The prairie, across which the sledge was moving in a straight line, was as flat as a sea. It seemed like a vast frozen lake. The railroad which ran through this section ascended from the southwest to the northwest by Great Island, Columbus, an important Nebraska town, Schuyler, and Fremont, to Omaha. It followed throughout the right bank of the Platte River. The sledge, shortening this route, took a chord of the arc described by the railway. Mudge was not afraid of being stopped by the Platte River, because it was frozen. The road, then, was quite clear of obstacles, and Phileas Fogg had but two things to fear⁠—an accident to the sledge, and a change or calm in the wind.

But the breeze, far from lessening its force, blew as if to bend the mast, which, however, the metallic lashings held firmly. These lashings, like the chords of a stringed instrument, resounded as if vibrated by a violin bow. The sledge slid along in the midst of a plaintively intense melody.

“Those chords give the fifth and the octave,” said Mr. Fogg.
