fold plunges. In view of this, even though the turn extends 

 westward for a considerable distance, it has been thought best to 

 neglect it and to base the measurement of displacement upon the 

 general strike. But the south end of division iii is not faulted 

 at all, being merely dragged. Hence the axis of the north anti- 

 cline is plotted as displaced 70 feet, an amount proportional to 

 its distance from the south end of the faulted area. At the 

 Copper lead, a total displacement of 95 feet gives a negative 

 overlap of 20 feet, and an offset of 92.5 left. The north anti- 

 clinal axis has a negative overlap of 17.5 feet and an offset of 

 66.75 feet left. 



At and near the eastern end of the quarry, area 71, the fault 

 could be seen in three places in 1899. The most northern was 

 a small pit nearly in the centre of area 71, where it dips 68° E. 

 (pi. 9, fig b). The strata east of the fault are here nearly hori- 

 zontal, for the more southerly of the two anticlines which form 

 the large subsidiary one broadens and flattens westward. The 

 second exposure of the fault was in a circular pit east of the large 

 quarry, and topographically several feet lower than the first. 

 Here it is essentially perpendicular. Its direction changes errati- 

 cally in the fifteen feet of section, being at the south end of the 

 pit N. 60° E., and at the north end E.-W. (pi. 11, fig. h). At 

 the east end of the quarry itself, or rather in a short cave exca- 

 vated eastward from it, the break is again visible. In the second 

 pit just mentioned, the hanging wall lead of the Jo. Taylor belt 

 comes up on the east at a liigh angle (pi. 9, fig. a). It is said to 

 have been tunnelled east to the small fault on area 72, meeting 

 underground workings east of that point. The total horizontal 

 displacement at this point is 37.5 feet. The overlap and offset 

 are difficult to measure, on account of the curved strike of the 

 Taylor belt west of the fault. If this were due merely to drag, 

 the problem would be simple ; but north of the local anticlinal 

 axis west of the break th ? strike is northwest, showing that the 

 strata really plunge downward toward the east (pi. 18.)
