"I was," answered Ralph Fairbanks. "I have been promoted."
"Where to?"
"Here."
"What!" flared out Mort. "What do you know about switch-tower duty?"
"Not much, only what Mr. Knight has shown me for the past two days. But I'll catch on, I guess."
Mort Bemis struck a tragic pose and his voice quavered.
"Oho! that's the game, eh? All cut and dried! My bread and butter taken away from me, to give to one of the master mechanic's pets. Augh!"
Mort retreated with a grimace of disgust. He was standing under a floor grating. Purposely or by accident, Knight, overhead, had dropped a dipperful of water through the grating.
Mort jumped outside the lower tower room, growling like a mad catamount. He shook his fist menacingly at Ralph.
"Fairbanks," he cried, "I'll fix you for this!"
Ralph did not even look at his enemy again. He completed his ascent of the ladder, and came up through the trap with a bright, cheery hail to old Jack, whom he liked and who liked him.
"I report for active duty, Mr. Knight," he announced briskly.
