The night man slipped out in the dawn and called the day man who was the station master, explaining that the old man was at the station and evidently unhappy. The agent came on unusually early and endeavored to arrange for a light engine to carry the superintendent back to the Junction. At the end of three hours they had a freight engine that had left its train on a siding thirty miles away and rolled up to rescue the stranded superintendent. Now, every railway man knows that when one thing goes wrong on a railroad, two more mishaps are sure to follow; so, when the rescuing crew heard over the wire that the train they had left on a siding, having been butted by another train heading in, had started back down grade, spilled over at the lower switch, and blocked the main line, they began to expect something to happen at home. However, the driver had to go when the old man was in the cab and the G.M. with a whole army of engineers and workmen waiting for him at Pee-Wee; so he rattled over the switches and swung out on the main line like a man who was not afraid. Two miles up the road the light engine, screaming through a cut, encountered a flock of sheep, wallowed through them, left the track, and slammed the four men on board up against the side of the cut. Not a bone was broken, though all of them were sore shaken, the engineer being unconscious when picked up. "Go back and report," said the old man to the conductor. "You look after the engineer," to the fireman. "Will you flag west, sir?" asked the conductor. "Yes,--I'll flag into Pee-Wee," said the old man, limping down the line. To be sure, the superintendent was an intelligent man and not the least bit superstitious; but he couldn't help, as he limped along, connecting these disasters, remotely at least, with general order No. 13. In time the "unseen signal" came to be talked of by the officials as well as by train and enginemen. It came up finally at the annual convention of General Passenger Agents at Chicago and was discussed by the engineers at Atlanta, but was always ridiculed by the eastern element. "I helped build the U.P.," said a Buffalo man, "and I want to tell you high-liners you can't drink squirrel-whiskey at timber-line without seein' things nights." That ended the discussion. Probably no road in the country suffered from the evil effects of the mysterious signal as did the Inter-Mountain Air Line. The regular spotters failed to find out, and the management sent to Chicago for a real live detective who would not be predisposed to accept the "mystery" as such, but would do his utmost to find the cause of a phenomenon that was not only interrupting traffic but demoralizing the whole service.
