SCENERY OF SWITZERLAND. 
smooth and rounded surface of rock, can be traced 
over the Col des Montets between Valorcine and 
Argenti^re, a height of 1474 metres, at the Chalet 
de Pliampra, 2080 metres, and to the summit of the 
Posettes, 2208 metres. 
At the bend of the river Arve, opposite Les 
Houches, where the river turns abruptly into a trans- 
verse valley, the rocks are greatly glaciated. At 
Chatelard, near Servoz, at the right side of the road, 
are several very fine Giants’ Caldrons. 
Below Servoz the river again turns and enters 
another longitudinal valley. Further down on the 
right side between Combloux and Sallenches, M. 
Rendu long ago remarked with surprise that the cul- 
tivated ground rose to a certain height, and was then 
suddenly cut off by a belt of wood. This he found 
was due to a lateral moraine, the great blocks render- 
ing cultivation impossible. It is one of the most re- 
markable groups in the Alps, and is probably due to 
its position just opposite the defile of Servoz, by 
which the great glacier descended into the valley of 
Sallanches. The moraine does not cease at Sal- 
lanches, but continues all down the defile of Mag- 
land. It exists, however, on the left side only. Not 
a single block of Granite occurs on the right any- 
where in the whole defile. Why is this?
