“Hold on, there,” spoke Bartley in a gruff tone, as the train got ready to start out. “I’ve got some personal property in that cab.”

“Bag of apples for a mate down the line,” mumbled the engineer, reaching under the seat. “Bag of--thunder! they’ve gone.”

The conductor had run to the caboose. The engineer drew back from the empty void under the seat in a puzzled, baffled way. Ralph beckoned to the operator.

“Watch that man,” he ordered in a quick whisper. “If he tries to send any messages ahead advise the operator to report instantly to headquarters.”

“What’s up--something?” declared the fireman of the special as the train cleared the yards at Portland.

“Yes,” replied Ralph, watching out for signals and testing gauges and airbrakes. “This is up: What kind of a man is your engineer, Bartley?”

“He’s not my engineer at all,” retorted the fireman rather testily, “and I was sorry when I was listed with him. He’s a bossing, quarrelsome sort of a fellow. He don’t train with my crowd, and I’m glad you’re on in his place. You’re Fairbanks, eh? Well, I’ve heard of you.”
