rock is found on Cherry mountain in Carroll, while just cast of the moun- 

 tain, in the south part of Jefferson, at a saw-mill, there is an exceedingly 

 hard granitic rock, composed of feldspar and quartz. In the south-west 

 corner of Randolph, at a saw-mill, there is a similar rock, very much 

 jointed. East of this and south of the last there are outcrops of grani- 

 toid gneiss. In Randolph the granitoid gneiss, composed largely of 

 granular quartz, extends along Moose river, nearly through the town. 

 At Gorham a rock like Concord granite outcrops near the village, where 

 it is interstratified with the White Mountain gneiss. In Shelburne there 

 are several extensive outcrops. Three fourths of a mile west of the vil- 

 lage, large C][uantities of this rock have been quarried. It appears also 

 south of the village, and extends a mile or more up Clement's brook. In 

 Martin's grant it can be seen along Peabody river, and it extends up that 

 stream to Mr. H. D. Copp's. It is likely to be found in many places 

 interstratified with the White Mountain gneiss. In Milan, three fourths 

 of a mile south-west of Higgins's mill, there is an outcrop of granite on 

 the stream that flows into the Upper Ammonoosuc, near the mill. On 

 the line of Milan and Kilkenny, on the mountain ridge known as Green's 

 cliff, there is a coarse, eruptive granite, composed of light flesh-colored 

 feldspar, dark gray quartz, and black mica. On the south-east side of 

 this ridge there is a precipitous cliff, from one hundred and fifty to two 

 hundred feet in height. At the base of the cliff there are boulders of 

 immense size, that have fallen down. One of these boulders contains 

 over thirteen thousand cubic yards. The granite extends probably a mile 

 and a half south-west from Green's cliff, and is followed by porphyrite. 



In the west part of Stark, between the Upper Ammonoosuc and the 

 Grand Trunk Railway, there is a granite quite unlike that found else- 

 where in northern New Hampshire. The feldspar is of a deep flesh- 

 color, which gives to the rock a reddish cast. East of the high hill 

 where it outcrops, up the valley, there are numerous boulders of this 

 rock, some of which have been used in the construction of abutments to 

 the bridge at Stark station. It seems to be wrought with facility, and 

 is the only workable granite found in ledges anywhere in this section 

 of the state west of the water-shed between the Androscoggin and the 

 Connecticut.
