He looked away from me, reached over and started the pump, and said: "Don't you know?"

"No, sir, I have not the slightest idea."

"Then you stay, and I'll change," said he, with a determined look, and leaned out of the window, and said no more all the way in.

I did not go home that day. I cleaned the "Roger William" from the top of that mountain of sheet-iron known as a wood-burner stack to the back casting on the tank, and tried to think what I had done wrong, or not done at all, to incur such displeasure from Dillon. He was in bed when I went to the house that evening, and I did not see him until breakfast. He was in his usual spirits there, but on the way to the station, and all day long, he did not speak to me. He noticed the extra cleaning, and carefully avoided tarnishing any of the cabfittings;—but that awful quiet! I could hardly bear it, and was half sick at the trouble, the cause of which I could not understand. I thought that, if the patched bill had anything to do with it, Christmas morning would clear it up.

Our return trip was the night express, leaving the terminus at 9:30. As usual, that night I got the engine out, oiled, switched out the cars, and took the train to the station, trimmed my signals and headlight, and was all ready for Jim to pull out. Nine o'clock came, and no Jim; at 9:10 I sent to his boarding-house. He had not been there. He did not come at leaving time—he did not come at all. At ten o'clock the conductor sent to the engine-house for another engineer, and at 10:45, instead of an engineer, a fireman came, with orders for John Alexander to run the "Roger William" until further orders,—I never fired a locomotive again.

I went over that road the saddest-hearted man that ever made a maiden trip. I hoped there would be some tidings of Jim at home—there were none. I can never forget the blow it was to "mother;" how she braced up on account of her children—but oh, that sad face! Christmas came, and with it the daughter, and then there were two instead of one: the boy was frantic the first day, and playing marbles the next.

Christmas day there came a letter. It was from Jim—brief and cold enough—but it was such a comfort to "mother." It was directed to Mary J. Dillon, and bore the New York post-mark. It read:

"Uncle Sam is in need of men, and those who lose with Venus may win with Mars. Enclosed papers you will know best what to do with. Be a mother to the children—you have three of them.

"James Dillon."
