The half-sleeping passengers were roused by the wonderful movements of the two men.

"Madmen!"

"What IS the trouble?"

Such were the exclamations, as doors slammed, and the two men swept into the next car. From coach to coach sped the pursued and the pursuer. It was a flight for life, on the part of Professor Ruggles.

His plug hat flew off in the chase, and a brakeman who confronted him in the aisle was knocked flat with terrific force.

"Murder!"

And then both men disappeared from the rear platform.

Dyke Darrel believed he had his man in a corner, when he saw him dash through the door at the rear of the long train.

Not so, however.

The desperate Ruggles was ready to do anything rather than come in contact with his relentless foe. He bounded clear of the train, landing in a soft bit of sand, sinking almost to his knees, without harming him in the least.
