"Yes, yes; I'm expectin' my darter on that train," answered the woman,
now as excited as our hero. "Hurry up! the train's due in fifteen
minutes."

Seizing the tablecloth, Harry gathered it quickly into a bundle and
ran back to the railroad. He hurried down the track west of a curve
which was a few hundred feet beyond the washout, and saw the train
coming at full speed. He jumped on a fence skirting the tracks, and
waved the tablecloth wildly.

"Will they see it?" he asked himself, anxiously.

It was an anxious moment for Harry as he stood waving the danger
signal, uncertain whether it would attract the attention of the
engineer. It did! The engineer, though not understanding the meaning
of the signal, not knowing indeed, but it might be a boy's freak,
prudently heeded it, and reversing the engine, stopped the train a
short distance of the place of danger.

"Thank God!" exclaimed Harry, breathing a deep sigh of relief.

The engineer alighted from the train, and when he looked ahead, needed
no explanation.

"My boy!" he said, with a shudder, "you have saved the train."

"I am glad of it, sir. My heart was in my mouth, lest you should not
see my signal."
