STRIKE AND DIP. 

 IV. HORNBLENDE, FELDSPAR AND MICA. 



This variety approaches gneiss, but it cannot be called gneiss, as the hornblende predominates. Tho 

 mica is usually in small quantity, and the feldspar and quartz sometimes traverse the rock in numerous 

 minute veins. 



STRIKE AND DIP OF THE STRATA. 



Our observations upon the jointed and cleavage (?) structure of the gneiss and hornblende schist have 

 been so few, that they need not be mentioned. The different beds described belong properly to different 

 rocks ; but as we had separated the observations upon the strike and dip of the hornblende schist into a 

 list by themselves, it was thought best to present them in this form. 



As this rock is associated with different rocks (in some cases it being difficult to determine to which of 

 the great groups it belongs), we simply record the different observations without classification, beginning at 

 the south part of the State, and working northwardly.
