several outcrops to their proper places. Near the outlet of Newfound 

 lake is a fine-grained gneiss, dipping 80° S. 68° E., and also vertical. On 

 a hill west an andalusite schist dips 75° S. 65° E. Near E. Woodbury's, 

 in Hebron, near the lake and south of the section line, a Montalban rock 

 dips 70° S. 60° E. In Bridgewater, fibrolite schist crops out at N. Chap- 

 man's, a mile and a half east of a bay in the lake. At S. and N. Brown's 

 is a pyritiferous schist. The same rock near S. Fifield's dips 74° N. 50° 

 W. At J. C. Barrett's the dip is 70° S. 85° E. 



The following rocks were observed in the road from Danbury to Bris- 

 tol, down the valley of Smith's river. Porphyritic gneiss extends for a 

 mile east of the station to its junction with a hard micaceous quartzite, 

 dipping with it 80° S. 70° E. The river valley expands greatly in the 

 east part of the town, covering the ledges with low marshes and meadows, 

 the filling up of a former lake basin. There is a mica schist by T. H. 

 Danforth's, on the east side of the river. Near it, on the north side, the 

 dip is 35° N. 40° W., and the rock carries andalusite. At C. W. Buttrick's 

 and H. S. Clifford's, in the south corner of Alexandria, are fine-grained 

 gneisses, clearly Montalban in type. The dips are 60° N. 60° W., and 65" 

 S. 60° E. Near M. Gordon's are sihceous and ferruginous mica schists, 

 dipping irregularly 80° W. At school-house No. 2 is a distinct gneiss, 

 dipping 65° N. 30° E. Very near it, at J. Tilton's, the rock becomes 

 ferruginous, and dips north of west. Between the corner of Alexandria 

 and Bristol village, extensive sand deposits cover the ledges. At Bris- 

 tol we find mica schists, somewhat rusty. Following up the Pemi- 

 gewasset river from Bristol village, we see ledges of similar character at 

 G. Ingalls's and H. M. Emmons's, dipping N, 63° W. The position and 

 material are the same at school-house No. 4, and close by the river at P. 

 E. Heath's, and the rock contains andalusite. At the line between Bristol 

 and Bridgewater, a hard siliceous rock dips 80° S. 50° E. There are 

 several other ledges like it in the next three miles up the river, on the 

 west side. At the bridge leading to Ashland there is a gneiss dipping 

 63° W. This line of travel has revealed a synclinal in the east part of 

 Danbury, an anticlinal in the south part of Alexandria, a synclinal near 

 the east line of the same town, and an anticlinal in Bridgewater. Perhaps 

 the last is the same that occurs near the New Hampton bridge. 



We have indicated an anticlinal line from the neighborhood of Plymouth
