•case of the present locality the dip is 50 deg. to 75 deg. S.W., so that 
the intersections of the dykes with the “leg” reefs pitch to N.W. at a 
rapid rate. 
Sketch Plan of the Homeward Bound Reef, 300-FT. level; Cross-cut 
47 feet S.E. of Shaft. 
The “ legs ” or reefs conforming in dip and strike with the Silurian 
.'beds have cut through the dykes which are faulted. In one case the dyke 
on the northern side of the reef is 80 feet away on the same level from 
the corresponding part on the southern side of the reef. At the contact 
of the reef with the dyke, the quartz expands. It is evident that the 
faulting movement, which has dissevered the dyke, has been along the 
bedding planes of the Silurian strata. As the dykes are persistent it 
would appear that along their course the country should be well prospected 
so as to test the intersections of quartz reefs wherever they occur. 
.Centre-country must be to the north-east of the lines of reef being worked, 
and the intersections of the dykes and centre-country should also receive 
attention. 
There are several old shafts on the lines of reef. The shaft now 
being used is on the Homeward Bound line ; it is 450 feet deep. The 
dimensions are 7 ft. 6 in. by 3 ft. 6 in. to a depth of 300 feet; below 
that it is 10 ft. 6 in. by 3 ft. 6 in. 
At the 300-ft. level the country-rocks dip S.W. at 75 deg. A cross¬ 
cut north-eastward has been driven 47 feet to the reef, which is 2 inches 
thick. Along the reef a level has been driven S. 35 deg. E. for 40 feet 
to the intersection of the dvke and the reef, and it terminates 50 feet in 
from the cross-cut. The strike of the “ leg ” of quartz is N. 35 W., and 
the dip is S.W. at 84 deg. The pitch of the country-rocks is north¬ 
westerly.
