graphitic streaks parallel to the bedding. Shearing has also produced 
in the rock, a slip cleavage at right angles to the bedding. The rock 
is defined as a feldspar schist developed from a sediment. The pres- 
ence of albite places the formation among the gneisses- It is not un- 
like much of the schistose mica-gneiss of the Piedmont plateau. 
The paper closes with a discussion of the doubtful conformity of 
the Cambrian rocks on the Pre-Cambrian gneiss. Good contacts are 
few but three are cited in the Green mountains where * there is an 
evident unconformity in the strike of the rocks. As yet the discrep- 
ancy has not been explained which exists between these localities and 
others on Hoosac mountain, where the contact is conformable. Fur- 
ther study of this and other regions is necessary vo harmonize these 
observations. a. j.
