Other Montalban Rocks. 



In the north-east part of Victory, at the forks of the road east of 

 Moose river, gneiss, with fibrolite, dips S. 60° W. 75°. On East Haven 

 mountain an argillaceous mica schist dips S. 52° E. 58°. In the east part 

 of Burke, at the end of a road going north from \ | 

 the main road, argillaceous mica schist, with \ | 

 staurolite in small crystals, dips S. 44° E. 60°. 1 1 

 On the north spur of Umpire mountain there is | ^ 

 argillaceous mica schist, with andalusite and fib- | ^ 

 rolite — dip exceedingly variable ; with the schist 

 there is granitic gneiss; in the central part of 

 Victory, on Bog brook, granitic gneiss outcrops. 

 In the north part of Kirby, in the gap between 

 East Burke and Kirby mountains, a mica schist, 

 passing into gneiss containing fibrolite, dips east- 

 erly. South of Kirby mountain gneiss, with fib- 

 rolite, dips N. 54° E. 70°. On Miles mountain, 

 in Concord, the rock is gneiss, with fibrolite. In 

 a cleared field, on the south-west side, the dip is 

 N. 40° W. 28°. The rock is very siliceous and is 

 somewhat calcareous. In the woods above the 

 field just mentioned the dip is N. 62° E. 55°; 

 top of ridge, dip N. 58° E. 70°; at the summit 

 of the mountain the dip is W. 80°. 



Older Rocks. 



The rocks of the Atlantic series here described 

 are probably older than the Montalban. In the 

 north part of Milan, on the river road, near a 

 school-house, the rock is gneiss. Here it con- 

 tains a greenish mica, and dips N. 50° W. 58°.
