"Those men will bear watching--they are up to some mischief, Fairbanks." "I thought so myself, Mr. Fogg. I have been watching them for some time." "I thought you would notice them--you generally do notice things." The speaker with these words bestowed a glance of genuine pride and approbation upon his companion, Ralph Fairbanks. They were a great pair, these two, a friendly, loyal pair, the grizzled old veteran fireman, Lemuel Fogg, and the clear-eyed, steady-handed young fellow who had risen from roundhouse wiper to switchtower service, then to fireman, then to engineer, and who now pulled the lever on the crack racer of the Great Northern Railroad, the Overland express.
