"Who is the man with the iron mask?" asked Ralph innocently.

"The superintendent, of course. Ever see him? Well, they say he was born with a frown on his face, called down his father and mother when he was six months old, and spent ten years at a special actors' school where they learn the ebony glare, the tones that chill a fellow, and that grand stern air that makes a railroad employee shake in his boots when the superintendent passes by."

"Why, I have found him rather dignified, but a thoroughly just and genial gentleman," said Ralph.

"Thank you, Fairbanks!" interrupted a voice that made the two friends start, and the head of the superintendent of the Great Northern came up through the trap. "Quite a word-painter, Mr. Knight!" he continued, glancing at old Jack with a grim twinkle in his eye.

"Ah, overheard me, did you?" retorted Knight, never abashed at anything. "You didn't wait till I got through. I was going to add, for the benefit of our young friend here, that all the qualities I was describing have made you the most consistent, thoroughgoing railroader in the country, that back of the mask were more pensions to deserving disabled employees than the law allowed, and a justice and respect for loyal subordinates that made you an honorary member of our union, and the Great Northern the finest railway system ever perfected."

"Thank you, Mr. Knight!" retorted the superintendent, a genuine flush of pleasure on his face. "I know you are sincere, so you will join me, I am certain, in telling our young friend that the risk he took to save the special this day entitled him to a high place in the esteem of his employers and associates."

"Right you are, sir!" answered Knight emphatically. "I'm proud of Ralph Fairbanks--and so are you."

[CHAPTER XIII--SQUARING THINGS]

Ralph was tremendously pleased at the praise of the superintendent of the Great Northern. He started for home, his work through with for the day, feeling that life was very much worth living.

He lost no time on this especial occasion in reaching the home cottage. He wanted to share his pleasure with his devoted mother.
