Upper figure. Hand specimen of the green schist, injected by granite, 

 shown in plate 4. The central band here is one of those which appear 

 as uniform, white bands in that view; here shown to consist of schist 

 thoroughly and minutely broken up by, and inclosed in the granite. 



Lower figure. Hand specimen of sheared, banded, acid gneiss from 

 near the shore of Wellesley island, due west of Alexandria Bay. Shearing 

 has produced numerous, slight faults, the shear planes are solidly 

 welded up by secondary minerals, and dikes of the Picton granite cut 

 across these, these of course not showing in the specimen. H. P.
