at M. This also accounts for the secondary level of terraces found 
in valley A at this elevation. 
At the same time the lateral drainage from the ice was concen- 
trated in a channel between the ice-front and the face of the steep 
hill due west of Claylick. This accounts for the steepening of 
the slope near the base of the hill as shown in fig. 5. The same 
slight retreat of the ice-front permitted the stream flowing over the 
bench at M to slip down off from it and occupy the natural channel

between the glacier and the base of the slope; thus a similar steep- 
ening of the slope at this point was produced. The channel at 
before this oscillation, had become so firmly established that 
it retained its stream of water until the abnormal conditions due to 
the presence of the ice had been entirely dissipated. Then, a 
small stream working in the soft gravels, north of the outlier pro- 
duced hy N j captured and deflected the creek from its rock chan- 
nel. This piracy can still be traced in detail in the former 
courses of the creek and its small branches.
