the auriferous shoots are well worth working, and the locality promises 
well, and is well deserving of further prospecting. It is as yet premature 
to think of installing a battery, but if the present prospects continue, when 
some further opening up of the several sites has been done, a battery will 
be needed. 
For economical crushing and mining this tract has special facilities, as 
water power can be utilized for crushing purposes, and mine timber and 
fuel are abundant. The effort being made to open up these reefs deserves 
every encouragement.

THE DARLING GRANT REEF, GRANITE CREEK, NEAR 
MYRTLEFORD. 
By E. /. Dunn , F.G.S., late Director , Geological Survey. 
The Darling Grant reef is on Granite Creek and about 8 miles north¬ 
easterly from Myrtleford. The surrounding rocks are metamorphosed 
Ordovician, and granite outcrops a short distance to the northward. The 
strike of the beds is about N. 15 0 W. and their dip is westerly at 8o°. 
The surface soil is red. Where the reef was worked at the south 
end, the foot-wall was softer than the hanging-wall. The strike of the reef 
is N. io° E., dip 70° W. From this southern block a considerable 
quantity of quartz has been removed and it is said to have given a good 
return. A short tunnel has been driven below the open workings and 
quartz stoped out below, but to what extent could not be determined. 
The shoot of quartz appears to have pitched northwards. The block was 
about 130 feet long and is cut off by a fault, at the northern end, and 
then the continuation was thrown about a chain to the north-west, where 
the second block was worked for 1 chain in length. The reef was from 
1 to 2 feet wide and was stoped to over 100 feet in depth. The strike 
of this part of the reef is W. 20° N. From both the blocks worked 
the surface has been sluiced for some distance down the hill, showing 
that a considerable quantity of gold was shed from the reef. The height 
of the top workings above sea level is about 1,470 feet. 
With the object of cutting the shoot of auriferous quartz at a lower 
level, a tunnel (cross-cut) was driven in from the north-west at 250 feet 
below the top workings. At 600 feet a wall striking W. 20° N. 
and dipping 70° S. was cut. This wall corresponds to the wall of the 
second block of quartz in the top workings, but there was no quartz on 
it. The wall was driven on for 60 feet in a westerly direction and was 
then lost in broken country; easterly the level was continued along a good 
wall for 75 feet where it is cut off by a fault; this fault should have "been 
followed in a northerly direction until the wall was again struck, probably 
less than 100 feet along the fault. Instead, the level was driven 200 
feet through the country rock in a south-westerly direction nearly parallel 
to the wall, and turning easterly towards the end, but without any result, 
as neither the reef nor its channel was cut. 
The conditions that prevail here scarcely warrant further prospecting, 
but should further work be undertaken it should be in a northerly direc¬ 
tion along the fault which at 75 feet from the end of the tunnel cuts off 
the wall.
