the conductor passed through the
cars to the rear of the train. The last car was only occupied by a
dozen passengers, whom the conductor politely asked if they would not
be so kind as to leave it vacant for a few moments, as two gentlemen
had an affair of honour to settle. The passengers granted the request
with alacrity, and straightway disappeared on the platform.

The car, which was some fifty feet long, was very convenient for their
purpose. The adversaries might march on each other in the aisle, and
fire at their ease. Never was duel more easily arranged. Mr. Fogg and
Colonel Proctor, each provided with two six-barrelled revolvers,
entered the car. The seconds, remaining outside, shut them in. They
were to begin firing at the first whistle of the locomotive. After an
interval of two minutes, what remained of the two gentlemen would be
taken from the car.

Nothing could be more simple. Indeed, it was all so simple that Fix
and Passepartout felt their hearts beating as if they would crack.
They were listening for the whistle agreed upon, when suddenly savage
cries resounded in the air, accompanied by reports which certainly did

Colonel Proctor and Mr. Fogg, revolvers in hand, hastily quitted their
prison, and rushed forward where the noise was most clamorous. They
then perceived that the train was attacked by a band of Sioux.

This was not the first attempt of these daring Indians, for more than
once they had waylaid trains on the road. A hundred of them had,
according to their habit, jumped upon the steps without stopping the
train, with the ease of a clown mounting a horse at full gallop.

The Sioux were armed with guns, from which came the reports, to which
the passengers, who were almost all armed, responded by revolver-shots.

The Indians had first mounted the engine, and half stunned the engineer
and stoker with blows from their muskets. A Sioux chief, wishing to
stop the train, but not knowing how to work the regulator, had opened
wide instead of closing the steam-valve, and the locomotive was
plunging forward with terrific velocity.

The Sioux had at the same time invaded the cars, skipping like enraged
monkeys over the roofs, thrusting open the doors, and fighting hand to
hand with the passengers. Penetrating the ba
