540 STRATIGRAPHICAL GEOLOGY. 



country rises gradually into a ridge, culminating at Whittemore's, between 

 seven hundred and eight hundred feet above the sea. The dip is high 

 north-west here, and there have been excavations in search of gold. The 

 west border of it is calcareous. To the south-west, and west of J. 

 Cheney's, in the edge of Goffstown, is a high peak that has not been 

 visited, but is surely made of this rock. North of M. W. Woodbury's, 

 upon Black brook, the quartz is fully displayed, dipping north-west usually, 

 but having a strike west of north for a short distance. For more than a 

 mile the country is away from roads, and the condition of the rocks can- 

 not be reported upon, but the quartz comes out on the next road, near E, 

 Jones's, on the west side. Next to the south-west our line crosses the 

 lower land of Harry brook, and the rock crops out just on the east side. 

 On the next northerly running road, near D. Kidder's, are outcrops upon 

 both sides of the road. No other outcrops are reported for three miles, 

 when it is seen along the railroad, a quarter of a mile south-east from 

 Oil Mill station, dipping 70° N. 25° W. A hard schist overlies it, and 

 there is a nondescript sort of gneiss beneath. The band may not be over 

 fifty feet wide. It next appears between the Piscataquog river and south 

 of Mrs. Morse's, in the north-east corner of New Boston. We failed to 

 find it on the two roads next crossing the line, but it appears between a 

 school-house and Miss Beard's, about three miles to the south-west of 

 Oil Mill Village. The line must curve a little more south-westerly, but 

 being somewhat back from roads, and the country covered by lenticular 

 drift hills, no satisfactory outcrop is reached till we arrive at P. Dodge's, 

 a mile and a half north-west of New Boston village. Near J. H. and L. 

 Richards's is a small drift hill chiefly composed of angular fragments of this 

 rock, so that its place cannot be far distant. At Dodge's the dip is 80° N. 

 80° W., and the band is not more than thirty feet thick. There is a possi- 

 ble exposure of the quartz west of L. Dodge's, two miles south-west of 

 the village. Here we lose sight of this rock. Diligent search has been 

 made all through New Boston and the adjacent towns, but nothing can 

 be discovered short of a hill east of J. Haggett's, in the east part of 

 Lyndeborough, probably with the usual north-west dip of the neighbor- 

 hood. The distance between these exposures is five miles, and the direc- 

 tion S. is"" W. There is said to be a little quartz by a saw-mill a quarter 

 of a mile north of the natural place for the line of outcrop to cross
