722 REGINALD ALDWORTH DALY 
At many places along its western margin the porphyritic 
granite cuts the granitite, but often passing into it by a zone of 
transition analogous to those described in the Winnipiseogee 
area. Thus we have added another to the crystalline terranes 
which have been profoundly affected by dynamic processes since 
their formation; they are in this respect to be contrasted with 
the younger relatively unaltered porphyritic granite, and lastly, 
they are of interest not only from their relation to the history of 
igneous activity in the state, but also from the light that they 
throw on the age and origin of the granite.
