"I say," broke out Fogg finally, slamming down into his seat. "It's about time for something to happen, Fairbanks." "Think so?" queried Ralph lightly. "Been pretty smooth sailing lately, you see." "That's the way it ought to be in a well-regulated family, isn't it, Mr. Fogg?" "Humph--maybe. All the same, I'm an old bird and know the signs." "What signs are you talking about, Mr. Fogg?" "Our machine balked this morning when she took the turntable, didn't she?" "That was because the wiper was half asleep." "Thirteen blew out a cylinder head as we passed her--13, an unlucky number, see?" "That's an every-day occurrence since the high pressure system came in." "White cow crossed the track just back a bit." "Nonsense," railed Ralph. "I thought you'd got rid of all those old superstitions since your promotion to the best job on the road." "That's it, that's just it," declared the fireman with serious vehemence--"and I don't want to lose it. Just as I say, since we knocked out the sorehead crew of strikers and made the big record on that famous snowstorm run on the Mountain Division, we've been like ducks in clear water, smooth sailing and the best on earth none too good for us. It isn't natural. Why, old John Griscom, thirty years at the furnace, used to get scared to death if he ran two weeks without a broken driving wheel or a derail." "Well, you see we're on a new order of things, Mr. Fogg," suggested Ralph brightly. "They've put us at the top-notch with a top-notch machine and a top-notch crew. We must stay there, and we'll do it if we keep our heads clear, eyes open and attend strictly to business." The fireman shook his head fretfully and looked unconvinced. Ralph knew his stubborn ways and said nothing. The young engineer of the Overland Express was in the heyday of satisfaction and contentment. He was proud of his present position, and was prouder still because he felt that he had earned it through sheer energy and merit. As Fogg had declared, the appearance of the three men noted had something sinister about it, but the fireman was always getting rattled about something or other, fussy as an old woman when the locomotive was balky. Ralph insisted upon enjoying to the limit the full measure of prosperity that had come to him. Both had fought hard to secure the positions they now held, however, and the mere hint of a break in the pleasant programme set them up in arms instanter. They had chummed together and had learned to love the staunch, magnificent locomotive that pulled the Overland Express as if it was a fellow comrade, and would have had a pitched battle any time with the meddler or enemy who plotted injury to the prize train of the Great Northern.
