sheet from the contact east to the Rowe schist. The area covered by these 

 transitional coarse gneisses therefore occupies the geological position of the 

 conglomerate-gneiss, a tact which the occurrence of the "loose ledges" of 

 conglomerate seems to confirm. North of the lake the continuation of this 

 coarse transitional gneiss is found at intervals with the same strike and dip. 

 From here for "2\ miles south the place which should be occupied by 

 the white gneiss-conglomerate is covered with drift, anil not a single out- 

 crop is found. The albite-schist, with a constant north to south strike, 

 borders on the east and the granitoid gneiss on the west. Opposite the 

 post-office of Savoy Center the next outcrop is found. This is quite con- 

 glomeratic in aspect, with round, blue quartz or granulite pebbles, and a 

 strike north 15° west and dip 45° east. Intervening between this and the 

 typical granitoid gneiss to the west we find the same coarse transitional 

 gneiss, with somewhat varying strike and dip. Continuing south from this 

 last exposure, on the road leading to Savoy hollow, we find occasional 

 outcrops of coarse transitional gneiss with the same nearly north to south 

 strike and easterly dip. This brings us about to the extreme point of the 

 area of granitoid gneiss and to the white gneiss-conglomerate band fol- 

 lowed around from the west side. The relations of the rocks at this point 

 are peculiar and deserve a special description. The topography here is 

 well marked. It is easily seen on the map that a long spur runs out from 

 the point of the granitoid gneiss for a mile and more toward Savoy hollow. 

 This spur is caused by the meeting of the white gneisses of the east and 

 west areas, those on the east coming down with a north to south strike and 

 easterly dip, those on the west striking across with a nearly east to- west 

 strike and northerly dip. We rind on the spur the rocks very sharply 

 crumpled, representing the sudden turn of strike and dip; some layers 

 striking east and west can be traced to the place where they curve around 

 and run southerly with a steep easterly dip. At one point on the spur, 

 about a mile north of Savoy hollow, we find a curious curving series of 

 outcrops of a very coarse porphyritic gneiss, containing large rounded 

 feldspar crystals, blue quartz, etc. — an "Augen" gneiss. The outcrops on 

 the east side strike north 5° west and dip about vertically. This gradu- 

 ally curves around to an east and west strike and steep southerly dip, then
