"I should say so!" shouted Earl. "A perfect hit!"

One at least of the four missiles dispatched had gone straight to its mark and had evidently struck directly in front of the locomotive. A great mass of sparks shot skyward and lighted up an appalling scene of destruction.

The engine had been derailed and had overturned. The remaining cars had piled up one on top of the other until the whole train lay in a tangled mass of wreckage alongside the track. The bombs had done their work to perfection.

"Now for home," cried Jacques, immediately directing the course of the monoplane higher and higher from the earth.

"Yes, I think we've done a night's work all right," said Leon.

"That bomb certainly landed in the right spot," exclaimed Earl warmly.

"What was on that train?" asked Leon.

"Munitions," said Jacques quickly. "Listen to that."

From below came the sound of heavy explosions and the flash of bursting shells could be distinctly seen.

"Is that the train?" demanded Earl in amazement.
