"Just like a young limb," he muttered, as he watched the daring James. "I'd have done the same twenty years ago."

Jim crawled or sneaked his way along the elevated part of the roof, so that he could clutch one side or the other in case of need. The train was now winding through a narrow gulch in a line of hills and a fierce wind tore at his body as though trying to fling him loose. He felt that it was more than he had bargained for, as the grimy roof slipped this way and that under him, then there came a sudden lurch and he was lifted clear off the top of the car and one hand was wrenched loose, and in a second his feet were hanging over the side.

His other hand caught the steel rod that opens one of the small windows in the elevated roof of the car. Would it hold? On its strength depended his only chance of life. He drew himself up slowly with every ounce of his strength. The rod bent but held and once more he was back on the roof. So he took his perilous way along and at last he reached the foreward coach. The door was guarded and he came near being shot by the suspicious conductor, who took him for one of the bandits.

THE GIRL AND THE ENGINEER

Indeed Jim's appearance was much against him. He was covered with dirt and grime and coal dust. It was only by holding his ticket against the pane of glass in the door of the coach, that the conductor was made willing to admit him. But when he was informed who Jim was he treated him with due respect and even cordiality. That was pretty good for a conductor in those days.

Jim was an object of interest as he passed through the coach. He might have blushed at finding himself a hero, but if so he was perfectly disguised by his temporary color, which was decidedly dusky.

"Oh, Mamma," cried a youngster, "I'm afraid of that big black man. Will he steal me!"
