fact that it was traveling very slowly, both boys probably would have
been carried over the embankment to certain death; for it is doubtful
that either, in the darkness, would have noticed the absence of the
bridge in time to leap to safety.

And now Hal could make out a number of rapidly moving figures. To his
dismay, he saw that they were moving in his direction. He turned
quickly and ran back to the locomotive, where Chester was anxiously
awaiting his return.

"Out here, quick!" he cried, and Chester, in response to his command,
leaped to the ground.

Hal once more jumped aboard the locomotive, unheeding Chester's cry of
wonder, released the brakes, and threw the throttle wide open. Then he
dropped sprawling to the ground, while the engine dashed madly down
the track.

Hal was not badly hurt and was quickly on his feet.

"What's the matter?" asked Chester in alarm.

"Matter is that the Germans are coming this way," answered Hal. "Come,
let's get away from here while we have a chance. We may be able to escape
in the darkness."

"But why did you start that engine down the track like that?"

"Well, I couldn't see that it was any use to us any longer, and it may
dispose of a few more Germans. They are walking up the track in force."
