The road led through a wood and then up a long hill. The snow was so thick that Dave had all he could do to keep Plum in sight. The bully of the Hall walked rapidly, his head bent low and his hands rammed well down in his overcoat pockets.

The high ground at the top of the hill gained, Plum struck off to the southeast, in the direction of the railroad tracks. Inside of five minutes he reached a point where the tracks ran through a deep cut. On either side were tall trees, and the sloping banks of the cut ran down almost to the rails, now covered with snow.

At the edge of the cut Plum paused again. He looked up and down the opening, as if undecided in what direction to turn. Far away a locomotive whistle sounded and a freight train appeared in sight, rolling forward rapidly on a slight down-grade.

As the freight train came closer Plum prepared to climb down the steep slope of the cut. All was covered with ice and snow, and he had taken but a dozen steps when he lost his footing and his hold and rolled over and over. Then he struck a projecting rock and the next instant pitched forward on his head, rolled over and over once more, and landed squarely on the tracks below!

Dave was close to the edge of the cut and saw the whole occurrence. When Plum struck on his head he uttered a deep groan, showing that he was injured. Then, as he lay on the tracks, he did not move.

"He is unconscious!" thought Dave, and a chill of horror swept over him. He looked along the cut. The freight train was sweeping forward, directly for the unconscious youth. In half a minute more it would reach Plum and run over him. He heard a fierce whistle, as the locomotive engineer gave the signal for brakes, and the engine itself was reversed. But the grade was too great and the train too heavy for a sudden stop.

Dave's heart leaped into his throat. Was Plum to be ground up under his very eyes? He had no great love for the bully, but at that moment his heart went out to him as if he were a brother.

"I must save him—if I can!" he told himself. "He must not be killed if I can help it!" And then, throwing himself face downward, he slid over the ice and snow to the bottom of the cut. His hands and face were scratched, but he paid no heed. As he touched the bottom he leaped up. The train was less than fifty feet away, the wheels grinding sharply on the tracks. He made one wild leap forward, caught Plum by the feet and dragged him out of harm's way. Then the train rolled on, coming to a stop a few seconds later.
