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, preceded by a wild light, slowly advanced, appearing still larger through the mist, which gave it a fantastic aspect. No train was expected from the east, neither had there been time for the succour asked for by telegraph to arrive; the train from Omaha to San Francisco was not due till the next day. The mystery was soon explained.
