He began to accuse and abuse himself, and, as if he were
director of police, administered to himself a sound lecture for his
greenness.

"I have been an idiot!" he thought, "and this man will see it. He has
gone, and won't come back! But how is it that I, Fix, who have in my
pocket a warrant for his arrest, have been so fascinated by him?
Decidedly, I am nothing but an ass!"

So reasoned the detective, while the hours crept by all too slowly. He
did not know what to do. Sometimes he was tempted to tell Aouda all;
but he could not doubt how the young woman would receive his
confidences. What course should he take? He thought of pursuing Fogg
across the vast white plains; it did not seem impossible that he might
overtake him. Footsteps were easily printed on the snow! But soon,
under a new sheet, every imprint would be effaced.

Fix became discouraged. He felt a sort of insurmountable longing to
abandon the game altogether. He could now leave Fort Kearney station,
and pursue his journey homeward in peace.

Towards two o'clock in the afternoon, while it was snowing hard, long
whistles were heard approaching from the east. A great shadow,

The locomotive, which was slowly approaching with deafening whistles,
was that which, having been detached from the train, had continued its
route with such terrific rapidity, carrying off the unconscious
engineer and stoker. It had run several miles, when, the fire becoming
low for want of fuel, the steam had slackened; and it had finally
stopped an hour after, some twenty miles beyond Fort Kearney. 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
