sort, but after a moment they discovered what it was that
their pilot had in mind.

Far below and some distance in front of them they saw something that at

"I couldn't make out what it is."

"It's a train all right and it is undoubtedly carrying either troops or
ammunition."

"To be used against our men?" exclaimed Earl. "If we could only stop
it."

"We can and we will."

"But how?"

"Haven't we bombs with us?"

Lower and lower Jacques guided the speeding monoplane. Nearer and ever
nearer they approached to the fast rushing train beneath them. It was
directly ahead of them now and the young French pilot dogged its course
closely.

"Get your bombs ready and make 'em sure," he directed. "I'm going down
pretty low and we won't be able to waste any time."

Underneath, the dark outline of the train could be faintly seen as it
glided along its steel track bringing its load of human or mechanical
food to the hungry battle-line. Swiftly but with great care the two
brothers made rea
