-and the mine and plant were sold for a small sum, the present company 
-being the purchasers. The English company did not sink a centre-country 
winze, and that work has not yet been done. 
The present company sank the shaft to 1,725 feet, and should this pre¬ 
sent find prove profitable to work it will give a great impetus to this end of 
the field. The importance of the discovery of auriferous quartz in this 
mine lies in the fact that this is the most southern mine on the field. As 
conditions similar to those nearer the city prevail here, there appears to. be 
every reason why in time equally great activity should prevail in mining. 
One of the drawbacks of deep mining is that there are years of persistent 
work ahead before a return can be hoped for, but once it is realized that, 
with sufficient capital to begin with, there are such good.chances of success, 
even that drawback will not greatly retard the development of mining at this 
end of the field. 
The shaft of the Great Southern mine is well placed, and there is every 
reason to expect that as sinking and cross-cutting are extended many saddle- 
reefs will be encountered. 
I am greatly indebted to Mr. Mining Inspector Abraham and to the 
manager of the mine for their courtesv and assistance.

CERTAIN MINING OPERATIONS AT BENDIGO. 
(no. 8 ON LOCALITY MAP.) 
By E. J. Dunn, F.G.S., Director, Geological Survey. 
Mr. EL S. Whitelaw is about to continue the survey of the anticlines 
to the southward of the block in which they were laid down by me in 1892, 
and I went over the continuation southward of the Nell Gwynne line with 
him. There will not be any great difficulty in following this line out to the 
south of Sheepwash Creek, but still further to the south the rock will 
probably run through an alluvial flat where no outcrops of rock will serve as 
a. guide. The difficulty along this portion can be overcome by running 
out the parallel lines further to the westward, and then approximating the 
position of the Nell Gwynne line. The same structure in the country no 
doubt continues on to Strangways, but the direction and amount of pitch will 
determine whether the auriferous zones are within easy reach of the miner 
or not. 
Already leases have been taken up southward, as much as 9 miles from 
Bendigo. 
On the Gold-fields No. 1 lease a well-timbered shaft of three compart¬ 
ments has been sunk to a depth of 53 feet, but, unfortunately, this is 
wrongly placed, as it is in westerly dipping strata, and near the syncline, in¬ 
stead of being in easterly dipping strata, and 100 to 200 feet to the east of 
the anticline. The shaft appears to be between the Nell Gwynne and the 
Napoleon lines, being some hundreds of feet to the west of the former and 
250 feet to the east of the latter line. When the Nell Gwynne line is sur¬ 
veyed this far the correct position for the shaft can be determined. 
At Bendigo, the permanent shafts should not be sunk in beds dipping 
westward. They should be sunk in strata dipping east, and about 200 feet 
to the east of the anticline, if centre-country is to be cut at about 2,000 feet 
in depth. This insures short cross-cuts. The pitch of the Nell Gwynne
