at the adit level. The reef here has a bumpy wall nearly vertical, and 
dips sometimes to the east, and sometimes to the west. The line carries 
a little quartz up to 6 inches thick in places. At a distance of 48 feet 
from the mouth, a dyke shows on the western side of the reef for a length 
of 47 feet; the dyke then bears more to the west than the reef, being 
intersected again in a cross-cut west, at the end of the drive. 
The dyke is about 12 feet wide, and does not show on the eastern 
side of the Trident wall. The lower adit has been driven on the Trident 
line for a distance of 196 feet. At this point a line was cut striking 
more to the west. The arive has been continued on this western line. 
The eastern line is here the probable Trident wall, and carries a little- 
gold. The line strikes W. 30 deg. N., and dips easterly at 80 deg. It 
carries 1 foot of quartz at the junction. A drive on this line for 40 feet 
should cut the shoot worked above. The drive on the western line has 
been continued another 100 feet. Very little quartz having been found, 
a southerly cross-cut has been put in at the end of the drive with the 
object of cutting the western reef. This cross-cut is now in 60 feet, 
and, with its present bearing, would have to be driven 116 feet further 
to cut the western reef. By continuing the cross-cut with a bearing 50 deg. 
nearer west than it has at present, the reef would be cut in about 7c 
feet. 
The dyke passed through in the upper adit shows 12 1 feet wide in this 
cross-cut. The country rock is much distrubed in its vicinity, and the 
dyke appears to occupy the centre of an anticlinal fold.

THE REFORM REEF. MYRTLEFORD. 
By E. J. Dunn , E.G.S., Director, Geological Survey. 
This reef adjoins the town on the north side. The strike of the north 
end of the reef is N. 20 deg. W. ; dip 60 deg. W. ; strike of country 
rock N. 30 deg. W. The strike: of the country rock where the steam winch 
stands at the mouth of underlay shaft and where the principal work has been 
done, is N.W. ; dip W. 70 deg. The reef dips about 60 deg. W. at this 
site, and it cuts through the beds both in strike and dip. Pitch of footwall 
northward. Pitch of shoots of gold south about 45 cleg. The pitch of 
the hanging wall was not clear. 
o o 
The country rock consists of yellow, grey and pink slate, and brown 
and grey sandstones. Some of the hard unaltered bluish-grev sandstones 
from a depth are interlaced with quartz spurs. 
A main tunnel (cross-cut) has been driven in from the main street of the 
town to the reef, and levels were then driven north and south. Xear the 
end of this tunnel, in the level, an inclined shaft followed the shoot of 
gold down in a southerly direction at an angle of about 45 deg. Another 
inclined shaft was sunk from the outcrop where the steam winch stands, 
and this followed the shoot of auriferous stone down for about 500 feet 
below the tunnel. The outcrop of reef has been worked at several places 
along its strike and within a distance of about half-a-mile. The continua¬ 
tion of the lode in a northerly direction does not appear to have been 
searched for verv thoroughly. In this direction it passes under the alluvial 
ground of Myrtle Creek ; in a southerlv direction it would pass below the 
alluvia] of the Ovens River.
