(13), with a large but imperfectly exposed dike of diabase, 

 while farther east we are able to identify slates 12 and 10 and 

 conglomerates 11,^, and 7 ; and north of the swamp, apparently 

 conglomerates 5 and 3, in very obscure outcrops. Several of 

 these outci'ops are not marked on the maj), and otlu^i's are 

 incorrectly marked. It is evident, however, that some of these 

 beds, if they continue, must abut against the end of the 

 melaphyr of the Village section. This is suggestive of a 

 transverse fault. Farther north the outcrops are so iniperfect 

 on both sides of the line that a lack of correspondence or 

 continuity can not be easily proved. Farther south along the 

 supposed fault line, however, we find evidence which, so far 

 as it goes, is entirely satisfactory. This is afforded by the 

 slate which is mapped as forming a short northwest and 

 southeast line of outcrops south of the end of Hockley 

 Lane. This slate is the purplish variety, with occasional thin 

 streaks of sandstone. It strikes in the direction named and 

 dips N. E. 70°. In the direction of the strike the slate is 

 exposed very near the granite, and it is evident that it is cut 

 off by the granitic rocks on both the east and south. The 

 most careful search fails to reveal any evidence whatever that 

 the granite is intrusive in the slate ; but the most satisfactory 

 explanation of their relations is that proposed on the map. 

 This slate has been somewhat doubtfully referred to the great 

 bed (14) ; and, judging from its dip, it belongs on the south 

 side of the synclinal axis, which implies a shallowing of the 

 trough in this direction. The marked southeasterly strike may 

 be regarded as in some way the result of the transverse dis- 

 placement. 



Having now brought the strata of the Deal's Cove area face 

 to face with those of the Village area, it is readily apparent 

 that they can be correlated only by completely reversing the 

 one series or the other. This is most obvious in the case of 

 the melaphyr, which is on the south in the Village area and 

 on the extreme north in the Beal's Cove area. The entirely
