tion E, PL xix, both rocks dip west, and at 669, Section F, both are Hori- 

 zontal, the limestone underlying the schist in all cases. 



In ascending the east side of Ragged mountain over this second mass 

 of schist only westerly dips are met, hut on Sections E, <J, and again about 

 a mile south of Section < ! (localities 204, 126) there are some well-observed 

 eastern dips following westerly ones and indicating a syneline, which, proba- 

 bly being less open at this end of Ragged mountain, escapes observation. 

 Near the top is a narrow belt of calcareous schist forming a north to south 

 ravine across the ridge and connecting the limestone area of the Notch 

 with that on the' south. Beyond is a small, isolated schist area which 

 forms the south end of the top of the Ragged mountain ridge. The dips 

 continue westerly. In de- 

 scending into the Notch 

 the calcareous schist re- 

 curs, dipping 60 east and 

 indicating another svn-

 this small schist area is 

 best seen about a half a

Fig. 62.) On the east side of and close to the schist, the calcareous schist 

 (plicated) dips 90° and west at high angle; the schist (feldspathic and chlor- 

 itic) is also plicated in the same direction, with a high, easterly cleavage. 

 Again, at locality 733, about 500 feet south of the section, the two rocks 

 come in contact with westerly stratification foliation and easterly cleavage. 

 On the west side of this schist area both rocks are in contact in inverse order, 

 dipping east at a, low angle. These easterly dipping beds of the west side of 

 Ragged mountain stand out in prominent ledges which can be clearly seen 

 from thi- top of a knoll (locality 190) about half a mile south of the Bellows- 

 pipe. (See PI. xvi.) The same svncline occurs on Section F and also con- 

 tinues south of Section Gr, on the knoll just mentioned, in the limestone and 

 calcareous schist area. This limestone is very pyritiferous in places; an 

 assav of the pyrite, said to have yielded a small percentage of gold, led re-
