to conditions observable in the Cambrian areas of southern New Bruns- 



Strata ar- wick. In the Barachois basin, though the succession of members of 

 ranged trans- 

 verse to a the terranes is in ascending order from the north-east to the sou th- 



prelsureffroin westi > tne cleavage planes are at right angles to this and so parallel to 

 the S.E. the direction of the pressure referred to. 



So also in Indian brook basin, for the greater part of its length the 

 Cambrian terranes are arranged in a single succession transverse to 

 the valley, having been folded parallel to the valley and tranverse to 

 the crowding pressure from the south-east. The Cambrian rocks of 

 this valley, for the greater part of its length, display simply the north' 

 east slope of a synclinal fold, of which the opposite slope has been 

 uplifted and entirely removed by erosion in the long ages that have 

 passed since Cambrian time. The pre- Cambrian platform on which 

 this part of the fold rested, now stands up as a high ridge on the south 

 east side of the valley, cutting it off from connection with the Cambrian 

 basins along the shore of East bay. 



Again, in the valley of the Mira river, overturned dips are prevalent 

 along its south-eastern side, especially in the Etcheminian terrane, as 

 may be seen on examination of Mr. Fletcher's map of that district. 

 The whole series of the older Palaeozoic terranes along the north west 

 side of the Mira valley also, are seen to dip seaward without over- 

 turned dips, and in the middle of the valley the anticlinal and synclinal 

 folds are in a general way parallel to the Cambrian basins further to 

 the north-west, so that the parallelism of structure of the ridges and 

 valleys existing in pre-Cambrian times, along this coast, continued to 

 be emphasized by a continuance of the pressure in the post-Cambrian
