DEFORM A TION OF ROCKS

these cases, if the dips of the schist observed in crossing a 

 ridge were alone considered, the ridges would unquestionably be 

 called anticlines. Also if the layers of limestone immediately 

 adjacent to the schists were taken into account, the same con-

elusion would be reached (Fig. 2). While the dips in each case, 

 both on the east and west sides of the ridges, are generally to 

 the east (locally west dips are formed on the west sides of the 

 ridges), on the east side of each ridge the dip is flatter than 

 on the west side, thus making a divergence downward. Fortu- 

 nately, however, in the case of Turnip Rock, the limestone at 

 both the north and south ends of the hill is traced to the schist, 

 and is found to plunge under it. In fact, at the south end of 

 the mountain the limestone can be almost continuously traced 

 under the schist, and seen to bend suddenly from an almost flat 

 position to its overturned position. A study of Barack M'Teth 

 and other mountains and their relations shows that Turnip Rock 

 is unquestionably a type of the remainder of the ridges of the 

 district. They are nearly recumbent, slightly fan-shaped syn- 

 clines. In the areas between the schist ridges the limestone 

 has for the greater part of the distances a continuous rather 

 moderate dip to the east. It is only near the east side of the 

 ridges that the sudden turning over of the anticline may be found. 

 A section through two synclinal schist ridges, with intervening 

 limestone, is generalized in Fig. 2. It is to be noted that if the 

 plain of denudation had cut somewhat lower, so as to remove
