Phileas Fogg was twenty hours behind time, and Passe-partout, the involuntary cause of the delay, was desperate; he had decidedly ruined his master. The detective approached Mr. Fogg, and, looking at him attentively, said, "Seriously, sir, are you really in such a hurry?" "Very seriously I am," replied Fogg. "It is absolutely necessary, then, for you to be in New York on the 11th--before the departure of the English mail-steamer?" "I have a very great interest in so doing." "If, then, your voyage had not been interrupted, you would have reached New York on the morning of the 11th?" "Yes, with twelve hours to spare." "Well, you are now twenty hours late. Twelve from twenty leaves eight--you must regain those eight hours. Do you wish to try?" "On foot?" "No, on a sledge," replied Fix; "on a sledge with sails; a man has proposed it to me." It was, in fact, the man who had spoken to Fix during the night, and whose offer he had refused. Mr. Fogg did not immediately reply, but Fix pointed out the man, and Fogg went up and spoke to him. Shortly after they entered a hut built just beyond the fort. Here Mr. Fogg was shown a very curious vehicle--a sort of sledge, with room for five or six people. A high mast was firmly supported by wire rigging, and carried a large sail; it was also furnished with a rudder. In fact it was a sledge rigged like a cutter. During the winter, on the frozen plains, the trains cannot run, and these sledges make rapid passages from station to station, and when running before the wind they equal, if they do not exceed, the speed of the train. The arrangement was soon made. The strong west wind was in their favour. The snow was hard, and Mr. Mudge, the owner, was confident of being able to reach Omaha in a few hours. Thence were plenty of trains to Chicago and New York. It was just possible to recover the lost time, and they did not hesitate to make the attempt. Mr. Fogg did not wish to expose Aouda to the cold, and suggested that she should remain at the station with Passe-partout, who would escort her to England under more favourable circumstances; but she refused to leave Mr. Fogg, greatly to the delight of Passe-partout, who would not leave his master alone with Fix. The detective's thoughts would be difficult to guess. Was his conviction shaken by Fogg's return, or did he still regard him as a scoundrel who hoped to be safe in England on his return? Perhaps Fix's opinion concerning Fogg had altered; but he would do his duty, nevertheless; and he would do his duty and hasten his return to England as much as possible. At eight o'clock the sledge was ready. The passengers took their places, the sails were hoisted, and the vehicle sped over the snow at forty miles an hour. The distance between Fort Kearney and Omaha, as the crow flies, is two hundred miles at most. If the wind held they could reach Omaha by one o'clock, if no accident happened.
