Curvatures in Gneiss. 39 1 



Curvatures in the Folia of Gneiss : Colebrook, Ct. 



These curvatures are not, however, confined to the laminae of gneiss, 

 but are sometimes seen in the strata. About one mile before reach- 

 ing the meeting house near the center of New Marlborough, on the 

 south side of the road, the the traveler will see an overhanging ledge 

 of stratified gneiss, dipping from 40° to 50° east, whose edges are bent 

 as in the annexed sketch. The whole length of the strata here ex- 

 hibited, (from A to B,) is 12 feet ; and their breadth about four feet.
