dians might still be engaged in pillaging. Nevertheless, he began to
rebuild the fire in the furnace; the pressure again mounted, and the
locomotive returned, running backwards to Fort Kearney. This it was
which was whistling in the mist.

The travellers were glad to see the locomotive resume its place at the
head of the train. They could now continue the journey so terribly
interrupted.

Aouda, on seeing the locomotive come up, hurried out of the station,
and asked the conductor, "Are you going to start?"

"At once, madam."

"But the prisoners, our unfortunate fellow-travellers--"

"I cannot interrupt the trip," replied the conductor. "We are already
three hours behind time."

of the densely falling snow.

The detective had remained behind.

Several hours passed. The weather was dismal, and it was very cold.
Fix sat motionless on a bench in the station; he might have been
thought asleep. Aouda, despite the storm, kept coming out of the
waiting-room, going to the end of the platform, and peering through the
tempest of snow, as if to pierce the mist which narrowed the horizon
around her, and to hear, if possible, some welcome sound. She heard
and saw nothing. Then she would return, chilled through, to issue out
again after the lapse of a few moments, but always in vain.

Evening came, and the little band had not returned. Where co
