true of the broader eastern belt at J. Hough's and at Mill Village. At 

 the former place hornblende is present, the strata inclining 75° N. 55° E. 

 The following is the order of rocks from west to east across this mica- 

 ceous band along Mink brook and through Mill Village: Mica schist, 

 near Hon. I. Ross's, on road turning to Lebanon, dipping 65° easterly; 

 schist, 65° E.; decomposing mica schist, 45° N. 6^)° E.; epidotic mica 

 schist or gneiss at Mill Village store, 65° N. 30° E. There is an abun- 

 dance of similar ledges to the Baptist church. East, the same rocks ex- 

 tend about a quarter of a mile. A few rods north of the church there is 

 a massive micaceous schist, resembling hornblende rock. A real horn- 

 blende schist by Mrs. Kinne's, about a mile north, dips 80° N. 70° E. 

 On the hill east of Mill Village there are light-colored soft schists, show- 

 ing the presence of pyrites abundantly, on exposure to the air, dipping 

 55° N. 65° E. Passing southerly on a road to East Lebanon, schists ap- 

 pear more like those upon Prospect hill. At W. Knight's there is gneiss 

 dipping 70° S. 50° E. Over the ridge, about on the town line, the schist 

 has a greenish tint, dipping S. 45° E. Near A. Freeman's, ferruginous 

 schists dip 80° S. 23° E. Between this hill and the high land west of 

 the road from Mill Village to Lebanon is a deep and gradually broaden- 

 ing valley, in which the ledges are concealed ; and those which we should 

 expect to find there are of the same character with the schists under con- 

 sideration. Li passing to the south of the village we seem to meet better 

 defined mica schists, referable to the Coos group, occupying the place of 

 much of the rock running south from Mill Village ; but the outside vein 

 of the Bethlehem area from Lebanon village to its extreme southern end, 

 and thence on the west side through Lebanon and Hanover, is clearly 

 composed of this feldspathic mica schist. Among other localities I may 

 cite the school-house north of F. Peabody's, and the north edge of the 

 Colburn hill in Lebanon (70° N. 80° W.); the valley of Mink brook, and 

 the west base of Corey hill in Hanover (50° N. 80° W.). 



The dark schists just spoken of surround a massive protogene gneiss, 

 which is the characteristic Bethlehem rock. Its northern end is the top 

 of the hill back of A. P. Balch's stone house. On Corey hill, near the 

 summit and by H. H. Marshall's, it has been quarried for building. The 

 foundations of Culver Hall came from the latter; and those of the Epis- 

 copal church in Hanover from the former quarry. Other openings are
