Neither the engineer nor the stoker was dead, and, after remaining for some time in their swoon, had come to themselves. The train had then stopped. The engineer, when he found himself in the desert, and the locomotive without cars, understood what had happened. He could not imagine how the locomotive had become separated from the train; but he did not doubt that the train left behind was in distress.

He did not hesitate what to do. It would be prudent to continue on to Omaha, for it would be dangerous to return to the train, which the Indians 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."

"And when will another train pass here from San Francisco?"

"To-morrow evening, madam."

"To-morrow evening! But then it will be too late! We must wait--"

"It is impossible," responded the conductor. "If you wish to go, please get in."

"I will not go," said Aouda.

Fix had heard this conversation. A little while before, when there was no prospect of proceeding on the journey, he had made up his mind to leave Fort Kearney; but now that the train was there, ready to start, and he had only to take his seat in the car, an irresistible influence held him back. The station platform burned his feet, and he could not stir. The conflict in his mind again began; anger and failure stifled him. He wished to struggle on to the end.

Meanwhile the passengers and some of the wounded, among them Colonel Proctor, whose injuries were serious, had taken their places in the train. The buzzing of the over-heated boiler was heard, and the steam was escaping from the valves. The engineer whistled, the train started, and soon disappeared, mingling its white smoke with the eddies 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 could they be? Had they found the Indians, and were they having a conflict with them, or were they still wandering amid the mist? The commander of the fort was anxious, though he tried to conceal his apprehensions. As night approached, the snow fell less plentifully, but it became intensely cold. Absolute silence rested on the plains. Neither flight of bird nor passing of beast troubled the perfect calm.

Throughout the night Aouda, full of sad forebodings, her heart stifled with anguish, wandered about on the verge of the plains. Her imagination carried her far off, and showed her innumerable dangers. What she suffered through the long hours it would be impossible to describe.

Fix remained stationary in the same place, but did not sleep. Once a man approached and spoke to him, and the detective merely replied by shaking his head.

Thus the night passed. At dawn, the half-extinguished disc of the sun rose above a misty horizon ; but it was now possible to recognise objects two miles off. Phileas Fogg and the squad had gone southward; in the south all was still vacancy.
