This example of a cross reef related to the dyke may occur at other 
points along the line of dyke intrusion, and any gullies to the north and 
south crossed by this dyke would be worthy of prospecting if not already- 
worked. 
The large nuggets were probably shed from rich veins crossing indica¬ 
tors, but the occurrence of this class of igneous dyke is an additional guide 
to the presence of gold-bearing reefs and veins which would be associated 
with it.

GOLD REEFS IN THE VICINITY OF THE OLD 
CEMETERY, BALLARAT. 
By IE. Baragwanath. 
The country in the vicinity of the old cemetery at Ballarat, is occupied 
by Ordovician rocks covered by a varying thickness of soil and surface 
deposits. The westward extension is buried beneath basalt, w T hile to 
tiie north an extensive area of recent deposits obscures the underlying bed¬ 
rock. Eastward the surface levels fall to the depression in which Gnaw 
Creek flows, while southward the margin of the exposed Ordovician is 
flanked by basalt. Lake Wendouree occupies: portion of the south-western 
corner of the area. Numerous patches of scattered quartz occur, and in 
places, as in the old cemetery, quartz reefs are exposed. The southern por¬ 
tion of the area is for the greater part built upon, and gardens, &c., obscure 
the original surface features. North of the railway line there are paddocks 
in which scattered outcrops of quartz show. The area offers exceptional 
inducements for reefing for two reasons, the first being that of position along 
the extension of a favorable belt, and the second the rich alluvial gold 
derived from the denudation of material in the vicinity. 
As regards the position of the area, it will be noticed that it occupies 
the northern extension of the Sebastopol Plateau belt, a belt famous not 
only for the richness of the alluvial, but also for its quartz mines during the 
last half century. 
On the Sebastopol Plateau three quartz reefs have been exploited. The 
Consols lode was worked from the outcrop under the basalt to a depth of 
2,000 feet with profitable results. An endeavour is now being made to 
locate the reef in the South Star mine at a depth of 3,000 feet. The 
auriferous portion of this lode, as worked, extended over a length of 
1 1 miles. East of the lode, in shallow levels, rich spurs and veins were 
worked to a depth of 600 feet. 
A quarter of a mile to the west is the Guiding Star line of lode. Payable 
returns were obtained from this line for a length of ij miles. About a 
quarter of a mile further west is the Albion lode. This reef has returned 
payable results in the Star of the East No. 2 shaft and Band and Albion 
No. 4 shaft. . 
A popular belief exists among many on the field that the northern 
extension of the Sebastopol Plateau belt of country terminates against a 
cross course which is also credited with the loss of the Ballarat East belt 
of country at Black Hill. That this is a fallacy may be easily proved in 
the case of the Ballarat East field, and as regards the Ballarat West portion, 
we have instances of the existence of auriferous quartz north of the supposed 
cross course. Of these perhaps the most significant was met with in the old 
Kohinoor shaft, where from the cap of a reef, still left intact, a nugget of 
gold weighing 834 ozs. and attached to a slab of quartz was obtained. Two
