His face was partly averted, as he lay upon his side.

But the detectives saw that he was a man of about fifty, his portly form clad in a dark suit of clothes. His head was partly bald on top and his hair was gray. There was a closely-trimmed mustache of the same color on his upper lip, and his flesh, although pallid, had not yet changed to the waxen hue of death.

It was evident that he was a victim of foul play, for his hands were bound behind his back, and his ankles tied together, while a gag was secured over his mouth as if to stifle his outcries.

The detectives had no chance to observe any more, just then, for there suddenly sounded a quick danger signal of the locomotive's whistle.

The engineer shut off steam, put on the brakes, and the startled conductor rushed from the car with the lantern, leaving the place in gloom.

"What can be the matter?" muttered Old King Brady.

"There's a fire on the track ahead!" said Harry, peering out the side door.

"Where are we?" queried the baggage master, hastily.

"Next to a big swamp," replied Harry. "And, by Jove—see—see! There's an obstruction—a heap of sleepers piled across the rails beyond the bonfire."

"What the deuce can that mean?" muttered Old King Brady. "Bandits trying to rob this train? It don't seem possible, in this neighborhood."
