to 48 and beyond. At 14 a stray fragment of zoisite vein 

 matter 3" thick with quartz in the centre. Numerous quartz 

 veins occur in this ridge; near 48 they contain crystals of 

 feldspar. Here and there this schist contains flakes of bronze 

 colored mica. Descending the east side of the ridge toward 45 there 

 is finely stratified mica schist, such as are used for the manufacture 

 of scythe stones, dipping W.NW. 40°-45°, under the hornblende 

 schist just described, and it appears again on the west side of the 

 ridge near 14. Between 55 and 47 these mica schists form the west 

 side of ridge V, and at 54 they form the extreme northern end 

 of that ridge, reappearing, however, as a dark grey or black, very 

 finely laminated slate in a series of mounds which terminates 

 at 37. 



Ridge V is best studied between 47 and 40. Its jagged and 

 blade-like crest is hornblende schist underlying the mica schists 

 of ridge IV, and measuring about 40 / . Next eastward come 

 about 30' of mica schists (scythe stone variety) dipping 55° W. 

 NW., underlaid by hornblendic schists which descend to the 

 glen between this and ridge YI, where they are covered by debris 

 from the crest but measure at least 40'-50' with a W.NW. dip. 



Ridge VI. The shortest distance between the hornblende 

 schist of the preceding ridge and the nearest outcrop on this one 

 is not far from 75'. The width of the southern extremity is 

 perhaps 75'. This is an abrupt face, a fissure plane with the 

 usual W.NW. direction and consists of quartzite conglomerate. 

 These vertical fissures recur along the whole ridge every 10'-20', 

 as may be seen on the west side. Crossing these in a horizontal 

 direction may be seen a series of fractures, joints, which dip 

 E.SE., and cut up the whole west side into parallelograms. The 

 dip of the conglomerate is visible on the east side of the southern 

 end, 50° W.NW., and again at 41, 45°-60° W.NW. The alcove 

 called Berkeley's Seat on the southern face is due to the meeting 

 of planes of a joint, a fissure and several planes of stratification, 

 together with the disintegrating influences of the weather. 1 The 

 pebbles of the conglomerate as well as the cement abound in 

 crystals of magnetite. 



The general dip of the west face of the ridge is about 70° W. 

 NW. At 40 the conglomerate is overlaid by about 40' of hard 



1 Indian fires have also probably enlarged the opening.
