“ The Pantenbrücke, thrown over the narrow cleft formed by the Linth, is one of the grandest sights of the Alps below the snow-line. There is a sulphur spring at Stachelberg, near Linthal village, and an iron spring at Elm, while in the Sernf valley there are the Plattenberg slate quarries, and just south of Elm those of the Tschingelberg, whence a terrific landslip descended to Elm (11th September 1881) , destroying many houses and killing 115 persons. A railway runs through the whole canton from north to south past Glarus to Linthal village (161/4 m.) ”
