but are sharply bent and ruptured. Along these anticlines the rocks are 
much shattered, and quartz, as spurs irregularly crossing the beds, is 
abundant.

Plan of Part of Brockwell and Grigson’s Claim. 
In relation to the indicators, these anticlines are of great value, for 
where a set of quartz veins has been found to carry gold along the course 
of, say, an easterly indicator, the continuation of the same indicator should 
be searched for on the W. side of the anticline, or centre-country, for the 
indicators, being, beds, are bent over with the other beds, and the import¬ 
ance of these relations will be seen by the attached plan ana section of 
Brockwell and Grigson’s claim. In this case the Caledonian indicator has 
been worked on the E. side of the anticline for several hundred feet in 
length, and down to from 45 to 60 feet from the surface, where it was 
cut off by a fault dipping N.W. The owners of the claim have worked 
on this E. indicator for some distance, and now have a shaft sunk to a 
depth of 125 feet. They have cut this same indicator in the bottom, but 
they were unaware of the proximity of centre-country, and did not know 
that the indicators should recur to the W. of the centre-country. 
There are already three indicators proved on the E. side of centre- 
country. One is in a shallow shaft, a little S. of this deep shaft, where 
the indicator is about 3 feet E. of the axial line; the second is the Cale¬ 
donian indicator, 90 feet E. of centre-country; 6' feet further E. is the 
third indicator. But this country has never been systematically prospected 
for indicators. When it is there is reasonable prospect of proving a 
succession of them, such as occur in the Ballarat East mines. 
This gold-field requires a careful detailed survey as part of any plan 
to minutely survey and elucidate the rock structure of the whole tract of
