SCENERY OK SWITZERLAND. 
The thickness of these gravel beds at the Rigi 
(some 5000 feet) is enormous, and they appear to 
ave been folded back upon themselves, though the 
evidence is not as yet conclusive. The mountain 
forms a long ridge. At the east end the Mollasse 
beds abut against Eocene and Cretaceous strata 
which form the Hochfluh. The Rossberg is a con- 
tinuation of the Rigi. From this mountain came the 
gieat rockfall of 1806 (chap. xxn). The railway 
passes over the rockfall, and enormous blocks may 
Still be seen. ^ 
It is indeed a wonderful geological lesson to 
stand on the summit of the Rigi and use the eyes 
and the brain. The view is magnificent. We see 
seven lakes, those of lAicerne, Zug, Lowerz, Egeri, 
Baldegger, Hallwyl, and Sempach. To the north is 
the rich^ plain of Switzerland, and we can trace 
several rivers running nearly parallel with one another 
towards the Aar; to the west is the grand mass of 
latus, of great geological interest, and fascinating 
from Its medimval traditions; to the east the Rossberg 
still showing the scar of the great catastrophe of 1806 
and the two mysterious Mythen; to the south, range’ 
after range of mountains, culminating in the giants 
of the Bernese Oberland. Greatly as these latter 
appear to difter in height when we are near to them.
