re'ge, a mountain of Switzerland. It rises from the northwest shore of Lake Lucerne, a few miles from the Swiss city of that name. The summit commands a magnificent view of lake and mountain. Lake Zug lies on the north. Lake Lucerne, with its numerous arms, stretches away in the opposite direction. Tell's Chapel stands on the Lucerne shore at the south of the mountain below. The St. Gothard, Pilatus, the Jungfrau, and the snowcapped peaks of Uri and the Bernese Alps may be seen for a distance of 120 miles. The Rigi may be ascended by a few hours' climb or by either of two inclined railways. There are mammoth hotels at the top. During the tourist season they are thronged by people from all parts of the world. A veritable babel of languages is heard. In his Innocents Abroad Mark Twain gives a humorous and, of course, exaggerated account of his experience in watching for sunrise on the Rigi.
