It was already getting dusk, and by the time he had walked half a mile it was almost dark. He had traversed a level stretch of rail till now, but was delighted to find that he had reached a steep up gradient.

"It is a heavy train," he thought, "and will be sure to slow down here. I must manage to get aboard."

He sat down and waited patiently, wondering the while what Amos was doing, and what had happened during his interview with Simpkins. If only he had known it, that interview had been more than humorous. For the astute little showman had been suddenly afflicted with forgetfulness. He could hardly even remember Simpkins, much less the fact that he was a constable. As to his man, well, he might be wandering in the town. In any case Simpkins might see him when he cared to call. Yes, he was a good young chap, had been with the van quite a time, but how long he wasn't altogether certain. In fact, Amos threw abundance of dust in the eyes of the constable. But he did not smother his natural suspicions.

"I believe the old hound knows a heap more than he will say," growled Simpkins as he walked away. "And I can't help thinking that thar was something about that man on the stage which struck me as being sort of familiar. Ef it was young Jack Kingsley, whew!"

He whistled loudly, for he realized that re-arrest of the prisoner would mean commendation for the constable, and promotion to a certainty. The very thought stimulated him in his efforts. He went straight off to the station, and was just in time to inspect the train about to leave, from the engine right back to the truck trailing at the end.

"Not here," he said as he walked away, having seen the train run out of the station. "He'll be in the town, I expect. Now that I come to think about it, that fellow on the stage was jest about the right size for the prisoner, and, in spite of the beard he wore, about the same age. Gee!"

There was something else which struck him, something again to do with the pose of the man he had in his mind's eye. And now he remembered that he had often and often watched Jack as he sat in the court under trial. His pose there was precisely that of the man he had so lately seen on the conjurer's stage. In a flash it occurred to him that this must be the prisoner he sought, and he went off at a run to speak again with Amos. Meanwhile the train had run from the town at a smart pace, which, however, dropped as it ascended the rise.

"It will be a job to clamber aboard, all the same," thought Jack, as he saw it coming. "I suppose it is doing seventeen miles an hour. But I have got to get aboard somehow, if I have to dive for it."

He stood back from the rails, so that the engine lamps should not show him to the drivers. But the instant it thundered past he stepped briskly forward. Yes, the long line of heavy vehicles was pounding along at a smart pace, and, more than that, their height above the rails was greater than he had reckoned for. He watched the carriages like a cat, seeking for a handy rail. But one after another they swung past till the last was near at hand. It was a species of conductor's van, and the step descended close to the ground. There was a strong rail beside it, and to this Jack clutched as it came level with him. In spite of the fact that he had begun to run with the train, he was jerked off his feet; for the vehicles were gathering pace every second. But Jack was not to be easily beaten. He clung desperately with one hand to the rail, while he gripped the step with his other. Then he managed to swing his body till it leaned on the step, and, later, to lift himself clean on to it.

"So far so good," he thought. "Now I make back for the truck behind. I'll wait till I have gained my breath, for there is no hurry, and no bridges likely to strike me. The train does not stop for twenty miles, and, as it has to ascend a long gradient, it takes a time to do the work and cover the distance. Gee! That dragging knocked my boots about."
