GLARIS, one of the cantons of Switzerland, is bounded on the east, partly by the Grisons, and partly by the territory of Sargans; on the north, by the bailiwick of Gaster, and by the lake Wahlenstatt; on the east, by the canton of Schwits; and on the south, by part of the canton of Uri, and part of the league of the Grisons. It is a mountainous country, being entirely within the Alps. Near the village Ober-Urnen there is a famous mineral spring, which is sometimes hot and sometimes cold. The lake Wahlenstatt is bounded by high rocks and mountains, through one of which a road is cut. Towards the top of one of these there is a large hole, through which the sky may be seen.
