In such a case the rivers would tend to 
radiate with more or less regularity from the 
centre or axis of the dome, as, for instance, 
in our English lake district (Fig. 37). Der-

we account in any way, and if so how, for 
these varied directions? 
The mountains of Cumberland and West- 
moreland form a more or less oval boss, the 
axis of which, though not straight, runs 
practically from E.N.E. to W.S.W., say from

and Windermere run at right angles to this 
axis; Ennerdale Water is just where the boss 
ends and the mountains disappear; while 
Crummock Water and Waste Water lie at 
the intermediate angles. 
So much then for the direction. We have
