SCENERY OF SWITZERLAND. 
Fig. 149 gives a section across the Ticino and 
Bernina Massives, from Weissberg in the north, to 
Dubino in the south. 
The L. of Lugano owes its complex form to the 
fact that it consists of two longitudinal, and two 
transverse valleys dammed up by moraines. 
Scegreblrgo Tessiner und Bernina Maesiv. Liro-Maesiv. 
It is remarkable that the Lago d’Orta differs 
from the other Italian lakes in having its outflow, 
not in the natural line of the drainage, viz. to the 
south, but on the contrary to the north. This is 
due to the southern end being closed by a 
moraine.
