“Who is it?” demanded Mr. Schofield, who had listened to this interchange with strained attention.

“It’s Jim Anderson,” Allan explained. “He lives in that house right by the track about a mile west of here. He and I rigged up a private line—Mr. Mickey let us use that old wire. Perhaps he’ll be in time.”

“Perhaps—perhaps,” agreed the trainmaster; but he did not permit himself to hope. The chance was too slender. How was the boy to flag the train? How could he make the engineer see him through that driving snow? It was absurd to suppose it could be done.

“I think we’d better order out the wrecking-train,” he said, to the chief-dispatcher. “Call up a couple of doctors, too; we’ll probably need them; and tell the hospital to have its ambulance at the station here before we get back. As for that fool who made the mistake—”

He stopped abruptly. For, in the driving snow, the mistake was not so surprising, after all—the flyer was running ten minutes late, and the freight had come in exactly on her time—two facts with which the crew of the extra west could not have been familiar.

“Perhaps he’s paid for it with his life by now,” added the trainmaster, after a moment, and started toward the telephone to order the wrecking-train got ready.

Then, suddenly, he stopped, rigid with expectancy, for the instrument on the table in front of Allan had begun to sound.

“A—A,” it called. “A—A.”

“Tick-tick, tick-tick,” Allan answered, instantly.
