further on is a very small outlier, less than i chain across. A more ex¬ 
tensive outcrop, about 30 chains long and several chains wide, is situated 
2 miles from the Gap. The limestone is compact and of bluish-grey 
colour, but the colour is against its use for ornamental purposes. The 
height is about 1,800 feet above sea-level. About J mile up Wombat 
Creek from its junction with Mitta Mitta River is another small outcrop 
of similar limestone, and close by is a mass of Devonian conglomerate 
standing on edge and projecting several feet above the surface, thus form¬ 
ing a very conspicuous object. This conglomerate is apparently just 
above the limestone as regards age, and it extends away for a long dis¬ 
tance to the north from this point. Between this outcrop and the Mitta 
Mitta River another limestone outcrop occurs. 
On the eastern side of the Mitta Mitta River, and 20 chains above the 
junction of Wombat Creek, which joins it from the west, there is a bold 
outcrop of limestone, which rises as a bluff directly from the river to a 
height of about 200 feet. The face along the river bank is about 400 feet 
wide. Much of the surface is covered with stalactitic material, and por¬ 
tions of the limestone, that appear to be due to secondary deposition of 
limestone, are impregnated with iron pyrites and copper pyrites. There 
does not appear to be any defined lode, but certain irregular portions carry 
the ore. In places the pyrites attains a thickness of 1 inch, but only for 
3 or 4 inches in length. Some slight quarrying has been done both on 
the river face and on the top of this mass, but the appearances do not 
encourage further prospecting. 
In colour this mass is bluish-grey, like the other outcrops. The texture 
is compact, and it might be utilized if near a centre of population, but its 
remote situation precludes its use for the present. It would burn into 
excellent lime, but there is no local demand. 
Just to the north of the limestone is a remarkable mass of Devonian 
conglomerate, which stands on edge and rises as crags for 200 feet above 
ihe river. This conglomerate is stratigraphically above the limestone, and 
appears to be separated from it by calcareous and fossiliferous mudstones. 
On the • southern side of the limestone, and’ therefore lower in the rock 
series, are, first, fossiliferous mudstones, then slates and sandstones, all 
of Silurian age. Fossils were observed in all the outcrops of limestone, 
and a few examples were secured for identification. 
Resting on the upturned edges of the limestone and conglomerate beds 
are the Cainozoic conglomerates, &c., of an old lead, and, covering this, 
a flow of Older Basalt. This locality is one that should be carefully 
worked out, for clear sections showing the relations of the agglomerate, 
the slates and sandstones, the limestone, and the overlying conglomerate 
should be obtainable. Mr. W. H. Ferguson, I believe, reported on this 
limestone, but his report has not been published.

DANE’S CREEK SILVER-LEAD LODE, NEAR THE MITTA 
MITTA RIVER. 
(NO. 20 ON LOCALITY MAP.) 
By E. J. Dunn , F.G.S., Director , Geological Survey. 
About 3 miles in a southerly direction from Dartmouth is the site of 
prospecting operations carried on by Mr. Cotton. The country up to this 
point from the Dark River consists for 2 miles of agglomerate, then a 
belt of slate \ mile wide, and 1 then agglomerate up to the lodes being tested. 
The height above sea-level at the lodes is about 1,250 feet.
