the south of the intersection of the adit and the reef, a shaft has been 
sunk on the line. Forty-five feet east of the Cedric reef, another line was 
intersected in the tunnel. This line runs parallel to the Cedric reef, and 
has been driven on to the north for a distance of 70 feet. To the north 
of the Cedric adit, a lower adit, length 100 feet, has been put in. This 
adit would intersect the Cedric reef about 340 feet north of the shaft 
referred to above. The adit would have'to be extended about 100 feet 
to cut the main Cedric line. 
At a distance of 66 feet from the mouth of this adit, a diorite dyke 
10 feet wide is intersected. The main belt of auriferous countrv in the 
Wandiligong district is traversed by similar dykes, running approximately 
parallel to the lines of reef. In some cases the reefs are directlv asso¬ 
ciated with the dykes, quartz, often auriferous, occurring on either wall 
Or in the dyke itself. In other cases in following along the line, the dyke 
disappears, a quartz reef taking its place. The dyke showing in the Cedric 
adit has not been traced either way. It traverses ground in which no 
mining has been done. The country in the vicinity of these reefs appears 
favorable for gold, and should repay further prospecting.

ROSE, THISTLE, AXD SHAMROCK MINE, HARRIETVILLE. 
By /. P . L. Kenny. 
The Rose, Thistle, and Shamrock mine is situated about 2 miles north¬ 
west of the township of Harrietville, near the head of Shamrock Creek, 
a tributary of the Ovens on the west side. 
The main Shamrock reef has been worked along the surface for a dis¬ 
tance of about 650 feet. It strikes W. 3 deg. X., and dips to the south at 
62 deg. The strike of both the reef and the countrv rock is much more 
nearly east and west than is usually the case in the district. The general 
strike of the lines of reef is X. 30 deg. W. The Shamrock line is the 
only one of any length running nearly east and west. The reefs run 
approximately parallel to the strike of the enclosing slate and sandstone 
beds. At the face .in the lower Shamrock tunnel which is about 60 feet 
from the line of reef, the countrv rock strikes W. 30 deg. X*., and dips 
S.W. at 67 deg. 
The outcrop of the reef cuts across the Shamrock Creek. The reef has 
been worked on the surface for a distance of 470 feet west from the creek. 
At a distance of 120 feet from the creek the line is cut toff by a fault, the 
strike of which is E. 22 deg. X. The reef was intersected again after 
driving westward along the fault for about 40 feet. At the western end 
of the workings, the reef appears to be cut off by another fault striking 
E. 40 deg. X”. and dipping S.E. at 62 deg. Several cuts have been put 
in beyond this fault, but all in the direction of the original line of reef. 
A piece of quartz showing gold was picked up a short distance to the 
south. It is probable that the continuation of the line will be picked up 
by driving south-west along this fault. The old workings on the Sham¬ 
rock line included several shafts and a tunnel. All the workings on the 
line are now inaccessible, but the following particulars have been supplied 
by the manager, Mr. H. A. Higgs. The main shaft, known as the engine- 
house shaft, was sunk to a depth of 317 feet on the underlay of the reef. 
The old tunnel cut the reef at a depth below the mouth of the engine-house 
shaft of 130 feet vertically, or 147 feet on the underlay of the reef. From 
the end of the tunnel a drive west on the line was put in for a distance of
