218 J. D. Dana—Taconie Rocks and Stratigraphy. 
The dip of this limestone, as the T’s on the map indicate, is

of the overlying schist. Fig. 13 shows the position of the

The limestone in its upper portion is often impure with 
‘‘canaanite” or massive white pyroxene. The beds of schist 
ceous quartzyte intervenes in places. The thickness of the 
quartzytic layer I could not determine because sandy 8° 
usually conceals it. In the third section (fig. 15), large masses 
of hard quartzyte lay over the surface, as evidence 0°
