“Don’t be alarmed, Tobin,” he said, reassuringly; “the Company can’t very well spare your services, and have no idea of doing so. If you can make it convenient I should like to have you take out number 29 to-night, and, as you will need an extra hand, I have decided to send young Blake on the same train; that is, if it will be agreeable to you to have him.”

Number 29! The Continental Express Company’s Special! Why, only passenger conductors had that train! What could Mr. Hill mean?

“It’s all right, Tobin,” continued that gentleman, noting the other’s embarrassment; “your name has gone on to the passenger list, and if you do as well there as you have with your freights I shall be more than satisfied. I hope this change strikes you as being one for the better also?” he added, turning to Rod.

“Yes, sir, only——” began Rodman, who was about to say something concerning his desire to be made a fireman, when he suddenly remembered that Truman Stump had requested him not to speak of it just yet.

“Only what?” asked Mr. Hill, a little sharply.

“I was afraid I hadn’t experience enough,” answered Rod.

“That is a matter of which I claim to be the best judge,” replied the Superintendent, with a smile. “And if I am satisfied of your fitness for the position you certainly ought to be. Now, Tobin, look lively. Number 29 must be ready to leave in half an hour. Good-night and good luck to you.”

Thus Conductor Tobin’s long and faithful service, and Brakeman Joe’s suffering, and Rod Blake’s strict attention to duty were all rewarded at once, though in Rodman’s case the reward had not taken exactly the shape he desired. Still, a promotion was a promotion, and where there were so many competitors for each upward step, as there always are on a railroad, it was not for him to grumble at the form in which it came.

So as the young railroad man gathered up his few belongings, he gratefully accepted the congratulations of his friends. A few minutes later he bade freight conductor Joe good-by, and in company with passenger conductor Tobin he left caboose number 18 with much the same feeling that a young scholar leaves his primary school for one a grade higher.

Number 29 was a peculiar train, and one that Rod had often watched rush past his side-tracked freight with feelings of deep interest, not unmixed with envy. It always followed the “Limited,” with all the latter’s privileges of precedence and right of way. Thus it was such a flyer that the contrast between it and the freight, which always had to get out of the way, was as great as that between a thoroughbred racer and a farm-horse. It was made up of express cars, loaded with money, jewelry, plate, and other valuable packages, which caused it to be known along the road as the “gold mine.” In its money-car was carried specie and bank notes from the United States Treasury, and from Eastern banks to Western cities. Thus it was no unusual thing for this one car to carry a million dollars’ worth of such express matter. Each car was in charge of a trusted and well-armed messenger, who locked himself in from one end of his run to the other, and was prepared to defend the valuables entrusted to his care with his life. Thus number 29 was one of the most important as well as one of the very fastest trains on the road; while to run on it was considered such an honor that many envious glances were cast at Rod as he stood on the platform beside it awaiting the starting-signal.
