THE (iOSHKN ANTICLINK. 175 



up tlie steep hill, T have found, at the abrupt transition l)etween the chlorite- 

 sehists and the serieite-schists, siyns of the continuation of the fault, in 

 the impregnation of the rock with fen-uginuous (juartz veins. 



An interesting- vein occui-s in the deep, picturesque gorge below C. 

 Colby's mill, near the town house in Hawley. It is a vein, 14 feet thick, 

 of quartz with nuich hematite disseminated, and tinted Hesh-color from 

 manganese. There has been some work done here in opening the vein. 



Another vein occm's here on the hillside east of M. V Cressv's house. 

 This rock is imjjregnated with hematite, and great masses of interlaced 

 epidote crystals occur here. It has been tested with a diamond drill to the 

 depth of 100 feet. 



On the south face of the high hill a mile and a half north of Charle- 

 mont station is a bed of magnetite G feet wide, which was worked a little 

 over forty years ago. It is for the most part verv quartzose, except 1 to 3 

 inches at the center, and lies in the fiisciculite-sericite-schist. 



THE GOSHEN ANTICLINE. 



On the line between Chesterfield and Goshen, and stretching east 

 nearly to the center of the latter town, is a most interesting outcrop of the 

 rocks of this series, isolated, and surrounded on all sides by the newer forma- 

 tion. It is a broad oval, with its long axis parallel with the meridian, and 

 the beds are arranged as a quaquaversal or short anticline, with high dips 

 on the east and low ones on the west, and with a fault crack along the crest 

 having a considerable upthrow on its west side From the frialjle nature of 

 the rocks this anticline is sunk by erosion into a peculiar, deep, oval valley, 

 which separates the two towns and in which Burnell's pond lies The area 

 is framed in its whole circumference by a bed of fine-grained, light-gray 

 granitoid gneiss about 50 feet thick, which I have assigned to the upper 

 series. 



Commencing at the north end of the series, just west of W. J. Ball's 

 house, the rock is a white, friable, granular schist, containing a shining black 

 biotite on the distant lamination faces and ver}- large, scattered garnets, and 

 varying from a quartz-schist to an almost (piartzless biotite-schist. 



Farther west the same biotite-schist becomes hornblendic, like the 

 "fasciculite"-schist, and is replaced by a black amphibolite. The same 

 schists are continued down the lower (eastern) ])ortion of the western wing
