e lower spurs of the
mountainous mass which extends southward to the sources of the Arkansas
River, one of the great tributaries of the Missouri.

At half-past twelve the travellers caught sight for an instant of Fort
Halleck, which commands that section; and in a few more hours the Rocky
Mountains were crossed. There was reason to hope, then, that no
accident would mark the journey through this difficult country. The
snow had ceased falling, and the air became crisp and cold. Large
birds, frightened by the locomotive, rose and flew off in the distance.
No wild beast appeared on the plain. It was a desert in its vast
nakedness.

After a comfortable breakfast, served in the car, Mr. Fogg and his
partners had just resumed whist, when a violent whistling was heard,
and the train stopped. Passepartout put his head out of the door, but
saw nothing to cause the delay; no station was in view.

Aouda and Fix feared that Mr. Fogg might take it into his head to get
out; but that gentleman contented himself with saying to his servant,
"See what is the matter."

Passepartout rushed out of the car. Thirty or forty passengers had
already descended, amongst them Colonel Stamp Proctor.

The train had stopped before a red signal which blocked the way. The
engineer and conductor were talking excitedly with a signal-man, whom
the station-master at Medicine Bow, the next stopping place, had sent
on before. The passengers drew around and took part in the discussion,
in which Colonel Proctor, with his insolent manner, was conspicuous.

Passepartout, joining the group, heard the signal-man say, "No! you
can't pass. The bridge at Medicine Bow is shaky, and would not bear
the weight of the train."

This was a suspension-bridge thrown over some rapids, about a mile from
the place where they now were. According to the signal-man, it was in
a ruinous condition, several of the iron wires being broken; and it was
impossible to risk the passage. He did not in any way exaggerate the
condition of the bridge. It may be taken for granted that, rash as the
Americans usually are, when they are prudent there is good reason for
it.

Passepartout, not daring to apprise his master of what he heard,
listened with set teeth, immovable as a statue.

"Hum!" cried Colonel Proctor; "but we are not going to stay here, I
imagine, and take root in the snow?"

"Colonel," replied the conductor, "we have telegraphed to Omaha for a
train, but it is
