and has been stoped right to the surface and also* 30 feet below the level. 
This reef conforms to the country rocks and is a “ leg ” striking N. 
25 deg. W. and dipping 85 deg. W. The shoot in Polar’s Leader is 
northerly, and the shaft is being sunk to cut the shoot on its pitch. 
The Birthday mine is being worked about 10 chains south of the 
Alabama tunnel. It was not examined, but the proprietor informed me 
that there are some interesting examples of faulting in it. 
The Star of the West Mine, Kevington. 
The Star of the West mine is on Mack’s (Creek, 7 miles from Jamieson, 
on the Wood’s Point road. The creek was first’'worked for alluvial gold 
and later on the gold was traced right up to the reef. The country rocks 
(slate and sandstone) are corrugated Silurian beds that strike N. 30 deg. 
W. and dip 85 deg. S.W, near the site of the battery, but in the 
tunnels the rocks dip east in some parts of the mine, though the dip is 
generally to the west. An anticline with saddle reefs shows in No. 1 
tunnel and also in No. 2 tunnel. 
At the south end of No. 1 tunnel there is a distinct saddle reef which 
has been extensively worked right over the anticline. The apex of the 
saddle reef was about 20 feet above the tunnel level. From this level 
the eastern leg has been stoped down to No. 2 tunnel or about 120 feet. 
There appears to have been an overthrust, for as the east leg at No. 1 
level is followed down, it gradually turns until in No. 2 tunnel it is 
a west leg, and it continues dipping west right down to No. 3 tunnel.
