wasser, and annexed the whole of the upper province, 
which had formerly belonged to that river. 
The Schyn also gradually worked its way up- 
wards from Thusis till it succeeded in sapping the 
Albula, and carried it down the valley to join the 
Vorder Rhine near Thusis. In what is now the 
main valley of the Rhine above Chur, another stream 
ate its way back, and eventually tapped the main 
river at Reichenau, thus diverting it from the Kunkels 
and carrying it round by Chur. 
It is possible that in the distant future the Land- 
wasser may be still further robbed of its territory. 
The water of the Davos Lake, the Fltlela, the Dischma, 
and the Kuhalpthal now take a very circuitous route 
to Chur, and it is not impossible that they may be 
captured and carried off by the Plessur. 
At Sargans a somewhat similar process was re- 
peated, with the addition that the material brought 
down by the Weisstannen, or perhaps a rockfall, de- 
flected the Rhine, just as we have seen {ante, p. 198) 
that the Rhone was pushed on one side by the Borgne. 
The Rhone, however, had no choice, it was obliged 
to force, and has forced, its way over the cone de- 
posited by the Borgne. The Rhine, on the con- 
trary, had the option of running down by Vaduz to 
Rheineck, and has adopted this course.
