Silk dropped the extinguished match and carefully trod it under foot. Experienced prairie rider as he was, he was always cautious about fire.

"You've got to allow something for my being in uniform," he smiled. "Law-breakers out here have a wholesome dread of the Mounted Police."

Touching the wide brim of his hat with a forefinger, he turned away, striding along the platform with a military clink of spurs.

He went towards the front of the waiting train, where the engine had just been coupled and was being oiled up for the run along the branch line from Macleod to Crow's Nest Pass. The district superintendent stood by and was reprimanding the engine-driver, who had evidently been making some complaint about his job.

"What's the matter with you that you register for rest?" the superintendent wanted to know. "You know we're short handed, Ted Chennell bein' killed. You've got ter take Ted's place. You've only been at work twenty hours. There's Tom Morden has been on his engine twenty-eight hours, and Tom ain't askin' for rest yet. Say, some of you fellows ought to get a job clerkin' in a drug store. This yer train's got to go. You're the only available man to take her, and that's straight."

Sergeant Silk puffed for a few moments at his cigar before speaking.

"Seems to me, Mr. Garside," he remarked casually, "that Halkett and his engine are about on a par. They're both promising candidates for hospital."

The superintendent looked round at him in surprise, resenting his interference.
