89) which may be connected either with this range or another to be 

 spoken of hereafter. 



Just out of the village of South Vernon, to the north-west, the quartzite 

 dips 20° N. 35° E. It is hkely this continues to join the quartzite far- 

 ther west, or No. 53, north-west from a brickyard near C. D. Severance's, 

 with the dip 25° S. 80° E. On the west side of this small hill is a sili- 

 ceous conglomerate, dipping 45° S. 80° E. I will not repeat the obser- 

 vations along the state line, where quartzite and hornblende rock alter- 

 nate, and will be noticed presently. It is not clear that the quartzite is 

 continuous from the railroad cut in South Vernon to the exposures near 

 Lily pond, though presumable. The quartz (No. 20) has a strike nearly 

 with the road, or north-westerly, between Lily pond and the state line. 

 Directly south from the pond there is a south-east dip, with irregulari- 

 ties. From here to the old fort in the north part of Vernon the outcrops 

 are easily traceable, curving from north-west to north, and then crossing 

 to connect with the quartzite in the north part of Hinsdale, The gneiss 

 east of the pond and along the direct road to Vernon is very siliceous, 

 and is with difficulty separable from it. Different observers would not 

 draw their boundary lines in the same place. By G. W. Lee's, in district 

 No. 9, the dip is east. Farther on, or near the school-house, the dip is 

 N. 48° E. Near L. C. Brooks's, the dip is 30° N. 50° E., but more east- 

 erly at the Hubbard place. This range invariably dips easterly, towards 

 if not beneath the gneiss. It is probably to be regarded as inverted, and 

 thus passing beneath the older rock, rather than resting unconformably 

 upon it. 



The following is the order of rocks for two fifths of a mile in length, 

 from the edge of the alluvium in West Northfield, along the road nearest 

 the state line, illustrated by Nos. 143-156: 



143, Quartzite, one fourth mile west of the 150, Breccia of quartzite and schistose 

 railroad,— dip, 60° S. 35° E. fragments,— dip, S. 35° E. 



144, Micaceous quartzite — same dip, also 151, Argillo-mica schist, 

 dip of 60° S. 80° E. 152, Gneissoid quartzite. 



145, 146, Quartzite, weathering as if from 153, Compact hornblende. 



feldspar. 154, 155, Staurolite mica schist,— dip, 40° 



147, Argillo-mica schist,— dip 70° S. 35° E. S. 45°-50° E. 



148, Hornblende schist, — dip, S. 38° E. 156, Mica schist, much silica, and little stau- 



149, Micaceous quartzite. rolite— quarried ; dip, 35° S. 30° E,
