The beds which can be examined above the slide appear to dip 70 deg. 
to the west in the north-east cross-cut 15 feet from the rise, but where 
I could note them elsewhere they had a dip of 60 deg. to 70 deg. to the 
east. 
Mr. Osborne informed me that in sinking the main shaft an anti¬ 
clinal fold was cut at 120 feet deep, but the close timbering now obscures 
this from view, although an anticline should occur near the shaft as there 
are western beds in the gully to the west of the shaft. 
The slide is strong, having black pug along it and crushed beds above, 
showing it has been the upper portion of the country which has moved on 
the lower. The direction of the movement cannot be definitely stated, 
but it is probably to the east, as a little quartz has been seen near the 
slide that way. 
To the west of where the reef was lost the country has been already 
tested to some extent by a cross-cut; and the main shaft showed nothing 
below where the slide cut through it at 60 feet, but there is still a portion 
of the ccuntrv to the west of the shaft of which nothing is known. 
If, as seems probable, the lower portion of the reef lies to the east, 
then it will have to be looked for to the east of where the slide goes under¬ 
foot in the 150-ft. level, and this would necessitate further sinking of 
the main shaft, and cross-cutting out towards the slide again. This 
would be purely prospecting work, as no estimate can be formed of the 
amount of movement. 
Whatever future work the party decide to carry out in trying to locate 
the reef, they must take carefully into consideration the westward dip 
of the reef, and particularly its pitch to the south. On account of its 
shortness this reef will be much harder to locate than if it had been in 
a better-defined channel extending for some distance. 
Yields up to ?\ ozs. to the ton have been obtained, and the two last 
crushings gave— 
25 tons for 32 ozs. 15 dwts. 
30 ions for 48 ozs. 7 dwts. 
The present party have only earned about £11 per man for their 
six months' work, for after paying heavy expenses in putting up the whim 
and sinking a main regulation shaft there was little profit left from the 
crushings. At present the water can be kept down by a few hours baling 
with the tanks each day.

THE ADMIRAL SPERRY REEF, NEAR ROCKY LEAD. 
By W. H. Ferguson. 
The Admiral Sperry reef, which has recently been found and pro¬ 
spected by Mr. W. Macane, of Wombat, is centrally situated between the 
townships of Wombat, Barkstead, and Rocky Lead. The strike is 
N. 17 deg. W., and the dip is to the west, at 75 deg. to 80 deg.; the 
reef agrees in both strike and dip with the country rock, which is Ordo¬ 
vician slates and sandstones. From this reef quartz leaders a few 
inches in thickness dip to the north-east at about 58 deg. and pitch to 
the north about 25 deg.; along the junction of these leaders with the 
vertical reef the latter appears to have been richer in gold. The reef 
has been worked on a pitch to the north to a depth of 35 feet; it varies 
in thickness from a few inches to 3 feet, which is now the thickness of
