Kangaroo Mine. 
At the Kangaroo mine, over which we were shown by Mr. Bryant, 
saddle-reefs have been worked for the last eighteen months, and Mr. 
Bryant has extended these workings. The Kangaroo Company holds a 
tribute over 500 feet in length by 400 feet in depth of the Williams Fancy 
lease, at the northern end, and its operations extend into this ground. 
In the No. 3 level of the Kangaroo shaft, which is 225 feet from the 
surface, and 800 feet south from the shaft, in the tribute portion of the 
workings in the stopes, 20 feet above the level, there is well-formed centre- 
country (anticline), and a saddle-reef measuring 10 feet across the saddle 
and 10 feet high from the cap of the saddle to the cap of the reef. This 
quartz is all sent to the crushing machine, and is very profitable to work. 
The general pitch of the reef is to the south, so that this same reef should 
be found at a deeper level by cross-cutting west from the Williams Fancy 
shaft. There is another saddle-reef, 1 ft. 6 in. thick, carrying excellent 
quartz, 23 feet below the 10-foot saddle reef; while 9 feet above this one 
is a small saddle-reef, 3 inches thick, but profitable to work. These three 
saddle-reefs are south of a cross-course, striking N.E., and dipping to 
S.E. at 5 deg. At the cross-course, and to the west of\ No. 3 level, a 
small saddle-reef, 8 inches thick, is disclosed. This has been driven on 
for 20 feet to the north. The pitch is to the south, and the quartz is 
payable. This is the only attempt that has been made to work the saddle- 
reefs above the No. 3 level, and north of the cross-course. 
The No. 4 level is 90 feet below the No. 3 level. To the north of the 
cross-course, and within the Kangaroo lease, is a cross-cut to the west of 
the shaft, and 700 feet along the level, to the south. Centre-country occurs 
70 feet to the west along this cross-cut. It has two well-formed saddle- 
reefs—the top one 1 ft. 3 in. thick, and the under reef 6 inches thick. The 
quartz of both reefs pays well for extraction. 
In the same level, 400 feet south of the shaft, and 21 feet west of the 
cross-cut, in a rise 18 feet above this level, there is a sandstone saddle, 
pitching to the south. The saddle-reef is 8 feet thick and 26 feet wide 
across the saddle, with slate over the reef. Taken in a face, this quartz 
yields about 6 dwts. of gold per ton, and is very profitable to work. 
In this mine the countrv-rocks consist largely of very favorable-looking 
slate beds. As these occur along the anticline, they are lower down in the 
series than the thick sandstone and olive-green slates that form such a 
characteristic feature in the country worked to the east of centre-country 
trom Berringa to Scarsdale. These slates along the anticline are more 
favorable for gold than the sandstone, in which most of the mining has 
hitherto been done. As regards the horizon of the Berringa beds, all is 
uncertainty. Probably they belong to a horizon higher than the Bendigo 
zones. Until some fossils are discovered, or some other link obtained, the 
proper position of these beds in the miles of thickness of Ordovician rocks 
must remain problematical. 
Birthday Tunnel Mine. 
In the No. 3 level, and north of the cross-course, centre-country is dis¬ 
closed. A saddle-reef is being worked 400 feet north of the shaft, 30 feet 
south, and 50 feet above the level in the stopes. This reef is 30 feet 
across the saddle, and 6 feet high above the cap of the saddle. On the 
western side the leg is being worked down forborne distance, the quartz 
varying from 6 feet to 8 feet in thickness. The whole of the quartz from
