“They is a man here, who I don’t know, but who is asking all about you. He asked me many questions, and has talk with your uncle. He may mean good or he may mean bad, I don’t know which. If I find out ennything more I will let you know.

Yours respectful,

Dan.”

Rod puzzled over this note a good deal, and wondered who on earth could be making inquiries about him. If he had known that it was Brown the railroad detective, he would have wondered still more. He finally decided that, as he was not conscious of having done anything wrong, he had no cause for worry. So he dismissed the affair, and devoted his whole attention to learning to be a fireman.

Most people imagine it to be a very simple matter to shovel coal into a locomotive furnace, and so it is; but this is only a small part of a fireman’s responsibility. He must know when to begin shovelling coal, and when to stop; when to open the blower and when to shut it off; when to keep the furnace door closed, and when to open it; how to regulate the dampers; when and how to admit water to the boiler; when to pour oil into the lubricating cups of the cylinder valves and a dozen other places; when to ring the bell, and when and how to do a multitude of other things, every one of which is important. He must keep a constant watch of the steam-gauge, and see that its pointer does not fall below a certain mark. The water-gauge also comes in for a share of his attention. Above all, he must learn, as quickly as possible, how to start, stop, and reverse the engine, and how to apply, or throw off the air brakes, so that he can readily do any of these things in an emergency, if his engineman happens to be absent.

In acquiring all this information, and at the same time attending to his back-breaking work of shovelling coal, Rod found himself so fully and happily occupied that he could spare but few thoughts to the stranger who was inquiring about him in Euston. After a few days of life in the cab of locomotive number 10, he became so accustomed to dashing through tunnels amid a blackness so intense that he could not see a foot beyond the cab windows, to whirling around sharp curves, to rattling over slender trestles a hundred feet or more up in the air, and to rushing with undiminished speed through the darkness of storm-swept nights, when the head-lights seemed of little more value than a tallow candle, that he ceased to think of the innumerable dangers connected with his position as completely as though they had not existed.

There came a day, however, when they were recalled to his mind in a startling manner. It was late in the fall, and for a week there had been a steady down-pour of rain that filled the streams to overflowing, and soaked the earth until it seemed like a vast sponge. It made busy work for the section gangs, who had their hands more than full with landslides, undermined culverts, and overflowing ditches, and it caused enginemen to strain their eyes along the lines of wet track, with an unusual carefulness. At length the week of rain ended with a storm of terrific violence, accompanied by crashing thunder and vivid lightnings. While this storm was at its height, locomotive number 10, drawing a heavy freight, pulled in on the siding of a station to wait for the passing of a passenger special, and a regular express.

Truman Stump sat on his side of the cab, calmly smoking a short, black pipe; and his fireman stood at the other side, looking out at the storm as the special, consisting of a locomotive and two cars, rushed by without stopping. As it was passing, a ball of fire, accompanied by a rending crash of thunder, illumined the whole scene with an awful, blinding glare. For an instant Rod saw a white face pressed against one of the rear windows of the flying train. He was almost certain that it was the face of Eltje Vanderveer.

A moment later the telegraph operator of that station came running toward them, bareheaded, and coatless, through the pitiless rain. The head-light showed his face to be bloodless and horror-stricken.

“Cut loose from the train, Rod!” he cried in a voice husky and choked with a terrible dread. “True, word was just coming over the wire that the centre pier of Minkskill bridge had gone out from under the track, and for me to stop all trains, when that last bolt struck the line, and cut me off. If you can’t catch that special there’s no hope for it. It’s the only thing left to try.”
