arenaceous sandstone schists, which, near Perry stream, dip N. 36° E. 

 75°. Southward along the old "tote "-road the diorite alternates with the 

 schist. The general dip is N. 34° E. yS'^, and both rocks are quite alike 

 in texture, except that for a mile and a quarter, a little east of north from 

 the Fletcher place, the diorite is more schistose than along the "tote"- 

 road. The dip here is N. ^y° W. 75°. West of Round pond there are 

 immense masses of the diorite. The high hill to the west and north-west 

 is composed of diorite and arenaceous sandstone schist. The schist on 

 the north side of the hill dips N. 48° E. 78''. This extends twenty-five 

 yards ; then a band of diorite has a width of five hundred yards. This 

 is succeeded by a schist that dips N. 38^ E. 85°. 



NoilTHWARD. 



We have already called attention to the fact that the green chloritic 

 schist is intimately associated with arenaceous sandstone schist. Two 

 and a half miles above Second lake, near the Connecticut, the arenaceous 

 schist dips N. 26° E. 82°. Towards Second lake, but to the west on 

 Cobble hill, where the arenaceous schist is largely developed, the dip is 

 N. 47° W. 68°. Near the lake, south-east of Cobble hill, the same schist 

 dips S. 50° E. 22°, thus forming an anticlinal axis. A mile and a half 

 north of Second lake, between the Connecticut and East inlet, there is a 

 ridge of green chloritic schist, that dips N. 50° W. 6S°. On a hill south- 

 west of the lake the same schist dips N. 47° W. 68°. In the small area 

 of green chloritic schist on the head waters of the Magalloway, east of 

 the Coos group, the rock dips S. 47° E. 65°. 



In the gneissic area on the ridge north-west of Mt. Carmel, on account 

 of the jointed structure of the rock masses, it is difficult to determine the 

 dip; but, as there is a similar area west of Parmachena lake, it is quite 

 probable that this is a lower member of the axis embracing Mt. Carmel, 

 Mt. Prospect, and Mt. Bosebuck. 



On Spring hill, two and a half miles east of Second lake, a gray sili- 

 ceous schist dips N. 57° W. 70°. On the Little Magalloway river, three 

 fourths of a mile from the state line, an argillaceous schist dips S. 31° E, 

 80°. The same distance north of this stream, towards Mt. Carmel, the 

 schist dips N. 48° W. 65°. A mile and a half north of the stream the
