Plate II 



Upper figure. Primary flow lines in pink granite gneiss; pegmatite and 

 ordinary granite intergrading and interbanded. Looking north. 



From a granite lens in middle limb of sigmoid fold. 



Lower figure. Dissolution of amphibolite in granite gneiss. The chain 

 of elliptical dark patches in the center of the picture are of amphibolite in 

 the act of being disintegrated by the granite; the black streaks adjoining and 

 elsewhere are caused by the rolling out of more or less completely melted 

 fragments of various sizes, and their partial incorporation into the granite 

 magma. A typical mixed rock. Looks northwest ; one-eighth natural size. 



One and three-tenths miles southwest of Pierrepont, three-tenths of a 

 mile west of the road.
