Conventions same as in figure 1 very favorable because of its medium-grained texture and homo- geneity in large masses. The closely associated Grenville rocks, on the other hand, are very variable in composition, generally dis- tinctly banded, and especially rich in limestone, this last feature rendering the Grenville unusually weak and liable to erosion. So far as the mapping has progressed the syenite-granite series and.
