Von Moltke Reef. 
This is situate on the eastern slope below the Homeward Bound Reef, 
and right over the tunnel with which a shaft connects. This shaft is 
about 200 feet deep. The strike of the reef is about N. and S., but very 
tortuous, apparently displaced by faults; the dip is to the W. The 
country rocks strike X. 15 deg. W., dip 87 deg. to W., and pitch 7 deg. 
to X. The quartz worked was from 6 inches to 2 feet thick. 
“ The Dyke.” 
On the Mount Stanley Road, half a mile from its junction with the 
road from Stanley to Hillsborough, an outcrop of granite occurs on the 
southern side of the road, while surrounding it are altered sandstones— 
much indurated Ordovician beds', apparently altered by contact 
with the granite mass. Most of the granite outcrop is extremely hard, 
but the northern portion is decomposed. In the softer portion there are seve¬ 
ral small quartz veins, ranging from J inch to 3 inches in thickness. These 
have been worked to shallow depths in several places, and one shaft has 
been sunk on such’ a vein for 60 feet in depth. The extreme N.E. corner 
of the outcrop has been trenched for a few feet in depth, in following 
these small quartz veins, but apparently they did not contain sufficient 
gold to be worked profitably. The strike of most of these quartz veins 
is nearly E. and W., and they are almost vertical. The locality is 
interesting, as one in which gold occurs in veins intersecting granite. 
Mount Stanley View Reef. 
Two hundred yards to the north-west of the granite outcrop above 
described in the Mount Stanley View Reef in metamorphosed sandstones, 
&c., worked bv Mr. Johnson, of Stanley, and from which ^2,000 worth 
of gold is said to have been taken. The reef has been worked at the 
surface for a length of about 200 feet, and to a depth of 150 feet. I am 
informed that the strike of the reef is X. and S. (magnetic), and the dip 
to W. The quartz was from 6 inches to> 2 feet thick. In a northerly 
direction the course of the reef is traceable for some distance, but there are 
no workings on it. Southerly the reef is heavilv faulted and thrown to 
the W. Two disjointed blocks have been worked in this direction.

REPORTS ON GRAPTOLITES, WITH PLATE; FIGURE AND 
MAP—(PLATE XXXIV.). 
By T. S. Hall , M.A. {Melbourne University). 
From Turquoise Mine , Ryan’s Creek , 
Myrrhee. 
(No. 336-343. Collected by Mr. A. M. Howitt.) 
Specimen No. 338 contains examples of Diplograptus sp. and No. 339 a 
Dendrograptus , but the state of preservation : s too poor to allow of closer 
determination. There appear to be indefinite traces of graptolites on the 
other slabs. The evidence submitted is not sufficient to fix the age of the 
contaimng rocks. The probability is that they are either Upper Ordovician 
or else Lower Silurian.
