high angle south-westward. Farther away from the schists, at the 

 top of the quarry, the flaggy beds bend over, so as to dip eastward. 



North of this point, and about halfway down the slope of the 

 quarry, the sandstone and schists, together with their plane of 

 junction, all dip west-south-westward at an angle of 25°. 



Still farther north-westward (fig. 6, p. 136) the sandstones at 

 the top of the quarry dip west-south-westward. At an angle of 30°, 

 but halfway down the slope, the beds suddenly turn over, and become 

 nearly vertical. These are separated from the Archsean rocks by a 

 thin faulted block of impure brown limestone, followed by a few 

 feet of the flaggy sandstone. The plane of junction of the latter 

 with the schists dips west-north-westward at an angle of 30°. The 

 schists are vertical, striking towards the west-north-west.

Combining the relations seen in these three sections (figs. 4-6, 

 p. 136), the facts may, I think, be explained by supposing the 

 existence of another anticlinal fold of sandstone, faulted against the 

 Archaean massif, and against the more southerly-situated anticline, . 

 and overthrown towards the north-east, as indicated by the dotted 

 lines in the sections. 



At the extreme northern end of the quarry (fig. 7, p. 136) the 

 sandstone again dips west-south-westward at an average angle of 25°; 

 while the schists dip irregularly, in a nearly opposite direction, at a 

 very steep angle. 



About halfway between the points at which sections 6 & 7 were 

 taken, more massive and darker beds of sandstone at the top of the 

 quarry dip east-north-eastward at an angle of 60°. These beds are 

 probably the same as those exposed in the two small quarries in the 

 sketch-map (fig. 2), and are separated by one or more faults from
