scenery of SWITZERLAND. 
in the Massives the central fold turns upward; in the 
Cjiarus double fold, downwards. 
The district contains two remarkable cases of 
rockfalls. One belonging to prehistoric times, in the 
valley of the Linth, above Glarus, was from a cornice 
named Guppen on the east flank of the GlSmisch. 
The aspect of the valley between Glarus and 
Schwanden contrasts strikingly with that above and 
below. It consists of unstratified, more or less 
angular, debris of calcareous breccia, and the stones 
show numerous marks of concussion. It consists 
principally of Malm, with a small proportion of 
Dogger, Cretaceous, and Verrucano. It rests on 
and is covered by glacial deposits, and as in other 
cases dammed up the valley and formed a lake. 
The other great rockfall, that of Elm, was the 
most disastrous which has occurred since that of the 
Rossberg. It took place on the nth of September 
1 88 1 from the side of the Tschingelberg, at a height 
of nearly 3000 feet. Over 80 houses were destroyed 
and 1 15 persons killed. The place is still a scene 
of wild desolation; —
